Individuals with Parkinson's disease (PD) can have difficulties with activities of daily living (ADL) that stem from cognitive, motor, or affective manifestations of the disease. Accurately attributing ADL difficulty specifically to cognitive decline is critical when conducting a neuropsychological evaluation of a person with PD. Informant description of ADL performance is frequently used for this purpose, but there has been little work assessing informants' ability to attribute ADL dysfunction to a specific symptom source in PD. Fifty community dwelling individuals with PD completed cognitive, motor, and affective measures. A knowledgeable informant completed an ADL scale that asked about degree and perceived source of difficulty (cognitive, motor, affective) for each task. Informants indicated that motor dysfunction was the most common source of ADL difficulty, but the informants viewed difficulty with certain tasks, such as financial management, as particularly related to cognitive dysfunction. Informant reports of the source of ADL dysfunction (cognitive, motor, affective) were consistent with clinical measures of those specific dysfunctions. ADL dysfunction attributed to cognition specifically (χ(2) = 9.80, p = .01) was higher in those with measurable cognitive impairment. Informant reports of the sources of ADL dysfunction correlate with clinical measures of these symptoms, suggesting that informants may provide useful clinical information about the cause of ADL dysfunction in persons with PD.

People with chronic obstructive pulmonary disease (COPD) present symptoms such as dyspnea and fatigue, which hinder their performance in activities of daily living (ADL). A few multitask protocols have been developed to assess ADL performance in this population, although measurement properties of such protocols were not yet systematically reviewed. Areas covered: Studies were included if an assessment of the ability to perform ADL was conducted in people with COPD using a (objective) performance-based protocol. The search was conducted in the following databases: Pubmed, EMBASE, Cochrane Library, PEDro, CINAHL and LILACS. Furthermore, hand searches were conducted. Expert commentary: Up to this moment, only three protocols had measurement properties described: the Glittre ADL Test, the Monitored Functional Task Evaluation and the Londrina ADL Protocol were shown to be valid and reliable whereas only the Glittre ADL Test was shown to be responsive to change after pulmonary rehabilitation. These protocols can be used in laboratory settings and clinical practice to evaluate ADL performance in people with COPD, although there is need for more in-depth information on their validity, reliability and especially responsiveness due to the growing interest in the accurate assessment of ADL performance in this population.

Lower occupational class correlates with a higher disability risk later in life. However, it is not clear whether the demands made by mental and physical work relative to individual resources in midlife predict well-being in old age. This study investigated prospectively whether work ability in midlife predicts disability severity in activities of everyday living in old age. Data come from the population-based 28-year follow-up called Finnish Longitudinal Study of Municipal Employees. A total of 2879 occupationally active persons aged 44-58 years answered a questionnaire on work ability at baseline in 1981 and activities of daily living in 2009. At baseline, perceived work ability relative to lifetime best was categorized into excellent, moderate, and poor work ability. At follow-up, disability scales were constructed based on the severity and frequency of difficulties reported in self-care activities of daily living (ADL) and instrumental activities of daily living (IADL). There was a graded prevalence of ADL and IADL disability severity, according to excellent, moderate and poor midlife work ability (p<0.001). Employees with moderate midlife work ability had an 11 to 20% higher mean ADL or IADL disability severity score, compared with those with excellent midlife work ability (reference), incidence rate ratios (IRR) ranging from 1.11 (95% CI 1.01-1.22) to 1.20 (95% CI 1.10-1.30). Those with poor midlife work ability had a mean ADL or IADL disability severity score 27 to 38% higher than the referent, IRRs ranging from 1.27 (95% CI 1.09-1.47) to 1.38 (95% CI 1.25-1.53). Adjusting for socio-economics, lifestyle factors and chronic diseases only slightly attenuated the associations. Work ability, an indicator of the de- mands made by mental and physical work relative to individuals' mental and physical resources, predicted disability severity 28 years later among middle-aged municipal employees.

To investigate the effectiveness of an exercise program in improving ability to perform activities of daily living (ADLs), physical performance, and nutritional status and decreasing behavioral disturbance and depression in patients with Alzheimer's disease (AD). Randomized, controlled trial. Five nursing homes. One hundred thirty-four ambulatory patients with mild to severe AD. Collective exercise program (1 hour, twice weekly of walk, strength, balance, and flexibility training) or routine medical care for 12 months. ADLs were assessed using the Katz Index of ADLs. Physical performance was evaluated using 6-meter walking speed, the get-up-and-go test, and the one-leg-balance test. Behavioral disturbance, depression, and nutritional status were evaluated using the Neuropsychiatric Inventory, the Montgomery and Asberg Depression Rating Scale, and the Mini-Nutritional Assessment. For each outcome measure, the mean change from baseline to 12 months was calculated using intention-to-treat analysis. ADL mean change from baseline score for exercise program patients showed a slower decline than in patients receiving routine medical care (12-month mean treatment differences: ADL=0.39, P=.02). A significant difference between the groups in favor of the exercise program was observed for 6-meter walking speed at 12 months. No effect was observed for behavioral disturbance, depression, or nutritional assessment scores. In the intervention group, adherence to the program sessions in exploratory analysis predicted change in ability to perform ADLs. No adverse effects of exercise occurred. A simple exercise program, 1 hour twice a week, led to significantly slower decline in ADL score in patients with AD living in a nursing home than routine medical care.

To describe demographical variables, and to study functional ability to perform activities of daily life in adults with osteogenesis imperfecta (OI). Population-based study. Ninety-seven patients aged 25 years and older, 41 men and 56 women, were included. For the demographical variables, comparison was made to a matched control-group (475 persons) from the Norwegian general population. Structured interviews concerning social conditions, employment and educational issues and clinical examination were performed. The Sunnaas Activities of Daily Living (ADL) Index was used to assess the ability to perform ADL. The prevalence of clinical manifestations according to Sillence was in accordance with other studies. Demographical variables showed that most adults with OI are married and have children. They had a higher educational level than the control group, but the employment rate was significantly lower. However, the rate of employed men was similar in both groups. Adult persons with OI achieved a high score when tested for ADL. Adults with OI are well educated compared with the general population, and most of them are employed. High scores when tested for ADL indicate that most of them are able to live their lives independently, even though there are some differences according to the severity of the disorder.

Occupational therapy intervention to inspire self-efficacy in a patient with spinal ataxia and visual disturbance

We report a case of a patient with severe ataxia and visual disturbance due to vitamin E deficiency, whose self-efficacy was inspired by intervention with an appropriate occupational therapy activity. Before the handloom intervention, her severe neurological deficits decreased her activities of daily living (ADL) ability, which made her feel pessimistic and depressed. The use of a handloom, however, inspired her sense of accomplishment because she could perform the weft movement by using her residual physical function, thereby relieving her pessimistic attitude. This perception of capability motivated her to participate in further rehabilitation. Finally, her eager practice enhanced her ADL ability and quality of life (QOL). The result suggests that it is important to provide an appropriate occupational therapy activity that can inspire self-efficacy in patients with chronic refractory neurological disorders because the perception of capability can enhance the motivation to improve performance in general activities, ADL ability and QOL.

One important limitation of prior studies examining functional decline in Huntington's disease (HD) has been the reliance on self-reported measures of ability. Since report-based methods can be biased by lack of insight, depression, and cognitive impairment, contrasting self-reported ability with measures that assess capacity may lead to a more comprehensive estimation of real-world functioning. The present study examined self-reported ability to perform instrumental activities of daily living (iADLs) and performance-based financial management capacity in 20 patients diagnosed with mild-moderate Huntington's disease (HD) and 20 demographically similar healthy adults. HD patients reported significantly greater declines in their ability to manage finances. On the capacity measure of financial management, HD patients performed significantly below healthy adults. Additionally, in the HD group there were no significant correlations between self-reported ability and capacity measures of financial management. HD patients endorsed declines in global iADL ability and exhibited deficits in functional capacity when performing a financial management task. Capacity measures may aid in assessing the extent to which HD patients accurately estimate real-world iADL performance, and the present findings suggest that such measures of capacity may be related to the cognitive, but not motor or affective, symptoms of HD.

The number of older adults in the global population is increasing. This demographic shift leads to an increasing prevalence of age-associated disorders, such as Alzheimer's disease and other types of dementia. With the progression of the disease, the risk for institutional care increases, which contrasts with the desire of most patients to stay in their home environment. Despite doctors' and caregivers' awareness of the patient's cognitive status, they are often uncertain about its consequences on activities of daily living (ADL). To provide effective care, they need to know how patients cope with ADL, in particular, the estimation of risks associated with the cognitive decline. The occurrence, performance, and duration of different ADL are important indicators of functional ability. The patient's ability to cope with these activities is traditionally assessed with questionnaires, which has disadvantages (eg, lack of reliability and sensitivity). Several groups have proposed sensor-based systems to recognize and quantify these activities in the patient's home. Combined with Web technology, these systems can inform caregivers about their patients in real-time (e.g., via smartphone). We hypothesize that a non-intrusive system, which does not use body-mounted sensors, video-based imaging, and microphone recordings would be better suited for use in dementia patients. Since it does not require patient's attention and compliance, such a system might be well accepted by patients. We present a passive, Web-based, non-intrusive, assistive technology system that recognizes and classifies ADL. The components of this novel assistive technology system were wireless sensors distributed in every room of the participant's home and a central computer unit (CCU). The environmental data were acquired for 20 days (per participant) and then stored and processed on the CCU. In consultation with medical experts, eight ADL were classified. In this study, 10 healthy participants (6 women, 4 men; mean age 48.8 years; SD 20.0 years; age range 28-79 years) were included. For explorative purposes, one female Alzheimer patient (Montreal Cognitive Assessment score=23, Timed Up and Go=19.8 seconds, Trail Making Test A=84.3 seconds, Trail Making Test B=146 seconds) was measured in parallel with the healthy subjects. In total, 1317 ADL were performed by the participants, 1211 ADL were classified correctly, and 106 ADL were missed. This led to an overall sensitivity of 91.27% and a specificity of 92.52%. Each subject performed an average of 134.8 ADL (SD 75). The non-intrusive wireless sensor system can acquire environmental data essential for the classification of activities of daily living. By analyzing retrieved data, it is possible to distinguish and assign data patterns to subjects' specific activities and to identify eight different activities in daily living. The Web-based technology allows the system to improve care and provides valuable information about the patient in real-time.

Good housing solutions are important for the ageing population in order to promote health and maintain functional ability. The objective of this study was to investigate whether and how objective and perceived aspects of housing were related to perceived health among ADL independent and ADL dependent groups of older, single-living people within three national samples. The current study was based on national samples (German, n = 450; Latvian, n = 303; Swedish, n = 397) from the European ENABLE-AGE Project, using data on ADL dependence, perceived health, objective and perceived aspects of housing. Descriptive statistics, correlations and multivariate ordinal regression models were used to analyze the data. The participants in the ADL dependent groups generally were older, had more functional limitations and perceived their health as poorer compared to ADL independent groups. With regard to perceived housing, usability as well as meaning of home indicators was often lower in the ADL dependent groups, housing satisfaction was at the same level while housing-related external control beliefs were higher. The differences among the national samples were highly significant for both ADL groups, for all variables except number of outdoor environmental barriers in the ADL independent groups. The relations between perceived health on one hand and objective and perceived aspects of housing on the other show great diversities among the ADL groups and the national samples. The results serve to alert health care practitioners that it is important to draw attention to how older people perceive their housing situation and to the fact that different levels of functional independence demand different interventions.

Effects of impairment in activities of daily living on predicting mortality following hip fracture surgery in studies using administrative healthcare databases

PubMed Central

2014-01-01

Background Impairment in activities of daily living (ADL) is an important predictor of outcomes although many administrative databases lack information on ADL function. We evaluated the impact of ADL function on predicting postoperative mortality among older adults with hip fractures in Ontario, Canada. Methods Sociodemographic and medical correlates of ADL impairment were first identified in a population of older adults with hip fractures who had ADL information available prior to hip fracture. A logistic regression model was developed to predict 360-day postoperative mortality and the predictive ability of this model were compared when ADL impairment was included or omitted from the model. Results The study sample (N = 1,329) had a mean age of 85.2 years, were 72.8% female and the majority resided in long-term care (78.5%). Overall, 36.4% of individuals died within 360 days of surgery. After controlling for age, sex, medical comorbidity and medical conditions correlated with ADL impairment, addition of ADL measures improved the logistic regression model for predicting 360 day mortality (AIC = 1706.9 vs. 1695.0; c -statistic = 0.65 vs 0.67; difference in - 2 log likelihood ratios: χ2 = 16.9, p = 0.002). Conclusions Direct measures of ADL impairment provides additional prognostic information on mortality for older adults with hip fractures even after controlling for medical comorbidity. Observational studies using administrative databases without measures of ADLs may be potentially prone to confounding and bias and case-mix adjustment for hip fracture outcomes should include ADL measures where these are available.

The health-related quality of life (HRQoL) of the elderly population of Yi ethnic minority, which is the seventh largest nationality in China, has been rarely reported. This study was designed to explore the HRQoL of the elderly Yi ethnicity and association between their HRQOL and functional abilities. A total of 291 Yi ethnic residents were randomly recruited from 12 rural counties in Yunnan province and divided into different age groups. Local residents in Yunnan province and the elderly from Hangzhou were enrolled as controls. The MOS 36-Item Short Form Health Survey (SF-36), activities of daily living (ADL), instrumental activities of daily living (IADL) scales were utilized to evaluate the HRQoL and functional ability. One-way ANOVA was used to statistically compare the ADL and IADL among different age groups. The influential variables on HRQOL were analyzed by multiple linear regression analysis. Pearson correlation analysis was used to analyze the association among HRQoL, ADL and IADL. The HRQoL of the elderly Yi minority was significantly lower than those of local residents in Yunnan province and the elderly counterparts in Hangzhou. The IADL ability of the elderly Yi minority was low, whereas they could perform most items of ADL. ADL, IADL, and education level were positively associated with HRQoL, whereas age, chronic diseases, and the frequency of medication use were negatively correlated with HRQoL. The HRQoL and functional capacity of the elderly Yi ethnic minority were lower compared with their counterparts in Yunnan province and Hangzhou. The low level of IADL indicated that the elderly Yi participants had a high risk of cognitive impairment. Much attention should be diverted to influential factors of the HRQoL.

Humans differ from other animals in the way they can skilfully and precisely operate or invent tools to facilitate their everyday life. Tools have dominated our home, travel and work environment, becoming an integral step for our motor skills development. What happens when the part of the brain responsible for tool use is damaged in our adult life due to a cerebrovascular accident? How does daily life change when we lose the previously mastered ability to make use of the objects around us? How do patients suffering from compromised tool use cope with food preparation, personal hygiene, grooming, housework, or use of home appliances? In this literature review we present a state of the art for single and multiple tool use research, with a focus on the impact that apraxia (impaired ability to perform tool-based actions) and action disorganization syndrome (ADS; impaired ability to carry out multi-step actions) have on activities of daily living (ADL). Firstly, we summarize the behavioral studies investigating the impact of apraxia and other comorbidity syndromes, such as neglect or visual extinction, on ADL. We discuss the hallmarks of the compromised tool use in terms of the sequencing of action steps, conceptual errors committed, spatial motor control, and temporal organization of the movement. In addition, we present an up-to-date overview of the neuroimaging and lesion analyses studies that provide an insight into neural correlates of tool use in the human brain and functional changes in the neural organization following a stroke, in the context of ADL. Finally we discuss the current practice in neurorehabilitation of ADL in apraxia and ADS aiming at increasing patients' independence.

AeroADL: applying the integration of the Suomi-NPP science algorithms with the Algorithm Development Library to the calibration and validation task

A common problem for the off-line validation of the calibration algorithms and algorithm coefficients is being able to run science data through the exact same software used for on-line calibration of that data. The Joint Polar Satellite System (JPSS) program solved part of this problem by making the Algorithm Development Library (ADL) available, which allows the operational algorithm code to be compiled and run on a desktop Linux workstation using flat file input and output. However, this solved only part of the problem, as the toolkit and methods to initiate the processing of data through the algorithms were geared specifically toward the algorithm developer, not the calibration analyst. In algorithm development mode, a limited number of sets of test data are staged for the algorithm once, and then run through the algorithm over and over as the software is developed and debugged. In calibration analyst mode, we are continually running new data sets through the algorithm, which requires significant effort to stage each of those data sets for the algorithm without additional tools. AeroADL solves this second problem by providing a set of scripts that wrap the ADL tools, providing both efficient means to stage and process an input data set, to override static calibration coefficient look-up-tables (LUT) with experimental versions of those tables, and to manage a library containing multiple versions of each of the static LUT files in such a way that the correct set of LUTs required for each algorithm are automatically provided to the algorithm without analyst effort. Using AeroADL, The Aerospace Corporation's analyst team has demonstrated the ability to quickly and efficiently perform analysis tasks for both the VIIRS and OMPS sensors with minimal training on the software tools.

Functional competency and cognitive ability in mild Alzheimer's disease: relationship between ADL assessed by a relative/ carer-rated scale and neuropsychological performance.

PubMed

Matsuda, Osamu; Saito, Masahiko

2005-06-01

Alzheimer's disease (AD) is characterized by multiple cognitive deficits and affects functional competency to perform daily activities (ADL). As this may contribute to the patient's overall disability, it is important to identify factors that compromise competency. The relationship between different cognitive domains and functional activities in AD was studied. The functional competency of 73 Japanese AD patients, most with mild dementia, was assessed using a 27-item relative/carer-rating scale covering 7 ADL: managing finances, using transportation, taking precautions, self-care, housekeeping, communication and taking medicine. Cognitive assessment used 16 neuropsychological tests from the Japanese version of the WAIS-R and COGNISTAT, covering 9 cognitive domains: orientation, attention, episodic memory, semantic memory, language, visuoperceptual and construction abilities, computational ability, abstract thinking, and psychomotor speed. Multiple regression analysis by the stepwise method indicated that functional competency could, for the most part, be predicted from test scores for orientation, abstract thinking and psychomotor speed. The results of this study suggest that impairment of these three cognitive domains plays an important role in the functional deterioration of AD.

Few studies have examined instrumental activities of daily living (iADLs) in nondemented Parkinson's disease (PD), and the majority of these studies have used report-based measures, which can have limited validity. The present study had two main goals: (a) to examine the performance of nondemented PD patients on two performance-based measures of iADLs, which are considered more objective functional measures, and (b) to examine the cognitive, motor, and psychiatric correlates of iADL impairment in PD. Ninety-eight nondemented PD patients and 47 healthy older adults were administered performance-based measures that assess the ability to manage medications (Medication Management Ability Assessment) and finances (University of California, San Diego, UCSD, Performance-based Skills Assessment), the Mattis Dementia Rating Scale to assess global cognitive functioning, the Unified Parkinson's Disease Rating Scale Part III to assess motor symptom severity, and the Geriatric Depression Scale to assess depressive symptoms. Nondemented PD patients demonstrated significantly impaired scores relative to the healthy comparison group on the performance-based measure of financial management, but there were no significant group differences in medication management. Global cognitive functioning, motor severity, and depressive symptoms did not correlate with scores on either of the functional measures, except for a small correlation between depressive symptoms and financial management. The two performance-based measures of iADL functioning did not correlate with one another. These findings suggest that medication and financial management may not be predicted based on global cognitive functioning and that iADLs may not be represented by a single construct. Furthermore, these findings suggest the potential need for a multidimensional approach to assessing iADLs.

ADL is a formal language to express archetypes, independent of standards or domain. However, its specification is not precise enough in relation to the specialization and semantic of archetypes, presenting difficulties in implementation and a few available tools. Archetypes may be implemented using other languages such as XML or OWL, increasing integration with Semantic Web tools. Exchanging and transforming data can be better implemented with semantics oriented models, for example using OWL which is a language to define and instantiate Web ontologies defined by W3C. OWL permits defining significant, detailed, precise and consistent distinctions among classes, properties and relations by the user, ensuring the consistency of knowledge than using ADL techniques. This paper presents a process of an openEHR ADL archetypes representation in OWL ontologies. This process consists of ADL archetypes conversion in OWL ontologies and validation of OWL resultant ontologies using the mutation test.

Cognitive functioning influences activities of daily living (ADL). However, studies reporting the association between ADL and neuropsychological performance show inconsistent results regarding what specific cognitive domains are related to each specific functional domains. Additionally, whether depressive symptoms are associated with a worse functional performance in older adults is still under explored. We investigated if specific cognitive domains and depressive symptoms would affect different aspects of ADL. Participants were 274 older adults (96 normal aging participants, 85 patients with mild cognitive impairment, and 93 patients probable with mild Alzheimer’s disease dementia) with low formal education (∼4 years). Measures of ADL included three complexity levels: Self-care, Instrumental-Domestic, and Instrumental-Complex. The specific cognitive functions were evaluated through a factorial strategy resulting in four cognitive domains: Executive Functions, Language/Semantic Memory, Episodic Memory, and Visuospatial Abilities. The Geriatric Depression Scale measured depressive symptoms. Multiple linear regression analysis showed executive functions and episodic memory as significant predictors of Instrumental-Domestic ADL, and executive functions, episodic memory and language/semantic memory as predictors of Instrumental-Complex ADL (22 and 28% of explained variance, respectively). Ordinal regression analysis showed the influence of specific cognitive functions and depressive symptoms on each one of the instrumental ADL. We observed a heterogeneous pattern of association with explained variance ranging from 22 to 38%. Different instrumental ADL had specific cognitive predictors and depressive symptoms were predictive of ADL involving social contact. Our results suggest a specific pattern of influence depending on the specific instrumental daily living activity. PMID:26257644

Older adult’s ability to self-manage illness is dependent on their ability to perform activities of daily living (ADL). Forty-five percent of those older than 65 years will have ongoing clinical needs after hospital discharge and require post-acute care (PAC) services in settings such as home health care (HHC) and skilled nursing facilities (SNF). The Improving Medicare Post-Acute Care Transformation Act (IMPACT) of 2014 requires PAC providers to begin collecting and reporting ADL data to build a coordinated approach to payment and standardize patient assessments and quality measurement. The aim of this integrative review was to compare the methods of assessing ADLs in HHC to SNF. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement was used to ensure results were reported systematically. A scientific literature search without date restriction within the PubMed and Cumulative Index of Nursing and Allied Health Literature (CINAHL) databases was conducted. Two independent investigators assessed study quality using the quality appraisal instrument developed by Kmet and colleagues. Study quality ranged from 94.5% to 100%. Of the 18749 articles identified by the search, eight met inclusion criteria and four tools were identified that are used to assess ADLs in SNF and HHC. Although SNF and HHC collect similar ADL information, the range of content covered, item definitions, scoring, and psychometrics are not comparable across settings. PMID:28471793

Cognitively-Related Basic Activities of Daily Living Impairment Greatly Increases the Risk of Death in Alzheimers Disease.

Some Alzheimer's disease (AD) patients die without ever developing cognitively impaired basic activities of daily living (basic ADL), which may reflect slower disease progression or better compensatory mechanisms. Although impaired basic ADL is related to disease severity, it may exert an independent risk for death. This study examined the association between impaired basic ADL and survival of AD patients, and proposed a multistate approach for modeling the time to death for patients who demonstrate different patterns of progression of AD that do or do not include basic ADL impairment. 1029 patients with probable AD at the Baylor College of Medicine Alzheimer's Disease and Memory Disorders Center met the criteria for this study. Two complementary definitions were used to define development of basic ADL impairment using the Physical Self-Maintenance Scale score. A weighted Cox regression model, including a time-dependent covariate (development of basic ADL impairment), and a multistate survival model were applied to examine the effect of basic ADL impairment on survival. As expected decreased ability to perform basic ADL at baseline, age at initial visit, years of education, and sex were all associated with significantly higher mortality risk. In those unimpaired at baseline, the development of basic ADL impairment was also associated with a much greater risk of death (hazard ratios 1.77-4.06) over and above the risk conferred by loss of MMSE points. A multi-state Cox model, controlling for those other variables quantified the substantive increase in hazard ratios for death conferred by the development of basic ADL impairment by two definitions and can be applied to calculate the short term risk of mortality in individual patients. The current study demonstrates that the presence of basic ADL impairment or the development of such impairments are important predictors of death in AD patients, regardless of severity.

The potential subjects were 4,472 individuals aged 65 years and older who voluntarily participated in a large cohort study, the Fujiwara-kyo study. We used self-administered questionnaires consisting of an activities of daily living (ADL) questionnaire with the Physical Fitness Test established by the Ministry of Education, Culture, Sports, Science and Technology (12 ADL items) to determine the index of higher-level physical independence, demographics, Geriatric Depression Scale, and so on. Mini-mental state examination, measurement of physical fitness, and blood tests were also carried out. A lower ADL level was defined as having a total score of the 12 ADL items (range, 12-36 points) that was below the first quartile of a total score for all the subjects. Factors associated with a low ADL level were examined by multiple logistic regression. A total of 4,198 remained as subjects for analysis. The male, female and 5-year-old groups showed significant differences in the median score of 12 ADL items between any two groups. The highest odds ratio among factors associated with lower ADL level by multiple logistic regression with mutually adjusted independent variables was 4.49 (95%CI: 2.82-7.17) in the groups of "very sharp pain" or "strong pain" during the last month. Low physical ability, self-awareness of limb weakness, a BMI of over 25, low physical activity, cerebrovascular disorder, depression, low cognitive function, unable "to see normally", unable "to hear someone", "muscle, bone and joint pain" were independently associated with lower ADL level. Multiple factors are associated with lower ADL level assessed on the basis of the 12 ADL items.

Whether limitation in ability to perform activities of daily living (ADL) or gait speed can identify elders in whom the association of systolic (SBP) and diastolic (DBP) blood pressure with cardiovascular events (CVD) and death differs is unclear. We evaluated whether limitation in ADL or gait speed modify the association of SBP or DBP with incident CVD (N= 2,358) and death (N=3,547) in the Cardiovascular Health Study. Mean age was 78 ± 5 and 21% reported limitation in ≥1 ADL. There were 778 CV events and 1,289 deaths over 9 years. Among persons without and with ADL limitation, SBP was associated with incident CVD: HR (per 10 mmHg increase) 1.08 (95% CI 1.03, 1.13) and 1.06 (0.97, 1.17), respectively. ADL modified the association of DBP with incident CVD. Among those without ADL limitation, DBP was weakly associated with incident CVD, HR 1.04 (0.79, 1.37) for DBP > 80, compared with <65 mmHg. Among those with ADL limitation, DBP was inversely associated with CVD: HR 0.65 (0.44, 0.96) for DBP 66–80 mmHg and HR 0.49 (0.25, 0.94) for DBP > 80, compared to DBP ≤ 65. Among persons with ADL limitation, a DBP 66–80 had the lowest risk for death, HR 0.72 (0.57, 0.91), compared with DBP ≤ 65. Associations did not vary by 15 feet walking speed ADL can identify elders in whom diastolic hypotension is associated with higher CV risk and death. Functional status, rather than chronologic age alone, should inform design of hypertension trials in elders. PMID:24935945

[Purpose] The purpose of the current study was to clarify problems associated with swallowing, related to nutrition and activities of daily living (ADL), in elderly individuals with sarcopenia. [Subjects and Methods] Seventy-seven subjects were assigned to a sarcopenia or a non-sarcopenia group according to a definition used by the European Working Group on Sarcopenia in Older People. Analyses were conducted including and excluding subjects with a central nervous system disorders in order to focus on the influence of sarcopenia. The swallowing ability, ADL, and nutrition levels were compared between the 2 groups. [Results] Swallowing function as well as ADL and nutrition levels were significantly lower in the sarcopenia group than in the non-sarcopenia group. [Conclusion] It is important to include dimensions of swallowing, nutrition, and ADL in the assessment and treatment of swallowing problems in elderly individuals with sarcopenia. PMID:25729176

Geriatric Intermediate Care Facilities (GICF) have been established to help the hospitalized elderly return home. Users of the GICF are elderly persons who do not need hospitalization, but are mentally or physically impaired. To determine what factors influence users' destinations upon discharge from GICF, we analyzed various characteristics such as age, sex, place of residence before admission, length of stay, intellectual impairment, ability to perform activities of daily living (ADL) among users (N = 389) in a GICF in Chiba City. Multiple logistic regression analyses revealed that, compared with the users who were hospitalized, users who were male, admitted for home, stayed for long periods, and had a high ability to perform ADL were more likely to return home. The analyses also revealed that, compared with the users who were institutionalized, users who came from home, stayed for short periods, and had a high ability to perform ADL were more likely to return home. Evaluating a user's physical, mental, and socioeconomical conditions at an early stage of admission to a GICF may allow us to predict whether the user can be successfully discharged to his or her home or will have to remain at the GICF for an extended period.

Background/Aims Optimal bowel preparation is essential for successful screening or for surveillance colonoscopy (SC). Inadequate bowel preparation is associated with older age, the male gender, and the presence of certain comorbidities. However, the association between patients’ functional status and bowel preparation quality has not been studied. We prospectively examined the relationship between functional status, namely, the ability to perform activities of daily living (ADLs) and ambulate, and the quality of bowel preparation in elderly patients undergoing SC. Methods Before undergoing SC, 88 elderly patients were surveyed regarding their functional status, specifically regarding their ability to perform ADLs and ambulate a quarter of a mile. Gastroenterologists then determined the quality of the bowel preparation, which was classified as either adequate or inadequate. Then, the frequency of inadequate bowel preparation in patients who did or did not experience difficulty performing ADLs and ambulating was calculated. Results Difficulty ambulating (unadjusted odds ratio [OR], 4.83; p<0.001), difficulty performing ADLs (OR, 2.93; p=0.001), and history of diabetes (OR, 2.88; p=0.007) were significant univariate predictors of inadequate bowel preparation. After adjusting for the above variables, only difficulty ambulating (adjusted OR, 5.78; p=0.004) was an independent predictor of inadequate bowel preparation. Conclusions Difficulty with ambulation is a strong predictor of inadequate bowel preparation in elderly patients undergoing SC. PMID:27021501

Cognitive Rehabilitation for Alzheimer's disease (AD) is an integrative multimodal intervention. It aims to maintain autonomy and quality of life by enhancing the patients' abilities to compensate for decreased cognitive functioning. We evaluated the feasibility of a group-based Cognitive Rehabilitation approach in mild AD dementia and assessed its effect on activities of daily living (ADL). We included 16 patients with AD dementia in a controlled partial-randomized design. We adapted the manual-guided Cognitive Rehabilitation program (CORDIAL) to a group setting. Over the course of three months, one group received the Cognitive Rehabilitation intervention (n = 8), while the other group received a standardized Cognitive Training as an active control condition (n = 8). ADL-competence was measured as primary outcome. The secondary outcome parameters included cognitive abilities related to daily living, functional cognitive state, and non-cognitive domains, e.g., quality of life. For each scale, we assessed the interaction effect 'intervention by time', i.e., from pre-to post-intervention. We found no significant interaction effect of intervention by time on the primary outcome ADL-competence. The interaction effect was significant for quality of life (Cohen's d: -1.43), showing an increase in the intervention group compared with the control group. Our study demonstrates the feasibility of a group-based Cognitive Rehabilitation program for patients with mild AD dementia. The Cognitive Rehabilitation showed no significant effect on ADL, possibly reflecting a lack of transfer between the therapy setting and real life. However, the group setting enhanced communication skills and coping mechanisms. Effects on ADL may not have reached statistical significance due to a limited sample size. Furthermore, future studies might use an extended duration of the intervention and integrate caregivers to a greater extent to increase transfer to activities of daily living.

Older African Americans consistently report diminished capacities to perform activities of daily living (ADL) compared with other racial groups. The extent to which bodily pain is related to declining abilities to perform ADL/ADL disability in African Americans remains unclear, as does whether this relationship exists to the same degree in African American men and women. For nurses to provide optimal care for older African Americans, a better understanding of the relationship between bodily pain and ADL disability and how it may differ by sex is needed. The aim of this study was to examine whether pain, age, education, income, marital status and/or comorbid conditions were associated with ADL disabilities in older African American women and men. This was a cross-sectional descriptive study. The sample included 598 participants (446 women, 152 men) from the first wave of the Baltimore Study on Black Aging. African American women (odds ratio [OR] = 4.06; 95% confidence interval [CI] 2.63-6.26) and African American men (OR = 6.44; 95% CI = 2.84-14.57) who reported bodily pain had greater ADL disability than those who did not report bodily pain. Having two or more comorbid conditions also was significantly associated with ADL disability in African American women (OR = 3.95; 95% CI: 2.09-7.47). Further work is needed to understand pain differences between older African American women and men to develop interventions that can be tailored to meet the individual pain needs of both groups.

Observing the onset of disability in older adults.

One of the greatest threats to the ability of older adults to live independently is the onset of disability in activities adults perform in their daily lives, such as dressing, eating, toileting, managing one's money, preparing meals and so on. This article examines the onset of disability in older adult Americans using three waves of the Asset and Health Dynamics Among the Oldest Old (AHEAD) survey (1993, 1995, 1998; n=4228). We use medical/demographic factors (arthritis, heart disease, diabetes; age, gender, race/ethnicity, wealth), baseline characteristics (affect, cognition, health behaviors, medical insurance), and time-varying covariates (changes in chronic conditions and baseline characteristics) to predict the onset of activities of daily living (ADLs) and instrumental activities of daily living (IADLs) disability, individually and in the aggregate, over time. We find the onset of ADL and IADL disability is a complex process, suggesting important roles for medical, demographic, social, psychological, and behavioral triggers, specifically negative affect, higher body weight, and by the lack of vigorous exercise. We also find that individual ADL and IADL impairments are predicted by a variety of different factors, suggesting that summary measures of disability may be masking a wealth of potentially useful interventions. In general, public health efforts in the area of controlling obesity and treating depressive symptoms should be supported.

Mild cognitive impairment (MCI) is characterized by a decrease in cognitive abilities that does not affect the ability to perform activities of daily living (ADLs). Therefore, this condition is easily overlooked. The prevalence and factors of influence for MCI in older people living in publicly managed congregate housing are currently unknown. This study investigated the prevalence and distribution of MCI in older people living in publicly managed congregate housing and assessed the correlations among quality of life (QoL), ADL, and MCI. This study applied a correlational study design. The participants were older people who met the study criteria and who lived in public housing in Wanhua District, Taipei City, Taiwan. One-on-one interviews were conducted to measure the cognitive abilities of the participants, and 299 valid samples were collected. The prevalence of MCI in older people living in publicly managed congregate housing was 16.1%. The χ test was employed to evaluate the distribution of MCI prevalence and indicated that the group with higher MCI prevalence exhibited the following characteristics: older than 81 years; married; lived in public housing for more than 20 years; cohabiting; had a history of drinking; and exhibited severe memory regression, physical disabilities, psychological distress, and low QoL. The difference between the groups achieved statistical significance (p < .05). After performing logistical regression analysis to control demographic variables, we found that QoL and ADL were critical for predicting MCI. This study confirmed that QoL and ADL correlate significantly with MCI in older people. Maintaining an open and supportive community enables older people to maintain sufficient mental activity, which has been shown to reduce MCI. These findings may provide an important reference for policy makers, educators, researchers, and community practitioners in their development of service strategies for older people.

This study aimed to assess the association between risk of malnutrition and 7-year mortality, controlling for functional ability, socio-demographics, lifestyle behavior and diseases, and investigate the interaction between risk of malnutrition and functional ability on the risk of mortality. A longitudinal study on home-living and special-housing residents aged ⩾ 60 years was conducted. Of 2312 randomly invited participants, 1402 responded and 1203 provided information on both nutritional status and functional ability. The risk of malnutrition was estimated by the occurrence of at least one anthropometric measure (BMI, MAC and CC) below cut-off in addition to the presence of at least one subjective measure (decreased food intake, weight loss and eating difficulty). At baseline, 8.6% of subjects were at risk of malnutrition and during the 7-year follow-up 34.6% subjects died. The risk of malnutrition was independently associated with 7-year mortality (hazard ratio (HR) 1.84, 95% confidence interval (CI) 1.28-2.65). Additional independent predictors were dementia (HR 2.76, 95% CI 1.85-4.10), activity of daily living (ADL) dependence (HR 2.08, 95% CI 1.62-2.67), heart disease (HR 1.44, 95% CI 1.16-1.78), diabetes (HR 1.41, 95% CI 1.03-1.93) and older age (HR 1.09, 95% CI 1.07-1.10). Moreover, the risk of malnutrition and ADL dependence in combination predicted the poorest survival rate (18.7%, P<0.001). The risk of malnutrition significantly increases the risk of mortality in older people. Moreover, risk of malnutrition and ADL dependence together explain a significantly poorer survival rate; however, the importance of this interaction decreased in the multivariable model and risk of malnutrition and ADL dependence independently explained a significant risk of mortality.

To describe a standardized observation protocol to determine if nursing home (NH) staff offer choice to residents during 3 morning activities of daily living (ADL) and compare the observational data with deficiency statements cited by state survey staff. Morning ADL care was observed in 20 NHs in 5 states by research staff using a standardized observation protocol. The number of observations in which choice was not offered was documented for 3 morning ADL care activities and compared with deficiency statements made by surveyors. Staff failed to offer choice during morning ADL care delivery for at least 1 of 3 ADL care activities in all 20 NHs. Observational data showed residents were not offered choice about when to get out of bed (11%), what to wear (25%), and breakfast dining location (39%). In comparison, survey staff issued only 2 deficiencies in all 20 NHs relevant to choice in the targeted ADL care activities, and neither deficiency was based on observational data. Survey interpretative guidelines instruct surveyors to observe if residents are offered choice during daily care provision, but standardized observation protocols are not provided to surveyors to make this determination. The use of a standardized observation protocol in the survey process similar to that used by research staff in this study would improve the accuracy and transparency of the survey process.

To identify interventions that aim to reduce dependency in activities of daily living (ADL) in homecare service users. To determine: content; effectiveness in improving ability to perform ADL; and whether delivery by qualified occupational therapists influences effectiveness. The Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE, AMED, CINAHL, PsycINFO, OTseeker, PEDro, Web of Science, CIRRIE, and ASSIA. We included: randomised controlled trials, non-randomised controlled trials and controlled before and after studies. Two reviewers independently screened studies for inclusion, assessed risk of bias and extracted data. A narrative synthesis of the findings was conducted. Thirteen studies were included, totalling 4975 participants. Ten (77%) were judged to have risk of bias. Interventions were categorised as those termed 're-ablement' or 'restorative homecare' (n=5/13); and those involving separate components which were not described using this terminology (n=8/13). Content of the intervention and level of health professional input varied within and between studies. Effectiveness on ADL: eight studies included an ADL outcome, five favoured the intervention group, only two with statistical significance, both these were controlled before and after studies judged at high risk of bias. ADL outcome was reported using seven different measures. Occupational therapy: there was insufficient evidence to determine whether involvement of qualified occupational therapists influenced effectiveness. There is limited evidence that interventions targeted at personal ADL can reduce homecare service users' dependency with activities, the content of evaluated interventions varies greatly. © The Author(s) 2015.

This investigation examined the demographic characteristics along with 3 measures of motor function in determining outcomes in activities of daily living (ADL) after distributed constraint-induced therapy (dCIT). The study recruited 69 stroke patients who received 3 weeks of dCIT for 2 hours daily, 5 days a week. The self-reported outcome measures for daily function were the Motor Activity Log (MAL) including the amount of use (AOU) and quality of movement (QOM), Nottingham Extended Activities of Daily Living Questionnaire (NEADL), and the Stroke Impact Scale (SIS). Age, sex, onset, side of stroke, Fugl-Meyer assessment (FMA), Wolf Motor Function Test (WMFT), and Action Research Arm Test (ARAT) were the potential predictors. The ARAT grasp-grip-pinch score was the most dominant predictor for MAL-AOU and NEADL (P< 0.05), and the ARAT total score for the subscore of the ADL/instrumental ADL section of the SIS (P< 0.05). The FMA wrist-hand score was a significant predictor for MAL-QOM (P< 0.05). Age was the only demographic factor that significantly predicted NEADL performance (P< 0.05). Among the 3 commonly used measures of motor function after stroke, ARAT was the strongest determinant in predicting MAL-AOU, MAL-QOM, and SIS-ADL/instrumental ADL after dCIT.

To describe levels of attention deficits among people with stroke living in the community and explore relationships between attention, balance, function and falls. Forty-eight mobile community-dwelling people with stroke (30 men, 18 women, mean age 68.4 +/- 11.2) were recruited to this cross-sectional investigation through General Practitioners. Twenty-six participants had a right, 21 a left hemisphere infarction and one had a brain stem lesion; mean time since stroke was 46 months (range five to 204). Participants' were interviewed about fall-events; attention, balance and function were assessed using standardised tests. Visual inattention was identified in five participants (10%), deficits of sustained attention in 15 (31%), auditory selective attention in nine (19%), visual selective attention in 17 (35%) and divided attention deficits in 21 participants (43%). Sustained and divided attention scores correlated with balance, ADL ability and fall-status (p < 0.01). The balance and function of subjects with normal attention were better than those with abnormal scores (p < 0.01). Analysis of variance revealed differences between repeat-fallers and non-fallers with no near-falls for divided attention, balance and ADL ability (p < 0.01). Attention deficits were common among this sample; sustained and divided attention deficits correlated with functional impairments and falls, highlighting that attention deficits might contribute to accident prone behaviour and falling.

Visual and visuospatial dysfunction is prevalent in Parkinson's disease (PD). To promote assessment of these often overlooked symptoms, we adapted the PD Vision Questionnaire for Internet administration. The questionnaire evaluates visual and visuospatial symptoms, impairments in activities of daily living (ADLs), and motor symptoms. PD participants of mild to moderate motor severity (n = 24) and healthy control participants (HC, n = 23) completed the questionnaire in paper and web-based formats. Reliability was assessed by comparing responses across formats. Construct validity was evaluated by reference to performance on measures of vision, visuospatial cognition, ADLs, and motor symptoms. The web-based format showed excellent reliability with respect to the paper format for both groups (all P′s < 0.001; HC completing the visual and visuospatial section only). Demonstrating the construct validity of the web-based questionnaire, self-rated ADL and visual and visuospatial functioning were significantly associated with performance on objective measures of these abilities (all P′s < 0.01). The findings indicate that web-based administration may be a reliable and valid method of assessing visual and visuospatial and ADL functioning in PD. PMID:22530162

This paper seeks to document the progression of disability in a developing country and to examine gender differences in this process. The data come from the Mexican Health and Aging Study (MHAS), a nationally representative sample of older adults. An ordinal logistic regression (n = 3283) is used to measure the progression of disability that considers: (1) no disability, (2) mobility problems, (3) mobility problems with IADLs limitations, (4) mobility problems with ADLs limitations, (5) combinations of the latter three and (6) death. Approximately 43% of the sample remained in the same level of disability after 2 years. The patterns of progression with two disabilities differ for men and women. Our model reflects the importance of separating ADLs and IADLs in the study of disability progression in Mexico. Varying risk profiles and cultural differences might influence the divergent disability paths followed by each gender. Implications for Rehabilitation The disablement process involving transitions from mobility impairments to IADL and ADL limitations seen in developed countries differs for older adults in Mexico. Cultural differences may influence the progression from non-disabled to becoming disabled in different ways for females in developing countries like Mexico. One-fifth of individuals showed greater function and independence over time, suggesting that the disablement process is reversible. This finding highlights the need to focus on improving mobility, ADL, and IADL skills to facilitate successful aging. Although disability is often conceptualised as a combination of ADL and IADL limitations, gender differences seen in Mexico indicate the need to separate ADL and IADL when developing approaches to prevent or ameliorate disability.

To evaluate the ability of COPD patients to perform activities of daily living (ADL); to identify barriers that prevent these individuals from performing ADL; and to correlate those barriers with dyspnea severity, six-minute walk test (6MWT), and an ADL limitation score. In COPD patients and healthy, age-matched controls, the number of steps, the distance walked, and walking time were recorded with a triaxial accelerometer, for seven consecutive days. A questionnaire regarding perceived barriers and the London Chest Activity of Daily Living (LCADL) scale were used in order to identify the factors that prevent the performance of ADL. The severity of dyspnea was assessed with two scales, whereas submaximal exercise capacity was determined on the basis of the 6MWT. We evaluated 40 COPD patients and 40 controls. In comparison with the control values, the mean walk time was significantly shorter for COPD patients (68.5 ± 25.8 min/day vs. 105.2 ± 49.4 min/day; p < 0.001), as was the distance walked (3.9 ± 1.9 km/day vs. 6.4 ± 3.2 km/day; p < 0.001). The COPD patients also walked fewer steps/day. The most common self-reported barriers to performing ADL were lack of infrastructure, social influences, and lack of willpower. The 6MWT distance correlated with the results obtained with the accelerometer but not with the LCADL scale results. Patients with COPD are less active than are healthy adults of a comparable age. Physical inactivity and the barriers to performing ADL have immediate implications for clinical practice, calling for early intervention measures.

The Foot and Ankle Ability Measure (FAAM) is a region-specific, non-disease-specific outcome instrument that possesses many of the clinimetric qualities recommended for an outcome instrument. Evidence of validity to support the use of the FAAM is available in individuals with a wide array of ankle and foot disorders. However, additional evidence to support the use of the FAAM for those with chronic ankle instability (CAI) is needed. To provide evidence of construct validity for the FAAM based on hypothesis testing in athletes with CAI. Between-groups comparison. Athletic training room. Thirty National Collegiate Athletic Association Division II athletes (16 men, 14 women) from one university. The FAAM including activities of daily living (ADL) and sports subscales and the global and categorical ratings of function. For both the ADL and sports subscales, FAAM scores were greater in healthy participants (100 +/- 0.0 and 99 +/- 3.5, respectively) than in subjects with CAI (88 +/- 7.7 and 76 +/- 12.7, respectively; P < .001). Similarly, for both ADL and sports subscales, FAAM scores were greater in athletes who indicated that their ankles were normal (98 +/- 6.3 and 96 +/- 6.9, respectively) than in those who classified their ankles as either nearly normal or abnormal (87 +/- 6.6 and 71 +/- 11.1, respectively; P < .001). We found relationships between FAAM scores and self-reported global ratings of function for both ADL and sports subscales. Relationships were stronger when all athletes, rather than just those with CAI, were included in the analyses. The FAAM may be used to detect self-reported functional deficits related to CAI.

To investigate the effect of a medical food (Souvenaid) on body mass index (BMI) and functional abilities in patients with mild Alzheimer's disease (AD). DESIGN/SETTING/PARTICIPANTS/INTERVENTION /MEASUREMENTS: These analyses were performed on data from a 12-week, double-blind, randomized, controlled, multicenter, proof-of-concept study with a similarly designed and exploratory 12-week extension period. Patients with mild AD (Mini-Mental State Examination score of 20-26) were randomized to receive either the active product or an iso-caloric control product. While primary outcomes included measures of cognition, the 23-item Alzheimer's Disease Cooperative Study-Activities of Daily Living (ADCS-ADL) scale was included as a secondary outcome. Both ADCS-ADL and BMI were assessed at baseline and Weeks 6, 12 and 24. Data were analyzed using a repeated-measures mixed model. Overall, data suggested an increased BMI in the active versus the control group at Week 24 (ITT: p = 0.07; PP: p = 0.03), but no treatment effect on ADCS-ADL was observed. However, baseline BMI was found to be a significant treatment effect modifier (ITT: p = 0.04; PP: p = 0.05), and an increase in ADCS-ADL was observed at Week 12 in patients with a 'low' baseline BMI (ITT: p = 0.02; PP: p = 0.04). These data indicate that baseline BMI significantly impacts the effect of Souvenaid on functional abilities. In addition, there was a suggestion that Souvenaid increased BMI.

To determine the factors that influence users' destinations on discharge from Geriatric Intermediate Care Facilities (GICFs), which were established in Japan in 1987 to help hospitalized older people return home. Retrospective chart review. A 94-bed GICF attached to Saku Central Hospital in Japan. Charts of all users (N = 437) aged 65 years and older, discharged from the GICF between July 1987 and February 1991, were reviewed. The independent variables, obtained from users' admission records, were age, sex, place of residence before admission, length of stay, intellectual impairment (assessed by Karasawa's diagnostic criteria for senile dementia), ability to perform activities of daily living (ADLs), and living arrangement of users in the GICF. The dependent variable was destination after discharge from the GICF. Multiple logistic regression analyses revealed that, compared with users who were able to successfully return home, users with little ability to perform ADLs, male users, and those admitted from other institutions were more likely to be hospitalized. Such analyses also revealed that users who came from institutions, had low ability to perform ADLs, and lived alone were more likely to be institutionalized in nursing homes. Evaluating a user's physical, mental, and socioeconomic conditions at an early stage of admission to a GICF may allow us to predict whether the user can be successfully discharged to his or her home or will have to remain in the GICF for an extended period.

We investigated the effects of different intensities of arm and leg rehabilitation training on the functional recovery of activities of daily living (ADL), walking ability, and dexterity of the paretic arm, in a single-blind randomised controlled trial. Within 14 days after stroke onset, 101 severely disabled patients with a primary middle-cerebral-artery stroke were randomly assigned to: a rehabilitation programme with emphasis on arm training; a rehabilitation programme with emphasis on leg training; or a control programme in which the arm and leg were immobilised with an inflatable pressure splint. Each treatment regimen was applied for 30 min, 5 days a week during the first 20 weeks after stroke. In addition, all patients underwent a basic rehabilitation programme. The main outcome measures were ability in ADL (Barthel index), walking ability (functional ambulation categories), and dexterity of the paretic arm (Action Research arm test) at 6, 12, 20, and 26 weeks. Analyses were by intention to treat. At week 20, the leg-training group (n=31) had higher scores than the control group (n=37) for ADL ability (median 19 [IQR 16-20] vs 16 [10-19], p<0.05), walking ability (4 [3-5] vs 3 [1-4], p<0.05), and dexterity (2 [0-56] vs 0 [0-2], p<0.01). The arm-training group (n=33) differed significantly from the control group only in dexterity (9 [0-39] vs 0 [0-2], p<0.01). There were no significant differences in these endpoints at 20 weeks between the arm-training and leg-training groups. Greater intensity of leg rehabilitation improves functional recovery and health-related functional status, whereas greater intensity of arm rehabilitation results in small improvements in dexterity, providing further evidence that exercise therapy primarily induces treatment effects on the abilities at which training is specifically aimed.

Electrogoniometer measurement and directional analysis of wrist angles and movements during the Sollerman hand function test.

Dauncey, Thomas; Singh, Harvinder P; Dias, Joseph J

Clinical measurement. To investigate the characteristics of wrist motion (area, axis, and location) during activities of daily living (ADL) using electrogoniometry. A sample of 83 normal volunteers performed the Sollerman hand function test (SHFT) with a flexible biaxial electrogoniometer applied to their wrists. This technique is accurate and reliable and has been used before for assessment of wrist circumduction in normal volunteers. A software package was used to overlay an ellipse of best fit around the 2-dimensional trace of the electrogoniometer mathematically computing the area, location, and axis angle of the ellipse. Most ADL could be completed within 20% of the total area of circumduction (3686°° ± 1575°°) of a normal wrist. An oblique plane in radial extension and ulnar flexion (dart-throwing motion plane) was used for rotation (-14° ± 32°) and power grip tasks (-29° ± 25°) during ADL; however, precision tasks (4° ± 28°), like writing, were performed more often in the flexion extension plane. In the dominant hand, only 2 power tasks were located in flexion region (cutting play dough [ulnar] and pouring carton [radial]), precision tasks were located centrally, and rotation and other power tasks were located in extension region. This study has identified that wrist motion during the ADL requires varying degrees of movement in oblique planes. Using electrogoniometry, we could visualize the area, location, and plane of motion during ADL. This could assist future researchers to compare procedures leading to loss of motion in specific quadrants of wrist motion and its impact on patient's ability in performing particular ADL. It could guide hand therapists to specifically focus on retraining the ADL that may be affected when wrist range of motion is lost after injury. Diagnostic level III.

Old adults' ability to execute activities of daily living (ADLs) declines with age. One possible reason for this decline is that the execution of customary motor tasks requires a substantially greater effort in old compared with young adults relative to their available maximal capacity. We tested the hypothesis that the relative effort (i.e., the percentage of joint moment relative to maximal joint moment) to execute ADLs is higher in old adults compared with young adults. Healthy young adults (n = 13; mean age, 22 years) and old adults (n = 14; mean age, 74 years) ascended and descended stairs and rose from a chair and performed maximal-effort isometric supine leg press. Using inverse dynamics analysis, we determined knee joint moments in ADLs and computed relative effort. Compared with young adults, old adults had 60% lower maximal leg press moments, 53% slower knee angular velocity at peak torque, and 27% lower knee joint moments in the ADLs (all p <.05). Relative effort in ascent was 54% (SD +/- 16%) and 78% (+/-20%) in young and old adults, respectively; in descent, it was 42% (+/-20%) and 88% (+/-43%); and in chair rise, it was 42% (+/-19%) and 80% (+/-34%) (all p <.05). The relative electromyographic activity of the vastus lateralis and the coactivity of the biceps femoris associated with this relative effort were, respectively, 2- and 1.6-fold greater in old compared with young adults in the 3 ADLs (p <.05). For healthy old adults, the difficulty that arises while performing ADLs may be due more to working at a higher level of effort relative to their maximum capability than to the absolute functional demands imposed by the task.

OBJECTIVE: To evaluate the ability of COPD patients to perform activities of daily living (ADL); to identify barriers that prevent these individuals from performing ADL; and to correlate those barriers with dyspnea severity, six-minute walk test (6MWT), and an ADL limitation score. METHODS: In COPD patients and healthy, age-matched controls, the number of steps, the distance walked, and walking time were recorded with a triaxial accelerometer, for seven consecutive days. A questionnaire regarding perceived barriers and the London Chest Activity of Daily Living (LCADL) scale were used in order to identify the factors that prevent the performance of ADL. The severity of dyspnea was assessed with two scales, whereas submaximal exercise capacity was determined on the basis of the 6MWT. RESULTS: We evaluated 40 COPD patients and 40 controls. In comparison with the control values, the mean walk time was significantly shorter for COPD patients (68.5 ± 25.8 min/day vs. 105.2 ± 49.4 min/day; p < 0.001), as was the distance walked (3.9 ± 1.9 km/day vs. 6.4 ± 3.2 km/day; p < 0.001). The COPD patients also walked fewer steps/day. The most common self-reported barriers to performing ADL were lack of infrastructure, social influences, and lack of willpower. The 6MWT distance correlated with the results obtained with the accelerometer but not with the LCADL scale results. CONCLUSIONS: Patients with COPD are less active than are healthy adults of a comparable age. Physical inactivity and the barriers to performing ADL have immediate implications for clinical practice, calling for early intervention measures. PMID:25410838

The study aims to (i) describe regional variation and gender differences in health status of older people (60 years and older) in Bangladesh, indicated by self-reported health problems and functional ability; (ii) explore influence of socio-economic factors on health status of older people. In a cross-sectional study in rural and urban Bangladesh, 696 older persons were asked about their health problems and ability to manage activities of daily living (ADL). More than 95% of older people reported health problems. Approximately 80% of elderly women in both the regions reported having four or more health problems compared with 42% and 63% elderly men in the urban and rural regions, respectively. More women (urban: 55%; rural: 36%) than men (urban: 32%; rural: 22%) also reported difficulties with ADL. Irrespective of age, sex and area of residence, those reporting greater number of health problems were more likely to report difficulty with at least one ADL task. Reporting pattern of specific health problems varied between urban and rural regions. Socio-economic indicators were found to have little influence on reporting of health problems, particularly in the rural region. Observed regional difference may be related to the influence of social and environmental factors, and level of awareness concerning certain health conditions.

A Process of Multidisciplinary Team Communication to Individualize Stroke Rehabilitation of an 84-Year-Old Stroke Patient.

Hiragami, Fukumi; Hiragami, Shogo; Suzuki, Yasuo

Previously, we have used a multidisciplinary team (MDT) approach to individualize rehabilitation of very old stroke patients as a means to establish intervention points for addressing impaired activities of daily living (ADL). However, this previous study was limited because of a lack in describing the communication process over time. This case study characterized the MDT communication process in the rehabilitation of an 84-year-old patient over the course of 15 weeks. The MDT consisted of 3 nurses, 1 doctor, 6 therapists, and the patient/families. Meetings (15 minutes each) were held at 4, 6, 8, and 15 weeks following the patient's admission. To individualize the rehabilitation, the communication process involved gaining knowledge about ADL impairments, sharing assessments, providing treatment options, and reflecting on desired treatment outcomes-a process termed KATR. The knowledge, assessment, treatment, and reflection (KATR) process established intervention points focusing on specific ADL impairments. The team members focused the interventions on the impaired ADL identified in the KATR process, and individualized rehabilitation was generated from the MDT information-sharing knowledge. In the initial meeting (Week 4), intervention points derived from the KATR process focused on rehabilitation of self-care impairments. These impairments improved by Week 15. By the last meeting, the MDT intervention points focused on mobility impairments. Having an organized communication process (i.e., KATR) facilitates individualization of rehabilitation without lengthy and frequent MDT meetings and enhances the quality of rehabilitation after a stroke.

Carcia, Christopher R; Martin, RobRoy L; Drouin, Joshua M

2008-01-01

Context: The Foot and Ankle Ability Measure (FAAM) is a region-specific, non–disease-specific outcome instrument that possesses many of the clinimetric qualities recommended for an outcome instrument. Evidence of validity to support the use of the FAAM is available in individuals with a wide array of ankle and foot disorders. However, additional evidence to support the use of the FAAM for those with chronic ankle instability (CAI) is needed. Objective: To provide evidence of construct validity for the FAAM based on hypothesis testing in athletes with CAI. Design: Between-groups comparison. Setting: Athletic training room. Patients or Other Participants: Thirty National Collegiate Athletic Association Division II athletes (16 men, 14 women) from one university. Main Outcome Measure(s): The FAAM including activities of daily living (ADL) and sports subscales and the global and categorical ratings of function. Results: For both the ADL and sports subscales, FAAM scores were greater in healthy participants (100 ± 0.0 and 99 ± 3.5, respectively) than in subjects with CAI (88 ± 7.7 and 76 ± 12.7, respectively; P < .001). Similarly, for both ADL and sports subscales, FAAM scores were greater in athletes who indicated that their ankles were normal (98 ± 6.3 and 96 ± 6.9, respectively) than in those who classified their ankles as either nearly normal or abnormal (87 ± 6.6 and 71 ± 11.1, respectively; P < .001). We found relationships between FAAM scores and self-reported global ratings of function for both ADL and sports subscales. Relationships were stronger when all athletes, rather than just those with CAI, were included in the analyses. Conclusions: The FAAM may be used to detect self-reported functional deficits related to CAI. PMID:18345343

Performing basic activities of daily living (ADLs) is one of the major difficulties encountered in dementia, which can have considerable negative impacts on the quality of life (QoL) of people with dementia (PwD). However, the extent to which basic ADL performance deteriorates across mild, moderate, and severe dementia is little examined and its impact, together with depression and neuropsychiatric behavior, upon QoL, is of considerable relevance across European countries. Data were drawn from people living in the community who were participants in a large-scale European study on transition from community living to care homes of PwD. PwD completed measures on cognitive functioning and QoL, and informal carers reported upon QoL, depressive symptomatology, psychopathology, and functional ability of the PwD. ADL performance deteriorated differently for each activity. In particular, toileting, transfer, and feeding remained relatively intact throughout, whereas performance on bathing and dressing deteriorated to a greater extent from mild to severe dementia. It appears that continence was not affected by the stage of dementia with similar levels of impairment. Basic ADL performance impacted to different degrees on QoL across dementia stages and countries. Interventions aimed at maintaining independence or QoL need to target different ADLs across different dementia stages and perhaps also tailor interventions to the context of different countries. Findings contribute to the development of non-pharmaceutical interventions and governmental pledges to promote independence in dementia.

Balance in humans is a motor skill based on complex multimodal sensing, processing and control. Ability to maintain balance in activities of daily living (ADL) is compromised due to aging, diseases, injuries and environmental factors. Center for Disease Control and Prevention (CDC) estimate of the costs of falls among older adults was $34 billion in 2013 and is expected to reach $54.9 billion in 2020. In this paper, we present a brief review of balance impairments followed by subjective and objective tools currently used in clinical settings for human balance assessment. We propose a novel computer vision (CV) based approach as a candidate for functional balance test. The test will take less than a minute to administer and expected to be objective, repeatable and highly discriminative in quantifying ability to maintain posture and balance. We present an informal study with preliminary data from 10 healthy volunteers, and compare performance with a balance assessment system called BTrackS Balance Assessment Board. Our results show high degree of correlation with BTrackS. The proposed system promises to be a good candidate for objective functional balance tests and warrants further investigations to assess validity in clinical settings, including acute care, long term care and assisted living care facilities. Our long term goals include non-intrusive approaches to assess balance competence during ADL in independent living environments.

Previous studies have reported that self-rated health (SRH) predicts subsequent mortality. However, less is known about the association between SRH and functional ability. The aim of this study was to examine whether SRH predicts decline in basic activities of daily living (ADL), even after adjustment for depression, among community-dwelling older adults in Japan. A three-year prospective cohort study was conducted among 654 residents aged 65 years and older without disability in performing basic ADL at baseline. SRH was assessed using a visual analogue scale (range; 0-100), and dichotomized into low and high groups. Information on functional ability, sociodemographic factors, depressive symptoms, and medical conditions were obtained using a self-administered questionnaire. Logistic regression analysis was used to examine the association between baseline SRH and functional decline three years later. One hundred and eight (16.5%) participants reported a decline in basic ADL at the three-year follow-up. Multiple logistic regression analysis showed that the low SRH group had a higher risk for functional decline compared to the high SRH group, even after controlling for potential confounding factors (odds ratio (OR) = 2.4; 95% confidence interval (CI) = 1.3-4.4). Furthermore, a 10-point difference in SRH score was associated with subsequent functional decline (OR = 1.37; 95% CI = 1.16-1.61). SRH was an independent predictor of functional decline. SRH could be a simple assessment tool for predicting the loss or maintenance of functional ability in community-dwelling older adults. Positive self-evaluation might be useful to maintain an active lifestyle and stay healthy.

This study examined the contribution of object perception and spatial localization to functional dependence among Alzheimer's disease (AD) patients. Forty patients with probable AD completed measures assessing verbal recognition memory, working memory, object perception, spatial localization, semantic knowledge, and global cognition. Primary caregivers completed a measure of activities of daily living (ADLs) that included instrumental and basic self-care subscales (i.e., IADLs and BADLs, respectively). Stepwise multiple regressions revealed that global cognition accounted for significant portions of variance among the ADL total, IADL, and BADL scores. However, when global cognition was removed from the model, object perception was the only significant cognitive predictor of the ADL total and IADL subscale scores, accounting for 18.5% and 19.3% of the variance, respectively. When considering multiple cognitive components simultaneously, object perception and the integrity of the inferotemporal cortex is important in the completion of functional abilities in general and IADLs in particular among AD patients.

OBJECTIVE: To compare assisted living residents and nursing home residents on outcome trajectories for three outcomes: ability to perform activities of daily living (ADLs), psychological well-being, and pain and discomfort. DATA SOURCES/STUDY SETTING: A representative sample of one-third of the census from 38 participating assisted living facilities (N = 605) and two-fifths of the census from 31 participating nursing facilities (N = 610). STUDY DESIGN: A longitudinal design using hierarchical linear models to examine how setting (being in an assisted living setting or in a nursing home) affected growth trajectories for each outcome studied when adjusting for other resident characteristics. DATA COLLECTION: Residents or their proxies were interviewed and chart reviews done at baseline, six months, and one year. All baseline data were collected between August 1995 and May 1996. PRINCIPAL FINDINGS: We found differences in case mix between assisted living and nursing facility residents but no differences in outcome trajectories for ADLs, psychological well-being, and pain and discomfort. For ADLs and pain and discomfort on average, residents in both settings experienced change over the study period. For psychological well-being, residents experienced no change on average. CONCLUSIONS: The lack of difference in growth trajectories for ADLs, pain and discomfort, and psychological well-being between the two settings was noteworthy. PMID:11324746

Sensors available on mobile devices allow the automatic identification of Activities of Daily Living (ADL). This paper describes an approach for the creation of a framework for the identification of ADL, taking into account several concepts, including data acquisition, data processing, data fusion, and pattern recognition. These concepts can be mapped onto different modules of the framework. The proposed framework should perform the identification of ADL without Internet connection, performing these tasks locally on the mobile device, taking in account the hardware and software limitations of these devices. The main purpose of this paper is to present a new approach for the creation of a framework for the recognition of ADL, analyzing the allowed sensors available in the mobile devices, and the existing methods available in the literature.

A stable yellow-seeded variety is the breeding goal for obtaining the ideal rapeseed (Brassica napus L.) plant, and the amount of acid detergent lignin (ADL) in the seeds and the hull content (HC) are often used as yellow-seeded rapeseed screening indices. In this study, a genome-wide association analysis of 520 accessions was performed using the Q + K model with a total of 31,839 single-nucleotide polymorphism (SNP) sites. As a result, three significant associations on the B. napus chromosomes A05, A09, and C05 were detected for seed ADL content. The peak SNPs were within 9.27, 14.22, and 20.86 kb of the key genes BnaA.PAL4, BnaA.CAD2/BnaA.CAD3, and BnaC.CCR1, respectively. Further analyses were performed on the major locus of A05, which was also detected in the seed HC examination. A comparison of our genome-wide association study (GWAS) results and previous linkage mappings revealed a common chromosomal region on A09, which indicates that GWAS can be used as a powerful complementary strategy for dissecting complex traits in B. napus. Genomic selection (GS) utilizing the significant SNP markers based on the GWAS results exhibited increased predictive ability, indicating that the predictive ability of a given model can be substantially improved by using GWAS and GS.

Determining Nurse Aide Staffing Requirements to Provide Care Based on Resident Workload: A Discrete Event Simulation Model.

Schnelle, John F; Schroyer, L Dale; Saraf, Avantika A; Simmons, Sandra F

Nursing aides provide most of the labor-intensive activities of daily living (ADL) care to nursing home (NH) residents. Currently, most NHs do not determine nurse aide staffing requirements based on the time to provide ADL care for their unique resident population. The lack of an objective method to determine nurse aide staffing requirements suggests that many NHs could be understaffed in their capacity to provide consistent ADL care to all residents in need. Discrete event simulation (DES) mathematically models key work parameters (eg, time to provide an episode of care and available staff) to predict the ability of the work setting to provide care over time and offers an objective method to determine nurse aide staffing needs in NHs. This study had 2 primary objectives: (1) to describe the relationship between ADL workload and the level of nurse aide staffing reported by NHs; and, (2) to use a DES model to determine the relationship between ADL workload and nurse aide staffing necessary for consistent, timely ADL care. Minimum Data Set data related to the level of dependency on staff for ADL care for residents in over 13,500 NHs nationwide were converted into 7 workload categories that captured 98% of all residents. In addition, data related to the time to provide care for the ADLs within each workload category was used to calculate a workload score for each facility. The correlation between workload and reported nurse aide staffing levels was calculated to determine the association between staffing reported by NHs and workload. Simulations to project staffing requirements necessary to provide ADL care were then conducted for 65 different workload scenarios, which included 13 different nurse aide staffing levels (ranging from 1.6 to 4.0 total hours per resident day) and 5 different workload percentiles (ranging from the 5th to the 95th percentile). The purpose of the simulation model was to determine the staffing necessary to provide care within each workload percentile based on resident ADL care needs and compare the simulated staffing projections to the NH reported staffing levels. The percentage of scheduled care time that was omitted was estimated by the simulation model for each of the 65 workload scenarios using optimistic assumptions about staff productivity and efficiency. There was a low correlation between ADL workload and reported nurse aide staffing (Pearson = .11; P < .01), which suggests that most of the 13,500 NHs were not using ADL acuity to determine nurse aide staffing levels. Based on the DES model, the nurse aide staffing required for ADL care that would result in a rate of care omissions below 10% ranged from 2.8 hours/resident/day for NHs with a low workload (5th percentile) to 3.6 hours/resident/day for NHs with a high workload (95th percentile). In contrast, NHs reported staffing levels that ranged from an average of 2.3 to 2.5 hours/resident/day across all 5 workload percentiles. Higher workload NHs had the largest discrepancies between reported and predicted nurse aide staffing levels. The average nurse aide staffing levels reported by NHs falls below the level of staffing predicted as necessary to provide consistent ADL care to all residents in need. DES methodology can be used to determine nurse aide staffing requirements to provide ADL care and simulate management interventions to improve care efficiency and quality.

Dementia is a frequent diagnosis in geriatric rehabilitation. Studies in patients with dementia on the development of their cognitive status during rehabilitation and its relation to functional outcomes have been scarce. To describe the changes in cognitive status in patients with dementia during inpatient rehabilitation and to determine its association with patient characteristics and rehabilitation outcome. Cohort study in a geriatric rehabilitation center with data collection at admission and discharge. Outcome measures were change in global and domain-related cognitive functioning and its association with activities of daily living (ADL) and discharge home. 154 patients (mean age 83.7 years) diagnosed with mild to moderate dementia were included. Cognitive performance significantly improved from admission to discharge for all cognitive variables tested (p < 0.001 to 0.03). Change in global cognitive functioning, executive functions, and episodic memory were positively associated with ADL recovery. Change in global cognitive functioning predicted ADL improvements (β= 0.32; p = 0.006). Only 7.8% of patients, characterized by worse ADL and motor abilities as well as higher frailty scores at admission, deteriorated in global cognitive scores. In comparison to patients with stable or improved cognition, these patients showed least improvements in ADL-scores (4.1 versus 12.5) and a trend for higher institutionalization (50% versus 26.5%). The findings highlight the potential of patients with dementia to recover cognitive functioning during rehabilitation. Cognitive change represents an independent rehabilitation outcome and a prognostic factor for successful rehabilitation suggesting that specific interventions are indicated to maintain and enhance cognitive functioning in these highly vulnerable patients.

JPSS is a next generation satellite system that is planned to be launched in 2017. The satellites will carry a suite of sensors that are already on board the Suomi National Polar-orbiting Partnership (S-NPP) satellite. The NOAA/NESDIS/STAR Algorithm Integration Team (AIT) works within the Algorithm Development Library (ADL) framework which mimics the operational JPSS Interface Data Processing Segment (IDPS). The AIT contributes in development, integration and testing of scientific algorithms employed in the IDPS. This presentation discusses cryosphere related activities performed in ADL. The addition of a new ancillary data set - NOAA Global Multisensor Automated Snow/Ice data (GMASI) - with ADL code modifications is described. Preliminary GMASI impact on the gridded Snow/Ice product is estimated. Several modifications to the Ice Age algorithm that demonstrates mis-classification of ice type for certain areas/time periods are tested in the ADL. Sensitivity runs for day time, night time and terminator zone are performed and presented. Comparisons between the original and modified versions of the Ice Age algorithm are also presented.

Northwest Shanxi is located on the farming-pastoral ecotone of northern China, where aeolian desertification is one of the most serious environmental and socioeconomic issues. The remote sensing image and geostatistical approach were implemented to estimate aeolian desertified land (ADL) dynamic variations from 1975 to 2015. Results showed that the ADL covered 11,685.21 km 2 (82.29%) of the study area in 2015, the majority of which was classified as a light or moderate degree. The area of ADL gradually expanded at an increasing rate of 87.37 km 2 a -1 during the 1975-2000 periods. More specifically, the area of ADL has increased by 1259.23 km 2 from 1975 to 1990 and by 924.96 km 2 from 1990 to 2000, respectively. In contrast, spatial transfer of ADL areas has dwindled by 2365.85 km 2 with a net decrease of 157.72 km 2 a -1 , and the mitigated areas of aeolian desertification were 10,602.24 km 2 between 2000 and 2015. During the past 40 years, the gravity center of ADL migrated to southeast until 2000 and moved northwest in 2000-2015. From 1975 to 2000, the migration distance of severe ADL was the largest, migrated toward the northwest by 19.03 km in 1975-1990 and by 20.16 km in 1990-2000, respectively. From 2000 to 2015, the migration distance of light ADL was the largest, 27.54 km migrated to the northwest. Aeolian desertification rapidly expanded from 1975 to 2000 under the combination of climate change and intensive human activities. Since the year of 2000, ecological engineering strategy initiated by the governments has been the dominant contributor to the aeolian desertification severity reversal. Aeolian desertification prevention is a complicated process. Both the central and local government should play a critical role in the rehabilitation of ADL in the long term.

