Objectives Physical activity is recommended for managing chronic health conditions but is rarely maintained. This feasibility study aimed to evaluate the preliminary efficacy of a motivational interviewing and cognitive-behavioural intervention for long-term physical activity for adults with chronic health conditions. Methods Participants ( N = 37) with stable conditions (e.g. diabetes) were randomized into a three-month motivational interviewing and cognitive-behavioural group ( N = 20) or usual care ( N = 17) after completing a physical activity referral scheme. Participants completed physical activity (e.g. average steps per day and kilocalorie expenditure), psychological (e.g. self-efficacy) and epidemiological (e.g. body mass index) standardized measures at baseline, three- and six-month follow-up. Treatment fidelity and feasibility were assessed. Results Thirty-five participants completed the study (96% retention). The motivational interviewing and cognitive-behavioural group maintained kilocalorie expenditure at three ( p = 0.009) and six months ( p = 0.009). Exercise barrier self-efficacy ( p = 0.03), physical ( p = 0.02) and psychological ( p = 0.01) physical activity experiences were increased at three months only. No difference was found for average steps/day, social support, coping skills and epidemiological factors. Discussion This is the first study to demonstrate the feasibility and preliminary efficacy of motivational interviewing and cognitive-behavioural interventions for promoting physical activity maintenance in a clinical population. A large-scale trial with a longer follow-up (≥6 months) is warranted with treatment fidelity assessment.

Introduction Understanding physical activity is key in the fight against childhood obesity. The objective of this study was to examine the feasibility of using certain wearable devices to measure physical activity among children. Methods A qualitative study was conducted with 25 children aged 7 to 10 years to assess acceptability and compliance of wearable activity devices in this age group. During March through August 2012, children participated in a 4-week study of 3 accelerometer models and a heart rate monitor. Children were asked to use a different device each week for 7 consecutive days. Children and their parents completed structured interviews after using each device; they also completed a final exit interview. Results The wrist-worn Polar Active was the device most preferred by children and was associated with the highest level of compliance. Devices that are comfortable to wear, fit properly, have engaging features, and are waterproof increase feasibility and are associated with higher levels of compliance. Conclusion The wrist-worn device was the most feasible for measuring physical activity among children aged 7 to 10 years. These findings will inform researchers in selecting tools for measuring children’s physical activity. PMID:24854236

This feasibility study assessed the effects of an exercise plus group-based self-regulatory skills intervention on obese youths' physical activity, social cognitions, body composition and strength. Forty-three obese youth (male = 13, BMI > 95th percentile; 10-16 yrs) completed this 12-week intervention. Assessments were taken at baseline, week 6, 13 and 12 weeks post-intervention (week 24). Although no attention control group (i.e. exercise only) was included in this study, participants engaged in significantly more self-reported physical activity at weeks 13 and 24 as compared to baseline. Social cognitions, body composition and strength were also positively impacted suggesting this intervention technique may be feasible for treating obese adolescents.

People with stroke do not achieve adequate levels of physical exercise following discharge from rehabilitation. We developed a group exercise and self-management program (PROPEL), delivered during stroke rehabilitation, to promote uptake of physical activity after discharge. This study aimed to establish the feasibility of a larger study to evaluate the effect of this program on participation in self-directed physical activity. Participants with subacute stroke were recruited at discharge from one of three rehabilitation hospitals; one hospital offered the PROPEL program whereas the other two did not (comparison group; COMP). A high proportion (11/16) of eligible PROPEL program participants consented to the study. Fifteen COMP participants were also recruited. Compliance with wearing an accelerometer for 6 weeks continuously and completing physical activity questionnaires was high (>80%), whereas only 34% of daily heart rate data were available. Individuals who completed the PROPEL program seemed to have higher outcome expectations for exercise, fewer barriers to physical activity, and higher participation in physical activity than COMP participants (Hedge's g ≥ 0.5). The PROPEL program delivered during stroke rehabilitation shows promise for reducing barriers to exercise and increasing participation in physical activity after discharge. This study supports feasibility of a larger randomized trial to evaluate this program. PMID:27313948

Hacker, Eileen Danaher; Peters, Tara; Patel, Pritesh; Rondelli, Damiano

This pilot study tested and refined a free-living physical activity intervention. The investigators evaluated the acceptability and feasibility of the intervention after hematopoietic stem cell transplantation and determined preliminary effects on physical activity, fatigue, muscle strength, functional ability, and quality of life. This pilot study used a 1-group, pretest-posttest design. The free-living physical activity intervention consisted of an education component and 6 weeks of gradually increasing physical activity after discharge from the hospital. The intervention was designed to increase steps by 10% weekly. Subjects were assessed before transplantation and during the seventh week after discharge from the hospital after completing the intervention. Pretest-posttest scores were analyzed with paired t tests. Subject wore the physical activity tracker for an average of 38 of 42 days and met their physical activity goals 57% of the time. Subjects reported significantly less physical fatigue after the free-living physical activity intervention compared with baseline (P = .05). Improvements in quality of life approached significance (P = .06). The findings demonstrate that the free-living physical activity intervention implemented during the very early recovery period after transplantation is feasible and acceptable. The intervention potentially reduces fatigue and improves quality of life. The positive results must be interpreted cautiously given the pilot nature of the study. The evidence supports continued investigation.

There is an association among postural instability, gait dysfunction, and cognitive impairment in subjects with Parkinson's disease (PD). Difficulty in dividing attention, response inhibition, and visuospatial attention deficiencies may contribute to the impairment of motor performance during daily activities. There are strong evidences that physical therapy can prevent physical and cognitive decline in individuals with PD. Recently, the European Physiotherapy Guideline (EPG) was developed based on randomized clinical trials about the effectiveness of the physical therapy to improve the functional deficiencies of individuals with PD. The EPG did not include the use of promising new intervention as virtual reality in PD due the lack of studies about its safety, feasibility and effectiveness. Therefore, this study protocol had as objective to evaluate the feasibility, safety and effectiveness of a physical therapy program-based on the European Physiotherapy Guideline (EPG) compared to Kinect-based training on postural control, gait, cognition, and quality of life (QoL) of Individuals with PD. A single-blind, parallel, randomized, controlled feasibility trial will be conducted with a sample of 32 individuals diagnosed with idiopathic PD. Participants will be allocated into control group (CG) and experimental group (EG). The intervention of the CG will be conventional physical therapy, and the intervention of the EG will be a supervised practice of five Kinect games. Both groups will perform 14 sessions of 1 h each one, twice a week over 7 weeks. Process outcomes will be safety, feasibility, adherence, and acceptability. Safety will be assessed by the proportion of participants who experienced intervention-related adverse events or any serious adverse event during the study period. Feasibility will be assessed through the scores of the games recorded in all training sessions. Adherence will be assessed through the participant's attendance. Acceptability will be the motivation of the participants regarding the interventions. Clinical outcomes will be (1) postural control, (2) cognitive function, (3) balance, (4) gait, and (5) QoL. Individuals will be assessed pre- and post-interventions and after 30 days by a blinded evaluator. This protocol will clarify if an intervention based on Kinect games will be feasible, safe, and acceptable for individuals with PD compared to conventional physical therapy. We will verify whether the proposed interventions can improve clinical outcomes as postural control, gait, cognition, and QoL of individuals with PD. Our hypothesis is that both Kinect games and conventional physical therapy will be feasible, safe, and acceptable for individuals with PD and will promote positive clinical effects. The results of this feasibility study will be used to design a future definitive clinical trial. Unique identification number in WHO Trial Registration: U1111-1171-0371.

use of virtual reality and commercial gaming systems (VR/gaming) at home by older adults is receiving attention as a means of enabling physical activity. to summarise evidence for the effectiveness and feasibility of VR/gaming system utilisation by older adults at home for enabling physical activity to improve impairments, activity limitations or participation. a systematic review searching 12 electronic databases from 1 January 2000-10 July 2012 using key search terms. Two independent reviewers screened yield articles using pre-determined selection criteria, extracted data using customised forms and applied the Cochrane Collaboration Risk of Bias Tool and the Downs and Black Checklist to rate study quality. fourteen studies investigating the effects of VR/gaming system use by healthy older adults and people with neurological conditions on activity limitations, body functions and physical impairments and cognitive and emotional well-being met the selection criteria. Study quality ratings were low and, therefore, evidence was not strong enough to conclude that interventions were effective. Feasibility was inconsistently reported in studies. Where feasibility was discussed, strong retention (≥70%) and adherence (≥64%) was reported. Initial assistance to use the technologies, and the need for monitoring exertion, aggravation of musculoskeletal symptoms and falls risk were reported. existing evidence to support the feasibility and effectiveness VR/gaming systems use by older adults at home to enable physical activity to address impairments, activity limitations and participation is weak with a high risk of bias. The findings of this review may inform future, more rigorous research.

Since 1960’s, particle colliders have been in the forefront of particle physics, 29 total have been built and operated, 7 are in operation now. At present the near term US, European and international strategies of the particle physics community are centered on full exploitation of the physics potential of the Large Hadron Collider (LHC) through its high-luminosity upgrade (HL-LHC). The future of the world-wide HEP community critically depends on the feasibility of possible post-LHC colliders. The concept of the feasibility is complex and includes at least three factors: feasibility of energy, feasibility of luminosity and feasibility of cost. Here wemore » overview all current options for post-LHC colliders from such perspective (ILC, CLIC, Muon Collider, plasma colliders, CEPC, FCC, HE-LHC) and discuss major challenges and accelerator R&D required to demonstrate feasibility of an energy frontier accelerator facility following the LHC. We conclude by taking a look into ultimate energy reach accelerators based on plasmas and crystals, and discussion on the perspectives for the far future of the accelerator-based particle physics. This paper largely follows previous study [1] and the presenta ion given at the ICHEP’2016 conference in Chicago [2].« less

The first results of an ongoing preliminary-concept and detailed-feasibility study of a zero-gravity earth-orbital cloud physics research facility are reviewed. Current planning and thinking are being shaped by two major conclusions of this study: (1) there is a strong requirement for and it is feasible to achieve important and significant research in a zero-gravity cloud physics facility; and (2) some very important experiments can be accomplished with 'off-the-shelf' type hardware by astronauts who have no cloud-physics background; the most complicated experiments may require sophisticated observation and motion subsystems and the astronaut may need graduate level cloud physics training; there is a large number of experiments whose complexity varies between these two extremes.

The objectives of the study were to describe the feasibility of an intervention in older women based on folk dances of the Colombian Caribbean region, and to analyze the effects of the intervention on physical fitness and health-related quality of life (HRQoL). A pilot study was conducted in a sample of 27 participants, 15 in the intervention group (IG) and 12 in the comparison group (CG). Caribbean Colombian dance rhythms were introduced as an intervention that lasted 12 weeks. Recruitment and retention was not optimal. Treatment fidelity components indicated that intervention was administered as intended. IG participants showed positive and statistically significant changes in some components of physical fitness. No significant changes were observed in HRQoL indicators for either group. In conclusion, the intervention was feasible, but recruitment and retention was challenging. Folk dances of the Colombian Caribbean region provoked significant results in physical fitness but not in HRQoL.

Rural Canadians are at increased risk of metabolic syndrome. Physical inactivity is a primary target for preventing and reversing metabolic syndrome. Adherence to lifestyle interventions may be enhanced using cell phones and self-monitoring technologies. This study investigated the feasibility of a physical activity and self-monitoring intervention targeting high-risk adults in rural Ontario. Rural adults (n = 25, mean = 57.0 ± 8.7 years) with ≥ 2 criteria for metabolic syndrome participated in an 8-week stage-matched physical activity and self-monitoring intervention. Participants monitored blood glucose, blood pressure, weight, and physical activity using self-monitoring devices and Blackberry Smart phones. VO2max, stage of change, waist circumference, weight, blood lipids, and HbA1c were measured at weeks 1, 4, and 8. Adherence to self-monitoring was > 94%. Participants' experiences and perceptions of the technology were positive. Mean stage of change increased 1 stage, physical activity increased 26%, and predicted VO2max increased 17% (P < .05). Significant changes in weight, waist circumference, diastolic blood pressure, LDL cholesterol, and total cholesterol were found. This stage-matched technology intervention for increased physical activity was feasible and effective.

This was a mixed-methods case study of one-to-one yoga for people with TBI included three people. We completed assessments before and after the 8-week yoga intervention and included measures of balance, balance confidence, pain, range of motion, strength and mobility. Qualitative interviews were included at the post-assessment. We include a percent change calculation and salient quotes that represent the perceived impact of the yoga intervention. All participants completed the yoga intervention and all demonstrated improvements in physical outcome measures. For the group, balance increased by 36%, balance confidence by 39%, lower extremity strength by 100% and endurance by 105%. Qualitative data support the use of yoga to improve multiple aspects of physical functioning, one participant stated: "I mean it's rocked my world. It's changed my life. I mean all the different aspects. I mean physically, emotionally, mentally, it's given me you know my life back…". Yoga, delivered in a one-to-one setting, appears to be feasible and beneficial to people with chronic TBI. Chronic traumatic brain injury (TBI) leads to many aspects of physical functioning impairment. Yoga delivered in a one-to-one setting may be feasible and beneficial for people with chronic TBI.

Background To be an older woman, live alone, have chronic pain, and be dependent on support are all factors that may have an impact on daily life. One way to promote ability in everyday activities in people with pain-related conditions is to use individualized, integrated behavioral medicine in physical therapy interventions. How this kind of intervention works for older women living alone at home, with chronic pain, and dependent on formal care to manage their everyday lives has not been studied. The aim was to explore the feasibility of a study and to evaluate an individually tailored integrated behavioral medicine in physical therapy intervention for the target group of women. Materials and methods The study was a 12-week randomized trial with two-group design. Primary effect outcomes were pain-related disability and morale. Secondary effect outcomes focused on pain-related beliefs, self-efficacy for exercise, concerns of falling, physical activity, and physical performance. Results In total, 23 women agreed to participate in the study and 16 women completed the intervention. The results showed that the behavioral medicine in physical therapy intervention was feasible. No effects were seen on the primary effect outcomes. The experimental intervention seemed to improve the level of physical activity and self-efficacy for exercise. Some of the participants in both groups perceived that they could manage their everyday life in a better way after participation in the study. Conclusion Results from this study are encouraging, but the study procedure and interventions have to be refined and tested in a larger feasibility study to be able to evaluate the effects of these kinds of interventions on pain-related disability, pain-related beliefs, self-efficacy in everyday activities, and morale in the target group. Further research is also needed to refine and evaluate effects from individualized reminder routines, support to collect self-report data, safety procedures for balance training, and training of personnel to enhance self-efficacy.

To select relevant and feasible instruments for the revision of the Dutch clinical practice guideline for physical therapy in patients with stroke. In this implementation study a comprehensive proposal for ICF categories and matching instruments was developed, based on reliability and validity. Relevant instruments were then selected in a consensus round by 11 knowledge brokers who were responsible for the implementation of the selected instruments. The feasibility of the selected instruments was tested by 36 physical therapists at different work settings within stroke services. Finally, instruments that were deemed relevant and feasible were included in the revised guideline. A total of 28 instruments were recommended for inclusion in the revised guideline. Nineteen instruments were retained from the previous guideline. Ten new instruments were tested in clinical practice, seven of which were found feasible. Two more instruments were added after critical appraisal of the set of the measurement instruments. The revised guideline contains 28 relevant and feasible instrument selected and tested in clinical practice by physical therapists. Further education and implementation is needed to integrate instruments in clinical practice. Further research is proposed for developing and implementing a core set of measurement instruments to be used at fixed time points to establish data registries that allow for continuous improvement of rehabilitation for stroke patients. Implications for Rehabilitation The revised Dutch Stroke Physical Therapy Guideline recommends a total of 28 instruments, that are relevant and feasible for clinical practice of physical therapist in the different settings of stroke rehabilitation. The selection of instrument in daily practice should be part of the clinical reasoning process of PTs and be tailored to individual patients' needs and the degree of priority of the affected ICF category. Suggested education strategies for further integration of instruments in of the daily practice of PTs in Stroke Rehabilitation are: 'Training on the job' and 'peer assessment in clinical situations'.

There are challenges for researchers and clinicians to select the most appropriate physical activity tool, and a balance between precision and feasibility is needed. Currently it is unclear which physical activity tool should be used to assess physical activity in Bronchiectasis. The aim of this research is to compare assessment methods (pedometer and IPAQ) to our criterion method (ActiGraph) for the measurement of physical activity dimensions in Bronchiectasis (BE), and to assess their feasibility and acceptability. Patients in this analysis were enrolled in a cross-sectional study. The ActiGraph and pedometer were worn for seven consecutive days and the IPAQ was completed for the same period. Statistical analyses were performed using SPSS 20 (IBM). Descriptive statistics were used; the percentage agreement between ActiGraph and the other measures were calculated using limits of agreement. Feedback about the feasibility of the activity monitors and the IPAQ was obtained. There were 55 (22 male) data sets available. For step count there was no significant difference between the ActiGraph and Pedometer, however, total physical activity time (mins) as recorded by the ActiGraph was significantly higher than the pedometer (mean ± SD, 232 (75) vs. 63 (32)). Levels of agreement between the two devices was very good for step count (97% agreement); and variation in the levels of agreement were within accepted limits of ±2 standard deviations from the mean value. IPAQ reported more bouted- moderate - vigorous physical activity (MVPA) [mean, SD; 167(170) vs 6(9) mins/day], and significantly less sedentary time than ActiGraph [mean, SD; 362(115) vs 634(76) vmins/day]. There were low levels of agreement between the two tools (57% sedentary behaviour; 0% MVPA 10+ ), with IPAQ under-reporting sedentary behaviour and over-reporting MVPA 10+ compared to ActiGraph. The monitors were found to be feasible and acceptable by participants and researchers; while the IPAQ was accepta ble to use, most patients required assistance to complete it. Accurate measurement of physical activity is feasible in BE and will be valuable for future trials of therapeutic interventions. ActiGraph or pedometer could be used to measure simple daily step counts, but ActiGraph was superior as it measured intensity of physical activity and was a more precise measure of time spent walking. The IPAQ does not appear to represent an accurate measure of physical activity in this population. Clinical Trials Registration Number NCT01569009 : Physical Activity in Bronchiectasis.

Background Pharmacotherapies for smoking cessation have not been adequately tested in pregnancy and women are reluctant to use them. Behavioural support alone has a modest effect on cessation rates; therefore, more effective interventions are needed. Even moderate intensity physical activity (e.g. brisk walk) reduces urges to smoke and there is some evidence it increases cessation rates in non-pregnant smokers. Two pilot studies assessed i) the feasibility of recruiting pregnant women to a trial of physical activity for smoking cessation, ii) adherence to physical activity and iii) womens' perceptions of the intervention. Methods Pregnant smokers volunteered for an intervention combining smoking cessation support, physical activity counselling and supervised exercise (e.g. treadmill walking). The first study provided six weekly treatment sessions. The second study provided 15 sessions over eight weeks. Physical activity levels and continuous smoking abstinence (verified by expired carbon monoxide) were monitored up to eight months gestation. Results Overall, 11.6% (32/277) of women recorded as smokers at their first antenatal booking visit were recruited. At eight months gestation 25% (8/32) of the women achieved continuous smoking abstinence. Abstinent women attended at least 85% of treatment sessions and 75% (6/8) achieved the target level of 110 minutes/week of physical activity at end-of-treatment. Increased physical activity was maintained at eight months gestation only in the second study. Women reported that the intervention helped weight management, reduced cigarette cravings and increased confidence for quitting. Conclusion It is feasible to recruit pregnant smokers to a trial of physical activity for smoking cessation and this is likely to be popular. A large randomised controlled trial is needed to examine the efficacy of this intervention. PMID:18811929

Abstract Background. Self-management and self-efficacy for physical activity is not routinely considered in neurologic rehabilitation. Objective. This study assessed feasibility and outcomes of a 14-week physical activity self-management and coaching intervention compared with social contact in Huntington disease (HD) to inform the design of a future full-scale trial. Design. Assessor blind, multisite, randomized pilot feasibility trial. Setting. Participants were recruited and assessed at baseline, 16 weeks following randomization, and then again at 26 weeks in HD specialist clinics with intervention delivery by trained coaches in the participants’ homes. Patients and Intervention. People with HD were allocated to the ENGAGE-HD physical activity coaching intervention or a social interaction intervention. Measurements. Eligibility, recruitment, retention, and intervention participation were determined at 16 weeks. Other outcomes of interest included measures of mobility, self-efficacy, physical activity, and disease-specific measures of motor and cognition. Fidelity and costs for both the physical activity and social comparator interventions were established. Results. Forty percent (n = 46) of eligible patients were enrolled; 22 were randomized to the physical intervention and 24 to social intervention. Retention rates in the physical intervention and social intervention were 77% and 92%, respectively. Minimum participation criteria were achieved by 82% of participants in the physical intervention and 100% in the social intervention. There was no indication of between-group treatment effects on function; however, increases in self-efficacy for exercise and self-reported levels of physical activity in the physical intervention lend support to our predefined intervention logic model. Limitations. The use of self-report measures may have introduced bias. Conclusions. An HD physical activity self-management and coaching intervention is feasible and worthy of further investigation.

The transition from adolescence to adulthood is a 'high-risk' period for weight gain in the general population. There is speculation that this may also be a risk period for adults with intellectual disabilities; however, there has been no research which has monitored change in health indicators. Since adults with intellectual disabilities have higher rates of obesity and engage in more sedentary behaviour and less physical activity than the general population, there is a need to understand more about the lifestyle behaviours of this population during the transition to adulthood. This protocol paper will provide details of the moving on and feeling good feasibility study, designed for young people with intellectual disabilities. A multi-point recruitment strategy will be used to recruit 30 participants with a mild-moderate level of intellectual disability. The aim of the feasibility study is to examine the feasibility of recruitment, participant retention and the measurement of relevant health behaviour outcomes. The study will assess the feasibility of monitoring weight, diet and physical activity levels in adolescents over a 12-month transitional period from school to adult life. This mixed method study will provide insight into the lives of young people with intellectual disabilities and will examine the use of Walker et al.'s social-ecological approach to promote self-determination specific to lifestyle behaviours, during this transition period. Baseline data will be collected during the final year of school, with follow-up data collection at 6 and 12 months. Anthropometric (weight, height, waist and hip circumference), objective physical activity measures (7-day accelerometer wear) and dietary and choice measures will be collected at each time point to assess the feasibility of measuring diet patterns, food frequency, physical activity and BMI. Furthermore, ten participants will be selected for short semi-structured scoping interviews at baseline and 12-month follow-up, to gain information on psychological, social and environmental factors which might affect behaviour change. The outcomes from the feasibility study will aid the development and piloting of a sufficiently powered randomised controlled trial. This would allow us to evaluate the effectiveness and sustainability of a lifestyle behaviour intervention, over a 5-year transition period.

Background Cancer survivors are at increased risk for second malignancies, cardiovascular disease, diabetes, and functional decline. Evidence suggests that a healthful diet and physical activity may reduce the risk of chronic disease and improve health in this population. Methods We conducted a feasibility study to evaluate a vegetable gardening intervention that paired 12 adult and child cancer survivors with Master Gardeners to explore effects on fruit and vegetable intake, physical activity, quality-of-life, and physical function. Throughout the year-long study period, the survivor-Master Gardener dyads worked together to plan/plant 3 gardens, harvest/rotate plantings, and troubleshoot/correct problems. Data on diet, physical activity, and quality-of-life were collected via surveys; anthropometrics and physical function were objectively measured. Acceptability of the intervention was assessed with a structured debriefing survey. Results The gardening intervention was feasible (robust enrollment; minimal attrition) and well-received by cancer survivors and Master Gardeners. Improvement in 3 of 4 objective measures of strength, agility, and endurance was observed in 90% of survivors, with the following change scores (median [interquartile range]) noted between baseline and 1-year follow-up: hand grip test (+4.8 [3.0, 6.7] kg), 8 foot Get-Up-and-Go (−1.0 [−1.8, −0.2] seconds), 30-second chair stand (+3.0 [−1.0, 5.0] stands), and 6-minute walk (+38 [20, 160] feet). Increases of ≥1 fruit and vegetable serving/ day and ≥30 minutes/week of physical activity were observed in 40% and 60%, respectively. Conclusion These preliminary results support the feasibility and acceptability of a mentored gardening intervention and suggest that it may offer a novel and promising strategy to improve fruit and vegetable consumption, physical activity, and physical function in cancer survivors. A larger randomized controlled trial is needed to confirm our results. PMID:23438359

The objectives of this study were to develop a scale for measuring the highest level of mobility in adult ICU patients and to assess its feasibility and inter-rater reliability. Growing evidence supports the feasibility, safety and efficacy of early mobilization in the intensive care unit (ICU). However, there are no adequately validated tools to quickly, easily, and reliably describe the mobility milestones of adult patients in ICU. Identifying or developing such a tool is a priority for evaluating mobility and rehabilitation activities for research and clinical care purposes. This study was performed at two ICUs in Australia. Thirty ICU nursing, and physiotherapy staff assessed the feasibility of the 'ICU Mobility Scale' (IMS) using a 10-item questionnaire. The inter-rater reliability of the IMS was assessed by 2 junior physical therapists, 2 senior physical therapists, and 16 nursing staff in 100 consecutive medical, surgical or trauma ICU patients. An 11 point IMS scale was developed based on multidisciplinary input. Participating clinicians reported that the scale was clear, with 95% of respondents reporting that it took <1 min to complete. The junior and senior physical therapists showed the highest inter-rater reliability with a weighted Kappa (95% confidence interval) of 0.83 (0.76-0.90), while the senior physical therapists and nurses and the junior physical therapists and nurses had a weighted Kappa of 0.72 (0.61-0.83) and 0.69 (0.56-0.81) respectively. The IMS is a feasible tool with strong inter-rater reliability for measuring the maximum level of mobility of adult patients in the ICU. Copyright © 2014 Elsevier Inc. All rights reserved.

A 12-week interdisciplinary rehabilitation trial in patients with gliomas - a feasibility study.

Hansen, Anders; Søgaard, Karen; Minet, Lisbeth Rosenbek; Jarden, Jens Ole

2018-06-01

This report aims to assess the safety and feasibility of using an interdisciplinary rehabilitation intervention for a future randomized controlled trial in patients with gliomas in the initial treatment phase. We conducted an outpatient two-part rehabilitation intervention that involved six weeks of therapeutic supervised training (part one) and six weeks of unsupervised training in a local gym following a training protocol (part two). Predefined feasibility objectives of safety (100%), consent rate (>80%), drop-out (<20%), adherence (>80%) and patient satisfaction (>80%) was achieved at part one. However, the failure to meet predefined feasibility objectives of drop-out, adherence and patient satisfaction of the unsupervised intervention at part two have led to a protocol revision for a future randomized controlled trial. This study demonstrates that an intensive rehabilitation intervention of physical therapy and occupational therapy in the initial treatment phase of patients with gliomas whose Karnofsky performance status is ≥70 is safe and feasible, if relevant inclusion criteria and precautionary screening are made. With the revised protocol, we are confident that the foundation for conducting a successful randomized controlled trial among these vulnerable patients has been established. Implications for rehabilitation Brain tumors constitute some of the most challenging cancer diagnoses presenting for rehabilitation intervention. Patients with gliomas experiences limitations in physical functioning, cognition, and emotional wellbeing. In a relatively small sample this study shows that supervised physical- and occupational therapy in patients with gliomas is safe and feasible in the initial treatment phase. Patients with gliomas can potentially improve functioning through interdisciplinary rehabilitation.

To feasibility test a 12-week church-based physical activity intervention that was culturally sensitive, age- and gender specific directed at changing attitudes of Black adolescent girls' to be more physically active. A one-group pre- and posttest design was used. A convenience sample of Black adolescent girls between the age of 12-18 (n = 41). A 60-min 12-week church-based program that included interactive educational sessions followed by a high energy dance aerobics class was used. Data were collected on biophysical measures. Surveys were used to assess the following variables: attitudes, enjoyment, self-efficacy, intention, social and family support, and PA levels. Paired t-tests and repeated measures ANOVA revealed no significant changes in key variables. Positive changes were noted in the odds ratios for attitudes, self-efficacy, and intention. Body mass index, metabolic equivalent tasks, and fitness showed positive trends from pre to post intervention. Family support was significantly correlated with physical activity level (p < .01). The study showed that physical activity programs in Black churches aimed at Black adolescent girls are feasible. Participants evaluated the intervention very favorably. Family support may be a key factor in increasing physical activity levels in Black adolescent girls. © 2012 Wiley Periodicals, Inc.

The popularity of active video games (AVGs) has skyrocketed over the last decade. However, research suggests that the most popular AVGs, which rely on synchronous integration between players' activity and game features, fail to promote physical activity outside of the game or for extended periods of engagement. This limitation has led researchers to consider AVGs that involve asynchronous integration of players' ongoing physical activity with game features. Rather than build an AVG de novo, we selected an established sedentary video game uniquely well suited for the incorporation of asynchronous activity: online fantasy sports. The primary aim of this study was to explore the feasibility of a new asynchronous AVG-active fantasy sports-designed to promote physical activity. We conducted two pilot studies of an active fantasy sports game designed to promote physical activity. Participants wore a low cost triaxial accelerometer and participated in an online fantasy baseball (Study 1, n=9, 13-weeks) or fantasy basketball (Study 2, n=10, 17-weeks) league. Privileges within the game were made contingent on meeting weekly physical activity goals (eg, averaging 10,000 steps/day). Across the two studies, the feasibility of integrating physical activity contingent features and privileges into online fantasy sports games was supported. Participants found the active fantasy sports game enjoyable, as or more enjoyable than traditional (sedentary) online fantasy sports (Study 1: t8=4.43, P<.01; Study 2: t9=2.09, P=.07). Participants in Study 1 increased their average steps/day, t8=2.63, P<.05, while participants in Study 2 maintained (ie, did not change) their activity, t9=1.57, P=.15). In postassessment interviews, social support within the game was cited as a key motivating factor for increasing physical activity. Preliminary evidence supports potential for the active fantasy sports system as a sustainable and scalable intervention for promoting adult physical activity.

Cognitive impairment after critical illness is common and debilitating. We developed a cognitive therapy program for critically ill patients and assessed the feasibility and safety of administering combined cognitive and physical therapy early during a critical illness. We randomized 87 medical and surgical ICU patients with respiratory failure and/or shock in a 1:1:2 manner to three groups: usual care, early once-daily physical therapy, or early once-daily physical therapy plus a novel, progressive, twice-daily cognitive therapy protocol. Cognitive therapy included orientation, memory, attention, and problem-solving exercises, and other activities. We assessed feasibility outcomes of the early cognitive plus physical therapy intervention. At 3 months, we also assessed cognitive, functional, and health-related quality of life outcomes. Data are presented as median (interquartile range) or frequency (%). Early cognitive therapy was a delivered to 41/43 (95%) of cognitive plus physical therapy patients on 100% (92-100%) of study days beginning 1.0 (1.0-1.0) day following enrollment. Physical therapy was received by 17/22 (77%) of usual care patients, by 21/22 (95%) of physical therapy only patients, and 42/43 (98%) of cognitive plus physical therapy patients on 17% (10-26%), 67% (46-87%), and 75% (59-88%) of study days, respectively. Cognitive, functional, and health-related quality of life outcomes did not differ between groups at 3-month follow-up. This pilot study demonstrates that early rehabilitation can be extended beyond physical therapy to include cognitive therapy. Future work to determine optimal patient selection, intensity of treatment, and benefits of cognitive therapy in the critically ill is needed.

Pacing, Conventional Physical Activity and Active Video Games to Increase Physical Activity for Adults with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Protocol for a Pilot Randomized Controlled Trial

PubMed Central

Smith, Ashleigh E; Davison, Kade

2017-01-01

Background Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a serious illness of biological origin characterized by profound physical and cognitive exhaustion and postexertion malaise. Pacing is a common strategy used to manage available energy and complete activities of daily living; yet little research has investigated this as a strategy to increase physical activity levels. Typically, people living with ME/CFS are faced by unique barriers to physical activity participation and are less physically active than healthy peers. As such they are at increased risk of physical inactivity–related health consequences. Active video games may be a feasible and acceptable avenue to deliver physical activity intervention by overcoming many of the reported barriers to participation. Objective The primary objective of this pilot study is to determine the feasibility and acceptability of active video games to increase physical activity levels of people with ME/CFS. The secondary aims are to explore the preliminary effectiveness of pacing and active video gaming to pacing alone and pacing plus conventional physical activity to increase the physical activity levels of adults with ME/CFS and explore the relationship between physical activity and cumulative inflammatory load (allostatic load). Methods This study will use a mixed method design, with a 3-arm pilot randomized controlled trial, exit interviews, and collection of feasibility and process data. A total of 30 adults with ME/CFS will be randomized to receive either (1) pacing, (2) pacing and conventional physical activity, or (3) pacing and active video gaming. The intervention duration will be 6 months, and participants will be followed up for 6 months postintervention completion. The intervention will be conducted in the participant’s home, and activity intensity will be determined by continuously monitored heart rate and ratings of perceived exertion. Feasibility and acceptability and process data will be collected during and at the end of the intervention. Health-related outcomes (eg, physical activity, blood samples, quality of life, and functioning) will be collected at baseline, end of intervention, and 6 months after intervention completion. Results This protocol was developed after 6 months of extensive stakeholder and community consultation. Enrollment began in January 2017; as of publication, 12 participants were enrolled. Baseline testing is scheduled to commence in mid-2017. Conclusions This pilot study will provide essential feasibility and acceptability data which will guide the use of active video games for people with ME/CFS to increase their physical activity levels. Physical activity promotion in this clinical population has been poorly and under-researched, and any exploration of alternative physical activity options for this population is much needed.

A general presumption is that any advice from physicians would likely be taken seriously by patients, and patients are more likely to see their doctors in the event of any health complaints than any other health professionals. The perceptions and practice of Nigerian physicians on their role in physical activity promotion are not well known. This study aimed to determine the knowledge of physical activity message, confidence, role perceptions, barriers and feasibility of physical activity promotion among physicians in two tertiary health institutions in North-Eastern Nigeria. A total of 153 (84.5% response) physicians at the University of Maiduguri Teaching Hospital and Federal Medical Center Yola completed a previously developed questionnaire that elicited information on their knowledge, barrier, feasibility, role and confidence in physical activity promotion. Physicians in this study reported fairly good knowledge (mean score=14.7±2.2/20), minimal or little barrier to physical activity promotion (mean score=24.4±3.5/30), perceived physical activity promotion as their role (mean score=12.9±1.6/15), were confident in their ability to discuss and recommend exercises for physical activity promotion (mean score=7.9±1.3/ 10) and believed promoting physical activity was feasible for them (mean score=15.0±2.5/20). The physicians had good disposition to physical activity promotion (Mean score=78.5±6.7/100), but male physicians showed better disposition than their female counterparts. Overall these cohorts of physicians are somewhat knowledgeable on physical activity promotion and are positively disposed to promoting physical activity among their patients. These findings can be leveraged upon to optimize outcome of campaigns or interventions to change physical activity behaviour in Nigerian populace.

Miller, Clint T; Teychenne, Megan; Maple, Jaimie-Lee

Exercise training is an essential component of falls prevention strategies, but they do not fully address components of physical function that leads to falls. The training approaches to achieve this may not be perceived as appropriate or even feasible in older adults. This study aims to assess the perceived feasibility and acceptability of novel exercise training approaches not usually prescribed to older adults. Fourteen adults were exposed to conceptually and physically demanding exercises. Interviews were then conducted to determine perceptions and acceptability of individual exercise tasks. Qualitative thematic analysis was used to identify themes. Safety and confidence, acceptability, and population participation were the key themes identified. Staff knowledge, presence, program design, and overt safety equipment were important for alleviating initial apprehension. Although physically demanding, participants expressed satisfaction when challenged. Prior disposition, understanding the value, and the appeal of novel exercises were perceived to influence program engagement. Given the evidence for acceptability, this type of training is feasible and may be appropriate as part of an exercise training program for older adults. Further research should be conducted to confirm that the physical adaptations to exercise training approaches as presented in this study occur in a similar manner to that observed in younger adults, and to also determine whether these adaptations lead to prolonged independence and reduced falls in older adults compared to usual care.

2017-09-27

Despite its well-established benefits, physical activity (PA) engagement is low in the adult population; evidence suggests that this is especially a concern for women > 60 years. The purpose of this mixed methods study was to explore the feasibility of a six-week randomized control trial of Self-Determination Theory-based dance and walking programs for older women. Primary outcomes were feasibility measures: recruitment, retention, and satisfaction. Secondary outcomes included self-reported PA, behavioural regulations, and psychological needs. Thirty-five women completed the study (M = 62.8 ± 4.8 years), representing 39% recruitment and 95% retention rate. Both programs were highly attended. Exploratory effect sizes for secondary measures were promising. Emergent themes highlighted the importance of servant leadership concepts in the group setting for motivating PA. Our findings provide support for expanding this trial to a full-scale study.

Wireless and mobile phone technology as a method of data collection will increase alongside conventional methods. The aim of the present study was to evaluate the use of a mobile phone application for recording symptoms and physical activity exertion during an experimental physical exercise study. An experimental study on the effects of physical exercise on the well-being of menopausal women included 158 subjects between 44 and 63 years of age. The women were randomized into intervention and control groups. All participants in both groups reported daily symptoms by responding to morning and evening questionnaires via mobile phones. The usability of the mobile phone as a data collector tool was evaluated with the System Usability Scale (SUS) questionnaire 2 months after the intervention. The feasibility evaluation was based on the frequency of responses and open questions. The response rates were about 70% to both morning and evening questionnaires. The average frequency of responses (n =158) to morning questionnaires was 125 (±40)/170 (±14) and to evening questionnaires was 118 (±40)/171 (±14). The response rate did not differ between the intervention and the control groups. The SUS score was on average 75.4 (range, 0-100; n =107). A mobile phone diary is a feasible and usable tool for data collection in clinical trials.

Will there be energy frontier colliders after LHC?

DOE Office of Scientific and Technical Information (OSTI.GOV)

Shiltsev, Vladimir

2016-09-15

High energy particle colliders have been in the forefront of particle physics for more than three decades. At present the near term US, European and international strategies of the particle physics community are centered on full exploitation of the physics potential of the Large Hadron Collider (LHC) through its high-luminosity upgrade (HL-LHC). The future of the world-wide HEP community critically depends on the feasibility of possible post-LHC colliders. The concept of the feasibility is complex and includes at least three factors: feasibility of energy, feasibility of luminosity and feasibility of cost. Here we overview all current options for post-LHC collidersmore » from such perspective (ILC, CLIC, Muon Collider, plasma colliders, CEPC, FCC, HE-LHC) and discuss major challenges and accelerator R&D required to demonstrate feasibility of an energy frontier accelerator facility following the LHC.

Significant benefits accrue from increasing physical activity levels in people with a history of cancer. Physical activity levels can be increased using behavioral change interventions in this population. Access to Web portals and provision of activity monitors to provide feedback may support behavior change by encouraging patient engagement in physical therapy. The Web portal evaluated in this study will provide a system to monitor physical activity and sleep, for use by both clinician and patient, along with symptom and health-related quality of life tracking capabilities. The aim of this study was to outline a protocol for a feasibility study focused on a Web-based portal that provides activity monitoring and personalized messaging to increase physical activity in people with cancer. Using a longitudinal cohort design, people with cancer will be serially allocated to 3 intervention cohorts of 20 participants each and followed for 10 weeks. Cohort 1 will be provided a wearable activity monitor and access to a Web-based portal. Cohort 2 will receive the same content as Cohort 1 and in addition will receive a weekly activity summary message. Cohort 3 will receive the same content as Cohorts 1 and 2 and in addition will receive a personalized weekly coaching message. Feasibility of the use of the portal is the primary outcome. Results are expected in early 2018. Outcome measures will include goal attainment and completion rate. This study will provide information about the feasibility of investigating eHealth initiatives to promote physical activity in people with cancer.

Participation in regular physical activity holds key benefits for cancer survivors, yet few cancer survivors meet physical activity recommendations. This study aimed to develop and pilot test a mHealth app referral service aimed at assisting cancer survivors to increase their physical activity. In particular, the study sought to examine feasibility and acceptability of the service and determine preliminary efficacy for physical activity behaviour change. A systematic search identified potentially appropriate Apple (iOS) and Android mHealth apps. The apps were audited regarding the type of physical activity encouraged, evidence-based behavioural strategies and other characteristics, to help match apps to users' preferences and characteristics. A structured service was devised to deliver the apps and counselling, comprising two face-to-face appointments with a mid-week phone or email check-up. The mHealth app referral service was piloted using a pre-post design among 12 cancer survivors. Participants' feedback regarding the service's feasibility and acceptability was sought via purpose-designed questionnaire, and analysed using inductive thematic analysis and descriptive statistics. Change in physical activity was assessed using a valid and reliable self-report tool and analysed using paired t-tests. In line with recommendations for pilot studies, confidence intervals and effect sizes were reported to aid interpretation of clinical significance, with an alpha of 0.2 used to denote statistical significance. Of 374 mHealth apps identified during the systematic search, 54 progressed to the audit (iOS = 27, Android = 27). The apps consistently scored well for aesthetics, engagement and functionality, and inconsistently for gamification, social and behaviour change features. Ten participants completed the pilot evaluation and provided positive feedback regarding the service's acceptability and feasibility. On average, participants increased their moderate-vigorous physical activity by 236 min per week (d = 0.73; 95% CI = -49 to 522; p = 0.09). This study offered initial evidence that a mHealth app referral service for cancer survivors is feasible and acceptable and may increase physical activity levels. The large increase in physical activity is promising, but should be interpreted with caution given the small sample size and lack of control group. Further research is warranted on a larger scale to investigate generalisability, long-term compliance and application in clinical settings.

To establish the feasibility and acceptability of completing a higher dose of the planned physical activity volume among women with ovarian cancer, including those undergoing active treatment. 
. A pre-/post-test exercise intervention. All participants were asked to complete 225 minutes per week of physical activity for 26 weeks. Multiple supports were provided, including exercise DVDs, self-reported logs, and an objective physical activity tracker (Fitbit®).
. Home-based exercise intervention with in-person training and telephone follow-ups.
. 10 women with ovarian cancer who were treated within Penn Medicine in Philadelphia, Pennsylvania.
. Home-based, in-person exercise counseling was provided by an exercise trainer weekly for the first six weeks and then monthly for a total of 26 weeks. Weekly follow-up telephone calls were used to assess exercise adherence and barriers to completing exercise, review symptom changes, and provide behavioral support. 
. Feasibility and acceptability.
. Eight participants completed the study and achieved at least 80% of the prescribed exercise dose. Five participants were undergoing chemotherapy simultaneously. Participants experienced no adverse events during the 26-week intervention. Compared to baseline, average steps increased by 1,593 per day and moderate-intensity physical activity increased by 15 minutes per day. 
. A 225-minutes-per-week exercise program is feasible and acceptable in a population of patients with ovarian cancer. Participants significantly improved their physical activity during the 26-week intervention.
. The findings suggest that nursing professionals could recommend that women with ovarian cancer exercise 225 minutes per week regardless of cancer and/or treatment trajectory. For those experiencing aches and pains, behavioral supports and suggestions of a lower exercise dose are needed to maintain physical activity.

