    We report on an activity monitoring system for elderly persons living alone. Caregivers would like to know whether the person is talking during their daily activity. Our monitoring system consists of a recorder and a personal computer. The recorder, attached to the subject's chest, employs two microphones, a tri-axis accelerometer, two low-power amplifiers, a low-power microcomputer (MC) and a 2GB micro SD Memory Card (SDMC). One of the microphones is set in the direction of the chest for recording the person's voice, and the other microphone is set to the opposite side for recording surrounding sound. The microphone outputs and the accelerometer outputs are sent to the MC’s 10 bit analog to digital converters and sampled at 4000Hz and 50Hz, respectively. The MC detects the length of the conversation time from the microphone outputs, and the posture and behavior are detected from the accelerometer outputs every 5 seconds. The detected time, posture and behavior are stored in the SDMC. The data can be downloaded from the memory card and sent to appropriate stations. The system is used to monitor the health and physical conditions during daily life of elderly persons living alone.

    2013-01-01

    Research on hoarding over the last two decades has shown that hoarding disorder appears to be a distinct disorder that burdens the individual, the community and the families of people who hoard. Although hoarding clearly interferes with the daily functioning, especially in the context of extensive clutter, no validated measures of this interference have been developed. The present research examined the psychometric properties of the Activities of Daily Living in Hoarding scale (ADL-H) in two large samples of individuals with significant hoarding problems, one identified through the internet (n=363) and a second through clinical diagnostic interviews (n=202). The ADL-H scale test-retest (1–12 weeks), interrater and internal reliabilities ranged from 0.79 to 0.96. Convergent and discriminant validity were established through analyses of correlational data collected for measures of hoarding severity and non-hoarding psychopathology (obsessive compulsive disorder [OCD], mood state, attention deficit, and perfectionism/uncertainty), as well as through comparisons of scores among individuals with hoarding, hoarding plus OCD, OCD without hoarding, and community controls. The ADL-H scale appears to have strong psychometric properties and to be useful in clinical and research settings. Suggestions are made for expansion of the scale, and study limitations are noted.

    In sub-Saharan Africa, various studies have been conducted on severe disability in activities of daily living, instrumental or domestic activities. These studies have reported different rates without describing the social context for understanding their results. This study was conducted in Burkina Faso to fill the gaps in scientific information on disability in these areas. We conducted a cross-sectional descriptive study in Bobo-Dioulasso among the older population, aged 60 and above. Their functional status was evaluated using the Functional Autonomy Measurement System (SMAF). Data analysis was done with the help of Stata. A systematic random sample of 351 aging adults was interviewed. Moderate to severe functional disability or the need for supervision or assistance was present in 7% in activities of daily living and 86% in instrumental or domestic activities of daily living. This need for assistance varied according to the different activities or items in each domain. The proportions of disability found in this study are higher than those of previous studies that measured the often severe disabilities. All persons with disability claimed to have stable human resources which help them to manage their disabilities. The social context instrumental or domestic activities of daily living are divided by generation and/or by sex. That explains some results. With this division, it's inacceptable in some family that elders and/or old men do instrumental or domestic activities of daily living as prepare meals, do laundry, carry water to wash. The variation of this division from one family to another complicates the assessment of functional disability. To best manage elders disabilities, strategies must develop to: 1) retard the resignation of the family in care of its elderly in functional disability, 2) anticipate the preparation of formal social networks, public structures to support the elderly.

    The objective of this study was to investigate whether some activities of daily living (ADLs) usually related to dyspnea sensation in patients with chronic obstructive pulmonary disease (COPD) are associated with dynamic lung hyperinflation (DH) and whether the use of simple energy conservation techniques (ECTs) might reduce this possible hyperinflation. Eighteen patients (mean age: 65.8 ± 9.8 years) with moderate-to-severe COPD performed six ADLs (walking on a treadmill, storing pots, walking 56 meters carrying a 5-kilogram weight, climbing stairs, simulating taking a shower, and putting on shoes) and had their inspiratory capacity (IC) measured before and after each task. The patients were moderately obstructed with forced expiratory volume in 1 second (FEV1): 1.4 ± 0.4 L (50% ± 12.4); FEV1/forced vital capacity: 0.4 ± 8.1; residual volume/total lung capacity: 52.7 ± 10.2, and a reduction in IC was seen after all six activities (p < 0.05): (1) going upstairs, 170 mL; (2) walking 56 meters carrying 5 kilogram weight, 150 mL; (3) walking on a treadmill without and with ECT, respectively, 230 mL and 235 mL; (4) storing pots without and with ECT, respectively, 170 mL and 128 mL; (5) taking a shower without and with ECT, respectively, 172 mL and 118 mL; and (6) putting on shoes without and with ECT, respectively, 210 mL and 78 mL). Patients with moderate to severe COPD develop DH after performing common ADLs involving the upper and lower limbs. Simple ECTs may avoid DH in some of these ADLs.

    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 10 years 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 10 years, had higher ADL scores and fewer surgical interventions than untreated patients. ADL scores for ERT patients (2.5 years follow-up on average) were similar with the-age-matched controls below 10 years 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.

    People's values influence their actions and efforts. Based on the assumption that a patient's values can be a guide to successful rehabilitation, the values of 15 activities of daily living as perceived by stroke patients and their home therapists were studied. Twenty-six stroke patients living at home and their 10 visiting occupational and physical therapists participated in the study. The study results indicated that the relative importance of each activity of daily living perceived by the patient group and by the therapist group was similar. Among the 29 therapist-patient pairs, however, only 1 pair showed significantly similar views regarding the values of these activities to the patient. Patients' age, gender, income level, duration since onset of stroke, impaired body side, and independence level in activities were significantly related to their values of certain activities of daily living. The relative value stroke patients living at home place on each activity of daily living could serve as a guide for sequencing learning steps during activities of daily living training in a hospital or rehabilitation setting. Determining patient rehabilitation goals as influenced by personal values may shorten rehabilitation time, be more cost-effective, and aid in the retention of gains made in the rehabilitation setting.

    A representative sample of the Leipzig population aged 75 years and older showed 61.8% of the participants with relevant deficits in their capacity for independent living, according to a combined activities of daily living/instrumental activities of daily living (ADL/IADL) scale. The quantity and quality of care needed almost exponentially increases above 85 years of age. Looking at potential reasons for ADL/IADL limitations, 44% of variance in single ADL/IADL activities and 75% of the combined ADL/IADL sum score could come from a minimal set of predictor variables. Most important are dementia- or mobility-related declines, but living conditions also explain small but significant amounts of variance. These seem initially impressive, yet analyses showed about half the explained variances shared among the mobility and dementia indicators, limiting the use not only of ADL/IADL sum scores but of many single ADL/IADL items as well. Before deriving specific conclusions from variations in ADL/IADL instruments, one must note that the data suggest that interpretations of covariations--whether for health/mobility or dementia--are useful and substantial only if both indicators/predictors are verified. The information given captures the mobility- and dementia-related variance if ADL/IADL items, facilitating more specific scale developments.

    OBJECTIVE To analyze gender differences in the incidence and determinants of disability regarding instrumental activities of daily living among older adults. METHODS The data were extracted from the Saúde, Bem-Estar e Envelhecimento (SABE – Health, Wellbeing and Ageing) study. In 2000, 1,034 older adults without difficulty in regarding instrumental activities of daily living were selected. The following characteristics were evaluated at the baseline: sociodemographic and behavioral variables, health status, falls, fractures, hospitalizations, depressive symptoms, cognition, strength, mobility, balance and perception of vision and hearing. Instrumental activities of daily living such as shopping and managing own money and medication, using transportation and using the telephone were reassessed in 2006, with incident cases of disability considered as the outcome. RESULTS The incidence density of disability in instrumental activities of daily living was 44.7/1,000 person/years for women and 25.2/1,000 person/years for men. The incidence rate ratio between women and men was 1.77 (95%CI 1.75;1.80). After controlling for socioeconomic status and clinical conditions, the incidence rate ratio was 1.81 (95%CI 1.77;1.84), demonstrating that women with chronic disease and greater social vulnerability have a greater incidence density of disability in instrumental activities of daily living. The following were determinants of the incidence of disability: age ≥ 80 and worse perception of hearing in both genders; stroke in men; and being aged 70 to 79 in women. Better cognitive performance was a protective factor in both genders and better balance was a protective factor in women. CONCLUSIONS The higher incidence density of disability in older women remained even after controlling for adverse social and clinical conditions. In addition to age, poorer cognitive performance and conditions that adversely affect communication disable both genders. Acute events, such as a stroke

    The objective of the study is to determine basic activities of daily living (Barthel Index) and instrumental activities of daily living (Lawton-Brody Index) before and after hip fracture. Follow-up study of patients (n=100) with hip fracture, operated at Complejo Hospitalario Universitario de A Coruña (Spain). Period January/2009-December/2011. Demographic characteristic of the patients, Charlson Index, Glomerular filtration rate, Barthel index, Lawton index, type of proximal femur fracture and surgical treatment delay were recorded. Multivariate regression was performed. Informed patient consent and ethical review approval were obtained. Before fracture were independent for activities of daily living (ADL) a 38.0%, at 90 days were 15.4%. The Barthel index score decreased from 75.2±28.2 to 56.5±31.8) (p<0.0001). If we consider the age, gender, comorbidity (Charlson index), renal function, fracture type and surgical delay objectify the only independent variable to predict dependency effect is age. If we also consider the Barthel score objectify the variable that significantly modifies that score at 90 days is the baseline value of the index. The prevalence of independence for instrumental activities of daily living (IADL) at the baseline moment is 11% and at 90 days is decreased to 2.2%. There is a decrease in the independence effect in all activities. The variable predictor of independence for all activities after taking into consideration age, sex, comorbidity, fracture type, surgical delay and renal function is the baseline score of the Barthel and Lawton index.

    Left-sided spatial neglect is a common neurological syndrome following right-hemispheric stroke. The presence of spatial neglect is a powerful predictor of poor rehabilitation outcome. In one influential account of spatial neglect, interhemispheric inhibition is impaired and leads to a pathological hyperactivity in the contralesional hemisphere, resulting in a biased attentional allocation towards the right hemifield. Inhibitory transcranial magnetic stimulation can reduce the hyperactivity of the contralesional, intact hemisphere and thereby improve spatial neglect symptoms. However, it is not known whether this improvement is also relevant to the activities of daily living during spontaneous behaviour. The primary aim of the present study was to investigate whether the repeated application of continuous theta burst stimulation trains could ameliorate spatial neglect on a quantitative measure of the activities of daily living during spontaneous behaviour. We applied the Catherine Bergego Scale, a standardized observation questionnaire that can validly and reliably detect the presence and severity of spatial neglect during the activities of daily living. Eight trains of continuous theta burst stimulation were applied over two consecutive days on the contralesional, left posterior parietal cortex in patients suffering from subacute left spatial neglect, in a randomized, double-blind, sham-controlled design, which also included a control group of neglect patients without stimulation. The results showed a 37% improvement in the spontaneous everyday behaviour of the neglect patients after the repeated application of continuous theta burst stimulation. Remarkably, the improvement persisted for at least 3 weeks after stimulation. The amelioration of spatial neglect symptoms in the activities of daily living was also generally accompanied by significantly better performance in the neuropsychological tests. No significant amelioration in symptoms was observed after sham

    A decline in instrumental activities of daily living has been described as the earliest functional deficit in patients with neurodegenerative disease. It embraces specific competencies such as: "recalling the date and telephone calls, orienting to new places, remembering the location of objects at home, understanding conversation and the plot of a movie, keeping belongings in order, doing mental calculations and handling money, remembering appointments and shopping lists and performing clerical work". Since changes in instrumental daily living activities are one of the descriptors of behavioural-variant frontotemporal dementia, we decided to investigate the neural correlates of a reduced awareness in this specific domain in twenty-three consecutive behavioural-variant frontotemporal dementia patients. Gray matter volume changes associated with a reduced awareness for the instrumental domain, assessed using a validated caregiver-patient discrepancy questionnaire, were examined. Interestingly, we found disabilities in instrumental daily living activities and a reduced awareness of these to be related to medial prefrontal cortex atrophy, where the mid-cingulate cortices, dorsal anterior insula and cuneous play an important role. Importantly, if the executive system does not function correctly, the comparator mechanism of action self-monitoring does not detect mismatches between the current and previous performance states stored in the personal database, and produces a reduced awareness for the instrumental domain.

    Objective The aim of our study was to evaluate sensory integration and activities of daily living in children with developmental coordination disorder Subjects and methods 37 cases with developmental coordination disorder and 35 healthy age-matched peers were included in this study. Ayres Southern California Sensory Integration Test was used for evaluating the sensory integration and Functional Independence Measure for Children (WeeFIM) was used for evaluating the activities of daily living. Results Significant differences were found in the visual shape perception, position in space, and design copying (p < 0.05). According to the results of somatosensory perception tests, significant differences were found in kinesthesia, manual form perception, finger identification, figure-ground perception, localization of tactile stimuli, double tactile stimuli perception (p < 0.05). Control group was better in motor planning (p < 0.05). Comprehension, expression, social communication, problem solving, and memory skills were significant in favor of the control group (p < 0.05). Graphestesia and self-care domain was found to be correlated (r = 0,491, p = 0.002) between the groups. Discussion Special education and rehabilitation programs including sensory integration therapy and motor performance will increase independence in the activities of daily living in children with developmental coordination disorder.

    Objective To determine whether participants with mild cognitive impairment (MCI) differ from cognitively normal (NC) older adults on traditional and novel informant-based measures of activities of daily living (ADL) and to identify cognitive correlates of ADLs among participants with MCI. Design Cross-sectional. Setting University medical setting. Participants Seventy-seven participants (NC: N = 39; MCI: N = 38), 60 to 90 years old (73.5 ± 6.6 years; 53% female). Measurements Neuropsychological and ADL measures. Methods Neuropsychological tests were administered to NC and MCI participants. Informants completed the Lawton and Brody Instrumental Activities of Daily Living and Physical Self-Maintenance Scale, including instrumental (IADL) and basic ADL (BADL) scales, as well as the Functional Capacities for Activities of Daily Living (FC-ADL), an error-based ADL measure. Results No statistically or clinically significant between-group differences emerged for the BADL or IADL subscales. However, a robust difference was noted for the FC-ADL scale (MCI errors > NC errors; F(1,75) = 13.6, p <0.001; d = 0.84). Among MCI participants, correlations revealed that a measure of verbal learning was the only neuropsychological correlate of FC-ADL total score (r =-0.39, df = 36, p = 0.007). No neuropsychological measures were significantly associated with the IADL or BADL subscale score. Conclusion Traditional measures assessing global ADLs may not be sensitive to early functional changes related to MCI; however, error-based measures may capture the subtle evolving functional decline associated with MCI. Among MCI participants, early functional difficulties are associated with verbal learning performance, possibly secondary to the hallmark cognitive impairment associated with this cohort.

    Though pain in neuromyelitis optica (NMO) has been described in two recent reports, the proportion with true neuropathic pain (NP), its features, impact on activities of daily living (ADL) and quality of life has not been well characterised. A cross-sectional study of 50 NMO patients with transverse myelitis was performed using Douleur Neuropathique 4, Brief Pain Inventory, Extended Disability Status Scale and Short Form 36. NP was identified in 62% of patients. Pain was constant in 68% affecting most ADL. Pain was associated with significant reduction of the SF36 Mental Composite Score. The high prevalence of NP and associated disability necessitates an in-depth enquiry in patients with NMO.

    Resumption of daily living activities is a basic expectation for patients provided with total knee replacements. However, there is a lack of knowledge regarding the impact of different activities on the wear performance. In this study the wear performance under application of different daily activities has been analyzed. In vivo load data for walking, walking downstairs/upstairs, sitting down/standing up, and cycling (50 W & 120 W) has been standardized for wear testing. Wear testing of each activity was carried out on a knee wear simulator. Additionally, ISO walking was tested for reasons of comparison. Wear was assessed gravimetrically and wear particles were analyzed. In vivo walking produced the highest overall wear rates, which were determined to be three times higher than ISO walking. Moderate wear rates were determined for walking upstairs and downstairs. Low wear rates were determined for standing up/sitting down and cycling at power levels of 50 W and 120 W. The largest wear particles were observed for cycling. Walking based on in vivo data has been shown to be the most wear-relevant activity. Highly demanding activities (stair climbing) produced considerably less wear. Taking into account the expected number of loads, low-impact activities like cycling may have a greater impact on articular wear than highly demanding activities.

    Background Charcot–Marie–Tooth 1A (CMT1A) patients show a reduction of spontaneous activities of daily living measured by means of questionnaires or pedometers, which are quite inaccurate compared to recent measurement techniques. Aim The study aimed at quantifying daily living activities in CMT1A patients by means of inertial sensors, which give information not only on the amount but also on the intensity of these activities. Materials and methods Time and count (amount), and velocity and power (intensity) of 24 h daily living activities were measured in eight patients (20–48 years; Barthel >90; Tinetti >20) and eight healthy individuals, matched for age and gender, by means of a wearable inertial sensor device. Results There were no differences between patients and controls in the 24-h distance covered and count of steps. However, count of step climbing and sit to stand were lower in patients than in controls (139.93 ± 141.66 vs. 341.06 ± 164.07 n and 58.23 ± 7.82 vs. 65.81 ± 4.75 n, respectively; P < 0.05) as well as mean daily step-climbing and walking velocities (1.07 ± 0.17 vs. 1.21 ± 0.10 m/sec and 1.16 ± 0.31 vs. 1.87 ± 0.50 m/sec, respectively; P < 0.05). In CMT1A patients there was a positive correlation between strength of the knee extensor muscles and both count of steps climbed (R = 0.80) and sit to stand (R = 0.79). Discussion and conclusion The reduced ability of CMT1A patients to carry out activities at high intensity, which was correlated with strength, suggests that strength training might be a rehabilitation tool for improving the 1 ability to carry out these activities.

    Hand coordination can allow humans to have dexterous control with many degrees of freedom to perform various tasks in daily living. An important contributing factor to this important ability is the complex biomechanical architecture of the human hand. However, drawing a clear functional link between biomechanical architecture and hand coordination is challenging. It is not understood which biomechanical characteristics are responsible for hand coordination and what specific effect each biomechanical characteristic has. To explore this link, we first inspected the characteristics of hand coordination during daily tasks through a statistical analysis of the kinematic data, which were collected from thirty right-handed subjects during a multitude of grasping tasks. Then, the functional link between biomechanical architecture and hand coordination was drawn by establishing the clear corresponding causality between the tendinous connective characteristics of the human hand and the coordinated characteristics during daily grasping activities. The explicit functional link indicates that the biomechanical characteristic of tendinous connective architecture between muscles and articulations is the proper design by the Creator to perform a multitude of daily tasks in a comfortable way. The clear link between the structure and the function of the human hand also suggests that the design of a multifunctional robotic hand should be able to better imitate such basic architecture.

    OBJECTIVES: This paper examines longitudinal data over 6 years to evaluate incidence rates of disability and the pattern of dependency in activities of daily living. METHODS: The Longitudinal Study of Aging (n = 5151) was used to evaluate incidence of disability in activities of daily living; biennial interview data from 1984 through 1990 were used. The median age to disability onset for individual activities was estimated from survival analysis. A prevalent ordering of incident disability was identified from patterns of disability onset within individuals. RESULTS: The progression of incident disability among the elderly supported by longitudinal data, based on both the ordering of median ages to disability onset and patterns of incident disability, was as follows: walking, bathing, transferring, dressing, toileting, feeding. Gender differences were found in disability incidence rates. CONCLUSIONS: This study provides a mathematical picture of physical functioning as people age. These findings, based on longitudinal data, indicate a different hierarchical structure of disability than found in previous reports using cross-sectional data. Furthermore, the study documents gender differences in incident impairment, which indicate that although women outlive men, they spend more time in a disabled state. PMID:9096537

    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.

    The aim of this study was to build an instrument, the numerical activities of daily living (NADL), designed to identify the specific impairments in numerical functions that may cause problems in everyday life. These impairments go beyond what can be inferred from the available scales evaluating activities of daily living in general, and are not adequately captured by measures of the general deterioration of cognitive functions as assessed by standard clinical instruments like the MMSE and MoCA. We assessed a control group (n = 148) and a patient group affected by a wide variety of neurological conditions (n = 175), with NADL along with IADL, MMSE, and MoCA. The NADL battery was found to have satisfactory construct validity and reliability, across a wide age range. This enabled us to calculate appropriate criteria for impairment that took into account age and education. It was found that neurological patients tended to overestimate their abilities as compared to the judgment made by their caregivers, assessed with objective tests of numerical abilities.

    An evaluation method that includes continuous activities in a daily-living environment was developed for Wearable Mobility Monitoring Systems (WMMS) that attempt to recognize user activities. Participants performed a pre-determined set of daily living actions within a continuous test circuit that included mobility activities (walking, standing, sitting, lying, ascending/descending stairs), daily living tasks (combing hair, brushing teeth, preparing food, eating, washing dishes), and subtle environment changes (opening doors, using an elevator, walking on inclines, traversing staircase landings, walking outdoors). To evaluate WMMS performance on this circuit, fifteen able-bodied participants completed the tasks while wearing a smartphone at their right front pelvis. The WMMS application used smartphone accelerometer and gyroscope signals to classify activity states. A gold standard comparison data set was created by video-recording each trial and manually logging activity onset times. Gold standard and WMMS data were analyzed offline. Three classification sets were calculated for each circuit: (i) mobility or immobility, ii) sit, stand, lie, or walking, and (iii) sit, stand, lie, walking, climbing stairs, or small standing movement. Sensitivities, specificities, and F-Scores for activity categorization and changes-of-state were calculated. The mobile versus immobile classification set had a sensitivity of 86.30% ± 7.2% and specificity of 98.96% ± 0.6%, while the second prediction set had a sensitivity of 88.35% ± 7.80% and specificity of 98.51% ± 0.62%. For the third classification set, sensitivity was 84.92% ± 6.38% and specificity was 98.17 ± 0.62. F1 scores for the first, second and third classification sets were 86.17 ± 6.3, 80.19 ± 6.36, and 78.42 ± 5.96, respectively. This demonstrates that WMMS performance depends on the evaluation protocol in addition to the algorithms. The demonstrated protocol can be used and tailored for evaluating human activity

    Background Information and communication technology (ICT) has become an increasingly important part of daily life. The ability to use technology is becoming essential for autonomous functioning in society. Current functional scales for patients with cognitive impairment do not evaluate the use of technology. The objective of this study was to develop and validate a new version of the Activities of Daily Living Questionnaire (ADLQ) that incorporates an ICT subscale. Method A new technology-based subscale was incorporated into the Spanish Version of the ADLQ (SV-ADLQ), entitled The Technology Version of the ADLQ (T-ADLQ). The T-ADLQ was administered to 63 caregivers of dementia patients, 21 proxies of mild cognitive impairment patients and 44 proxies of normal elderly subjects (mean age of the sample ± SD: 73.5 ± 8.30). We analysed the convergent validity, internal consistency, reliability cut-off point, sensitivity and specificity of the T-ADLQ. The results of the T-ADLQ were compared to the SV-ADLQ. Results The T-ADLQ showed significant correlations with the Mini-mental Test (MMSE), the Frontal Assesment Battery (FAB) as well as other measures of functional impairment and dementia severity (MMSE: r = −0.70; FAB: r = −0.65; Functional Assessment Questionnaire: r = 0.77; Instrumental Activities of Daily Living Scale: r = −0.75; Clinical Dementia Rating Scale: r = 0.72; p<0.001). The T-ADLQ showed a good reliability with a relatively high Cronbach’s alpha coefficient (Cronbach’s alpha = 0.861). When considering a functional impairment cut-off point greater than 29.25%, the sensitivity and specificity of the T-ADLQ were 82% and 90%, respectively. The area under the ROC curve (AUC) was 0.937 for the T-ADLQ and 0.932 for the original version of the test. Conclusions The T-ADLQ revealed adequate indicators of validity and reliability for the functional assessment of activities of daily living in dementia patients.

    2016-01-01

    Video-based recognition of activities of daily living (ADLs) is being used in ambient assisted living systems in order to support the independent living of older people. However, current systems based on cameras located in the environment present a number of problems, such as occlusions and a limited field of view. Recently, wearable cameras have begun to be exploited. This paper presents a review of the state of the art of egocentric vision systems for the recognition of ADLs following a hierarchical structure: motion, action and activity levels, where each level provides higher semantic information and involves a longer time frame. The current egocentric vision literature suggests that ADLs recognition is mainly driven by the objects present in the scene, especially those associated with specific tasks. However, although object-based approaches have proven popular, object recognition remains a challenge due to the intra-class variations found in unconstrained scenarios. As a consequence, the performance of current systems is far from satisfactory. PMID:26751452

    OBJECTIVE. The purpose of this study was to investigate the behavioral intention to use (BIU) regarding a virtual system for practicing instrumental activities of daily living (IADLs) among people with stroke. METHOD. Fourteen people who had sustained a stroke used a virtual world–based system over four sessions to participate in virtual occupations of preparing meals and putting away groceries. To investigate intention to use the technology, participants responded to a questionnaire based on the Technology Acceptance Model and were interviewed about the experience. RESULTS. Analysis of questionnaire responses revealed favorable attitudes toward the technology and statistically significant correlations between these attitudes and positive BIU. Analysis of qualitative data revealed four themes to support system use: Use of the affected arm increased, the virtual practice was enjoyable, the technology was user-friendly, and the system reflected real-life activities. CONCLUSION. This study shows that participants reported a positive BIU for the virtual system for practicing IADLs. PMID:25871604

    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.

    Purpose We sought to characterize self-neglect definitively as a geriatric syndrome by identifying an association with functional impairment. Design and Methods We performed a cross-sectional home evaluation of 100 community-living older adults referred by Adult Protective Services for geriatric self-neglect and 100 matched adults from a community geriatrics clinic. We made our assessments by using two manual muscle tests, a timed-gait test, a modified Physical Performance Test (mPPT), and the Kohlman Evaluation of Living Skills (KELS). Results Participants in the self-neglect group had impaired mPPT (p < .077) and KELS (p < .001) scores compared with community-controls. Using analysis of covariance models, we found that self-neglect referral explained a significant proportion of the variance in KELS scores (32%; p < .001) but not in mPPT scores (22%; p = .49). Implications The geriatric syndrome of self-neglect is associated with increased morbidity and mortality and appears to be independently associated with impairments in instrumental activities of daily living. The evaluation and treatment of geriatric self-neglect should be consistent with that of other geriatric syndromes. PMID:18591364

    This study has been carried out to investigate the level of loneliness, determine the level of dependence in the ADL and influential factors in the elderly people. This descriptive, cross-sectional study was conducted in 5 Family Healthcare Centers (FHC) located in central Erzincan, Turkey between March and June 2010. The data of the research was collected using a questionnaire that determined the descriptive and UCLA Loneliness Scale (UCLA-LS). Mean score of the UCLA-LS was determined as 51.59 ± 4.44. It was determined that 2% of the elderly ADL were completely dependent, 14.5% were semi-dependent. Factors such as being old, a widow/divorced, having a lower level of education and/or income, living alone, having a chronic disease, poor self-perceived health, lack of visits by relatives or acquaintances, dissatisfaction with the place of living, and being fully dependent while performing daily activities were determined as factors which increased the level of loneliness. Furthermore, factors such as being old, a female, a widow/divorced, living together with a daughter/son, having a chronic disease and poor self-perceived health were found to be influential in dependency. Elderly people who are alone and dependent in fulfilling their ADL should be monitored more closely. PMID:21514680

Eleven common activities of daily living were recorded on a scale rated from 0 to 10. Thirty-one patients (23 women and 8 men) who had exhibited facial pain and/or headache for a duration of at least one year participated. Test-retest coefficients of reliability for the patients' assessment of pain and discomfort on two different occasions two weeks apart were high and varied (with the exception of one question) between r = 0.67 and r = 0.92. The correlations between the patients' own estimations and that which one member of the family made were high and varied (with the exception of one question) between r = 0.78 and r = 0.92.

    Mild impairment in activities of daily living (ADL) can occur in Mild Cognitive Impairment (MCI), but the nature and extent of these difficulties need to be further explored. The Canadian occupational performance measure (COPM) is one of the few individualized scales designed to identify self-perceived difficulties in ADL. The present study investigated impairments in ADL using the COPM in elderly with MCI. A total of 58 MCI patients were submitted to the COPM for studies of its validity and reliability. The COPM proved a valid and consistent instrument for evaluating ADL in elderly MCI patients. A total of 74.6% of the MCI patients reported difficulties in ADL. Of these problems, 41.2% involved self-care, 31.4% productivity and 27.4% leisure. This data further corroborates recent reports of possible functional impairment in complex ADL in MCI.

    Objective To investigate the relationship between grip and pinch strength and independence in activities of daily living (ADL) in stroke patients. Methods Medical records of 577 stroke patients from January 2010 to February 2013 were retrospectively reviewed. Patients' grip and pinch strength of both hemiplegic and non-hemiplegic hands and the Korean version of Modified Barthel Index (K-MBI) score were collected. These patients were divided into three groups: group A (onset duration: ≤3 months), group B (onset duration: >3 months and <2 years), and group C (onset duration: ≥2 years). The correlation between grip and pinch strength and the K-MBI score was analyzed. Results In group A (95 patients), the K-MBI score was significantly (p<0.05) correlated with the grip and pinch strength of both hands in patients with right hemiplegia. Significant (p<0.05) correlation between the K-MBI score and the grip and pinch strength of the hemiplegic hand was shown in patients with left hemiplegia. In group B (69 patients) and group C (73 patients), the K-MBI score was significantly (p<0.05) correlated with the grip and pinch strength of the hemiplegic hand. Conclusion Stroke patients in subacute stage mainly performed activities of daily living using their dominant hand. However, independence in ADL was associated with the strength of the affected dominant hand. For stroke patients in chronic and late chronic stages, their hand power of the affected hand was associated with independence in ADL regardless whether the dominant hand was affected. PMID:26605173

    Background Population-based data examining the relationship between social participation (SP) and instrumental activities of daily living (IADL) are scarce. This study examined the cross-sectional relationship between SP and IADL in community-dwelling elderly persons. Methods Self-administered questionnaires were mailed to 23 710 residents aged ≥65 years in Nara, Japan (response rate: 74.2%). Data from 14 956 respondents (6935 males and 8021 females) without dependency in basic activities of daily living (ADL) were analyzed. The number, type, and frequency of participation in social groups (SGs) were used to measure SP. SGs included volunteer groups, sports groups, hobby groups, senior citizens’ clubs, neighborhood community associations, and cultural groups. IADL was evaluated using the Tokyo Metropolitan Institute of Gerontology Index of Competence. Logistic regression models stratified by gender were used. Results After adjustment for putative confounding factors, including demographics, health status, life-style habits, ADL, depression, cognitive function, social networks, social support, and social roles, participation in various SGs among both genders was inversely associated with poor IADL, showing a significant dose-response relationship between an increasing number of SGs and a lower proportion of those with poor IADL (P for trend <0.001). A significant inverse association between frequent participation and poor IADL was observed for all types of SGs among females, whereas the association was limited to sports groups and senior citizens’ clubs among males. Conclusions Our results show that participation in a variety of SGs is associated with independent IADL among the community-dwelling elderly, regardless of gender. However, the beneficial effects of frequent participation on IADL may be stronger for females than for males. PMID:27180933

    The aim of the present study was to determine how women living in St Petersburg, Russia, who have had a mild stroke, describe their performance in activities of daily living (ADL) and to elicit possible causes of their occupational dysfunction. Thirty-six women who had experienced a mild stroke and been referred to a rehabilitation centre participated in the study. Data collection was conducted through interviews, including the 'ADL Staircase' and a modified 'Frenchay Activities Index for Stroke Patients'. Additional data were collected through field notes and information from team members and relatives. The results showed that women who have had a mild stroke and ADL limitations experience occupational dysfunction in ADL that is most often caused by a combination of overprotection from relatives, the women's own feelings of anxiety and insecurity, and an overemphasizing of their disability. The results are limited, based on the small sample and restricted geographic area. There is a need to further investigate how individuals who have had a mild stroke can be physically and socially rehabilitated and reintegrated into the community in countries with developing economies such as Russia.

    In the past decade, several arm rehabilitation robots have been developed to assist neurological patients during therapy. Early devices were limited in their number of degrees of freedom and range of motion, whereas newer robots such as the ARMin robot can support the entire arm. Often, these devices are combined with virtual environments to integrate motivating game-like scenarios. Several studies have shown a positive effect of game-playing on therapy outcome by increasing motivation. In addition, we assume that practicing highly functional movements can further enhance therapy outcome by facilitating the transfer of motor abilities acquired in therapy to daily life. Therefore, we present a rehabilitation system that enables the training of activities of daily living (ADL) with the support of an assistive robot. Important ADL tasks have been identified and implemented in a virtual environment. A patient-cooperative control strategy with adaptable freedom in timing and space was developed to assist the patient during the task. The technical feasibility and usability of the system was evaluated with seven healthy subjects and three chronic stroke patients.

    Detailed knowledge about loading of the knee joint is essential for preclinical testing of implants, validation of musculoskeletal models and biomechanical understanding of the knee joint. The contact forces and moments acting on the tibial component were therefore measured in 5 subjects in vivo by an instrumented knee implant during various activities of daily living. Average peak resultant forces, in percent of body weight, were highest during stair descending (346% BW), followed by stair ascending (316% BW), level walking (261% BW), one legged stance (259% BW), knee bending (253% BW), standing up (246% BW), sitting down (225% BW) and two legged stance (107% BW). Peak shear forces were about 10-20 times smaller than the axial force. Resultant forces acted almost vertically on the tibial plateau even during high flexion. Highest moments acted in the frontal plane with a typical peak to peak range -2.91% BWm (adduction moment) to 1.61% BWm (abduction moment) throughout all activities. Peak flexion/extension moments ranged between -0.44% BWm (extension moment) and 3.16% BWm (flexion moment). Peak external/internal torques lay between -1.1% BWm (internal torque) and 0.53% BWm (external torque). The knee joint is highly loaded during daily life. In general, resultant contact forces during dynamic activities were lower than the ones predicted by many mathematical models, but lay in a similar range as measured in vivo by others. Some of the observed load components were much higher than those currently applied when testing knee implants.

    This study was undertaken to investigate several factors influencing standing balance, activity of daily living and ambulation in hemiplegic patients after cerebro-vascular diseases. A statistical analysis of 121 hemiplegic patients with unilateral supratentorial lesions showed that age, severity of muscle weakness of involved or uninvolved extremities, unilateral spatial neglect and the sense of toe position had influence on standing balance, activity of daily living or ambulation. The patients were divided into five groups based on the degree of unilateral spatial neglect, evaluated by their copies of two daisies who omitted more than three quarters, three quarters, half, one quarter and none of the figures were defined as the USN-4, USN-3, USN-2, USN-1 and no involvement groups, respectively. Those who belonged to the USN-2 group had significantly lower scores for activity of daily living than those who belonged to the no involvement group. In the USN-2 group, 7 of the 8 patients could not keep standing for 50 seconds, while in the no involvement group, this was the case in only 1 of the 15 patients. Activity of daily living scores or sway area during standing showed no statistically significant differences between the USN-1 and no involvement groups. These results suggested that severe or moderate unilateral spatial neglect is one of the most important factors influencing standing balance and activity of daily living. PMID:1614008

    The purpose of this study was to examine the validity of treadmill-based equations of two commonly used uniaxial accelerometers to estimate energy expenditure (EE) during activities of daily living in children. Twelve subjects with mean (SD) age11.4 (0.4) years engaged in a choreographed routine consisting of three activities (sweeping, bowling, and basketball) of 4min duration while wearing a Manufacturing Technology, Inc. (MTI) accelerometer, Caltrac accelerometer, and a portable gas analyzer (Cosmed K4b(2)). The equations of Trost et al. and Sallis et al. were used to convert activity counts to estimations of EE for the MTI and Caltrac, respectively. Correlation coefficients between Caltrac predictions of EE and measured EE from indirect calorimetry ranged from r=0.22 to 0.72 for individual activities. Correlations between MTI EE predictions and indirect calorimetry ranged from r=0.50 to 0.68 for individual activities. When the activities were pooled the correlations between EE from uniaxial accelerometers and EE from indirect calorimetry were moderately strong (MTI, r=0.78 and Caltrac, r=0.82). Inter-accelerometer (counts min(-1)) correlations were 0.08, -0.54, 0.63, and 0.79 for sweeping, bowling, basketball, and pooled data, respectively. The overall mean difference, or bias, and 95% confidence intervals (CI) for each uniaxial accelerometer compared to indirect calorimetry were as follows: Caltrac, bias = 2.80 (2.36, 3.24) kcal min(-1); MTI, bias = 0.88 (0.23, 1.53) kcal min(-1). Both accelerometers significantly underestimated measured EE ( P<0.05). Uniaxial accelerometers provide potential for the measurement of physical activity (PA) and EE in children. Future studies refining accelerometry predictions of PA and EE are warranted.

    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 To investigate the energy expenditure (EE) of Korean young adults based on activities refined to a deskbound lifestyle. Methods Sixty-four healthy office workers aged between 25 and 46 years participated in this study. EE was expressed as metabolic equivalent of task (MET). Participants were evaluated in terms of their EE during physical activities of sleeping (n=22), typing (n=37), folding laundry (n=34), dishwashing (n=32), studying (n=18), mopping (n=35), walking (n=33), stair climbing (n=23), and running (n=29). Volume of oxygen consumption was measured by indirect calorimetry K4b2 (COSMED). The results were compared to the established Compendium MET. Results The MET of activities were: sleeping, 1.24±0.43; typing, 1.35±0.25; folding laundry, 1.58±0.51; dishwashing, 2.20±0.51; studying, 2.11±0.90; mopping, 2.72±0.69; walking at 4 km/hr, 3.48±0.65; stair climbing of five stories, 6.18±1.08; and running at 8 km/hr, 7.57±0.57. The values of typing and mopping were similar to those in the Compendium, whereas those of sleeping, folding laundry, dishwashing, studying, walking, stair climbing and running were different. Conclusion To our knowledge, this estimation of EE in MET during activities of daily living is the first data of young adults in Korea. These data could be used as a reference to modify the guidelines of physical activities for the age group examined in this study. PMID:27606280

    Measurements of shoulder kinematics during activities of daily living (ADL) can be used to evaluate patient function before and after treatment and help define device testing conditions. The purpose of this study was to demonstrate the feasibility of using wearable inertial measurement units (IMUs) to track shoulder joint angles while performing actual ADLs outside of laboratory simulations. IMU data of 5 subjects with normal shoulders was collected for 4h at the subjects' workplace and up to 4h off-work. An Unscented Kalman Filter (UKF) enhanced with gyroscope bias modeling and zero velocity updates demonstrated an accuracy of about 2° and was used to estimate relative upper arm angles from the IMU data. The overall averaged 95th percentile angles were: flexion 128.8°, abduction 128.4°, and external rotation 69.5°. These peaks angles are similar to other investigator's reports using laboratory simulations of ADLs measured with optical and electromagnetic technologies. Additionally, with a Fourier transform the 50th percentile frequency was determined and used to extrapolate the typical number of arm cycles in a 10year period to be 649,000. Application of the UKF with the additional drift correction made substantial improvements in shoulder tracking performance and this feasibility data suggests that IMUs with the UKF are suitable for extended use outside of laboratory settings. The data provides a novel description of arm motion during ADLs including an estimate for the 10 year cycle count of upper arm motion. PMID:27371783

    Public datasets played a key role in the increasing level of interest that vision-based human action recognition has attracted in last years. While the production of such datasets has been influenced by the variability introduced by various actors performing the actions, the different modalities of interactions with the environment introduced by the variation of the scenes around the actors has been scarcely took into account. As a consequence, public datasets do not provide a proper test-bed for recognition algorithms that aim at achieving high accuracy, irrespective of the environment where actions are performed. This is all the more so, when systems are designed to recognize activities of daily living (ADL), which are characterized by a high level of human-environment interaction. For that reason, we present in this manuscript the MEA dataset, a new multi-environment ADL dataset, which permitted us to show how the change of scenario can affect the performances of state-of-the-art approaches for action recognition.

    ABSTRACT The purposes of this study were to compare dexterity, visual perception, and abilities to carry out activities of daily living (ADL) in persons with different multiple sclerosis (MS) subtypes and to determine what relationships exist between the three variables. Fifty-six persons with MS were administered tests of dexterity, visual perception, and ADL ability. Demographic variables and scores on Kurtzke's Expanded Disability Status Scale were also collected. Scores from the chronic-progressive group were significantly higher than those of the benign and progressive-relapsing groups for the Nine-Hole Peg Test-Left Hand, Grooved Peg Test, and Functional Status Index (except Functional Status Index-Pain). There were no differences between the MS groups for any demographic variables except on the Expanded Disability Status Scale. Visual perception did not correlate with dexterity or ADL ability, and only dexterity scores for the left hand correlated with ADL ability. Persons with the severer subtype of MS were significantly impaired compared with the least severe group for dexterity and ADL ability. Decreased dexterity was associated with needing more assistance and having more perceived difficulty with ADL.

    Objective To examine whether disaggregated activities of daily living (ADL) limitations better predict the risk of nursing home admission compared to conventionally used ADL disability counts. Data Sources We used panel data from the Health and Retirement Study (HRS) for years 1998–2010. The HRS is a nationally representative survey of adults older than 50 years (n = 18,801). Study Design We fitted Cox regressions in a continuous time survival model with age at first nursing home admission as the outcome. Time-varying ADL disability types were the key explanatory variables. Principal Findings Of the six ADL limitations, bathing difficulty emerged as the strongest predictor of subsequent nursing home placement across cohorts. Eating and dressing limitations were also influential in driving admissions among more recent cohorts. Using simple ADL counts for analysis yielded similar adjusted R2s; however, the amount of explained variance doubled when we allowed the ADL disability measures to time-vary rather than remain static. Conclusions Looking beyond simple ADL counts can provide health professionals insights into which specific disability types trigger long-term nursing home use. Functional disabilities measured closer in time carry more prognostic power than static measures. PMID:25256014

    The purpose of this study is to clarify the activities of daily living and behaviour disturbances related to inpatients and outpatients with dementia experiencing falls. Patients diagnosed with dementia belonging to 18 facilities which consented to the study were subjected. The study involved "whether or not the patient has fallen in the past 12 months", "Barthel Index (B.I)", and "Dementia Behaviour Disturbance Scale (DBD)" and other data from 325 people in 18 facilities who had been diagnosed with dementia. The ratio of subjects who had fallen to those who had not was 113:212. The results of multiple logistic regression analysis showed that the study items related to falls including the DBD item of "making unwarranted accusations" had an OR = 1.445, 95% CI (1.133-1.843), the DBD item of "refusing to eat" had an OR = 0.699, 95% CI (0.521- 0.938), the B.I item of "feeding" had OR = 1.115, 95% CI (1.032-1.204) and the B.I item of "bathing" had OR = 0.782, 95% CI (0.671-0.912). Integral characteristics of dementia patients who have fallen are assumed to be making unwarranted accusations, having a low rate of refusing to eat, being able to eat alone and requiring attention when bathing.