Excess disability among nursing home elder persons can be prevented or remediated. Because of self-selected disuse and caregiver support of dependency, nursing home residents are likely to develop excess disability. No study was found to test a theory-based program aimed at improving elder persons' self-care abilities for Taiwanese nursing home elder persons who are at risk for developing excess disability. The purpose of this study was to test the effectiveness of a theory-based intervention program on self-care, specifically on activities of daily living (ADLs) performance among nursing home elder persons in Taiwan. A secondary aim was to determine the correlation between ADLs performance and three bliss concepts: life satisfaction, self-esteem, and motivation in health behavior. This study used a quasi-experimental, two-group, pretest-posttest design. Forty-two qualified participants were recruited from two nursing homes located in southern Taiwan and assigned to either the experimental group (n = 21) or the comparison group (n = 21). Participants in the experimental group received the Self-Care Self-Efficacy Enhancement Program (SCSEEP), and those in the comparison group received biweekly social visits for 6 weeks. Levels of ADLs performance were measured by Tappen's Refined ADL Assessment Scale. Life satisfaction was measured by Adams' Life Satisfaction Index A. Self-esteem was measured by Rosenberg's Self-Esteem Scale. Motivation in health behavior was measured by Cox's Health Self-Determinism Index. Elder persons receiving the SCSEEP had significant improvement in feeding, dressing, grooming, and washing activities. Self-esteem (p = .011) and life satisfaction (p = .033) but not motivation in health behavior (p = .282) were positively correlated with levels of ADLs performance. The SCSEEP provides a theory-based intervention model for Taiwanese nursing home elder persons aimed at improving ADLs performance. Further research with a larger sample size is needed to determine the long-term maintenance and effectiveness of this theory-driven SCSEEP in specific culture groups.

For patients with severe hemiplegia in a rehabilitation hospital, early prediction of the functional prognosis and outcomes is challenging. The purpose of this study was to create and verify a prognostic scale in severely hemiplegic stroke patients and allowing for prediction of (1) the ability to walk at the time of hospital discharge, (2) the ability to carry out activities of daily living (ADL), and (3) feasibility of home discharge. The study was conducted on 80 severely hemiplegic stroke patients. A prognostic scale was created as an analysis method using the following items: mini-mental state examination (MMSE) at the time of admission, modified NIH stroke scale (m-NIHSS); trunk control test (TCT); and the ratio of the knee extensor strength on the non-paralyzed side to the body weight (KES/BW-US). We verified the reliability and validity of this scale. We established a prognostic scale using the MMSE, m-NIHSS, TCT, and KES/BW-US. A score of 56.8 or higher on the prognostic scale suggested that the patient would be able to walk and that assistance with ADL would be unnecessary at the time of hospital discharge. In addition, a score of 41.3 points indicated that the patient's return home was feasible. The reliability and the results were in good agreement. These findings showed that the ability or inability to walk was predictable in 85%, the need of assistance with ADL in 82.5%, and the feasibility of home return in 76.3% of cases. At the time of admission, four evaluation items permitted the prediction of three outcomes at time of discharge. Our formula predicts three outcomes with an accuracy of more than 76%.

In the present study we explored cognitive and functional deficits in patients with multidomain mild cognitive impairment (MCI), patients with dementia, and healthy age-matched control participants using the Cognitive Scale for Basic and Instrumental Activities of Daily Living, a new preliminary informant-based assessment tool. This tool allowed us to evaluate four key cognitive abilities-task memory schema, error detection, problem solving, and task self-initiation-in a range of basic and instrumental activities of daily living (BADL and IADL, respectively). The first part of the present study was devoted to testing the psychometric adequateness of this new informant-based tool and its convergent validity with other global functioning and neuropsychological measures. The second part of the study was aimed at finding the patterns of everyday cognitive factors that best discriminate between the three groups. We found that patients with dementia exhibited impairment in all cognitive abilities in both basic and instrumental activities. By contrast, patients with MCI were found to have preserved task memory schema in both types of ADL; however, such patients exhibited deficits in error detection and task self-initiation but only in IADL. Finally, patients with MCI also showed a generalized problem solving deficit that affected even BADL. Studying various cognitive processes instantiated in specific ADL differing in complexity seems a promising strategy to further understand the specific relationships between cognition and function in these and other cognitively impaired populations.

A high incidence of limitations in daily functioning is seen in older adults with intellectual disabilities (ID), along with poor physical fitness levels. The aim of this study was to assess the predictive value of physical fitness for daily functioning after 3 years, in 602 older adults with borderline to profound ID (≥ 50 years). At baseline, physical fitness levels and daily functioning (operationalized as basic activities of daily living [ADL] and mobility) were assessed. After 3 years, the measurements of daily functioning were repeated. At follow-up, 12.6% of the participants were completely independent in ADL and 48.5% had no mobility limitations. More than half of the participants (54.8%) declined in their ability to perform ADL and 37.5% declined in their mobility. Manual dexterity, visual reaction time, balance, comfortable and fast gait speed, muscular endurance, and cardiorespiratory fitness were significant predictors for a decline in ADL. For a decline in mobility, manual dexterity, balance, comfortable and fast walking speed, grip strength, muscular endurance, and cardiorespiratory fitness were all significant predictors. This proves the predictive validity of these physical fitness tests for daily functioning and stresses the importance of using physical fitness tests and implementing physical fitness enhancing programs in the care for older adults with ID.

To determine the most significant clinical predictors that influence driving ability in Parkinson disease (PD). National-multi-centre, cross-sectional study covering PD outpatients. Clinical assessment was based on the following questionnaires: cognition (SCOPA-Cog); motor impairment and disabilities (SCOPA motor); depression/anxiety; sleep (SCOPA-Sleep); psychosis and severity/global impairment (HY and CISI-PD). Driving status data was obtained using a standardized questionnaire. Comparisons between drivers and ex-drivers were calculated using chi(2) and Student t-tests as appropriate. Multi-variate logistic regression analysis was performed to identify independent driving ability clinical predictors. Compared with the drivers, the ex-drivers were older (p = 0.00005), had longer disease duration (p = 0.03), had more overall cognitive dysfunction (p = 0.004) and had greater motor impairment, as measured by the CISI (p = 0.02), HY stage (p = 0.034) and by the SCOPA-motor scale (p = 0.002) and difficulty in activities of daily life (p = 0.002). In the regression model analysis, aging and ADL impairment were the principal clinical predictors that differentiated drivers from ex-drivers. Although overall driving impairment in PD is associated with advancing disease severity, driving ability seems to be more strongly influenced by age and ADL impairment. Multi-disciplinary teams are required to assess driving ability in patients with PD and develop rehabilitation measures for safer driving.

Measuring physical activity in people with rheumatoid arthritis (RA) is of great importance in light of the increased mortality in this population due to cardiovascular disease. Validation of activity monitors in specific populations is recommended to ensure the accuracy of physical activity measurement. Thus, the purpose of this study was to determine the validity of the SenseWear Pro3 Armband (SWA) as a measure of physical activity during activities of daily living (ADL) in people with RA. Fourteen subjects (8 men and 6 women) with a diagnosis of RA were recruited from rheumatology clinics at the Mid-Western Regional Hospitals, Limerick, Ireland. Participants undertook a series of ADL of varying intensities. The SWA was compared to the criterion measures of the Oxycon Mobile indirect calorimetry system (energy expenditure in kJ) and of manual video observation (step count). Bland and Altman, intraclass correlation coefficient (ICC), and correlation analyses were done using SPSS, version 19.0. The SWA showed substantial agreement (ICC 0.717, P < 0.001) and a strong relationship (Pearson's correlation coefficient = 0.852) compared with the criterion measure when estimating energy expenditure during ADL. However, it was found that the SWA overestimated energy expenditure, particularly at higher intensity levels. The ability of the SWA to estimate step counts during ADL was poor (ICC 0.304, P = 0.038). The SWA can be considered a valid tool to estimate energy expenditure during ADL in the RA population; however, attention should be paid to its tendency to overestimate energy expenditure.

To compare the effects of exercise with those of a structured nonphysical intervention on ability to perform activities of daily living (ADLs) and physical and cognitive function of persons with dementia (PWDs) living in nursing homes (NH). Cluster-randomized pilot-controlled trial. Seven French NHs. PWDs living in NHs. NHs were randomized to an exercise group (4 NHs, n = 47) or structured social activity group (3 NHs, n = 50) for a 24-week intervention performed twice per week for 60 minutes per session. The main endpoint was ADL performance (Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory for Severe Alzheimer's Disease Scale (ADCS-ADL-sev); range 0-54, higher is better); secondary endpoints were overall cognitive function (Mini-Mental State Examination (MMSE)) and performance-based tests of physical function (Short Physical Performance Battery (SPPB), usual gait speed). Ninety-one participants with at least one postbaseline ADL assessment were included in efficacy analysis. Groups differed at baseline in terms of sex, neuropsychiatric symptoms, and nutritional status. Multilevel analysis adjusted for baseline differences between groups found no significant difference between effects of exercise and social activity (group-by-time interaction), with adjusted mean differences at 6 months of 1.9 points for ADCS-ADL-sev and 0.55 points for MMSE favoring social activity and 0.6 points for SPPB and 0.05 m/s favoring exercise. Adverse events did not differ between groups, except that the social activity group had more falls than the exercise group. A larger, longer trial is required to determine whether exercise has greater health benefits than nonphysical interventions for institutionalized PWDs. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Simple Counts of ADL Dependencies Do Not Adequately Reflect Older Adults' Preferences toward States of Functional Impairment

Objective To use unweighted counts of dependencies in Activities of Daily Living (ADLs) to assess the impact of functional impairment requires an assumption of equal preferences for each ADL dependency. To test this assumption, we analyzed standard gamble utilities of single and combination ADL dependencies among older adults. Study Design and Setting: Four hundred older adults used multimedia software (FLAIR1) to report standard gamble utilities for their current health and hypothetical health states of dependency in each of 7 ADLs and 8 of 30 combinations of ADL dependencies. Results Utilities for health states of multiple ADL dependencies were often greater than for states of single ADL dependencies. Dependence in eating, the ADL dependency with the lowest utility rating of the single ADL dependencies, ranked lower than 7 combination states. Similarly, some combination states with fewer ADL dependencies had lower utilities than those with more ADL dependencies. These findings were consistent across groups by gender, age, and education. Conclusion Our results suggest that the count of ADL dependencies does not adequately represent the utility for a health state. Cost-effectiveness analyses and other evaluations of programs that prevent or treat functional dependency should apply utility-weights rather than relying on simple ADL counts. PMID:18722749

Algorithm Development Library (ADL) is a framework that mimics the operational system IDPS (Interface Data Processing Segment) that is currently being used to process data from instruments aboard Suomi National Polar-orbiting Partnership (S-NPP) satellite. The satellite was launched successfully in October 2011. The Cross-track Infrared and Microwave Sounder Suite (CrIMSS) consists of the Advanced Technology Microwave Sounder (ATMS) and Cross-track Infrared Sounder (CrIS) instruments that are on-board of S-NPP. These instruments will also be on-board of JPSS (Joint Polar Satellite System) that will be launched in early 2017. The primary products of the CrIMSS Environmental Data Record (EDR) include global atmospheric vertical temperature, moisture, and pressure profiles (AVTP, AVMP and AVPP) and Ozone IP (Intermediate Product from CrIS radiances). Several algorithm updates have recently been proposed by CrIMSS scientists that include fixes to the handling of forward modeling errors, a more conservative identification of clear scenes, indexing corrections for daytime products, and relaxed constraints between surface temperature and air temperature for daytime land scenes. We have integrated these improvements into the ADL framework. This work compares the results from ADL emulation of future IDPS system incorporating all the suggested algorithm updates with the current official processing results by qualitative and quantitative evaluations. The results prove these algorithm updates improve science product quality.

The purpose of this study was to determine whether providing fall risk information to long-term care (LTC) nurses affects restraint use, activities of daily living (ADL), falls, and nurse fears about patient falls. One-hundred and fifty LTC residents were randomized to a fall risk assessment intervention or care-as-usual group. Hypotheses were tested using analyses of variance and path analyses. Restraint use was associated with lower ADL scores. In the intervention group, there ceased to be significant relationships between nurse fears about falls and patient falls (after controlling for actual patient risk; post-intervention, nurse fears about falls were based on realistic appraisals), and between fears and restraints (i.e. unjustified nurse fears became less likely to lead to unjustified restraint use). No group differences in falls were identified. Despite a lack of group differences in falls, results show initial promise in potentially impacting resident care. Increasing intervention intensity may lead to fall reductions in future research. Given the high prevalence rates of falls in LTC and associated injuries, prevention programs are important. Nurse fears about patient falls may impact upon restraint use which, when excessive, can interfere with the patient's ability to perform ADL. Excessive restraint use, due to unjustified nurse fears, could also lead to falls. Providing accurate, concise information to nursing staff about patient fall risk may aid in reducing the association between unjustified nurse fears and the resulting restraint use that can have potential negative consequences.

To determine how development of delirium after surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI) could predict activity of daily living (ADL) and instrumental ADLs (IADL) disability, cognitive function, and self-reported health in individuals aged 80 and older. Prospective cohort study. Tertiary university hospital. Individuals aged 80 and older undergoing elective SAVR or TAVI (N = 136). Delirium was assessed for 5 days using the Confusion Assessment Method. The Barthel Index, Nottingham Extended ADL Scale, and SF-12 were used to determine ADL and IADL ability and self-reported health at baseline and 1- and 6-month follow-up. Cognition was assessed using the Mini-Mental State Examination at baseline and 6-month follow-up. Participants had lower IADL scores 1 month after SAVR than at baseline (baseline 58, 1 month: delirium 42, no delirium 50, P ≤ .02), but scores had returned to baseline levels at 6 months. The Medical Outcomes Study 12-item Short-Form Health Survey (SF-12) Physical Component Summary (PCS) score was higher at 6-month follow-up (48) than at baseline (39), especially in participants who did not develop delirium (P < .001). No differences in other outcomes were found. Regression models suggest that delirium may help predict IADL disability 1 month after baseline (P ≤ .07) but does not predict large differences in ADL disability, cognitive function, or SF-12-scores. Individuals who underwent TAVI and developed delirium had lower ADL (baseline 19, 1-month 16, P < .001) and IADL (baseline 49, 1-month 40, P = .003) scores at 1-month follow-up. SF-12 PCS score (baseline 30) increased from baseline to 1- (35, P = .04) and 6- (35, P = .02) month follow-up in individuals who underwent TAVI and did not develop delirium. Delirium after TAVI predicted greater ADL and IADL disability at 1-month but not at 6-month follow-up. Individuals who develop delirium after SAVR and TAVI have poorer short-term IADL function but do not seem to have long-term reductions in physical, mental, or self-reported health. © 2016 The Authors.

Knee complaints and their accompanying functional impairments are frequent problems encountered by healthcare practitioners worldwide. Plenty of functional scoring systems were developed and validated to give a relative estimation about the knee function. Despite the wide geographic distribution of Arabic language in the Middle East and North Africa, it is rare to find a validated knee function scale in Arabic. The present study is aimed to translate, validate, and culturally adjust the Knee Outcome Survey: Activities of Daily Living Scale (KOS-ADLS) into Arabic language for future use among Arabic-speaking patients. Permission for translation was obtained from the copyrights holder. Two different teams of high-level clinical and linguistic expertise conducted translation process blindly. Forward-backward translation technique was implemented to ensure preservation of the main conceptual content. Main study consisted of 280 subjects. Reliability was examined by test-retest pilot study. Visual Analogue Scale (VAS), Get Up and Go (GUG) Test, Ascending/Descending Stairs (A/D Stairs), and Subjective Assessment of Function (SAF) were conducted concurrently to show the validity of Arabic KOS-ADLS statistically in relation to these scales. Final translated version showed no significant discrepancies. Minor adaptive adjustment was required to fit Arabian cultural background. Internal consistency was favourable (Cronbach's alpha 0.90). Patients' scoring on Arabic KOS-ADLS appeared relatively consistent with their scoring on VAS, GUG, A/D Stairs, and SAF. A significant linear relationship was demonstrated between SAF and total KOS-ADLS scores on regression analysis (adj. R 2  = 0.548). Arabic KOS-ADLS, as its English counterpart, was found to be a simple, valid, and useful instrument for knee function evaluation. Arabic version of KOS-ADLS represents a promising candidate for unconditional use among Arabic-speaking patients with knee complaints.

Many cancer patients report unmet rehabilitation needs. Rehabilitation may include activities of daily living (ADL) tasks, but little is known about how cancer patients perform these tasks and how they prioritize their daily activities. Hence, this study aims to identify and characterize ADL task performance problems among a group of adult disabled hospitalized cancer patients using interview and questionnaire data. Cross-sectional study on prevalence of ADL task performance problems experienced by disabled hospitalized cancer patients using the Activities of Daily Living Questionnaire (ADL-Q) (n = 118) and the Canadian Occupational Performance Measure (COPM) (n = 55). All 118 patients reported problems with ADL task performance. Based on the ADL-Q patients reported more problems within instrumental (I-)ADL than personal (P-)ADL. In both I-ADL and P-ADL the results differed between women and men. There was significant overlap between problems identified using the COPM and the ADL-Q instruments. RESULTS from the COPM showed that 65% of problems were related to self-care, 25% to leisure, and 19% to productivity. Using both instruments identified more ADL problems than when using only one of the instruments. Adult hospitalized disabled cancer patients experience a high degree and variation in difficulties performing ADL, illustrating the need for a comprehensively planned assessment of problems and needs.

Chronic Obstructive Pulmonary Disease (COPD) is a long-term condition where activities of daily living (ADLs) may be very restricted; people with COPD need to prioritize what is important to them. We conducted a meta-ethnography to understand which ADLs are valued and why, systematically searching for articles including experiences of ADLs and organizing themes from the articles into five linked concepts: (a) caring for the body, (b) caring for the personal environment, (c) moving between spaces, (d) interacting with others, and (e) selfhood across time. In addition, we identified three key aspects of personal integrity: effectiveness, connectedness, and control. We found that ADLs were valued if they increased integrity; however, this process was also informed by gendered roles and social values. People whose sense of control depended on effectiveness often found accepting help very difficult to bear; therefore, redefining control as situational and relational may help enjoyment of activities that are possible. © The Author(s) 2016.

The Classic Measure of Disability in Activities of Daily Living Is Biased by Age but an Expanded IADL/ADL Measure Is Not

PubMed Central

2010-01-01

Objectives. To evaluate, by age, the performance of 2 disability measures based on needing help: one using 5 classic activities of daily living (ADL) and another using an expanded set of 14 activities including instrumental activities of daily living (IADL), walking, getting outside, and ADL (IADL/ADL). Methods. Guttman and item response theory (IRT) scaling methods are used with a large (N = 25,470) nationally representative household survey of individuals aged 18 years and older. Results. Guttman scalability of the ADL items increases steadily with age, reaching a high level at ages 75 years and older. That is reflected in an IRT model by age-related differential item functioning (DIF) resulting in age-biased measurement of ADL. Guttman scalability of the IADL/ADL items also increases with age but is lower than the ADL. Although age-related DIF also occurs with IADL/ADL items, DIF is lower in magnitude and balances out without causing age bias. Discussion. An IADL/ADL scale measuring need for help is hierarchical, unidimensional, and unbiased by age. It has greater content validity for measuring need for help in the community and shows greater sensitivity by age than the classic ADL measure. As demand for community services is increasing among adults of all ages, an expanded IADL/ADL measure is more useful than ADL. PMID:20100786

To determine the effects of rivastigmine patch associated with physical exercise versus rivastigmine patch alone in quality of life (QOL), cognition, activities of daily living (ADL) and functional mobility in Alzheimer's disease (AD)subjects. A randomized, controlled, single-blinded trial was conducted in 40 patients with mild to moderate stages of AD. All patients were daily treated with rivastigmine transdermal patch at a stable dose of 4.6 mg and randomized into two groups: physical exercises or control. The exercise program consisted of aerobic, flexibility, strength and balance movements, twice a week for 6 months. Main outcomes were Quality of Life in Alzheimer's disease scale (QOL), Activities of Daily Living Questionnaire (ADL), Mini-Mental State Examination (MMSE) and "Time Up and Go Test". Thirty-four patients completed the study. After 6 months, there was a significant improvement in QOL of patients randomized to physical exercise group (P< 0.05). In both groups, there was an improvement on caregivers QOL (P>0.05). When considering cognitive functions, there was no difference between groups. The ability to perform ADL worsened in the group enrolled to RTP alone. There was an improvement in functional mobility in the group treated with RTP. Our results suggest that the association between physical exercises and RTP improves QOL in patients with AD. Cognition remained unchanged in both groups. Regarding the effect of physical exercises in ADL, further trials are necessary to confirm these results.

In primary prevention trials for Alzheimer disease, the inception cohort typically has normal or minimally impaired complex activities of daily living (ADL). ADL change during a trial could trigger detailed evaluation or serve as an outcome measure. A brief, easily administered, and reliable ADL rating scale would assist prevention studies. To develop an ADL scale for prevention trials that allows self-rating or completion by informants. The Activities of Daily Living-Prevention Instrument (ADL-PI) was developed, comprising 15 ADL and 5 physical function questions. Six hundred forty-four elderly subjects participating in the Prevention Instrument Project completed a self-rated version of the ADL-PI, and informants for 632 subjects completed an informant version. Informants also completed a Mild Cognitive Impairment (MCI) ADL questionnaire to allow comparisons. Subjects performed well on all ADL scales at baseline. Completion of the ADL-PI questionnaires at home or in-clinic yielded comparable information. Scores from baseline to 3 months had good reliability. The ADL-PI, obtained from either self-report or informants, discriminated between subjects rated as CDR 0 and CDR 0.5. Subjects with worse baseline cognitive performance also had slightly worse ADL-PI scores. Preliminary analysis indicates that subjects who triggered cognitive evaluations had slightly lower baseline ADL-PI scores by both self and informant reports. The ADL-PI can be completed at home or in clinic, and has adequate reliability. The utility of self-administered and informant versions and predictive value of reported deficits requires further follow-up.

Forty-four community-dwelling family caregivers (the caregiver group: CG) and 50 elderly control participants (the non-caregiver group: NCG) participated in this study. We measured salivary human herpesvirus (HHV)-6 and -7 DNA levels and the Chalder fatigue scale (CFS) to assess levels of fatigue; we also measured the Center for Epidemiologic Studies-Depression Scale, Physical Activity Scale for the Elderly, Zarit Caregiver Burden Interview, Mini-Mental State Examination, Assessment of Motor and Process Skills, and Dementia Behavior Disturbance Scale. For CG, the salivary HHV-6 DNA levels and CFS scores were significantly higher than those in NCG. The salivary HHV-6 DNA levels in CG were significantly correlated with depressive symptoms, the cognitive function of the patients, and the activities of daily living/instrumental activities of daily living (ADL/IADL) abilities of the patients. The CFS scores in CG significantly correlated with caregiver burden, depression symptoms, leisure physical activity, the number of other family caregivers, and the hours spent for caregiving per week, as well as with behavior disturbances and ADL/IADL abilities. The salivary HHV-6 DNA levels may be added as a new biomarker for caregiver exhaustion. We concluded that fatigue assessments should be performed by not only a questionnaire, such as the CFS, but also by a biomarker search, such as HHV-6, when estimating the caregiver burden for family caregivers of people with dementia.

Objectives To establish nationally representative estimates of the prevalence of self-reported difficulty and inability to walk ¼ mile among older adults and to identify the characteristics independently associated with difficulty or inability to walk ¼ mile. Design Cross-sectional analysis of data from the 2003 Cost and Use Medicare Current Beneficiary Survey. Setting Community. Participants 9563 community-dwelling Medicare beneficiaries aged 65 years or older, representing an estimated total population of 34.2 million older adults. Measurements Self-reported ability to walk ¼ mile, sociodemographics, chronic conditions, body mass index, smoking, and functional status. Results In 2003, an estimated 9.5 million aged Medicare beneficiaries had difficulty walking ¼ mile and 5.9 million were unable. Among the 20.2 million older adults with no difficulty in basic or instrumental activities of daily living (ADL), an estimated 4.3 million (21%) had limited ability to walk ¼ mile. Having difficulty or being unable to walk ¼ mile was independently associated with older age, female sex, non-Hispanic ethnicity, lower educational level, Medicaid entitlement, most chronic medical conditions, current smoking, and being overweight or obese. Conclusion Almost half of older adults, and 20% of those reporting no ADL limitations, report limited ability to walk ¼ mile. Among functionally independent older adults, reported ability to walk ¼ mile can identify vulnerable older adults with greater medical problems and fewer resources, and may be a valuable clinical marker in planning their care. Future work is needed to determine the association between ¼ mile walk ability and subsequent functional decline and healthcare utilization. PMID:20210817

To identify factors, individual and work related, influencing work ability, and to assess the association between work ability and employment status, activities of daily life (ADLs) and quality of life in patients with SSc. Fifty-seven consecutive patients (53 females/4 males) with SSc (47 lcSSc/10 dcSSc) were included. Median age was 58 [interquartile range (IQR) 47-62] years and disease duration 14 (9-19) years. The patients were assessed for socio-demographic characteristics, disease parameters, symptoms, work ability, empowerment and adaptations in a workplace, social support, ADLs and quality of life. Work ability, assessed with the Work Ability Index (WAI) could be evaluated in 48 of 57 patients. The correlation between employment status and WAI was good (r(s) = 0.79, P < 0.001). Thirteen patients had good or excellent WAI, 15 had less good and 20 had poor WAI. There were no significant differences between subgroups of WAI and socio-demographic characteristics, disease duration or degree of skin and lung involvement. However, patients with good WAI expressed milder perceived symptoms (pain, fatigue and impaired hand function; P < 0.001). Patients with better WAI had better competence (P < 0.001), better possibility of adaptations at work (P < 0.01) and impact at work (P < 0.01) than those with poorer WAI. In SSc, pain, fatigue and impaired hand function have a dominant impact on the WAI. Employment interventions should include support in job adaptations as well as self-management strategies to help patients deal with pain and fatigue and to enhance the confidence to perform their work.

Mobility, such as walking 1/4 mile, is a valuable but underutilized health indicator among older adults. For mobility to be successfully integrated into clinical practice and health policy, an easily assessed marker that predicts subsequent health outcomes is required. To determine the association between mobility, defined as self-reported ability to walk 1/4 mile, and mortality, functional decline, and health care utilization and costs during the subsequent year. Analysis of longitudinal data from the 2003-2004 Medicare Current Beneficiary Survey, a nationally representative sample of Medicare beneficiaries. Participants comprised 5895 community-dwelling adults aged 65 years or older enrolled in Medicare. Mobility (self-reported ability to walk 1/4 mile), mortality, incident difficulty with activities of daily living (ADLs), total annual health care costs, and hospitalization rates. Among older adults, 28% reported difficulty and 17% inability to walk 1/4 mile at baseline. Compared to those without difficulty and adjusting for demographics, socioeconomic status, chronic conditions, and health behaviors, mortality was greater in those with difficulty [AOR (95% CI): 1.57 (1.10-2.24)] and inability [AOR (CI): 2.73 (1.79-4.15)]. New functional disability also occurred more frequently as self-reported ability to walk 1/4 mile declined (subsequent incident disability among those with no difficulty, difficulty, or inability to walk 1/4 mile at baseline was 11%, 29%, and 47% for instrumental ADLs, and 4%, 14%, and 23% for basic ADLs). Total annual health care costs were $2773 higher (95% CI $1443-4102) in persons with difficulty and $3919 higher (CI $1948-5890) in those who were unable. For each 100 persons, older adults reporting difficulty walking 1/4 mile at baseline experienced an additional 14 hospitalizations (95% CI 8-20), and those who were unable experienced an additional 22 hospitalizations (CI 14-30) during the follow-up period, compared to persons without walking difficulty. Mobility disability, a simple self-report measure, is a powerful predictor of future health, function, and utilization independent of usual health and demographic indicators. Mobility disability may be used to target high-risk patients for care management and preventive interventions.

Although difficulties with neck mobility often interfere with patients' activities of daily living (ADL) after cervical laminoplasty, there was no detailed study on the relation between the limitations of ADL accompanying postoperative reduced neck mobility and the cervical posterior approach. The aim of this study was to compare retrospectively the frequency of limitations of ADL accompanying neck mobility after laminoplasty preserving the semispinalis cervicis inserted into the C2 spinous process with that after laminoplasty reattaching the muscle to C2. Forty-nine patients after C4-C7 laminoplasty with C3 laminectomy preserving the semispinalis cervicis inserted into C2 (Group A) and 24 patients after C3-C7 laminoplasty reattaching the muscle (Group B) were evaluated. The frequency of postoperative limitations of ADL accompanying each of three neck movements of extension, flexion and rotation were investigated. The postoperative O-C7 angles at extension and flexion was measured on lateral extension and flexion radiographs of the cervical spine, respectively. The postoperative cervical range of motion in rotation was measured in the cranial view using a digital camera. Frequency of limitations of ADL accompanying extension was lower (P = 0.037) in Group A (2%) than in Group B (17%). Frequency of limitations of ADL accompanying flexion was similar in Group A (8%) and Group B (4%). Frequency of limitations of ADL accompanying rotation was lower (P = 0.031) in Group A (12%) than in Group B (33%). Average O-C7 angle at extension was significantly larger (P = 0.002) in Group A (147 degrees ) than in Group B (136 degrees ). Average O-C7 angle at flexion was similar in Group A (93 degrees ) and Group B (91 degrees ). Average range of motion in rotation was significantly larger (P = 0.004) in Group A (110 degrees ) than in Group B (91 degrees ). This retrospective study suggested that the frequency of limitations of ADL accompanying neck extension or rotation was lower after laminoplasty preserving the semispinalis cervicis inserted into C2 than after laminoplasty reattaching the muscle.

Associations between results of post-stroke NDT-Bobath rehabilitation in gait parameters, ADL and hand functions.

In patients after a stroke there are variable disorders. These patients often need rehabilitation in more than one area beceause of multiple limitations of the ability to perform everyday activities. The aim of the study was to assess correlations - statistical relationships between observed gait parameters, ADL and hand functions - results of rehabilitation of patients after ischaemic stroke according to the NDTBobath method for adults. The investigated group consisted of 60 patients after ischaemic stroke, who participated in the rehabilitation programme. 10 sessions of the NDT-Bobath therapy were provided in 2 weeks (10 days of the therapy). The calculation of correlations was made based on changes of parameters: Bobath Scale (to assess hand functions), Barthel Index (to assess ADL), gait velocity, cadence and stride lenght. Measurements were performed in every patient twice: on admission (before the therapy) and after last session of the therapy to assess rehabilitation effects. The main statistically relevant corellations observed in the study were as follows: in the whole group of patients: poor and moderate (negative) correlation between changes of gait parameters and Bobath Scale and Barthel Index, moderate and severe (negative) correlation between changes of gait parameters and Bobath Scale and Barthel Index in the group of women, correlation between changes in Bobath Scale and Barthel Index in the group of patients with left side of paresis, (negative) correlation between changes of gait parameters and Bobath Scale in group of patients younger than 68 years, moderate, high and very high correlations between changes in gait parameters in groups of women, men, younger than 68 years and older than 68 years. There have been observed statistically significant and favourable changes in the health status of patients, described by gait parameters, changes in hand functions and ADL. Based on the presented correlations there is an assumption that it is hard to achieve simultaneous recovery in all areas: gait parameters, hand functions and ADLs in two weeks of rehabilitation.

As the elderly people living alone are enormously increasing recently, we need the system inferring activities of daily living (ADL) for maintaining healthy life and recognizing emergency. The system should be constructed with sensors, which are used to associate with people's living while remaining as non intrusive views as possible. To do this, the proposed system use a triaxial accelerometer sensor and environment sensors indicating contact with subject in home. Particularly, in order to robustly infer ADLs, we present component ADL, which is decided with conjunction of human motion together, not just only contacted object identification. It is an important component in inferring ADL. In special, component ADL decision firstly refines misclassified initial activities, which improves the accuracy of recognizing ADL. Preliminary experiments results for proposed system provides overall recognition rate of over 97% over 8 component ADLs, which can be effectively applicable to recognize the final ADLs.

An increased awareness of patients' and parents' care preferences regarding foot care is desirable from a clinical perspective as such information may be utilised to optimise care delivery. The aim of this study was to examine parents' preferences for, and valuations of foot care and foot-related outcomes in juvenile idiopathic arthritis (JIA). A discrete choice experiment (DCE) incorporating willingness-to-pay (WTP) questions was conducted by surveying 42 parents of children with JIA who were enrolled in a randomised-controlled trial of multidisciplinary foot care at a single UK paediatric rheumatology outpatients department. Attributes explored were: levels of pain; mobility; ability to perform activities of daily living (ADL); waiting time; referral route; and footwear. The DCE was administered at trial baseline. DCE data were analysed using a multinomial-logit-regression model to estimate preferences and relative importance of attributes of foot care. A stated-preference WTP question was presented to estimate parents' monetary valuation of health and service improvements. Every attribute in the DCE was statistically significant (p < 0.01) except that of cost (p = 0.118), suggesting that all attributes, except cost, have an impact on parents' preferences for foot care for their child. The magnitudes of the coefficients indicate that the strength of preference for each attribute was (in descending order): improved ability to perform ADL, reductions in foot pain, improved mobility, improved ability to wear desired footwear, multidisciplinary foot care route, and reduced waiting time. Parents' estimated mean annual WTP for a multidisciplinary foot care service was £1,119.05. In terms of foot care service provision for children with JIA, parents appear to prefer improvements in health outcomes over non-health outcomes and service process attributes. Cost was relatively less important than other attributes suggesting that it does not appear to impact on parents' preferences.

This study examined associations between depressive symptoms and functional capacity, overall dependency in personal activities of daily living (ADLs), and dependency in individual ADL tasks, respectively, in people with a high mean age, large range of functional capacity, and wide spectrum of dependency in ADLs. Cross-sectional data from three studies were used. A total of 392 individuals living in community and residential care facilities were included. Mean age was 86.2 years, 72% were women, 75% were dependent in ADLs, 42% had depression, and 39% had dementia. Depressive symptoms were assessed with the 15-item Geriatric Depression Scale (GDS-15), functional capacity with the Berg Balance Scale (BBS), and ADLs with the Barthel ADL Index. Multiple linear regression analyses with comprehensive adjustments were performed between GDS-15 and BBS, GDS-15 and Barthel ADL Index, and GDS-15 and each individual ADL task, separately. GDS-15 score was associated with BBS score (unstandardized b =-0.03, P=0.008), but not with Barthel ADL Index score (unstandardized b =-0.07, P=0.068). No significant interaction effects of sex, dementia, or living conditions were found in these associations. Among individual ADL tasks, dependency in transfer (unstandardized b =-1.03, P=0.007) and dressing (unstandardized b =-0.70, P=0.035) were associated with depressive symptoms. Functional capacity seems to be independently associated with depressive symptoms in older people living in community and residential care facilities, whereas overall ADL performance may not be associated. Dependency in the individual ADL tasks of transfer and dressing appear to be independently associated with depressive symptoms and may be an important focus of future interdisciplinary multifactorial intervention studies.

To examine the relationship between body mass index (BMI) and subjective well-being (SWB) among long-lived women over 95 years of age and evaluate whether this relationship is mediated by functional ability. Retrospective cohort study. Data from the Rugao longevity cohort, a population-based study in Rugao, China. A sample of 342 long-lived women (mean age 97.4 ± 2.1, range 95-107) whose SWB and other covariates were available were included in this study. BMI was calculated as weight in kilograms divided by height in meters-squared (kg/m(2)). SWB was measured by life satisfaction (LS), positive affect (PA), negative affect (NA) and affect balance (AB). Functional ability was assessed by the Katz Index of Activities of Daily Living (ADL). According to BMI classification standards for China, the underweight group had lower levels of LS than the normal and overweight groups (28.62 vs. 30.51 and 31.57, respectively; p<.05). Correlation analysis showed that BMI was significantly related to LS (r = 0.166, p<.01). The strength of the BMI and LS association was diminished when ADL was included in the general linear regression models. Mediation analysis revealed that ADL mediated this relationship (effect size = 22.6%). We did not observe significant associations of BMI with other SWB components (PA, NA, and AB). For long-lived women, low BMI, rather than elevated BMI, is an indicator of poor psychological well-being. The findings call for public health awareness about low body weight in long-lived women, especially in those with physical disabilities when focusing on quality of life.

A decline in physical capacity takes place with increasing age that negatively affects overall physical function including work ability and the ability to perform typical activities of daily living (ADL). The overall aim of the present study was to determine the neuromuscular adaptations to long-term (1 year) football and strength training in older untrained adults, and to assess the concurrent effect on functional ADL capacity. Twenty-seven healthy elderly males (68.2 ± 3.2 years) were randomly assigned to 12 months of either recreational football training (FT: n = 10), strength training (ST: n = 9) or served as inactive controls (CON: n = 8). Recreational football training consisted of small-sided training sessions whereas strength training consisted of high intensity exercises targeting the lower extremity and upper body. Maximal thigh muscle strength and rate of force development (RFD) were assessed with isokinetic dynamometry, while postural balance and vertical jumping performance were evaluated using force plate analysis. Furthermore, functional ability was evaluated by stair-ascent and chair-rising testing. A total of nine, nine and seven participants from FT, ST and CON, respectively, were included in the analysis. Both exercise regimens led to substantial gains in functional ability, evidenced by 24 and 18 % reduced stair-ascent time, and 32 and 21 % increased chair-rising performance in FT and ST, respectively (all P < 0.05). Long-term strength training led to increased concentric (14 %; P < 0.01) and isometric (23 %; P < 0.001) quadriceps and isometric hamstring strength (44 %; P < 0.0001), whereas football training mainly resulted in enhanced hamstring strength (18 %, P < 0.05) and RFD (89 %, P < 0.0001). Long-term (1 year) strength training led to increased quadriceps and hamstring strength, whereas the adaptations to football training mainly included enhanced strength and rapid force capacity of the hamstring muscles. Gains in functional ability were observed in response to both training regimens, evidenced by reduced stair-ascent time and increased chair-rising performance. Long-term football exercise and strength training both appear to be effective interventional strategies to improve factors of importance for ADL by counteracting the age-related decline in lower limb strength and functional capacity among old male adults. This could potentially be a way to improve work ability of senior workers.

Patients with COPD often experience restriction in their activities of daily living (ADL) due to dyspnea. This type of restriction is unique to patients with COPD and cannot be adequately evaluated by the generic ADL scales. This study developed an ADL scale (the Activity of Daily Living Dyspnea scale [ADL-D scale]) for patients with COPD and investigated its validity and internal consistency. Patients with stable COPD were recruited and completed a pilot 26-item questionnaire. Patients also performed the Incremental Shuttle Walk Test (ISWT), and completed the St George's Respiratory Questionnaire (SGRQ), and Medical Research Council (MRC) dyspnea grade. There were 83 male participants who completed the pilot questionnaire. Following the pilot, 8 items that were not undertaken by the majority of subjects, and 3 items judged to be of low clinical importance by physical therapists were removed from the pilot questionnaire. The final ADL-D scale contained 15 items. Scores obtained with the ADL-D scale were significantly correlated with the MRC dyspnea grades, distance walked on the ISWT and SGRQ scores. The ADL-D scores were significantly different across the five grades of the MRC dyspnea grade. The ADL-D scale showed high consistency (Chronbach's alpha coefficient of 0.96). The ADL-D scale is a useful scale for assessing impairments in ADL in Japanese male patients with COPD.

We aimed to obtain a better understanding of how different aspects of patient functioning affect key cost and caregiver outcomes in Alzheimer's disease (AD). Baseline data from a prospective observational study of community-living AD patients (GERAS) were used. Functioning was assessed using the Alzheimer's Disease Cooperative Study-Activities of Daily Living Scale. Generalized linear models were conducted to analyze the relationship between scores for total activities of daily living (ADL), basic ADL (BADL), instrumental ADL (IADL), ADL subdomains (confirmed through factor analysis) and individual ADL questions, and total societal costs, patient healthcare and social care costs, total and supervision caregiver time, and caregiver burden. Four distinct ADL subdomains were confirmed: basic activities, domestic/household activities, communication, and outside activities. Higher total societal costs were associated with impairments in all aspects of ADL, including all subdomains; patient costs were associated with total ADL and BADL, and basic activities subdomain scores. Both total and supervision caregiver hours were associated with total ADL and IADL scores, and domestic/household and outside activities subdomain scores (greater hours associated with greater functional impairments). There was no association between caregiver burden and BADL or basic activities subdomain scores. The relationship between total ADL, IADL, and the outside activities subdomain and outcomes differed between patients with mild and moderate-to-severe AD. Identification of ADL subdomains may lead to a better understanding of the association between patient function and costs and caregiver outcomes at different stages of AD, in particular the outside activities subdomain within mild AD.

Objectives.  This study examined predisposing, enabling and need variables (Andersen's Behavioral Model) influencing the need for nursing home admission (NHA) in older people receiving home nursing care. In particular, the potential role of coping ability, measured as 'sense of coherence' (SOC), was studied. Design, sample, and measurements.  A survey with baseline- and follow-up data after a 2-year period was undertaken with 208 patients aged 75+. The measures used were: gender, education, age, social visits, SOC, social provision scale (SPS), self-rated health (SRH), general health questionnaire (GHQ), clinical dementia rating (CDR), Barthel activities of daily living (ADL) index, and registered illnesses (RI). A Cox proportional model was used to examine factors that could explain risk of NHA. Results.  Measures with predictive properties were Barthel ADL index, SPS, SRH, and gender. SOC, along with subjective health complaints, general health questionnaire, RI and social visits did not predict NHA. Conclusions.  It is concluded that the patients' subjective evaluations of both their health and perceived social support were important predictors of future NHA needs, and should be seriously taken into consideration, along with the more commonly used objective measures of ADL and CDR. © 2008 The Authors.

[Purpose] This study aimed to cross-cultural adapt and validate the Korean version of an physical activity measure (K-PAM) for community-dwelling elderly. [Subjects and Methods] One hundred and thirty eight community-dwelling elderlies, 32 males and 106 female, participated in the study. All participants were asked to fill out a fifty-one item questionnaire measuring perceived difficulty in the activities of daily living (ADL) for the elderly. One-parameter model of item response theory (Rasch analysis) was applied to determine the construct validity and to inspect item-level psychometric properties of 51 ADL items of the K-PAM. [Results] Person separation reliability (analogous to Cronbach's alpha) for internal consistency was ranging 0.93 to 0.94. A total of 16 items was misfit to the Rasch model. After misfit item deletion, 35 ADL items of the K-PAM were placed in an empirically meaningful hierarchy from easy to hard. The item-person map analysis delineated that the item difficulty was well matched for the elderlies with moderate and low ability except for high ceilings. [Conclusion] Cross-cultural adapted K-PAM was shown to be sufficient for establishing construct validity and stable psychometric properties confirmed by person separation reliability and fit statistics.

Background and purpose Impaired dexterity (fine hand movements) is often present in Parkinson’s disease (PD), even at early to moderate disease stages. It has a detrimental impact on activities of daily living (ADL) such as buttoning, contributing to reduced quality of life. Limb-kinetic apraxia, a loss of the ability to make precise, independent but coordinated finger and hand movements, may contribute to impaired dexterity even more than bradykinesia per se. However, the impact of limb-kinetic apraxia on ADL remains controversial. Our aim was to identify the strongest predictor of buttoning and unbuttoning in PD. It was hypothesized that coin rotation (a surrogate of limb-kinetic apraxia) represents the most important determinant. Methods Sixty-four right-handed, early to moderate PD patients were recruited from three movement disorder centers (Hoehn and Yahr stages 1–3). Buttoning, unbuttoning and coin rotation (right and left hand) represented the target tasks. Motor impairment was assessed according to the Unified Parkinson’s Disease Rating Scale. Results Multiple linear regression analysis showed that coin rotation with the right hand was the only significant predictor of buttoning (P < 0.001) and unbuttoning (P = 0.002). Notably, measures of bradykinesia or overall motor impairment did not represent significant predictors. Conclusions Constituting the novel key finding, limb-kinetic apraxia seems to be particularly relevant for ADL requiring dexterity skills in PD, even at early to moderate disease stages. Our results prompt research into the pathophysiological background and therapeutic options to treat limb-kinetic apraxia. The simple coin rotation test provides valuable information about ADL-related dexterity skills. PMID:27132653

Bio-ontologies are becoming increasingly important in knowledge representation and in the machine learning (ML) fields. This paper presents a ML approach that incorporates bio-ontologies and its application to the SEER-MHOS dataset to discover patterns of patient characteristics that impact the ability to perform activities of daily living (ADLs). Bio-ontologies are used to provide computable knowledge for ML methods to "understand" biomedical data. This retrospective study included 723 cancer patients from the SEER-MHOS dataset. Two ML methods were applied to create predictive models for ADL disabilities for the first year after a patient's cancer diagnosis. The first method is a standard rule learning algorithm; the second is that same algorithm additionally equipped with methods for reasoning with ontologies. The models showed that a patient's race, ethnicity, smoking preference, treatment plan and tumor characteristics including histology, staging, cancer site, and morphology were predictors for ADL performance levels one year after cancer diagnosis. The ontology-guided ML method was more accurate at predicting ADL performance levels (P < 0.1) than methods without ontologies. This study demonstrated that bio-ontologies can be harnessed to provide medical knowledge for ML algorithms. The presented method demonstrates that encoding specific types of hierarchical relationships to guide rule learning is possible, and can be extended to other types of semantic relationships present in biomedical ontologies. The ontology-guided ML method achieved better performance than the method without ontologies. The presented method can also be used to promote the effectiveness and efficiency of ML in healthcare, in which use of background knowledge and consistency with existing clinical expertise is critical.

[Purpose] The purpose of this study was to determine effects of Gross Motor Function Classification System and Manual Ability Classification System levels on performance-based motor skills of children with spastic cerebral palsy. [Subjects and Methods] Twenty-three children with cerebral palsy were included. The Assessment of Motor and Process Skills was used to evaluate performance-based motor skills in daily life. Gross motor function was assessed using Gross Motor Function Classification Systems, and manual function was measured using the Manual Ability Classification System. [Results] Motor skills in daily activities were significantly different on Gross Motor Function Classification System level and Manual Ability Classification System level. According to the results of multiple regression analysis, children categorized as Gross Motor Function Classification System level III scored lower in terms of performance based motor skills than Gross Motor Function Classification System level I children. Also, when analyzed with respect to Manual Ability Classification System level, level II was lower than level I, and level III was lower than level II in terms of performance based motor skills. [Conclusion] The results of this study indicate that performance-based motor skills differ among children categorized based on Gross Motor Function Classification System and Manual Ability Classification System levels of cerebral palsy.

Powered AFO for Achilles tendon rupture.

PubMed

Yoshizawa, Nobuyuki

2008-01-01

This paper proposes a powered ankle foot orthosis (AFO) for the treatment of a ruptured Achilles tendon. Usually, conservative orthosis treatment requires about two months, and a motionless ankle degrades activities of daily living (ADL). It is difficult to go to school or work on foot, and a pair of crutches is needed to go up and down stairs. In order to improve the ADL, an electric powered AFO has been designed to improve the ability to walk with a fixed ankle joint. The sole of the proposed AFO is equipped with an electric actuator. The prototype actuator consists of Nd magnets and electromagnets and is lightweight and battery driven. The actuator can switch the upright posture and the stepped forward posture of the patient. In an experiment, the use of this electric AFO made it possible to walk and to ascend and descend stairs with a fixed ankle joint.

Up to 40% of women over 70 years with primary operable breast cancer in the UK are treated with primary endocrine therapy (PET) as an alternative to surgery. A variety of factors are important in determining treatment for older breast cancer patients. This study aimed to identify the patient and tumor factors associated with treatment allocation in this population. Prospectively collected data on treatment received (surgery vs. PET) were analysed with multivariable logistic regression using the variables age, modified Charlson Comorbidity Index (CCI), activities of daily living (ADL) score, Mini-Mental State Examination (MMSE) score, HER2 status, tumour size, grade and nodal status. Data were available for 1,122 cancers in 1,098 patients recruited between February 2013 and June 2015 from 51 UK hospitals. About 78% of the population were treated surgically, with the remainder being treated with PET. Increasing patient age at diagnosis, increasing CCI score, large tumor size (5 cm or more) and dependence in one or more ADL categories were all strongly associated with non-surgical treatment (P<0.05). Increasing comorbidity, large tumor size and reduced functional ability are associated with reduced likelihood of surgical treatment of breast cancer in older patients. However, age itself remains a significant factor for non-surgical treatment; reinforcing the need for evidence-based guidelines.

ABSTRACT Background Mobility, such as walking 1/4 mile, is a valuable but underutilized health indicator among older adults. For mobility to be successfully integrated into clinical practice and health policy, an easily assessed marker that predicts subsequent health outcomes is required. Objective To determine the association between mobility, defined as self-reported ability to walk 1/4 mile, and mortality, functional decline, and health care utilization and costs during the subsequent year. Design Analysis of longitudinal data from the 2003–2004 Medicare Current Beneficiary Survey, a nationally representative sample of Medicare beneficiaries. Participants Participants comprised 5895 community-dwelling adults aged 65 years or older enrolled in Medicare. Main Measures Mobility (self-reported ability to walk 1/4 mile), mortality, incident difficulty with activities of daily living (ADLs), total annual health care costs, and hospitalization rates. Key Results Among older adults, 28% reported difficulty and 17% inability to walk 1/4 mile at baseline. Compared to those without difficulty and adjusting for demographics, socioeconomic status, chronic conditions, and health behaviors, mortality was greater in those with difficulty [AOR (95% CI): 1.57 (1.10-2.24)] and inability [AOR (CI): 2.73 (1.79-4.15)]. New functional disability also occurred more frequently as self-reported ability to walk 1/4 mile declined (subsequent incident disability among those with no difficulty, difficulty, or inability to walk 1/4 mile at baseline was 11%, 29%, and 47% for instrumental ADLs, and 4%, 14%, and 23% for basic ADLs). Total annual health care costs were $2773 higher (95% CI $1443-4102) in persons with difficulty and $3919 higher (CI $1948-5890) in those who were unable. For each 100 persons, older adults reporting difficulty walking 1/4 mile at baseline experienced an additional 14 hospitalizations (95% CI 8-20), and those who were unable experienced an additional 22 hospitalizations (CI 14-30) during the follow-up period, compared to persons without walking difficulty. Conclusions Mobility disability, a simple self-report measure, is a powerful predictor of future health, function, and utilization independent of usual health and demographic indicators. Mobility disability may be used to target high-risk patients for care management and preventive interventions. PMID:20972641

We retrospectively evaluated the effectiveness of prolotherapy in resolving pain, stiffness, and crepitus, and improving physical activity in consecutive chondromalacia patients from February 2008 to September 2009. Sixty-nine knees that received prolotherapy in 61 patients (33 female and 36 male) who were 18–82 years old (average, 47.2 years) were enrolled. Patients received 24 prolotherapy injections (15% dextrose, 0.1% procaine, and 10% sarapin) with a total of 40 cc in the anterior knee. At least 6 weeks after their last prolotherapy session, patients provided self-evaluation of knee pain upon rest, activities of daily living (ADL) and exercise, range of motion (ROM), stiffness, and crepitus. Symptom severity, sustained improvement of symptoms, number of pain pills needed, and patient satisfaction before treatment and improvement after treatment were recorded. Following prolotherapy, patients experienced statistically significant decreases in pain at rest, during ADL, and exercise. Stiffness and crepitus decreased after prolotherapy, and ROM increased. Patients reported improved walking ability and exercise ability after prolotherapy. For daily pain level, ROM, daily stiffness, crepitus, and walking and exercise ability, sustained improvement of over 75% was reported by 85% of patients. Fewer patients required pain medication. No side effects of prolotherapy were noted. The average length of time from last prolotherapy session was 14.7 months (range, 6 months to 8 years). Only 3 of 16 knees were still recommended for surgery after prolotherapy. Prolotherapy ameliorates chondromalacia patella symptoms and improves physical ability. Patients experience long-term improvement without requiring pain medications. Prolotherapy should be considered a first-line, conservative therapy for chondromalacia patella. PMID:24596471

There is an increasing interest in cognitive and functional outcomes in the respective stages of Alzheimer's disease (AD) and in novel therapies particularly for the milder phases of AD. Our aim was to describe and compare various aspects of disease progression in patients with mild versus moderate AD in routine clinical practice of cholinesterase inhibitor (ChEI) therapy. This 3-year, prospective, observational, multicentre study included 1021 participants. Of these, 734 had mild AD (Mini-Mental State Examination (MMSE) score, 20-26) and 287 had moderate AD (MMSE score, 10-19) at the start of ChEI treatment. At baseline and every 6 months, patients were assessed using cognitive, global, instrumental and basic activities of daily living (ADL) scales. Potential predictors of deterioration in moderate AD were analysed using mixed-effects models. The change from baseline between participants with mild and moderate stages of AD after 3 years of ChEI therapy differed significantly on the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) and basic ADL, but not using the MMSE and instrumental ADL scales. Protective independent factors for better cognitive long-term outcome in the group with moderate AD were older age, higher instrumental ADL ability, no antipsychotics, usage of non-steroidal anti-inflammatory drugs/acetylsalicylic acid, living with family member, lower education and a higher mean dose of ChEI. Apolipoprotein E genotype did not influence the rates of disease progression or the longitudinal outcomes. Prediction models were provided for moderate AD. More sensitive cognitive measures, such as the ADAS-cog scale, are required to detect a possibly faster deterioration among the participants with moderate AD. This study highlighted the clinical importance of instrumental ADL evaluations in patients at a mild stage of AD, and the importance of optimizing the ChEI dose even for individuals with moderate AD. Solitary living was a risk factor for faster cognitive decline, and probably expanded the need for formal care in the group with moderate AD. The patients with more advanced AD and presumably more pronounced neuroinflammation might have additional cognitive benefits from longer-term treatment with anti-inflammatory drugs.

To compare the ability of the Short Physical Performance Battery (SPPB), 4-m walk test (4mWT), 6-minute walk test (6MWT), and handgrip strength to predict mortality, incident disability, worsening mobility, and falls in older community dwellers. Cohort study. Population-based. Individuals aged 65 and older n = 561) without prevalent basic activity of daily living (ADL) disability participating. Separate logistic regression models were developed to predict incident ADL disability, worsening mobility, and falls in 3 years, and Cox regression models were used to assess 7-year risk of death as a function of the four tests, adjusting for covariates. Performance tests were reciprocally correlated at baseline. After 3 years, 33 (7.3%) of 453 participants reexamined were disabled in ADLs, 87 (20%) had worsening mobility, and 99 (22%) reported falls. Of the 561 baseline participants, 141 (25%) died over the 7 years. All measures predicted incident ADL disability, with adjusted odds ratios (ORs) per unit increase of 0.85 (95% confidence interval (CI) = 0.77-0.93) for handgrip strength, 0.08 (95% CI = 0.02-0.36) for 4mWT, 0.74 (95% CI = 0.61-0.89) for SPPB, and 0.993 (95% CI = 0.988-0.997) for 6MWT. Handgrip strength (OR = 0.88, 95% CI = 0.83-0.93), 4mWT (OR = 0.33, 95% CI = 0.11-0.94), and SPPB (OR = 0.81, 95%CI = 0.71-0.93) predicted worsening mobility. No measure predicted falls; only SPPB (hazard ratio (HR) = 0.92, 95% CI = 0.85-0.997) and 6MWT (HR = 0.997, 95% CI = 0.995-0.999) predicted death. Performance measures are independent predictors of relevant health outcomes, with the exception of falls. Because SPPB is easily applied and is the only measure predicting incident ADL disability, worsening mobility, and death, it is preferable to the other tests. © 2015, Copyright the Authors Journal compilation © 2015, The American Geriatrics Society.

To assess impact of premenstrual symptoms on activities of women's daily lives (ADL). Cross-sectional population-based survey. Market research company. A total of 4,085 women aged 14-50 years recruited by random telephone digit dialing in France, Germany, Hungary, Italy, Spain, the United Kingdom, Brazil, and Mexico. None. A telephone interview checklist of 23 premenstrual symptoms, sociodemographic and lifestyle variables, and ADL effects (global question and seven areas). Stepwise regression measured the effect of premenstrual symptoms and sociodemographic factors on ADL. Symptoms and symptom domains (physical and mental) had similar negative effects on ADL. Activities of daily life were predominantly affected by symptom severity. Income level, age, and country also significantly affected ADL. In all, 2,638 women (64.6%) were minimally affected in ADL, 981 (24%) were moderately affected, and 454 (11.1%) were severely affected. Both physical and mental premenstrual symptoms have significant impact on quality of life, assessed as ADL. Up to 35% of women of reproductive age in Europe and Latin America were moderately or severely affected in ADL by cyclical premenstrual symptoms.

N,N-diethyl-4-(5-hydroxyspiro[chromene-2,4′-piperidine]-4-yl) benzamide (ADL5859) and N,N-diethyl-3-hydroxy-4-(spiro[chromene-2,4′-piperidine]-4-yl)benzamide (ADL5747) are novel δ-opioid agonists that show good oral bioavailability and analgesic and antidepressive effects in the rat and represent potential drugs for chronic pain treatment. Here, we used genetic approaches to investigate molecular mechanisms underlying their analgesic effects in the mouse. We tested analgesic effects of ADL5859 and ADL5747 in mice by using mechanical sensitivity measures in both complete Freund's adjuvant and sciatic nerve ligation pain models. We examined their analgesic effects in δ-opioid receptor constitutive knockout (KO) mice and mice with a conditional deletion of δ-receptor in peripheral voltage-gated sodium channel (Nav)1.8-expressing neurons (cKO mice). Both ADL5859 and ADL5747, and the prototypical δ agonist 4-[(R)-[(2S,5R)-4-allyl-2,5-dimethyl-piperazin-1-yl]-(3-methoxyphenyl)methyl]-N,N-diethyl-benzamide (SNC80) as a control, significantly reduced inflammatory and neuropathic pain. The antiallodynic effects of all three δ-opioid agonists were abolished in constitutive δ-receptor KO mice and strongly diminished in δ-receptor cKO mice. We also measured two other well described effects of δ agonists, increase in locomotor activity and agonist-induced receptor internalization by using knock-in mice expressing enhanced green fluorescence protein-tagged δ receptors. In contrast to SNC80, ADL5859 and ADL5747 did not induce either hyperlocomotion or receptor internalization in vivo. In conclusion, both ADL5859 and ADL5747 showed efficient pain-reducing properties in the two models of chronic pain. Their effects were mediated by δ-opioid receptors, with a main contribution of receptors expressed on peripheral Nav1.8-positive neurons. The lack of in vivo receptor internalization and locomotor activation, typically induced by SNC80, suggests agonist-biased activity at the receptor for the two drugs. PMID:22700431

Infliximab (IFX) and adalimumab (ADL) drug levels and anti-drug antibodies (ADA) are assessed using a variety of techniques, therefore, results cannot accurately be compared for clinical purposes. The aim of this study was to test two infliximab (IFX) and adalimumab (ADL) ELISA versions, for drug levels and ADA, to see whether they yield similar results. ELISA versions [Promonitor® IFX R1 and R2 (V.1), Promonitor® IFX and Anti-IFX (V.2); Promonitor® ADL R1 and R2 (V.1), Promonitor® ADL and Anti-ADL (V.2) kits (Progenika Biopharma, Spain)] were used to measure drug levels and ADA in IFX (n=24) and ADL (n=24) rheumatoid arthritis-treated patients in three independent laboratories. Quantitative and qualitative agreements were evaluated using intraclass correlation coefficients (ICC), and Cohen's Kappa (κ) respectively. The Bland-Altman plots assessed differences between V.1 and V.2. Interlaboratory agreement (ICC/κ) with V.1 was poor for IFX (0.66/0.62) and ADL (0.69/0.52) drug levels; meanwhile, high agreement was found with V.2 for IFX (0.98/0.95) and ADL (0.094/1.00). Comparison between V.1 and V.2 in each laboratory resulted in systematically higher values in V.2 than in V.1 and poor agreement (ICC/κ ranges) for IFX (0.12-0.7/ 0.19-0.42) and ADL (0.69-0.89 /0.50-0.73). Qualitative measurements result in better agreement, as evidenced in our study. Greater agreement in V.2 compared with V.1 for IFX and ADL levels could be due to a better tune up. Further studies are required to standardise methods to establish therapeutic reference ranges.

Greater Independence in Activities of Daily Living is Associated with Higher Health-Related Quality of Life Scores in Nursing Home Residents with Dementia

Health-related quality of life (HRQL) for nursing home residents is important, however, the concept of quality of life is broad, encompasses many domains and is difficult to assess in people with dementia. Basic activities of daily living (ADL) are measured routinely in nursing homes using the Resident Assessment Instrument-Minimum Data Set Version 2.0 (RAI-MDS) and Functional Independence Measure (FIM) instrument. We examined the relationship between HRQL and ADL to assess the future possibility of ADL dependency level serving as a surrogate measure of HRQL in residents with dementia. To assess ADL, measures derived from the RAI-MDS and FIM data were gathered for 111 residents at the beginning of our study and at 6-month follow-up. Higher scores for independence in ADL were correlated with higher scores for a disease-specific HRQL measure, the Quality of Life—Alzheimer’s Disease Scale. Preliminary evidence suggests that FIM-assessed ADL is associated with HRQL for these residents. The associations of the dressing and toileting items with HRQL were particularly strong. This finding suggests the importance of ADL function in HRQL. The RAI-MDS ADL scales should be used with caution to evaluate HRQL. PMID:27417776

To explore relationships between family quality of life, day occupations and activities of daily living (ADL) of young persons with Down syndrome. Data were collected from 150 families with a young person with Down syndrome aged 16-30 years participating in the Down syndrome "Needs Opinions Wishes" database. Data described the young person's characteristics (including functional abilities, behaviour and day occupations) and family characteristics (including income, family and community supports and quality of life). Compared to families of young people attending open employment, families of young people participating in sheltered employment tended to report poorer family quality of life, after adjusting for personal characteristics, behaviour and income (coeff -6.78, 95 % CI -14.38, 0.81). Family supports reduced this relationship (coeff -6.00, 95 % CI -12.76, 0.76). Families of young people with greater functioning in ADL reported better family quality of life regardless of personal and environmental factors (coeff 0.45, 95 % CI 0.05, 0.85) and inclusion of family factors such as family supports reduced this association (coeff 0.29, 95 % CI -0.10, 0.67). Participation of young people with Down syndrome in open employment may positively influence family quality of life. Services that facilitate functioning in ADL and assist the families in accessing suitable family supports have the potential to positively influence family quality of life.

The aim of this study was to verify the effectiveness and efficacy of saving time and reducing burden for patients, nurses, and even occupational therapists through computer adaptive testing (CAT). Based on an item bank of the Barthel Index (BI) and the Frenchay Activities Index (FAI) for assessing comprehensive activities of daily living (ADL) function in stroke patients, we developed a visual basic application (VBA)-Excel CAT module, and (1) investigated whether the averaged test length via CAT is shorter than that of the traditional all-item-answered non-adaptive testing (NAT) approach through simulation, (2) illustrated the CAT multimedia on a tablet PC showing data collection and response errors of ADL clinical functional measures in stroke patients, and (3) demonstrated the quality control of endorsing scale with fit statistics to detect responding errors, which will be further immediately reconfirmed by technicians once patient ends the CAT assessment. The results show that endorsed items could be shorter on CAT (M = 13.42) than on NAT (M = 23) at 41.64% efficiency in test length. However, averaged ability estimations reveal insignificant differences between CAT and NAT. This study found that mobile nursing services, placed at the bedsides of patients could, through the programmed VBA-Excel CAT module, reduce the burden to patients and save time, more so than the traditional NAT paper-and-pencil testing appraisals.

Disease- or age-related neuropsychiatric symptoms and cognitive and chronobiological impairments greatly aggravate the activities of daily living (ADL) in patients. The present study evaluates the effects of aniracetam on a decline in mealtime-associated anticipatory behavior in aged rats, as an animal model of temporally regulated behaviors or habitual daily activities. Aged rats showed a lower but typical nocturnal motor activity rhythm than young rats when the animals were fed ad lib. Mealtime-associated anticipatory behavior emerged in young rats when the rats were fed at a fixed time for 6 days, but the activity in aged rats was diminished. Repeated administration of aniracetam (100 mg/kg PO) or physostigmine (0.1 mg/kg SC) for 7 days ameliorated the impaired anticipatory behavior in aged rats. Nefiracetam (10 mg/kg PO) was ineffective. All compounds tested had no effect on appetite or motor ability. These results indicate that aging disturbs the timing or temporal regulation of anticipatory behavior, probably resulting from dysfunction in a food-entrainable oscillator linked to central cholinergic systems. The restoration of the time-keeping ability by aniracetam may be mediated by the facilitation of reticulothalamic cholinergic neurotransmission, and the action may lead to the improvement of declined ADL in stroke patients.

Purpose of the Study: In examining the ability of resilience, or the ability to navigate adversity in a manner that protects well-being, to buffer the impact of chronic disease onset on disability in later life, the authors tested 2 hypotheses: (a) People with greater levels of resilience will have lower levels of disability and (b) resilience will moderate the association between the onset of a new chronic condition and subsequent disability. Design and Methods: This study used a sample of 10,753 Americans between the ages of 51 and 98, derived from 3 waves of the Health and Retirement Study (2006–2010). Ordinary least squares regression was used to estimate the impact of resilience on changes in disability (measured as difficulty with activities of daily living [ADLs] and instrumental activities of daily living [IADLs]) over a 2-year period using a simplified resilience score. Results: Resilience protects against increases in ADL and IADL limitations that are often associated with aging. Resilience mitigates a considerable amount of the deleterious consequences related to the onset of chronic illness and subsequent disability. Implications: Our results support our hypotheses and are consistent with claims that high levels of resilience can protect against the negative impact of disability in later life. PMID:25063353

Neurological symptom severity is a prognostic factor for post-stroke activities of daily living (ADL). Recently, it has been reported that white matter lesions indicate poor functional prognosis in patients with stroke. The present study investigated the influence of white matter lesions on the ADL of older patients with stroke who have mild neurological symptoms. We investigated ADL at discharge in 44 patients with stroke (men, n = 27; women, n = 17; mean age 78 years [range 71-85 years]) aged ≥65 years with National Institutes of Health Stroke Scale scores of ≤5 (cerebral infarction, n = 37; cerebral hemorrhage, n = 7). We used single correlation analysis and multiple regression analysis to investigate factors that correlated with ADL at discharge. ADL at discharge was also evaluated on the basis of white matter lesion severity (Fazekas classification, grades 0-3). Single correlation analysis showed that age (r = -0.36, P = 0.016), male sex (r = 0.362, P = 0.016), neurological symptom severity (r = -0.361, P = 0.016), ADL on starting rehabilitation (r = 0.685, P < 0.001) and white matter lesion severity (r = -0.361, P = 0.016) significantly correlated with ADL at discharge. Multiple regression analysis showed that ADL on starting rehabilitation (β = 0.519, t = 4.723, P < 0.001) and white matter lesion severity (β = -0.309, t = -3.057, P < 0.01) were statistically significant prognostic factors for ADL at discharge. ADL at discharge score was significantly lower in the group with high white matter lesion severity (Fazekas, grade 2) than in the other two groups (Fazekas, grade 0, P < 0.01; Fazekas, grade 1, P < 0.05). Severe white matter lesions are a prognostic factor for poor ADL at discharge in older patients with stroke who have mild neurological symptoms.

Objectives To determine the relationship between long-term change in activities of daily living (ADL) and falls in the elderly and to identify characteristics of groups at risk for falls. Methods This was a 6-year, prospective cohort study using data from the Good Aging in Skåne study in southern Sweden, involving 1,540 elderly subjects, including the oldest-old (age, 60–93 years). The subjects were recruited from the general population. ADL was measured at a baseline and follow-up assessment, using Sonn and Åsberg’s revised scale and the ADL staircase. Falls were recorded in a period of 6 months before the follow-up assessment. The association between falls and change in ADL was calculated using adjusted, multiple logistic regression analysis and presented in odds ratios (ORs). Results Thirteen percent of the study population reported one or several falls in the measured period. Over the course of 6 years, one in four participants changed their ADL status, and parts of this category had an increased risk for falls compared with those who stayed independent in ADL or who had no change in the ADL staircase. Groups with different characteristics had a prominent risk for falls: those with a reduction of two to eight steps in the ADL staircase (OR, 4.05; 95% confidence interval [CI], 1.62–10.11) and those becoming independent from dependency in instrumental ADL (OR, 4.13; 95% CI, 1.89–9.00). The former group had advanced age with a greater burden of cognitive impairment, gait disability, arrhythmia, and fall risk medications. The latter group had a higher prevalence of ischemic heart disease and low walking speed. Conclusion Both deterioration and improvement in ADL over the course of 6 years increased the risk for falls in a general elderly population. Interventional efforts may require different strategies, as groups with different characteristics were at risk. Those at risk with improved ADL function may have a history of sufficient burden of comorbidity combined with obtained mobility for exposure to a fall event. PMID:25378916

although recent studies have suggested that inflammation may play an important role in the process of ageing and in the development of disabilities, knowledge about the role of inflammation in physical performance decline among middle-aged and older people in the context of developing countries is limited. to examine the association between C-reactive protein (CRP) and the activities of daily living (ADL) among middle-aged (40-54 years old) and older (55-96 years old) people in Indonesia. data from a population-based sample, the Indonesia Family Life Survey (IFLS) 2007, were analysed. The data consist of 1,702 respondents of middle age (40-54 years old) and 2,017 older respondents who had completed information on ADL and CRP. CRP concentrations in Dried Blood Spot (DBS) specimens were measured, using the validated enzyme-linked immunosorbent assay (ELISA) method. Thirteen items of ADL were used to measure physical performance. A three-level linear model was applied to take advantage of the nested structure of data at the individual level within the household and community levels. high levels of CRP were significantly associated with lower ADL for middle-aged and older people (P < 0.001). The model was adjusted for co-morbid conditions, health risk factors, medications, depressive symptoms and sociodemographic characteristics. the significant association between the high level of CRP and lower ADL among older people in Indonesia is in line with earlier studies in the context of developed countries. This study provides an extension in which the significant association was also found in middle-aged people (40-54 years old). © The Author 2015.

Hammar, Teija; Perälä, Marja-Leena; Rissanen, Pekka

2009-03-01

The aim of the study was to compare clients' and named home care (HC) workers' perceptions of clients' functional ability (FA) and need for help and to analyse which client- and municipality-related factors are associated with perceptions of client's FA. The total of 686 Finnish HC clients was interviewed in 2001. Further, the questionnaire was sent to 686 HC workers. FA was assessed by activities of daily living (ADL), which included both basic/physical (PADL) and instrumental (IADL) activities. The association between client's FA and municipality-related variables was analysed by using hierarchical logistic regression models. The findings indicated that clients' and HC-workers' perceptions about what the clients were able to do were similar in the PADL functions, but perceptions differed when it comes to the IADL functions for mobility and in climbing stairs. A smaller proportion of clients compared with HC workers assessed themselves to be in need of help in all ADL functions. Use of home help and bathing services increased the probability of belonging to the 'poor' FA class while living alone and small size of municipality decreased the probability. The study indicates that although clients and workers assessed client's FA fairly similarly, there were major differences in perceptions concerning clients' needs for help in ADL functions. Clients' and workers' shared view of need for help forms a basis for high-quality care. Therefore, the perception of both the clients and workers must be taken into account when planning care and services. There was also variation in clients' FA between municipalities, although only the size of municipality had some association with the variation. The probability that clients with a lower FA are cared for in HC is higher if the clients live in large- rather than small-sized municipalities. This may reflect a better mix of services and resources in large-sized municipalities.