The aim of this study was to promote physical activity in 6th graders by developing and testing the feasibility of an enhanced Presidential Active Lifestyle Award (PALA) program comprised of a peer leadership component and innovative exercise resource toolkit including DVDs. A racially/ethnically diverse sample of students received the standard PALA program (2 control schools, n = 61) or enhanced PALA+Peers program (2 intervention schools, n = 87) during 2006-2007 academic year. Compared with the control condition, the intervention was successful in increasing moderate physical activity in all students (P = .02) and moderate and hard physical activity among girls (P = .03 and P = .04, respectively). Teachers and students reported a high level of satisfaction and receptivity with the intervention. All teachers thought the DVDs were well-received, and 87% of students reported that they would recommend the enhanced program to peers. Coupling peer leadership and DVDs that promote physical activity may be an effective way to increase youth physical activity.

Children who are ethnic minorities, low income and live in urban neighborhoods are at higher risk for obesity. This study examined the feasibility and efficacy of a primary care-based and community partnered obesity intervention in Chinese American children. An experimental design with a historical comparison group was used to explore the feasibility of an obesity intervention for overweight Chinese American children, ages 7-12. Data were collected on weight, height, blood pressure, waist circumference, physical activity, food intake, knowledge, and self-efficacy about diet and physical activity at baseline, 2 months, and 6 months post-baseline. Significant improvements in BMI, blood pressure, and nutrition knowledge and self-efficacy were found in the intervention group. Intervention group reduced their BMI compared to the comparison group (F = 8.65, p = .004). An obesity intervention in primary care setting is feasible and demonstrates a short-term effect on weight loss in Chinese American children.

Physical activity is of paramount importance to enhance the quality of life of childhood cancer survivors. The objectives of this study were to examine the sustainability, feasibility, and acceptability of an adventure-based training and health education program in changing the exercise behavior and enhancing the physical activity levels, self-efficacy, and quality of life of childhood cancer survivors. A follow-up study (12 and 18 months) of a previous study was conducted. Participants in the experimental group (n = 33) joined a 4-day integrated adventure-based training and health education program. The control group (n = 36) received the standard medical care. Changes in exercise behavior, levels of physical activity, self-efficacy, and quality of life were assessed from the time of recruitment, and at 12 and 18 months after starting the intervention. Process evaluation was conducted to determine whether the program was feasible and acceptable to participants. From baseline to 18 months after the intervention, the experimental group reported statistically significant differences in the stages of change in physical activity and higher levels of physical activity, self-efficacy, and quality of life than did the control group. The results of process evaluation revealed that the program was both feasible and acceptable to participants. The program was found to have substantial effects on enhancing the physical activity levels, self-efficacy, and quality of life of childhood cancer survivors over at least 18 months. Healthcare professionals should consider adopting such programs to promote the regular physical activity among childhood cancer survivors.

Exercise referral schemes are recommended by the National Institute for Clinical Excellence (NICE) for physical activity promotion among inactive patients with health conditions or risk factors. Whilst there is evidence for the initial effectiveness and cost-effectiveness of such schemes for increasing physical activity, evidence of long-term effects is limited. Techniques such as goal setting, self-monitoring and personalised feedback may support motivation for physical activity. Technologies such as activity monitoring devices provide an opportunity to enhance delivery of motivational techniques. This paper describes the PACERS study protocol, which aims to assess the feasibility and acceptability of implementing an activity monitor within the existing Welsh National Exercise Referral Scheme (NERS) and proposed evaluation methodology for a full-scale randomised controlled trial. The PACERS study consists of a pilot randomised controlled trial, process evaluation and exploratory economic analyses. Participants will be recruited from the generic pathway of the Welsh NERS and will be randomly assigned to receive the intervention or usual practice. Usual practice is a 16-week structured exercise programme; the intervention consists of an accelerometry-based activity monitor (MyWellnessKey) and an associated web platform (MyWellnessCloud). The primary outcomes are predefined progression criteria assessing the acceptability and feasibility of the intervention and feasibility of the proposed evaluation methodology. Postal questionnaires will be completed at baseline (time 0: T0), 16 weeks after T0 (T1) and 12 months after T0 (T2). Routinely collected data will also be accessed at the same time points. A sub-sample of intervention participants and exercise referral staff will be interviewed following initiation of intervention delivery and at the end of the study. The PACERS study seeks to assess the feasibility of adding a novel motivational component to an existing effective intervention in order to enhance effects on physical activity and support longer-term maintenance. The study will provide insight into the acceptability of activity-monitoring technologies to an exercise referral population and delivery staff. Data from this study will be used to determine whether and how to proceed to a full-scale trial of effectiveness of the intervention, including any necessary refinements to intervention implementation or the proposed evaluation methodology.

Pacing, Conventional Physical Activity and Active Video Games to Increase Physical Activity for Adults with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome: Protocol for a Pilot Randomized Controlled Trial.

PubMed

Ferrar, Katia Elizabeth; Smith, Ashleigh E; Davison, Kade

2017-08-01

Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a serious illness of biological origin characterized by profound physical and cognitive exhaustion and postexertion malaise. Pacing is a common strategy used to manage available energy and complete activities of daily living; yet little research has investigated this as a strategy to increase physical activity levels. Typically, people living with ME/CFS are faced by unique barriers to physical activity participation and are less physically active than healthy peers. As such they are at increased risk of physical inactivity-related health consequences. Active video games may be a feasible and acceptable avenue to deliver physical activity intervention by overcoming many of the reported barriers to participation. The primary objective of this pilot study is to determine the feasibility and acceptability of active video games to increase physical activity levels of people with ME/CFS. The secondary aims are to explore the preliminary effectiveness of pacing and active video gaming to pacing alone and pacing plus conventional physical activity to increase the physical activity levels of adults with ME/CFS and explore the relationship between physical activity and cumulative inflammatory load (allostatic load). This study will use a mixed method design, with a 3-arm pilot randomized controlled trial, exit interviews, and collection of feasibility and process data. A total of 30 adults with ME/CFS will be randomized to receive either (1) pacing, (2) pacing and conventional physical activity, or (3) pacing and active video gaming. The intervention duration will be 6 months, and participants will be followed up for 6 months postintervention completion. The intervention will be conducted in the participant's home, and activity intensity will be determined by continuously monitored heart rate and ratings of perceived exertion. Feasibility and acceptability and process data will be collected during and at the end of the intervention. Health-related outcomes (eg, physical activity, blood samples, quality of life, and functioning) will be collected at baseline, end of intervention, and 6 months after intervention completion. This protocol was developed after 6 months of extensive stakeholder and community consultation. Enrollment began in January 2017; as of publication, 12 participants were enrolled. Baseline testing is scheduled to commence in mid-2017. This pilot study will provide essential feasibility and acceptability data which will guide the use of active video games for people with ME/CFS to increase their physical activity levels. Physical activity promotion in this clinical population has been poorly and under-researched, and any exploration of alternative physical activity options for this population is much needed.

Stroke results in significant disability, which can be reduced by physical rehabilitation. High levels of repetition and activity are required in rehabilitation, but patients are typically sedentary. Using clinically relevant and fun computer games may be one way to achieve increased activity in rehabilitation. A single-blind randomized controlled trial will be conducted to evaluate the feasibility, efficacy and safety of novel stroke-specific rehabilitation software. This software uses controller-free client interaction and inertial motion sensors. Elements of feasibility include recruitment into the trial, ongoing participation (adherence and dropout), perceived benefit, enjoyment and ease of use of the games. Efficacy will be determined by measuring activity and using upper-limb tasks as well as measures of balance and mobility. The hypothesis that the intervention group will have increased levels of physical activity within rehabilitation and improved physical outcomes compared with the control group will be tested. Results from this study will provide a basis for discussion of feasibility of this interactive video technological solution in an inpatient situation. Differences in activity levels between groups will be the primary measure of efficacy. It will also provide data on measures of upper-limb function, balance and mobility. ACTRN12614000427673 .

People living with acquired brain injury (ABI) are more likely to be physically inactive and highly sedentary and, therefore, to have increased risks of morbidity and mortality. However, many adults with ABI experience barriers to participation in effective physical activity interventions. Remotely delivered self-management programs focused on teaching patients how to improve and maintain their physical activity levels have the potential to improve the overall health of adults with ABI. The study objective was to evaluate the acceptability and feasibility of a remotely delivered self-management program aimed at increasing physical activity among adults who dwell in the community and have ABI. A single-group design involving comparison of baseline measures with those taken immediately after intervention and at a 3-month follow-up was used in this study. The myMoves Program comprises 6 modules delivered over 8 weeks via email. Participants were provided with regular weekly contact with an experienced physical therapist via email and telephone. The primary outcomes were the feasibility (participation, attrition, clinician time, accessibility, and adverse events) and acceptability (satisfaction, worthiness of time, and recommendation) of the myMoves Program. The secondary outcomes were objective physical activity data collected from accelerometers, physical activity self-efficacy, psychological distress, and participation. Twenty-four participants commenced the program (20 with stroke, 4 with traumatic injury), and outcomes were collected for 23 and 22 participants immediately after the program and at a 3-month follow-up, respectively. The program required very little clinician contact time, with an average of 32.8 minutes (SD=22.8) per participant during the 8-week program. Acceptability was very high, with more than 95% of participants being either very satisfied or satisfied with the myMoves Program and stating that it was worth their time. All participants stated that they would recommend the program to others with ABI. The results were obtained from a small sample; hence, the results may not be generalizable to a larger ABI population. A remotely delivered self-management program aimed at increasing physical activity is feasible and acceptable for adults with ABI. Further large-scale efficacy trials are warranted. © 2016 American Physical Therapy Association.

In 2013, the Royal Dutch Society for Physical Therapy launched the program "Quality in Motion." This program aims to collect data from electronic health record systems in a registry that is fed back to physical therapists, facilitating quality improvement. The purpose of this study was to describe the development of an implementation strategy for the program and to evaluate the feasibility of building a registry and implementing patient-reported outcome measures (PROMs) in physical therapist practices. A stepwise approach using mixed methods was established in 3 consecutive pilots with 355 physical therapists from 66 practices. Interim results were evaluated using quantitative data from a self-assessment questionnaire and the registry and qualitative data from 21 semistructured interviews with physical therapists. Descriptive statistics and McNemar's symmetry chi-squared test were used to summarize the feasibility of implementing PROMs. PROMs were selected for the 5 most prevalent musculoskeletal conditions in Dutch physical therapist practices. A core component of the implementation strategy was the introduction of knowledge brokers to support physical therapists in establishing the routine use of PROMs in clinical practice and to assist in executing peer assessment workshops. In February 2013, 30.3% of the physical therapist practices delivered 4.4 completed treatment episodes per physical therapist to the registry; this increased to 92.4% in November 2014, delivering 54.1 completed patient episodes per physical therapist. Pre- and posttreatment PROM use increased from 12.2% to 39.5%. It is unclear if the participating physical therapists reflect a representative sample of Dutch therapists. Building a registry and implementing PROMs in physical therapist practices are feasible. The routine use of PROMs needs to increase to ensure valid feedback of outcomes. Using knowledge brokers is promising for implementing the program via peer assessment workshops. © 2017 American Physical Therapy Association

Feasibility of a Dynamic Web Guidance Approach for Personalized Physical Activity Prescription Based on Daily Information From Wearable Technology

PubMed Central

Coolbaugh, Crystal L; Raymond Jr, Stephen C

2015-01-01

Background Computer tailored, Web-based interventions have emerged as an effective approach to promote physical activity. Existing programs, however, do not adjust activities according to the participant’s compliance or physiologic adaptations, which may increase risk of injury and program attrition in sedentary adults. To address this limitation, objective activity monitor (AM) and heart rate data could be used to guide personalization of physical activity, but improved Web-based frameworks are needed to test such interventions. Objective The objective of this study is to (1) develop a personalized physical activity prescription (PPAP) app that combines dynamic Web-based guidance with multi-sensor AM data to promote physical activity and (2) to assess the feasibility of using this system in the field. Methods The PPAP app was constructed using an open-source software platform and a custom, multi-sensor AM capable of accurately measuring heart rate and physical activity. A novel algorithm was written to use a participant’s compliance and physiologic response to aerobic training (ie, changes in daily resting heart rate) recorded by the AM to create daily, personalized physical activity prescriptions. In addition, the PPAP app was designed to (1) manage the transfer of files from the AM to data processing software and a relational database, (2) provide interactive visualization features such as calendars and training tables to encourage physical activity, and (3) enable remote administrative monitoring of data quality and participant compliance. A 12-week feasibility study was performed to assess the utility and limitations of the PPAP app used by sedentary adults in the field. Changes in physical activity level and resting heart rate were monitored throughout the intervention. Results The PPAP app successfully created daily, personalized physical activity prescriptions and an interactive Web environment to guide and promote physical activity by the participants. The varied compliance of the participants enabled evaluation of administrative features of the app including the generation of automated email reminders, participation surveys, and daily AM file upload logs. Conclusions This study describes the development of the PPAP app, a closed-loop technology framework that enables personalized physical activity prescription and remote monitoring of an individual’s compliance and health response to the intervention. Data obtained during a 12-week feasibility study demonstrated the ability of the PPAP app to use objective AM data to create daily, personalized physical activity guidance, provide interactive feedback to users, and enable remote administrative monitoring of data quality and subject compliance. Using this approach, public health professionals, clinicians, and researchers can adapt the PPAP app to facilitate a range of personalized physical activity interventions to improve health outcomes, assess injury risk, and achieve fitness performance goals in diverse populations.

We evaluated feasibility of physical activity measurement by accelerometry among older Malay adults living in semi-rural areas in Malaysia. Results showed that 95% of 146 participants (aged [SD] 67.6 [6.4] years) were compliant in wearing the accelerometer for at least five days. Fifteen participants were asked for re-wear the accelerometer because they did not have enough valid days during the first assessment. Participants wore the accelerometer an average of 15.3 hr in a 24-hr day, with 6.5 (1.2) valid wear days. No significant difference in valid wear day and time was found between men and women. Participants who are single provide more valid wear days compared with married participants (p < .05), and participants with higher levels of education provide longer periods of accelerometer wearing hours (p < .01). Eighty-seven percent of participants reported 'no issues' with wearing the meter. This study suggests that accelerometry is a feasible method to assess the physical activity level among older Malay adults living in semi-rural areas.

In this study, we proposed an absorbed-dose monitoring technique using prompt gamma rays emitted from the reaction between an antiproton and a boron particle, and demonstrated the greater physical effect of the antiproton boron fusion therapy in comparison with proton beam using Monte Carlo simulation. The physical effect of the treatment, which was 3.5 times greater, was confirmed from the antiproton beam irradiation compared to the proton beam irradiation. Moreover, the prompt gamma ray image is acquired successfully during antiproton irradiation to boron regions. The results show the application feasibility of absorbed dose monitoring technique proposed in our study.

Although physical activity may reduce disease burden, fatigue and disability, and improve quality of life among people with multiple sclerosis (MS), many people with MS are physically inactive and spend significant time in sedentary behaviour. Behaviour change interventions may assist people with MS to increase physical activity and reduce sedentary behaviour. However, few studies have investigated their effectiveness using objective measures of physical activity, particularly in the long term. Further, interventions that have proven effective in the short term may not be feasible in clinical practice because of the large amount of support provided. The iStep-MS trial aims to determine the safety, feasibility and acceptability of a behaviour change intervention to increase physical activity and reduce sedentary behaviour among people with MS. Sixty people with MS will be randomised (1:1 ratio) to receive a 12-week intervention or usual care only. The intervention consists of four physical activity consultations with a physiotherapist supported by a handbook and pedometer. Outcomes assessed at baseline, 12 weeks and 9 months are physical activity (ActiGraph wGT3X-BT accelerometer), sedentary behaviour (activPAL3µ), self-reported activity and sitting time, walking capability, fatigue, self-efficacy, participation, quality of life and health service use. The safety of the intervention will be determined by assessing change in pain and fatigue and the incidence of adverse events during the follow-up period. A parallel process evaluation will assess the feasibility and acceptability of the intervention through assessment of fidelity to the programme and semistructured interviews exploring participants' and therapists' experiences of the intervention. The feasibility of conducting an economic evaluation will be determined by collecting data on quality of life and resource use. Research ethics committee approval has been granted from Brunel University London. Results of the trial will be submitted for publication in journals and distributed to people with MS and physiotherapists. ISRCTN15343862 (doi 10.1186/ISRCTN15343862).

2018-02-01

This study mainly discussed the feasibility of manufacturing lightweight aggregates from water purification sludge in Taiwan. They were analysed for the physical and chemical composition before the sintering test for lightweight aggregates in a laboratory. Then the physical and mechanical properties of the synthesized aggregates were assessed. The result showed that the chemical composition of sludge in the water purification plants was within the appropriate range for manufacturing lightweight aggregate as proposed in the literature. The sintering test demonstrated that the particle density of aggregates from the ten types of water purification sludge were mostly less than 1.8 g/cm3. In addition, the dry unit weight, the organic impurity, the ignition loss, and other characteristics of synthesized aggregates met the requirement of CNS standards, while its water absorption and crushing strength also fulfilled the general commercial specifications. Therefore, reclamation of water purification sludge for production of lightweight aggregate is indeed feasible.

Diverse fractions of patients with locally advanced resectable rectal cancer receive neoadjuvant chemoradiotherapy (NACRT). NACRT is known to decrease physical fitness, an undesirable side effect. This pilot aimed to determine the feasibility and preliminary effectiveness of a supervised outpatient physical exercise training program during NACRT in these patients. We included 13 out of 20 eligible patients (11 males, mean ± SD age: 59.1 ± 19.7 years) with rectal cancer who participated in the exercise training program during NACRT. Feasibility was determined by adherence and number of adverse events. Physical fitness was compared at baseline (B), after five (T1) and ten weeks (T2) of training, and eight weeks postoperatively (T3) using repeated-measures analysis of variance. Nine patients (69.2%) completed the program without adverse events. Four patients dropped out. The program was feasible and safe, with a total attendance rate of 95.7%. Leg muscle strength (mean ± SD: 104.0 ± 32.3 versus 144.8 ± 45.6 kg; P < 0.001) and arm muscle strength (mean ± SD: 48.7 ± 13.8 kg versus 36.1 ± 11.0 kg, P = 0.002) increased significantly between B and T2, respectively. A slight, non-significant, increase in functional exercise capacity was found. This pilot demonstrated that a supervised outpatient physical exercise training program for individual patients with locally advanced resectable rectal cancer during NACRT is feasible for a large part of the patients, safe and seems able to prevent an often seen decline in physical fitness during NACRT. A larger study into the cost-effectiveness of this approach is warranted. Copyright © 2016 Elsevier Ltd. All rights reserved.

2017-04-01

The Health Education for Persons with Multiple Sclerosis (HEMS) program was developed in response to the need for interventions aimed at increasing physical activity for individuals with Multiple Sclerosis (MS). It was developed and evaluated using Drum and colleagues (2009) guidelines for implementing health promotion programs for individuals with disabilities. The purpose of this feasibility study is to describe the development, implementation, and evaluation of the HEMS program. Thirteen individuals with MS completed the 8-week health education program. A mixed method approach for evaluation was implemented (i.e., survey and focus groups). Process and resource feasibility demonstrated that over half of the participants attended at least 80% of the weekly sessions. Focus group data provided valuable feedback for future iterations of the program including critiques on the delivery, content, and group support provided. Outcome evaluation showed increases in self-efficacy (survey), improvements in theoretical constructs (focus groups), and increased physical activity (focus groups). Results show that health promotion programs for persons with MS can improve physical activity and related constructs. Next steps will be to revise, implement, and reevaluate the HEMS program in a larger randomized control trial. Published by Elsevier Ltd.

The aim of the present study was to determine the reliability and feasibility of physical fitness tests in female fibromyalgia patients. 100 female fibromyalgia patients (aged 50.6±8.6 years) performed the following tests twice (7 days interval test-retest): chair sit and reach, back scratch, handgrip strength, arm curl, chair stand, 8 feet up and go, and 6-min walk. Significant differences between test and retest were found in the arm curl (mean difference: 1.25±2.16 repetitions, Cohen d=0.251), chair stand (0.99±1.7 repetitions, Cohen d=0.254) and 8 feet up and go (-0.38±1.09 s, Cohen d=0.111) tests. Intraclass correlation coefficients (ICC) range from 0.92 in the arm curl test to 0.96 in the back scratch test. The feasibility of the tests (patients able to complete the test) ranged from 89% in the arm curl test to 100% in the handgrip strength test. Therefore, the reliability and feasibility of the physical fitness tests examined is acceptable for female fibromyalgia patients. © Georg Thieme Verlag KG Stuttgart · New York.

Frailty can be defined as a medical syndrome with multiple causes and contributors, characterized by diminished strength and endurance and reduced physiological function that increases the vulnerability to develop functional dependency and/or death. Studies have shown that the most commonly studied exercise protocol for frail older adults is the multimodal training. Interactive video games (IVGs) involve tasks in virtual environments that combine physical and cognitive demands in an attractive and challenging way. The aim of this study will be to evaluate the feasibility, safety, acceptability, and functional outcomes of playing Nintendo Wii Fit Plus TM (NWFP) for frail older adults. The study is a randomized controlled, parallel group, feasibility trial. Participants will be randomly assigned to the experimental group (EG) and control group (CG). The EG will participate in 14 training sessions, each lasting 50 min, twice a week. In each training session, the participants will play five games, with three attempts at each game. The first attempt will be performed with the assistance of a physical therapist to correct the movements and posture of the patients and subsequent attempts will be performed independently. Scores achieved in the games will be recorded. The participants will be evaluated by a blinded physical therapist at three moments: before and after intervention and 30 days after the end of the intervention (follow-up). We will assess the feasibility, acceptability, safety, and clinical outcomes (postural control, gait, cognition, quality of life, mood, and fear of falling). Due to the deficiencies in multiple systems, studies have shown that multimodal interventions including motor-cognitive stimulation can improve the mobility of frail elderly adults. IVGs, among them the NWFP, are considered as a multimodal motor-cognitive intervention that can potentially improve motor and cognitive functions in the frail elderly. However, there is still no evidence in the literature that proves the feasibility, safety, acceptability, and functional outcomes of this intervention in frail elderly individuals.

Worksites offer a unique opportunity to increase physical activity in persons with both active and sedentary lifestyles. The objective of this study was to examine employee and supervisor perspectives on feasibility and acceptability of 10-minute Instant Recess ® physical activity videos in the worksite. Convenience sample of public and private worksites in Minneapolis/St. Paul, MN. Employees (n = 187) at 13 worksites were recruited by a one-time email invitation to participate in a group Instant Recess break and complete a 15-question survey. One supervisor per site participated in a one-on-one interview to assess suggestions for feasibility of implementation. Likert-type survey responses were averaged per worksite and overall. Interview results were recorded, transcribed, and coded by two authors. Employees were extremely positive about enjoyment, increased productivity, comfort, and feasibility of doing Instant Recess at the same time and place every day (score = 4.29, 4.17, 4.25, and 4.37 out of 5, respectively). However, they did not feel comfortable leading an Instant Recess break (score = 2.68 out of 5). Supervisors voiced during the one-on-one interviews that they enjoyed Instant Recess (13 out of 13 supervisors), were enthusiastic about Instant Recess as a simple and cost-effective entry into worksite wellness (11 out of 13 supervisors), and felt that Instant Recess could be institutionalized by offering it daily at a set time and place (13 out of 13 supervisors). Employees and supervisors at various worksites believed that it is feasible and desirable to offer 10-minute physical activity breaks using videos during the workday.

Physical activity plays an important role in colorectal cancer and accelerometry is more frequently used to measure physical activity. The aim of this study was to evaluate feasibility of physical activity measurement by accelerometry in colorectal cancer patients under free-living conditions at 6, 12 and 24 months after surgery, to evaluate the appropriate wear time and to compare results to pedometry. Colorectal cancer patients (stage 0/I-IV) from the ColoCare study were asked to optionally wear an accelerometer and a pedometer for ten consecutive days 6, 12 and 24 months post-surgery. Participants completed a feedback questionnaire about the accelerometer measurement. The course of moderate-to-vigorous physical activity over the 10 days was investigated. Additionally, daily step counts from accelerometers and pedometers were compared. In total, there were 317 individual time points, at which 198 participants were asked to wear an accelerometer. Fifty-nine% initially agreed to participate and of these, 83% (n = 156) completed the assessment with at least 4 days of data. Twenty-one% more consents were obtained when participants were asked on a face-to-face basis compared to recruitment by telephone (P = 0.0002). There were no significant differences in time spent in moderate-to-vigorous physical activity between different wear-time lengths of accelerometry. Both Spearman and intraclass correlation coefficients showed strong correlations (0.92-0.99 and 0.84-0.99, respectively) of moderate-to-vigorous physical activity across 3, 4, 7 and 10 days measurement. Step counts measured by accelerometry and pedometry were strongly correlated (ρ = 0.91, P < 0.0001). This study suggest that accelerometry is a feasible method to assess physical activity in free-living colorectal cancer patients and that three valid days of physical activity measurement are sufficient for an accurate assessment.

Despite ample evidence demonstrating the protective effect of physical activity, the uptake of regular physical activity among South Asian (SA) women remains relatively low. The purpose of this study was to explore the feasibility and health impacts of implementing a culture- and gender-specific physical activity among SA immigrant women residing in Greater Toronto Area (GTA) in Ontario, Canada. A community-based mixed methods approach combining cohort pretest and posttest design and qualitative methods employing in depth interviews was used. Twenty-seven SA women from the GTA participated in a 6-week, 2 days per week, Bollywood Dance exercise program led by a female SA instructor. The participation rate was considerably high (85%) and approximately 82% of the participants attended 10 or more of the classes offered. The participants' physical measurements (weight, waist and hip, and body mass index) decreased, although not significantly, over the 6-week period and there was an improvement in their physical, mental, and social health. During the face-to-face interviews, participants reported feeling less stressed and tired, being more mentally and physically robust, and having a sense of fulfillment and self-satisfaction. The only common criticism expressed was that the 6-week duration of the intervention was too short. The results showed that the Bollywood Dance was a feasible strategy in engaging SA immigrant women in physical activity. The key aspects when designing culture- and gender-specific dance interventions include community participation and active engagement in planning and implementation of the program, a supportive environment, same gender and culturally attuned dance instructor, easy access, and minimal to no cost.

Objectives To determine the feasibility of conducting a randomized clinical trial designed to compare two methods of manual therapy (myofascial physical therapy (MPT) and global therapeutic massage (GTM)) among patients with urologic chronic pelvic pain syndromes. Materials and Methods Our goal was to recruit 48 subjects with chronic prostatitis/chronic pelvic pain syndrome or interstitial cystitis/painful bladder syndrome at six clinical centers. Eligible patients were randomized to either MPT or GTM and were scheduled to receive up to 10 weekly treatments, each 1 hour in duration. Criteria to assess feasibility included adherence of therapists to prescribed therapeutic protocol as determined by records of treatment, adverse events which occurred during study treatment, and rate of response to therapy as assessed by the Patient Global Response Assessment (GRA). Primary outcome analysis compared response rates between treatment arms using Mantel-Haenszel methods. Results Twenty-three (49%) men and 24 (51%) women were randomized over a six month period. Twenty-four (51%) patients were randomized to GTM, 23 (49%) to MPT; 44 (94%) patients completed the study. Therapist adherence to the treatment protocols was excellent. The GRA response rate of 57% in the MPT group was significantly higher than the rate of 21% in the GTM treatment group (p=0.03). Conclusions The goals to judge feasibility of conducting a full-scale trial of physical therapy methods were met. The preliminary findings of a beneficial effect of MPT warrants further study.

The aims of this study were to map obesity prevention activity being implemented by government, non-government, and community-based organizations; to determine practitioner and policy-maker perceptions of the feasibility and effectiveness of a range of evidence-based obesity prevention strategies; and to determine practitioner and policy-maker perceptions of preferred settings for obesity prevention strategies. This study involved a cross-sectional survey of 304 public health practitioners and policy-makers from government, non-government, and community organizations across Victoria, Australia. Participants reported their organizations' current obesity prevention programs and policies, their own perceptions of the feasibility and effectiveness of strategies to prevent obesity and their preferred settings for obesity prevention. Thirty-nine percent had an obesity prevention policy, and 92% were implementing obesity prevention programs. The most common programs focused on education, skill-building, and increasing access to healthy eating/physical activity opportunities. School curriculum-based initiatives, social support for physical activity, and family-based programs were considered the most effective strategies, whereas curriculum-based initiatives, active after-school programs, and providing access to and information about physical activity facilities were deemed the most feasible strategies. Schools were generally perceived as the most preferred setting for obesity prevention. Many organizations had obesity prevention programs, but far fewer had obesity prevention policies. Current strategies and those considered feasible and effective are often mismatched with the empirical literature. Systems to ensure better alignment between researchers, practitioners, and policy-makers, and identifying effective methods of translating empirical evidence into practice and policy are required.

Objective The present study tested the feasibility of training peers with spinal cord injury (SCI) to learn brief action planning (BAP), an application of motivational interviewing principles, to promote physical activity to mentees with SCI. Method Thirteen peers with SCI attended a half-day BAP workshop. Using a one-arm, pre-, post-test design, feasibility to learn BAP was assessed in terms of peers' (1) BAP and motivational interviewing spirit competence; (2) training satisfaction; and (3) motivations to use BAP as assessed by measures of the theory of planned behavior constructs. Measures were taken at baseline, immediately post-training, and 1 month follow up. Results Following the training, participants' BAP and motivational interviewing competence significantly increased (P's < 0.05, d's > 2.27). Training satisfaction was very positive with all means falling above the scale midpoint. Participants' perceived behavioral control to use BAP increased from baseline to post (P < 0.05, d = 0.91) but was not maintained at follow up (P > 0.05). Conclusion Training peers with a SCI to learn to use BAP is feasible. Practical implications BAP is a tool that can be feasibly learned by peers to promote physical activity to their mentees.

To perform a systematic review of studies using remote physical activity monitoring in neurological diseases, highlighting advances and determining gaps. Studies were systematically identified in PubMed/MEDLINE, CINAHL and SCOPUS from January 2004 to December 2014 that monitored physical activity for ≥24 hours in adults with neurological diseases. Studies that measured only involuntary motor activity (tremor, seizures), energy expenditure or sleep were excluded. Feasibility, findings, and protocols were examined. 137 studies met inclusion criteria in multiple sclerosis (MS) (61 studies); stroke (41); Parkinson's Disease (PD) (20); dementia (11); traumatic brain injury (2) and ataxia (1). Physical activity levels measured by remote monitoring are consistently low in people with MS, stroke and dementia, and patterns of physical activity are altered in PD. In MS, decreased ambulatory activity assessed via remote monitoring is associated with greater disability and lower quality of life. In stroke, remote measures of upper limb function and ambulation are associated with functional recovery following rehabilitation and goal-directed interventions. In PD, remote monitoring may help to predict falls. In dementia, remote physical activity measures correlate with disease severity and can detect wandering. These studies show that remote physical activity monitoring is feasible in neurological diseases, including in people with moderate to severe neurological disability. Remote monitoring can be a psychometrically sound and responsive way to assess physical activity in neurological disease. Further research is needed to ensure these tools provide meaningful information in the context of specific neurological disorders and patterns of neurological disability.

Introduction Systematic reviews have identified the lack of intervention studies with young children to prevent obesity. This feasibility study examines the feasibility and acceptability of adapting the Nutrition and Physical Activity Self-Assessment for Child Care (NAP SACC) intervention in the UK to inform a full-scale trial. Methods and analysis A feasibility cluster randomised controlled trial in 12 nurseries in England, with 6 randomly assigned to the adapted NAP SACC UK intervention: nursery staff will receive training and support from an NAP SACC UK Partner to review the nursery environment (nutrition, physical activity, sedentary behaviours and oral health) and set goals for making changes. Parents will be invited to participate in a digital media-based home component to set goals for making changes in the home. As this is a feasibility study, the sample size was not based on a power calculation but will indicate the likely response rates and intracluster correlations. Measures will be assessed at baseline and 8–10 months later. We will estimate the recruitment rate of nurseries and children and adherence to the intervention and data. Nursery measurements will include the Environmental Policy Assessment and Observation score and the nursery staff's review of the nursery environment. Child measurements will include height and weight to calculate z-score body mass index (zBMI), accelerometer-determined minutes of moderate-to-vigorous physical activity per day and sedentary time, and diet using the Child and Diet Evaluation Tool. Questionnaires with nursery staff and parents will measure mediators. A process evaluation will assess fidelity of intervention delivery and views of participants. Ethics and dissemination Ethical approval for this study was given by Wales 3 NHS Research Ethics Committee. Findings will be made available through publication in peer-reviewed journals, at conferences and to participants via the University of Bristol website. Data will be available from the University of Bristol Research Data Repository. Trial registration number ISRCTN16287377. PMID:27053273

Measures will be assessed at baseline and 8-10 months later. We will estimate the recruitment rate of nurseries and children and adherence to the intervention and data. Nursery measurements will include the Environmental Policy Assessment and Observation score and the nursery staff's review of the nursery environment. Child measurements will include height and weight to calculate z-score body mass index (zBMI), accelerometer-determined minutes of moderate-to-vigorous physical activity per day and sedentary time, and diet using the Child and Diet Evaluation Tool. Questionnaires with nursery staff and parents will measure mediators. A process evaluation will assess fidelity of intervention delivery and views of participants. Ethical approval for this study was given by Wales 3 NHS Research Ethics Committee. Findings will be made available through publication in peer-reviewed journals, at conferences and to participants via the University of Bristol website. Data will be available from the University of Bristol Research Data Repository. ISRCTN16287377. Published by the BMJ Publishing Group Limited.

Background Advances in smartphones and the wide usage of social networking systems offer opportunities for the development of innovative interventions to promote physical activity. To that end, we developed a persuasive and social mHealth application designed to monitor and motivate users to walk more every day. Objective The objectives of this project were to conduct a focused review on the fundamental characteristics of mHealth for physical activity promotion, to develop an mHealth application that meets such characteristics, and to conduct a feasibility study to deploy the application in everyday life. Methods This project started as an analytical study to review the fundamental characteristics of the technologies used in physical activity monitoring and promotion. Then, it was followed by a technical development of the application. Next, a 4 week deployment was conducted where participants used the application as part of their daily life. A think-aloud method and in-depth semistructured interviews were conducted following the deployment. A qualitative description method was used to thematically analyze the interviews. Feasibility measures included, adherence to the program, user-system interactions, motivation to use, and experience with physical activity and online social interactions. Results There were seven fundamental characteristics of physical activity monitoring and promotion that were identified, which were then used as a foundation to develop the application. There were fourteen participants that enrolled in the application evaluation. The age range was from 24 to 45; body mass index ranged from 18.5 to 42.98, with 4 of the subjects falling into the category “obese”. Half of them were experienced with smartphones, and all were familiar with a social network system. There were thirteen participants that completed the study; one was excluded. Overall, participants gave high scores to almost all of the usability factors examined, with averages of 4.52 out of a 5.00 maximum. Over 29 days, participants used the application for a total of 119,380 minutes (average=7.57 hours/day/participant; SD 1.56). Conclusions Based on the fundamental characteristics, the application was successfully developed. The usability results suggest that the system is usable and user satisfaction was high. Deploying the application was shown to be feasible for the promotion of daily physical activity. PMID:25099928

Cardiovascular prevention is more effective if started early in life, but available interventions to promote healthy lifestyle habits among youth have been ineffective. Impulsivity in particular has proven to be an important barrier to the adoption of healthy behaviors in youth. Observational evidence suggests that mindfulness interventions may reduce impulsivity and improve diet and physical activity. We hypothesize that mindfulness training in adjunct to traditional health education will improve dietary habits and physical activity among teenagers by reducing impulsive behavior and improving planning skills. The Commit to Get Fit study is a pilot cluster randomized controlled trial examining the feasibility, acceptability and preliminary efficacy of school-based mindfulness training in adjunct to traditional health education for promotion of a healthy diet and physical activity among adolescents. Two schools in central Massachusetts (30 students per school) will be randomized to receive mindfulness training plus standard health education (HE-M) or an attention-control intervention plus standard health education (HE-AC). Assessments will be conducted at baseline, intervention completion (2 months), and 8 months. Primary outcomes are feasibility and acceptability. Secondary outcomes include physical activity, diet, impulsivity, mood, body mass index, and quality of life. This study will provide important information about feasibility and preliminary estimates of efficacy of a school-delivered mindfulness and health education intervention to promote healthy dietary and physical activity behaviors among adolescents. Our findings will provide important insights about the possible mechanisms by which mindfulness training may contribute to behavioral change and inform future research in this important area.

To explore the feasibility and acceptability of a new home-based exercise technology among older adults and to evaluate its efficacy on physical performance measures. Longitudinal clinical trial. Oak Hammock at the University of Florida, a nursing home located in Gainesville, Florida. Twelve pre-disabled older adults (≥75 years) living in a nursing home with a Short Physical Performance Battery (SPPB) score between 6 and 9 and no diagnosis of dementia. Thirty minutes of light intensity exercise (aerobic, strength and balance) two times per week for four weeks using a home-based physical activity technology called Jintronix. Feasibility and acceptability were assessed through a 9-item self-administered questionnaire and by exploring the percentage of quality of movements and time performing exercise which was calculated automatically by Jintronix technology. Physical performance measures were assessed through the SPPB score at baseline, after 4 weeks of intervention and after 3 months from the completion of the intervention. Twelve older adults (80.5±4.2 years old) performed light intensity exercise with Jintronix for a total of 51.9±7.9 minutes per week. Participants reached 87% score of quality of movements in strength and balance exercises, a global appreciation score of 91.7% and a global difficulty score of 36%. Compared to baseline, there was a significant improvement in SPPB score at the end of the intervention and at 3 months following the completion of the exercise program (0.67±0.98 and 1.08±0.99 respectively, p-value <0.05). Jintronix technology is feasible and acceptable among pre-disabled older adults without dementia living in nursing home and is beneficial in improving their physical performance.

Intervention development can be accelerated by using wearable sensors and ecological momentary assessment (EMA) to study how behaviors change within a person. The purpose of this study was to determine the feasibility and acceptability of a novel, intensive EMA method for assessing physiology, behavior, and psychosocial variables utilizing two objective sensors and a mobile application (app). Adolescents (n = 20) enrolled in a 20-day EMA protocol. Participants wore a physiological monitor and an accelerometer that measured sleep and physical activity and completed four surveys per day on an app. Participants provided approximately 81 % of the expected survey data. Participants were compliant to the wrist-worn accelerometer (75.3 %), which is a feasible measurement of physical activity/sleep (74.1 % complete data). The data capture (47.8 %) and compliance (70.28 %) with the physiological monitor were lower than other study variables. The findings support the use of an intensive assessment protocol to study real-time relationships between biopsychosocial variables and health behaviors.

An evaluation of NCRP report 151--radiation shielding design for radiotherapy facilities, and a feasibility study for 6 MV open-door treatments in an existing high-energy radiation therapy bunker

NASA Astrophysics Data System (ADS)

Kildea, John

This thesis describes a study of shielding design techniques used for radiation therapy facilities that employ megavoltage linear accelerators. Specifically, an evaluation of the shielding design formalism described in NCRP report 151 was undertaken and a feasibility study for open-door 6 MV radiation therapy treatments in existing 6 MV, 18 MV treatment rooms at the Montreal General Hospital (MGH) was conducted. To evaluate the shielding design formalism of NCRP 151, barrier-attenuated equivalent doses were measured for several of the treatment rooms at the MGH and compared with expectations from NCRP 151 calculations. It was found that, while the insight and recommendations of NCRP 151 are very valuable, its dose predictions are not always correct. As such, the NCRP 151 methodology is best used in conjunction with physical measurements. The feasibility study for 6 MV open-door treatments made use of the NCRP 151 formalism, together with physical measurements for realistic 6 MV workloads. The results suggest that, dosimetrically, 6 MV open door treatments are feasible. A conservative estimate for the increased dose at the door arising from such treatments is 0.1 mSv, with a 1/8 occupancy factor, as recommended in NCRP 151, included.

This study investigates the feasibility of a Latin dance program in older Latinos with mild cognitive impairment (MCI) via a feasibility mixed methods randomized controlled design. Spanish-speaking older Latinos (N = 21, 75.4 [6.3] years old, 16 females/5 males, 22.4 [2.8] Mini-Mental State Examination [MMSE] score) were randomized into a 16-week dance intervention (BAILAMOS) or wait-list control; the control group crossed over at week 17 and received the dance intervention. Feasibility was determined by assessing reach, retention, attendance, dance logs, and postintervention focus groups. Reach was 91.3% of people who were screened and eligible. Program retention was 95.2%. The dropout rate was 42.8% (n = 9), and attendance for all participants was 55.76%. The focus group data revealed 4 themes: enthusiasm for dance, positive aspects of BAILAMOS, unfavorable aspects of BAILAMOS, and physical well-being after BAILAMOS. In conclusion, older Latinos with MCI find Latin dance as an enjoyable and safe mode of physical activity.

Study Design A pilot double-blind randomized controlled trial (RCT). Background The effectiveness of physical therapy for femoroacetabular impingement syndrome (FAIS) is unknown. Objectives To determine the feasibility of an RCT investigating the effectiveness of a physical therapy intervention for FAIS. Methods Participants were 17 women and 7 men (mean ± SD age, 37 ± 8 years; body mass index, 25.4 ± 3.4 kg/m 2 ) with FAIS who received physical therapy interventions provided over 12 weeks. The FAIS-specific physical therapy group received personalized progressive strengthening and functional retraining. The control group received standardized stretching exercises. In addition, both groups received manual therapy, progressive physical activity, and education. The primary outcome was feasibility, including integrity of the protocol, recruitment and retention, outcome measures, randomization procedure, and sample-size estimate. Secondary outcomes included hip pain and function (international Hip Outcome Tool-33 [iHOT-33]) and hip muscle strength. Poststudy interviews were conducted to determine potential improvements for future studies. Results Twenty-four (100%) patients with known eligibility agreed to participate. Four patients (17%) were lost to follow-up. All participants and the tester remained blinded, and the control intervention was acceptable to participants. The between-group mean differences in change scores were 16 (95% confidence interval [CI]: -9, 38) for the iHOT-33 and 0.24 (95% CI: 0.02, 0.47) Nm/kg for hip adduction strength, favoring the FAIS-specific physical therapy group. Using an effect size of 0.61, between-group improvements for the iHOT-33 suggest that 144 participants are required for a full-scale RCT. Conclusion A full-scale RCT of physical therapy for FAIS is feasible. A FAIS-specific physical therapy program has the potential for a moderate to large positive effect on hip pain, function, and hip adductor strength. Level of Evidence Therapy, level 2b.

The aim was to assess feasibility of a 3 + 1 week inpatient rehabilitation program for cancer survivors, to explore characteristics of the attending participants and examine changes in work status, symptoms and functioning, level of fatigue, exercise and physical performance following rehabilitation. This was an open intervention study involving cancer survivors having completed primary cancer treatment. The multidisiplinary program consisted of physical training, patient education and group sessions. Participant were assessed at primary stay (T0), at follow-up stay 8-12 weeks later (T1), and six months after T1 (T2). Symptoms and functioning were assessed by the European Organization for Research and Treatment Core Quality-of-Life Questionnaire, physical fatigue by Fatigue Questionnaire, physical exercise by The Nord- Trøndelag Health Study Physical Activity Questionnaire and physical performance by aerobic capacity (VO(2max)), 30 second Sit-to-stand (STS) and Maximum Step Length (MSL). Linear mixed models were used in analyses. One hundred and thirty-four of 163 included participants (82%) completed both rehabilitation stays and returned questionaires at T2. The majority of completers were females (81%), breast cancer survivors (60%), highly educated and with mean age of 52.8 years (SD of 8.1). Participants had higher level of symptoms and fatigue and lower functioning at admission compared to a Norwegian reference population. However, they reported higher physical exercise level and 47% reported improved work status from T0 to T2. Symptoms and functioning, fatigue, physical exercise and physical performance improved significantly from T0 to T1 and were maintained at T2. The rehabilitation program was feasible and symptoms and functioning normalized following rehabilitation. The program mainly recruited well-educated breast cancer survivors, reporting relative high level of physical exercise. More focus should be put on recruiting and selecting those who need comprehensive inpatient rehabilitation and also compare the effects of inpatient with outpatient rehabilitation programs.