    OBJECTIVE: To describe the prevalence of headache and its interference in the activities of daily living (ADL) in female adolescent students. METHODS: This descriptive cross-sectional study enrolled 228 female adolescents from a public school in the city of Petrolina, Pernambuco, Northeast Brazil, aged ten to 19 years. A self-administered structured questionnaire about socio-demographic characteristics, occurrence of headache and its characteristics was employed. Headaches were classified according to the International Headache Society criteria. The chi-square test was used to verify possible associations, being significant p<0.05. RESULTS: After the exclusion of 24 questionnaires that did not met the inclusion criteria, 204 questionnaires were analyzed. The mean age of the adolescents was 14.0±1.4 years. The prevalence of headache was 87.7%. Of the adolescents with headache, 0.5% presented migraine without pure menstrual aura; 6.7%, migraine without aura related to menstruation; 1.6%, non-menstrual migraine without aura; 11.7%, tension-type headache and 79.3%, other headaches. Significant associations were found between pain intensity and the following variables: absenteeism (p=0.001); interference in ADL (p<0.001); medication use (p<0.001); age (p=0.045) and seek for medical care (p<0.022). CONCLUSIONS: The prevalence of headache in female adolescents observed in this study was high, with a negative impact in ADL and school attendance. PMID:25119759

    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.

    Background It is today widely accepted that participation in social activities contributes towards successful ageing whilst, at the same time, maintaining independence in the activities of daily living (ADLs) is the sine qua non for achieving that end. This study looks at people aged 65 and over living in an urban area in Spain who retain the ability to attend Social Centres providing recreational facilities. The aim of this paper is to quantify independence and identify the risk factors involved in its deterioration. Methods The sample size was calculated using the equation for proportions in finite populations based on a random proportional sample type, absolute error (e) = 0.05, α = 0.05, β = 0.1, p = q = 0.5. Two-stage sampling was used. In the first place, the population was stratified by residence and a Social Centre was randomly chosen for each district. In the second stage, individuals were selected in a simple random sample without replacement in proportion to the number of members at each social centre. A multivariate logistical regression analysis takes functional ADL capacity as the dependent variable. The choice of predictive variables was made using a bivariate correlation matrix. Among the estimators obtained, Nagelkerke's R2 coefficient, and the Odds ratio (CI 95%) were considered. Sensitivity and 1-specificity were adopted to present the results in graphic form. Results Out of this sample, 63.7% were fully capable of carrying out ADLs, while the main factors contributing to deterioration, identified on the basis of a logistic regression model, are in order of importance, poor physical health, poor mental health, age (above 75 years) and gender (female). The model employed has a predictive value of 88% and 92% (depending on the age range considered) with regard to the independence in ADLs. Conclusion A review of the few Spanish works using similar methodology shows that the percentage of non-institutionalised persons who are independent enough to

    OBJECTIVES. This study investigated the role of low normal cognitive function in the subsequent loss of independence in activities of daily living. METHODS. Of the 678 elderly nuns who-completed cognitive and physical function assessments in 1992/93, 575 were reassessed in 1993/94. Mini-Mental State Examination scores were divided into three categories and related to loss of independence in six activities of daily living. RESULTS. Participants with low normal cognitive function at first assessment had twice the risk of losing independence in three activities of daily living by second assessment relative to those with high normal cognitive function. This relationship was largely due to a progression from low normal cognitive function at first assessment to impaired cognitive function at second assessment and was associated with an elevated risk of losing independence in the six activities. CONCLUSIONS. Progression from low normal to impaired cognitive function was associated with loss of independence in activities of daily living. Thus low normal cognitive function could be viewed as an early warning of impending cognitive impairment and loss of physical function. PMID:8561244

    [Purpose] The objective of this study was to investigate the effects of mirror therapy combined with exercise tasks on the function of the upper limbs and activities of daily living. [Subjects and Methods] Twenty-five stroke patients who were receiving physical therapy at K Hospital in Gyeonggi-do, South Korea, were classified into a mirror therapy group (n=12) and a conventional therapy group (n=13). The therapies were applied for 30 minutes per day, five times per week, for a total of four weeks. Upper limb function was measured with the Action Research Arm test, the Fugl-Meyer Assessment, and the Box and Block test, and activities of daily living were measured with the Functional Independence Measure. A paired test was performed to compare the intragroup differences between before training and after four weeks of therapy, and an independent t-test was performed to compare the differences between the two groups before and after four weeks of therapy. [Results] In the intragroup comparison, both groups showed significant differences between measurements taken before and after four weeks of therapy. In the intergroup comparison, the mirror therapy group showed significant improvements compared with the conventional therapy group, both in upper limb function and activities of daily living.

    [Purpose] The trunk muscles frequently become weak after stroke, thus impacting overall activities of daily living. However, activities of daily living items closely related with trunk strength remain unclear. This study aimed to clarify the influence of trunk muscle weakness on activities of daily living items. [Subjects] The subjects were 24 stroke patients who fulfilled the following inclusion criteria: first stroke and the absence of severe paralysis, marked cognitive function deterioration, unilateral spatial neglect or apathy. [Methods] According to abdominal strength, the 24 patients were divided into a nonweakness group and a weakness group. For the assessment, we used the stroke impairment assessment set, the Berg balance scale, a simple test for evaluating hand function, grip strength, and functional independence measure scale scores and the results were compared between the groups. [Results] The Berg balance scale score and scores for dressing, toilet use, transfer to bed, and walk items of the functional independence measure were significantly lower in the weakness group than in the nonweakness group. [Conclusion] Our results suggest that weakness of the abdominal muscles adversely impacts the balance of patients with mild stroke as well as their ability to dress, use a toilet, transfer, and walk. Trunk training, including abdominal muscle exercises, can effectively improve the performance of these activities of daily living items.

    [Purpose] There have been no investigations into the improvement of activities of daily living among patients suffering from post-stroke depression on admission to convalescent rehabilitation wards in Japan. This study aimed to assess the improvement of activities in daily living in patients with or without post-stroke depression at the time of admission to a convalescent rehabilitation ward. [Subjects and Methods] This retrospective study included 108 stroke patients divided into two groups according to their Geriatric Depression Scale 15-item short form scores. Activities of daily living were assessed using the Functional Independence Measure. The degree of improvement on the Functional Independence Measure was defined as the difference between scores on admission and at discharge. [Results] The Functional Independence Measure gain score was significantly different from the Functional Independence Measure total score. There was a significant interaction between time period and post-stroke depression factors for the Functional Independence Measure total score. A multiple regression analysis revealed a significant association between Geriatric Depression Scale score and Functional Independence Measure total score. [Conclusion] The present study suggests that post-stroke depression has a negative impact on recovery of activities of daily living and on rehabilitation outcomes in a convalescent rehabilitation ward setting.

    The purpose of this study was to examine the effects of mirror therapy on upper-extremity function and activities of daily living in chronic stroke patients. [Subjects and Methods] Fifteen subjects were each assigned to a mirror therapy group and a sham therapy group. The Fugl-Meyer Motor Function Assessment and the Box and Block Test were performed to compare paretic upper-extremity function and hand coordination abilities. The functional independence measurement was conducted to compare abilities to perform activities of daily living. [Results] Paretic upper-extremity function and hand coordination abilities were significantly different between the mirror therapy and sham therapy groups. Intervention in the mirror therapy group was more effective than in the sham therapy group for improving the ability to perform activities of daily living. Self-care showed statistically significant differences between the two groups. [Conclusion] Mirror therapy is effective in improving paretic upper-extremity function and activities of daily living in chronic stroke patients. PMID:26180297

    Inverse dynamics based simulations on musculoskeletal models is a commonly used method for the analysis of human movement. Due to inaccuracies in the kinematic and force plate data, and a mismatch between the model and the subject, the equations of motion are violated when solving the inverse dynamics problem. As a result, dynamic inconsistency will exist and lead to residual forces and moments. In this study, we present and evaluate a computational method to perform inverse dynamics-based simulations without force plates, which both improves the dynamic consistency as well as removes the model׳s dependency on measured external forces. Using the equations of motion and a scaled musculoskeletal model, the ground reaction forces and moments (GRF&Ms) are derived from three-dimensional full-body motion. The method entails a dynamic contact model and optimization techniques to solve the indeterminacy problem during a double contact phase and, in contrast to previously proposed techniques, does not require training or empirical data. The method was applied to nine healthy subjects performing several Activities of Daily Living (ADLs) and evaluated with simultaneously measured force plate data. Except for the transverse ground reaction moment, no significant differences (P>0.05) were found between the mean predicted and measured GRF&Ms for almost all ADLs. The mean residual forces and moments, however, were significantly reduced (P>0.05) in almost all ADLs using our method compared to conventional inverse dynamic simulations. Hence, the proposed method may be used instead of raw force plate data in human movement analysis using inverse dynamics.

    Age-related deficiencies in thermoregulation diminish the capacity to defend against heat loss under conditions often encountered during activities of daily living (ADL). A potential consequence of these deficiencies is that elderly individuals could have colder lower limbs, which would exacerbate the age-related decline in plantarflexor contractile properties and compromise recovery from a tripping incident. Moreover, a common self-perception among the elderly is that their limbs are cold. However, this impression has never been documented, especially under ADL conditions. Our objective was to test the hypothesis that elderly individuals have lower plantarflexor temperatures than their younger counterparts. Skin temperatures above the plantarflexors of elderly and young individuals were continuously recorded during ADL in the winter months and compared under three conditions: quiescent indoor temperature, during a cold challenge, and the recovery period subsequent to the cold challenge. For quiescent indoor periods, differences in skin temperature between the two groups were not statistically significant. During cold exposures, both age and exposure duration were statistically significant factors related to the decrease in skin temperature, with the elderly group maintaining warmer temperatures. In the recovery period following short duration cold exposures, a statistically significant difference between the two groups for the decrease in skin temperature persisted for the first 9min of recovery. The results do not support the hypothesis that the lower limbs of elderly participants are colder. Higher limb temperatures observed in elderly participants were consistent with previous studies of age-related thermoregulatory changes, indicating that deficiencies in vasoconstriction are persistent in ADL.

    , 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. Results 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). Conclusions 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.

    In individuals with multiple sclerosis (MS) spasticity, associated symptoms such as spasms, pain, mobility restrictions and sleep disturbances can interfere with the ability to perform activities of daily living and reduce quality of life (QoL). Recent cross-sectional studies from Europe have confirmed that advancing severity of MS spasticity correlates directly with worsening QoL. The treatment effect of Sativex(®) (GW Pharmaceuticals PLC, Porton Down, UK; Laboratorios Almirall, SA, Barcelona, Spain) on QoL has been evaluated in randomized controlled trials, observational studies conducted under everyday clinical practice conditions and a survey in long-term users. Symptomatic relief of MS spasticity in responders to Sativex was associated with quantifiable improvements in QoL and activities of daily living that were maintained over time. Benefits were perceived by both patients and caregivers. PMID:25275238

    With recent advances in microprocessor chip technology, wireless communication, and biomedical engineering it is possible to develop miniaturized ubiquitous health monitoring devices that are capable of recording physiological and movement signals during daily life activities. The aim of the research is to implement and test the prototype of health monitoring system. The system consists of the body central unit with Bluetooth module and wearable sensors: the custom-designed ECG sensor, the temperature sensor, the skin humidity sensor and accelerometers placed on the human body or integrated with clothes and a network gateway to forward data to a remote medical server. The system includes custom-designed transmission protocol and remote web-based graphical user interface for remote real time data analysis. Experimental results for a group of humans who performed various activities (eg. working, running, etc.) showed maximum 5% absolute error compared to certified medical devices. The results are promising and indicate that developed wireless wearable monitoring system faces challenges of multi-sensor human health monitoring during performing daily activities and opens new opportunities in developing novel healthcare services.

    Objective This paper describes the 2001–2012 progression of limitations in daily activities in the Mexican elderly population aged 60 or older and identifies how sociodemographic and health factors affect these progressions. Materials and methods 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 Difficulty in getting dressed is the activity that has the highest prevalence in all three waves for both genders. In the 11-year transition, 42.8% of the respondents with no limitations in 2001 reported no limitations in 2012. In contrast, 60.8% of those who reported three or more limitations in 2001 had died by 2012. Conclusions With the rapid aging of the Mexican population, the knowledge of patterns of deterioration of functional limitations will prove useful for future public health policies. PMID:26172235

    Reliance on others for help with food-related activities (grocery shopping and meal preparation) [FADL] can influence food intake and can be considered part of the concept of food security for older adults. Data collected from 193 community-living seniors identified that 29.5% of these seniors required help with these activities. Covariates independently associated with FADL were: muscle strength/size, gender, avoidance of activities due to a fear of falling and occurrence of functionally limiting diagnoses. Mediation analysis identified variables that explain the "how and why" of the association between FADL and food intake. Mediators included informal supports, frequency of informal support, perceived health status, and number of medications. By specifically analyzing covariates and mediators of reliance for FADL, there is further understanding of the relationship between this reliance and food intake in older adults. PMID:16891262

    Psychosocial problems are frequent among patients with psoriasis. The aim of this study was to analyse the prevalence of some specific psychosocial issues. These were evaluated in 936 patients using the emotions and functioning scales of the Skindex-29 questionnaire. The problems most frequently experienced were: shame, anger, worry, difficulties in daily activities and social life. All problems were associated with the severity of psoriasis and with depression or anxiety. Shame, worry and annoyance were more frequent in women than in men, and shame and anger were associated with a low level of education. Impairment in work/hobbies was significantly higher in patients with palmoplantar psoriasis and those with arthro-pathic psoriasis. In conclusion, clinicians could gain important insights about their patients by looking at the single items of a quality of life instrument, to identify patients with high levels of emotional and social problems, in order to improve quality of care.

    Research on daily living activities and employment levels of adults with autism spectrum disorders (ASD) in Taiwan is limited. The aims of the study were to investigate outcomes related to functional independence and employment among people with ASD in Taiwan. We investigated the daily living activities and the employment status of 81 adults (age range, 18-48 years; mean age, 22.8 years) with ASD in southern Taiwan. Most (85.2%) participants with ASD were men, and all lived with their caregivers or guardians. Primary caregivers or guardians completed a self-administered, written questionnaire. More than three-quarters (80.2%) of the participants with ASD could independently take care of themselves. Instrumental activities of daily living they most frequently engaged in included walking outside for more than 15 min (88.9%), light housework (85.2%), and local shopping (80.2%). Only 11 (13.6%) of the participants with ASD were employed [five (6.2%) worked more than 20 h/week] and four (4.9%) were attending school. Types of occupation consisted of serving food and beverages, baking, and cleaning. Most (81.5%) of the participants with ASD were unemployed, stayed at home, and were cared for by family members. The results of this study provide information to support the design of adequate interventions to meet the needs of adults with ASD, particularly those in Taiwan. It is important to develop adequate interventions to facilitate the functional independence of this population. Future research using larger study populations with a comparison group is needed.

    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

Reminiscence therapy sessions were held with groups consists of 4-5 patients, once a week with 30-35 minute duration for 12 weeks. Standardized Mini Mental Test was used in sample selection. Patients were listed through their mini mental test scores, and randomized as odd numbers to control group and even numbers to intervention group. Data were collected with forms developed by researcher 'Data Sheet' and 'Activities of Daily Living Follow-up Form' as well as scales 'Standardized Mini Mental Test' and 'Geriatric Depression Scale'. Chi-square, Mann Whitney-U test, variance analyses in repeated measures and Bonferroni tests were used for analysis. The increase in mean Standardized Mini Mental Test score and the decrease in mean Geriatric Depression Scale score of the individuals in the intervention group compared to the control group at the end of the reminiscence therapy was statistically significant (P < 0.05). At the end of reminiscence therapy sessions, increase in cognition and decrease in depression were found statistically significant in intervention group.

    This retrospective study investigated the relationship between self-reports and caregiver perceptions of patients' depressive symptoms and the respective ability of these reports to predict instrumental activities of daily living (IADLs) beyond what is accounted for by cognitive abilities in 71 patients with mild Alzheimer disease. Patients completed the Geriatric Depression Scale-Short Form, and caregivers completed the Behavior Rating Scale for Dementia assessing their perception of patients' depressive symptoms. Caregivers also completed IADL items from the Alzheimer's Disease Cooperative Study Activities of Daily Living Inventory. Cognitive measures included the Mini-Mental State Examination, Logical Memory from the Wechsler Memory Scale III, and Trail Making Test, Part B. The relationship between self-reported depressive symptoms and caregiver report of patients' depressive symptoms showed a trend toward significance (r = .22, P = .06). Measures of depressive symptoms significantly predicted 12.5% of the variance in IADLs performance, beyond that accounted for by patient demographics and cognitive functioning. Interestingly, patients' reports, rather than caregivers', were particularly useful in this prediction. PMID:26071443

    OBJECTIVE: To evaluate the impact of asthma on activities of daily living and on health status in patients with controlled, partially controlled, or uncontrolled asthma in Brazil. METHODS: We used data related to 400 patients in four Brazilian cities (São Paulo, Rio de Janeiro, Salvador, and Curitiba), obtained in a survey conducted throughout Latin America in 2011. All study subjects were > 12 years of age and completed a standardized questionnaire in face-to-face interviews. The questions addressed asthma control, hospitalizations, emergency room visits, and school/work absenteeism, as well as the impact of asthma on the quality of life, sleep, and leisure. The level of asthma control was determined in accordance with the Global Initiative for Asthma criteria. RESULTS: Among the 400 respondents, asthma was controlled in 37 (9.3%), partially controlled in 226 (56.5%), and uncontrolled in 137 (34.2%). The numbers of patients with uncontrolled or partially controlled asthma who visited the emergency room, who were hospitalized, and who missed school/work were higher than were those of patients with controlled asthma (p = 0.001, p = 0.05, and p = 0.01, respectively). Among those with uncontrolled asthma, the impact of the disease on activities of daily living, sleep, social activities, and normal physical exertion was greater than it was among those with controlled or partially controlled asthma (p < 0.001). CONCLUSIONS: In Brazil, asthma treatment should be monitored more closely in order to increase treatment adherence and, consequently, the level of asthma control, which can improve patient quality of life and minimize the negative impact of the disease.

    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.

    Study Design Controlled laboratory study. Background The activity of the rotator cuff muscles has not previously been measured with indwelling electromyography (EMG) comparing ambulation and other movements. Knowledge of the relative contribution of these muscles during various tasks may help to guide rehabilitation progression. Objective To measure activity of the rotator cuff muscles and other shoulder muscles during normal ambulation, shirt and sling donning and doffing, and rehabilitation tasks commonly performed after rotator cuff surgery. Methods In 28 volunteers (15 men, 13 women; mean age, 32.2 years), indwelling EMG activity was measured in the supraspinatus, infraspinatus, teres minor, and subscapularis muscles during various tasks; and surface EMG activity was measured in the middle deltoid, biceps, and upper trapezius muscles. Results Using median EMG activity, in general, donning and doffing a shirt or sling recruited the rotator cuff muscles more than the other 7 tasks tested. Self-ranging motion using pulleys, especially in the scapular plane, was also consistently associated with greater recruitment of the shoulder muscles. Pendulum exercises, passive range of motion by a physical therapist, and self-ranging motion with a dowel recruited the shoulder muscles to a lesser extent. Conclusion Our results demonstrate that rehabilitation tasks such as pendulum exercises, passive range of motion by a physical therapist, and self-ranging motion with a dowel show low EMG activity, whereas pulleys in the sagittal plane and scapular plane show greater activity. Scapular plane activity was consistently higher than sagittal plane activity. Of all the tasks assessed, ambulation without a sling and donning and doffing a sling and a shirt consistently showed the highest activity. J Orthop Sports Phys Ther 2016;46(5):375-383.

    [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

    We surveyed 1144 current patients with Minamata disease (MD) aged 40 or over in the Minamata area and the same number of neighbor controls matched with age and sex by questionnarie interview with regard to subjective complaints and activities of daily living (ADL). From analysis of subjective complaints, it was found that MD patients had significantly higher rates of all complaints than controls (P < 0.05). Multivariate analysis showed that subjective complaints in controls were clearly separated into the following two categories: sensor disturbances and movement nerve disturbances, but all complaints in MD patients formed one cluster. Such variation seemed to be due to methylmercury exposure to the central nervous system. ADL analysis revealed that the difference in the ADL disability between MD patients and controls significantly increased with age (P < 0.05) and that ADL disability in MD patients was aggravated by aging. 25 refs., 4 figs., 5 tabs.

    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

  9. The Effect of Type-2-Diabetes-Related Vascular Endothelial Dysfunction on Skin Physiology and Activities of Daily Living

    PubMed Central

    2011-01-01

    A common factor contributing to organ damage in type 2 diabetes mellitus (T2DM) is impaired tissue blood flow caused by damage to vascular endothelial cells (VECs). Damage can occur even before the clinical diagnosis of diabetes. It can be caused by both a high average blood glucose concentration and/or large daily spikes in blood glucose. While much of the present literature focuses on the damage to VECs and organs from these large glucose excursions, this review will focus on the consequence of this damage, that is, how endothelial cell damage in diabetes affects normal daily activities (e.g., exercise, reaction to typical stimuli) and various treatment modalities (e.g.. contrast baths and electrical stimulation therapy). It is important to understand the effects of VEC damage such as poor skin blood flow, compromised thermoregulation, and altered response to skin pressure in designing diabetes technologies as simple as heating pads and as complex as continuous glucose monitors. At the simplest level, people with diabetes have poor circulation to the skin and other organs. In the skin, even the blood flow response to locally applied pressure, such as during standing, is different than for people who do not have T2DM. Simple weight bearing on the foot can occlude the skin circulation. This makes the skin more susceptible to damage. In addition, endothelial damage has far-reaching effects on the whole body during normal activities of daily living, including an impaired response to local heat, such as hot packs and contrast baths, and higher body temperatures during whole body heating due to impaired blood flow and a reduced ability to sweat. Finally, because of multiple organ damage, people with T2DM have poor balance and gait and impaired exercise performance. PMID:21722580

    The aim of this pilot study was to investigate how sub-acute low-back pain (LBP) patients differed with respect to control in movements and muscle activation during standardized tasks representing daily living activities, and explore relationships between cognition and measured motor performance. Linear and nonlinear parameters were computed from kinetics, kinematics and muscle activity recorded for 12 sub-acute patients and 12 healthy matched controls during trunk flexion, sit-to-stand from a chair and lifting a box. Cognitive variables were collected to explore relationships with biomechanical parameters. For trunk flexion, left external abdominal oblique muscle activity level was lower for patients compared with controls (p < 0.05), whereas sample entropy (complexity) was higher (p < 0.05). Normalized mutual information was lower for patients compared with controls for left and right erector spinae (p < 0.05). Level of activity of left external abdominal oblique correlated negatively with cognitive ignoring and positively with catastrophizing (p ≤ 0.05), and catastrophizing also correlated positively with functional connectivity of abdominal muscles (p < 0.05). Signs of reorganization in muscle activation pointed towards different synergistic actions in trunk muscles in sub-acute LBP patients compared with controls. The interplay with maladaptive cognition suggested that in the subacute stage of LBP, both biomechanical and cognitive factors should be taken into account. PMID:22995335

    Background Age is an important determinant of outcome in acute myocardial infarction (AMI). However, in clinical settings, there is an occasional mismatch between chronological age and physical age. We evaluated whether activities of daily living (ADL), which reflect physical age, also predict complications and prognosis in elderly patients with AMI. Design Single-center, observational, and retrospective cohort study. Methods Preserved ADL and low ADL were defined according to the scale for independence degree of daily living for the disabled elderly by the Japanese Ministry of Health, Labour, and Welfare. We examined 82 consecutive patients aged ≥75 years with AMI who underwent primary percutaneous coronary intervention. Patients were divided into preserved ADL (n=52; mean age, 81.8±4.8 years; male, 59.6%) and low ADL (n=30; mean age, 85.8±4.7 years; male, 40.0%) groups according to prehospital ADL. Results The prevalence of Killip class II–IV and in-hospital mortality rate were significantly higher with low ADL compared to that with preserved ADL (23.1% vs 60.0%, P=0.0019; 5.8% vs 30.0%, P=0.0068, respectively). Multivariate analysis showed that ADL was an independent predictor of Killip class II–IV and 1-year mortality after adjusting for age, sex, and other possible confounders (odds ratio 5.11, 95% confidence interval [CI] 1.52–17.2, P=0.0083; hazard ratio 4.32, 95% CI 1.31–14.3, P=0.017, respectively). Conclusion Prehospital ADL is a significant predictor of heart failure complications and prognosis in elderly patients with AMI undergoing primary percutaneous coronary intervention, irrespective of age and sex.

    Few studies exist describing unicompartmental osteoarthritic knee kinematics. Moreover, the role of the anterior cruciate ligament (ACL) in the determination of knee kinematics has not been fully described. The objective of the current study was to analyze the in vivo kinematics of knees with medial osteoarthritis (OA) and intact ACL during closed and open chained motion. Eight patients scheduled for UKA diagnosed with primary medial OA underwent knee CT-scans and video-fluoroscopy. Fluoroscopic analysis included stair climbing, chair rising and leg extension. Three-dimensional bone positions were obtained from each image by iterative procedures using a CAD-model-based shape-matching technique. Patterns of axial rotation and anterior-posterior (AP) motion of the medial and lateral femoral condyle were obtained with specific software. The femur reported an overall external rotation relative to the tibia from extension to flexion in all tasks. Average AP translation of the medial femoral condyle were smaller in open-chained tasks than in weight-bearing conditions. Average AP motion of the lateral femoral condyle reported an overall posterior translation with knee flexion. The absent natural "screw-home" mechanism and the lack of medial condyle posterior translation was explained by bone-cartilage defects and meniscal degeneration. Relevant findings were the kinematic pattern differences between weight-bearing and open chained activities, suggesting that in biphasic muscle contraction and unloaded conditions, the function of the cruciate ligaments was not physiological. The kinematics of knees with medial OA and intact ACL differed from healthy knees. PMID:25382361

    [Purpose] The purpose of this study was to investigate the effects of hand strength on upper extremity function and activities of daily living in patients with right hemiplegia, as well as to provide important fundamental data for rehabilitation after stroke. [Subjects and Methods] This study was conducted from May 1 to December 30, 2013, at the Department of Rehabilitation of P Hospital in Seoul and included subjects hospitalized with a diagnosis of stroke. Patients with right hemiplegia were selected, and their hand strength, upper extremity function, and activities of daily living were evaluated. Hand strength was measured by grip, lateral pinch, and three-point pinch strength. [Results] The effects of hand strength on upper extremity function were evaluated. The results showed that all types of hand strength significantly influenced upper extremity function. However, only grip strength influenced activities of daily living. [Conclusion] In rehabilitation of stroke patients, it is necessary to first improve their general physical condition and basic activities of daily living, and then improve hand movement and hand muscle strength for instrumental activities of daily living training, which requires detailed hand movements.

    Functional status is often defined by cumulative scores across indices of independence in performing basic and instrumental activities of daily living (ADL/IADL), but little is known about the unique relationship of each daily activity item with the fall outcome. The purpose of this retrospective study was to examine the level of relative risk for a future fall associated with difficulty with performing various tasks of normal daily functioning among older adults who had fallen at least once in the past 12 months. The sample was comprised of community-dwelling individuals 70 years and older from the 1984–1990 Longitudinal Study of Aging by Kovar, Fitti, and Chyba (1992). Risk analysis was performed on individual items quantifying 6 ADLs and 7 IADLs, as well as 10 items related to mobility limitations. Within a subsample of 1,675 older adults with a history of at least one fall within the past year, the responses of individuals who reported multiple falls were compared to the responses of participants who had a single fall and reported 1) difficulty with walking and/or balance (FRAIL group, n = 413) vs. 2) no difficulty with walking or dizziness (NDW+ND group, n = 415). The items that had the strongest relationships and highest risk ratios for the FRAIL group (which had the highest probabilities for a future fall) included difficulty with: eating (73%); managing money (70%); biting or chewing food (66%); walking a quarter of a mile (65%); using fingers to grasp (65%); and dressing without help (65%). For the NDW+ND group, the most noteworthy items included difficulty with: bathing or showering (79%); managing money (77%); shopping for personal items (75%); walking up 10 steps without rest (72%); difficulty with walking a quarter of a mile (72%); and stooping/crouching/kneeling (70%). These findings suggest that individual items quantifying specific ADLs and IADLs have substantive relationships with the fall outcome among older adults who have difficulty with

    The purpose of the study is to investigate the effects of therapeutic Tai chi (TTC) on the functional fitness status and activities of daily living (ADL) of patients with Parkinson disease (PD). The participants were clinically stable PDs in Hoehn and Yahr stage 1–2. These patients were randomly assigned to either the TTC group (n=11) or the control (CON) group (n=9). The TTC exercised at the clinic 2 times a week and performed home-based activity 1 time per week for 12 weeks. All the PDs were evaluated for functional fitness test and ADL screen before and after the 12-week trial. There was a significant Time × group interaction effect on the arm curl (P<0.01), functional reach (P<0.05), and stand on foot with eyes opened (P<0.05) of the functional fitness as compared to the CON. The results of the functional reach test in the CON worsened significantly during the 12-week intervention in comparison with those of the TTC (P<0.01). Also ADL showed significant changed in TCC (P<0.05). Tai chi training showed good effects on the functional fitness in PDs. This study suggests that further research into the based such as Tai chi intervention must be developed PD’s quality of life in the future. PMID:27807532

    Determining the groups that are most susceptible to developing disability is essential to establishing effective prevention and rehabilitation strategies. The aim of the present study was to determine gender differences in the incidence of disability regarding activities of daily living (ADL) and determinants among elderly residents of Sao Paulo, Brazil. In 2000, 1634 elderly with no difficulties regarding ADL (modified Katz Index) were selected. These activities were reassessed in 2006 and disability was the outcome for the analysis of determinants. The following characteristics were analyzed at baseline: socio-demographic, behavioral, health status, medications, falls, hospitalizations, depressive symptoms, cognition, handgrip, mobility and balance. The incidence density was 42.4/1000 women/year and 17.5/1000 men/year. After adjusting for socioeconomic status and health conditions, women with chronic diseases and social vulnerability continued to have a greater incidence of disability. The following were determinants of the incidence of disability: age and depressive symptoms in both genders; stroke and slowness on the sit-and-stand test among men; and osteoarthritis and sedentary lifestyle among women. Better cognitive performance and handgrip strength were protective factors among men and women, respectively. Adverse clinical and social conditions determine differences between genders regarding the incidence of disability. Decreased mobility and balance and health conditions that affect the central nervous system or lead to impaired cognition disable men more, whereas a sedentary lifestyle, reduction in muscle strength and conditions that affect the osteoarticular system disable women more.

    Purpose of the Study: (a) Identify the prevalence of nursing homes providing Medicare supported restorative care programs and of long stay participants, (b) compare characteristics between restorative care participants and nonparticipants, and (c) assess restorative care’s effect on change in activities of daily living (ADL) dependency. Design and Methods: Longitudinal analysis of Minimum Data Set assessments linked to the 2004 National Nursing Home Survey using a sample of 7,735 residents, age ≥ 65 years living in 1,097 nursing homes for at least 6 months. Receipt of any restorative care was used as a time varying predictor to estimate change in ADL dependency over 18 months using linear mixed models. Results: The sample was 75% female, 89% non-Hispanic White, with a mean age of 85±8, and average length of stay of 3.2±3.4 years. Most nursing homes had restorative care programs (67%), but less than one-third of long-stay residents participated. After controlling for resident and nursing home characteristics, the predicted mean ADL dependency score (range 0–28) at baseline was 18 for restorative care participants and 14 for nonparticipants. Over 18 months, ADL dependency increased 1 point for both participants and nonparticipants (p = .12). Implications: A minority of long-stay residents participated in Medicare supported restorative care programs despite their availability and potential benefits. Even though participants had greater vulnerability for deterioration in physical, mental, and functional health than nonparticipants, both groups had similar rates of ADL decline. Future research is needed to determine if providing restorative care to less dependent long-stay residents is effective. PMID:26055785

    Background The Vestibular Disorders Activities of Daily Living Scale (VADL) is considered an important subjective assessment to evaluate patients suffering from dizziness and imbalance. Although frequently used, its metric characteristics still require further investigation. Objective This paper aims to analyze the psychometric properties of the Brazilian version of the VADL in an elderly population. Method The sample comprises patients (≥65 years old) with chronic dizziness resulting from vestibular disorders. For discriminant analysis, patients were compared to healthy subjects. All subjects answered the VADL-Brazil by interview. To examine the VADL validity, patients filled out the Dizziness Handicap Inventory (DHI) and the ABC scale and were tested on the Dynamic Gait Index (DGI). To evaluate the VADL responsiveness, 20 patients were submitted to rehabilitation. Results Patients (n=140) had a VADL total score of 4.1±1.6 points. Healthy subjects scored significantly less than patients in all the subscales and in the VADL total score. The VADL-Brazil was weakly correlated with the DHI and moderately to the ABC scale and the DGI. Instead of the original 3 subscales, factor analysis resulted in 6 factors. The VADL was capable of detecting changes after rehabilitation, which means that the instrument has responsiveness. Conclusions This study provided more data about the psychometric properties and usefulness of the VADL-Brazil. The use of such a reliable and valid instrument increases the knowledge about disability in patients with vestibular disorders. PMID:24676704

    OBJECTIVE. We investigated differences in observed performance of instrumental activities of daily living (IADLs) and self-reported satisfaction with social role performance between people with amnestic mild cognitive impairment (a-MCI) and age- and gender-matched control participants. METHOD. We measured observed performance of 14 IADLs using the Independence, Safety, and Adequacy domains of the Performance Assessment of Self-Care Skills (PASS) and the Patient-Reported Outcomes Measurement Information Systems (PROMIS) to examine satisfaction with social role performance. RESULTS. Total PASS scores were significantly lower in participants with a-MCI (median = 40.6) than in control participants (median = 44.2; p = .006). Adequacy scores were also significantly lower. No significant differences were found between groups on the PROMIS measures. CONCLUSION. IADL differences between groups were related more to errors in adequacy than to safety and independence. Occupational therapy practitioners can play a key role in the diagnosis and treatment of subtle IADL deficits in people with MCI. PMID:25871600

    The purpose of this study was to determine the degree to which a novel training program based on activities of daily living (ADL) would affect performance of ADLs, as well as the fitness of older adults. Fourteen individuals (mean age 82 years) took part in a 10-week control period followed by a 10-week ADL-based training program. Pre- and posttests included the Physical Performance Test (PPT), the Physical Functional Performance-10 (PFP-10), and the Senior Fitness Test (SFT). After the training period, improvements ranging from 7% to 33% (p<.05) were seen on the PPT and PFP-10 and on three items of the SFT. After conversion to standard scores, the magnitude of change in the PPT and the PFP10 was significantly greater (p<.05) than the magnitude of change in the SFT. These data support the idea that this novel ADL-based training program was able to facilitate improved performance of ADLs, as well as select measures of fitness among older adults.

    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.

    Background/Aims We investigated quantitative/qualitative changes of instrumental activities of daily living (IADL) in people with a Clinical Dementia Rating (CDR) of 0.5. Methods IADLs were evaluated in older residents: CDR of 0 (healthy) and CDR 0.5 (questionable/very mild dementia). The subjects with CDR 0.5 were divided into 2 types: the very mild Alzheimer's disease (vmAD) type and the other type including very mild subcortical vascular dementia. IADLs were evaluated quantitatively using the Lawton and the original qualitative IADL scales. Results CDR 0.5/vmAD type subjects had impairment of only one Lawton item (Shopping) compared to CDR 0 subjects. However, the CDR 0.5/vmAD type group and the CDR 0.5/other type group showed impairment of 3 items in the qualitative assessment (Shopping, Food preparation, and Mode of transportation). Conclusion We suggest using both quantitative/qualitative IADL scales for assessing older adults with very mild dementia. PMID:27703470

    To date, studies have consistently demonstrated associations between either neuropsychological deficits or neuroanatomical changes and instrumental activities of daily living (IADL) in aging. Only a limited number of studies have evaluated morphological brain changes and neuropsychological test performance concurrently in relation to IADL in this population. As a result, it remains largely unknown whether these factors independently predict functional outcome. The current systematic review intended to address this lack of information by reviewing the literature on older adults, incorporating studies that examined e.g., normal aging, but also stroke or dementia patients. A comprehensive search of databases (Pubmed, Embase, Medline, Web of Science, PsycINFO) and reference lists was performed, focusing on papers in the English language that examined the combined effect of neuropsychological and neuroanatomical factors on IADL in samples of adults with an average age above 50. In total, 58 potential articles were identified; 20 were included in the review. The results show that especially neuropsychological variables (primarily memory and executive functions) independently predict IADL. Although some unique predictive value of brain morphological changes, such as hippocampal atrophy, was found, support for the importance of white matter changes was limited. However, the results of the studies reviewed are diverse, and appear to be at least partially determined by the variables included. For example, studies were less likely to find an independent effect of cognition if they solely employed a cognitive screening instrument. This indicates that a structured examination of neuroanatomical and neuropsychological correlates of IADL in different patient populations is warranted.

    [Purpose] This study aimed to investigate the effects of horse-riding exercise on balance, gait, and activities of daily living (ADLs) in stroke patients. [Subjects] Among 20 participants with stroke, 10 were randomly assigned to the experimental group, and 10 were randomly assigned to the control group. The experimental group participated in horse-riding exercise for 30 minutes per day, 5 days a week for 6 weeks. Balance was tested with the Berg Balance Scale (BBS). Gait was measured using the 10-Meter Walk Test (10MWT). ADLs were tested with the Modified Barthel Index (MBI). Differences between pre- and post-experiment values within the two groups were compared using paired t-tests. Between-group differences were compared using independent t-tests. [Results] The experimental group showed significant improvements in balance, gait, and ADLs following horse-riding exercise. Additionally, the experimental group showed significant differences in balance, gait, and ADLs compared with in the control group. [Conclusion] These results support that horse-riding exercise enhances balance, gait, and ADLs in stroke patients. This study supports the need for further research on horse-riding exercise programs.

    A purposive and convenience sample of 16 women and four men receiving informal and formal care for their activities of daily living either at home or institutions in Southeast Washington, USA was interviewed. Qualitative findings related to asking for help, getting and receiving help, interpersonal aspects of receiving help, and met and unmet needs are reported. Some seniors found it more difficult to ask for and accept help and there were gender differences, with men tending to adopt a more logical and pragmatic approach while women viewed receiving help as a loss of independence and an invasion of privacy. Intimacy and nudity were also threats for women. Three styles of adjustment and acceptance were identified within the data and related to positive acceptance, resigned acceptance and passive acceptance. There appeared to be a relationship between independence and control, with elders losing some independence but retaining control through choice, payment and involvement in decision making. Reciprocity was found to bring added value to relationships between care providers and elders, with a rhythm and symmetry developing in relationships where needs were known, anticipated and met. Seniors should be encouraged to plan for their future and to find out about local help and services available to them in advance of their requiring any assistance. PMID:11820550

    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.

[Subjects and Methods] Twenty-six participants comprised 2 groups. The experimental group (n=13) received combined fine motor skill and cognitive therapy, and the control group (n=13) received only general medical care. [Results] The experimental group showed improvements in cognition, degree of dementia, depression, and activities of daily living compared to the control group. However, there were no significant differences between the two groups. [Conclusion] These results suggest that combined fine motor skill and cognitive therapy improves cognition, degree of dementia, depression, and daily living in elderly patients with AD. These therapies would therefore be effective as general medical care strategies. PMID:26644663

    Objective The autonomy of individuals is linked to the achievement of instrumental activities of daily living that require complex behavior. In the elderly, the assessment of autonomy is usually based on questionnaires that have strong subjective constraints. Considering this fact, we tested elderly healthy adults and Alzheimer disease patients using a new measure, the S-IADL (Simulation of Instrumental Activities for Daily Living), to assess the ability to perform effectively activities of daily living. Method The S-IADL shares many items with the well-known IADL questionnaire proposed by Lawton & Brody (1969). However, as opposed to the IADL, the assessment of autonomy is not based on the completion of a questionnaire but requires the realization or simulation of various activities of daily living. Eighty-three participants (69 healthy elderly, and 14 Alzheimer Disease patients) completed the IADL and performed the S-IADL assessment. Results Results revealed that, like the IADL, the S-IADL is able to identify AD patients who are likely to encounter difficulties in performing everyday activities, and no major differences were found between the IADL and the S-IADL. Conclusions We outlined some advantages for prefering, in certain situation, this new tool based on simulation of activities in functional evaluation. Finally, we discuss the main limits of the S-IADL that should be investigated prior to its utilization by clinicians. PMID:27672491

    Background The dementia diagnosis gap in sub-Saharan Africa (SSA) is large, partly due to difficulties in assessing function, an essential step in diagnosis. Objectives As part of the Identification and Intervention for Dementia in Elderly Africans (IDEA) study, to develop, pilot, and validate an Instrumental Activities of Daily Living (IADL) questionnaire for use in a rural Tanzanian population to assist in the identification of people with dementia alongside cognitive screening. Design The questionnaire was developed at a workshop for rural primary healthcare workers, based on culturally appropriate roles and usual activities of elderly people in this community. It was piloted in 52 individuals under follow-up from a dementia prevalence study. Validation subsequently took place during a community dementia-screening programme. Construct validation against gold standard clinical dementia diagnosis using DSM-IV criteria was carried out on a stratified sample of the cohort and validity assessed using area under the receiver operating characteristic (AUROC) curve analysis. Results An 11-item questionnaire (IDEA-IADL) was developed after pilot testing. During formal validation on 130 community-dwelling elderly people who presented for screening, the AUROC curve was 0.896 for DSM-IV dementia when used in isolation and 0.937 when used in conjunction with the IDEA cognitive screen, previously validated in Tanzania. The internal consistency was 0.959. Performance on the IDEA-IADL was not biased with regard to age, gender or education level. Conclusions The IDEA-IADL questionnaire appears to be a useful aid to dementia screening in this setting. Further validation in other healthcare settings in SSA is required. PMID:25537940

[Subjects and Methods] Thirty subjects were assigned equally to a tDCS plus traditional occupational therapy group (experimental group) and a traditional occupational therapy group (control group). The intervention was implemented five times per week, 30 minutes each, for six weeks. In order to assess visual perception function before and after the intervention, the motor-free visual perception test (MVPT) was conducted, and in order to compare the performance of activities of daily living, the Functional Independence Measure scale was employed. [Results] According to the results, both groups improved in visual perception function and in performance of activities of daily living. Although there was no significant difference between the two groups, the experimental group exhibited higher scores. [Conclusion] In conclusion, the application of tDCS for the rehabilitation of patients with stroke may positively affect their visual perception and ability to perform activities of daily living.

    Little is known about the extent to which advanced activities of daily living among patients with dementia are preserved and how family caregivers of these patients support them in the community. In this cross-sectional assessment of pairs of patients with dementia and their family caregivers, we evaluated basic, instrumental, and advanced activities of daily living by comparing past and present status observed by caregivers with subjective estimations by patients with dementia. We also asked about ways in which support was provided by family caregivers. Thirty-nine pairs of patients with dementia and caregivers who presented to our memory clinic were interviewed. The mean age of patients with dementia was 75.3 ± 7.0 years, and Mini-Mental State Examination scores were 22.3 ± 3.4. We found relative preservation of advanced activities of daily living compared with instrumental activities of daily living. Caregivers provided instrumental, informational, and reminding support to patients with dementia. These findings may reinforce the concept of person-centered support of patients with dementia in the community. PMID:22811947

[Results] The values for balance, activities of daily living, and depressive disorder status significantly differed between before and after treatment in the experimental group, and significantly differed between the experimental group and control group. [Conclusion] Virtual reality dance exercise has a positive effect on balance, activities of daily living, and depressive disorder status of Parkinson’s disease patients. PMID:25642060

    [Purpose] The purpose of this study was to investigate the effects of training using video games played on the Xbox Kinect on the muscle strength, muscle tone, and activities of daily living of post-stroke patients. [Subjects] Fourteen stroke patients were recruited. They were randomly allocated into two groups; the experimental group (n=7) and the control group (n=7). [Methods] The experimental group performed training using video games played on the Xbox Kinect together with conventional occupational therapy for 6 weeks (1 hour/day, 3 days/week), and the control group received conventional occupational therapy only for 6 weeks (30 min/day, 3 days/week). Before and after the intervention, the participants were measured for muscle strength, muscle tone, and performance of activities of daily living. [Results] There were significant differences pre- and post-test in muscle strength of the upper extremities, except the wrist, and performance of activities of daily living in the experimental group. There were no significant differences between the two groups at post-test. [Conclusion] The training using video games played on the Xbox Kinect had a positive effect on the motor function and performance of activities of daily living. This study showed that training using video games played on the Xbox Kinect may be an effective intervention for the rehabilitation of stroke patients.