There is evidence that physical activity (PA) is of cognitive benefit to the ageing brain, but little is known on the effect in patients with Alzheimer's disease (AD). The present pilot study assessed the effect of a home-based PA training on clinical symptoms, functional abilities, and caregiver burden after 12 and 24 weeks. In an RCT thirty patients (aged 72.4±4.3 years) with AD (MMSE: 20.6±6.5 points) and their family caregivers were allocated to a home-based 12-week PA intervention program or the usual care group. The program changed between passive, motor-assisted or active resistive leg training and changes in direction on a movement trainer in order to combine physical and cognitive stimuli. Analysis of activities of daily living in the patients (ADCS ADL total score) revealed a significant group × time interaction effect (95% CI of the difference between both groups at T2: 5.01-10.51). The control group experienced decreases in ADL performance at week 12 and 24 whereas patients in the intervention group remained stable. Analyses of executive function and language ability revealed considerable effects for semantic word fluency with a group × time interaction (95% CI of the difference between both groups at T2: 0.18-4.02). Patients in the intervention group improved during the intervention and returned to initial performance at week 12 whereas the controls revealed continuous worsening. Analyses of reaction time, hand-eye quickness and attention revealed improvement only in the intervention group. Caregiver burden remained stable in the intervention group but worsened in the control group. This study suggests that PA in a home-based setting might be an effective and intrinsically attractive way to promote PA training in AD and modulate caregiver burden. The results demonstrate transfer benefits to ADL, cognitive and physical skill in patients with AD. ClinicalTrials.gov NCT02196545.

2017-07-05

We studied children and adolescents with symbrachydactyly to determine whether hand function depends on digit opposability and whether scores for function and quality-of-life measures differ from population norms. Participants were grouped on the basis of hand morphology: Group A lacked opposable digits, and Group B had ≥2 digits that were opposable. The groups were compared with each other and with norms with respect to pinch strength, the performance of bimanual activities and in-hand manipulation, and questionnaires regarding psychosocial status and the ability to perform activities of daily living (ADLs). Participants and parents also rated the appearance and function of the hand. Pinch strength was higher for participants in Group B (4.1 compared with 2.4 kg; p = 0.008), but the groups did not differ with respect to the proportion of participants outside of pinch norms. Participants in Group B were more likely to actively use their affected hand to perform bimanual activities (p ≤ 0.0009), and to use normal or supination strategies to accomplish in-hand manipulation (p = 0.031). The groups did not differ in the proportion of ADLs rated "difficult" or "impossible," and both groups tested within normal limits for psychosocial function. Participants from both groups and their parents rated their satisfaction with hand appearance and function similarly high. Participants with ≥2 opposable digits incorporated their hand better in bimanual activities and used more effective strategies to accomplish in-hand manipulation than those who did not. These groups reported no difference in the ability to perform ADLs or with psychosocial function, which was within the normal range. Children and adolescents with symbrachydactyly demonstrated and reported a high level of function in all domains of validated function tests. This study provides information to help parents of children with a unilateral hand malformation understand their child's potential function, and assist surgeons with recommending treatment.

Unsupervised machine-learning method for improving the performance of ambulatory fall-detection systems

PubMed Central

2012-01-01

Background Falls can cause trauma, disability and death among older people. Ambulatory accelerometer devices are currently capable of detecting falls in a controlled environment. However, research suggests that most current approaches can tend to have insufficient sensitivity and specificity in non-laboratory environments, in part because impacts can be experienced as part of ordinary daily living activities. Method We used a waist-worn wireless tri-axial accelerometer combined with digital signal processing, clustering and neural network classifiers. The method includes the application of Discrete Wavelet Transform, Regrouping Particle Swarm Optimization, Gaussian Distribution of Clustered Knowledge and an ensemble of classifiers including a multilayer perceptron and Augmented Radial Basis Function (ARBF) neural networks. Results Preliminary testing with 8 healthy individuals in a home environment yields 98.6% sensitivity to falls and 99.6% specificity for routine Activities of Daily Living (ADL) data. Single ARB and MLP classifiers were compared with a combined classifier. The combined classifier offers the greatest sensitivity, with a slight reduction in specificity for routine ADL and an increased specificity for exercise activities. In preliminary tests, the approach achieves 100% sensitivity on in-group falls, 97.65% on out-group falls, 99.33% specificity on routine ADL, and 96.59% specificity on exercise ADL. Conclusion The pre-processing and feature-extraction steps appear to simplify the signal while successfully extracting the essential features that are required to characterize a fall. The results suggest this combination of classifiers can perform better than MLP alone. Preliminary testing suggests these methods may be useful for researchers who are attempting to improve the performance of ambulatory fall-detection systems. PMID:22336100

The outcome and functional trajectory of older persons admitted to intensive care (ICU) unit remain a true question for critical care physicians and geriatricians, due to the heterogeneity of geriatric population, heterogeneity of practices and absence of guidelines. To describe the 1-year outcome, prognosis factors and functional trajectory for older people admitted to ICU. In a prospective 1-year cohort study, all patients aged 75 years and over admitted to our ICU were included according to a global comprehensive geriatric assessment. Follow-up was conducted for 1 year survivors, in particular, ability scores and living conditions. Of 188 patients included [aged 82.3 ± 4.7 years, 46% of admissions, median SAPS II 53.5 (43-74), ADL of Katz's score 4.2 ± 1.6, median Barthel's index 71 (55-90), AGGIR scale 4.5 ± 1.5], the ICU, hospital and 1-year mortality were, respectively, 34, 42.5 and 65.5%. Prognosis factors were: SAPS 2, mechanical ventilation, comorbidity (Lee's and Mc Cabe's scores), disability scores (ADL of Katz's score, Barthel's index and AGGIR scale), admission creatinin, hypoalbuminemia, malignant haemopathy, cognitive impairment. One-year survivors lived in their own home for 83%, with a preserved physical ability, without significant variation of the three ability assessed scores compared to prior ICU admission. The mortality of older people admitted to ICU is high, with a significant impact of disabilty scores, and preserved 1-year survivor independency. Other studies, including a better comprehensive geriatric assessment, seem necessary to determine a predictive "phenotype" of survival with a "satisfactory" level of autonomy.

To examine effects of physical and geriatric rehabilitation on institutionalisation and mortality after hip fracture. Prospective randomised study. Physically oriented (187 patients), geriatrically oriented (171 patients), and health centre hospital rehabilitation (180 patients, control group). A total of 538 consecutively, independently living patients with non-pathological hip fracture. Patients were evaluated on admission, at 4 and 12 months for social status, residential status, walking ability, use of walking aids, pain in the hip, activities of daily living (ADL) and mortality. Mortality was significantly lower at 4 and 12 months in physical rehabilitation (3.2%, 8.6%) than in geriatric rehabilitation group (9.6%, 18.7%, P=0.026, P=0.005, respectively) or control group (10.6%, 19.4%, P=0.006, P=0.004, respectively). At 4 months more patients in physical (84.4%) and geriatric rehabilitation group (78.0%) were able to live at home or sheltered housing than in control group (71.9%, P=0.0012 and P<0.001, respectively). No significant difference was found between physical rehabilitation and geriatric rehabilitation (P=0.278). Analysis of femoral neck and trochanteric fractures showed that significant difference was true only for femoral neck fractures (physical rehabilitation vs geriatric rehabilitation P=0.308, physical rehabilitation vs control group P<0,001 and geriatric rehabilitation vs control group P<0.001). Effects of intensified rehabilitations disappeared at 12 months. No impact on walking ability or ADL functions was observed. Physical rehabilitation reduced mortality. Physical and geriatric rehabilitation significantly improved the ability of independent living after 4 months especially among the femoral neck fracture patients but this effect could not be seen after 12 months. © The Author(s) 2014.

To examine the physical, mental, and cognitive function of centenarians. Descriptive study using a structured questionnaire and convenience sampling. Residential care facilities and private dwellings in Australia. A convenience sample of 188 centenarians. The Hospital Anxiety and Depression Scale (HADS) screened for anxiety and depression. The Katz Index of Independence in Activities of Daily Living (Katz ADL) was used to assess functional status. The Quality of Life Scale was used to assess quality of life. The Mini-Mental State Examination (MMSE) was used to screen for dementia. Structured responses were obtained for living arrangement, marital status, social relationships, and supports. Centenarians had regular contact with friends (59%), neighbors (62%), and families (72%); 54% were religious and 43.5% had received social supports. Average MMSE and Katz ADL scores were 21.5 and 3.7, respectively; 45% had scores on the MMSE indicative of dementia, 10% indicated anxiety and 14% depression on the HADS. Participants with poor ratings of health experienced higher rates of anxiety and depression than their healthier counterparts. In this convenience sample of Australian centenarians, anxiety and depression was relatively nonexistent, and most reported a high quality of life. This was despite objective deterioration in functional status, paralleling the aging process, and high dependence on others for everyday tasks. Potentially, this is suggestive of a unique ability within the sample to adapt to aging and its limitations. © 2011, Copyright the Authors.

Certain patients with critical limb ischemia (CLI) experience significant decline in activities of daily living (ADL) during hospitalization. The prognosis of decline in ADL during hospitalization remains unknown. A retrospective analysis was performed on collected data of patients with CLI treated by endovascular treatment between April 2007 and December 2015. We evaluated CLI in patients ADL at the time of hospitalization and after discharge using the Barthel index. We classified all patients into patients with decline in ADL and stable in ADL and compared clinical outcomes (cumulative incidence of wound healing, amputation-free survival at 1 year) between the 2 groups. Two hundred and fifty-five consecutive patients with CLI (221 limbs), who underwent successful endovascular intervention, were enrolled in this study. Of all patients, 22 patients were classified into the decline group. The prevalence of wound, Ischemia, foot infection (WIfI) classification high grade was higher in the decline group (30.7% vs 63.6%; P < .01). The wound healing rates were worse in the decline group than in the stable group (40% vs 78% at 1 year; P < .01). The same trends were observed in the amputation-free survival (37% vs 78%; P < .01). After multivariate analysis, decline in ADL was an independent predictor of wound healing and amputation-free survival (odds ratio [OR]: 2.85, 95% confidence interval [CI]: 1.61-3.35, P < .01; OR: 2.46, 95% CI: 1.26-4.53, P = .01). Patients with CLI with decline in ADL during hospitalization were found to have a poor prognosis suggesting that a decline in ADL may affect the clinical outcomes.

Mechanical ventilation (MV) is imperative in many forms of acute respiratory failure (ARF) in COPD patients. Previous studies have shown the difficulty to identify parameters predicting the outcome of COPD patients treated by invasive MV. Our hypothesis was that a non specialized score as the activities daily living (ADL) score may help to predict the outcome of these patients. We studied the outcome of 25 COPD patients admitted to the intensive care unit for ARF requiring invasive MV. The patients were divided into those weaning success (group A n = 17, 68%) or failure (group B n = 8, 32%). We investigated the correlation between the ADL score and the outcome and mortality. The ADL score was higher in group A (5.1 ±1.1 vs 3.7 ± 0.7 in group B, p < 0.01). Weaning was achieved in 76.5% of the cases with an ADL score ≥ 4 and in 23.5% of the cases with an ADL score < 4 (p < 0.05). Pulmonary function test, arterial blood gases collected during period of clinical stability and at admission and nutritional status were similar in both groups. The mortality, at six months, was 36%. The ADL score was a significant predictor of 6-month mortality (80 with an ADL score <4, 20 with an ADL score ≥4, p < 0.01). Our pilot study demonstrates that the ADL score is predictive of weaning success and mortality at 6 months, suggesting that the assessment of daily activities should be an important component of ARF management in COPD patients.

Older adults commonly experience mild declines in everyday functioning and the strategic aspects of prospective memory (PM). This study used multiprocess theory to examine whether the strategic demands of retrieval cue type (event vs. time based) and delay interval length (2 vs. 15 min) influence the relationship between PM and activities of daily living (ADLs) in older adults. Participants included 97 community-dwelling older adults recruited from the Western Australia Participant Pool. Participants were administered the Memory for Intentions Screening Test (MIST) and Prospective and Retrospective Memory Questionnaire (PRMQ) as part of a larger neurocognitive assessment. A knowledgeable informant completed the Activities of Daily Living Questionnaire (ADLQ), from which a cutpoint of ≥ 1 was used to classify participants into "ADL normal" (n = 37) or "mild ADL problems" (n = 60) groups. Repeated measures multivariate analysis of variance (MANOVA) controlling for age was conducted with ADL group as the between-subjects factor and either MIST or PRMQ cue and delay scores as the within-subjects factors. We observed a significant ADL group by PM interaction on the MIST, with pair-wise analyses showing that the mild ADL problems group performed worse than ADL normal participants on the 15-min time-based scale (p < .001, Cohen's d = 0.71). No other MIST or PRMQ cue-delay variable differed between the two ADL groups (ps > .10). Findings indicate that decrements in strategically demanding cue monitoring and detection over longer PM delays may partly explain older adults' mild problems in everyday functioning. Findings may inform neuropsychological interventions aimed at maintaining ADL independence and enhancing quality of life in older adults.

Cognitive impairment due to dementia decreases functionality in Activities of Daily Living (ADL). Its assessment is useful to identify care needs, risks and monitor disease progression. This study investigates differences in ADL pattern-performance between dementia patients and healthy controls using unobtrusive sensors. Around 9,600 person-hours of activity data were collected from the home of ten dementia patients and ten healthy controls using a wireless-unobtrusive sensors and analysed to detect ADL. Recognised ADL were visualized using activity maps, the heterogeneity and accuracy to discriminate patients from healthy were analysed. Activity maps of dementia patients reveal unorganised behaviour patterns and heterogeneity differed significantly between the healthy and diseased. The discriminating accuracy increases with observation duration (0.95 for 20 days). Unobtrusive sensors quantify ADL-relevant behaviour, useful to uncover the effect of cognitive impairment, to quantify ADL-relevant changes in the course of dementia and to measure outcomes of anti-dementia treatments.

The causes of decreased activity of daily life (ADL) in elderly patients include cerebrovascular diseases, bone fracture by falls, and dementia. The present study was conducted among elderly patients with decreased ADL who were hospitalized in nursing wards in order to investigate the causes of becoming early bedridden and to determine precautionary measures against decreased ADL. The study subjects were 224 elderly patients with decreased ADL (mean age: 83.3 ± 8.0 years) and 49 outpatients without decreased ADL (mean age: 76.8 ± 5.3 years). Current age, age at the start of ADL decrease, medical history and history of smoking were investigated. In the groups with decreased ADL, current age and the age of becoming bedridden in non-diabetic versus diabetic groups were 84.7 ± 7.9 versus 80.3 ± 7.5 and 82.7 ± 8.3 versus 77.6 ± 8.0 years, respectively, both showing significantly lower values in the diabetic group (P < 0.05). Multiple regression analysis revealed that sex difference and diabetes were the factors determining the age of becoming early bedridden. Diabetic patients with smoking habit were significantly younger than diabetic and non-diabetic patients without smoking habit. Sex difference, smoking habit and presence of diabetes mellitus are independent risk factors of becoming early bedridden. Therefore, the major targets of medical care among elderly should be diabetic men with a smoking habit to lower the risks of decreased ADL. © 2011 Japan Geriatrics Society.

To determine whether hospital costs are higher in patients with lower functional status at admission, defined as dependence in one or more activities of daily living (ADLs), after adjustment for Medicare Diagnosis-Related Group (DRG) payments. Prospective study. General medical service at a teaching hospital. One thousand six hundred twelve patients aged 70 and older. The hospital cost of care for each patient was determined using a cost management information system, which allocates all hospital costs to individual patients. Hospital costs were higher in patients dependent in ADLs on admission than in patients independent in ADLs on admission ($5,300 vs $4,060, P<.01). Mean hospital costs remained higher in ADL-dependent patients than in ADL-independent patients in an analysis that adjusted for DRG weight ($5,240 vs $4,140, P<.01), and in multivariate analyses adjusting for age, race, sex, Charlson comorbidity score, acute physiology and chronic health evaluation score, and admission from a nursing home as well as for DRG weight ($5,200 vs $4,220, P<.01). This difference represents a 23% (95% confidence interval=15-32%) higher cost to take care of older dependent patients. Hospital cost is higher in patients with worse ADL function, even after adjusting for DRG payments. If this finding is true in other hospitals, DRG-based payments provide hospitals a financial incentive to avoid patients dependent in ADLs and disadvantage hospitals with more patients dependent in ADLs.

To determine how self-reported physical function relates to performance in each of three mobility domains: walking, stance maintenance, and rising from chairs. Cross-sectional analysis of older adults. University-based laboratory and community-based congregate housing facilities. Two hundred twenty-one older adults (mean age, 79.9 years; range, 60-102 years) without clinical evidence of dementia (mean Folstein Mini-Mental State score, 28; range, 24-30). We compared the responses of these older adults on a questionnaire battery used by the Established Populations for the Epidemiologic Study of the Elderly (EPESE) project, to performance on mobility tasks of graded difficulty. Responses to the EPESE battery included: (1) whether assistance was required to perform seven Katz activities of daily living (ADL) items, specifically with walking and transferring; (2) three Rosow-Breslau items, including the ability to walk up stairs and walk a half mile; and (3) five Nagi items, including difficulty stooping, reaching, and lifting objects. The performance measures included the ability to perform, and time taken to perform, tasks in three summary score domains: (1) walking ("Walking," seven tasks, including walking with an assistive device, turning, stair climbing, tandem walking); (2) stance maintenance ("Stance," six tasks, including unipedal, bipedal, tandem, and maximum lean); and (3) chair rise ("Chair Rise," six tasks, including rising from a variety of seat heights with and without the use of hands for assistance). A total score combines scores in each Walking, Stance, and Chair Rise domain. We also analyzed how cognitive/ behavioral factors such as depression and self-efficacy related to the residuals from the self-report and performance-based ANOVA models. Rosow-Breslau items have the strongest relationship with the three performance domains, Walking, Stance, and Chair Rise (eta-squared ranging from 0.21 to 0.44). These three performance domains are as strongly related to one Katz ADL item, walking (eta-squared ranging from 0.15 to 0.33) as all of the Katz ADL items combined (eta-squared ranging from 0.21 to 0.35). Tests of problem solving and psychomotor speed, the Trails A and Trails B tests, are significantly correlated with the residuals from the self-report and performance-based ANOVA models. Compared with the rest of the EPESE self-report items, self-report items related to walking (such as Katz walking and Rosow-Breslau items) are better predictors of functional mobility performance on tasks involving walking, stance maintenance, and rising from chairs. Compared with other self-report items, self-reported walking ability may be the best predictor of overall functional mobility.

The prevalence of dementia is expected to increase rapidly, and institutionalization is a common consequence of the disease. Dependence in activities of daily living (ADL) is a predictor for institutionalization and a determinant for the quality of life (QoL). A promising method to increase functional independence in nursing homes is a restorative care or function focused care (FFC) approach. Movement-oriented restorative care (MRC) is derived from the concept of FFC and restorative care and focuses on the integration of physical activity in the daily lives of nursing home residents with dementia using a multidisciplinary approach. The objective of this study was to assess the effectiveness of MRC in preservation of ADL independence and QoL in nursing home residents with dementia. In this quasi-experimental 12-month study, the effects of MRC were compared to care as usual in 61 nursing home residents with moderate to severe dementia. The outcome measures were ADL independence and QoL. These outcomes were measured five times (i.e. at baseline, and after 3, 6, 9, and 12 months). Additionally, data was collected regarding the degree of implementation, and the barriers to the implementation process. The effect of the intervention was analyzed using linear mixed model analyses. There was no significant overall intervention effect on ADL independence and QoL. A significant group-by-time interaction was found for the QoL subscale positive self-image: after a 12 month intervention period, the MRC group scored significantly better than the control group on positive self-image. Regarding the other subscales and the total score of the QoL, as well as ADL, no significant group-by-time interactions were found. MRC did not demonstrate significant improvements in ADL or QoL. After a 12-month intervention period, residents who received MRC showed higher scores on positive self-image compared to the control group. This study contributes to the limited research regarding the effect of MRC on resident outcomes. Further large-scale studies are recommended. The trial was retrospectively registered in http://clinicaltrials.gov on February 2, 2017: NCT03001232 .

Scaling functional status within the interRAI suite of assessment instruments

PubMed Central

2013-01-01

Background As one ages, physical, cognitive, and clinical problems accumulate and the pattern of loss follows a distinct progression. The first areas requiring outside support are the Instrumental Activities of Daily Living and over time there is a need for support in performing the Activities of Daily Living. Two new functional hierarchies are presented, an IADL hierarchical capacity scale and a combination scale integrating both IADL and ADL hierarchies. Methods A secondary analyses of data from a cross-national sample of community residing persons was conducted using 762,023 interRAI assessments. The development of the new IADL Hierarchy and a new IADL-ADL combined scale proceeded through a series of interrelated steps first examining individual IADL and ADL item scores among persons receiving home care and those living independently without services. A factor analysis demonstrated the overall continuity across the IADL-ADL continuum. Evidence of the validity of the scales was explored with associative analyses of factors such as a cross-country distributional analysis for persons in home care programs, a count of functional problems across the categories of the hierarchy, an assessment of the hours of informal and formal care received each week by persons in the different categories of the hierarchy, and finally, evaluation of the relationship between cognitive status and the hierarchical IADL-ADL assignments. Results Using items from interRAI’s suite of assessment instruments, two new functional scales were developed, the interRAI IADL Hierarchy Scale and the interRAI IADL-ADL Functional Hierarchy Scale. The IADL Hierarchy Scale consisted of 5 items, meal preparation, housework, shopping, finances and medications. The interRAI IADL-ADL Functional Hierarchy Scale was created through an amalgamation of the ADL Hierarchy (developed previously) and IADL Hierarchy Scales. These scales cover the spectrum of IADL and ADL challenges faced by persons in the community. Conclusions An integrated IADL and ADL functional assessment tool is valuable. The loss in these areas follows a general hierarchical pattern and with the interRAI IADL-ADL Functional Hierarchy Scale, this progression can be reliably and validly assessed. Used across settings within the health continuum, it allows for monitoring of individuals from relative independence through episodes of care. PMID:24261417

There has been an increase in research on the effect that virtual reality (VR) can have on physical rehabilitation following stroke. However, research exploring participant perceptions of VR for post-stroke rehabilitation has been limited. Semi-structured interviews were conducted with 10 chronic stroke participants (10 males, mean age = 72.1, mean time since injury = 38.6 mos.) who had recently completed an upper extremity VR stroke rehabilitation programme. Four main themes emerged: 'the VR experience,' 'functional outcomes,' 'instruction,' and the 'future of VR in stroke rehabilitation,' along with nine sub-themes. Participants illustrated the positive impact that VR training had on their functional abilities as well as their confidence towards completing activities of daily living (ADL). Participants also expressed the need for increased rehabilitation opportunities within the community. Overall, participants were optimistic about their experience with VR training and all reported that they had perceived functional gain. VR is an enjoyable rehabilitation tool that can increase a stroke survivor's confidence towards completing ADL. Implications for Rehabilitation Although there is an increase in rehabilitation programmes geared towards those with chronic stroke, we must also consider the participants' perception of those programmes. Incorporating participant feedback may increase enjoyment and adherence to the rehabilitation programmes. The VR experience, as well as provision of feedback and instruction, are important aspects to consider when developing a VR programme for stroke survivors. VR for rehabilitation may be a feasible tool for increasing the survivors' confidence in completing ADL post-stroke.

Background The aim of this study was to verify the effectiveness and efficacy of saving time and reducing burden for patients, nurses, and even occupational therapists through computer adaptive testing (CAT). Methods Based on an item bank of the Barthel Index (BI) and the Frenchay Activities Index (FAI) for assessing comprehensive activities of daily living (ADL) function in stroke patients, we developed a visual basic application (VBA)-Excel CAT module, and (1) investigated whether the averaged test length via CAT is shorter than that of the traditional all-item-answered non-adaptive testing (NAT) approach through simulation, (2) illustrated the CAT multimedia on a tablet PC showing data collection and response errors of ADL clinical functional measures in stroke patients, and (3) demonstrated the quality control of endorsing scale with fit statistics to detect responding errors, which will be further immediately reconfirmed by technicians once patient ends the CAT assessment. Results The results show that endorsed items could be shorter on CAT (M = 13.42) than on NAT (M = 23) at 41.64% efficiency in test length. However, averaged ability estimations reveal insignificant differences between CAT and NAT. Conclusion This study found that mobile nursing services, placed at the bedsides of patients could, through the programmed VBA-Excel CAT module, reduce the burden to patients and save time, more so than the traditional NAT paper-and-pencil testing appraisals.

The aim of this longitudinal study was to describe whether an increase in knee extension strength is associated with improvements in managing in activities of daily living (ADL) and in self-perceived physical condition in fall-prone community-dwelling older women. Subjects (n=417) aged ≥ 65 years belonged either to intervention or control groups in a 12-month randomized controlled fall prevention trial. Isometric muscle strength of knee extension was measured with an adjustable dynamometer chair. Managing in activities of daily living was measured with structured questions about abilities to climb stairs, walk at least 400 meters, toilet, bath, go to the sauna, do light or heavy housework, and carry heavy loads. A question of self-perceived physical condition was also asked. Positive associations were found between increased knee extension strength and an increase in walking at least 400 meters (p<0.001), carrying heavy loads (p=0.004), and climbing stairs (p=0.007), and in self perceived physical condition (p=0.005) over a 12- month follow-up. In addition, low age, non-use of a walking aid, low number of prescribed medications, and good functional balance at baseline were associated with an increase in performance of these ADL functions. An increase in knee extension strength during the 12-month follow-up was associated with improvement in some ADL functions and improvement in self-perceived physical condition during the same period in fall-prone community-dwelling women.

To identify all published studies using the Arm Motor Ability Test (AMAT), a standardized, laboratory-based measure for selected upper extremity activities of daily living (ADLs); and to summarize its current uses and provide recommendations for its future use. An Ovid online search was performed using the terms "Arm Motor Ability Test" and "AMAT." The reference lists of all articles obtained were reviewed for additional studies not appearing in the literature search. In addition, the original manual for the use and administration of the AMAT was reviewed. All studies examining the psychometric properties of the AMAT or using the AMAT as an outcome measure were identified. Articles simply mentioning the AMAT without providing data and case reports or abstracts (other than those addressing a specific aspect of the scale of interest) were excluded. Studies were reviewed by the primary author. No formal system of quality review was used. The AMAT has been used as an outcome measure in stroke rehabilitation research examining upper extremity robotics, functional electrical stimulation, and cortical stimulation. The most recent version contains 10 ADL tasks, each of which is composed of 1 to 3 subtasks. Of the 3 domains originally proposed, only the "functional ability" domain is routinely assessed. Psychometric studies have demonstrated good reliability and at least reasonable construct validity. The instrument's sensitivity to change over time is less well established, and no recommendation can be made regarding a minimal clinically important difference. We recommend that the 10-item version of the AMAT and assessment of only the functional ability domain be adopted as standard going forward. Further research should include examination of sensitivity over time, minimal clinically important change, reliability and validity in the mid and lower range of scores, and in neurologic diagnoses other than stroke.

In the Emergency Department (ED), early and rapid identification of older people at risk of adverse outcomes, who could best benefit from complex geriatric intervention, would avoid wasting time, especially in terms of prevention of adverse outcomes, and ensure optimal orientation of vulnerable patients. We wanted to test the predictive ability of a screening tool assessing risk of functional decline (FD), named SHERPA, 10 years after its conception, and to assess the added value of other clinical or biological factors associated with FD. A prospective cohort study of older patients (n = 305, ≥ 75 years) admitted through the emergency department, for at least 48 h in non-geriatric wards (mean age 82.5 ± 4.9, 55% women). SHERPA variables (i.e. age, pre-admission instrumental Activity of Daily Living (ADL) status, falls within a year, self-rated health and 21-point MMSE) were collected within 48 h of admission, along with socio-demographic, medical and biological data. Functional status was followed at 3 months by phone. FD was defined as a decrease at 3 months of at least one point in the pre-admission basic ADL score. Predictive ability of SHERPA was assessed using c-statistic, predictive values and likelihood ratios. Measures of discrimination improvement were Net Reclassification Improvement and Integrated Discrimination Improvement. One hundred and five patients (34%) developed 3-month FD. Predictive ability of SHERPA decreased dramatically over 10 years (c = 0.73 vs. 0.64). Only two of its constitutive variables, i.e. falls and instrumental ADL, were significant in logistic regression analysis for functional decline, while 21-point MMSE was kept in the model for clinical relevance. Demographic, comorbidity or laboratory data available upon admission did not improve the SHERPA predictive yield. Prediction of FD with SHERPA is difficult, but predictive factors, i.e. falls, pre-existing functional limitation and cognitive impairment, stay consistent across time and with literature. As accuracy of SHERPA and others existing screening tools for FD is moderate, using these predictors as flags instead of using composite scales can be a way to screen for high-risk patients.

Why do dementia patients become unable to lead a daily life with decreasing cognitive function?

In order to understand the words and deeds of dementia patients that we find very hard to explain or understand, we have paid attention to the self-awareness ability of dementia patients, the intellectual subject that integrates their own intellectual functions, and created 'a model for interpreting puzzling words and deeds of dementia patients from the viewpoint of self-awareness'. The purpose of this study is to explain the reasons why dementia patients become unable to successfully perform activities of daily living (ADL) with advancement of dementia, using our model to present viewpoints understandable to caregivers. We classified dementia inpatients of a geriatric health services facility into four stages, using the model of self-awareness ability (consisting of 'theory of mind', 'self-evaluation' and 'self-consciousness') that was constructed by combining 'theory of mind' and Lewis's developmental model of cognition and emotion. Furthermore, we observed and documented scenes from daily life, and we interpreted the reasons why patients become unable to seek assistance from others for ADL, based on the model. We came to understand why the patients could not seek assistance from others, because the patients who failed in the task of 'theory of mind' were unable to self-assess their own mind and the minds of others, and those having failed in the task of 'self-evaluation' could not evaluate their own situation.

Multiple sclerosis has a vast impact on health, but the relationship between walking, manual dexterity, cognition and activity/participation is unclear. The specific aims were to explore the discriminative ability of measures of walking, manual dexterity and cognition, and to identify cut-off values in these measures, for prediction of independence in personal and instrumental activities of daily living (ADL) and activity/participation in social and lifestyle activities. Data from 164 persons with multiple sclerosis were collected during home visits with the following measures: the 2 × 5 m walk test, the Nine-hole Peg Test, the Symbol Digit Modalities Test, the Katz Personal and Instrumental ADL Indexes, and the Frenchay Activities Index (measuring frequency in social and lifestyle activities). The 2 × 5 m walk test and the Nine-hole Peg Test had high and better discriminative and predictive ability than the Symbol Digit Modalities Test. Cut-off values were identified. The accuracy of predictions was increased above all by combining the 2 × 5 m walk test and the Nine-hole Peg Test. The proposed cut-off values in the 2 × 5 m walk test and the Nine-hole Peg Test may be used as indicators of functioning and to identify persons risking activity limitations and participation restrictions. However, further studies are needed to confirm the usefulness in clinical practice.

Attention deficits have been linked to poor recovery after stroke and may predict outcome. We explored the influence of attention on functional recovery post stroke in the first 12 months after discharge from hospital. People with stroke completed measures of attention, balance, mobility and activities of daily living (ADL) ability at the point of discharge from hospital, and 6 and 12 months later. We used correlational analysis and stepwise linear regression to explore potential predictors of outcome. We recruited 122 men and women, mean age 70 years. At discharge, 56 (51%) had deficits of divided attention, 45 (37%) of sustained attention, 43 (36%) of auditory selective attention and 41 (37%) had visual selective attention deficits. Attention at discharge correlated with mobility, balance and ADL outcomes 12 months later. After controlling for the level of the outcome at discharge, correlations remained significant in only five of the 12 relationships. Stepwise linear regression revealed that the outcome measured at discharge, days until discharge and number of medications were better predictors of outcome: in no case was an attention variable at discharge selected as a predictor of outcome at 12 months. Although attention and function correlated significantly, this correlation was reduced after controlling for functional ability at discharge. Furthermore, side of lesion and the attention variables were not demonstrated as important predictors of outcome 12 months later.

Patients with vascular dementia (VaD) are often isolated, withdrawn from society because of negative symptoms and functional disabilities. The aim of this study was to detect factors associated with social withdrawal in patients with VaD. The participants were 36 institutionalized patients with VaD. Social withdrawal was assessed with the social withdrawal of the Multidimensional Observation Scale for Elderly Subjects (MOSES). Possible explanatory variables were the MOSES items depression and self-care, Cognitive Abilities Screening Instrument (CASI), apathy evaluation scale (AES), and Behavioral Pathology in Alzheimer's Disease Frequency-Weighted Severity Scale (BEHAVE-AD-FW). Multiple regression analyses were conducted for two groups: Analysis 1 was performed in all patients (N = 36) and Analysis 2 was performed in the patients with the ability to move by themselves (i.e., independent walking or independent movement with a cane or a wheelchair; n = 28). In Analysis 1, MOSES item social withdrawal was correlated with AES and MOSES item self-care. In Analysis 2, MOSES item social withdrawal was correlated with AES and CASI domain abstraction and judgment. Decreased social activities of VaD were not related to general cognitive function or depression. Disturbed activities of daily living (ADLs) for self-care may involve decreased frontal lobe function, indicating that comprehensive rehabilitation for both ADL and dementia are needed to improve the social activities of patients with VaD.

This paper presents the results of a descriptive survey on human grasps. Sixty-four videos were selected to represent tasks performed in the main areas of activities of daily living (ADL) (personal care, meal preparation, eating, housekeeping, etc.). All the participants were right-handed. Elementary grasps were identified for each hand, and the grasp type (from a 9-type classification), the hands involved, and the duration were registered for each case. The results show that the most commonly used grasps are: pinch, non-prehensile, cylindrical, lateral pinch and lumbrical. The presence of these grasps in the areas of ADL is, however, very different (e.g., pinch is widely used in food preparation and very little in driving). Some grasps were used more frequently with one hand or when both hands were used simultaneously (e.g., special pinch was hardly used by the left hand). Knowing the grasp types most frequently used in ADL is essential to be able to assess grasp rehabilitation processes or hand prostheses development. Copyright © 2014 Hanley & Belfus.

Unconventional function of an Achaete-Scute homolog as a terminal selector of nociceptive neuron identity

2018-01-01

Proneural genes are among the most early-acting genes in nervous system development, instructing blast cells to commit to a neuronal fate. Drosophila Atonal and Achaete-Scute complex (AS-C) genes, as well as their vertebrate orthologs, are basic helix-loop-helix (bHLH) transcription factors with such proneural activity. We show here that a C. elegans AS-C homolog, hlh-4, functions in a fundamentally different manner. In the embryonic, larval, and adult nervous systems, hlh-4 is expressed exclusively in a single nociceptive neuron class, ADL, and its expression in ADL is maintained via transcriptional autoregulation throughout the life of the animal. However, in hlh-4 null mutants, the ADL neuron is generated and still appears neuronal in overall morphology and expression of panneuronal and pansensory features. Rather than acting as a proneural gene, we find that hlh-4 is required for the ADL neuron to function properly, to adopt its correct morphology, to express its unusually large repertoire of olfactory receptor–encoding genes, and to express other known features of terminal ADL identity, including neurotransmitter phenotype, neuropeptides, ion channels, and electrical synapse proteins. hlh-4 is sufficient to induce ADL identity features upon ectopic expression in other neuron types. The expression of ADL terminal identity features is directly controlled by HLH-4 via a phylogenetically conserved E-box motif, which, through bioinformatic analysis, we find to constitute a predictive feature of ADL-expressed terminal identity markers. The lineage that produces the ADL neuron was previously shown to require the conventional, transient proneural activity of another AS-C homolog, hlh-14, demonstrating sequential activities of distinct AS-C-type bHLH genes in neuronal specification. Taken together, we have defined here an unconventional function of an AS-C-type bHLH gene as a terminal selector of neuronal identity and we speculate that such function could be reflective of an ancestral function of an “ur-” bHLH gene.

The Personal Mobility and Manipulation Appliance (PerMMA) is a recently developed personal assistance robot created to provide people with severe physical disabilities enhanced assistance in both mobility and manipulation. PerMMA aims to improve functional independence when a personal care attendant is not available on site. PerMMA integrates both a smart powered wheelchair and two dexterous robotic arms to assist its users in completing essential mobility and manipulation tasks during basic and instrumental activities of daily living (ADL). Two user interfaces were developed: a local control interface and a remote operator controller. This paper reports on the evaluation of PerMMA with end users completing basic ADL tasks. Participants with both lower and upper extremity impairments (N=15) were recruited to operate PerMMA and complete up to five ADL tasks in a single session of no more than two hours (to avoid fatigue or frustration of the participants). The performance of PerMMA was evaluated by participants completing ADL tasks with two different control modes: local mode and cooperative control. The users' task completion performance and answers on pre/post-evaluation questionnaires demonstrated not only the ease in learning and usefulness of PerMMA, but also their attitudes toward assistance from advanced technology like PerMMA. As a part of the iterative development process, results of this work will serve as supporting evidence to identify design criteria and other areas for improvement of PerMMA. Copyright © 2013 IPEM.

Psychometric evaluation of a new assessment of the ability to manage technology in everyday life.

PubMed

Malinowsky, Camilla; Nygård, Louise; Kottorp, Anders

2011-03-01

Technology increasingly influences the everyday lives of most people, and the ability to manage technology can be seen as a prerequisite for participation in everyday occupations. However, knowledge of the ability and skills required for management of technology is sparse. This study aimed to validate a new observation-based assessment, the Management of Everyday Technology Assessment (META). The META has been developed to assess the ability to manage technology in everyday life. A sample of 116 older adults with and without cognitive impairment were observed and interviewed by the use of the META when managing their everyday technology at home. The results indicate that the META demonstrates acceptable person response validity and technology goodness-of-fit. Additionally, the META can separate individuals with higher ability from individuals with lower ability to manage everyday technology. The META can be seen as a complement to existing ADL assessment techniques and is planned to be used in both research and practice.

To assess the incidence of anti-drug antibodies (ADA) in patients with rheumatoid arthritis (RA) treated with the TNF inhibitors etanercept (ETN), adalimumab (ADL), or infliximab (IFX), and determine the potential relationship with trough drug concentration, efficacy, and patient-reported outcomes. This multi-national, non-interventional, cross-sectional study (NCT01981473) enrolled adult patients with RA treated continuously for 6-24 months with ETN, ADL, or IFX. ADA and trough drug concentrations were measured by independent assays ≤2 days before the next scheduled dose. Efficacy measurements included Disease Activity Score 28-joint count (DAS28), low disease activity (LDA), remission, and erythrocyte sedimentation rate (ESR). Targeted medical histories of injection site/infusion reactions, serum sickness, and thromboembolic events were collected. Baseline demographics of the 595 patients (ETN: n = 200; ADL: n = 199; IFX: n = 196) were similar across groups. The mean duration of treatment was 14.6, 13.5, and 13.1 months for ETN, ADL, and IFX, respectively. All ETN-treated patients tested negative for ADA, whereas 31.2% and 17.4% patients treated with ADL and IFX, respectively, tested positive. In ADL- or IFX-treated patients, those with ADA had significantly lower trough drug concentrations. There were negative correlations between trough drug levels and both CRP and ESR in ADL- and IFX-treated patients. DAS28-ESR LDA and remission rates were higher in patients without ADA. The rate of targeted medical events reported was low. ADA were detected in ADL- and IFX-treated but not ETN-treated patients. Patients without ADA generally showed numerically better clinical outcomes than those with ADA. This study was registered on www.ClinicalTrials.gov (NCT01981473).

The aim of this study was to evaluate the activity of daily living (ADL) and surgical interventions in patients with mucopolysaccharidosis IVA (MPS IVA). The factor(s) that affect ADL are age, clinical phenotypes, surgical interventions, therapeutic effect, and body mass index. The ADL questionnaire comprises three domains: "Movement," "Movement with cognition," and "Cognition." Each domain has four subcategories rated on a 5-point scale based on the level of assistance. The questionnaire was collected from 145 healthy controls and 82 patients with MPS IVA. The patient cohort consisted of 63 severe and 17 attenuated phenotypes (2 were undefined); 4 patients treated with hematopoietic stem cell transplantation (HSCT), 33 patients treated with enzyme replacement therapy (ERT) for more than a year, and 45 untreated patients. MPS IVA patients show a decline in ADL scores after 10years of age. Patients with a severe phenotype have a lower ADL score than healthy control subjects, and lower scores than patients with an attenuated phenotype in domains of "Movement" and "Movement with cognition." Patients, who underwent HSCT and were followed up for over 10years, had higher ADL scores and fewer surgical interventions than untreated patients. ADL scores for ERT patients (2.5years follow-up on average) were similar with the-age-matched controls below 10years of age, but declined in older patients. Surgical frequency was higher for severe phenotypic patients than attenuated ones. Surgical frequency for patients treated with ERT was not decreased compared to untreated patients. In conclusion, we have shown the utility of the proposed ADL questionnaire and frequency of surgical interventions in patients with MPS IVA to evaluate the clinical severity and therapeutic efficacy compared with age-matched controls.

Purpose Estimating drug effectiveness and safety among older adults in population-based studies using administrative healthcare claims can be hampered by unmeasured confounding due to frailty. A claims-based algorithm that identifies patients likely to be dependent, a proxy for frailty, may improve confounding control. Our objective was to develop an algorithm to predict dependency in activities of daily living (ADL) in a sample of Medicare beneficiaries. Methods Community-dwelling respondents to the 2006 Medicare Current Beneficiary Survey, >65 years old, with Medicare Part A, B, home health, and hospice claims were included. ADL dependency was defined as needing help with bathing, eating, walking, dressing, toileting, or transferring. Potential predictors were demographics, ICD-9 diagnosis/procedure and durable medical equipment codes for frailty-associated conditions. Multivariable logistic regression was to predict ADL dependency. Cox models estimated hazard ratios for death as a function of observed and predicted ADL dependency. Results Of 6391 respondents, 57% were female, 88% white, and 38% were ≥80. The prevalence of ADL dependency was 9.5%. Strong predictors of ADL dependency were charges for a home hospital bed (OR=5.44, 95% CI=3.28–9.03) and wheelchair (OR=3.91, 95% CI=2.78–5.51). The c-statistic of the final model was 0.845. Model-predicted ADL dependency of 20% or greater was associated with a hazard ratio for death of 3.19 (95% CI: 2.78, 3.68). Conclusions An algorithm for predicting ADL dependency using healthcare claims was developed to measure some aspects of frailty. Accounting for variation in frailty among older adults could lead to more valid conclusions about treatment use, safety, and effectiveness. PMID:25335470

Longevity is a complex biological process for which the phenotypes have not been established. Preservation of cognitive and physical function may be important and preservation of these functions is, in part, inherited. We investigated the relation between rate of change in cognitive and functional abilities in probands and risk of death in their siblings. Probands were classified as showing no decline, slow, medium, or rapid rate of decline, based on the slope of change in cognitive and physical/functional factors over three or more assessments. Siblings of probands who did not decline on measures of memory, visuospatial/cognitive function or ADL skills were approximately half as likely to die as siblings of probands who had the most rapid decline. The reduction in risk of death in siblings of probands who did not decline in was primarily observed among siblings of probands who were older than 75 years, suggesting that genetic influences on life span may be greater at older ages. There was no association between probands' rate of change in language, IADL skills, upper or lower extremity mobility and risk of death in siblings. The results of the present study identify phenotypes associated with preserved cognitive and functional abilities which may serve as markers for longevity.

There is a lack of occupation-focused instruments to assess Activities of Daily Living (ADL) that are intended for persons with mental disorders. The ADL Taxonomy is an instrument that is widely-used within clinical practice for persons with physical impairment. The aim of this study was to adapt the ADL Taxonomy for persons with mental disorders and evaluate its validity. An expert group of Occupational Therapists (OTs) from psychiatric care adapted the ADL Taxonomy to fit the client group, including creating three new items. OTs in psychiatric care collected client data and evaluated the instrument for usability. Rasch analysis was used to evaluate the contruct validity of 16 activities separately. The OTs collected 123 assessments from clients with various mental disorders. Ten activities had excellent, and four had acceptable, psychometric properties with regard to item and person fit and unidimensionality. The activity managing the day/time gave complex results and would benefit from further development. The OTs found the test version intelligible, relevant and easy to use. The ADL Taxonomy for persons with mental disorders has 16 activities with three to six actions each, and is now ready for clinical use.

Introduction. Hypertension and cigarette smoking are dominant risk factors for cardiovascular disease in Japan while in westernized countries, broader effects encompass obesity, diabetes, and hypercholesterolemia. This paper examines whether different associations also appear important in the manifestation of activities of daily living (ADL) in older Japanese men in Hawaii and Japan. Methods. Measures of ADL (feeding, toileting, dressing, bathing, and walking around the house) were assessed from 1995 to 1999 in 1,893 men in Hawaii and 543 men in Japan. Concomitant risk factors were measured from 1990 to 1993. Results. In Hawaii, diabetes increased the odds of ≥1 ADL impairment nearly 1.5-fold (P = .020). A similar association was absent in Japan. In contrast, the odds of an ADL impairment in Japan was increased more than 5-fold in the presence of stroke (P < .001). The association in Hawaii was significantly weaker (P = .007). In both cohorts, past alcohol use was associated with a greater likelihood of ADL impairment. Conclusion. In this comparison of genetically similar samples, findings suggest that different strengths in risk factor associations with cardiovascular disease in Japan and westernized countries may also include different strengths in associations with impaired ADL.

Localized scleroderma (LoS) involves dermal but not internal inflammation and fibrosis. Cosmetic changes often impact quality of life (QOL), however, impairment of activities of daily living (ADL) in LoS patients has not been investigated. To determine what factor(s) are associated with ADL in adult patients with LoS, we performed a retrospective observational study in 177 Japanese adult LoS patients using a novel LoS disability score based on Barthel's indices of ADL: feeding, bathing, grooming, dressing, bowels, bladder, toilet use, transfers, mobility and stairs. LoS disability scores increased in proportion to the number of affected body parts but were not correlated to age and duration of illness. The presence of leg lesions significantly impaired ADL of LoS patients compared with lesions on other body parts. Patients treated with systemic medications, who tended to have multiple lesions, presented higher LoS disability scores than those without systemic treatments. Our study proposes that physicians evaluate ADL, not only QOL, in LoS patients. Our findings using LoS disability scoring indicate that multiple affected body parts and leg lesions are risk factors for ADL impairment. © 2018 Japanese Dermatological Association.

To determine whether pain predicts future activity of daily living (ADL) disability or death in individuals aged 60 and older. Prospective cohort study. The 1998 to 2008 Health and Retirement Study (HRS), a nationally representative study of older community-living individuals. Twelve thousand six hundred thirty-one participants in the 1998 HRS aged 60 and older who did not need help in any ADL. Participants reporting that they had moderate or severe pain most of the time were defined as having significant pain. The primary outcome was time to development of ADL disability or death over 10 yrs, assessed at five successive 2-year intervals. ADL disability was defined as needing help performing any ADL: bathing, dressing, transferring, toileting, eating, or walking across a room. A discrete hazards survival model was used to examine the relationship between pain and incident disability over each 2-year interval using only participants who started the interval with no ADL disability. Several potential confounders were adjusted for at the start of each interval: demographic factors, seven chronic health conditions, and functional limitations (ADL difficulty and difficulty with five measures of mobility). At baseline, 2,283 (18%) participants had significant pain. Participants with pain were more likely (all P < .001) to be female (65% vs 54%), have ADL difficulty (e.g., transferring 12% vs 2%, toileting 11% vs 2%), have difficulty walking several blocks (60% vs 21%), and have difficulty climbing one flight of stairs (40% vs 12%). Over 10 years, participants with pain were more likely to develop ADL disability or death (58% vs 43%, unadjusted hazard ratio (HR) = 1.67, 95% confidence interval (CI) = 1.57-1.79), although after adjustment for confounders, participants with pain were not at greater risk for ADL disability or death (HR = 0.98, 95% CI = 0.91-1.07). Adjustment for functional status almost entirely explained the difference between the unadjusted and adjusted results. Although there are strong cross-sectional relationships between pain and functional limitations, individuals with pain are not at higher risk of subsequent disability or death after accounting for functional limitations. Like many geriatric syndromes, pain and disability may represent interrelated phenomena that occur simultaneously and require unified treatment paradigms. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

Although knee pain is common in older persons and can cause ambulatory limitation, its impact on self-reliance has rarely been examined in Japan, particularly in a community setting. The aim of this 3-year cohort study was to investigate the association of knee pain with dependence in activities of daily living (ADL) and mortality in community-dwelling older Japanese adults. In 2005, presence of knee pain was assessed by a home visit survey of 1391 older adults aged 65 years or older (participation proportion = 97.3%). A total of 1265 participants who were ADL-independent at baseline were followed for 3 years, and information on outcomes, namely death and dependence in ADL, was collected. Participants who always had knee pain were more likely to become dependent in ADL than those who reported no knee pain (multivariate-adjusted OR, 1.98; 95% CI, 1.03-3.83); however, always having knee pain was not associated with mortality or a composite outcome of ADL dependence and death. Further analyses of each component of ADL dependence revealed that knee pain was associated with a need for assistance at home (long-term care eligibility, bathing, dressing, and transferring), but not with institutionalization. The participants were highly representative of the target population and the rate of follow-up was almost perfect (99.4%). The results suggest that knee pain is associated with future dependence in ADL, particularly a need for assistance at home.

Aeolian desertification, one of the most serious environmental issues, has hampered socioeconomic development on the Qinghai-Tibet Plateau (QTP). However, research on aeolian desertification in this region has been limited. To develop a set of science-based preventive measures to mitigate desertification in this region, it is first necessary to clarify the status, evolution, and driving factors of aeolian desertification. In this study, based on extensive field investigations and a current classification system for aeolian desertification, we established a new system for interpreting aeolian desertified land (ADL) on the plateau using Landsat images from 1977, 1990, 2000, 2010, and 2015 and obtained the distribution of ADL through visual interpretation of the images. The results showed that ADL covered 392,914km 2 (15.1% of the study area) in 2015, including gravel ADL, sandy ADL, and aeolian monadnocks. Controlled by climate, landforms, the type of Quaternary deposit, and human activities, ADL is scattered throughout the plateau but is concentrated mostly in the western and northern parts. Aeolian desertification on the plateau expanded from 1977 to 2000 and then began to reverse. The evolution during the study period is the result of the combined effects of natural and human factors. Irrational human activities were the dominant factor responsible for the expansion of ADL prior to 2000, whereas the subsequent reversal was mainly caused by climate change combined with large ecological restoration projects.

The increase of the elderly population and the high prevalence of chronic diseases have contributed to the increasing importance of functional ability as a global public health problem. This study aimed to assess functional capacity in institutionalized elders, as well as undertake an exploratory analysis of its associated factors. This is a cross-sectional study with institutionalized Brazilian elders. Functional capacity was assessed using the Katz Index for Activities of Daily Living (ADL) and the Lawton Scale for Instrumental Activities of Daily Living (IADL). The characteristics of dependent individuals were described and logistic regression models were developed for both scales. Multiple models that included all selected variables were developed using a hierarchical approach. We considered the results from the Wald test (p <0.05) as a rule for progressing to the next level. A population of 760 elders was considered. The prevalence of dependence was 50.3% for ADL and 81.2% for IADL. We observed associations between ADL dependence and the following factors: self-report of stroke, difficulty of walking 400 meters, lower total scores in questions related to the temporal orientation section of the cognition test, and self-reports of frequently feeling upset. IADL dependence was associated with educational level, self-report of cancer, difficulty of walking 400 meters, use of glasses, and self-reported memory problems. Sociodemographic and health conditions were associated with functional incapacity in institutionalized elders. Based on these findings, we emphasize the importance of both prevention and treatment of chronic conditions as well as social support in the maintenance of individuals' autonomy.

The aim of this study is to establish the effect of task-oriented video gaming on using a myoelectric prosthesis in a basic activity of daily life (ADL). Forty-one able-bodied right-handed participants were randomly assigned to one of four groups. In three of these groups the participants trained to control a video game using the myosignals of the flexors and extensors of the wrist: in the Adaptive Catching group participants needed to catch falling objects by opening and closing a grabber and received ADL-relevant feedback during performance. The Free Catching group used the same game, but without augmented feedback. The Interceptive Catching group trained a game where the goal was to intercept a falling object by moving a grabber to the left and right. They received no additional feedback. The control group played a regular Mario computer game. All groups trained 20 minutes a day for four consecutive days. Two tests were conducted before and after training: one level of the training game was performed, and participants grasped objects with a prosthesis simulator. Results showed all groups improved their game performance over controls. In the prosthesis-simulator task, after training the Adaptive Catching group outperformed the other groups in their ability to adjust the hand aperture to the size of the objects and the degree of compression of compressible objects. This study is the first to demonstrate transfer effects from a serious game to a myoelectric prosthesis task. The specificity of the learning effects suggests that research into serious gaming will benefit from placing ADL-specific constraints on game development.

The aim of this study was to investigate the relationship between nutritional and functional status in acute geriatric patients including mobility and considering health status. Cross-sectional study. Hospital. 205 geriatric patients (median age 82.0 (IQR: 80-86) years, 69.3% women). Nutritional status was determined by Mini Nutritional Assessment (MNA) and patients were categorized as well-nourished (≥ 24 points), at risk of malnutrition (17-23.5 points) or as malnourished (< 17 points). Functional status was determined by Barthel Index (BI) and Timed 'Up and Go' Test (TUG) and related to MNA categories. Using binary multiple logistic regression the impact of nutritional status on functional status was examined, adjusted for health status. 60.3% of the patients were at risk of malnutrition and 29.8% were malnourished. Ability to perform basic activities of daily living (ADL) decreased with declining nutritional status. The proportion of patients unable to perform the TUG increased with worsening of nutritional status (45.0% vs. 50.4% vs. 77.0%, p<0.01). After adjusting for age, gender, number of diagnoses, disease severity and cognitive function, a higher MNA score significantly lowered the risk of being dependent in ADL (OR 0.85, 95 % CI 0.77-0.94) and inability to perform the TUG (OR 0.90, 95 % CI 0.82-0.99). Nutritional status according to MNA was related to ADL as well as to mobility in acute geriatric patients. This association remained after adjusting for health status.

Ganczak, Maria; Chrobrowski, Krzysztof

2018-01-01

Objectives: The consequences of hip fractures (HFs) in elderly persons include a deterioration in functional capacity to perform activities that enable independent living. Since prior research into this issue in Central Europe is rather scant, this study sought to assess the change in activities and instrumental activities of daily living (ADL/IADL) after HF surgery among Polish patients, to study predictors of regaining pre-fracture functional status three and six months later, and to evaluate the correlation between ADL and IADL limitations over time. Methods: A prospective study was conducted between 2011 and 2013 in a tertiary hospital in Western Poland. ADL/IADL were evaluated using the Katz index and Lawton scale, respectively. Results: About half (50.8%) of 120 patients (mean age 80.1 ± SD 7.59) had cognitive impairment (CI). Patients with CI were older (p = 0.002) and had lower scores for pre-fracture ADL/IADL (p = 0.001 and p < 0.001, respectively). Six months after HF, 33.3% of patients failed to return to their pre-fracture ADL and 62.5% failed to return to pre-fracture IADL; 20% of those who could walk before HF were unable to walk after six months. The pre-fracture Spearman correlation coefficient between ADL and IADL summary scores was 0.46; it increased to 0.70 at three months after HF surgery and 0.77 at six months (p < 0.0001). Regaining ADL after six months was more likely in patients with pre-fracture intact intellectual function and independence in pre-fracture ADL; regaining IADL, in younger patients and those with higher pre-fracture IADL scores. Conclusions: Impairment in functional performance is common after HF surgery. ADL and IADL were strongly correlated in these patients, with this increasing over time. Functional outcomes after HF were more dependent on patient characteristics than treatment-related factors. Therefore, more emphasis should be directed towards the pre-fracture period and, in particular, maintaining cognitive function and preserving functional capacity in older persons at high risk of HF.

It is important to assess activities of daily living (ADL) in older adults due to impairment of independence and quality of life. However, there is no objective and standardized protocol available to assess this outcome. Thus, the aim of this study was to verify the reproducibility and validity of a new protocol for ADL assessment applied in physically independent adults age ≥50 y, the Londrina ADL protocol, and to establish an equation to predict reference values of the Londrina ADL protocol. Ninety-three physically independent adults age ≥50 y had their performance in ADL evaluated by registering the time spent to conclude the protocol. The protocol was performed twice. The 6-min walk test, which assesses functional exercise capacity, was used as a validation criterion. A multiple linear regression model was applied, including anthropometric and demographic variables that correlated with the protocol, to establish an equation to predict the protocol's reference values. In general, the protocol was reproducible (intraclass correlation coefficient 0.91). The average difference between the first and second protocol was 5.3%. The new protocol was valid to assess ADL performance in the studied subjects, presenting a moderate correlation with the 6-min walk test (r = -0.53). The time spent to perform the protocol correlated significantly with age (r = 0.45) but neither with weight (r = -0.17) nor with height (r = -0.17). A model of stepwise multiple regression including sex and age showed that age was the only determinant factor to the Londrina ADL protocol, explaining 21% ( P < .001) of its variability. The derived reference equation was: Londrina ADL protocol pred (s) = 135.618 + (3.102 × age [y]). The Londrina ADL protocol was reproducible and valid in physically independent adults age ≥50 y. A reference equation for the protocol was established including only age as an independent variable (r 2 = 0.21), allowing a better interpretation of the protocol's results in clinical practice.

Quantifying kinematics of purposeful movements to real, imagined, or absent functional objects: implications for modelling trajectories for robot-assisted ADL tasks.

PubMed

Wisneski, Kimberly J; Johnson, Michelle J

Robotic therapy is at the forefront of stroke rehabilitation. The Activities of Daily Living Exercise Robot (ADLER) was developed to improve carryover of gains after training by combining the benefits of Activities of Daily Living (ADL) training (motivation and functional task practice with real objects), with the benefits of robot mediated therapy (repeatability and reliability). In combining these two therapy techniques, we seek to develop a new model for trajectory generation that will support functional movements to real objects during robot training. We studied natural movements to real objects and report on how initial reaching movements are affected by real objects and how these movements deviate from the straight line paths predicted by the minimum jerk model, typically used to generate trajectories in robot training environments. We highlight key issues that to be considered in modelling natural trajectories. Movement data was collected as eight normal subjects completed ADLs such as drinking and eating. Three conditions were considered: object absent, imagined, and present. This data was compared to predicted trajectories generated from implementing the minimum jerk model. The deviations in both the plane of the table (XY) and the sagittal plane of torso (XZ) were examined for both reaches to a cup and to a spoon. Velocity profiles and curvature were also quantified for all trajectories. We hypothesized that movements performed with functional task constraints and objects would deviate from the minimum jerk trajectory model more than those performed under imaginary or object absent conditions. Trajectory deviations from the predicted minimum jerk model for these reaches were shown to depend on three variables: object presence, object orientation, and plane of movement. When subjects completed the cup reach their movements were more curved than for the spoon reach. The object present condition for the cup reach showed more curvature than in the object imagined and absent conditions. Curvature in the XZ plane of movement was greater than curvature in the XY plane for all movements. The implemented minimum jerk trajectory model was not adequate for generating functional trajectories for these ADLs. The deviations caused by object affordance and functional task constraints must be accounted for in order to allow subjects to perform functional task training in robotic therapy environments. The major differences that we have highlighted include trajectory dependence on: object presence, object orientation, and the plane of movement. With the ability to practice ADLs on the ADLER environment we hope to provide patients with a therapy paradigm that will produce optimal results and recovery.

Objective Information on dependency level of elderly in rapidly aging developing countries is limited, but is needed to ascertain extent of need for help with activities of daily living (ADLs). Methods In-person information was obtained in 1995 from a statewide survey of representative community residents ≥60 years of age in the state of Rio Grande do Sul, Brazil (N=7040), on demographic characteristics, health conditions, social ties, health behaviors, and ADL performance. Results Nearly 40% needed help with one or more ADLs. In controlled analyses, need for help approximately doubled with each succeeding decade. Increased education and income and regular physical activity reduced risk. Selected health conditions (stroke, depression, poor self-rated health) were consistently associated with need for help, Discussion A large proportion of noninstitutionalized elderly have ADL problems. In addition to health care, interventions promoting equity of access to education and economic opportunity could reduce ADL dependency in coming generations. PMID:20147651

Trends in ADL and IADL Disability in Community-Dwelling Older Adults in Shanghai, China, 1998–2008

Objectives. We investigated trends in activities of daily living (ADL) and instrumental activities of daily living (IADL) disability from 1998 to 2008 among elder adults in Shanghai, China. Method. Our data came from 4 waves of the Shanghai Longitudinal Survey of Elderly Life and Opinion (1998, 2003, 2005, and 2008). ADL and IADL disabilities were recorded dichotomously (difficulty vs. no difficulty). The major independent variable was survey year. Covariates included demographics, socioeconomic conditions, family and social support, and other health conditions. Nested random-effect models were applied to estimate trends over time, referenced to 1998. Results. In comparison with the baseline year (1998), older adults in 2008 had lower odds of being ADL disabled, though the effect was no longer statistically significant when other health conditions were taken into account. Elders in 2003, 2005, and 2008 were 20%–26%, 17%–38%, and 53%–64% less likely to be IADL disabled than those in 1998, respectively, depending on the set of covariates included in the model. Discussion. Shanghai elders experienced substantial improvements in both ADL and IADL disability prevalence over the past decade. The trend toward improvement in IADL function is more consistent and substantial than that of ADL function. PMID:23525547

Background Although knee pain is common in older persons and can cause ambulatory limitation, its impact on self-reliance has rarely been examined in Japan, particularly in a community setting. The aim of this 3-year cohort study was to investigate the association of knee pain with dependence in activities of daily living (ADL) and mortality in community-dwelling older Japanese adults. Methods In 2005, presence of knee pain was assessed by a home visit survey of 1391 older adults aged 65 years or older (participation proportion = 97.3%). A total of 1265 participants who were ADL-independent at baseline were followed for 3 years, and information on outcomes, namely death and dependence in ADL, was collected. Results Participants who always had knee pain were more likely to become dependent in ADL than those who reported no knee pain (multivariate-adjusted OR, 1.98; 95% CI, 1.03–3.83); however, always having knee pain was not associated with mortality or a composite outcome of ADL dependence and death. Further analyses of each component of ADL dependence revealed that knee pain was associated with a need for assistance at home (long-term care eligibility, bathing, dressing, and transferring), but not with institutionalization. Conclusions The participants were highly representative of the target population and the rate of follow-up was almost perfect (99.4%). The results suggest that knee pain is associated with future dependence in ADL, particularly a need for assistance at home. PMID:21422701

Previous studies have reported impairments in activities of daily living (ADL) performance in the presence of irrelevant but physically/functionally related objects in dementia patients. The aim of the present study was to increase our knowledge about the impact of the presence of contextually related non-target objects on ADL execution in patients with multi-domain mild cognitive impairment (MCI) and dementia. We compared ADL execution in patients with MCI, dementia, and healthy elderly participants under two experimental conditions: One in which the target objects were embedded with contextually related non-target items that constituted the object set necessary to complete two additional (but unrequired) ADL tasks related to the target task, and a second, control condition where target objects were surrounded by isolated objects (they never constituted a whole set needed to complete an alternative ADL task). Separate analysis of ADL errors associated with the target task versus errors involving the non-target objects revealed that, although the presence of contextually related objects facilitated the accomplishment of the target task, such a condition also led to errors involving the use of irrelevant objects in dementia and MCI. The presence of contextually related non-target items produces both positive and negative effects on ADL performance. These types of non-target objects might help to cue the retrieval of the action schema related to the target task, particularly in patients with MCI. In contrast, the presence of these objects might also lead to distraction in dementia and MCI. (JINS, 2017, 23, 481-492).

To develop and assess a clinical prediction rule (CPR) to predict declines in activities of daily living (ADL) at 6 months after surgery for hip fracture repair. Prospective, cohort study. From hospital to home. Patients (N=104) with hip fractures after surgery. Not applicable. ADL were assessed using the Barthel Index at 6 months after surgery. At 6 months after surgery, 86 patients (82.6%) were known to be alive, 1 patient (1.0%) had died, and 17 (16.3%) were lost to follow-up. Thirty-two patients (37.2%) did not recover their ADL at 6 months after surgery to levels before fracture. The classification and regression trees methodology was used to develop 2 models to predict a decline in ADL: (1) model 1 included age, type of fracture, and care level before fracture (sensitivity=75.0%, specificity=81.5%, positive predictive value=70.6%, positive likelihood ratio=4.050); and (2) model 2 included the degree of independence 2 weeks postsurgery for ADL chair transfer, ADL ambulation, and age (sensitivity=65.6%, specificity=87.0%, positive predictive value=75.0%, positive likelihood ratio=5.063). The areas under the receiver operating characteristic curves of both CPR models were .825 (95% confidential interval, .728-.923) and .790 (95% confidence interval, .683-.897), respectively. CPRs with moderate accuracy were developed to predict declines in ADL at 6 months after surgery for hip fracture repair. Copyright © 2016 American Congress of Rehabilitation Medicine.

Objectives: Knowledge of the thresholds and determinants for successful femoroacetabular impingement (FAI) treatment is evolving. The primary purpose of this study was to define pre-operative outcome score thresholds that can be used to predict patients most likely to achieve meaningful clinically important difference (MCID) after arthroscopic FAI treatment. Secondarily determinants of achieving MCID were evaluated. Methods: A prospective institutional hip arthroscopy registry was reviewed to identify patients with FAI treated with arthroscopic labral surgery, acetabular rim trimming, and femoral osteochondroplasty. The modified Harris Hip Score (mHHS), the Hip Outcome Score (HOS) and the international Hip Outcome Tool (iHOT-33) tools were administered at baseline and at one year post-operatively. MCID was calculated using a distribution-based method. A receiver operating characteristic (ROC) analysis was used to calculate cohort-based threshold values predictive of achieving MCID. Area under the curve (AUC) was used to define predictive ability (strength of association) with AUC >0.7 considered acceptably predictive. Univariate and multivariable analyses were used to analyze demographic, radiographic and intra-operative factors associated with achieving MCID. Results: There were 374 patients (mean + SD age, 32.9 + 10.5) and 56.4% were female. The MCID for mHHS, HOS activities of daily living (HOS-ADL), HOS Sports, and iHOT-33 was 8.2, 8.4,14.5, and 12.0 respectively. ROC analysis (threshold, % achieving MCID, strength of association) for these tools in our population was: mHHS (61.6, 78%, 0.68), HOS-ADL (83.8, 68%, 0.84), HOS-Sports (63.9, 64%, 0.74), and iHOT-33 (54.3, 82%, 0.65). Likelihood for achieving MCID declined above and increased below these thresholds. In univariate analysis female sex, femoral version, lower acetabular outerbridge score and increasing CT sagittal center edge angle (CEA) were predictive of achieving MCID. In multivariable analysis sagittal CEA was the only variable maintaining significance (p = 0.032). Conclusion: We used a large prospective hip arthroscopy database to identify pre-operative patient outcome score thresholds predictive of meaningful post-operative outcome improvement after arthroscopic FAI treatment. This is the largest reported hip arthroscopy cohort to define MCID and the first to do so for iHOT-33. The HOS-ADL may have the best predictive ability for achieving MCID after hip arthroscopy. Patients with relatively high pre-operative ADL, quality of life and functional status appear to have a high chance for achieveing MCID up to our defined thresholds. Hip dysplasia is an important outcome modifier. The findings of this study may be useful for managing preoperative expectation for patients undergoing arthroscopic FAI surgery.

Residents in nursing homes (NHs) are often frail older persons who have impaired physical activity. Urinary incontinence (UI) is a common complaint for residents in NHs. Reduced functional ability and residence in NHs are documented to be risk factors for UI. To investigate if an individualized training program designed to improve activity of daily living (ADL) and physical capacity among residents in nursing homes has any impact on UI. This randomized controlled trial was a substudy of a Nordic multicenter study. Participants had to be >65 years, have stayed in the NH for more than 3 months and in need of assistance in at least one ADL. A total of 98 residents were randomly allocated to either a training group (n = 48) or a control group (n = 50) after baseline registrations. The training program lasted for 3 months and included accommodated physical activity and ADL training. Personal treatment goals were elicited for each subject. The control group received their usual care. The main outcome measure was UI as measured by a 24-hour pad-weighing test. There was no statistically significant difference between the groups on this measure at baseline (P = 0.15). Changes were calculated from baseline to 3 months after the end of the intervention. Altogether, 68 participants were included in the analysis, 35 in the intervention group and 33 in the control group. The average age was 84.3 years. The 3 months' postintervention adjusted mean difference between groups according to amount of leakage was 191 g (P = 0.03). This result was statistically significant after adjusting for baseline level, age, sex, and functional status. The leakage increased in residents not receiving the experimental intervention, while UI in the training group showed improvement. The intervention group had significant better results compared with the control group after an individualized training program designed to improve ADL and physical capacity. Further studies are needed to evaluate the effect of a goal-oriented physical training program toward NH residents UI complaints.

Objective To assess the incidence of anti-drug antibodies (ADA) in patients with rheumatoid arthritis (RA) treated with the TNF inhibitors etanercept (ETN), adalimumab (ADL), or infliximab (IFX), and determine the potential relationship with trough drug concentration, efficacy, and patient-reported outcomes. Methods This multi-national, non-interventional, cross-sectional study (NCT01981473) enrolled adult patients with RA treated continuously for 6–24 months with ETN, ADL, or IFX. ADA and trough drug concentrations were measured by independent assays ≤2 days before the next scheduled dose. Efficacy measurements included Disease Activity Score 28-joint count (DAS28), low disease activity (LDA), remission, and erythrocyte sedimentation rate (ESR). Targeted medical histories of injection site/infusion reactions, serum sickness, and thromboembolic events were collected. Results Baseline demographics of the 595 patients (ETN: n = 200; ADL: n = 199; IFX: n = 196) were similar across groups. The mean duration of treatment was 14.6, 13.5, and 13.1 months for ETN, ADL, and IFX, respectively. All ETN-treated patients tested negative for ADA, whereas 31.2% and 17.4% patients treated with ADL and IFX, respectively, tested positive. In ADL- or IFX-treated patients, those with ADA had significantly lower trough drug concentrations. There were negative correlations between trough drug levels and both CRP and ESR in ADL- and IFX-treated patients. DAS28-ESR LDA and remission rates were higher in patients without ADA. The rate of targeted medical events reported was low. Conclusion ADA were detected in ADL- and IFX-treated but not ETN-treated patients. Patients without ADA generally showed numerically better clinical outcomes than those with ADA. Trial registration This study was registered on www.ClinicalTrials.gov (NCT01981473). PMID:28448562

The associations of optimal levels of all major cardiovascular disease risk factors, that is, low risk, in younger age with subsequent cardiovascular disease morbidity and mortality have been well documented. However, little is known about associations of low-risk profiles in younger age with functional disability in older age. The sample included 6014 participants from the Chicago Heart Association Detection Project in Industry Study. Low-risk status, defined as untreated systolic/diastolic blood pressure ≤120/≤80 mm Hg, untreated serum total cholesterol <5.18 mmol/l, not smoking, body mass index < 25 kg/m(2), and no diabetes mellitus, was assessed at baseline (1967 to 1973). Functional disability, categorized as (1) any disability in activities of daily living (ADLs), (2) any disability in instrumental ADLs but not in ADL, or (3) no disability, was assessed from the 2003 health survey. There were 39% women, 4% Black, with a mean age of 43 years and 6% low-risk status at baseline. After 32 years, 7% reported having limitations in performing any ADL and 11% in any instrumental ADL only. The prevalence of any ADL limitation was lowest in low-risk people and increased in a graded fashion with less-favorable risk factor groups (P trend <0.001). Compared with those with 2+ high-risk factors, the multivariable-adjusted odds of having any disability in ADLs versus no disability in people with low risk, any moderate risk, and 1 high-risk factor at baseline were lower by 58%, 48%, and 37%, respectively. Results were similar for instrumental ADLs, in both men and women. Having an optimal cardiovascular disease risk factor profile at younger age is associated with the lowest rate of functional disability in older age. © 2016 American Heart Association, Inc.