This pilot study aimed at investigating the effectiveness of lowering playground density on increasing children's physical activity and decreasing sedentary time. Also the feasibility of this intervention was tested. Data were collected in September and October 2012 in three Belgian schools in 187, 9-12 year old children. During the intervention, playground density was decreased by splitting up recesses and decreasing the number of children sharing the playground. A within-subject design was used. Children wore accelerometers during the study week. Three-level (class - participant - measurement (baseline or intervention)) linear regression models were used to determine intervention effects. After the intervention week the school principals filled out a questionnaire concerning the feasibility of the intervention. The available play space was 12.18 ± 4.19 m²/child at baseline and increased to 24.24 ± 8.51 m²/child during intervention. During the intervention sedentary time decreased (-0.58 min/recess; -3.21%/recess) and moderate-to-vigorous physical activity (+1.04 min/recess; +5.9%/recess) increased during recess and during the entire school day (sedentary time: -3.29%/school day; moderate-to-vigorous physical activity +1.16%/school day). All principals agreed that children enjoyed the intervention; but some difficulties were reported. Lowering playground density can be an effective intervention for decreasing children's sedentary time and increasing their physical activity levels during recess; especially in least active children.

Research has shown the efficacy of family-based behavioral interventions for overweight children, but a major difficulty is access to effective treatment programs. The objective of this study was to develop and test the initial feasibility and efficacy of a web-based family program for overweight 8- to 12-year-old children. A website was created using concepts from effective family-based behavioral programs and input from focus groups with overweight children, parents, and pediatricians. The website provided information about obesity and healthy lifestyles, assessment of dietary and physical activity habits, interactive dietary and physical activity games, and instruction in goal-setting and monitoring of goals. Children selected a dietary and physical activity goal and a daily step goal with pedometers. Feasibility and pilot testing over 4 weeks was conducted with 24 overweight children referred by a physician. Outcomes were z-BMI, healthy eating and physical activity, and intrinsic motivation and self-efficacy for weight control. Mean number of logins over the study period was 11.4 for the study sample. Eighteen families (75%) returned for the follow-up assessment. Pre-post analyses for these participants showed improvements in intrinsic motivation, (p=0.05), self-efficacy (p=0.025), physical activity (p=0.005), and healthy lifestyle behaviors (p=0.001). Comparisons between high and low users of the program indicated that high users reduced their BMI while low users increased their BMI over time (p=0.02); high users also improved their dietary intake relative to low users (p=0.04). Consumer satisfaction ratings were high. These pilot findings suggest this is a feasible approach for treatment of overweight children and that children who used the web program frequently improved their BMI and dietary intake.

Low back pain during pregnancy is common and associated with sick leave. Studies suggest that exercise may reduce low back pain during pregnancy. Before carrying out a randomised controlled trail with individual water exercise as intervention a qualitative feasibility study was done. To explore women's views and experiences of the acceptability and benefits of and possible barriers to the standardised individual unsupervised water exercise intervention. Eleven women were interviewed after participating in a water exercise intervention. Content analysis was used. Four main categories emerged: motivation to participate, attitudes towards the exercise programme, perception of benefits, and acceptability of supportive components. The women had a desire to stay physically active during pregnancy and found water exercise a suitable, type of exercise to perform during pregnancy. The intervention was experienced to have benefits on both their physical health and their mental well-being. Crowded swimming pools were perceived as the greatest barrier. It is feasible to perform a RCT using the described intervention. The intervention was accepted by the participants because it supported their desire to be physically active during pregnancy. The main barrier was crowded swimming pools and this issue must be addressed in a future RCT. Copyright © 2014 Elsevier B.V. All rights reserved.

For older people and people with a chronic disease, physical activity provides health benefits. Patients and healthcare professionals can use commercially available activity trackers to objectively monitor (alterations in) activity levels and patterns and to support physical activity. However, insight in the validity, reliability, and feasibility of these trackers in people with a chronic disease is needed. In this article, a study protocol is described in which the validity, reliability (part A), and feasibility from a patient and therapist's point of view (part B) of commercially available activity trackers in daily life and health care is investigated. In part A, a quantitative cross-sectional study, an activity protocol that simulates everyday life activities will be used to determine the validity and reliability of nine commercially available activity trackers. Video recordings will act as the gold standard. In part B, a qualitative participatory action research study will be performed to gain insight in the use of activity trackers in peoples' daily life and therapy settings. Objective feasibility of the activity trackers will be measured with questionnaires, and subjective feasibility (experiences) will be explored in a community of practice. Physical therapists ( n  = 8) will regularly meet during 6 months to learn from each other regarding the actual use of activity trackers in therapy. Therapists and patients ( n  = 48) will decide together which tracker will be used in therapy and for which purpose (e.g., monitoring, goal setting). Data from the therapist' and patients' experiences will be collected by interviews (individual and focus groups) and analyzed by a directed content analysis. At the time of submission, selection of activity trackers, development of the activity protocol, and the ethical approval process are finished. Data collection and data processing are ongoing. The relevance of the study as well as the advantages and disadvantages of several aspects of the chosen design are discussed. The results acquired from both study parts can be used to create decision aids that may assist therapists and people with a chronic disease in choosing a suitable activity tracker, and to facilitate use of these activity trackers in health care settings. Ethical approval has been obtained from two medical-ethical committees (nr. 15-N-109, 15-N-48 and MEC-15-07).

Physical activity levels are low amongst adolescent girls, and this population faces specific barriers to being active. Peer influences on health behaviours are important in adolescence, and peer-led interventions might hold promise to change behaviour. This paper describes the protocol for a feasibility cluster randomised controlled trial of Peer-Led physical Activity iNtervention for Adolescent girls (PLAN-A), a peer-led intervention aimed at increasing adolescent girls' physical activity levels. In addition, this paper describes an update that has been made to the protocol for the PLAN-A feasibility cluster randomised controlled trial. A two-arm cluster randomised feasibility trial will be conducted in six secondary schools (intervention n  = 4; control n  = 2) with year 8 (12-13 years old) girls. The intervention will operate at a year group level and consist of year 8 girls nominating influential peers within their year group to become peer supporters. Approximately 15% of the cohort will receive 3 days of training about physical activity and interpersonal communication skills. Peer supporters will then informally diffuse messages about physical activity amongst their friends for 10 weeks. Data will be collected at baseline (time 0 (T0)), immediately after the intervention (time 1 (T1)) and 12 months after baseline measures (time 2 (T2)). In this feasibility trial, the primary interest is in the recruitment of schools and participants (both year 8 girls and peer supporters), delivery and receipt of the intervention, data provision rates and identifying the cost categories for future economic analysis. Physical activity will be assessed using 7-day accelerometry, with the likely primary outcome in a fully powered trial being daily minutes of moderate-to-vigorous physical activity. Participants will also complete psychosocial questionnaires at each time point: assessing motivation, self-esteem and peer physical activity norms. Data analysis will be largely descriptive and focus on recruitment, attendance and data provision rates. The findings will inform the sample size required for a definitive trial. A detailed process evaluation using qualitative and quantitative methods will be conducted with a variety of stakeholders (i.e. pupils, parents, teachers and peer-supporter trainers) to identify areas of success and necessary improvements prior to proceeding to a definitive trial. The study will provide the information necessary to design a fully powered trial should PLAN-A demonstrate evidence of promise. This paper describes an update to the protocol for the PLAN-A feasibility cluster randomised controlled trial related to the data-linkage component. ISRCTN12543546.

Objective We evaluated the feasibility of a trial of Wii interactive video gaming, and its potential efficacy at improving cognitive functioning compared to health education, in a community sample of older adults with neuropsychologically defined mild cognitive impairment (MCI). Methods Twenty older adults were equally randomized to either group-based interactive video gaming or health education for 90 minutes each week for 24 weeks. Although the primary outcomes were related to study feasibility, we also explored the effect of the intervention on neuropsychological performance and other secondary outcomes. Results All 20 participants completed the intervention, and 18 attended at least 80% of the sessions. The majority (80%) of participants were “very much” satisfied with the intervention. Bowling was enjoyed by the most participants, and was also the rated highest among the games for mental, social and physical stimulation. We observed medium effect sizes for cognitive and physical functioning in favor of the interactive video gaming condition, but these effects were not statistically significant in this small sample. Conclusion Interactive video gaming is feasible for older adults with MCI and medium effects sizes in favor of the Wii group warrant a larger efficacy trial. PMID:24452845

The purpose of this study is describe the initial feasibility, reliability, and validity of an instrument to measure physical activity in preschoolers using direct observation. The System for Observing Fitness Instruction Time for Preschoolers was developed and tested among 3- to 6-year-old children over fall 2008 for feasibility and reliability (Phase I, n=67) and in fall 2009 for concurrent validity (Phase II, n=27). Phase I showed that preschoolers spent >75% of their active time at preschool in light physical activity. The mean inter-observer agreements scores were ≥.75 for physical activity level and type. Correlation coefficients, measuring construct validity between the lesson context and physical activity types with and with the activity levels, were moderately strong. Phase II showed moderately strong correlations ranging from .50 to .54 between the System for Observing Fitness Instruction Time for Preschoolers and Actigraph accelerometers for physical activity levels. The System for Observing Fitness Instruction Time for Preschoolers shows promising initial results as a new method for measuring physical activity among preschoolers. PMID:22485071

Few studies have examined the effectiveness of community-based self-management interventions in older adults with type 2 diabetes mellitus (T2DM) and multiple chronic conditions (MCC). The objectives of this study were to examine the feasibility of implementation in practice (primary) and the feasibility of study methods and potential effectiveness (secondary) of the Aging, Community and Health-Community Partnership Program, a new 6-month interprofessional, nurse-led program to promote diabetes self-management in older adults (>65 years) with T2DM and MCC. This study used a prospective one-group pre-test/post-test design. Participants were recruited from a specialized diabetes clinic. They received a median of three in-home/clinic visits by certified diabetes educators (CDEs) and attended a median of three group wellness sessions provided by the CDEs in partnership with a community-based seniors' association. The primary outcome was the feasibility of the program (acceptability, fidelity, implementation barriers/facilitators). Secondary outcomes included the feasibility of the study methods (recruitment/retention rates and procedures, eligibility criteria, data collection and analysis methods) and potential effectiveness of the program based on 6-month changes in self-reported outcomes including self-management behavior (diet, exercise, self-monitoring), health status (quality of life, mental health), and costs of service use. Analysis of feasibility outcomes was primarily based on descriptive statistics. The potential effectiveness of the program was explored using different tests, with the results expressed using descriptive statistics and effect estimates (95 % confidence intervals). In total, 45 (88 %) of 51 eligible persons consented to participate. Of these, 37 (82 %) completed the 6-month follow-up. Participants and providers viewed the program as acceptable and feasible. Participants had a higher SF-12 physical component summary score at 6 months compared with baseline (mean score difference 3.0, 95 % CI 0.2-5.8). Median costs for diabetes care increased over 6 months (reflecting inclusion of program costs), while other service costs either decreased or remained unchanged. This study offers preliminary evidence that the program was feasible to deliver and acceptable to participants and providers. Initial results suggest that the program may improve physical functioning. A randomized controlled trial is feasible, with some adaptations to the program and study methods that were identified from this feasibility study. Clinicaltrials.gov identifier: NCT01880476.

Objective To assess feasibility and acceptability of a multifaceted, culturally appropriate intervention for preventing obesity in South Asian children, and to obtain data to inform sample size for a definitive trial. Design Phase II feasibility study of a complex intervention. Setting 8 primary schools in inner city Birmingham, UK, within populations that are predominantly South Asian. Participants 1090 children aged 6–8 years took part in the intervention. 571 (85.9% from South Asian background) underwent baseline measures. 85.5% (n=488) were followed up 2 years later. Interventions The 1-year intervention consisted of school-based and family-based activities, targeting dietary and physical activity behaviours. The intervention was modified and refined throughout the period of delivery. Main outcome measures Acceptability and feasibility of the intervention and of measurements required to assess outcomes in a definitive trial. The difference in body mass index (BMI) z-score between arms was used to inform sample size calculations for a definitive trial. Results Some intervention components (increasing school physical activity opportunities, family cooking skills workshops, signposting of local leisure facilities and attending day event at a football club) were feasible and acceptable. Other components were acceptable, but not feasible. Promoting walking groups was neither acceptable nor feasible. At follow-up, children in the intervention compared with the control group were less likely to be obese (OR 0.41; 0.19 to 0.89), and had lower adjusted BMI z-score (−0.15 kg/m2; 95% CI −0.27 to −0.03). Conclusions The feasibility study informed components for an intervention programme. The favourable direction of outcome for weight status in the intervention group supports the need for a definitive trial. A cluster randomised controlled trial is now underway to assess the clinical and cost-effectiveness of the intervention. Trial registration number ISRCTN51016370. PMID:24722198

Motivation towards an exercise program is higher in a small group setting in comparison to individual therapy. Due to attentional problems, group exercises are difficult for people with Alzheimer disease (AD). This study evaluates the feasibility of a music-supported video-based group exercise program in older adults suffering from AD. Five participants with moderate AD were recruited from a nursing home. A progressive physical exercise program using a video-based training with musical accompaniment was performed and digitally recorded to investigate the adherence and performed accuracy of the exercises. The overall participation during the exercises was 84.1%. The quality of the performance was for all exercises above the cut-off scores. A music-supported video-based group exercise program is feasible in persons with AD. The participants were motivated and the expectations towards the program increased over time. Music seemed an important factor for attention in participants with AD.

Low physical activity level is associated with poor prognosis in patients with colorectal cancer (CRC). To increase physical activity, technology-based platforms are emerging and provide intriguing opportunities to prescribe and monitor active lifestyle interventions. The "Interval Walking in Colorectal Cancer"(I-WALK-CRC) study explores the feasibility and efficacy a home-based interval-walking intervention delivered by a smart-phone application in order to improve cardio-metabolic health profile among CRC survivors. The aim of the present report is to describe the design, methods and recruitment results of the I-WALK-CRC study.Methods/Results: The I-WALK-CRC study is a randomized controlled trial designed to evaluate the feasibility and efficacy of a home-based interval walking intervention compared to a waiting-list control group for physiological and patient-reported outcomes. Patients who had completed surgery for local stage disease and patients who had completed surgery and any adjuvant chemotherapy for locally advanced stage disease were eligible for inclusion. Between October 1st , 2015, and February 1st , 2017, 136 inquiries were recorded; 83 patients were eligible for enrollment, and 42 patients accepted participation. Age and employment status were associated with participation, as participants were significantly younger (60.5 vs 70.8 years, P < 0.001) and more likely to be working (OR 5.04; 95%CI 1.96-12.98, P < 0.001) than non-participants. In the present study, recruitment of CRC survivors was feasible but we aim to better the recruitment rate in future studies. Further, the study clearly favored younger participants. The I-WALK-CRC study will provide important information regarding feasibility and efficacy of a home-based walking exercise program in CRC survivors.

Objective To perform a systematic review of studies using remote physical activity monitoring in neurological diseases, highlighting advances and determining gaps. Methods Studies were systematically identified in PubMed/MEDLINE, CINAHL and SCOPUS from January 2004 to December 2014 that monitored physical activity for ≥24 hours in adults with neurological diseases. Studies that measured only involuntary motor activity (tremor, seizures), energy expenditure or sleep were excluded. Feasibility, findings, and protocols were examined. Results 137 studies met inclusion criteria in multiple sclerosis (MS) (61 studies); stroke (41); Parkinson's Disease (PD) (20); dementia (11); traumatic brain injury (2) and ataxia (1). Physical activity levels measured by remote monitoring are consistently low in people with MS, stroke and dementia, and patterns of physical activity are altered in PD. In MS, decreased ambulatory activity assessed via remote monitoring is associated with greater disability and lower quality of life. In stroke, remote measures of upper limb function and ambulation are associated with functional recovery following rehabilitation and goal-directed interventions. In PD, remote monitoring may help to predict falls. In dementia, remote physical activity measures correlate with disease severity and can detect wandering. Conclusions These studies show that remote physical activity monitoring is feasible in neurological diseases, including in people with moderate to severe neurological disability. Remote monitoring can be a psychometrically sound and responsive way to assess physical activity in neurological disease. Further research is needed to ensure these tools provide meaningful information in the context of specific neurological disorders and patterns of neurological disability. PMID:27124611

Few studies have examined exercise as a substance use disorder treatment. This pilot study investigated the feasibility and acceptability of an exercise intervention comprising the Wii Fit Plus™ and of a time-and-attention sedentary control comprising Wii™ videogames. We also explored their impact on physical activity levels, substance use, and psychological wellness. Twenty-nine methadone-maintained patients enrolled in an 8-week trial were randomly assigned to either Active Game Play (Wii Fit Plus™ videogames involving physical exertion) or Sedentary Game Play (Wii™ videogames played while sitting). Participants had high satisfaction and study completion rates. Active Game Play participants reported greater physical activity outside the intervention than Sedentary Game Play participants despite no such differences at baseline. Substance use decreased and stress and optimism improved in both conditions. Active Game Play is a feasible and acceptable exercise intervention, and Sedentary Game Play is a promising time-and-attention control. Further investigations of these interventions are warranted.

The aim of this study was to explore the application of the IROMEC (Interactive social RObotic Mediators as Companions) robot to support play for children with severe physical disabilities in rehabilitation and special education. Within a 2-month pilot study, physically disabled children with a developmental age between 2 and 8 years participated in sessions with the robot. A combination of qualitative and quantitative outcome measures was used to collect data on aspects of feasibility, usability, barriers for the child as well as the therapist and an indication of the effects on playfulness and the achievement of therapeutic and educational goals. A total of 11 children participated in this study (four boys, seven girls). Individually Prioritized Problem Assessment scores indicated a positive effect of the IROMEC robot on the achievement of goals for the children. Professionals did observe meaningful application possibilities, but the lacking adaptability, expandability and technical stability of the robot platform make application in daily care practice impossible. The application of a robot like IROMEC for children with severe physical disabilities seems to be positive and worthwhile, but usability and feasibility aspects are crucial for success.

Background The majority of young people do not meet the recommendations on physical activity for health. New innovative ways to motivate young people to adopt a physically active lifestyle are needed. Objective The study aimed to study the feasibility of an automated, gamified, tailored Web-based mobile service aimed at physical and social activation among young men. Methods A population-based sample of 496 young men (mean age 17.8 years [standard deviation 0.6]) participated in a 6-month randomized controlled trial (MOPO study). Participants were randomized to an intervention (n=250) and a control group (n=246). The intervention group was given a wrist-worn physical activity monitor (Polar Active) with physical activity feedback and access to a gamified Web-based mobile service, providing fitness guidelines, tailored health information, advice of youth services, social networking, and feedback on physical activity. Through the trial, the physical activity of the men in the control group was measured continuously with an otherwise similar monitor but providing only the time of day and no feedback. The primary outcome was the feasibility of the service based on log data and questionnaires. Among completers, we also analyzed the change in anthropometry and fitness between baseline and 6 months and the change over time in weekly time spent in moderate to vigorous physical activity. Results Mobile service users considered the various functionalities related to physical activity important. However, compliance of the service was limited, with 161 (64.4%, 161/250) participants visiting the service, 118 (47.2%, 118/250) logging in more than once, and 41 (16.4%, 41/250) more than 5 times. Baseline sedentary time was higher in those who uploaded physical activity data until the end of the trial (P=.02). A total of 187 (74.8%, 187/250) participants in the intervention and 167 (67.9%, 167/246) in the control group participated in the final measurements. There were no differences in the change in anthropometry and fitness from baseline between the groups, whereas waist circumference was reduced in the most inactive men within the intervention group (P=.01). Among completers with valid physical activity data (n=167), there was a borderline difference in the change in mean daily time spent in moderate to vigorous physical activity between the groups (11.9 min vs −9.1 min, P=.055, linear mixed model). Within the intervention group (n=87), baseline vigorous physical activity was inversely associated with change in moderate to vigorous physical activity during the trial (R=−.382, P=.01). Conclusions The various functionalities related to physical activity of the gamified tailored mobile service were considered important. However, the compliance was limited. Within the current setup, the mobile service had no effect on anthropometry or fitness, except reduced waist circumference in the most inactive men. Among completers with valid physical activity data, the trial had a borderline positive effect on moderate to vigorous physical activity. Further development is needed to improve the feasibility and adherence of an integrated multifunctional service.

Effectiveness and feasibility of lowering playground density during recess to promote physical activity and decrease sedentary time at primary school

PubMed Central

2013-01-01

Background This pilot study aimed at investigating the effectiveness of lowering playground density on increasing children’s physical activity and decreasing sedentary time. Also the feasibility of this intervention was tested. Methods Data were collected in September and October 2012 in three Belgian schools in 187, 9–12 year old children. During the intervention, playground density was decreased by splitting up recesses and decreasing the number of children sharing the playground. A within-subject design was used. Children wore accelerometers during the study week. Three-level (class – participant - measurement (baseline or intervention)) linear regression models were used to determine intervention effects. After the intervention week the school principals filled out a questionnaire concerning the feasibility of the intervention. Results The available play space was 12.18 ± 4.19 m2/child at baseline and increased to 24.24 ± 8.51 m2/child during intervention. During the intervention sedentary time decreased (−0.58 min/recess; -3.21%/recess) and moderate-to-vigorous physical activity (+1.04 min/recess; +5.9%/recess) increased during recess and during the entire school day (sedentary time: -3.29%/school day; moderate-to-vigorous physical activity +1.16%/school day). All principals agreed that children enjoyed the intervention; but some difficulties were reported. Conclusions Lowering playground density can be an effective intervention for decreasing children’s sedentary time and increasing their physical activity levels during recess; especially in least active children.

Long-term engagement in exercise and physical activity mitigates the progression of disability and increases quality of life in people with Parkinson disease (PD). Despite this, the vast majority of individuals with PD are sedentary. There is a critical need for a feasible, safe, acceptable, and effective method to assist those with PD to engage in active lifestyles. Peer coaching through mobile health (mHealth) may be a viable approach. The purpose of this study was to develop a PD-specific peer coach training program and a remote peer-mentored walking program using mHealth technology with the goal of increasing physical activity in persons with PD. We set out to examine the feasibility, safety, and acceptability of the programs along with preliminary evidence of individual-level changes in walking activity, self-efficacy, and disability in the peer mentees. A peer coach training program and a remote peer-mentored walking program using mHealth was developed and tested in 10 individuals with PD. We matched physically active persons with PD (peer coaches) with sedentary persons with PD (peer mentees), resulting in 5 dyads. Using both Web-based and in-person delivery methods, we trained the peer coaches in basic knowledge of PD, exercise, active listening, and motivational interviewing. Peer coaches and mentees wore FitBit Zip activity trackers and participated in daily walking over 8 weeks. Peer dyads interacted daily via the FitBit friends mobile app and weekly via telephone calls. Feasibility was determined by examining recruitment, participation, and retention rates. Safety was assessed by monitoring adverse events during the study period. Acceptability was assessed via satisfaction surveys. Individual-level changes in physical activity were examined relative to clinically important differences. Four out of the 5 peer pairs used the FitBit activity tracker and friends function without difficulty. A total of 4 of the 5 pairs completed the 8 weekly phone conversations. There were no adverse events over the course of the study. All peer coaches were "satisfied" or "very satisfied" with the training program, and all participants were "satisfied" or "very satisfied" with the peer-mentored walking program. All participants would recommend this program to others with PD. Increases in average steps per day exceeding the clinically important difference occurred in 4 out of the 5 mentees. Remote peer coaching using mHealth is feasible, safe, and acceptable for persons with PD. Peer coaching using mHealth technology may be a viable method to increase physical activity in individuals with PD. Larger controlled trials are necessary to examine the effectiveness of this approach. ©Cristina Colón-Semenza, Nancy K Latham, Lisa M Quintiliani, Terry D Ellis.

2017-12-01

The construction of a shale rock physics model and the selection of an appropriate brittleness index ( BI) are two significant steps that can influence the accuracy of brittleness prediction. On one hand, the existing models of kerogen-rich shale are controversial, so a reasonable rock physics model needs to be built. On the other hand, several types of equations already exist for predicting the BI whose feasibility needs to be carefully considered. This study constructed a kerogen-rich rock physics model by performing the selfconsistent approximation and the differential effective medium theory to model intercoupled clay and kerogen mixtures. The feasibility of our model was confirmed by comparison with classical models, showing better accuracy. Templates were constructed based on our model to link physical properties and the BI. Different equations for the BI had different sensitivities, making them suitable for different types of formations. Equations based on Young's Modulus were sensitive to variations in lithology, while those using Lame's Coefficients were sensitive to porosity and pore fluids. Physical information must be considered to improve brittleness prediction.

Therefore, this study aimed to examine the feasibility and efficacy of the 6-week home-based exercise program on the level of physical activity and physical fitness in stage II to III colorectal cancer survivors. Seventy-two stage II to III colorectal cancer survivors were randomly assigned to either a home-based exercise (n = 38) or usual care (n = 34) group for 6 weeks. The goal of the home-based exercise program was to increase the level of exercise to 18 metabolic equivalent task hours per week. The primary and the secondary outcomes of this study were physical activity level and physical fitness, respectively. A total of 57 participants (79.2%) completed the trial. Intention-to-treat analysis indicated that moderate physical activity level increased significantly by 269.4 ± 260.6 minutes per week in the exercise group (mean between-group difference, 254.6 minutes; 95% confidence interval, 172.7-434.7; p < 0.001). Physical fitness measured by using the step test (-3.9 vs. 2.6, p = 0.012) and push-up test (3.0 vs. -1.2, p = 0.012) also improved significantly in the exercise group compared to the control group. The 6-week home-based mixed aerobic and resistance exercise program was feasible and effective for increasing physical activity level and physical fitness in stage II to III colorectal cancer survivors.

The aim of our feasibility study was to examine the acceptability and utility of "Dance Dance Revolution" (DDR) (Konami of America, Redwood City, CA)) to increase physical fitness in 8-11-year-old black and Hispanic youth. Twenty-eight 4(th) and 5(th) grade children attending an afterschool program participated. Outcomes included physical activity, physical fitness, use of home DDR, survey of safety and acceptability, anthropometrics, and fasting metabolic profile measured at baseline, 12 weeks, and 30 weeks. At 12 weeks, physical fitness (maximum O2 uptake [VO2max]) increased by 4.9±9.9 percent and was sustained through 30 weeks, when the VO2max was 105.0±9.9 percent (range, 93.0-133.9 percent) of baseline values. Absolute VO2max increased by 2.97±4.99 mL/kg/minute (95% confidence interval 0.75-5.19, P=0.013). Participants maintained an average of 1.12 hours/day of increased movement to music. Trends suggested increased total moderate-vigorous physical activity, decreased light activity, and a modest increase in sedentary screen time. There were no significant changes in body mass index, fasting lipids, or glucose. Participants and parents approved of the activity. DDR appears feasible and acceptable to minority youth. DDR may increase moderate-vigorous physical activity and improve physical fitness in at-risk populations.

Fear-avoidance beliefs in older adults with chronic low back pain (CLBP) can lead to disability. Graded exposure-based active physical therapy could be an option to enhance physical ability in older patients with CLBP. The purpose of this study was to develop a standardized graded exposure treatment according to the fear-avoidance model of musculoskeletal pain for older patients with CLBP and to examine its effectiveness and feasibility in the German health care system. The study represents a phase I/phase II trial of a complex intervention. Taking a first step into the hierarchy of growing empirical evidence, a prospective 1-factor observational study was conducted with repeated measurements 1 week before and within 2 weeks after the intervention. Three physical therapists, who completed an introductory workshop, provided the treatment in the form of individual therapies. Sixteen participants 65 years or older with CLBP and perceived physical limitations were recruited. Four patient-reported outcome measures and semistructured interviews were conducted. The primary outcome was physical ability measured with the Hanover Functional Ability Questionnaire. Secondary outcomes were the numerical pain rating scale, and an age-specific and adapted 11-item short-form of the Patient Anxiety Symptom Scale, the KVS-D 65+, which quantified catastrophizing and avoidance beliefs. Fear of falling was measured with the Falls Efficacy Scale-International. For the analysis, Wilcoxon signed-rank test for paired samples and an α level of .05 were chosen. For the qualitative evaluation, semistructured interviews were conducted with the patients and physical therapists explored indicators of feasibility such as demands, acceptability, satisfaction, adaptation needs, and implementation. For content analysis, codes were primarily derived deductively and complemented by inductively derived new themes. A significant increase in physical ability after the treatment was observed with an effect size (ES) of 0.95 (P = .008). With regard to secondary outcomes, there was a statistically significant decrease in pain intensity (P = .029) and a reduction in catastrophizing (ES = 0.91; P = .021) and avoidance beliefs (ES = 1.37; P = .001). The interviews revealed good acceptance and satisfaction of the treatment by the patients and physical therapists. On the whole, the treatment appears effective and feasible. Apart from the benefits achieved by the participants, the study provides a basis for designing future studies at a higher level of evidence.

Abstract Purpose To evaluate the feasibility of regional physical therapy networks including continuing education in rheumatology. The aim of these networks was to improve care provided by primary care physical therapists by improving specific knowledge, technical and communicative skills and the collaboration with rheumatologists. Methods In two regions in The Netherlands continuing education (CE) programmes, consisting of a 5-day postgraduate training course followed by bimonthly workshops and teaching practices, were organised simultaneously. Network activities included consultations, newsletters and the development of a communication guideline. Endpoint measures included the participation rate, compliance, quality of the CE programme, teaching practices, knowledge, network activities, communication, number of patients treated and patient satisfaction. Results Sixty-three physical therapists out of 193 practices (33%) participated in the project. They all completed the education programmes and were formally registered. All evaluations of the education programmes showed positive scores. Knowledge scores increased significantly directly after the training course and at 18 months. A draft guideline on communication between physical therapists and rheumatologists was developed, and 4 newsletters were distributed. A substantial proportion of physical therapists and rheumatologists reported improved communication at 18 months. The mean number of patients treated by physical therapists participating in the networks increased significantly. Patients' satisfaction scores within the networks were significantly higher than those from outside the networks at 18 months. Conclusions Setting up a system of networks for continuing education for physical therapists regarding the treatment of patients with rheumatic diseases is feasible. Further research will focus on the effectiveness of the system and its implementation on a larger scale. PMID:16773150

Major depressive disorder is often comorbid with diabetes and associated with worse glycemic control. Exercise improves glycemic control and depression, and thus could be a parsimonious intervention for patients with comorbid diabetes and major depression. Because patients with diabetes and comorbid depression are often sedentary and lack motivation to exercise, we developed a group exercise intervention that integrates strategies from behavioral activation therapy for depression to increase motivation for and enjoyment of exercise. We conducted a 6-month pilot randomized controlled trial to test the feasibility of the behavioral activation exercise intervention (EX) for women with diabetes and depression. Of the 715 individuals who contacted us about the study, 29 participants were randomized to the EX condition or an enhanced usual care condition (EUC), which represents 4.1% of participants who initially contacted us. Inclusion criteria made recruitment challenging and limits the feasibility of recruiting women with diabetes and depression for a larger trial of the intervention. Retention was 96.5% and 86.2% at 3 and 6 months. Participants reported high treatment acceptability; use of behavioral activation strategies and exercise class attendance was acceptable. No condition differences were observed for glycemic control, depressive symptoms, and physical activity, though depressive symptoms and self-reported physical activity improved over time. Compared to participants in the EUC condition, participants in the EX condition reported greater exercise enjoyment and no increase in avoidance behavior over time. Using behavioral activation strategies to increase exercise is feasible in a group exercise setting. However, whether these strategies can be delivered in a less intensive manner to a broader population of sedentary adults, for greater initiation and maintenance of physical activity, deserves further study.

Cancer cachexia is a syndrome of weight loss (including muscle and fat), anorexia, and decreased physical function. It has been suggested that the optimal treatment for cachexia should be a multimodal intervention. The primary aim of this study was to examine the feasibility and safety of a multimodal intervention (n-3 polyunsaturated fatty acid nutritional supplements, exercise, and anti-inflammatory medication: celecoxib) for cancer cachexia in patients with incurable lung or pancreatic cancer, undergoing chemotherapy. Patients receiving two cycles of standard chemotherapy were randomized to either the multimodal cachexia intervention or standard care. Primary outcome measures were feasibility assessed by recruitment, attrition, and compliance with intervention (>50% of components in >50% of patients). Key secondary outcomes were change in weight, muscle mass, physical activity, safety, and survival. Three hundred and ninety-nine were screened resulting in 46 patients recruited (11.5%). Twenty five patients were randomized to the treatment and 21 as controls. Forty-one completed the study (attrition rate 11%). Compliance to the individual components of the intervention was 76% for celecoxib, 60% for exercise, and 48% for nutritional supplements. As expected from the sample size, there was no statistically significant effect on physical activity or muscle mass. There were no intervention-related Serious Adverse Events and survival was similar between the groups. A multimodal cachexia intervention is feasible and safe in patients with incurable lung or pancreatic cancer; however, compliance to nutritional supplements was suboptimal. A phase III study is now underway to assess fully the effect of the intervention. © 2017 The Authors.

Introduction Physical activity, healthy eating and maintaining a healthy weight are associated with reduced risk of cardiovascular disease, type 2 diabetes and cancer and with improved mental health. Despite these benefits, many men do not meet recommended physical activity guidelines and have poor eating behaviours. Many health promotion programmes hold little appeal to men and consequently fail to influence men’s health practices. HAT TRICK was designed as a 12-week face-to-face, gender-sensitised intervention for overweight and inactive men focusing on physical activity, healthy eating and social connectedness and was delivered in collaboration with a major junior Canadian ice hockey team (age range 16–20 years). The programme was implemented and evaluated to assess its feasibility. This article describes the intervention design and study protocol of HAT TRICK. Methods and analysis HAT TRICK participants (n=60) were men age 35 years, residing in the Okanagan Region of British Columbia, who accumulate 150 min of moderate to vigorous physical activity a week, with a body mass index of >25 kg/m2 and a pant waist size of >38’. Each 90 min weekly session included targeted health education and theory-guided behavioural change techniques, as well as a progressive (ie, an increase in duration and intensity) group physical activity component. Outcome measures were collected at baseline, 12 weeks and 9 months and included the following: objectively measured anthropometrics, blood pressure, heart rate, physical activity and sedentary behaviour, as well as self-reported physical activity, sedentary behaviour, diet, smoking, alcohol consumption, sleep habits, risk of depression, health-related quality of life and social connectedness. Programme feasibility data (eg, recruitment, satisfaction, adherence, content delivery) were assessed at 12 weeks via interviews and self-report. Ethics and dissemination Ethical approval was obtained from the University of British Columbia Okanagan Behavioural Research Ethics Board (reference no H1600736). Study findings will be disseminated through academic meetings, peer-reviewed publication, web-based podcasts, social media, plain language summaries and co-delivered community presentations.

Online social networks present wide-reaching and flexible platforms through which to deliver health interventions to targeted populations. This study used a social marketing approach to explore teenage girls' perceptions of physical activity and the potential use of online social networks to receive a physical activity intervention. Six focus groups were conducted with 19 Australian teenage girls (ages 13 to 18 years) with varying levels of physical activity and socioeconomic status. A semi-structured format was used, with groups discussion transcribed verbatim. Content analysis identified emergent themes, with triangulation and memos used to ensure accuracy. Physical activity was most appealing when it emphasised sport, exercise and fitness, along with opportunities for socialisation with friends and self-improvement. Participants were receptive to delivery of a physical activity intervention via online social networks, with Facebook the most widely reported site. Participants commonly accessed online social networks via mobile devices and particularly smartphones. Undesirable features included promotion of physical activity in terms of walking; use of cartoon imagery; use of humour; and promotion of the intervention via schools, each of which were considered "uncool". Participants noted that their parents were likely to be supportive of them using an online social networking physical activity intervention, particularly if not promoted as a weight loss intervention. This study identified key features likely to increase the feasibility and retention of an online social networking physical activity intervention for teenage girls. Guidelines for the design of interventions for teenage girls are provided for future applications.

We evaluated the feasibility of a trial of Wii interactive video gaming, and its potential efficacy at improving cognitive functioning compared with health education, in a community sample of older adults with neuropsychologically defined mild cognitive impairment. Twenty older adults were equally randomized to either group-based interactive video gaming or health education for 90 min each week for 24 weeks. Although the primary outcomes were related to study feasibility, we also explored the effect of the intervention on neuropsychological performance and other secondary outcomes. All 20 participants completed the intervention, and 18 attended at least 80% of the sessions. The majority (80%) of participants were "very much" satisfied with the intervention. Bowling was enjoyed by the most participants and was also rated the highest among the games for mental, social, and physical stimulation. We observed medium effect sizes for cognitive and physical functioning in favor of the interactive video gaming condition, but these effects were not statistically significant in this small sample. Interactive video gaming is feasible for older adults with mild cognitive impairment, and medium effect sizes in favor of the Wii group warrant a larger efficacy trial.

We examined the feasibility of a combined aerobic and strength training program in institutionalized dementia patients and studied the effects on cognitive and physical function. Thirty-three patients with dementia, recruited from one nursing home, participated in this non-randomized pilot study (25 women; age = 85.2±4.9 years; Mini Mental State Examination = 16.8±4.0). In phase 1 of the study, seventeen patients in the Exercise group (EG) received a combined aerobic and strength training program for six weeks, five times per week, 30 minutes per session, in an individually supervised format and successfully concluded the pre and posttests. In phase 2 of the study, sixteen patients in the Social group (SG) received social visits at the same frequency, duration, and format and successfully concluded the pre and posttests. Indices of feasibility showed that the recruitment and adherence rate, respectively were 46.2% and 86.3%. All EG patients completed the exercise program according to protocol without adverse events. After the six-week program, no significant differences on cognitive function tests were found between the EG and SG. There was a moderate effect size in favor for the EG for the Visual Memory Span Forward; a visual attention test. There were significant differences between groups in favor for the EG with moderate to large effects for the physical tests Walking Speed (p = .003), Six-Minute Walk Test (p = .031), and isometric quadriceps strength (p = .012). The present pilot study showed that it is feasible to conduct a combined aerobic and strength training program in institutionalized patients with dementia. The selective cognitive visual attention improvements and more robust changes in motor function in favor of EG vs. SG could serve as a basis for large randomized clinical trials. trialregister.nl 1230.

To investigate the feasibility and impact on BMI and physical fitness of an intervention for obese and inactive children, based on physical activity and carried out in primary health care. A prospective, longitudinal one-year follow-up study. The community of Kristiansand, Norway (80 000 inhabitants). A 40-week structured intervention based on physical training with some lifestyle advice for the obese child and one parent. Subjects. A total of 62 physically inactive children aged 6-14 years with iso-BMI ≥ 30 kg/m². Body mass index (BMI), maximum oxygen uptake, and physical fitness in tests of running, jumping, throwing, and climbing assessed at baseline and after six and 12 months as well as number of dropouts and predicting factors. A total of 49 out of 62 children completed the first six months and 37 children completed 12 months. Dropout rate was higher when parents reported being physically inactive at baseline or avoided physical participation in the intervention. The children's maximum oxygen uptake increased significantly after 12 months from 27.0 to 32.0 ml/kg/min (means), as did physical fitness (endurance, speed, agility, coordination, balance, strength) and BMI was significantly reduced. This one-year activity-based intervention for obese and inactive children performed in primary health care succeeded by increasing cardiovascular capacity and physical fitness combined with reduced BMI in those who completed. Dropout was substantial and depended on the attendance and compliance with physical activity by the parents.

Nursing home institutionalization tends to exacerbate loss of functioning. Examine the feasibility and the effect of a psychomotor intervention-a multimodal exercise program promoting simultaneous cognitive and motor stimulation-on the executive (planning ability and selective attention) and physical function of nursing home residents. Seventeen participants engaged in a 10-week multimodal exercise program and 17 maintained usual activities. Exercise group improved planning ability (25-32%), selective attention (19-67%), and physical function [aerobic endurance, lower body strength, agility, balance, gait, and mobility (19-41%)], corresponding to an effect size ranging from 0.29 (small) to 1.11 (high), p < 0.05. The multimodal exercise program was feasible and well tolerated. The program improved executive and physical functions of the nursing home residents, reverting the usual loss of both cognitive and motor functioning in older adult institutionalized. Multimodal exercise programs may help to maintain or improve nursing home residents' functioning.

We assessed the feasibility and acceptability of using text messages to monitor and encourage physical activity in the first 21 participants enrolled in an ongoing randomized controlled trial evaluating a 16-week Short Message Service/Multimedia Message Service (SMS/MMS) intervention (iSTEP) designed to increase moderate physical activity and improve neurocognition in persons with HIV-associated neurocognitive disorders (HAND; iSTEP, n = 11; control group, n = 10). Data were collected during the intervention and from interviews conducted at the 16-week post-intervention visits. Text message response rates for both iSTEP and control participants were high (89% and 85%, respectively). Pedometer self-monitoring, step count goals, and milestone achievement texts were reported to facilitate physical activity. All iSTEP participants (100%) and 70% of control participants indicated that they would recommend the study to other people living with HIV. The results indicate that it is feasible to administer an SMS/MMS physical activity intervention to persons with HAND. PMID:26847379

2015-01-01

Nowhere is improving understanding and accurate assessment of physical activity more important for disease prevention and health promotion than among health disparities populations such as those residing in rural and Appalachian regions. To enhance accurate assessment of physical activity and potentially improve intervention capacity, we conducted a mixed-methods study examining the acceptability and feasibility of self-report physical activity questionnaires, pedometers, and accelerometers among rural Appalachian children, adolescents, and adults. Most participants reported positive experiences with all three physical activity assessment tools. Several acceptability ratings differed by age group and by sex within each age group. With very few exceptions, no significant differences in acceptability were found by race, education, employment status, health status, BMI categories, income levels, or insurance status within age groups or overall. Several factors may impact the choice of the physical activity assessment method, including target population age, equipment cost, researcher burden, and potential influence on physical activity levels. Children and adolescents appear to have more constraints on when they can wear pedometers and accelerometers. While pedometers are inexpensive and convenient, they may influence physical activity levels, rather than simply measure them. Accelerometers, while less influential on behavior, consume extensive resources, including high purchase costs and researcher burden. PMID:25608476

Effective control of non-communicable diseases and promotion of population-wide physical activity participation require the active engagement of health professionals. Physiotherapists and physicians, as part of their practice, routinely screen and assess physical activity status, and recommend health enhancing physical activity participation for their patients. This study aims to compare Nigerian physiotherapists and physicians' knowledge of physical activity message, role perception and confidence, perceived feasibility and barriers, and overall disposition to promoting physical activity in their practice. A total of 153 physicians and 94 physiotherapists recruited from 10 government hospitals in five states in Northern Nigeria completed a standardized physical activity promotion questionnaire that elicited information on the knowledge of physical activity, role perception and confidence, feasibility, and barriers to physical activity promotion. Descriptive and inferential statistics were used to analyze the data. The physiotherapists and physicians were fairly knowledgeable on physical activity message (14.2 ± 2.1/20), reported minimal or little barrier to physical activity promotion (23.7 ± 3.1/30), perceived physical activity promotion as their role (13.0 ± 1.8/15), were confident in their ability to discuss and recommend physical activity promotion (7.6 ± 1.6/10) and believed promoting physical activity was feasible for them (15.6 ± 2.6/20). However, over 40% of the physiotherapists and physicians do not know the correct dosage of physical activity that could confer health benefits to patients. The physicians showed better overall disposition to physical activity promotion than the physiotherapists ( P  = 0.048), but more physiotherapists than the physicians believed ' it is part of their role to suggest to patients to increase their daily physical activity' (95.7% vs 88.2%, P  = 0.043) and were more 'confident in suggesting specific physical activity programs for their patients' (87.2% vs 64.5%, P  < 0.001). Physiotherapists and physicians in Nigeria demonstrated good disposition to promoting physical activity but many of them have knowledge deficits on the correct dosage required for better health for their patients. These health professionals can serve as good advocates for physical activity promotion in Nigeria, but many of them may require knowledge update on health enhancing physical activity for effective health promotion and primary prevention of non-communicable diseases.