    Introduction 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. Methods 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. Results 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. Conclusions 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.

    We sought to assess the association of breast cancer-related lymphedema (BCRL) with the ability to perform upper extremity activities of daily living (ADL) in our patient population. 324 breast cancer patients who had received treatment for unilateral breast cancer at our institution between 2005 and 2014 were prospectively screened for lymphedema. Bilateral arm measurements were performed pre-operatively and during post-operative follow-up using a Perometer. Patients completed an extensive quality of life (QOL) questionnaire at the time of each study assessment. Lymphedema was defined as a relative volume change (RVC) of ≥10% from the patient's pre-operative baseline measurement. Linear regression models were used to evaluate the relationship between post-operative arm function score (as a continuous variable) and RVC, demographic, clinical, and QOL factors. By multivariate analysis, greater fear of lymphedema (p < 0.0001), more pain (p < 0.0001), body mass index >25 (p = 0.0015), mastectomy (p = 0.0001), and having an axillary node dissection (p = 0.0045) were all associated with lower functional scores. Higher emotional well-being score (p < 0.0001) and adjuvant chemotherapy (p = 0.0005) were associated with higher post-operative functional score. Neither low-level volume changes (5-10 % RVC) nor BCRL (RVC ≥10 %) were associated with ability to perform upper extremity ADL as measured by self-report (p = 0.99, p = 0.79). This prospective study demonstrates that low-level changes in arm volume (RVC 5-10 %) as well as clinically significant BCRL (RVC ≥10 %) did not impact the self-reported ability to use the affected extremity for ADL. These findings may help to inform clinicians and patients on the importance of prospective screening for lymphedema and QOL which enables early detection and intervention. PMID:25749734

    Aging and HIV are both risk factors for memory deficits and declines in real-world functioning. However, we know little about the profile of memory deficits driving instrumental activities of daily living (IADL) declines across the lifespan in HIV. This study examined 145 younger (<50 years) and 119 older (≥50 years) adults with HIV who completed the California Verbal Learning Test-Second Edition (CVLT-II), the Wechsler Memory Scale-Third Edition Logical Memory subtest (WMS-III LM), and a modified Lawton and Brody ADL questionnaire. No memory predictors of IADL dependence emerged in the younger cohort. In the older group, IADL dependence was uniquely associated with worse performance on all primary CVLT-II variables, as well as elevated recency effects. Poorer immediate and delayed recall of the WMS-III LM was also associated with IADL dependence, although recognition was intact. Findings suggest older HIV-infected adults with shallow encoding and forgetting are at risk for IADL dependence. PMID:24695591

    The aim of the current study was to examine the effectiveness of a school-centered multicomponent PA intervention, called 'Active Living', on children's daily PA levels. A quasi-experimental design was used including 9 intervention schools and 9 matched control schools located in the Netherlands. The baseline measurement took place between March-June 2013, and follow-up measurements were conducted 12months afterwards. Accelerometer (ActiGraph, GT3X+) data of 520 children aged 8-11years were collected and supplemented with demographics and weather conditions data. Implementation magnitude of the interventions was measured by keeping logbooks on the number of implemented physical environmental interventions (PEIs) and social environmental interventions (SEIs). Multilevel multivariate linear regression analyses were used to study changes in sedentary behavior (SB), light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) between baseline and follow-up. Finally, effect sizes (ESs) were calculated using Cohen's d. No pooled effects on PA and SB were found between children exposed and not exposed to Active Living after 12months. However, children attending Active Living schools that implemented larger numbers of both PEIs and SEIs engaged in 15 more minutes of LPA per weekday at follow-up than children in the control condition (ES=0.41; p<.05). Moreover, children attending these schools spent less time in SB at follow-up (ES=0.33), although this effect was non-significant. No significant effects were found on MVPA. A school-centered multicomponent PA intervention holds the potential to activate children, but a comprehensive set of intervention elements with a sufficient magnitude is necessary to achieve at least moderate effect sizes.

    Context: Activity of daily living (ADL) is an important predictor of mortality in patients with chronic obstructive pulmonary disease (COPD). Increasing ADL is important in patients with COPD and assessment of ADL is one of the best ways to evaluate the status of COPD patients. Objectives: The objective of this systematic review was to provide an overview of the psychometric properties of paper and pencil instruments measuring ADL in patients with COPD. Data Sources: English papers published from 1980 to 2014 regarding ADL in patients with COPD were searched in Web of Science, MEDLINE, Google Scholar, Cochrane, PubMed, ProQuest, and CINAHL databases using the following keywords: “COPD”, “ADL”, “activities of daily living”, “daily activities”, “instrument”, “questionnaire”, “paper-and-pencil instruments”, and “measure”. Following the Internet search, manual search was also done to find article references. Study Selection: A total of 186 articles were found. Of those, 31 met the inclusion criteria. Full texts of articles meeting the inclusion criteria were studied. Consensus-based standards for the selection of health measurement instruments”(COSMIN) were used to assess the quality of the studies. Data Extraction: Data extraction form based on research aims developed by researchers and psychometric experts, with 17 questions was used. Results: In these articles, 14 pen and paper instruments were identified for examining ADL in patients with COPD; of which, 4 dealt directly with ADL while 9 assessed other criteria i.e. dyspnea as ADL indicator. The majority of instruments only dealt with two main dimensions of ADL: Basic Activities of Daily Living (BADL) and Instrumental Activities of Daily Living (IADL), and did not consider Advanced Activities of Daily Living (AADL), which is influenced by cultural and motivational factors. Conclusion: Despite several ADL instruments identified, complete psychometric processes have only been done in

    The aims of this randomised controlled trial were to determine if a high-intensity functional exercise program improves balance, gait ability, and lower-limb strength in older persons dependent in activities of daily living and if an intake of protein-enriched energy supplement immediately after the exercises increases the effects of the training. One hundred and ninety-one older persons dependent in activities of daily living, living in residential care facilities, and with a Mini-Mental State Examination (MMSE) score of ? 10 participated. They were randomised to a high-intensity functional exercise program or a control activity, which included 29 sessions over 3 months, as well as to protein-enriched energy supplement or placebo. Berg Balance Scale, self-paced and maximum gait speed, and one-repetition maximum in lower-limb strength were followed-up at three and six months and analysed by 2 x 2 factorial ANCOVA, using the intention-to-treat principle. At three months, the exercise group had improved significantly in self-paced gait speed compared with the control group (mean difference 0.04 m/s, p = 0.02). At six months, there were significant improvements favouring the exercise group for Berg Balance Scale (1.9 points, p = 0.05), self-paced gait speed (0.05 m/s, p = 0.009), and lower-limb strength (10.8 kg, p = 0.03). No interaction effects were seen between the exercise and nutrition interventions. In conclusion, a high-intensity functional exercise program has positive long-term effects in balance, gait ability, and lower-limb strength for older persons dependent in activities of daily living. An intake of protein-enriched energy supplement immediately after the exercises does not appear to increase the effects of the training. PMID:16764547

    This paper focuses on the research on the state of the art for sensor fusion techniques, applied to the sensors embedded in mobile devices, as a means to help identify the mobile device user’s daily activities. Sensor data fusion techniques are used to consolidate the data collected from several sensors, increasing the reliability of the algorithms for the identification of the different activities. However, mobile devices have several constraints, e.g., low memory, low battery life and low processing power, and some data fusion techniques are not suited to this scenario. The main purpose of this paper is to present an overview of the state of the art to identify examples of sensor data fusion techniques that can be applied to the sensors available in mobile devices aiming to identify activities of daily living (ADLs).

    This study aimed to investigate whether knee pain during various activities of daily living (ADLs) is associated with physical activity in patients with early and severe knee osteoarthritis (OA). We hypothesized that the painful ADLs associated with decreased physical activity differ according to disease severity. This cross-sectional study enrolled 270 patients with medial knee OA, assigned to either the early (Kellgren Lawrence [K/L] grade 1-2) or the severe group (K/L grade 3-4). Physical activity was assessed using a pedometer. Knee pain during six ADLs (waking up in the morning, walking on a flat surface, ascending stairs, etc.) was evaluated using a questionnaire. We performed multiple regression and quantile regression analysis to investigate whether knee pain during each ADL was associated with physical activity. In the early group, the more knee pain they experienced while ascending stairs, the lower their physical activity was (75th regression coefficient = -1033.70, P = 0.018). In the severe group, the more knee pain they experienced while walking on a flat surface or bending to the floor or standing up, the lower their physical activity was (unstandardized coefficients = -1850.87, P = 0.026; unstandardized coefficients = -2640.35, P = 0.010). Knee pain while ascending stairs and while walking on a flat surface or bending to the floor or standing up was a probable limiting factor for physical activity in early and severe knee OA, respectively. These findings suggested that a reduction in task-specific knee pain according to disease severity could improve physical activity levels. PMID:27041381

    This study investigated the effects of leisure and social activities on the ability of middle-aged adults to maintain activities of daily living (ADL), and whether performing these activities alone or with others contributed to the ability to perform ADL. The study used nationally representative longitudinal data of 22,770 adults in Japan, aged 50–59 years, who did not have limitations in performing ADL at the beginning of the 5-year survey period. The study considered six activity categories: two leisure activities (“hobbies or cultural activities” and “exercise or sports”) and four social activities (“community events,” “support for children,” “support for elderly individuals,” and “other social activities”). Multiple logistic regression analysis was used to examine the relation between participation in these categories at baseline and difficulties in ADL at the 5-year follow-up. The association between the extent of social interaction during these activities (“by oneself,” “with others,” or “both”) and difficulties in ADL was also investigated. The analysis yielded significant negative correlations between “exercise or sports” and difficulties in ADL for both men and women, and between “hobbies or cultural activities” and difficulties in ADL for women. However, these significant relationships occurred only when activities were conducted “with others.” The present findings might help prevent deterioration in middle-aged adults’ performance of ADL in Japan.

  17. Designing and testing lightweight shoulder prostheses with hybrid actuators for movements involved in typical activities of daily living and impact absorption

    Unlike forearm amputees, transhumeral amputees have residual stumps that are too small to provide a sufficient range of operation for their prosthetic parts to perform usual activities of daily living. Furthermore, it is difficult for small residual stumps to provide sufficient impact absorption for safe manipulation in daily living, as intact arms do. Therefore, substitution of upper limb function in transhumeral amputees requires a sufficient range of motion and sufficient viscoelasticity for shoulder prostheses under critical weight and dimension constraints. We propose the use of two different types of actuators, ie, pneumatic elastic actuators (PEAs) and servo motors. PEAs offer high power-to-weight performance and have intrinsic viscoelasticity in comparison with motors or standard industrial pneumatic cylinder actuators. However, the usefulness of PEAs in large working spaces is limited because of their short strokes. Servo motors, in contrast, can be used to achieve large ranges of motion. In this study, the relationship between the force and stroke of PEAs was investigated. The impact absorption of both types of actuators was measured using a single degree-of-freedom prototype to evaluate actuator compliance for safety purposes. Based on the fundamental properties of the actuators identified, a four degree-of-freedom robotic arm is proposed for prosthetic use. The configuration of the actuators and functional parts was designed to achieve a specified range of motion and torque calculated from the results of a simulation of typical movements performed in usual activities of daily living. Our experimental results showed that the requirements for the shoulder prostheses could be satisfied. PMID:26185472

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

    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

[Subjects] This study included three stroke patients hospitalized in a sanatorium. [Methods] Intervention treatment involving prism glass use for 12 hours and 30 minutes and paretic side upper limb training was conducted 5 days a week for 15 weeks. Three upper limb training tasks (hitting a balloon, passing through a ring, and reading a newspaper) were performed for 10 minutes each session, for a total of 30 minutes. Line by Section, Motor-Free Visual Perception Test-3 (MVPT-3), Manual Function Test (MFT), Box & Block Test (BBT), and Assessment of Motor and Process Skills (AMPS) were conducted before and after intervention. [Results] Subjects' hemineglect decreased and upper limb function on the paretic side improved after intervention, which enhanced activities of daily living. [Conclusion] Prism glass use and paretic upper limb functional training effectively ameliorated stroke patients' hemineglect and improved upper limb function. Future research should focus on prism glasses that provide a wide visual field for use in patients with different conditions. PMID:26834386

    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

    Background There are currently only a few performance tests that assess the capacity to perform activities of daily living. These measures frequently require a long time to administer, are strongly cognition oriented, or have not been adequately validated. Methods The Erlangen Test of Activities of Daily Living in Mild Dementia (ETAM) was developed in a 4-phase process that was based on the International Classification of Functioning, Disability, and Health (ICF). A pilot study was conducted on 30 subjects with mild dementia with a mean age of 80 years. The subjects' mean score on the MMSE was 21.5. Twenty-one of the 30 subjects were women. Results Ten items were developed and tested in the pilot study. The mean time required to complete the test was 26 min. The item analysis showed difficulties that ranged primarily from r = 0.28 to r = 0.79. The ETAM had a moderate correlation with the MMSE (rMMSE = 0.310) and a low correlation with the Geriatric Depression Scale-15 (GDS-15; rGDS-15 = 0.149). Conclusion The preliminary version of the ETAM is quick and easy to use and has predominantly satisfactory item characteristics. There still is the need to revise the items ‘giving directions’ and ‘making tea’ with regard to standardisation. PMID:25873929

Future research should focus on prism glasses that provide a wide visual field for use in patients with different conditions. PMID:26834386

    The wear, delamination, and fatigue resistance of artificially aged gamma irradiation-sterilized conventional polyethylene (CPE) and gas-plasma-sterilized melt-annealed highly crosslinked polyethylene tibial inserts (HXPE) were compared. Six CPE and 12 HXPE (six irradiated at 58 kGy and six at 72 kGy) left knee inserts were wear tested for 5.5 million cycles (Mc) under loads and motions that mimic activities of daily living, such as walking, chair rise, stair ascent, and deep squatting. Another six HXPE (72 kGy) and six CPE inserts were also tested under conditions that could produce severe delamination for 8 Mc. Ten other knees (five 72 kGy HXPE and five CPE) were subjected to posterior edge loading fatigue testing for 5 Mc. The HXPE inserts had an average wear rate reduction of about 80% relative to their CPE counterparts during all activities. All of the CPE inserts delaminated and fractured during high cycle deep squat (152 degrees flexion) motions, while all the HXPE remained intact. None of the HXPE inserts delaminated after 8 Mc, while all of the CPE inserts developed delamination damage within 1.5-5.8 Mc of delamination testing. All CPE inserts developed subsurface cracks and delamination within 2.8 Mc during posterior edge loading fatigue studies, while none of the HXPE inserts showed cracking or delamination after 5 Mc. These results show that aged HXPE has higher wear and fatigue resistance than aged CPE, and offers potential long-term advantages for young active patients with sustained activities of daily living.

    The influence of physical activity on the maintenance and adaptation of musculoskeletal tissue is difficult to assess. Cumulative musculoskeletal loading is hard to quantify and the attributes of the daily tissue loading history affecting bone metabolism have not been completely identified. By monitoring the vertical component of the daily ground reaction force (GRFz), we have an indirect measure of cumulative daily lower limb musculoskeletal loading to correlate with bone density and structure. The objective of this research is to develop instrumentation and methods of analysis to quantify activity level in terms of the daily history of ground reaction forces.

    [Purpose] Primary care is considered the gateway to the Brazilian public health system and is responsible for managing the most prevalent problems in the population. In this study, the effects of Back School on pain, functionality, and the performance of activities of daily living (ADL) in users with chronic musculoskeletal pain were evaluated. [Subjects and Methods] Forty-four users (33 females and 11 males) participated in Back School, with five two-hour theoretical and practical meetings held once a week. The assessment instruments used were as follows: (a) a circuit evaluation of posture dynamics recorded on video, (b) an observational instrument of ADL using video, (c) anamnesis, (d) the visual analogue scale, and (e) the Oswestry Disability Index. [Results] The results showed decreased pain intensity, improved functionality, and the recovery of ADL. [Conclusion] The Back School program is an effective health education strategy for users with chronic musculoskeletal pain. PMID:27799699

    Rotator cuff tears (RCT) in older individuals may compound age-associated physiological changes and impact their ability to perform daily functional tasks. Our objective was to quantify thoracohumeral kinematics for functional tasks in 18 older adults (mean age=63.3±2.2), and compare findings from nine with a RCT to nine matched controls. Motion capture was used to record kinematics for 7 tasks (axilla wash, forward reach, functional pull, hair comb, perineal care, upward reach to 90°, upward reach to 105°) spanning the upper limb workspace. Maximum and minimum joint angles and motion excursion for the three thoracohumeral degrees of freedom (elevation plane, elevation, axial rotation) were identified for each task and compared between groups. The RCT group used greater minimum elevation angles for axilla wash and functional pull (p≤0.0124) and a smaller motion excursion for functional pull (p=0.0032) compared to the control group. The RCT group also used a more internally rotated maximum axial rotation angle than controls for functional reach, functional pull, hair comb, and upward reach to 105° (p≤0.0494). The most differences between groups were observed for axial rotation, with the RCT group using greater internal rotation to complete functional tasks, and significant differences between groups were identified for all three thoracohumeral degrees of freedom for functional pull. We conclude that older adults with RCT used more internal rotation to perform functional tasks than controls. The kinematic differences identified in this study may have consequences for progression of shoulder damage and further functional impairment in older adults with RCT. PMID:26879327

    We determined the interrelations of chronological age, age at seizure onset, duration of seizure disorder, cognitive functioning (IQ), scales of activities of daily living, depressive mood disorder and measures of health-related quality of life (HRQOL). Furthermore, we investigated the association of the laterality of seizure onset zone and absence/presence of hippocampal atrophy and/or sclerosis (HA/HS) with measures of HRQOL, activities of daily living (ADL) and depressive mood disorder. In the setting of pre-surgical epilepsy evaluation, a sample of 56 patients with temporal lobe epilepsy (TLE) was studied using the Bonner Skalen für Epilepsie (BPSE) and the depression inventory D-S of von Zerssen. Patients reported high levels of dependency on others and poor coping capabilities. Our data also showed specific ADL-behaviour suggesting social withdrawal and isolation. Our results indicate emotional impairment as a major problem in TLE, because 45% of our patients scored in the depressive range of the D-S depression scale. Depression score was found to be a powerful predictor of self-reported quality of life after adjusting for seizure-related variables, demographic variables and cognitive functioning (IQ). The only scale showing a significant laterality effect was ADL-home. No relationship between the dependent measures of HRQOL, ADL-social, ADL-cultural, depressive mood disorder and laterality of the epileptogenic zone or absence/presence of HA/HS was found. HRQOL and depressive mood disorder are strongly interrelated indicating that patients with depressive symptoms report lower quality of life and specific patterns of ADL. HRQOL, ADL and depressive mood disorder are largely independent of biological markers such as laterality of seizure onset zone and absence/presence of HA/HS in TLE.

    Background Patellofemoral pain syndrome (PFPS) is one of the most common disorders of the knee. Conservative approaches, as well as surgery, can decrease pain and the syndrome’s progress effectively. Objective The aim of this study was to determine the effectiveness of neoprene palumbo orthosis (NPO) and Genu direxa stable orthosis (GDSO) on pain and the activities of daily living (ADL). Methods Thirty patients (males, ages 18 to 40) participated in this randomized blinded clinical trial. All of them were diagnosed with patella femoral pain syndrome. The participants were divided randomly into two groups of 15, with one group using neoprene palumbo (intervention group) and the other group using Genu direxa stable orthoses (control group). Using the Visual Analogue Scale (VAS) and the Knee injury and Osteoarthritis Outcome Score (KOOS), pain intensity and activities of daily living (ADL) and joint stiffness were analyzed before treatment and after three weeks of treatment. Data were analyzed using paired samples t-test and independent samples t-test. Results Both orthoses reduced the patients’ pain. Both group showed meaningful improvement in pain reduction and ADL increase after using orthosis in each group. In comparing the variables, no significant differences were found between pain severity and ADL (p = 0.592, p = 0.887). In both groups, the mean of pain severity was different before, during, and after using orthosis (p < 0.05). Conclusion The results of this study indicated that Neoprene palumbo and genudirexa stable orthoses improved the signs of patello femoral pain syndrome, including pain intensity and ADL.

    Abstract This study assesses the validity, reliability, and responsiveness of the Dutch version of the London Chest Activity of Daily Living scale (LCADL). The English LCADL version was translated into Dutch and then back-translated to English to check if the translation was conceptually equivalent to the original LCADL. Measurement properties were evaluated in191 patients with chronic obstructive pulmonary disease (COPD) (70 males; age 62 ± 9 years; FEV1 33 ± 10% pred). Construct validity was assessed using disease-specific health status, generic functional status, and functional and peak exercise capacity (Wmax). LCADL was completed twice to assess test–retest reliability. Responsiveness was assessed after 8 to 12 weeks inpatient pulmonary rehabilitation. LCADL correlated significantly with the St. George Respiratory Questionnaire (r = 0.24 to 0.64), functional status (r = 0.45 to 0.82), walking distance (r = −0.3 to −0.58), and Wmax (−0.27 to −0.38) and Wmax % pred (−0.26 to −0.43). Test–retest reliability was high (ICC 0.87 to 0.98). The smallest detectable change for the LCADL total and domain score self-care, domestic, physical, and leisure was 4.5, 2.9, 3.3, 4.9, and 2.2, respectively. Improvement in LCADL after PR correlated significantly with improvement in Chronic Respiratory Questionnaire (−0.43; P < 0.001). The Dutch LCADL is a reliable, valid, and responsive instrument to assess limitations in performing activities of daily living in patients with severe COPD. PMID:26656349

    Background The Dutch Walking Stairs, Walking Ability and Rising and Sitting Questionnaires are three validated instruments to measure physical activity and limitations in daily living in patients with lower extremity disorders living at home of which no German equivalents are available. Our scope was to translate the Walking Stairs, Walking Ability and Rising and Sitting Questionnaires into German and to verify its concurrent validity in the two domains pain and activities in daily living by comparing them with the corresponding measures on the Visual Analogue Scale. Methods We translated the Walking Stairs, Walking Ability and Rising and Sitting Questionnaires according to published guidelines. Demographic data and validity were assessed in 52 consecutive patients with Complex Regional Pain Syndrome 1 of the lower extremity. Information on age, duration of symptoms, type of Complex Regional Pain Syndrome 1 and type of initiating event were obtained. We assessed the concurrent validity in the two domains pain and activities in daily living by comparing them with the corresponding measures on the Visual Analogue Scale. Results We found that variability in the German Walking Stairs, Walking Ability and Rising and Sitting Questionnaires was largely explained by measures of pain and activities in daily living on the Visual Analogue Scale. Conclusion Our study shows that the domains pain and activities in daily living are properly represented in the German versions of the Walking Stairs, Walking Ability and Raising and Sitting Questionnaires. We would like to propagate their use in clinical practice and research alike. PMID:20515456

    Elderly individuals undergo a progressive decline in functional capacity related to increased risk of dependency, loss of autonomy, and frailty. A lower cardiorespiratory fitness level is associated with cardiovascular disease events and mortality from all causes. The Veterans Specific Activity Questionnaire (VSAQ) was developed to facilitate prediction of the exercise capacity in older people with cardiovascular disease. However, few studies have investigated the relationship between the VSAQ and functional capacity in elderly women. This study investigated the relationship between functional capacity and the estimated cardiovascular capacity in elderly women, as assessed by the VSAQ. In this descriptive, observational, cross-sectional study, we evaluated 37 healthy elderly women (aged 70 ± 7 years). The assessment protocols used were the following: Anamnesis, VSAQ and nomogram (age adjusted), Senior Fitness Test (30-s chair stand, to assess lower-body strength; 8-foot up-and-go test, to assess agility-dynamic balance; and 2-min step test, to assess aerobic endurance). The Spearman test showed a significant correlation (p<0.001) between the functional tests and the VSAQ (8-foot up-and-go test rs=-0.715; 2-min step test rs=0.567; 30-s chair stand rs=0.582). Adjustment of the results by age improved the correlation (8-foot up-and-go test rs=-0.760; 2-min step test rs=0.627; 30-s chair stand rs=0.601). The VSAQ seems to be a simple way to estimate functional capacity, particularly in older women. PMID:24948514

    Mobus is a cognitive orthotic designed for people with difficulties managing Activities of Daily Living (ADL), as encountered in schizophrenia. It provides a schedule manager as well as the possibility to report occurrences of symptomatic experiences. Receiving this information by Internet, caregivers can assist the patient rehabilitation process. Our aim was to explore the use and satisfaction of Mobus by people with schizophrenia. Nine outpatients tested Mobus for 6 weeks. Indicators of cognitive functioning and autonomy were measured with the CAmbridge Neuropsychological Tests Automated Battery (CANTAB) and the Independant Living Skills Scale (ILSS). On average, 42.6% of the planned ADL were validated and more than 1 symptom per week were reported. Mainly because of technical breakdown, more than 50% of the outpatients evaluated the Mobus satisfaction below 1.7/5, nevertheless 3 participants appreciated it greatly. Some enhancements were found on subscales of CANTAB and ILSS and some participants reported that they acquired planning skills by using Mobus. To ensure ease of use, refinements are needed from rehabilitation and technical approaches, especially to personalize the device. Discussions on ethical and methodological issues lead to an improved version of Mobus that will be tested with a larger sample size. PMID:22876729

    A recent trend in human motion capture is the use of inertial measurement units (IMUs) for monitoring and performance evaluation of mobility in the natural living environment. Although the use of such systems have grown significantly, the development of methods and algorithms to process IMU data for clinical purposes is still limited. The aim of this work is to develop algorithms based on wavelet transform and discrete-time detection of events for the automatic segmentation of tasks related activities of daily living (ADL) from body worn IMUs. Seven healthy older adults (73  ±  4 years old) performed 10 ADL tasks in a simulated apartment during trials of different durations (3, 4, and 5 min). They wore a suit (Synertial UK Ltd IGS-180) comprised of 17 IMUs positioned strategically on body segments to capture full body motion. The proposed method automatically detected the number of template waveforms (representing each movement separately) using discrete wavelet transform (DWT) and discrete-time detection of events based on angular velocity, linear acceleration and 3D orientation data of pertinent IMUs. The sensitivity (Se.) and specificity (Sp.) of detection for the proposed method was established using time stamps of10tasks obtained from visual segmentation of each trial using the video records and the avatar provided by the system's software. At first, we identified six pertinent sensors that were strongly associated to different activities (at most two sensors/task) that allowed detection of tasks with high accuracy. The proposed algorithm exhibited significant global accuracy (N events  =  1999, Se.  =  97.5%, Sp.  =  94%), despite the variation in the occurrences of the performed tasks (free living). The Se. varied from 94% to 100% for all the detected ADL tasks and Sp. ranged from 90% to 100% with the worst Sp.  =  85 and 87% for Release_mid (reaching for object held just beyond reach at chest height) and Turning

    A problem that is common to the study of upper limb kinematics and gait analysis is the translation of the evidence from kinematic measurements into easily interpretable information on the status of the patient, such as the amount of compensation or lack of motion. In this study parameters that can be helpful in the rapid and clear identification of limited wrist motion and compensation were derived from kinematic data. A group of six subjects (group A) with no hand impairment, average age 32.5 ys SD 10.7 ys, and another group of five subjects (group B), average age 34.2 ys SD 16.8 ys, having suffered from distal radius fracture were tested during a cyclic activity of daily living. The activity simulated page turning. Thorax, shoulder, elbow and wrist angles were measured during this task using a motion capture system. Corresponding angle ranges were also calculated. The active range of motion (AROM) found for Group B was generally lower than that of Group A, particularly for elbow supination and wrist movements, with wrist flexion/extension statistically smaller for group B (P=0.02). Additional parameters that took into account lack of movements at the wrist and compensation from shoulder elevation, rotation and elbow pronation/supination proved to be more useful at identifying those subjects of group B outside the normative range and can provide clinicians with a rapid and efficient tool that can shorten the analysis process and help make more informed decisions on therapeutic treatments.

    BACKGROUND: In a cross-sectional study examining late effects of pediatric sarcoma therapy, long-term survivors were evaluated on their activities of daily living (ADL) performance. PROCEDURE: Thirty-two persons with Ewing sarcoma family of tumors, rhabdomyosarcoma, and non-rhabdomysarcoma-soft tissue sarcoma enrolled an average of 17 years after treatment. Participants were evaluated using the Assessment of Motor and Process Skills (AMPS) [1], a standardized observational evaluation of ADL task performance. Means and 95% confidence intervals for ADL motor and ADL process ability measures were calculated for four groups: 1) sarcoma survivors, 2) “well” adults matched for age and gender, 3) “well” adults matched for gender that were 10 years older; and 4) “well” adults matched for gender that were 20 years older. RESULTS: ADL motor ability was significantly lower for sarcoma survivors than for the age and gender matched comparison group (p<0.05). There was no significant difference between ADL motor ability of sarcoma survivors and the comparison group 10 years older, but sarcoma survivors had significantly better ADL motor ability (p<0.05) than the oldest comparison group (20 years older). Sarcoma survivors had significantly worse ADL process ability than the age matched group (p<0.05). There was no difference in ADL process ability between the sarcoma survivors and comparison groups that were 10 and 20 years older. CONCLUSIONS: This first report of a clinical evaluation of ADL limitation in pediatric sarcoma survivors treated with intensive multimodal cancer therapy suggests that influences on performance of daily life activities are more common than previously reported.

    ABSTRACT Background The Glittre-ADL test (TGlittre) is a valid and reliable test for the evaluation of functional capacity and involves multiple physical activities of daily living (PADL), which are known to be troublesome to patients with Chronic Obstructive Pulmonary Disease (COPD). However, it is still unknown if this test is also able to reflect the functional performance of patients with COPD. Objective To investigate whether the TGlittre reflects the functional performance of COPD patients and whether the necessary time to complete the TGlittre and the PADL varies according to disease severity. Method Thirty-eight patients with COPD (age 65, SD=7 years; forced expiratory volume in the first second 41.3, SD=15.2% predicted) underwent anthropometric and lung function assessments and were submitted to the TGlittre and PADL measurement. Results TGlittre performance correlated significantly (p<0.05) with PADL variables, such as time sitting (r=0.50), walking (r=-0.46), number of steps taken (r=–0.53), walking movement intensity (r=–0.66), walking energy expenditure (r=-0.50), and total energy expenditure (r=–0.33). TGlittre performance was not significantly different in patients among the Global Initiative for COPD (GOLD) spirometric stages, but walking and sitting time were significantly lower and greater, respectively, in severe and very severe patients compared to those with moderate disease (p<0.05). Conclusion The performance on the TGlittre correlates with walking and sitting time and other real life PADL measurements. The severity of the disease is associated with the differences in the level of physical activity in daily life more than in functional capacity. PMID:27437713

    The well-publicized aging of Western societies has prompted a growing interest into technologies that support awareness in cross-generational families. The idea of supporting continual and partly automated flow of information between seniors living alone and their social intimates has been gaining ground among researchers but even among industries. It is anticipated that such an information flow can help bridge geographical distance, discrepant lifestyles, and daily routines, potentially providing peace of mind to both parties and feelings of being connected.

    Objective : To translate The Manchester Respiratory Activities of Daily Living (MRADL) questionnaire into Portuguese and to create a version of the MRADL that is cross-culturally adapted for use in Brazil. Methods : The English-language version of the MRADL was translated into Portuguese by two health care researchers who were fluent in English. A consensus version was obtained by other two researchers and a pulmonologist. That version was back-translated into English by another translator who was a native speaker of English and fluent in Portuguese. The cognitive debriefing process consisted in having 10 COPD patients complete the translated questionnaire in order to test its understandability, clarity, and acceptability in the target population. On the basis of the results, the final Portuguese-language version of the MRADL was produced and approved by the committee and one of the authors of the original questionnaire. Results : The author of the MRADL questioned only a few items in the translated version, and some changes were made to the mobility and personal hygiene domains. Cultural differences regarding the domestic activities domain were found, in particular regarding the item "Do you have the ability to do a full clothes wash and hang them out to dry?", due to socioeconomic and climatic issues. The item "Do you take care of your garden?" was questioned by the participants who lived in apartments, being modified to "Do you take care of your garden or plants in your apartment?" Conclusions : The final Portuguese-language version of the MRADL adapted for use in Brazil was found to be easy to understand and easily applied. PMID:26982036

    There is increasing interest in wearable sensor technology as a tool for rehabilitation applications in community or home environments. Recent studies have focused on evaluating inertial based sensing (accelerometers, gyroscopes, etc.) that provide only indirect measures of joint motion. Measurement of joint kinematics using flexible goniometry is more direct, and still popular in laboratory environments, but has received little attention as a potential tool for wearable systems. The aim of this study was to compare two goniometric devices: a traditional strain-gauge flexible goniometer, and a fiberoptic flexible goniometer, for measuring dynamic knee flexion/extension angles during activity of daily living: chair rise, and gait; and exercise: deep knee bends, against joint angles computed from a "gold standard" Vicon motion tracking system. Six young adults were recruited to perform the above activities in the lab while wearing a goniometer on each knee, and reflective markers for motion tracking. Kinematic data were collected simultaneously from the goniometers (one on each leg) and the motion tracking system (both legs). The results indicate that both goniometers were within 2-5 degrees of the Vicon angles for gait and chair rise. For some deep knee bend trials, disagreement with Vicon angles exceeded ten degrees for both devices. We conclude that both goniometers can record ADL knee movement faithfully and accurately, but should be carefully considered when high (>120 deg) knee flexion angles are required.

    [Purpose] This study was conducted to compare the correlation between social interaction and activities of daily living (ADL) between community-dwelling and long-term care facility stroke patients. [Subjects and Methods] The Subjects were 65 chronic stroke patients (32 facility-residing, 33 community-dwelling). The Evaluation Social Interaction (ESI) tool was used to evaluate social interaction and the Assessment of Motor and Process Skills (AMPS) measure was used to evaluate ADL. [Results] Both social interaction and ADL were higher in community-dwelling than facility-residing stroke patients. There was a correlation between ESI and ADL for both motor and process skills among facility-residing patients, while only ADL process skills and ESI correlated among community-dwelling patients. In a partial correlation analysis using ADL motor and process skills as control variables, only process skills correlated with ESI. [Conclusion] For rehabilitation of stroke patients, an extended treatment process that combines ADL and social activities is likely to be required. Furthermore, treatment programs and institutional systems that can improve social interaction and promote health maintenance for community-dwelling and facility-residing chronic stroke patients are needed throughout the rehabilitation process.

    There is increasing interest in wearable sensor technology as a tool for rehabilitation applications in community or home environments. Recent studies have focused on evaluating inertial based sensing (accelerometers, gyroscopes, etc.) that provide only indirect measures of joint motion. Measurement of joint kinematics using flexible goniometry is more direct, and still popular in laboratory environments, but has received little attention as a potential tool for wearable systems. The aim of this study was to compare two goniometric devices: a traditional strain-gauge flexible goniometer, and a fiberoptic flexible goniometer, for measuring dynamic knee flexion/extension angles during activity of daily living: chair rise, and gait; and exercise: deep knee bends, against joint angles computed from a "gold standard" Vicon motion tracking system. Six young adults were recruited to perform the above activities in the lab while wearing a goniometer on each knee, and reflective markers for motion tracking. Kinematic data were collected simultaneously from the goniometers (one on each leg) and the motion tracking system (both legs). The results indicate that both goniometers were within 2-5 degrees of the Vicon angles for gait and chair rise. For some deep knee bend trials, disagreement with Vicon angles exceeded ten degrees for both devices. We conclude that both goniometers can record ADL knee movement faithfully and accurately, but should be carefully considered when high (>120 deg) knee flexion angles are required. PMID:22938362

    Multi-sensory stimulation provided in a Snoezelen room is being used increasingly for individuals with mental retardation and mental illness to facilitate relaxation, provide enjoyment, and inhibit behavioral challenges. We observed aggressive and self-injurious behavior in three groups of 15 individuals with severe or profound mental retardation and mental illness before, during, and after being in a Snoezelen room. All participants were receiving psychotropic medication for their mental illness and function-derived behavioral interventions for aggression, self-injury, or both. Using a repeated measures counterbalanced design, each group of participants was rotated through three experimental conditions: Activities of Daily Living (ADL) skills training, Snoezelen, and Vocational skills training. All other treatment and training activities specified in each individual's person-centered plan were continued during the 10-week observational period. Both aggression and self-injury were lowest when the individuals were in a Snoezelen room, followed by Vocational skills training and ADL skills training. The levels in the Snoezelen room were significantly lower than in both the other conditions for aggression but only in ADL skills training for self-injury. The difference in levels before and after Snoezelen were statistically significant with self-injury but not with aggression. The order of conditions showed no significant effect on either behavior. Snoezelen may provide an effective context for reducing the occurrence of self-injury and aggression.

    Currently, the assessment of autonomy and functional ability involves clinical rating scales. However, scales are often limited in their ability to provide objective and sensitive information. By contrast, information and communication technologies may overcome these limitations by capturing more fully functional as well as cognitive disturbances associated with Alzheimer disease (AD). We investigated the quantitative assessment of autonomy in dementia patients based not only on gait analysis but also on the participant performance on instrumental activities of daily living (IADL) automatically recognized by a video event monitoring system (EMS). Three groups of participants (healthy controls, mild cognitive impairment, and AD patients) had to carry out a standardized scenario consisting of physical tasks (single and dual task) and several IADL such as preparing a pillbox or making a phone call while being recorded. After, video sensor data were processed by an EMS that automatically extracts kinematic parameters of the participants' gait and recognizes their carried out activities. These parameters were then used for the assessment of the participants' performance levels, here referred as autonomy. Autonomy assessment was approached as classification task using artificial intelligence methods that takes as input the parameters extracted by the EMS, here referred as behavioral profile. Activities were accurately recognized by the EMS with high precision. The most accurately recognized activities were "prepare medication" with 93% and "using phone" with 89% precision. The diagnostic group classifier obtained a precision of 73.46% when combining the analyses of physical tasks with IADL. In a further analysis, the created autonomy group classifier which obtained a precision of 83.67% when combining physical tasks and IADL.

    The system watching over elder's life is very important in a super-aged society Japan. In this paper, we describe a method to recognize resident's daily activities by means of using the information of indoor ambient atmosphere changes. The measuring targets of environmental changes are of gas and smell, temperature, humidity, and brightness. Those changes have much relation with resident's daily activities. The measurement system with 7 sensors (4 gas sensors, a thermistor, humidity sensor, and CdS light sensor) was developed for getting indoor ambient atmosphere changes. Some measurements were done in a one-room type residential space. 21 dimensional activity vectors were composed for each daily activity from acquired data. Those vectors were classified into 9 categories that were main activities by using Self-Organizing Map (SOM) method. From the result, it was found that the recognition of main daily activities based on information on indoor ambient atmosphere changes is possible. Moreover, we also describe the method for getting information of local gas and smell environmental changes. Gas and smell environmental changes are related with daily activities, especially very important action, eating and drinking. And, local information enables the relation of the place and the activity. For such a purpose, a gas sensing module with the operation function that synchronizes with human detection signal was developed and evaluated. From the result, the sensor module had the ability to acquire and to emphasize local gas environment changes caused by the person's activity.

    Smart homes for the aging population have recently started attracting the attention of the research community. The "health state" of smart homes is comprised of many different levels; starting with the physical health of citizens, it also includes longer-term health norms and outcomes, as well as the arena of positive behavior changes. One of the problems of interest is to monitor the activities of daily living (ADL) of the elderly, aiming at their protection and well-being. For this purpose, we installed passive infrared (PIR) sensors to detect motion in a specific area inside a smart apartment and used them to collect a set of ADL. In a novel approach, we describe a technology that allows the ground truth collected in one smart home to train activity recognition systems for other smart homes. We asked the users to label all instances of all ADL only once and subsequently applied data mining techniques to cluster in-home sensor firings. Each cluster would therefore represent the instances of the same activity. Once the clusters were associated to their corresponding activities, our system was able to recognize future activities. To improve the activity recognition accuracy, our system preprocessed raw sensor data by identifying overlapping activities. To evaluate the recognition performance from a 200-day dataset, we implemented three different active learning classification algorithms and compared their performance: naive Bayesian (NB), support vector machine (SVM) and random forest (RF). Based on our results, the RF classifier recognized activities with an average specificity of 96.53%, a sensitivity of 68.49%, a precision of 74.41% and an F-measure of 71.33%, outperforming both the NB and SVM classifiers. Further clustering markedly improved the results of the RF classifier. An activity recognition system based on PIR sensors in conjunction with a clustering classification approach was able to detect ADL from datasets collected from different homes. Thus, our

    The prevalence of non-motor symptoms (NMS) in Parkinson's Disease (PD) has varied between studies. Their interrelation isn't totally understood. Also, the relative importance of each symptom, regarding its impact on activities of daily living (ADL) and health related quality of life (HRQL), remains debatable. We assessed all PD patients attending a Portuguese tertiary movement disorders center during one year (n = 134), with ADL, HRQL and other clinical scales approved for identifying the most relevant NMS in PD. All patients had at least one NMS. Sleep/fatigue, affect/cognition, attention/memory were the most frequent complaints, and their prevalence, above 80%, was higher than in most studies. There were significantly correlations between: sleepiness, psychosis and cognition; gastrointestinal, cardiovascular symptoms and pain; depression and apathy; anxiety and insomnia; olfaction, weight and hyperhidrosis. Depression/apathy exerted the strongest influence on HRQL and non-tremor motor dysfunction on ADL. Compared to studies in other countries, we found a higher prevalence of NMS, which could be specific of this population. The interrelation between NMS could be related to degeneration of different brain structures. NMS exert a stronger influence than MS in HRQL, which should be taken in account regarding treatment options. PMID:27573215

    Background. Gait speed is as an important predictor of mortality, volume of medical care, hospitalization, onset of activities of daily living (ADL) disability, and nursing home placement. We examined associations between change in gait speed and change in observed performance in the instrumental ADL (IADL) in a sample of mild-to-moderately disabled older adults. Methods. Participants in the Sources of Independence in the Elderly project (n = 375) were approached to complete a 4-m gait assessment and a performance test of IADL competency at three points over 2 years. IADL competency was assessed by occupational therapists, who rated participants using the Assessment of Motor and Process Skills (AMPS) and who also made a global rating of need for help or supervision. Linear mixed models were developed to assess change in motor AMPS score relative to baseline status and change in gait speed and AMPS process scores. Results. Baseline gait and change in gait were significant correlates of change in the AMPS motor ability measures in models that adjusted for cognitive status and AMPS process ability. Even respondents with gait speeds of 1 m/s at baseline were at risk of declining AMPS motor ability and an occupational therapist rating of IADL disability if gait speed declined. Conclusions. Slowing in gait speed is an important risk factor for IADL disability in mild to moderately disabled older adults. PMID:24952575

    Background. Instrumental activities of daily living (IADLs) exhibit strong predictive power for the presence of dementia and mild cognitive impairment. However, IADLs are often less effective in younger cohorts or in healthy community-dwelling samples, presenting with large ceiling effects. This study aimed to construct an IADL scale with an extended range. An effort was made to incorporate leisure activity tasks that were more stimulating, and potentially more challenging, into a set of traditional IADLs. Methods. Beginning with a set of IADL and leisure activity items, nonparametric item response theory methodology was used to construct a scale with appropriate dimensionality, monotonicity, item discrimination power, and scalability within a large cohort of young–old (aged 65–75). Dimensionality was further scrutinized by principal component analysis of the residuals. The predictive validity of the resulting scale for poor cognitive performance was evaluated using logistic regression. Results. A reliable (ρ = .73) unidimensional construct was established, meeting the Mokken item response theory criteria of medium scalability. Excluding demented participants, the adjusted model proved sensitive to relatively subtle cognitive deficits; each additional task endorsed (nine-item scale) significantly decreased the odds of being in the bottom quarter of composite domains relating to processing speed (odds ratio = 0.73 [confidence interval: 0.56–0.97], p < .05) and visuospatial ability (odds ratio = 0.70 [confidence interval: 0.73–0.87], p < .01). Conclusions. A reliable extended-IADL scale was constructed meeting item response theory assumptions relating to unidimensionality, monotonicity, and invariant item ordering. The range of measurement extends well beyond traditional IADL scales. Finally, the scale appears to be sensitive to cognitive differences within the normal spectrum. PMID:24149431

    Spatial neglect is most frequently observed after right-hemispheric stroke and is characterized by a failure to report, to respond, or to orient to stimuli presented to the contralesional side. Although many neglect patients show difficulties in accomplishing activities of daily living (ADL), to date the clinical assessment of neglect is based upon neuropsychological paper-and-pencil tests. Thus, essential information about the patient's functional status may be missed out. Accordingly, we aimed at developing a new neglect test battery that incorporates standardized ADL. Six conventional paper-and-pencil neglect tests and eight standardized ADL with newly developed neglect-specific scoring criteria and cut-off scores were administered to 68 right-hemispheric stroke patients. According to the neuropsychological tests 22 patients showed symptoms suggesting neglect, whereas 17 patients showed symptoms suggesting neglect according to the newly developed neglect test based upon ADL. Neglect-specific impairments in the neuropsychological tests were significantly associated with those in the ADL-based tests, although dissociations were observed in seven patients. Neglect severity (as reflected in the percentage of positive subtests) was comparable for both test batteries and both test instruments showed high interrater reliability. Voxel-based lesion-symptom mapping revealed that the severity of neglect according to the neuropsychological and ADL-based tests was significantly associated with lesions within right fronto-parietal networks. We conclude that the newly developed ADL-based neglect battery provides an economic and ecologically valid tool for the assessment of neglect. The test can be used to assess and quantify neglect in everyday activities, and thus to monitor realistically rehabilitative needs of neglect patients.