Changes in self-reported function in older adults are known to occur in the 2 weeks prior to, during, and in the first few months after hospitalization. The long-term outcome of hospitalization on functional status in disabled older adults is not known. The objective of this study was to determine whether hospitalization predicts long-term Activities of Daily Living (ADL) dependence in previously ADL independent, although disabled, older women. The Women's Health and Aging Study I is a population-based, prospective cohort study of disabled, community-dwelling women > or =65 years old. We evaluated participants who were independent in ADLs at baseline and excluded women with incident stroke, lower extremity joint surgery, amputation, or hip fracture. We examined the association between self-reported incident hospitalization at three consecutive 6-month intervals and incident dependence in at least one ADL at 18 months (n = 595). Of 595 women evaluated, 32% had at least one hospitalization. Women who were hospitalized were more likely to become dependent in ADLs than were women who were not hospitalized (17% vs 8%, p =.001). In a multivariate model, hospitalization was independently predictive of development of ADL dependence that persisted at 18 months after baseline (odds ratio [OR], 3.2; 95% confidence interval [CI], 1.7-5.8), adjusting for age, race, education, baseline walking speed, difficulty with ADLs, self-reported health status, depressive symptoms, cognitive status, and presence of congestive heart failure, diabetes, or pulmonary disease. Increasing numbers of 6-month intervals with hospitalizations were independently predictive of higher risk in an adjusted model: one (OR, 2.3; 95% CI, 1.1-4.6), two (OR, 5.8; 95% CI, 2.4-14.4), and three (OR, 12.5; 95% CI, 2.7-57.6). These results suggest that hospitalization has an independent and dose-response effect on loss of ADL independence in disabled older women over an 18-month period.

Technical note: improved methodology for analyses of acid detergent fiber and acid detergent lignin.

The objective of this study was to evaluate the methodology of the acid detergent lignin (ADL) assay in an effort to evaluate particle loss, improve repeatability, and decrease variation within and among samples. The original ADL method relied on asbestos as a filtering aid, but that was removed in 1989 with the mandate from the Environmental Protection Agency to eliminate asbestos in the environment. Furthermore, recent work on fiber methodology indicated that pore size in the Gooch sintered glass crucible (40-60 μm) was too large to trap all of the small particles associated with neutral detergent fiber (NDF) and acid detergent fiber (ADF). Thus, any loss of ADF could potentially result in a loss of ADL. Sixty forages including conventional and brown midrib corn silages, alfalfa silages and hays, mature grasses, early vegetative grasses, and 9 feces samples, were analyzed sequentially for ADF and ADL as outlined in the 1973 procedure of Van Soest except for the use of the asbestos fiber. A glass microfiber filter with a 1.5-μm pore size was chosen as a filtering aid because it met the criteria required by the assay: glass, heat resistant, acid resistant, chemically inert, and hydrophobic. To compare with the current ADF and ADL assays, the assays were conducted with either no filter or the glass filter inserted into crucibles, rinsed with acetone, and then according to the 1973 procedure of Van Soest. The samples analyzed covered a range from 18.11 to 55.79% ADF and from 0.96 to 9.94% ADL on a dry matter (DM) basis. With the use of the filter, the mean ADF values increased 4.2% and mean ADL values increased 18.9%. Overall, both ADF and ADL values were greater with the use of the glass microfiber filter than without, indicating that as the type of sample analyzed changed, use of the Gooch crucible without the filtering aid results in particle loss. The adoption of the use of a small pore size (1.5 μm) glass microfiber filter to improve filtration and recovery of ADF and ADL and to reduce variation in the ADL assay is recommended, especially when sintered glass bottom crucibles are used. These differences in recovery and repeatability have implications for other fiber and lignin methods, as well as for estimating the potential changes in digestibility of fibrous feeds and feed quality.

Background The role of nutritional status in the disablement process is still unclear. The objective of this study was to assess whether low concentrations of nutrients predict the development and course of disability. Methods Longitudinal study including community-dwelling women 65 years or older enrolled in the Women’s Health and Aging Study I. In total, 643 women were assessed prospectively at 6-month intervals from 1992 to 1995. Results Incidence rates of disability in activities of daily living (ADLs) during 3 years of follow-up. Incidence rates in the lowest quartile of each selected nutrient were compared with those in the upper quartiles. The hazard ratios were estimated from Cox models adjusted for potential confounders. Women in the lowest quartile of serum concentrations of vitamin B6 (hazard ratio [HR], 1.31; 95% confidence interval [CI], 1.03–1.67), vitamin B12 (HR, 1.40; 95% CI, 1.12–1.74), and selenium (HR, 1.38; 95% CI, 1.12–1.71) had significantly higher risk of disability in ADLs during 3 years of follow-up compared with women in the upper 3 quartiles. Conclusions Low serum concentrations of vitamins B6 and B12 and selenium predict subsequent disability in ADLs in older women living in the community. Nutritional status is one of the key factors to be considered in the development of strategies aimed at preventing or delaying the disablement process. PMID:17130386

Korea introduced universal long-term care insurance (LTCI) for physically dependent older adults in 2008. Older adults, their family members, and policy makers in Korea want to know patient outcomes in different care modalities because older adults who have a similar functional status and LTC needs can choose either nursing home care or home care. The aim of this study was to compare activities of daily living (ADLs) in nursing home care and home care settings for physically dependent older adults in Korea. A retrospective 1-year cohort study using national LTCI data. This study used the LTCI dataset from the National Health Insurance Service in Korea. Participants were identified from among those in the LTCI dataset who enrolled from July 2008 to June 2010. We extracted a sample consisting of 22,557 older adults who consistently received either nursing home care (n = 11,678) or home care (n = 10,879) for 1 year. The outcome variable was change in ADLs after 1 year. Covariates were an older adult's home geographical region, LTC level, age, sex, primary caregiver, Medicaid beneficiary status, bedridden status, medical diagnosis, baseline ADLs, cognitive function, behavioral problems, nursing and special treatment, and rehabilitation needs. Multiple regression analysis of all participants unmatched and a paired t-test with a propensity-score-matched cohort were performed to explain the association of changes in ADLs with the types of LTC. Multiple regression analysis with all participants (n = 22,557) unmatched showed that compared with older adults who received home care, those who received nursing home care had deteriorated further in terms of ADLs after 1 year (β = 0.44108, P < .0001). After propensity-score matching, paired t-test analysis also found that the ADLs of older adults had deteriorated less in the home care group compared with the nursing home group after 1 year (P < .0001). The ADLs of older adults who received home care showed significantly less deterioration than those of the older adults in nursing home care after 1 year. The ADLs of older adults could differ according to the type of LTC they receive, and home care could result in better maintenance of ADLs than nursing home care.

Anosognosia, neglect, extinction and lesion site predict impairment of daily living after right-hemispheric stroke.

PubMed

Vossel, Simone; Weiss, Peter H; Eschenbeck, Philipp; Fink, Gereon R

2013-01-01

Right-hemispheric stroke can give rise to manifold neuropsychological deficits, in particular, impairments of spatial perception which are often accompanied by reduced self-awareness of these deficits (anosognosia). To date, the specific contribution of these deficits to a patient's difficulties in daily life activities remains to be elucidated. In 55 patients with right-hemispheric stroke we investigated the predictive value of different neglect-related symptoms, visual extinction and anosognosia for the performance of standardized activities of daily living (ADL). The additional impact of lesion location was examined using voxel-based lesion-symptom mapping. Step-wise linear regression revealed that anosognosia for visuospatial deficits was the most important predictor for performance in standardized ADL. In addition, motor-intentional and perceptual-attentional neglect, extinction and cancellation task performance significantly predicted ADL performance. Lesions comprising the right frontal and cingulate cortex and adjacent white matter explained additional variance in the performance of standardized ADL, in that damage to these areas was related to lower performance than predicted by the regression model only. Our data show a decisive role of anosognosia for visuospatial deficits for impaired ADL and therefore outcome/disability after stroke. The findings further demonstrate that the severity of neglect and extinction also predicts ADL performance. Our results thus strongly suggest that right-hemispheric stroke patients should not only be routinely assessed for neglect and extinction but also for anosognosia to initiate appropriate rehabilitative treatment. The observation that right frontal lesions explain additional variance in ADL most likely reflects that dysfunction of the supervisory system also significantly impacts upon rehabilitation.

In patients with chronic obstructive pulmonary disease (COPD), exercise capacity is reduced, resulting over time in physical inactivity and worsened health status. It is unknown whether ventilatory constraints occur during activities of daily life (ADL) in early stages of COPD. The aim of this study was to assess respiratory mechanics during ADL and to study its consequences on dyspnoea, physical activity and health status in early-stage COPD compared with healthy controls. In this cross-sectional study, 39 early-stage COPD patients (mean FEV 1 88±s.d. 12% predicted) and 20 controls performed 3 ADL: climbing stairs, vacuum cleaning and displacing groceries in a cupboard. Respiratory mechanics were measured during ADL. Physical activity was measured with accelerometry. Health status was assessed by the Nijmegen Clinical Screening Instrument. Compared with controls, COPD patients had greater ventilatory inefficiency and higher ventilatory requirements during ADL (P<0.05). Dyspnoea scores were increased in COPD compared with controls (P<0.001). During ADL, >50% of the patients developed dynamic hyperinflation in contrast to 10-35% of the controls. Higher dyspnoea was scored by patients with dynamic hyperinflation. Physical activity was low but comparable between both groups. From the patients, 55-84% experienced mild-to-severe problems in health status compared with 5-25% of the controls. Significant ventilatory constraints already occur in early-stage COPD patients during common ADL and result in increased dyspnoea. Physical activity level is not yet reduced, but many patients already experience limitations in health status. These findings reinforce the importance of early diagnosis of COPD and assessment of more than just spirometry.

The aim of this study was to investigate the prevalence, characteristics, and acute care utilization of community dwelling disabled older adults with an absence of help for activities of daily living (ADL). We analyzed cross-sectional data from a nationally representative sample of people aged 65 years and over (n=2904) participating in the 2009 National Health Interview Survey in Taiwan. Disability was defined as self-reporting a lot of difficulty or complete inability to carry out one or more ADL tasks. Participants with disability were asked whether they received help in the form of personal assistance or assistive devices to complete ADL tasks, with a yes response indicating the presence of help and a no response indicating the absence of help. Hospitalization and emergency department visits was assessed as a dichotomous variable (any or none), respectively. An absence of available help for ADL disability was reported in 16.6% of disabled older adults. Disabled older adults reporting an absence of help were more likely to be female. After adjustment for other factors, compared to older adults without disability, older adults with disability not receiving help for ADL tasks were highly related to hospitalization (OR=4.57; 95%CI=[1.51-13.82]) and emergency department visits (OR=3.52; 95%CI=[1.15-10.76]) during the past year, respectively. We found that there is high prevalence of absence of help to perform ADL tasks in older adults with disability, and that this absence of help for ADL disability is associated with a greater burden of acute care utilization than those without disability.

Background This study’s aim was to clarify the relationship of having hobbies and a purpose in life (PIL; in Japanese, ikigai) with mortality and a decline in the activities of daily living (ADL) and instrumental ADL (IADL) among the community-dwelling elderly. Methods Prospective observational data from residents aged ≥65 years who were at increased risk for death (n = 1853) and developing a decline in ADL (n = 1254) and IADL (n = 1162) were analyzed. Cox proportional hazard models were used for mortality analysis of data from February 2011 to November 2014. ADL and IADL were evaluated using the Barthel Index and the Tokyo Metropolitan Institute of Gerontology Index of Competence, respectively. ADL and IADL were assessed at baseline and follow-up and were evaluated using logistic regression models. Fully adjusted models included terms for age, gender, BMI, income, alcohol intake, smoking history, number of chronic diseases, cognitive function, and depression. Results During the follow-up of eligible participants, 248 had died, 119 saw a decline in ADL, and 178 saw a decline in IADL. In fully adjusted models, having neither hobbies nor PIL was significantly associated with an increased risk of mortality (hazard ratio 2.08; 95% confidence interval [CI], 1.47–2.94), decline in ADL (odds ratio 2.74; 95% CI, 1.44–5.21), and decline in IADL (odds ratio 1.89; 95% CI, 1.01–3.55) compared to having both hobbies and PIL. Conclusions Although effect modifications by cognitive functioning and depression cannot be ruled out, our findings suggest that having hobbies and PIL may extend not only longevity, but also healthy life expectancy among community-dwelling older adults.

Objective To validate the FRAIL scale. Design Longitudinal study. Setting Community. Participants Representative sample of African Americans age 49 to 65 years at onset of study. Measurements The 5-item FRAIL scale (Fatigue, Resistance, Ambulation, Illnesses, & Loss of Weight), at baseline and activities of daily living (ADLs), instrumental activities of daily living (IADLs), mortality, short physical performance battery (SPPB), gait speed, one-leg stand, grip strength and injurious falls at baseline and 9 years. Blood tests for CRP, SIL6R, STNFR1, STNFR2 and 25 (OH) vitamin D at baseline. Results Cross-sectionally the FRAIL scale correlated significantly with IADL difficulties, SPPB, grip strength and one-leg stand among participants with no baseline ADL difficulties (N=703) and those outcomes plus gait speed in those with no baseline ADL dependencies (N=883). TNFR1 was increased in pre-frail and frail subjects and CRP in some subgroups. Longitudinally (N=423 with no baseline ADL difficulties or N=528 with no baseline ADL dependencies), and adjusted for the baseline value for each outcome, being pre-frail at baseline significantly predicted future ADL difficulties, worse one-leg stand scores, and mortality in both groups, plus IADL difficulties in the dependence-excluded group. Being frail at baseline significantly predicted future ADL difficulties, IADL difficulties, and mortality in both groups, plus worse SPPB in the dependence-excluded group. Conclusion This study has validated the FRAIL scale in a late middle-aged African American population. This simple 5-question scale is an excellent screening test for clinicians to identify frail persons at risk of developing disability as well as decline in health functioning and mortality.

A phase 2 study of eculizumab for treating myasthenia gravis (MG) used the quantitative myasthenia gravis score (QMG) and myasthenia gravis activities of daily living profile (MG-ADL) to evaluate baseline disease severity and treatment response. Correlations were then analyzed between these assessments. Patients were given eculizumab or placebo during the first 16-week treatment period of the crossover study, with treatment assignments reversed for the second treatment period following a 5-week washout. QMG and MG-ADL scores at baseline and endpoint of each treatment period generated correlation coefficients for baseline status and treatment response during eculizumab therapy. Correlation strength between QMG and MG-ADL scores was higher for treatment response (R = 0.726; 95% confidence interval, 0.264-0.907; P = 0.0036) than for assessing baseline disease status (R = 0.552; 95% confidence interval, -0.022-0.839; P = 0.0495). MG-ADL may be more sensitive for assessing treatment response than point-in-time disease status. Muscle Nerve 56: 328-330, 2017. © 2016 Wiley Periodicals, Inc.

Continued care in patients with encephalitis and prolonged status epilepticus (SE) is controversial. Limited data is available on the functional and cognitive outcomes. In a prospective cohort study from 2007 to 2016, patients with acute encephalitis and SE were reviewed. Long-term outcomes including motor disability (modified Rankin Scale, mRS), daily living skills (activities of daily living, ADL), cognitive ability (modified Telephone Interview for Cognitive Status, TICS-M) and epilepsy sequelae, were evaluated in those survivors at 12-month follow-up. At the 12-month follow-up, 72 patients were recruited, who got a median score of 14 on the total ADL. 68% patients remained independent in their daily activities (mRS≤2). Post-SE symptomatic epilepsy was observed in 49% patients. 62 patients achieved a median score of 40 on the TICS-M and 14 on the TICS-M memory. Patients with autoimmune encephalitis were less prone to post-SE symptomatic epilepsy (18% vs. 58%, P=0.005) but lower TICS-M memory score than those with viral encephalitis (8.5 vs. 15, P=0.017). Compared to non-refractory status epilepticus (RSE), patients with RSE had a longer stay in NCU (39 vs. 26, P=0.002), more in-hospital complications and post-SE symptomatic epilepsy (67% vs. 33%, P=0.005). Long-term outcomes including ADL, mRS, and TICS-M were not significantly different between patients with RSE and non-RSE or between patients with long (≥4h) and short duration (<4h) of SE. Survival with favorable functional recovery was promising after prolonged RSE in patients with acute encephalitis. This article is protected by copyright. All rights reserved.

Background Stroke is a chronic disease. Standardized assessment is essential in order to determine areas for treatment. Individuals with aphasia are often excluded from research, because it is believed that their language impairments may impact their ability to provide informed consent. Thus, right spatial neglect could be under-diagnosed. Objective This study was developed to (1) determine the frequency of spatial neglect in chronic left-brain stroke survivors with aphasia, (2) determine the clinical utility of an aphasia-friendly consent form, and (3) determine any differences between neglect and no-neglect groups regarding activities of daily living (ADL) performance and community independence. Methods Forty-six people were consented at community center. Three were screen failures secondary to the exclusion criteria. A novel, aphasia-friendly consent form was developed to facilitate participation of individuals with aphasia. This enabled 93% or 40 out of the 43 recruited participants to be included in this study. The Behavioral Inattention Test-conventional and the Catherine Bergego Scale via Kessler Foundation Neglect Assessment Process (CBS via KF-NAP) were utilized to determine neglect. The Life Space Questionnaire was used to determine community mobility and independence. The Barthel Index (BI) was used for objective clarification of performance in ADL. Results Successful use of the consent form resulted in determination that five out of 40 (12.5%) met criteria for spatial neglect; (on the CBS via KF-NAP). The neglect group had lower scores on the Life Space, suggesting less community mobility and independence, however, it was not statistically significant (p = 0.16). Differences in BI scores were also not significant (p = .013) but the neglect group did have reduced independence. Conclusions This study demonstrates the need to administer functional neglect assessments in left-brain stroke and to include individuals with aphasia in research. PMID:27322860

Whether the combination of obesity and low muscle strength (dynapenic-obesity) would cause greater impairment of the activities of daily living (ADL)/instrumental activities of daily living (IADL) than obesity alone and low muscle strength alone (dynapenia) remains unclear. The aim of this study was to reveal the possible independent and additive effects of dynapenia and obesity on ADL/IADL disability in an older Chinese population. A cross-sectional study, including 616 community-dwelling older adults, was conducted in China from 2010 to 2012. Based on the World Health Organization Asian Criteria of Obesity and handgrip strength tertiles, 4 independent groups were identified as follows: nondynapenia/nonobesity, dynapenia alone, obesity alone, and dynapenic-obesity. The Katz Index of Independence in ADL was used to assess ADL disability, whereas 6 IADL items of the Older Americans Resources and Services (OARS) multidimensional functional assessment questionnaire were used to assess IADL disability. The prevalence of ADL and IADL disability was 21.1% and 28.9% in the dynapenic-obesity group, 15.5% and 22.6% in the dynapenia alone group, 13.1% and 19.6% in the obesity alone group, and 11.9% and 12.9% in the nondynapenia/nonobesity group, respectively. After adjusting for the covariates, in comparison with the dynapenic-obesity group, the adjusted odds ratios (95% confidence interval) for ADL disability were 0.36 (0.13-0.73) in the nondynapenia/nonobesity group, 0.51 (0.20-0.78) in the dynapenia-alone group, and 0.40 (0.11-0.61) in the obesity-alone group. The corresponding data for IADL disability were 0.55 (0.20-0.93), 0.82 (0.39-0.98), and 0.61 (0.30-0.91), respectively. Dynapenia, obesity, and dynapenic-obesity were associated with an increased risk of ADL/IADL disability. Dynapenic-obesity was associated with a greater risk of ADL/IADL disability in comparison with dynapenia or obesity alone. Copyright © 2014 American Medical Directors Association, Inc.

First metatarsophalangeal joint (MTPJ1) hemiarthroplasty using a novel synthetic cartilage implant was as effective and safe as MTPJ1 arthrodesis in a randomized clinical trial. We retrospectively evaluated operative time and recovery period for implant hemiarthroplasty (n=152) and MTPJ1 arthrodesis (n=50). Perioperative data were assessed for operative and anaesthesia times. Recovery and return to function were prospectively assessed with the Foot and Ankle Ability Measure (FAAM) Sports and Activities of Daily Living (ADL) subscales and SF-36 Physical Functioning (PF) subscore. Mean operative time for hemiarthroplasty was 35±12.3min and 58±21.5min for arthrodesis (p<0.001). Anaesthesia duration was 28min shorter with hemiarthroplasty (p<0.001). At weeks 2 and 6 postoperative, hemiarthroplasty patients demonstrated clinically and statistically significantly higher FAAM Sport, FAAM ADL, and SF-36 PF subscores versus arthrodesis patients. MTPJ1 hemiarthroplasty with a synthetic cartilage implant took less operative time and resulted in faster recovery than arthrodesis. III, Retrospective case control study.

Degenerative cervical spine diseases are common, and physiotherapy is widely used as an initial form of treatment. We aimed to analyse the effects of the initial sessions of physiotherapy for patients who were newly diagnosed with degenerative cervical spine disorders. A prospective series of 30 patients with newly diagnosed degenerative cervical spine disease were referred to our department and followed up for the initial two sessions of physiotherapy. The patients were assessed after each session. Outcome parameters studied included pain using a visual analogue scale (VAS), neck range of movements and activities of daily living (ADL). Our study subjects comprised mainly females (60%) in their fifties (46.7%) who worked as clerks or secretaries (53.3%). There was an improvement in the patients' pain score (VAS) from a median of 8 to 4 after two visits to the physiotherapists. Slight improvement in the neck range of movements was also observed. Marked improvement was seen in ADL, especially in the ability to carry heavy objects. Physiotherapy is an effective initial option for patients with newly presented degenerative cervical spine disease. The results of this study can be used to advise patients on the short-term benefits of physiotherapy.

The early cognitive continuum has been emphasized recently. We sought to characterize the functional and physical aspects of the cognitive continuum in subjects with no cognitive impairment (NCI), subjective cognitive impairment (SCI), nonamnestic (NA-MCI), and amnestic mild cognitive impairment (A-MCI). Furthermore, we identified the potential diagnostic utility of specific functional tasks. A total of 702 participants, aged ≥65 years and defined as NCI, SCI, NA-MCI, and A-MCI according to the original Petersen criteria, were included. They completed the Korean basic (K-ADL) and Instrumental Activities of Daily Living Scales (K-IADL) and the Performance-Oriented Mobility Assessment (POMA). Significant differences were observed between the different cognitive status groups in three items and total scores on the K-ADL, six items and total scores on the K-IADL and POMA. Controlling for confounding factors revealed that subjects from the A-MCI group performed poorly at bathing, shopping, handling money, and the sum of assorted functional items. These findings demonstrated the declining feature of functional and physical performance according to the cognitive continuum, with A-MCI being discriminative with respect to specific functional tasks as compared to milder cognitive statuses. © 2014 S.

The rapid development of intelligent assistive technology for replacing a human caregiver in assisting people with dementia performing activities of daily living (ADLs) promises in the reduction of care cost especially in training and hiring human caregiver. The main problem however, is the various kinds of sensing agents used in such system and is dependent on the intent (types of ADLs) and environment where the activity is performed. In this paper on overview of the potential of computer vision based sensing agent in assistive system and how it can be generalized and be invariant to various kind of ADLs and environment. We find that there exists a gap from the existing vision based human action recognition method in designing such system due to cognitive and physical impairment of people with dementia.

The Glittre Activities of Daily Living Test (ADL-Test) is a reliable functional status measurement for stable chronic obstructive pulmonary disease (COPD) patients in a laboratory setting. We aimed to adapt the test to the home setting (mADL-Test) and to follow-up the functional status recovery of post-exacerbation COPD patients included in a home hospitalization (HH) program. We assessed 17 exacerbated moderate-to-very-severe COPD patients in 3 home visits: at discharge to HH (V0), 10days (V10post) and 1month after discharge (V30post). Patients completed the mADL-Test (laps, VO2 and VE), COPD assessment test (CAT), London Chest ADL Test (LCADL), modified Medical Research Council (mMRC) and upper limb strength (handgrip). The number of laps of the mADL-Test (4, 5 and 5, P<.05), CAT (19, 12 and 12, P<.01), mMRC (2, 1.5 and 1, P<.01) and the self-care domain of the LCADL (6, 5 and 5, P<.01) improved during follow-up (V0, V10post and V30post, respectively). No significant changes were evidenced in VO2, VE or handgrip. Our results suggest that the mADL-test can be performed in the home setting after a COPD exacerbation, and that functional status continues to improve 10days after discharge to HH.

Currently, oxygen uptake () is the most precise means of investigating aerobic fitness and level of physical activity; however, can only be directly measured in supervised conditions. With the advancement of new wearable sensor technologies and data processing approaches, it is possible to accurately infer work rate and predict during activities of daily living (ADL). The main objective of this study was to develop and verify the methods required to predict and investigate the dynamics during ADL. The variables derived from the wearable sensors were used to create a predictor based on a random forest method. The temporal dynamics were assessed by the mean normalized gain amplitude (MNG) obtained from frequency domain analysis. The MNG provides a means to assess aerobic fitness. The predicted during ADL was strongly correlated (r = 0.87, P < 0.001) with the measured and the prediction bias was 0.2 ml·min−1·kg−1. The MNG calculated based on predicted was strongly correlated (r = 0.71, P < 0.001) with MNG calculated based on measured data. This new technology provides an important advance in ambulatory and continuous assessment of aerobic fitness with potential for future applications such as the early detection of deterioration of physical health.

The ADL-Glittre was created to assess more comprehensively the essential activities of daily living in adults with chronic obstructive pulmonary disease. The aim of this study was to validate the ADL-Glittre test adapted for children (TGlittre-P) and verify its reliability. This is a cross-sectional study with 87 healthy children aged 6 to 14 years (mean 10.36 ± 2.32 years). Biometric and spirometry data were collected from all participants. On the same day, part of the sample (36 children included in the validation process) performed two 6MWT and two TGlittre-P (30-minute interval between them). The other part of the sample just performed two TGlittre-P for the reliability process. Pearson and Spearman correlation tests were used to verify the correlation between the time spent on the TGlittre-P and the distance walked in the 6MWT. The intraclass correlation coefficient (ICC) was also used to assess the reproducibility of the TGlittre-P. The TGlittre-P showed a moderate negative correlation with the 6MWT (r = -0.490; p = 0.002; 95%CI -0.712 to -0.233). However, the behavior of the physiological variables that were monitored during the tests was similar and showed to be reproducible (ICC = 0.843; p = 0.000; 95%CI 0.695 to 0.911). The TGlittre-P proved to be a valid and reliable assessment of the functional capacity of healthy children aged 6 to 14 years.

Relationship between masticatory function and cognitive impairment had been suggested but still understudied. We investigated the association between chewing ability and cognitive impairment among the elderly living in a rural region. A total of 295 elderly individuals aged ≥70 years in a rural city of Korea participated in a cross-sectional study. Trained nurses conducted interviews and assessed chewing ability using gum that changed color based on chewing performance. Cognitive impairment was assessed using the Mini-Mental State Examination for Dementia Screening (MMSE-DS) of Korean vesrsion. Socio-demographic characteristics, activities of daily living (ADL), Mini-Nutritional Assessment (MNA) were also assessed using questionnaires as potential confounders. The mean age of the participants was 81.4 (ranged 70-102) years and 67.8% of them were female. Participants with low chewing ability were significantly older, dependent, and had lower MNA and MMSE-DS scores. The elderly with middle or low chewing ability had significantly higher risk for having cognitive impairment than those with higher chewing ability. Our findings suggest that poor chewing ability is associated with cognitive impairment or dementia in the elderly living in rural area. Copyright © 2017 Elsevier B.V. All rights reserved.

Functional range of motion of the hand joints in activities of the International Classification of Functioning, Disability and Health.

Gracia-Ibáñez, Verónica; Vergara, Margarita; Sancho-Bru, Joaquín L; Mora, Marta C; Piqueras, Catalina

Cross-sectional research design. Active range of motion (AROM) is used as indicator of hand function. However, functional range of motion (FROM) data are limited, and fail to represent activities of daily living (ADL). To estimate dominant hand FROM in flexion, abduction and palmar arching in people under 50 years of age performing ADL. AROMs and hand postures in 24 representative ADL of the International Classification of Functioning, Disability and Health (ICF) were recorded in 12 men and 12 women. FROM data were reported by activity and ICF area, and compared with AROMs. The relationship between ROM measures to gender and hand size was analyzed by correlation. FROM was 5° to 28° less than available AROM depending on the joint and movement performed. Joints do not necessarily move through full AROM while performing ADL which has benefits in retaining function despite loss of motion. This may also suggest that ADL alone are insufficient to retain or restore full AROM. Therapists should consider FROM requirements and normal AROM when defining hand therapy goals, interventions and evaluating the success of treatment. N/A. Copyright © 2016 Hanley & Belfus.

Abstract This article illuminates the major and often overlooked challenge of untethering soft robotic systems through the context of recent work, in which soft robotic gripper technology enabled by jamming of granular media was applied to a prosthetic jamming terminal device (PJTD). The PJTD's technical and market feasibility was evaluated in a pilot study with two upper-limb amputees. A PJTD prototype was tested against a commercial device (Motion Control electric terminal service with a one degree-of-freedom pinching mechanism) using two existing hand function tests: the first quantified the device's speed in picking and placing small blocks and the second evaluated a person's ability to perform activities of daily living (ADLs). The PJTD prototype performed slightly slower than its commercial counterpart in the first test. While both participants successfully completed all the ADLs with both devices in the second test, the commercial device scored marginally higher. Results suggested that PJTD can have potential benefits over existing terminal devices, such as providing the capability to firmly grasp tools due to the ability of PJTD to conform to arbitrary surfaces and reducing compensatory shoulder movements due to its axisymmetric design. Some downsides were that users reported fatigue while operating the PJTD, as most operations require pushing the PJTD against target objects to adequately conform to them. The greatest drawback for the PJTD is also a major roadblock preventing a number of soft robotic research projects from making an impact in real-world applications: pneumatic technology required for operating the PJTD is currently too large and heavy to enable compact untethered operation.

Objective Individuals with amnestic Mild Cognitive Impairment (MCI) have few empirically-based treatment options for combating their memory loss. This study sought to examine the efficacy of a calendar/notebook rehabilitation intervention, the Memory Support System (MSS), for individuals with amnestic MCI. Methods Forty individuals with single domain amnestic MCI and their program partners were randomized to receive the MSS, either with training or without (controls). Measures of adherence, activities of daily living, and emotional impact were completed at the first and last intervention session and again at 8-weeks and 6 months post intervention. Results Training in use of a notebook/calendar system significantly improved adherence over those who received the calendars but no training. Functional ability and memory self efficacy significantly improved for those who received MSS training. Change in functional ability remained significantly better in the intervention group than in the control group out to 8 week follow up. Care partners in the intervention group demonstrated improved mood by 8 week and 6 month follow-up, while control care partners reported worse caregiver burden by 6 month follow up. Conclusions MSS training resulted in improvement in ADLs and sense of memory self efficacy for individuals with MCI. While ADL benefits were maintained out to 8 weeks post intervention, future inclusion of booster sessions may help extend the therapeutic effect out even further. Improved mood of care partners of trained individuals and worsening sense of caregiver burden over time for partners of untrained individuals further supports the efficacy of the MSS for MCI.

Myasthenia gravis (MG) is an autoimmune neuromuscular disorder in which disabling muscle weakness may affect health-related quality of life (HRQoL). The aim of this study was to investigate which common motor-functional deficits and corresponding severity are most determinant of poor HRQoL in these patients. In 41 patients, the dichotomized first item of the Italian Myasthenia Gravis Questionnaire (IMGQ), categorizing patients who report "good" and "poor" HRQoL, was chosen as dependent-outcome variable. All items composing the myasthenia gravis-specific scale (MG-ADL), i.e. talking, chewing, swallowing, breathing, impairment of ability to brush teeth or comb hair, impairment of ability to rise from chair, double vision, and eyelid droop were acquired as independent variables and dichotomized. Stepwise backward LR multivariable logistic regression analysis was performed. In addition, the main characteristics of patients were compared. MG-ADL items "chewing" ≥1, i.e. "fatigue chewing solid food", and "breathing" ≥2, i.e. "shortness of breath at rest" proved to be significant determinants. Higher dose of corticosteroid therapy was significantly (p = 0.027; r s  = -0.35), correlated with poor HRQoL. At diagnosis, a decremental response to repetitive nerve stimulation (RNS) from the abductor pollicis brevis was significantly more frequent in patients with poor HRQoL. In conclusion, impaired "chewing" and "breathing" functions indicate the need for careful planning of rehabilitation, re-education and patient management. Moreover, decremental response to RNS at diagnosis may identify patients at risk for poor HRQoL.

Earlier studies in nursing homes show a high prevalence of cognitive impairment, dependency in activities of daily living (ADL), pain, and neuropsychiatric symptoms among residents. The aim of this study was to explore the prevalence of the above among residents in a nationally representative sample of Swedish nursing homes, and to investigate whether pain and neuropsychiatric symptoms differ in relation to gender, cognitive function, ADL-capacity, type of nursing-home unit and length of stay. Cross-sectional data from 188 randomly selected nursing homes were collected. A total of 4831 residents were assessed for cognitive and ADL function, pain and neuropsychiatric symptoms. Data were analysed using descriptive statistics and the chi-square test. The results show the following: the prevalence of cognitive impairment was 67 %, 56 % of residents were ADL-dependent, 48 % exhibited pain and 92 % exhibited neuropsychiatric symptoms. The prevalence of pain did not differ significantly between male and female residents, but pain was more prevalent among cognitively impaired and ADL-dependent residents. Pain prevalence was not significantly different between residents in special care units for people with dementia (SCU) and general units, or between shorter-and longer-stay residents. Furthermore, the prevalence of neuropsychiatric symptoms did not differ significantly between male and female residents, between ADL capacities or in relation to length of stay. However, residents with cognitive impairment and residents in SCUs had a significantly higher prevalence of neuropsychiatric symptoms than residents without cognitive impairment and residents in general units. The prevalence rates ascertained in this study could contribute to a greater understanding of the needs of nursing-home residents, and may provide nursing home staff and managers with trustworthy assessment scales and benchmark values for further quality assessment purposes, clinical development work and initiating future nursing assessments.

Disability Measurement for Korean Community-Dwelling Adults With Stroke: Item-Level Psychometric Analysis of the Korean Longitudinal Study of Ageing

2018-01-01

Objective To investigate the psychometric properties of the activities of daily living (ADL) instrument used in the analysis of Korean Longitudinal Study of Ageing (KLoSA) dataset. Methods A retrospective study was carried out involving 2006 KLoSA records of community-dwelling adults diagnosed with stroke. The ADL instrument used for the analysis of KLoSA included 17 items, which were analyzed using Rasch modeling to develop a robust outcome measure. The unidimensionality of the ADL instrument was examined based on confirmatory factor analysis with a one-factor model. Item-level psychometric analysis of the ADL instrument included fit statistics, internal consistency, precision, and the item difficulty hierarchy. Results The study sample included a total of 201 community-dwelling adults (1.5% of the Korean population with an age over 45 years; mean age=70.0 years, SD=9.7) having a history of stroke. The ADL instrument demonstrated unidimensional construct. Two misfit items, money management (mean square [MnSq]=1.56, standardized Z-statistics [ZSTD]=2.3) and phone use (MnSq=1.78, ZSTD=2.3) were removed from the analysis. The remaining 15 items demonstrated good item fit, high internal consistency (person reliability=0.91), and good precision (person strata=3.48). The instrument precisely estimated person measures within a wide range of theta (−4.75 logits < θ < 3.97 logits) and a reliability of 0.9, with a conceptual hierarchy of item difficulty. Conclusion The findings indicate that the 15 ADL items met Rasch expectations of unidimensionality and demonstrated good psychometric properties. It is proposed that the validated ADL instrument can be used as a primary outcome measure for assessing longitudinal disability trajectories in the Korean adult population and can be employed for comparative analysis of international disability across national aging studies.

Alzheimer's disease (AD) impairs cognitive functions, subsequently decreasing activity of daily living (ADL), and is frequently accompanied by lower limb fracture including hip fracture in the elderly. However, there have been few studies on what kinds of physical functions are affected or what degrees of dysfunction are produced by this combination. This study aims to clarify the relationship between decreased ADL and the combination of AD and lower limb fracture. We examined present illness and ADL in 4340 elderly aged 82.8 ± 9.36 years [average ± standard deviation (SD)] requiring nursing care and compared ADL between elderly with and without AD or lower limb fracture treated with surgery or conservatively using analysis of covariance (ANCOVA), with age and sex as covariants. We recognized that activities of cognitive function (p < 0.001), eating (dysphagia) (p < 0.001), eating (feeding) (p < 0.001), and toilet use (p < 0.001) in the elderly with AD were significantly lower than in those without the disease, even after adjusting for sex and age. Activities of bed mobility (p < 0.05), transfer and locomotion (p < 0.001), and bathing (p < 0.05) in the elderly with a fracture treated with surgery were significantly lower, which differed from the results of AD. Significant interactions of AD and fracture treated with surgery on the ADL scores for bed mobility (p < 0.001), dysphagia (p < 0.01), feeding (p < 0.001), and toilet use (p < 0.05) show that the combination had a much more profound influence on the ADL scores than AD or fracture alone. We obtained almost the same results for fractures treated conservatively as for fractures treated with surgery. These results demonstrated that the combined effects of AD and lower limb fracture were significantly greater than expected additive effects of AD and fracture, suggesting that the combination of AD and lower limb fracture has synergistic effects on almost all types of ADL except cognitive functions.

The life-long clinical information of any person supported by electronic means configures his Electronic Health Record (EHR). This information is usually distributed among several independent and heterogeneous systems that may be syntactically or semantically incompatible. There are currently different standards for representing and exchanging EHR information among different systems. In advanced EHR approaches, clinical information is represented by means of archetypes. Most of these approaches use the Archetype Definition Language (ADL) to specify archetypes. However, ADL has some drawbacks when attempting to perform semantic activities in Semantic Web environments. In this work, Semantic Web technologies are used to specify clinical archetypes for advanced EHR architectures. The advantages of using the Ontology Web Language (OWL) instead of ADL are described and discussed in this work. Moreover, a solution combining Semantic Web and Model-driven Engineering technologies is proposed to transform ADL into OWL for the CEN EN13606 EHR architecture.

The purpose of this study was to examine the effects of religiousness on the trajectories of difficulties with activities of daily living (ADLs) and instrumental ADLs (IADLs) in community-dwelling older adults over a three-year period. Seven waves of data from the University of Alabama at Birmingham Study of Aging were analyzed using a hierarchical linear modeling method. The study was based on the 784 participants who completed interviews every six months between December 1999 and February 2004. Frequent religious service attendance was associated with fewer ADL difficulties and IADL difficulties at baseline. Furthermore, religious service attendance predicted slower increases for frequent churchgoers and steeper increases for less frequent churchgoers in IADL difficulties, controlling for variables related to demographics and resources. Religious service attendance was independently associated with ADL and IADL difficulties cross-sectionally. However, significant protective effects of religious service attendance were identified longitudinally only for the IADL trajectory. PMID:20485460

Due to the boom of wireless handheld devices such as smartwatches and smartphones, wearable Fall Detection Systems (FDSs) have become a major focus of attention among the research community during the last years. The effectiveness of a wearable FDS must be contrasted against a wide variety of measurements obtained from inertial sensors during the occurrence of falls and Activities of Daily Living (ADLs). In this regard, the access to public databases constitutes the basis for an open and systematic assessment of fall detection techniques. This paper reviews and appraises twelve existing available data repositories containing measurements of ADLs and emulated falls envisaged for the evaluation of fall detection algorithms in wearable FDSs. The analysis of the found datasets is performed in a comprehensive way, taking into account the multiple factors involved in the definition of the testbeds deployed for the generation of the mobility samples. The study of the traces brings to light the lack of a common experimental benchmarking procedure and, consequently, the large heterogeneity of the datasets from a number of perspectives (length and number of samples, typology of the emulated falls and ADLs, characteristics of the test subjects, features and positions of the sensors, etc.). Concerning this, the statistical analysis of the samples reveals the impact of the sensor range on the reliability of the traces. In addition, the study evidences the importance of the selection of the ADLs and the need of categorizing the ADLs depending on the intensity of the movements in order to evaluate the capability of a certain detection algorithm to discriminate falls from ADLs.

To evaluate effects of early intensive physiotherapy during acute illness on post hospitalization activity daily living autonomy (ADL). Prospective randomized controlled trial of intensive physiotherapy rehabilitation on day 1 to 2 after admission until clinical stability or usual care. acute care geriatric medicine ward. A total of 76 acutely ill patients, acutely bedridden or with reduced mobility but who were autonomous for mobility within the previous 3 months. Patients in palliative care or with limiting mobility pathology were excluded. Mean age was 85.4 (SD 6.6) years. At admission, at clinical stability and one month later: anthropometry, energy and protein intakes, hand grip strength, ADL scores, and baseline inflammatory parameters. An exploratory principal axis analysis was performed on the baseline characteristics and general linear models were used to explore the course of ADL and nutritional variables. A 4-factor solution was found explaining 71.7% of variance with a factor "nutrition", a factor "function" (18.8% of variance) for ADL, handgrip strength, bedridden state, energy and protein intakes, serum albumin and C-reactive protein concentrations; a factor "strength" and a fourth factor . During follow-up, dietary intakes, handgrip strength, and ADL scores improved but no changes occurred for anthropometric variables. Intervention was associated only with an increase in protein intake. Better improvement in ADL was found in intervention group when model was adjusted on "function" factor items. Physical intervention programs should be proposed according to nutritional intakes with the aim of preventing illness induced disability.

People with central visual field loss (CFL) adopt various strategies to complete activities of daily living (ADL). Using objective movement analysis, we compared how three ADLs were completed by people with CFL compared with age-matched, visually healthy individuals. Fourteen participants with CFL (age 81 ± 10 years) and 10 age-matched, visually healthy (age 75 ± 5 years) participated. Three ADLs were assessed: pick up food from a plate, pour liquid from a bottle, and insert a key in a lock. Participants with CFL completed each ADL habitually (as they would in their home). Data were compared with visually healthy participants who were asked to complete the tasks as they would normally, but under specified experimental conditions. Movement kinematics were compared using three-dimension motion analysis (Vicon). Visual functions (distance and near acuities, contrast sensitivity, visual fields) were recorded. All CFL participants were able to complete each ADL. However, participants with CFL demonstrated significantly (P < 0.05) longer overall movement times, shorter minimum viewing distance, and, for two of the three ADL tasks, needed more online corrections in the latter part of the movement. Results indicate that, despite the adoption of various habitual strategies, participants with CFL still do not perform common daily living tasks as efficiently as healthy subjects. Although indices suggesting feed-forward planning are similar, they made more movement corrections and increased time for the latter portion of the action, indicating a more cautious/uncertain approach. Various kinematic indices correlated significantly to visual function parameters including visual acuity and midperipheral visual field loss.

The relationship between the chemical and molecular properties - in particular the (acid detergent) lignin (ADL) content and composition expressed as the ratio between syringyl and guaiacyl compounds (S:G ratio) - of maize stems and in vitro gas production was studied in order to determine which is more important in the degradability of maize stem cell walls in the rumen of ruminants. Different internodes from two contrasting maize cultivars (Ambrosini and Aastar) were harvested during the growing season. The ADL content decreased with greater internode number within the stem, whereas the ADL content fluctuated during the season for both cultivars. The S:G ratio was lower in younger tissue (greater internode number or earlier harvest date) in both cultivars. For the gas produced between 3 and 20 h, representing the fermentation of cell walls in rumen fluid, a stronger correlation (R 2 = 0.80) was found with the S:G ratio than with the ADL content (R 2 = 0.68). The relationship between ADL content or S:G ratio and 72-h gas production, representing total organic matter degradation, was weaker than that with gas produced between 3 and 20 h. The S:G ratio plays a more dominant role than ADL content in maize stem cell wall degradation. © 2017 The Authors.

We aimed to examine the concurrent effects of timing and intensity of rehabilitation on improving activities of daily living (ADL) among patients with ischemic stroke. Using the Japanese Diagnosis Procedure Combination inpatient database, we retrospectively analyzed consecutive patients with ischemic stroke at admission who received rehabilitation (n=100 719) from April 2012 to March 2014. Early rehabilitation was defined as that starting within 3 days after admission. The average rehabilitation intensity per day was calculated as the total units of rehabilitation during hospitalization divided by the length of hospital stay. A multivariable logistic regression analysis with multiple imputation and an instrumental variable analysis were performed to examine the association of early and intensive rehabilitation with the proportion of improved ADL score. The proportion of improved ADL score was higher in the early and intensive rehabilitation group. The multivariable logistic regression analysis showed that significant improvements in ADL were observed for early rehabilitation (odds ratio: 1.08; 95% confidence interval: 1.04-1.13; P <0.01) and intensive rehabilitation of >5.0 U/d (odds ratio: 1.87; 95% confidence interval: 1.69-2.07; P <0.01). The instrumental variable analysis showed that an increased proportion of improved ADL was associated with early rehabilitation (risk difference: 2.8%; 95% confidence interval: 2.0-3.4%; P <0.001) and intensive rehabilitation (risk difference: 5.6%; 95% confidence interval: 4.6-6.6%; P <0.001). The present results suggested that early and intensive rehabilitation improved ADL during hospitalization in patients with ischemic stroke. © 2017 American Heart Association, Inc.

Health literacy (HL) refers to the ability to obtain, process, and understand basic health information and services, and is thus needed to make appropriate health decisions. The Newest Vital Sign (NVS) is comprised of 6 questions about an ice cream nutrition label and assesses HL numeracy skills. We developed a Japanese version of the NVS (NVS-J) and evaluated the validity and reliability of the NVS-J in patients with chronic pain. The translation of the original NVS into Japanese was achieved as per the published guidelines. An observational study was subsequently performed to evaluate the validity and reliability of the NVS-J in 43 Japanese patients suffering from chronic pain. Factor analysis with promax rotation, using the Kaiser criterion (eigenvalues ≥1.0), and a scree plot revealed that the main component of the NVS-J consists of three determinative factors, and each factor consists of two NVS-J items. The criterion-related validity of the total NVS-J score was significantly correlated with the total score of Ishikawa et al.'s self-rated HL Questionnaire, the clinical global assessment of comprehensive HL level, cognitive function, and the Brinkman index. In addition, Cronbach's coefficient for the total score of the NVS-J was adequate (alpha = 0.72). This study demonstrated that the NVS-J has good validity and reliability. Further, the NVS-J consists of three determinative factors: "basic numeracy ability," "complex numeracy ability," and "serious-minded ability." These three HL abilities comprise a 3-step hierarchical structure. Adequate HL should be promoted in chronic pain patients to enable coping, improve functioning, and increase activities of daily living (ADLs) and quality of life (QOL).

Dementia is a multifaceted disorder that impairs cognitive functions, such as memory, language, and executive functions necessary to plan, organize, and prioritize tasks required for goal-directed behaviors. In most cases, individuals with dementia experience difficulties interacting with physical and social environments. The purpose of this study was to establish ecological validity and initial construct validity of a fire evacuation Virtual Reality Day-Out Task (VR-DOT) environment based on performance profiles as a screening tool for early dementia. The objectives were (1) to examine the relationships among the performances of 3 groups of participants in the VR-DOT and traditional neuropsychological tests employed to assess executive functions, and (2) to compare the performance of participants with mild Alzheimer's-type dementia (AD) to those with amnestic single-domain mild cognitive impairment (MCI) and healthy controls in the VR-DOT and traditional neuropsychological tests used to assess executive functions. We hypothesized that the 2 cognitively impaired groups would have distinct performance profiles and show significantly impaired independent functioning in ADL compared to the healthy controls. The study population included 3 groups: 72 healthy control elderly participants, 65 amnestic MCI participants, and 68 mild AD participants. A natural user interface framework based on a fire evacuation VR-DOT environment was used for assessing physical and cognitive abilities of seniors over 3 years. VR-DOT focuses on the subtle errors and patterns in performing everyday activities and has the advantage of not depending on a subjective rating of an individual person. We further assessed functional capacity by both neuropsychological tests (including measures of attention, memory, working memory, executive functions, language, and depression). We also evaluated performance in finger tapping, grip strength, stride length, gait speed, and chair stands separately and while performing VR-DOTs in order to correlate performance in these measures with VR-DOTs because performance while navigating a virtual environment is a valid and reliable indicator of cognitive decline in elderly persons. The mild AD group was more impaired than the amnestic MCI group, and both were more impaired than healthy controls. The novel VR-DOT functional index correlated strongly with standard cognitive and functional measurements, such as mini-mental state examination (MMSE; rho=0.26, P=.01) and Bristol Activities of Daily Living (ADL) scale scores (rho=0.32, P=.001). Functional impairment is a defining characteristic of predementia and is partly dependent on the degree of cognitive impairment. The novel virtual reality measures of functional ability seem more sensitive to functional impairment than qualitative measures in predementia, thus accurately differentiating from healthy controls. We conclude that VR-DOT is an effective tool for discriminating predementia and mild AD from controls by detecting differences in terms of errors, omissions, and perseverations while measuring ADL functional ability.

To investigate the influence of eyelid shape on tear film quality, ocular surface characteristics and dry eye symptomatology by comparing Asian and Caucasian populations. Seventy-four age-matched participants were recruited in a cross-sectional study. Participants were classified into Asian single lid (ASL), Asian double lid (ADL), and Caucasian double lid (CDL) groups. Dry eye symptomatology, ocular surface characteristics, and tear film quality were evaluated in a single clinical session. Meibomian gland dropout was significantly greater in both the ASL and ADL groups than in the CDL group (all P<.05). A greater proportion of ASL and ADL participants exhibited incomplete blinking than CDL patients (all P<.05). There were no significant differences in tear film quality and dry eye symptomatology between the three groups (all P>.05). Exposed ocular surface area, lissamine green staining, and lid wiper epitheliopathy were significantly greater in the ADL group compared to the CDL group (all P<.05). The CDL group displayed significantly greater anterior blepharitis and lid telangiectasia grades compared to both ASL and ADL groups (all P<.05). A higher degree of meibomian gland dropout and incomplete blinking was observed in both Asian groups compared to the Caucasian group, potentially predisposing these groups to dry eye.

Patients with stroke require additional support from family to live independently in the area of activities of daily living. Family members are usually the main caregivers of stroke patients. Comprehensive explanation of ADL handling from family caregivers' view is lacking. This study explores and describes family caregivers' experiences about the strategies to handle activities of daily living (ADL) dependency of elderly patient with stroke in the Iranian context. A qualitative content analysis approach was conducted to analyse data. Nineteen family caregivers participated in the study from multiple physiotherapy clinics of physiotherapy in Sari (Iran) between September 2013 and May 2014. Data were generated through in-depth interviews, and content analysis method was used to analyse the data and determine themes. The findings show that family caregivers manage the ADL dependency of their elderly stroke patients through seven strategies including encouraging physical movements, providing personal hygiene, nutritional consideration, facilitating religious activities, filling leisure time, and facilitating transfer and assisting in financial issues. Family has an important role in handling of elderly stroke patients' ADL dependency. Health practitioners can take benefit from the findings to help the stroke families play more active role in the handling ADL dependency of their patients after stroke. © 2016 Nordic College of Caring Science.

Amphetamine-like drugs are reported to enhance motor recovery and activities of daily living (ADL) in stroke rehabilitation, but results from trials with humans are inconclusive. This study is aimed at investigating whether levodopa (LD) and/or methylphenidate (MPH) in combination with physiotherapy could improve functional motor recovery and ADL in patients with stroke. A randomized, double-blind, placebo-controlled trial with ischemic stroke patients randomly allocated to one of four treatment groups of either MPH, LD or MPH+LD or placebo combined with physiotherapy was performed. Motor function, ADL, and stroke severity were assessed by Fugl-Meyer (FM), Barthel index (BI), and National Institute of Health Stroke Scale (NIHSS) at baseline, 15, 90, and 180 days respectively. All participants showed recovery of motor function and ADL during treatment and at 6-month follow-up. There were slightly but significant differences in BI and NIHSS compared to placebo at the 6-month follow-up. Ischemic chronic stroke patients having MPH and/or LD in combination with physiotherapy showed a slight ADL and stroke severity improvement over time. Future studies should address the issue of the optimal therapeutic window and dosage of medications to identify those patients who would benefit most. © 2010 John Wiley & Sons A/S.

Thalamic hemorrhages are associated with a variety of cognitive dysfunctions, and it is well known that such cognitive changes constitute a limiting factor of recovery of the activities of daily living (ADL). The relationship between cognitive dysfunction and hematomas is unclear. In this study, we investigated the relationship between aphasia/neglect and hematoma volume, hematoma type, and the ADL. One hundred fifteen patients with thalamic hemorrhage (70 men and 45 women) were studied. Their mean age was 68.9 ± 10.3 years, and patients with both left and right lesions were included. We calculated hematoma volume and examined the presence or absence of aphasia/neglect and the relationships between these dysfunctions and hematoma volume, hematoma type, and the ADL. Fifty-nine patients were found to have aphasia and 35 were found to have neglect. Although there was no relationship between hematoma type and cognitive dysfunction, hematoma volume showed a correlation with the severity of cognitive dysfunction. The ADL score and ratio of patient discharge for patients with aphasia/neglect were lower than those for patients without aphasia/neglect. We observed a correlation between the hematoma volume in thalamic hemorrhage and cognitive dysfunction. Aphasia/neglect is found frequently in patients with acute thalamic hemorrhage and may influence the ADL.

Physical activity levels are related through algorithms to the energetic demand, with no information regarding the integrity of the multiple physiological systems involved in the energetic supply. Longitudinal analysis of the oxygen uptake (V̇o 2 ) by wearable sensors in realistic settings might permit development of a practical tool for the study of the longitudinal aerobic system dynamics (i.e., V̇o 2 kinetics). This study evaluated aerobic system dynamics based on predicted V̇o 2 data obtained from wearable sensors during unsupervised activities of daily living (μADL). Thirteen healthy men performed a laboratory-controlled moderate exercise protocol and were monitored for ≈6 h/day for 4 days (μADL data). Variables derived from hip accelerometer (ACC HIP ), heart rate monitor, and respiratory bands during μADL were extracted and processed by a validated random forest regression model to predict V̇o 2 . The aerobic system analysis was based on the frequency-domain analysis of ACC HIP and predicted V̇o 2 data obtained during μADL. Optimal samples for frequency domain analysis (constrained to ≤0.01 Hz) were selected when ACC HIP was higher than 0.05 g at a given frequency (i.e., participants were active). The temporal characteristics of predicted V̇o 2 data during μADL correlated with the temporal characteristics of measured V̇o 2 data during laboratory-controlled protocol ([Formula: see text] = 0.82, P < 0.001, n = 13). In conclusion, aerobic system dynamics can be investigated during unsupervised activities of daily living by wearable sensors. Although speculative, these algorithms have the potential to be incorporated into wearable systems for early detection of changes in health status in realistic environments by detecting changes in aerobic response dynamics. NEW & NOTEWORTHY The early detection of subclinical aerobic system impairments might be indicative of impaired physiological reserves that impact the capacity for physical activity. This study is the first to use wearable sensors in unsupervised activities of daily living in combination with novel machine learning algorithms to investigate the aerobic system dynamics with the potential to contribute to models of functional health status and guide future individualized health care in the normal population.

The aim of this study was to verify the effects of functional-task training on cognitive function, activities of daily living (ADL) performance, and functional fitness in community-dwelling older adults with diagnosis of Alzheimer's disease (AD). A total of 57 participants (22 functional-task training group [FTG], 21 social gathering group [SGG], 14 control group [CG]) were recruited. Participants in both intervention groups carried out three 1-hr sessions per week of a functional-task program and social gathering activities for 12 weeks. Significant improvements were observed in executive functions (TMT, t-test, p = .03) in the SGG and in upper limb strength (arm curl, t-test, p = .01) in the FTG. Functional-task training has no significant effect on cognitive function, ADL, and functional fitness among people with AD, although it may contribute to slowing down the process of deterioration this illness causes.

Myasthenia gravis is an autoimmune disease of the neuromuscular junction, commonly affecting the ocular muscles. Cigarette smoking has been shown to influence many autoimmune diseases, including multiple sclerosis and rheumatoid arthritis, but its effect on myasthenia gravis has not been well studied. We sought to determine whether cigarette smoking influenced disease-related symptoms in ocular myasthenia gravis (OMG). We performed a prospective, clinic-based cross-sectional study in a single academic neuro-ophthalmology practice. All patients diagnosed with OMG between November 2006 and April 2014 were included. A prospective telephone survey was administered to determine smoking status and myasthenia gravis-related symptom severity. The main outcome measure was the myasthenia gravis-specific activities of daily living (MG-ADL) score, a well-validated marker of symptoms and quality of life in myasthenia gravis. Forty-four patients were included in the analysis. Comparison of MG-ADL ocular subscores between current smokers (3.4 ± 2.6), former smokers (1.8 ± 2.1), and never smokers (1.1 ± 1.5) revealed a statistically significant relationship (P = 0.031) where current smokers had the highest MG-ADL ocular subscores and never smokers the lowest. Comparison of MG-ADL total scores revealed the same relationship (current 5.6 ± 4.5, former 2.9 ± 3.1, never 1.4 ± 2.5, P = 0.003). There were borderline significant correlations of pack years with MG-ADL ocular subscore (r = 0.27, P = 0.074) and MG-ADL total score (r = 0.30, P = 0.051). Our findings indicate an association between cigarette smoking and symptom severity in OMG. This association suggests that smoking cessation in OMG patients may lead to improved symptom-related quality of life.

To evaluate the risk of incident physical disability and the decline in gait speed over a 6-year follow-up associated with a low ankle-arm index (AAI) in older adults. Observational cohort study. Forsyth County, North Carolina; Sacramento County, California; Washington County, Maryland; and Allegheny County, Pennsylvania. Four thousand seven hundred five older adults, 58% women and 17.6% black, participating in the Cardiovascular Health Study. AAI was measured in 1992/93 (baseline). Self-reported mobility, activity of daily living (ADL), and instrumental activity of daily living (IADL) disability and gait speed were recorded at baseline and at 1-year intervals over 6 years of follow-up. Mobility disability was defined as any difficulty walking half a mile and ADL and IADL disability was defined as any difficulty with 11 specific ADL and IADL tasks. Individuals with mobility, ADL, or IADL disability at baseline were excluded from the respective incident disability analyses. Lower baseline AAI values were associated with increased risk of mobility disability and ADL/IADL disability. Clinical cardiovascular disease (CVD), diabetes mellitus, and interim CVD events partially explained these associations for mobility disability and clinical CVD and diabetes mellitus partially explained these associations for ADL and IADL disability. Individuals with an AAI less than 0.9 had on average a mean decrease in gait speed of 0.02 m/s per year, or a decline of 0.12 m/s over the 6-year follow-up. Prevalent CVD partly explained this decrease but interim CVD events did not further attenuate it. Low AAI serves as marker of future disability risk. Reduction of disability risk in patients with a low AAI should consider cardiovascular comorbidity and the prevention of additional disabling CVD events.

This study was conducted to describe the functioning of Activities of Daily Living (ADL) and to examine socio-economic effects on ADL functioning among adults with intellectual disabilities (ID) aged 45 years and older (N=480) in Taiwan. The Barthel Index (BI) was used to determine a baseline level of ADL functioning in the study participants. There are five categories of functional impairment using the following cut-off values in Taiwan: total dependence (BI score 0-20), severe (BI score 21-60), moderate (BI score 61-90), mild (BI score 91-99), and total independence (BI score 100) (Taiwan Department of Health, 2012). The results revealed that 2.3% of adults with ID were in total dependence, 11.9% were in severe dependence, 27.9% were in moderate dependence, 8.1% had a mild dependence, and 49.8% were totally independent. In the multiple linear regression model of the ADL score, we determined that educational level, comorbid Down's syndrome, and disability level are the variables able to significantly predict ADL score (R(2)=0.190) after controlling for the factors of age, marital status, and other comorbidity conditions. Those ID adults with a lower education level (primary vs. literate, β=4.780, p=0.031; intermediate vs. literate, β=6.642, p=0.030), with comorbid Down's syndrome (β=-7.135, p=0.063), and with a more severe disability condition (severe vs. mild, β=-7.650, p=0.007; profound vs. mild, β=-19.169, p<0.001) had significantly lower ADL scores. The present study highlights the need to support mobility in older adults with ID as much as possible to optimize independence in this group. Copyright © 2013 Elsevier Ltd. All rights reserved.

2016-01-01

Brain Injury (BI) has become one of the most common causes of neurological disability in developed countries. Cognitive disorders result in a loss of independence and patients' quality of life. Cognitive rehabilitation aims to promote patients' skills to achieve their highest degree of personal autonomy. New technologies such as virtual reality or interactive video allow developing rehabilitation therapies based on reproducible Activities of Daily Living (ADLs), increasing the ecological validity of the therapy. However, the lack of frameworks to formalize and represent the definition of this kind of therapies can be a barrier for widespread use of interactive virtual environments in clinical routine. To provide neuropsychologists with a methodology and an instrument to design and evaluate cognitive rehabilitation therapeutic interventions strategies based on ADLs performed in interactive virtual environments. The proposed methodology is used to model therapeutic interventions during virtual ADLs considering cognitive deficit, expected abnormal interactions and therapeutic hypotheses. It allows identifying abnormal behavioural patterns and designing interventions strategies in order to achieve errorless-based rehabilitation. An ADL case study ('buying bread') is defined according to the guidelines established by the ADL intervention model. This case study is developed, as a proof of principle, using interactive video technology and is used to assess the feasibility of the proposed methodology in the definition of therapeutic intervention procedures. The proposed methodology provides neuropsychologists with an instrument to design and evaluate ADL-based therapeutic intervention strategies, attending to solve actual limitation of virtual scenarios, to be use for ecological rehabilitation of cognitive deficit in daily clinical practice. The developed case study proves the potential of the methodology to design therapeutic interventions strategies; however our current work is devoted to designing more experiments in order to present more evidence about its values.

We determined factors associated with self-reported decline in activities of daily living (ADLs) and symptoms of cognitive impairment in HIV positive adults in 5 European clinics. HIV+ adults underwent computerized and pen-and-paper neuropsychological tests and questionnaires of cognitive symptoms and ADLs. We considered cognitive function in 5 domains, psychosocial factors, and clinical parameters as potentially associated with symptoms. Separate regression analyses were used to determine factors associated with a decline in ADL (defined as self-reported decline affecting ≥2 ADLs and attributed to cognitive difficulties) and self-reported frequency of symptoms of cognitive impairment. We also estimated the diagnostic accuracy of both questionnaires as tests for cognitive impairment. Four hundred forty-eight patients completed the assessments [mean age 45.8 years, 84% male, 87% white, median CD4 count 550 cells/mm, median time since HIV diagnosis 9.9 years, 81% virologically suppressed (HIV-1 plasma RNA <50 copies/mL)]. Ninety-six (21.4%) reported decline in ADLs and attributed this to cognitive difficulties. Self-reported decline in ADLs and increased symptoms of cognitive impairment were both associated with worse performance on some cognitive tests. There were also strong associations with financial difficulties, depressive and anxiety symptoms, unemployment, and longer time since HIV diagnosis. Both questionnaires performed poorly as diagnostic tests for cognitive impairment. Patients' own assessments of everyday function and symptoms were associated with objectively measured cognitive function. However, there were strong associations with other psychosocial issues including mood and anxiety disorders and socioeconomic hardship. This should be considered when assessing HIV-associated cognitive impairment in clinical care or research studies.

Type 2 diabetes increases the risk of disability. The purpose of this study was to clarify the explanatory factors for disability in Japanese diabetic elderly. The 6-year decline in physical disability and functional limitations was investigated among 317 elderly people with type 2 diabetes recruited in a large-scale prospective study of the Japanese Elderly Diabetes Intervention Trial. Information about diabetes, blood examinations and complications was obtained, and basic activities of daily living (ADL) and instrumental ADL (IADL) were assessed by total score of the Barthel index and the Tokyo Metropolitan Institute of Gerontology Index of Competence, respectively. After 6 years of follow up, 13.6% of patients had developed a new ADL disability and 38.3% had developed a new functional impairment. In the 65-74 years age group, basic ADL decreased only in males, whereas females became functionally impaired. In the 75-84 years age group, basic and IADL decreased in both males and females. Older age and metabolic syndrome were prognostic for impairment of basic ADL, whereas baseline IADL problems, lower cognitive function, physical inactivity and insulin therapy were significant predictors of a future decline in the IADL. This study identified several factors predicting the future decline of basic ADL and IADL in diabetic elderly patients, and provided a conceptual framework that might help to clarify the pathways leading to disability. Because the specific causes of each functional problem are modifiable, comprehensive treatment and care are needed to allow Japanese diabetic elderly patients to have more favorable living conditions. © 2012 Japan Geriatrics Society.

OBJECTIVES To determine the cognitive and functional consequences of dual use of cholinesterase inhibitors (ChIs) and the bladder anticholinergics oxybutynin or tolterodine. DESIGN Prospective cohort study. SETTING Nursing homes (NHs) in the state of Indiana. PARTICIPANTS Three thousand five hundred thirty-six Medicaid-eligible NH residents aged 65 and older taking a ChI between January 1, 2003, and December 31, 2004. Residents were excluded if they were taking an anticholinergic other than oxybutynin or tolterodine. MEASUREMENTS Indiana Medicaid claims data were merged with data from the Minimum Data Set (MDS). Repeated-measures analyses were performed to assess the effects of dual therapy on change in cognitive function measured using the MDS Cognition Scale (MDS-COGS; scored 0–10) and change in activity of daily living (ADL) function using the seven ADL items in the MDS (scored 0–28). Potential covariates included age, sex, race, number of medications, and Charlson Comorbidity Index score. RESULTS Three hundred seventy-six (10.6%) residents were prescribed oxybutynin or tolterodine concomitantly with a ChI. In residents in the top quartile of ADL function, ADL function declined an average of 1.08 points per quarter when not taking bladder anticholinergics (ChI alone), compared with 1.62 points per quarter when taking dual therapy, a 50% greater rate in quarterly decline in ADL function (P =.01). There was no excess decline attributable to dual therapy in MDS-COGS scores or in ADL function for residents who started out with lower functioning. CONCLUSION In higher-functioning NH residents, dual use of ChIs and bladder anticholinergics may result in greater rates of functional decline than use of ChIs alone. The MDS-COGS may not be sensitive enough to detect differences in cognition due to dual use. PMID:18384584

ABSTRACT Background Airflow limitation frequently leads to the interruption of activities of daily living (ADL) in patients with Chronic Obstructive Pulmonary Disease (COPD). These patients commonly show absence of ventilatory reserve, reduced inspiratory reserve volume, and dynamic hyperinflation (DH). Objective To investigate ventilatory response and DH induced by three ADL-based protocols in COPD patients and compare them to healthy subjects. Method Cross-sectional study. COPD group: 23 patients (65±6 years, FEV1 37.2±15.4%pred); control group: 14 healthy subjects (64±4 years) matched for age, sex, and body mass index. Both groups performed all three tests: Glittre-ADL test; an activity test that involved moving objects on a shelf (TSHELF); and a modified shelf protocol isolating activity with upper limbs (TSHELF-M). Ventilatory response and inspiratory capacity were evaluated. Results Baseline ventilatory variables were similar between groups (p>0.05). The ventilatory demand increased and the inspiratory capacity decreased significantly at the end of the tests in the COPD group. Ventilatory demand and DH were higher (p<0.05) in the TSHELF than in the TSHELF–M in the COPD group (p<0.05). There were no differences in DH between the three tests in the control group (p>0.05) and ventilatory demand increased at the end of the tests (p<0.05) but to a lower extent than the COPD group. Conclusion The TSHELF induces similar ventilatory responses to the Glittre-ADL test in COPD patients with higher ventilatory demand and DH. In contrast, the ventilatory response was attenuated in the TSHELF-M, suggesting that squatting and bending down during the Glittre-ADL test could trigger significant ventilatory overload.

Background The associations of optimal levels of all major cardiovascular disease (CVD) risk factors, i.e., low-risk, in younger age with subsequent CVD morbidity and mortality have been well documented. However, little is known about associations of low-risk profiles in younger age with functional disability in older age. Methods and Results The sample included 6,014 participants from the CHA Study. Low-risk status, defined as untreated SBP/DBP ≤120/≤80 mmHg, untreated serum total cholesterol <5.18 mmol/l, not smoking, BMI < 25 kg/m2, and no diabetes, was assessed at baseline (1967–73). Functional disability, categorized as: 1) any disability in activities of daily living (ADLs), 2) any disability in instrumental ADLs (IADLs) but no ADL, or 3) no disability, was assessed from the 2003 health survey. There were 39% women, 4% Black, with a mean age of 43 and 6% low-risk status at baseline. After 32 years, 7% reported having limitations in performing any ADL and 11% in any IADL only. The prevalence of any ADL limitation was lowest in low-risk persons and increased in a graded fashion with less favorable risk-factor groups (p-trend <0.001). Compared to those with 2+ high-risk factors, the multivariable-adjusted odds of having any disability in ADLs vs. no disability in persons with low-risk, any moderate-risk, and 1 high-risk factor at baseline were lower by 58%, 48%, and 37%, respectively. Results were similar for IADLs, in both men and women. Conclusions Having an optimal CVD risk factor profile at younger age is associated with the lowest rate of functional disability in older age.

Background Activity limitations are an important and useful dimension of disability, but there are few validated measures of activity limitations for adolescents and adults with developmental disabilities. Objective/Hypothesis To describe the development of the Waisman Activities of Daily Living (W-ADL) Scale for adolescents and adults with developmental disabilities, and systematically evaluate its measurement properties according to an established set of criteria. Methods The W-ADL was administered among four longitudinally-studied groups of adolescents and adults with developmental disabilities: 406 with autism; 147 with fragile-X syndrome; 169 with Down syndrome, and 292 with intellectual disability of other or unknown origin. The W-ADL contains 17 activities and each is rated on a 3-point scale (0=“does not do at all”, 1=“does with help”, 2=“independent”), and a standard set of criteria were used to evaluate its measurement properties. Results Across the disability groups, Cronbach’s alphas ranged from 0.88 to 0.94, and a single-factor structure was most parsimonious. The W-ADL was reliable over time, with weighted kappas between 0.92 and 0.93. Criterion and construct validity were supported through substantial associations with the Vineland Screener, need for respite services, caregiving burden, and competitive employment. No floor or ceiling effects were present. There were significant group differences in W-ADL scores by maternally-reported level of intellectual disability (mild, moderate, severe, profound). Conclusions The W-ADL exceeded the recommended threshold for each quality criterion the authors evaluated. This freely-available tool is an efficient measure of activities of daily living for surveys and epidemiological research concerning adolescents and adults with developmental disabilities.

OBJECTIVE. Alzheimer’s disease (AD) results in a loss of independence in activities of daily living (ADLs), which in turn affects the quality of life of affected people and places a burden on caretakers. Limited research has examined the influence of physical training (aerobic, balance, and strength training) on ADL performance of people with AD. METHOD. Six randomized controlled trials (total of 446 participants) fit the inclusion criteria. For each study, we calculated effect sizes for primary and secondary outcomes. RESULTS. Average effect size (95% confidence interval) for exercise on the primary outcome (ADL performance) was 0.80 (p < .001). Exercise had a moderate impact on the secondary outcome of physical function (effect size = 0.53, p = .004). CONCLUSION. Occupational therapy intervention that includes aerobic and strengthening exercises may help improve independence in ADLs and improve physical performance in people with AD. Additional research is needed to identify specific components of intervention and optimal dosage to develop clinical guidelines. PMID:24367955

The Glittre activities of daily living (ADL) test is supposed to evaluate the functional capacity of COPD patients. The physiological requirements of the test and the time taken to perform it by COPD patients in different disease stages are not well known. The objective of this work was to compare the metabolic, ventilatory, and cardiac requirements and the time taken to carry out the Glittre ADL test by COPD subjects with mild, moderate, and severe disease. Spirometry, Medical Research Council questionnaire, cardiopulmonary exercise test, and 2 Glittre ADL tests were evaluated in 62 COPD subjects. Oxygen uptake (V̇ O 2 ), carbon dioxide production, pulmonary ventilation, breathing frequency, heart rate, S pO 2 , and dyspnea were analyzed before and at the end of the tests. Maximum voluntary ventilation, Glittre peak V̇ O 2 /cardiopulmonary exercise test (CPET) peak V̇ O 2 , Glittre V̇ E /maximum voluntary ventilation, and Glittre peak heart rate/CPET peak heart rate ratios were calculated to analyze their reserves. Subjects carried out the Glittre ADL test with similar absolute metabolic, ventilatory, and cardiac requirements. Ventilatory reserve decreased progressively from mild to severe COPD subjects ( P < .001 for Global Initiative for Chronic Obstructive Lung Disease [GOLD] 1 vs GOLD 2, P < .001 for GOLD 1 vs GOLD 3, and P < .001 for GOLD 2 vs GOLD 3). Severe subjects with COPD presented a significantly lower metabolic reserve than the mild and moderate subjects ( P = .006 and P = .043, respectively) and significantly lower Glittre peak heart rate/CPET peak heart rate than mild subjects ( P = .01). Time taken to carry out the Glittre ADL test was similar among the groups ( P = .82 for GOLD 1 vs GOLD 2, P = .19 for GOLD 1 vs GOLD 3, and P = .45 for GOLD 2 vs GOLD 3). As the degree of air-flow obstruction progresses, the COPD subjects present significant lower ventilatory reserve to perform the Glittre ADL test. In addition, metabolic and cardiac reserves may differentiate the severe subjects. These variables may be better measures to differentiate functional performance than Glittre ADL time.