Background In the coming years, the number of survivors of critical illness is expected to increase. These survivors frequently develop newly acquired physical and cognitive impairments. Long-term cognitive impairment is common following critical illness and has dramatic effects on patients' abilities to function autonomously. Neuromuscular weakness affects similar proportions of patients and leads to equally profound life alterations. As knowledge of these short-term and long-term consequences of critical illness has come to light, interventions to prevent and rehabilitate these devastating consequences have been sought. Physical rehabilitation has been shown to improve functional outcomes in people who are critically ill, but subsequent studies of physical rehabilitation after hospital discharge have not. Post-hospital discharge cognitive rehabilitation is feasible in survivors of critical illness and is commonly used in people with other forms of acquired brain injury. The feasibility of early cognitive therapy in people who are critically ill remains unknown. Objective The purpose of this novel protocol trial will be to determine the feasibility of early and sustained cognitive rehabilitation paired with physical rehabilitation in patients who are critically ill from medical and surgical intensive care units. Design This is a randomized controlled trial. Setting The setting for this trial will be medical and surgical intensive care units of a large tertiary care referral center. Patients The participants will be patients who are critically ill with respiratory failure or shock. Intervention Patients will be randomized to groups receiving usual care, physical rehabilitation, or cognitive rehabilitation plus physical rehabilitation. Twice-daily cognitive rehabilitation sessions will be performed with patients who are noncomatose and will consist of orientation, memory, and attention exercises (eg, forward and reverse digit spans, matrix puzzles, letter-number sequences, pattern recognition). Daily physical rehabilitation sessions will advance patients from passive range of motion exercises through ambulation. Patients with cognitive or physical impairment at discharge will undergo a 12-week, in-home cognitive rehabilitation program. Measurements A battery of neurocognitive and functional outcomes will be measured 3 and 12 months after hospital discharge. Conclusions If feasible, these interventions will lay the groundwork for a larger, multicenter trial to determine their efficacy. PMID:22577067

It is important to be able to reliably and feasibly measure infant and toddler physical activity in order to determine adherence to current physical activity guidelines and effects on early life development, growth and health. This study aimed to describe the development of an infant wearable wrist-worn band for the measurement of physical activity; to determine the feasibility of the device data for observational measurement of physical activity and to determine the caregiver reported acceptability of the infant wearable wrist band. After various iterations of prototypes and piloting thereof, a final wearable band was designed to fit an Axivity AX3 monitor. Mother and infant/toddler (aged 3-24 months) pairs ( n  = 152) were recruited, and mothers were asked for their child to wear the band with enclosed monitor at all times for 1 week (minimum 3 days). Feasibility was assessed by determining technical reliability of the data, as well as wear time and compliance according to requirements for observational measurement. Acceptability was assessed via questionnaire. Technical reliability of the Axivity AX3 monitors in this age group was good. After excluding days that did not have at least 15 h of wear time, only 2% of participants had less than three valid days of data remaining, and 4% of participants had no data (due to device loss or data loss). Therefore, 94% of participants were compliant, having three or more days of wear with at least 15 h of wear per day, thus providing enough valid data for observational measurement. The majority (60%) of mothers reported being "very happy" with the safety of the device, while only 8% were "a little worried". A large majority (86%) of mothers stated that the band attracted attention from others, although this was mostly attributed to curiosity about the function of the band. Most (80%) of participants rated the comfort of the band as "comfortable", and 10% rated it as "very comfortable". The infant wearable band proved to be feasible and acceptable according to the criteria tested, and compliance wearing the band was good. We have therefore provided a replicable, comfortable and acceptable wearable band for the measurement of infant and toddler physical activity.

Abstract Objective The aim of our feasibility study was to examine the acceptability and utility of “Dance Dance Revolution” (DDR) (Konami of America, Redwood City, CA)) to increase physical fitness in 8–11-year-old black and Hispanic youth. Subjects and Methods Twenty-eight 4th and 5th grade children attending an afterschool program participated. Outcomes included physical activity, physical fitness, use of home DDR, survey of safety and acceptability, anthropometrics, and fasting metabolic profile measured at baseline, 12 weeks, and 30 weeks. Results At 12 weeks, physical fitness (maximum O2 uptake [VO2max]) increased by 4.9±9.9 percent and was sustained through 30 weeks, when the VO2max was 105.0±9.9 percent (range, 93.0–133.9 percent) of baseline values. Absolute VO2max increased by 2.97±4.99 mL/kg/minute (95% confidence interval 0.75–5.19, P=0.013). Participants maintained an average of 1.12 hours/day of increased movement to music. Trends suggested increased total moderate–vigorous physical activity, decreased light activity, and a modest increase in sedentary screen time. There were no significant changes in body mass index, fasting lipids, or glucose. Participants and parents approved of the activity. Conclusion DDR appears feasible and acceptable to minority youth. DDR may increase moderate–vigorous physical activity and improve physical fitness in at-risk populations. PMID:26196430

The Smithsonian Earth Physics Satellite (SEPS) definition study, volumes 1 through 4

1971-01-01

A limited Phase B study was undertaken to determine the merit and feasibility of launching a proposed earth physics satellite with Apollo-type hardware. The study revealed that it would be feasible to launch this satellite using a S-IB stage, a S-IVB with restart capability, an instrument unit, a SLA for the satellite shroud, and a nose cone (AS-204 configuration). A definition of the proposed satellite is provided, which is specifically designed to satisfy the fundamental requirement of providing an orbiting benchmark of maximum accuracy. The satellite is a completely passive, solid 3628-kg sphere of 38.1-cm radius and very high mass-to-area ratio (7980 kg sq mi). In the suggested orbit of 55 degrees inclination, 3720 km altitude, and low eccentricity, the orbital lifetime is extremely long, so many decades of operation can be expected.

This paper presents the protocol for an ongoing research study to develop and test the feasibility of a multi-behavioral mHealth app. Approximately 27 million women smoke in the US, and more than 180,000 women die of illnesses linked to smoking annually. Women report greater difficulties quitting smoking. Concerns about weight gain, negative body image, and low self-efficacy may be key factors affecting smoking cessation among women. Recent studies suggest that a multi-behavioral approach, including diet and physical activity, may be more effective at helping women quit. Guided imagery has been successfully used to address body image concerns and self-efficacy in our 3 target behaviors-exercise, diet and smoking cessation. However, it has not been used simultaneously for smoking, diet, and exercise behavior in a single intervention. While imagery is an effective therapeutic tool for behavior change, the mode of delivery has generally been in person, which limits reach. mHealth apps delivered via smart phones offer a unique channel through which to distribute imagery-based interventions. The objective of our study is to evaluate the feasibility of an mHealth app for women designed to simultaneously address smoking, diet, and physical activity behaviors. The objectives are supported by three specific aims: (1) develop guided imagery content, user interface, and resources to reduce weight concern, and increase body image and self-efficacy for behavior change among women smokers, (2) program a prototype of the app that contains all the necessary elements of text, graphics, multimedia and interactive features, and (3) evaluate the feasibility, acceptability, and preliminary efficacy of the app with women smokers. We created the program content and designed the prototype application for use on the Android platform in collaboration with 9 participants in multiple focus groups and in-depth interviews. We programmed and tested the application's usability with 6 participants in preparation for an open, pre- and posttest trial. Currently, we are testing the feasibility and acceptability of the application, evaluating the relationship of program use to tobacco cessation, dietary behaviors, and physical activity, and assessing consumer satisfaction with approximately 70 women smokers with Android-based smart phones. The study was started January 1, 2014. The app was launched and feasibility testing began in April 1, 2015. Participants were enrolled from April 1-June 30, 2015. During that time, the app was downloaded over 350 times using no paid advertising. Participants were required to use the app "most days" for 30 days or they would be dropped from the study. We enrolled 151 participants. Of those, 78 were dropped or withdrew from the study, leaving 73 participants. We have completed the 30-day assessment, with a 92% response rate. The 90-day assessment is ongoing. During the final phase of the study, we will be conducting data analyses and disseminating study findings via presentations and publications. Feasibility will be demonstrated by successful participant retention and a high level of app use. We will examine individual metrics (eg, duration of use, number of screens viewed, change in usage patterns over time) and engagement with interactive activities (eg, activity tracking). We will aggregate these data into composite exposure scores that combine number of visits and overall duration to calculate correlations between outcome and measures of program exposure and engagement. Finally, we will compare app use between participants and non-participants using Google Analytics.

This study aimed to assess the feasibility and efficacy of the Great Leaders Active StudentS (GLASS) program, a school-based peer-led physical activity and object control skill intervention. The study employed a quasi-experimental design. The study was conducted in two elementary schools, one intervention and one comparison, in Newcastle, New South Wales (NSW), Australia from April to June 2015 (N=224 students). Peer leaders (n=20) in the intervention school received training to deliver two 30-min object control skill sessions per week to students in Kindergarten, Grades 1 and 2 (5-8 years, n=83) over one school term (10 weeks). The primary outcome was pedometer assessed physical activity during school hours. Secondary outcomes included students' object control skill competency and peers' leadership self-efficacy and teacher ratings of peers' leadership skills. Almost all (19/20) GLASS sessions were delivered by peer leaders who reported high acceptability of the program. The treatment-by-time interaction for students' physical activity during school hours was not significant (p=0.313). The intervention effect on students' overall object control skills was statistically significant (mean difference 5.8 (95% CI 4.1, 7.4; p<0.001)). Teacher-rated peer leadership significantly improved (0.70; 95% CI 0.38-1.01); p<.001)). The GLASS program was found to be both feasible and acceptable. The intervention also resulted in improvements in students' overall object control skills as well as teacher-rated peers' leadership behaviours. Future fully powered trials using peer leaders to deliver fundamental movement skill (FMS) programs are warranted. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

More than 30% of the U.S. population is prehypertensive, and the recommended treatment of lifestyle modification includes increased physical activity. Exercise videogames (EVG) are widely marketed to Americans as a means of increasing fitness. This study aimed to examine EVG among a sample of prehypertensive adults, to determine (1) feasibility and acceptability of EVG for physical activity, and (2) assess changes in (1) estimates of cardiovascular fitness and risk indices, and psychosocial constructs. Participants with prehypertension completed a 12-week program including; 36, 1-hour sessions; supervised EVG program using Nintendo Wii platform and games. Assessments were at baseline and 13 weeks. Paired t-tests were conducted. Fourteen adults (84% female; mean age=53 years; 93% Caucasian; 87% employed) completed the study. The study retention rate was 74% and all participants reported satisfaction and enjoyment in the intervention and using the Wii for exercise. Despite the small sample size, significant improvements were seen in: physical activity minutes (P<0.01), peak heart rate (P=0.02), resting systolic blood pressure (P=0.02), and hip circumference (P=0.03). Significant improvements were also seen in the 36-item short-form survey (SF-36) as for general health (P=0.05), role limitations due to emotional problems (P=0.04), and vitality (P=0.01). Findings support that an EVG program is feasible, acceptable, and promising in promoting benefit to cardiovascular fitness and psychosocial health. These data provide pilot data for the necessary randomized clinical trials to examine efficacy and sustainability of EVG for adult engagement in physical activity for cardiovascular health promotion.

Less than half of American children meet national physical activity (PA) recommendations. This study tested the feasibility, acceptability, and preliminary effectiveness of using wearable PA monitors to increase PA in school-age children. In Phase 1 of this study, conducted in 2014, 32 fifth-grade students enrolled in a low-resource middle school were given a waist-worn Fitbit Zip monitor for 4 weeks to test its feasibility (adherence) and acceptability. Adherence, wear time of ≥8 hours per day, was examined. Feedback was solicited from parents through structured interviews. In Phase 2 , conducted in 2015, 42 sixth-grade students were assigned, by classroom, to one of three conditions (Fitbit + goal and incentive-based intervention, Fitbit only, or control) to test the feasibility of the wrist-worn Fitbit Charge and its preliminary effectiveness in increasing PA over 6 weeks. In Phase 1 , average adherence was 64.1%. In Phase 2 , it was 73.4% and 80.2% for participants in the Fitbit + intervention and Fitbit only groups, respectively ( p = .07). After controlling for baseline values, weight status, and sex, there were no significant group differences in changes in MVPA or steps from baseline to follow-up. While moderately acceptable, wearable PA monitors did not increase PA levels in this sample. They may be more effective within a coordinated school-based physical activity program.

A growing body of observational evidence suggests that nutritional and physical activity interventions are associated with beneficial outcomes for men with prostate cancer, including brisk walking, lycopene intake, increased fruit and vegetable intake and reduced dairy consumption. However, randomised controlled trial data are limited. The 'Prostate Cancer: Evidence of Exercise and Nutrition Trial' investigates the feasibility of recruiting and randomising men diagnosed with localised prostate cancer and eligible for radical prostatectomy to interventions that modify nutrition and physical activity. The primary outcomes are randomisation rates and adherence to the interventions at 6 months following randomisation. The secondary outcomes are intervention tolerability, trial retention, change in prostate specific antigen level, change in diet, change in general physical activity levels, insulin-like growth factor levels, and a range of related outcomes, including quality of life measures. The trial is factorial, randomising men to both a physical activity (brisk walking or control) and nutritional (lycopene supplementation or increased fruit and vegetables with reduced dairy consumption or control) intervention. The trial has two phases: men are enrolled into a cohort study prior to radical prostatectomy, and then consented after radical prostatectomy into a randomised controlled trial. Data are collected at four time points (cohort baseline, true trial baseline and 3 and 6 months post-randomisation). The Prostate Cancer: Evidence of Exercise and Nutrition Trial aims to determine whether men with localised prostate cancer who are scheduled for radical prostatectomy can be recruited into a cohort and subsequently randomised to a 6-month nutrition and physical activity intervention trial. If successful, this feasibility trial will inform a larger trial to investigate whether this population will gain clinical benefit from long-term nutritional and physical activity interventions post-surgery. Prostate Cancer: Evidence of Exercise and Nutrition Trial (PrEvENT) is registered on the ISRCTN registry, ref number ISRCTN99048944. Date of registration 17 November 2014.

Physical activity is markedly low in Latina adolescents, yet few physical activity interventions have been attempted in this population. Web-based interventions can incorporate theory-based components, be appealing to adolescents, and have potential for low-cost dissemination. This study aimed to assess the feasibility, acceptability, and potential efficacy of a Web-based physical activity intervention for Latina adolescents in a single-arm pilot trial. A total of 21 Latina adolescents (aged 12-18 years) who could read and write in English and were underactive (<90 min/week) participated in a 12-week, theory-informed Web-based physical activity intervention. The intervention website was modified from a previous Web-based intervention for Latina adults. Web content was individually tailored based on the responses to monthly questionnaires. Feasibility was measured by recruitment, retention, and adherence/engagement, and acceptability was measured by satisfaction surveys. Physical activity was measured at baseline and follow-up (12 weeks) using the 7-day physical activity recall (PAR) interview and accelerometers. Baseline activity as measured by the 7-day PAR and accelerometers was 24.7 (SD 26.11) and 24.8 (SD 38.3) min/week, respectively. At 12 weeks, 19 participants (90%, 19/21) returned. Adherence and engagement with materials were low, but 72% (15/21) of the participants indicated that they were satisfied with the intervention. Activity at 12 weeks increased by 58.8 (SD 11.33) min/week measured by the 7-day PAR (P<.001). Accelerometer-measured activity did not increase. Activities reported at follow-up were more varied than at baseline, including some activities measured poorly by accelerometers (eg, biking and swimming). Participants suggested simplifying the website and incorporating other technologies. Good retention and increases in self-reported activity suggest a promising approach to delivering a physical activity intervention to Latina adolescents. Incorporating other technologies, such as smartphone apps, could make the intervention more engaging, acceptable, and effective. ©Britta Larsen, Tanya Benitez, Mayra Cano, Shira S Dunsiger, Bess H Marcus, Andrea Mendoza-Vasconez, James F Sallis, Michelle Zive.

Studies have established the importance of physical activity and fitness, yet limited data exist on the associations between objective, real-world physical activity patterns, fitness, sleep, and cardiovascular health. To assess the feasibility of obtaining measures of physical activity, fitness, and sleep from smartphones and to gain insights into activity patterns associated with life satisfaction and self-reported disease. The MyHeart Counts smartphone app was made available in March 2015, and prospective participants downloaded the free app between March and October 2015. In this smartphone-based study of cardiovascular health, participants recorded physical activity, filled out health questionnaires, and completed a 6-minute walk test. The app was available to download within the United States. The feasibility of consent and data collection entirely on a smartphone, the use of machine learning to cluster participants, and the associations between activity patterns, life satisfaction, and self-reported disease. From the launch to the time of the data freeze for this study (March to October 2015), the number of individuals (self-selected) who consented to participate was 48 968, representing all 50 states and the District of Columbia. Their median age was 36 years (interquartile range, 27-50 years), and 82.2% (30 338 male, 6556 female, 10 other, and 3115 unknown) were male. In total, 40 017 (81.7% of those who consented) uploaded data. Among those who consented, 20 345 individuals (41.5%) completed 4 of the 7 days of motion data collection, and 4552 individuals (9.3%) completed all 7 days. Among those who consented, 40 017 (81.7%) filled out some portion of the questionnaires, and 4990 (10.2%) completed the 6-minute walk test, made available only at the end of 7 days. The Heart Age Questionnaire, also available after 7 days, required entering lipid values and age 40 to 79 years (among 17 245 individuals, 43.1% of participants). Consequently, 1334 (2.7%) of those who consented completed all fields needed to compute heart age and a 10-year risk score. Physical activity was detected for a mean (SD) of 14.5% (8.0%) of individuals' total recorded time. Physical activity patterns were identified by cluster analysis. A pattern of lower overall activity but more frequent transitions between active and inactive states was associated with equivalent self-reported cardiovascular disease as a pattern of higher overall activity with fewer transitions. Individuals' perception of their activity and risk bore little relation to sensor-estimated activity or calculated cardiovascular risk. A smartphone-based study of cardiovascular health is feasible, and improvements in participant diversity and engagement will maximize yield from consented participants. Large-scale, real-world assessment of physical activity, fitness, and sleep using mobile devices may be a useful addition to future population health studies.

Review of researches on smartphone applications for physical activity promotion in healthy adults

Physical activity is known as a preventative method for preventing life-style-related diseases. Smartphone applications for health and fitness intervention have released with rapid increase of innovative technology. Reviews of recent publications on mobile application have been conducted to observe feasibility and applicability for physical activity intervention. Bibliographic searches of PubMed and ScienceDirect were conducted with key terms, ‘physical activity,’ ‘fitness,’ ‘smart-phone,’ and ‘health’ between the years 2014 and 2017 to obtain 5,087 publications. Out of 5,087 articles, five articles on sensor-based applications and five articles on user entry-based applications were obtained through the inclusion and exclusion processes. Accuracy of the physical activity assessments were reported to be high in comparison to the conventional assessment tools. The overall subject rating on the app motivational ratings were positive with high correlation between physical activity and treats and cues. The adherence rates to the apps significantly dropped prior to 3 months. Publications that elucidate feasibility and accuracy of smartphone applications that motivates physical activity seem limited with adequately conducted study designs. Large-scaled, control-compared, long-term randomized control trials should be conducted to elucidate the effects of the app interventions. PMID:28349027

Active video games (AVGs) capable of inducing physical activity offer an innovative approach to combating childhood obesity. Unfortunately, children's AVG game play decreases quickly, underscoring the need to identify novel methods for player engagement. Narratives have been demonstrated to influence behaviors. The objective of this study was to test the hypothesis that a narrative would motivate increased AVG play, though a feasibility study that investigated the motivational effect of adding a previously developed narrative cutscene to an originally nonnarrative AVG, Nintendo Wii Sports Resort: Swordplay Showdown. A total of 40 overweight and obese 8- to 11-year-olds equally divided by sex played the AVG. Half (n=20) were randomly assigned to a narrative group that watched the narrative cutscene before game play. The other half played the game without watching it. Children in the narrative group had significantly (P<.05) more steps per 10-second period (mean 3.2, SD 0.7) and overall (mean 523, SD 203) during game play compared with the nonnarrative group (10-second period: mean 2.7, SD 0.7; overall: mean 366, SD 172). The AVG with narrative induced increased physical activity. Additional research is needed to understand the mechanisms through which narrative increases physical activity during AVG game play.

Background Active video games (AVGs) capable of inducing physical activity offer an innovative approach to combating childhood obesity. Unfortunately, children’s AVG game play decreases quickly, underscoring the need to identify novel methods for player engagement. Narratives have been demonstrated to influence behaviors. Objective The objective of this study was to test the hypothesis that a narrative would motivate increased AVG play, though a feasibility study that investigated the motivational effect of adding a previously developed narrative cutscene to an originally nonnarrative AVG, Nintendo Wii Sports Resort: Swordplay Showdown. Methods A total of 40 overweight and obese 8- to 11-year-olds equally divided by sex played the AVG. Half (n=20) were randomly assigned to a narrative group that watched the narrative cutscene before game play. The other half played the game without watching it. Results Children in the narrative group had significantly (P<.05) more steps per 10-second period (mean 3.2, SD 0.7) and overall (mean 523, SD 203) during game play compared with the nonnarrative group (10-second period: mean 2.7, SD 0.7; overall: mean 366, SD 172). Conclusions The AVG with narrative induced increased physical activity. Additional research is needed to understand the mechanisms through which narrative increases physical activity during AVG game play. PMID:27742605

Physical activity is effective in improving glycemic control in diabetes mellitus. Yet only 40% of people meet the recommended level of physical activity. Nintendo Wii tennis has an energy expenditure of moderate intensity, and may be a viable part of a physical activity programme. Eleven older people with diabetes who were sedentary participated in a pre-post-test designed study to examine physical activity levels, muscle strength, and physical performance after 4 weeks of group Nintendo Wii training. Significant effects occurred on moderate physical activity time, total physical activity, dominant handgrip strength, non-dominant handgrip strength, 30 second chair stand and 400m walk test. No effect was observed for BMI, quality of life, or balance. This study provided preliminary evidence of the effectiveness of group-based active video game programme on physical activity levels.

The aim of this study was to determine the feasibility of a combined supervised and home-based exercise intervention during chemotherapy for women with recurrent ovarian cancer. Secondary aims were to determine the impact of physical activity on physical and psychological outcomes and on chemotherapy completion rates. Women with recurrent ovarian cancer were recruited from 3 oncology outpatient clinics in Sydney and Canberra, Australia. All participants received an individualized exercise program that consisted of 90 minutes or more of low to moderate aerobic, resistance, core stability, and balance exercise per week, for 12 weeks. Feasibility was determined by recruitment rate, retention rate, intervention adherence, and adverse events. Aerobic capacity, muscular strength, fatigue, sleep quality, quality of life, depression, and chemotherapy completion rates were assessed at weeks 0, 12, and 24. Thirty participants were recruited (recruitment rate, 63%), with a retention rate of 70%. Participants averaged 196 ± 138 min · wk of low to moderate physical activity throughout the intervention, with adherence to the program at 81%. There were no adverse events resulting from the exercise intervention. Participants who completed the study displayed significant improvements in quality of life (P = 0.017), fatigue (P = 0.004), mental health (P = 0.007), muscular strength (P = 0.001), and balance (P = 0.003) after the intervention. Participants completing the intervention had a higher relative dose intensity than noncompleters (P = 0.03). A program consisting of low to moderate exercise of 90 min · wk was achieved by two-thirds of women with recurrent ovarian cancer in this study, with no adverse events reported. Randomized control studies are required to confirm the benefits of exercise reported in this study.

Safe patient handling perceptions and practices: a survey of acute care physical therapists.

Olkowski, Brian F; Stolfi, Angela M

Acute care physical therapists are at risk for developing work-related musculoskeletal disorders (WMSDs) due to manual patient handling. Safe patient handling (SPH) reduces WMSDs caused by manual handling. The purpose of this study was to describe the patient handling practices of acute care physical therapists and their perceptions regarding SPH. Additionally, this study determined whether an SPH program influences the patient handling practices and perceptions regarding SPH of acute care physical therapists. Subscribers to the electronic discussion board of American Physical Therapy Association's Acute Care Section were invited to complete a survey questionnaire. The majority of respondents used SPH equipment and practices (91.1%), were confident using SPH equipment and practices (93.8%), agreed that evidence supports the use of SPH equipment and practices (87.0%), and reported the use of SPH equipment and practices is feasible (92.2%). Respondents at a facility with an SPH program were more likely to use SPH equipment and practices, have received training in the use of SPH equipment and practices, agree that the use of SPH equipment and practices is feasible, and feel confident using SPH equipment and practices. The study might not reflect the perceptions and practices of the population of acute care physical therapists. Acute care physical therapists are trained to use SPH equipment and practices, use SPH equipment and practices, and have positive perceptions regarding SPH. Acute care physical therapists in a facility with an SPH program are more likely to use SPH equipment and practices, receive training in SPH equipment and practices, and have positive perceptions regarding SPH. Quasi-regulatory organizations should incorporate SPH programs into their evaluative standards.

The World Wide Web is an effective method for delivering health behavior programs, yet major limitations remain (eg, cost of development, time and resource requirements, limited interactivity). Social media, however, has the potential to deliver highly customizable and socially interactive behavioral interventions with fewer constraints. Thus, the evaluation of social media as a means to influence health behaviors is warranted. The objective of this trial was to examine and demonstrate the feasibility of using an established social networking platform (ie, Facebook) to deliver an 8 week physical activity intervention to a sample of low-active adolescents (N=21; estimated marginal mean age 13.48 years). Participants were randomized to either an experimental (ie, Behavioral) or attentional control (ie, Informational) condition. Both conditions received access to a restricted-access, study-specific Facebook group where the group's administrator made two daily wall posts containing youth-based physical activity information and resources. Primary outcomes included physical activity as assessed by accelerometry and self-report. Interactions and main effects were examined, as well as mean differences in effect sizes. Analyses revealed significant improvements over time on subjectively reported weekly leisure-time physical activity (F1,18=8.426, P=.009, η2 = .319). However, there was no interaction between time and condition (F1,18=0.002, P=.968, η2 = .000). There were no significant time or interaction effects among the objectively measured physical activity variables. Examination of effect sizes revealed moderate-to-large changes in physical activity outcomes. Results provide initial support for the feasibility of delivery of a physical activity intervention to low-active adolescents via social media. Whether by employing behavioral interventions via social media can result in statistically meaningful changes in health-related behaviors and outcomes remains to be determined.

Physical activity, healthy eating and maintaining a healthy weight are associated with reduced risk of cardiovascular disease, type 2 diabetes and cancer and with improved mental health. Despite these benefits, many men do not meet recommended physical activity guidelines and have poor eating behaviours. Many health promotion programmes hold little appeal to men and consequently fail to influence men's health practices. HAT TRICK was designed as a 12-week face-to-face, gender-sensitised intervention for overweight and inactive men focusing on physical activity, healthy eating and social connectedness and was delivered in collaboration with a major junior Canadian ice hockey team (age range 16-20 years). The programme was implemented and evaluated to assess its feasibility. This article describes the intervention design and study protocol of HAT TRICK. HAT TRICK participants (n=60) were men age 35 years, residing in the Okanagan Region of British Columbia, who accumulate 150 min of moderate to vigorous physical activity a week, with a body mass index of >25 kg/m 2 and a pant waist size of >38'. Each 90 min weekly session included targeted health education and theory-guided behavioural change techniques, as well as a progressive (ie, an increase in duration and intensity) group physical activity component. Outcome measures were collected at baseline, 12 weeks and 9 months and included the following: objectively measured anthropometrics, blood pressure, heart rate, physical activity and sedentary behaviour, as well as self-reported physical activity, sedentary behaviour, diet, smoking, alcohol consumption, sleep habits, risk of depression, health-related quality of life and social connectedness. Programme feasibility data (eg, recruitment, satisfaction, adherence, content delivery) were assessed at 12 weeks via interviews and self-report. Ethical approval was obtained from the University of British Columbia Okanagan Behavioural Research Ethics Board (reference no H1600736). Study findings will be disseminated through academic meetings, peer-reviewed publication, web-based podcasts, social media, plain language summaries and co-delivered community presentations.

Exercise interventions are efficacious in reducing cardiometabolic risk and improving symptoms in people with severe mental illness, yet evidence guiding the implementation and scalability of such efforts is lacking. Given increasing efforts to address the disparity in physical health outcomes facing people with a mental illness, novel approaches to increasing adoption of effective interventions are required. Exercise interventions targeting mental health staff may improve staff health while also creating more positive attitudes towards the role of lifestyle interventions for people experiencing mental illness. We aimed to determine the feasibility, acceptability and effectiveness of exercise interventions delivered to staff working in mental health services. A systematic review was conducted from database inception, until November 2017. Studies recruiting staff participants to receive an exercise intervention were eligible for inclusion. Five studies met the inclusion criteria. Physical health interventions for mental health staff were feasible and acceptable with low dropout rates. Reductions in anthropometric measures and work-related stress were reported. Limited evidence suggests that exercise interventions targeting mental health staff are feasible and acceptable. Further research is required to determine the efficacy of such interventions and the impact such strategies may have on staff culture and patient outcomes.

We investigated whether active video gaming (AVG) could bring about regular, enjoyable, physical exercise in children treated for brain tumours, what level of physical activity could be reached and if the children's physical functioning improved. Thirteen children, aged 7-17 years, were randomised to either AVG or waiting-list. After 10-12 weeks they crossed-over. Weekly Internet coaching sessions were used to sustain motivation and evaluate enjoyment. Energy expenditure (EE) levels were measured as Metabolic Equivalent of Task (MET), using a multisensory activity monitor. Single-blinded assessments of physical functioning were done, using the Bruininks-Osteretsky Test of Motor Performance, second edition, evaluating participants before and after the intervention period, as well as comparing the randomisation groups after the first period. All patients completed the study. AVG sessions (mean duration 47 minutes) were performed on 72% of all days. Mean EE level during AVG sessions was 3.0 MET, corresponding to moderate physical activity. The Body Coordination score improved by 15% (p = 0.021) over the intervention period. In this group of childhood brain tumour survivors, home-based AVG, supported by a coach, was a feasible, enjoyable and moderately intense form of exercise that improved Body Coordination. Implications for Rehabilitation Childhood brain tumour survivors frequently have cognitive problems, inferior physical functioning and are less physically active compared to their healthy peers. Active video gaming (AVG), supported by Internet coaching, is a feasible home-based intervention in children treated for brain tumours, promoting enjoyable, regular physical exercise of moderate intensity. In this pilot study, AVG with Nintendo Wii improved Body Coordination.

Holistic exercise for people with dementia could have psychological and physical benefits, but there is a lack of research on the experience of this type of exercise. Therefore, the objective of this study was to determine the feasibility and acceptance of holistic exercise among people with dementia. A holistic exercise programme for people with dementia was designed and implemented. Semi-structured interviews were undertaken to explore participants' experience of holistic exercise, transcribed verbatim and analyzed. Seven themes were generated from the data. They were enjoyment, relaxation, keeping active, social interaction, pain relief, learning something new and intention to continue, respectively. The results of the current small-scale study provide evidence for the feasibility and acceptance of holistic exercise for people with dementia. In addition, participants appeared to benefit in terms of psychological and physical wellbeing. Copyright © 2014 Elsevier Ltd. All rights reserved.

Microwave Sanitization of Color Additives Used in Cosmetics: Feasibility Study

Microwave exposure has been explored as a method of microbiologically sanitizing color additives used in cosmetic products. Selected microbiologically unacceptable cosmetic color additives, D&C red no. 7 Ca lake (certified synthetic organic color), carmine (natural organic color not subject to certification), and chromium hydroxide green (inorganic color not subject to certification), were submitted to microwave exposure. Gram-negative bacteria were eliminated, as verified by enrichment procedures, and levels of gram-positive bacteria were reduced. Generally, analytical and dermal safety studies indicated no significant alterations in physical, chemical, and toxicological properties of the colors. Sanitization was also successfully performed on other colors (D&C red no. 9 Ba lake, D&C red no. 12 Ba lake, D&C green no. 5, and FD&C red no. 4); initial physical and chemical tests were satisfactory. Results indicated that this method of sanitization is feasible and warrants further investigation. PMID:1164010

Mental health inpatients' and staff members' suggestions for reducing physical restraint: A qualitative study.

PubMed

Wilson, C; Rouse, L; Rae, S; Kar Ray, M

2018-04-01

WHAT IS KNOWN ON THE SUBJECT?: Restraint has negative psychological, physical and relational consequences for mental health patients and staff. Restraint reduction interventions have been developed (e.g., "Safewards"). Limited qualitative research has explored suggestions on how to reduce physical restraint (and feasibility issues with implementing interventions) from those directly involved. WHAT DOES THIS PAPER ADD TO EXISTING KNOWLEDGE?: This paper explores mental health patients' and staff members' suggestions for reducing physical restraint, whilst addressing barriers to implementing these. Findings centred on four themes: improving communication and relationships; staffing factors; environment and space; and activities and distraction. Not all suggestions are addressed by currently available interventions. Barriers to implementation were identified, centring on a lack of time and/or resources; with the provision of more time for staff to spend with patients and implement interventions seen as essential to reducing physical restraint. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Improving communication and relationships between staff/patients, making staffing-related changes, improving ward environments and providing patient activities are central to restraint reduction in mental healthcare. Fundamental issues related to understaffing, high staff turnover, and lack of time and resources need addressing in order for suggestions to be successfully implemented. Introduction Physical restraint has negative consequences for all involved, and international calls for its reduction have emerged. Some restraint reduction interventions have been developed, but limited qualitative research explores suggestions on how to reduce physical restraint (and feasibility issues with implementation) from those directly involved. Aims To explore mental health patients' and staff members' suggestions for reducing physical restraint. Methods Interviews were conducted with 13 inpatients and 22 staff members with experience of restraint on adult mental health inpatient wards in one UK National Health Service Trust. Results Findings centred on four overarching themes: improving communication and relationships between staff/patients; making staff-related changes; improving ward environments/spaces; and having more activities. However, concerns were raised around practicalities/feasibility of their implementation. Discussion Continued research is needed into best ways to reduce physical restraint, with an emphasis on feasibility/practicality and how to make time in busy ward environments. Implications for Practice Improving communication and relationships between staff/patients, making staffing-related changes, improving ward environments and providing patient activities are central to restraint reduction in mental healthcare. However, fundamental issues related to understaffing, high staff turnover and lack of time/resources need addressing in order for these suggestions to be successfully implemented. © 2018 John Wiley & Sons Ltd.

Participation in physical activity has a positive impact on the overall health and quality of life, whereas physical inactivity is associated with a poor prognosis among breast cancer survivors. Despite the health-enhancing benefits of physical activity, the majority of Malaysian breast cancer survivors are not physically active. This paper presents the design of a randomised study to evaluate the feasibility and effect of exercise therapy intervention using light resistance dumbbell exercise to promote active lifestyle and improve the quality of life of breast cancer survivors in Malaysia. This is an intervention study of a 12-week exercise therapy that will explore and compare the effects of light resistance and aerobic exercise on physical activity level and quality of life components in 102 female breast cancer survivors. Major eligibility criteria include histologically confirmed diagnosis of breast cancer stages I-III, 3-12 months post-diagnosis, and absence of any disorder contraindicating exercise. Participants will be stratified based on menopausal status (pre-menopause vs post-menopause) and then assigned randomly to one of three groups. Participants in group A will participate in a three-times weekly supervised resistance exercise using light resistance dumbbells; participants in group B will participate in a three-times weekly supervised aerobic exercise; while participants in group C (control group) will be given aerobic exercise after completion of the intervention. The primary end points include physical activity level and quality of life components. The secondary end points are body mass index, body composition, total caloric intake, and waist-to-hip ratio. Although there have been many studies of resistance exercise in breast cancer survivors, this is the first study using this specific mode of resistance. Findings will contribute data on the feasibility and effects of light resistance dumbbell exercises, and provide knowledge on the physical activity intervention programme that will maximally promote better overall health and well-being of survivors.

Social facilitation maintenance treatment for adults with obesity: study protocol for a randomised-controlled feasibility study (SFM study).

Hilbert, Anja

2016-08-31

The long-term success of non-surgical weight loss treatment in adults with obesity is limited by substantial relapse, and only a few evidence-based weight loss maintenance treatments exist. This clinical trial investigates the feasibility and efficacy of a social facilitation maintenance programme for weight loss maintenance, tailored to meet the needs of obese adults who have undergone a lifestyle weight loss intervention. In a single-centre, open feasibility trial, 72 adults currently or previously obese or overweight who have undergone a lifestyle weight loss intervention are centrally randomised to 4 months of social facilitation maintenance treatment or treatment as a usual control condition. In 16 outpatient group sessions, the social facilitation maintenance treatment, based on a socioecological model and on evidence supporting social facilitation as a key process in maintaining weight loss, focuses on promoting interpersonal relationships to build up a healthy lifestyle for long-term weight loss maintenance. Primary outcome is the amount of weight regain at 6-month follow-up, compared with pre-treatment weight, derived from measured body weight. Secondary outcomes address feasibility, including recruitment, attrition, assessment non-completion, compliance and patients' programme evaluation; and in comparison with pre-weight loss maintenance, social and interpersonal functioning, eating behaviour and physical activity, psychological and physical symptoms, body composition and risk of comorbidity, and quality of life at post-treatment and follow-up assessments. The study was approved by the Ethical Committee at the University of Leipzig (165-13-15072013). The study results will be disseminated through peer-reviewed publications. DRKS00005182.

This paper describes an investigation of the practicability of utilizing hollow fiber membranes in vehicular and portable life support system applications. A preliminary screening of potential advanced life support applications resulted in the selection of five applications for feasibility study and testing. As a result of the feasibility study and testing, three applications, heat rejection, deaeration, and bacteria filtration, were chosen for breadboard development testing. Breadboard hardware has been manufactured and tested, and the physical properties of the three hollow fiber membrane assemblies applicable to use aboard future spacecraft have been characterized.

Evaluation of different recruitment and randomisation methods in a trial of general practitioner-led interventions to increase physical activity: a randomised controlled feasibility study with factorial design

PubMed Central

2014-01-01

Background Interventions promoting physical activity by General Practitioners (GPs) lack a strong evidence base. Recruiting participants to trials in primary care is challenging. We investigated the feasibility of (i) delivering three interventions to promote physical activity in inactive participants and (ii) different methods of participant recruitment and randomised allocation. Methods We recruited general practices from Devon, Bristol and Coventry. We used a 2-by-2 factorial design for participant recruitment and randomisation. Recruitment strategies were either opportunistic (approaching patients attending their GP surgery) or systematic (selecting patients from practice lists and approaching them by letter). Randomisation strategies were either individual or by practice cluster. Feasibility outcomes included time taken to recruit the target number of participants within each practice. Participants were randomly allocated to one of three interventions: (i) written advice (control); (ii) brief GP advice (written advice plus GP advice on physical activity), and (iii) brief GP advice plus a pedometer to self-monitor physical activity during the trial. Participants allocated to written advice or brief advice each received a sealed pedometer to record their physical activity, and were instructed not to unseal the pedometer before the scheduled day of data collection. Participant level outcomes were reported descriptively and included the mean number of pedometer steps over a 7-day period, and European Quality of Life (EuroQoL)-5 dimensions (EQ-5D) scores, recorded at 12 weeks’ follow-up. Results We recruited 24 practices (12 using each recruitment method; 18 randomising by cluster, 6 randomising by individual participant), encompassing 131 participants. Opportunistic recruitment was associated with less time to target recruitment compared with systematic (mean difference (days) -54.9, 95% confidence interval (CI) -103.6; -6.2) but with greater loss to follow up (28.8% versus. 6.9%; mean difference 21.9% (95% CI 9.6%; 34.1%)). There were differences in the socio-demographic characteristics of participants according to recruitment method. There was no clear pattern of change in participant level outcomes from baseline to 12 weeks across the three arms. Conclusions Delivering and trialling GP-led interventions to promote physical activity is feasible, but trial design influences time to participant recruitment, participant withdrawal, and possibly, the socio-demographic characteristics of participants.

Physical exercises and physiotherapy are of great importance for maintenance of joint function in patients with rheumatoid arthritis (RA). However, many RA patients complain about problems to receive prescriptions or have a lack of access to physiotherapy. Recent reports have shown positive effects of the Wii game console on physical and psychosocial conditions of patients with other underlying diseases. The primary objectives of this prospective controlled pilot study were to investigate feasibility and patients' assessment using an animated home-based exercise program. This pilot study was conducted as a single-center, cross-over trial with two treatment arms over 24 weeks. Eligibility criteria included patients with RA reaching low disease activity under therapy with a biological disease modifying anti-rheumatic drug (bDMARD). After detailed instruction, 15 patients started with a conventional home-based physical exercise program and 15 patients began with a predefined animated exercise program by using the Wii game console for 12 weeks. Afterwards, patients were crossed-over to the other treatment arm for another period of 12 weeks. Multi-methodical assessments were performed by qualitative analysis of the interview-data as well as statistical analysis of functional tests and patient reported outcomes (PRO's). Evaluation of the interviews indicated feasibility and usefulness of the chosen animated home-based exercise program. Forefoot disabilities were identified as a main limiting factor for performing some of the animated exercises. After 12 weeks, both treatment arms showed improvement of functional tests without significant differences between groups: Overall muscle strength improved for a mean value of 10 Newton (+12 %) and the mean 6-min walk test (6-MWT) distance increased for 28 meters (+5 %). This study showed that an animated home-based exercise program by using a Wii game console was feasible and beneficial for RA patients. Compared to standard physical home exercises, similar effects were observed indicating that such an animated program might be an alternative supportive option for RA patients.