    Background: The assessment of activities of daily living (ADL) is essential for dementia diagnostics. Even in mild cognitive impairment (MCI), subtle deficits in instrumental ADL (IADL) may occur and signal a higher risk of conversion to dementia. Thus, sensitive and reliable ADL assessment tools are important. Smart homes equipped with sensor technology and video cameras may provide a proxy-free assessment tool for the detection of IADL deficits. Objective:The aim of this paper is to investigate the potential of a smart home environment for the assessment of IADL in MCI. Method: The smart home consisted of a two-room flat equipped with activity sensors and video cameras. Participants with either MCI or healthy controls (HC) had to solve a standardized set of six tasks, e.g., meal preparation, telephone use, and finding objects in the flat. Results: MCI participants needed more time (1384 versus 938 seconds, p <  0.001) and scored less total points (48 versus 57 points, p <  0.001) while solving the tasks than HC. Analyzing the subtasks, intergroup differences were observed for making a phone call, operating the television, and retrieving objects. MCI participants showed more searching and task-irrelevant behavior than HC. Task performance was correlated with cognitive status and IADL questionnaires but not with participants’ age. Conclusion: This pilot study showed that smart home technologies offer the chance for an objective and ecologically valid assessment of IADL. It can be analyzed not only whether a task is successfully completed but also how it is completed. Future studies should concentrate on the development of automated detection of IADL deficits.

    Background Most older people wish to age in place, for which functional status or being able to perform activities of daily living (ADLs) is an important precondition. However, along with the substantial growth of the (oldest) old, the number of people who develop limitations in ADLs or have functional decline dramatically increases in this part of the population. Therefore, it is important to gain insight into factors that can contribute to developing intervention strategies at older ages. As a first step, this systematic review was conducted to identify risk and protective factors as predictors for developing limitations in ADLs in community-dwelling people aged 75 and over. Methods Four electronic databases (CINAHL (EBSCO), EMBASE, PsycINFO and PubMed) were searched systematically for potentially relevant studies published between January 1998 and March 2016. Results After a careful selection process, 6,910 studies were identified and 25 were included. By far most factors were examined in one study only, and most were considered risk factors. Several factors do not seem to be able to predict the development of limitations in ADLs in people aged 75 years and over, and for some factors ambiguous associations were found. The following risk factors were found in at least two studies: higher age, female gender, diabetes, hypertension, and stroke. A high level of physical activity and being married were protective in multiple studies. Notwithstanding the fact that research in people aged 65 years and over is more extensive, risk and protective factors seem to differ between the ‘younger’ and ‘older’ olds. Conclusion Only a few risk and protective factors in community-dwelling people aged 75 years and over have been analysed in multiple studies. However, the identified factors could serve both detection and prevention purposes, and implications for future research are given as well. PMID:27760234

    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.

    The purpose of the current study was to establish measurement reliability in adults with Cerebral Palsy (CP), and to examine the feasibility and outcomes of an upper extremity strength training program (three times per week for 90 min each time). A control group design mixed with a prospective time series design for the intervention group was completed, including a pre-test, a post-test after a 12-week intervention period, and a follow-up in the intervention group after an additional 10-week period. Seventeen adults with CP with severe motor impairment took part in the study (10 in the intervention and seven in the control group). The test battery was comprised of wrist and hand dynamometry; dominant hand upper-extremity function measures (Jebsen Hand Function Test=JHFT, Minnesota Manual Dexterity Test=MMDT, and the Nine Hole Peg Test=NHPT); and activity of daily living with the Barthel Index. The results indicated that in both the control and the intervention groups, the strength tests exhibited good-to-excellent reliability during pre-test and post-test. The group comparison revealed that while in the pre-test no between-group differences existed, in the post-test the strength training group demonstrated significantly higher values in five out of eight strength measures, as well as in the MMDT. Discontinuing the program for eight weeks reversed the effects almost to baseline. In conclusion, the outcomes demonstrated the reliability of the assessments utilized in this study, as well as the feasibility of the strength training program, in adults with severe motor impairment due to CP.

    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. PMID:26241869

    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.

    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

    Older women may have chronic or age-related conditions that increase the risk of falls or that limit their ability to remain active. It is unclear if a water-based exercise program provides a safe and effective alternative to land-based exercise. The purpose of this study was to evaluate the impact of a water-based exercise program method on land-based functional activities of daily living (ADL) for women 60 years and older. This study used a quasi- experimental, nonequivalent control group design. Sixty-six women (60-89 yr of age) self- selected to a water exercise (WEX) group (n = 48) or control (C) group (n = 18). The training consisted of a 16-week (45 min·day-1, 3 d·wk-1) supervised WEX program that included 10 min of warm-up and warm down/stretching and 35 min training using the S.W.E.A.T.™ method in shallow water 1.0-1.2 m, with water temperature approximately 28-29°C. Participants were required to attendat least 94% of the sessions. Assessments for participants included ADL functional field tests. In comparison to the C group, WEX participantsimproved (p < 0.05) flexibility (8%), sit- to-stand (31%), walking speed (16%) and stride length (10%), agility (20%), stair climb (22%), arm curl (39%), and static (42-48%) balance, but not dynamic balance. Results indicate that the S.W.E.A.T.™ method applied to this water exercise program provides a well-rounded, safe, and effective exercise program where older women can improve functional ADL and static balance. Key Points Older women with a variety of health conditions participated in 16 weeks of exercise (92% adherence) with no injuries. The S.W.E.A.T.™ method applied to this water-based program was found to significantly improve several aspects of physical function, including postural balance. This shallow water program provided a well-rounded, safe and effective activity for women to improve functional ADL on land. PMID:24421730

    Objective: Investigate efficacy of 13.3 mg/24 h rivastigmine patch in patients with severe Alzheimer’s disease on Alzheimer’s Disease Cooperative Study–Activities of Daily Living Scale–Severe Impairment Version items and domains. Methods: Retrospective analysis of the 24-week, randomized, double-blind ACTivities of daily living and cognitION (ACTION) study, using factor analysis to establish “best fit” for Alzheimer’s Disease Cooperative Study–Activities of Daily Living Scale–Severe Impairment Version items into domains. Treatment differences (13.3 vs 4.6 mg/24 h patch) on items and domains were assessed. Results: Overall, 632 patients provided Alzheimer’s Disease Cooperative Study–Activities of Daily Living Scale–Severe Impairment Version data. Factor analysis yielded four domains. The 13.3 versus 4.6 mg/24 h patch demonstrated significantly greater efficacy on “Daily function” (p = 0.038), supported by greatest effect sizes on items within this domain, and trend toward greater efficacy on “Communication” (p = 0.052). No significant between-group differences were observed on “Independence” (p = 0.600) or “Environment” (p = 0.261). Conclusion: The 13.3 mg/24 h patch was superior to 4.6 mg/24 h patch on “Daily function” in severe Alzheimer’s disease. PMID:26770753

  6. Motion patterns in activities of daily living: 3- year longitudinal follow-up after total shoulder arthroplasty using an optical 3D motion analysis system

    PubMed Central

    2014-01-01

    Background Total shoulder arthroplasty (TSA) can improve function in osteoarthritic shoulders, but the ability to perform activities of daily living (ADLs) can still remain impaired. Routinely, shoulder surgeons measure range of motion (ROM) using a goniometer. Objective data are limited, however, concerning functional three-dimensional changes in ROM in ADLs after TSA in patients with degenerative glenohumeral osteoarthritis. Methods This study included ten consecutive patients, who received TSA for primary glenohumeral osteoarthritis. The patients were examined the day before, 6 months, and 3 years after shoulder replacement as well. We compared them with a control group (n = 10) without any shoulder pathology and measured shoulder movement by 3D motion analysis using a novel 3 D model. The measurement included static maximum values, the ability to perform and the ROM of the ADLs “combing the hair”, “washing the opposite armpit”, “tying an apron”, and “taking a book from a shelf”. Results Six months after surgery, almost all TSA patients were able to perform the four ADLs (3 out of 40 tasks could not be performed by the 10 patients); 3 years postoperatively all patients were able to carry out all ADLs (40 out of 40 tasks possible). In performing the ADLs, comparison of the pre- with the 6-month and 3-year postoperative status of the TSA group showed that the subjects did not fully use the available maximum flexion/extension ROM in performing the four ADLs. The ROM used for flexion/extension did not change significantly (preoperatively 135°-0° -34° vs. 3 years postoperatively 131° -0° -53°). For abduction/adduction, ROM improved significantly from 33°-0° -27° preoperatively to 76° -0° -35° postoperatively. Compared to the controls (118°) the TSA group used less ROM for abduction to perform the four ADLs 3 years postoperatively. Conclusion TSA improves the ability to perform ADL and the individual ROM in ADLs in patients with

    Background: Falling has a great importance among the elderlies. Even if no physical injury occurs, it can cause fear of falling down again and, consequently, reduce older adults’ activities. With regard to the prevalence of falling among older adults, its prevention is essential. Therefore, the present study was aimed to define the effect of need-based education on prevention of older adults’ falling during their everyday life activities. Materials and Methods: This is a quasi-experimental study. Study population comprised all the older adults of age 60 years and over referring to health care centers in Isfahan. Through multiple random sampling, 15 older adults were selected from four health care centers. Data collection tool in the present study was Daily Activity Questionnaire. Results: Results showed a significant difference between the mean of daily activity scores in the intervention group before, immediately after, and 1 month after the intervention (12, 13.6, and 13.5, respectively; P = 0.01). Meanwhile, there was no significant deference between the scores immediately after and 1 month after the intervention. There was no significant difference observed between the three time points in the control group (mean = 12.3; P = 0.907). Conclusion: Implementation of education concerning prevention of older adults’ falling led to improvement of their daily activity in the intervention group. PMID:27563329

  8. Effects of a home visiting nurse intervention versus care as usual on individual activities of daily living: a secondary analysis of a randomized controlled trial

    PubMed Central

    2014-01-01

    Background Home visiting nurses (HVNs) have long been part of home and community-based care interventions designed to meet the needs of functionally declining older adults. However, only one of the studies including HVNs that have demonstrated successful impacts on Activities of Daily Living (ADL) has reported how those interventions affected individual ADLs such as bathing, instead reporting the effect on means of various ADL indices and scales. Reporting impacts on means is insufficient since the same mean can consist of many different combinations of individual ADL impairments. The purpose of our study was to identify which individual ADLs were affected by a specific HVN intervention. Methods This is a secondary analysis comparing two arms of a randomized controlled study that enrolled Medicare patients (mean age = 76.8 years; 70% female) with considerable ADL impairment. At baseline difficulty with individual ADLs ranged from a low of 16.0% with eating to a high of 78.0% with walking. Through monthly home visits, the HVN focused on empowering patients and using behavior change approaches to facilitate chronic disease self-management. Three categories of analyses were used to compare difficulty with and dependence in 6 individual ADLs between the HVN (n = 237) and care as usual (n = 262) groups (total N = 499) at 22 months after study entry: (1) unadjusted analyses that strictly depend on random assignment, (2) multinomial logistic regression analyses adjusting for baseline risk factors, and (3) multinomial regression analyses that include variables reporting post-randomization healthcare use as well as the baseline risk factors. Results Compared to care as usual, patients receiving the HVN intervention had less difficulty performing bathing at 22 months. However, there were no effects for difficulty performing the other 5 ADLs. While no effects were found for lower levels of dependence for any ADLs, impacts were detected for the most

    Spatial neglect has been related to both cortical (predominantly at the temporal-parietal junction) and subcortical (predominantly of the superior longitudinal fasciculus) lesions. The objectives of this observational study were to specify the anatomical relationships of behavioral neglect in activities of daily living (N-ADLs), and the anatomical and psychometric relationships of N-ADLs on one hand and components of neglect (peripersonal neglect and personal neglect) and anosognosia on the other. Forty five patients were analyzed for behavioral difficulties in daily living (on the Catherine Bergego scale) and the main components of neglect (using conventional clinical assessments) during the first months post right hemisphere stroke. Voxel-based lesion-symptom mapping was used to identify brain areas within which lesions explained the severity of bias in each assessment (non-parametric permutation test; p<0.01, one tailed). N-ADLs was associated with lesions centered on the posterior part of the superior temporal gyrus and extending to the temporo-parietal junction, temporo-occipital junction and subcortical white matter (including the superior longitudinal fasciculus). Peripersonal neglect resulted from extended cortical lesions centered on the superior temporal gyrus and the inferior parietal gyrus, with subcortical extension. Personal neglect resulted predominantly from lesions centered on the somatosensory cortex and at a lesser degree on the superior temporal sulcus. Anosognosia resulted from lesions of the posterior inferior temporal gyrus and superior temporal gyrus. In anatomic terms, N-ADLs was strongly related to peripersonal neglect, and those relationships were also shown by the psychometric analysis. In conclusions, superior temporal gyrus and superior longitudinal fasciculus lesions have a pivotal role in N-ADLs. N-ADLs is principally related (anatomically and psychometrically) to peripersonal neglect, and at a lesser degree to anosognosia and

    Recognizing human activities from videos is a fundamental research problem in computer vision. Recently, there has been a growing interest in analyzing human behavior from data collected with wearable cameras. First-person cameras continuously record several hours of their wearers' life. To cope with this vast amount of unlabeled and heterogeneous data, novel algorithmic solutions are required. In this paper, we propose a multitask clustering framework for activity of daily living analysis from visual data gathered from wearable cameras. Our intuition is that, even if the data are not annotated, it is possible to exploit the fact that the tasks of recognizing everyday activities of multiple individuals are related, since typically people perform the same actions in similar environments, e.g., people working in an office often read and write documents). In our framework, rather than clustering data from different users separately, we propose to look for clustering partitions which are coherent among related tasks. In particular, two novel multitask clustering algorithms, derived from a common optimization problem, are introduced. Our experimental evaluation, conducted both on synthetic data and on publicly available first-person vision data sets, shows that the proposed approach outperforms several single-task and multitask learning methods.

    Persons living with HIV/AIDS (PLHA) experience clinically-significant pain as a result of HIV and such pain is often related to increased levels of anxiety/depression. Pain-related anxiety has been identified as a mechanism in the onset and progression of pain experience and associated affective distress. However, there has not been empirical study of pain-related anxiety in relation to affective processes among PLHA. To address this gap, hierarchical multiple regressions were conducted using SPSS v.21 to examine pain-related anxiety (as measured using the Pain Anxiety Symptoms Scale) in relation to anxiety and depressive symptoms (as measured using the Mood and Anxiety Symptoms Questionnaire) among 93 PLHA (10.8% female; Mean age = 49.63, SD = 8.89). Pain-related anxiety was significantly related to anxious arousal symptoms (β = .43) and anhedonic depressive symptoms (β = .25); effects were evident beyond the variance accounted for by CD4 count, race, sex, income level, and current level of bodily pain. The present results suggest that pain-related anxiety may play a role in the experience of anxiety and depressive symptoms among PLHA. PMID:26477684

    Electronic aids to daily living (EADLs) allow persons who have a degenerative neuromuscular condition such as Duchenne's muscular dystrophy to operate a wide variety of household and workplace appliances without assistance (independent of family members or other caregivers). There is very little published research to describe how well EADLs are perceived by users to enhance their sense of personal autonomy, functional independence, and psychological well being. Psychosocial impact is a significant determinant of how users perceive the benefit of assistive devices to their quality of life. This study compared the perceived psychosocial impact of EADLs on a group of device users with the anticipated impact of EADLs reported by a group who were eligible for, but had not yet received, these devices. The perceptions of the user group were measured at two points in time, approximately 6 to 9 months apart, to examine the stability of psychosocial impact. The Psychosocial Impact of Assistive Devices Scale was the instrument used to assess perceived impact. EADLs were found to produce similar degrees of positive impact on users and positive perceptions of anticipated impact on those without devices. The psychosocial impact on users was stable over time. The results indicate that the perceived benefits of EADLs to the autonomy, functional independence, and psychological well being of both users and nonusers are positive and strikingly similar. The study is an important first step in attempting to quantify psychosocial outcomes for EADLs in a way that might facilitate economic analysis of these devices in the future. PMID:11508402

    Rheumatic patients are at risk of social isolation and physical inactivity which can have a significant impact on physical and mental health. Only every seventh patient is organized in a self-help group (SHG), most of them in the German League Against Rheumatism (GLAR). Members of a SHG are socially and physically more active and take part in exercise therapy (ET) more often. Depending on the study, the utilization of ET ranges from 25 % to 71 %. The functional training as the most attended offer of the GLAR showed positive effects at the physical and psychological levels. To motivate difficult to reach patients to engage in self-help and regular exercise, further development of exercise programs with individually tailored intensive strength and endurance elements as well as the increased use of new media seems promising. The Internet provides various opportunities for networking and social participation especially for severely impaired and temporally less flexible patients.

    Clothes represent a unique textile, as they simultaneously provide robustness against our daily activities and comfort (i.e., softness). For electronic devices to be fully integrated into clothes, the devices themselves must be as robust and soft as the clothes themselves. However, to date, no electronic device has ever possessed these properties, because all contain components fabricated from brittle materials, such as metals. Here, we demonstrate robust and soft elastomeric devices where every component possesses elastomeric characteristics with two types of single-walled carbon nanotubes added to provide the necessary electronic properties. Our elastomeric field effect transistors could tolerate every punishment our clothes experience, such as being stretched (elasticity: ∼ 110%), bent, compressed (>4.0 MPa, by a car and heels), impacted (>6.26 kg m/s, by a hammer), and laundered. Our electronic device provides a novel design principle for electronics and wide range applications even in research fields where devices cannot be used.

    We developed a functional semi-structured scale to observe Hemineglect symptoms in Activities of Daily Living (H-ADL). The scale could assist clinicians in assessing rehabilitation priorities aimed at correcting any persisting errors or omissions. In addition, the scale could also be used by caregivers to observe patients' progress and improve their participation. Two groups of right brain-damaged patients (25 with hemineglect; 27 without hemineglect) were tested twice: at admission and before discharge from hospital. A control group of healthy individuals matched to patients for age and education and patients' caregivers also participated. Two raters (A; B), experts in neuropsychology, observed patients and healthy individuals using the H-ADL. We found that the H-ADL final scores correlated with the standard hemineglect tests. The three groups differed in performance and differences also emerged between the first and the second assessment, suggesting an improvement due to the remission of hemineglect as a consequence of the treatment. Raters A and B did not differ in their observations, but there were some discrepancies with caregivers' observations. Therefore, although caregivers could help clinicians in detecting persistent hemineglect behaviour, the assessment should be performed by experts in neuropsychology.

    The ability to perform instrumental activities of daily living (IADL) is important for one's level of independence. A high incidence of limitations in IADL is seen in older adults with intellectual disabilities (ID), which is an important determinant for the amount of support one needs. The aim of this study was to assess the predictive value of physical fitness for the ability to perform IADL, over a 3-year follow-up period, in 601 older adults with ID. At baseline, an extensive physical fitness assessment was performed. In addition, professional caregivers completed the Lawton IADL scale, both at baseline and at follow-up. The average ability to perform IADL declined significantly over the 3-year follow-up period. A decline in the ability to perform IADL was seen in 44.3% of the participants. The percentage of participants being completely independent in IADL declined from 2.7% to 1.3%. Manual dexterity, balance, comfortable and fast gait speed, muscular endurance, and cardiorespiratory fitness were significant predictors for a decline in IADL after correcting for baseline IADL and personal characteristics (age, gender, level of ID, and Down syndrome). This can be interpreted as representing the predictive validity of the physical tests for a decline in IADL. This study shows that even though older adults with ID experience dependency on others due to cognitive limitations, physical fitness also is an important aspect for IADL, which stresses the importance of using physical fitness tests and physical fitness enhancing programs in the care for older adults with ID.

    2011-01-01

    Background The proportion of older people is increasing rapidly in Vietnam. The majority of the elderly live in rural areas. Their health status is generally improving but this is less pronounced among the most vulnerable groups. The movement of young people for employment and the impact of other socioeconomic changes leave more elderly on their own and with less family support. This study aims to assess the daily care needs and their socioeconomic determinants among older people in a rural setting. Methods In 2007, people aged 60 years and older, living in 2,240 households, were randomly selected from the FilaBavi Demographic Surveillance System (DSS). They were interviewed using structured questionnaires to assess needed support in activities of daily living (ADLs). Individuals were interviewed about the presence of chronic illnesses that had been diagnosed by a physician. Participant socioeconomic characteristics were extracted from the FilaBavi repeat census. The repeat census used a repeat of the same survey methods and questions as the original FilaBavi DSS. Distributions of study participants by socioeconomic group, supports needed, levels of support received, types of caregivers, and the ADL index were described. Multivariate analyses were performed to identify socioeconomic determinants of the ADL index. Results The majority of older people do not need of support for each specific ADL item. Dependence in instrumental or intellectual ADLs was more common than for basic ADLs. People who need total help were less common than those who need some help in most ADLs. Over three-fifths of those who need help receive enough support in all ADL dimensions. Children and grandchildren are the main caregivers. Age group, sex, educational level, marital status, household membership, working status, household size, living arrangement, residential area, household wealth, poverty status, and chronic illnesses were determinants of daily care needs in old age.

    Background: Oral conditions are known to affect various aspects of quality of life. Similarly, the social consequence of the quality of life in the day to day living is also equally important. Several studies have quantified the social consequences of diseases through activity limitations in people's daily living. The instruments which cover a broad spectrum of life are proposed to be compared with the clinical oral hygiene status of people from different social classes. Aim: To assess the validity of dental impact on daily living (DIDL) questionnaire measuring subjective dental problems and their impact in the day to day life among tribes of Wayanad. Study Design: Cross-sectional. Materials and Methods: DIDL questionnaire developed by Leao and Sheiham was used. We recorded the clinical oral health status using decayed, missing, filled, simplified oral hygiene index, and community periodontal index indices, to correlate the subjective findings of dental impact tribe to obtain construct validity of the questionnaire. Analysis: Descriptive statistics and Spearman's correlation using IBM SPSS software version 20. Results: In the study population of 250 participants, the majority of the participants were from the age group between 36 and 50 years (40%) and females were in the majority (64%). The clinical status of the participants was poor in the majority while their perceived impact in their day to day living was found to be relatively satisfied. The study results show the DIDL tool had weak validity in relation to the clinical status with relevance to the social status of Indian tribal population. Conclusion: The study result shows that there was insignificant and weak validity between the DIDL tool and the oral health status among these tribes who were from a low social class. This might be because their priority in life which is different from what a person from high social class. So the dental problem is ignored at the level of individual depending on his

    Geriatric patients with dementia and hypertension (DAH) suffer both physically and financially. The needs of these patients mainly include improving the quality of daily living and reducing the cost of long-term care. Traditional treatment approaches are strained to meet these needs. The goal of the paper is to design an innovative system to provide cost-effective quality treatments for geriatric patients with DAH by collecting and analyzing the multi-dimensional personal information, such as observations in daily living (ODL) from a non-clinical environment. The proposed ODLs in paper include activities, cleanliness, blood pressure, medication compliance and mood changes. To complete the system design, an incremental user-centered strategy is exploited to assemble needs of patients, caregivers, and clinicians. A service-oriented architecture (SOA) is employed to make full use of existing devices, software systems, and platforms. This health-related knowledge can be interpreted and utilized to help patients with DAH remain in their homes safely and improve their life quality while reducing medical expenditures.

    2004-01-01

    This study investigated the experience of seven new users of a particular type of assistive technology through the stages of anticipating, acquiring, and using an electronic aid to daily living. A mixed methods research approach was used to explore each of these stages. The Psychosocial Impact of Assistive Devices Scale was used to measure the perceived impact of the new assistive technology on users' quality of life, and findings were further explored and developed through open-ended questioning of the participants. Results indicated that preacquisition of the device, users predicted that the electronic aid to daily living would have a positive impact on their feelings of competence and confidence and that the device would enable them in a positive way. One month after acquiring the device a reduced, yet still positive, impact was observed. By 3 and 6 months after acquisition, perceived impact returned to the same positive high level as preacquisition. It is suggested that prior to receiving the device, potential users have positive expectations for the device that are not based in experience. At the early acquisition time, users adjust expectations of the role of the assistive technology in their lives and strive to balance expectations with reality. Three to 6 months after acquiring an electronic aid to daily living, the participants have a high positive view of how the device impacts on their lives based in experience and reality. A model illustrating the electronic aids to daily living acquisition process is proposed, and suggestions for future study are provided.

    The effectiveness and efficiency (training trials and training errors through criterion) of stimulus fading, stimulus shaping, time delay, and a feedback only procedure were compared in teaching three adults with moderate developmental delays sight words encountered in activities of daily living. In Experiment 1, the four procedures were assessed during training in a controlled environment to identify the most effective and efficient procedure for each participant. All three adults acquired the target words, and the four procedures were found to be of comparable efficiency in total training sessions, whereas individual differences were found in training errors to criterion. In Experiment 2, the feedback only procedure was used to teach the three participants sight words in community settings. Participants learned new words in the community settings and used the previously trained words in daily living activities. The benefit of conducting a preliminary evaluation of instructional procedures during controlled training is discussed. PMID:8469800

    Daily living skills standard scores on the Vineland Adaptive Behavior Scales-2nd edition were examined in 417 adolescents from the Simons Simplex Collection. All participants had at least average intelligence and a diagnosis of autism spectrum disorder. Descriptive statistics and binary logistic regressions were used to examine the prevalence and predictors of a "daily living skills deficit," defined as below average daily living skills in the context of average intelligence quotient. Approximately half of the adolescents were identified as having a daily living skills deficit. Autism symptomatology, intelligence quotient, maternal education, age, and sex accounted for only 10% of the variance in predicting a daily living skills deficit. Identifying factors associated with better or worse daily living skills may help shed light on the variability in adult outcome in individuals with autism spectrum disorder with average intelligence.

    Full-dose prophylaxis treatment for persons with haemophilia is not affordable in China due to its economic constraints, particularly in adults requiring higher clotting factor (CFC) doses. Low-dose tertiary prophylaxis for adults with severe haemophilia A (SHA) in Beijing became feasible and implemented when government insurance covering 85% CFC cost in Beijing began in December 2009. The aim of this study was to evaluate the benefits of low-dose tertiary prophylaxis in SHA adults. Analysis of data on 33 patients on low-dose tertiary prophylaxis (5-10 IU/kg, two to three times per week) at the Haemophilia Treatment Center, Peking Union Medical College Hospital between December 2009 and December 2013. The 33 patients (age 18-60 years, mean 33.4) were on prophylaxis for 20.8 ± 9.9 months (compared with prior on-demand therapy for 20.0 ± 11.7 months). Prophylaxis resulted in significant decrease in annual bleeding rate (ABR, 11.8 ± 7.6 vs. 41.5 ± 20.7, 71.1% reduction, P < 0.0001), and significant improvement in Functional Independence Score in Haemophilia (FISH) measurement reflecting improvement in self-care and mobility. Radiologic (Pettersson) joint score was neither improved nor deteriorated. Ten of the 33 patients originally wheel chair and bed-bound began to walk and function independently in their daily lives. Low-dose tertiary prophylaxis for adults with SHA in China is feasible and beneficial. Although the average ABR remained high, a significant improvement in self-care and mobility measured by FISH was observed. These promising clinical experiences form the basis for further formal studies with more defined therapeutic protocol and outcome measures for affordable prophylaxis regimens in haemophilia adults in China.

    Daily activity levels were investigated as related to sleep quality in young adult college students aged 18 to 30 years. 85 participants (20 men, 65 women) completed the Young Adult Daily Activity Scale (YADAS). This 37-item checklist has 34 items based on focus group discussion points of college students' typical daily activities and three blank items for students to include their daily activities if not in the listing. The tabulation of type and amount of waking daily activities represents a unique measurement of factors that may affect sleep quality. The participants also rated their typical sleep quality using a standard 5-point scale (low indicating poor sleep). Correlations of sleep ratings and activities were not significant. PMID:21667753

    Balance control probably has the greatest impact on independence in activities of daily living (ADL), because it is a fundamental motor skill and prerequisite to the maintenance of a myriad of postures and mobile activities. We propose a new rehabilitation therapy to administer standing and mobile balance control training, enabled by a Mobile Robotic Assistive Balance Trainer (MRABT). The targeted group for this initial work is post stroke patients, although it can be extended to subjects with other neurological insults in the future. The proposed system consists of a mobile base and a parallel robotic arm which provides support to the patient at the hip. The compliant robotic arm with intelligent control algorithm will only provide support and assistance to the patient when the center of mass of the body deviates beyond the predefined safety boundary, mimicking the helping hands of a parent when a toddler learns to walk. In this paper, we present our initial work in the design and kinematic analysis of the system. PMID:25571190

    Daily living skills (DLS), such as personal hygiene, meal preparation, and money management, are important to independent living. Research suggests that many individuals with autism spectrum disorder exhibit impairments in daily living skills relative to their cognitive skills. This study examined predictors of daily living skills attainment and trajectories of daily living skills in a longitudinal sample referred for possible autism spectrum disorder and followed from 2 to 21 years of age. Consistent with previous studies, participants with autism spectrum disorder and nonspectrum diagnoses showed continual development of daily living skills throughout childhood and adolescence. Early childhood nonverbal mental age was the strongest predictor of daily living skills attainment for both diagnostic groups. Group-based modeling suggested two distinct trajectories of daily living skills development for participants with autism spectrum disorder. Skill levels for both groups of young adults with autism spectrum disorder remained considerably below age level expectations. Whereas the "High-DLS" group gained approximately 12 years in daily living skills from T2 to T21, the "Low-DLS" group's daily living skills improved 3-4 years over the 16- to 19-year study period. Nonverbal mental age, receptive language, and social-communication impairment at 2 years predicted High- versus Low-DLS group membership. Receiving greater than 20 h of parent-implemented intervention before age 3 was also associated with daily living skills trajectory. Results suggest that daily living skills should be a focus of treatment plans for individuals with autism spectrum disorder, particularly adolescents transitioning to young adulthood.

    Previous studies of Huntington's disease (HD) have reported motor control deficits for selected fine and gross motor skills. However, no studies have metrically assessed postural control in this clinical group when performing motor skills involved in daily living. Therefore, the purpose of the present study was to evaluate and compare postural control of individuals with confirmed Huntington's disease and non-gene carriers when completing three functional postural tasks. Eleven individuals with HD (mean age=47.1 years: UHDRS mean=34.5: mean age of HD onset 34.6 years: mean CAG repeat=44.1) and 17 non-gene carriers (NGC) (mean age=39.2 years: UHDRS mean=0.13: mean CAG repeat=20.5) completed three tests on a force plate interfaced with a computer. The tests were a step up and over an obstacle (SUO) test, a sit-to-stand (STS) test, and a step and turn (ST) test. Selected kinematic and kinetic variables were used to quantify postural control. Data were analyzed using MANOVA procedures and discriminant function analysis. HD patients were significantly slower in completing all three tests (HD SUO=2.3 s vs. NGC SUO=1.6 s; HD STS=0.8 s vs. NGC STS=0.5 s; HD ST=1.7 s vs. NGC ST=0.9 s) and developed less rising force during the step up and over test (HD=25.8% body weight vs. NGC=39.4% body weight) but not for the sit-to-stand test. Additionally, sway velocity of the center of gravity (COG) was significantly higher for HD patients when performing the sit-to-stand (HD=4.1°/s vs. NGC=2.9°/s) and step and turn tests (HD=33.7°/s vs. NGC=21.7°/s). HD patients manifest significant postural control deficits when performing motor skills typical of daily living activities. PMID:21256027

    2013-08-01

    The present study examined the situations and conditions in which ruminative self-focus is less likely to occur in daily life. Previous researchers have described a mood-brightening effect of depression, where depressed individuals exhibit greater positive emotional reactivity to positive daily events than do nondepressed individuals. To better understand this paradoxical effect, we investigated the moderating role of depression in the relationship between daily activities and ruminative thinking. Forty-one Japanese undergraduates (9 women and 32 men) recorded their thought contents and the type and subjective appraisals of activities that they engaged in 8 times a day for a week at semirandom intervals. Multilevel modeling analyses indicated that subjectively pleasant activities were associated with improved mood states and reduced ruminative thinking. However, some of these associations were moderated by depressive symptoms, suggesting that individuals with higher levels of depression showed a greater reduction of ruminative thinking during pleasant activities. These results imply that daily activities are important for reducing rumination, particularly for individuals with higher levels of depression, and that the brightening effect of depression is evident for cognitive as well as emotional activities. The cognitive basis of this paradoxical effect is discussed. PMID:23527502

  13. Age Differences in Daily Social Activities

    PubMed Central

    Marcum, Christopher Steven

    2014-01-01

    The extent to which older and younger people do different activities when they are with others and when they are alone is examined in this article. I leverage interpersonal data in combination with information on activities from the American Time Use Survey to shed light on the long held finding that older people have less social contact than younger people. The results show that, net of intervening factors, age is associated with declines in time spent with others for virtually all types of time use. However, the variety of activities that older and younger people do also differs. Using leisure activities to probe this finding reveals that, when older people spend time with others it tends to be during activities that are sui generis social activities—such as attending parties—but that this is not necessarily the case for younger people. The literature on time use and aging is discussed in light of these findings and a new hypothesis on agency in the life course is proposed. PMID:25190898

    2015-01-01

    Self-conscious emotions play a role in regulating daily achievement strivings, social behavior, and health, but little is known about the processes underlying their daily manifestation. Emerging adults (n = 182) completed daily diaries for eight days and multilevel models were estimated to evaluate whether, how much, and why their emotions varied from day-to-day. Within-person variation in authentic pride was normally-distributed across people and days whereas the other emotions were burst-like and characterized by zero-inflated, negative binomial distributions. Perceiving social interactions as generally communal increased the odds of hubristic pride activation and reduced the odds of guilt activation; daily communal behavior reduced guilt intensity. Results illuminated processes through which meaning about the self-in-relation-to-others is constructed during a critical period of development. PMID:25859164

    2015-08-01

    The ability to accurately recognize daily activities of residents is a core premise of smart homes to assist with remote health monitoring. Most of the existing methods rely on a supervised model trained from a preselected and manually labeled set of activities, which are often time-consuming and costly to obtain in practice. In contrast, this paper presents an unsupervised method for discovering daily routines and activities for smart home residents. Our proposed method first uses a Markov chain to model a resident's locomotion patterns at different times of day and discover clusters of daily routines at the macro level. For each routine cluster, it then drills down to further discover room-level activities at the micro level. The automatic identification of daily routines and activities is useful for understanding indicators of functional decline of elderly people and suggesting timely interventions.

    2016-06-25

    Physical activity improves glycemic control and reduces the risk of cardiovascular disease (CVD) and mortality in patients with type 2 diabetes (T2D). Moderate to vigorous physical activity is recommended to manage T2D; however, patients with T2D can be physically weak, making it difficult to engage in the recommended levels of physical activity. Daily physical activity includes various activities performed during both occupational and leisure time such as walking, gardening, and housework that type 2 diabetic patients should be able to perform without considerable physical burden. This review focuses on the association between daily physical activity and T2D. Walking was the most common form of daily physical activity, with numerous studies demonstrating its beneficial effects on reducing the risk of T2D, CVD, and mortality. Walking for at least 30 min per day was shown to reduce the risk of T2D by approximately 50%. Additionally, walking was associated with a reduction in mortality. In contrast, evidence was extremely limited regarding other daily physical activities such as gardening and housework in patients with T2D. Recent studies have suggested daily physical activity, including non-exercise activity thermogenesis, to be favorably associated with metabolic risks and mortality. However, well-designed longitudinal studies are warranted to elucidate its effects on overall health. PMID:27350847

    [Purpose] The purpose of this study was to evaluate the relationships between daily activities, information processing, and motor skills in individuals with hemineglect after having a left hemiparetic stroke. [Subjects and Methods] The instrumental activities of daily living of 35 patients (22 male and 13 female; age: 57.1 ± 16.9 years) with hemineglect after having a left hemiparetic stroke were assessed by using three clinical measurement tools, including activity card sorting, assessment of motor and process skills, and the modified Barthel Index. [Results] The results of the regression analysis indicated that the patients’ processing skills in instrumental activities of daily living after having a left hemiparetic stroke were reduced. Participation in leisure and social activities was also affected as assessed by using the modified Barthel Index. [Conclusion] This study supports the clinical need for rehabilitation intervention after a left hemiparetic stroke to improve patients’ processing skills and independence in performing activities of daily living.

    Objective The aim of this work was to describe the development and psychometric analysis of the Penn Parkinson's Daily Activities Questionnaire. The questionnaire is an item response theory-based tool for rating cognitive instrumental activities of daily living in PD. Methods Candidate items for the Penn Parkinson's Daily Activities Questionnaire were developed through literature review and focus groups of patients and knowledgeable informants. Item selection and calibration of item-response theory parameters were performed using responses from a cohort of PD patients and knowledgeable informants (n = 388). In independent cohorts of PD patients and knowledgeable informants, assessments of test-retest reliability (n = 50), and construct validity (n = 68) of the questionnaire were subsequently performed. Construct validity was assessed by correlating questionnaire scores with measures of motor function, cognition, an existing activities of daily living measure, and directly observed daily function. Results Fifty items were retained in the final questionnaire item bank. Items were excluded owing to redundancy, difficult reading level, and when item-response theory parameters could not be calculated. Test-retest reliability was high (intraclass correlation coefficient = 0.97; P < 0.001). The questionnaire correlated strongly with cognition (r = 0.68; P < 0.001) and directly observed daily function (r = 0.87; P < 0.001), but not with motor impairment (r = 0.08; P = 0.53). The questionnaire score accurately discriminated between PD patients with and without dementia (receiver operating characteristic curve = 0.91; 95% confidence interval: 0.85–0.97). Conclusions The Penn Parkinson's Daily Activities Questionnaire shows strong evidence of reliability and validity. Item response theory-based psychometric analysis suggests that this questionnaire can discriminate across a range of daily functions. PMID:26249849

    To test the circadian clock characteristics, activity behaviour of male blackheaded munia was recorded. Two experiments were performed. In experiment 1A, activity of munia was recorded under long days, LD (14L: 10D); and short days, SD (10L: 14D). Locomotor activity of two groups of munia exposed to equinox (12L: 12D) daylength followed by transfer of one group each to continuous dimlight (DD) and continuous bright light (LL) was recorded in experiment 1B. Experiment 2 aimed to describe seasonal trend in daily pattern of activity/rest cycle under natural illumination conditions (NDL). Hourly activity during daytime was more under SD than under LD. Munia did not exhibit bimodality in daily activity pattern; activity during morning, M (2h) was more than evening, E. A free-running activity rhythm was recorded in munia under DD; the same was arrhythmic under LL. The seasonal pattern in daily activity profiles under NDL corresponds to the seasonal changes in daylength. Daylength regulates daily and seasonal activity patterns in blackheaded munia.

    Social-cognitive theories, such as the theory of planned behavior, posit intentions as proximal influences on physical activity (PA). This paper extends those theories by examining within-person variation in intentions and moderate-to-vigorous physical activity (MVPA) as a function of the unfolding constraints in people's daily lives (e.g., perceived time availability, fatigue, soreness, weather, overeating). College students (N = 63) completed a 14-day diary study over the Internet that rated daily motivation, contextual constraints, and MVPA. Key findings from multilevel analyses were that (1) between-person differences represented 46% and 33% of the variability in daily MVPA intentions and behavior, respectively; (2) attitudes, injunctive norms, self-efficacy, perceptions of limited time availability, and weekend status predicted daily changes in intention strength; and (3) daily changes in intentions, perceptions of limited time availability, and weekend status predicted day-to-day changes in MVPA. Embedding future motivation and PA research in the context of people's daily lives will advance understanding of individual PA change processes. PMID:24197717

    This paper explores wellbeing from the perspective of the psychological dynamics underlying adolescents' relationship with place. It uses a dynamic model of wellbeing called personal project analysis (PPA) which captures the concept of 'flourishing', defined as functioning well in your activities, strivings and interactions with the world [1]. Using PPA methods we identified adolescents' daily activities and the 'restorative niches' that best support them. A series of settings (including home, urban and natural outdoor places) were explored using PPA with 45 young people (aged 11-13) living in Edinburgh, Central Scotland. Participants were asked to think of eight projects of current importance to them, to say where the project took place and to rate each project against a series of core wellbeing dimensions measuring project meaning, manageability, support and affect (how much fun, stress etc.). Latent class analysis was carried out to explore clusters-or sub-groups-in the data and to identify the significant discriminators between clusters. A three-cluster model produced the best fit with project type, project place and wellbeing indicators (fun and stress) significantly discriminating between the three clusters. The three clusters were labeled by their dominant environmental context, 'faraway' (e.g., beach, national parks, hills), 'everyday' (e.g., home, school, local streets) and 'citywide' (e.g., sport settings, urban town context). 'Faraway' and 'citywide' clusters had a significantly higher wellbeing content, especially for fun and stress; the 'everyday' cluster indicated local environs remain a dominant project place for this age group, but are associated with greater stress. We compare findings with adults and suggest that outdoor settings further afield from home have greater significance within adolescent project systems, but that support is needed to facilitate access to these places.