Successful aging in centenarians: myths and reality.

Motta, M; Bennati, E; Ferlito, L; Malaguarnera, M; Motta, L

2005-01-01

The term "successful aging" appeared in the first issue of "The Gerontologist" in 1961. During the successive years, this expression has changed its meaning. Nowadays, successful aging means "absence of diseases and disabilities, maintenance of high levels of physical and cognitive abilities, preservation of the social and productive activities". It has become a common opinion that the centenarians may represent the prototypes of the successful aging. This motivated our work to study the clinical, psychical, and functional aspects in a centenarian group, verifying the real autonomy, instrumental capacities, and working abilities. Our study pool consisted of 602 centenarians, who were also subjects of then epidemiological studies of the Italian Multicenter Studies on Centenarians (IMUSCE). All subjects underwent a clinical-anamnestic evaluation, cognitive-functional tests by means of the mini mental state examination (MMSE), the independence index in activities of daily living (ADL), the instrumental activities of daily living (IADL) scale. The centenarians were classified in three groups, according to the criteria elaborated previously by us, based on their psychophysical status and autonomy, as follows. Group A: centenarians in good health status; Group B: centenarians in an intermediate health status. Group C: centenarians in bad health status. Group A represented 20.0% of the total pool, Group B amounted to 33.4%, and the Group C was 46.6%. The centenarians of Group A presented normal ADL values, and 47.9% of them were autosufficient in all functions; 5.7% of them were independent in all IADL items. These data confirm that the centenarians of Group A are free of invalidating chronic diseases, are autonomous, maintain good physical and cognitive capacities, however, have not maintained any social or productive activities. Therefore, they cannot be considered as prototypes of successful aging.

The purpose of this study was to design a repeatable universal rehabilitation program in which patients with hemiplegia can participate voluntarily, complementing physical and occupational therapies to increase voluntary exercise practice rate. Also, this study attempted to identify the relationship between psychological resilience due to the implementation of self-bedside exercise and functional recovery of activity of daily living (ADL). 12 patients with hemiplegia voluntarily participated in 8 weeks of self-bedside exercise 5 times a day and more than 5 days a week. Their program implementation, resilience, activities of daily living (MBI), upper limb motor functions (MFT), and balance ability (BBS) were analyzed and compared before and after the program. Compared to before implementing the program, significant increases were found in resilience, MBI, BBS, and MFT in the affected side after the implementation, and the resilience scores showed statistically positive correlation in MBI and MFT. Also, the change in resilience before and after the program implementation showed a statistically positive correlation. Therefore, it can be concluded that the self-bedside exercise developed in this study had a positive effect on voluntary participation in exercise as well as resilience and ADL. However, many studies which complement the psychological aspects of hemiparetic patients with stroke are still needed. PMID:25830141

Current rehabilitation for persons with hemiparesis after stroke requires high numbers of repetitions to be in accordance with contemporary motor learning principles. The motivational characteristics of computer games can be harnessed to create engaging interventions for persons with hemiparesis after stroke that incorporate this high number of repetitions. The purpose of this case report was to test the feasibility of using computer games as a 6-week home therapy intervention to improve upper extremity function for a person with stroke. One person with left upper extremity hemiparesis after stroke participated in a 6-week home therapy computer game intervention. The games were customized to her preferences and abilities and modified weekly. Her performance was tracked and analyzed. Data from pre-, mid-, and postintervention testing using standard upper extremity measures and the Reaching Performance Scale (RPS) were analyzed. After 3 weeks, the participant demonstrated increased upper extremity range of motion at the shoulder and decreased compensatory trunk movements during reaching tasks. After 6 weeks, she showed functional gains in activities of daily living (ADLs) and instrumental ADLs despite no further improvements on the RPS. Results indicate that computer games have the potential to be a useful intervention for people with stroke. Future work will add additional support to quantify the effectiveness of the games as a home therapy intervention for persons with stroke.

To characterize a spinal cord injury (SCI) population from the 2008 Sichuan earthquake in China; to evaluate functional outcomes of physical rehabilitation interventions; to assess potential determinants of rehabilitation effectiveness; and to assess medical complications and management outcomes. A total of 51 earthquake victims with SCI were enrolled and underwent rehabilitation programming. Functional rehabilitation outcomes included ambulation ability, wheelchair mobility and activities of daily living (ADL) assessed with the Modified Barthel Index at the beginning and end of rehabilitation. Effectiveness of rehabilitation and the effect of other predictors were evaluated by mixed effects regression. Outcomes of medical complication management were determined by comparison of the incidence of respective complications at the beginning and end of rehabilitation. Ambulation, wheelchair mobility and ADL were significantly improved with rehabilitation programming. Both earlier rescue and earlier onset of rehabilitation were significant positive predictors of rehabilitation effectiveness, whereas delayed onset of rehabilitation combined with prolonged time to rescue resulted in a lesser positive effect. Medical complications were managed effectively in 63% (pressure ulcers) to 85% (deep vein thrombosis) of patients during rehabilitation. Earthquake victims with SCI may achieve significantly improved functional rehabilitation functional outcomes on a formal, institutional-based physical rehabilitation programme.

Nursing facility patients are a population that has not been well studied with regard to functional status and independence previously. As such, the manner in which activities of daily living (ADL) relate to one another is not well understood in this population. An understanding of ADL difficulty ordering has helped to devise systems of functional independence grading in other populations, which have value in understanding patients' global levels of independence and providing expectations regarding changes in function. This study seeks to examine the hierarchy of ADL in the nursing facility population. Data were analyzed from the 2004 National Nursing Home Survey, a cross-sectional data set of 13 507 skilled nursing facility subjects with functional independence items. The ADL difficulty hierarchy was determined using Rasch analysis. Item fit values for the Rasch model using Mean-Square infit statistics were also determined. The robustness of the hierarchy was tested for each ADL. Two grading systems were devised from the results of the item difficulty ordering. One was based on the most difficult item that he or she could perform, and the other assigned a grade based on the least difficult item that a subject could not perform. A total of 13 113 patients were included in this analysis, the majority of whom were female and white. They had an average age of 81 years. An ordered hierarchy of ADL was found with eating being the easiest and bathing the most difficult. All items in the Katz index fit the Rasch model adequately well. The majority of patients able to perform any particular ADL were also able to perform all easier ADL. Cohen's κ for the 2 grading systems was 0.73. This study is the first to show the expected hierarchy of difficulty of the 6 activities of daily proposed in the Katz index in the nursing facility population. The hierarchy found in this population matches the original hierarchy found in older adults in the community and acute care settings. It is also similar to hierarchy found in the inpatient rehabilitation setting. Patients would be expected to lose or gain function based on the order of difficulty, but this remains to be confirmed. Among the 6 activities of daily living tested here, their order from easiest to most difficult is eating, maintaining continence, transferring, toileting, dressing, and bathing. In addition, the index formed by these 6 items has construct validity in the nursing facility population.

Frailty is a predictor of disability. A proper understanding of the contribution of individual indicators of frailty in the prediction of disability is a requisite for preventive interventions. The aim of this study was to determine the predictive power of the individual physical frailty indicators: gait speed, physical activity, hand grip strength, Body Mass Index (BMI), fatigue, and balance, for ADL and IADL disability. The sample consisted of 505 community-dwelling persons (≥75 years, response rate 35.1%). Respondents first participated between November 2007 and June 2008, and a subset of all respondents participated again one year later (N = 264, 52.3% response rate). ADL and IADL disability were assessed by the Groningen Activity Restriction Scale. BMI was assessed by self-report, and the other physical frailty indicators were assessed with the TUG test (gait speed), the LAPAQ (physical activity), a hand grip strength test, the SFQ (fatigue), and the Four-test balance scale. All six physical frailty indicators were associated with ADL and IADL disability. After controlling for previous disability, sociodemographic characteristics, self-perceived lifestyle, and chronic diseases, only gait speed was predictive of both ADL and IADL disability, whereas there was a small effect of fatigue on IADL disability. Hence, these physical frailty indicators should be included in frailty assessment when predicting future disability. PMID:24782894

Acquired brain injury (ABI) refers to multiple disabilities arising from damage to the brain acquired after birth. Children with an ABI may experience physical, cognitive, social and emotional-behavioural impairments which can impact their ability to participate in activities of daily living (ADL). Recent developments in technology have led to the emergence of internet-delivered therapy programs. "Move it to improve it" (Mitii™) is a web-based multi-modal therapy that comprises upper limb (UL) and cognitive training within the context of meaningful physical activity. The proposed study aims to compare the efficacy of Mitii™ to usual care to improve ADL motor and processing skills, gross motor capacity, UL and executive functioning in a randomised waitlist controlled trial. Sixty independently ambulant children (30 in each group) at least 12 months post ABI will be recruited to participate in this trial. Children will be matched in pairs at baseline and randomly allocated to receive either 20 weeks of Mitii™ training (30 min per day, six days a week, with a potential total dose of 60 h) immediately, or be waitlisted for 20 weeks. Outcomes will be assessed at baseline, immediately post-intervention and at 20 weeks post-intervention. The primary outcomes will be the Assessment of Motor and Process Skills and 30 s repetition maximum of functional strength exercises (sit-to-stand, step-ups and half kneel to stand). Measures of body structure and functions, activity, participation and quality of life will assess the efficacy of Mitii™ across all domains of the International Classification of Functioning, Disability and Health framework. A subset of children will undertake three tesla (3T) magnetic resonance imaging scans to evaluate functional neurovascular changes, structural imaging, diffusion imaging and resting state functional connectivity before and after intervention. Mitii™ provides an alternative approach to deliver intensive therapy for children with an ABI in the convenience of the home environment. If Mitii™ is found to be effective, it may offer an accessible and inexpensive intervention option to increase therapy dose. ANZCTR12613000403730.

The aim of the study was to evaluate the usefulness of the Polish version of the Care Dependency Scale (CDS) in predicting care needs and health risks of elderly patients admitted to a geriatric unit. This was a cross-sectional study of 200 geriatric patients aged ≥60 years, chronologically admitted to a geriatrics unit in Poland. The study was carried out using the Polish version of the CDS questionnaire to evaluate biopsychosocial needs and the level of care dependency. The mean age of the participating geriatric patients was 81.8±6.6. The mean result of the sum of the CDS index for all the participants was 55.3±15.1. Detailed analysis of the results of evaluation of the respondents' functional condition showed statistically significant differences in the levels of care dependency. Evaluation of the patients' physical performance in terms of the ability to do basic activities of daily living (ADL) and instrumental ADL (I-ADL) showed statistically significant differences between the levels of care dependency. Patients with high dependency were more often prone to pressure ulcers - 13.1±3.3, falls (87.2%), poorer emotional state - 6.9±3.6, mental function - 5.1±2.8, and more often problems with locomotion, vision, and hearing. The results showed that locomotive disability, depression, advanced age, and problem with vision and hearing are connected with increasing care dependency. CDS evaluation of each admitted geriatric patient enables us to predict the care needs and health risks that need to be reduced and the disease states to be improved. CDS evaluation should be accompanied by the use of other instruments and assessments to evaluate pressure ulcer risk, fall risk, and actions toward the improvement of subjective well-being, as well as correction of vision and hearing problems where possible and assistive devices for locomotion.

To assess the association between total insulinlike growth factor (IGF)-1, IGF binding protein-1 (IGFBP-1), and IGFBP-3 levels and functioning and mortality in older adults. Cohort study. One thousand one hundred twenty-two individuals aged 65 and older without prior cardiovascular disease events participating in the Cardiovascular Health Study. Baseline fasting plasma levels of IGF-1, IGFBP-1, and IGFBP-3 (defined as tertiles, T1-T3) were examined in relationship to handgrip strength, time to walk 15 feet, development of new difficulties with activities of daily living (ADLs), and mortality. Higher IGFBP-1 predicted worse handgrip strength (P-trend(T1-T3)<.01) and slower walking speed (P-trend(T1-T3)=.03), lower IGF-1 had a borderline significant association with worse handgrip strength (P-trend(T1-T3)=.06), and better grip strength was observed in the middle IGFBP-3 tertile than in the low or high tertiles (P=.03). Adjusted for age, sex, and race, high IGFBP-1 predicted greater mortality (P-trend(T1-T3)<.001, hazard ratio (HR)(T3vsT1)=1.48, 95% confidence interval (CI)=1.15-1.90); this association was borderline significant after additional confounder adjustment (P-trend(T1-T3)=.05, HR(T3vsT1)=1.35, 95% CI=0.98-1.87). High IGFBP-1 was associated with greater risk of incident ADL difficulties after adjustment for age, sex, race, and other confounders (P-trend(T1-T3)=.04, HR(T3vsT1)=1.40, CI=1.01-1.94). Neither IGF-1 nor IGFBP-3 level predicted mortality or incident ADL difficulties. In adults aged 65 and older, high IGFBP-1 levels were associated with greater risk of mortality and poorer functional ability, whereas IGF-1 and IGFBP-3 had little association with these outcomes.

A randomized clinical trial. Rehabilitation treatments for improving fine motor skills (FMS) in hand osteoarthritis (HOA) have not been well explored yet. To assess the effectiveness of a rehabilitation program on upper limb disability, independence of activities of daily living (ADLs), fine motor abilities, functional independency, and general self-efficacy in older adults with HOA. About 45 adults (74-86 years) with HOA were assigned to an experimental group for completing an FMS intervention or a control group receiving conventional occupational therapy. Both interventions were performed 3 times/wk, 45 minutes each session, during 8 weeks. Upper limb disability, performance in ADLs, pinch strength, manual dexterity, range of fingers motion, functional independency, and general self-efficacy were assessed at baseline, immediately after treatment, and after 2 months of follow-up. FMS group showed significant improvements with a small effect size on manual dexterity (P ≤ .034; d ≥ 0.48) and a moderate-high effect on range of index (P ≤ .018; d ≥ 0.58) and thumb (P ≤ .027; d ≥ 0.39) motion. The control group showed a significant worse range of motion over time in some joints at the index (P ≤ .037; d ≥ 0.36) finger and thumb (P ≤ .017; d ≥ 0.55). A rehabilitation intervention for FMS may improve manual dexterity and range of fingers motion in HOA, but its effects on upper limb disability, performance in ADLs, pinch strength, functionality, and self-efficacy remain uncertain. Specific interventions of the hand are needed to prevent a worsening in range of finger motion. 1b. Copyright © 2016 Hanley & Belfus. Published by Elsevier Inc. All rights reserved.

The purpose of this follow-up one and four years post stroke was to find out whether the initial physiotherapy approach had had any long-term effects on mortality, motor function, postural control, activities of daily living, life quality, follow-up from community services and living conditions. A randomized controlled trial of first time ever stroke patients. Group 1 (n = 33) and group 2 (n = 28) had initial physiotherapy according to the Motor Relearning Programme and Bobath, respectively. The Motor Assessment Scale (MAS), the Sødring Motor Evaluation Scale (SMES), the Barthel ADL Index, the Nottingham Health Profile (NHP) and Berg Balance Scale were used. The following parameters were also registered: incidence of new strokes, other diseases, use of assistive devices, the patient's accommodation and use of services from the community. The mortality rates were similar in the two groups. In both groups the motor function, postural control and ADL had decreased rapidly, leaving many of the patients dependent and with a high risk of falling. Life quality had increased compared to the acute stage, but was still low in comparison with healthy persons. Patients in both groups lived at home, but were dependent on help from relatives and community services. Physiotherapy as follow-up service was seldom used. The initial physiotherapy approach did not seem to have a major influence on the patients' ability to cope in the long-term. This follow-up at one and four years post stroke showed no major influence of two different initial physiotherapy regimens on long-term function. The study confirmed a rapid deterioration of ADL and motor function and an increased dependence on relatives. The study reveals a gap between the intense treatment in the acute phase and little or no follow-up of physiotherapy treatment or other rehabilitation activities later.

Background and Purpose Mental practice (MP), which involves cognitive rehearsal of physical movements, is a non-invasive, inexpensive method of enabling repetitive, task specific practice (RTP). Recent, randomized controlled data suggest that MP, when combined with a RTP therapy program, increases affected arm use and function significantly more than RTP only. As a next step, this 10-subject case series examined the possibility that cortical plasticity is a mechanism underlying the treatment effect of MP when combined with RTP. Method 10 chronic stroke patients (mean = 36.7 months) exhibiting stable, moderate motor deficits received ½ hour therapy sessions for their affected arms, occurring 3 days/week for 10 weeks, and emphasizing valued activities of daily living (ADLs). Directly after therapy, subjects received 30-minute MP sessions, which required MP of the ADLs performed during therapy. Behavioral outcomes were blindly evaluated using the Action Research Arm Test (ARAT) and the Fugl-Meyer Assessment (FM). Functional magnetic resonance imaging (fMRI) was administered before and after intervention to assess cortical changes. Results Before intervention, subjects exhibited stable motor deficits. After intervention, subjects exhibited marked ARAT and FM score increases (+ 5.3 and + 4.2, respectively), and clinically significant, new abilities to perform valued ADLs. Post-intervention fMRI revealed significant increases in activation to wrist flexion and extension of the affected hand in the premotor area and primary motor cortex ipsi- and contralaterally to the affected hand, and superior parietal cortex ipsilateral to the affected hand. Decreased activations were noted in parietal cortex of the hemisphere ipsilateral to the affected hand. These changes correlated with anatomical regions in which behavioral changes were observed via the ARAT and FM. Conclusions MP is an easy to use, cost effective strategy that was again shown to improve affected arm outcomes after stroke. This is the first study suggesting alteration in the cortical map as a possible MP mechanism for the affected arm. PMID:19155350

Prospective memory (PM) is the ability to remember to do something in the future without explicit prompts. Extending the number of subjects and the scope of our previously published study, this investigation examined the relationship between PM and socio-demographic and clinical factors, activities of daily living (ADL) and frontal lobe functions in patients with chronic schizophrenia. One hundred and ten Chinese schizophrenia patients, 60 from the previous study and 50 additional patients recruited for this study, and 110 matched healthy comparison subjects (HC) formed the study sample. Patients' clinical condition and activity of daily living were evaluated with the Brief Psychiatric Rating Scale (BPRS) and the Functional Needs Assessment (FNA). Time- and event-based PM tasks and three tests of prefrontal lobe functions (Design Fluency Test [DFT], Tower of London [TOL], Wisconsin Card Sorting Test [WCST]) were also administered. Patients' level of ADL and psychopathology were not associated with PM functions and only anticholinergic medications (ACM) showed a significant negative correlational relationship with PM tasks. Confirming the findings of the previous study, patients performed significantly more poorly on all two PM tasks than HC. Performance on time-based PM task significantly correlated with age, education level and DFT in HC and with age, DFT, TOL and WCST in patients. Patients' performance on the event-based PM correlated with DFT and one measure of WCST. In patients, TOL and age predicted the performance on time-based PM task; DFT and WCST predicted the event-based task. Involving a large sample of patients with matched controls, this study confirmed that PM is impaired in chronic schizophrenia. Deficient PM functions were related to prefrontal lobe dysfunction in both HC and patients but not to the patients' clinical condition, nor did they significantly affect ADL. ACMs determined certain aspects of PM.

Containerless processing by levitation technique has been extensively used for material science and engineering because it suppresses inhomogeneous nucleation from the container wall and helps to produce stable, metastable and glass phases. The containerless levitation technique is widely explored for material processing because of its technological and scientific advantages. Recently, research on bulk glass and glass-ceramics have attracted the attention of material scientists as they are considered as low cost optical materials of the future. In the present study, the formation of bulk spherical glass and crystalline ReAlO _{3}(Re=La-Lu,Y) phases has been investigated due to their unique features in terms of the solidification process from an undercooled melt, glass structure and optical properties. An Aerodynamic levitation (ADL) was used to undercool the melt well below the melting temperature. Sintered bits of ReAlO _{3} sample with a diameter of ~2.5 mm and mass of ~20-25 mg was levitated by an ADL and completely melted by a CO _{2} laser and then the droplet was cooled by turning off the CO _{2} laser and solidified. The surface temperature and solidification process of the levitated droplet was monitored using pyrometer and high speed video camera, respectively. Among the rare earth aluminum perovskites Lanthanum, Neodymium and samarium aluminum perovskites solidified as glass and others YAlO _{3} and Europium to Lutetium aluminum perovskites solidified as crystalline phases. The scanning electron microscopy (SEM) images of cross-sectioned samples, TG/DTA, Transmittance and Refractive Index studies were performed for both glass and crystalline phases. The results of the above studies revealed the formation of glass and crystalline phases directly from the undercooled melt. The glass transition temperature (Tg) gradually increased with increasing ionic radius of the rare-earth elements. The NdAlO _{3} glass phase showed a high refractive index of ~1.89, suggesting that containerless levitation is an elegant technique for fabrication of new glass and crystalline ceramics from an undercooled melt.

A study was conducted to investigate the criterion validity of measures of upper extremity (UE) motor function derived during practice of virtual activities of daily living (ADLs). Fourteen hemiparetic stroke patients employed a Virtual Occupational Therapy Assistant (VOTA), consisting of a high-fidelity virtual world and a Kinect™ sensor, in four sessions of approximately one hour in duration. An Unscented Kalman Filter-based human motion tracking algorithm estimated UE joint kinematics in real-time during performance of virtual ADL activities, enabling both animation of the user’s avatar and automated generation of metrics related to speed and smoothness of motion. These metrics, aggregated over discrete sub-task elements during performance of virtual ADLs, were compared to scores from an established assessment of UE motor performance, the Wolf Motor Function Test (WMFT). Spearman’s rank correlation analysis indicates a moderate correlation between VOTA-derived metrics and the time-based WMFT assessments, supporting the criterion validity of VOTA measures as a means of tracking patient progress during an UE rehabilitation program that includes practice of virtual ADLs.

OBJECTIVE. Alzheimer's disease (AD) results in a loss of independence in activities of daily living (ADLs), which in turn affects the quality of life of affected people and places a burden on caretakers. Limited research has examined the influence of physical training (aerobic, balance, and strength training) on ADL performance of people with AD. METHOD. Six randomized controlled trials (total of 446 participants) fit the inclusion criteria. For each study, we calculated effect sizes for primary and secondary outcomes. RESULTS. Average effect size (95% confidence interval) for exercise on the primary outcome (ADL performance) was 0.80 (p < .001). Exercise had a moderate impact on the secondary outcome of physical function (effect size = 0.53, p = .004). CONCLUSION. Occupational therapy intervention that includes aerobic and strengthening exercises may help improve independence in ADLs and improve physical performance in people with AD. Additional research is needed to identify specific components of intervention and optimal dosage to develop clinical guidelines.

Objectives Efforts to prevent activity of daily living (ADL) dependency may be improved through models that assess older adults’ dependency risk. We evaluated whether cognition and gait speed measures improve the predictive validity of interview-based models. Method Participants were 8,095 self-respondents in the 2006 Health and Retirement Survey who were aged 65 years or over and independent in five ADLs. Incident ADL dependency was determined from the 2008 interview. Models were developed using random 2/3rd cohorts and validated in the remaining 1/3rd. Results Compared to a c-statistic of 0.79 in the best interview model, the model including cognitive measures had c-statistics of 0.82 and 0.80 while the best fitting gait speed model had c-statistics of 0.83 and 0.79 in the development and validation cohorts, respectively. Conclusion Two relatively brief models, one that requires an in-person assessment and one that does not, had excellent validity for predicting incident ADL dependency but did not significantly improve the predictive validity of the best fitting interview-based models.

The purpose of this study was to analyze the impact of a standard, custom-made pressure glove vs The NewYork-Presbyterian Dexterity Glove (NYPDG) with silon application on the palmer surface on functional hand use of burn survivors. A standard, custom-made pressure glove and NYPDG were given to 18 participants in a randomized order. Subjects wore each glove for 7 to 10 days during all activities of daily living (ADL). Variables such as hand function, difficulty of fine and gross motor ADL, and participant glove preference were assessed with each glove condition. Data collection of the second glove took place 7 to 10 days later incorporating a quasiexperimental, repeated measure design. A crossover design was used to analyze the data. The NYPDG demonstrated significantly better results in all of the four outcome categories measured: time to complete the Jebsen, the Jebsen Likert scale, fine motor ADL, and gross motor ADL. This study demonstrated that functional tasks took less time to complete and were more easily performed when using the NYPDG.

People with Alzheimer's disease (AD) experience, in addition to the progressive loss of cognitive functions, a decline in functional performance such as mobility impairment and disability in activities of daily living (ADL). Functional decline in dementia is mainly linked to the progressive brain pathology. Peripheral biomechanical changes by advanced glycation end-products (AGEs) have been suggested but have yet to be thoroughly studied. A multi-center, longitudinal, one-year follow-up cohort study was conducted in 144 people with early stage AD or mixed Alzheimer's/Vascular dementia. Linear mixed model analyses was used to study associations between AGE-levels (AGE reader) and mobility (Timed Up and Go), and ADL (Groningen Activity Restriction Scale and Barthel index), respectively. A significant association between AGE levels and mobility (β = 3.57, 95%CI: 1.43-5.73) was revealed; however, no significant association between AGE levels and ADL was found. Over a one-year time span, mean AGE levels significantly increased, and mobility and ADL performance decreased. Change in AGE levels was not significantly correlated with change in mobility. This study indicates that high AGE levels could be a contributing factor to impaired mobility but lacks evidence for an association with ADL decline in people with early stage AD or mixed dementia. Future research is necessary on the reduction of functional decline in dementia regarding the effectiveness of interventions such as physical activity programs and dietary advice possibly in combination with pharmacologic strategies targeting AGE accumulation.

Older patients with lung cancer are a heterogeneous population making treatment decisions complex. This study aims to evaluate the value of geriatric assessment (GA) as well as the evolution of functional status (FS) in older patients with lung cancer, and to identify predictors associated with functional decline and overall survival (OS). At baseline, GA was performed in patients ≥70 years with newly diagnosed lung cancer. FS measured by activities of daily living (ADL) and instrumental activities of daily living (IADL) was reassessed at follow-up to define functional decline and OS was collected. Predictors for functional decline and OS were determined. Two hundred and forty-five patients were included in this study. At baseline, GA deficiencies were present in all domains and ADL and IADL were impaired in 51 and 63% of patients, respectively. At follow-up, functional decline in ADL was observed in 23% and in IADL in 45% of patients. In multivariable analysis, radiotherapy was predictive for ADL decline. No other predictors for ADL or IADL decline were identified. Stage and baseline performance status were predictive for OS. Older patients with lung cancer present with multiple deficiencies covering all geriatric domains. During treatment, functional decline is observed in almost half of the patients. None of the specific domains of the GA were predictive for functional decline or survival, probably because of the high impact of the aggressiveness of this tumor type leading to a poor prognosis.

Studies have demonstrated changes in activities of daily living after an exercise intervention in people with dementia (PWD) living in nursing homes (NH). However, some discrepancies are shown during follow-up. Our objective was to measure activities of daily living (ADL) performance during a 6-month observational follow-up after a 6-month exercise or social activity intervention in PWD living in NH. After cluster randomisation, 91 PWD living in NH performed a 6-month structured exercise intervention (n = 44) or a social activity intervention (n = 47). After the intervention, 85 PWD were assessed for post-intervention follow-up. Instrumental and basic activities of daily living (IADL, ADL) were measured at 6-month observational follow-up after the intervention using the Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory for Severe Alzheimer's Disease (ADCS-ADL-sev) scale (scores ranging from 0 to 51, higher is better). Compared to participants in the social activity, those who participated to the exercise intervention had a significant decrease of their ADCS-ADL-sev score (between-group adjusted mean difference: 4.6 points, p = 0.001) with IADL having the most decrease (2.8 points, p = 0.004). Unexpectedly, exercisers declined sharply in the performance of ADLs and IADLs, whereas participants in the social intervention group maintained their levels. The potential mechanisms to explain these findings remain still to be elucidated.

This study aimed to examine hand disorders, symptoms, overall hand function, activities of daily living (ADLs), and life satisfaction in elderly men with type 2 diabetes mellitus (DM), impaired glucose tolerance (IGT), and normal glucose tolerance (NGT). Subjects were interviewed and evaluated with a battery of clinical and laboratory tests, including hand assessment, and a questionnaire. HbA1c differed between groups (highest in DM, especially in long-term DM). Limited joint motion (LJM), for example, prayer sign and Dupuytren's contracture, was most common in individuals with DM, followed by individuals with IGT, as compared to those with NGT. Vibrotactile sense was impaired symmetrically in the index and little fingers in DM. However, there were no differences for sensibility, dexterity, grip strength, and cold intolerance between groups. Individuals with long-term (>15 years) DM were more affected regarding sensibility and ADL than individuals with short-term DM, who had more sleep disturbances. ADL difficulties were less among IGT subjects. Vibrotactile sense showed correlations with Semmes-Weinstein monofilament test and static two-point discrimination. Dupuytren's contracture and impaired vibrotactile sense in finger pulps occurred in patients with DM but not in those with IGT, although LJM occurred in both IGT and DM patients. A longer duration of DM was associated with more severe neuropathy and ADL difficulties. Life satisfaction was high, and hand disorders did not have a significant impact on ADL.

Chronic pain affects nursing home residents' daily life. Pain assessment is central to adequate pain management. The overall aim was to investigate effects of a pain management intervention on nursing homes residents and to describe staffs' experiences of the intervention. A cluster-randomized trial and a mixed-methods approach. Randomized nursing home assignment to intervention or comparison group. The intervention group after theoretical and practical training sessions, performed systematic pain assessments using predominately observational scales with external and internal facilitators supporting the implementation. No measures were taken in the comparison group; pain management continued as before, but after the study corresponding training was provided. Resident data were collected baseline and at two follow-ups using validated scales and record reviews. Nurse group interviews were carried out twice. Primary outcome measures were wellbeing and proxy-measured pain. Secondary outcome measures were ADL-dependency and pain documentation. Using both non-parametric statistics on residential level and generalized estimating equation (GEE) models to take clustering effects into account, the results revealed non-significant interaction effects for the primary outcome measures, while for ADL-dependency using Katz-ADL there was a significant interaction effect. Comparison group (n = 66 residents) Katz-ADL values showed increased dependency over time, while the intervention group demonstrated no significant change over time (n = 98). In the intervention group, 13/44 residents showed decreased pain scores over the period, 14/44 had no pain score changes ≥ 30% in either direction measured with Doloplus-2. Furthermore, 17/44 residents showed increased pain scores ≥ 30% over time, indicating pain/risk for pain; 8 identified at the first assessment and 9 were new, i.e. developed pain over time. No significant changes in the use of drugs was found in any of the groups. Nursing pain related documentation was sparse. In general, nurses from the outset were positive regarding pain assessments. Persisting positive attitudes seemed strengthened by continued assessment experiences and perceptions of improved pain management. The implementation of a systematic work approach to pain issues in nursing homes indicates that an increased awareness, collaboration across and shared understanding among the team members of the pain assessment results can improve pain management and lead to decreased physical deterioration or the maintenance of physical and functional abilities among NH residents. However, pain (proxy-measured) and wellbeing level did not reveal any interaction effects between the groups over time. The study was registered in ISRCTN71142240 in September 2012, retrospectively registered.

The aim of this study was to assess the Activities of Daily Living (ADL) in patients with Hunter syndrome (mucopolysaccharidosis II; MPS II) using a newly designed ADL questionnaire. We applied the questionnaire to evaluate clinical phenotypes and therapeutic efficacies of enzyme replacement therapy (ERT) and hematopoietic stem cell transplantation (HSCT). We also explored early signs and symptoms to make early diagnosis feasible. We devised a new ADL questionnaire with three domains: “Movement,” “Movement with Cognition,” and “Cognition.” Each domain has four subcategories rated on a 5-point scale based on level of assistance. We also scored signs and symptoms unique to MPS by 12 subcategories (five points per category), providing 60 points in total. The questionnaire was first administered to 138 healthy Japanese controls (0.33 – 50 years), and successively, to 74 Japanese patients with Hunter syndrome (4 – 49 years). The patient cohort consisted of 51 severe and 23 attenuated phenotypes; 20 patients treated with HSCT, 23 patients treated early with ERT (≤ 8 years), and 25 patients treated late with ERT (> 8 years), and 4 untreated patients. Among 18 severe phenotypic patients treated by HSCT, 10 were designated as early HSCT (≤ 5 years), while 8 were designated as late HSCT (> 5 years). Scores from patients with severe phenotypes were lower than controls and attenuated phenotypes in all categories. Among patients with severe phenotypes, there was a trend that HSCT provides a higher ADL score than early ERT, and there was a significant difference in ADL scores between late ERT and HSCT groups. Early ERT and early HSCT provided a higher score than late ERT and late HSCT, respectively. In conclusion, we have evaluated the feasibility of a new questionnaire in control population and patients with Hunter syndrome, leading to a novel evaluation method for clinical phenotypes and therapeutic efficacy. Early treatment with HSCT provides a better consequence in ADL of patients. PMID:25468646

To examine the association between cardiac function and activities of daily living (ADLs) in an age-homogenous, community-dwelling population born in 1920 and 1921. Cross-sectional analysis of a prospective cohort study. Community-dwelling elderly population. Participants were recruited from the Jerusalem Longitudinal Cohort Study, which has followed an age-homogenous cohort of Jerusalem residents born in 1920 and 1921. Four hundred eighty-nine of the participants (228 male, 261 female) from the most recent set of data collection in 2005 and 2006 underwent echocardiography at their place of residence in addition to structured interviews and physical examination. A home-based comprehensive assessment was performed to assess health and functional status, including performance of ADLs. Dependence was defined as needing assistance with one or more basic ADLs. Standard echocardiographic assessment of cardiac structure and function, including ejection fraction (EF) and diastolic function as assessed using early diastolic mitral annular tissue velocity measurements obtained using tissue Doppler, was performed. Of the participants with limitation in at least one ADL, significantly more had low EF (< 55%) than the group that was independent (52.6 % vs 39.1%; P=.01). In addition, participants with dependence in ADL had higher left ventricular mass index (LVMI) (129.3 vs 119.7 g/m²) and left atrial volume index (LAVI) (41.3 vs 36.7 mL/m²). There were no differences between the groups in percentage of participants with impaired diastolic function or average ratio of early diastolic transmitral flow velocity to early diastolic mitral annular tissue velocity (11.5 vs 11.8; P=.64). In this age-homogenous cohort of the oldest old, high LVMI and LAVI and indices of systolic but not diastolic function as assessed according to Doppler were associated with limitations in ADLs. © 2011, Copyright the Authors.

Seed coat phenolic compounds represent important antinutritive fibre components that cause a considerable reduction in value of seed meals from oilseed rape (Brassica napus). The nutritionally most important fibre compound is acid detergent lignin (ADL), to which a significant contribution is made by phenylpropanoid-derived lignin precursors. In this study, we used bulked-segregant analysis in a population of recombinant inbred lines (RILs) from a cross of the Chinese oilseed rape lines GH06 (yellow seed, low ADL) and P174 (black seed, high ADL) to identify markers with tight linkage to a major quantitative trait locus (QTL) for seed ADL content. Fine mapping of the QTL was performed in a backcross population comprising 872 BC(1)F(2) plants from a cross of an F(7) RIL from the above-mentioned population, which was heterozygous for this major QTL and P174. A 3:1 phenotypic segregation for seed ADL content indicated that a single, dominant, major locus causes a substantial reduction in ADL. This locus was successively narrowed to 0.75 cM using in silico markers derived from a homologous Brassica rapa sequence contig spanning the QTL. Subsequently, we located a B. rapa orthologue of the key lignin biosynthesis gene CINNAMOYL CO-A REDUCTASE 1 (CCR1) only 600 kbp (0.75 cM) upstream of the nearest linked marker. Sequencing of PCR amplicons, covering the full-length coding sequences of Bna.CCR1 homologues, revealed a locus in P174 whose sequence corresponds to the Brassica oleracea wild-type allele from chromosome C8. In GH06, however, this allele is replaced by a homologue derived from chromosome A9 that contains a loss-of-function frameshift mutation in exon 1. Genetic and physical map data infer that this loss-of-function allele has replaced a functional Bna.CCR1 locus on chromosome C8 in GH06 by homoeologous non-reciprocal translocation.

There are limited reports that compare muscle strength, functional exercise capacity, activities of daily living (ADL) and parameters of physical fitness of cystic fibrosis (CF) patients with healthy peers in the literature. The purpose of this study was to assess and compare respiratory and peripheral muscle strength, functional exercise capacity, ADL and physical fitness in patients with CF and healthy subjects. Nineteen patients with CF (mean forced expiratory volume in one second-FEV1: 86.56±18.36%) and 20 healthy subjects were included in this study. Respiratory (maximal inspiratory pressure-MIP and maximal expiratory pressure-MEP) and peripheral muscle strength (quadriceps, shoulder abductors and hand grip strength) were evaluated. Functional exercise capacity was determined with 6min walk test (6MWT). ADL was assessed with Glittre ADL test and physical fitness was assessed with Munich fitness test (MFT). There were not any statistically significant difference in MIP, %MIP, MEP and %MEP values between two groups (p>0.05). %Peripheral muscle strength (% quadriceps and shoulder abductors strength), 6MWT distance and %6MWT distance were significantly lower in patients with CF than those of healthy subjects (p<0.05). Glittre ADL-test time was significantly longer in patients with CF than healthy subjects (p<0.05). According to Munich fitness test, the number of bouncing a ball, hanging score, distance of standing vertical jumping and standing vertical jumping score were significantly lower in patients with CF than those of healthy subjects (p<0.05). Peripheral muscle strength, functional exercise capacity, ADL performance and speed, coordination, endurance and power components of physical fitness are adversely affected in mild-severe patients with CF compared to healthy peers. Evaluations must be done in comprehensive manner in patients with CF with all stages. Copyright © 2015 Elsevier Ltd. All rights reserved.

Fetal mice require light exposure in utero during early gestation for normal vascular development in the eye. Because angiogenic abnormalities in retinopathy of prematurity (ROP) are manifested in preterm infants, we investigated whether day length during early gestation was associated with severe ROP (SROP). Single-center, retrospective cohort study. We included a total of 343 premature infants (401-1250 g birth weight [BW], from 1998-2002): 684 eyes (1 eye each of 2 patients excluded) with 76 eyes developing SROP, defined as (1) classic threshold ROP in zone I or II, (2) type 1 ROP in zone I, or (3) in a few eyes, type 1 ROP in posterior zone II that was treated. For each infant, average day length (ADL) was calculated during different cumulative time periods and time windows after the estimated date of conception (EDC). Multiple logistic regression analysis (with generalized estimating equations to account for inter-eye correlation) was performed. Association of ADL during early gestation with SROP. In a model evaluating all 684 eyes with 76 eyes developing SROP, BW, gestational age, multiple births, race, per capita income in the mother's residence ZIP code, and ADL during the first 90 days after the EDC were factors associated with the development of SROP. Each additional hour of ADL (90 days) decreased the likelihood of SROP by 28% (P = 0.015; odds ratio [OR], 0.72; 95% confidence interval [CI], 0.55-0.94). In a model evaluating the subset of 146 prethreshold ROP eyes with 76 eyes developing SROP, each additional hour of ADL during the first 105 days after the EDC decreased the likelihood of SROP by 46% (P = 0.001; OR, 0.54; 95% CI, 0.37-0.78). Time windows when ADL was most closely associated with SROP were 31 to 60 days and 61 to 90 days after the EDC for the all eyes and the prethreshold ROP eyes models, respectively. Higher ADL during early gestation was associated with a lower risk for SROP and may imply a role for prophylactic light treatment during early gestation to decrease the risk of SROP.

Prospective clinical study. The purpose of this investigation was to quantify normal cervical range of motion (ROM) and compare these results to those used to perform 15 simulated activities of daily living (ADLs) in asymptomatic subjects. Previous studies looking at cervical ROM during ADLs have been limited and used measuring devices that do not record continuous motion. The purpose of this investigation was to quantify normal cervical ROM and compare these results with those used to perform 15 simulated ADLs in asymptomatic subjects. A noninvasive electrogoniometer and torsiometer were used to measure the ROM of the cervical spine. The accuracy and reliability of the devices were confirmed by comparing the ROM values acquired from dynamic flexion/extension and lateral bending radiographs to those provided by the device, which was activated while the radiographs were obtained. Intraobserver reliability was established by calculating the intraclass correlation coefficient for repeated measurements on the same subjects by 1 investigator on consecutive days. These tools were employed in a clinical laboratory setting to evaluate the full active ROM of the cervical spines (ie, flexion/extension, lateral bending, and axial rotation) of 60 asymptomatic subjects (30 females and 30 males; age, 20 to 75 y) as well as to assess the functional ROM required to complete 15 simulated ADLs. When compared with radiographic measurements, the electrogoniometer was found to be accurate within 2.3+/-2.2 degrees (mean+/-SD) and the intraobserver reliabilities for measuring the full active and functional ROM were both excellent (intraclass correlation coefficient of 0.96 and 0.92, respectively). The absolute ROM and percentage of full active cervical spinal ROM used during the 15 ADLs was 13 to 32 degrees and 15% to 32% (median, 20 degrees/19%) for flexion/extension, 9 to 21 degrees and 11% to 27% (14 degrees/18%) for lateral bending, and 13 to 57 degrees and 12% to 92% (18 degrees/19%) for rotation. Backing up a car required the most ROM of all the ADLs, involving 32% of sagittal, 26% of lateral, and 92% of rotational motion. In general, personal hygiene ADLs such as washing hands and hair, shaving, and applying make-up entailed a significantly greater ROM relative to locomotive ADLs including walking and traveling up and down a set of stairs (P<0.0001); in addition, compared with climbing up these steps, significantly more sagittal and rotational motion was used when descending stairs (P=0.003 and P=0.016, respectively). When picking up an object from the ground, a squatting technique required a lower percentage of lateral and rotational ROM than bending at the waist (P=0.002 and P<0.0001). By quantifying the amounts of cervical motion required to execute a series of simulated ADLs, this study indicates that most individuals use a relatively small percentage of their full active ROM when performing such activities. These findings provide baseline data which may allow clinicians to accurately assess preoperative impairment and postsurgical outcomes.

OBJECTIVES To examine differences in functional status among two successive cohorts. METHODS The study was a comparative analysis of Jewish respondents aged 75–94 from two nationwide random samples: the Cross-Sectional and Longitudinal Aging Study (1989–1992; N =1200) and the Survey of Health, Ageing, and Retirement in Europe (2005–2006; N =379). Self-reported functional limitation and disability were compared by means of logistic regressions and MANCOVA, controlling for age, gender, origin, education, marital status, income, self-rated health, and home care receipt. RESULTS Reported functional limitation decreased in the later cohort (SHARE-Israel), but ADL- and IADL-disability increased. Receipt of home care moderated these effects. ADL- and IADL-disability increased among home-care-receiving respondents in the later cohort whereas functional limitation decreased among respondents not in receipt of home care. DISCUSSION The findings suggest that different measures used to assess the disablement process capture different aspects, and that contextual factors influence how older people rate their own functional capacity.

This case report describes a unique long-term functional recovery process to promote successful community reintegration for a woman with Guillain-Barré syndrome (GBS), a rare autoimmune disease. Her main symptoms were very limited mobility and depressive symptoms due to the unknown cause of and cure for the illness. Holistic occupational strategies helped the client stabilize her emotional state, create a safe home environment, improve a communication method, increase physical activity, and promote social participation. Participation in a fall prevention clinical trial lowered her risk of falling; at 9 mo, she reached 75% of the maximum Social Integration score; at 13 mo, she reached near-normal level for activities of daily living (ADLs) and her fastest time for the Timed Up and Go test; and at 2 yr, she achieved a 100% score in instrumental ADLs. For community integration of clients with GBS, a comprehensive strategic self-management approach should be prescribed for long-term recovery.

Objective To assess the influence of cognitive, functional and behavioral factors, co-morbidities as well as caregiver characteristics on driving cessation in dementia patients. Methods The study cohort consists of those 240 dementia cases of the ongoing prospective registry on dementia in Austria (PRODEM) who were former or current car-drivers (mean age 74.2 (±8.8) years, 39.6% females, 80.8% Alzheimer’s disease). Reasons for driving cessation were assessed with the patients’ caregivers. Standardized questionnaires were used to evaluate patient- and caregiver characteristics. Cognitive functioning was determined by Mini-Mental State Examination (MMSE), the CERAD neuropsychological test battery and Clinical Dementia Rating (CDR), activities of daily living (ADL) by the Disability Assessment for Dementia, behavior by the Neuropsychiatric Inventory (NPI) and caregiver burden by the Zarit burden scale. Results Among subjects who had ceased driving, 136 (93.8%) did so because of “Unacceptable risk” according to caregiver’s judgment. Car accidents and revocation of the driving license were responsible in 8 (5.5%) and 1(0.7%) participant, respectively. Female gender (OR 5.057; 95%CI 1.803–14.180; p = 0.002), constructional abilities (OR 0.611; 95%CI 0.445–0.839; p = 0.002) and impairment in Activities of Daily Living (OR 0.941; 95%CI 0.911–0.973; p<0.001) were the only significant and independent associates of driving cessation. In multivariate analysis none of the currently proposed screening tools for assessment of fitness to drive in elderly subjects including the MMSE and CDR were significantly associated with driving cessation. Conclusion The risk-estimate of caregivers, but not car accidents or revocation of the driving license determines if dementia patients cease driving. Female gender and increasing impairment in constructional abilities and ADL raise the probability for driving cessation. If any of these factors also relates to undesired traffic situations needs to be determined before recommendations for their inclusion into practice parameters for the assessment of driving abilities in the elderly can be derived from our data.

Plantar fasciitis (PF) is a soft tissue disorder considered to be one of the most common causes of inferior heel pain. The aim of this study was to investigate the effect of monophasic pulsed current (MPC) and MPC coupled with plantar fascia-specific stretching exercises (SE) on the treatment of PF. Forty-four participants (22 women and 22 men, with a mean age of 49 years) diagnosed with PF were randomly assigned to receive MPC (n=22) or MPC coupled with plantar fascia-specific SE (n=22). Prior to and after 4 weeks of treatment, participants underwent baseline evaluation; heel pain was evaluated using a visual analogue scale (VAS), heel tenderness threshold was quantified using a handheld pressure algometer (PA), and functional activities level was assessed using the Activities of Daily Living subscale of the Foot and Ankle Ability Measure (ADL/FAAM). Heel pain scores showed a significant reduction in both groups compared to baseline VAS scores (P<0.001). Heel tenderness improved significantly in both groups compared with baseline PA scores (P<0.001). Functional activity level improved significantly in both groups compared with baseline (ADL/FAAM) scores (P<0.001). However, no significant differences existed between the 2 treatment groups in all post-intervention outcome measures. This trial showed that MPC is useful in treating inferior heel symptoms caused by PF.

high levels of social support and engagement may help sustain good health and functional ability. However, the definition of social support in previous research has been inconsistent and findings are mixed. The aim of this analysis was to explore the effect of two aspects of social support on subsequent disability in a group of community dwelling older women and men. data were drawn from two concurrent prospective observational cohort studies of community-based older Australian women (N = 2,013) and men (N = 680). Baseline and follow-up data were drawn from the second (1999) and fifth (2008) surveys of the women and the second (2001) and third (2008) surveys of the men. At baseline, social support was measured by the two subscales (social network and subjective support) of the Duke Social Support Index (DSSI). The outcome measure was Activities of Daily Living (ADLs) and Instrumental Activities of Daily Living (IADLs). overall, social network size was not associated with subsequent disability in either women or men. After adjusting for health status at baseline, lack of satisfaction with social support was associated with greater difficulties in ADLs and IADLs for both women and men. our results suggest that the provision of social support is insufficient to limit subsequent disability: support provided must be subjectively perceived to be relevant and adequate.

Religious social networks are well known for their capacity to improve individual health, yet the effects of friendship networks within the Buddhist context remain largely unknown. The present study aimed to compare health status and social support in community-dwelling older adults according to their level of Buddhist social network (BSN) involvement, and to examine the association between BSN involvement and functional health among older adults. A cross-sectional survey was carried out among 427 Buddhist community-dwelling older adults aged ≥60 years in Nakhon Pathom, Thailand. Data were collected from home-based personal interviews using a structured questionnaire. Health status was defined according to the measures of basic and advanced activities of daily living (ADL), the 15-item Geriatric Depression Scale and subjective quality of life. Perceived social support was assessed across the four dimensions of tangible, belonging, emotional and information support. Multiple logistic regression was used for analysis. Older adults with BSN involvement reported better functional, mental and social health status, and perceived greater social support than those without BSN involvement. In addition, BSN involvement was positively associated with independence in basic and advanced ADL. After adjusting for age, sex, education, income, morbidity and depressive symptoms, BSN showed a strong association with advanced ADL and a weak association with basic ADL. The results show that involvement in BSN could contribute positively to functional health, particularly with regard to advanced ADL. Addressing the need for involvement in these networks by older adults might help delay functional decline and save on healthcare costs. © 2014 Japan Geriatrics Society.

To analyze the hierarchical structure of activities of daily living (ADL) among vestibular older adults, according to its power to discriminate disability. An exploratory cross-sectional study was conducted comprising 235 elderly, aged 65 years and older, with chronic vestibular dysfunction. Functional capacity was assessed through the Brazilian version of OARS Multidimensional Functional Assessment Questionnaire which consists of 15 activities of daily living (ADL). The sample was classified in each ADL according to the difficulty level in performing the activity. A multiple correlation analysis technique and discriminant analysis was used to analyze the hierarchical structure of ADL. The sample consisted of 75.3% women, with an average age of 73.55±5.94 years. The ADL and their respective discrimination measurements were: getting into and out of bed (0.293); eating (0.129); combing hair (0.150); walking on flat surfaces (0.270); having a bath/shower (0.512); getting dressed (0.325); getting to the toilet in time (0.107); climbing stairs (0.338); taking medicines on time (0.035); walking close to home (0.529); shopping (0.503); preparing meals (0.398); cutting toenails (0.242); getting off buses (0.452); and cleaning the house (0.408). The tasks that reflect a higher demand upon the vestibular system were the most impaired, in the following order: walking close to home, having a bath/shower, shopping, getting off buses, cleaning the house, preparing meals, climbing stairs, getting dressed, getting into and out of bed, walking on flat surfaces, cutting toenails, combing hair, eating, getting to the toilet in time, taking medicines on time. © 2010 Japan Geriatrics Society.

Novel locomotor muscle design in extreme deep-diving whales.

Most marine mammals are hypothesized to routinely dive within their aerobic dive limit (ADL). Mammals that regularly perform deep, long-duration dives have locomotor muscles with elevated myoglobin concentrations that are composed of predominantly large, slow-twitch (Type I) fibers with low mitochondrial volume densities (V(mt)). These features contribute to extending ADL by increasing oxygen stores and decreasing metabolic rate. Recent tagging studies, however, have challenged the view that two groups of extreme deep-diving cetaceans dive within their ADLs. Beaked whales (including Ziphius cavirostris and Mesoplodon densirostris) routinely perform the deepest and longest average dives of any air-breathing vertebrate, and short-finned pilot whales (Globicephala macrorhynchus) perform high-speed sprints at depth. We investigated the locomotor muscle morphology and estimated total body oxygen stores of several species within these two groups of cetaceans to determine whether they (1) shared muscle design features with other deep divers and (2) performed dives within their calculated ADLs. Muscle of both cetaceans displayed high myoglobin concentrations and large fibers, as predicted, but novel fiber profiles for diving mammals. Beaked whales possessed a sprinter's fiber-type profile, composed of ~80% fast-twitch (Type II) fibers with low V(mt). Approximately one-third of the muscle fibers of short-finned pilot whales were slow-twitch, oxidative, glycolytic fibers, a rare fiber type for any mammal. The muscle morphology of beaked whales likely decreases the energetic cost of diving, while that of short-finned pilot whales supports high activity events. Calculated ADLs indicate that, at low metabolic rates, both beaked and short-finned pilot whales carry sufficient onboard oxygen to aerobically support their dives.

To study associations between disease and observed function and self-perceived health in very frail elders. Cross-sectional survey of nine nursing homes in San Antonio, TX. 194 elderly long-stay nursing home residents dependent in at least two ADLs and without severe cognitive impairment. Burden of disease (BOD) was chart abstracted using a standardized protocol that assessed types and severities of 59 categorizations of chronic and acute medical conditions. Observed function and self-perceived health status were assessed independently by the Katz Activities of Daily Living scale (ADL) and the Sickness Impact Profile (SIP), respectively. Summary BOD scores had a low, but statistically significant, univariate correlation with ADL scores (r = 0.21, P = 0.003) and no significant correlation with SIP scores (R = -0.008). Multiple linear regression analyses, including the 24 most frequent disease categories, showed that disease explained significant amounts of ADL (r2 = 0.25, P = 0.001) and borderline significant amounts of SIP (r2 = 0.16, P = 0.11). Models including both disease and sociodemographic, cognitive, and affective variables showed disease added significant incremental explantation beyond the other factors to ADL (incremental r2 = 0.14, P = 0.04), but not to SIP (incremental r2 = 0.08, P > 0.10). Disease, observed function, and self-perceived health status are separate, but interrelated entities, with disease having a stronger relationship to observed function than self-perceived health. Comprehensive assessment of frail elders may need to include all three areas, and studies that focus on one area should take into account the other two as potential important covariates.

Neoadjuvant chemoradiation (nCRT) followed by esophagectomy is a treatment with curative intent for resectable esophageal cancer. The aim of this study was to measure activities of daily living (ADL) and quality of life (QoL), and to examine correlates of changes in ADL and QoL. A prospective study was performed with three time points (baseline, 1 week after the end of nCRT, 3-months post-surgery) together with a cross-sectional post-treatment study. ADL was measured with the Amsterdam Linear Disability Score (ALDS), and QoL with the EORTC QLQ-C30 and the OES-18. Regression analysis was performed to identify factors associated with changes in ADL and QoL. Seventy-six patients were included in the prospective study, 79 in the cross-sectional study. After nCRT, ALDS decreased from 90 to 88 (P < 0.01) and remained stable after surgery. Global QoL decreased from 75 to 61 (P < 0.01); no significant changes were observed after surgery. Only timing of the measurement of ALDS was negatively associated with non-maximum ALDS (n = 155, based on both studies) and QoL (n = 76) (P < 0.01). Patients who undergo nCRT plus surgery should be prepared to experience a short-term decline in ADL and QoL. The findings of this study can support patients and healthcare workers to guide expectations. J. Surg. Oncol. 2016;114:684-690. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

The aim of this study was to describe asylum seekers' satisfaction with daily occupations and activity level while in a Danish asylum centre, and whether this changed over time. Another aim was to describe whether exposure to torture, self-rated health measures, and ADL ability were related to their satisfaction with daily occupations and activity level. A total of 43 asylum seekers at baseline and 17 at follow-up were included. The questionnaires Satisfaction with Daily Occupations, Major Depression Inventory, WHO-5 Wellbeing, Pain Detect, a questionnaire covering torture, and basic social information were used as well as Assessment of Motor and Process Skills. The results showed a low level of satisfaction with daily occupations at both baseline and follow-up. There was no statistically significant change in satisfaction or activity level between baseline and the follow-up. Associations between AMPS process skills--education, worst pain and activity level--were present at baseline, as was a relationship between AMPS process skills and satisfaction. At follow-up, associations between WHO-5 and satisfaction and activity level and between MDI scores and activity level were found. Asylum seekers experience a low level of satisfaction with daily occupations, both at arrival and after 10 months in an asylum centre. There is a need for further research and development of occupation-focused rehabilitation methods for the asylum seeker population.

Background Trajectories of disability are an essential component to understand the burden of disability at the societal level. Longitudinal studies, compared to cross-national studies, enable a better analysis of the progression of physical limitations among the elderly. However, information on disability dynamics in developing countries is limited. Objectives This paper examines the changes in activities of daily living (ADLs) in an 11-yr. period in the Mexican elderly population aged 60 or older and identifies how sociodemographic variables alter these trajectories. Methods The data come from the Mexican Health and Aging Study (MHAS), a national sample of adults born in 1951 or earlier, including a baseline survey in 2001 and follow-ups in 2003 and 2012. Results The ADL score increased on average by 0.03 for every year respondents aged after 60. In contrast, the ADL score was reduced by 0.06 for every additional year of education. Conclusions Age, gender, and years of education were confirmed to influence the trajectories of ADL limitations. Understanding the patterns of deterioration of functional limitations will help inform public health policies to better serve the population. PMID:26993585

Advanced battery technology evaluations are performed under simulated electric-vehicle operating conditions at the Analysis & Diagnostic Laboratory (ADL) of Argonne National Laboratory. The ADL results provide insight into those factors that limit battery performance and life. The ADL facilities include a test laboratory to conduct battery experimental evaluations under simulated application conditions and a post-test analysis laboratory to determine, in a protected atmosphere if needed, component compositional changes and failure mechanisms. This paper summarizes the performance characterizations and life evaluations conducted during FY-92 on both single cells and multi-cell modules that encompass six battery technologies (Na/S, Li/FeS, Ni/Metal-Hydride, Ni/Zn, Ni/Cd, Ni/Fe). These evaluations were performed for the Department of Energy, Office of Transportation Technologies, Electric and Hybrid Propulsion Division, and the Electric Power Research Institute. The ADL provides a common basis for battery performance characterization and life evaluations with unbiased application of tests and analyses. The results help identify the most promising R&D approaches for overcoming battery limitations, and provide battery users, developers, and program managers with a measure of the progress being made in battery R&D programs, a comparison of battery technologies, and basic data for modeling.

The purpose of this study was to identify the effects of hand acupuncture therapy on pain, ROM, ADL, and depression among older people with low back pain and knee joint pain. The research was a quasi-experimental design using a non-equivalent control group pre-post test. The participants were 40 patients, 18 in the experimental group and 22 in the control group. A pretest and 2 posttest were conducted to measure the main variables. For the experimental group, hand acupuncture therapy, consisting of hand acupuncture and press-pellets based on corresponding points, was given. There were statistically significant differences in pain, ROM in knee joint, and ADL in the experimental group but not in depression compared to the control group over two different times. The hand acupuncture therapy was effective for low back pain, knee joint pain, ROM in knee joint and ADL among the elders in this study. Therefore, the hand acupuncture therapy can be utilized in the field of geriatric nursing as a nursing intervention for older people with low back pain and knee joint pain.

To assess variation in gender gap (female-male) in inactive life expectancy (IALE) and active life expectancy (ALE) by definition of inactivity. Inactivity, among older Singaporeans, was defined as follows: Scenario 1-health-related difficulty in activities of daily living (ADLs); Scenario 2-health-related difficulty in ADLs/instrumental ADLs (IADLs); Scenario 3-health-related difficulty in ADLs/IADLs or non-health-related non-performance of IADLs. Multistate life tables computed IALE and ALE at age 60, testing three hypotheses: In all scenarios, life expectancy, absolute and relative IALE, and absolute ALE are higher for females (Hypothesis 1 [H1]); gender gap in absolute and relative IALE expands, and in absolute ALE, it contracts in Scenario 2 versus 1 (Hypothesis 2 [H2]); gender gap in absolute and relative IALE decreases, and in absolute ALE, it increases in Scenario 3 versus 2 (Hypothesis 3 [H3]). H1 was supported in Scenarios 1 and 3 but not Scenario 2. Both H2 and H3 were supported. Definition of inactivity influences gender gap in IALE and ALE. © The Author(s) 2016.

BACKGROUND: Next to health-related quality of life, information on daily life functioning in brain tumour patients is essential. Instrumental Activities of Daily Living (I-ADL) are complex daily activities, such as food preparation and shopping. I-ADL may be negatively influenced by a cognitive decline, characteristic of brain tumor patients. OBJECTIVE: In the first phase of this project, we generated a provisional list of items measuring I-ADL that are relevant for primary brain tumour patients. METHODS: Questions from the Amsterdam IADL Questionnaire®, a 70-item questionnaire developed and validated to measure I-ADL in patients with dementia, were evaluated for relevance to brain tumour patients. In addition, new activities were generated. In the first step, 6 professional experts in neuro-oncology and 10 primary brain tumour patient-proxy dyads were asked to evaluate items in the Amsterdam IADL Questionnaire®. Experts had to indicate if these activities (1) could be considered as I-ADL, (2) were affected in brain tumour patients and (3) were clearly formulated. Patients and their proxies only needed to answer the latter two questions. In the second step, the same 6 experts, and in addition 6 other patient-proxy dyads were asked to generate new activities. To do so, in-depth interviews were conducted. Decision rules were determined to aid in deciding which items to retain (step 1) or to add (step 2). Activities that were indicated as IADL, affected and clearly formulated were retained. Activities that were considered as IADL and affected, but not clearly formulated, were rephrased. New activities that were frequently generated were added to the existing list of items. RESULTS: In step 1, experts indicated that 37% of the activities described in the Amsterdam IADL questionnaire® fulfilled all three criteria: conform the definition of IADL, clearly formulated and affected in brain tumour patients. Twenty-three per cent of the activities were affected and conform the provided definition, but not clearly formulated. According to patients and their proxies, 19% and 17% of the activities were clearly formulated and affected in brain tumour patients, respectively. Moreover, 1-3% of the activities were indicated to be affected, but not clearly formulated. Several new activities (concerning social interaction and work) were generated in step 2. With the decision rules as guide, it was decided in consensus that a total of 30 questions of the Amsterdam IADL questionnaire® could also be used to measure I-ADL in primary brain tumour patients. In addition, 16 new questions covering other relevant activities for brain tumour patients were added. CONCLUSION: This first phase resulted in a provisional questionnaire of 46 items intending to measure I-ADL in primary brain tumour patients. The next step is to validate this provisional questionnaire in a larger sample of patients.

Minamata disease (MD), first discovered in 1956, is a neurological disorder caused by mercury poisoning due to daily intake of fish and shellfish that have been contaminated by methylmercury discharged from chemical factories. However, reports of ill health increased sharply following the 2004 Supreme Court ruling instructing the Japanese government to pay damages to MD patients. We examined the distribution of disability in activities of daily living (ADL), and the association between MD status in terms of compensation system and ADL disability among the general population of previously methylmercury-polluted areas. Data were collected by two-stage stratified sampling of residents 40-79 years old in 172 postal-code areas on the Shiranui Sea coast, the endemic area of MD. Questionnaires were distributed to eligible subjects (n = 2100) and collected at a later visit or by mail. Information on demographic factors, basic ADL (BADL), and instrumental ADL (IADL) was obtained using questionnaires. We performed logistic regression analysis to assess the relationship between MD status in terms of compensation system and ADL disability. We classified the 1422 residents who completed the questionnaire in accordance with their MD status in terms of compensation system: Early (those who received MD compensation before the Supreme Court decision), Recent (those who applied for compensation after the Supreme Court decision), Not Yet (those who have not yet applied for compensation, but have health-related anxieties about MD effects), and Normal (those who have not applied for compensation, and do not have health-related anxieties about MD effects). Adjusting for confounding factors, MD status was significantly associated with the disability grades of BADL and IADL with an increasing trend in the order of Normal, Not Yet, Recent, and Early. The odds ratios (95% CI) based on Normal were 2.08 (1.08-4.01), 3.87 (2.14-7.01), and 4.50 (2.66-7.61) for BADL and 2.41 (1.62-3.61), 3.20 (2.12-4.85) and 3.68 (2.52-5.38) in Not Yet, Recent, and Early for IADL, respectively. Early, Recent, and Not Yet had lower ADL grades than Normal. Moreover, the population with a low ADL grade and health-related anxieties had increased throughout the previously methylmercury-polluted areas. The issue of ill health among populations living in previously methylmercury-polluted areas should be addressed in the wider context of public and community health.

To determine whether the implementation of a national program to improve quality of care in geriatric rehabilitation (GR) in the Netherlands improves successful GR in terms of independence in activities of daily living (ADL), discharge destination, and length of stay. Prospective longitudinal study, comparing 2 consecutive cohorts: at the start of implementation (n = 386) and at 1 year after implementation (n = 357) of this program. Included were 16 skilled nursing facilities, 743 patients (median age 80 years, interquartile range 72-85; 64.5% females) indicated for GR and their health care professionals (elderly care physicians, physiotherapists, and nursing staff). National program to stimulate self-organizing capacity to develop integrated care to improve GR service delivery in 4 domains: alignment with patients' (care) needs, care coordination, team cooperation, and quality of care. Data on patients' characteristics, functional outcomes at admission and discharge, length of stay, and discharge destination were collected via an online questionnaire sent to health care professionals. The primary outcome measure was successful rehabilitation defined as independence in ADL (Barthel Index ≥15), discharge home, and a short length of stay (lowest 25% per diagnostic group). Generalized estimating equation analysis was used to adjust for age, gender, and clustering effects in the total population and for the 2 largest diagnostic subgroups, traumatic injuries and stroke. In the total population, at 1 year postimplementation there was 12% more ADL independence [odds ratio (OR) 1.59, 95% confidence interval (CI) 1.00-2.54]. Although successful rehabilitation (independence in ADL, discharge home, short length of stay) was similar in the 2 cohorts, patients with traumatic injuries were more successful 1 year postimplementation (OR 1.61, 95% CI 1.01-2.54). In stroke patients, successful rehabilitation was similar between the cohorts, but with more independence in ADL in the follow-up cohort (OR 1.99, 95% CI 1.09-3.63). This study shows that 1-year after the implementation of the Dutch national program to improve quality of care there was more independence in ADL at discharge, but the combined outcome of successful GR (independence in ADL, discharge home, short length of stay) was only significantly improved in patients with traumatic injuries.

The aim of the present study was to analyse the co-variation of different tests commonly used in stroke rehabilitation, and specifically used in a recent randomized, controlled study of two different physiotherapy models in stroke rehabilitation. Correlations of the performed tests and recordings from previous work were studied. The test results from three-month, one-year and four-year follow-up were analysed in an SPSS Version 11 statistical package with Pearson and Spearman correlations. There was an expected high correlation between the motor function tests, both based on partial and total scores. The correlations between Nottingham Health Profile Part 1 and Motor Assessment Scale (MAS), Sødring Motor Evaluation Scale (SMES), the Berg Balance Scale (BBS) and Barthel Activities of Daily Living (ADL) index were low for all items except physical condition. The correlations between registered living conditions, assistive devices, recurrent stroke, motor function (MAS, SMES), ADL (Barthel ADL index) and balance (BBS) were high. The same variables showed weak or poor correlation to the Nottingham Health Profile (NHP). The co-variations of motor function tests and functional tests were high, but the co-variations of motor, functional and self-reported life-quality tests were poor. The patients rated themselves on a higher functional level in the self-reported tests than was observed objectively in the performance-based tests. A possible reason for this is that the patients may have been unaware they modified their performance to adjust for physical decline, and consequently overestimate their physical condition. This result underlines the importance of both performance-based and self-reported tests as complementary tools in a rehabilitation process.

Evaluation of a complex intervention to improve activities of daily living of disabled cancer patients: protocol for a randomised controlled study and feasibility of recruitment and intervention

PubMed Central

2014-01-01

Background Many cancer patients have problems performing activities of daily living (ADL). A randomised controlled trial was designed to examine the effects of an ADL intervention in addition to standard treatment and care in a hospital setting. The objective of this article was to present the study and to analyse the feasibility of the recruitment process and the intervention. Methods Adult disabled cancer patients at Næstved Hospital in Denmark were enrolled between 1 March 2010 and 30 June 2011 and randomised into an ADL intervention or to a control group. The intervention was performed by occupational therapists. The feasibility of the recruitment was analysed with regard to success in achieving the estimated number of participants and identification of barriers, and feasibility of the intervention was based on calculations of patient attendance and patient acceptability. The primary outcome of the randomised controlled trial was patients’ health-related quality of life 2 and 8 weeks after baseline. Results A total of 118 disabled cancer patients were enrolled in the study over a time span of 16 months. Very few meetings between occupational therapist and patient were cancelled. Time spent on the intervention varied considerably, but for the majority of patients, time consumption was between 1–3 hours. Conclusions Despite difficulties with recruitment, participation was considered feasible and the intervention was accepted among patients. Missing data in the follow-up period were mostly due to death among participants. Very few participants declined to complete questionnaires during follow-up. PMID:24779438

Reference intervals are widely used as decision tools, providing the physician with information about whether the analyte values indicate ongoing disease process. Reference intervals are generally based on individuals without diagnosed diseases or use of medication, which often excludes elderly. The aim of the study was to assess levels of albumin, alanine aminotransferase (ALT), aspartate aminotransferase (AST), creatinine and γ-glutamyl transferase (γ-GT) in frail, moderately healthy and healthy elderly indivuduals. Blood samples were collected from individuals >80 years old, nursing home residents, in the Elderly in Linköping Screening Assessment and Nordic Reference Interval Project, a total of 569 individuals. They were divided into three cohorts: frail, moderately healthy and healthy, depending on cognitive and physical function. Albumin, ALT, AST, creatinine and γ-GT were analyzed using routine methods. Linear regression predicted factors for 34% of the variance in albumin were activities of daily living (ADL), gender, stroke and cancer. ADLs, gender and weight explained 15% of changes in ALT. For AST levels, ADLs, cancer and analgesics explained 5% of changes. Kidney disease, gender, Mini Mental State Examination (MMSE) and chronic obstructive pulmonary disease explained 25% of the variation in creatinine levels and MMSE explained three per cent of γ-GT variation. Because a group of people are at the same age, they should not be assessed the same way. To interpret results of laboratory tests in elderly is a complex task, where reference intervals are one part, but far from the only one, to take into consideration.

Methodological aspects of digestibility measurements were studied in four Welsh pony geldings consuming haylage-based diets with increasing proportions of a pelleted concentrate according to a 4×4 Latin square design experiment. Ponies were fed four experimental, iso-energetic (net energy (NE) basis) diets (i.e. 22 MJ NE/day) with increasing proportions of a pelleted concentrate (C) in relation to haylage (H). The absolute amounts of diet dry matter fed per day were 4.48 kg of H (100H), 3.36 and 0.73 kg of H and C (75H25C), 2.24 and 1.45 kg of H and C (50H50C) and 1.12 and 2.17 kg of H and C (25H75C). Diets were supplemented with minerals, vitamins and TiO2 (3.7 g Ti/day). Voluntary voided faeces were quantitatively collected daily during 10 consecutive days and analysed for moisture, ash, ADL, acid-insoluble ash (AIA) and Ti. A minimum faeces collection period of 6 consecutive days, along with a 14-day period to adapt the animals to the diets and become accustomed to the collection procedure, is recommended to obtain accurate estimations on dry matter digestibility and organic matter digestibility (OMD) in equids fed haylage-based diets supplemented with concentrate. In addition, the recovery of AIA, ADL and Ti was determined and evaluated. Mean faecal recovery over 10 consecutive days across diets for AIA, ADL and Ti was 124.9% (SEM 2.9), 108.7% (SEM 2.0) and 97.5% (SEM 0.9), respectively. Cumulative faecal recovery of AIA significantly differed between treatments, indicating that AIA is inadequate to estimate the OMD in equines. In addition, evaluation of the CV of mean cumulative faecal recoveries obtained by AIA, ADL and Ti showed greater variations in faecal excretion of AIA (9.1) and ADL (7.4) than Ti (3.7). The accuracy of prediction of OMD was higher with the use of Ti than ADL. The use of Ti is preferred as a marker in digestibility trials in equines fed haylage-based diets supplemented with increasing amounts of pelleted concentrate.