Pilot and feasibility work is conducted to evaluate the operational feasibility and acceptability of the intervention itself and the feasibility and acceptability of a trials' protocol design. The Cardiac Rehabilitation In Bowel cancer (CRIB) study was a pilot randomised controlled trial (RCT) of cardiac rehabilitation versus usual care (no rehabilitation) for post-surgical colorectal cancer patients. A key aim of the pilot trial was to test the feasibility and acceptability of the protocol design. A pilot RCT with embedded qualitative work was conducted in three sites. Participants were randomly allocated to cardiac rehabilitation or usual care groups. Outcomes used to assess the feasibility and acceptability of key trial parameters were screening, eligibility, consent, randomisation, adverse events, retention, completion, missing data, and intervention adherence rates. Colorectal patients' and clinicians' perceptions and experiences of the main trial procedures were explored by interview. Quantitative study. Three sites were involved. Screening, eligibility, consent, and retention rates were 79 % (156/198), 67 % (133/198), 31 % (41/133), and 93 % (38/41), respectively. Questionnaire completion rates were 97.5 % (40/41), 75 % (31/41), and 61 % (25/41) at baseline, follow-up 1, and follow-up 2, respectively. Sixty-nine percent (40) of accelerometer datasets were collected from participants; 31 % (20) were removed for not meeting wear-time validation. Qualitative study: Thirty-eight patients and eight clinicians participated. Key themes were benefits for people with colorectal cancer attending cardiac rehabilitation, barriers for people with colorectal cancer attending cardiac rehabilitation, generic versus disease-specific rehabilitation, key concerns about including people with cancer in cardiac rehabilitation, and barriers to involvement in a study about cardiac rehabilitation. The study highlights where threats to internal and external validity are likely to arise in any future studies of similar structured physical activity interventions for colorectal cancer patients using similar methods being conducted in similar contexts. This study shows that there is likely to be potential recruitment bias and potential imprecision due to sub-optimal completion of outcome measures, missing data, and sub-optimal intervention adherence. Hence, strategies to manage these risks should be developed to stack the odds in favour of conducting successful future trials. ISRCTN63510637.

During the preparatory phase of the baseline survey of the IDEFICS (Identification and prevention of dietary- and lifestyle-induced health effects in children and infants) study, standardised survey procedures including instruments, examinations, methods, biological sampling and software tools were developed and pretested for their feasibility, robustness and acceptability. A pretest was conducted of full survey procedures in 119 children aged 2-9 years in nine European survey centres (N(per centre)=4-27, mean 13.22). Novel techniques such as ultrasound measurements to assess subcutaneous fat and bone health, heart rate monitors combined with accelerometers and sensory taste perception tests were used. Biological sampling, physical examinations, sensory taste perception tests, parental questionnaire and medical interview required only minor amendments, whereas physical fitness tests required major adaptations. Callipers for skinfold measurements were favoured over ultrasonography, as the latter showed only a low-to-modest agreement with calliper measurements (correlation coefficients of r=-0.22 and r=0.67 for all children). The combination of accelerometers with heart rate monitors was feasible in school children only. Implementation of the computer-based 24-h dietary recall required a complex and intensive developmental stage. It was combined with the assessment of school meals, which was changed after the pretest from portion weighing to the more feasible observation of the consumed portion size per child. The inclusion of heel ultrasonometry as an indicator of bone stiffness was the most important amendment after the pretest. Feasibility and acceptability of all procedures had to be balanced against their scientific value. Extensive pretesting, training and subsequent refinement of the methods were necessary to assess the feasibility of all instruments and procedures in routine fieldwork and to exchange or modify procedures that would otherwise give invalid or misleading results.

Physical activity can decrease the risk of complications related to diabetes type 2. Feasible and scalable strategies to implement support for a healthy lifestyle for patients in primary care are needed. The aim of the DiaCert-study is to evaluate a digital healthcare platform and the effect of a 12-week long smartphone-app physical activity intervention aiming at increasing physical activity (primary outcome) and improve levels of HbA1c (glycated hemoglobin), blood lipids, blood pressure, body composition, as well as other lifestyle factors and overall health in patients with diabetes type 2. The DiaCert-study is a two-arm, randomized controlled trial that will include 250 patients with diabetes type 2. At baseline, participants are randomized 1:1 to intervention, i.e. use of the smartphone-app, during 12 weeks, or to a control group receiving only standard care. Physical activity and sedentary behavior, is objectively measured using the Actigraph GT3X. Biomarkers including HbA1c and blood lipids are measured in fasting blood samples. Anthropometrics include height, weight, waist circumference and body composition, and a number of lifestyle factors including sleep, diet, self-efficacy, and quality of life, are assessed through an extensive questionnaire. Measurements are made at baseline and at follow-up after 3, 6 and 12 months. Using new technology, is one way to bridge the gap between what patients need and what health care can offer. This study evaluates a new digital health care platform and will show if use of a smartphone-app to promote daily steps is an effective and feasible method to increase physical activity and improve clinical markers in patients with diabetes type 2.

To review mobile games and gaming applications that claim to improve physical activity behavior in daily life. We searched PubMed, Web of Science, and the ACM Digital Library and performed a manual search of relevant journals and reference lists. Studies that reported on a mobile game that requires players to perform physical activity in daily life and where the game has specific goals, rules, and feedback mechanisms were included. This excludes non-mobile exergames. Theoretical foundations, game characteristics, and evaluation methodologies were assessed. In total, 797 articles were identified through the search, of which 11 articles were included. The reviewed studies show that there is limited theoretical foundation for the game development, and most studies used goal setting as a motivation strategy to engage people in playing the game. There was a large variety in game characteristics found, although the majority of the studies used metaphors or avatars to visualize activity, whereas feedback was mostly provided in relation to the goal. Rewards and competition were the most commonly incorporated game elements. The evaluations were focused on feasibility, and clinical evidence is lacking with only two randomized controlled studies found. This review provides a first overview of mobile gaming applications to promote daily life physical activity and shows this as a new research area with demonstration of its acceptability and feasibility among the users. Clinical effectiveness and the added value of gaming in changing daily activity behavior have by far not yet been established.

The present study explores the feasibility of telestenting, wherein a physician operator performs stenting on a patient in a separate physical location using a combination of robotics and telecommunications. Patients undergoing robotic stenting were eligible for inclusion. All manipulations of guidewires, balloons, and stents were performed robotically by a physician operator located in an isolated separate room outside the procedure room housing the patient. Communication between the operating physician and laboratory personnel was via telecommunication devices providing real-time audio and video connectivity. Among 20 patients who consented to participate, technical success, defined as successful advancement and retraction of guidewires, balloons, and stents by the robotic system without conversion to manual operation, was achieved in 19 of 22 lesions (86.4%). Procedural success, defined as <30% residual stenosis upon completion of the procedure in the absence of death or repeat revascularisation prior to hospital discharge, was achieved in 19 of 20 patients (95.0%). There were no deaths or repeat revascularisations prior to hospital discharge. To the best of our knowledge, the present study is the first to explore the feasibility of telestenting. Additional studies are required to determine if future advancements in robotics will facilitate telestenting over greater geographic distances.

To assess the feasibility of delivering and evaluating a lifestyle programme for patients with colorectal cancer undergoing potentially curative treatments. Non-randomised feasibility trial. National Health Service (NHS) Tayside. Adults with stage I-III colorectal cancer. The programme targeted smoking, alcohol, physical activity, diet and weight management. It was delivered in three face-to-face counselling sessions (plus nine phone calls) by lifestyle coaches over three phases (1: presurgery, 2: surgical recovery and 3: post-treatment recovery). Feasibility measures (recruitment, retention, programme implementation, achieved measures, fidelity, factors affecting protocol adherence and acceptability). Measured changes in body weight, waist circumference, walking and self-reported physical activity, diet, smoking, alcohol intake, fatigue, bowel function and quality of life. Of 84 patients diagnosed, 22 (26%) were recruited and 15 (18%) completed the study. Median time for intervention delivery was 5.5 hours. Coaches reported covering most (>70%) of the intervention components but had difficulties during phase 2. Evaluation measures (except walk test) were achieved by all participants at baseline, and most (<90%) at end of phase 2 and phase 3, but <20% at end of phase 1. Protocol challenges included limited time between diagnosis and surgery and the presence of comorbidities. The intervention was rated highly by participants but limited support from NHS staff was noted. The majority of participants (77%) had a body mass index>25 kg/m 2 and none was underweight. Physical activity data showed a positive trend towards increased activity overall, but no other changes in secondary outcomes were detected. To make this intervention feasible for testing as a full trial, further research is required on (a) recruitment optimisation, (b) appropriate assessment tools, (c) protocols for phase 2 and 3, which can build in flexibility and (d) ways for NHS staff to facilitate the programme.

Objective To develop a feasibility study of a theory-driven telephone counseling program to enhance psychosocial and physical well-being for cancer survivors after treatment. Methods Participants (n = 66) were recruited from two Colorado hospitals with self-administered questionnaires at baseline and two weeks post-intervention. The one group, intervention only design included up to six thematic telephone counseling sessions over three months. Topics included nutrition, physical activity, stress management, and medical follow-up. Primary outcomes were cancer-specific distress, self-reported fruit and vegetable consumption and physical activity. Results Of 66 subjects, 46 completed at least one counseling module and the follow-up assessment (70% retention rate). Mean satisfaction was 9 out of 10, and all participants would recommend C-STEPS to other survivors. Cancer-specific distress (Impact of Event Scale – Intrusion subscale) decreased for entire study population (p < 0.001) and stress management session participants (p < 0.001). Fruit and vegetable consumption increased for nutrition and exercise session participants (p = 0.02) and the entire sample (p = NS). Physical activity increased in the entire group (p = 0.006) and for nutrition and exercise session participants (p = 0.01). Conclusion and practice implications C-STEPS is a feasible telephone counseling program that transcends geographic barriers, demonstrating the potential to decrease distress and promote coping and healthy lifestyles among cancer survivors.

Regular physical activity reduces the risk of many diseases and improves physical and mental health. However, physical inactivity is widespread globally. Improving physical activity levels is a global concern in well-being management. Exercise performance measurement systems have the potential to improve physical activity by providing feedback and motivation to users. We propose an exercise performance measurement system for well-being management that is based on the accumulated activity effective index (AAEI) and incorporates a smartphone-embedded sensor. The proposed system generates a numeric index that is based on users’ exercise performance: their level of physical activity and number of days spent exercising. The AAEI presents a clear number that can serve as a useful feedback and goal-setting tool. We implemented the exercise performance measurement system by using a smartphone and conducted experiments to assess the feasibility of the system and investigated the user experience. We recruited 17 participants for validating the feasibility of the measurement system and a total of 35 participants for investigating the user experience. The exercise performance measurement system showed an overall precision of 88% in activity level estimation. Users provided positive feedback about their experience with the exercise performance measurement system. The proposed system is feasible and has a positive effective on well-being management.

Assessment of physical fitness is important in order to set goals, appropriately prescribe exercise, and monitor change over time. This study aimed to determine the utility of a standardized physical fitness assessment for use in cancer-specific, community-based exercise programs. Tests anticipated to be feasible and suitable for a community setting and a wide range of ages and physical function were chosen to measure body composition, aerobic fitness, strength, flexibility, and balance. Cancer Exercise Trainers/Specialists at cancer-specific, community-based exercise programs assessed new clients (n = 60) at enrollment, designed individualized exercise programs, and then performed a re-assessment 3-6 months later (n = 34). Resting heart rate, blood pressure, body mass index, waist circumference, handgrip strength, chair stands, sit-and-reach, back scratch, single-leg standing, and timed up-and-go tests were considered suitable and feasible tests/measures, as they were performed in most (≥88 %) participants. The ability to capture change was also noted for resting blood pressure (-7/-5 mmHg, p = 0.02), chair stands (+4, p < 0.01), handgrip strength (+2 kg, p < 0.01), and sit-and-reach (+3 cm, p = 0.03). While the submaximal treadmill test captured a meaningful improvement in aerobic fitness (+62 s, p = 0.17), it was not completed in 33 % of participants. Change in mobility, using the timed up-and-go was nominal and was not performed in 27 %. Submaximal treadmill testing, handgrip dynamometry, chair stands, and sit-and-reach tests were feasible, suitable, and provided meaningful physical fitness information in a cancer-specific, community-based, exercise program setting. However, a shorter treadmill protocol and more sensitive balance and upper body flexibility tests should be investigated.

A pilot study of yoga as self-care for arthritis in minority communities

PubMed Central

2013-01-01

Background While arthritis is the most common cause of disability, non-Hispanic blacks and Hispanics experience worse arthritis impact despite having the same or lower prevalence of arthritis compared to non-Hispanic whites. People with arthritis who exercise regularly have less pain, more energy, and improved sleep, yet arthritis is one of the most common reasons for limiting physical activity. Mind-body interventions, such as yoga, that teach stress management along with physical activity may be well suited for investigation in both osteoarthritis and rheumatoid arthritis. Yoga users are predominantly white, female, and college educated. There are few studies that examine yoga in minority populations; none address arthritis. This paper presents a study protocol examining the feasibility and acceptability of providing yoga to an urban, minority population with arthritis. Methods/design In this ongoing pilot study, a convenience sample of 20 minority adults diagnosed with either osteoarthritis or rheumatoid arthritis undergo an 8-week program of yoga classes. It is believed that by attending yoga classes designed for patients with arthritis, with racially concordant instructors; acceptability of yoga as an adjunct to standard arthritis treatment and self-care will be enhanced. Self-care is defined as adopting behaviors that improve physical and mental well-being. This concept is quantified through collecting patient-reported outcome measures related to spiritual growth, health responsibility, interpersonal relations, and stress management. Additional measures collected during this study include: physical function, anxiety/depression, fatigue, sleep disturbance, social roles, and pain; as well as baseline demographic and clinical data. Field notes, quantitative and qualitative data regarding feasibility and acceptability are also collected. Acceptability is determined by response/retention rates, positive qualitative data, and continuing yoga practice after three months. Discussion There are a number of challenges in recruiting and retaining participants from a community clinic serving minority populations. Adopting behaviors that improve well-being and quality of life include those that integrate mental health (mind) and physical health (body). Few studies have examined offering integrative modalities to this population. This pilot was undertaken to quantify measures of feasibility and acceptability that will be useful when evaluating future plans for expanding the study of yoga in urban, minority populations with arthritis.

Breast cancer survivors are at risk for poor health, with physical activity a possible treatment. Little research has examined how technology might promote breast cancer survivor physical activity or health. The aim of this study is to investigate the feasibility of employing a commercially available mobile health application- and social media-based health education intervention to improve breast cancer survivor physical activity or health.Ten breast cancer survivors (X̅ age = 45.80 ± 10.23 years; X̅ weight = 79.51 ± 20.85 kg) participated in this 10-week single-group pilot study from 2015 to 2016. Participants downloaded the MapMyFitness application, documented all physical activity with MapMyFitness, and were enrolled in a Social Cognitive Theory-based, Facebook-delivered health education intervention. Objectively measured physical activity, weight or body composition, cardiovascular fitness, psychosocial constructs, and quality of life indices were measured at baseline and 10 weeks. Intervention use and acceptability was evaluated during and following the intervention. Descriptive statistics were calculated for all study outcomes, with qualitative analyses performed regarding use and acceptability. At postintervention, average daily moderate-to-vigorous physical activity and steps increased by 2.6 min and 1,657, respectively, with notable decreases in weight (2.4 kg) and body fat percentage (2.3%). Physical activity-related social support and ability to engage in social roles or activity demonstrated the greatest improvements among all psychosocial and quality of life indices, respectively. Participants enjoyed the feedback and tracking features of MapMyFitness, with most finding the Facebook component helpful. All participants recommended the intervention for future use.Physical activity interventions combining commercially available mobile health applications and theoretically based social media-delivered health interventions may promote certain physiological, psychosocial, and quality of life outcomes among breast cancer survivors. Larger samples and randomized studies are warranted.

There is increasing recognition that exercise is an efficacious strategy for managing many consequences of multiple sclerosis (MS), yet persons with MS are not engaging in sufficient exercise for accruing health benefits. Poor exercise uptake might be associated with the design of previous research. We conducted a randomised controlled trial (RCT) for examining the feasibility of a 4-month home-based, exercise-training program designed based on recent physical activity guidelines for MS and supplemented by behavioural strategies for compliance. Feasibility was assessed in the domains of process (e.g., recruitment), resource (e.g., monetary costs), management (e.g., personnel time requirements) and scientific outcomes (e.g., treatment effect). We recruited persons with mild-to-moderate MS who were randomised into an intervention or wait-list control condition. Intervention participants received a pedometer, elastic resistance bands, DVD, training manual, calendars, log-book, video coaching calls and newsletters. Participants in both conditions completed home-based assessments before and after the 4-month period. Ninety-nine persons with MS were assessed for eligibility, and 57 were randomised. Fifty-one persons completed the study (90%). Total costs of the study were US $5331.03. Personnel time to conduct the study totaled 263h. Participants in the intervention group complied fully with 71% of all exercise sessions. There was a moderate increase in self-reported exercise behaviour of the intervention participants as measured by the Godin Leisure-Time Exercise Questionnaire (d≥0.5). The results support the feasibility and acceptability of a home-based exercise intervention based on physical activity guidelines and supplemented with behavioural strategies for adults with mild-to-moderate MS.

This pilot study examined the feasibility outcome recruitment, safety and compliance of the investigation for stochastic resonance whole-body vibration (SR-WBV) training. Another aim was to evaluate the effect size of one SR-WBV intervention session on Short Physical Performance Battery (SPPB), Expanded Timed Get Up-and-Go (ETGUG), isometric maximal voluntary contraction (IMVC) and rate of force development (IRFD) and chair rising (CR). Randomised double-blinded controlled cross-over pilot study. Feasibility outcomes included recruitment, safety and compliance. For secondary outcomes, SPPB, ETGUG, IMVC, IRFD and CR were measured before and 2-min after intervention. Nonparametric Rank-Order Tests of Puri and Sen L Statistics to Ranked Data were proposed. Wilcoxon signed-ranked tests were used to analyse the differences after SR-WBV intervention and sham intervention. Treatment effects between the interventions were compared by a Mann-Whitney U test. Among 24 eligible frail elderly, 12 agreed to participate and 3 drop out. The adherence was 15 of 24 intervention sessions. For secondary outcome, effect sizes (ES) for SR-WBV intervention on SPPB, ETGUG and CR were determined. This pilot study indicate that the training protocol used in this form for frail elderly individuals is feasible but with modification due to the fact that not all defined feasibility outcomes target was met. SR-WBV with 6 Hz, noise level 4 shows benefit improvements on SPPB (ES 0.52), ETGUG (part sit-to-stand movement: ES 0.81; total time: ES 0.85) and CR (ES 0.66). Further research is desired to determine whether a new adapted training protocol is necessary for SR-WBV in the "skilling up" phase in frail elderly individuals.

The Muon Accelerator Program (MAP) has completed a four-year study on the feasibility of muon colliders and on using stored muon beams for neutrinos. That study was broadly successful in its goals, establishing the feasibility of heavy lepton colliders (HLCs) from the 125 GeV Higgs Factory to more than 10 TeV, as well as exploring using a μ storage ring (MSR) for neutrinos, and establishing that MSRs could provide factory-level intensities of νe (more » $$\\bar{ve}$$) and $$\\bar{vμ}$$ (νμ) beams. The key components of the collider and neutrino factory systems were identified. Feasible designs and detailed simulations of all of these components have been obtained, including some initial hardware component tests, setting the stage for future implementation where resources are available and the precise physics goals become apparent.« less

The prevalence of pediatric obesity has increased over the past 3 decades and is a pressing public health program. New technology advancements that can encourage more physical in children are needed. The Zamzee program is an activity meter linked to a motivational website designed for children 8-14 years of age. The objective of the study was to use a collaborative approach between a medical center, the private sector and local school staff to assess the feasibility of using the Zamzee Program in the school-based setting to improve physical activity levels in children. This was a pilot 8-week observational study offered to all children in one fifth grade classroom. Body mass index (BMI), the amount of physical activity by 3-day recall survey, and satisfaction with usability of the Zamzee Program were measured pre- and post-study. Out of 11 children who enrolled in the study, 7 completed all study activities. In those who completed the study, the median (interquartile range) total activity time by survey increased by 17 (1042) minutes and the BMI percentile change was 0 (8). Both children and their caregivers found the Zamzee Activity Meter (6/7) and website (6/7) "very easy" or "easy" to use. The Zamzee Program was found to be usable but did not significantly improve physical activity levels or BMI. Collaborative obesity intervention projects involving medical centers, the private sector and local schools are feasible but the effectiveness needs to be evaluated in larger-scale studies.

This study is a feasibility test of whether incorporating trauma-sensitive yoga into group therapy for female victims of partner violence improves symptoms of anxiety, depression, and posttraumatic stress disorder (PTSD) beyond that achieved with group therapy alone. Seventeen (9 control, 8 intervention) adult female clients seeking group psychotherapy were enrolled. A 12-week trauma-sensitive yoga protocol was administered once weekly for 30–40 min at the end of each group therapy session. The control group received typical group psychotherapy. Feasibility was assessed through recruitment and retention rates as well as participants’ self-reported perceptions of the safety and utility of the study. The study enrolled 85% (17/20) of those screened eligible. Loss to follow-up was 30% (5/17). No one reported emotional or physical harm. All of the respondents reported that the study was personally meaningful and that the results would be useful to others. PMID:25129883

2004-01-01

A study was conducted that shows how a single Radioisotope Electric Propulsion (REP) spacecraft design could be used for various missions throughout the solar system. This spacecraft design is based on a REP feasibility design from a study performed by NASA Glenn Research Center and the Johns Hopkins University Applied Physics Laboratory. The study also identifies technologies that need development to enable these missions. The mission baseline for the REP feasibility design study is a Trojan asteroid orbiter. This mission sends an REP spacecraft to Jupiter s leading Lagrange point where it would orbit and examine several Trojan asteroids. The spacecraft design from the REP feasibility study would also be applicable to missions to the Centaurs, and through some change of payload configuration, could accommodate a comet sample-return mission. Missions to small bodies throughout the outer solar system are also within reach of this spacecraft design. This set of missions, utilizing the common REP spacecraft design, is examined and required design modifications for specific missions are outlined.

Gait is a common focus of physical therapists' management of patients in acute care settings. Walking speed, the distance a patient covers per unit time, has been advocated as a "sixth vital sign." However, the feasibility of measuring walking speed and the degree to which walking speed is limited or improves over the course of therapy in the acute care setting are unclear. The purpose of this study of patients undergoing physical therapy during acute care hospitalization, therefore, was to determine whether walking speed can be measured in acute care and whether walking speed is limited and changes over the course of therapy. This was an observational cross-sectional study. Participants were 46 hospital inpatients, mean age 75.0 years (SD = 7.8), referred to physical therapy and able to walk at least 20 ft. Information regarding diagnosis, comorbidities, physical assistance, device use, body height, and weight was obtained. Speed was determined during initial and final physical therapy visits while patients walked at their self-selected speed over a marked course in a hospital corridor. Therapists reported that walking speed was clinically feasible, requiring inexpensive, available resources, 4 minutes' additional time, and simple calculations for documentation. Initial walking speed was a mean of 0.33 m/s (SD = 0.21; 95% confidence interval [CI]: 0.27-0.39), whereas final speed was 0.37 m/s (SD = 0.20; 95% CI: 0.31-0.43). The Wilcoxon test showed the increase in walking speed (0.04 m/s) to be significant (P = .005) over a mean therapy period of 2.0 days (SD = 1.4) and total hospitalization period of 5.5 days (SD = 3.6). The effect size and standardized response mean were 0.19 and 0.36, respectively. Minimal detectable change was 0.18 m/s. Walking speed is a feasible measure for patients admitted to an acute care hospital. It shows that patients walk slowly relative to community requirements but that their speed improves even over a short course of therapy.

As life expectancy increases and the number of older people, particularly those aged 85 years and over, expands there is an increase in demand for long-term care. A large proportion of people in a care home setting spend most of their time sedentary, and this is one of the leading preventable causes of death. Encouraging residents to engage in more physical activity could deliver benefits in terms of physical and psychological health, and quality of life. This study is the final stage of a programme of research to develop and preliminarily test an evidence-based intervention designed to enhance opportunities for movement amongst care home residents, thereby increasing levels of physical activity. This is a cluster randomised feasibility trial, aiming to recruit at least 8-12 residents at each of 12 residential care homes across Yorkshire, UK. Care homes will be randomly allocated on a 1:1 basis to receive either the intervention alongside usual care, or to continue to provide usual care alone. Assessment will be undertaken with participating residents at baseline (prior to care home randomisation) and at 3, 6, and 9 months post-randomisation. Data relating to changes in physical activity, physical function, level of cognitive impairment, mood, perceived health and wellbeing, and quality of life will be collected. Data at the level of the home will also be collected and will include staff experience of care, and changes in the numbers and types of adverse events residents experience (for example, hospital admissions, falls). Details of National Health Service (NHS) usage will be collected to inform the economic analysis. An embedded process evaluation will obtain information to test out the theory of change underpinning the intervention and its acceptability to staff and residents. This feasibility trial with embedded process evaluation and collection of health economic data will allow us to undertake detailed feasibility work to inform a future large-scale trial. It will provide valuable information to inform research procedures in this important but challenging area. ISRCTN registry, ISRCTN16076575 . Registered on 25 June 2015.

Laughter Yoga consists of physical exercise, relaxation techniques and simulated vigorous laughter. It has been associated with physical and psychological benefits for people in diverse clinical and non-clinical settings, but has not yet been tested in a haemodialysis setting. The study had three aims: 1) to examine the feasibility of conducting Laughter Yoga for patients with end stage kidney disease in a dialysis setting; 2) to explore the psychological and physiological impact of Laughter Yoga for these patients; and 3) to estimate the sample size required for future research. Pre/post intervention feasibility study. Eighteen participants were recruited into the study and Laughter Yoga therapists provided a four week intradialytic program (30-min intervention three times per week). Primary outcomes were psychological items measured at the first and last Laughter Yoga session, including: quality of life; subjective wellbeing; mood; optimism; control; self-esteem; depression, anxiety and stress. Secondary outcomes were: blood pressure, intradialytic hypotensive episodes and lung function (forced expiratory volume). Dialysis nurses exposed to the intervention completed a Laughter Yoga attitudes and perceptions survey (n = 11). Data were analysed using IBM SPSS Statistics v22, including descriptive and inferential statistics, and sample size estimates were calculated using G*Power. One participant withdrew from the study for medical reasons that were unrelated to the study during the first week (94 % retention rate). There were non-significant increases in happiness, mood, and optimism and a decrease in stress. Episodes of intradialytic hypotension decreased from 19 pre and 19 during Laughter Yoga to 4 post Laughter Yoga. There was no change in lung function or blood pressure. All nurses agreed or strongly agreed that Laughter Yoga had a positive impact on patients' mood, it was a feasible intervention and they would recommend Laughter Yoga to their patients. Sample size calculations for future research indicated that a minimum of 207 participants would be required to provide sufficient power to detect change in key psychological variables. This study provides evidence that Laughter Yoga is a safe, low-intensity form of intradialytic physical activity that can be successfully implemented for patients in dialysis settings. Larger studies are required, however, to determine the effect of Laughter Yoga on key psychological variables. Australian New Zealand Clinical Trials Registry - ACTRN12614001130651 .

Advance Care Planning (ACP) and its documentation, accessible to healthcare professionals regardless of where patients are staying, can improve palliative care. ACP is usually performed by trained facilitators. However, ACP conversations would be more tailored to a patient's specific situation if held by a patient's clinical healthcare team. This study assesses the feasibility of ACP by a patient's clinical healthcare team, and analyses the documented information including current and future problems within the palliative care domains. This multicentre study was conducted at the three Groningen Palliative Care Network hospitals in the Netherlands. Patients discharged from hospital with a terminal care indication received an ACP document from clinical staff (non-palliative care trained staff at hospitals I and II; specialist palliative care nurses at hospital III) after they had held ACP conversations. An anonymised copy of this ACP document was analysed. Documentation rates of patient and contact details were investigated, and documentation of current and future problems were analysed both quantitatively and qualitatively. One hundred sixty ACP documents were received between April 2013 and December 2014, with numbers increasing for each consecutive 3-month time period. Advance directives were frequently documented (82%). Documentation rates of current problems in the social (24%), psychological (27%) and spiritual (16%) domains were low compared to physical problems (85%) at hospital I and II, but consistently high (> 85%) at hospital III. Of 545 documented anticipated problems, 92% were physical or care related in nature, 2% social, 5% psychological, and < 1% spiritual. Half of the anticipated non-physical problems originated from hospital III. Hospital-initiated ACP documentation by a patient's clinical healthcare team is feasible: the number of documents received per time period increased throughout the study period, and overall, documentation rates were high. Nonetheless, symptom documentation predominantly regards physical symptoms. With the involvement of specialist palliative care nurses, psychological and spiritual problems are addressed more frequently. Whether palliative care education for non-palliative care experts will improve identification and documentation of non-physical problems remains to be investigated.

Despite recent interest in the potential of incentivisation as a strategy for motivating healthier behaviors, little remains known about the effectiveness of incentives in promoting physical activity and reducing sedentary behavior, and improving associated health outcomes. This pre-post-test design study investigated the feasibility, appeal and effects of providing non-financial incentives for promoting increased physical activity, reduced sedentary time, and reduced body mass index (BMI) and blood pressure among inactive middle-aged adults. Inactive men (n = 36) and women (n = 46) aged 40-65 years were recruited via a not-for-profit insurance fund and participated in a 4 month pre-post design intervention. Baseline and post-intervention data were collected on self-reported physical activity and sitting time (IPAQ-Long), BMI and blood pressure. Participants were encouraged to increase physical activity to 150 mins/week and reduce sedentary behavior by 150 mins/week in progressive increments. Incentives included clothing, recipe books, store gift vouchers, and a chance to win one of four Apple iPad Mini devices. The incentive component of the intervention was supported by an initial motivational interview and text messaging to encourage participants and provide strategies to increase physical activity and reduce sedentary behaviors. Only two participants withdrew during the program, demonstrating the feasibility of recruiting and retaining inactive middle-aged participants. While two-thirds of the sample qualified for the easiest physical activity incentive (by demonstrating 100 mins physical activity/week or 100 mins reduced sitting time/week), only one third qualified for the most challenging incentive. Goals to reduce sitting appeared more challenging, with 43% of participants qualifying for the first incentive, but only 20% for the last incentive. More men than women qualified for most incentives. Mean leisure-time physical activity increased by 252 mins/week (leisure-time), with 65% of the sample achieving at least 150 mins/week; and sitting time decreased by 3.1 h/day (both p < 0.001) between baseline and follow-up. BMI, systolic and diastolic (men only) blood pressure all significantly decreased. Most participants (50-85%) reported finding the incentives and other program components helpful/motivating. Acknowledging the uncontrolled design, the large pre-post changes in behavioral and health-related outcomes suggest that the ACHIEVE incentives-based behavior change program represents a promising approach for promoting physical activity and reducing sitting, and should be tested in a randomized controlled trial.

Childhood obesity is a major public health problem, with one third of America's children classified as either overweight or obese. Obesity prevention and health promotion programs using components such as wellness coaching and home-based interventions have shown promise, but there is a lack of published research evaluating the impact of a combined home-based and wellness coaching intervention for obesity prevention and health promotion in young girls. The main objective of this study is to test the feasibility of such an intervention on metrics related to recruitment, intervention delivery, and health-related outcome assessments. The secondary outcome is to evaluate the possibility of change in health-related psychosocial, behavioral, and biomedical outcomes in our sample of participants. Forty girls who are overweight or obese (aged 8-13 years) will be recruited from a Midwestern college town. Participants will be recruited through posted flyers, newspaper advertisements, email, and social media. The volunteer convenience sample of girls will be randomized to one of two home-based wellness coaching interventions: a general health education condition or a healthy eating physical activity skills condition. Trained female wellness coaches will conduct weekly hour-long home visits for 12 consecutive weeks. Assessments will occur at baseline, post-intervention (3 months after baseline), and follow-up (6 months after baseline) and will include height, weight, waist circumference, body composition, pulmonary function, blood pressure, systemic inflammation, physical activity (Actical accelerometer), and self-reported survey measures (relevant to fruit and vegetable consumption, physical activity, and quality of life). This study will evaluate the feasibility of home-based wellness coaching interventions for overweight and obese girls and secondarily assess the preliminary impact on health-related psychosocial, behavioral, and biomedical outcomes. Results will provide information regarding the feasibility of this new model for use in girls as an approach to reduce the burden of overweight and obesity toward the prevention of chronic disease.

To assess the feasibility of a new intervention, Ready~Steady, in terms of demand, acceptability, implementation, and limited efficacy. Randomized controlled trial; repeated measures. Two rural communities in Itasca County, Minnesota. Thirty participants were randomized to an intervention (n = 16) or attention-control (n = 14) group. Ready~Steady combined two components: (1) motivational (motivational support, social network support, empowering education), and (2) fall-reducing physical activities (PAs; guidance to practice leg-strengthening, balance, and flexibility activities and walking). Acceptability questionnaire and Indices of Procedural Consistency (investigator developed), Community Health Activity Model Program for Seniors Questionnaire (confirmed with accelerometry), Short Physical Performance Battery, Perceived Environmental Support Scale, Social Support for Exercise Questionnaire, Goal Attainment Scale, Index of Readiness, and Index of Self-Regulation. Descriptive statistics and a marginal approach to repeated-measures analysis of variance, using mixed-model procedures. Attrition was 7% and mean attendance was 7.2 of 8 sessions, participants evaluated Ready~Steady as acceptable, and implementation fidelity was good. The intervention group improved significantly more than the attention-control group in PA behavior, F 1,27 = 11.92, p = .002; fall risk (functional balance and strength), F 1,27 = 14.89, p = .001; support for exercise from friends, F 1,27 = 11.44, p = .002; and self-regulation, F 1,26 = 38.82, p < .005. The Ready~Steady intervention was feasible as evidenced by low attrition and good attendance and implementation, as well as positive effects on targeted outcomes and theoretical mechanisms of change. © 2016 by American Journal of Health Promotion, Inc.

Development and feasibility testing of an intervention to support active lifestyles in youths with type 1 diabetes-the ActivPals programme: a study protocol.

The global incidence of type 1 diabetes is rising, and youths with type 1 diabetes continue to suffer poorer health than peers without diabetes. Evidence suggests youths with type 1 diabetes have physical activity (PA) levels well below the recommendations for health and have high levels of sedentary behaviour. An active lifestyle is therefore recommended to improve health. There is limited research showing effective lifestyle behaviour change in this population; therefore, an evidence gap exists between the need to promote physical activity in type 1 diabetes care and lack of understanding on how to do this. This protocol paper describes a feasibility and pilot study of the ActivPals programme-an intervention to support active lifestyles in youths with type 1 diabetes. Key intervention components have been identified from preliminary work (individual and family focus, peer mentoring, technology integration and improved communication and understanding) and are being developed into a pragmatic randomised controlled trial (RCT) supported by recruitment pathways. A steering group of health care professionals and managers will refine the intervention to patient needs. A pilot trial is providing data on intervention implementation, acceptability and feasibility. Twenty youths with type 1 diabetes are being recruited and randomised into an intervention or control group. Physical activity is being measured objectively using the Actigraph GT3X+ monitor at baseline and 1-month follow-up. Contextual factors associated with intervention delivery are being explored. This study will contribute to the development of evidence-based, user-informed and pragmatic interventions leading to healthier lifestyles in youths with type 1 diabetes.

Assessing the feasibility, acceptability, and potential effectiveness of a behavioral-automaticity focused lifestyle intervention for African Americans with metabolic syndrome: The Pick two to Stick to protocol.

Metabolic syndrome (MetS) significantly increases the risk of developing diabetes and cardiovascular disease. Being physically active and eating a healthy diet can reduce MetS risk factors. Too frequently, however, studies report that the effects of interventions targeting those factors are not maintained once interventions are withdrawn. A potential solution to the problem is targeting behavioral automaticity (habit-development) to aid in initiation and maintenance of health-behavior changes. The Pick two to Stick To (P2S2), is an 8-week, theory-based hybrid (face-to-face/telecoaching) habit focused lifestyle intervention designed to increase healthful physical activity and dietary behavioral automaticity. The purpose of this article is to describe the rationale and protocol for evaluating the P2S2 program's feasibility, acceptability and potential effectiveness. Using a prospective, non-comparative design, the P2S2 program will be implemented by trained occupational therapy 'coaches' to 40 African Americans aged 40 and above with MetS recruited from the emergency department. Semi-structured interviews with participants, bi-weekly research meetings with study staff, and observations of intervention delivery will provide data for a process evaluation. Estimates of effectiveness include weight, blood pressure, waist circumference, BMI, and behavioral automaticity measures that will be collected at baseline and week 20. The P2S2 program could facilitate the development of healthful dietary and physical activity habits in an underserved population. Whether interventions aimed at changing habits can feasibly influence this automaticity, particularly for high-risk, low resource communities where other barriers exist, is not known. This pilot study, therefore, will fill an important gap, providing insight to inform subsequent trials.

The objective was to determine the safety, feasibility, and effects of anti-gravity gait training on functional outcomes (Knee Injury and Osteoarthritis Outcome Score [KOOS], the Timed Up and Go test [TUG], Numerical Rating Scale [NRS] for pain) with the AlterG® Anti-Gravity Treadmill® device for total knee arthroplasty (TKA) rehabilitation. Subjects (N = 30) were randomized to land-based vs anti-gravity gait training over 4 weeks of physical therapy after TKA. Adverse events, complications, and therapist satisfaction were recorded. All patients completed rehabilitation protocols without adverse events. KOOS, TUG, and NRS scores improved in both groups with no significant differences between groups. For the AlterG group, Sports/Recreation and Quality of Life subscales of the KOOS had the most improvement. At the end of physical therapy, TUG and NRS pain scores improved from 14 seconds to 8 seconds and from 2.8 to 1.1, respectively. Subjectively, therapists reported 100% satisfaction with the AlterG. This initial pilot study demonstrated that the AlterG Anti-Gravity Treadmill device was safe and feasible. While functional outcomes improved over time with use of the anti-gravity gait training, further studies are needed to define the role of this device as an alternative or adjunct to established rehabilitation protocols.

An overview of the Gas-Grain Simulation Facility (GGSF) project and its current status is provided. The proceedings of the Gas-Grain Simulation Facility Experiments Workshop are recorded. The goal of the workshop was to define experiments for the GGSF--a small particle microgravity research facility. The workshop addressed the opportunity for performing, in Earth orbit, a wide variety of experiments that involve single small particles (grains) or clouds of particles. Twenty experiments from the fields of exobiology, planetary science, astrophysics, atmospheric science, biology, physics, and chemistry were described at the workshop and are outlined in Volume 2. Each experiment description included specific scientific objectives, an outline of the experimental procedure, and the anticipated GGSF performance requirements. Since these experiments represent the types of studies that will ultimately be proposed for the facility, they will be used to define the general science requirements of the GGSF. Also included in the second volume is a physics feasibility study and abstracts of example Gas-Grain Simulation Facility experiments and related experiments in progress.

Low levels of physical activity have been reported in South Asian Muslim women. Mosques could be beneficial in providing physical activity opportunities for Muslim women. This study examined the feasibility, acceptability and effectiveness of a mosque-based physical activity program for South Asian Muslim women in Canada. Sixty-two South Asian Muslim women participated in a 24-week mosque-based exercise intervention. Feasibility, acceptability and effectiveness of the program was evaluated by pre-post survey questions from the Duke Activity Status Index (DASI) and International Physical Activity Questionnaire among 28 women who consented to the research data collection. Nineteen women were assessed pre-and post-intervention. The women demonstrated increase in median scores of self-efficacy (90 pre vs. 100 post; p = 0.004) and the importance of engaging in regular physical activity (90 pre vs. 100 post; p = 0.01). Fewer participants were classified as inactive at the end of the intervention (42 % pre vs. 10 % post; p = 0.006). There was a mean increase in DASI scores (39.2 pre vs. 44.6 post; p = 0.06) reflecting an improvement in peak aerobic capacity and functional quality of life. Culturally relevant structured networks such as mosques are important assets when designing healthy lifestyle interventions for South Asian Muslim women.

Latinas in the US report high levels of physical inactivity and are disproportionally burdened by related health conditions (eg, type 2 diabetes, obesity), highlighting the need for innovative strategies to reduce these disparities. A 1-month single-arm pretest-posttest design was utilized to assess the feasibility and acceptability of a culturally and linguistically adapted Internet-based physical activity intervention for Spanish-speaking Latinas. The intervention was based on the Social Cognitive Theory and the Transtheoretical Model. Changes in physical activity and related psychosocial variables were measured at baseline and the end of the 1-month intervention. The sample included 24 Latina adults (mean age, 35.17±11.22 years). Most (83.3%) were born outside the continental US. Intent-to-treat analyses showed a significant increase (P=.001) in self-reported moderate- to vigorous-intensity physical activity from a median of 12.5 min/wk at baseline to 67.5 min/wk at the 1-month assessment. Participants reported significant increases in self-efficacy as well as cognitive and behavioral processes of change. Nearly half of the participants (45.8%) reported advancing at least one stage of change during the course of the 1-month intervention. Findings support the feasibility and acceptability of using interactive Internet-based technology to promote physical activity among Latinas in Alabama.

This study assessed the interest of alternative high school staff in intervention research on students' eating and physical activity habits and the feasibility of conducting such research in alternative school settings. A two-phase descriptive design incorporated both quantitative and qualitative methods. In fall/winter 2001-2002, alternative high school administrators in Minnesota were surveyed (response rate = 83%; n = 130/157). During summer 2002, one-on-one, semistructured interviews were conducted with key school personnel (n = 15) from urban and suburban schools. Findings indicated few schools had been invited to participate in research on nutrition (11%) and physical activity (7%). However, more than 80% of administrators reported interest in their students participating in such research. Most schools offered health and PE classes and had access to indoor gym facilities and outdoor play areas. While most schools offered a school lunch program, participation was low, cold lunches were common, and food often was unappealing. Beverage and snack vending machines were common. Overall, the physical environment of most alternative schools did not support physical activity and healthy eating as normative behavior. Interest in interventions on physical inactivity, unhealthy dietary practices, and other priority health-risk behavior common in students attending alternative schools was high among teachers and administrators. Results suggest research in alternative high schools is feasible and successful implementation and evaluation of programs possible.

Institutionalized children in low-income countries often face maltreatment and inadequate caregiving. In addition to prior traumatization and other childhood adversities in the family of origin, abuse and neglect in institutional care are linked to various mental health problems. By providing a manualized training workshop for caregivers, we aimed at improving care quality and preventing maltreatment in institutional care. In Study 1, 29 participating caregivers rated feasibility and efficacy of the training immediately before, directly after, and 3 months following the training workshop. The results showed high demand, good feasibility, high motivation, and acceptance of caregivers. They reported improvements in caregiver-child relationships, as well as in the children's behavior. Study 2 assessed exposure to maltreatment and the mental health of 28 orphans living in one institution in which all caregivers had been trained. The children were interviewed 20 months before, 1 month before, and 3 months after the training. Children reported a decrease in physical maltreatment and assessments showed a decrease in mental health problems. Our approach seems feasible under challenging circumstances and provides first hints for its efficacy. These promising findings call for further studies testing the efficacy and sustainability of this maltreatment prevention approach.

Physical activity levels are low amongst adolescent girls, and this population faces specific barriers to being active. Peer influences on health behaviours are important in adolescence and peer-led interventions might hold promise to change behaviour. This paper describes the protocol for a feasibility cluster randomised controlled trial of Peer-Led physical Activity iNtervention for Adolescent girls (PLAN-A), a peer-led intervention aimed at increasing adolescent girls' physical activity levels. A two-arm cluster randomised feasibility trial will be conducted in six secondary schools (intervention n  = 4; control n  = 2) with year 8 (12-13 years old) girls. The intervention will operate at a year group level and consist of year 8 girls nominating influential peers within their year group to become peer-supporters. Approximately 15 % of the cohort will receive 3 days of training about physical activity and interpersonal communication skills. Peer-supporters will then informally diffuse messages about physical activity amongst their friends for 10 weeks. Data will be collected at baseline (time 0 (T0)), immediately after the intervention (time 1 (T1)) and 12 months after baseline measures (time 2 (T2)). In this feasibility trial, the primary interest is in the recruitment of schools and participants (both year 8 girls and peer-supporters), delivery and receipt of the intervention, data provision rates and identifying the cost categories for future economic analysis. Physical activity will be assessed using 7-day accelerometry, with the likely primary outcome in a fully-powered trial being daily minutes of moderate-to-vigorous physical activity. Participants will also complete psychosocial questionnaires at each time point: assessing motivation, self-esteem and peer physical activity norms. Data analysis will be largely descriptive and focus on recruitment, attendance and data provision rates. The findings will inform the sample size required for a definitive trial. A detailed process evaluation using qualitative and quantitative methods will be conducted with a variety of stakeholders (i.e. pupils, parents, teachers and peer-supporter trainers) to identify areas of success and necessary improvements prior to proceeding to a definitive trial. This paper describes the protocol for the PLAN-A feasibility cluster randomised controlled trial which will provide the information necessary to design a fully-powered trial should PLAN-A demonstrate evidence of promise.