    This paper describes a flexible, cost-effective, wireless in-home activity monitoring system for assisting patients with cognitive impairments due to traumatic brain injury (TBI). The system locates the subject with fixed home sensors and classifies early morning bathroom activities of daily living with a wearable wireless accelerometer. The system extracts time- and frequency-domain features from the accelerometer data and classifies these features with a hybrid classifier that combines Gaussian mixture models and a finite state machine. In particular, the paper establishes that despite similarities between early morning bathroom activities of daily living, it is possible to detect and classify these activities with high accuracy. It also discusses system training and provides data to show that with proper feature selection, accurate detection and classification are possible for any subject with no subject specific training.

    Objective In contrast to proposals that physical activity (PA) can be a substitute for alcohol use, people who engage in greater overall PA generally consume more alcohol on average than less-active peers. Acknowledging that both PA and alcohol use vary considerably from day-to-day, this study evaluated whether established associations reflect daily behavioral coupling within-person, are an artifact of procedures that aggregate behavior over time, or both. Methods A lifespan sample of 150 adults (aged 19–89 years) completed three 21-day measurement bursts of a daily diary study. At the end of each day, they reported on their PA and alcohol consumption. Data were analyzed in a negative binomial multilevel regression. Results As expected, both behaviors exhibited limited between-person variation. After controlling for age, sex, and seasonal and social calendar influences, daily deviations in PA were significantly associated with daily total alcohol use. Once the within-person process linking PA and alcohol use was controlled, usual PA and total alcohol use were not associated. Conclusions The established between-person association linking PA and alcohol use reflects the aggregation of a daily process that unfolds within-people over time. Further work is needed to identify mediators of this daily association and to evaluate causality, as well as to investigate these relations in high-risk samples. PMID:25222084

    Circadian rhythms reflect extensive programming of biological activity that meets and exploits the challenges and opportunities offered by the periodic nature of the environment. In the present investigation, we recorded the total activity of athletic horses kept at four different times of the year (vernal equinox, summer solstice, autumn equinox and winter solstice), to evaluate the presence of seasonal variations of daily activity rhythms. Athletic Thoroughbred horses were kept in individual boxes with paddock. Digitally integrated measure of total activity of each mare was continuously recorded by actigraphy-based data loggers. Horse total activities were not evenly distributed over the day, but they were mainly diurnal during the year. Daily activity rhythms showed clear seasonal variations, with the highest daily amount of activity during the vernal equinox and the lowest during the winter solstice. Interestingly, the amount of activity during either photophase or scotophase changed significantly throughout the year. Circadian analysis of horse activities showed that the acrophase, the estimated time at which the peak of the rhythm occurs, did not change during the year, it always occurred in the middle of the photoperiod. Analysing the time structure of long-term and continuously measured activity and feeding could be a useful method to critically evaluate athletic horse management systems in which spontaneous locomotor activity and feeding are severely limited. Circadian rhythms are present in several elements of sensory motor and psychomotor functions and these would be taken into consideration to plan the training schedules and competitions in athletic horses.

    Local governments in Europe have a vital role in promoting physical activity in the daily life of citizens. However, explicit investment in active living has been limited. One of the four core themes for Phase IV (2003-2008) of the World Health Organization (WHO) European Healthy Cities Network (WHO-EHCN) was to encourage local governments and their partners to implement programs in favor of active living. This study analyzes the performance of network cities during this period. Responses to a general evaluation questionnaire are analyzed by content according to a checklist, and categorized into themes and dimensions. Most cities viewed "active living" as an important issue for urban planning; to improve visual appeal, enhance social cohesion, create a more sustainable transport system to promote walkability and cyclability and to reduce inequalities in public health. Almost all member cities reported on existing policies that support the promotion of active living. However, only eight (of the 59) responding cities mentioned an integrated framework specific for active living. Many efforts to promote active living are nested in programs to prevent obesity among adults or children. Future challenges include establishing integrated policies specifically for active living, introducing a larger range of actions, as well as increasing funding and capacity to make a difference at the population level.

    Night eating syndrome (NES) is a delayed pattern of energy intake. It is unknown if symptoms associated with this syndrome are accompanied by a delayed pattern of physical activity. This study examines the relationship between physical activity patterns and delayed eating behaviors in children. Children from the QUALITY cohort (n = 269, 45% female, aged 8-11 y) completed the Night Eating Questionnaire (NEQ), which measures NES symptoms on a continuous scale and identifies single NES symptoms. Daily accelerometer data were transformed into mean counts per wear-time minute for each hour of the day. Children with high NEQ scores had higher levels of daily (p < 0.001) and evening physical activity (p = 0.05) and reached 75% of their total daily physical activity 20 minutes later than children with low NEQ scores (p < 0.05). Excessive evening snacking and a strong urge to eat in the evening or at night were the symptoms most related to these physical activity patterns. Children with delayed eating behaviors had higher levels of physical activity in the late morning and evening and a delayed physical activity pattern compared to children with no or fewer symptoms. Future research is needed to determine if physical activity plays a role in the onset or maintenance of night eating.

    Self-sufficiency is central to child and family well-being. This report focuses on predictors of adaptive daily living skills (DLS) development in young children with ASD and whether DLS gains predict decreases in parenting stress. Participants were 162 toddlers with ASD and their parents, assessed at 3 annual timepoints. Hierarchical Linear Models showed that age, DQ, and autism symptom severity uniquely predicted initial DLS and DLS growth. Child problem behaviors predicted initial DLS only. DLS was associated with change in parenting stress above and beyond DQ, autism symptom severity, and problem behaviors. Children with lower IQ and more severe symptoms showed slower DLS gains. Given its relation to parenting stress, DLS are an important intervention target in young children with ASD. PMID:21598046

    Sensori-motor development and performance of daily living skills (DLS) remain little explored in children with autism spectrum disorders (ASD). The objective of this study was to determine the impact of sensori-motor skills on the performance of DLS in preschool children with ASD. Thirty-five children, 3-4 years of age, were recruited and assessed with a battery of diagnostic and clinical tests. Children showed atypical sensory responses, very poor motor and DLS. Sensory avoiding, an excessive reaction to sensory stimuli, and fine motor skills were highly correlated with DLS, even when cognitive performance was taken into account. Sensori-motor deficits have an impact on the autonomy of children with ASD and interventions should aim at improving and supporting the development of sensori-motor skills.

    We explored whether exposure to tobacco outlets in youths' broader activity spaces differs from that obtained using traditional geographic measures of exposure to tobacco outlet within buffers around homes and schools. Youths completed an initial survey, daily text-prompted surveys, and carried GPS-enabled phones for one week. GPS locations were geocoded and activity spaces were constructed by joining sequential points. We calculated the number of tobacco outlets around these polylines and around homes and schools. Results suggest that activity spaces provide a more accurate measure of tobacco outlet exposures than traditional measures. Assessing tobacco outlet exposure within activity spaces may yield significant information to advance the field.

    Social Interaction and the feeling of emotional closeness to beloved ones is mainly driven by the communication with each other. For patients suffering from a serious disease due to intense mood changes, it is difficult to keep regular contact with relatives. This affects the need for direct and verbal communication with relatives. To continue the participation in each others lives, we have developed a concept to share daily activities, current moods and presence information using a smart living room table. A first lab study with a prototype showed promising results with regard to expressiveness, joy of use, and usability. PMID:27534325

  14. Impacts of vigorous and non-vigorous activity on daily energy expenditure.

    PubMed

    Westerterp, Klaas R

    2003-08-01

    Activity intensity is a potential determinant of activity-induced energy expenditure. Tri-axial accelerometery is the most objective measurement technique for the assessment of activity intensity, in combination with doubly-labelled water for the measurement of energy expenditure under free-living conditions. Data on the effects of subject characteristics, including body size and age, and exercise training on the relationship between activity intensity and daily energy expenditure are reviewed. Average daily metabolic rate and non-basal energy expenditure are positively related to body size. The duration and intensity of physical activities do not need to be equivalent to the energy spent on activity. Obese subjects spend more energy on physical activity but can perform fewer activities, especially high-intensity (weight-bearing) activities, because of their higher body weight. Physical activity generally declines gradually from about 60 years of age onwards. Most subjects > 80 years have an activity level well below the level defined for sedentary middle-aged adults. Spending relatively more time on low-intensity activities has a negative effect on the mean physical activity level. To obtain a higher physical activity level does not necessarily imply high-intensity activities. In an average subject 25% of the activity-induced energy expenditure may be attributed to high-intensity activities. Exercise training, as a form of high-intensity activity, affects the physical activity level more in younger subjects than in elderly subjects.

    Musculoskeletal forces generated by normal daily activity on Earth maintain the functional and structural properties of muscle and bone throughout most of one's adult life. A reduction in the level of cumulative daily loading caused by space flight, bed rest or spinal cord injury induces rapid muscle atrophy, functional changes in muscle, and bone resorption in regions subjected to the reduced loading. Bone cells in culture and bone tissue reportedly respond to a wide variety of non-mechanical and mechanical stimuli ranging, from electromagnetic fields, and hormones to small amplitude, high frequency vibrations, fluid flow, strain rate, and stress/strain magnitude. However, neither the transduction mechanism that transforms the mechanical input into a muscle or bone metabolic response nor the characteristics, of the loading history that directly or indirectly stimulates the cell is known. Identifying the factors contributing to the input stimulus will have a major impact on the design of effective countermeasures for long duration space flight. This talk will present a brief overview of current theories of bone remodeling and functional adaptation to mechanical loading. Work from our lab will be presented from the perspective of daily cumulative loading on Earth and its relationship to bone density and structure. Our objective is to use the tibia and calcaneus as model bone sites of cortical and cancellous bone adaptation, loaded daily by musculoskeletal forces in equilibrium with the ground reaction force. All materials that will be discussed are in the open scientific literature.

    1996-12-01

    Patients with chronic obstructive pulmonary disease (COPD) frequently develop nocturnal oxygen desturation because of alveolar hypoventilation, worsening of ventilation-perfusion mismatch, and sometimes obstructive sleep apnoeas. In contrast, little is known about their oxygen status during the various activities of daily life. The aim of this study was to compare the oxygen saturation profile during day and night, and to assess the influence of different daily activities in COPD. During a rehabilitation programme, we studied 30 patients with moderate-to-severe COPD (median forced expiratory volume in one second (FEV1) 37% of predicted), without marked hypoxaemia (median arterial oxygen tension (Pa,O2) 9.1 kPa). Arterial oxygen saturation (Sa,O2) was assessed by pulse oximetry during night (8 h) and day (10.5 h). The mean and minimal Sa,O2 were calculated, and desaturations were defined as Sa,O2 falls > 4%.h-1. Daily activities were identified by the patients as resting, eating, washing, nebulization therapy and walking. Mean Sa,O2 was lower during the night (88%) than during the day (89%). In contrast, minimal Sa,O2 was lower during the day (69%) than during the night (72%), and the number of desaturations was higher during the day (8.6 desaturations.h-1) than during the night (6.8 desaturations.h-1). Mean Sa,O2 was 88% during walking, which was lower than during resting (90%), nebulization (90%), and meals (89%). The number of desaturations was higher during walking (13.1 desaturations.h-1), washing (12.6 desaturations.h-1), and eating (9.2 desaturations.h-1) than during resting (5.3 desaturations.h-1). We conclude that daily activities, such as walking, washing and eating, are associated with transient oxygen desaturation in patients with moderate-to-severe chronic obstructive pulmonary disease, even without marked resting hypoxaemia.

    The links between youth’s daily activities and adjustment and the role of cultural practices and values in these links were studied in 469 youth from 237 Mexican American families. In home interviews, data on mothers’, fathers’, and two adolescent-age siblings’ cultural practices (language use, social contacts) and values (for familism, for education achievement) were collected, along with data on youth risky behavior and depressive symptoms. In 7 nightly phone calls, youth reported on their day’s free time activities (i.e., sports, academics, religious activities, television viewing, and hanging out). Analyses revealed that youth who spent more time in unsupervised hanging out reported more depressive symptoms and risky behavior, and those who spent more time in academic activities reported less risky behavior. Results also indicated that more Anglo-oriented youth spent more time in sports, that more Mexican-oriented youth spent more time watching television, that fathers’ familism values were related to youth’s time in religious activities, and that parents’ educational values were linked to youth’s time in academic activities. Some evidence indicated that parents’ cultural practices and values, particularly fathers’, moderated the links between daily activities and youth adjustment. PMID:19636760

    2006-01-01

    There is growing evidence that social rhythms (e.g., daily activities such as getting into or out of bed, eating, and adhering to a work schedule) have important implications for sleep. The present study used a prospective measure of daily activities to assess the relation between sleep and social rhythms. College students (n=243) 18 to 39 yrs of age, completed the Social Rhythm Metric (SRM) each day for 14 d and then completed the Pittsburgh Sleep Quality Index (PSQI). The sample was divided into groups of good or poor sleepers, according to a PSQI cut-off score of 5 points and was compared on the regularity, frequency, timing, and extent of social engagement during activities. There was a lower frequency and less regularity of social rhythms in poor sleepers relative to good sleepers. Good sleepers engaged more regularly in activities with active social engagement. Earlier rise time, first consumption of a beverage, going outdoors for the first time, and bedtime were associated with better sleep. Greater variability in rise time, consuming a morning beverage, returning home for the last time, and bedtime were associated with more disturbed sleep. The results are consistent with previous findings of reduced regularity in bedtime and rise time schedules in undergraduates, other age groups, and in clinical populations. Results augment the current thought that regulating behavioral zeitgebers may be important in influencing bed and rise times, and suggest that engaging in activities with other people may increase regularity.

    The activity and temperature rhythms of pig-tailed macaques (Macaca nemestrina) maintained in LD 16:8 at 25 C in specially designed restraint chairs have been examined. Activity was monitored via a sensor that was attached to the restraint chair. Temperature was monitored at the axilla, ankle and ear. All variables showed prominent day-night variations, and except for ankle temperature, had highest values during the daytime. These results show that the regulation of the daily rhythm of body temperature involves anatomical sites that are utilized in a temporally distinct fashion.

    Physical activity is considered a valuable tool for enhancing life satisfaction. However, the processes linking these constructs likely differ across the adult life span. In older adults the association between physical activity and life satisfaction appears to involve usual levels of physical activity (i.e., a between-person association driven by differences between more and less active people). In younger adults the association has consistently been based on day-to-day physical activity (i.e., a within-person association driven by differences between more and less active days). To resolve this inconsistency, a daily diary study was conducted with a life span sample of community-dwelling adults (age 18-89 years; N = 150) over three 21-day measurement bursts. Usual physical activity was positively associated with life satisfaction in middle and older adulthood; however, this association was not present in young adulthood. When present, this between-person association was mediated by physical and mental health. A within-person association between physical activity and life satisfaction was also present (and did not differ across age). Generally, on days when people were more physically active then was typical for them, they experienced greater life satisfaction. Age differences in life satisfaction followed a cubic trajectory: lower during emerging adulthood, higher during midlife, and lower during older adulthood. This study adds to accumulating evidence that daily fluctuations in physical activity have important implications for well-being regardless of age, and clarifies developmental differences in life satisfaction dynamics that can inform strategies for enhancing life satisfaction.

    BACKGROUND: Stroke is the leading cause of death and long-term disability. This study was undertaken to investigate the factors influencing daily activities of patients with cerebral infarction so as to take interventional measures earlier to improve their daily activities. METHODS: A total of 149 patients with first-episode cerebral infarction were recruited into this prospective study. They were admitted to the Encephalopathy Center, Department of Neurology, the First Affiliated Hospital of Wenzhou Medical College in Zhejiang Province from August 2008 to December 2008. The baseline characteristics of the patients and cerebral infarction risk factors on the first day of admission were recorded. White blood cell (WBC) count, plasma glucose (PG), and many others of laboratory targets were collected in the next morning. Barthel index (BI) was calculated at 2 weeks and 3 months respectively after onset of the disease at the outpatient clinic or by telephone call. Lung infection, urinary tract infection and atrial fibrillation if any were recorded on admission. The National Institute of Health Stroke Scale (NIHSS) scores and the GCS scores were recorded within 24 hours on and after admission, at the second week, and at the third month after the onset of cerebral infarction respectively. RESULTS: The factors of BI at 2 weeks and 3 months after onset were the initial PG level, WBC count and initial NIHSS scores. Besides, urinary tract infection on admission was also the factor for BI at 3 months. CONCLUSION: Active measures should be taken to control these factors to improve the daily activities of patients with cerebral infarction. PMID:25214953

    The purpose of this study was to get reliable insight into injury risk in various commuting and lifestyle activities, as well as recreational and competitive sports. A cohort of 3 657 persons was randomly selected from the 15- to 74-year-old Finnish population. Ninety-two percent (n = 3 363) of the subjects accepted to participate the one-year follow-up, record all their physical activities that lasted 15 min or more, and register all acute and overuse injuries that occurred during these activities. To collect the information, the study subjects were interviewed by phone by the trained personnel of the Statistics Finland three times in four-month intervals. The individual injury risk per exposure time was relatively low, ranging from 0.19 to 1.5 per 1 000 hours of participation, in commuting and lifestyle activities including walking and cycling to work, gardening, home repair, hunting and fishing, and, in sports such as golf, dancing, swimming, walking, and rowing. The risk was clearly higher in squash, orienteering, and contact and team sports, such as judo, wrestling, karate, rinkball, floorball, basketball, soccer, ice hockey, volleyball, and Finnish baseball ranging from 6.6 to 18.3 per 1 000 hours of participation. However, the highest absolute number of injuries occurred in low-risk activities, such as gardening, walking, home-repair, and cycling, because they are performed so often. In conclusion, individual injury risk per exposure hours is relatively low in commuting and lifestyle activities compared to many recreational and competitive sports. However, at a population level, these low-to-moderate intensity activities are widely practised producing a rather high absolute number of injuries, and thus, preventive efforts are needed in these activities, too.

    Executive functions (EFs) in childhood predict important life outcomes. Thus, there is great interest in attempts to improve EFs early in life. Many interventions are led by trained adults, including structured training activities in the lab, and less-structured activities implemented in schools. Such programs have yielded gains in children's externally-driven executive functioning, where they are instructed on what goal-directed actions to carry out and when. However, it is less clear how children's experiences relate to their development of self-directed executive functioning, where they must determine on their own what goal-directed actions to carry out and when. We hypothesized that time spent in less-structured activities would give children opportunities to practice self-directed executive functioning, and lead to benefits. To investigate this possibility, we collected information from parents about their 6–7 year-old children's daily, annual, and typical schedules. We categorized children's activities as “structured” or “less-structured” based on categorization schemes from prior studies on child leisure time use. We assessed children's self-directed executive functioning using a well-established verbal fluency task, in which children generate members of a category and can decide on their own when to switch from one subcategory to another. The more time that children spent in less-structured activities, the better their self-directed executive functioning. The opposite was true of structured activities, which predicted poorer self-directed executive functioning. These relationships were robust (holding across increasingly strict classifications of structured and less-structured time) and specific (time use did not predict externally-driven executive functioning). We discuss implications, caveats, and ways in which potential interpretations can be distinguished in future work, to advance an understanding of this fundamental aspect of growing up

  13. Using multiple travel paths to estimate daily travel distance in arboreal, group-living primates.

    PubMed

    Steel, Ruth Irene

    2015-01-01

    Primate field studies often estimate daily travel distance (DTD) in order to estimate energy expenditure and/or test foraging hypotheses. In group-living species, the center of mass (CM) method is traditionally used to measure DTD; a point is marked at the group's perceived center of mass at a set time interval or upon each move, and the distance between consecutive points is measured and summed. However, for groups using multiple travel paths, the CM method potentially creates a central path that is shorter than the individual paths and/or traverses unused areas. These problems may compromise tests of foraging hypotheses, since distance and energy expenditure could be underestimated. To better understand the magnitude of these potential biases, I designed and tested the multiple travel paths (MTP) method, in which DTD was calculated by recording all travel paths taken by the group's members, weighting each path's distance based on its proportional use by the group, and summing the weighted distances. To compare the MTP and CM methods, DTD was calculated using both methods in three groups of Udzungwa red colobus monkeys (Procolobus gordonorum; group size 30-43) for a random sample of 30 days between May 2009 and March 2010. Compared to the CM method, the MTP method provided significantly longer estimates of DTD that were more representative of the actual distance traveled and the areas used by a group. The MTP method is more time-intensive and requires multiple observers compared to the CM method. However, it provides greater accuracy for testing ecological and foraging models.

    Organisms respond to cyclical environmental conditions by entraining their endogenous biological rhythms. Such physiological responses are expected to be substantial for species inhabiting arid environments which incur large variations in daily and seasonal ambient temperature (T(a)). We measured core body temperature (T(b)) daily rhythms of Cape ground squirrels Xerus inauris inhabiting an area of Kalahari grassland for six months from the Austral winter through to the summer. Squirrels inhabited two different areas: an exposed flood plain and a nearby wooded, shady area, and occurred in different social group sizes, defined by the number of individuals that shared a sleeping burrow. Of a suite of environmental variables measured, maximal daily T(a) provided the greatest explanatory power for mean T(b) whereas sunrise had greatest power for T(b) acrophase. There were significant changes in mean T(b) and T(b) acrophase over time with mean T(b) increasing and T(b) acrophase becoming earlier as the season progressed. Squirrels also emerged from their burrows earlier and returned to them later over the measurement period. Greater increases in T(b), sometimes in excess of 5°C, were noted during the first hour post emergence, after which T(b) remained relatively constant. This is consistent with observations that squirrels entered their burrows during the day to 'offload' heat. In addition, greater T(b) amplitude values were noted in individuals inhabiting the flood plain compared with the woodland suggesting that squirrels dealt with increased environmental variability by attempting to reduce their T(a)-T(b) gradient. Finally, there were significant effects of age and group size on T(b) with a lower and less variable T(b) in younger individuals and those from larger group sizes. These data indicate that Cape ground squirrels have a labile T(b) which is sensitive to a number of abiotic and biotic factors and which enables them to be active in a harsh and variable

  16. Daily activity during stability and exacerbation of chronic obstructive pulmonary disease

    PubMed Central

    2014-01-01

    Background During most COPD exacerbations, patients continue to live in the community but there is little information on changes in activity during exacerbations due to the difficulties of obtaining recent, prospective baseline data. Methods Patients recorded on daily diary cards any worsening in respiratory symptoms, peak expiratory flow (PEF) and the number of steps taken per day measured with a Yamax Digi-walker pedometer. Exacerbations were defined by increased respiratory symptoms and the number of exacerbations experienced in the 12 months preceding the recording of daily step count used to divide patients into frequent (> = 2/year) or infrequent exacerbators. Results The 73 COPD patients (88% male) had a mean (±SD) age 71(±8) years and FEV1 53(±16)% predicted. They recorded pedometer data on a median 198 days (IQR 134–353). At exacerbation onset, symptom count rose by 1.9(±1.3) and PEF fell by 7(±13) l/min. Mean daily step count fell from 4154(±2586) steps/day during a preceding baseline week to 3673(±2258) step/day during the initial 7 days of exacerbation (p = 0.045). Patients with larger falls in activity at exacerbation took longer to recover to stable level (rho = −0.56; p < 0.001). Recovery in daily step count was faster (median 3.5 days) than for exacerbation symptoms (median 11 days; p < 0.001). Recovery in step count was also faster in untreated compared to treated exacerbation (p = 0.030). Daily step count fell faster over time in the 40 frequent exacerbators, by 708 steps/year, compared to 338 steps/year in 33 infrequent exacerbators (p = 0.002). Conclusions COPD exacerbations reduced physical activity and frequent exacerbations accelerate decline in activity over time. PMID:24885188

    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.

    We propose a model for the dynamics of a probe embedded in a living cell, where both thermal fluctuations and nonequilibrium activity coexist. The model is based on a confining harmonic potential describing the elastic cytoskeletal matrix, which undergoes random active hops as a result of the nonequilibrium rearrangements within the cell. We describe the probe's statistics and we bring forth quantities affected by the nonequilibrium activity. We find an excellent agreement between the predictions of our model and experimental results for tracers inside living cells. Finally, we exploit our model to arrive at quantitative predictions for the parameters characterizing nonequilibrium activity, such as the typical time scale of the activity and the amplitude of the active fluctuations.

    OBJECTIVE. The objective of this study was to determine whether facility-level, structural factors affect the provision of assistive devices and services. DESIGN. A retrospective design was used. Activities of daily living and mobility-related devices were categorized into 11 types. Logistic regression models were performed for each type of device, controlling for patient-level and facility-level covariates. RESULTS. Non–veteran-level factors significantly affect the provision of assistive devices, even after covariate adjustment. Increased rehabilitation clinician staffing by 1 full-time equivalent position was associated with increased provision odds of 1%–5% for 5 of 11 types of devices. Lower facility complexity was significantly associated with increased provision odds of 35%–59% for 3 types of devices and with decreased provision odds of 16%–69% for 3 types of devices. CONCLUSION. System-level factors, in addition to patient need, significantly affect the provision of assistive devices. Provision guidelines could assist clinicians in making decisions about device provision.

    [Purpose] The purpose of this study was to evaluate the effects of mental practice on stroke patients’ upper extremity function and activities of daily living (ADL). [Subjects and Methods] In this study, 29 stroke patients were randomly assigned to two groups: an experimental group (n=14) and a control group (n=15). The experimental group performed 10 minutes of mental practice once a day, 5 days a week for 2 weeks in combination with conventional rehabilitation therapy. For the control group, general rehabilitation therapy was provided during the same sessions as the experimental group. The Action Research Arm Test (ARAT) and the Fugl-Myer assessment (FMA) were used to measure upper extremity function, and the Modified Bathel Index (MBI) was used to measure daily activity performance. [Results] After the intervention, the mental practice group showed significant improvements in upper extremity function on the affected side and ADL scores compared to the control group. [Conclusion] The results of this study demonstrate mental practice intervention is effective at improving stroke patients’ upper extremity function and daily activity performance. In follow-up studies, securing a greater number of experimental subjects, and evaluation of the intervention’s therapeutic durability are required. PMID:25995560

    Older adults with cognitive impairment often have difficulties in remembering the proper sequence of activities of daily living (ADLs) or how to use the tools necessary to perform ADLs. They, therefore, require reminders in a timely fashion while performing ADLs. This is a very stressful situation for the caregivers of people with dementia. In this paper we describe a pilot study where a tele-operated assistive robot helps a group of older adults with dementia (OAwD) to perform an ADL, namely making a cup of tea in the kitchen. Five OAwD along with their caregivers participated in this study which took place in a simulated-home setting. The purpose of this study was to investigate the feasibility and usability of a robotic system in assisting the OAwD to perform ADL in a home setting. The findings from this study will contribute to achieve our ultimate goal of designing a full-fledged assistive robot that assists OAwD aging in their own homes. The assistive robots designed for people with dementia mostly focus on companionship. This is, to the best of our knowledge, the first attempt to design an assistive robot which will provide step-by-step guidance to people with dementia in their activities of daily living.

    The assessment of real-world functional outcomes in clinical trials for medications targeting negative symptoms and cognitive impairment is extremely important. We tested the psychometric properties of the Daily Activity Report (DAR), a novel assessment of productive daily activity. We administered the DAR and additional assessments of functional outcome, functional capacity, cognition and symptomatology to 50 individuals with schizophrenia at 2 time points, 1 month apart and to 25 healthy controls. The DAR records a person’s daily activity for 7 consecutive days based upon phone calls made 3 times a day. A total score and scores in 3 domains; instrumental activities (ie, independent living), social and work or school related activities are generated for the DAR. Inter-item consistency was high 0.89–0.94 for each domain and 0.88 overall. Test–retest reliability across 1 month for the total DAR score was 0.67, P < .0001. The total DAR score as well as scores for social activity and nondomestic work/school differed significantly between control and patient participants (P < .0001). DAR domain scores were associated with negative symptoms and functional outcomes, but the primary score related to these measures was the work/school dimension of the DAR. DAR scores were only weakly and nonsignificantly related to positive symptoms. This study provides preliminary support for the reliability and validity of the DAR using interviewer administration. The development of a patient reported version of the DAR using smart phone technology with automatic scoring is the next step. PMID:26712856

    Background Total sedentary time varies across population groups with important health consequences. Patterns of sedentary time accumulation may vary and have differential health risks. The purpose of this study is to describe sedentary patterns of older adults living in retirement communities and illustrate gender and age differences in those patterns. Methods Baseline accelerometer data from 307 men and women (mean age = 84±6 years) who wore ActiGraph GT3X+ accelerometers for ≥ 4 days as part of a physical activity intervention were classified into bouts of sedentary time (<100 counts per minute). Linear mixed models were used to account for intra-person and site-level clustering. Daily and hourly summaries were examined in mutually non-exclusive bouts of sedentary time that were 1+, 5+, 10+, 20+, 30+, 40+, 50+, 60+, 90+ and 120+ minutes in duration. Variations by time of day, age and gender were explored. Results Men accumulated more sedentary time than women in 1+, 5+, 10+, 20+, 30+, 40+, 50+ and 60+ minute bouts; the largest gender-differences were observed in 10+ and 20+ minute bouts. Age was positively associated with sedentary time, but only in bouts of 10+, 20+, 30+, and 40+ minutes. Women had more daily 1+ minute sedentary bouts than men (71.8 vs. 65.2), indicating they break up sedentary time more often. For men and women, a greater proportion of time was spent being sedentary during later hours of the day than earlier. Gender differences in intra-day sedentary time were observed during morning hours with women accumulating less sedentary time overall and having more 1+ minute bouts. Conclusions Patterns identified using bouts of sedentary time revealed gender and age differences in the way in which sedentary time was accumulated by older adults in retirement communities. Awareness of these patterns can help interventionists better target sedentary time and may aid in the identification of health risks associated with sedentary behavior. Future studies

    Objective In order to assess the impact of educational content on students, this study investigated junior high school students' awareness of older adults' daily lives and the social resources available for older adults.Methods Participants were 967 second-year students at a public junior high school in S city. A complete enumeration survey was conducted using anonymous self-administered questionnaires. The survey items obtained information about participants' demographic characteristics, their perceptions of older adults' daily life, and their awareness of the social resources for older adults.Results Of the 555 returned questionnaires (57.4%), 490 (50.7%) valid responses were analyzed. A total of 158 participants (32.2%) lived with their grandparents, and 232 participants (47.3%) had some experience living with their grandparents, most of whom still lived independently. Further, 303 participants (61.8%) met their grandparents at least once or twice a week. The mean age of participants' grandparents was 72.2 years. The mean age that the participants regarded a person as "elderly" was 71.3 years. Participants' perceptions of older adults' daily lives included decreased physical ability due to aging, need and desire to stay in touch with family and/or friends, and enjoying hobbies and pleasurable activities. Participants who met their grandparents at least once or twice a week perceived elderly life as more cheerful compared to participants who met their grandparents once or twice a month or less. The participants were familiar with some social resources for older adults such as "administrative disaster-prevention wireless communication system," "transportation service by car," and "visiting nurse." Female participants were aware of significantly more social resources compared to male participants, as were participants who met their grandparents at least once or twice a week compared to those who met their grandparents once or twice a month or less

    Correctly identifying other's emotional states is a central cognitive component of empathy. We examined the role of fluid cognitive performance for empathic accuracy for happiness in the daily lives of 86 older couples (mean relationship length = 45 years; mean age = 75 years) on up to 42 occasions over 7 consecutive days. Men performing better on the Digit Symbol test were more accurate in identifying ups and downs of their partner's happiness. A similar association was not found for women. We discuss the potential role of fluid cognitive performance and other individual, partner, and situation characteristics for empathic accuracy. (PsycINFO Database Record PMID:27362351

    The primary objective of this study was to determine whether the absence of outdoor activities is associated with an increased risk of mortality among elderly people living at home. In January 1995, the authors enrolled 863 household residents, 65 years old and older, who were able to fully understand and complete a baseline interview unassisted. Participant demographics, functional capabilities, activities of daily living, and three dimensions of outdoor activities (initiative, transport, and frequency) were examined. Cohort mortality was assessed through December 1999. Of the 863 participants, 139 (16.1%) died within the study observation period. After adjusting for gender and age, three dimensions of functional impairment (vision, hearing, and speech), impairment in activities of daily living, and all three dimensions of outdoor activities were predictive of 5-year mortality. In multivariate analysis, these three dimensions remained as explanatory variables for mortality at 5 years. Assessment of outdoor-activity levels can help identify elderly individuals with greater mortality risk.

    Alcohol-antiretroviral therapy (ART) interactive toxicity beliefs reflect perceived adverse outcomes of mixing alcohol and ART. Previous research has shown a significant relationship between alcohol-ART interactive toxicity beliefs and ART non-adherence, over and above other correlates of non-adherence such as human immunodeficiency virus (HIV)symptoms and frequency of alcohol use. Most past studies have collected data over extended periods and have not determined if alcohol use and missed medications occur at the day-level among people holding interactive toxicity beliefs. Previous daily analyses, however, have been limited by self-reported adherence and relatively short periods of observation. To address these gaps in the literature, men and women living with HIV in Atlanta, GA, were enrolled in a 45-day observational cohort study. Daily alcohol use was collected using two-way interactive text message surveys and daily adherence was collected via the Wisepill device. Fifty-seven participants completed a measure of alcohol-ART interactive toxicity beliefs and contributed 2565 days of daily data. Participants who endorsed high levels of interactive toxicity beliefs had significantly more days when they missed doses of medication. Alcohol-antiretroviral toxicity beliefs predicted missing doses of medication on days when participants were drinking and on days when they were not drinking. Multilevel multivariate regressions showed that these toxicity beliefs predicted daily missed doses of medication over and above quantity of alcohol consumed, depression and general medication concerns. This study replicates and extends previous literature and indicates the necessity of addressing alcohol-ART toxicity beliefs within adherence interventions.

    Information and communication technologies are widely and rapidly spreading in people's daily lives. But what is the possible role of the mass proliferation of digital devices in supporting healthy living and active ageing? Are they useful in fostering personal growth and individual integration of the elderly, by promoting satisfaction, opportunities for action, and self-expression? Rather, do they enhance automation, impose constraints on personal initiative, and result in compulsive consumption of information? In this chapter, we suggest that possible answers to these questions will be offered by the "Positive Technology" approach, i.e., the scientific and applied approach to using technology so that it improves the quality of our personal experiences through its structuring, augmentation, and/or replacement. First, we suggest that it is possible to use technology to manipulate the quality of experience with the goal of increasing wellness and generating strengths and resilience in individuals, organizations, and society. Then, we classify positive technologies according to their effects on these three features of personal experience - Hedonic: technologies used to induce positive and pleasant experiences; Eudaimonic: technologies used to support individuals in reaching engaging and self-actualizing experiences; Social/Interpersonal: technologies used to support and improve the connectedness between individuals, groups, and organizations. Finally, we discuss the possible role of positive technologies for healthy living and active ageing by presenting different practical applications of this approach.

    In this introduction to the Special Issue on Technology we explore the continued evolution of technologies designed to help individuals with autism. Through review articles, empirical reports, and perspectives, we examine how far the field has come and how much further we still can go. Notably, even as we highlight the continuing need for larger empirical studies of autism-focused technology, we note how improvements in the portability, sophistication, ubiquity, and reach of daily technologies are providing new opportunities for research, education, enhancement, knowledge, and inspiration. We conclude by discussing how the next generation of technologies may leverage the increasing promise of big-data approaches to move us towards a future where technology is more personal, more relevant, and pervasively transformative.

    Accurate identification of physical activity types has been achieved in laboratory conditions using single-site accelerometers and classification algorithms. This methodology is then applied to free-living subjects to determine activity behavior. This study is aimed at analyzing the reproducibility of the accuracy of laboratory-trained classification algorithms in free-living subjects during daily life. A support vector machine (SVM), a feed-forward neural network (NN), and a decision tree (DT) were trained with data collected by a waist-mounted accelerometer during a laboratory trial. The reproducibility of the classification performance was tested on data collected in daily life using a multiple-site accelerometer augmented with an activity diary for 20 healthy subjects (age: 30 ± 9; BMI: 23.0 ± 2.6 kg/m(2)). Leave-one-subject-out cross validation of the training data showed accuracies of 95.1 ± 4.3%, 91.4 ± 6.7%, and 92.2 ± 6.6% for the SVM, NN, and DT, respectively. All algorithms showed a significantly decreased accuracy in daily life as compared to the reference truth represented by the IDEEA and diary classifications (75.6 ± 10.4%, 74.8 ± 9.7%, and 72.2 ± 10.3%; p < 0.05). In conclusion, cross validation of training data overestimates the accuracy of the classification algorithms in daily life.

    What benefit will new technologies offer if they are inadequately or not used? This work presents a meta-synthesis of adoption of technology related findings from four innovative monitoring intervention research studies with older adults and their informal and/or formal caregivers. Each study employed mixed methods analyses that lead to an understanding of the key variables that influenced adoption of telephone and Internet based wireless remote monitoring technologies by elders and their caregivers. The studies were all conducted in “real world” homes ranging from solo residences to multi-story independent living residential buildings. Insights gained came from issues not found in controlled laboratory environments but in the complex interplay of family-elder-staff dynamics around balancing safety and independence. Findings resulted in an adoption of technology model for remote monitoring of elders’ daily activities derived from evidence based research to advance both practical and theoretical development in the field of gerontechnology.

  1. Capturing Intrusive Re-experiencing in Trauma Survivors’ Daily Lives Using Ecological Momentary Assessment

    PubMed Central

    2013-01-01

    Intrusive memories are common following traumatic events and among the hallmark symptoms of posttraumatic stress disorder (PTSD). Most studies assess summarized accounts of intrusions retrospectively. We used an ecological momentary approach and index intrusive memories in trauma survivors with and without PTSD using electronic diaries. Forty-six trauma survivors completed daily diaries for 7 consecutive days recording a total of 294 intrusions. Participants with PTSD experienced only marginally more intrusions than those without PTSD, but experienced them with more “here and now quality,” and responded with more fear, helplessness, anger, and shame than those without PTSD. Most frequent intrusion triggers were stimuli that were perceptually similar to stimuli from the trauma. Individuals with PTSD experienced diary-prompted voluntary trauma memories with the same sense of nowness and vividness as involuntary intrusive trauma memories. The findings contribute to a better understanding of everyday experiences of intrusive reexperiencing in trauma survivors with PTSD and offer clinical treatment implications. PMID:24364602

    Concerns about animal welfare increasingly shape people's views about the acceptability of keeping animals for food production, biomedical research, and in zoos. The field of animal welfare science has developed over the past 50 years as a method of investigating these concerns via research that assesses how living in human-controlled environments influences the behavior, health and affective states of animals. Initially, animal welfare research focused on animals in agricultural settings, but the field has expanded to zoos because good animal welfare is essential to zoos' mission of promoting connections between animals and visitors and raising awareness of conservation issues. A particular challenge for zoos is ensuring good animal welfare for long-lived, highly social species like elephants. Our main goal in conducting an epidemiological study of African (Loxodonta africana) and Asian (Elephas maximus) elephant welfare in 68 accredited North American zoos was to understand the prevalence of welfare indicators in the population and determine the aspects of an elephant's zoo environment, social life and management that are most important to prevent and reduce a variety of welfare problems. In this overview, we provide a summary of the findings of the nine papers in the collection titled: Epidemiological Investigations of North American Zoo Elephant Welfare with a focus on the life history, social, housing, and management factors found to be associated with particular aspects of elephant welfare, including the performance of abnormal behavior, foot and joint problems, recumbence, walking rates, and reproductive health issues. Social and management factors were found to be important for multiple indicators of welfare, while exhibit space was found to be less influential than expected.

    In marmosets, a phase advance was observed in activity onset in pubertal animals living in captivity under semi-natural conditions which had stronger correlation with the times of sunrise over the course of the year than the age of the animal. In order to evaluate the effect of puberty on the circadian activity rhythm in male and female marmosets living in family groups in controlled lighting conditions, the activity of 5 dyads of twins (4 ♀/♂ and 1 ♂/♂) and their respective parents was continuously monitored by actiwatches between the 4th and 12th months of age. The families were kept under LD 12:12 h with constant humidity and temperature. The onset of puberty was identified by monitoring fecal steroids. Juveniles showed higher totals of daily activity and differences in the daily distribution of activity in relation to parents, in which the bimodal profile was characterized by higher levels in evening activity in relation to morning activity. Regarding the phase, the activity onset and offset, occurred later in relation to parents. After entering puberty, the activity onset and offset occurred later and there was an increase in total daily activity. On the other hand, when assessing the effect of sex, only females showed a delay in the activity offset and an increase in total daily activity. Therefore, the circadian activity rhythm in marmosets has peculiar characteristics in the juvenile stage in relation to the total of daily activity, the onset and offset of the active phase, and the distribution of activity during this phase. Besides, the entering puberty was associated with a phase delay and increase on total daily activity, with differences between sexes, possibly due to hormonal influences and/or social modulation on rhythm.

    The occurrence of edge loading in hip joint replacement has been associated with many factors such as prosthetic design, component malposition and activities of daily living. The present study aimed to quantify the occurrence of edge loading/contact at the articulating surface and to evaluate the effect of cup angles and edge loading on the contact mechanics of a modular metal-on-polyethylene (MoP) total hip replacement (THR) during different daily activities. A three-dimensional finite element model was developed based on a modular MoP bearing system. Different cup inclination and anteversion angles were modelled and six daily activities were considered. The results showed that edge loading was predicted during normal walking, ascending and descending stairs activities under steep cup inclination conditions (≥55°) while no edge loading was observed during standing up, sitting down and knee bending activities. The duration of edge loading increased with increased cup inclination angles and was affected by the cup anteversion angles. Edge loading caused elevated contact pressure at the articulating surface and substantially increased equivalent plastic strain of the polyethylene liner. The present study suggested that correct positioning the component to avoid edge loading that may occur during daily activities is important for MoP THR in clinical practice.

    This article presents conclusions of research conducted at Ensp/Fiocruz, as part of a master's degree course. One of the objectives of the research to investigate the eating habits of women living in the Rocinha Shantytown (Rio de Janeiro, RJ, Brazil) from a socio-anthropological perspective. The results revealed that the eating habits of the group were repetitive, with few variations in the menu consisting basically of rice, bean, sugars and fats. We further observed the rejection of industrialized and canned products. This food consumption pattern seems to conform to Brazilian food culture revealing the preservation of the national identity based on feeding habits. Consequently, it is necessary to set aside presuppositions regarding the relationship between food consumption and obesity, especially with respect to the predominant idea of changes in diet with the incorporation of a "modern" or "western" diet that prevail in studies in the field of nutrition in Brazil. In this sense, we signaled the need to reassert a multidimensional approach for studies about food and nutrition in the country. This proposal involves overcoming restricted conceptual outlooks and the creation of new avenues of investigation.

    We show, using a large new data set, that the temporally resolved speed of active cargo transport in living cells follows a scaling law over several decades of time and length. The statistical regularities display a time-averaged shape that we interpret to reflect stress buildup, followed by rapid release. The scaling power law agrees quantitatively with those reported in inanimate systems (jammed colloids and granular media, and magnetic Barkhausen noise), suggesting a common origin in pushing through a crowded environment in a weak force regime. The implied regulation of the speed of active cellular transport due to environmental obstruction results in bursts of speed and acceleration. These findings extend the classical notion of molecular crowding.