We aimed to describe the hierarchical structure of Instrumental Activities of Daily Living (IADL) and basic Activities of Daily Living (ADL) and trajectories of dependency before death in an elderly population using item response theory methodology. Data were obtained from a population-based French cohort study, the Personnes Agées QUID (PAQUID) Study, of persons aged ≥65 years at baseline in 1988 who were recruited from 75 randomly selected areas in Gironde and Dordogne. We evaluated IADL and ADL data collected at home every 2-3 years over a 24-year period (1988-2012) for 3,238 deceased participants (43.9% men). We used a longitudinal item response theory model to investigate the item sequence of 11 IADL and ADL combined into a single scale and functional trajectories adjusted for education, sex, and age at death. The findings confirmed the earliest losses in IADL (shopping, transporting, finances) at the partial limitation level, and then an overlapping of concomitant IADL and ADL, with bathing and dressing being the earliest ADL losses, and finally total losses for toileting, continence, eating, and transferring. Functional trajectories were sex-specific, with a benefit of high education that persisted until death in men but was only transient in women. An in-depth understanding of this sequence provides an early warning of functional decline for better adaptation of medical and social care in the elderly. © The Author 2016.

The aim of this study was to investigate healthcare utilization patterns over a six-year period among older people (60+), classified as dependent/independent in Activities of Daily Living (ADL) and/or at/not at risk of depression and to identify healthcare utilization predictors. A sample (n=1402) comprising ten age cohorts aged between 60 and 96 years was drawn from the Swedish National study on Aging and Care (SNAC). Baseline data were collected between 2001 and 2003. Number and length of hospital stays were collected for six years after baseline year. Group differences and mean changes over time were investigated. Healthcare utilization predictors were explored using multiple linear regression analysis. The results revealed that 21-24% had at least one hospital stay in the six years after baseline, 29-37% among ADL dependent subjects and 24-33% among those at risk of depression. There was a significant increase of hospital stays in all groups over time. ADL-dependent subjects and those at risk of depression had significant more hospital stays, except for those at/not at risk of depression in years 2, 4 and 5. The healthcare utilization predictors 5-6 years after baseline were mainly age, previous healthcare utilization and various symptoms and, in 1-2 and 3-4 years after baseline, age, various diagnostic groups and various physical variables. Thus healthcare utilization patterns seem to be similar for the different groups, but it is difficult to find universal predictors. This suggests that different variables should be considered, including both ADL and psychosocial variables, when trying to identify future healthcare users. Copyright © 2012 Elsevier Ireland Ltd.

To examine the association between function measured according to activities of daily living (ADLs), instrumental activ1ities of daily living (IADLs), and cognition assessed according to Mini-Mental State Examination (MMSE) scores of older African-American and non-Hispanic white community-dwelling men and women. Cross-sectional study assessing associations between self-reported ADL and IADL difficulty and MMSE scores for race- and sex-specific groups. Homes of community-dwelling older adults.

Function, based on self-reported difficulty in performing ADLs and IADLs, and cognition, using the MMSE. Multivariable linear regression models were used to test the association between function and cognition in race- and sex-specific groups after adjusting for covariates. Mini-Mental State Examination scores were modestly correlated with ADL and IADL difficulty in all four race- and sex-specific groups, with Pearson correlation coefficients ranging from −0.189 for non-Hispanic white women to −0.429 for African-American men. Correlations between MMSE and ADL or IADL difficulty in any of the race- and sex-specific groups were no longer significant after controlling for sociodemographic factors and comorbidities. Mini-Mental State Examination was not significantly associated with functional difficulty in older African-American and non-Hispanic white men and women after adjusting for sociodemographic factors and comorbidities, suggesting a mediating role in the relationship between cognition and function. © 2013, Copyright the Authors Journal compilation © 2013, The American Geriatrics Society.

Little is known about postdialysis fatigue (PDF), a debilitating symptom of hemodialysis patients. In 5 hemodialysis units of northern-centre Italy, patients were regarded to suffer from PDF if they spontaneously offered this complaint when asked the open-ended question: Do you feel better or worse after dialysis? If worse, please specify in which way. A complaint of fatigue would be probed further with questions directed at its duration, frequency and intensity, allowing creation of a fatigue index of severity (one third of the sum of these three parameters, each rated from 1 to 5). Patients were stratified into three groups according the severity of PDF: 1) score = 0; 2) score = 1-3; 3) score > 3. We studied 271 patients: 164 had PDF and 107 had not. PDF patients had significantly longer time of recovery after dialysis (TIRD). TIRD was significantly associated with PDF duration, intensity, and frequency. Patients with PDF were older and had a lower ADL score. At multivariate analysis, PDF was significantly associated with TIRD. In multivariate model that did not include TIRD, PDF was independently associated with age and ADL. Sixty patients had moderate PDF and 104 severe PDF. In patients with severe PDF, age and dialytic age were higher, ADL and IADL scores were lower, TIRD was longer and the ultrafiltration rate was lower. At multivariate analysis, PDF severity was independently associated with TIRD. In the model without TIRD, PDF severity was associated with ADL only. PDF is frequent and associated with age and ADL. Dialytic variables seem unrelated to PDF. This article is protected by copyright. All rights reserved.

To investigate pain, activities of daily living (ADL) function, sport function, quality of life and satisfaction at different time points after hip arthroscopy in patients with femoroacetabular impingement (FAI). Systematic review with meta-analysis. Weighted mean differences between preoperative and postoperative outcomes were calculated and used for meta-analysis. EMBASE, MEDLINE, SportsDiscus, CINAHL, Cochrane Library, and PEDro. Studies that evaluated hip pain, ADL function, sport function and quality of life before and after hip arthroscopy and postoperative satisfaction in patients with symptomatic FAI. Twenty-six studies (22 case series, 3 cohort studies, 1 randomised controlled trial (RCT)) were included in the systematic review and 19 in the meta-analysis. Clinically relevant pain and ADL function improvements were first reported between 3 and 6 months, and sport function improvements between 6 months and 1 year after surgery. It is not clear when quality of life improvements were first achieved. On average, residual mild pain and ADL and sport function scores lower than their healthy counterparts were reported by patients following surgery. Postoperative patient satisfaction ranged from 68% to 100%. On average, patients reported earlier pain and ADL function improvements, and slower sport function improvements after hip arthroscopy for FAI. However, average scores from patients indicate residual mild hip pain and/or hip function lower than their healthy counterparts after surgery. Owing to the current low level of evidence, future RCTs and cohort studies should investigate the effectiveness of hip arthroscopy in patients with FAI. CRD42015019649.

Arthritis and vitamin D insufficiency are prevalent in older adults and are risk factors for disability. The objective of this study was to examine the effect of co-occurring arthritis and vitamin D deficiency on upper-lower extremity functional limitations and disability in older adults. We examined 1533 participants aged ≥50 years from a subsample of the Mexican Health and Aging Study. Measures included sociodemographics, body mass index, comorbid conditions, falls, physical activity, physical function tests, functional limitations, activities of daily living (ADL), and vitamin D. Participants were categorized into four groups according to arthritis and vitamin D status: no vitamin D insufficiency and no arthritis (58.80%), vitamin D insufficiency only (27.49%), arthritis only (8.47%), and arthritis and vitamin D insufficiency (5.24%). Fourteen percent reported arthritis, and 31.2% had vitamin D insufficiency. The arthritis and vitamin D insufficiency group was associated with upper-lower extremity functional limitations [odds ratio (OR) 1.82, 95% confidence interval (CI) 1.06-3.15, and OR 1.90, 95% CI 1.00-3.62, respectively] and ADL disability (OR 3.00, 95% CI 1.63-5.51) when compared with the no vitamin D insufficiency and no arthritis group (reference group). The arthritis only group was three times more likely to report upper-lower extremity functional limitations and ADL disability. The vitamin D insufficiency only group was not significantly associated with functional limitations nor ADL disability. Arthritis and vitamin D insufficiency increased the risk of ADL disability in this population. However, the effect of arthritis and vitamin D insufficiency on upper-lower extremity functional limitations was not higher than the effect of arthritis only, but higher than the effect on vitamin D insufficiency alone.

To examine the neuropsychological and clinical profile of help-seekers in an early-detection community dementia program and to explore any relationship between profiles and time to seek help. Cross-sectional. Early-detection community dementia program. Help-seekers (N = 1,005) with subjective cognitive complaints or complaints from an informant. Neurocognitive testing, including the Cantonese Mini-Mental State Examination (MMSE), Clock Drawing Test, Digit Span, and Fuld Object Memory Evaluation and other clinical and functioning assessments, including the Clinical Dementia Rating (CDR), activities of daily living (ADLs), instrumental ADLs (IADLs), and depressive symptoms. Time since the person or an informant reported that they first noticed symptoms. Eighty-six percent of help-seekers had at least very mild dementia (CDR score ≥0.5). Cognitive performance was moderately impaired (mean MMSE score 18.4 ± 6.1). They required some assistance with IADLs, had very mild ADL impairments, and had few depressive symptoms. Median time to seek assessment was 12 months (interquartile range 7-30 months) according to the person or the informant (an adult child in 75% of the sample). Using the median-split method, time to seek assessment was classified as early (0-12 months) and late (>12 months). Worse cognitive and IADL performance but not ADL performance or depressive symptoms were observed in late than in early help-seekers. Longer time intervals between symptom recognition and early assessment showed a trend of further impairments on all measures except ADLs. A time interval of more than 12 months between symptom recognition and early assessment appears to be associated with worse cognitive function upon presentation. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

To assess the independent and combined impact of frailty, multi-morbidity, and activities of daily living (ADL) limitations on self-reported quality of life and healthcare costs in elderly people. Cross-sectional, descriptive study. Data came from The Older Persons and Informal Caregivers Minimum DataSet (TOPICS-MDS), a pooled dataset with information from 41 projects across the Netherlands from the Dutch national care for the Elderly programme. Frailty, multi-morbidity and ADL limitations, and the interactions between these domains, were used as predictors in regression analyses with quality of life and healthcare costs as outcome measures. Analyses were stratified by living situation (independent or care home). Directionality and magnitude of associations were assessed using linear mixed models. A total of 11,093 elderly people were interviewed. A substantial proportion of elderly people living independently reported frailty, multi-morbidity, and/or ADL limitations (56.4%, 88.3% and 41.4%, respectively), as did elderly people living in a care home (88.7%, 89.2% and 77,3%, respectively). One-third of elderly people living at home (31.9%) reported all three conditions compared with two-thirds of elderly people living in a care home (68.3%). In the multivariable analysis, frailty had a strong impact on outcomes independently of multi-morbidity and ADL limitations. Elderly people experiencing problems across all three domains reported the poorest quality-of-life scores and the highest healthcare costs, irrespective of their living situation. Frailty, multi-morbidity and ADL limitations are complementary measurements, which together provide a more holistic understanding of health status in elderly people. A multi-dimensional approach is important in mapping the complex relationships between these measurements on the one hand and the quality of life and healthcare costs on the other.

The purpose of this study was to analyze the nature of shared content of total joint arthroplasty patients on Instagram. Specifically, we evaluated social media posts for: (1) perspective and timing; (2) tone; (3) focus (activities of daily living [ADLs], rehabilitation, return-to-work); and (4) the comparison between hip and knee arthroplasties. A search of the public Instagram domain was performed over a 6-month period. Total hip and knee arthroplasties (THA and TKA) were selected for the analysis using the following terms: "#totalhipreplacement," "#totalkneereplacement," and associated terms. 1287 individual public posts of human subjects were shared during the period. A categorical scoring system was utilized for media format (photo or video), time (preoperative, perioperative, or postoperative) period, tone (positive or negative), return-to-work, ADLs, rehabilitation, surgical site, radiograph image, satisfaction, and dissatisfaction. Ninety-one percent of the posts were shared during the postoperative period. Ninety-three percent of posts had a positive tone. Thirty-four percent of posts focused on both ADLs and 33.8% on rehabilitation. TKA patients shared more about their surgical site (14.5% vs 3.3%, P < .001) and rehabilitation (58.9% vs 8.8%, P < .001) than THA patients, whereas THA patients shared more about ADLs than TKA patients (60.5% vs 7.6%, P < .001). When sharing their experience on Instagram, arthroplasty patients did so with a positive tone, starting a week after surgery. TKA posts focused more on rehabilitation and wound healing than THA patients, whereas THA patients shared more posts on ADLs. The analysis of social media posts provides insight into what matters to patients after total joint arthroplasty. Copyright © 2017 Elsevier Inc. All rights reserved.

Although measures of physical function are predictive of future disability, little is known about the short-term impact of changes in physical function on disability. Data from 93 of the 102 women who participated in the Weekly Substudy of the Women's Health and Aging Study (WHAS) were used to explore the association of changes in physical function with disability. The WHAS Substudy included 24 weekly assessments of three standard performance tests and self-reported disability in activities of daily living (ADLs) and basic mobility. Using random-effects models, we found small but significant (ps <.01) changes in ADL and mobility disability during weekly follow-up. Baseline performance scores were significantly associated with both ADL and mobility disability (ps <.001), accounting for 27% and 36% of the between-person variability in each type of disability, respectively. After adjustment for baseline scores, change in performance scores was significantly associated with ADL disability (beta = 0.08, p <.01) and mobility disability (beta = 0.12, p <.001), but accounted only for a small proportion (<10%) of the variability in the rate of change in disability outcomes. There was no evidence for an additional effect on either type of disability because of having a single episode of a higher or lower than usual performance score, or because of periods of at least 4 consecutive higher or lower than usual performance test scores. Basic physical functions account for a substantial proportion of the heterogeneity in ADL and mobility disability among older disabled women, but have a relatively small impact on short-term changes in either type of disability. Effective prevention of disability may require attention to a wider array of risk factors than just limitations in basic physical functions.

Activities of daily living, instrumental activities for daily living and predictors of functional capacity of older men in Jamaica

Bourne, Paul Andrew

2009-01-01

Background: An extensive search of the literature found no studies that have examined functional capacity [Activities of Daily Living (ADL) and Instrumental Activities for Daily Living (I) ADL)] of Jamaican older men as well as factors that determine their functional capacity. Aims: The current study examines 1) ADL, 2) (I) ADL), 3) self-reported health status, 4) functional capacity, and 5) factors that determine functional capacity of older men. Methods and Method: Stratified multistage probability sampling technique was used to draw a sample of 2,000 55+ year men. A132-item questionnaire was used to collect the data. Descriptive statistics provide background information on the sample, cross tabulations were used to examine non-metric variables and logistic regression provides a model of predictors of functional capacity. Result: Fifty-five percent of sample indicated good current health status. Four percent was mostly satisfied with life; 21.7% had moderate dependence; 77.1% had high dependence (i.e. independence); 1.2% had low dependence; 21.9% were ages 75 years and older; 35.6% were ages 65 to 74 years and 42.6% reported ages 55 to 64 years. Functional capacity can be determined by church attendance (β=0.245; 95% CI: 0.264, 1.291); social support (β=0.129; 95% CI: 0.129, 0.258), area of residence (β=-0.060; 95% CI: -0.427, -0.061) and lastly by age of respondents. Conclusion: Ageing in explains deterioration in their (I) ADL, suggesting the challenges of ageing men's independence. More rural men were rarely satisfied with life; but more of them had a greater functional capacity than urban men. Depression was found to negatively relate to functional capacity, and church attendees had a greater functional status than non-attendees. PMID:22666693

Knowledge on disability's impact among older women and men in Ecuador is limited. This paper provides gender-specific estimates of disability prevalence, life expectancy with and without disability, and the factors associated with gender differences in disability at older age in Ecuador (2009-2010). Data from the Health, Well-Being, and Aging Survey (SABE) Ecuador 2009 was used. Participants were 4480 men and women aged 60 and over. Life expectancy with and without disability was calculated using the Sullivan method. Logistic regression analyses were used to explore gender differences in disability prevalence. Two disability measures, indicating limitations in activities of daily living (ADL) and instrumental activities of daily living (IADL), were used. 60-year-old women in Ecuador can expect to live 16.3 years without ADL limitations compared to 16.9 years for men. Life expectancy without IADL limitations was 12.5 years for women and 15.5 years for men. At age 60, women's length of life with ADL and IADL disability was higher (7.9 years for women vs. 4.9 years for men with ADL, and 11.7 years for women vs. 6.3 years for men with IADL). After controlling for socioeconomic characteristics, chronic conditions and lifestyle factors, gender differences in ADL disability were not statistically significant. However, older women were 58% more likely (OR=1.58, 95% CI 1.27, 1.95) to report having IADL limitations than men, even after including control variables. Interventions should tackle chronic disease, physical inactivity, and socioeconomic differences to reduce women's vulnerability to disability in older age. Copyright © 2015 Elsevier Ireland Ltd.

Feeding state and food availability can dramatically alter an animals' sensory response to chemicals in its environment. Dynamic changes in the expression of chemoreceptor genes may underlie some of these food and state-dependent changes in chemosensory behavior, but the mechanisms underlying these expression changes are unknown. Here, we identified a KIN-29 (SIK)-dependent chemoreceptor, srh-234, in C. elegans whose expression in the ADL sensory neuron type is regulated by integration of sensory and internal feeding state signals. We show that in addition to KIN-29, signaling is mediated by the DAF-2 insulin-like receptor, OCR-2 TRPV channel, and NPR-1 neuropeptide receptor. Cell-specific rescue experiments suggest that DAF-2 and OCR-2 act in ADL, while NPR-1 acts in the RMG interneurons. NPR-1-mediated regulation of srh-234 is dependent on gap-junctions, implying that circuit inputs regulate the expression of chemoreceptor genes in sensory neurons. Using physical and genetic manipulation of ADL neurons, we show that sensory inputs from food presence and ADL neural output regulate srh-234 expression. While KIN-29 and DAF-2 act primarily via the MEF-2 (MEF2) and DAF-16 (FOXO) transcription factors to regulate srh-234 expression in ADL neurons, OCR-2 and NPR-1 likely act via a calcium-dependent but MEF-2- and DAF-16-independent pathway. Together, our results suggest that sensory- and circuit-mediated regulation of chemoreceptor genes via multiple pathways may allow animals to precisely regulate and fine-tune their chemosensory responses as a function of internal and external conditions.

Because the prevalence of many brain disorders rises with age, and brain disorders are costly, the economic burden of brain disorders will increase markedly during the next decades. The purpose of this study is to analyze how the costs to society vary with different levels of functioning and with the presence of a brain disorder. Resource utilization and costs from a societal viewpoint were analyzed versus cognition, activities of daily living (ADL), instrumental activities of daily living (IADL), brain disorder diagnosis and age in a population-based cohort of people aged 65 years and older in Nordanstig in Northern Sweden. Descriptive statistics, non-parametric bootstrapping and a generalized linear model (GLM) were used for the statistical analyses. Most people were zero users of care. Societal costs of dementia were by far the highest, ranging from SEK 262,000 (mild) to SEK 519,000 per year (severe dementia). In univariate analysis, all measures of functioning were significantly related to costs. When controlling for ADL and IADL in the multivariate GLM, cognition did not have a statistically significant effect on total cost. The presence of a brain disorder did not impact total cost when controlling for function. The greatest shift in costs was seen when comparing no dependency in ADL and dependency in one basic ADL function. It is the level of functioning, rather than the presence of a brain disorder diagnosis, which predicts costs. ADLs are better explanatory variables of costs than Mini mental state examination. Most people in a population-based cohort are zero users of care. Copyright © 2012 John Wiley & Sons, Ltd.

An explorative, cross-sectional study into abnormal muscular coupling during reach in chronic stroke patients

PubMed Central

2010-01-01

Background In many stroke patients arm function is limited, which can be related to an abnormal coupling between shoulder and elbow joints. The extent to which this can be translated to activities of daily life (ADL), in terms of muscle activation during ADL-like movements, is rather unknown. Therefore, the present study examined the occurrence of abnormal coupling on functional, ADL-like reaching movements of chronic stroke patients by comparison with healthy persons. Methods Upward multi-joint reaching movements (20 repetitions at a self-selected speed to resemble ADL) were compared in two conditions: once facilitated by arm weight compensation and once resisted to provoke a potential abnormal coupling. Changes in movement performance (joint angles) and muscle activation (amplitude of activity and co-activation) between conditions were compared between healthy persons and stroke patients using a repeated measures ANOVA. Results The present study showed slight changes in joint excursion and muscle activation of stroke patients due to shoulder elevation resistance during functional reach. Remarkably, in healthy persons similar changes were observed. Even the results of a sub-group of the more impaired stroke patients did not point to an abnormal coupling between shoulder elevation and elbow flexion during functional reach. Conclusions The present findings suggest that in mildly and moderately affected chronic stroke patients ADL-like arm movements are not substantially affected by abnormal synergistic coupling. In this case, it is implied that other major contributors to limitations in functional use of the arm should be identified and targeted individually in rehabilitation, to improve use of the arm in activities of daily living.

This study evaluated the cross-sectional and longitudinal associations of functional and health status with institutional care, and examined determinants of institutional care use over time. Data of this study were obtained from the Survey of Health and Living Status of the Elderly in Taiwan (SHLSET), which was launched in 1989 and involved a nationally representative sample of nearly-old and old Taiwanese. The baseline data in this present study were collected in 1999, and followed in 2003 and 2007. Participants with institutional care use had a higher activities of daily living (ADL) score, more self-reported diseases and poorer self-reported health status than participants without institutional care use (all P<0.05). Cross-sectional analysis showed that a higher ADL score, having heart diseases and having a stroke were positively associated with institutional care use (P<0.05); whereas the number of self-reported diseases and poor self-reported health status were not associated with institutional care use. Longitudinal analysis showed that increased ADL scores and the number of self-reported diseases over 4- and 8 years were associated with an increased likelihood of subsequent institutional care use (all P<0.05). Worsening health status over 4 years was associated with an increased likelihood of subsequent institutional care use, but this association did not exist over 8 years. Only ADL and ADL deterioration over time are cross-sectionally and longitudinally associated with increased institutional care use. Declining functional status is a major determinant of institutional care use for Taiwanese aged over 53 years. © 2012 Japan Geriatrics Society.

The Hip Outcome Score (HOS) is a self-reported questionnaire evaluating the outcomes of treatment interventions for hip pathologies, divided in 19 items of activities of daily life (ADL) and 9 sports' items. The aim of the present study is to translate and validate HOS into Spanish. A prospective and multicenter study with 100 patients undergoing hip arthroscopy was performed between June 2012 and January 2013. Crosscultural adaptation was used to translate HOS into Spanish. Patients completed the questionnaire before and after surgery. Feasibility, reliability, internal consistency, construct validity (correlation with Western Ontario and McMaster Universities Osteoarthritis Index), ceiling and floor effects and sensitivity to change were assessed for the present study. Mean age was 45.05 years old. 36 women and 64 men were included. Feasibility: 13% had at least one missing item within the ADL subscale and 17% within the sport subscale. Reliability: the translated version of HOS was highly reproducible with intraclass correlation coefficient of 0.95 for ADL and 0.94 for the sports subscale. Internal consistency was confirmed with Cronbach's alpha >0.90 in both subscales. Construct validity showed statistically significant correlation with WOMAC. Ceiling effect was observed in 6% and 12% for ADL and sports subscale, respectively. Floor effect was found in 3% and 37% ADL and sports subscale, respectively. Large sensitivity to change was shown in both subscales. The translated version of HOS into Spanish has shown to be feasible, reliable and sensible to changes for patients undergoing hip arthroscopy. This validated translation of HOS allows for comparisons between studies involving either Spanish- or English-speaking patients. Prognostic study, Level I.

Use of a novel tunable solid state disk laser as a diagnostic system for laser-induced fluorescence

NASA Astrophysics Data System (ADS)

Paa, Wolfgang; Triebel, Wolfgang

2004-09-01

An all solid state disk laser system-named "Advanced Disk Laser (ADL)" -particularly tailored for laser induced fluorescence (LIF) in combustion processes is presented. The system currently under development comprises an Yb:YAG-seedlaser and a regenerative amplifier. Both are based on the disk laser concept as a new laser architecture. This allows a tunable, compact, efficient diode pumped solid state laser (DPSSL) system with repetition rates in the kHz region. After frequency conversion to the UV-spectral region via third and fourth harmonics generation, this laser-due to its unique properties such as single-frequency operation, wavelength tuneability and excellent beam profile-is well suited for excitation of small molecules such as formaldehyde, OH, NO or O2, which are characteristic for combustion processes. Using the method of planar laser induced fluorescence (PLIF) we observed concentration distributions of formaldehyde in cool and hot flames of a specially designed diethyl-ether burner. The images recorded with 1 kHz repetition rate allow visualizing the distribution of formaldehyde on a 1 ms time scale. This demonstrates for the first time the usability of this novel laser for LIF measurements and is the first step towards integration of the ADL into capsules for drop towers and the international space station.

When bone tissue, which plays a central role in locomotive organs, is broken by trauma and decreased in its own function of support, it is lead to be remarkable decline in the activity of daily life (ADL). Recently, in a clinical situation, various treatments have been tried for prophylaxis of fractures, and these treatments have been rewarded with good results. However, fractures would be occurred in a certain amount and there would be serious problems in ADL if the treatment fails to repair fractures. Furthermore, fractures could spontaneously heal in several weeks, it can be achieved in early rehabilitation and improvement of ADL, if we can accelerate fracture healing. Bone morphogenetic proteins, which were advocated by Dr. Urist, would be expected to be a key to establish much better society especially for the old.

Towards a future robotic home environment: a survey.

Demographic change has resulted in an increase of elderly people, while at the same time the number of active working people is falling. In the future, there will be less caretaking, which is necessary to support the aging population. In order to enable the aged population to live in dignity, they should be able to perform activities of daily living (ADLs) as independently as possible. The aim of this paper is to describe several solutions and concepts that can support elderly people in their ADLs in a way that allows them to stay self-sufficient for as long as possible. To reach this goal, the Building Realization and Robotics Lab is researching in the field of ambient assisted living. The idea is to implement robots and sensors in the home environment so as to efficiently support the inhabitants in their ADLs and eventually increase their independence. Through embedding vital sensors into furniture and using ICT technologies, the health status of elderly people can be remotely evaluated by a physician or family members. By investigating ergonomic aspects specific to elderly people (e.g. via an age-simulation suit), it is possible to develop and test new concepts and novel applications, which will offer innovative solutions. Via the introduction of mechatronics and robotics, the home environment can be made able to seamlessly interact with the inhabitant through gestures, vocal commands, and visual recognition algorithms. Meanwhile, several solutions have been developed that address how to build a smart home environment in order to create an ambient assisted environment. This article describes how these concepts were developed. The approach for each concept, proposed in this article, was performed as follows: (1) research of needs, (2) creating definitions of requirements, (3) identification of necessary technology and processes, (4) building initial concepts, (5) experiments in a real environment, and (6) development of the final concepts. To keep these concepts cost-effective, the suggested solutions are modular. Therefore, it will be possible to straightforwardly install the proposed devices in an existing home environment in a 'plug and play' manner once the terminals can be prefabricated off-site. This article shows a variety of concepts that have been developed to support elderly people in their ADLs. The prototypes of the proposed concepts in this paper have been tested with elderly people. The results of the tests show that robots embedded in furniture, walls, ceiling, etc. offer enhanced support, properly addressing elderly as well as disabled people to individually and independently manage their ADLs. In order to make the concepts realizable in terms of cost, it will be necessary to standardize and modularize these concepts for industrial fabrication. © 2014 S. Karger AG, Basel

The objective of this study is to investigate the cross-cultural relationship between depressive state and subjective economic status, as well as subjective quality of life (QOL) and activities of daily living (ADL) among elderly people in communities in Japan, Taiwan, and Korea. We studied 595 subjects aged 65 years or older in three Asian communities (261 subjects in T town in Japan, 164 in D town in Taiwan, and 170 in H town in Korea). The Geriatric Depression Scale-15, a self-rating questionnaire assessing ADL, subjective QOL, social situations, and past and current medical status, was used. Depression of the elderly was associated with dependence in basic ADL, subjective QOL, and subjective sense of low economic status. After adjusting for the effects of age, sex, and basic ADL, subjective sense of low economic status was closely associated with depression in community-living elderly people in all three communities in Asia. In conclusion, absolute and objective economic status is an important contributing factor to depressive state or psychosocial deterioration, however, we should pay more attention to the roles of perception of low economic status in determining depressive state in community-dwelling elderly people.

Advanced battery technology evaluations are performed under simulated electric-vehicle operating conditions at the Analysis and Diagnostic Laboratory (ADL) of Argonne National Laboratory. The ADL results provide insight into those factors that limit battery performance and life. The ADL facilities include a test laboratory to conduct battery experimental evaluations under simulated application conditions and a post-test analysis laboratory to determine, in a protected atmosphere if needed, component compositional changes and failure mechanisms. This paper summarizes the performance characterizations and life evaluations conducted during 1991-1992 on both single cells and multi-cell modules that encompass eight battery technologies (Na/S, Li/MS (M=metal), Ni/MH, Ni/Cd, Ni/Zn, Ni/Fe, Zn/Br, and Pb-acid). These evaluations were performed for the Department of Energy, Office of Transportation Technologies, Electric and Hybrid Propulsion Division, and the Electric Power Research Institute. The ADL provides a common basis for battery performance characterization and life evaluations with unbiased application of tests and analyses. The results help identify the most-promising R&D approaches for overcoming battery limitations, and provide battery users, developers, and program managers with a measure of the progress being made in battery R&D programs, a comparison of battery technologies, and basic data for modeling.

Research on fall and movement detection with wearable devices has witnessed promising growth. However, there are few publicly available datasets, all recorded with smartphones, which are insufficient for testing new proposals due to their absence of objective population, lack of performed activities, and limited information. Here, we present a dataset of falls and activities of daily living (ADLs) acquired with a self-developed device composed of two types of accelerometer and one gyroscope. It consists of 19 ADLs and 15 fall types performed by 23 young adults, 15 ADL types performed by 14 healthy and independent participants over 62 years old, and data from one participant of 60 years old that performed all ADLs and falls. These activities were selected based on a survey and a literature analysis. We test the dataset with widely used feature extraction and a simple to implement threshold based classification, achieving up to 96% of accuracy in fall detection. An individual activity analysis demonstrates that most errors coincide in a few number of activities where new approaches could be focused. Finally, validation tests with elderly people significantly reduced the fall detection performance of the tested features. This validates findings of other authors and encourages developing new strategies with this new dataset as the benchmark. PMID:28117691

A systematic review with meta-analysis was performed to investigate the effect external sensory cued therapy on activities of daily living (ADL) performance that include walking and daily tasks such as dressing for individuals with Parkinson's disease (PD). A detailed computer-aided search of the literature was applied to MEDLINE, Cumulative Index to Nursing and Allied Health Literature, EMBASE and PubMed. Studies investigating the effects of external sensory cued therapy on ADL performance for individuals with PD in all stages of disease progression were collected. Relevant articles were critically reviewed and study results were synthesized by two independent researchers. A data-analysis method was used to extract data from selected articles. A meta-analysis was carried out for all randomized-controlled trials. Six studies with 243 individuals with PD were included in this review. All six studies yielded positive findings in favour of external sensory cues. The meta-analysis showed that external sensory cued therapy improved statistically after treatment (P=0.011) and at follow-up (P<0.001) for ADL performance. The results of this review provided evidence of an improvement in ADL performance in general in individuals with PD. It is recommended that clinicians incorporate external sensory into a training programme focused on improving daily task performance.

Significant Change Spotting for Periodic Human Motion Segmentation of Cleaning Tasks Using Wearable Sensors

Liu, Kai-Chun; Chan, Chia-Tai

2017-01-01

The proportion of the aging population is rapidly increasing around the world, which will cause stress on society and healthcare systems. In recent years, advances in technology have created new opportunities for automatic activities of daily living (ADL) monitoring to improve the quality of life and provide adequate medical service for the elderly. Such automatic ADL monitoring requires reliable ADL information on a fine-grained level, especially for the status of interaction between body gestures and the environment in the real-world. In this work, we propose a significant change spotting mechanism for periodic human motion segmentation during cleaning task performance. A novel approach is proposed based on the search for a significant change of gestures, which can manage critical technical issues in activity recognition, such as continuous data segmentation, individual variance, and category ambiguity. Three typical machine learning classification algorithms are utilized for the identification of the significant change candidate, including a Support Vector Machine (SVM), k-Nearest Neighbors (kNN), and Naive Bayesian (NB) algorithm. Overall, the proposed approach achieves 96.41% in the F1-score by using the SVM classifier. The results show that the proposed approach can fulfill the requirement of fine-grained human motion segmentation for automatic ADL monitoring. PMID:28106853

The prevalence and incidence of both obesity and disability are projected to increase in the coming decades. The authors examined the relation between obesity and disability in older adults from 6 Latin American cities participating in the Health, Well-Being and Aging in Latin America and the Caribbean (SABE) Study (1999-2000). The sample included 6,166 participants aged 65 years or more. Data on sociodemographic factors, smoking status, medical conditions, body mass index (BMI; weight (kg)/height (m)(2)), and self-reported activities of daily living (ADL) were obtained. The prevalence of obesity (BMI > or = 30) ranged from 13.3% in Havana, Cuba, to 37.6% in Montevideo, Uruguay. Using a BMI of 18.5-<25 as the reference category and controlling for all covariates, the lowest odds ratio for ADL limitation was for a BMI of 25-<30 (odds ratio = 1.10, 95% confidence interval: 0.93, 1.30), and the highest odds ratio for ADL limitation was for a BMI of 35 or higher (odds ratio = 1.63, 95% confidence interval: 1.26, 2.11). The results indicated that obesity is an independent factor contributing to ADL disability in these populations and should be included in future planning to reduce the impact of disability on global health.

To determine the relationship between impairments, disability and handicap in reflex sympathetic dystrophy (RSD) patients. A long-term follow-up study of upper extremity RSD patients. A university hospital. Sixty-five patients, 3-9 years (mean interval 5.5 years) after RSD of the upper extremity (mean age 50.2 years). Impairments: range of motion, moving two point discrimination, muscle strength of the hand and pain were measured. Disability was assessed with the Groningen Activity Restriction Scale (GARS) and handicap was assessed with three subscales (social functioning, role limitations due to physical problems and role limitations due to emotional problems) of the RAND-36. After RSD of the upper extremity, 62% of the patients are limited in activities of daily living (ADL) and/or instrumental ADL (IADL). Pain and restrictions in forward flexion of the shoulder, thumb opposition and grip strength are the most important impairments limiting ADL and IADL. Patients with limitations in ADL and IADL are significantly more handicapped than patients without limitations. Pain is the most important factor contributing to handicap. The relationship between impairments and disability and between disability and handicap in RSD patients is weak to moderate. Pain is the most important factor leading to disability and handicap.

Fibromyalgia is a chronic disease of unknown etiology characterized by widespread muscle pain, with occupational, familial, social, physical and psychological performance involvement. The multidisciplinary approach to the disease leads to improvement in quality of life and symptomatology. To evaluate the improvement of activities of daily living (ADL) and quality of life following a multidisciplinary intervention (Health Primary Care and Occupational Therapy). Pretest-posttest study performed with a simple random sample of 21 patients with fibromyalgia (range 16-55 years). The measurement was performed with the Barthel scale (ADL), the scale of Lawton and Brody (IADL), the FIQ questionnaire, and no standardized surveys to assess the pre and post intervention situation. An intervention on motor skills (basic motor skills, pool exercise, outdoor exercise, restructuring, occupational performance and graded activity and intervention in ADL) was performed, combining pharmacological control of their symptoms and treatment. Fibromyalgia patients are not fully satisfied with their treatment; Primary Care receives a score of 6.89, and Hospital Care 5.79, improving the Barthel, Lawton and Brody and FIQ indexes, being statistically significant (p<.05). After the combined procedure the number of independent women in ADL and IADL increases. Copyright © 2013 Elsevier España, S.L.U. All rights reserved.

1992-01-01

The study was carried out at W. hospital, an affiliated hospital of Y university, involved a total of 163 patients who were discharged from the hospital between May 1990 and March 1991. Data collection was twice, just prior to discharge and a minimum of three months post discharge. Thirty patients who lived within a hour travel time of the hospital received home care during the three months post discharge. Nursing diagnoses and nursing interventions for these patients were analyzed in this study. The results of the study are summarized as follows: 1. Discharge needs for the subjects of the study were analyzed using Gordon's eleven functional categories and it was found that 48.3% of the total sample had identified nursing needs. Of these, the needs most frequently identified were in the categories of sexuality, 79.3%, health perception, 68.2% self concept, 62.5%, and sleep and rest 62.5%. Looking at the nursing diagnosis that were made for the 30 patients receiving home care, the following diagnoses were the most frequently given; alteration in sexual pattern 79.3%, alterations in health maintenance, 72.6%, alteration in comfort, 68.0%, depression, 64.0%, noncompliance with diet therapy, 63.7%, alteration in self concept, 55.6%, and alteration in sleep pattern, 53%. 2. In looking at the effects of home nursing care as demonstrated by changes in the functional categories over the three month period, it was found that of the 11 functional categories, the need level for health perception, nutrition, activity and self concept decreased slightly over the three month period. On the average sleep patterns improved, but restfulness was slightly less and bowel elimination patterns improved but satisfaction with urinary elimination was slightly less. On the other hand, role enactment, sexuality, stress management and spirituality decreased slightly. The only results that were statistically significant at the 0.05 level were improvement in digestion and decrease in pain. No statistically significant changes were found in ability related to ADL, the total ADL score at discharge was 19.78 +/- 8.23, and after 3 months 19.01 +/- 8.12. Considering that a majority of the patients were over 60 years of age and that many had brain or spinal cord injuries, the fact that their ADL ability did not deteriorate after discharge can be interpreted as related to a positive impact by the home health care nurses. Similarly there was a slight but not statistically significant decrease in the quality of life scores between the two test times (147.83 at discharge and 143.02 at the three month period).(ABSTRACT TRUNCATED AT 400 WORDS)

Quality of life attenuates age-related decline in functional status of older adults.

In the present study, we aimed to examine the total and moderating effects of needs-satisfaction-driven quality-of-life (QoL) measure on age-related change in functional status. Participants in the Survey of Health and Retirement in Europe (N = 18,781 at Wave 1) completed a measure of QoL (CASP-12) at baseline and reported their functional status across subsequent three waves using activities of daily living (ADL), instrumental activities of daily living (IADL), and functional limitation indices. Growth-curve model estimates revealed that aged individuals with lower QoL scores at baseline had a steeper increase in disability deficits accumulation and functional limitation progression than their counterparts with a higher sense of QoL. The effects were more pronounced in ADL and IADL disability scales in which QoL moderated both linear and quadratic age-related changes. Higher QoL attenuates processes of functional decline in late adulthood. Practitioners may seek strategies for improving and enhancing patients' QoL, as its salutary effects diffuse beyond psychological experience and include long-term effects on physical functioning.

DiZazzo-Miller, Rosanne; Winston, Kristin; Winkler, Sandra L; Donovan, Mary L

The purpose of this study was to examine the effectiveness of the Family Caregiver Training Program (FCTP) for caregivers of people with dementia. A random assignment control group research design with a 3-mo follow-up was implemented. Thirty-six family caregivers of people with dementia demonstrated an increase in activity of daily living (ADL) knowledge (p < .001) and maintenance of that knowledge 3 mo posttest. Caregiver confidence, regardless of group assignment, improved; however, it was not maintained. Burden, depression, and occupational performance and satisfaction remained unchanged for the intervention group; however, physical health as it pertained to quality of life improved 3 mo posttest (p < .001). Findings demonstrate that the FCTP can effectively provide knowledge to family caregivers on how to assist people with dementia with ADLs. Even when standard care was provided, there was limited information on ADLs that family caregivers faced daily. Copyright © 2017 by the American Occupational Therapy Association, Inc.

This evidence-based review examined the evidence supporting the use of occupation-based interventions to improve areas of occupation and social participation poststroke. A total of 39 studies met the inclusion criteria and were critically evaluated. Most of the literature targeted activity of daily living (ADL)–based interventions and collectively provided strong evidence for the use of occupation-based interventions to improve ADL performance. The evidence related to instrumental ADLs was much more disparate, with limited evidence to support the use of virtual reality interventions and emerging evidence to support driver education programs to improve occupational performance poststroke. Only 6 studies addressed leisure, social participation, or rest and sleep, with sufficient evidence to support only leisure-based interventions. The implications of this review for research, education, and practice in occupational therapy are also discussed. PMID:25553745

Medicare currently penalizes hospitals for high readmission rates for seniors but does not account for common age-related syndromes, such as functional impairment. To assess the effects of functional impairment on Medicare hospital readmissions given the high prevalence of functional impairments in community-dwelling seniors. We created a nationally representative cohort of 7854 community-dwelling seniors in the Health and Retirement Study, with 22,289 Medicare hospitalizations from January 1, 2000, through December 31, 2010. Outcome was 30-day readmission assessed by Medicare claims. The main predictor was functional impairment determined from the Health and Retirement Study interview preceding hospitalization, stratified into the following 5 levels: no functional impairments, difficulty with 1 or more instrumental activities of daily living, difficulty with 1 or more activities of daily living (ADL), dependency (need for help) in 1 to 2 ADLs, and dependency in 3 or more ADLs. Adjustment variables included age, race/ethnicity, sex, annual income, net worth, comorbid conditions (Elixhauser score from Medicare claims), and prior admission. We performed multivariable logistic regression to adjust for clustering at the patient level to characterize the association of functional impairments and readmission. Patients had a mean (SD) age of 78.5 (7.7) years (range, 65-105 years); 58.4% were female, 84.9% were white, 89.6% reported 3 or more comorbidities, and 86.0% had 1 or more hospitalizations in the previous year. Overall, 48.3% had some level of functional impairment before admission, and 15.5% of hospitalizations were followed by readmission within 30 days. We found a progressive increase in the adjusted risk of readmission as the degree of functional impairment increased: 13.5% with no functional impairment, 14.3% with difficulty with 1 or more instrumental activities of daily living (odds ratio [OR], 1.06; 95% CI, 0.94-1.20), 14.4% with difficulty with 1 or more ADL (OR, 1.08; 95% CI, 0.96-1.21), 16.5% with dependency in 1 to 2 ADLs (OR, 1.26; 95% CI, 1.11-1.44), and 18.2% with dependency in 3 or more ADLs (OR, 1.42; 95% CI, 1.20-1.69). Subanalysis restricted to patients admitted with conditions targeted by Medicare (ie, heart failure, myocardial infarction, and pneumonia) revealed a parallel trend with larger effects for the most impaired (16.9% readmission rate for no impairment vs 25.7% for dependency in 3 or more ADLs [OR, 1.70; 95% CI, 1.04-2.78]). Functional impairment is associated with increased risk of 30-day all-cause hospital readmission in Medicare seniors, especially those admitted for heart failure, myocardial infarction, or pneumonia. Functional impairment may be an important but underaddressed factor in preventing readmissions for Medicare seniors.

Importance Medicare currently penalizes hospitals for high rates of readmission for seniors but does not account for common age-related syndromes such as functional impairment. Objectives Given the high prevalence of functional impairments in community-dwelling seniors, we assessed effects of functional impairment on Medicare hospital readmissions. Study Design, Participants, and Setting We created a nationally-representative cohort of 7,854 community-dwelling seniors in the Health and Retirement Study (HRS) with 22,289 Medicare hospitalizations from 2000–2010. Main Outcome and Measurements Outcome was 30-day readmission, assessed by Medicare claims. Main predictor was functional impairment determined from HRS interview preceding hospitalization, stratified into 5 levels: no functional impairments, difficulty with ≥1 instrumental activity of daily living (IADL), difficulty with ≥1 activity of daily living (ADL), dependency (need for help) in 1–2 ADLs, and dependency in ≥3 ADLs. Adjustment variables included age, race, gender, income, and net worth and comorbid conditions (Elixhauser score from Medicare claims), and prior admission. We performed multivariable logistic regression adjusted for clustering at patient level to characterize the association of functional impairments and readmission. Results Mean age 79 (±8; 65–105), 58% female, 85% White, 90% reported ≥3 comorbidities, 86% had ≥1 hospitalization in previous year. Overall, 48% had some level of functional impairment prior to admission and 15% experienced a 30-day readmission. We found a progressive increase in adjusted risk of readmission as the degree of functional impairment increased: 13.5% with no functional impairment, 14.3% with ≥ 1 IADL difficulty (OR 1.06; 95% CI 0.94–1.20), 14.4% with ≥1 ADL difficulty (OR 1.08; 0.96–1.21), 16.5% with dependency in 1–2 ADLs (OR 1.26; 1.11–1.44), and 18.2% with dependency in ≥3 ADLs (1.42; 1.20–1.69). Sub-analysis restricted to patients admitted with conditions targeted by Medicare (heart failure, myocardial infarction, and pneumonia) revealed a parallel trend with larger effects for the most-impaired (16.9% readmission rate for no impairment vs. 25.7% for dependency in ≥3 ADLs, OR 1.70; 1.04–2.78). Conclusions Functional impairment is associated with increased risk of 30-day, all-cause hospital readmission in Medicare seniors, especially those admitted for heart failure, myocardial infarction or pneumonia. Functional impairment on admission may be an overlooked but highly suitable target for interventions to reduce Medicare hospital readmissions. Relevance Functional impairment may be an important but under-addressed factor in preventing readmissions for Medicare seniors. PMID:25642907

Introduction: Calcaneal fractures are caused by high energy trauma and mostly are intra-articular fractures. Nondisplaced intra-articular calcaneal fracture (IACF) can be treated non-operatively. However, displaced intra-articular need to be reduced and fixed anatomically to facilitate early ankle rehabilitation and minimize functional impairment. This study was done to find out the outcome of the IACF patients who underwent operative treatment. Methods: 62 patients with IACF were selected in this study and had been followed up from June 2009 to May 2013. They were placed into two groups; the operative treated and non-operative treated groups. Bilateral ankle lateral view plain radiographs were taken for comparison of the Bohler and Gissane angles. Both groups of patients were assessed by the Maryland Foot Score (MFS) and the SF-36v2 general health survey questionnaire. The ability of the patients to perform activity of daily living (ADL) and /or return to work (RTW) was assessed as well. Results: The operative treatment group of displaced IACF patients achieved no significant better scores in the mean MFS and SF-36v2 mean scores as compared to non operated cases. There was no difference in RTW between the 2 groups, but earlier ADL was recorded in the operated group. However, this study had found 5 associated factors which causes major effect to the patients’ outcome to treatment. Conclusions: The patient’s compliance with post-operative rehabilitation regimen were found to be significantly related with the outcomes. PMID:28611903

A growing number of dependent elderly people is cared for at home by family members. However, long-term caregiving may become an intolerable strain for some families and lead to failure of family care. The aim of the study was to examine if level of physical and mental disability of the patient influences the extent of perceived caregiver burden representing risk factor for negative outcome. 128 elderly patients with disability and dependency (37 men, 91 women, average age 79.9 +/- 6.9 yrs) and 128 their primary caregivers, mostly family members (28.9% men, 71.1% women) were evaluated. Functional status of care recipient was assessed by means of Barthel ADL Index (mean = 70.9 +/- 26.5), IADL Test (mean = 31.4 +/- 23.5) and Mini-Mental State Exam, MMSE (mean = 20.4 +/- 6.5). Average score of Caregiver Burden Interview (CBI) was 34.7 +/- 18.8. According to CBI, 40.6% of caregivers were found under high or even extremely hig level of stress. Level of perceived burden correlated significantly with physical and mental disability level, in decreasing order for IADL, ADL and MMSE (rs = 0.582-0.708, p < 0.001). Caregiver burden of family caregivers is significantly related to the level of functioning and cognitive impairment of care recipient, particularly to his/her ability to perform instrumental activities. Functional decline of elderly patient represents a risk factor which contributes to negative caregiving outcome and institutional placement.

Changes for the new AMA Guides to impairment ratings, 6th Edition: implications and applications for physician disability evaluations.

PubMed

Rondinelli, Robert D

2009-07-01

U.S. Disability Systems share a common procedural approach to the determination of disability for purposes of compensation. The structural and anatomical consequences of the injury or disease are defined and measured according to medical impairment, which is used to estimate the individual's loss in terms of their capacity to perform activities of daily living (ADLs) and, presumptively, their losses in terms of vocational and non-vocational pursuits and quality of life. The physician is traditionally empowered to rate the severity of impairment in terms of a percentage loss to the "whole person" and according to criteria specific to each disability system. Often, the impairment percentage so derived, then is directly translated into a monetary sum for purposes of compensating these losses. The AMA periodically publishes and updates a physician impairment rating guide (the AMA Guides). The 6th Edition, published in 2008, incorporates the definitions and terminology of the ICF and provides a simple means of assessment of ADLs as part of the rating process. It also has shifted the ratings criteria towards a diagnosis-based approach, ostensibly to improve inter-rater consistency and reliability. Further work is needed to refine and validate ADL-based functional assessment tools applicable to medical impairment ratings, and to demonstrate the levels of consistency and reliability of the new rating method. Of equal importance, operational standardization across systems is also needed to enable common criteria and metrics to be developed and applied when determining the non-medical aspects of disability according to vocational and non-vocational pursuits and quality of life. Impairment ratings cannot be optimally designed to serve as the singular determinant of, nor be held solely accountable for, the disability awards.

The Joint Polar Satellite System (JPSS) is the next generation polar-orbiting operational environmental satellite system. The first satellite in the JPSS series of satellites, J-1, is scheduled to launch in early 2017. J1 will carry similar versions of the instruments that are on board of Suomi National Polar-Orbiting Partnership (S-NPP) satellite which was launched on October 28, 2011. The center for Satellite Applications and Research Algorithm Integration Team (STAR AIT) uses the Algorithm Development Library (ADL) to run S-NPP and pre-J1 algorithms in a development and test mode. The ADL is an offline test system developed by Raytheon to mimic the operational system while enabling a development environment for plug and play algorithms. The Perl Chain Run Scripts have been developed by STAR AIT to automate the staging and processing of multiple JPSS Sensor Data Record (SDR) and Environmental Data Record (EDR) products. JPSS J1 VIIRS Day Night Band (DNB) has anomalous non-linear response at high scan angles based on prelaunch testing. The flight project has proposed multiple mitigation options through onboard aggregation, and the Option 21 has been suggested by the VIIRS SDR team as the baseline aggregation mode. VIIRS GEOlocation (GEO) code analysis results show that J1 DNB GEO product cannot be generated correctly without the software update. The modified code will support both Op21, Op21/26 and is backward compatible with SNPP. J1 GEO code change version 0 delivery package is under development for the current change request. In this presentation, we will discuss how to use the Chain Run Script to verify the code change and Lookup Tables (LUTs) update in ADL Block2.

The effect of muscle weakness on the capability gap during gross motor function: a simulation study supporting design criteria for exoskeletons of the lower limb.

Enabling persons with functional weaknesses to perform activities of daily living (ADL) is one of the main challenges for the aging society. Powered orthoses, or exoskeletons, have the potential to support ADL while promoting active participation of the user. For this purpose, assistive devices should be designed and controlled to deliver assistance as needed (AAN). This means that the level of assistance should bridge the capability gap, i.e. the gap between the capabilities of the subjects and the task requirements. However, currently the actuators of exoskeletons are mainly designed using inverse dynamics (ID) based calculations of joint moments. The goal of the present study is to calculate the capability gap for the lower limb during ADL when muscle weakness is present, which is needed for appropriate selection of actuators to be integrated in exoskeletons. A musculoskeletal model (MM) is used to calculate the joint kinematics, joint kinetics and muscle forces of eight healthy subjects during ADL (gait, sit-to-stand, stand-to-sit, stair ascent, stair descent). Muscle weakness was imposed to the MM by a stepwise decrease in maximal isometric force imposed to all muscles. Muscle forces were calculated using static optimization. In order to compensate for muscle weakness, ideal moment actuators that represent the motors of an exoskeleton in the simulation were added to deliver AAN required to perform the task. The ID approach overestimates the required assistance since it relies solely on the demands of the task, whereas the AAN approach incorporates the capabilities of the subject. Furthermore, the ID approach delivers continuous support whereas the AAN approach targets the period where a capability gap occurs. The level of muscle weakness for which the external demands imposed by ADL can no longer be met by active muscle force production, is respectively 40%, 70%, 80% and 30%. The present workflow allows estimating the AAN during ADL for different levels of muscle weakness, which can be used in the mechatronic design and control of powered exoskeletons. The AAN approach is a more physiological approach than the ID approach, since the MM accounts for the subject-specific capabilities of the user.

Background The prevalence and correlates of physical disability and functional limitation among older people have been studied in many developed countries but not in a middle income country such as Malaysia. The present study investigated the epidemiology of physical disability and functional limitation among older people in Malaysia and compares findings to other countries. Methods A population-based cross sectional study was conducted in Alor Gajah, Malacca. Seven hundred and sixty five older people aged 60 years and above underwent tests of functional limitation (Tinetti Performance Oriented Mobility Assessment Tool). Data were also collected for self reported activities of daily living (ADL) using the Barthel Index (ten items). To compare prevalence with other studies, ADL disability was also defined using six basic ADL's (eating, bathing, dressing, transferring, toileting and walking) and five basic ADL's (eating, bathing, dressing, transferring and toileting). Results Ten, six and five basic ADL disability was reported by 24.7% (95% CI 21.6-27.9), 14.4% (95% CI 11.9-17.2) and 10.6% (95% CI 8.5-13.1), respectively. Functional limitation was found in 19.5% (95% CI 16.8-22.5) of participants. Variables independently associated with 10 item ADL disability physical disability, were advanced age (≥ 75 years: prevalence ratio (PR) 7.9; 95% CI 4.8-12.9), presence of diabetes (PR 1.8; 95% CI 1.4-2.3), stroke (PR 1.5; 95% CI 1.1-2.2), depressive symptomology (PR 1.3; 95% CI 1.1-1.8) and visual impairment (blind: PR 2.0; 95% CI 1.1-3.6). Advancing age (≥ 75 years: PR 3.0; 95% CI 1.7-5.2) being female (PR 2.7; 95% CI 1.2-6.1), presence of arthritis (PR 1.6; 95% CI 1.2-2.1) and depressive symptomology (PR 2.0; 95% CI 1.5-2.7) were significantly associated with functional limitation. Conclusions The prevalence of physical disability and functional limitation among older Malaysians appears to be much higher than in developed countries but is comparable to developing countries. Associations with socio-demographic and other health related variables were consistent with other studies. PMID:20716377

Exercise and physical training are known to affect gastrointestinal function and digestibility in horses and can lead to inaccurate estimates of nutrient and energy digestibility when markers are used. The effect of exercise on apparent nutrient digestibility and faecal recoveries of ADL and TiO2 was studied in six Welsh pony geldings subjected to either a low- (LI) or high-intensity (HI) exercise regime according to a cross-over design. Ponies performing LI exercise were walked once per day for 45 min in a horse walker (5 km/h) for 47 consecutive days. Ponies submitted to HI exercise were gradually trained for the same 47 days according a standardized protocol. Throughout the experiment, the ponies received a fixed level of feed and the daily rations consisted of 4.7 kg DM of grass hay and 0.95 kg DM of concentrate. The diet was supplemented with minerals, vitamins and TiO2 (3.0 g Ti/day). Total tract digestibility of DM, organic matter (OM), CP, crude fat, NDF, ADF, starch, sugar and energy was determined with the total faeces collection (TFC) method. In addition, DM and OM digestibility was estimated using internal ADL and the externally supplemented Ti as markers. Urine was collected on the final 2 days of each experimental period. Exercise did not affect apparent digestibility of CP, crude fat, starch and sugar. Digestibility of DM (DMD), OM (OMD), ADF and NDF tended to be lower and DE was decreased when ponies received the HI exercise regime. For all treatments combined, mean faecal recoveries of ADL and Ti were 87.8±1.7% and 99.3±1.7%, respectively. Ti was not detected in the urine, indicating that intestinal integrity was maintained with exercise. Dry matter digestibility estimated with the TFC, ADL and Ti for ponies subjected to LI exercise were 66.3%, 60.3% and 64.8%, respectively, while DMD for HI ponies were 64.2%, 60.3% and 65.2%, respectively. In conclusion, physical exercise has an influence on the GE digestibility of the feed in ponies provided with equivalent levels of feed intake. In addition, the two markers used for estimating apparent DMD and OMD indicate that externally supplemented Ti is a suitable marker to determine digestibility of nutrients in horses performing exercise unlike dietary ADL.

Objective To study whether health-related quality of life (HRQOL), activities of daily living (ADL), and anxiety and depression symptoms affect the risk of hospital admission and potential interactions with having a cancer diagnosis. Methods This study was a prospective observational study with 5-year follow-up and analyzed the follow-up data on hospital admissions until 2010 using baseline data from 227 cognitively intact nursing home (NH) residents (60 of whom had cancer) in 2004–2005. Data on HRQOL were collected by using the Short Form-36 Health Survey, divided into physical component summary (PCS) and mental component summary (MCS), and symptoms of anxiety and depression were collected by using the Hospital Anxiety and Depression Scale (HADS). ADL were obtained from registered observation and sociodemographic variables, diagnoses, and hospital admissions from the NH records. Personal identification numbers were linked to the record systems of the hospitals, thereby registering all hospital admissions. We analyzed the time elapsing between inclusion and the first hospital admission. Results Residents with higher HRQOL (MCS) had significantly more hospital admissions after adjustment for age, sex, marital status, education, and comorbidity. HRQOL (PCS), ADL, depression, and anxiety symptoms were not associated with hospital admissions. Cancer increased the risk after adjustment for all other risk factors but did not increase the effects of MCS, PCS, ADL, or depression or anxiety symptoms. Having a higher level of education and being less than 75 years of age were associated with hospitalization. The residents diagnosed with cancer had the most days in hospital related to diseases of the respiratory system and cancer, and diseases of the circulatory and respiratory systems were more frequent among the residents without a cancer diagnosis. Conclusion Better self-reported HRQOL (MCS) was associated with hospital admissions, whereas self-reported HRQOL (PCS), ADL, and depression and anxiety symptoms were not. Cancer increased the risk but not the effects of MCS, PCS, ADL, or depression or anxiety symptoms. Having a higher level of education and being less than 75 years of age were also associated with hospitalization. PMID:27022249

There are limited data regarding outcomes and return to sports after surgery for acute versus chronic proximal hamstring ruptures. Surgery for chronic proximal hamstring ruptures leads to improved outcomes and return to sports but at a lower level than with acute repair. Proximal hamstring reconstruction with an Achilles allograft for chronic ruptures is successful when direct repair is not possible. Cohort study; Level of evidence, 3. Between 2002 and 2012, a total of 72 patients with a traumatic proximal hamstring rupture (51 acute, 21 chronic) underwent either direct tendon repair with suture anchors (n = 58) or Achilles allograft tendon reconstruction (n = 14). Results from the Single Assessment Numeric Evaluation (SANE) for activities of daily living (ADL) and sports-related activities, Short Form-12 (SF-12), visual analog scale (VAS), and a patient satisfaction questionnaire were obtained. The mean time to surgery in the chronic group was 441.4 days versus 17.8 days in the acute group. At a mean follow-up of 45 months, patients with chronic tears had inferior sports activity scores (70.2% vs 80.3%, respectively; P = .026) and a trend for decreased ADL scores (86.5% vs 93.3%, respectively; P = .085) compared with those with acute tears. Patients with chronic tears, however, reported significant improvements postoperatively for both sports activity scores (30.3% to 70.2%; P < .01) and ADL scores (56.1% to 86.5%; P < .01). Greater than 5 to 6 cm of retraction in the chronic group was predictive of the need for allograft reconstruction (P = .015) and resulted in ADL and sports activity scores equal to those of chronic repair (P = .507 and P = .904, respectively). There were no significant differences between groups in SF-12, VAS, or patient satisfaction outcomes (mean, 85.2% satisfaction overall). Acute repair was superior to chronic surgery with regard to return to sports. Acute and chronic proximal hamstring repair and allograft reconstruction had favorable results for ADL. For low-demand patients or those with medical comorbidities, delayed repair or reconstruction might be considered with an expected 87% return to normal ADL. For patients who desire to return to sports, acute repair is recommended. © 2014 The Author(s).

Background Growing attention in the past few decades has focused on improving care quality and quality of life for nursing home residents. Many traditional nursing homes have attempted to transform themselves to become more homelike emphasizing individualized care. This trend is referred to as nursing home culture change in the U.S. A promising culture change nursing home model, the Green House (GH) nursing home model, has shown positive psychological outcomes. However, little is known about whether the GH nursing home model has positive effects on physical function compared to traditional nursing homes. Objectives To examine the longitudinal effects of the GH nursing home model by comparing change patterns of ADL function over time between GH home residents and traditional nursing home residents. Design A retrospective longitudinal study. Settings Four GH organizations (nine GH units and four traditional units). Participants A total of 242 residents (93 GH residents and 149 traditional home residents) who had stayed in the nursing home at least six months from admission. Methods The outcome was ADL function, and the main independent variable was the facility type in which the resident stayed: a GH or traditional unit. Age, gender, comorbidity score, cognitive function, and depressive symptoms at baseline were controlled. All of these measures were from a minimum dataset. Growth curve modeling and growth mixture modeling were employed in this study for longitudinal analyses. Results The mean ADL function showed deterioration over time, and the rates of deterioration between GH and traditional home residents were not different over time. Four different ADL function trajectories were identified for 18 months, but there was no statistical difference in the likelihood of being in one of the four trajectory classes between the two groups. Conclusions Although GH nursing homes are considered to represent an innovative model changing the nursing home environment into more person-centered, this study did not demonstrate significant differences in ADL function changes for residents in the GH nursing homes compared to traditional nursing homes. Given that the GH model continues to evolve as it is being implemented and variations within and across GH homes are identified, large-scale longitudinal studies are needed to provide further relevant information on the effects of the GH model.

Objectives: The UPDRS is a commonly used neurological measurement to assess the presence and severity of parkinsonian symptoms. It has also been used to assess symptoms associated with Mn exposure. Objectives: to determine 1) if movement disorder symptoms were associated with UPDRS: Activities of Daily Living (ADL) and Motor abnormalities; and 2) which symptoms were most related to increased abnormalities on these UPDRS subscales. Participants & Methods: Correlations between self-reported movement disorder symptoms from a health questionnaire and scores obtained on UPDRS: ADL and Motor subscales, and the Bradykinesia domain of the Motor subscale, were assessed during a medical examination among 185 Mn-exposed participants from two Ohio towns. Partial correlations were used for statistical analyses, controlling for age, sex, education and a history of musculoskeletal disease.Results: The presence of movement disorder symptoms was positively associated with ADL (pr =0.647, p = <0.001), Motor (pr =0.449, p = <0.001), and Bradykinesia (pr =0.418, p = <0.001) domains on the UPDRS. Specific movement disorder symptoms most strongly associated with increased ADL and Motor scores included having difficulty getting out of chairs (pr =0.458, p = <0.001), writing (pr =0.481, p = <0.001), skilled movements (pr =0.478, p = <0.001), loss of coordination/balance (pr =0.457, p = <0.001), changes in walking (pr =0.412, p = <0.001) and slowness of movement (pr =0.539, p = <0.0

To describe patterns of prosthesis wear and perceived prosthetic usefulness in adult acquired upper-limb amputees (ULAs). To describe prosthetic skills in activities of daily life (ADL) and the actual use of prostheses in the performance of ADL tasks. To estimate the influence of prosthetic skills on actual prosthesis use and the influence of background factors on prosthetic skills and actual prosthesis use. Cross-sectional study analysing population-based questionnaire data (n = 224) and data from interviews and clinical testing in a referred/convenience sample of prosthesis-wearing ULAs (n = 50). Effects were analysed using linear regression. 80.8% wore prostheses. 90.3% reported their most worn prosthesis as useful. Prosthetic usefulness profiles varied with prosthetic type. Despite demonstrating good prosthetic skills, the amputees reported actual prosthesis use in only about half of the ADL tasks performed in everyday life. In unilateral amputees, increased actual use was associated with sufficient prosthetic training and with the use of myoelectric vs cosmetic prostheses, regardless of amputation level. Prosthetic skills did not affect actual prosthesis use. No background factors showed significant effect on prosthetic skills. Most major ULAs wear prostheses. Individualised prosthetic training and fitting of myoelectric rather than passive prostheses may increase actual prosthesis use in ADL.

Abstract With advanced technologies in hand, there exist potential applications and services built around monitoring activities of daily living (ADL) of elderly people at nursing homes. Most of the elderly people in these facilities are suffering from different chronic diseases such as dementia. Existing technologies are mainly focusing on non-medication interventions and monitoring of ADL for addressing loss of autonomy or well-being. Monitoring and managing ADL related to cognitive behaviors for non-medication intervention are very effective in improving dementia patients' conditions. However, cognitive functions of patients can be improved if appropriate recommendations of medications are delivered at a particular time. Previously we developed the Secured Wireless Sensor Network Integrated Cloud Computing for Ubiquitous-Life Care (SC3). SC3 services were limited to monitoring ADL of elderly people with Alzheimer's disease and providing non-medication recommendations to the patient. In this article, we propose a system called the Smart Clinical Decision Support System (CDSS) as an integral part of the SC3 platform. Using the Smart CDSS, patients are provided with access to medication recommendations of expert physicians. Physicians are provided with an interface to create clinical knowledge for medication recommendations and to observe the patient's condition. The clinical knowledge created by physicians as the knowledge base of the Smart CDSS produces recommendations to the caregiver for medications based on each patient's symptoms. PMID:25559934

This study was conducted to assess daily living activities, pressure sores and risk factors. This was a descriptive study. The study was conducted at a rehabilitation center with 188 individuals participating in the study. Data were collected with a questionnaire form, Activities of Daily Living Scale (ADLS), Instrumental Activities of Daily Living Scale (IADLS) and Braden Risk Assessment Scale (BRAS). Among the participants, 48.9% were dependent according to activities of daily living and 71.8% were dependent on instrumental activities of daily living. It was noted that 4.8% had pressure sores and 38.8% were at high risk. A strong and positive correlation was found among ADLS, IADLS, and BRAS scores (p < .001). Participants who had a low body mass index, had lived at the rehabilitation center for a long time, and were fed on regime 1 or 2, had a higher risk of developing pressure sores (p < .001). Individuals who were dependent according to ADLS and IADLS were at increased risk for the development of pressure sores. Individuals who are treated at rehabilitation centers should be periodically assessed in terms of risk. Pressure sore development can be prevented with appropriate nursing interventions. To reduce the risk of developing pressure sores, nurses should describe the individual's degree of dependency according to ADLS and IADLS and initiate preventive nursing care. © 2014 Association of Rehabilitation Nurses.

This manuscript assesses whether the Veterans Administration Rating System (VADR) correlates with self-reported activities of daily living (ADL) used in the National Survey of Veterans and likelihood of employment. Veterans' disability benefits are determined based on a single-index standardized rating scheme, measured at time of discharge. The primary aim of this study was to assess how this single-index rating of disability for veterans compares to multidimensional measures of disability (ADL and instrumental activities of daily living [IADL]). The relationship between disability ratings and labor market outcomes such as job search behavior and the likelihood of being employed was assessed. Successful labor market reintegration requires both physical/mental well-being, we examined the extent that VADR can capture the relationship between job market behavior and measures of mental/physical health. Kernel regression estimates were obtained of the likelihood of working/looking for work. Mean numbers of IADL and ADL difficulties and medical conditions were positively associated with VADR (p-trend < 0.001). An inverse relationship was observed with VADR and predicted probability of working (p-trend < 0.001). The combination of >4 ADL/IADL deficits and mental health diagnosis increased the likelihood of not working. The probability of not working correlated with VADR when VADR was greater than 40%.

The effects of 150 kilogray (kGy) of γ irradiation on cell-wall constituents of cottonwood (CW), lentils straw (LS), apple pruning products (AP) and olive cake (OC) were investigated. Samples were irradiated by γ irradiation at a dose level of 150 kGy under identical conditions of temperature and humidity and analyzed for crude fibre (CF), neutral-detergent fibre (NDF), acid detergent fibre (ADF) and acid-detergent lignin (ADL). The results indicate that γ irradiation decreased CF contents by about 29% for CW, LS and AP and by 17% for OC. NDF values were also decreased by about 4% for CW and OC, and by about 12% for LS and AP. γ Irradiation treatment also decreased ADF values only for CW by 8%. ADL contents decreased by 8% for CW and 5% for OC with no effects for LS and AP. The percentage of cellulose (CL): CF ratio increased by 30, 34, 38 and 20% for CW, LS, AP and OC, respectively. Also, the percentage of hemicellulose (HCL): CF increased by 57% for CW and 16% for OC and decreased by 7% for LS and AP. The percentage of HCL: ADL increased by 22% for CW but decreased by 33% for LS and AP with no changes for OC. There were no changes in CL: ADL ratio for all residues.

Previous studies have found that social cohesion and trust (SCT) were associated with psychological well-being and physical health. In this study, we investigated the associations between SCT and mental and physical health among community-dwelling elderly in a town in southern Taiwan. The study population consisted of 149 community-dwelling elderly aged 65 years and older (68 men, 81 women; mean age, 75.4 ± 6.1 years) residing in the town of Dashe in southern Taiwan. Activities of daily living (ADL), SCT, depression, subjective quality of life (QOL), current medical status, past medical history, and health behaviors were assessed in face-to-face interviews. Objective neurobehavioral functions were assessed using the timed up & go (TUG) test, functional reach test, and handgrip test. Scores for ADL and Geriatric Depression Scale (GDS) were significantly correlated with SCT, and SCT was significantly correlated with all subjective QOL items. In addition, a strong correlation was observed between SCT and relationship with friends. Values for SCT (median ≥ 20) were significantly associated with both subjective sense of health (median ≥ 68) and subjective happiness (median ≥ 73) after adjusting for age, sex, and ADL. SCT is an important variable that influences self-rated health and happiness, independently of ADL, age, and sex. When assessing geriatric psychological function, SCT should be examined more carefully, given its association with subjective sense of health and happiness, depression, and physical function.