The feasibility and acceptability of conducting a trial of specialist medical care and the Lightning Process in children with chronic fatigue syndrome: feasibility randomized controlled trial (SMILE study)

PubMed Central

2013-01-01

Background Chronic fatigue syndrome (CFS) or myalgic encephalomyelitis (ME) is relatively common in children with limited evidence for treatment. The Phil Parker Lightning Process (LP) is a trademarked intervention, which >250 children use annually. There are no reported studies investigating the effectiveness or possible side effects of LP. Methods The trial population was drawn from the Bath and Bristol NHS specialist paediatric CFS or ME service. The study was designed as a pilot randomized trial with children (aged 12 to 18 years) comparing specialist medical care with specialist medical care plus the Lightning Process. Integrated qualitative methodology was used to explore the feasibility and acceptability of the recruitment, randomization and interventions. Results A total of 56 children were recruited from 156 eligible children (1 October 2010 to 16 June 2012). Recruitment, randomization and both interventions were feasible and acceptable. Participants suggested changes to improve feasibility and acceptability and we incorporated the following in the trial protocol: stopped collecting 6-week outcomes; introduced a second reminder letter; used phone calls to collect primary outcomes from nonresponders; informed participants about different approaches of each intervention and changed our recommendation for the primary outcome for the full study from school attendance to disability (SF-36 physical function subscale) and fatigue (Chalder Fatigue Scale). Conclusions Conducting randomized controlled trials (RCTs) to investigate an alternative treatment such as LP is feasible and acceptable for children with CFS or ME. Feasibility studies that incorporate qualitative methodology enable changes to be made to trial protocols to improve acceptability to participants. This is likely to improve recruitment rate and trial retention. Trial registration Feasibility study first randomization: 29 September 2010.

Silicon tracking detectors operated at high luminosity collider experiments pose a challenge for current and future readout systems regarding bandwidth, radiation, space and power constraints. With the latest developments in wireless communications, wireless readout systems might be an attractive alternative to commonly used wired optical and copper based readout architectures. The WADAPT group (Wireless Allowing Data and Power Transmission) has been formed to study the feasibility of wireless data transmission for future tracking detectors. These proceedings cover current developments focused on communication in the 60 GHz band. This frequency band offers a high bandwidth, a small form factor and an already mature technology. Motivation for wireless data transmission for high energy physics application and the developments towards a demonstrator prototype are summarized. Feasibility studies concerning the construction and operation of a wireless transceiver system have been performed. Data transmission tests with a transceiver prototype operating at even higher frequencies in the 240 GHz band are described. Data transmission at rates up to 10 Gb/s have been obtained successfully using binary phase shift keying.

Adherence to rehabilitation exercise is much lower in patients with hematologic malignancies (22.5-45.8%) than in patients with solid tumors (60-85%) due to the administration of more intensive chemotherapeutic regimens in the former. Virtual reality exercise can be performed even in a biological clean room and it may improve the adherence rates in elderly patients with hematologic malignancies. Thus, in this pilot study, we aimed to investigate the feasibility and safety of virtual reality exercise intervention using Nintendo Wii Fit in patients with hematologic malignancies receiving chemotherapy. In this feasibility study, 16 hospitalized patients with hematologic malignancies aged ≥60 years performed virtual reality exercise for 20 minutes using the Nintendo Wii Fit once a day, five times a week, from the start of chemotherapy until hospital discharge. The adherence rate, safety, and physical and psychological performances were assessed. The adherence rate for all 16 patients was 66.5%. Nine patients completed the virtual reality exercise intervention with 88 sessions, and the adherence rate was 62.0%. No intervention-related adverse effects >Grade 2, according to National Cancer Institute Common Terminology Criteria for Adverse Events version 3.0, were observed. We noted maintenance of the physical performance (e.g., Barthel index, handgrip strength, knee extension strength, one-leg standing time, and the scores of timed up and go test and Instrumental Activities of Daily Living) and psychosocial performance (e.g., score of hospital anxiety and depression scale). Virtual reality exercise using the Wii Fit may be feasible, safe and efficacious, as demonstrated in our preliminary results, for patients with hematologic malignancies receiving chemotherapy.

Mental health settings are recognized as complex, unpredictable environments, and challenging interpersonal situations are common for nurses in acute adult mental health services. Occupational stressors include verbal aggression and physical assault and are correlated with poor physical and mental health outcomes for nurses. There is a clear need for proactive approaches that address the negative impacts of stressors on the mental health nursing workforce. Resilience interventions are a preventive approach to strengthening skills for addressing workplace stress, improving health and well-being, and preventing adverse outcomes associated with occupational stressors. The aim of this study was to evaluate the feasibility of a workplace resilience education programme for nurses in high-acuity adult mental health settings. The outcomes were measured using a single-group pretest post-test design with follow-up at 3 months postintervention. The feasibility and acceptability of the programme were identified with descriptors of mental health, well-being, resilience, facilitator fidelity checklists, and participant satisfaction questionnaires. The programme was found to be feasible for nurses working in high-acuity inpatient settings. There were significant changes to mental health, well-being, and workplace resilience. The programme was delivered with fidelity by facilitators and accepted with high levels of satisfaction by participants. The study findings indicated that nurses can benefit from resilience education that equips them with cognitive, emotion regulation, and relational skills, in conjunction with available external supports and resources, to address workplace challenges. There is a need for comprehensive organizational approaches that include individual, work unit, and organizational-level strategies to support staff well-being. © 2018 Australian College of Mental Health Nurses Inc.

Cystic fibrosis (CF) causes high illness burden. Screening may identify patients who could potentially benefit from interventions for symptoms or other sources of distress. We evaluated the feasibility of a web-based system for routine monitoring. Adult CF patients enrolled in a study of palliative care service delivery completed web-based assessments every 30 days on global distress, physical and psychological symptom distress, and the perceived benefits of discussing advance care planning (ACP) with CF clinicians. Feasibility was assessed by the rate of survey completion, survey reminders, and missed surveys during a 9-month rolling enrollment period. Of 74 participants (47.3% women, 94.4% white), 36.7% had comorbid diabetes, and 56.9% had an FEV1% predicted score of 40-69. In total, patients completed 456 (80.6%) of 566 surveys every 30 days over the assessment period. Sixty-five (87.8%) completed 405 (79.7%) of 508 surveys online and 9 (12.2%) completed 51 (88.0%) of 58 surveys using a combination of online, telephone, and mail-based methods. Many surveys were completed without reminders (online: 261 [64.4%] of 405; combined methods: 29 [56.9%] of 51), with 166 (36.4%) surveys requiring 1 or more reminders. Further, 23.0% (17) of patients noted elevated global distress; 20.3% (15) endorsed physical symptom distress, 12.2% (9) had psychological distress, and 58.1% (43) reported that discussing ACP would be beneficial. Repeated web-based screening for symptom distress and ACP preferences is feasible in adult CF patients. Future studies should assess the system's generalizability and staff resources when implementing reminders and non-web methods of completion. Copyright © 2015 European Cystic Fibrosis Society.

Background Childhood obesity has reached epidemic proportions in developed countries. Sedentary screen-based activities such as video gaming are thought to displace active behaviors and are independently associated with obesity. Active video games, where players physically interact with images onscreen, may have utility as a novel intervention to increase physical activity and improve body composition in children. The aim of the Electronic Games to Aid Motivation to Exercise (eGAME) study is to determine the effects of an active video game intervention over 6 months on: body mass index (BMI), percent body fat, waist circumference, cardio-respiratory fitness, and physical activity levels in overweight children. Methods/Design Three hundred and thirty participants aged 10–14 years will be randomized to receive either an active video game upgrade package or to a control group (no intervention). Discussion An overview of the eGAME study is presented, providing an example of a large, pragmatic randomized controlled trial in a community setting. Reflection is offered on key issues encountered during the course of the study. In particular, investigation into the feasibility of the proposed intervention, as well as robust testing of proposed study procedures is a critical step prior to implementation of a large-scale trial.

Objective To perform translation, cross-cultural adaptation, and validation of the Penn Acoustic Neuroma Quality-of-Life Scale (PANQOL) to the Spanish language. Study Design Prospective study. Setting Tertiary neurotologic referral center. Subjects and Methods PANQOL was translated and translated back, and a pretest trial was performed. The study included 27 individuals diagnosed with vestibular schwannoma. Inclusion criteria were adults with untreated vestibular schwannoma, diagnosed in the past 12 months. Feasibility, internal consistency, test-retest reliability, construct validity, and ceiling and floor effects were assessed for the present study. Results The mean overall score of the PANQOL was 69.21 (0-100 scale, lowest to highest quality of life). Cronbach's α was 0.87. Intraclass correlation coefficient was performed for each item, with an overall score of 0.92. The κ coefficient scores were between moderate and almost perfect in more than 92% of patients. Anxiety and energy domains of the PANQOL were correlated with both physical and mental components of the SF-12. Hearing, balance, and pain domains were correlated with the SF-12 physical component. Facial and general domains were not significantly correlated with any component of the SF-12. Furthermore, the overall score of the PANQOL was correlated with the physical component of the SF-12. Conclusion Feasibility, internal consistency, reliability, and construct validity outcomes in the current study support the validity of the Spanish version of the PANQOL.

The purpose of this pilot quasi-experimental study was to examine the feasibility and preliminary efficacy of using Facebook in a 10-week lifestyle intervention with Head Start caregiver-preschooler dyads to improve healthy behaviors and reduce body mass index. Sixty-nine dyads participated with 39 in the intervention group. Average preschooler attendance rate for the Head Start center-based program was 77%, and caregiver participation rate was 87%. About 94% of the caregivers were satisfied with the program, and 97% would recommend the program to others and/or participate again. The intervention decreased preschoolers' body mass index z score (Cohen's d = -.30) and screen time ( d = -.21), and increased their fruit and vegetable intake ( d = .40) and moderate-to-vigorous physical activity ( d = .42). The intervention increased caregivers' fruit and vegetable intake ( d = .40). The intervention is feasible, and preliminary efficacy is encouraging, but further investigation using a rigorous study design is warranted.

This pilot study questions the effects of a worksite physical activity program on health and fitness in tertiary employees. Ninety-five employees were randomly assigned to Control (CON); Novice (NOV); Experienced group (EXP). The NOV and EXP groups followed a 5-month worksite physical activity program (at least two sessions/week). Body composition, physical activity level and physical fitness, eating habits, health perception, sleep quality, pain, and quality of life were assessed. Fat mass decreased in NOV and EXP; the distance covered during the 6-minute walking test, push-ups, squat jump increased for NOV and EXP group. Physical activity level, health perception, quality of sleep, and eating habits were improved in NOV. This study underlines for the first time the beneficial effects of such worksite programs among tertiary employees on overall health and the feasibility of its design.

The objective of this study was to determine the feasibility (i.e., limited efficacy testing, practicality, and acceptability) of a 6-week smartphone game-based applications program for promoting physical activity (PA) in adolescents in an afterschool program. This mixed-method, quasi-experimental design study included 27 adolescents who evaluated four smartphone PA game-based applications in two Boys & Girls Clubs of America. After an initial baseline week (i.e., usual activity during their visit to the Club), adolescents played each game for 1 week. During a final week, the participants could choose to play any combination of the four games. An established conceptual framework was used to assess feasibility. Efficacy was assessed by changes in PA via wrist-worn accelerometers (model GT3x+; ActiGraph LLC, Pensacola, FL). Practicality was measured through field notes, the number of players attending each session, and the proportion of attendees who played the games. Acceptability was measured using poststudy focus groups. Compared with baseline (3.22 metabolic equivalents [METs]), mean accelerometer values were significantly (P<0.05) higher during "Space Rayders" (4.33 METs) and "Color Hunt" (3.67 METs). Attendance did not differ among games, and weekly number of players averaged 12 of 27 participants. Qualitative findings indicated that participants perceived "Space Rayders" as the most acceptable game. Overall, participants found the games to be enjoyable and easy to use, although they had suggestions to improve graphics and sounds. Smartphone games can be feasible for adolescents to use for PA. Lessons learned will be used to provide improvements for future game development and evaluation.

As people live longer, their risk of disability increases. Disability affects quality of life and increases health and social care costs. Preventing or delaying disability is therefore an important objective, and identifying an effective intervention could improve the lives of many older people. Observational and interventional evidence suggests that physical activity may reduce the risk of age-related disability, as assessed by physical performance measures. However it is unclear what approach is the most cost-effective intervention in changing long-term physical activity behaviour in older adults. A new theory-driven behavioural intervention has been developed, with the aim of increasing physical activity in the everyday lives of older adults at risk of disability. This pilot study tests the feasibility and acceptability of delivering this intervention to older adults. A randomised controlled trial (RCT) design will be used in the pilot study. Sixty patients aged 65 years and older will be recruited from primary care practices. Patients will be eligible to participate if they are inactive, not disabled at baseline, are at risk of developing disability in the future (Short Physical Performance Battery score <10/12), and have no contraindications to physical activity. Following baseline measures, participants will be randomised in a 2:1 ratio to the intervention or to a control arm and all participants will be followed-up after 6 months. Those randomised to the intervention arm will receive sessions with a trained Physical Activity Facilitator, delivering an intervention based on self-determination theory. Control participants receive a booklet on healthy ageing. The main outcomes of interest are recruitment, adherence, retention and acceptability. Data will also be collected on: self-report and accelerometer-recorded physical activity; physical performance; depression; wellbeing; cognitive function; social support; quality of life, healthcare use, and attitudes to physical activity. A mixed-methods process evaluation will run alongside the RCT. The intervention, if effective, has the potential to reduce disability and improve quality of life in older adults. Before proceeding to a full-scale trial a pilot trial is necessary to ensure intervention feasibility and acceptability, and that the intervention shows evidence of promise.

Yoga is a holistic therapy of expanding popularity, which has the potential to produce a range of physical, mental and social benefits. This trial evaluated the feasibility and effects of an adapted yoga programme on physical function and health-related quality of life in physically-inactive older adults. In this randomised controlled pilot trial, 52 older adults (90% female; mean age 74.8 years, SD 7.2) were randomised 1:1 to a yoga programme or wait-list control. The yoga group (n = 25) received a physical activity education booklet and were invited to attend ten yoga sessions during a 12-week period. The control group (n = 27) received the education booklet only. Measures of physical function (e.g., Short Physical Performance Battery; SPPB), health status (EQ-5D) and mental well-being (Warwick-Edinburgh Mental Well-being Scale; WEMWBS) were assessed at baseline and 3 months. Feasibility was assessed using course attendance and adverse event data, and participant interviews. Forty-seven participants completed follow-up assessments. Median class attendance was 8 (range 3 to 10). At the 3-month follow-up, the yoga group had a higher SPPB total score compared with the control group (mean difference 0.9, 95% confidence interval [CI] -0.3 to 2.0), a faster time to rise from a chair five times (mean difference - 1.73 s, 95% CI -4.08 to 0.62), and better performance on the chair sit-and-reach lower-limb flexibility test (mean difference 5 cm, 95% CI 0 to 10). The yoga group also had superior health status and mental well-being (vs. control) at 3 months, with mean differences in EQ-5D and WEMWBS scores of 0.12 (95% CI, 0.03 to 0.21) and 6 (95% CI, 1 to 11), respectively. The interviews indicated that participants valued attending the yoga programme, and that they experienced a range of benefits. The adapted yoga programme appeared to be feasible and potentially beneficial in terms of improving mental and social well-being and aspects of physical function in physically-inactive older adults. An appropriately-powered trial is required to confirm the findings of the present study and to determine longer-term effects. ClinicalTrials.gov NCT02663726 .

“Pre-schoolers in the playground” an outdoor physical activity intervention for children aged 18 months to 4 years old: study protocol for a pilot cluster randomised controlled trial

PubMed Central

2013-01-01

Background The pre-school years are considered critical for establishing healthy lifestyle behaviours such as physical activity. Levels of physical activity track through childhood into adulthood, thus establishing habitual physical activity early in life is vital. Time spent outdoors is associated with greater physical activity and playground interventions have been shown to increase physical activity in school aged children. There are few pre-school, playground-based interventions, and evaluations of these have found mixed results. A recent report published by the UK Chief Medical Officer (CMO) highlighted that new interventions to promote movement in the early years (0–5 years old) are needed. The aim of this study is to undertake a pilot cluster randomised controlled trial (RCT) of an outdoor playground-based physical activity intervention for parents and their children aged 18 months to 4 years old (“Pre-schoolers in the Playground”; PiP) and to assess the feasibility of conducting a full scale cluster RCT. The PiP intervention is grounded in behavioural theory (Social Cognitive Theory), and is in accordance with the CMO guidance for physical activity in the early years. It is informed by existing literature and data collected from focus groups with parents. Methods/Design One hundred and fifty pre-school children affiliated to 10 primary schools will be recruited. Schools will be randomised to either the PiP intervention arm or the control arm (usual practice). Children in the intervention arm will be invited to attend three 30 minute outdoor play sessions per week for 30 weeks (3 school terms) at the school. Feasibility will be assessed by examining recruitment rates, attendance, attrition, acceptability of the trial and of the PiP intervention to parents, fidelity of intervention implementation, capability and capacity for schools to deliver the intervention. Health outcomes and the feasibility of outcome measurement tools will be assessed. These include physical activity via triaxial, accelerometry (Actigraph GT3X+), anthropometry (height, body mass, BMI, waist and upper arm circumference), health related quality of life for child (PedsQL) and parent (EQ5D), parent wellbeing (ComQol-A5), injuries and health service use. A health economic evaluation will also be undertaken. Discussion It is anticipated that results of this pilot trial will be published in spring 2015.

African-American (AA) women are the segment of the population that experiences the highest mortality from metabolic syndrome (MetS). Yoga decreases risk of MetS, yet there have been no yoga studies of AA women with or at risk for MetS. The purpose of this 4-week study was to test the feasibility and acceptability of a culturally tailored, Internet-based intervention, yogic dance (YD), using digital videos in a sample of AA women (ages 35-64) at risk for or with MetS. The investigators examined the rates of accrual, attrition, and reasons for attrition; the feasibility of using the Internet to deliver the intervention; the acceptability of the intervention as structured; and any other benefits and/or limitations of YD. The study used a single-group, mixed-methods design underpinned by social constructivist theory and Pender's Health Promotion Model. Twenty-four women provided consent to enroll in the study. After completing in-person semi-structured interviews and Internet-based measures, including the Physical Activity Readiness Questionnaire, and the modified International Physical Activity Questionnaire, consented participants engaged in 4-weeks of the yogic dance intervention via daily video-based instructions located on the study Web site. After the intervention, four women participated in focus groups to voice their perceptions of barriers to and benefits from YD and the acceptability of using the YD intervention. The investigators analyzed focus group data using content/thematic analysis and validated themes with baseline semi-structured interviews. The majority of the women (79%) found YD acceptable. Themes that emerged from the descriptive data include: (1) Culture is an important aspect of yogic dance; and (2) Increased social support would enhance yogic dance participation. The integrated results from this feasibility study will inform research exploring the complex correlates that influence health behaviors in AA women. PMID:25593785

Is Home-Based, High-Intensity Interval Training Cycling Feasible and Safe for Patients With Knee Osteoarthritis?: Study Protocol for a Randomized Pilot Study.

PubMed

Keogh, Justin W L; Grigg, Josephine; Vertullo, Christopher J

2017-03-01

Osteoarthritis (OA) is a degenerative joint disease affecting the knee joint of many middle-aged and older adults. As OA symptoms typically involve knee pain and stiffness, individuals with knee OA are often insufficiently physically active, have low levels of physical function, and are at increased risk of other comorbidities and reduced quality of life. While moderate-intensity continuous training (MICT) cycling is often recommended, little is known about the feasibility, safety, and benefits of high-intensity interval training (HIIT) cycling for this population, even though the feasibility, safety, and benefits of HIIT have been demonstrated in other chronic disease groups. The primary objective of this pilot study was to examine the feasibility and safety of home-based HIIT and MICT cycling in middle-aged and older adults with knee OA. A secondary objective was to gain some insight into the relative efficacy of HIIT and MICT for improving health status (pain, stiffness, and disability), muscle function, and body composition in this population. This study protocol is being published separately to allow a detailed description of the research methods, explain the rationale for choosing the methodological details, and to stimulate consideration of the best means to simulate a research protocol that is relevant to a real-life treatment environment. Randomized pilot study protocol. This trial sought to recruit 40 middle-aged and older adults with knee OA. Participants were randomly allocated to either continuous (MICT) or HIIT home-based cycle training programs, with both programs requiring the performance of 4 cycling sessions (approximately 25 minutes per session) each week. Participants were measured at baseline and postintervention (8 weeks). Feasibility and safety were assessed by adherence rate, dropout rate, and number of adverse events. The relative efficacy of the cycling programs was investigated by 2 knee OA health status questionnaires (Western Ontario and McMaster Universities Osteoarthritis Index scale[WOMAC] and the Lequesne Index) as well as the timed up and go, sit to stand, preferred gait speed, and body composition. This pilot study appears to be the first study assessing the feasibility and safety of a home-based HIIT training program for middle-aged and older adults with knee OA. As HIIT has been demonstrated to be more effective than MICT for improving aspects of health status, body composition, and/or muscular function in other chronic disease groups, the current study has the potential to improve patient outcomes and inform the design of future randomized controlled trials.

Background Participation in physical activity has a positive impact on the overall health and quality of life, whereas physical inactivity is associated with a poor prognosis among breast cancer survivors. Despite the health-enhancing benefits of physical activity, the majority of Malaysian breast cancer survivors are not physically active. This paper presents the design of a randomised study to evaluate the feasibility and effect of exercise therapy intervention using light resistance dumbbell exercise to promote active lifestyle and improve the quality of life of breast cancer survivors in Malaysia. Methods/design This is an intervention study of a 12-week exercise therapy that will explore and compare the effects of light resistance and aerobic exercise on physical activity level and quality of life components in 102 female breast cancer survivors. Major eligibility criteria include histologically confirmed diagnosis of breast cancer stages I–III, 3–12 months post-diagnosis, and absence of any disorder contraindicating exercise. Participants will be stratified based on menopausal status (pre-menopause vs post-menopause) and then assigned randomly to one of three groups. Participants in group A will participate in a three-times weekly supervised resistance exercise using light resistance dumbbells; participants in group B will participate in a three-times weekly supervised aerobic exercise; while participants in group C (control group) will be given aerobic exercise after completion of the intervention. The primary end points include physical activity level and quality of life components. The secondary end points are body mass index, body composition, total caloric intake, and waist-to-hip ratio. Discussion Although there have been many studies of resistance exercise in breast cancer survivors, this is the first study using this specific mode of resistance. Findings will contribute data on the feasibility and effects of light resistance dumbbell exercises, and provide knowledge on the physical activity intervention programme that will maximally promote better overall health and well-being of survivors.

To use a Delphi panel to determine the relative importance and feasibility of workplace health promotion interventions to promote and support the health of the Australian nursing and midwifery workforce. The nursing workforce experiences rates of ill health above that of other workforces, yet there is little investment in workplace health promotion. The study used a modified Delphi design conducted between September and November 2015. Eleven of 19 purposively selected expert panellists discussed, rated and provided feedback through two rounds of an electronic questionnaire about the relative importance and feasibility of 46 workplace health promotion interventions and processes for nurses and midwives. Scores for importance and feasibility were calculated and ranked and a composite score of importance multiplied by feasibility. Mental health strategies were prioritized as the most important and feasible of the intervention topics, followed closely by healthy eating and physical activity interventions; smoking cessation ranked lowest. The most highly ranked interventions targeted healthy eating, stress management and resilience training. Highest ranked processes to support development of a healthy work environment included intersectoral collaboration and employee wellness groups. Study findings prompt consideration of health promotion opportunities to support nurses' health and well-being. Findings identified key workplace health promotion priorities and provide direction for policy makers and managers to promote nursing and midwifery workforce health. © 2017 John Wiley & Sons Ltd.

Comment on 'Deep convolutional neural network with transfer learning for rectum toxicity prediction in cervical cancer radiotherapy: a feasibility study'.

PubMed

The application of machine learning (ML) presents tremendous opportunities for the field of oncology, thus we read 'Deep convolutional neural network with transfer learning for rectum toxicity prediction in cervical cancer radiotherapy: a feasibility study' with great interest. In this article, the authors used state of the art techniques: a pre-trained convolutional neural network (VGG-16 CNN), transfer learning, data augmentation, drop out and early stopping, all of which are directly responsible for the success and the excitement that these algorithms have created in other fields. We believe that the use of these techniques can offer tremendous opportunities in the field of Medical Physics and as such we would like to praise the authors for their pioneering application to the field of Radiation Oncology. That being said, given that the field of Medical Physics has unique characteristics that differentiate us from those fields where these techniques have been applied successfully, we would like to raise some points for future discussion and follow up studies that could help the community understand the limitations and nuances of deep learning techniques.

Quantum Physics Principles and Communication in the Acute Healthcare Setting: A Pilot Study.

PubMed

Helgeson, Heidi L; Peyerl, Colleen Kraft; Solheim-Witt, Marit

This pilot study explores whether clinician awareness of quantum physics principles could facilitate open communication between patients and providers. In the spirit of action research, this study was conceptualized with a holistic view of human health, using a mixed method design of grounded theory as an emergent method. Instrumentation includes surveys and a focus group discussion with twelve registered nurses working in an acute care hospital setting. Findings document that the preliminary core phenomenon, energy as information, influences communication in the healthcare environment. Key emergent themes include awareness, language, validation, open communication, strategies, coherence, incoherence and power. Research participants indicate that quantum physics principles provide a language and conceptual framework for improving their awareness of communication and interactions in the healthcare environment. Implications of this pilot study support the feasibility of future research and education on awareness of quantum physics principles in other clinical settings. Copyright © 2016 Elsevier Inc.

Regular physical activity has important health benefits for children with type 1 diabetes mellitus (T1DM), yet children and their parents face barriers to participation such as lack of self-efficacy or concerns around hypoglycaemia. Multimedia interventions are useful for educating children about their health and demonstrate potential to improve children's health-related self-efficacy, but few paediatric clinics offer web-based resources as part of routine care. The Steps to Active Kids with Diabetes (STAK-D) programme is an online intervention grounded in psychological theory (social cognitive theory) and informed by extensive preliminary research. The aim of the programme is to encourage and support safe engagement with physical activity for children with T1DM. The aim of this research is to explore the feasibility of delivering the STAK-D programme to children aged 9-12 years with T1DM, and to assess the feasibility of further research to demonstrate its clinical and cost-effectiveness. Up to 50 children aged 9-12 years with T1DM and their parents will be recruited from two paediatric diabetes clinics in the UK. Child-parent dyads randomised to the intervention group will have access to the intervention website (STAK-D) and a wrist-worn activity monitor for 6 months. The feasibility of intervention and further research will be assessed by rate of recruitment, adherence, retention, data completion and adverse events. Qualitative interviews will be undertaken with a subsample of children and parents (up to 25 dyads) and health care professionals (up to 10). Health outcomes and the feasibility of outcome measurement tools will be assessed. These include self-efficacy (CSAPPA), objective physical activity, self-reported physical activity (PAQ), fear of hypoglycaemia (CHFS; PHFS), glycaemic control (HbA1c), insulin dose, Body Mass Index (BMI), health-related quality of life (CHU9D; CHQ-PF28), health service use and patient-clinician communication. Assessments will be taken at baseline (T0), 8 weeks (T1) and at 6-month follow-up (T2). The goal of this feasibility trial is to assess the delivery of STAK-D to promote physical activity among children with T1DM, and to assess the potential for further, definitive research to demonstrate its effectiveness. Results will provide the information necessary to design a larger randomised controlled trial and maximise the recruitment rate, intervention delivery and trial retention. ISRCTN, ISRCTN48994721 .

The Volunteering-in-Place (VIP) Program was developed to provide individualized meaningful volunteer activities matched to interests and capabilities for older adults with MCI in assisted living. The purposes of this single-site pre-test/post-test pilot study were to (1) establish feasibility of the VIP Program based on treatment fidelity (design, treatment, delivery, enactment); and (2) evaluate preliminary efficacy via improvement in psychological health (depressive symptoms, usefulness, purpose, resilience, and life satisfaction) and decreased sedentary activity (survey and Fitbit) at 3 and 6 months. Ten residents participated. The majority was white, female and educated, and on average 88 years old. The VIP Program was feasible and most participants continued to volunteer at 6 months. There were non-significant improvements in depressive symptoms, usefulness, purpose, resilience and recreational physical activity. The results of this study provide support for the feasibility of the VIP Program. Further study is necessary to examine efficacy. Copyright © 2016 Elsevier Inc. All rights reserved.

To determine the feasibility and efficacy of a physical activity behavioural change intervention in managing cancer-related fatigue among gynaecological cancer survivors during and post anti-cancer treatments. A two arm, single blind, randomised controlled trial was conducted within the Northern Ireland regional Cancer Centre. Thirty three sedentary gynaecological cancer survivors (stage I-III; ≤3 years post diagnosis), experiencing cancer-related fatigue (mild-severe) took part. Participants were randomly assigned to a behavioural change, moderate intensity physical activity intervention (n=16) or a Contact Control group (n=17). The primary outcome was fatigue (Multidimensional Fatigue Symptom Inventory-Short Form and Functional Assessment in Chronic Illness Therapy-Fatigue subscale). Secondary outcomes included quality of life, physical functioning, positive and negative affect, depression, body composition, sleep dysfunction and self-reported physical activity. Feasibility was assessed based on the recruitment rate, programme and physical activity adherence and participants' programme evaluation, including optional focus groups (n=16). Twenty five percent of eligible women took part (33/134). Participants were 8.7 (SD=9.1) months post diagnosis, with a mean age of 53 (SD=10.3) years. The majority of the sample had a diagnosis of ovarian (n=12) or endometrial cancer (n=11). Significant differences favouring the intervention group were observed for fatigue at 12 weeks and 6 months follow-up (12 week: mean difference=-11.06; 95% confidence interval (CI)=-21.89 to -0.23; effect size (d)=0.13; p=0.046; 6 month: mean difference=-19.48; 95% CI=-19.67 to -19.15; effect size (d)=0.20; p=0.01). A mean of 10 calls (SD=1.2 calls) were delivered to the Physical Activity Group, and 10 (SD=1.6 calls) to the CC group. The intervention was positively perceived based on exit questionnaire and focus group findings. A physical activity behavioural change intervention for gynaecological cancer survivors is feasible in terms of participants' programme adherence and evaluation, and the intervention demonstrates improvements in fatigue. However, confirmation in the form of a larger fully powered RCT is warranted. Copyright © 2011 Elsevier Inc. All rights reserved.

For individuals, especially older adults, playing video games is a promising tool for improving their driving skills. The ease of use, wide availability, and interactivity of gaming consoles make them an attractive simulation tool. The objective of this study was to look at the feasibility and effects of installing video game consoles in the homes of individuals looking to improve their driving skills. A systematic literature review was conducted to assess the effect of playing video games on improving driving skills. An observatory study was performed to evaluate the feasibility of using an Xbox 360 Kinect console for improving driving skills. Twenty-nine articles, which discuss the implementation of video games in improving driving skills were found in literature. On our study, it was found the Xbox 360 with Kinect is capable of improving physical and mental activities. Xbox Video games were introduced to engage players in physical, visual and cognitive activities including endurance, postural sway, reaction time, eyesight, eye movement, attention and concentration, difficulties with orientation, and semantic fluency. However, manual dexterity, visuo-spatial perception and binocular vision could not be addressed by these games. It was observed that Xbox Kinect (by incorporating Kinect sensor facilities) combines physical, visual and cognitive engagement of players. These results were consistent with those from the literature review. From the research that has been carried out, we can conclude that video game consoles are a viable solution for improving user's physical and mental state. In future we propose to carry a thorough evaluation of the effects of video games on driving skills in elderly people.

Overweight, obesity and excess gestational weight gain (GWG) are associated with negative health outcomes for mother and child in pregnancy and across the life course. Interventions promoting GWG within guidelines report mixed results. Most are time and cost intensive, which limits scalability. Mobile technologies (mHealth) offer low cost, ready access and individually-tailored support. We aim to test the feasibility of an mHealth intervention promoting healthy nutrition, physical activity and GWG in women who begin pregnancy overweight or obese. txt4two is a parallel randomised control trial pilot recruiting women with a singleton, live gestation between 10(+0) and 17(+6) weeks at the first hospital antenatal clinic visit. Inclusion criteria are pre-pregnancy BMI > 25 kg/m(2) and mobile phone ownership. One hundred consenting women will be randomised to intervention or control groups at a 1:1 ratio. All participants will receive standard antenatal care. In addition, the txt4two intervention will be delivered from baseline to 36 weeks gestation and consists of a tailored suite of theoretically-grounded, evidence-based intervention strategies focusing on healthy nutrition, physical activity and GWG. This includes: mobile phone interactive text messages promoting positive health behaviours, goal setting and self-monitoring; video messages; an information website; and a private moderated Facebook® chat forum. The primary outcome is the feasibility of the intervention. Secondary outcomes include GWG and participants' knowledge and behaviour regarding diet and physical activity during pregnancy. Findings will inform the development of larger-scale mHealth programmes to improve the delivery of healthy pregnancy nutrition, physical activity and GWG, that could be widely translated and disseminated.

Toddlerhood is an important age for physical activity (PA) promotion to prevent obesity and support a physically active lifestyle throughout childhood. Accurate assessment of PA is needed to determine trends/correlates of PA, time spent in sedentary, light, or moderate-vigorous PA (MVPA), and the effectiveness of PA promotion programs. Due to the limited availability of objective measures that have been validated and evaluated for feasibility in community studies, it is unclear which subgroups of toddlers are at the highest risk for inactivity. Using Actical ankle accelerometry, the objectives of this study are to develop valid thresholds, examine feasibility, and examine demographic/ anthropometric PA correlates of MVPA among toddlers from low-income families. Two studies were conducted with toddlers (12-36 months). Laboratory Study (n = 24)- Two Actical accelerometers were placed on the ankle. PA was observed using the Child Activity Rating Scale (CARS, prescribed activities). Analyses included device equivalence reliability (correlation: activity counts of two Acticals), criterion-related validity (correlation: activity counts and CARS ratings), and sensitivity/specificity for thresholds. Community Study (n = 277, low-income mother-toddler dyads recruited)- An Actical was worn on the ankle for > 7 days (goal >5, 24-h days). Height/weight was measured. Mothers reported demographics. Analyses included frequencies (feasibility) and stepwise multiple linear regression (sMLR). Laboratory Study- Acticals demonstrated reliability (r = 0.980) and validity (r = 0.75). Thresholds demonstrated sensitivity (86 %) and specificity (88 %). Community Study- 86 % wore accelerometer, 69 % had valid data (mean = 5.2 days). Primary reasons for missing/invalid data: refusal (14 %) and wear-time ≤2 days (11 %). The MVPA threshold (>2200 cpm) yielded 54 min/day. In sMLR, MVPA was associated with age (older > younger, β = 32.8, p < 0.001), gender (boys > girls, β = -11.21, p = 0.032), maternal MVPA (β = 0.44, p = 0.002) and recruitment location (suburban > urban, β = 19.6, p < 0.001), or race (non-Black > Black, β = 18.5, p = 0.001). No association with toddler weight status. Ankle accelerometry is a valid, reliable, and feasible method of assessing PA in community studies of toddlers from low-income families. Sub-populations of toddlers may be at increased risk for inactivity, including toddlers that are younger, female, Black, those with less active mothers, and those living in an urban location.

Chronic diseases are high in truck drivers and have been linked to work routines that promote inactivity and poor diets. This feasibility study examined the extent to which an m-Health financial incentives program facilitated physical activity and healthy dietary choices in Australian truck drivers. Nineteen men (mean [SD] age = 47.5 [9.8] years; BMI = 31.2 [4.6] kg/m 2 ) completed the 20-week program, and used an activity tracker and smartphone application (Jawbone UP™) to regulate small positive changes in occupational physical activity, and fruit, vegetable, saturated fat and processed/refined sugar food/beverage choices. Measures (baseline, end-program, 2-months follow-up; April-December 2014) were accelerometer-determined proportions of work time spent physically active, and a workday dietary questionnaire. Statistical (repeated measures ANOVA) and thematic (interviews) analyses assessed program impact. Non-significant increases in the mean proportions of work time spent physically active were found at end-program and follow-up (+1%; 7 mins/day). Fruit (p = 0.023) and vegetable (p = 0.024) consumption significantly increased by one serve/day at end-program. Non-significant improvements in saturated fat (5%) and processed/refined sugar (1%) food/beverage choices were found at end-program and follow-up. Overall, 65% (n = 11) of drivers demonstrated positive changes in physical activity, and at least one dietary choice (e.g. saturated fat) at follow-up. Drivers found the financial incentives component of the program to be a less effective facilitator of change than the activity tracker and smartphone application, although this technology was easier to use for monitoring of physical activity than healthy dietary choices. Not all drivers benefitted from the program. However, positive changes for different health behaviours were observed in the majority of participants. Outcomes from this feasibility study inform future intervention development for studies with larger samples. ANZCTR12616001513404 . Registered November 2nd, 2016 (retrospectively registered).

Pilot test GoWoman, a small-group weight management intervention for mobility impaired women that was a disability- and gender-responsive adaptation of the Diabetes Prevention Program delivered in the online virtual world of Second Life ® . Objectives were to (1) examine pre-/post-intervention differences in weight, waist circumference, diet, physical activity, self-efficacy for diet and physical activity, nutrition knowledge and social support for weight management, (2) determine intervention feasibility (fidelity, attrition, engagement, acceptability). Single-group modified interrupted time series quasi-experimental design whereby participants served as their own controls. Thirteen women attended ≥8 of 16 GoWoman weekly sessions and lost an average of 5.97 pounds (2.71 kg) (3.31%) body weight (Cohen's d = 0.74) and 1.44 inches (3.66 cm) (3.58%) waist circumference (Cohen's d = 0.83). There were significant improvements in physical activity, diet and self-efficacy for diet and physical activity. All benchmarks for feasibility were met. Ratings of intervention content, group interactions and support and virtual world experiences were highly positive. Findings suggest that a disability- and gender-responsive weight management intervention with peer group support delivered in an online virtual world is feasible, meaningful and may assist with weight management for mobility impaired women. Implications for Rehabilitation This study addresses a gap in the general and rehabilitation research literature by addressing the disproportionately high rates of obesity among women with mobility impairments, who are generally excluded from tests of weight management interventions if they have limited ability to engage in vigorous physical activity. The GoWoman program is an adaptation of the Diabetes Prevention Program Lifestyle Change curriculum that is tailored to meet the unique weight management needs of women with mobility impairments, and was created to become a publicly available, disability- and gender-responsive intervention that can be used in community and rehabilitation settings. More rehabilitation and health promotion program should be offered in the free, online, virtual world of Second Life ® since participants in this pilot study offered many favorable comments about the new learning and social opportunities available to them there and they did not have to deal with the disability-related environmental and health challenges that often prevent them from participating in face-to-face workshops. Preliminary indications of improvements in body weight, waist circumference, diet and physical activity after attending the GoWoman weight management intervention offered in Second Life ® tell us that these strategies are feasible for helping women with mobility impairments manage their weight and should undergo further testing.

Athletes often record details of their training and competitions, supported by information such as environmental conditions, travel, as well as how they felt. However, it is not known how prevalent these practices are in golfers, or how valuable this process is perceived. The purpose of this study was to develop a golf-specific load monitoring tool (GLMT), and establish the content validity and feasibility of this tool amongst high-level golfers. In the first phase of development, 21 experts were surveyed to determine the suitability of items for inclusion in the GLMT. Of the 36 items, 21 received >78% agreement, a requirement to establish content validity and for inclusion in the GLMT. Total duration was the preferred metric for golf-specific activities, whilst rating of perceived exertion (RPE) was preferred for measuring physical training. In the second phase, feasibility of the tool was assessed by surveying 13 high-level male golfers following 28-days of daily GLMT use. All items included in the GLMT were deemed feasible to record, with all players participating in the feasibility study providing high to very high ratings. Golfers responded that they would consider using a load monitoring tool of this nature long term, provided it can be completed in less than five minutes per day.

The scientific evidence supporting pulmonary rehabilitation (PR) for lung cancer patients undergoing cytotoxic chemotherapy is accumulating; however, the feasibility of outpatient-based PR in these patients has not yet been evaluated in Korea. We conducted an eight-week outpatient-based PR feasibility study in a tertiary referral hospital setting. Patients with advanced lung cancer (non-small cell lung cancer IIIB-IV and small-cell lung cancer extensive disease) scheduled to undergo first-line cytotoxic chemotherapy underwent PR consisting of 60-minute sessions twice a week under the guidance and supervision of a physical therapist, for a total of eight weeks. Feasibility was assessed based on completion of the PR program. In total, 12 patients (median age 68 years) were enrolled; 11 (91.7%) were male with a history of smoking. Among these 12 patients, 9 (75%) completed the eight-week outpatient-based PR program. Three patients could not complete the PR program: two were unwilling and one died from complications of lung cancer. This study showed a 75% completion rate of an eight-week outpatient-based PR program for advanced lung cancer patients undergoing cytotoxic chemotherapy, which supports its feasibility. © 2018 The Authors.

Little is known about the physical symptoms and psychosocial burden of patients at the time of diagnosis of an incurable situation, although cancer treatment guidelines demand early assessment and integration of palliative care concepts, beginning from the diagnosis of incurability. Therefore, we initiated a prospective longitudinal multicenter cohort study assessing the symptoms and needs of patients suffering from incurable cancer (various entities), from the time of diagnosing incurability (i.e., before palliative anticancer treatment was initiated) and in 3-monthly intervals thereafter, by using validated self-reporting tools. Here, we focus on patients with head and neck cancer and present preliminary results on symptoms and need prevalences, on clinical implications, and on the feasibility of a methodologically complex assessment procedure in a particularly vulnerable study population. 22 patients completed the first visit. The Eastern Cooperative Oncology Group (ECOG) performance scores and most physical symptoms and psychosocial items varied between the extremes, from a virtually uncompromised condition to extremely perceived symptoms and needs. If intense face-to-face study support was provided, the study concept proved to be feasible, despite the complexity of assessment, problems in interdisciplinary and patient communication, comorbidities, and early death from complications. The striking variability in the perceived symptom and need intensities requires a highly individualized approach. For clinical purposes, a less complex screening procedure would be desirable, in order to enable a routine, early and comprehensive support, including palliative care services. © 2016 S.