    Atmospheric concentrations of radon (222Rn) gas and its short-lived progenies 218Po, 214Pb, and 214Po were continuously monitored every four hours at the ground level in Jeddah city, Kingdom of Saudi Arabia. The measurements were performed three times every week, starting from November 2014 to October 2015. A method of electrostatic precipitation of positively charged 218Po and 214Po by a positive voltage was applied for determining 222Rn gas concentration. The short-lived 222Rn progeny concentration was determined by using a filter holder connected with the alpha-spectrometric technique. The meteorological parameters (relative air humidity, air temperature, and wind speed) were determined during the measurements of 222Rn and its progeny concentrations. 222Rn gas as well as its short-lived progeny concentration display a daily and seasonal variation with high values in the night and early morning hours as compared to low values at noon and in the afternoon. The observed monthly atmospheric concentrations showed a seasonal trend with the highest values in the autumn/winter season and the lowest values in the spring/summer season. Moreover, and in parallel with alpha-spectrometric measurements, a single filter-holder was used to collect air samples. The deposited activities of 214Pb and the long-lived 222Rn daughter 210Pb on the filter were measured with the gamma spectrometric technique. The measured activity concentrations of 214Pb by both techniques were found to be relatively equal largely. The highest mean seasonally activity concentrations of 210Pb were observed in the autumn/winter season while the lowest mean were observed in the spring/summer season. The mean residence time (MRT) of aerosol particles in the atmospheric air could be estimated from the activity ratios of 210Pb/214Pb.

    The purpose of this study was to examine the extent of lower extremity impairments in motion and strength in people with systemic sclerosis and the relationships of the impairments to limitations in activities of daily living primarily involving the lower extremities. Participants were 69 persons with SSc who received evaluations of lower extremity joint motion (Keitel function test), strength (timed-stands test), and basic mobility (timed up and go test) and completed a demographic questionnaire regarding symptoms in the lower extremities. Activity limitations were measured by the Rheumatoid and Arthritis Outcome Score (RAOS) which examines functional ability, pain, and quality of life. The participants had difficulty with items requiring external rotation of the hips and lower extremity strength. There were moderate correlations between the impairment measures of joint motion, strength, mobility, and activity limitations. Fair correlations were found between the skin scores and the RAOS sections except for pain. The results of this study show that lower extremity involvement is present in persons with SSc. The findings, regarding strength, mobility, and joint motion are related to the ability to perform everyday activities involving the lower extremities, suggest that these areas should be targeted for intervention in persons with SSc.

    Studies of place and health often classify a subject's exposure status according to that which is present in their neighborhood of residence. One's neighborhood is often proxied by designating it to be an administratively defined unit such as census tract, to make analysis feasible. Although it is understood that residential space and actual lived space may not correspond and therefore exposure misclassification may result, few studies have the opportunity to investigate the implications of this issue concretely. A population-based case-control study that is currently underway provides one such opportunity. Adolescent victims of assault in Philadelphia, Pennsylvania, USA, and a control sample of adolescents drawn randomly from the community are being enrolled to study how alcohol consumption and time spent nearby alcohol outlets - individual-level and environmental-level risk factors for violence, respectively - over the course of daily activities relate to the likelihood of being assaulted. Data from a rapport-building exercise consist of hand-drawn sketches that subjects drew on street maps when asked to indicate the area considered their neighborhood. The main data consist of self-reported, detailed paths of the routes adolescents traveled from one location to the next over the course of one full day. Having noticed interesting patterns as the data collection phase proceeds, we present here an analysis conducted with the data of 55 control subjects between 15 and 19 years old. We found that hand-drawn neighborhoods and activity paths did not correspond to census tract boundaries, and time subjects spent in close proximity to alcohol outlets during their daily activities was not correlated with the prevalence of alcohol outlets in the census tract of their residence. This served as a useful example demonstrating how classifying subjects as exposed based solely on the prevalence of the exposure in the geographic area of their residence may misrepresent the

  14. Living science: Science as an activity of living beings.

    MacLennan, Bruce J

    2015-12-01

    The philosophy of science should accommodate itself to the facts of human existence, using all aspects of human experience to adapt more effectively, as individuals, species, and global ecosystem. This has several implications: (1) Our nature as sentient beings interacting with other sentient beings requires the use of phenomenological methods to investigate consciousness. (2) Our embodied, situated, purposeful physical interactions with the world are the foundation of scientific understanding. (3) Aristotle's four causes are essential for understanding living systems and, in particular, the final cause aids understanding the role of humankind, and especially science, in the global ecosystem. (4) In order to fulfill this role well, scientists need to employ the full panoply of human faculties. These include the consciousness faculties (thinking, sensation, feeling, intuition), and therefore, as advocated by many famous scientists, we should cultivate our aesthetic sense, emotions, imagination, and intuition. Our unconscious faculties include archetypal structures common to all humans, which can guide scientific discovery. By striving to engage the whole of human nature, science will fulfill better its function for humans and the global ecosystem.

    We conducted a meta-synthesis of five different studies that developed, tested, and implemented new technologies for the purpose of collecting Observations of Daily Living (ODL). From this synthesis, we developed a model to explain user motivation as it relates to ODL collection. We describe this model that includes six factors that motivate patients’ collection of ODL data: usability, illness experience, relevance of ODLs, information technology infrastructure, degree of burden, and emotional activation. We show how these factors can act as barriers or facilitators to the collection of ODL data and how interacting with care professionals and sharing ODL data may also influence ODL collection, health-related awareness, and behavior change. The model we developed and used to explain ODL collection can be helpful to researchers and designers who study and develop new, personal health technologies to empower people to improve their health.

    1992-11-01

    A survey was undertaken in Cincinnati to obtain information on the activity patterns of asthmatics. Because studies have demonstrated symptomatic responses to elevated levels of SO[sub 2] only during outdoor exercise, information on the behavioral patterns of asthmatics is vital for the accurate estimation of risk due to air pollution exposures. In particular, data detailing the actual likelihood of asthmatics being engaged in strenuous outdoor activity at any given time of day is essential for an accurate appraisal of response probability. This, in turn, is necessary for an accurate estimate of risk. In the absence of such activity data, those concerned with the setting of short-term SO[sub 2] regulations are required to use purely subjective judgment to estimate how many asthmatics are engaged in strenuous outdoor exercise when SO[sub 2] levels are high enough to affect them. The activity pattern data give an indication of how much such an assumption would overestimate the true response and thus the true risk associated with SO[sub 2]. Lack of information on the activity patterns of asthmatics has thus been a critical gap in the SO[sub 2] risk assessment process. The primary purpose of this survey was to fill that gap.

    NASA Astrophysics Data System (ADS)

    Mijling, B.; van der A, R. J.

    2012-09-01

    Emission inventories of air pollutants are crucial information for policy makers and form important input data for air quality models. Using satellite observations for emission estimates has important advantages over bottom-up emission inventories: they are spatially consistent, have high temporal resolution, and enable updates shortly after the satellite data become available. We present a new algorithm specifically designed to use daily satellite observations of column concentrations for fast updates of emission estimates of short-lived atmospheric constituents on a mesoscopic scale (˜25 × 25 km2). The algorithm needs only one forward model run from a chemical transport model to calculate the sensitivity of concentration to emission, using trajectory analysis to account for transport away from the source. By using a Kalman filter in the inverse step, optimal use of the a priori knowledge and the newly observed data is made. We apply the algorithm for NOx emission estimates of East China, using the CHIMERE model on a 0.25 degree resolution together with tropospheric NO2column retrievals of the OMI and GOME-2 satellite instruments. Closed loop tests show that the algorithm is capable of reproducing new emission scenarios. Applied with real satellite data, the algorithm is able to detect emerging sources (e.g., new power plants), and improves emission information for areas where proxy data are not or badly known (e.g., shipping emissions). Chemical transport model runs with the daily updated emission estimates provide better spatial and temporal agreement between observed and simulated concentrations, facilitating improved air quality forecasts.

    Body movement is responsible for most of the interference during physiological data acquisition during normal daily activities. In this paper, we introduce nonwoven fabric active electrodes that provide the comfort required for clothing while robustly recording physiological data in the presence of body movement. The nonwoven fabric active electrodes were designed and fabricated using both hand- and screen-printing thick-film techniques. Nonstretchable nonwoven (Evolon 100) was chosen as the flexible fabric substrate and a silver filled polymer ink (Creative Materials CMI 112-15) was used to form a transducer layer and conductive lines on the nonwoven fabrics. These nonwoven fabric active electrodes can be easily integrated into clothing for wearable health monitoring applications. Test results indicate that nonwoven textile-based sensors show considerable promise for physiological data acquisition in wearable healthcare monitoring applications.

    2013-01-01

    Background Cerebral Palsy (CP) presents changes in posture and movement as a core characteristic, which requires multiprofessional clinical treatments during children’s habilitation or rehabilitation. Besides clinical treatment, it is fundamental that professionals use evaluation systems to quantify the difficulties presented to the individual and their families in their daily lives. We aimed to investigate the functional capacity of individuals with CP and the amount of assistance required by the caregiver in day-to-day activities. Methods Twenty patients with CP, six-year-old on average, were evaluated. The Pediatric Evaluation Inventory of Incapacities was used (PEDI - Pediatric Evaluation Disability Inventory), a system adapted for Brazil that evaluates child's dysfunction in three 3 dimensions: self-care, mobility and social function. To compare the three areas, repeated measures analysis of variance (ANOVA) were used. Results We found the following results regarding the functional capacity of children: self-care, 27.4%, ±17.5; mobility, 25.8%, ±33.3 and social function, 36.3%, ±27.7. The results of the demand of aid from the caregiver according to each dimension were: self-care, 9.7%, ±19.9; mobility, 14.1%, ± 20.9 and social function, 19.8%, ±26.1. Conclusion We indicated that there was no difference between the performance of the subjects in areas of self-care, mobility and social function considering the functional skills and assistance required by the caregiver.

    Underserved minority communities have few resources for addressing comorbidity risk reduction among long-term cancer survivors. To address this community need, we developed and piloted the Bronx Oncology Living Daily (BOLD) Healthy Living program, the first known diabetes prevention and control program to target cancer survivors and co-survivors in Bronx County, NY. The program aimed to facilitate lifestyle change and improve health-related quality of life (HRQoL) through weekly group nutrition education (60-90 min) and exercise (60 min) classes. We examined baseline characteristics of participants using simple descriptive statistics and evaluated program implementation and impact using the Reach, Efficacy, Adoption, Implementation and Maintenance (RE-AIM) framework. The curriculum, which drew from the social-ecological framework and motivational and cognitive behavioral strategies, consisted of 12 culturally and medically tailored modules with options for implementation as a 12- or 4-week program. Seven programs (four 12 weeks and three 4 weeks in length, respectively) were implemented at five community site locations. Sixty-six cancer survivors and 17 cancer co-survivors (mean age 60.5 ± 10.2 years) enrolled in one of the programs. Most participants were female (95.2 %) minority (55.4 % black, 26.5 % Hispanic/Latino) breast cancer survivors (75.7 %). Median program attendance was 62.5 % and did not significantly differ by program length; however, 67.3 % of participants achieved ≥60 % attendance among the 12-week programs, compared to 41.9 % among the 4-week programs, and this difference was statistically significant (p = 0.02). Overall, participants reported significant pre/post improvements in perceived health as good/excellent (66.0 to 75.5 %; p = 0.001) and borderline significant decreases in perceived pain as moderate/severe (45.5 to 38.2 %; p = 0.05). More than 90 % of participants reported that the program helped them to achieve their

    Emotional disclosure is an expressive writing technique used in psychotherapy to process traumatic and stressful life experiences. While emotional disclosure interventions frequently use control groups, there are few qualitative analyses of these control groups. Our study's purpose was to analyze the control essays written by HIV-infected informants about their daily activities in an augmented written emotional disclosure intervention. Latent and manifest qualitative content analyses revealed prevalent contextual themes within the data. The emergent themes were socioeconomic status (SES), self-care, religiosity/spirituality, and social support. Emotional disclosure control subjects contributed substantial findings in terms of SES, self-care, resiliency, religiosity/spirituality, and social support and altruism. PMID:27426408

    Examined glycemic associations with medical variables, activity, daily stress, and mood state in 72 older patients with non-insulin-dependent diabetes mellitus (NIDDM). On three occasions over a 2-week observation period, subjects provided measures of everyday life stress, negative mood state, and daily activities. At the end of this period, fructosamine was assayed to measure glycemic control throughout the assessment period. After controlling for medical variables (age, illness duration, body mass index, caloric intake, and activity) and the main effects of psychological factors (stress; anxious, angry, and depressed mood states), stress interacted with activity such that glycemic elevation was positively associated with stress for subjects below the activity median but not for those above the median. This was unattributable to any overall activity-related differences in fructosamine, stress, or mood. None of the mood states interacted with activity. The findings suggest that extremely low levels of activity may strengthen life stress-glycemia associations in NIDDM. PMID:9298436

    Hippocampal atrophy is associated with memory impairment and dementia and serves as a key biomarker in the preclinical stages of Alzheimer's disease. Physical activity, one of the most promising behavioral interventions to prevent or delay cognitive decline, has been shown to be associated with hippocampal volume; specifically increased aerobic activity and fitness may have a positive effect on the size of the hippocampus. The majority of older adults, however, are sedentary and have difficulty initiating and maintaining exercise programs. A modestly more active lifestyle may nonetheless be beneficial. This study explored whether greater objectively measured daily walking activity was associated with larger hippocampal volume. We additionally explored whether greater low-intensity walking activity, which may be related to leisure-time physical, functional, and social activities, was associated with larger hippocampal volume independent of exercise and higher-intensity walking activity. Segmentation of hippocampal volumes was performed using Functional Magnetic Resonance Imaging of the Brain's Software Library (FSL), and daily walking activity was assessed using a step activity monitor on 92, nondemented, older adult participants. After controlling for age, education, body mass index, cardiovascular disease risk factors, and the Mini Mental State Exam, we found that a greater amount, duration, and frequency of total daily walking activity were each associated with larger hippocampal volume among older women, but not among men. These relationships were specific to hippocampal volume, compared with the thalamus, used as a control brain region, and remained significant for low-intensity walking activity, independent of moderate- to vigorous-intensity activity and self-reported exercise. This is the first study, to our knowledge, to explore the relationship between objectively measured daily walking activity and hippocampal volume in an older adult population. Findings

    Estrogenic signaling shapes and modifies daily and circadian rhythms, the disruption of which has been implicated in psychiatric, neurologic, cardiovascular, and metabolic disease, among others. However, the activational mechanisms contributing to these effects remain poorly characterized. To determine the activational impact of estrogen on daily behavior patterns and differentiate between the contributions of the estrogen receptors ESR1 and ESR2, ovariectomized adult female mice were administered estradiol, the ESR1 agonist propylpyrazole triol, the ESR2 agonist diarylpropionitrile, or cholesterol (control). Animals were singly housed with running wheels in a 12-hour light, 12-hour dark cycle or total darkness. Estradiol increased total activity and amplitude, consolidated activity to the dark phase, delayed the time of peak activity (acrophase of wheel running), advanced the time of activity onset, and shortened the free running period (τ), but did not alter the duration of activity (α). Importantly, activation of ESR1 or ESR2 differentially impacted daily and circadian rhythms. ESR1 stimulation increased total wheel running and amplitude and reduced the proportion of activity in the light vs the dark. Conversely, ESR2 activation modified the distribution of activity across the day, delayed acrophase of wheel running, and advanced the time of activity onset. Interestingly, τ was shortened by estradiol or either estrogen receptor agonist. Finally, estradiol-treated animals administered a light pulse in the early subjective night, but no other time, had an attenuated response compared with controls. This decreased phase response was mirrored by animals treated with diarylpropionitrile, but not propylpyrazole triol. To conclude, estradiol has strong activational effects on the temporal patterning and expression of daily and circadian behavior, and these effects are due to distinct mechanisms elicited by ESR1 and ESR2 activation.

    As an essential branch of context awareness, activity awareness, especially daily activity monitoring and fall detection, is important to healthcare for the elderly and patients with chronic diseases. In this paper, a framework for activity awareness using surface electromyography and accelerometer (ACC) signals is proposed. First, histogram negative entropy was employed to determine the start- and end-points of static and dynamic active segments. Then, the angle of each ACC axis was calculated to indicate body postures, which assisted with sorting dynamic activities into two categories: dynamic gait activities and dynamic transition ones, by judging whether the pre- and post-postures are both standing. Next, the dynamic gait activities were identified by the double-stream hidden Markov models. Besides, the dynamic transition activities were distinguished into normal transition activities and falls by resultant ACC amplitude. Finally, a continuous daily activity monitoring and fall detection scheme was performed with the recognition accuracy over 98%, demonstrating the excellent fall detection performance and the great feasibility of the proposed method in daily activities awareness.

    Daily ambulatory activity is associated with health and functional status in older adults; however, assessment requires multiple days of activity monitoring. The objective of this study was to determine the relative capabilities of self-selected walking speed (SSWS), maximal walking speed (MWS), and walking speed reserve (WSR) to provide insight into daily ambulatory activity (steps per day) in community-dwelling older adults. Sixty-seven older adults completed testing and activity monitoring (age 80.39 [6.73] years). SSWS (R2 = .51), MWS (R2 = .35), and WSR calculated as a ratio (R2 = .06) were significant predictors of daily ambulatory activity in unadjusted linear regression. Cutpoints for participants achieving < 8,000 steps/day were identified for SSWS (≤ 0.97 m/s, 44.2% sensitivity, 95.7% specificity, 10.28 +LR, 0.58 -LR) and MWS (≤ 1.39 m/s, 60.5% sensitivity, 78.3% specificity, 2.79 +LR, 0.50 -LR). SSWS may be a feasible proxy for assessing and monitoring daily ambulatory activity in older adults. PMID:26371593

    One year has passed since the Great East Japan Earthquake and the Fukushima No. 1 nuclear power plant accident. Even currently, more than 150,000 evacuees in Fukushima Prefecture are forced to leave their home and to move throughout Japan. Because of the limited space of temporary housing and the weakening of personal ties in local communities, many families need to move and have separate lives. As a consequence, Fukushima has a serious shortage of caregivers for the elderly. There have been more than 1,300 disaster-related deaths due to shock and stress after long-distance drifts from town to town. Most of the victims were the elderly, who collapsed, caught pneumonia, suffered stroke and heart attack. Concerns about the safety of low-dose radiation exposure deprived the elderly of important contact with playing outside with their grandchildren in Fukushima. Fear of invisible radioactive contamination inactivated outdoor activities such as farming, dairy, fishing, gardening, hiking and wild-vegetable/mushroom hunting, although most of these activities have been traditionally supported by the wisdom of the elderly. Several recent questionnaire investigations revealed that older evacuees wish to go home even if the environment has significant contamination. In contrast, more than half of younger generation with small children have a different attitude. Nuclear accident brought serious social pains although it did not acutely hurt our bodies.

    Radon activity concentration in the soil air in the area of Faculty of Mathematics, Physics and Informatics (FMPI) in Bratislava, Slovak Republic, has been continuously monitored since 1994. Long-term measurements at a depth of 0.8 m and short-term measurements at a depth of 0.4 m show a high variability in radon activity concentrations in the soil. The analysis of the data confirms that regular daily changes in radon activity concentration in the soil air depend on the daily changes in atmospheric pressure. It was also found that the typical annual courses of the radon activity concentration in the soil air (with summer minima and winter maxima) were disturbed by mild winter and heavy summer precipitation. Influence of precipitation on the increase in the radon activity concentration in the soil air was observed at a depth of 0.4 m and subsequently at a depth of 0.8 m.

    To determine the factors in daily physical activity that influence the mineral density of the calcaneus, we recorded walking steps and the type and duration of exercise in 43 healthy 26-to 51-yr-old men. Areal (g/sq cm) calcaneal bone mineral density (CBMD) was measured by single energy x-ray densitometry. Subjects walked a mean (+/- SD) of 7902(+/-2534) steps per day or approximately 3.9(+/-1.2) miles daily. Eight subjects reported no exercise activities. The remaining 35 subjects spent 143(2-772) (median and range) min/wk exercising. Twenty-eight men engaged in exercise activities that generate single leg peak vertical ground reaction forces (GRF(sub z)) of 2 or more body weights (high loaders, HL), and 15 reported exercise or daily activities that typically generate GRF(sub z) less than 1.5 body weights (low loaders, LL). CBMD was 12% higher in HL than LL (0.668 +/- 0.074 g/sq cm vs 0.597 +/- 0.062 g/sq cm, P less than 0.004). In the HL group, CBMD correlated to reported minutes of high load exercise (r = 0.41, P less than 0.03). CBMD was not related to the number of daily walking steps (N = 43, r = 0.03, NS). The results of this study support the concept that the dominant factor in daily physical activity relating to bone mineral density is the participation in site specific high loading activities, i.e., for the calcaneus, high calcaneal loads.

    This clinical study was performed to investigate hand problems in individuals with systemic lupus erythematosus (SLE) in comparison with healthy controls, and to explore problems in the performance of daily activities related to these hand problems, in order to objectify findings from a previous mail survey. We also investigated whether a simple hand test could detect hand problems in SLE. All individuals, 71 with SLE and 71 healthy controls, were examined for manifestations in body structures and body functions of the hands with a study-specific protocol. The simple hand test was performed by all the individuals and the arthritis impact measurement scale (AIMS 2) questionnaire was completed by the SLE individuals. In the SLE group, 58% had some kind of difficulty in the simple hand test, compared with 8% in the control group. Fifty percent of the SLE individuals experienced problems in performing daily activities due to hand deficits. Pain in the hands, reduced strength and dexterity, Raynaud's phenomenon and trigger finger were the most prominent body functions affecting the performance of daily activities. Deficits in hand function are common in SLE and affect the performance of daily activities. The simple hand test may be a useful tool in detecting hand problems.

    Heterothermy, a variability in body temperature beyond the limits of homeothermy, has been advanced as a key adaptation of Arabian oryx (Oryx leucoryx) to their arid-zone life. We measured body temperature using implanted data loggers, for a 1-year period, in five oryx free-living in the deserts of Saudi Arabia. As predicted for adaptive heterothermy, during hot months compared to cooler months, not only were maximum daily body temperatures higher (41.1 ± 0.3 vs. 39.7 ± 0.1°C, P = 0.0002) but minimum daily body temperatures also were lower (36.1 ± 0.3 vs. 36.8 ± 0.2°C, P = 0.04), resulting in a larger daily amplitude of the body temperature rhythm (5.0 ± 0.5 vs. 2.9 ± 0.2°C, P = 0.0007), while mean daily body temperature rose by only 0.4°C. The maximum daily amplitude of the body temperature rhythm reached 7.7°C for two of our oryx during the hot-dry period, the largest amplitude ever recorded for a large mammal. Body temperature variability was influenced not only by ambient temperature but also water availability, with oryx displaying larger daily amplitudes of the body temperature rhythm during warm-dry months compared to warm-wet months (3.6 ± 0.6 vs. 2.3 ± 0.3°C, P = 0.005), even though ambient temperatures were the same. Free-living Arabian oryx therefore employ heterothermy greater than that recorded in any other large mammal, but water limitation, rather than high ambient temperature, seems to be the primary driver of this heterothermy.

    Selective manipulation of protein kinases under living conditions is highly desirable yet extremely challenging, particularly in a gain-of-function fashion. Here we employ our recently developed bioorthogonal cleavage reaction as a general strategy for intracellular activation of individual kinases. Site-specific incorporation of trans-cyclooctene-caged lysine in place of the conserved catalytic lysine, in conjunction with the cleavage partner dimethyl-tetrazine, allowed efficient lysine decaging with the kinase activity chemically rescued in living systems.

    Observational evidence which supports the contention that Venus is a volcanically and tectonically active planet is discussed. It is argued that, although there are no observations to date that would prove that Venus has been volcanically active during the last decade, planetological studies presented evidence for youthful volcanic mountains on Venus: the surface of the northern quarter of Venus is considered to be younger than 1 Gy, and some units are likely to be much younger. Because of the small sizes of likely volcanic manifestations and the long intervals expected between eruptions, it is unlikely that any direct evidence of eruptions will be detected with existing and planned spacecraft. It is suggested that future studies of the dynamics and the chemical mixing of the Venusian atmosphere might supply an unequivocal evidence for active volcanism on this planet.

    Four studies assessed the effectiveness of verbal instructions presented via technology in helping persons with mild or moderate Alzheimer's disease perform daily activities. The first 2 studies were replication efforts concerning morning bathroom routine and table setting and included 4 and 2 participants, respectively. The third study targeted coffee preparation with 3 participants. The fourth study assessed maintenance and generalization of morning bathroom routine and dressing with 1 participant. Nonconcurrent multiple baseline designs served for the first 3 studies and a 5-month postintervention data collection for the fourth study. Verbal instructions for the activity steps presented via technology were effective in helping the participants of the first 3 studies reacquire basic daily activities and the participant of the fourth study retain the reacquired activities across time and settings. These results suggest that the approach reported may be a useful strategy for helping persons with Alzheimer's disease. PMID:19106276

    Several interventions aiming to enhance physical activity in everyday life showed mixed effects. Affective constructs are thought to potentially support health behavior change. However, little is known about within-subject associations between momentary affect and subsequent physical activity in everyday life. This study analyzed the extent to which three dimensions of affective states (valence, calmness, and energetic arousal) were associated with different components of daily activity trajectories. Sixty-five undergraduates’ students (Age: M = 24.6; SD = 3.2; females: 57%) participated in this study. Physical activity was assessed objectively through accelerometers during 24 h. Affective states assessments were conducted randomly every 45 min using an e-diary with a six-item mood scale that was especially designed for ambulatory assessment. We conducted three-level multi-level analyses to investigate the extent to which momentary affect accounted for momentary volume, prospective trends, and stability vs. fluctuation of physical activity in everyday life. All three affect dimensions were significantly associated with momentary activity volumes and prospective trends over 45 min periods. Physical activity didn’t fluctuate freely, but featured significant autocorrelation across repeated measurements, suggesting some stability of physical activity across 5-min assessments. After adjusting for the autoregressive structure in physical activity assessments, only energetic arousal remained a significant predictor. Feeling energized and awake was associated with an increased momentary volume of activity and initially smaller but gradually growing decreases in subsequent activity within the subsequent 45 min. Although not related to trends in physical activity, higher valence predicted lower stability in physical activity across subsequent 45 min, suggesting more short-term fluctuations in daily activity the more participants reported positive affective valence.

    A device to record and analyze habitual daily activity in terms of the history of gait-related musculoskeletal loading is disclosed. The device consists of a pressure-sensing insole placed into the shoe or embedded in a shoe sole, which detects contact of the foot with the ground. The sensor is coupled to a portable battery-powered digital data logger clipped to the shoe or worn around the ankle or waist. During the course of normal daily activity, the system maintains a record of time-of-occurrence of all non-spurious foot-down and lift-off events. Off line, these data are filtered and converted to a history of foot-ground contact times, from which measures of cumulative musculoskeletal loading, average walking- and running-specific gait speed, total time spent walking and running, total number of walking steps and running steps, and total gait-related energy expenditure are estimated from empirical regressions of various gait parameters to the contact time reciprocal. Data are available as cumulative values or as daily averages by menu selection. The data provided by this device are useful for assessment of musculoskeletal and cardiovascular health and risk factors associated with habitual patterns of daily activity.

    With regard to hearing perception, it remains unclear as to whether, or the extent to which, different conceptual categories of real-world sounds and related categorical knowledge are differentially represented in the brain. Semantic knowledge representations are reported to include the major divisions of living versus non-living things, plus more specific categories including animals, tools, biological motion, faces, and places—categories typically defined by their characteristic visual features. Here, we used functional magnetic resonance imaging (fMRI) to identify brain regions showing preferential activity to four categories of action sounds, which included non-vocal human and animal actions (living), plus mechanical and environmental sound-producing actions (non-living). The results showed a striking antero-posterior division in cortical representations for sounds produced by living versus non-living sources. Additionally, there were several significant differences by category, depending on whether the task was category-specific (e.g. human or not) versus non-specific (detect end-of-sound). In general, (1) human-produced sounds yielded robust activation in the bilateral posterior superior temporal sulci independent of task. Task demands modulated activation of left-lateralized fronto-parietal regions, bilateral insular cortices, and subcortical regions previously implicated in observation-execution matching, consistent with “embodied” and mirror-neuron network representations subserving recognition. (2) Animal action sounds preferentially activated the bilateral posterior insulae. (3) Mechanical sounds activated the anterior superior temporal gyri and parahippocampal cortices. (4) Environmental sounds preferentially activated dorsal occipital and medial parietal cortices. Overall, this multi-level dissociation of networks for preferentially representing distinct sound-source categories provides novel support for grounded cognition models that may

    Objectives This study evaluated the role of both physical activity and sedentary behavior in daily perceptions of cognitive abilities and whether these relations exist within-person, between-person, or both. Design Non-experimental, intensive longitudinal research using ecological momentary assessments. Method College students wore accelerometers and provided end-of-day reports on physical activity, sedentary behavior, and perceived cognitive abilities for 14 days. Results Across self-reports and objective measures of behavior, daily deviations in physical activity were positively associated with perceived cognitive abilities. Daily deviations in self-reported, but not objectively-assessed, sedentary behavior also were negatively associated with perceived cognitive abilities. Contrary to previous research, overall levels of physical activity and sedentary behaviors were not associated with perceived cognitive abilities. Conclusions These findings indicate that physical activity has a within- rather than between-person association with perceived cognitive abilities although between-person associations effects may require longer monitoring periods to manifest. Further research is needed to establish the direction of causality and resolve whether the nature (rather than quantity) of sedentary activities influences cognition. PMID:25419176

    OBJECTIVES There is a shortage of information on metabolic costs of daily physical activities in older adults and the effect of having mobility impairments. The primary purpose of this study was to evaluate metabolic equivalent (MET) values on common daily tasks in men and women aged > 70 years compared to normative criteria. A secondary purpose was to determine the effect of having mobility impairments. DESIGN Cross-sectional observational study. SETTING University based research clinic PARTICIPANTS Forty-five participants aged 70 to 90 years of age (mean: 76.3 ± 5.1) volunteered to complete 17 daily activities, each lasting 10 minutes. MEASUREMENTS Oxygen consumption (VO2 = ml•kg−1•min−1) was measured through a mask by a portable gas analyzer and MET values were calculated as measured VO2/3.5 ml•kg−1•min−1. Values were compared to both normative values and between participants with and without mobility impairments. RESULTS Compared to the established normative criteria, measured METs were different in 14 of 17 tasks performed. Compared to measured METs, normative values underestimated walking leisurely (0.87 ± 0.12 METs) walking briskly (0.87 ± 0.12 METs ), and bed making (1.07 ± 0.10 METs ), but overestimated gardening (1.46 ± 0.12 METs) and climbing stairs (0.73 ± 0.18). Participants with impairments had significantly lower METs while gardening, vacuuming/sweeping, stair climbing, and walking briskly. However, when METs were adjusted for performance speed the metabolic costs were 16–27% higher for those with mobility impairments. CONCLUSION Compared to normative values, metabolic costs of daily activities are substantially different in older adults and having mobility impairments increases this metabolic cost. These results may have implications for practitioners to appropriately prescribe daily physical activities for healthy and mobility impaired older adults. PMID:22091979

    Theoretical models and experimental studies of bone remodeling suggest that bone density and structure are influenced by local cyclic skeletal tissue stress and strain histories. Estimation of long-term loading histories in humans is usually achieved by assessment of physical activity level by questionnaires, logbooks, and pedometers, since the majority of lower limb cyclic loading occurs during walking and running. These methods provide some indication of the mechanical loading history, but fail to consider the true magnitude of the lower limb skeletal forces generated by various daily activities. These techniques cannot account for individual gait characteristics, gait speed, and unpredictable high loading events that may influence bone mass significantly. We have developed portable instrumentation to measure and record the vertical component of the ground reaction force (GRFz) during normal daily activity. This equipment allows long-term quantitative monitoring of musculoskeletal loads, which in conjunction with bone mineral density assessments, promises to elucidate the relationship between skeletal stresses and bone remodeling.

    Wrist activity was monitored continuously for one year in a woman who went about her normal life. The year of data were analyzed for changes and rhythms--daily, weekly, menstrual, lunar, annual. For each day, average motions/5 minutes, activity onset, activity offset, alpha (duration of activity), and acrophase were measured. Periodograms and average daily wave forms were calculated. Well-defined, entrained, daily rest-activity cycles were observed throughout the year with periods close to 24 hours. There was weekend delay (0.7 hours) in onset, weekend decrease in alpha (1.0 hours), and weekend advance of acrophase (0.4 hours). Motions/5 minutes decreased 9%, onsets were 0.3 hours later, and alphas were 0.4 hours shorter on menstrual cycle days 8 through 18 which should have encompassed the time of ovulation. Lunar phase had no effect. Annual changes in onset (1.1 hours), offset (1.2 hours), and acrophase (1.1 hours) were attributed to the 1-hour change between standard and daylight savings time.

    Background This study analyzes Chicago-area weather effects on objectively measured physical activity over a three year period among a cohort of 241 participants in an on-going arthritis physical activity trial. Methods Uniaxial accelerometer counts and interview data were analyzed for up to six weekly study waves involving 4823 days of wear. The effects of temperature, rainfall, snowfall and daylight hours were analyzed after controlling for participant characteristics, day of the week, and daily accelerometer wear hours in a mixed effects linear regression model. Results Daylight hours, mean daily temperature <20 or ≥ 75 degrees and light or heavy rainfall (but not snowfall) were all significantly associated with lower physical activity after controlling for the significant effects of weekends, accelerometer wear hours, age, sex, type of arthritis, employment, Hispanic ethnicity, obesity, and SF36 physical and mental health scores. Conclusions The cumulative effects of weather are reflected in a 38.3% mean monthly difference in daily counts between November and June, reflecting over three additional hours of sedentary time. Physical activity promotion programs for older persons with chronic conditions need lifestyle physical activity plans adapted to weather extremes. PMID:21885884

    Daily aboveground activity of European ground squirrels (Spermophilus citellus) in their natural habitat was recorded with a visual scanning procedure during the active seasons of 1992 and 1993. Activity patterns were analyzed with respect to time of year and to the animal's reproductive state. Aboveground activity started on average 3.9 h (SD 0.6 h, n = 37 days) after civil twilight at dawn and ended on average 3.2 h (SD 0.9 h, n = 37 days) before civil twilight at dusk. Between onset and offset of activity, 54% was spent aboveground, of which 73% was spent foraging. Activity patterns were influenced by photoperiod, rainfall, and by reproductive state. During mating, reproductively active males started activity earlier than females and reproductively inactive males. For females, time spent foraging was high during lactation. The midpoint of daily activity was at 12:16 h (SD 0.37 h, n = 37 days). Activity patterns of European ground squirrels thus appear robustly positioned in the middle of the photoperiod. PMID:15129824

    The literature reports an association between neighbourhood deprivation and individual depression after adjustment for individual factors. The present paper investigates whether vulnerability to neighbourhood features is influenced by individual "activity space" (i.e., the space within which people move about or travel in the course of their daily activities). It can be assumed that a deprived residential environment can exert a stronger influence on the mental health of people whose activity space is limited to their neighbourhood of residence, since their exposure to their neighbourhood would be greater. Moreover, we studied the relationship between activity space size and depression. A limited activity space could indeed reflect spatial and social confinement and thus be associated with a higher risk of being depressed, or, conversely, it could be linked to a deep attachment to the neighbourhood of residence and thus be associated with a lower risk of being depressed. Multilevel logistic regression analyses of a representative sample consisting of 3011 inhabitants surveyed in 2005 in the Paris, France metropolitan area and nested within 50 census blocks showed, after adjusting for individual-level variables, that people living in deprived neighbourhoods were significantly more depressed that those living in more advantaged neighbourhoods. We also observed a statistically significant cross-level interaction between activity space and neighbourhood deprivation, as they relate to depression. Living in a deprived neighbourhood had a stronger and statistically significant effect on depression in people whose activity space was limited to their neighbourhood than in those whose daily travels extended beyond it. In addition, a limited activity space appeared to be a protective factor with regard to depression for people living in advantaged neighbourhoods and a risk factor for those living in deprived neighbourhoods. It could therefore be useful to take activity space

    In the 'Des Vieux Arbres' ecological reserve situated within northwestern Quebec, 40 band dendrometers were installed on 7 of the major boreal tree species. The late Spring-early Summer daily radial activity registered in 1997 was related to daily weather variables. For each tree species, the daily mean i) cumulative radial increment and ii) radial activity indexed series obtained by first-difference standardization were analyzed. The results indicate the existence of strong similarities among the 7 species. All showed strong synchronous fluctuations in radius during late winter and early spring. This period ended with a short but sharp increase in radial increments that marked the passage of water into the stem. This initial swelling, less obvious in Pinus species was followed by a prolonged period of little change in radial activity. Meteorological data indicated that air temperature was positively related to stem swelling during the late winter-early spring period. Both air and soil temperatures became negatively related to radial expansion once the passage of water has occurred in the stem. Starting in early June, all species registered a sustained increase in radial increments possibly associated with active cell division. After this, radial expansion was negatively related to air temperature and positively to rainfall. PMID:11339696

    Autism spectrum disorder (ASD) indicates several neurodevelopmental impairments which may end in impairments in motor or physical activities. Daily physical activity involvement was investigated in a total of 83 children (52 boys and 31 girls) with ASD aged 6–15 years. Results indicated that only 10 (12%) of children with ASD were physically active. Children were predominantly engaged in solitary play rather than social play activities. Gender, family income, and household structure were found to be associated with activity scores. Financial burden and lack of opportunities were noted as the leading barriers to physical activities. In conclusion, findings indicated a low rate of physical activity participation in children with ASD that is closely associated with sociodemographic variables. PMID:26171247

    An abandoned pentachlorophenol plant and nearby area in southern Taiwan was heavily contaminated by dioxins, impurities formed in the PCP production process. The investigation showed that the average serum PCDD/Fs of residents living nearby area (62.5 pg WHO-TEQ/g lipid) was higher than those living in the non-polluted area (22.5 and 18.2 pg WHO-TEQ/g lipid) (P<0.05). In biota samples, average PCDD/F of milkfish in sea reservoir (28.3 pg WHO-TEQ/g) was higher than those in the nearby fish farm (0.15 pg WHO-TEQ/g), and Tilapia and shrimp showed the similar trend. The average daily PCDD/Fs intake of 38% participants was higher than 4 pg WHO-TEQ/kg/day suggested by the world health organization. Serum PCDD/F was positively associated with average daily intake (ADI) after adjustment for age, sex, BMI, and smoking status. In addition, a prospective cohort study is suggested to determine the long-term health effects on the people living near factory. PMID:16213641

    Mobile health tools that enable clinicians and researchers to monitor the type, quantity, and quality of everyday activities of patients and trial participants have long been needed to improve daily care, design more clinically meaningful randomized trials of interventions, and establish cost-effective, evidence-based practices. Inexpensive, unobtrusive wireless sensors, including accelerometers, gyroscopes, and pressure-sensitive textiles, combined with Internet-based communications and machine-learning algorithms trained to recognize upper- and lower-extremity movements, have begun to fulfill this need. Continuous data from ankle triaxial accelerometers, for example, can be transmitted from the home and community via WiFi or a smartphone to a remote data analysis server. Reports can include the walking speed and duration of every bout of ambulation, spatiotemporal symmetries between the legs, and the type, duration, and energy used during exercise. For daily care, this readily accessible flow of real-world information allows clinicians to monitor the amount and quality of exercise for risk factor management and compliance in the practice of skills. Feedback may motivate better self-management as well as serve home-based rehabilitation efforts. Monitoring patients with chronic diseases and after hospitalization or the start of new medications for a decline in daily activity may help detect medical complications before rehospitalization becomes necessary. For clinical trials, repeated laboratory-quality assessments of key activities in the community, rather than by clinic testing, self-report, and ordinal scales, may reduce the cost and burden of travel, improve recruitment and retention, and capture more reliable, valid, and responsive ratio-scaled outcome measures that are not mere surrogates for changes in daily impairment, disability, and functioning.

    The objective of our study was the definition of testing scenarios for knee wear simulation under various highly demanding daily activities of patients after total knee arthroplasty. This was mainly based on a review of published data on knee kinematics and kinetics followed by the evaluation of the accuracy and precision of a new experimental setup. We combined tibio-femoral load and kinematic data reported in the literature to develop deep squatting loading profiles for simulator input. A servo-hydraulic knee wear simulator was customised with a capability of a maximum flexion of 120°, a tibio-femoral load of 5000N, an anterior-posterior (AP) shear force of ±1000N and an internal-external (IE) rotational torque of ±50Nm to simulate highly demanding patient activities. During the evaluation of the newly configurated simulator the ability of the test machine to apply the required load and torque profiles and the flexion kinematics in a precise manner was examined by nominal-actual profile comparisons monitored periodically during subsequent knee wear simulation. For the flexion kinematics under displacement control a delayed actuator response of approximately 0.05s was inevitable due to the inertia of masses in movement of the coupled knee wear stations 1-3 during all applied activities. The axial load and IE torque is applied in an effective manner without substantial deviations between nominal and actual load and torque profiles. During the first third of the motion cycle a marked deviation between nominal and actual AP shear load profiles has to be noticed but without any expected measurable effect on the latter wear simulation due to the fact that the load values are well within the peak magnitude of the nominal load amplitude. In conclusion the described testing method will be an important tool to have more realistic knee wear simulations based on load conditions of the knee joint during activities of daily living.

    Objective: Prospective memory (PM), that is, the ability to keep in memory and carry out intentions in the future, is reported to be impaired in individuals with Parkinson’s disease (PD). PM failure may be also associated with reduced daily living functioning in these patients. Little is known, however, about the relationship between mild cognitive impairment (MCI) and time-based PM functioning in PD patients and the possible impact of PM deficits on patients’ autonomy in daily living. Here we aimed to investigate whether MCI associated with PD affects time-based PM. We also wished to determine whether PM impairment accounts for reduced autonomous management of medication in these patients. Method: The study included 48 PD patients with MCI, 33 PD patients without cognitive disorders (PDN) and 20 healthy controls. The time-based PM procedure required that subjects perform an action after a fixed time. The PM procedure was incorporated in the standard neuropsychological assessment. One score was computed for the ability to retrieve the intention (prospective component) and one for remembering the action to be executed (retrospective component). The Pill Questionnaire was administered to assess the ability to manage medication. Results: PD patients with MCI performed less accurately in the PM procedure than HC and tended to perform poorer than PDN. Moreover, in PD patients with MCI, accuracy on the prospective component of the PM task and performance on the Modified Card Sorting Test significantly predicted the ability to manage medication. Conclusions: Results document that reduced efficiency of time-based PM processes in PD is specifically related to the presence of MCI. The same data indicate that PM weakness may be associated with impaired daily living functioning and decreased autonomy. PMID:26106317

    Research on the motivation of stakeholders to integrate physical activity into daily school life is limited. The purpose was to examine the motivation of stakeholders to participate in a world record physical activity event and whether motivation was associated with future intention to use activity breaks during the daily school life and future participation in a similar event. After the 2012 JAM (Just-a-Minute) World Record event, 686 adults (591 women; 76.1% participated for children <10 years) completed measures of motivational regulations and future intention to (a) use the activity breaks and (b) participate in the event. High intrinsic motivation and low extrinsic motivation and amotivation for participation in the next event were reported. Hierarchical regression analysis, controlling for age, gender, and occupation, showed that intrinsic forms of motivation positively predicted, whereas amotivation negatively predicted, future intention to participate in the event and use the activity breaks. Multivariate analyses of variance revealed that school-related participants were more intrinsically motivated and intended to use the activity breaks and repeat the event more than those who were not affiliated with a school. Nonschool participants reported higher extrinsic motivation and amotivation than school-related participants. PMID:25001232

To date, there is limited data of normal canine 3D knee kinematics during daily activities. The objective of this study was to characterize 3D in-vivo femorotibial kinematics in normal dogs during commonly performed daily activities. Using single-plane fluoroscopy, six normal dogs were imaged performing walk, trot, sit, and stair ascent activities. CT-generated bone models were used for kinematic measurement using a 3D-to-2D model registration technique. Increasing knee flexion angle was typically associated with increasing tibial internal rotation, abduction and anterior translation during all four activities. The precise relationship between flexion angle and these movements varied both within and between activities. Significant differences in axial rotation and coronal angulation were found at the same flexion angle during different phases of the walk and trot. This was also found with anterior tibial translation during the trot only. Normal canine knees accommodate motion in all planes; precise kinematics within this envelope of motion are activity dependent. This data establishes the characteristics of normal 3D femorotibial joint kinematics in dogs that can be used as a comparison for future studies. PMID:25982776

    People on the Island of Hawai'i face many hazards that come with living on or near active volcanoes. These include lava flows, explosive eruptions, volcanic smog, damaging earthquakes, and tsunamis (giant seawaves). As the population of the island grows, the task of reducing the risk from volcano hazards becomes increasingly difficult. To help protect lives and property, U.S. Geological Survey (USGS) scientists at the Hawaiian Volcano Observatory closely monitor and study Hawai'i's volcanoes and issue timely warnings of hazardous activity.