Background Occupational therapy (OT) is a critical component of the rehabilitation process after spinal cord injury (SCI), the constitution of which has not been studied or documented in full detail previously. Objective To describe the type and distribution of SCI rehabilitation OT activities, including the amount of time spent on evaluation and treatment, and to discuss predictors (patient and injury characteristics) of the amount of time dedicated to OT treatment activities. Methods Six inpatient rehabilitation centers enrolled 600 patients with traumatic SCI in the first year of the SCIRehab. Occupational therapists documented 32 512 therapy sessions including time spent and specifics of each therapeutic activity. Analysis of variance and contingency tables/chi-square tests were used to test differences across neurologic injury groups for continuous and categorical variables. Results SCIRehab patients received a mean total of 52 hours of OT over the course of their rehabilitation stay. Statistically significant differences among four neurologic injury groups were seen in time spent on each OT activity. The activities that consumed the most OT time (individual and group sessions combined) were strengthening/endurance exercises, activities of daily living (ADLs), range of motion (ROM)/stretching, education, and a grouping of ‘therapeutic activities’ that included tenodesis training, fine motor activities, manual therapy, vestibular training, edema management, breathing exercise, cognitive retraining, visual/perceptual training desensitization, and don/doff adaptive equipment. Seventy-seven percent of OT work occurred in individual treatment sessions, with the most frequent OT activity involving ADLs. The variation in time (mean minutes per week) spent on OT ROM/stretching, ADLs, transfer training, assessment, and therapeutic activities can be explained in part by patient and injury characteristics, such as admission Functional Independence Measure (FIM) score, neurologic injury group, and the medical severity of illness score. Conclusion OT treatment patterns for patients with traumatic SCI show much variation in activity selection and time spent on activities, within and among neurologic level of injury groups. Some of the variation can be explained by patient and injury characteristics. Almost all patients with SCI participated in strengthening/endurance and ROM/stretching exercises during OT treatment and these two activities are where the most time was spent when therapy provided in individual and group settings was combined. ADL work consumed the most time in individual therapy sessions. PMID:21675355

To systematically review the impact of reablement, reactivation, rehabilitation, and restorative (4R) programs for older adults in receipt of home care services. Systematic review. We searched the following electronic bibliographic databases: MEDLINE, EMBASE, PsycINFO, CINAHL (Cumulative Index to Nursing and Allied Health), SPORTDiscus and The Cochrane Library and reference lists. Randomized controlled trials that describe original data on the impact of home-based rehabilitative care and were written in English. Fifteen studies were identified. Study details were recorded using a predefined data abstraction form. Methodological quality was assessed by 2 independent reviewers. If there were discrepancies, a third author resolved these. Given the tailored and personalized approach of the 4R interventions, a range of primary outcomes were assessed, including functional abilities, strength, gait speed, social support, loneliness, and the execution of activities of daily living (ADL) and instrumental ADL (IADL). 4R interventions are intended to reduce the long-term use of home care services. As such, health care resource utilization will be assessed as a secondary outcome. There are 2 distinct clusters of interventions located in this systematic review (defined by hospitalizations): (1) "hospital to home" programs, in which participants are discharged from hospital wards with a 4R home care, and (2) those that focus on clients receiving home care without a hospital stay immediately preceding. Reflecting the highly tailored and personalized nature of 4R interventions, the studies included in this review assessed a wide range of outcomes, including survival, place of residence, health care service usage, functional abilities, strength, walking impairments, balance, falls efficacy and rates of falls, pain, quality of life, loneliness, mental state, and depression. The most commonly reported and statistically significant outcomes were those pertaining to the service usage and functional abilities of participants. From cost savings to improvements in clinical outcomes, 4R interventions show some promise in the home care context. However, there are several key issues across studies, including questions surrounding the generalizability of the results, in particular with respect to the ineligibility criteria for most interventions; the lack of information provided on the interventions; and lack of information on staff training.

Objectives To investigate the effects of a high-intensity functional exercise program on independence in activities of  daily living (ADLs) and balance in older people with dementia and whether exercise effects differed between dementia types. Design Cluster-randomized controlled trial: Umeå Dementia and Exercise (UMDEX) study. Setting Residential care facilities, Umeå, Sweden. Participants Individuals aged 65 and older with a dementia diagnosis, a Mini-Mental State Examination score of 10 or greater, and dependence in ADLs (N = 186). Intervention Ninety-three participants each were allocated to the high-intensity functional exercise program, comprising lower limb strength and balance exercises, and 93 to a seated control activity. Measurements Blinded assessors measured ADL independence using the Functional Independence Measure (FIM) and Barthel Index (BI) and balance using the Berg Balance Scale (BBS) at baseline and 4 (directly after intervention completion) and 7 months. Results Linear mixed models showed no between-group effect on ADL independence at 4 (FIM=1.3, 95% confidence interval (CI)=−1.6–4.3; BI=0.6, 95% CI=−0.2–1.4) or 7 (FIM=0.8, 95% CI=−2.2–3.8; BI=0.6, 95% CI=−0.3–1.4) months. A significant between-group effect on balance favoring exercise was observed at 4 months (BBS=4.2, 95% CI=1.8–6.6). In interaction analyses, exercise effects differed significantly between dementia types. Positive between-group exercise effects were found in participants with non-Alzheimer's dementia according to the FIM at 7 months and BI and BBS at 4 and 7 months. Conclusion In older people with mild to moderate dementia living in residential care facilities, a 4-month high-intensity functional exercise program appears to slow decline in ADL independence and improve balance, albeit only in participants with non-Alzheimer's dementia.

To determine the effect of asthma on functional limitations of older adults in the United States. Analyses were conducted with data from the Asthma Beliefs and Literacy in the Elderly study, a prospective cohort study of people aged 60 and older with asthma. Participants were recruited from urban primary care and pulmonary specialty practices in New York City and Chicago between 2010 and 2012. Individuals aged 60 and older with asthma (380 women, 72 men, mean age 67.5 ± 6.8 (range 60-98), 40% Latino, 30% black). Characteristics of participants with and without activity of daily living (ADL) limitations were compared using the chi-square test. Generalized estimating equations were used to model the relationships between poor asthma control (Asthma Control Questionnaire (ACQ) score >1.5) and severity of airway obstruction (forced expiratory volume in 1-second (FEV1 )) and number of ADL limitations. Participants with one or more ADL limitations were more likely to be female (90% vs 81%, P = .02) and Latino (58% vs 32%, P < .001), have less than a high school education (53% vs 27%, P < .001) and an income of $1,350 per month or less (79% vs 46%, P < .001), and be unmarried (78% vs 64%, P = .003). In the adjusted analysis, poorer ACQ scores (odds ratio (OR) = 1.6, 95% confidence interval (CI) = 1.0-2.4; P = .05) but not severity of airway obstruction (OR = 1.1, 95% CI = 0.6-1.9) was associated with greater ADL limitations. Older adults reporting poor asthma control are more likely to have ADL limitations than those with controlled asthma, although one-time spirometry may not adequately identify those at risk of physical impairment from asthma. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

Few studies have investigated the relationships between aphasia and activities of daily living (ADLs) in stroke patients. This study was aimed firstly to determine which task within the ADLs has poorer functional recovery in stroke patients with aphasia after rehabilitation, second to identify which specific task is related to aphasia. This is a prospective and observational study. Inpatients of our Rehabilitation Unit. The study was carried out in 219 patients with primary diagnosis of stroke with (104) and without aphasia (115). All patients underwent usual rehabilitation. Aachen Aphasia Test and Functional Independence Measure scale were used to assess severity of aphasia and ADLs, respectively. Gain in ADLs was the main outcome measure. At the end of rehabilitation patients with aphasia had lower gain in bathing, dressing upper body, dressing lower body, toileting, stair climbing, and higher gain in social interaction, problem solving, and memory with respect to patients without aphasia. However, when data were adjusted for side of hemiplegia, Fugl-Meyer score and trunk control test, patients with aphasia showed lower gain in dressing upper body (P=0.027), dressing lower body (P=0.009), lower toileting (P=0.027), and higher gain in social interaction (P<0.001). In the multivariate regression analysis, aphasia was an important determinant of gain in bathing (β=0.26), dressing upper body (β=0.24), dressing lower body (β=0.22), lower toileting (β=0.22), and social interaction (β=-0.29). The current study points out that, after usual rehabilitation, the patients with aphasia show a poor gain in personal care activities and higher gain in social interaction. Knowledge of these findings: 1) can guide the rehabilitation team in selecting specific and appropriate therapies aimed to give patient with aphasia the highest possible functional independence in ADLs; 2) is useful to family members and social rehabilitation services for domiciliary management of patients with aphasia.

To evaluate reproducibility, validity, and responsiveness of the Hip Outcome Score (HOS) in patients with end-stage hip osteoarthritis. In a cohort of 157 consecutive patients (mean age 66 years; 79 women) undergoing total hip replacement, the HOS was tested for the following measurement properties: feasibility (percentage of evaluable questionnaires), reproducibility (intraclass correlation coefficient [ICC] and standard error of measurement [SEM]), construct validity (correlation with the Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC], Oxford Hip Score [OHS], Short Form 12 health survey, and University of California, Los Angeles activity scale), internal consistency (Cronbach's alpha), factorial validity (factor analysis), floor and ceiling effects, and internal and external responsiveness at 6 months after surgery (standardized response mean and change score correlations). Missing items occurred frequently. Five percent to 6% of the HOS activities of daily living (ADL) subscales and 20-32% of the sport subscales could not be scored. ICCs were 0.92 for both subscales. SEMs were 1.8 points (ADL subscale) and 2.3 points (sport subscale). Highest correlations were found with the OHS (r = 0.81 for ADL subscale and r = 0.58 for sport subscale) and the WOMAC physical function subscale (r = 0.83 for ADL subscale and r = 0.56 for sport subscale). Cronbach's alpha was 0.93 and 0.88 for the ADL and sport subscales, respectively. Neither unidimensionality of the subscales nor the 2-factor structure was supported by factor analysis. Both subscales showed good internal and external responsiveness. The HOS is reproducible and responsive when assessing patients with end-stage hip osteoarthritis in whom the items are relevant. However, based on the large proportion of missing data and the findings of the factor analysis, we cannot recommend this questionnaire for routine use in this target group.

To examine the role of health conditions, socioeconomic, and socioenvironmental factors in explaining gender differences in physical disability among older adults. We compared 412 women and 328 men residing in underprivileged communities in Lebanon on their activities of daily living (ADL), instrumental activities of daily living (IADL), and physical tasks (PT). Binary logistic regression analyses adjusting for possible explanatory covariates were conducted sequentially. Women showed higher prevalence rates of ADL, IADL, and PT compared to men. Gender disparities in ADL disability were explained by chronic-disease risk factors and health conditions (OR = 1.46; 95% CI = 0.94-2.25). The odds of disability in IADL and PT remained significantly higher for women compared to men after accounting for all available covariates. These results suggest underlying differences in functional status between women and men, yet, may have been influenced by the sensitivity of the measures to the social context and gendered environment surrounding daily activities.

Spontaneous visual recovery is rare after cortical blindness. While visual rehabilitation may improve performance, no visual therapy has been widely adopted, as clinical outcomes are variable and rarely translate into improvements in activities of daily living (ADLs). We explored the potential value of a novel rehabilitation approach "cognitive therapeutic exercises" for cortical blindness. The subject of this case study was 48-year-old woman with cortical blindness and tetraplegia after cardiac arrest. Prior to the intervention, she was dependent in ADLs and poorly distinguished shapes and colors after 19 months of standard visual and motor rehabilitation. Computed tomographic images soon after symptom onset demonstrated acute infarcts in both occipital cortices. The subject underwent 8 months of intensive rehabilitation with "cognitive therapeutic exercises" consisting of discrimination exercises correlating sensory and visual information. Visual fields increased; object recognition improved; it became possible to watch television; voluntary arm movements improved in accuracy and smoothness; walking improved; and ADL independence and self-reliance increased. Subtraction of neuroimaging acquired before and after rehabilitation showed that focal glucose metabolism increases bilaterally in the occipital poles. This study demonstrates feasibility of "cognitive therapeutic exercises" in an individual with cortical blindness, who experienced impressive visual and sensorimotor recovery, with marked ADL improvement, more than 2 years after ischemic cortical damage.Video Abstract available for additional insights from the authors (see Video, Supplemental Digital Content 1, available at: http://links.lww.com/JNPT/A173).

To compare the practicality, reliability, validity, and responsiveness of the timed up and go (TUG), one-leg stand (OLS), functional reach (FR), and Tinetti balance (TB) performance measures in people aged 65 and older. A prospective study. Shin-Sher Township of Taichung County, west-central Taiwan. Twelve hundred community-dwelling older people. During an initial assessment at their residences, participants were interviewed for demographics, cognition, fall history, use of a walking aid, and activities of daily living (ADLs), in addition to completing the four balance tests. Falls were ascertained by telephone every 3 months for a 1-year follow-up; the four balance measures and ADLs were also reassessed at the end of the follow-up year. Of the four balance measures, the OLS had the lowest participation rate, and participation of people who were cognitively impaired had fallen in the previous year, used a walking aid, or suffered from an ADL disability was lower than for their counterparts. The time to complete the tests ranged from 58 seconds for OLS, to 160 seconds for the TB. All four balance measures exhibited excellent test-retest reliability and discriminant validity but poor responsiveness to fall status. The TB showed better discriminant, convergent, and predictive validities and responsiveness to ADL changes than the other three tests. According to psychometric properties, the most suitable performance measure for evaluating balance in community-dwelling older people was the TB, followed by the TUG.

ABSTRACT Objective: To assess the short- and medium-term effects of the posture education program (PEP) for students of elementary school regarding theoretical knowledge and posture during activities of daily living (ADLs). Methods: The sample consisted of 38 students (aged 8-12 years) in the third grade of elementary school in Porto Alegre, Rio Grande do Sul (Southern Brazil). The children were evaluated in three moments: prior to attending the PEP (pretest); after attending the PEP (post-test); and five months after the conclusion of the PEP, immediately after a learning review of four lessons (five months follow-up). The posture during ADLs and the theoretical knowledge about spine and body posture were assessed, based on specific instruments (layout for assessing the dynamic posture - LADy; and questionnaire). The Friedman test, post hoc Wilcoxon test, and Bonferroni correction were applied to identify the differences among the evaluative moments, as they are statistically significant at α<0.05. Results: No statistically significant difference was found between the post-test and follow-up concerning the theoretical knowledge. In addition, no statistically significant difference was found between post-test and follow-up in relation to ADLs; however, the performance of students was higher in the post-test and follow-up, when compared with the pretest. Conclusions: Immediately after the PEP’s conclusion, the students improved their posture in ADLs. These positive effects and the theoretical knowledge were retained in the follow-up (after the review lessons). PMID:28977326

Background This study examined the association between cardiac structure and function and the deterioration in activities of daily living (ADLs) in an age-homogenous, community-dwelling population of patients born in 1920-1921 over a five-year follow-up period. Design Longitudinal cohort study. Methods Patients were recruited from the Jerusalem Longitudinal Cohort Study, which has followed an age-homogenous cohort of Jerusalem residents born in 1920-1921. Patients underwent home echocardiography and were followed up for five years. Dependence was defined as needing assistance with one or more basic ADL. Standard echocardiographic assessment of cardiac structure and function, including systolic and diastolic function, was performed. Reassessment of ADLs was performed at the five-year follow-up. Results A total of 459 patients were included in the study. Of these, 362 (79%) showed a deterioration in at least one ADL at follow-up. Patients with functional deterioration had a significantly higher left ventricular mass index and left atrial volume with a lower ejection fraction. There was no significant difference between the diastolic parameters the groups in examined. When the data were examined categorically, a significantly larger percentage of patients with functional decline had an abnormal left ventricular ejection fraction and left ventricular hypertrophy. The association between left ventricular mass index and functional decline remained significant in all multivariate models. Conclusions In this cohort of the oldest old, an elevated left ventricular mass index, higher left atrial volumes and systolic, but not diastolic dysfunction, were predictive of functional disability.

to determine whether restoration of sensation, impaired due to diabetic peripheral neuropathy (DPN), would reduce the number of falls and the fear of falling and improve activities of daily living (ADL) in a Medicare-aged population. retrospective cohort study of patients with documented, monochromatic near-infrared phototherapy (MIRE)-mediated, symptomatic reversal of DPN. responses to a health status questionnaire following symptomatic reversal of DPN. 252 patients (mean age 76 years) provided health information following symptomatic reversal of diabetic neuropathy (mean duration 8.6 months). incidence of falls and fear of falling decreased within 1 month after reversal of peripheral neuropathy and remained low after 1 year. Likewise, improved ADL were evident soon after reversal of peripheral neuropathy and showed further improvement after 1 year. Overall, reversal of peripheral neuropathy in a clinician's office and subsequent use of MIRE at home was associated with a 78% reduction in falls, a 79% decrease in balance-related fear of falling and a 72% increase in ADL (P < 0.0002 for all results). reversal of peripheral neuropathy is associated with an immediate reduction in the absolute number of falls, a reduced fear of falling and improved ADL. These results suggest that symptomatic reversal of diabetic neuropathy will have a substantial favourable, long-term socioeconomic impact on patients with DPN and the Medicare system, and improve the quality of life for elderly patients with diabetes and peripheral neuropathy.

Procedures for health facility-based management of lymphoedema and adenolymphangitis (ADL) have proved very effective in some countries. Unfortunately, in resource-poor communities of Africa where health facilities are few, overburdened and inaccessible, an alternative approach is required. Community-based care (CC), patient care (PC) and health facility care (HC) approaches were compared. In the CC arm, communities were required to select one of their members for care-giving to its affected members, while in the PC, participants were allocated to groups under a leader with responsibility for care giving to group members. In HC, care was given by the nearest health facility. Caregivers from the three arms were trained and supplies were kept at the local government health office. At the sixth month of intervention, 325 lymphoedema and adenolymphangitis patients had been recruited into the study as participants. Within 12 months, compliance with hygiene practices increased from 29.4% to 62.6% and ADL episodes declined from 43.1% to 4.4% in the community designs arm and the cost on the health system was minimal. However, in the patient and health care arms, compliance and accessibility to supplies was severely affected by poor coordination, delay in resource collection leading to very minimal effect on lesions, odour, ADL frequency and duration. Participants abandoned the health facilities after the second visit. Community care approach was more culturally acceptable and effective for the management lymphoedema and ADL than other approaches.

As physical restraints should only be used in exceptional cases, there is an urgent need for alternatives to restraint use. Surveillance technology could be such an alternative. This study explored whether nursing-home residents with dementia subjected to surveillance technology had better quality of life scores for mood, behavioral and societal dimensions than residents with physical restraints. Quality of life was assessed longitudinally, with three measurements in six psychogeriatric nursing homes of residents with surveillance technology (n = 170) and residents with physical restraints (n = 22). QUALIDEM subscales were used to measure five dimensions of quality of life. Multilevel longitudinal univariate and multivariate regression techniques were used to analyze the data. Because physical restraints were almost exclusively used in residents with low activities of daily living (ADL) independency (18 of the 22), we restricted the regression analyses to residents with a Barthel Index score ≤ 5 (overall n = 53). Univariate results showed that highly ADL-dependent residents with surveillance technology had significantly more positive affect than highly ADL-dependent residents with physical restraints. However, this difference proved to be no longer significant after adjustment for the confounders: age, sex and stage of dementia.

Assessment of activities of daily living (ADL) can be helpful for designing individualized rehabilitation programs for disabled individuals. Measuring and comparing the basic ADL (BADL) and instrumental ADL (IADL) independence between middle aged and senior Iranian blind war survivors (IBWS) was the aim of this study. This cross-sectional study assessed BADL and IADL of 312 blind war survivors, using the Barthel Index and the Lawton-Bordy scale. Data collection was carried out in a recreational event for the blind war survivors in Mashhad, Iran, 2008. The majority of the participants were male (99%), and more than 80% had multiple injuries. None of them were independent in all BADL and IADL. Older groups were more dependent in IADL such as telephone use, drug management, financial management, and BADL such as walking on uneven surfaces, bed/chair transfer and using stairs. The functional status and activities' level differences between those aged younger than 50 years and those aged older than 50 years were significant (P<0.05). In the present study, all the IBWS were dependent in at least one ADL. Multiple physical injuries could be one of the main reasons for the dependency in this group. IBWS aged older than 50 years were considerably more dependent in their BADL and IADL than the younger group. It appears that starting the fifth decade of age in IBWS might cause some considerable decrease in their function. Training and individualized rehabilitation programs are warranted. © 2012 Japan Geriatrics Society.

To describe the level of need and divertibility of newly admitted nursing home residents, describe the factors that drive need, and describe the outcomes of residents across different levels of need. Retrospective cohort study. A total of 640 publicly funded nursing homes (also known as long-term care facilities) in Ontario, Canada. All newly admitted residents between January 1, 2010 and March 1, 2012. We categorized residents into 36 groups based on different levels of (1) cognitive impairment, (2) difficulty in activities of daily living (ADL), (3) difficulty in instrumental ADLs, and (4) whether or not they had a caregiver at home. Residents were then categorized as having low, intermediate, or high needs; applying results from previous "Balance of Care" studies, we also captured the proportion who could have been cost-effectively diverted into the community. We then contrasted the characteristics of residents across the needs and divertible groupings, and compared 4 outcomes among these groups: hospital admissions, emergency department visits, mortality, and return to home. A population-level cohort of 64,105 incident admissions was captured. About two-thirds had great difficulty performing ADLs (65%) and had mild to severe cognitive impairment (66%); over 90% had great difficulty with instrumental ADLs. Just less than 50% of the new admissions were considered to be residents with high care needs (cognitively impaired with great ADL difficulty), while only 4.5% (2880 residents) had low care needs (cognition and ADL intact). Those with dementia (71.0%) and previous stroke (21.5%) were over-represented in the high needs group. Those that cannot be divertible to anywhere else but an institution with 24 hour nursing care comprised 41.3% (n = 26,502) of residents. Only 5.4% (n = 3483), based on community resources available, could potentially be cost-effectively diverted to the community. Those at higher needs experienced higher rates of mortality, higher total cost across all health sectors, and lower rates of return to home. The majority of those admitted into nursing homes have high levels of need (driven largely by dementia and stroke) and could not have their needs met cost-effectively elsewhere, suggesting that the system is at capacity. Caring for the long-term care needs of the aging population should consider the balance of investments in institution and community settings.

To perform a cross-cultural adaptation and translation of the original version of the Activities of Daily Living Scale of the Knee Outcome Survey into Simplified Chinese and validate of the Simplified Chinese version. The original version was translated and cross-culturally adapted into Simplified Chinese according to the guidelines and the recommendations of the American Academy of Orthopaedic Surgeons Outcome Committee. A total of 213 patients (96 male, 117 female) were selected to participate in our investigation. The inclusion criteria were as follows: 18 years of age and older, able to speak Chinese Mandarin and read Simplified Chinese, and referred to physical therapy for evaluation and treatment for a knee disorder. The exclusion criteria were as follows: patients who had disorders or impairments involving both knees, patients who had other conditions that could affect lower extremity function, patients with physical therapy related to the knee in the previous 1 month, and patients with psychological problems. Each participant was asked to complete the Knee Outcome Survey Activities of Daily Living Scale (KOS-ADLS), International Knee Documentation Committee Subjective Knee Form, Western Ontario and McMaster Universities Osteoarthritis Index, and Short Form 36 forms and to provide baseline demographic data. Each participant completed the KOS-ADLS twice on 2 nonconsecutive days for reliability evaluation. A portion of the participants (n = 161) finished the KOS-ADLS a third time 4 weeks after physical treatment to test responsiveness. The original version of the KOS-ADLS was well adapted and translated into Simplified Chinese. Simplified Chinese of KOS-ADLS was shown to have good internal consistency (Cronbach's alpha = 0.855 to 0.929), great test-retest reliability (intraclass correlation coefficient = 0.935 to 0.961), high construct validity as we hypothesized (significant correlations with Short Form 36 subscales, Western Ontario and McMaster Universities Osteoarthritis Index, and International Knee Documentation Committee Subjective Knee Form), and high responsiveness (standard response means = 0.97 to 1.23, standard effect size = 0.81 to 0.91). Simplified Chinese of KOS-ADLS was shown to have good reliability, validity, and responsiveness for use in patients with knee disorders in China.

To examine relationships between self-reported ankle function and Hoffmann (H) reflex modulation during changes in body positions in patients with chronic ankle instability (CAI). Observational. Laboratory. Thirty-one young adults with CAI (19 males, 12 females) participated. There were two subscales of Foot and Ankle Ability Measure (FAAM) to quantify self-reported ankle function during activities of daily living (ADL) and sports activities. Maximum H-reflexes (H-max) and motor waves (M-max) from soleus and fibularis longus were recorded while participants lied prone and stood in bipedal and unipedal stances. For each muscle, percent change scores in Hmax:Mmax ratios were calculated between each pair of positions: prone-to-bipedal, bipedal-to-unipedal, and prone-to-unipedal, and used as a measure of H-reflex modulation. Pearson correlation coefficients were calculated between FAAM and H-reflex modulation measures. There were significant correlations between: (1) FAAM-ADL and soleus prone-to-unipedal modulation (r = 0.384, p = 0.04), (2) FAAM-Sport and soleus prone-to-unipedal modulation (r = 0.505, p = 0.005), (3) FAAM-Sport and fibular bipedal-to-unipedal modulation (r = 0.377, p = 0.05), and (4) FAAM-Sport and fibular prone-to-unipedal modulation (r = 0.396, p = 0.04). CAI patients presented moderate, positive relationships between self-reported ankle function and H-reflex modulation during changes in body positions. Copyright © 2015 Elsevier Ltd.

To examine whether activity restriction specifically induced by fear of falling (FF) contributes to greater risk of disability and decline in physical function. Prospective cohort study. Population-based older cohort. Six hundred seventy-three community-living elderly (> or = 65) participants in the Invecchiare in Chianti Study who reported FF. FF, fear-induced activity restriction, cognition, depressive symptoms, comorbidities, smoking history, and demographic factors were assessed at baseline. Disability in activities of daily living (ADLs) and instrumental activities of daily living (IADLs) and performance on the Short Performance Physical Battery (SPPB) were evaluated at baseline and at the 3-year follow-up. One-quarter (25.5%) of participants did not report any activity restriction, 59.6% reported moderate activity restriction (restriction or avoidance of < 3 activities), and 14.9% reported severe activity restriction (restriction or avoidance of > or = 3 activities). The severe restriction group reported significantly higher IADL disability and worse SPPB scores than the no restriction and moderate restriction groups. Severe activity restriction was a significant independent predictor of worsening ADL disability and accelerated decline in lower extremity performance on SPPB over the 3-year follow-up. Severe and moderate activity restriction were independent predictors of worsening IADL disability. Results were consistent even after adjusting for multiple potential confounders. In an elderly population, activity restriction associated with FF is an independent predictor of decline in physical function. Future intervention studies in geriatric preventive care should directly address risk factors associated with FF and activity restriction to substantiate long-term effects on physical abilities and autonomy of older persons.

We assessed whether cognitive and functional decline in community-dwelling patients with mild Alzheimer disease (AD) dementia were associated with increased societal costs and caregiver burden and time outcomes. Cognitive decline was defined as a ≥3-point reduction in the Mini-Mental State Examination and functional decline as a decrease in the ability to perform one or more basic items of the Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory (ADCS-ADL) or ≥20% of instrumental ADL items. Total societal costs were estimated from resource use and caregiver hours using 2010 costs. Caregiver burden was assessed using the Zarit Burden Interview (ZBI); caregiver supervision and total hours were collected. Of 566 patients with mild AD enrolled in the GERAS study, 494 were suitable for the current analysis. Mean monthly total societal costs were greater for patients showing functional (+61%) or cognitive decline (+27%) compared with those without decline. In relation to a typical mean monthly cost of approximately EUR 1,400 at baseline, this translated into increases over 18 months to EUR 2,254 and 1,778 for patients with functional and cognitive decline, respectively. The number of patients requiring supervision doubled among patients showing functional or cognitive decline compared with those not showing decline, while caregiver total time increased by 70 and 33%, respectively and ZBI total score by 5.3 and 3.4 points, respectively. Cognitive and, more notably, functional decline were associated with increases in costs and caregiver outcomes in patients with mild AD dementia.

Insights about Fall Prevention of Older Adults in the State of Hawai'i.

The senior population in Hawai'i is growing at a dramatic pace. In the older population, falls and fall-related injuries are leading causes of morbidity and mortality. Moreover, the health care costs for falls are very high. The State of Hawai'i has taken measures to prevent falls through the promotion of medication reviews, vision checks, home assessments, and exercise. However, current published examinations of fall preventive measures have been insufficient, and more research is needed to confirm risk factors, effectiveness of preventive measures, and to explore future objectives. This paper examined the validity of fall risk factors and fall preventive measures for Hawai'i's seniors by conducting mail questionnaire surveys to a sample of seniors using medical alert services from one company in Hawai'i. The results of chi-square analysis suggest that having reduced ability to perform Activities of Daily Living (ADL) and reduced Instrumental Activities of Daily Living (IADL) were associated with a greater risk of falls ( P < .01). In addition, those who fell were more likely to talk about fall preventions with their family members or friends and health providers compared with those who did not ( P = .048 and .003, respectively). Evidence-based exercise programs for strengthening muscles and controlling physical balance may be needed to improve ADL and IADL. Furthermore, the results suggest that seniors do not accept that they are at risk of falling before they actually fall. Public health providers should consider how they approach seniors, and how they inform them of the importance of fall prevention across the life span.

This study compared the functional ability and perceived health status of stroke patients treated by a domiciliary rehabilitation team or by routine hospital-based services after discharge from hospital. Patients discharged from two acute and three rehabilitation hospitals in Nottingham were randomly allocated in three strata (Health Care of the Elderly, General Medical and Stroke Unit) to receive domiciliary or hospital-based care after discharge. Functional recovery was assessed by the Extended Activities of Daily Living (ADL) scale three and six months after discharge and perceived health at six months was measured by the Nottingham Health Profile. A total of 327 eligible patients of 1119 on a register of acute stroke admissions were recruited over 16 months. Overall there were no differences between the groups in their Extended ADL scores at three or six months, or their Nottingham Health Profile scores at six months. In the Stroke Unit stratum, patients treated by the domiciliary team had higher household (p = 0.02) and leisure activity (p = 0.04) scores at six months than those receiving routine care. In the Health Care of the Elderly stratum, death or a move into long-term institutional care at six months occurred less frequently in patients allocated to the routine service, about half of whom attended a geriatric day hospital. Overall there was no difference in the effectiveness of the domiciliary and hospital-based services, although younger stroke unit patients appeared to do better with home therapy while some frail elderly patients might have benefited from day hospital attendance.

Stroke is a disabling disease. In elderly populations, stroke is the third leading cause of death and the primary cause of reduction in or loss of functional ability and personal autonomy. Possible associations between levels of total serum cholesterol (TC) and both incidence of stroke and functional outcomes after rehabilitation are still under study. To detect positive and negative prognostic factors associated with functional outcomes in first-time stroke patients admitted to an integrated home care rehabilitative program. This study enrolled 141 patients with a first-time stroke who were admitted to a home care rehabilitation program. Primary outcome measures were the Barthel activities of daily living (ADL) and mobility indices at the beginning and end of the rehabilitative treatment. The impact of TC and other demographic and clinical variables was analyzed using bivariate and multivariate logistic regression analyses. Age and Short Portable Mental Status Questionnaire (SPMSQ) score were negatively associated with functional outcome. In contrast, elevated TC was positively associated with a better home rehabilitative treatment outcome. Barthel index score at admission was negatively associated with outcomes assessed by the Barthel ADL index and age with outcomes assessed by the Barthel mobility index. In a multivariate logistic regression analysis, SPMSQ score and elevated TC were significantly associated with outcome. Specifically, higher SPMSQ scores were negatively associated with better rehabilitative treatment outcomes, whereas elevated TC was positively associated. Elevated TC seems to be associated with better functional outcomes in patients with first-time stroke. Copyright © 2012 Elsevier Inc. All rights reserved.

Laboratory crushing experiments were conducted on a range of low- to high-volatile bituminous coals to investigate the various factors influencing airborne respirable dust (ARD) generation. This research was conducted to identify the principles of ARD liberation from the coal product. Five U.S. bituminous coals were uniformly prepared and processed through a double roll crusher located in a low-velocity wind tunnel. Experimental factors studied included inherent coal seam constituents, coal grindability, specific energy of crushing, product size characteristics, dust cloud electrostatic field, and specific ARD generated. The results of this investigation indicate that a combination of several factors are associated withmore » ARD generation. One factor is the effect of coal rank, described by the inherent moist fuel ratio, on the product size characteristics, defined by Schuhmann size function parameters. Another key factor is the effect of air dry loss (ADL) moisture in the coal seam on the breakage-induced electrostatic field of airborne dust. The effect of these factors is that different percentages of <10-micrometers coal particles are dispersed as ARD. A discussion of electrostatic field principles, coal ADL, and its effect on ARD generation is presented.« less

To examine whether companion animals or attachment to a companion animal was associated with changes in physical and psychological health in older people and whether the relationships between physical and psychological health and human social networks were modified by the presence or absence of a companion animal. A 1-year longitudinal study with standardized telephone interview data collected at baseline and repeated at 1-year Wellington County, Ontario, Canada An age- and sex stratified random sample (baseline n = 1054; follow-up n = 995) of noninstitutionalized adults aged 65 and older (mean age = 73, SD +/- 6.3) Social Network Activity was measured using a family and non-family social support scale, participation in an organized social group, involvement in the affairs of the social group, the practice of confiding in others, feelings of loneliness, and the perceived presence of support in a crisis situation. Chronic conditions were measured as the current number of selected health problems. Pet ownership was assessed by the report of owning a dog or a cat and the Lexington Attachment to Pets Scale score. Physical health was assessed as the ability to perform Activities of Daily Living (ADLs). Psychological health was measured as a summed score comprising the level of satisfaction regarding one's health, family and friend relationships, job, finances, life in general, overall happiness, and perceived mental health. Sociodemographic variables assessed include subject age, sex, marital status, living arrangements, education, household income, and major life events. Pet owners were younger, currently married or living with someone, and more physically active than non-pet owners. The ADL level of respondents who did not currently own pets deteriorated more on average (beta = -.270, P = .040) than that of respondents who currently owned pets after adjusting for other variables during the 1-year period. No statistically significant direct association was observed between pet ownership and change in psychological well-being (P > .100). However, pet ownership significantly modified the relationship between social support and the change in psychological well-being (P = .001) over a 1-year period. The results demonstrate the benefits of pet ownership in maintaining or slightly enhancing ADL levels of older people. However, a more complex relationship was observed between pet ownership and an older person's well-being.

Comorbidity, disability and geriatric syndromes in elderly breast cancer survivors. Results of a single-center experience.

Advancing age is a major risk factor for breast cancer. Long-term follow-up is recommended after diagnosis and treatment of early breast cancer. With older age, the risk of comorbid conditions and functional impairment increases. A useful tool in the management and follow-up of these elderly patients could be a comprehensive geriatric assessment (CGA). A descriptive, transversal study was carried out of the prevalence of other comorbidities and of the functional impairment in elderly patients on follow-up after curative treatment of early breast cancer. Women aged> or =70 at diagnosis; early breast cancer treated surgically. No disease recurrence allowed. CGA was conducted in an oncology unit using screening instruments (activities of daily living [ADL]; instrumental activities of daily living [IADL]; body mass index [BMI]; geriatric depression scale [GDS]). Cognitive status was reported by the patient. Comorbidity was classified using the Charlson score. From January 2005 to June 2006 91 patients were seen. Mean age at surgery: 76 (70-92). Mean age at CGA: 80 (71-95). Aged population (almost 25% were more than 84 at the time of CGA). Median follow-up: 5 years (range 1-12). Good performance status (PS) in most (only 9% PS 2). Eighty-three percent were fully independent for ADL and 71% for IADL. IADL most affected was the ability to drive/use public transport. Twenty-eight percent had geriatric syndromes and 23% were classified as "frail". Increased age was associated with worsening PS (p=0.0001) and worsening function (ADL p<0.0001 and IADL p<0.0001). The study is remarkable for the high comorbidity index found in the elderly survivors. Median Charlson score was 2 (1-6). More than 75% of the series had a score >/=4. Cardiovascular disease (hypertension) was the most prevalent comorbid condition. As an effect of this, the majority of patients were polymedicated (75% took more than six drugs). Comorbidity was independent of functionality and age. Older patients with early breast cancer on follow-up have a high prevalence of comorbidity. In our series, function and independence were maintained. A selection bias cannot be excluded, as the fitter patients are those who usually continue with the follow-up, while those frail patients who do not continue because of their functional impairment are usually lost.

Dementia causes semantic and episodic memory impairments that limit patients' activities of daily living (ADL) and increase caregiver burden. Spaced retrieval training uses repetitive retrieval to strengthen cognitive and motor skills intuitively in mild / moderate dementia patients who retain preserved implicit / non-declarative memory. This article describes and discusses the operative mechanism, influencing variables, and practical applications of spaced retrieval training. We hope this article increases professional understanding and application of this training approach to improve dementia patient ADL and improve quality of life for both caregivers and patients.

A decline in cognitive ability commonly occurs among older individuals. This study sought to explore the restorative effects of exercise in older patients with existing cognitive disabilities. Ninety-six patients with mild cognitive impairment were placed in an exercise program for six months. Following completion of the program, participants were assessed via the Chinese Mini Mental Status Examination (MMSE), Activity of Daily Living (ADL) assessment, and body movement testing and compared to a control group of patients with mild cognitive impairment who did not participate in the exercise program (N = 102). Statistical analyses were performed using the Student’s t-test and chi-square test to compare results between groups. Compared with control group, patients who exercised showed improved cognitive function in immediate memory (p < 0.001) and delayed recall (p = 0.004) function. In addition, activities associated with daily living showed improvement (p < 0.001), as did body movement (p < 0.05), arm stability (p < 0.001), and the appearance of rotation (p < 0.05). Based on these results, we conclude that participation in an exercise program can improve patients’ cognitive function, physical abilities, and body movement capacity. PMID:25419345

Costs of care in a mild-to-moderate Alzheimer clinical trial sample: key resources and their determinants.

PubMed

Gustavsson, Anders; Cattelin, Francoise; Jönsson, Linus

2011-07-01

Costs of care are frequently included as secondary endpoint in Alzheimer clinical trials because payers demand evidence of the budgetary effects of novel therapies. Future clinical trial protocols can be optimized on the basis of the currently available data, including what are the key resources and how are they correlated to disease severity measures. Primary patient-level data from two 18 months clinical trials of a putative disease modifier in mild-to-moderate Alzheimer's disease (n = 2,744) were analyzed to identify key components of costs of care and their determinants in a clinical trial setting. Costs of care were assessed with the resource utilization in dementia Lite (RUD) instrument, which includes patient accommodation, informal care, community care, and hospitalizations. The contribution of each component to total costs of care and their correlation with one another and key disease severity measures (Alzheimer's Disease Assessment Scale--Cognitive Subscale, Mini-Mental State Examination, Clinical Dementia Rating-Sum of Boxes, Alzheimer's Disease Cooperative Study--Activities of Daily Living Inventory, and Neuropsychiatric Inventory Questionnaire) was explored. Informal care constituted 82% to 86% of the total costs of care over the 18-months trial and community care services and patient accommodation contributed 6% to 8% each. Informal care was positively correlated with hospitalizations but negatively to patient accommodation, indicating that these services are supplements. Informal care also had the strongest pair-wise correlation with key disease severity measures, suggesting a higher chance of identifying a treatment effect on this component. ADL-ability (Alzheimer's Disease Cooperative Study--Activities of Daily Living Inventory) was the strongest predictor of costs of care of all disease severity measures. Informal care is the most important component of costs of care in a mild-to-moderate Alzheimer clinical trial sample, and it is primarily driven by the ADL-ability of the patient. Investigators should focus on the assessment of this economic endpoint because a significant treatment effect on this resource is likely to also affect total costs of care.

To examine the effects of intranasal insulin administration on cognition, function, cerebral glucose metabolism, and cerebrospinal fluid biomarkers in adults with amnestic mild cognitive impairment or Alzheimer disease (AD). Randomized, double-blind, placebo-controlled trial. Clinical research unit of a Veterans Affairs medical center. The intent-to-treat sample consisted of 104 adults with amnestic mild cognitive impairment (n = 64) or mild to moderate AD (n = 40). Intervention  Participants received placebo (n = 30), 20 IU of insulin (n = 36), or 40 IU of insulin (n = 38) for 4 months, administered with a nasal drug delivery device (Kurve Technology, Bothell, Washington). Primary measures consisted of delayed story recall score and the Dementia Severity Rating Scale score, and secondary measures included the Alzheimer Disease's Assessment Scale-cognitive subscale (ADAS-cog) score and the Alzheimer's Disease Cooperative Study-activities of daily living (ADCS-ADL) scale. A subset of participants underwent lumbar puncture (n = 23) and positron emission tomography with fludeoxyglucose F 18 (n = 40) before and after treatment. Outcome measures were analyzed using repeated-measures analysis of covariance. Treatment with 20 IU of insulin improved delayed memory (P < .05), and both doses of insulin (20 and 40 IU) preserved caregiver-rated functional ability (P < .01). Both insulin doses also preserved general cognition as assessed by the ADAS-cog score for younger participants and functional abilities as assessed by the ADCS-ADL scale for adults with AD (P < .05). Cerebrospinal fluid biomarkers did not change for insulin-treated participants as a group, but, in exploratory analyses, changes in memory and function were associated with changes in the Aβ42 level and in the tau protein-to-Aβ42 ratio in cerebrospinal fluid. Placebo-assigned participants showed decreased fludeoxyglucose F 18 uptake in the parietotemporal, frontal, precuneus, and cuneus regions and insulin-minimized progression. No treatment-related severe adverse events occurred. These results support longer trials of intranasal insulin therapy for patients with amnestic mild cognitive impairment and patients with AD.

Stroke is one of the most common causes of acquired disability, leaving numerous adults with cognitive and motor impairments, and affecting patients' capability to live independently. There is substancial evidence on post-stroke cognitive rehabilitation benefits, but its implementation is generally limited by the use of paper-and-pencil methods, insufficient personalization, and suboptimal intensity. Virtual reality tools have shown potential for improving cognitive rehabilitation by supporting carefully personalized, ecologically valid tasks through accessible technologies. Notwithstanding important progress in VR-based cognitive rehabilitation systems, specially with Activities of Daily Living (ADL's) simulations, there is still a need of more clinical trials for its validation. In this work we present a one-month randomized controlled trial with 18 stroke in and outpatients from two rehabilitation units: 9 performing a VR-based intervention and 9 performing conventional rehabilitation. The VR-based intervention involved a virtual simulation of a city - Reh@City - where memory, attention, visuo-spatial abilities and executive functions tasks are integrated in the performance of several daily routines. The intervention had levels of difficulty progression through a method of fading cues. There was a pre and post-intervention assessment in both groups with the Addenbrooke Cognitive Examination (primary outcome) and the Trail Making Test A and B, Picture Arrangement from WAIS III and Stroke Impact Scale 3.0 (secondary outcomes). A within groups analysis revealed significant improvements in global cognitive functioning, attention, memory, visuo-spatial abilities, executive functions, emotion and overall recovery in the VR group. The control group only improved in self-reported memory and social participation. A between groups analysis, showed significantly greater improvements in global cognitive functioning, attention and executive functions when comparing VR to conventional therapy. Our results suggest that cognitive rehabilitation through the Reh@City, an ecologically valid VR system for the training of ADL's, has more impact than conventional methods. This trial was not registered because it is a small sample study that evaluates the clinical validity of a prototype virtual reality system.

Mobility characteristics associated with activity of daily living such as sitting down, lying down, rising up, and walking are considered to be important in maintaining functional independence and healthy life style especially for the growing elderly population. Characteristics of postural transitions such as sit-to-stand are widely used by clinicians as a physical indicator of health, and walking is used as an important mobility assessment tool. Many tools have been developed to assist in the assessment of functional levels and to detect a person’s activities during daily life. These include questionnaires, observation, diaries, kinetic and kinematic systems, and validated functional tests. These measures are costly and time consuming, rely on subjective patient recall and may not accurately reflect functional ability in the patient’s home. In order to provide a low-cost, objective assessment of functional ability, inertial measurement unit (IMU) using MEMS technology has been employed to ascertain ADLs. These measures facilitate long-term monitoring of activity of daily living using wearable sensors. IMU system are desirable in monitoring human postures since they respond to both frequency and the intensity of movements and measure both dc (gravitational acceleration vector) and ac (acceleration due to body movement) components at a low cost. This has enabled the development of a small, lightweight, portable system that can be worn by a free-living subject without motion impediment – TEMPO (Technology Enabled Medical Precision Observation). Using this IMU system, we acquired indirect measures of biomechanical variables that can be used as an assessment of individual mobility characteristics with accuracy and recognition rates that are comparable to the modern motion capture systems. In this study, five subjects performed various ADLs and mobility measures such as posture transitions and gait characteristics were obtained. We developed postural event detection and classification algorithm using denoised signals from single wireless IMU placed at sternum. The algorithm was further validated and verified with motion capture system in laboratory environment. Wavelet denoising highlighted postural events and transition durations that further provided clinical information on postural control and motor coordination. The presented method can be applied in real life ambulatory monitoring approaches for assessing condition of elderly.

Geriatric stroke patients are generally frail, have an advanced age and co-morbidity. It is yet unclear whether specific groups of patients might benefit differently from structured multidisciplinary rehabilitation programs. Therefore, the aims of our study are 1) to determine relevant patient characteristics to distinguish groups of patients based on their admission scores in skilled nursing facilities (SNFs), and (2) to study the course of these particular patient-groups in relation to their discharge destination. This is a longitudinal, multicenter, observational study. We collected data on patient characteristics, balance, walking ability, arm function, co-morbidity, activities of daily living (ADL), neuropsychiatric symptoms, and depressive complaints of 127 geriatric stroke patients admitted to skilled nursing facilities with specific units for geriatric rehabilitation after stroke. Cluster analyses revealed two groups: cluster 1 included patients in poor condition upon admission (n = 52), and cluster 2 included patients in fair/good condition upon admission (n = 75). Patients in both groups improved in balance, walking abilities, and arm function. Patients in cluster 1 also improved in ADL. Depressive complaints decreased significantly in patients in cluster 1 who were discharged to an independent- or assisted-living situation. Compared to 80% of the patients in cluster 2, a lower proportion (46%) of the patients in cluster 1 were discharged to an independent- or assisted-living situation. Stroke patients referred for rehabilitation to SNFs could be clustered on the basis of their condition upon admission. Although patients in poor condition on admission were more likely to be referred to a facility for long-term care, this was certainly not the case in all patients. Almost half of them could be discharged to an independent or assisted living situation, which implied that also in patients in poor condition on admission, discharge to an independent or assisted living situation was an attainable goal. It is important to put substantial effort into the rehabilitation of patients in poor condition at admission.

Falls among elderly are a major public health issue in Sweden. The aim was to determine whether nursing assistants can prevent falls by supervising community-living elderly individuals with a history of falling in performing individually designed home exercise programmes. A randomised controlled trial was performed in Sweden, in eight municipalities in the county of Örebro, during 2007-2009. Community-living persons 65 years or older having experienced at least one fall during the last 12 months were included. The intervention group consisted of 76 participants, and there were 72 in the control group. The interventions were free of charge and were shared between a physiotherapist and a nursing assistant. The former designed a programme aiming to improve balance, leg strength and walking ability. The nursing assistant supervised the performance of activities during eight home visits during a 5-month intervention period. The measures and instruments used were health-related quality of life (SF-36), activity of daily living (ADL-staircase), balance, (Falls Efficacy Scale, and Berg Balance Scale), walking ability (Timed Up and Go and the 3-metre walking test), leg strength, (chair stand test). All participants were asked to keep a structured calendar of their physical exercise, walks and occurrence of falls during their 12-month study period. Hospital healthcare consumption data were collected. Although the 5-month intervention did not significantly decrease the risk for days with falls, RR 1.10 (95% CI 0.58, 2.07), p = 0.77, significant changes in favour of the intervention group were noted for balance (p = 0.03), ADL (p = 0.035), bodily pain (p = 0.003) and reported health transition over time (p = 0.008) as well as less hospital care due to fractures (p = 0.025). Additional studies with more participants are needed to establish whether or not falls can be significantly prevented with this model which is workable in home-based fall prevention. © 2017 Nordic College of Caring Science.

The applicability and validity of many patient-reported outcome measures in the high-functioning population are not well understood. To compare the psychometric properties of the modified Harris Hip Score (mHHS), the Hip Outcome Score activities of daily living subscale (HOS-ADL) and sports (HOS-sports), and the Lower Extremity Computerized Adaptive Test (LE CAT). The hypotheses was that all instruments would perform well but that the LE CAT would show superiority psychometrically because a combination of CAT and a large item bank allows for a high degree of measurement precision. Cohort study (diagnosis); Level of evidence, 2. Data were collected from 472 advanced-age, active participants from the Huntsman World Senior Games in 2012. Validity evidences were examined through item fit, dimensionality, monotonicity, local independence, differential item functioning, person raw score to measure correlation, and instrument coverage (ie, ceiling and floor effects), and reliability evidences were examined through Cronbach alpha and person separation index. All instruments demonstrated good item fit, unidimensionality, monotonicity, local independence, and person raw score to measure correlations. The HOS-ADL had high ceiling effects of 36.02%, and the mHHS had ceiling effects of 27.54%. The LE CAT had ceiling effects of 8.47%, and the HOS-sports had no ceiling effects. None of the instruments had any floor effects. The mHHS had a very low Cronbach alpha of 0.41 and an extremely low person separation index of 0.08. Reliabilities for the LE CAT were excellent and for the HOS-ADL and HOS-sports were good. The LE CAT showed better psychometric properties overall than the HOS-ADL, HOS-sports, and mHHS for the senior population. The mHHS demonstrated pronounced ceiling effects and poor reliabilities that should be of concern. The high ceiling effects for the HOS-ADL were also of concern. The LE CAT was superior in all psychometric aspects examined in this study. Future research should investigate the LE CAT for wider use in different populations.

This study was performed to determine the levels of quality of life (QOL) according to the grade of long-term care service for the elderly people who were admitted from long-term care insurance, and to reveal its association with the physical and mental functioning such as the Activity of Daily Living (ADL), the Instrumental Activity of Daily Living (IADL), the Center for Epidemiologic Studies Depression Scale (CES-D), and the Mini-Mental State Examination-Korean version (MMSE-K). The interviews were performed during the period from March 1 to May 31, 2009, for 958 elderly people in urban and rural areas. The questionnaire items included various indices such as the ADL, IADL, CES-D, and MMSE-K, as independent variables and the index of QOL, as the dependent ones. For statistical analysis, t-tests were used for the mean scores of QOL according to gender and the grade of long-term care services, and Spearman's correlation was used for each variable. The effects of physical and mental functioning for QOL were assessed by covariance structure analysis. The statistical significance was set at p<0.05. The mean scores of QOL among all the subjects was 55.4 ± 15.62 (Grade I: 49.7 ± 14.17, Grade II: 56.8 ± 14.62, Grade III: 59.4 ± 16.36), and it was lower according to the higher grade of long-term care insurance. In terms of the correlation matrix of the QOL and the physical and mental function factors, the QOL showed positive correlation with the ADL, IADL and MMSE-K, while it had negative correlation with depression. On the analysis of covariance, mental functioning (depression and the MMSE-K) had a greater influence on the level of QOL than the physical functioning (ADL and IADL). The level of the QOL in the elderly people who were admitted from long-term care insurance was lower according to higher the grade of long-term care insurance. Also, the mental functioning (depression and MMSE-K) was more influential on the level of the QOL than the physical functioning (ADL and IADL).

To present the study design and baseline results of the longitudinal International Mobility in Aging Study (IMIAS) on gender differences in physical performance and mobility disability prevalence in five diverse societies. Data are from surveys on random samples of people aged 65-74 years at Canadian (Kingston, Ontario; Saint-Hyacinthe, Quebec), Mediterranean (Tirana, Albania) and Latin American sites (Natal, Brazil; Manizales, Colombia) (N=1995). Mobility disability was defined as reporting difficulty in walking 400m or climbing stairs. Activities of daily living (ADL) disability was based on any self-reported difficulty in five mobility-related ADLs. The short physical performance battery (SPPB) was used to assess physical performance. Poisson regression models were fitted to estimate prevalence ratios. Age-adjusted prevalence of low SPPB, mobility disability and ADL disability were higher in women than in men in all sites except for Kingston. After adjustment for education and income, gender differences in SPPB and ADL disability attenuated or disappeared in Saint-Hyacinthe and Manizales but remained large in Tirana and Natal and mobility disability remained more frequent in women than in men at all sites except Kingston. After further adjustment by chronic conditions and depressive symptoms, gender differences in mobility remained large at all sites except Kingston but only in Tirana did women have significantly poorer physical performance than men. Results provide evidence for gender as a risk factor to explain poorer physical function in women and suggest that moving toward gender equality could attenuate the gender gap in physical function in old age.

Functional loss among older adults is known to follow a hierarchical sequence, but little is known about whether such sequences differ across socio-cultural contexts. The aim of this study is to construct activities of daily livings (ADL) scales for oldest-old adults in the United States and China so as to compare their functional loss sequences. We use data from the Asset and Health Dynamics of the Oldest Old (n=1607) and Chinese Longitudinal Healthy Longevity Survey (n=5570) for years 1998-2008. ADL items are calibrated within a scale using the Rasch measurement model. Rasch scores are averaged across survey waves to identify the ADL loss sequence for each study population. We also assess scale stability over measurement periods. Factor analyses confirm that the ADL items in each study population can be combined meaningfully to form a hierarchical sequence. Internal consistency assessed by Cronbach's alpha is high (0.81 to 0.95). We find that bathing is the first activity that both older Americans and Chinese have difficulty with, while eating is the last activity. There are, however, differences in the rank order for toileting (ranked more challenging in the Chinese sample) and dressing (ranked more challenging in the U.S. sample). Item orderings are stable over time. The results highlight the relative importance of bathing in the functional loss sequence for older adults, regardless of socio-cultural context. Health interventions are needed to address deficits in the bathroom environment, especially in developing countries like China. Copyright © 2017 Elsevier B.V. All rights reserved.

Functionality, comorbidities, polypharmacy, nutritional status and sarcopenia affect the prognosis of elderly excessively. These parameters are influenced by the population, living settings and age. We aimed to study these parameters in Turkish community-dwelling male elderly. We studied 274 male elderly ≥60 years of age admitted to our Geriatrics outpatient clinics. Mean age was 74.4 ± 7.1 years; 47.4% of the subjects were ≥75 years, 24.1% were ≥80 years. Mean activities-of-daily-living (ADL) and instrumental ADL (IADL) scores were 9.4 and 11.1, respectively. Patients with at least one-dependence at ADL-IADL were 22.6%-47.2%, and more than half-dependence at ADL-IADL were 2.8%-17.9%, respectively. Mean number of comorbidities were 2.6. Most common diagnosis was hypertension with 65%; mean number of drugs were 4.5; 55.3% were using ≥4 chronic drugs. Prevalences of malnutrition were 3.7%-6.9%, malnutrition risk were 23.5%-26.7% by the mini nutritional assessment test-long form and short form, respectively. Calf circumference was measured <31 cm in 10.5%. Our findings suggest that Turkish community-dwelling male elderly may have greater prevalences of functional dependence, sarcopenia but lower rates of malnutrition and similar rates of polypharmacy compared with the western developing countries and developed countries. This study emphasized the geographical differences in and/or between the individual countries highlighting the need for studies both country- and world-wide.

To assess the effects of preadmission functional impairment on Medicare costs of postacute care up to 365 days after hospital discharge. Longitudinal cohort study. Health and Retirement Study (HRS). Nationally representative sample of 16,673 Medicare hospitalizations of 8,559 community-dwelling older adults from 2000 to 2012. The main outcome was total Medicare costs in the year after hospital discharge, assessed according to Medicare claims data. The main predictor was functional impairment (level of difficulty or dependence in activities of daily living (ADLs)), determined from HRS interview preceding hospitalization. Multivariable linear regression was performed, adjusted for age, race, sex, income, net worth, and comorbidities, with clustering at the individual level to characterize the association between functional impairment and costs of postacute care. Unadjusted mean Medicare costs for 1 year after discharge increased with severity of impairment in a dose-response fashion (P < .001 for trend); 68% had no functional impairment ($25,931), 17% had difficulty with one ADL ($32,501), 7% had dependency in one ADL ($39,928), and 8% had dependency in two or more ADLs ($45,895). The most severely impaired participants cost 77% more than those with no impairment; adjusted analyses showed attenuated effect size (33% more) but no change in trend. Considering costs attributable to comorbidities, only three conditions were more expensive than severe functional impairment (lymphoma, metastatic cancer, paralysis). Functional impairment is associated with greater Medicare costs for postacute care and may be an unmeasured but important marker of long-term costs that cuts across conditions. © 2017, Copyright the Authors Journal compilation © 2017, The American Geriatrics Society.

Recent studies suggest that combined non-pharmacological interventions are more beneficial than single interventions for primary and secondary prevention of dementia. We previously reported enhanced effects of physical exercise with music (ExM) on cognitive function in normal elderly people compared to exercise alone. To identify if ExM improves cognitive function and activities of daily livings (ADLs) in dementia patients over cognitive stimulation (CS). We enrolled 85 patients with mild to moderate dementia. Forty-three subjects performed ExM developed by the Yamaha Music Foundation, and 42 subjects performed cognitive stimulation using portable game consoles and drills involving easy calculations, mazes, and mistake-searching in pictures. Interventions were performed once a week for 40 minutes. Before and after the six-month intervention, patients were assessed using neuropsychological batteries, and ADLs were assessed by patients' caregivers using the functional independence measure (FIM). Voxel-based specific regional analysis system for Alzheimer's disease (VSRAD) was used to assess medial temporal lobe atrophy. Twenty-three subjects dropped out during the intervention. Thirty-one patients from each group were analyzed. Post-intervention, both groups showed significantly improved visuospatial function. Significant benefits were observed in psychomotor speed or memory in the ExM or CS groups, respectively. FIM scores, reflecting ADLs, and VSRAD scores were significantly preserved in the ExM group, but significantly worsened in the CS group. ExM produced greater positive effects on cognitive function and ADLs in patients with mild to moderate dementia than CS, excluding memory. Optimal interventions for dementia will likely be achieved by combining ExMand CS.

Country differences in resource use and costs of Alzheimer's disease (AD) may be driven by differences in health care systems and resource availability. To compare country resource utilization drivers of societal costs for AD dementia over 18 months. GERAS is an observational study in France (n = 419), Germany (n = 550), and the UK (n = 526). Resource use of AD patients and caregivers contributing to >1% of total societal costs (year 2010) was assessed for country differences, adjusting for participant characteristics. Mean 18-month societal costs per patient were France €33,339, Germany €38,197, and UK €37,899 (£32,501). Caregiver time spent on basic and instrumental activities of daily living (ADL) contributed the most to societal costs (54% France, 64% Germany, 65% UK). Caregivers in France spent less time on ADL than UK caregivers and missed fewer work days than in other countries. Compared with other countries, patients in France used more community care services overall and were more likely to use home aid. Patients in Germany were least likely to use temporary accommodation or to be institutionalized at 18 months. UK caregivers spent the most time on instrumental ADL, UK patients used fewest outpatient resources, and UK patients/caregivers were most likely to receive financial support. Caregiver time on ADL contributed the most to societal costs and differed across countries, possibly due to use of community care services and institutionalization. Other resources had different patterns of use across countries, reflecting country-specific health and social care systems.

Purpose To examine the association between waist circumference (WC) and body mass index (BMI) on disability among older adults from Latin America and the Caribbean. Methods Cross-sectional, multicenter city study of 5,786 subjects aged 65 years and older from the Health, Well-Being and Aging in Latin America and the Caribbean Study (SABE) (1999-2000). Sociodemographic variables, smoking status, medical conditions, BMI, WC, and activities of daily living (ADL) were obtained. Results Prevalence of high WC (>88 cm) in women ranged from 48.5% (Havana) to 72.7% (Mexico City), while among men (>102 cm) it ranged from 12.5% (Bridgetown) to 32.5% (Santiago). The associations between WC and ADL disability were “J” shaped, with higher risks of ADL disability observed above 110 cm for women in Bridgetown, Santiago, Havana, and Montevideo. The association in Sao Paulo is plateau with higher risk above 100 cm, and the association in Mexico City is closer to linear. Among men the associations were “U” (Bridgetown, Sao Paulo, and Havana), “J” shaped (Montevideo), plateau (Santiago), and closer to linear in Mexico City (Figure 3). When WC and BMI were analyzed together, we found that participants from Sao Paolo, Santiago, Havana, and Montevideo in the overweight or obese category with high WC were significantly more likely to report ADL disability after adjusting for all covariates. Conclusion The findings of this study suggests that both general and abdominal adiposity are associated with disability and support the use of WC in addition to BMI to assess risk of disability in older adults.

Objective To evaluate changes in activity of daily living before and after provision of electric-powered indoor/outdoor chair (EPIOC), discuss problems of current activities of daily living (ADL) evaluating tools for EPIOC users, and provide preliminary data to develop ADL evaluation tool for EPIOC user. Methods A total of 70 users who were prescribed EPIOC and had been using for more than 1 year were recruited in this study. Before and after provision of EPIOC, MBI and FIM scores were measured and a questionnaire consisting of six categories (general socioeconomic states, currently using state, whether EPIOC was helpful for social participation and occupational chances, psychiatric influences, self-reported degrees of independency, and barriers of using EPIOC) was used. Results No difference in MBI scores before and after provision of EPIOC was observed. However, the wheelchair ambulation category showed a significant difference. While motor FIM was not significantly different from MBI, FIM score were significantly (p<0.05) higher than MBI. For questions regarding social participation frequency, helpfulness of EPIOC on confidence, refreshing patients' emotions and self-reported degrees of independence, all of them showed positive responses. Especially, EPIOC users' self-reported degree of independency showed favorable results. There was discrepancy in MBI or FIM measured by physicians. Conclusion Our study showed that there was a gap between the existing ADL evaluation tool and the ADL level that EPIOC users were actually feeling. Thus, it is necessary to develop an evaluation tool specifically for EPIOC. PMID:25932425

Patients who undergo hemodialysis encounter challenges including role changes, physical degeneration, and difficulty in performing activities of daily living (ADLs) and self-care. These challenges deteriorate their physiological and psychosocial conditions, resulting in depression. High resilience (RES) and social support can alleviate stress and depression. This study evaluated the importance of RES and social support in managing depression in elderly patients undergoing maintenance hemodialysis (HD). In this descriptive, correlational study, 194 older patients undergoing HD were enrolled from the HD centers of three hospitals in northern Taiwan. The Barthel ADL Index, RES scale, Inventory of Socially Supportive Behavior, and Beck Depression Inventory-II were used. Hierarchical regression analysis was applied to evaluate the interaction of RES and social support with illness severity, demographics, and ADLs. Of the total participants, 45.9% experienced depressive symptoms. Demographic analysis showed that men and those with high educational level and income and financial independence had less depression ( p <0.01). Patients with a higher Barthel Index (n=103), RES scale (n=33), and social support (n=113) showed less depressive symptoms ( p <0.01). We found a significant negative correlation between depressive symptoms and social support ( r =-0.506, p <0.01) and RES ( r =-0.743, p <0.01). Hierarchical regression analysis showed that RES could buffer the effects of symptom severity on depression ( b =-0.436, p <0.01), but social support did not exert a buffering effect. The severity of illness symptoms and ADLs were the major determinants of depressive symptoms. High RES could alleviate depressive symptoms in the older patients undergoing HD.

This study aims to test whether persistent pain quality is associated with incident or worsening disability in four domains: mobility, ADL and IADL difficulty and physical performance. From the MOBILIZE Boston Study, a population-based cohort of adults aged ≥70 years, we studied participants with chronic pain who endorsed at least one pain quality descriptor (N=398) and completed baseline and 18-month assessments. Pain quality was assessed using an adapted short-form McGill Pain Questionnaire with 20 pain quality descriptors in 3 categories: sensory, cognitive/affective, neuropathic. Persistence was defined as endorsing the same category at baseline and 18 months. Self-reported outcomes included mobility, ADL, and IADL difficulty. Physical performance was assessed using the Short Physical Performance Battery. After adjusting for baseline pain severity and other covariates, individuals with 3 persistent categories had a greater risk of developing new or worsening IADL difficulty relative to those with 1 persistent category (RR 2.69, 95% CI 1.34, 7.79). Similar results were observed for ADL difficulty (RR 5.83, 95% CI 1.32, 25.85) but no differences were noted in risk for mobility difficulty. There was no significant linear trend in physical performance over 18 months according to number of persistent categories (p=0.68). Elders with persistent pain quality experienced a higher risk of developing new or worsening IADL and ADL disability with each additional category but not mobility difficulty or poorer physical performance. Longitudinal assessment of pain quality could be useful in determining risk for global disability among elders with chronic pain.

(1) To assess a robotic device (Handexos) during the design process with regard to usability, end user satisfaction and safety, (2) to determine whether Handexos can improve the activities of daily living (ADLs) of spinal cord injury (SCI) patients and stroke patients with upper-limb dysfunction. During a 2-year development stage of the device, a total of 37 participants (aged 22-68), 28 clinicians (experts) and nine patients with SCI or stroke (end users) were included in a user-centered design process featuring usability tests. They performed five grasps wearing the device. The assessments were obtained at the end of the session by filling out a questionnaire and making suggestions. The experts' opinion was that the modified device was an improvement over the preliminary version, although this was not reflected in the scores. Whereas end user scores for comfort, grasp, performance and safety were above the sufficiency threshold, the scores for year 2 were lower than those for year 1. The findings demonstrate that although Handexos meets the initial functional requirements and underlines the potential for assisting SCI and post-stroke subjects in ADLs, several aspects such as mechanical complexity and low adaptability to different hand sizes need to be further addressed. Implications for Rehabilitation Wearable robotics devices could improve the activities of daily living in patients with spinal cord injury or stroke. They could be a tool for rehabilitation of the upper limb. Further usability tests to improve this type of tools are recommended.

2011-02-01

Patients with Lewy body dementia (LBD) may present a unique set of symptoms and challenges to family caregivers compared with other types of dementia. Prominent difficulties include motor impairment, activities of daily living (ADLs) disability, recurrent behavioral and emotional problems (BEPs), and diagnostic difficulties. These problems are likely to affect caregivers' subjective burden. The present study used data from an Internet survey conducted by the Lewy Body Dementia Association. Respondents were 611 people who indicated that they were currently involved in the care of their relative with LBD. Subjective burden was assessed with a 12-item short version of the Zarit Burden Interview. A factor analysis revealed 3 dimensions of burden: role strain, personal strain, and worry about performance. Multiple regressions were used to examine predictors of these dimensions. BEPs, ADL disability, isolation, caregiver age, and patient gender were significant predictors of specific factors. Falls, formal service use, difficulty finding a physician, and evaluation of the physician had no significant associations with burden. These findings highlight burden experiences by caregivers of patients with LBD and the impact of BEPs, ADL assistance, and awareness about LBD on subjective burden.

Recovery of sensorimotor function and activities of daily living after cervical spinal cord injury: the influence of age.

PubMed

Wirz, Markus; Dietz, Volker

2015-02-01

This retrospective study was designed to examine the influence of age on the outcome of motor function and activities of daily living (ADLs) in patients with a cervical spinal cord injury (SCI). The study is based on the data registry of the European Multicenter Study of Spinal Cord Injury (EMSCI) study group. Initial upper-extremity motor score (UEMS) and its change over 5 months, as well as the initial Spinal Cord Independence Measure (SCIM) score, did not differ between younger adults (20-39 years) and elderly (60-79 years) patients. However, the change in SCIM score over 5 months was significantly greater in the younger patient group. Initial UEMS, SCIM, and ulnar compound motor action potentials (CMAP), reflecting peripheral nerve damage (motoneurons and roots), were significantly greater in incomplete, compared to complete, SCI, regardless of age group. The initial assessment of UEMS in combination with CMAP recordings allows an early prediction of ADLs outcomes in both younger adults and elderly subjects. The impaired translation of gain in motor score into increased ADL independence in elderly patients requires specifically tailored rehabilitation programs.

[Purpose] This study examined the quality of life (QOL) of homebound elderly hemiparetic stroke patients and factors that affect it. [Subjects] The subjects of the study were 21 homebound elderly hemiparetic stroke patients who were 65 years old or over and required care for daily living (12 males and 9 females, average age: 79.3 ± 8.4 years old). Their physical and psychological conditions, QOL, and other characteristics were researched. [Methods] The Functional Independence Measure (FIM) was used for the activities of daily living (ADL) assessment, and the MOS 36-Item Short-Form Health Survey (SF-36, Japanese version 1.2) was used for the QOL assessment. [Results] No correlations were observed between the QOL of homebound elderly hemiparetic stroke patients and their age and gender. However, the results showed that their QOL was affected by their independence in ADL, bedridden degree, and care-need level. [Conclusion] These results suggest that in order to improve the QOL of homebound elderly hemiparetic stroke patients, ongoing rehabilitation to improve independence in ADL and lower the bedridden degree and care-need level is required.

The objective of this study is to examine how increasing body mass index (BMI) among nursing home residents affects the amount of staffing assistance needed for activities of daily living (ADL). We analyzed 1,627,141 US nursing home residents reported in the 2013 Minimum Data Set in seven BMI categories, from underweight (BMI < 18.5 kg/m 2 ) to obesity Class IIIB (≥50 kg/m 2 ). Logistic regression models estimated the odds of nursing home-reported need for extensive (≥2 staff member) assistance needed for ADLs. The adjusted odds increased from 1.07 (95% Confidence Interval (95%CI) 1.06-1.08) for Class I, 1.16 (95%CI 1.14-1.17) for Class II, 1.33 (95%CI 1.31-1.35) for Class IIIA, and 1.90 (95%CI 1.86-1.95) for Class IIIB obesity residents compared to residents of normal weight. As a nursing home resident's BMI increases, especially for BMI ≥40 kg/m 2 , the need for extensive staffing assistance with ADLs also increases substantially. Copyright © 2018 Elsevier Inc.

Effectiveness of Work, Activities of Daily Living, Education, and Sleep Interventions for People With Autism Spectrum Disorder: A Systematic Review.

PubMed

Weaver, Lindy L

2015-01-01

To examine interventions addressing work, activities of daily living (ADLs), instrumental activities of daily living (IADLs), education, and sleep for people with autism spectrum disorder. A total of 23 studies were identified, and 9 work-, 11 ADL/IADL-, and 3 education-related interventions were examined. No sleep studies were identified. Use of mobile and tablet technologies for vocational skills was supported. Support for ADL/IADL intervention is variable, with indications that Cognitive Orientation to Occupational Performance, sensory integration, and contextual interventions may increase occupational performance. Preliminary evidence suggests that daily yoga and brief exercise may improve classroom performance and behavior; group physical activities may assist with school readiness variables. Evidence for using technologies for IADLs was limited, as was evidence determining effective interventions for feeding and eating issues. Studies investigating interventions related to sleep are lacking. More studies are needed in all areas, presenting opportunities for the expansion of science-driven occupational therapy practice and research for people with ASD.

Translate, transcultural adaptation and application to Brazilian Portuguese of the Alzheimer's Disease Cooperative Study - Activities of Daily Living (ADCS-ADL) scale as a cognitive screening instrument. We applied the back translation added with pretest and bilingual methods. The sample was composed by 95 elderly individuals and their caregivers. Thirty-two (32) participants were diagnosed as mild cognitive impairment (MCI) patients, 33 as Alzheimer's disease (AD) patients and 30 were considered as cognitively normal individuals. There were only little changes on the scale. The Cronbach alpha coefficient was 0.89. The scores were 72.9 for control group, followed by MCI (65.1) and by AD (55.9), with a p-value < 0.001. The ROC curve value was 0.89. We considered a cut point of 72 and we observed a sensibility of 86.2%, specificity of 70%, positive predictive value of 86.2%, negative predictive value of 70%, positive likelihood ratio of 2.9 and negative likelihood ratio of 0.2. ADCS-ADL scale presents satisfactory psychometric properties to discriminate between MCI, AD and normal cognition.

Fractures among older people are common, but there is scant evidence about the impact of fractures on functional decline in an unselected older population. The objective of this study was to analyze the impact of lower and upper body fractures on functional performance among older adults during an 8-year follow-up. A population-based cohort of 616 Finnish persons aged 65 and over was followed for up to 8 years, and the association between fractures and the risk of short-term (0-2 years) and long-term (up to 8 years) functional decline was analyzed. Fractures were categorized according their functional influence on mobility and activities of daily living (ADL) into lower and upper body fractures. Multivariate cumulative logistic regression model was used in the analyses. During the 8-year follow-up, 112 (18%) persons sustained at least one fracture. In the multivariate analyses, lower body fractures predicted both short-term and long-term decline in mobility [cumulative odds ratio (COR) 4.7, 95% confidence interval (95% CI) 1.9-11.7 and COR 2.6, 95% CI 1.1-6.2, respectively] and in ADL performance (COR 3.1, 95% CI 1.3-7.6 and COR 4.7, 95% CI 2.0-11.4, respectively). Upper body fractures predicted decline in ADL performance during the long-term follow-up (COR 2.5, 95% CI 1.3-4.8). Pre-fracture functional decline and inactivity in leisure time physical exercise were independently associated with the risk of decline in extensive activities. Fractures have an independent influence on the development of functional decline in older persons regardless of the pre-fracture health. Prevention of falls and fractures and improvement of treatment, rehabilitation and follow-up process after fractures are needed. Copyright © 2011 S. Karger AG, Basel.

Cognitive rehabilitation for executive dysfunction in adults with stroke or other adult non-progressive acquired brain damage.