To develop and field-test a physical performance measure (MPS-PPM) for individuals with Mucopolysaccharidosis I (MPS I), a rare genetic disorder. Motor performance and endurance items were developed based on literature review, clinician feedback, feasibility, and equipment and training needs. A standardized testing protocol and scoring rules were created. The MPS-PPM includes: Arm Function (7 items), Leg Function (5 items), and Endurance (2 items). Pilot data were collected for 10 subjects (ages 5-29 years). We calculated Spearman's rho correlations between age, severity and summary z-scores on the MPS-PPM. Subjects had variable presentations, as correlations among the three sub-test scores were not significant. Increasing age was related to greater severity in physical performance (r = 0.72, p<0.05) and lower scores on the Leg Function (r = -0.67, p<0.05) and Endurance (r = -0.65, p<0.05) sub-tests. The MPS-PPM was sensitive to detecting physical performance deficits, as six subjects could not complete the full battery of Arm Function items and eight subjects were unable to complete all Leg Function items. Subjects walked more slowly and expended more energy than typically developing peers. Individuals with MPS I have difficulty with arm and leg function and reduced endurance. The MPS-PPM is a clinically feasible measure that detects limitations in physical performance and may have potential to quantify changes in function following intervention.

To investigate the feasibility and effects of a physical exercise programme on functioning and health-related quality of life in adults with myotonic dystrophy type 1. A randomized controlled trial. Thirty-five adults with myotonic dystrophy type 1. After stratification for level of functioning, study participants were assigned by lot to either a training group or a control group. Training-group participants attended a 60-minute comprehensive group-training programme, Friskis&Svettis® Open Doors, twice a week for 14 weeks. The six-minute walk test was the primary outcome measure and the timed-stands test, the timed up-and-go test, the Epworth sleepiness scale and the Short Form-36 health survey were secondary outcome measures. Intention-to-treat analyses revealed no significant differences in any outcome measures, except for an increased between-group difference after intervention in the Short Form-36 mental health subscale and a decrease in the vitality subscale for the control group. The programme was well tolerated and many training-group participants perceived subjective changes for the better. No negative effects were reported. The Friskis&Svettis® Open Doors programme was feasible for adults with myotonic dystrophy type 1 who had been screened for cardiac involvement, had distal or mild-to-moderate proximal muscle impairment, and no severe cognitive impairments. No beneficial or detrimental effects were evident.

Cancer survivors remain at increased risk for secondary malignancies, comorbidities, and all-cause mortality. Lifestyle behaviors, such as diet and physical activity, are strongly linked to a decreased risk of chronic disease and improved health outcomes, yet a paucity of research has been conducted in this vulnerable population. Adult cancer survivors were recruited to participate in Growing Hope, an experimental single-group study designed to assess the feasibility and efficacy of a theory-driven and evidence-based intervention. For 4 months, 22 participants received group and individual education and had access to harvesting fresh produce at an urban garden. Data on program satisfaction, compliance, diet, and physical activity were collected via surveys; anthropometrics, blood values, and skin carotenoids were objectively measured. The intervention resulted in significant improvements in consumption of fruits and vegetables (P = .003), decreased consumption of red and processed meats (P = .030) and sugar-sweetened beverages (P = .020). Levels of skin carotenoids, fasting blood glucose, and non-high density lipoprotein cholesterol were also significantly improved (P = .011, P = .043, and P = .05, respectively). The results of this study support the feasibility and efficacy of a multifaceted, garden-based intervention for cancer survivors. In addition, these preliminary results demonstrate a positive impact aligning with the current lifestyle recommendations for cancer survivorship. Larger randomized controlled trials are warranted to define impact on sustained health outcomes.

Adults with mental illness may have difficulties with data collection methods such as questionnaires and accelerometry. To assess the utility of questionnaires and accelerometry for assessing physical activity (PA) and sedentary behaviour (SB) in non-institutionalised adults with mental illness. Participants were recruited from outpatient clinics and community organisations. Participants completed PA and SB questionnaires, wore accelerometers for 7 d, and rated the ease/difficulty of completing study components. Recruitment numbers, adherence, and ease/difficulty ratings were examined. Ease/difficulty ratings were compared between study components, and between participants by distress level. One hundred forty-two participants completed the questionnaires; they found it easier to report PA than reclining time (p = 0.017), and reclining time than sitting time (p < 0.001). Participants with high distress found it more difficult to report sitting time and PA than participants with low distress (p < 0.017). Ninety-nine participants (70%) completed the accelerometry; the majority (88%) met the minimum wear-time criteria. They found it easier to wear the monitor during the day than while sleeping (p < 0.001), and easier to complete accelerometry than questionnaires (p < 0.001). Accelerometry was more feasible for assessing SB than questionnaires. Questionnaires were feasible for assessing PA, but less acceptable for people experiencing high distress.

Background Cancer survivors remain at increased risk for secondary malignancies, comorbidities, and all-cause mortality. Lifestyle behaviors, such as diet and physical activity, are strongly linked to a decreased risk of chronic disease and improved health outcomes, yet a paucity of research has been conducted in this vulnerable population. Methods Adult cancer survivors were recruited to participate in Growing Hope, an experimental single-group study designed to assess the feasibility and efficacy of a theory-driven and evidence-based intervention. For 4 months, 22 participants received group and individual education and had access to harvesting fresh produce at an urban garden. Data on program satisfaction, compliance, diet, and physical activity were collected via surveys; anthropometrics, blood values, and skin carotenoids were objectively measured. Results The intervention resulted in significant improvements in consumption of fruits and vegetables (P = .003), decreased consumption of red and processed meats (P = .030) and sugar-sweetened beverages (P = .020). Levels of skin carotenoids, fasting blood glucose, and non–high density lipoprotein cholesterol were also significantly improved (P = .011, P = .043, and P = .05, respectively). Conclusions The results of this study support the feasibility and efficacy of a multifaceted, garden-based intervention for cancer survivors. In addition, these preliminary results demonstrate a positive impact aligning with the current lifestyle recommendations for cancer survivorship. Larger randomized controlled trials are warranted to define impact on sustained health outcomes. PMID:27556671

The purpose of this pilot study was to test the feasibility of delivering the mobile mindfulness-based stress reduction for breast cancer (mMBSR(BC)) program using an iPad and to evaluate its impact on symptom improvement. A single group, pre-posttest design was implemented among female stages 0-III breast cancer survivors (BCS) who completed treatment. Data were collected at baseline and week 6 on measures of psychological and physical symptoms and quality of life. The mMBSR(BC) program is a standardized, stress-reducing intervention that combines sitting and walking meditation, body scan, and yoga and is designed to deliver weekly 2-hour sessions for 6 weeks using an iPad. The mean age of the 15 enrolled BCS was 57 years; one participant was non-Hispanic black, and 14 were non-Hispanic white. Of the 13 who completed the study, there were significant improvements from baseline to 6 weeks post-mMBSR(BC) in psychological and physical symptoms of depression, state anxiety, stress, fear of recurrence, sleep quality, fatigue, and quality of life (P's < .05). Effect sizes for improvements of multiple symptoms ranged from medium to large. These results provide preliminary support that the mMBSR(BC) program may be feasible and acceptable, showing a clinical impact on decreasing psychological and physical symptoms. This mobile-based program offers a delivery of a standardized MBSR(BC) intervention to BCS that is convenient for their own schedule while decreasing symptom burden in the survivorship phase after treatment for breast cancer.

To determine feasibility and preliminary effects of an occupational therapy treatment to improve upper extremity (UE) function in patients with early systemic sclerosis (SSc) who have UE contractures. A one-arm pilot clinical rehabilitation trial was conducted at a university health system. Participants with SSc and ≥ 1 UE contracture (n = 21) participated in a total of 8 weekly in-person occupational therapy sessions. The therapy consisted of thermal modalities, tissue mobilization, and UE mobility. Between sessions, participants were instructed to complete UE home exercises. Feasibility was measured by percent enrollment and session attendance and duration. The primary outcome measure was the QuickDASH, secondary and exploratory outcomes included PROMIS physical function, objective UE measures, and skin thickening. Linear mixed models were performed to determine treatment effects on primary and secondary outcomes. Fifty percent (24/48) of potentially eligible participants were interested. Of those, 88% (21/24) enrolled; and nineteen out of 21 (91%) completed all sessions. The mean (SD) age was 47.9 years (± 16.1); 100% had diffuse SSc, and mean disease duration was 3.1 years. At 8 weeks, participants reported statistically significant improvement on QuickDASH and PROMIS physical function measures (p =.0012 and p = .004). Forty-seven and 53% percent of the sample achieved improvements that exceeded minimally important differences. In-person treatment sessions were feasible for individuals with SSc and demonstrated statistically significant and clinically meaningful improvements on UE and physical function. Future studies need to examine effects against a control condition and examine durability of treatment effects. This article is protected by copyright. All rights reserved.

Evidence related to the effects of tobacco exposure in pregnancy and on infant and child health have focused on women's smoking cessation. Less often addressed is men's smoking, which when continued in fatherhood, reduces the chances of female partners' cessation and can negatively impact children's health as well as men's health. Dads in Gear (DIG) is an innovative program designed specifically for new fathers who want to reduce and quit smoking that includes three components: smoking cessation, fathering, and physical activity. The over-arching purpose of this study is to evaluate the feasibility of the DIG program and provide estimates of program efficacy. The purpose of this article is to describe the rationale and protocol for evaluating the DIG program's feasibility, acceptability and potential effectiveness. Using a prospective, non-comparative design, the DIG program will be implemented and evaluated in six communities. The program will be offered by trained facilitators to fathers who currently smoke and want to quit. The RE-AIM framework will guide the evaluation. Open-ended questions in participant surveys, and semi-structured interviews and weekly telephone de-briefs with facilitators will provide data for a process evaluation. Estimates of effectiveness include smoking behavior, fathering and physical activity measures at baseline, end of program, and 3-month follow up. The DIG program could support positive changes with respect to smoking cessation, physical activity and overall health for men. These effects could also promote family health. The program might also provide an effective model for engaging men in other health behavior change. Copyright © 2017 The Authors. Published by Elsevier Inc. All rights reserved.

Background Cancer survivors suffer from long-term adverse effects that reduce health-related quality of life (QOL) and physical functioning, creating an urgent need to develop effective, durable, and disseminable interventions. Harvest for Health, a home-based vegetable gardening intervention, holds promise for these domains. Methods This report describes the methods and recruitment experiences from two randomized controlled feasibility trials that employ a waitlist-controlled design. Delivered in partnership with Cooperative Extension Master Gardeners, this intervention provides one-on-one mentorship of cancer survivors in planning and maintaining three seasonal vegetable gardens over 12 months. The primary aim is to determine intervention feasibility and acceptability; secondary aims are to explore effects on objective and subjective measures of diet, physical activity and function, and QOL and examine participant factors associated with potential effects. One trial is conducted exclusively among 82 female breast cancer survivors residing in the Birmingham, AL metropolitan area (BBCS); another broadly throughout Alabama among 46 older cancer survivors aged ≥60 (ASCS). Results Response rates were 32.6% (BBCS) and 52.3% (ASCS). Both trials exceeded 80% of their accrual target. Leading reasons for ineligibility were removal of >10 lymph nodes (lymphedema risk factor), lack of physician approval, and unwillingness to be randomized to the waitlist. Conclusion To date, recruitment and implementation of Harvest for Health appears feasible. Discussion Although both studies encountered recruitment challenges, lessons learned can inform future larger-scale studies. Vegetable gardening interventions are of interest to cancer survivors and may provide opportunities to gain life skills leading to improvements in overall health and QOL. PMID:27565830

Studies support the use of exercise prescriptions in adults, but few studies have evaluated their use in children. One common barrier to effective physical activity counseling is lack of resources. Outdoors Rx is a collaboration between the Appalachian Mountain Club and the Massachusetts General Hospital for Children that pairs exercise prescriptions with guided outdoor programs to increase physical activity among children. This article describes the design and implementation of Outdoors Rx at 2 community health centers serving ethnically diverse, low-income, urban families, as well as evaluates feedback from participating pediatricians regarding the utility of the program, barriers to success, and suggestions for improvement. Our results illustrate the feasibility of implementing a pediatric physical activity prescription program in community health centers serving traditionally underserved populations. Our data suggest that physical activity prescription programs are well received by both pediatricians and families and are a useful tool for facilitating physical activity counseling.

How I do it: feasibility of a new ultrasound probe fixator to facilitate high quality stress echocardiography.

PubMed

Stress echocardiography (SE) has recently regained momentum as an important diagnostic tool for the assessment of both ischemic and non-ischemic heart disease. Performing SE during physical exercise is challenging due to a suboptimal patient position and vigorous movements of the patient's chest. This hampers a stable ultrasound position and reduces the diagnostic performance of SE. A stable ultrasound probe position would facilitate producing high quality images during continuous measurements. With Probefix (Usono, Eindhoven, The Netherlands), a newly developed tool to fixate the ultrasound probe to the patient's chest, stabilization of the probe during physical exercise is possible. The technique of SE with the Probefix and its' feasibility are evaluated in a small pilot study. Probefix fixates the ultrasound probe to the patient's chest, using two chest straps and a fixation device. The ultrasound probe position and angle may be altered with a relative high degree of freedom. We tested the Probefix for continuous echocardiographic imaging in 12 study subjects during supine and upright ergometer stress tests. One patient was unable to perform exercise and in two study subjects good quality images were not achieved. In the other patients (82%) a stable probe position was obtained, with subsequent good quality echocardiographic images during SE. We have demonstrated the feasibility of the Probefix support during ergometer tests in supine and upright positions and conclude that this external fixator may facilitate continuous monitoring of cardiac function in a group of patients.

In Scotland, older adults are a key target group for physical activity intervention due to the large proportion who are inactive. The health benefits of an active lifestyle are well established but more research is required on the most effective interventions to increase activity in older adults. The 'West End Walkers 65+' randomised controlled trial aims to examine the feasibility of delivering a pedometer-based walking intervention to adults aged 65 years through a primary care setting and to determine the efficacy of this pilot. The study rationale, protocol and recruitment process are discussed in this paper. The intervention consisted of a 12-week pedometer-based graduated walking programme and physical activity consultations. Participants were randomised into an immediate intervention group (immediate group) or a 12-week waiting list control group (delayed group) who then received the intervention. For the pilot element of this study, the primary outcome measure was pedometer step counts. Secondary outcome measures of sedentary time and physical activity (time spent lying/sitting, standing or walking; activPAL™ monitor), mood (Positive and Negative Affect Schedule), functional ability (Perceived Motor-Efficacy Scale for Older Adults), quality of life (Short-Form (36) Health Survey version 2) and loneliness (UCLA Loneliness Scale) were assessed. Focus groups with participants and semi-structured interviews with the research team captured their experiences of the intervention. The feasibility component of this trial examined recruitment via primary care and retention of participants, appropriateness of the intervention for older adults and the delivery of the intervention by a practice nurse. West End Walkers 65+ will determine the feasibility and pilot the efficacy of delivering a pedometer-based walking intervention through primary care to Scottish adults aged 65 years. The study will also examine the effect of the intervention on the well-being of participants and gain an insight into both participant and research team member experiences of the intervention.

Patients with colorectal cancer report ongoing physical and psychological impairments and a high proportion of these patients are overweight, insufficiently active and high-risk drinkers, putting them at risk of poor recovery and risk of recurrence and comorbidities. A challenge is implementing sustainable and effective rehabilitation as part of routine care for this group. A two-arm pilot randomised controlled trial (RCT) with embedded feasibility study undertaken as a phased programme of work. The intervention involves an existing cardiac rehabilitation programme for cardiac patients accepting colorectal cancer patient referrals. The intervention consists of supervised exercise sessions run by a cardiac physiotherapist and information sessions. Phase 1 will involve one research site enrolling 12 patients to assess intervention and study design processes. Semistructured interviews with patients with colorectal cancer and cardiac patients and clinicians will be used to gather data on acceptability of the intervention and study procedures. Phase 2 will involve three sites enrolling 66 patients with colorectal cancer randomised to control or intervention groups. Outcome measures will be taken preintervention and postintervention, for phases 1 and 2. The primary outcome is accelerometer measured physical activity; secondary outcomes are self-report physical activity, quality of life, anxiety, depression, symptoms including fatigue. The following variables will also be examined to determine if these factors influence adherence and outcomes: self-efficacy, risk perception and treatments. Full ethical approval was granted by NRES Committees-North of Scotland (13/NS/0004; IRAS project ID: 121757) on 22 February 2013. The proposed work is novel in that it aims to test the feasibility and acceptability of using an evidence-based and theory driven existing cardiac rehabilitation service with patients with colorectal cancer. Should this model of rehabilitation prove to be clinically and cost effective we aim to conduct a randomised controlled trial of this intervention to measure effectiveness.

Verheijden Klompstra, Leonie; Jaarsma, Tiny; Strömberg, Anna

2013-01-01

Background: Physical activity can improve exercise capacity, quality of life and reduce mortality and hospitalization in patients with heart failure (HF). Adherence to exercise recommendations in patients with HF is low. The use of exercise games (exergames) might be a way to encourage patients with HF to exercise especially those who may be reluctant to more traditional forms of exercise. No studies have been conducted on patients with HF and exergames. Aim: This scoping review focuses on the feasibility and influence of exergames on physical activity in older adults, aiming to target certain characteristics that are important for patients with HF to become more physically active. Methods: A literature search was undertaken in August 2012 in the databases PsychInfo, PUBMED, Scopus, Web of Science and CINAHL. Included studies evaluated the influence of exergaming on physical activity in older adults. Articles were excluded if they focused on rehabilitation of specific limbs, improving specific tasks or describing no intervention. Fifty articles were found, 11 were included in the analysis. Results: Exergaming was described as safe and feasible, and resulted in more energy expenditure compared to rest. Participants experienced improved balance and reported improved cognitive function after exergaming. Participants enjoyed playing the exergames, their depressive symptoms decreased, and they reported improved quality of life and empowerment. Exergames made them feel more connected with their family members, especially their grandchildren. Conclusion: Although this research field is small and under development, exergaming might be promising in order to enhance physical activity in patients with HF. However, further testing is needed.

Objective Lifestyle interventions that promote physical activity and healthy dietary habits may reduce binge eating symptoms and be more feasible and sustainable among ethnic minority women, who are less likely to seek clinical treatment for eating disorders. The purpose of this study was to investigate (1) whether participating in a lifestyle intervention is a feasible way to decrease binge eating symptoms (BES) and (2) whether changes in BES differed by intervention (physical activity vs. dietary habits) and binge eating status at baseline (binger eater vs. non-binge eater) in African American and Hispanic women. Method Health Is Power (HIP) was a longitudinal randomized controlled trial to promote physical activity and improve dietary habits. Women (N=180) who completed anthropometric measures and questionnaires assessing fruit and vegetable and dietary fat intake, BES and demographics at baseline and post-intervention six months later were included in the current study. Results Over one-fourth (27.8%) of participants were categorized as binge-eaters. Repeated measures ANCOVA analyses ANOVA demonstrated significant two- and three-way interactions. Decreases in BES over time were greater in binge eaters than in non-binge eaters (F(1,164)=33.253, p<.001), and women classified as binge eaters who participated in the physical activity intervention reported greater decreases in BES than non-binge eaters in the dietary habits intervention (F(1,157)=5.170, p=.024). Discussion Findings suggest behavioral interventions to increase physical activity may lead to reductions in BES among ethnic minority women and ultimately reduce the prevalence of binge eating disorder and health disparities in this population.

2015-01-01

People with severe speech and physical impairments may benefit from mindfulness meditation training because it has the potential to enhance their ability to cope with anxiety, depression and pain and improve their attentional capacity to use brain-computer interface systems. Seven adults with severe speech and physical impairments (SSPI) - defined as speech that is understood less than 25% of the time and/or severely reduced hand function for writing/typing - participated in this exploratory, uncontrolled intervention study. The objectives were to describe the development and implementation of a six-week mindfulness meditation intervention and to identify feasible outcome measures in this population. The weekly intervention was delivered by an instructor in the participant's home, and participants were encouraged to practise daily using audio recordings. The objective adherence to home practice was 10.2 minutes per day. Exploratory outcome measures were an n-back working memory task, the Attention Process Training-II Attention Questionnaire, the Pittsburgh Sleep Quality Index, the Perceived Stress Scale, the Positive and Negative Affect Schedule, and a qualitative feedback survey. There were no statistically significant pre-post results in this small sample, yet administration of the measures proved feasible, and qualitative reports were overall positive. Obstacles to teaching mindfulness meditation to persons with SSPI are reported, and solutions are proposed.

There are few studies of mobile-Health (mHealth) device application with schizophrenic patients. We aimed to quantitatively assess patient's activity and the relationship between their physical activity and the severity of their psychopathologies. Then we attempted to identify the patients who required intervention and evaluated the feasibility of using the mHealth device. A total of 61 of the 76 available hospitalized patients with chronic schizophrenia who participated in the activity programs were enrolled. They wore a mHealth device for a week to assess their activity (steps/day). The Positive and Negative Syndrome Scale (PANSS) was completed by the subjects. As a result, the positive subscale of the PANSS and the positive and negative factors of the PANSS 5-factor structure showed a predictive value for low levels of physical activity. The group of subjects with a high total PANSS score had a significantly lower level of physical activity than the other groups. In conclusion, physical activity showed a significant association with positive symptoms as well as negative symptoms. The mHealth device showed relatively good feasibility for schizophrenic patients. We should pay more attention to the activity of patients with high PANSS scores.

Yoshida, Beni, E-mail: rouge@mit.edu

2011-10-15

Recently, it has become apparent that the thermal stability of topologically ordered systems at finite temperature, as discussed in condensed matter physics, can be studied by addressing the feasibility of self-correcting quantum memory, as discussed in quantum information science. Here, with this correspondence in mind, we propose a model of quantum codes that may cover a large class of physically realizable quantum memory. The model is supported by a certain class of gapped spin Hamiltonians, called stabilizer Hamiltonians, with translation symmetries and a small number of ground states that does not grow with the system size. We show that themore » model does not work as self-correcting quantum memory due to a certain topological constraint on geometric shapes of its logical operators. This quantum coding theoretical result implies that systems covered or approximated by the model cannot have thermally stable topological order, meaning that systems cannot be stable against both thermal fluctuations and local perturbations simultaneously in two and three spatial dimensions. - Highlights: > We define a class of physically realizable quantum codes. > We determine their coding and physical properties completely. > We establish the connection between topological order and self-correcting memory. > We find they do not work as self-correcting quantum memory. > We find they do not have thermally stable topological order.« less

Background Structured exercise programs for frail institutionalized seniors have shown improvement in physical, functional, and psychological health of this population. However, the ‘feasibility’ of implementation of such programs in real settings is seldom discussed. The purpose of this systematic review was to gauge feasibility of exercise and falls prevention programs from the perspective of long-term care homes in Ontario, given the recent changes in funding for publically funded physiotherapy services. Method Six electronic databases were searched by two independent researchers for randomized controlled trials that targeted long-term care residents and included exercise as an independent component of the intervention. Results A total of 39 studies were included in this review. A majority of these interventions were led by physiotherapist(s), carried out three times per week for 30–45 minutes per session. However, a few group-based interventions that were led by long-term care staff, volunteers, or trained non-exercise specialists were identified that also required minimal equipment. Conclusion This systematic review has identified ‘feasible’ physical activity and falls prevention programs that required minimal investment in staff and equipment, and demonstrated positive outcomes. Implementation of such programs represents cost-effective means of providing long-term care residents with meaningful gains in physical, psychological, and social health. PMID:26180563

Hadjidakis, Cynthia; Anselmino, Mauro; Arnaldi, R.

By extracting the beam with a bent crystal or by using an internal gas target, the multi-TeV proton and lead LHC beams allow one to perform the most energetic fixed-target experiments (AFTER@LHC) and to study p+p and p+A collisions at \\sqrt{s_NN}=115 GeV and Pb+p and Pb+A collisions at \\sqrt{s_NN}=72 GeV. Such studies would address open questions in the domain of the nucleon and nucleus partonic structure at high-x, quark-gluon plasma and, by using longitudinally or transversally polarised targets, spin physics.

Introduction This study assessed the feasibility and efficacy of a novel resistance training device used within an intradialytic progressive resistance training (PRT) intervention. Methods Non-randomized, within-subjects crossover design with outcomes assessed at baseline (week 0), postcontrol (week 13) and post-PRT intervention (week 26). Twenty-two hemodialysis patients (59% men, 71 ± 11 years) performed PRT three sessions per week for 12 weeks. The resistance training device was developed to enable the performance of 2 upper body and 3 lower body exercises, unilaterally and bilaterally, both before and during dialysis, with loads of 2.5 to 59 kg. Feasibility outcomes included adverse events, adherence and training load progression. Changes in upper and lower body muscular strength, six-minute walk, aspects of health-related quality of life (HRQoL) and depression were evaluated. Findings The PRT intervention was delivered without serious adverse events, resulted in 71.2% ± 23.3% adherence and significant adaptation of all training loads from pre to mid to post training (83.8%-185.6%, all P < 0.05). Lower body strength (P < 0.001) and HRQoL subscales (Role-Physical, Social Functioning, Role-Emotional) significantly increased (all P < 0.01) and a trend toward reduced depression was noted (P = 0.06). No significant changes were noted in other outcomes. Discussion PRT using the novel resistance training device was feasible and improved measures of physical and psychological health. This device can be utilized in most dialysis centers. Future studies are required to evaluate dose-response effects of PRT prescriptions in subpopulations, and the translation of PRT to standard dialysis practice. © 2016 International Society for Hemodialysis.

We designed and implemented the Brigham and Women's Wellness Initiative (B-Well), a single-arm study to examine the feasibility of a workplace program that used individual and team-based financial incentives to increase physical activity among sedentary hospital employees. We enrolled sedentary, non-clinician employees of a tertiary medical center who self-reported low physical activity. Eligible participants formed or joined teams of three members and wore Fitbit Flex activity monitors for two pre-intervention weeks followed by 24 weeks during which they could earn monetary rewards. Participants were rewarded for increasing their moderate-to-vigorous physical activity (MVPA) by 10% from the previous week or for meeting the Centers for Disease Control and Prevention (CDC) physical activity guidelines (150 min of MVPA per week). Our primary outcome was the proportion of participants meeting weekly MVPA goals and CDC physical activity guidelines. Secondary outcomes included Fitbit-wear adherence and factors associated with meeting CDC guidelines more consistently. B-Well included 292 hospital employees. Participants had a mean age of 38 years (SD 11), 83% were female, 38% were obese, and 62% were non-Hispanic White. Sixty-three percent of participants wore the Fitbit ≥4 days per week for ≥20 weeks. Two-thirds were satisfied with the B-Well program, with 79% indicating that they would participate again. Eighty-six percent met either their personal weekly goal or CDC physical activity guidelines for at least 6 out of 24 weeks, and 52% met their goals or CDC physical activity guidelines for at least 12 weeks. African Americans, non-obese subjects, and those with lower impulsivity scores reached CDC guidelines more consistently. Our data suggest that a financial incentives-based workplace wellness program can increase MVPA among sedentary employees. These results should be reproduced in a randomized controlled trial.

The purpose of this study was to determine the feasibility and acceptability of utilizing a smartphone based application to monitor compliance in patients with cardiac disease around discharge. For 60 days after discharge, patients' medication compliance, physical activity, follow-up care, symptoms, and reading of education material were monitored daily with the application. 16 patients were enrolled in the study (12 males, 4 females, age 55 ± 18 years) during their hospital stay. Five participants were rehospitalized during the study and did not use the application once discharged. Seven participants completed 1–30 days and four patients completed >31 days. For those 11 patients, medication reminders were utilized 37% (1–30-day group) and 53% (>31-day group) of the time, education material was read 44% (1–30) and 53% (>31) of the time, and physical activity was reported 25% (1–30) and 42% (>31) of the time. Findings demonstrated that patients with stable health utilized the application, even if only minimally. Patients with decreased breath sounds by physical exam and who reported their health as fair to poor on the day of discharge were less likely to utilize the application. Acceptability of the application to report health status varied among the stable patients. PMID:25574165

Smoking is the leading preventable cause of chronic disease and premature morbidity. People with physical disabilities experience elevated smoking prevalence when compared with their non-disabled peers. The physical therapy profession is dedicated to meeting needs of people with physical disabilities, yet most physical therapists (PT) do not typically provide tobacco cessation interventions. Similar deficits exist among other health professions, creating a demand for improved services to address smoking-related health burdens. Within other health professions, insufficient tobacco cessation counseling (TCC) education has been linked to a lack of interventions and may account for similar deficits in physical therapy practice. Goals were to assess feasibility, implementation, and results of a tailored TCC educational program for entry-level physical therapist (PT) students. Two cohorts of entry-level physical therapist (PT) students (n = 12 and n = 17). Educational objectives were established based on prior review of the literature, a survey of national PT education programs, and clinical guidelines for TCC established by the United States Public Health Service (USPHS). Based on these objectives, the team designed a 3-hour workshop involving didactic content and problem-based skills practice. A pre- and post-test survey was used to measure 6 dimensions: knowledge, perceived barriers, perceived facilitators, self-efficacy, outcome expectations, and self-rated skill in TCC. Within each cohort, changes in score were compared using a paired t test. The ability to apply clinical guidelines for TCC was assessed using case scenarios and structured observation. These outcomes were selected based on the Theory of Reasoned Action, which states that future behavior is determined by intention to act. Intention to act is a product of knowledge, a positive balance between perceived barriers and facilitators, strong self-efficacy, favorable outcome expectations, and necessary skills. Student satisfaction with training was assessed through anonymous written feedback. Feasibility was based on cost analysis, including material resources, as well as faculty time and effort. Following participation, both cohorts improved in knowledge, perceived facilitators, outcome expectations, and self-rated skill. Cohort 2 also showed an increase in self-efficacy ( P < .01). Structured observation revealed competencies in application of clinical guidelines for case-based scenarios. Mean student satisfaction ratings for the educational experience were 5/5, and cost-estimate for delivery of the 3-hour educational intervention was approximately $32 per student. This research study demonstrated feasibility and impact of an evidence-based curricular model designed to increase likelihood of TCC by future PTs by enhancing factors known to promote TCC behaviors. The program was well-received by students, and objectives were achieved through efficient use of faculty time and resources. Subsequent research should examine the effects of training on the provision of TCC within clinical settings, as well as the impact of TCC on smoking quit rates for patients who have received this intervention as a component of their physical therapy plan of care.

To investigate the feasibility of using video-games in a group setting and to compare the effectiveness of video-games as a group intervention to a traditional group intervention for improving physical activity in individuals with chronic stroke. A single-blind randomized controlled trial with evaluations pre and post a 3-month intervention, and at 3-month follow-up. Compliance (session attendance), satisfaction and adverse effects were feasibility measures. Grip strength and gait speed were measures of physical activity. Hip accelerometers quantified steps/day and the Action Research Arm Test assessed the functional ability of the upper extremity. Forty-seven community-dwelling individuals with chronic stroke (29-78 years) were randomly allocated to receive video-game (N=24) or traditional therapy (N=23) in a group setting. There was high treatment compliance for both interventions (video-games-78%, traditional therapy-66%), but satisfaction was rated higher for the video-game (93%) than the traditional therapy (71%) (χ(2)=4.98, P=0.026). Adverse effects were not reported in either group. Significant improvements were demonstrated in both groups for gait speed (F=3.9, P=0.02), grip strength of the weaker (F=6.67, P=0.002) and stronger hands (F=7.5, P=0.001). Daily steps and functional ability of the weaker hand did not increase in either group. Using video-games in a small group setting is feasible, safe and satisfying. Video-games improve indicators of physical activity of individuals with chronic stroke. © The Author(s) 2015.

There is as yet no evidence on the feasibility of implementing recommendations from the National Institute of Health and Care Excellence (NICE) osteoarthritis (OA) guidelines in primary care, or of the effect these recommendations have on the condition. The primary aim of this study is to determine the clinical and cost effectiveness of a model OA consultation (MOAC), implementing the core recommendations from the NICE OA guidelines in primary care. Secondary aims are to investigate the impact, feasibility and acceptability of the MOAC intervention; to develop and evaluate a training package for management of OA by general practitioners (GPs) and practice nurses; test the feasibility of deriving 'quality markers' of OA management using a new consultation template and medical record review; and describe the uptake of core NICE OA recommendations in participants aged 45 years and over with joint pain. A mixed methods study with a nested cluster randomised controlled trial. This study was developed according to a defined theoretical framework (the Whole System Informing Self-management Engagement). An overarching model (the Normalisation Process Theory) will be employed to undertake a comprehensive 'whole-system' evaluation of the processes and outcomes of implementing the MOAC intervention. The primary outcome is general physical health (Short Form-12 Physical component score [PCS]) (Ware 1996). The impact, acceptability and feasibility of the MOAC intervention at practice level will be assessed by comparing intervention and control practices using a Quality Indicators template and medical record review. Impact and acceptability of the intervention for patients will be assessed via self-completed outcome measures and semi-structured interviews. The impact, acceptability and feasibility of the MOAC intervention and training for GPs and practice nurses will be evaluated using a variety of methods including questionnaires, semi-structured interviews, and observations. The main output from the study will be to determine whether the MOAC intervention is clinically and cost effective. Additional outputs will be the development of the MOAC for patients consulting with joint pain in primary care, training and educational materials, and resources for patients and professionals regarding supported self-management and uptake of NICE guidance.

To the best of our knowledge, there has been no study on yoga that includes both persons with multiple sclerosis (MS) and their family members. Because yoga has therapeutic effects in both persons with MS and healthy persons, we hypothesized that it would be an effective method to improve not only the physical and psychosocial status but also the time persons with MS and their family members spend together. To examine the feasibility of a 6-month (long-term) yoga program to improve the physical and psychosocial status of persons with MS and their family members. Uncontrolled clinical trial. The protocol was developed at the Department of Neurology, Faculty of Medicine, and School of Physical Therapy and Rehabilitation, Dokuz Eylül University, Izmir, Turkey. Persons with MS and healthy family members. Walking, balance, fatigue, health-related quality of life, depression, pain, and kinesiophobia. Yoga training was given once a week (at least 1h) for 6 months. The same assessors who assessed at baseline also performed the same assessments immediately after the end of the training (i.e., after 6 months). In total, 44 participants (27 persons with MS and 17 healthy family members) participated in the study. Twelve persons with MS and three healthy family members completed the 6-month yoga intervention. The completion rate for persons with MS and healthy subjects was 44.4% and 17.6%, respectively. In persons with MS, the mental dimension of health-related quality of life, walking speed, fatigue, and depression levels significantly improved after the yoga program (p < .05). However, there was no significant change in the self-reported walking impact, balance, pain, physical dimension of health-related quality of life, and kinesiophobia levels in the persons with MS (p > .05). This study suggests that a 6-month yoga program can improve the mental dimension of health-related quality of life, walking speed, fatigue, and depression in the persons with MS. However, the 6-month yoga program does not appear to be a feasible method to increase the time that persons with MS spend together with their family members. Copyright © 2018 Elsevier Inc.

Chronic illness places high demands on patients. Interventions supporting self-management and providing personalized feedback might help patients to gain new perspectives and enhance use of constructive self-management strategies. We developed three comparable web-based CBT-grounded interventions including e-diaries and feedback delivered through PDAs/smartphones. The feasibility and efficacy of these interventions have been investigated for patients with irritable bowel syndrome (in an RCT), chronic widespread pain (RCT) and type 2 diabetes (feasibility study). This is a descriptive study that summarizes the content, feasibility and efficacy of the interventions and discusses issues relevant for implementing this type of web-based therapeutic interventions in clinical practice. The web-based interventions appear feasible, acceptable and supportive. In a short and midterm time frame, the interventions promote self-management. Booster sessions may be needed for prolonged effects. Given the physical and mental symptoms of the patients under study and the nature of the intervention, providers who deliver the feedback need a health care background and training in this specific way of counseling. The results of the three studies suggest that personalized web-based interventions are effective and have the potential to support self-management in daily healthcare. Studies concerning clinical significance and implementation are needed. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

This comprehensive review examined the effects of mindfulness-based interventions on the physical and emotional wellbeing of older adults, a rapidly growing segment of the general population. Search procedures yielded 15 treatment outcome studies meeting inclusion criteria. Support was found for the feasibility and acceptability of mindfulness-based interventions with older adults. Physical and emotional wellbeing outcome variables offered mixed support for the use of mindfulness-based interventions with older adults. Potential explanations of mixed findings may include methodological flaws, study limitations, and inconsistent modifications of protocols. These are discussed in detail and future avenues of research are discussed, emphasizing the need to incorporate geriatric populations into future mindfulness-based empirical research. PMID:27200109

Physical activity levels in bariatric patients have not been well documented, despite their importance in maintaining weight loss following surgery. This study investigated the feasibility of tracking physical activity using a smartphone app with minimal user interaction. Thus far, we have obtained good quality data from 255 patients at various points in their weight loss journey. Preliminary analyses indicate little change in physical activity levels following surgery with pre-surgery patients reaching an average of 16 minutes per day and post-surgery patients achieving a daily average of 21 minutes. Further analyses using machine-learning techniques will be conducted to determine whether physical activity is a critical factor in distinguishing between successful and unsuccessful weight loss outcomes and in the resolution of comorbid conditions in patients with similar clinical profiles.

Evidence that lifestyle factors are associated with better outcomes in colorectal cancer (CRC) survivors highlights the need for behaviour change interventions. This study examined feasibility and acceptability, and provided an indication of behavioural impact, of a telephone-based, multimodal health behaviour intervention for CRC survivors. Participants were recruited from five London hospitals. Patients (n = 29) who had recently completed treatment for CRC participated in a 12 week intervention. Behavioural goals were to increase physical activity (PA) and fruit and vegetable (F&V) intake, and reduce consumption of red/processed meat and alcohol. Self-report measures of PA and diet were completed in all patients, supplemented by objective measures in a sub-set. Uptake of the study when patients were approached by a researcher was high (72%), compared with 27% contacted by letter. Methods for identifying eligible patients were not optimal. Study completion rate was high (79%), and completers evaluated the intervention favourably. Significant improvements were observed in objectively-measured activity (+70 min/week; p = .004). Gains were seen in diet: +3 F&V portions a day (p < .001), -147 g of red meat a week (p = .013), -0.83 portions of processed meat a week (p = .002). Changes in serum vitamin levels were not statistically significant, but the small sample size provides limited power. Clinically meaningful improvement in quality of life (p < .001) was observed. An intervention combining print materials and telephone consultations was feasible and acceptable, and associated with improvements in PA, diet and quality of life. Copyright © 2014 The Authors.

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

Therapeutic hypothermia has become standard of care in newborns with moderate and severe neonatal encephalopathy; however, additional interventions are needed. In experimental models, breathing xenon gas during cooling offers long-term additive neuroprotection. This is the first xenon feasibility study in cooled infants. Xenon is expensive, requiring a closed-circuit delivery system. Cooled newborns with neonatal encephalopathy were eligible for this single-arm, dose-escalation study if clinically stable, under 18 hours of age and requiring less than 35% oxygen. Xenon duration increased stepwise from 3 to 18 hours in 14 subjects; 1 received 25% xenon and 13 received 50%. Respiratory, cardiovascular, neurologic (ie, amplitude-integrated EEG, seizures), and inflammatory (C-reactive protein) effects were examined. The effects of starting or stopping xenon rapidly or slowly were studied. Three matched control subjects per xenon treated subject were selected from our cooling database. Follow-up was at 18 months using mental developmental and physical developmental indexes of the Bayley Scales of Infant Development II. No adverse respiratory or cardiovascular effects, including post-extubation stridor, were seen. Xenon increased sedation and suppressed seizures and background electroencephalographic activity. Seizures sometimes occurred during rapid weaning of xenon but not during slow weaning. C-reactive protein levels were similar between groups. Hourly xenon consumption was 0.52 L. Three died, and 7 of 11 survivors had mental and physical developmental index scores ≥70 at follow-up. Breathing 50% xenon for up to 18 hours with 72 hours of cooling was feasible, with no adverse effects seen with 18 months' follow-up. Copyright © 2014 by the American Academy of Pediatrics.

Endometrial cancer survivors comprise a high-risk group for obesity-related comorbidities. Healthy eating and physical activity can lead to better health and well-being, but this population may experience difficulties adopting healthy lifestyle practices. Personalised behaviour change programmes that are feasible, acceptable and cost-effective are needed. The aim of this trial is to pilot a manualised programme about healthy eating and physical activity. This is a phase II, individually randomized, parallel, controlled, two-site, pilot clinical trial. Adult endometrial cancer survivors (n = 64) who have been diagnosed with endometrial cancer within the previous 3 years and are not on active treatment will be invited to participate. Participants will be assigned in a 1:1 ratio through minimisation to either an 8-week, group-based, behaviour-change programme with weekly 90-min sessions about healthy eating and physical activity or usual care. The intervention will focus on self-monitoring, goal setting and self-rewards. Follow-up assessments will be conducted at 8 and 24 weeks from the baseline assessment. Primary feasibility outcomes will include rates of recruitment, adherence, and retention. The study results will inform the development of a definitive randomised controlled trial to test if the programme can improve the health and quality of life of this population. It will also provide guidance on costing the intervention and the health care resource use in this population. ClinicalTrials.gov identifier: NCT02433080, 20 April 2015.

The creation of cold antihydrogen atoms by the controlled combination of positrons and antiprotons has opened up a new window on fundamental physics. More recently, techniques have been developed that allow some antihydrogen atoms to be created at low enough kinetic energies that they can be held inside magnetic minimum neutral atom traps. With confinement times of many minutes possible, it has become feasible to perform experiments to probe the properties of the antiatom for the first time. We review the experimental progress in this area, outline some of the motivation for studying basic aspects of antimatter physics and provide an outlook of where we might expect this field to go in the coming years.

In this study, a simple and delicate approach to realizing manipulation of multi-physics field simultaneously through combination of passive and active schemes is proposed. In the design, one physical field is manipulated with passive scheme while the other with active scheme. As a proof of this concept, a bifunctional device is designed and fabricated to behave as electric and thermal invisibility cloak simultaneously. It is found that the experimental results are consistent with the simulated ones well, confirming the feasibility of our method. Furthermore, the proposed method could also be extended to other multi-physics fields, which might lead to potential applications in thermal, electric, and acoustic areas.

The paper presents the results of physical modeling and experimental study of the frequency characteristics of the polyfrequency filter-compensating device (PFCD) based on a capacitor-coil. The amplitude- frequency and phase-frequency characteristics of the physical PFCD model were constructed and its equivalent parameters were identified. The feasibility of a PFCD in the form of a single technical device with high technical and economic characteristics was experimentally proven. In the paper, recommendations for practical applications of the capacitor-coil-based PFCD are made and the advantages of the device over known standard passive filter-compensating devices are evaluated.