    The aims of the study were (a) to examine the associations between the daily physical activity (PA) of 8- to 9-year-old children and their parents, and (b) to examine what effect the child's daily PA has on its cardiorespiratory fitness (CRF), body mass index (BMI), and health-related quality of life (HRQoL). The sample consisted of 1021 persons [351 children (8.73 ± 0.69 years in age) and 670 parents]. Pedometers were used to evaluate PA in parents and their children over the course of 4 days (Thursday-Sunday), with the instructions on how to wear the pedometers for 24 h a day. Also evaluated were height, weight, BMI, CRF (via the maximal multistage 20-m shuttle run test), and HRQoL (via the EQ-5D-Y questionnaire). Associations between these variables were studied using path model techniques. The father's PA predicts his child's daily PA. This in turn predicts the child's lower BMI, CRF, and perceived quality of life. The findings suggest that the role model of a physically active father positively influences the child's PA habits, and hence that the family environment can have an important part to play in promoting health.

  15. A Predictive Model of Daily Seismic Activity Induced by Mining, Developed with Data Mining Methods

    The article presents the development and evaluation of a predictive classification model of daily seismic energy emissions induced by longwall mining in sector XVI of the Piast coal mine in Poland. The model uses data on tremor energy, basic characteristics of the longwall face and mined output in this sector over the period from July 1987 to March 2011. The predicted binary variable is the occurrence of a daily sum of tremor seismic energies in a longwall that is greater than or equal to the threshold value of 105 J. Three data mining analytical methods were applied: logistic regression,neural networks, and stochastic gradient boosted trees. The boosted trees model was chosen as the best for the purposes of the prediction. The validation sample results showed its good predictive capability, taking the complex nature of the phenomenon into account. This may indicate the applied model's suitability for a sequential, short-term prediction of mining induced seismic activity.

    The daily dynamics of cellulase activity was studied during 27 days by the cellophane membrane method on soils managed using the conventional high-input farming system (application of mineral fertilizers and pesticides) and the biological conservation farming system (application of organic fertilizers alone) in a microfield experiment. The regular oscillatory dynamics of the cellulase activity were revealed and confirmed by the harmonic (Fourier) analysis. The oscillatory dynamics of the cellulase activity had a self-oscillatory nature and was not directly caused by the disturbing impacts of both the uncontrolled (natural) changes in the temperature and moisture (rainfall) and the controlled ones (the application of different fertilizers). The disturbing impacts affected the oscillation amplitude of the cellulase activity but not the frequency (periods) of the oscillations. The periodic oscillations of the cellulase activity were more significant in the soil under the high-input management compared to the soil under the biological farming system.

    Background Promoting physical activity is a public health priority in most industrial countries, and physical function is an important factor when taking into consideration older people’s self-care and health. Despite the increasing challenges associated with urbanization and the aging population, urban life appears to be positive in many ways for urban dwellers. However, the manner in which older people live in urban settings and how this influences their ability to take care of themselves should be considered important knowledge for health professionals and politicians to acquire. The aim of this study was to describe the lived experiences of self-care and features that may influence health and self-care among older urban home-dwelling individuals who are physically active. Methods Ten subjects, three women and seven men, who were aged 65–82 years and identified to be physically active, were interviewed. The interviews were recorded, transcribed verbatim, and analyzed according to the descriptive phenomenological method devised by Giorgi. Results Our findings showed beneficial self-care. The participants lived active everyday lives and were frequently physically active. They were part of a supportive, inclusive, and promoting fellowship, and they had the opportunity to travel. They utilized their competence and experienced making themselves useful. It was a privilege to be part of a family life as a husband, wife, parent, and/or a grandparent. They acknowledged physical and mental limitations, yet they felt they were in good health. Conclusion Health professionals and politicians should identify places where fellowship and relationships can be built, as well as encourage older people to use their competence by engagement in volunteering. These interventions are important to support older people’s self-care and health. This may also be a way to reduce ageism in Western societies. PMID:23390363

  18. Effects of temperature and photoperiod on daily activity rhythms of Lutzomyia longipalpis (Diptera: Psychodidae)

    2014-01-01

    Background Insect vectors have been established as models in Chronobiology for many decades, and recent studies have demonstrated a close relationship between the circadian clock machinery, daily rhythms of activity and vectorial capacity. Lutzomyia longipalpis, the primary vector of Leishmania (Leishmania) infantum in the New World, is reported to have crepuscular/nocturnal activity in the wild. However, most of these studies applied hourly CDC trap captures, which is a good indicative of L. longipalpis behaviour, but has limited accuracy due to the inability to record the daily activity of a single insect during consecutive days. In addition, very little is known about the activity pattern of L. longipalpis under seasonal variations of average temperature and day length in controlled laboratory conditions. Methods We recorded the locomotor activity of L. longipalpis males under different artificial regimes of temperature and photoperiod. First, in order to test the effects of temperature on the activity, sandflies were submitted to regimes of light/dark cycles similar to the equinox photoperiod (LD 12:12) combined with different constant temperatures (20°C, 25°C and 30°C). In addition, we recorded sandfly locomotor activity under a mild constant temperature (25°C with different day length regimes: 8 hours, 12 hours and 16 hours). Results L. longipalpis exhibited more activity at night, initiating dusk-related activity (onset time) at higher rather than lower temperatures. In parallel, changes of photoperiod affected anticipation as well as all the patterns of activity (onset, peak and offset time). However, under LD 16:08, sandflies presented the earliest values of maximum peak and offset times, contrary to other regimes. Conclusions Herein, we showed that light and temperature modulate L. longipalpis behaviour under controlled laboratory conditions, suggesting that sandflies might use environmental information to sustain their crepuscular

    Hormone signalling during critical periods organises the adult circadian timekeeping system by altering adult hormone sensitivity and shaping fundamental properties of circadian rhythmicity. However, the timing of when developmental oestrogens modify the timekeeping system is poorly understood. To test the hypothesis that alterations in postnatal oestrogenic signalling organise adult daily activity rhythms, we utilised aromatase knockout mice (ArKO), which lack the enzyme required for oestradiol synthesis. ArKO and wild-type (WT) males and females were administered either oestradiol (E) or oil (OIL) daily for the first 5 postnatal days (p1-5E and p1-5OIL , respectively) because this time encompasses the emergence of clock gene rhythmicity and light responsiveness in the suprachiasmatic nucleus, a bilateral hypothalamic structure regarded as the 'master oscillator'. After sexual maturation, gonadectomy and exogenous oestradiol supplementation, locomotor parameters were assessed. We determined that altered oestrogenic signalling in early life exerts organisational control over the expression of daily and circadian activity rhythms in adult mice. Specifically, p1-5E reduced total wheel running activity in male and female ArKO and female WT mice but had no effect on WT male activity levels. In females, wheel running was consolidated by p1-5E to the early versus late evening, a phenomenon characteristic of male mice. The time of peak activity was advanced by p1-5E in WT and ArKO females but not males. P1-5E shortened the length of the active phase (alpha) in WT males but had no effect on ArKO males or females of either genotypes. Finally, p1-5E altered the magnitude of photic-induced shifts, suggesting that developmental oestrogenic signalling impacts adult circadian functions. In the present study, we further define both a critical period of development of the adult timekeeping system and the role that oestrogenic signalling plays in the expression of daily and

    The daily locomotor and melatonin rhythms of the Senegal sole, a benthonic species of increasing interest in aquaculture, are still unknown, despite the fact that such knowledge is of prime importance for optimising its production. The aim of the present research was therefore to investigate the daily rhythms of locomotor activity and melatonin in the Senegal sole. For this purpose, the individual locomotor activity rhythms of fish were registered using a photocell. Plasma and ocular melatonin rhythms were studied in animals reared in circular tanks placed in earth under an LD 12:12 light regime and 16-18 degrees C temperature range (spring equinox). Blood and eye samples were taken every 3 h during a complete 24-h cycle. The impact of a light pulse in the middle of the dark period (MD) on plasma melatonin was also studied. Locomotor activity was mainly nocturnal, with 84.3% of the total activity occurring during darkness. The levels of plasma melatonin were higher at night (55 pg/ml) than during the day (2 pg/ml), while ocular melatonin levels appeared to be arrhythmic. Both weight and melatonin content were found to be significantly higher in the left eye in relation to the right eye. A light pulse in MD provoked a significant decrease in plasma melatonin levels. In summary, photoperiod is a key factor in synchronizing locomotor activity and melatonin rhythms in the Senegal sole, whose nocturnal habits should be taken into account for their rearing by aquaculture.

    Participation in childhood daily functional performance was examined in 78 children: 44 with sensory modulation disorder (SMD); (33 males, 11 females; mean age 7y 6mo [SD 1.20]) and 34 without SMD (18 males, 16 females; mean age 7y 8mo [SD 1.33]). Group classification was determined using two measures: the Short Sensory Profile (SSP) and the Full-form Sensory Profile. Parents completed a battery of caregiver questionnaires. Children with SMD scored significantly lower on all three participation scales than the control group. A high correlation was observed between level of activity performance of the Participation in Childhood Occupations Questionnaire (PICO-Q) and the SSP, and a moderate correlation was observed between the Enjoyment of Performance of the PICO-Q and the SSP. A low correlation was observed between Frequency of Performance of the PICO-Q and the SSP. Logistic regression indicated that all three participation scales (level of activity performance, level of enjoyment of the activity, and frequency of performance of the activity) are significantly associated with group classification, with odds ratios of 3.13, 2.05, and 1.73 respectively. These findings are the first, to our knowledge, to confirm claims of limited participation in daily activities among children with SMD. Our results have significant clinical implications and provide support for the need for practitioners and caregivers of children with SMD to facilitate participation.

    Consumption of high-fat diet acutely alters the daily rhythm of eating behavior and circadian organization (the phase relationship between oscillators in central and peripheral tissues) in mice. Voluntary wheel-running activity counteracts the obesogenic effects of high-fat diet and also modulates circadian rhythms in mice. In this study, we sought to determine whether voluntary wheel-running activity could prevent the proximate effects of high-fat diet consumption on circadian organization and behavioral rhythms in mice. Mice were housed with locked or freely rotating running wheels and fed chow or high-fat diet for 1 week and rhythms of locomotor activity, eating behavior, and molecular timekeeping (PERIOD2::LUCIFERASE luminescence rhythms) in ex vivo tissues were measured. Wheel-running activity delayed the phase of the liver rhythm by 4 h in both chow- and high-fat diet-fed mice. The delayed liver phase was specific to wheel-running activity since an enriched environment without the running wheel did not alter the phase of the liver rhythm. In addition, wheel-running activity modulated the effect of high-fat diet consumption on the daily rhythm of eating behavior. While high-fat diet consumption caused eating events to be more evenly dispersed across the 24 h-day in both locked-wheel and wheel-running mice, the effect of high-fat diet was much less pronounced in wheel-running mice. Together these data demonstrate that wheel-running activity is a salient factor that modulates liver phase and eating behavior rhythms in both chow- and high-fat-diet fed mice. Wheel-running activity in mice is both a source of exercise and a self-motivating, rewarding behavior. Understanding the putative reward-related mechanisms whereby wheel-running activity alters circadian rhythms could have implications for human obesity since palatable food and exercise may modulate similar reward circuits.

    The purpose of this study was to describe quality-of-life aspects in a group of patients (n = 99) suffering from peripheral vestibular disorder, using three different self-rated instruments, the Vertigo Symptom Scale (VSS), the Vertigo Handicap Questionnaire (VHQ) and the Sickness Impact Profile (SIP). The results showed that the type of dizziness that most influenced the quality-of-life aspects were: frequent short- or long-term dizziness, nausea, and the feeling that the ground was distant or as though the patient were walking on clouds. However, several of the impairments in daily life were neither related to the disease itself nor the demographic data. This verifies the necessity of investigating other factors such as personality and coping capacity. The results of this study also demonstrate the patients' need of psychosocial support. A comprehensive assessment and evaluation is important in order to identify each patient's needs.

    Interpersonal touch seems to promote physical health through its effects on stress-sensitive parameters. However, less is known about the psychological effects of touch. The present study investigates associations between touch and romantic partners' affective state in daily life. We hypothesized that this association is established by promoting the recipient's experience of intimacy. Both partners of 102 dating couples completed an electronic diary 4 times a day during 1 week. Multilevel analyses revealed that touch was associated with enhanced affect in the partner. This association was mediated by the partner's psychological intimacy. Touch was also associated with intimacy and positive affect in the actor. Finally, participants who were touched more often during the diary study week reported better psychological well-being 6 months later. This study provides evidence that intimate partners benefit from touch on a psychological level, conveying a sense of strengthened bonds between them that enhances affect and well-being.

    Day-to-day variability and stability of children’s physical activity levels across days of the week are not well understood. Our aims were to examine the day-to-day variability of moderate-to-vigorous physical activity (MVPA), to determine factors influencing the day-to-day variability of MVPA and to estimate stability of MVPA in children. The sample comprises 686 Portuguese children (10 years of age). MVPA was assessed with an accelerometer, and BMI was computed from measured height and weight. Daily changes in MVPA and their correlates (gender, BMI, and maturity) were modeled with a multilevel approach, and tracking was calculated using Foulkes & Davies γ. A total of 51.3% of boys and 26.2% of girls achieved 60 min/day of MVPA on average. Daily MVPA was lower during the weekend (23.6% of boys and 13.6% of girls comply with the recommended 60 min/day of MVPA) compared to weekdays (60.8% and 35.4%, boys and girls, respectively). Normal weight children were more active than obese children and no effect was found for biological maturation. Tracking is low in both boys (γ = 0.59 ± 0.01) and girls (γ = 0.56 ± 0.01). Children’s MVPA levels during a week are highly unstable. In summary, boys are more active than girls, maturation does not affect their MVPA, and obese children are less likely to meet 60 min/day of MVPA. These results highlight the importance of providing opportunities for increasing children’s daily MVPA on all days of week, especially on the weekend. PMID:26262632

    The aim of the study was to describe how patients suffering from chronic heart failure conceived their physical limitations in daily life activities. An explorative and qualitative design with a phenomenographic approach was chosen, a total of 15 patients were interviewed. The findings indicate that participants perceived a variety of structural aspects pertaining to physical limitations in activities of daily life which resulted in four referential aspects. Need of finding practical solutions in daily life focused on how life had to be changed and other ways of performing activities of daily life had to be invented. Having realistic expectations about the future was characterised by belief that the future itself would be marked by change in physical functioning, but an incentive to maintain functions and activities ensured good quality of or even increased capacity in daily life. Not believing in one's own ability included the perception of having no opportunity to improve ability to perform activities of daily life. There were perceptions of undesired passivity, undefined fear of straining themselves or performing activities that could endanger their health in addition to uncertainty about the future. In Losing one's social role in daily life, participants described losing their social network and their position in society and family because of limited physical capacity. A lack of important issues, mental and physical, occurred when physical capacity was lost. In conclusion, patients suffering from chronic heart failure found new solutions to manage activities in daily life, including willingness to change focus and identify other ways of doing important things. Patients had an incentive to maintain functions and activities to ensure a good quality of and strengthen their physical capacity in daily life. Inability to trust in their physical capacity in combination with experienced limitations in daily life prevented patients from attempting to increase activities

    Background Few studies have investigated the experiences of living with pelvic girdle pain (PGP) and its impact on pregnant women’s lives. To address this gap in knowledge, this study investigates the experiences of women living with PGP during pregnancy. Methods A purposive sample, of nine pregnant women with diagnosed PGP, were interviewed about their experiences. Interviews were recorded, transcribed to text and analysed using a Grounded Theory approach. Results The core category that evolved from the analysis of experiences of living with PGP in pregnancy was “struggling with daily life and enduring pain”. Three properties addressing the actions caused by PGP were identified: i) grasping the incomprehensible; ii) balancing support and dependence and iii) managing the losses. These experiences expressed by the informants constitute a basis for the consequences of PGP: iv) enduring pain; v) being a burden; vi) calculating the risks and the experiences of the informants as vii) abdicating as a mother. Finally, the informants’ experiences of the consequences regarding the current pregnancy and any potential future pregnancies is presented in viii) paying the price and reconsidering the future. A conceptual model of the actions and consequences experienced by the pregnant informants living with PGP is presented. Conclusions PGP during pregnancy greatly affects the informant’s experiences of her pregnancy, her roles in relationships, and her social context. For informants with young children, PGP negatively affects the role of being a mother, a situation that further strains the experience. As the constant pain disturbs most aspects of the lives of the informants, improvements in the treatment of PGP is of importance as to increase the quality of life. This pregnancy-related condition is prevalent and must be considered a major public health concern during pregnancy. PMID:23668823

    Temporal patterns of quiescent electromyography termed 'gaps' were investigated in young and old men and women for a discrete task and daily activity. Gaps in women (1.3±3.2) and old adults (1.5±3.4) were fewer compared with men (4.7±6.7) and young adults (4.6±6.9) for the discrete task (p<0.001). Gap duration was shorter for women (0.1±0.2s) and old adults (0.1±0.3s) compared with men (0.2±0.3s) and young adults (0.2±0.2s) (p<0.01). For daily activity, gap number was similar with age, but gap duration and percentage of total time occupied by gaps were less in old compared with young adults (50%), and in women compared with men (43%) (p<0.001). Results suggest gap activity is sensitive to type and duration of activity and that old adults and women demonstrate less quiescent electromyography than young adults and men.

    Viperid snakes are widely distributed in the South America and the greater distribution range of the family is found at the Crotalinae subfamily. Despite the abundance of this snakes along their geographic distribution, some ecological aspects remain unknown, principally at subtropical areas. In the present study, we evaluated the activity (daily and seasonal) and the use of the habitat by Bothrops diporus, B. jararaca and B. jararacussu, in an Atlantic Forest area at southern Brazil. We observed higher incidence of viperid snakes during the months with higher temperatures, while no snakes were found during the months with lower temperatures. The data suggest the minimum temperature as environmental variable with the greatest influence on the seasonal activity of this species. Considering the daily activity, we observed a tendency of snakes to avoid the warmest hours. Bothrops jararacussu tend to avoid open areas, being registered only inside and at the edges of the forest. We compared our results with previous studies realized at tropical areas and we suggest the observed seasonal activity as an evolutive response, despite the influence of the different environmental variables, according to the occurence region.

    Objectives: To assess the test–retest reliability and convergent validity of daily physical activity measures during inpatient spinal cord injury rehabilitation. Design: Observational study. Setting: Two inpatient spinal cord injury rehabilitation centres. Subjects: Participants (n = 106) were recruited from consecutive admissions to rehabilitation. Methods: Physical activity during inpatient spinal cord injury rehabilitation stay was recorded on two days via (1) wrist accelerometer, (2) hip accelerometer if ambulatory, and (3) self-report (Physical Activity Recall Assessment for People with Spinal Cord Injury questionnaire). Spearman’s correlations and Bland–Altman plots were utilized for test–retest reliability. Correlations between physical activity measures and clinical measures (functional independence, hand function, and ambulation) were performed. Results: Correlations for physical activity measures between Day 1 and Day 2 were moderate to high (ρ = 0.53–0.89). Bland–Altman plots showed minimal bias and more within-subject differences in more active individuals and wide limits of agreement. None of these three physical activity measures correlated with one another. A moderate correlation was found between wrist accelerometry counts and grip strength (ρ = 0.58) and between step counts and measures of ambulation (ρ = 0.62). Functional independence was related to wrist accelerometry (ρ = 0.70) and step counts (ρ = 0.56), but not with self-report. Conclusion: The test–retest reliability and convergent validity of the instrumented measures suggest that wrist and hip accelerometers are appropriate tools for use in research studies of daily physical activity in the spinal cord injury rehabilitation setting but are too variable for individual use.

Conclusion: The test–retest reliability and convergent validity of the instrumented measures suggest that wrist and hip accelerometers are appropriate tools for use in research studies of daily physical activity in the spinal cord injury rehabilitation setting but are too variable for individual use.

    Using Ecological Momentary Assessment, the within patient associations between drive for thinness, emotional states, momentary urge to be physically active and physical activity were studied in 32 inpatients with an eating disorder. Participants received an electronic device and had to indicate at nine random times a day during 1 week their momentary drive for thinness, positive and negative emotional states and their urge to be physically active and physical activity. Multilevel analyses indicated that patients with higher mean levels for urge to be physically active were characterized by lower body mass index (BMI) and chronically negative affect whereas patients with higher mean levels for physical activity were characterized by lower BMI and higher dispositions for drive for thinness. In addition, within patient relations between drive for thinness and urge to be physically active were moderated by BMI and chronically negative affect whereas within patient relations between drive for thinness and physical activity were moderated by BMI. Finally, also positive emotional states were significantly associated with physical activity within patients. By using a daily process design, characteristics of physical activity were revealed that have not been identified with assessment methods that have a lower time resolution.

    A large group of individuals suffering from mental illness are parents living with their children. These children are invisible in the health care even though at risk for illhealth. The aim of this metasynthesis was to advance knowledge of how children of parents with mental illness experience their lives, thus contributing to the evidence of this phenomenon. The metasynthesis is following Sandelowski and Barroso's guidelines. Literature searches covering the years 2000 to 2013 resulted in 22 reports which were synthesised into the theme 'navigating in an unpredictable everyday life' and the metaphor compass. Children of parents with mental illness irrespective of age are responsible, loving and worrying children who want to do everything to help and support. Children feel shame when the parent behaves differently, and they conceal their family life being afraid of stigmatisation and bullying. When their parent becomes ill, they distance to protect themselves. The children cope through information, knowledge, frankness and trustful relationships. These children need support from healthcare services because they subjugate own needs in favour of the parental needs, they should be encouraged to talk about their family situation, and especially, young children should to be child-like, playing and seeing friends.

    Microbial biofilms grown utilizing electrodes as metabolic electron acceptors or donors are a new class of biomaterials with distinct electronic properties. Here we report that electron transport through living electrode-grown Geobacter sulfurreducens biofilms is a thermally activated process with incoherent redox conductivity. The temperature dependency of this process is consistent with electron-transfer reactions involving hemes of c-type cytochromes known to play important roles in G. sulfurreducens extracellular electron transport. While incoherent redox conductivity is ubiquitous in biological systems at molecular-length scales, it is unprecedented over distances it appears to occur through living G. sulfurreducens biofilms, which can exceed 100 microns in thickness.

    Summary Manipulation of protein kinase activity is widely used to dissect signaling pathways controlling physiological and pathological processes. Common methods often cannot provide the desired spatial and temporal resolution in control of kinase activity. Regulation of kinase activity by photocaged kinase inhibitors has been successfully used to achieve tight temporal and local control, but inhibitors are limited to inactivation of kinases, and often do not provide the desired specificity. Here we report detailed methods for light-mediated activation of kinases in living cells using engineered rapamycin-regulated kinases (RapR-kinases) in conjunction with a photocaged analog of rapamycin.

    In order to identify daily changes in digestive physiology in developing gilthead seabream larvae, the enzyme activity (trypsin, lipases and α-amylase) and gene expression (trypsinogen-try, chymotrypsinogen-ctrb, bile salt-activated lipase-cel1b, phospholipase A2-pla2 and α-amylase-amy2a) were measured during a 24h cycle in larvae reared under a 12h light/12h dark photoperiod. Larvae were sampled at 10, 18, 30 and 60days post-hatch. In each sampling day, larvae were sampled every 3h during a complete 24h cycle. The enzyme activity and gene expression exhibited a marked dependent behavior to the light/darkness cycle in all tested ages. The patterns of activity and expression of all tested enzymes were compared to the feeding pattern found in the same larvae, which showed a rhythmic feeding pattern with a strong light synchronization. In the four tested ages, the activities of trypsin, and to a lesser extent lipases and amylase, were related to feeding activity. Molecular expression of the pancreatic enzymes tended to increase during the night, probably as an anticipation of the forthcoming ingestion of food that will take place during the next light period. It follows that the enzymatic activities are being regulated at translational and/or post-translational level. The potential variability of enzyme secretion along the whole day is an important factor to take into account in future studies. A particularly striking consequence of the present results is the reliability of studies based in only one daily sample taken at the same hour of the day, as those focused to assess ontogeny of digestive enzymes.

    Physical activity has a positive impact on people's well-being, and it may also decrease the occurrence of chronic diseases. Activity recognition with wearable sensors can provide feedback to the user about his/her lifestyle regarding physical activity and sports, and thus, promote a more active lifestyle. So far, activity recognition has mostly been studied in supervised laboratory settings. The aim of this study was to examine how well the daily activities and sports performed by the subjects in unsupervised settings can be recognized compared to supervised settings. The activities were recognized by using a hybrid classifier combining a tree structure containing a priori knowledge and artificial neural networks, and also by using three reference classifiers. Activity data were collected for 68 h from 12 subjects, out of which the activity was supervised for 21 h and unsupervised for 47 h. Activities were recognized based on signal features from 3-D accelerometers on hip and wrist and GPS information. The activities included lying down, sitting and standing, walking, running, cycling with an exercise bike, rowing with a rowing machine, playing football, Nordic walking, and cycling with a regular bike. The total accuracy of the activity recognition using both supervised and unsupervised data was 89% that was only 1% unit lower than the accuracy of activity recognition using only supervised data. However, the accuracy decreased by 17% unit when only supervised data were used for training and only unsupervised data for validation, which emphasizes the need for out-of-laboratory data in the development of activity-recognition systems. The results support a vision of recognizing a wider spectrum, and more complex activities in real life settings. PMID:18270033

    Adult males and females of many insect species are expected to adjust their daily activity pattern in order to avoid stressful climatic conditions and increase the chances to encounter sexual partners. Using scan sampling methods associated with focal individual observations it was found that two satyrine butterflies of similar size and morphology, Hermeuptychia hermes (Fabricius) (Leptidoptera: Nymphalidae) and Paryphthimoides phronius (Godart), show completely different daily activity patterns on forest edges in southeastern Brazil. Hermeuptychia hermes presents one abundance peak in the morning and another in the late afternoon, while P. phronius abundance peaks in the mid-day, remaining stable until 1700 h. This difference is probably due to the occurrence of territorial behavior in the later species. The beginning of territorial defense by P. phronius males coincided with the time of new-born female activity. However, newly hatched females were not sexually receptive. The afternoon territoriality in male P. phronius may be in part related to mate acquisition. However, why the abundance of H. hermes decreases when the abundance of P. phronius increases is less clear.

    This study aims to answer the research question of "Are early onset aging conditions correlated to daily activity functions in youth and adults with Down syndrome (DS)?" A cross-sectional survey was employed to recruit 216 individuals with DS over 15 years of age in the analyses. A structured questionnaire included demographic data, brief self-reported aging conditions, Dementia Screening Questionnaire for Individuals with Intellectual Disabilities (DSQIID) and activity of daily living (ADL) scales were completed by the primary caregivers who were well-suited for providing information on the functioning conditions of the DS individuals. Results showed that the most five frequent aging conditions (sometimes, usually and always) included frailty (20.2%), vision problem (15.8%), loss of language ability (15.3%), sleep problem (14.9%) and memory impairment (14.5%). Other onset aging conditions included more chronic diseases (13.9%), hearing loss (13%), chewing ability and tooth loss (12.5%), incontinence (11.1%), depressive syndrome (7.7%), falls and gait disorder (7.2%), loss of taste and smell (7.2%). The data also showed scores of DSQIID, onset aging conditions and ADL has significant relationships each other in Pearson's correlation tests. Finally, multiple linear regression analyses indicated onset aging conditions (β=-0.735, p<0.001) can significantly predicted the variation in ADL scores after adjusting other factors (R(2)=0.381). This study suggests that the authority should initiate early intervention programs aim to improve healthy aging and ADL functions for people with DS. PMID:25462513

    About 40% of patients with obsessive-compulsive disorder (OCD) are said to have treatment-refractory symptoms and chronic course of illness in spite of cognitive-behavior therapy and pharmacotherapy. The present purpose was to investigate factors relevant to OCD patients' chronic course and disturbed daily functions in view of human basic needs based on Maslow's hierarchy of five basic needs. Case notes of 101 outpatients with OCD (47 men and 54 women who were 18 to 55 years old) and seen on a psychiatry unit of a general hospital were studied to explore their stressful situations and identify thwarted basic needs. 84 of the 101 patients had Love Needs, and Esteem Needs (n = 47) and Safety Needs (n = 45) were next. The Poor-functioning group mainly had histories with problems of Safety Needs (70.8%), while the Good-functioning group tended to mainly have problems of Esteem Needs (51.5%) rather than Safety Needs (33.3%). 57 patients (23 men and 34 women) who were treated for more than three months were divided into two groups according to their Global Assessment of Functioning score at the final assessment (cut-off point: 61); patients in the Good-functioning group tended to have problems of higher needs.

    Daily schedules of limited access to food, palatable high calorie snacks, water and salt can induce circadian rhythms of anticipatory locomotor activity in rats and mice. All of these stimuli are rewarding, but whether anticipation can be induced by neural correlates of reward independent of metabolic perturbations associated with manipulations of food and hydration is unclear. Three experiments were conducted to determine whether mating, a non-ingestive behavior that is potently rewarding, can induce circadian anticipatory activity rhythms in male rats provided scheduled daily access to steroid-primed estrous female rats. In Experiment 1, rats anticipated access to estrous females in the mid-light period, but also exhibited post-coital eating and running. In Experiment 2, post-coital eating and running were prevented and only a minority of rats exhibited anticipation. Rats allowed to see and smell estrous females showed no anticipation. In both experiments, all rats exhibited sustained behavioral arousal and multiple mounts and intromissions during every session, but ejaculated only every 2-3 days. In Experiment 3, the rats were given more time with individual females, late at night for 28 days, and then in the midday for 28 days. Ejaculation rates increased and anticipation was robust to night sessions and significant although weaker to day sessions. The anticipation rhythm persisted during 3 days of constant dark without mating. During anticipation of nocturnal mating, the rats exhibited a significant preference for a tube to the mating cage over a tube to a locked cage with mating cage litter. This apparent place preference was absent during anticipation of midday mating, which may reflect a daily rhythm of sexual reward. The results establish mating as a reward stimulus capable of inducing circadian rhythms of anticipatory behavior in the male rat, and reveal a critical role for ejaculation, a modulatory role for time of day, and a potential confound role for

    The transition from adolescence to adulthood is an important period for establishing behavioral patterns that affect long-term health and chronic disease risk. Nelson and colleagues speculated that developmental changes and changes in living situation may play an important role in the nutrition and physical activity behaviors of college students. Data from the University Life Study, a longitudinal study of college students that includes web-based surveys administered 14 consecutive days each semester, were used to examine fruit, vegetable, and sugared soda consumption, physical activity, and sedentary activity behaviors across seven semesters. Estimates for each semester were calculated to determine the frequency with which students consumed fruits, vegetables, and sugared soda, engaged in moderate to vigorous physical activity, and engaged in sedentary activities. Four models, estimated with HLM 6.04, were used to predict changes in these behaviors across the seven semesters. Living on or off campus was included to determine if this explained additional variance. Results indicated that few college students consumed fruits and vegetables or exercised at optimal levels during the seven semesters surveyed. Daily fruit and vegetable consumption and daily physical activity declined significantly from the first to the seventh semester. For both of these findings, living off campus exacerbated the problem. Average number of hours of sedentary behaviors declined over time, as did number of days on which at least one sugared soda was consumed. Living location did not explain additional variance in these positive trends. Implications for policy, practice, and future research are discussed. PMID:23232092

    Few longitudinal studies have assessed risk factors for pain outcomes in tumor-specific populations. Such studies are needed to improve clinical practice guidelines for cancer pain management over the course of treatment. Among patients with metastatic breast cancer, we assessed the impact of baseline clinical and demographic risk factors on patients reaching different pain severity and interference scores. We analyzed data originally collected in a clinical trial of two bisphosphonate therapies. Pain was measured by the Brief Pain Inventory (BPI) severity and interference with daily living 0-10 subscales. We fit univariate (per-cutpoint) and multivariate (cutpoints 3, 4, 5, 6, and 7 on the BPI) proportional hazards models to identify predictors of pain outcomes over 51 weeks among 1,124 women with metastatic breast cancer. Predictors included race, age, education, geographic region, performance status, chemotherapy versus hormonal therapy only, time from first bone metastasis to randomization, and previous skeletal-related event (SRE, e.g., fractures, spinal cord compression). Non-Caucasian women had greater hazards for reaching higher cutpoints (5 and above) on the severity scale than Caucasian women (hazard ratio [HR] for cutpoint 5 interaction term=1.76; 95% confidence interval [CI]=1.37-2.26). For the interference scale, these hazards were greater for those patients with restricted (versus active) baseline Eastern Cooperative Oncology Group (ECOG) performance status (HR for cutpoint 5 interaction term=2.51; 95% CI=2.01-3.13). In the multivariate severity model, other factors associated with higher pain severity were restricted baseline ECOG performance status, previous SRE, and not being employed full-time at baseline (HRs=1.70, 1.23, and 1.33, respectively). Our findings that non-Caucasian race and restricted performance status were associated with greater pain hazards over time confirm previous cross-sectional findings that these characteristics are pain

    AbstractIntrinsic daily or circadian rhythms arise through the outputs of the master circadian clock in the brain's suprachiasmatic nuclei (SCN) as well as circadian oscillators in other brain sites and peripheral tissues. SCN neurones contain an intracellular molecular clock that drives these neurones to exhibit pronounced day–night differences in their electrical properties. The epithalamic medial habenula (MHb) expresses clock genes, but little is known about the bioelectric properties of mouse MHb neurones and their potential circadian characteristics. Therefore, in this study we used a brain slice preparation containing the MHb to determine the basic electrical properties of mouse MHb neurones with whole-cell patch clamp electrophysiology, and investigated whether these vary across the day–night cycle. MHb neurones (n = 230) showed heterogeneity in electrophysiological state, ranging from highly depolarised cells (∼ −25 to −30 mV) that are silent with no membrane activity or display depolarised low-amplitude membrane oscillations, to neurones that were moderately hyperpolarised (∼40 mV) and spontaneously discharging action potentials. These electrical states were largely intrinsically regulated and were influenced by the activation of small-conductance calcium-activated potassium channels. When considered as one population, MHb neurones showed significant circadian variation in their spontaneous firing rate and resting membrane potential. However, in recordings of MHb neurones from mice lacking the core molecular circadian clock, these temporal differences in MHb activity were absent, indicating that circadian clock signals actively regulate the timing of MHb neuronal states. These observations add to the extracellularly recorded rhythms seen in other brain areas and establish that circadian mechanisms can influence the membrane properties of neurones in extra-SCN sites. Collectively, the results of this study indicate that the MHb may

    The seasonal and daily activity of mosquito vectors of pathogens affecting animals and humans were studied in northeastern Italy at a site within the Po River Delta Park. A CDC-CO2 trap and a gravid trap were operated at 2-h intervals for 24 h every 15 d from May to October 2010. Overall, 5,788 mosquitoes comprising six species were collected, namely Culex pipiens L. (75.1% of total), Aedes caspius (Pallas) (15.2%), Aedes vexans (Meigen) (6.9%), Anopheles maculipennis s.l. Meigen (2.6%), Culiseta annulata (Schrank) (0.2%), and Culex modestus Ficalbi (<0.1%). The relative abundance of these species increased from May until the beginning of July and then decreased, disappearing at the beginning of October. The diel host-seeking patterns and oviposition site-seeking patterns were species specific and were differentially affected by the ecological variables recorded at the day and hour of mosquito collection or two weeks before collection. Knowledge of the seasonal and daily host-seeking patterns of mosquitoes highlights the time periods of the day and the seasons of potential exposure for animals and humans to mosquito-borne pathogens, therefore delineating the best time for the application of preventive measures. Furthermore, knowledge of the oviposition site-seeking activity of the mosquitoes optimizes the capture of gravid females, thereby enhancing the likelihood of detecting pathogens.

    Our aim was to test the normality of physical activity patterns and energy expenditures in normal weight and overweight primary school students. Heart rate estimates of total daily energy expenditure (TEE), active energy expenditure (AEE), and activity patterns were made over 3 consecutive school days in healthy middle-class Tunisian children (46 boys, 44 girls, median age (25th-75th) percentile, 9.2 (8.8-9.9) years. Our cross-section included 52 students with a normal body mass index (BMI) and 38 who exceeded age-specific BMI limits. TEE, AEE and overall physical activity level (PAL) were not different between overweight children and those with a normal BMI [median values (25th-75th) 9.20 (8.20-9.84) vs. 8.88 (7.42-9.76) MJ/d; 3.56 (2.59-4.22) vs. 3.85 (2.77-4.78) MJ/d and 1.74 (1.54-2.04) vs. 1.89 (1.66-2.15) respectively]. Physical activity intensities (PAI) were expressed as percentages of the individual’s heart rate reserve (%HRR). The median PAI for the entire day (PAI24) and for the waking part of day (PAIw) were lower in overweight than in normal weight individuals [16.3 (14.2-18.9) vs. 20.6 (17.9-22.3) %HRR, p < 0.001) and 24.8 (21.6-28.9) vs.26.2 (24.5-30.8) %HRR, p < 0.01], respectively. Overweight children allocated more of their day to sedentary pursuits [385 (336-468) vs 297 (235-468) min/d, p < 0.001], and less time to moderate physical activity [381(321-457) vs. 460 (380-534) min/d, p < 0.01]. Nevertheless, because of the greater energy cost of a given task, total and active daily energy expenditure did not differ from those with a normal BMI. Key points The physical activity intensity for the entire day (PAI24) and for the waking part of day (PAIw) were lower in overweight than in normal weight individuals. However, because the energy cost of activity is greater in those who are overweight, they do not differ in total energy expenditure or in active energy expenditure. Normal children spend more time in moderate activity and less time in

    Nonexercise activities (NAs) are common types of physical activity in daily life and critical component in energy expenditure. However, energetic assessment of NA, particularly in free-living subjects, is a technical challenge. In this study, mechanical modeling and portable device were used to evaluate five common types of NA in daily life: sit to stand, lie to sit, bowing while standing, squat, and right leg over left. A human indirect calorimeter was used to measure the activity energy expenditure of NA. Mechanical work and mechanical efficiency of NA were calculated for mechanical modeling. Thirty-two male subjects were recruited for the study (20 subjects for the development of models and 12 subjects for evaluation of models). The average (mean ± SD) mechanical work of 5 NAs was 2.31 ± 0.50, 2.88 ± 0.57, 1.75 ± 0.55, 3.96 ± 1.25, and 1.25 ± 0.51 J/kg·m, respectively. The mean mechanical efficiencies of those activities were 22.0 ± 3.3%, 26.5 ± 5.1%, 19.8 ± 3.7%, 24.0 ± 5.5%, and 26.3 ± 5.5%. The activity energy expenditure estimated by the models was not significantly different from the measurements by the calorimeter (p > 0.05) with accuracies of 102.2 ± 20.7%, 103.7 ± 25.8%, 105.6 ± 14.6%, 101.1 ± 28.0%, and 95.8 ± 20.7%, respectively, for those activities. These findings suggest that the mechanical models combined with a portable device can provide an alternative method for the energetic analysis of nonexercise activities under free-living condition.

The activity energy expenditure estimated by the models was not significantly different from the measurements by the calorimeter (p > 0.05) with accuracies of 102.2 ± 20.7%, 103.7 ± 25.8%, 105.6 ± 14.6%, 101.1 ± 28.0%, and 95.8 ± 20.7%, respectively, for those activities. These findings suggest that the mechanical models combined with a portable device can provide an alternative method for the energetic analysis of nonexercise activities under free-living condition.

    This study describes the daily activity in a simulated high tide situation of four species of hermit crabs (Pagurus criniticornis, Clibanarius antillensis, C. sclopetarius, and C. vittatus) that coexist in an intertidal flat in southeastern Brazil. Observations were done in two-hour intervals during two subsequent days (48 h) in three replicate pools with thirty crabs each. Among species (between and within genera) there was an evident variation in activity patterns, of which three could be distinguished. The circadian activity patterns of C. antillensis and C. vittatus could be characterized as evening and nocturnal, with resting peaks during the morning and afternoon. The circadian activity pattern of C. sclopetarius was characterized by two marked peaks of inactivity, corresponding to dawn and evening, which could represent an intrinsic association with the semi-lunar tidal cycles of the study area. Pagurus criniticornis showed high activity not influenced by day/night conditions during the entire observed period. These activity pattern variations of the studied hermit crabs should be taken into account in designing further experiments. More precise and accurate interspecific behavioral comparisons among species could be achieved in nocturnal experiments, the high activity period of all species.

    The aim of the present study was to examine the relationship between objective data of physical activity and markers of oxidative stress in older men and women. Participants were old adults, aged≥60years (61 women and 34 men) who were all capable of performing basic daily activities by themselves and lived on their own. To describe physical activity we used objective data measured by accelerometers which record active and sedentary periods during everyday life for five days. Determination of oxidative stress was conducted from three perspectives: determination plasma total antioxidant status (TAS), plasma antioxidant enzyme activities, i.e., glutathione peroxidase (GPx), catalase (CAT) and superoxide dismutase (SOD), and membrane lipid peroxidation (TBARS). In the group of women, those who met physical activity recommendations (WR) had lower level of TAS. In addition, the moderate to vigorous physical activity (MVPA) was negatively correlated with TAS. Simultaneously, MVPA was correlated with increase in the GPx antioxidant enzyme activity, and the counts per minute were positively correlated with CAT activity. In the group of men, the cpm and the MVPA were negatively correlated with lipid peroxidation while lifestyle physical activity was positively correlated with CAT activity. These findings suggest that MVPA in the elderly although it is related to a decrease in the TAS in women, induces adaptive increase in antioxidant enzyme activity and decreases lipid peroxidation in both women and men. These results suggest that at this time of life, it is not only the amount of physical activity performed that is important but also its intensity.

    Text-telephone technology (TTY) has been used for communication between deaf people since 1964. There is a gap in the scientific knowledge about the influence this may have had especially in relation to effective participation in society as well as the feeling of capability, confidence and collective meaningfulness. The aim of the present paper is, first, to disentangle the different aspects of TTY as an empowering artifact; and, second, to explore the role of TTY in their lives. To provide a framework for the empirical analysis, the paper draws on Empowerment Theory: personal control, a proactive approach to life, and a critical awareness of one's socio-political environment. Twenty-four people aged 16-64 with Swedish Sign Language (SSL) as their first language were interviewed. The findings indicate that the introduction of the TTY was of great importance for self-esteem, equality and independence. The findings show that feelings of empowerment are closely linked to language use and contextually driven, and it is in interaction between deaf and hearing that such feelings arise (or not). The results indicate the need for further research into Deaf people's use of other means of interacting, using modern technique for example in social digital media and interactive platforms.