2013-04-30

Executive functions are the controlling mechanisms of the brain and include the processes of planning, initiation, organisation, inhibition, problem solving, self monitoring and error correction. They are essential for goal-oriented behaviour and responding to new and novel situations. A high number of people with acquired brain injury, including around 75% of stroke survivors, will experience executive dysfunction. Executive dysfunction reduces capacity to regain independence in activities of daily living (ADL), particularly when alternative movement strategies are necessary to compensate for limb weakness. Improving executive function may lead to increased independence with ADL. There are various cognitive rehabilitation strategies for training executive function used within clinical practice and it is necessary to determine the effectiveness of these interventions. To determine the effects of cognitive rehabilitation on executive dysfunction for adults with stroke or other non-progressive acquired brain injuries. We searched the Cochrane Stroke Group Trials Register (August 2012), the Cochrane Central Register of Controlled Trials (The Cochrane Library, August 2012), MEDLINE (1950 to August 2012), EMBASE (1980 to August 2012), CINAHL (1982 to August 2012), PsycINFO (1806 to August 2012), AMED (1985 to August 2012) and 11 additional databases. We also searched reference lists and trials registers, handsearched journals and conference proceedings, and contacted experts. We included randomised trials in adults after non-progressive acquired brain injury, where the intervention was specifically targeted at improving cognition including separable executive function data (restorative interventions), where the intervention was aimed at training participants in methods to compensate for lost executive function (compensative interventions) or where the intervention involved the training in the use of an adaptive technique for improving independence with ADL (adaptive interventions). The primary outcome was global executive function and the secondary outcomes were specific components of executive function, working memory, ADL, extended ADL, quality of life and participation in vocational activities. We included studies in which the comparison intervention was no treatment, a placebo intervention (i.e. a rehabilitation intervention that should not impact on executive function), standard care or another cognitive rehabilitation intervention. Two review authors independently screened abstracts, extracted data and appraised trials. We undertook an assessment of methodological quality for allocation concealment, blinding of outcome assessors, method of dealing with missing data and other potential sources of bias. Nineteen studies (907 participants) met the inclusion criteria for this review. We included 13 studies (770 participants) in meta-analyses (417 traumatic brain injury, 304 stroke, 49 other acquired brain injury) reducing to 660 participants once non-included intervention groups were removed from three and four group studies. We were unable to obtain data from the remaining six studies. Three studies (134 participants) compared cognitive rehabilitation with sensorimotor therapy. None reported our primary outcome; data from one study was available relating to secondary outcomes including concept formation and ADL. Six studies (333 participants) compared cognitive rehabilitation with no treatment or placebo. None reported our primary outcome; data from four studies demonstrated no statistically significant effect of cognitive rehabilitation on secondary outcomes. Ten studies (448 participants) compared two different cognitive rehabilitation approaches. Two studies (82 participants) reported the primary outcome; no statistically significant effect was found. Data from eight studies demonstrated no statistically significant effect on the secondary outcomes. We explored the effect of restorative interventions (10 studies, 468 participants) and compensative interventions (four studies, 128 participants) and found no statistically significant effect compared with other interventions. We identified insufficient high-quality evidence to reach any generalised conclusions about the effect of cognitive rehabilitation on executive function, or other secondary outcome measures. Further high-quality research comparing cognitive rehabilitation with no intervention, placebo or sensorimotor interventions is recommended.

Upper limb functional electrical stimulation devices and their man-machine interfaces.

Functional Electrical Stimulation (FES) is a technique that uses electricity to activate the nerves of a muscle that is paralysed due to hemiplegia, multiple sclerosis, Parkinson's disease or spinal cord injury (SCI). FES has been widely used to restore upper limb functions in people with hemiplegia and C5-C7 tetraplegia and has improved their ability to perform their activities of daily living (ADL). At the time of writing, a detailed literature review of the existing upper limb FES devices and their man-machine interfaces (MMI) showed that only the NESS H200 was commercially available. However, the rigid arm splint doesn't fit everyone and prevents the use of a tenodesis grip. Hence, a robust and versatile upper limb FES device that can be used by a wider group of people is required.

Hip fractures (HFs) in old age frequently cause severe functional impairment and deteriorating autonomy in everyday life. Many older patients with HFs are malnourished or at risk of malnutrition. In this study, we examined the relationship between nutritional status of geriatric patients before HF and their functional and clinical course up to 6 months after hospital discharge. Observational study with follow-up after 6 months. Four wards of the department of trauma and orthopedic surgery of a large urban maximum care hospital (Klinikum Nürnberg, Nuremberg, Germany). Geriatric patients aged ≥75 years with surgically repaired proximal femoral fracture. Prefracture nutritional status was determined by Mini Nutritional Assessment (MNA). Comorbidities and complications during hospital stay were obtained from medical documentation. Functional status before HF, postoperatively, at hospital discharge, and 6 months later was assessed by Barthel Index for activities of daily living (ADL) and patients' mobility level and related to MNA categories. Associations were evaluated using χ(2), Fisher exact, Kruskal-Wallis, Mann-Whitney-U, Jonckheere-Terpstra, and Cochrane-Armitage tests as appropriate, as well as analysis of covariance with repeated measures. Of 97 included patients, 17% were malnourished and 38% at risk of malnutrition before HF. Participants with (risk of) malnutrition were equally mobile but more dependent in ADL prior to HF than well-nourished patients (P < .001). Independent of nutritional status, after 6 months 68% of participants had not regained their prefracture level of independence in ADL. According to analysis of covariance, the ADL development over time until follow-up 6 months after hospital discharge did not depend on nutritional status. However, at follow-up malnourished patients more often suffered from remaining losses in ADL ≥25% of initial Barthel Index points (P = .033) and less often had regained their prefracture mobility level (P = .020) than well-nourished patients. Clinical course did not differ significantly between the groups with different nutritional status. In this study with geriatric HF patients from all functional and cognitive levels, worse prefracture nutritional status was associated with worse functional status and more frequent remaining functional loss, whereas the trajectory of ADL recovery and clinical course did not differ significantly. Further studies with sufficient statistical power are needed to substantiate these inconclusive results. In order to clarify the association of nutritional status with functional and clinical course in geriatric patients after HF, they should preferably focus on the role of nutritional management during the hospital stay.

Stroke is the leading cause of disability. A need exists for an effective intervention to enhance upper extremity (UE) motor abilities and activities of daily living (ADL) performance. The objectives of this pilot study were to (1) determine the feasibility of adding Interactive Metronome (IM) to an occupational therapy (OT) program; and (2) determine changes in UE impairments, function, quality of life, and perceived physical performance ability and satisfaction using a combined IM + OT regimen compared with OT alone for adults with chronic stroke. This pilot study (n=10) used a 2-group (OT or IM+OT) pretest-posttest design. The intervention involved 60 minutes of IM + OT or OT alone, 3 days a week for 10 weeks. Outcome measures included the UE Fugl-Meyer (impairment), the Arm Motor Ability Test (function), the Box and Block Test (function), Stroke Impact Scale (quality of life), and the Canadian Occupational Performance Measure (perceived performance ability and satisfaction). It was feasible to add IM to OT. The IM+OT group demonstrated decreased impairment and increased quality of life. However, the OT-alone group demonstrated greater gains in function, perceived physical performance ability, and satisfaction. These findings suggest that rhythm and timing training using the IM is a feasible intervention to consider as part of therapy treatment. However, IM may fit best for prefunctional treatment, as it seemed to primarily decrease impairment. It may also serve as a supplement before or after treatment in order to maximize rehabilitation potential. Clinical implications and suggestions for future studies are provided.

While there are validated patient-reported outcomes (PRO) instruments for use in specific cancer populations, no validated general instruments exist for use in conditions common to multiple cancers, such as muscle wasting and consequent physical disability. The Medicare Current Beneficiary Survey (MCBS), a survey in a nationally representative sample of Medicare beneficiaries, includes items from three well known scales with general applicability to cancer patients: Katz activities of daily living (ADL), Rosow-Breslau instrumental ADL (IADL), and a subset of physical performance items from the Nagi scale. This study evaluated properties of the Katz ADL, Rosow-Breslau IADL, and a subset of the Nagi scale in patients with pancreatic cancer, lung cancer, and myeloproliferative neoplasms (MPN) using data from MCBS linked with Medicare claims in order to understand the potential utility of the three scales in these populations; understanding patient-perceived significance was not in scope. The study cohorts included Medicare beneficiaries aged ≥65 years as of 1 January of the year of their first cancer diagnosis with one or more health assessments in a community setting in the MCBS Access to Care data from 1991 to 2009. Beneficiaries had at least two diagnoses in de-identified Medicare claims data linked to the MCBS for one of the following cancers: pancreatic, lung, or MPN. The Katz ADL, Rosow-Breslau IADL, and Nagi scales were calculated to assess physical functioning over time from cancer diagnosis. Psychometric properties for each scale in each cohort were evaluated by testing for internal consistency, test-retest reliability, and responsiveness by comparing differences in mean scale scores over time as cancer progresses, and differences in mean scale scores before and after hospitalization (for lung cancer cohort). The study cohorts included 90 patients with pancreatic cancer, 863 with lung cancer, and 135 with MPN. Among each cancer cohort, the Katz ADL, Rosow-Breslau IADL, and Nagi scales had acceptable internal consistency (Cronbach's alpha generally between 0.70 and 0.90) and test-retest reliability for consecutive surveys before diagnosis and consecutive surveys after diagnosis (when patients' functioning was more stable). Compared with mean scale scores at the survey 1-2 years before cancer diagnosis (baseline), mean scale scores at the first survey after cancer diagnosis were significantly higher (P < 0.05), indicating worsening, for Katz ADL, Rosow-Breslau IADL, and Nagi scales (items scored 0-1) (0.54 vs. 1.45, 1.15 vs. 2.20, and 2.29 vs. 3.08, respectively, for pancreatic cancer; 0.73 vs. 1.24, 1.29 vs. 2.01, and 2.41 vs. 2.85 for lung cancer; and 0.44 vs. 0.86, 0.87 vs. 1.36, and 1.87 vs. 2.32 for MPN). Among lung cancer patients, scale scores increased significantly following a hospitalization, suggesting a worsening of functional status. The Katz ADL, Rosow-Breslau IADL, and Nagi scales collected in the MCBS demonstrate acceptable internal consistency and test-retest reliability among patients with pancreatic cancer, lung cancer, and MPN, and are consistent with clinical worsening following diagnosis or hospitalization. These results suggest that using retrospective data may allow researchers to conduct preliminary assessments of existing PRO instruments in new populations of interest and generate useful exploratory disease information before embarking on de novo PRO development.

Recognizing the factors associated with falling in Parkinson's disease (PD) would improve identification of at-risk individuals. To examine frequency of falling and baseline characteristics associated with falling in PD using the National Institute of Neurological Disorders and Stroke (NINDS) Exploratory Trials in PD Long-term Study-1 (NET-PD LS-1) dataset. The LS-1 database included 1741 early treated PD subjects (median 4year follow-up). Baseline characteristics were tested for a univariate association with post-baseline falling during the trial. Significant variables were included in a multivariable logistic regression model. A separate analysis using a negative binomial model investigated baseline factors on fall rate. 728 subjects (42%) fell during the trial, including at baseline. A baseline history of falls was the factor most associated with post-baseline falling. Men had lower odds of post-baseline falling compared to women, but for men, the probability of a post-baseline fall increased with age such that after age 70, men and women had similar odds of falling. Other baseline factors associated with a post-baseline fall and increased fall rate included the Unified PD Rating Scale (UPDRS) Activities of Daily Living (ADL) score, total functional capacity (TFC), baseline ambulatory capacity score and dopamine agonist monotherapy. Falls are common in early treated PD. The biggest risk factor for falls in PD remains a history of falling. Measures of functional ability (UPDRS ADL, TFC) and ambulatory capacity are novel clinical risk factors needing further study. A significant age by sex interaction may help to explain why age has been an inconsistent risk factor for falls in PD. Copyright © 2017 Elsevier B.V. All rights reserved.

Objectives To examine whether activity restriction specifically induced by fear of falling (FF) contributes to greater risk of disability and decline in physical function. Design Prospective cohort study. Setting Population-based older cohort. Participants Six hundred seventy-three community-living elderly (≥65) participants in the Invecchiare in Chianti Study who reported FF. Measurements FF, fear-induced activity restriction, cognition, depressive symptoms, comorbidities, smoking history, and demographic factors were assessed at baseline. Disability in activities of daily living (ADLs) and instrumental activities of daily living (IADLs) and performance on the Short Performance Physical Battery (SPPB) were evaluated at baseline and at the 3-year follow-up. Results One-quarter (25.5%) of participants did not report any activity restriction, 59.6% reported moderate activity restriction (restriction or avoidance of <3 activities), and 14.9% reported severe activity restriction (restriction or avoidance of ≥3 activities). The severe restriction group reported significantly higher IADL disability and worse SPPB scores than the no restriction and moderate restriction groups. Severe activity restriction was a significant independent predictor of worsening ADL disability and accelerated decline in lower extremity performance on SPPB over the 3-year follow-up. Severe and moderate activity restriction were independent predictors of worsening IADL disability. Results were consistent even after adjusting for multiple potential confounders. Conclusion In an elderly population, activity restriction associated with FF is an independent predictor of decline in physical function. Future intervention studies in geriatric preventive care should directly address risk factors associated with FF and activity restriction to substantiate long-term effects on physical abilities and autonomy of older persons.

Background/Aims We assessed whether cognitive and functional decline in community-dwelling patients with mild Alzheimer disease (AD) dementia were associated with increased societal costs and caregiver burden and time outcomes. Methods Cognitive decline was defined as a ≥3-point reduction in the Mini-Mental State Examination and functional decline as a decrease in the ability to perform one or more basic items of the Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory (ADCS-ADL) or ≥20% of instrumental ADL items. Total societal costs were estimated from resource use and caregiver hours using 2010 costs. Caregiver burden was assessed using the Zarit Burden Interview (ZBI); caregiver supervision and total hours were collected. Results Of 566 patients with mild AD enrolled in the GERAS study, 494 were suitable for the current analysis. Mean monthly total societal costs were greater for patients showing functional (+61%) or cognitive decline (+27%) compared with those without decline. In relation to a typical mean monthly cost of approximately EUR 1,400 at baseline, this translated into increases over 18 months to EUR 2,254 and 1,778 for patients with functional and cognitive decline, respectively. The number of patients requiring supervision doubled among patients showing functional or cognitive decline compared with those not showing decline, while caregiver total time increased by 70 and 33%, respectively and ZBI total score by 5.3 and 3.4 points, respectively. Conclusion Cognitive and, more notably, functional decline were associated with increases in costs and caregiver outcomes in patients with mild AD dementia. PMID:28611822

To determine the factors associated with impaired function in older women. Cross-sectional analysis of baseline data collected for a multicenter, prospective study of risk factors for osteoporotic fractures. Four clinical centers in Portland, Oregon, Minneapolis, Minnesota, Baltimore, Maryland, and the Monongahela Valley, Pennsylvania. A total of 9,704 ambulatory, non-black women, aged 65 years and older, recruited from population-based listings. Independent variables, including demographic and historical information (medical conditions, health habits, and medications) and physiologic measures (anthropometry, blood pressure, mental status, vision, and neuromuscular performance) were obtained from a baseline questionnaire, interview, and examination. Measurement of function was assessed by self-reported ability to perform six physical and instrumental activities of daily living (ADL) and impaired function (dependent variable) was defined as difficulty performing three or more physical and instrumental ADLs. In order of decreasing strength of association, hip fracture, osteoarthritis, parkinsonism, slower walking speed, lower hip abduction force, back pain, greater Quetelet index, osteoporosis, former alcohol use, stroke, never drinking alcohol, lower mental status, use of anxiolytics and/or sleeping medications, inability to hold the tandem position, postural dizziness, cataracts, greater waist to hip ratio, lower physical activity in the past year, greater lifetime cigarette consumption, and lower grip strength were independently associated with impaired function in multivariate analyses. Age, low educational level, diabetes, current heavy alcohol use, postural hypotension, depth perception, and contrast sensitivity were not independent predictors. A combination of neuromuscular performance measures, including decreased muscle strength and impaired balance and gait, appeared to account for the effect of age on disability. A combination of many factors, including medical conditions, health habits such as obesity, smoking, alcohol abstinence, and physical inactivity, and direct measures of neuromuscular performance are associated with impaired function in older women.

The Nursing Home Physical Performance Test (NHPPT) was developed to measure function among nursing home residents using sit-to-stand, scooping applesauce, face washing, dialing phone, putting on sweater, and ambulating tasks. Using item response theory, we explore its measurement characteristics at item level and opportunities for improvements. We used data from long-term care women. We fitted a graded response model, estimated parameters, and constructed probability and information curves. We identified items to be targeted toward lower and higher functioning persons to increase the range of abilities to which the instrument is applicable. We revised the scoring by making sit-to-stand and sweater items harder and dialing phone easier. We examined changes to concurrent validity with activities of daily living (ADL), frailty, and cognitive function. Participants were 86 years old, had more than three comorbidities, and a NHPPT of 19.4. All items had high discrimination and were targeted toward the lower middle range of performance continuum. After revision, sit-to-stand and sweater items demonstrated greater discrimination among the higher functioning and/or greater spread of thresholds for response categories. The overall test showed discrimination over a wider range of individuals. Concurrent validity correlation improved from 0.60 to 0.68 for instrumental ADL and explained variability (R2) from 22% to 36% for frailty. NHPPT has good measurement characteristics at the item level. NHPPT can be improved, implemented in computerized adaptive testing, and combined with self-report for greater utility, but a definitive study is needed. © The Author 2017.

Analysing most relevant clinical features and concordance between different functional scales in patients with advanced medical diseases (PAMD). Cross-sectional multicentre study that included PAMD (heart, lung, kidney, liver, and neurological diseases) in hospital settings from February 2009 to October 2010. We analysed clinical, biological and functional features in performing activities of daily living (ADL) by medians of Barthel Index (BI); additionally we assessed their performance status by medians of Eastern Cooperative Oncology Group-Performance Status (ECOG-PS) and Palliative Performance Scale (PPS) scores. We evaluated the concordance of these instruments in assessing functional impairment by κ and intraclass correlation coefficient tests. 1847 patients were included (average age 79 years, 50.1% men). Most common symptoms were dyspnoea (62.31%), asthenia (23%) and delirium (20.14%). Functional assessment showed a high prevalence of severe or total impairment in performing basic ADL by medians of used instruments (BI median=35 (IQR=70), and 52.1% of patients with severe-total impairment; ECOG-PS median=2 (IQR 30), and 44% of patients with severe-total impairment; and PPS median=50 (IQR 30), and 32% of patients with severe-total impairment). Concordance among these instruments was acceptably good ( κ indexes ranging from 0.653 to 0.745 (p<0.0001)). PAMD represent a population with severe functional impairment, which requires a multidisciplinary approach for proper management. Assessment of functional ability in this population by BI, ECOG-PS, and PPS showed good concordance. Published by the BMJ Publishing Group Limited.

Objectives To determine which early modifiable factors are associated with younger stroke survivors' ability to return to paid work in a cohort study with 12-months of follow-up conducted in 20 stroke units in the Stroke Services NSW clinical network. Participants Were aged >17 and <65 years, recent (within 28 days) stroke, able to speak English sufficiently to respond to study questions, and able to provide written informed consent. Participants with language or cognitive impairment were eligible to participate if their proxy provided consent and completed assessments on the participants' behalf. The main outcome measure was return to paid work during the 12 months following stroke. Results Of 441 consented participants (average age 52 years, 68% male, 83% with ischemic stroke), 218 were in paid full-time and 53 in paid part-time work immediately before their stroke, of whom 202 (75%) returned to paid part- or full-time work within 12 months. Being male, female without a prior activity restricting illness, younger, independent in activities of daily living (ADL) at 28 days after stroke, and having private health insurance was associated with return to paid work, following adjustment for other illnesses and a history of depression before stroke (C statistic 0·81). Work stress and post stroke depression showed no such independent association. Conclusions Given that independence in ADL is the strongest predictor of return to paid work within 12 months of stroke, these data reinforce the importance of reducing stroke-related disability and increasing independence for younger stroke survivors.

A survey was conducted among pharmacists providing "home-visit guidance on drug management" to patients taking medication for dementia. Factors related to medication adherence among patients and pharmacists' acquisition of patient information were then verified. The survey items were: (1) patient attributes (degree of care received, bed-ridden, family composition, and living environment); (2) the person controlling medications; (3) drug storage method and location; (4) dispensing method; (5) patient management of visiting nurses; (6) patient management of visiting physician; (7) details of pharmacist's home-visit guidance; (8) medication adherence; (9) five items related to cognitive function (short-term memory, autonomous judgment, fluctuations in level of consciousness, excitation and loss of orientation, understanding); and (10) ten items related of ADL (mobility in bed, transferring, mobility within the home or outdoors, dressing upper/lower body, eating, toilet use, individual hygiene, bathing). The t test was used to verify the number of items of patient information concerning cognitive function and physical function that pharmacists could acquire at a visit. It was suggested that pharmacists were able to acquire more patient information (①cognitive function and ②ADL) when they visited patients cared for at home, compared to facility residents (①p=0.008, ② p=0.006). Thus, it was suggested that there is a latent risk concerning the pharmacist's ability to discover problems with administration of medications among facility residents. These findings demonstrate that it is essential for pharmacists to be more proactive about providing home-visit guidance.

This study aimed to assess the effectiveness of chronic bilateral STN-S in improving the functional status of PD patients compared with patients treated with drugs alone. Controlled study of disability index changes over 12 and 24 month chronic STN stimulation. Of 39 patients with advanced PD meeting CAPSIT criteria for STN-S, 23 underwent surgery; 16 patients decided against surgery and continued on drug schedule adjustments. Functional status was measured using the Activities of Daily Living section of the Unified Parkinson's Disease Rating Scale (UPDRS-ADL), Brown's Disability Scale, and Functional Independence Measure. UPDRS motor score and subscores for selected items, levodopa equivalent daily dose, and Beck Depression Inventory scores were also monitored. T12 follow up data were available for all 39 patients and T24 data for 13 STN-S and 8 control subjects. Compared with controls, STN-S patients experienced significant or highly significant improvements in all independence measures at both 12 and 24 months (time x treatment effect T12: F = 19.5, p = 0.00008; T24: F = 6.2, p = 0.005). Forward stepwise regression for independent predictors of the yearly rate of UPDRS-ADL score modification in the entire sample showed that treatment was the only factor significantly associated with functional status change (beta coefficient -0.54, t value -2.5, p = 0.02), whereas other variables-UPDRS motor score, BDI, and age at disease onset and enrolment-were not in the equation. STN-S is an effective therapeutic option in advanced PD. It induced a consistent improvement of functional abilities over two years to an extent that was not achieved with drug therapy alone.

Malnutrition affects the activities of daily living (ADLs) in convalescent patients with cerebrovascular disorders. We investigated the relationship between nutritional improvement, energy intake at admission, and recovery of ADLs. We evaluated 67 patients with cerebrovascular disorders admitted to our rehabilitation hospital between April 2013 and April 2015. These patients received interventions from the rehabilitation nutritional support team according to the following criteria: weight loss of 2 kg or more and body mass index of 19 kg/m(2) or lower. Exclusion criteria included a body mass index of 25 kg/m(2) or higher, duration of intervention of less than 14 days, or transfer to an acute care hospital because of clinical deterioration. We assessed nutritional status using the Geriatric Nutritional Risk Index (GNRI) and ADL using the Functional Independence Measure (FIM) score, FIM gain, and FIM efficiency. The mean age of the patients was 78.7 ± 8.0 years. The numbers of patients in each category of cerebrovascular disorder were 39 with cerebral infarction, 16 with intracerebral hemorrhage, 8 with subarachnoid hemorrhage, and 4 others. Compared with the counterpart group, the group with an improvement in GNRI had a greater gain in FIM (median 17 and 20, respectively; P = .036) and a higher FIM efficiency (.14 and .22, respectively; P = .020). Multivariate stepwise regression analysis showed that an improvement in GNRI, increasing energy intake at admission, and intracerebral hemorrhage were associated independently with greater FIM efficiency. This study suggested that nutritional improvement and energy intake at admission are associated with recovery of ADL after cerebrovascular disorders. Copyright © 2015 National Stroke Association.

Background Patients who undergo hemodialysis encounter challenges including role changes, physical degeneration, and difficulty in performing activities of daily living (ADLs) and self-care. These challenges deteriorate their physiological and psychosocial conditions, resulting in depression. High resilience (RES) and social support can alleviate stress and depression. This study evaluated the importance of RES and social support in managing depression in elderly patients undergoing maintenance hemodialysis (HD). Patients and methods In this descriptive, correlational study, 194 older patients undergoing HD were enrolled from the HD centers of three hospitals in northern Taiwan. The Barthel ADL Index, RES scale, Inventory of Socially Supportive Behavior, and Beck Depression Inventory-II were used. Hierarchical regression analysis was applied to evaluate the interaction of RES and social support with illness severity, demographics, and ADLs. Results Of the total participants, 45.9% experienced depressive symptoms. Demographic analysis showed that men and those with high educational level and income and financial independence had less depression (p<0.01). Patients with a higher Barthel Index (n=103), RES scale (n=33), and social support (n=113) showed less depressive symptoms (p<0.01). We found a significant negative correlation between depressive symptoms and social support (r=−0.506, p<0.01) and RES (r=−0.743, p<0.01). Hierarchical regression analysis showed that RES could buffer the effects of symptom severity on depression (b=−0.436, p<0.01), but social support did not exert a buffering effect. Conclusion The severity of illness symptoms and ADLs were the major determinants of depressive symptoms. High RES could alleviate depressive symptoms in the older patients undergoing HD.

Mobile geriatric rehabilitation is an outpatient rehabilitative treatment in which a multidisciplinary team treats elderly patients at home. This kind of treatment has been performed in rare cases in Germany but there are no data available on the effectiveness in patients with severe cognitive and functional impairment. In a retrospective study design the data of all patients who had participated in mobile geriatric rehabilitation between 1 September 2009 and 23 May 2011 were evaluated. Before treatment a comprehensive geriatric assessment was performed and after treatment an assessment of mobility and activities of daily living (ADL). After 6 months a random sample of 20 patients were contacted by telephone to check the ADL. A total of 87 patients were treated between 1 September 2009 and 23 May 2011. The median age was 83 years and 56 % of the patients lived in nursing homes. Only 24 % of the patients had MMSE scores > 23 points, 77 patients completed the treatment with an assessment and in these patients the ADL could be improved significantly (Barthel index at the beginning 36.2 points and on completion 50.9 points, p < 0.001). The Barthel index 6 months after treatment was only 1.25 points lower compared to the assessment at the end of the treatment. Significant improvement after therapy could also be demonstrated in the mobility assessment (timed up and go test, Tinetti mobility score and Esslinger transfer scale). The results of this non-randomized and non-blinded trial indicated the efficacy of mobile geriatric rehabilitation. In functionally and cognitively impaired elderly patients ADL and mobility can be improved. These effects seem to persist for at least for 6 months.

The aim of this study is to investigate the psychometrics of the 12 items of an instrument assessing activities of daily living (ADL) using an item response theory model. A total of 648 adults with physical disabilities and having difficulties in ADLs were retrieved from the 2014 Korean National Survey on People with Disabilities. The psychometric testing included factor analysis, internal consistency, precision, and differential item functioning (DIF) across categories including sex, older age, marital status, and physical impairment area. The sample had a mean age of 69.7 years old (SD = 13.7). The majority of the sample had lower extremity impairments (62.0%) and had at least 2.1 chronic conditions. The instrument demonstrated unidimensional construct and good internal consistency (Cronbach's alpha = 0.95). The instrument precisely estimated person measures within a wide range of theta values (-2.22 logits < θ < 0.27 logits) with a reliability of 0.9. Only the changing position item demonstrated misfit (χ 2  = 36.6, df = 17, p = 0.0038), and the dressing item demonstrated DIF on the impairment type (upper extremity/others, McFadden's Pseudo R 2  > 5.0%). Our findings indicate that the dressing item would need to be modified to improve its psychometrics. Overall, the ADL instrument demonstrates good psychometrics, and thus, it may be used as a standardized instrument for measuring disability in rehabilitation contexts. However, the findings are limited to adults with physical disabilities. Future studies should replicate psychometric testing for survey respondents with other disorders and for children.

Abstract Background. We examined physical functioning (PF) trajectories (maintaining, slowly declining, and rapidly declining) spanning 15 years in older women aged 65–80 and protective factors that predicted better current levels and less decline in functional independence outcomes after age 80. Methods. Women’s Health Initiative extension participants who met criteria (enrolled in either the clinical trial or observational study cohort, >80 years at the data release cutoff, PF survey data from initial enrollment to age 80, and functional independence survey data after age 80) were included in these analyses (mean [ SD ] age = 84.0 [1.4] years; N = 10,478). PF was measured with the SF-36 (mean = 4.9 occasions). Functional independence was measured by self-reported level of dependence in basic and instrumental activities of daily living (ADLs and IADLs) (mean = 3.4 and 3.3 occasions). Results. Maintaining consistent PF in older adulthood extends functional independence in ADL and IADL in late-life. Protective factors shared by ADL and IADL include maintaining PF over time, self-reported excellent or very good health, no history of hip fracture after age 55, and no history of cardiovascular disease. Better IADL function is uniquely predicted by a body mass index less than 25 and no depression. Less ADL and IADL decline is predicted by better self-reported health, and less IADL decline is uniquely predicted by having no history of hip fracture after age 55. Conclusions. Maintaining or improving PF and preventing injury and disease in older adulthood (ages 65–80) has far-reaching implications for improving late-life (after age 80) functional independence.

Background The purpose of this study was to assess the association between skeletal muscle mass, activities of daily living (ADLs) and severe dysphagia in cancer patients. Methods A nested case-control study was performed in 111 consecutive cancer patients with dysphagia who were prescribed speech therapy. Skeletal muscle mass comprising the cross-sectional area of the left and right psoas muscles was assessed via abdominal computed tomography at the third lumbar vertebral level. ADLs were evaluated by the Barthel Index. The severity of dysphagia was assessed by the Food Intake Level Scale and was characterized by non-oral feeding or oral food intake at discharge. Univariate and logistic regression analyses were applied to examine the associations between dysphagia, skeletal muscle index (SMI) and ADLs. Results There were 86 men and 25 women (mean age, 70 years). The mean SMI was 5.68 ± 1.74 cm2/m2 in men and 4.43 ± 1.21 cm2/m2 in women. The median Barthel Index score was 20. Thirty-three patients were on non-oral feeding at discharge. The mean SMI did not differ significantly between non-oral feeding and oral food intake groups in t-test. The median Barthel Index score was lower in the non-oral feeding group in Mann–Whitney U test. Logistic regression analysis of the severity of dysphagia adjusted for age, sex, SMI, Barthel Index score, serum albumin, cancer type and stage, and vocal cord paralysis showed that SMI was associated independently with oral food intake at discharge. Barthel Index score showed a tendency to be associated with oral food intake. Conclusions Skeletal muscle mass is associated with severe dysphagia in cancer patients. ADLs show a tendency to be associated with severe dysphagia in cancer patients. PMID:26673551

Most survivors of an aneurysmal subarachnoid hemorrhage (aSAH) are ADL-independent, but they often experience restrictions in (social) activities and, therefore, cannot regain their pre-morbid level of participation. In this study, participation restrictions and participation satisfaction experienced after aSAH were assessed. Moreover, possible predictors of participation after aSAH were examined to identify goals for rehabilitation. Participation restrictions experienced by a series of 67 patients visiting our SAH outpatient clinic were assessed as part of standard clinical care using the Participation Restrictions and Satisfaction sections of the Utrecht Scale for Evaluation of Rehabilitation Participation (USER-Participation) 6 months after aSAH. Cognitive impairments, cognitive and emotional complaints, and symptoms of depression and anxiety, assessed 10 weeks after aSAH, were examined as possible predictors of participation by means of linear regression analysis. Although patients were ADL-independent, 64% reported one or more participation restrictions and 60% were dissatisfied in one or more participation domains. Most commonly experienced restrictions concerned housekeeping, chores in and around the house, and physical exercise. Dissatisfaction was most often reported about outdoor activities, mobility, and work/housekeeping. The main predictors of participation restrictions as well as satisfaction with participation were cognitive complaints (subjective) (β = -.30, p = .03 and β = -.40, p = .002, respectively) and anxiety (β = .32, p = .02 and β = -.34, p = .007, respectively). Almost two-thirds of the ADL-independent patients experienced problems of participation 6 months after aSAH. Cognitive complaints (subjective) and anxiety symptoms showed the strongest association with participation restrictions and satisfaction. Cognitive rehabilitation and anxiety-reducing interventions may help to optimize rehabilitation and increase participation after aSAH.

To characterize patient-level clinically meaningful improvements in pain and limitation of key activities of daily living (ADLs) after primary or revision total hip arthroplasty (THA). We analysed prospectively collected data from the Mayo Clinic Total Joint Registry to study clinically meaningful improvements in index hip pain severity and limitation in seven key ADLs (walking, climbing stairs, putting on shoes/socks, picking up objects, getting in/out of car, rising from a chair and sitting), from preoperative to 2- and 5-year post-THA. The primary THA cohort consisted of 6168 responders preoperatively, 5707 at 2 years and 3289 at 5 years postoperatively. The revision THA cohort consisted of 2063 responders preoperatively, 2682 at 2 years and 1627 at 5 years postoperatively. In the primary THA cohort, clinically meaningful pain reduction to mild or no hip pain at 2 years was reported by 94% with moderate and 91% with severe preoperative pain; respective proportions were 91% and 89% at 5-year follow-up. For revision THA, respective proportions were 84% and 77% at 2 years and 80% and 78% at 5 years. In the primary THA cohort, up to 4% with moderate and 17% with severe preoperative ADL limitation reported severe limitation in the respective activity 2 years post-primary THA; at 5 years, the respective proportions were up to 7% and 20%. Respective proportions for revision THA were up to 10% and 26% at 2 years and 13% and 30% at 5 years. These comprehensive data for patient-level clinically meaningful improvements in pain and seven key ADLs can help patients set realistic goals for improvement after THA.

To describe the correlation between the functional dysphagia scale and aspiration pneumonia and which characteristics influence the occurrence of aspiration pneumonia in patients with idiopathic Parkinson disease. Fifty-three patients with idiopathic Parkinson disease were prospectively evaluated in this study. Disease severity and functional status were measured by modified Hoehn and Yahr (H&Y) staging, Schwab and England activities of daily living (S-E ADL) scale and Korean version of Mini-Mental State Examination (K-MMSE). Swallowing function was evaluated by the functional dysphagia scale (FDS) and the penetration-aspiration scale (PAS) based on a videofluoroscopic swallowing study. The patients were followed up for 3 months and divided into two groups according to the occurrence of aspiration pneumonia. The correlation between the variables and aspiration pneumonia was analyzed. Eight patients of the 53 patients were allocated to the aspiration pneumonia group and 45 patients to the non-aspiration pneumonia group. The patients in the aspiration pneumonia group had significantly higher H&Y staging, and scored lower on S-E ADL scale and K-MMSE. The patients in the aspiration pneumonia group had significantly higher scores on FDS and PAS. A multiple logistic regression analysis showed that the S-E ADL scale and the FDS were associated with the occurrence of aspiration pneumonia in the patients with Parkinson disease. Given that the FDS can quantitatively assess the functional problems associated with dysphagia, it can be clinically effective in predicting the occurrence of aspiration pneumonia, and the FDS and the S-E ADL scale could be predictive variables for aspiration pneumonia in patients with Parkinson disease.

Kinematic analysis has been used to objectively evaluate movement patterns, quality, and strategies during reaching tasks. However, no study has investigated whether kinematic variables during unilateral and bilateral reaching tasks predict a patient's perceived arm use during activities of daily living (ADL) after an intensive intervention. Therefore, this study investigated whether kinematic measures during unilateral and bilateral reaching tasks before an intervention can predict clinically meaningful improvement in perceived arm use during ADL after intensive poststroke rehabilitation. The study was a secondary analysis of 120 subjects with chronic stroke who received 90-120 min of intensive intervention every weekday for 3-4 weeks. Reaching kinematics during unilateral and bilateral tasks and the Motor Activity Log (MAL) were evaluated before and after the intervention. Kinematic variables explained 22 and 11 % of the variance in actual amount of use (AOU) and quality of movement (QOM), respectively, of MAL improvement during unilateral reaching tasks. Kinematic variables also explained 21 and 31 % of the variance in MAL-AOU and MAL-QOM, respectively, during bilateral reaching tasks. Selected kinematic variables, including endpoint variables, trunk involvement, and joint recruitment and interjoint coordination, were significant predictors for improvement in perceived arm use during ADL (P < 0.05). Arm-trunk kinematics may be used to predict clinically meaningful improvement in perceived arm use during ADL after intensive rehabilitation. Involvement of interjoint coordination and trunk control variables as predictors in bilateral reaching models indicates that a high level of motor control (i.e., multijoint coordination) and trunk stability may be important in obtaining treatment gains in arm use, especially for bilateral daily activities, in intensive rehabilitation after stroke.

Background The World Health Organisation recommends that services accompany wheelchair distribution. This study examined the relationship of wheelchair service provision in Kenya and the Philippines and wheelchair-use–related outcomes. Method We surveyed 852 adult basic manual wheelchair users. Participants who had received services and those who had not were sought in equal numbers from wheelchair-distribution entities. Outcomes assessed were daily wheelchair use, falls, unassisted outdoor use and performance of activities of daily living (ADL). Descriptive, bivariate and multivariable regression model results are presented. Results Conditions that led to the need for a basic wheelchair were mainly spinal cord injury, polio/post-polio, and congenital conditions. Most Kenyans reported high daily wheelchair use (60%) and ADL performance (80%), while these practices were less frequent in the Philippine sample (42% and 74%, respectively). Having the wheelchair fit assessed while the user propelled the wheelchair was associated with greater odds of high ADL performance in Kenya (odds ratio [OR] 2.8, 95% confidence interval [CI] 1.6, 5.1) and the Philippines (OR 2.8, 95% CI 1.8, 4.5). Wheelchair-related training was associated with high ADL performance in Kenya (OR 3.2, 95% CI 1.3, 8.4). In the Philippines, training was associated with greater odds of high versus no daily wheelchair use but also odds of serious versus no falls (OR 2.5, 95% CI 1.4, 4.5). Conclusion Select services that were associated with some better wheelchair use outcomes and should be emphasised in service delivery. Service providers should be aware that increased mobility may lead to serious falls. PMID:29134178

To determine the effect of fall-related concerns on physical, mental, and social function. Community-based prospective cohort study (secondary analysis using control group data from a randomized controlled trial). Two municipalities in the south of the Netherlands. Community-dwelling older adults (N = 260). Two groups were created using Modified Falls Efficacy Scale scores (high and low levels of fall-related concerns). Five outcome measures representing physical, mental, and social function were included: activities of daily living (ADLs), symptoms of depression, feelings of anxiety, social participation, and social support interactions. Outcomes were measured at baseline and at 2, 8, and 14 months. Data were analyzed using analysis of covariance and mixed-effect regression models for longitudinal data, adjusting for age, sex, living status (alone or with another person), educational level, cognitive status, self-perceived health, and falls history at baseline. At baseline, significantly more limitations in ADLs and social participation were found for older persons with high levels of fall-related concerns than for those with low levels of concern. These differences persisted over 14 months of follow-up and were consistent over time. No significant differences were found for symptoms of depression, feelings of anxiety, or social support interactions, except for feelings of anxiety at 14 months. Older persons with higher levels of fall-related concerns reported up to 14 months poorer ADL and social participation for up to 14 months than those with lower levels of fall-related concerns. From a clinical point of view, the clear relationship between fall-related concerns and ADL dysfunction and social participation may help to target groups who are at risk of developing adverse consequences of concerns about falls. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

Previous studies have linked higher religious attendance and longer survival. In this study, we examine the relationship between survival and private religious activity. A probability sample of elderly community-dwelling adults in North Carolina was assembled in 1986 and followed for 6 years. Level of participation in private religious activities such as prayer, meditation, or Bible study was assessed by self-report at baseline, along with a wide variety of sociodemographic and health variables. The main outcome was time (days) to death or censoring. During a median 6.3-year follow-up period, 1,137 subjects (29.5%) died. Those reporting rarely to never participating in private religious activity had an increased relative hazard of dying over more frequent participants, but this hazard did not remain significant for the sample as a whole after adjustment for demographic and health variables. When the sample was divided into activity of daily living (ADL) impaired and unimpaired, the effect did not remain significant for the ADL impaired group after controlling for demographic variables (hazard ratio [RH] 1.11, 95% confidence interval [CI] 0.91-1.35). However, the increased hazard remained significant for the ADL unimpaired group even after controlling for demographic and health variables (RH 1.63, 95% CI 1.20-2.21), and this effect persisted despite controlling for numerous explanatory variables including health practices, social support, and other religious practices (RH 1.47, 95% CI 1.07-2.03). Older adults who participate in private religious activity before the onset of ADL impairment appear to have a survival advantage over those who do not.

In France, the prevalence of stroke and the level of disability of stroke survivors are little known. The aim of this study was to evaluate functional limitations in adults at home and in institutions, with and without self-reported stroke. A survey named "the Disability Health survey" was carried out in people's homes (DHH) and in institutions (DHI). Medical history and functional level (activities-of-daily-living, ADL and instrumented-activities-of-daily-living IADL) were collected through interviews. The modified Rankin score (mRS) and the level of dependence and disability were compared between participants with and without stroke. 33896 subjects responded. The overall prevalence of stroke was 1.6% (CI95% [1.4%-1.7%]). The mRS was over 2 for 34.4% of participants with stroke (28.7% of participants at home and 87.8% of participants in institutions) versus respectively 3.9%, 3.1% and 71.6% without stroke. Difficulty washing was the most frequently reported ADL for those with stroke (30.6% versus 3% for those without stroke). Difficulty with ADL and IADL increased with age but the relative risk was higher below the age of 60 (17 to 25) than over 85 years (1.5 to 2.2), depending on the ADL. In the overall population, 22.6% of those confined to bed or chair reported a history of stroke. These results thus demonstrate a high national prevalence of stroke. Older people are highly dependent, irrespective of stroke history and the relative risk of dependence in young subjects with a history of stroke is high compared with those without.

To evaluate the predictive value of muscle strength and physical performance in the oldest old for all-cause mortality; hospitalization; and the onset of disability, defined as a decline in activities of daily living (ADLs), independent of muscle mass, inflammatory markers, and comorbidities. A prospective, observational, population-based follow-up study. Three well-circumscribed areas of Belgium. Five hundred sixty participants aged 80 and older were followed for 33.5 months (interquartile range 31.1-35.6 months). Grip strength, Short Physical Performance Battery (SPPB) score, and muscle mass were measured at baseline; ADLs at baseline and after 20 months; and all-cause mortality and time to first hospitalization from inclusion onward. Kaplan-Meier curves and Cox proportional hazards models were calculated for all-cause mortality and hospitalization. Logistic regression analysis was used to determine predictors of decline in ADLs. Kaplan-Meier curves showed significantly higher all-cause mortality and hospitalization in subjects in the lowest tertile of grip strength and SPPB score. The adjusted Cox proportional hazards model showed that participants with high grip strength or a high SPPB score had a lower risk of mortality and hospitalization, independent of muscle mass, inflammatory markers, and comorbidity. A relationship was found between SPPB score and decline in ADLs, independent of muscle mass, inflammation, and comorbidity. In people aged 80 and older, physical performance is a strong predictor of mortality, hospitalization, and disability, and muscle strength is a strong predictor of mortality and hospitalization. All of these relationships were independent of muscle mass, inflammatory markers, and comorbidity. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.

Muscle weakness-which can result from neurological injuries, genetic disorders, or typical aging-can affect a person's mobility and quality of life. For many people with muscle weakness, assistive devices provide the means to regain mobility and independence. These devices range from well-established technology, such as wheelchairs, to newer technologies, such as exoskeletons and exosuits. For assistive devices to be used in everyday life, they must provide assistance across activities of daily living (ADLs) in an unobtrusive manner. This article introduces the Myosuit, a soft, wearable device designed to provide continuous assistance at the hip and knee joint when working with and against gravity in ADLs. This robotic device combines active and passive elements with a closed-loop force controller designed to behave like an external muscle (exomuscle) and deliver gravity compensation to the user. At 4.1 kg (4.6 kg with batteries), the Myosuit is one of the lightest untethered devices capable of delivering gravity support to the user's knee and hip joints. This article presents the design and control principles of the Myosuit. It describes the textile interface, tendon actuators, and a bi-articular, synergy-based approach for continuous assistance. The assistive controller, based on bi-articular force assistance, was tested with a single subject who performed sitting transfers, one of the most gravity-intensive ADLs. The results show that the control concept can successfully identify changes in the posture and assist hip and knee extension with up to 26% of the natural knee moment and up to 35% of the knee power. We conclude that the Myosuit's novel approach to assistance using a bi-articular architecture, in combination with the posture-based force controller, can effectively assist its users in gravity-intensive ADLs, such as sitting transfers.

Transcranial Direct Current Stimulation (tDCS) is an emerging approach for improving capacity in activities of daily living (ADL) and upper limb function after stroke. However, it remains unclear what type of tDCS stimulation is most effective. Our aim was to give an overview of the evidence network regarding the efficacy and safety of tDCS and to estimate the effectiveness of the different stimulation types. We performed a systematic review of randomised trials using network meta-analysis (NMA), searching the following databases until 5 July 2016: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, CINAHL, AMED, Web of Science, and four other databases. We included studies with adult people with stroke. We compared any kind of active tDCS (anodal, cathodal, or dual, that is applying anodal and cathodal tDCS concurrently) regarding improvement of our primary outcome of ADL capacity, versus control, after stroke. CRD42016042055. We included 26 studies with 754 participants. Our NMA showed evidence of an effect of cathodal tDCS in improving our primary outcome, that of ADL capacity (standardized mean difference, SMD = 0.42; 95% CI 0.14 to 0.70). tDCS did not improve our secondary outcome, that of arm function, measured by the Fugl-Meyer upper extremity assessment (FM-UE). There was no difference in safety between tDCS and its control interventions, measured by the number of dropouts and adverse events. Comparing different forms of tDCS shows that cathodal tDCS is the most promising treatment option to improve ADL capacity in people with stroke.

Background Many older adults with dementia require constant assistance from a caregiver when completing activities of daily living (ADL). This study examines the efficacy of a computerized device intended to assist people with dementia through ADL, while reducing caregiver burden. The device, called COACH, uses artificial intelligence to autonomously guide an older adult with dementia through the ADL using audio and/or audio-video prompts. Methods Six older adults with moderate-to-severe dementia participated in this study. Handwashing was chosen as the target ADL. A single subject research design was used with two alternating baseline (COACH not used) and intervention (COACH used) phases. The data were analyzed to investigate the impact of COACH on the participants' independence and caregiver burden as well as COACH's overall performance for the activity of handwashing. Results Participants with moderate-level dementia were able to complete an average of 11% more handwashing steps independently and required 60% fewer interactions with a human caregiver when COACH was in use. Four of the participants achieved complete or very close to complete independence. Interestingly, participants' MMSE scores did not appear to robustly coincide with handwashing performance and/or responsiveness to COACH; other idiosyncrasies of each individual seem to play a stronger role. While the majority (78%) of COACH's actions were considered clinically correct, areas for improvement were identified. Conclusion The COACH system shows promise as a tool to help support older adults with moderate-levels of dementia and their caregivers. These findings reinforce the need for flexibility and dynamic personalization in devices designed to assist older adults with dementia. After addressing identified improvements, the authors plan to run clinical trials with a sample of community-dwelling older adults and caregivers. PMID:18992135

To evaluate the effects of a protein-rich liquid supplementation, alone or in combination with the anabolic steroid nandrolone decanoate, on body composition, activities of daily living (ADL) status and the health-related quality of life (HRQoL) after a femoral neck fracture. Sixty women, aged 83 +/- 5 years (mean +/- SD), BMI < 24 kg/m2 (20.4 +/- 2 kg/m2 ) and capable of co-operating, with a femoral neck fracture treated with internal fixation, were randomised to open treatment during 6 months with a protein-rich liquid formula alone (PR, Fortimel, 200 ml/day, 20 g protein/day) or in combination with nandrolone decanoate (PR/N, Deca-Durabol 25 mg i.m./3 weeks) or to a control group (C). The patients were re-examined after 6 and 12 months regarding body weight (BW), lean body mass (LBM, DXA), ADL status according to Katz, HRQoL according to EQ 5-D and fracture healing. LBM decreased in the C (-1.2 +/- 2 kg) and PR groups (-1.2 +/- 1 kg) but remained the same in the PR/N group (0.3 +/- 1 kg) (P < 0.05 between groups). ADL remained at a high level in the two intervention groups but declined significantly in the C group (P < 0.005 between groups). The decline in HRQoL was least pronounced in the PR/N group at 6 months (P < 0.05 between groups). Patients with fracture healing complications lost more BW (P < 0.05) and LBM (P < 0.01) than patients with uneventful fracture healing. Protein-rich liquid supplementation in combination with nandrolone given for 6 months to lean elderly women after a femoral neck fracture may positively affect LBM, ADL and HRQoL.

Grossberg, George T.; Somogyi, Monique; Meng, Xiangyi

2011-01-01

Objective: The cholinesterase inhibitor rivastigmine is approved for the treatment of mild to moderate Alzheimer's disease. However, it is not possible to predict which individuals will benefit from treatment. This retrospective analysis of an international, 24-week, randomized, double-blind trial aimed to identify the percentage of persons with Alzheimer's disease who have a sustained response with rivastigmine patch, rivastigmine capsules, or placebo; to determine the magnitude of the sustained treatment response; and to investigate baseline patient characteristics predictive of the observed sustained response. Method: Patients who improved on the Alzheimer's Disease Assessment Scale-cognitive subscale (ADAS-cog) and Alzheimer's Disease Cooperative Study-Activities of Daily Living scale (ADCS-ADL) at week 16 and maintained at least the week 16 improvement at week 24 were identified as sustained responders. Treatment differences and baseline predictive factors were assessed in patients demonstrating a 1-, 2-, 3-, 4-, or 5-point sustained improvement. The first patient was screened in November 2003 and the last patient completed the study in January 2006. Results: More persons with Alzheimer's disease had sustained improvements on the ADAS-cog and ADCS-ADL with rivastigmine versus placebo. Sustained improvements of 4 or 5 points on the ADAS-cog or ADCS-ADL were demonstrated in the 9.5-mg/24-h rivastigmine patch (24% and 36% of patients, respectively) and 12-mg/d capsule groups (28% on both outcome measures). Factors predictive of a sustained response to treatment included baseline Mini-Mental State Examination, ADAS-cog, and ADCS-ADL scores and treatment, country of treatment, and time since first symptom was diagnosed by a physician. Conclusions: Understanding factors predictive of sustained cholinesterase inhibitor treatment response should help to optimize Alzheimer's disease management and encourage compliance by allowing more realistic expectations of treatment effects.

For early inpatient stroke rehabilitation, the effectiveness of amphetamine combined with physiotherapy varies across studies. To investigate whether the recovery of activities of daily living (ADL, primary outcome) and motor function (secondary outcome) can be improved by dexamphetamine added to physiotherapy. In a double-blind, placebo-controlled trial, 16 patients, from 918 who were screened, were randomized to the experimental group (EG, dexamphetamine + physiotherapy) or control group (CG, placebo + physiotherapy). Both groups received multidisciplinary inpatient rehabilitation. Dexamphetamine (10 mg oral) or placebo was administered 2 days per week before physiotherapy. ADL and motor function were measured using the Chedoke-McMaster Stroke Assessment (CMSA) twice during baseline, every week during the 5-week treatment period, and at follow-up 1 week, 6 months, and 12 months after intervention. The majority of ineligible patients had too little paresis, were on anticoagulants, or had a stroke >60 days prior to entry. Participants (EG, n = 7, age 70.3 ± 10 years, 5 women, 37.9 ± 9 days after stroke; CG, n = 9, age 65.2 ± 17 years, 3 women, 40.3 ± 9 days after stroke) did not differ at baseline except for the leg subscale. Analysis of variance from baseline to 1 week follow-up revealed significant improvements in favor of EG for subscales ADL (P = .023) and arm function (P = .020) at end of treatment. No adverse events were detected. In this small trial that was based on prior positive trials, significant gains in ADL and arm function suggest that the dose and timing of dexamphetamine can augment physiotherapy. Effect size calculation suggests inclusion of at least 25 patients per group in future studies.

Impact of Balance Confidence on Daily Living Activities of Older People with Knee Osteoarthritis with Regard to Balance, Physical Function, Pain, and Quality of Life - A Preliminary Report.

2018-01-01

The objective of this study was to explore the impact of balance confidence on different activities of daily living (ADL) in older people with knee osteoarthritis (OA). Forty-seven consecutive participants with knee OA were included in this cross-sectional study. They were divided according to the results of the Activities-specific Balance Confidence (ABC) Scale into a group with a low level of confidence in physical functioning (ABC < 50, n = 22) and a group with moderate and high levels of confidence (ABC ≥ 50, n = 25). In the ABC < 50 group, the effect of pain on ADL, the physician's global assessment of the disease, and the Western Ontario and McMaster Universities Osteoarthritis Index scores were significantly higher, while quality of life (Short form-36) was lower compared to the ABC ≥ 50 group. No significant difference was found between the two groups regarding the static and dynamic balance measurements. Older people with knee OA who were less confident in their daily physical activities had more physical difficulties and a greater effect of pain on ADL, lower quality of life, and a higher physician's global assessment, but no differences were obtained in balance tests. In people with knee OA, decreased balance confidence is associated with more physical difficulties, an increased effect of pain on ADL, and lower quality of life. An improved awareness of decreased balance confidence may lead to more effective management of older people with knee OA by improving their mobility and QOL through rehabilitation. Furthermore, future research in that direction is warranted.

Sarcopenia is a geriatric syndrome, which affects the functional status and mobility of individuals. To identify the prevalence of sarcopenia and undernutrition, and to assess the association between sarcopenia and mobility, and sarcopenia and basic activities of daily living (ADL) in a group of elderly women. A cross-sectional study was performed in patients attending a geriatric service at a government hospital in Mexico City. Sarcopenia was identified applying Baumgartner's equation by obtaining skeletal muscle mass index (SMI) and undernutrition was diagnosed using mini-nutritional assessment instrument (MNA). The SENECA questionnaire and Katz index were used to evaluate mobility and ADL, respectively. lineal regression models were constructed fitting SMI as a dependent variable and SENECA, and ADL scores as independent variables, adjusted for age. 90 women with a mean age of 78.2 (± 6.8) were studied. Undernutrition was identified in 15.5% of the patients. The prevalence of sarcopenia was 41.1%. Patients with sarcopenia presented a high prevalence of undernutrition (p < 0.001). Sarcopenia was associated with difficulty in climbing stairs (OR = 2.63, p = 0.03), adjusted for age. The mobility score was associated with sarcopenia, in the group without sarcopenia the mean score was 16.3, and with sarcopenia it was 18.3, (p = 0.04). Regarding ADL, 64.9% of the patients with intermediate independence and dependence had sarcopenia, while 35.1% with total independence presented sarcopenia (p < 0.001). The elder women with sarcopenia had a higher prevalence of undernutrition. Sarcopenia was associated with difficulties in mobility, particularly difficulties in climbing stairs.

Platelet-leukocyte gel (PLG) is being used during various surgical procedures in an attempt to enhance the healing process. We studied the effects of PLG on postoperative recovery of patients undergoing open subacromial decompression (OSD). PLG was produced from platelet-leukocyte-rich plasma (P-LRP), prepared from a unit of whole blood. Forty patients were included in the study. Self-assessed evaluations, using the American Shoulder and Elbow Surgeons scoring system of activities of daily living (ADL), joint instability, pain levels, pain medications, and clinical evaluations for range of motion were conducted. Platelet and leukocyte counts were significantly increased in the P-LRP compared to baseline counts. Treated patients demonstrated decreased visual analog scales for pain and used significantly less pain medication, had an improved range of motion during passive forward elevation, external rotation, external rotation with arm at 90 degrees abduction, internal rotation, and cross body adduction compared to control patients (p < 0.001). No differences in the instability score were observed between the groups. Furthermore, treated patients performed more ADL (p < 0.05). In the PLG-treated group, recovery was faster and patients returned earlier to daily activities and also took less pain medication than control subjects. Copyright 2008 S. Karger AG, Basel.

This study aimed to examine associations between health status and care needs of nursing home residents and risk of death from suicide compared to other causes through a retrospective data linkage cohort study examining nursing home resident deaths in Australia between 2000 and 2013. Data linkage was performed between aged care assessment tools-Resident Classification System and Aged Care Funding Instrument-and the National Coronial Information System. A competing risks survival analysis was performed to determine the association between care assessment variables (activities of daily living (ADL), behavior, and complex health care) and the risk of death from suicide and any other cause. Of the 146 nursing home residents who died from suicide, 130 (89%) were matched to their assessment data, with comparable information available for 95 residents (65%). Residents who required high levels of care with ADL, physical health care, and cognitive and behavioral issues had a higher risk of dying from all other causes, yet lower risk of dying from suicide. The study findings demonstrate the feasibility and value of linking these two data sets; highlight a need for improved data collection processes; and support a person-centered care approach for prevention of suicide among nursing home residents. © 2018 The American Association of Suicidology.

Background. Region-specific types of neglect (peripersonal and extrapersonal) have been dissociated, yet, differential behavioural consequences are unknown. Objective. The aim of the current study was to investigate behavioural consequences at the level of basic activities of daily living of region-specific neglect, using the Catherine Bergego Scale (CBS). Methods. 118 stroke patients were screened within the first two weeks after admission to the rehabilitation center for inpatient rehabilitation. Results. Patients with peripersonal neglect and patients with neglect for both regions had significantly higher total score on the CBS compared to nonneglect patients. Total scores for patients with extrapersonal neglect were comparable to non-neglect patients. ADL impairments were found across activities (e.g., looking towards one side, forgetting body parts, colliding) for both patients with peripersonal neglect and patients with neglect for both regions. Patients with extrapersonal neglect were only impaired on the item on way finding. Conclusions. When diagnosing neglect, it is relevant to distinguish the type of region-specific neglect and, where needed, to adjust the rehabilitation program accordingly. As the CBS is not developed to typically measure ADL in extrapersonal neglect, it would be of importance to add other (instrumental) activities that heavily rely on processing information in farther space.

In this contribution a new centralized platform for telemedicine is presented. It combines functions for measuring of vital signs, ADL and behavioral patterns and is especially designed for home care scenarios and the use by elderly people who are not familiar with the use of a PC. Unlike many other approaches we did not use a modified standard PC but developed a new dedicated hardware platform. It comes with various interfaces to communicate with different medical home care systems. We implemented a modular software architecture, which allows managing multiple user accounts with different personal settings. Every account can be adapted individually to the user. Every medical device that can be connected to the platform has its own software module, in which data is analyzed, displayed, stored to an internal database or transmitted to a server. Though the user is not bothered with technical issues such as setting up a connection to the internet, he keeps control on his data because he decides if and when data is transferred to a web server. The device was developed in an iterative process and evaluated in focus groups by n = 31 subjects (average age: 67 years) under the supervision of a psychogerontologist. All findings obtained from those sessions were directly incorporated in the presented work.

In solid state fermentation, Pleurotus sajor-caju has been found to be able to degrade at least 30% oil palm empty Fruit Bunch (EFB) fibre leaving 70 % useful materials. Conditions under which fermentation carried out were investigated. It was found that, in the temperature range between 25- 28 °C, relative ph between 6-8, moisture between 60-70 % and medium composition of CaCO 3: rice bran 2 %: 5 % were the optimum conditions. The results showed in fermented products that, there were substantial reduction in cellulosic component such as Crude Fiber (CF, 18 %); Acid Detergent Fibre (ADF, 45 %), Neutral Detergent Fibre (NDF, 61 %) and Acid Detergent Lignin (ADL, 14 %). However, Crude Protein (CP, 10%) increased resulted from single cell protein enrichment of mycelial microbial mass. The mass reductions of substrate in fermentation process corresponds to the CO 2 released during fermentation. Hence, attributable to the decreased in content of CF, ADF, NDF, and ADL. The digestibility study has also been carried out to determine the useful level of this product to ruminant. Aflatoxin content was detected low in both the initial substrates and products. Based on nutritional value and low content of aflatoxin, the product is useful as a source of roughage to ruminant.

Individual and organizational characteristics associated with aggressive behavior among nursing home residents were examined among a sample of 5,494 residents from 23 facilities using the Minimum Data Set 2.0 and the Organizational Social Context scale. On admission, some individual level variables (age, sex, depression, activities of daily life [ADL] impairments, and cognitive impairments) and no organizational level variables were associated with aggressive behaviors. Over time, aggressive behaviors were linked with some individual characteristics (age, sex, and ADL impairments) and several organizational level variables (stressful climates, less rigid cultures, more resistant cultures, geographic location, facility size and staffing patterns). Findings suggest multi-faceted change strategies are needed.

This study determined whether there is an association between social capital and a composite outcome of decline in Activities of Daily Living (ADL) and death by gender. A prospective 3.5 year cohort study was conducted in a rural town in Japan. The study participants were 984 individuals aged 65 years and older with not impaired on ADL at 2010 baseline survey. Social participation and generalized trust were measured as social capital. The individual level responses were dichotomized and aggregated into the community level (eight areas). Multilevel logistic regression adjusting for covariates revealed that social participation at the individual level was significantly associated with higher odds of composite outcome (OR of "not participate" = 1.97, 95% CI = 1.38-2.81). Regarding generalized trust, only in men, there was an inverse association at the community level (OR of "low" = 0.55, 95% CI = 0.32-0.96), and a positive association at the individual level (OR of "tend to be careful" = 2.22, 95% CI = 1.27-3.90). These results suggest that social capital were associated with a decline in ADL and death and that the association may differ by gender.

This study was conducted to clarify the seasonal difference in body temperature in summer and winter, and to document the thermal environment of the elderly living in nursing homes. The subjects were 57 healthy elderly people aged >=63 years living in two nursing homes in Japan. One of the homes was characterized by subjects with low levels of activities of daily living (ADL). Oral temperatures were measured in the morning and afternoon, with simultaneous recording of ambient temperature and relative humidity. Oral temperatures in summer were higher than in winter, with statistically significant differences (P<0.05) of 0.25 (SD 0.61) °C in the morning and 0.24 (SD 0.50) °C in the afternoon. Differences between oral temperatures in summer and winter tended to be greater in subjects with low ADL scores, even when their room temperature was well-controlled. In conclusion, the oral temperatures of the elderly are lower in winter than summer, particularly in physically inactive people. It appears that those with low levels of ADL are more vulnerable to large changes in ambient temperature.

The purpose of the study was to analyse caregiver burden and consumption of psychosocial services in a consecutive group of patients with early onset Alzheimer's disease (EOAD) compared with a matching group with late onset Alzheimer's disease (LOAD). This was a case-control study with 42 patients who were matched according to disease severity at the time of diagnosis. Caregivers in both groups were interviewed using the Neuro Psychiatric Inventory (NPI), the Activities of Daily Living (ADL) scale and the Resource Utilization in Dementia scale. The quantitative outcomes were compared statistically. The EOAD group had a significantly higher ADL score than the LOAD group. There was a trend towards caregivers in the LOAD group spending more time helping the patients, and they needed more social services than the EOAD group. NPI scores were not significantly different, but a tendency towards a higher caregiver burden in the EOAD group was observed. The higher caregiver burden in patients with EOAD--despite a better ADL function than LOAD patients--suggests that the existing psychosocial services might be particularly insufficient for caregivers in EOAD. The study was funded by a three-month scholarship grant from the research fund at Roskilde Hospital. not relevant.

An increase in the accuracy of identification of Activities of Daily Living (ADL) is very important for different goals of Enhanced Living Environments and for Ambient Assisted Living (AAL) tasks. This increase may be achieved through identification of the surrounding environment. Although this is usually used to identify the location, ADL recognition can be improved with the identification of the sound in that particular environment. This paper reviews audio fingerprinting techniques that can be used with the acoustic data acquired from mobile devices. A comprehensive literature search was conducted in order to identify relevant English language works aimed at the identification of the environment of ADLs using data acquired with mobile devices, published between 2002 and 2017. In total, 40 studies were analyzed and selected from 115 citations. The results highlight several audio fingerprinting techniques, including Modified discrete cosine transform (MDCT), Mel-frequency cepstrum coefficients (MFCC), Principal Component Analysis (PCA), Fast Fourier Transform (FFT), Gaussian mixture models (GMM), likelihood estimation, logarithmic moduled complex lapped transform (LMCLT), support vector machine (SVM), constant Q transform (CQT), symmetric pairwise boosting (SPB), Philips robust hash (PRH), linear discriminant analysis (LDA) and discrete cosine transform (DCT).

Prosthetic hands are desired by those who have lost a hand or both hands not only for decoration but also for the functions to help them with their activities of daily living (ADL). Prosthetic robotic hands that are developed to fully realize the function of a human hand are usually too expensive to be economically available, difficult to operate and maintain, or over heavy for longtime wearing. The aim of this study is therefore to develop a simplified prosthetic hand (sim-PH), which is to be controlled by myoelectric signals from the user, to realize the most important grasp motions in ADL by trading off the cost and performance. This paper reports the structure design of a two-DoF sim-PH with two motors to drive the CM joint of the thumb and the interlocked MP joints of the other four fingers. In order to optimize the structure, the model of the sim-PH was proposed based on which 7 sim-PHs with different structural parameters were manufactured and tested in a pick-and-place experiment. Correspondence analysis of the experimental results clarified the relationship between the hand functions and the shapes of fingers.

We studied the relationship between kinematically unconstrained activities of daily living (ADL) tasks and a kinematically constrained task in above-elbow (AE) amputee subjects using myoelectrically controlled prostheses. Four men, 24 to 49 years old, with unilateral AE amputation wore a prosthesis interfaced to a programmable controller to emulate two different elbow control schemes, conventional velocity and a new "natural" controller. Subjects were timed during three ADL tasks--cutting meat, donning socks, and rolling dough--with both controllers. The prosthesis emulator was then connected to a crank device with a handle, and the subjects turned the crank from bottom to top positions in a vertical plane using each controller. Synergistic shoulder-elbow joint coordination required for crank turning was quantified as the maximum slope of the change in elbow torque versus the change in crank-angle. Performance between the two controllers differed significantly for the crank test but not for ADL tasks. One subject did not complete all crank turning tests. Positive canonical correlation of 0.77 was found between time and crank domain measures. We conclude that biomechanical assessments should be integrated with time-based clinical tests to comprehensively evaluate performance of AE amputee subjects with a myoelectric device.

Amyloid β Enhances Typical Rodent Behavior While It Impairs Contextual Memory Consolidation.

Alzheimer's disease (AD) is associated with an early hippocampal dysfunction, which is likely induced by an increase in soluble amyloid beta peptide (Aβ). This hippocampal failure contributes to the initial memory deficits observed both in patients and in AD animal models and possibly to the deterioration in activities of daily living (ADL). One typical rodent behavior that has been proposed as a hippocampus-dependent assessment model of ADL in mice and rats is burrowing. Despite the fact that AD transgenic mice show some evidence of reduced burrowing, it has not been yet determined whether or not Aβ can affect this typical rodent behavior and whether this alteration correlates with the well-known Aβ-induced memory impairment. Thus, the purpose of this study was to test whether or not Aβ affects burrowing while inducing hippocampus-dependent memory impairment. Surprisingly, our results show that intrahippocampal application of Aβ increases burrowing while inducing memory impairment. We consider that this Aβ-induced increase in burrowing might be associated with a mild anxiety state, which was revealed by increased freezing behavior in the open field, and conclude that Aβ-induced hippocampal dysfunction is reflected in the impairment of ADL and memory, through mechanisms yet to be determined.

The present study was targeted to observe the impact of neuropsychological rehabilitation on activities of daily living (ADL) and community reintegration of patients with traumatic brain injury (TBI). Based on purposive sampling technique, ten patients with TBI falling in the age range of 20-40 years and fulfilling the inclusion and exclusion criteria were chosen from All India Institute of Speech and Hearing, Mysuru, India. A quasi-experimental design, i.e., nonequivalent control group design was chosen for the study. Patients were assessed on Luria-Nebraska Neuropsychological Battery for Adults, Cognitive Symptoms Checklist, and Community Integration Questionnaire. Patients in experimental group were given neuropsychological rehabilitation for 6 months. Brainwave-R and Talking Pen were used as rehabilitative tools. Patients with TBI have significant neuropsychological deficits observed in memory, visuo-spatial organization, arithmetic, spelling, writing, fine motor coordination, and executive functioning. Neuropsychological deficits have a major impact on ADL and community reintegration. Neuropsychological rehabilitation is effective in rehabilitating neuropsychological deficits, which in turn leads to improvement in ADL and community reintegration. Neuropsychological rehabilitation should be one of the major goals in rehabilitation procedures for patients with TBI in order to bring overall improvement in them.

[Purpose] This study investigated the effect of aquatic proprioceptive neuromuscular facilitation (PNF) patterns in the lower extremity on balance and activities of daily living (ADL) in stroke patients. [Subjects] Twenty poststroke participants were randomly assigned to an experimental group (n = 10) or a control group (n = 10). The experimental group performed lower extremity patterns in an aquatic environment, and the control group performed lower extremity patterns on the ground. Both exercises were conducted for 30 minutes/day, 5 days/week for 6 weeks. Balance was measured with the Berg Balance Scale (BBS), Timed Up and Go Test (TUGT), Functional Reach Test (FRT), and One Leg Stand Test (OLST). Activities of daily living were measured with the Functional Independence Measure (FIM). A paired t-test was used to measure pre- and post-experiment differences, and an independent t-test was used to measure between-group differences. [Results] The experimental and control groups showed significant differences for all pre- and post-experiment variables. In the between-group comparison, the experimental group was significantly difference from the control group. [Conclusion] These results indicate that performing aquatic proprioceptive neuromuscular facilitation patterns in the lower extremity enhances balance and ADL in stroke patients.

The hypothesis of this study is that intensive therapy by means of a sensory and motor stimulation program of the upper limb in patients with chronic hemiparesis and severe disability due to stroke increases mobility and sensibility, and improves the use of the affected limb in activities of daily living (ADL). The program consists of 16 sessions of sensory stimulation and functional activity training in the rehabilitation center, and daily sessions of tactile stimulation, mental imaginery and practice of ADL at home, during 8 weeks. An experimental group (EG) of 12 patients followed this program, compared with a control group (CG) of 9 patients under standard rehabilitation. The efficacy of the program was evaluated by Fugl Meyer Assessment (FMA), Motor Activity Log (MAL) and Stroke Impact Scale-16 (SIS-16) scores, and a battery of sensory tests. The results show that in both groups, the motor FMA and the SIS-16 improved during the 8 weeks, this improvement being higher in the EG. Significant improvements were observed for the sensory tests in the EG. The intensive sensorimotor stimulation program for the upper extremity may be an efficacious method for improving function and use of the affected limb in ADL in chronic stroke patients.

Among the complementary and alternative medicine, Shiatsu might represent a feasible option for depression in Alzheimer's disease (AD). We evaluated Shiatsu on mood, cognition, and functional independence in patients undergoing physical activity. Single-blind randomized controlled study. Dedicated Community Center for patients with AD. AD patients with depression were randomly assigned to the "active group" (Shiatsu + physical activity) or the "control group" (physical activity alone). Shiatsu was performed by the same therapist once a week for ten months. Global cognitive functioning (Mini Mental State Examination - MMSE), depressive symptoms (Geriatric Depression Scale - GDS), and functional status (Activity of Daily Living - ADL, Instrumental ADL - IADL) were assessed before and after the intervention. We found a within-group improvement of MMSE, ADL, and GDS in the active group. However, the analysis of differences before and after the interventions showed a statistically significant decrease of GDS score only in the active group. The combination of Shiatsu and physical activity improved depression in AD patients compared to physical activity alone. The pathomechanism might involve neuroendocrine-mediated effects of Shiatsu on neural circuits implicated in mood and affect regulation. Copyright © 2018 Elsevier Ltd. All rights reserved.