    Objective To explore the factor structure of the Kessler Foundation Neglect Assessment Process (KF-NAP), and evaluate the prevalence and clinical significance of spatial neglect among stroke survivors. Design Inception cohort. Setting Inpatient rehabilitation facility (IRF). Participants 121 participants with unilateral brain damage from their first stroke were assessed within 72 hours of admission to an IRF, and 108 were assessed again within 72 hours before IRF discharge. Interventions Usual and standard IRF care. Main Outcome Measures During each assessment session, occupational therapists measured patients’ functions with the KF-NAP, Functional Independence Measure (FIM™) and Barthel Index (BI). Results The KF-NAP showed excellent internal consistency with a single-factor structure. The exploratory factor analysis revealed the KF-NAP to be unique from both the FIM and BI even though all three scales were correlated. 67.8% of the participants at admission and 47.2% at discharge presented with symptoms of spatial neglect (KF-NAP > 0). Participants showing the disorder at IRF admission were hospitalized longer than those showing no symptoms. Among those presenting with symptoms, the regression analysis showed that the KF-NAP scores at admission negatively predicted FIM scores at discharge, after controlling for age, FIM at admission, and length of stay. Conclusions The KF-NAP uniquely quantifies symptoms of spatial neglect by measuring functional difficulties that are not captured by the FIM or BI. Using the KF-NAP to measure spatial neglect, we found the disorder persistent after inpatient rehabilitation, and replicated previous findings showing that spatial neglect adversely affects rehabilitation outcome even after prolonged IRF care.

    Introduccion. El concepto de reserva cognitiva ha ido ganando interes en la medida en que se ha acumulado evidencia sobre su relacion con la resistencia del cerebro a declinar en su funcionamiento ante amenazas o alteraciones neurologicas. Aunque se ha estudiado en un gran numero de alteraciones (degenerativas, traumaticas, psicopatologicas), pocos trabajos relacionan la reserva cognitiva con la adiccion a sustancias, un proceso multidimensional con clara base neurologica. Objetivo. Explorar la reserva cognitiva de pacientes en tratamiento por adiccion a drogas, relacionandolo con su rendimiento cognitivo en pruebas neuropsicologicas y en actividades de la vida diaria. Pacientes y metodos. Muestra de 57 pacientes en tratamiento por adiccion a sustancias en un centro especifico. Se administraron el cuestionario de reserva cognitiva, la evaluacion cognitiva de Montreal y el inventario de sintomas prefrontales, y se recogieron variables relacionadas con la adiccion. Resultados. Se encontro una relacion positiva entre la reserva cognitiva y el tiempo de abstinencia, y negativa con la gravedad de la adiccion. Aparecieron diferencias significativas segun la reserva cognitiva en rendimiento neuropsicologico (especialmente en ciertos dominios cognitivos) y en actividades cotidianas. Conclusiones. La reserva cognitiva aparece como una variable relacionada con la adiccion y los deficits cognitivos que la acompañan; resulta ser una potencial diana de las actividades rehabilitadoras, vinculada al paradigma de enriquecimiento ambiental, como estrategia para potenciar la resistencia frente al deterioro cognitivo que favorece y mantiene la adiccion y para disminuir el potencial reforzador de la conducta de consumo.

    Despite significant advances in scaffold design, manufacture, and development, it remains unclear what forces these scaffolds must withstand when implanted into the heavily loaded environment of the knee joint. The objective of this study was to fully quantify the dynamic contact mechanics across the tibial plateau of the human knee joint during gait and stair climbing. Our model consisted of a modified Stanmore knee simulator (to apply multi-directional dynamic forces), a two-camera motion capture system (to record joint kinematics), an electronic sensor (to record contact stresses on the tibial plateau), and a suite of post-processing algorithms. During gait, peak contact stresses on the medial plateau occurred in areas of cartilage-cartilage contact; while during stair climb, peak contact stresses were located in the posterior aspect of the plateau, under the meniscus. On the lateral plateau, during gait and in early stair-climb, peak contact stresses occurred under the meniscus, while in late stair-climb, peak contact stresses were experienced in the zone of cartilage-cartilage contact. At 45% of the gait cycle, and 20% and 48% of the stair-climb cycle, peak stresses were simultaneously experienced on both the medial and lateral compartment, suggesting that these phases of loading warrant particular consideration in any simulation intended to evaluate scaffold performance. Our study suggests that in order to design a scaffold capable of restoring ‘normal’ contact mechanics to the injured knees, the mechanics of the intended site of implantation should be taken into account in any pre-clinical testing regime.

    1. Twenty apparently healthy and normal Nigerian male students, resident at the University of Ibadan campus, were studied for seven consecutive days to assess their food energy intake and expenditure and pattern of their daily activities. 2. The mean age (years) of the group was 24.0 (SD 3.23, range 20-30), mean height (m) 1.71 (SD 0.06, range 1.61-1.84) and body-weight (kg) was 61.1 (SD 5.01, range 51.0-69.5). 3. The food intake of each subject was obtained by direct weighing and its energy value determined using a ballistic bomb calorimeter. Patterns of daily activities were recorded and the energy costs of representative activities were determined by indirect calorimetry. 4. Activities mainly involved sitting, mean 580 (SD 167, range 394-732) min/d. Sleeping and standing activities took a mean of 445 (SD 112) and 115 (SD 75) min/d respectively. Personal domestic activities took a mean of 94 (SD 40) min/d. 5. The mean energy intake of the group was 11,182 (SD 1970) kJ/d or 183 (SD 32) kJ/kg body-weight per d. This value is lower than the 12.5 MJ/d recommended by the Food and Agriculture Organization (FAO)/World Health Organization (WHO) (1973) as the energy requirement for an adult man engaged in moderate activities, but it is higher than the FAO/WHO/United Nations University (UNU) (1985) recommended value of 10.8 MJ/d for a male office clerk (light activity). It is also lower than the recommended energy requirement of 11.6 MJ/d for a subsistence farmer (moderately active work) (FAO/WHO/UNU, 1985). 6. The mean energy expenditure of the male subjects was 9876 (SD 1064, range 7159-12,259) kJ/d and was lower than mean intake. 7. The energy intake and expenditure values indicated that the groups participating in the present study were not physically very active. It is an indication that the Nigerian male students expended less but probably consumed more energy than required. It is suggested for health reasons and for mental fitness that the Nigerian male students

    Background. Many older adults know about the health benefits of an active lifestyle, but, frequently, pain prevents them from engaging in physical activity. The majority of older adults experience pain, a complex experience that can vary across time and is shaped by sociocultural factors like gender. Objectives. To describe the time-varying associations between daily pain and physical activity and to explore differences in these associations between women and men. Methods. One hundred and twenty-eight community-dwelling older adults aged 65 years and older were asked to report their pain levels three times daily over a 10-day period and wear an accelerometer to objectively capture their daily physical activity (step counts and minutes of moderate to vigorous physical activity). Results. Increased daily step counts and minutes of moderate to vigorous physical activity were associated with increased daily pain, especially among women. Confirming past literature and contrasting findings for daily pain reports, overall pain levels across the study period were negatively associated with minutes of moderate to vigorous physical activity. Conclusions. Findings highlight that pain is significantly associated with physical activity in old age. The nature of this association depends on the time scale that is considered and differs between women and men. PMID:27445599

    Living with chronic heart failure (CHF) often involves lifelong contact with health care, more or less frequently, depending on fluctuating health-generating disruptions in everyday life. To reduce the influence on continuity in life, health-care professionals should preferably focus on supporting patients in managing their daily lives, based on their perspective. The aim of this study was to describe how the interaction in health-care encounters contributes to either continuity or discontinuity in the daily life for persons with CHF. Interviews with 18 participants were carried out, using the grounded theory method, through data collection and analysis. Two core concepts were constructed from data which reveal a model that illuminates the characteristics of the encounters, the actions of health-care professionals and the normative discourse. Patient-centred agenda consists of the categories: “Experiencing a subordinate approach,” “Objectifying during the encounter” and “Expected to be compliant.” This describes how health-care professionals enhance discontinuity in daily life by using a paternalistic approach in the encounter. Person-centred agenda consists of the categories: “Experiencing an empowering approach,” “Person-centredness during the encounter” and “Expected to be capable.” It describes how participants perceive that health-care professionals enable them to deal with everyday life which enhances continuity. The findings highlight the importance of health-care professionals’ attitudes and communication in encounters with patients. Health care must be designed to support and promote patients’ own strategic thinking by strengthening their self-image to enhance continuity in everyday life. The experience of discontinuity is based on the prevailing health-care culture which focuses on disease and medical treatment and regards it as superior to the illness experience in an everyday life context. We therefore strongly suggest a

    Unobtrusive monitoring of the cardio-respiratory and daily activity for wheelchair users became nowadays an important challenge, considering population aging phenomena and the increasing of the elderly with chronic diseases that affect their motion capabilities. This work reports the utilization of FMCW (frequency modulated continuous wave) Doppler radar sensors embedded in a manual wheelchair to measure the cardiac and respiratory activities and the physical activity of the wheelchair user. Another radar sensor is included in the system in order to quantify the motor activity through the wheelchair traveled distance, when the user performs the manual operation of the wheelchair. A conditioning circuit including active filters and a microcontroller based primary processing module was designed and implemented to deliver the information through Bluetooth communication protocol to an Android OS tablet computer. The main capabilities of the software developed using Android SDK and Java were the signal processing of Doppler radar measurement channel signals, graphical user interface, data storage and Wi-Fi data synchronization with remote physiological and physical activity database.

    Background Exercise stimulates bone remodeling and improves insulin sensitivity (Si), even without associated weight loss. Osteocalcin (OCN), a bone-derived protein, is associated with improved Si. Purpose We examined how daily physical activity is associated with OCN and Si. Methods Physical activity was measured through questionnaires completed in Minneapolis from 2010 to 2012. A physical activity score (PAQsum) was calculated to quantify physical activity (range 1–5). OCN and bone specific alkaline phosphatase (BAP) were measured by ELISA. Si was measured by the insulin modified frequently sampled IV glucose tolerance test. Results The mean PAQsum value was 2.4 ± 0.8 in 47 participants (12–17.9 years old). PAQsum was positively associated with OCN (p = 0.006). Participants with PAQsum <  2 had significantly lower OCN levels compared to participants with PAQsum >  2 (p < 0.02). Obesity did not modify the association between PAQsum and OCN. There was no statistically significant association between PAQsum and Si or between OCN and Si, even after adjustment for percent body fat. Conclusions OCN is higher in more physically active individuals. More research is needed to clarify the relationship between OCN, physical activity and Si. PMID:26236583

    Phenomenological responses of plants to daily short-term exposure to low hardening temperature was studied under chamber and field conditions. Experiments were carried out on cucumber (Cucumis sativus L.), barley (Hordeum vulgare L.), marigolds (Tagetes L.), and petunia (Petunia x hybrida) plants. The obtained data demonstrated a similar pattern of response in all studied plant species to different variants of exposure to low hardening temperature. The main features of plant response to daily short-term exposure to low hardening temperature include: a higher rate of increase in cold tolerance (cf. two- or threefold increase relative to constant low hardening temperature) that peaked on day 5 (cf. day 2 at constant low hardening temperature) and was maintained for 2 weeks (cf. 3-4 days at constant low hardening temperature); a simultaneous increase in heat tolerance (cf. twofold relative to constant low hardening temperature) maintained over a long period (cf. only in the beginning of the exposure to constant low hardening temperature); a sharp drop in the subsequent cold tolerance after plant incubation in the dark (cf. a very low decrease in cold tolerance following the exposure to constant low hardening temperature); a combination of high cold tolerance and high photochemical activity of the photosynthetic apparatus (cf. a low non-photochemical quenching at constant low hardening temperature); and the capacity to rapidly increase cold tolerance in response to repeated short-term exposures to low hardening temperature in plants grown outdoors (cf. a gradual increase after repeated exposure to constant low hardening temperature). Possible methods underlying the plant response to daily short-term exposure to low temperature are proposed.

    Physical activity is usually considered as an important component of a healthy lifestyle, including a preventive effect on the risk of falls in the elderly. The relationship between physical activity and falls is complex: physical activity is a prerequisite to maintain neuromuscular functioning, necessary to keep balance and to react to a fall, but a higher level of physical activity also implies a greater exposure to environmental threats, possibly leading to a fall. Related to this greater exposure to threats, the use of a walking aid may protect against falls in those who have impaired mobility. In this cross-sectional study we investigated the relationship between daily physical activity and falls and the use of a walking aid in elderly subjects. Participants were 131 men and 563 women, aged 70 years and over (mean age and standard deviation: 82+/-6 years), living in homes for the elderly (n=335) and apartment houses for elderly (n=359). Data on baseline characteristics and falls in the previous year were obtained using a questionnaire. The level of daily physical activity in the previous year was obtained by means of a questionnaire regarding household and leisure activities. Subjects with a lower extremity fracture in the previous year were excluded from the analyses. Data were analysed using multiple logistic regression, adjusted for age, gender, and residence. In the past year, 40% of the participants fell at least one time, and 19% of the participants fell two times or more. Since falls and recurrent falls were nonlinearly related to the level of daily physical activity, the physical activity score was grouped into quartiles: the highest quartile corresponding to the highest activity level. Odds ratios (and 95% confidence intervals) for falls and recurrent falls for subjects in the highest quartile contrasted with those in the lowest quartile were 0.5 (0.3-0.9) and 0.3 (0.2-0.6), respectively. The risk of falls and recurrent falls was not lower for those

    Animal ecology is shaped by energy costs, yet it is difficult to measure fine-scale energy expenditure in the wild. Because metabolism is often closely correlated with mechanical work, accelerometers have the potential to provide detailed information on energy expenditure of wild animals over fine temporal scales. Nonetheless, accelerometry needs to be validated on wild animals, especially across different locomotory modes. We merged data collected on 20 thick-billed murres (Uria lomvia) from miniature accelerometers with measurements of daily energy expenditure over 24 h using doubly labelled water. Across three different locomotory modes (swimming, flying and movement on land), dynamic body acceleration was a good predictor of daily energy expenditure as measured independently by doubly labelled water (R(2) = 0.73). The most parsimonious model suggested that different equations were needed to predict energy expenditure from accelerometry for flying than for surface swimming or activity on land (R(2) = 0.81). Our results demonstrate that accelerometers can provide an accurate integrated measure of energy expenditure in wild animals using many different locomotory modes. PMID:23256182

    We have previously shown that muscle metabolic function measured during exercise is related to exercise performance and subsequent 1-yr weight gain. Because it is well established that physical activity is important in weight maintenance, we examined muscle function relationships with free-living energy expenditure and physical activity. Subjects were 71 premenopausal black and white women. Muscle metabolism was evaluated by (31)P magnetic resonance spectroscopy during 90-s isometric plantar flexion contractions (45% maximum). Free-living energy expenditure (TEE) was measured using doubly labeled water, activity-related energy expenditure (AEE) was calculated as 0.9 x TEE - sleeping energy expenditure from room calorimetry, and free-living physical activity (ARTE) was calculated by dividing AEE by energy cost of standard physical activities. At the end of exercise, anaerobic glycolytic rate (ANGLY) and muscle concentration of phosphomonoesters (PME) were negatively related to TEE, AEE, and ARTE (P < 0.05). Multiple regression analysis showed that both PME (partial r = -0.29, <0.02) and ANGLY (partial r = -0.24, P < 0.04) were independently related to ARTE. PME, primarily glucose-6-phosphate and fructose-6-phosphate, was significantly related to ratings of perceived exertion (r = 0.21, P < or = 0.05) during a maximal treadmill test. PME was not related to ARTE after inclusion of RPE in the multiple regression model, suggesting that PME may be obtaining its relationship with ARTE through an increased perception of effort during physical activity. In conclusion, physically inactive individuals tend to be more dependent on anaerobic glycolysis during exercise while relying on a glycolytic pathway that may not be functioning optimally.

    At the 67th Gerontological Society of America Annual Meeting, a preconference workshop was convened to discuss the challenges of accurately assessing physical activity in older populations. The advent of wearable technology (eg, accelerometers) to monitor physical activity has created unprecedented opportunities to observe, quantify, and define physical activity in the real-world setting. These devices enable researchers to better understand the associations of physical activity with aging, and subsequent health outcomes. However, a consensus on proper methodological use of these devices in older populations has not been established. To date, much of the validation research regarding device type, placement, and data interpretation has been performed in younger, healthier populations, and translation of these methods to older populations remains problematic. A better understanding of these devices, their measurement properties, and the data generated is imperative to furthering our understanding of daily physical activity, its effects on the aging process, and vice versa. The purpose of this article is to provide an overview of the highlights of the preconference workshop, including properties of the different types of accelerometers, the methodological challenges of employing accelerometers in older study populations, a brief summary of ongoing aging-related research projects that utilize different types of accelerometers, and recommendations for future research directions.

    The authors investigated the general activity and nest occupation patterns of fox squirrels in a natural setting using temperature-sensitive data loggers that measure activity as changes in the microenvironment of the animal. Data were obtained from 25 distinct preparations, upon 14 unique squirrels, totaling 1385 recording days. The animals were clearly diurnal, with a predominantly unimodal activity pattern, although individual squirrels occasionally exhibited bimodal patterns, particularly in the spring and summer. Even during the short days of winter (9 hours of light), the squirrels typically left the nest after dawn and returned before dusk, spending only about 7 hours out of the nest each day. Although the duration of the daily active phase did not change with the seasons, the squirrels exited the nest earlier in the day when the days became longer in the summer and exited the nest later in the day when the days became shorter in the winter, thus tracking dawn along the seasons. During the few hours spent outside the nest each day, fox squirrels seemed to spend most of the time sitting or lying. These findings suggest that fox squirrels may have adopted a slow life history strategy that involves long periods of rest on trees and short periods of ground activity each day. PMID:26963918

    I will present our recent work on the organization of signaling molecules on the surface of living cells. Using novel experimental and theoretical approaches we have found that many cell surface receptors are organized as dynamic clusters driven by active currents and stresses generated by the cortical cytoskeleton adjoining the cell surface. We have shown that this organization is optimal for both information processing and computation. In connecting active mechanics in the cell with information processing and computation, we bring together two of the seminal works of Alan Turing.

    High temporal resolution information on burned area is a prerequisite for incorporating bottom-up estimates of wildland fire emissions in regional air transport models and for improving models of fire behavior. We used the Moderate Resolution Imaging Spectroradiometer (MODIS) active fire product (MO(Y)D14) as input to a kriging interpolation to derive continuous maps of the evolution of nine large wildland fires. For each fire, local input parameters for the kriging model were defined using variogram analysis. The accuracy of the kriging model was assessed using high resolution daily fire perimeter data available from the U.S. Forest Service. We also assessed the temporal reporting accuracy of the MODIS burned area products (MCD45A1 and MCD64A1). Averaged over the nine fires, the kriging method correctly mapped 73% of the pixels within the accuracy of a single day, compared to 33% for MCD45A1 and 53% for MCD64A1.

    Although wearable accelerometers can successfully recognize activities and detect falls, their adoption in real life is low because users do not want to wear additional devices. A possible solution is an accelerometer inside a wrist device/smartwatch. However, wrist placement might perform poorly in terms of accuracy due to frequent random movements of the hand. In this paper we perform a thorough, large-scale evaluation of methods for activity recognition and fall detection on four datasets. On the first two we showed that the left wrist performs better compared to the dominant right one, and also better compared to the elbow and the chest, but worse compared to the ankle, knee and belt. On the third (Opportunity) dataset, our method outperformed the related work, indicating that our feature-preprocessing creates better input data. And finally, on a real-life unlabeled dataset the recognized activities captured the subject's daily rhythm and activities. Our fall-detection method detected all of the fast falls and minimized the false positives, achieving 85% accuracy on the first dataset. Because the other datasets did not contain fall events, only false positives were evaluated, resulting in 9 for the second, 1 for the third and 15 for the real-life dataset (57 days data).

    In this study, we designed a new tent trap; the BioDiVector (BDV) tent trap, consisting of two rectangular tents that use human bait without endangering the technical personnel. The daily activity pattern of Aedes aegypti and Aedes albopictus in intra, peri, and extradomiciliary sites was studied in an endemic area of dengue in southern Mexico by using the BDV tent trap. Totals of 3,128 individuals of Ae. aegypti and 833 Ae. albopictus were captured. More Ae. aegypti males than females were caught, while the opposite was true with Ae. albopictus. The activity of both mosquito species was affected by the interaction between the collection site and time of day. In general, more individuals of both mosquito species were captured at the extradomicillary sites than at the peri and intradomicillary sites. Mosquitoes showed two peaks of activity, one in the morning and the other in the afternoon, but in general this only occurred at the extradomicillary sites, whereas no peak of activity was observed at the intra and peridomicillary sites. Overall, Ae. aegypti had a higher indirect biting rate than Ae. albopictus. Finally, due to its efficiency, simplicity, and low cost, we suggest the use of this innovative tool for entomological surveillance, bionomics and vector incrimination studies in geographical areas where dengue and other arboviruses are present.

    Transient hypotension may be one of many factors contributing to the high prevalence of falls among elderly people. To determine the frequency and magnitude of hypotensive responses to common daily activities, and their potential relationship to falls in the elderly, we examined blood pressure (BP) and heart rate during a standardized series of activities in 38 institutionalized recurrent fallers (age, 87 +/- 6 years), 20 institutionalized nonfallers (age, 85 +/- 5 years), and 10 healthy young control subjects (age, 24 +/- 3 years). The coefficient of variation for systolic BP during all activities was higher in elderly subjects (fallers, 14% +/- 5%; nonfallers, 12% +/- 3%) than in young control subjects (8% +/- 1%). In contrast, the coefficient of variation for heart rate during all activities was higher in young subjects than in the elderly subjects. Elderly subjects had marked BP reduction following meals and nitroglycerin, which was significantly greater in fallers than in nonfallers, independent of the cause of the fall. Thus, institutionalized elderly have marked BP variability and hypotensive responses to meals and nitroglycerin. A decline in BP during common preload-reducing stresses may predispose some elderly people to falls.

    The purpose of this program was to assess the problems posed to reactor decommissioning by long-lived activation products in reactor construction materials. Samples of stainless steel, vessel steel, concrete, and concrete ingredients were analyzed for up to 52 elements in order to develop a data base of activatable major, minor, and trace elements. Large compositional variations were noted for some elements. Cobalt and niobium concentrations in stainless steel, for example, were found to vary by more than an order of magnitude. A thorough evaluation was made of all possible nuclear reactions that could lead to long lived activation products. It was concluded that all major activation products have been satisfactorily accounted for in decommissioning planning studies completed to date. A detailed series of calculations was carried out using average values of the measured compositions of the appropriate materials to predict the levels of activation products expected in reactor internals, vessel walls, and bioshield materials for PWR and BWR geometries. A comparison is made between calculated activation levels and regulatory guidelines for shallow land disposal according to 10 CFR 61. This analysis shows that PWR and BWR shroud material exceeds the Class C limits and is, therefore, generally unsuitable for near-surface disposal. The PWR core barrel material approaches the Class C limits. Most of the remaining massive components qualify as either Class A or B waste with the bioshield clearly Class A, even at the highest point of activation. Selected samples of activated steel and concrete were subjected to a limited radiochemical analysis program as a verification of the computer model. Reasonably good agreement with the calculations was obtained where comparison was possible. In particular, the presence of /sup 94/Nb in activated stainless steel at or somewhat above expected levels was confirmed.

    Objective: To determine whether the level of physical activity in daily life (PADL) is associated with pulmonary function in adult smokers. Methods: We selected 62 adult smokers from among the participants of an epidemiological study conducted in the city of Santos, Brazil. The subjects underwent forced spirometry for pulmonary function assessment. The level of PADL was assessed by the International Physical Activity Questionnaire and triaxial accelerometry, the device being used for seven days. The minimum level of PADL, in terms of quantity and intensity, was defined as 150 min/week of moderate to vigorous physical activity. Correlations between the studied variables were tested with Pearson's or Spearman's correlation coefficient, depending on the distribution of the variables. We used linear multiple regression in order to analyze the influence of PADL on the spirometric variables. The level of significance was set at 5%. Results: Evaluating all predictors, corrected for confounding factors, and using pulmonary function data as outcome variables, we found no significant associations between physical inactivity, as determined by accelerometry, and spirometric indices. The values for FVC were lower among the participants with arterial hypertension, and FEV1/FVC ratios were lower among those with diabetes mellitus. Obese participants and those with dyslipidemia presented with lower values for FVC and FEV1. Conclusions: Our results suggest that there is no consistent association between physical inactivity and pulmonary function in adult smokers. Smoking history should be given special attention in COPD prevention strategies, as should cardiovascular and metabolic comorbidities. PMID:27167434

    Hepatic P450 monooxygenase activities, assessed by measurement of 7-alkoxycoumarin O-dealkylase (ACD) activities, show obvious daily fluctuations in male rats with high values during the dark period and low values during the light period. We have already confirmed that the ACD activities are controlled by the suprachiasmatic nucleus (SCN), which is well known as the oscillator of circadian rhythm. Recently, it is reported that circadian oscillators exist not only in the SCN but also in peripheral organs. To date, it is unclear which circadian oscillators predominantly drive the daily fluctuations of hepatic ACD activities. To address this question, we examined the effects of restricted feeding, which uncouples the circadian oscillators in the liver from the central pacemaker in the SCN, on the daily fluctuations in hepatic ACD activities in male rats. Here we show that restricted feeding inverts the oscillation phase of the daily fluctuations in hepatic ACD activities. Regarding the hepatic P450 content, there were no fluctuations between the light and dark periods under ad libitum and restricted feeding conditions. Therefore, it is considered that the daily fluctuations in hepatic ACD activities are predominantly driven by the circadian factors in peripheral organs rather than by the oscillator in the SCN directly.

    Background: The aim of this study was to explore the population-wide distribution in the practice of leisure-time physical activity among Canadian youth and how physical activity level is influenced by contextual features of the environment. Methods: We studied the self-reported leisure-time physical activity of 54 832 Canadians aged 12 to 17 years. Observations were structured according to a 4-level geographic hierarchy. The outcome studied was a dichotomous indicator that referred to achieving (or not) the recommended daily level of leisure-time physical activity. To investigate the influence of the contextual features, we conducted multilevel logistic regressions. Results: For both girls and boys, significant variations were observed between health regions and between neighbourhoods within the provinces. Girls who lived in an urban setting showed lower odds of achieving the recommended physical activity level, as did those surveyed during the winter. Boys surveyed during the winter also showed lower odds of achieving the recommended level, but living in an urban setting had no effect on activity levels. Analysis of province-level residuals showed that girls living in Quebec were less likely to achieve the recommended activity level as compared with the national mean, and girls living in Ontario and British Columbia were more likely to achieve that threshold. Boys living in Ontario were more likely to achieve the recommended activity level as compared with the national mean. Youth had up to a 17% increased chance of achieving the recommended physical activity level if they lived in a context with a higher activity achievement level. Interpretation: Leisure-time physical activity was associated with environmental factors at multiple geographic scales among Canadian youth. The variation was more important at the neighbourhood level. The results provide rationale for further investigation into how leisure-time physical activity is promoted in different contexts

    The aim of this report was to present some of our results, in a compressed form, obtained from our previous studies on the effect of 364-d hypokinesia (decreased number of steps taken per day by the volunteers) on the following: (1) regulation of fluid volume and osmosis, (2) regulation of electrolytes, and (3) functional condition of the kidneys and its role in the fluid-electrolyte homeostasis on 30 physically healthy male volunteers aged 22-26 years. Prior to their exposure to hypokinesia all subjects were on 13.8 km/day (10,000 running steps/day) and were all well conditioned, with (oxygen uptake capacities (VO2 max 68 ml/kg-min). During the hypokinetic period of 364 days, the 1st group was subjected to pure hypokinesia (HK), that is without the use of physical exercise (PE), the 2nd group was subjected to a set of intensive PE (energy expenditure of 700 kcal/h) and the 3rd group submitted to a set of moderate PE (energy expenditure of 400 kcal/h). All volunteers consumed daily fluid and salt supplementation (FSS) aimed at increasing body hydration level during the hypokinetic period. For the simulation of the hypokinetic effect all volunteers were kept on 2.7 km/day (3000 walking steps per day). All volunteers were on a diet of freshly prepared food, with a daily intake of 2500-2700 kcal, 3340 ml water, 1500 mgs calcium, 500 mgs magnesium, 1200 mgs potassium, 1500 mgs phosphorus, 8.5 gms sodium and 9.8 gms chloride. The amount of fluid and electrolytes consumed and eliminated in urine, as well as their concentrations in the urine and blood plasma were determined. There were also measured urinary volume, osmolality, creatine, and urea changes in urine. During HK the amount of fluid and electrolytes consumed daily decreased while the rate of excretion increased significantly. During post HK the fluid and electrolytes concentrations in urine decreased significantly. The urinary urea, osmolality and creatinine increased significantly during HK. It was concluded

    Considerable evidence documents linkages between parental knowledge of youth activities and youth risky behavior. We extended this research to determine whether parental knowledge was associated with youth physical health, including reports of physical symptoms (e.g., headaches, stomachaches) and a biomarker of hypothalamic pituitary adrenocortical (HPA) axis functioning (i.e., salivary cortisol levels). Participants were children of employees in the Information Technology division of a Fortune 500 company (N = 132, mean age youth = 13.39 years, 55% female) who participated in a daily diary study. Data were collected via telephone calls on 8 consecutive evenings. On 4 study days, cortisol samples were collected at 4 time points (waking, 30 min after waking, before dinner, bedtime). Multilevel models revealed that, at the between-person level, youth whose parents had higher average knowledge about their activities, exhibited lower bedtime cortisol levels. Furthermore, at the within-person level, on days when parents displayed more knowledge than usual (relative to their own 8-day average), youth had lower before-dinner cortisol than usual. Linkages between average parental knowledge and physical health symptoms were moderated by youth age: Younger but not older adolescents whose parents were more knowledgeable had fewer physical health symptoms, on average. A next step is to identify the processes that underlie these associations. PMID:26751757

    Women have a higher prevalence of fibromyalgia and myofascial pain than men, but sex differences in muscle pain are inconsistently detected. We examined sex differences in ratings and effects of recalled and experimentally-induced muscle pain. In Study 1 (N = 188), participants completed a questionnaire about recalled muscle pain. In Study 2 (N = 55), participants’ described muscle pain from an exercise stimulus across three days by telephone. Muscle pain ratings, self-care behaviors for muscle pain, and effects of muscle pain on activities were measured. No significant sex differences were found except that women tended to view exercise as more effective for decreasing muscle pain than men (F1, 187 = 5.43, p = .02, η2 = .03), fewer women performed exercise for induced muscle pain than men, and women’s activity interference was significantly higher than men’s at the third day post-exercise (F2, 42 = 6.54, p= .01, η2 = .14). These findings support the absence of meaningful sex differences in muscle pain ratings. However, additional investigations are needed that consider the daily activities completed by people and the prevalence and incidence of performing a wide range of self-care behaviors for pain. Perspective: These studies support that sex differences are not present in recalled and experimentally-induced muscle pain ratings. Therefore, we must be cautious about generalizing the musculoskeletal pain literature to muscle pain. Additional research is needed to interpret potential sex differences in self-care behaviors for muscle pain and activity interference from muscle pain. PMID:18088556

    The aim of this study was to investigate genetic relationships between beef traits of station-tested young bulls and carcass and meat quality traits (MQ) of commercial intact males in Piemontese cattle. Phenotypes for daily gain (DG) and live fleshiness traits (width at withers: WW; shoulder muscularity: SM; loin width: LW; loin thickness: LT; thigh muscularity: TM; thigh profile: TP) and thinness of the shin bone (BT) were available for 3,109 and 2,183 performance-tested young bulls, respectively. Carcass daily gain (CDG), carcass conformation (SEUS), pH at 24 h (pH24h) and 8 d after slaughter (pH8d), lightness (L*), redness (a*), yellowness (b*), hue angle (HA), saturation index (SI), drip loss (DL), cooking loss (CL), and shear force (SF) were assessed for 1,208 commercial intact males. (Co) variance components were estimated in a set of twelve 9-traits analyses using REML and linear animal models including all performance-test traits and 1 carcass or MQ trait at a time. Heritabilities ± SE of beef traits ranged from 0.26 ± 0.03 (LW) to 0.47 ± 0.01 (DG), whereas those of carcass traits and MQ from 0.06 ± 0.03 (CL) to 0.63 ± 0.04 (HA). The genetic correlation (rg) between DG and CDG was 0.75 ± 0.10, indicating that DG, as measured at the test station, is a good indicator of the carcass gain achieved by commercial animals under farms conditions. Daily BW gain of station-tested bulls correlated positively with color traits (from 0.11 ± 0.12 to 0.54 ± 0.09), ph8d (rg ± SE = 0.31 ± 0.11), DL (rg ± SE = 0.29 ± 0.17), and CL (rg ± SE = 0.27 ± 0.18). Live fleshiness of station-tested bulls exhibited genetic correlations with MQ of commercial animals that were positive for L* and b* (from 0.13 ± 0.08 to 0.65 ± 0.14) and negative for pH (from -0.27 ± 0.15 to -0.57 ± 0.11), CL (from -0.16 ± 0.23 to -0.43 ± 0.22), and SF (TM: rg ± SE = -0.31 ± 0.15; TP: rg ± SE = -0.41 ± 0.17). The thinness of the shin bone correlated unfavorably with CDG (rg ± SE

    Acute and regular exercise as well as physical activity (PA) is related to well-being and positive affect. Recent studies have shown that even daily, unstructured physical activities increase positive affect. However, the attempt to achieve adherence to PA or exercise in inactive people through public health interventions has often been unsuccessful. Most studies analyzing the activity-affect association in daily life, did not report participants’ habitual activity behavior. Thus, samples included active and inactive people, but they did not necessarily exhibit the same affective reactions to PA in daily life. Therefore the present study investigated whether the association between PA and subsequent affective state in daily life can also be observed in inactive individuals. We conducted a pilot study with 29 inactive university students (mean age 21.3 ± 1.7 years) using the method of ambulatory assessment. Affect was assessed via electronic diary and PA was measured with accelerometers. Participants had to rate affect every 2 h on a six item bipolar scale reflecting the three basic mood dimensions energetic arousal, valence, and calmness. We calculated activity intensity level [mean Metabolic Equivalent (MET) value] and the amount of time spent in light activity over the last 15 min before every diary prompt and conducted within-subject correlations. We did not find significant associations between activity intensity and the three mood dimensions. Due to the high variability in within-subject correlations we conclude that not all inactive people show the same affective reactions to PA in daily life. Analyzing the PA-affect association of inactive people was difficult due to little variance and distribution of the assessed variables. Interactive assessment and randomized controlled trials might help solving these problems. Future studies should examine characteristics of affective responses of inactive people to PA in daily life.

    Hybrid interfaces between organic semiconductors and living tissues represent a new tool for in-vitro and in-vivo applications. In particular, conjugated polymers display several optimal properties as substrates for biological systems, such as good biocompatibility, excellent mechanical properties, cheap and easy processing technology, and possibility of deposition on light, thin and flexible substrates. These materials have been employed for cellular interfaces like neural probes, transistors for excitation and recording of neural activity, biosensors and actuators for drug release. Recent experiments have also demonstrated the possibility to use conjugated polymers for all-optical modulation of the electrical activity of cells. Several in-vitro study cases have been reported, including primary neuronal networks, astrocytes and secondary line cells. Moreover, signal photo-transduction mediated by organic polymers has been shown to restore light sensitivity in degenerated retinas, suggesting that these devices may be used for artificial retinal prosthesis in the future. All in all, light sensitive conjugated polymers represent a new approach for optical modulation of cellular activity. In this work, all the steps required to fabricate a bio-polymer interface for optical excitation of living cells are described. The function of the active interface is to transduce the light stimulus into a modulation of the cell membrane potential. As a study case, useful for in-vitro studies, a polythiophene thin film is used as the functional, light absorbing layer, and Human Embryonic Kidney (HEK-293) cells are employed as the biological component of the interface. Practical examples of successful control of the cell membrane potential upon stimulation with light pulses of different duration are provided.

    BACKGROUND Children of workers exposed to pesticides are at risk of secondary pesticide exposure. We evaluated the potential for lower acetylcholinesterase activity in children cohabiting with fresh-cut flower plantation workers, which would be expected from organophosphate and carbamate insecticide exposure. Parental home surveys were performed and acetylcholinesterase activity was measured in 277 children aged 4–9 years in the study of Secondary Exposure to Pesticides among Infants, Children and Adolescents (ESPINA). Participants lived in a rural county in Ecuador with substantial flower plantation activity. RESULTS Mean acetylcholinesterase activity was 3.14 U/ml, standard deviation (SD): 0.49. It was lower by 0.09 U/ml (95% confidence interval (CI) −0.19, −0.001) in children of flower workers (57% of participants) than non-flower workers’ children, after adjustment for gender, age, height-for-age, hemoglobin concentration, income, pesticide use within household lot, pesticide use by contiguous neighbors, examination date and residence distance to nearest flower plantation. Using a 4 level polychotomous acetylcholinesterase activity dependent variable, flower worker cohabitation (vs. not) had odds ratio 3.39 (95% CI 1.19, 9.64) for being <15th percentile compared to the highest tertile. Children cohabitating for ≥5 years (vs. never) had OR of 4.11 (95% CI: 1.17, 14.38) of AChE activity within <15th percentile compared to the highest tertile. CONCLUSIONS Cohabitation with a flower worker was related to lower acetylcholinesterase activity in children. This supports the hypothesis that the amount of take-home pesticides from flower workers suffices to decrease acetylcholinesterase activity, with lower activity associated with longer exposure.

    The purpose of this study was to examine relationships between weather and outdoor physical activity (PA). An online weather source was used to obtain daily max temperature [DMT], precipitation, and wind speed. An infra-red trail counter provided data on daily trail use along a greenway, over a 2-year period. Multiple regression analysis was used to examine associations between PA and weather, while controlling for day of the week and month of the year. The overall regression model explained 77.0% of the variance in daily PA (p < 0.001). DMT (b = 10.5), max temp-squared (b = −4.0), precipitation (b = −70.0), and max wind speed (b = 1.9) contributed significantly. Conclusion: Aggregated daily data can detect relationships between weather and outdoor PA. PMID:21556205

    Associations between perimenstrual physical and psychological symptoms have not been adequately studied among adolescent girls. The purpose of the present study was to test a mediation hypothesis postulating that perimenstrual disengagement from daily activities would mediate the association between physical symptoms and psychological symptoms. A non-clinical sample of N = 208 Italian adolescent girls (age M = 16.68 years) completed a 95-item online retrospective questionnaire regarding perimenstrual symptoms, and how these symptoms affect their daily activities. Structural Equation Modeling was used to test the mediation hypothesis. Results showed that physical and psychological symptoms were strongly associated. More importantly, results supported the hypothesis that perimenstrual disengagement from daily activities mediates the association between physical symptoms and psychological symptoms, but only for depressed mood and cognitive symptoms. This study provides support for a novel theoretical framework linking diverse aspects of menstrual cycle change. Longitudinal research is needed to replicate these findings.

    Activity-based sensors for rate adaptive pacing have been available for several years and now include several different types: vibration; acceleration; gravitation; and movement. However, a systematic comparison evaluating the relative advantages and disadvantages of these various sensors has received little study. The purpose of the present study was to compare these sensor subtypes using treadmill testing and an outdoor test circuit, which simulated daily life activities and included both uphill and downhill walking. Pacemakers were strapped on the chest of healthy volunteers and connected to one channel of an ambulatory recording device, which also recorded the subject's intrinsic heart rate. The pacemakers were programmed using an initial treadmill test to standardize the rate responsive parameters for each device. Nine different pacemaker models were studied including 3 vibration-based (Elite, Synchrony, Metros), 4 acceleration-based (Relay, Excel, Ergos, Trilogy), 1 gravitational-based (Swing), and 1 movement-based (Sensorithm) device. All devices demonstrated a prompt rate response with casual walking on flat ground. The vibration-, gravitational-, and movement-based pacemakers showed a pronounced rate decline during more strenuous work, e.g., walking uphill. This phenomenon was absent in the accelerometer-based units. In particular, the vibration- and movement-based units showed a higher rate with walking downhill compared to uphill. An optimally tuned rate behavior on the treadmill usually did not provide an optimal rate behavior during daily activities and there was a tendency to overstimulation during low workload. The development of the two newest sensors (gravitational and movement) did not result in an improved performance of rate response behavior. Overall, the accelerometer-based pacemakers simulated or paralleled sinus rate behavior the most closely.

    Type 2 diabetes (T2D) and ageing have well documented effects on every organ in the body. In T2D the autonomic nervous system is impaired due to damage to neurons, sensory receptors, synapses and the blood vessels. This paper will concentrate on how autonomic impairment alters normal daily activities. Impairments include the response of the blood vessels to heat, sweating, heat transfer, whole body heating, orthostatic intolerance, balance, and gait. Because diabetes is more prevalent in older individuals, the effects of ageing will be examined. Beginning with endothelial dysfunction, blood vessels have impairment in their ability to vasodilate. With this and synaptic damage, the autonomic nervous system cannot compensate for effectors such as pressure on and heating of the skin. This and reduced ability of the heart to respond to stress, reduces autonomic orthostatic compensation. Diminished sweating causes the skin and core temperature to be high during whole body heating. Impaired orthostatic tolerance, impaired vision and vestibular sensing, causes poor balance and impaired gait. Overall, people with T2D must be made aware and counseled relative to the potential consequence of these impairments. PMID:22566994

    Changes in body composition, in particular the onset of obesity, may result from reductions in total daily energy expenditure (TDEE) as a consequence of relative physical inactivity. Children previously treated for acute lymphoblastic leukemia (ALL) become obese, yet the mechanism remains undefined. TDEE and physical activity levels [PAL = TDEE/basal metabolic rate (BMR)] were measured in 34 long-term survivors of ALL and compared with results from 21 survivors of other malignancies and 32 healthy sibling control subjects using the flex-heart rate technique. Body composition was measured by dual energy x-ray absorptiometry. The median TDEE was reduced in the ALL group (150 kJ x kg d(-1)) compared with other malignancies and controls (207 and 185 kJ x kg d(-1), respectively, p < 0.01). This reduction was accounted for mainly by a relative decrease in the PAL of the ALL group (1.24) compared with both other malignancies and controls (1.58 and 1.47, respectively, p < 0.01). TDEE and PAL were correlated with percentage body fat (r = -0.39, p < 0.001 and r = -0.24, p < 0.05, respectively). Obesity in survivors of ALL may, in part, be explained by a reduction in TDEE as a consequence of reduced PAL. The cause of such reduction is uncertain.

    Singapore, a developed city state of four million people is experiencing the pitfalls that come with rapid modernisation and economic progress- elevated disease risk factors among adults and young people. Weekly compulsory physical education classes of 70 minutes in schools and the associated sports activities after classes are inadequate to meet emergent physical activity guidelines of a daily accumulation of at least 90 minutes of physical activity of at least moderate intensity. Daily play sessions that are exclusive of an active daily recess, physical education classes taught by trained specialists and after-school sport sessions, can provide many developmental and holistic health benefits that may carry over into adulthood. A school environment that is play-encouraging, play-enabling and play-inviting can be a useful, innovative and natural way of inculcating a love for movement and help redress a serious trend of physical activity insufficiency while youngsters engage electronic gaming activities. Pilot initiatives for the PRIDE (personal responsibility in daily effort) for PLAY (participation in lifelong activity for youths) programme is a radicalised approach in a number of primary schools in Singapore to infuse daily physical play of between 20 to 45 minutes during curriculum hours. The hope is that PRIDE for PLAY will reap benefits of improved holistic health of youngsters- better physical, social, emotional and mental attributes. While PRIDE for PLAY is no panacea to all of the ills of modernisation, it will go some way in helping the students of tomorrow to be physically healthy, socially more engaged and tolerant of others