Positive psychological constructs, such as optimism, are associated with greater participation in cardiac health behaviors and improved cardiac outcomes. Positive psychology interventions, which target psychological well-being, may represent a promising approach to improving health behaviors in high-risk cardiac patients. However, no study has assessed whether a positive psychology intervention can promote physical activity following an acute coronary syndrome. In this article we will describe the methods of a novel factorial design study to aid the development of a positive psychology-based intervention for acute coronary syndrome patients and aim to provide preliminary feasibility data on study implementation. The Positive Emotions after Acute Coronary Events III study is an optimization study (planned N = 128), subsumed within a larger multiphase optimization strategy iterative treatment development project. The goal of Positive Emotions after Acute Coronary Events III is to identify the ideal components of a positive psychology-based intervention to improve post-acute coronary syndrome physical activity. Using a 2 × 2 × 2 factorial design, Positive Emotions after Acute Coronary Events III aims to: (1) evaluate the relative merits of using positive psychology exercises alone or combined with motivational interviewing, (2) assess whether weekly or daily positive psychology exercise completion is optimal, and (3) determine the utility of booster sessions. The study's primary outcome measure is moderate-to-vigorous physical activity at 16 weeks, measured via accelerometer. Secondary outcome measures include psychological, functional, and adherence-related behavioral outcomes, along with metrics of feasibility and acceptability. For the primary study outcome, we will use a mixed-effects model with a random intercept (to account for repeated measures) to assess the main effects of each component (inclusion of motivational interviewing in the exercises, duration of the intervention, and inclusion of booster sessions) from a full factorial model controlling for baseline activity. Similar analyses will be performed on self-report measures and objectively-measured medication adherence over 16 weeks. We hypothesize that the combined positive psychology and motivational interviewing intervention, weekly exercises, and booster sessions will be associated with superior physical activity. Thus far, 78 participants have enrolled, with 72% of all possible exercises fully completed by participants. The Positive Emotions after Acute Coronary Events III study will help to determine the optimal content, intensity, and duration of a positive psychology intervention in post-acute coronary syndrome patients prior to testing in a randomized trial. This study is novel in its use of a factorial design within the multiphase optimization strategy framework to optimize a behavioral intervention and the use of a positive psychology intervention to promote physical activity in high-risk cardiac patients.

Physiotherapy for sleep disturbance in chronic low back pain: a feasibility randomised controlled trial

PubMed Central

2010-01-01

Background Sleep disturbance is becoming increasingly recognised as a clinically important symptom in people with chronic low back pain (CLBP, low back pain >12 weeks), associated with physical inactivity and depression. Current research and international clinical guidelines recommend people with CLBP assume a physically active role in their recovery to prevent chronicity, but the high prevalence of sleep disturbance in this population may be unknowingly limiting their ability to participate in exercise-based rehabilitation programmes and contributing to poor outcomes. There is currently no knowledge concerning the effectiveness of physiotherapy on sleep disturbance in people with chronic low back pain and no evidence of the feasibility of conducting randomized controlled trials that comprehensively evaluate sleep as an outcome measure in this population. Methods/Design This study will evaluate the feasibility of a randomised controlled trial (RCT), exploring the effects of three forms of physiotherapy (supervised general exercise programme, individualized walking programme and usual physiotherapy, which will serve as the control group) on sleep quality in people with chronic low back pain. A presenting sample of 60 consenting patients will be recruited in the physiotherapy department of Beaumont Hospital, Dublin, Ireland, and randomly allocated to one of the three groups in a concealed manner. The main outcomes will be sleep quality (self-report and objective measurement), and self-reported functional disability, pain, quality of life, fear avoidance, anxiety and depression, physical activity, and patient satisfaction. Outcome will be evaluated at baseline, 3 months and 6 months. Qualitative telephone interviews will be embedded in the research design to obtain feedback from a sample of participants' about their experiences of sleep monitoring, trial participation and interventions, and to inform the design of a fully powered future RCT. Planned analysis will explore trends in the data, effect sizes and clinically important effects (quantitative data), and thematic analysis (qualitative data). Discussion This study will evaluate the feasibility of a randomised controlled trial exploring the effects of three forms of physiotherapy (supervised general exercise programme, individualized walking programme and usual physiotherapy, which will serve as the control group) on sleep quality in people with chronic low back pain.

2009-02-01

To evaluate a newly developed cholecystectomy technique which combines classical dissection with currently available mini-instrumentation (3 and 5 mm) and removal of the gallbladder through a short gastrotomy. After a feasibility study, we set up a protocol for this procedure using instrumentation currently available on the market. The resected gallbladder was removed through a short gastrotomy on the anterior gastric wall, thereby minimizing abdominal wall trauma and permitting the patient to resume physical activity more quickly with no risk of trocar herniation. Cholecystectomy was performed by the described technique in 18 of 23 eligible patients between April 2008 and August 2008. There were seven males and 11 females with a mean age of 48 (range: 28-77); median BMI was 30 kg/m2 (range: 22-36). Eleven patients had a gallstone larger than 12 mm. There were no postoperative complications and recovery was rapid for all patients in our study. This procedure is technically feasible, safe and reproducible; results are good with minimal trauma to the abdominal wall. Normal physical activity can be rapidly resumed with no risk of incisional hernia.

Growing concern for falls in acute care settings could be addressed with objective evaluation of fall risk. The current proof-of-concept study evaluated the feasibility of using a chest-worn sensor during hospitalization to determine fall risk. Physical activity and heart rate variability (HRV) of 31 volunteers admitted to a 29-bed adult inpatient unit were recorded using a single chest-worn sensor. Sensor data during the first 24-hour recording were analyzed. Participants were stratified using the Hendrich II fall risk assessment into high and low fall risk groups. Univariate analysis revealed age, daytime activity, nighttime side lying posture, and HRV were significantly different between groups. Results suggest feasibility of wearable technology to consciously monitor physical activity, sleep postures, and HRV as potential markers of fall risk in the acute care setting. Further study is warranted to confirm the results and examine the efficacy of the proposed wearable technology to manage falls in hospitals. [Journal of Gerontological Nursing, 43(7), 53-62.].

Modeling subjective evaluation of soundscape quality in urban open spaces: An artificial neural network approach.

PubMed

Yu, Lei; Kang, Jian

2009-09-01

This research aims to explore the feasibility of using computer-based models to predict the soundscape quality evaluation of potential users in urban open spaces at the design stage. With the data from large scale field surveys in 19 urban open spaces across Europe and China, the importance of various physical, behavioral, social, demographical, and psychological factors for the soundscape evaluation has been statistically analyzed. Artificial neural network (ANN) models have then been explored at three levels. It has been shown that for both subjective sound level and acoustic comfort evaluation, a general model for all the case study sites is less feasible due to the complex physical and social environments in urban open spaces; models based on individual case study sites perform well but the application range is limited; and specific models for certain types of location/function would be reliable and practical. The performance of acoustic comfort models is considerably better than that of sound level models. Based on the ANN models, soundscape quality maps can be produced and this has been demonstrated with an example.

To examine the association between objectively measured physical activity and depression symptoms among a nationally representative sample of pregnant women to provide a more accurate understanding of the relationship between physical activity and depression symptoms. We employed a cross-sectional study design. Data from the National Health and Nutrition Examination Survey 2005-2006 were used for this study. One-hundred and forty-one pregnant women wore an ActiGraph accelerometer for 7 days and completed the Patient Health Questionnaire-9 to assess depression status. More than 19% of the participants experienced some depression symptoms, and compared to their counterparts not having depression symptoms, they were less physically active. An inverse association was found between physical activity and depression symptoms among pregnant women. When feasible, nurses are encouraged to help facilitate physical activity among pregnant women, assuming an uncomplicated pregnancy. © 2012 AWHONN, the Association of Women's Health, Obstetric and Neonatal Nurses.

Physical and psychological challenges can arise from paediatric injury, which can impact child health outcomes. Evidence-based resources to promote recovery are limited. The low cost, portable Cellie Coping Kit for Children with Injury provides evidence-based strategies to help children manage injury-related challenges. This study aimed to describe intervention feasibility and explore initial outcomes (learning, quality of life [QOL], and trauma symptoms). Three independent pilot studies were conducted. Child-parent dyads (n = 61) participated in the intervention; ~36% completed a 4-week follow-up assessment. Results suggested that the intervention was feasible (e.g., 95% of parents would recommend the intervention; >85% reported that it was easy to use). Over 70% of participants reported learning new skills. No statistically significant differences were detected for children's QOL or trauma symptoms preintervention to postintervention. Preliminary research suggests that the Cellie Coping Kit for Children with Injuries is a feasible, low-cost, preventive intervention, which may provide families with strategies to promote recovery from paediatric injury. Future research, including a randomized controlled trial, ought to further examine targeted long-term intervention outcomes. © 2018 John Wiley & Sons Ltd.

Dance can be a promising treatment intervention used in rehabilitation for individuals with disabilities to address physical, cognitive and psychological impairments. The aim of this pilot study was to determine the feasibility of a modified dance intervention as an adjunct therapy designed for people with subacute stroke, in a rehabilitation setting. Using a descriptive qualitative study design, a biweekly 45-min dance intervention was offered to individuals with a subacute stroke followed in a rehabilitation hospital, over 4 weeks. The dance intervention followed the structure of an usual dance class, but the exercises were modified and progressed to meet each individual’s needs. The dance intervention, delivered in a group format, was feasible in a rehabilitation setting. A 45-min dance class of moderate intensity was of appropriate duration and intensity for individuals with subacute stroke to avoid excessive fatigue and to deliver the appropriate level of challenge. The overall satisfaction of the participants towards the dance class, the availability of space and equipment, and the low level of risks contributed to the feasibility of a dance intervention designed for individuals in the subacute stage of post-stroke recovery.

Persons with dementia (PWD) are known to have difficulty with participation and focus during physical activity. Virtual reality (VR) offers a unique medium for motor learning but has only been used previously for cognitive assessment for PWD. Our study had two objectives: (1) investigate the feasibility and safety of an exercise-based VR training program in PWD, and (2) investigate its effects on balance and mobility. The intervention consisted of daily (5 d/wk, 1 h each) VR training sessions for 2 wk for a single research participant. Clinical balance and mobility measures were assessed 1 wk prior to, during, 1 wk following, and 1 mo after the intervention. Postintervention interviews provided qualitative feedback from the participant and his caregivers. Results indicate that VR training is feasible, safe, and enjoyable for PWD. However, balance and mobility measures were unaffected. VR training is well tolerated in a single research participant with dementia and is an engaging medium for participation in exercise.

Preference-based tempo-pace synchronized music has been shown to reduce perceived physical activity exertion and improve exercise performance. The extent to which such strategies can improve adherence to physical activity remains unknown. The objective of the study is to explore the feasibility and efficacy of tempo-pace synchronized preference-based music audio-playlists on adherence to physical activity among cardiovascular disease patients participating in a cardiac rehabilitation. Thirty-four cardiac rehabilitation patients were randomly allocated to one of two strategies: (1) no music usual-care control and (2) tempo-pace synchronized audio-devices with personalized music playlists + usual-care. All songs uploaded onto audio-playlist devices took into account patient personal music genre and artist preferences. However, actual song selection was restricted to music whose tempos approximated patients' prescribed exercise walking/running pace (steps per minute) to achieve tempo-pace synchrony. Patients allocated to audio-music playlists underwent further randomization in which half of the patients received songs that were sonically enhanced with rhythmic auditory stimulation (RAS) to accentuate tempo-pace synchrony, whereas the other half did not. RAS was achieved through blinded rhythmic sonic-enhancements undertaken manually to songs within individuals' music playlists. The primary outcome consisted of the weekly volume of physical activity undertaken over 3 months as determined by tri-axial accelerometers. Statistical methods employed an intention to treat and repeated-measures design. Patients randomized to personalized audio-playlists with tempo-pace synchrony achieved higher weekly volumes of physical activity than did their non-music usual-care comparators (475.6 min vs. 370.2 min, P  < 0.001). Improvements in weekly physical activity volumes among audio-playlist recipients were driven by those randomized to the RAS group which attained weekly exercise volumes that were nearly twofold greater than either of the two other groups (average weekly minutes of physical activity of 631.3 min vs. 320 min vs. 370.2 min, personalized audio-playlists with RAS vs. personalized audio-playlists without RAS vs. non-music usual-care controls, respectively, P  < 0.001). Patients randomized to music with RAS utilized their audio-playlist devices more frequently than did non-RAS music counterparts ( P  < 0.001). The use of tempo-pace synchronized preference-based audio-playlists was feasibly implemented into a structured exercise program and efficacious in improving adherence to physical activity beyond the evidence-based non-music usual standard of care. Larger clinical trials are required to validate these findings. ClinicalTrials.gov ID (NCT01752595).

An employer offer of temporary job modification is a key strategy for facilitating return-to-work for musculoskeletal conditions, but there are no validated scales to assess the level of support for temporary job modifications across a range of job types and organizations. To pilot test a new 21-item self-report measure [the Job Accommodation Scale (JAS)] to assess its applicability, internal consistency, factor structure, and relation to physical job demands. Supervisors (N = 804, 72.8 % male, mean age = 46) were recruited from 19 employment settings in the USA and Canada and completed a 30-min online survey regarding job modification practices. As part of the survey, supervisors nominated and described a job position they supervised and completed the JAS for a hypothetical worker (in that position) with an episode of low back pain. Job characteristics were derived from the occupational informational network job classification database. The full response range (1-4) was utilized on all 21 items, with no ceiling or floor effects. Avoiding awkward postures was the most feasible accommodation and moving the employee to a different site or location was the least feasible. An exploratory factor analysis suggested five underlying factors (Modify physical workload; Modify work environment; Modify work schedule; Find alternate work; and Arrange for assistance), and there was an acceptable goodness-of-fit for the five parceled sub-factor scores as a single latent construct in a measurement model (structural equation model). Job accommodations were less feasible for more physical jobs and for heavier industries. The pilot administration of the JAS with respect to a hypothetical worker with low back pain showed initial support for its applicability, reliability, and validity when administered to supervisors. Future studies should assess its validity for use in actual disability cases, for a range of health conditions, and to assess different stakeholder opinions about the feasibility of job accommodation strategies.

INTRODUCTION An employer offer of temporary job modification is a key strategy for facilitating return-to-work (RTW) for musculoskeletal conditions, but there are no validated scales to assess the level of support for temporary job modifications across a range of job types and organizations. OBJECTIVE To pilot test a new 21-item self-report measure (the Job Accommodation Scale [JAS]) to assess its applicability, internal consistency, factor structure, and relation to physical job demands.

Background For individuals, especially older adults, playing video games is a promising tool for improving their driving skills. The ease of use, wide availability, and interactivity of gaming consoles make them an attractive simulation tool. Objective The objective of this study was to look at the feasibility and effects of installing video game consoles in the homes of individuals looking to improve their driving skills. Methods A systematic literature review was conducted to assess the effect of playing video games on improving driving skills. An observatory study was performed to evaluate the feasibility of using an Xbox 360 Kinect console for improving driving skills. Results Twenty–nine articles, which discuss the implementation of video games in improving driving skills were found in literature. On our study, it was found the Xbox 360 with Kinect is capable of improving physical and mental activities. Xbox Video games were introduced to engage players in physical, visual and cognitive activities including endurance, postural sway, reaction time, eyesight, eye movement, attention and concentration, difficulties with orientation, and semantic fluency. However, manual dexterity, visuo-spatial perception and binocular vision could not be addressed by these games. It was observed that Xbox Kinect (by incorporating Kinect sensor facilities) combines physical, visual and cognitive engagement of players. These results were consistent with those from the literature review. Conclusions From the research that has been carried out, we can conclude that video game consoles are a viable solution for improving user’s physical and mental state. In future we propose to carry a thorough evaluation of the effects of video games on driving skills in elderly people. PMID:25654355

Patients after Fontan operation for complex congenital heart disease (CHD) have decreased exercise capacity and report reduced health-related quality of life (HRQOL). Studies suggest hospital-based cardiac physical activity programs can improve HRQOL and exercise capacity in patients with CHD; however, these programs have variable adherence rates. The impact of a home-based cardiac physical activity program in Fontan survivors is unclear. This pilot study evaluated the safety, feasibility, and benefits of an innovative home-based physical activity program on HRQOL in Fontan patients. A total of 14 children, 8-12 years, with Fontan circulation enrolled in a 12-week moderate/high intensity home-based cardiac physical activity program, which included a home exercise routine and 3 formalized in-person exercise sessions at 0, 6, and 12 weeks. Subjects and parents completed validated questionnaires to assess HRQOL. The Shuttle Test Run was used to measure exercise capacity. A Fitbit Flex Activity Monitor was used to assess adherence to the home activity program. Of the 14 patients, 57% were male and 36% had a dominant left ventricle. Overall, 93% completed the program. There were no adverse events. Parents reported significant improvement in their child's overall HRQOL (P < .01), physical function (P < .01), school function (P = .01), and psychosocial function (P < .01). Patients reported no improvement in HRQOL. Exercise capacity, measured by total shuttles and exercise time in the Shuttle Test Run and calculated VO2 max, improved progressively from baseline to the 6 and 12 week follow up sessions. Monthly Fitbit data suggested adherence to the program. This 12-week home-based cardiac physical activity program is safe and feasible in preteen Fontan patients. Parent proxy-reported HRQOL and objective measures of exercise capacity significantly improved. A 6-month follow up session is scheduled to assess sustainability. A larger study is needed to determine the applicability and reproducibility of these findings in other age groups and forms of complex CHD. © 2016 Wiley Periodicals, Inc.

Introduction Early exercise with in-bed cycling as part of an intensive care unit (ICU) rehabilitation programme has the potential to improve physical and functional outcomes following critical illness. The objective of this study is to determine the feasibility of enrolling adults in a multicentre pilot randomised clinical trial (RCT) of early in-bed cycling versus routine physiotherapy to inform a larger RCT. Methods and analysis 60-patient parallel group pilot RCT in 7 Canadian medical-surgical ICUs. We will include all previously ambulatory adult patients within the first 0–4 days of mechanical ventilation, without exclusion criteria. After informed consent, patients will be randomised using a web-based, centralised electronic system, to 30 min of in-bed leg cycling in addition to routine physiotherapy, 5 days per week, for the duration of their ICU stay (28 days maximum) or routine physiotherapy alone. We will measure patients' muscle strength (Medical Research Council Sum Score, quadriceps force) and function (Physical Function in ICU Test (scored), 30 s sit-to-stand, 2 min walk test) at ICU awakening, ICU discharge and hospital discharge. Our 4 feasibility outcomes are: (1) patient accrual of 1–2 patients per month per centre, (2) protocol violation rate <20%, (3) outcome measure ascertainment >80% at the 3 time points and (4) blinded outcomes ascertainment >80% at hospital discharge. Hospital outcome assessors are blinded to group assignment, whereas participants, ICU physiotherapists, ICU caregivers, research coordinators and ICU outcome assessors are not blinded to group assignment. We will analyse feasibility outcomes with descriptive statistics. Ethics and dissemination Each participating centre will obtain local ethics approval, and results of the study will be published to inform the design and conduct of a future multicentre RCT of in-bed cycling to improve physical outcomes in ICU survivors.

2017-08-01

Rehabilitation after lower-extremity fractures is based on the physicians' recommendation for non-, partial-, or full weight-bearing. Clinical studies rely on this assumption, but continuous compliance or objective loading rates are unknown. The purpose of this study was to determine the compliance to weight-bearing recommendations by introducing a novel, pedobarography system continuously registering postoperative ground forces into ankle, tibial shaft and proximal femur fracture aftercare and test its feasibility for this purpose. In this prospective, observational study, a continuously measuring pedobarography insole was placed in the patients shoe during the immediate post-operative aftercare after ankle, tibial shaft and intertrochanteric femur fractures. Weight-bearing was ordered as per the institutional standard and controlled by physical therapy. The insole was retrieved after a maximum of six weeks (28 days [range 5-42 days]). Non-compliance was defined as a failure to maintain, or reach the ordered weight-bearing within 30%. Overall 30 patients were included in the study. Fourteen (47%) of the patients were compliant to the weight-bearing recommendations. Within two weeks after surgery patients deviated from the recommendation by over 50%. Sex, age and weight did not influence the performance (p > 0.05). Ankle fracture patients (partial weight-bearing) showed a significantly increased deviation from the recommendation (p = 0.01). Our study results show that, despite physical therapy training, weight-bearing compliance to recommended limits was low. Adherence to the partial weight-bearing task was further decreased over time. Uncontrolled weight-bearing recommendations should thus be viewed with caution and carefully considered as fiction. The presented insole is feasible to determine weight bearing continuously, could immediately help define real-time patient behaviour and establish realistic, individual weight-bearing recommendations.

Soil-transmitted helminth infections and physical fitness in school-aged Bulang children in southwest China: results from a cross-sectional survey

PubMed Central

2012-01-01

Background Chronic soil-transmitted helminth (STH) infections have been associated with reduced physical fitness, but available evidence is limited. The aim of this cross-sectional survey was to assess the feasibility of measuring children's physical fitness and to relate it to STH infections. Our study was carried out among school-aged children of the Bulang ethnic group in rural southwest People's Republic of China (P.R. China). Standardized, quality-controlled methods were employed to determine STH infections (Kato-Katz technique), haemoglobin levels, anthropometry (body weight and height) and physical fitness (20-m shuttle run test). Results A compliance of 87% suggested good acceptance of the methods used. Among 69 children with complete data records, infection prevalence of Trichuris trichiura, Ascaris lumbricoides and hookworm were 81%, 44% and 6%, respectively. The maximum volume of oxygen that can be utilized within 1 min during exhaustive exercise (VO2 max estimate) of T. trichiura-infected children was 1.94 ml kg-1 min-1 lower than that of their non-infected counterparts (P = 0.005). Until exhaustion, T. trichiura-infected children had completed 6.14 20-m laps less (P = 0.004). Additionally, the mean VO2 max estimate of stunted children was lowered by 1.63 ml kg-1 min-1 (P = 0.002) and they completed 5.32 20-m laps less (P = 0.001) compared to children of normal stature. No significant association between stunting and infection with any STH species could be established. Conclusions Implementation of physical fitness tests in rural, resource-constraint settings is feasible. The physical fitness of children who are stunted or infected with STHs, particularly T. trichiura, is significantly impaired. We have launched a larger study and will determine the dynamics of school-aged children's physical fitness over a 7-month period after administration of anthelminthic drugs. PMID:22424138

Probing Majorana modes in the tunneling spectra of a resonant level.

Unambiguous identification of Majorana physics presents an outstanding problem whose solution could render topological quantum computing feasible. We develop a numerical approach to treat finite-size superconducting chains supporting Majorana modes, which is based on iterative application of a two-site Bogoliubov transformation. We demonstrate the applicability of the method by studying a resonant level attached to the superconductor subject to external perturbations. In the topological phase, we show that the spectrum of a single resonant level allows us to distinguish peaks coming from Majorana physics from the Kondo resonance.

The number of older adults with dementia is expected to increase. Dementia is not only characterized by a decline in cognition, also other functions, for example, physical functioning change. A possible means to decrease the decline in these functions, or even improve them, could be increasing the amount of physical activity. A feasible way hereto may be activation of the mirror neuron system through action observation. This method has already been shown beneficial for the performance of actions in, for example, stroke patients. The primary aim of this study is to examine the effect of observing videos of walking people on physical activity and physical performance, in older adults with dementia. Secondary, effects on cognition and quality of life related factors will be examined. A cluster randomized controlled trial is being performed, in which videos are shown to older adults with dementia (also additional eligibility criteria apply) in shared living rooms of residential care facilities. Due to the study design, living rooms instead of individual participants are randomly assigned to the experimental (videos of walking people) or control (videos of nature) condition, by means of drawing pieces of paper. The intervention has a duration of three months, and takes place on weekdays, during the day. There are four measurement occasions, in which physical activity, physical functioning, activities of daily living, cognition, the rest-activity rhythm, quality of life, and depression are assessed. Tests for participants are administered by a test administrator who is blind to the group the participant is in. This study examines the effect of the observation of walking people on multiple daily life functions and quality of life related factors in older adults with dementia. A strength of this study is that the intervention does not require much time and attention from caregivers or researchers. A challenge of the study is therefore to get to know for how long residents watch the videos. However, the design implies a high feasibility of the study, as well as a high applicability of the intervention into daily care. NTR4708. Date of registration: 31 July 2014.

Faith-based programs have shown beneficial effects for health and behaviors. Few have specifically intervened on the spiritual, mental (i.e., stress), and physical dimensions of well-being combined for health and healthy behaviors (i.e., exercise and diet). The purpose of this report is to describe the feasibility of executing a spirituality-based health behavior change, program founded upon the Spiritual Framework of Coping. This study was a quasi-experimental one group pretest-posttest design. Feasibility objectives were assessed, and limited efficacy of pretest and posttest measures was analyzed using paired t test (p < .05). Acceptance of the program was positive, and modest demand was shown with initial interest and an average attendance of 78.7%. The program was successfully implemented as shown by meeting session objectives and 88% homework completion. The program was practical for the intended participants and was successfully integrated within the existing environment. Limited efficacy measures showed no pre-post changes. This study provided preliminary support for the design and further testing of the theoretical components of the Spiritual Framework of Coping that informed the program.

Little is known about the effectiveness of self-determination theory (SDT), a representative motivational theory, on exercise domain in older adults. This feasibility study used quantitative and qualitative approaches to evaluate the effectiveness of a 13-month group exercise program applying SDT-based motivational strategies on exercise adherence, physical fitness, and quality of life, and to explore factors affecting exercise adherence in South Korean older adults (N = 18). Exercise attendance rate was high (82.52%). There were significant differences in aerobic endurance (p < .001), lower body strength (p < .05), dynamic balance (p < .001), and perceived social functioning (p < .05) at 13 months compared with baseline. Factors affecting exercise adherence were related to the SDT-based motivational strategies. These results support the importance of health professionals applying SDT-based motivational strategies to exercise programs to help facilitate motivation for participation and to promote physical fitness and quality of life in older adults.

Falls are a common cause of injury in older adults, with the prevention of falls being a priority for public health departments around the world. This study investigated the feasibility, and impact of an 8 week contemporary dance programme on modifiable physical (physical activity status, mobility, sedentary behaviour patterns) and psychosocial (depressive state, fear of falling) risk factors for falls. An uncontrolled 'pre-post' intervention design was used. Three groups of older (60 yrs.+) adults were recruited from local community groups to participate in a 3 separate, 8 week dance programmes. Each programme comprised two, 90 min dance classes per week. Quantitative measures of physical activity, sedentary behaviour, depression, mobility and fear of falling were measured at baseline (T1) and after 8 weeks of dance (T2). Weekly attendance was noted, and post-study qualitative work was conducted with participants in 3 separate focus groups. A combined thematic analysis of these data was conducted. Of the 38 (Mean Age = 77.3 ± 8.4 yrs., 37 females) who attended the dance sessions, 22 (21 females; 1 male; mean age = 74.8, ±8.44) consented to be part of the study. Mean attendance was 14.6 (±2.6) sessions, and mean adherence was 84.3% (±17). Significant increases in moderate and vigorous physical activity were noted, with a significant decrease in sitting time over the weekdays (p < 0.05). Statistically significant decreases in the mean Geriatric Depression Scale (p < 0.05) and fear of falling (p < 0.005) score were noted, and the time taken to complete the TUG test decreased significantly from 10.1 s to 7.7 s over the 8 weeks (p < 0.005). Themes from the focus groups included the dance programme as a means of being active, health Benefits, and dance-related barriers and facilitators. The recruitment of older adults, good adherence and favourability across all three sites indicate that a dance programme is feasible as an intervention, but this may be limited to females only. Contemporary dance has the potential to positively affect the physical activity, sitting behaviour, falls related efficacy, mobility and incidence of depression in older females which could reduce their incidence of falls. An adequately powered study with control groups are required to test this intervention further.

Obesity is a growing global health concern that may lead to cardiovascular disease, type II diabetes, and cancer. Several systematic reviews have shown that technology is successful in combating obesity through increased physical activity, but there is no known review on interventions that use an electronic activity monitor system (EAMS). EAMSs are defined as a wearable device that objectively measures lifestyle physical activity and can provide feedback, beyond the display of basic activity count information, via the monitor display or through a partnering application to elicit continual self-monitoring of activity behavior. These devices improve upon standard pedometers because they have the ability to provide visual feedback on activity progression, verbal encouragement, and social comparison. This systematic review aimed to synthesize the efficacy and feasibility results of EAMSs within published physical activity interventions. Electronic databases and journal references were searched for relevant articles. Data sources included CINAHL, Cochrane CENTRAL, Medline Ovid, PsycINFO, and clinicaltrials.gov. Out of the 1,574 retrieved, 11 articles met the inclusion criteria. These articles were reviewed for quality and content based on a risk of bias tool and intervention components. Most articles were determined to be of medium quality while two were of low quality, and one of high quality. Significant pre-post improvements in the EAMS group were found in five of nine studies for physical activity and in four of five studies for weight. One found a significant increase in physical activity and two studies found significant weight loss in the intervention group compared with the comparator group. The EAMS interventions appear to be feasible with most studies reporting continual wear of the device during waking hours and a higher retention rate of participants in the EAMS groups. These studies provide preliminary evidence suggesting that EAMS can increase physical activity and decrease weight significantly, but their efficacy compared to other interventions has not yet been demonstrated. More high-quality randomized controlled trials are needed to evaluate the overall effect of EAMS, examine which EAMS features are most effective, and determine which populations are most receptive to an EAMS.

Orbital angular momentum of light is a fundamental optical degree of freedom characterized by unlimited number of available angular momentum states. Although this unique property has proved invaluable in diverse recent studies ranging from optical communication to quantum information, it has not been considered useful or even relevant for simulating nontrivial physics problems such as topological phenomena. Contrary to this misconception, we demonstrate the incredible value of orbital angular momentum of light for quantum simulation by showing theoretically how it allows to study a variety of important 2D topological physics in a 1D array of optical cavities. This application for orbital angular momentum of light not only reduces required physical resources but also increases feasible scale of simulation, and thus makes it possible to investigate important topics such as edge-state transport and topological phase transition in a small simulator ready for immediate experimental exploration.

Several data suggest that physical activity and cognitive stimulation have a positive effect on the quality of life (QoL) of people with Alzheimer's disease (AD), slowing the decline due to the disease. A pilot project was undertaken to assess the effect of cognitive stimulation, physical activity, and socialization on patients with AD and their informal caregiver's QoL and mood. Fourteen patients with AD were randomly divided into active treatment group and control group. At the end of treatment, a significant improvement in apathy, anxiety, depression, and QoL in the active treatment group was found. Considering caregivers, those of the active treatment group exhibited a significant improvement in their mood and in their perception of patients' QoL. This study provides evidence that a combined approach based on cognitive stimulation, physical activity, and socialization is a feasible tool to improve mood and QoL in patients with AD and their caregivers.

Enabled by petascale supercomputing, the next generation of computer models for wind energy will simulate a vast range of scales and physics, spanning from turbine structural dynamics and blade-scale turbulence to mesoscale atmospheric flow. A single model covering all scales and physics is not feasible. Thus, these simulations will require the coupling of different models/codes, each for different physics, interacting at their domain boundaries.

We outline the case for heavy-ion-physics studies using the multi-TeV lead LHC beams in the fixed-target mode. After a brief contextual reminder, we detail the possible contributions of AFTER@LHC to heavy-ion physics with a specific emphasis on quarkonia. We then present performance simulations for a selection of observables. These show that Υ (nS), J/ψ and ψ (2S) production in heavy-ion collisions can be studied in new energy and rapidity domains with the LHCb and ALICE detectors. We also discuss the relevance to analyse the Drell-Yan pair production in asymmetric nucleus-nucleus collisions to study the factorisation of the nuclear modification of partonic densities and of further quarkonium states to restore their status of golden probes of the quark-gluon plasma formation.

Objective To determine whether Adaptive Physical Activity (APA-stroke), a community-based exercise program for participants with hemiparetic stroke, improves function in the community. Methods Nonrandomized controlled study in Tuscany, Italy, of participants with mild to moderate hemiparesis at least 9 months after stroke. Forty-nine participants in a geographic health authority (Empoli) were offered APA-stroke (40 completed the study). Forty-four control participants in neighboring health authorities (Florence and Pisa) received usual care (38 completed the study). The APA intervention was a community-based progressive group exercise regimen that included walking, strength, and balance training for 1 hour, thrice a week, in local gyms, supervised by gym instructors. No serious adverse clinical events occurred during the exercise intervention. Outcome measures included the following: 6-month change in gait velocity (6-Minute Timed Walk), Short Physical Performance Battery (SPPB), Berg Balance Scale, Stroke Impact Scale (SIS), Barthel Index, Hamilton Rating Scale for Depression, and Index of Caregivers Strain. Results After 6 months, the intervention group improved whereas controls declined in gait velocity, balance, SPPB, and SIS social participation domains. These between-group comparisons were statistically significant at P < .00015. Individuals with depressive symptoms at baseline improved whereas controls were unchanged (P < .003). Oral glucose tolerance tests were performed on a subset of participants in the intervention group. For these individuals, insulin secretion declined 29% after 6 months (P = .01). Conclusion APA-stroke appears to be safe, feasible, and efficacious in a community setting. PMID:19318465

Yoga can be an effective intervention for physical and psychological symptoms and decreased ability to cope with physical, emotional, vocational, or academic stress. One group of individuals challenged regarding adequate self-care in the face of stress are personnel in university training programs for helping professions (e.g., psychology, nursing, nutrition). This feasibility study explored engagement in and effectiveness of a systematic 10-week yoga program aimed at university faculty, staff, and students. The intervention consisted of 10 weekly 90-minute sessions that were structured to include conceptual grounding, breathing, postures, and meditation. Weekly class outlines were made available to students for home practice. Participants signed informed consents, liability waivers, and health screenings. Self-reports of home practice, barriers to practice, perceived stress, and stress symptoms were used to evaluate whether the intervention was successful in engaging participants and reducing stress-related symptoms. Engagement was demonstrated by study adherence in the first 10-week series (88%; 44 of 50 enrolled), as well as re-enrollment for at least one additional 10-week series (64%; 28 of 44). Intervention success was demonstrated through repeated measure s ANOVAs of 44 participants' data, which showed significant improvement after a single 10-week series in perceived stress, as well as self-reported psychological, behavioral, and physical symptoms of stress. The study demonstrates feasibility of a yoga intervention in an academic setting and provides preliminary evidence for efficacy in stress reduction. It also supplies 10 detailed session protocols for intervention replication.

To construct patient-specific physical three-dimensional (3D) models of renal units with materials that approximates the properties of renal tissue to allow pre-operative and robotic training surgical simulation, 3D physical kidney models were created (3DSystems, Rock Hill, SC) using computerized tomography to segment structures of interest (parenchyma, vasculature, collection system, and tumor). Images were converted to a 3D surface mesh file for fabrication using a multi-jet 3D printer. A novel construction technique was employed to approximate normal renal tissue texture, printers selectively deposited photopolymer material forming the outer shell of the kidney, and subsequently, an agarose gel solution was injected into the inner cavity recreating the spongier renal parenchyma. We constructed seven models of renal units with suspected malignancies. Partial nephrectomy and renorrhaphy were performed on each of the replicas. Subsequently all patients successfully underwent robotic partial nephrectomy. Average tumor diameter was 4.4 cm, warm ischemia time was 25 min, RENAL nephrometry score was 7.4, and surgical margins were negative. A comparison was made between the seven cases and the Tulane Urology prospectively maintained robotic partial nephrectomy database. Patients with surgical models had larger tumors, higher nephrometry score, longer warm ischemic time, fewer positive surgical margins, shorter hospitalization, and fewer post-operative complications; however, the only significant finding was lower estimated blood loss (186 cc vs 236; p = 0.01). In this feasibility study, pre-operative resectable physical 3D models can be constructed and used as patient-specific surgical simulation tools; further study will need to demonstrate if this results in improvement of surgical outcomes and robotic simulation education.

Increasing physical activity (PA) brings many health benefits, but engaging people in higher levels of PA after their 60s is not straightforward. The Functional Fitness MOT (FFMOT) is a new approach which aims to raise awareness about the importance of components of fitness (strength, balance, flexibility), highlight benefits of PA, engages older people in health behavior change discussions, and directs them to local activity resources. This battery of tests combined with a brief motivational interview has not been tested in terms of feasibility or effectiveness. To assess whether the FFMOT, provided in a health care setting, is appealing to older patients of a community physiotherapy service and to understand the views and perceptions of the older people undergoing the FFMOT regarding the intervention, as well as the views of the physiotherapy staff delivering the intervention. Secondary aims are to assess the feasibility of carrying out a phase 2 pilot randomized controlled trial of the FFMOT, in the context of a community physiotherapy service, by establishing whether enough patients can be recruited and retained in the study, and enough outcome data can be generated. A mixed-methods feasibility study will be conducted in two physiotherapy outpatient clinics in the United Kingdom. A total of 30 physically inactive, medically stable older adults over the age of 60 will be provided with an individual FFMOT, comprising a set of six standardized, validated, age-appropriate tests aimed at raising awareness of the different components of fitness. The results of these tests will be used to provide the participants with feedback on performance in comparison to sex and age-referenced norms. This will be followed by tailored advice on how to become more active and improve fitness, including advice on local opportunities to be more active. Subsequently, participants will be invited to attend a focus group to discuss barriers and motivators to being more active, health behavior change, and the scope for individuals to improve their PA levels. To inform the design of a future trial, descriptive (eg, recruitment and retention rates), quantitative (Community Healthy Activities Model Program for Seniors; CHAMPS physical activity questionnaire), and qualitative data (focus group discussions, semi-structured staff interviews) will be collected. Recruitment and enrolment for the trial started in September 2015. Follow-up will be completed in June 2016. Results are expected to be available at the end of 2016. Allied health professionals play a key role in encouraging older adults to increase their PA, but with little evidence on how best to do this within their clinical practice. The purpose of this feasibility study is to examine the introduction of a new service: The FFMOT. The views and perceptions of the older people undergoing the FFMOT and relating to its delivery in clinical practice will be explored. Data, which will inform the feasibility of a randomized controlled trial of effectiveness of the FFMOT in promoting improved PA, will be reported.

Work-related stress and associated illness and burnout is rising in western society, with now as much as almost a quarter of European and half of USA's employees estimated to be at the point of burnout. Mindfulness meditation, yoga, and physical exercise have all shown beneficial effects for work-related stress and illness. This proof of concept study assessed the feasibility, acceptability, and preliminary effects of the newly developed Mindful2Work training, a combination of physical exercise, restorative yoga, and mindfulness meditations, delivered in six weekly group sessions plus a follow-up session. Participants ( n  = 26, four males), referred by company doctors with (work-related) stress and burnout complaints, completed measurements pre and post the intervention, as well as at 6-week (FU1) and 6-month (FU2) follow-up. Results showed very high feasibility and acceptability of the Mindful2Work training. The training and trainers were rated with an 8.1 and 8.4 on a 1-10 scale, respectively, and training dropout rate was zero. Significant improvements with (very) large effect sizes were demonstrated for the primary outcome measures of physical and mental workability, and for anxiety, depression, stress, sleep quality, positive and negative affect, which remained (very) large and mostly increased further over time. Risk for long-term dropout from work (checklist individual strength [CIS]) was 92 % at pre-test, reduced to 67 % at post-test, to 44 % at FU1, and 35 % at FU2, whereas employees worked (RTWI) 65 % of their contract hours per week at pre-test, which increased to 73 % at post-test, 81 % at FU1 and 93 % at FU2. Intensity of home practice or number of attended sessions were not related to training effects. To conclude, the newly developed Mindful2Work training seems very feasible, and acceptable, and although no control group was included, the large effects of Mindful2Work are highly promising.

Depression is associated with physical inactivity, which may mediate the relationship between depression and a range of chronic physical health conditions. However, few interventions have combined a psychological intervention for depression with behaviour change techniques, such as behavioural activation (BA), to promote increased physical activity. To determine procedural and clinical uncertainties to inform a definitive randomised controlled trial (RCT), a pilot parallel-group RCT was undertaken within two Improving Access to Psychological Therapies (IAPT) services in South West England. We aimed to recruit 80 adults with depression and randomise them to a supported, written self-help programme based on either BA or BA plus physical activity promotion (BAcPAc). Data were collected at baseline and 4 months post-randomisation to evaluate trial retention, intervention uptake and variance in outcomes to inform a sample size calculation. Qualitative data were collected from participants and psychological wellbeing practitioners (PWPs) to assess the acceptability and feasibility of the trial methods and the intervention. Routine data were collected to evaluate resource use and cost. Sixty people with depression were recruited, and a 73 % follow-up rate was achieved. Accelerometer physical activity data were collected for 64 % of those followed. Twenty participants (33 %) attended at least one treatment appointment. Interview data were analysed for 15 participants and 9 study PWPs. The study highlighted the challenges of conducting an RCT within existing IAPT services with high staff turnover and absences, participant scheduling issues, PWP and participant preferences for cognitive focussed treatment, and deviations from BA delivery protocols. The BAcPAc intervention was generally acceptable to patients and PWPs. Although recruitment procedures and data collection were challenging, participants generally engaged with the BAcPAc self-help booklets and reported willingness to increase their physical activity. A number of feasibility issues were identified, in particular the under-use of BA as a treatment for depression, the difficulty that PWPs had in adapting their existing procedures for study purposes and the instability of the IAPT PWP workforce. These problems would need to be better understood and resolved before proceeding to a full-scale RCT. ISRCTN74390532 . Registered on 26 March 2013.

Restaurant workers are a large population at high risk for tobacco use, physical inactivity, and influenza. They are difficult to reach with health care interventions and may be more accessible through workplaces, yet few studies have explored the feasibility of workplace health promotion in this population. This study sought to identify barriers and facilitators to promotion of tobacco cessation, physical activity, and influenza vaccination in restaurants. Moderators conducted 7 focus groups, 3 with restaurant owners and managers, 2 with English-speaking workers, and 2 with Spanish-speaking workers. All groups were recorded, and recordings were transcribed and uploaded to qualitative-analysis software. Two researchers coded each transcript independently and analyzed codes and quotations for common themes. Seventy people from the restaurant industry participated. Barriers to workplace health promotion included smoking-break customs, little interest in physical activity outside of work, and misinformation about influenza vaccinations. Facilitators included creating and enforcing equitable break policies and offering free, on-site influenza vaccinations. Spanish-speakers were particularly amenable to vaccination, despite their perceptions of low levels of management support for health promotion overall. Owners required a strong business case to consider investing in long-term prevention for their employees. Tobacco cessation and influenza vaccinations are opportunities for health promotion among restaurant workers, whereas physical activity interventions face greater challenges. Promotion of equitable breaks, limited smoking-break policies, and free, on-site influenza vaccinations could improve health for restaurant workers, who often do not have health insurance. Workplace interventions may be particularly important for Hispanic workers who have additional access barriers.

External rotation ROM as well as extensor and abductor muscle strength significantly improved 6 months after treatment compared with that before treatment (P<.05). Significant improvements were also seen in physical function, role physical, and bodily pain subgroup scores of the SF-36 (P<.05). No serious adverse events occurred. This study demonstrates the feasibility and safety of a multiplex rehabilitation program after MSC transplantation and provides support for further study on the benefits of rehabilitation programs in regenerative medicine.

We report the results of a study into the feasibility of conducting the ELISE and EXL experiments on collisions of nuclei of radioactive fragments with electrons at the Institute for Theoretical and Experimental Physics (ITEP). A scheme for uranium ion acceleration in the ITEP accelerator complex is chosen, and it is shown that uranium ions may be accelerated with an intensity of ˜1 × 1011 ions/s as soon as the complex is modified and a new injector is constructed. The basic parameters of the modified complex are given, and a layout diagram indicating the positions of the target that serves to produce radioactive fragments, the separator, and the storage rings (CR, RESR, NESR, and ER) at the ITEP site is presented.

The purpose of this feasibility study was to investigate whether Māori of advanced age would be interested in and able to take part in a quantitative study involving a comprehensive questionnaire, physical health assessment and blood analyses (a range of biological markers). The study also aimed to involve older Māori in all stages: development of research questions, review of assessment techniques and interpretation of results. Māori aged 75-79 years living in the Bay of Plenty and Lakes DHB areas were invited to participate in a feasibility study covering a wide range of quantitative health related questions. After informed consent interviews and physical assessments were conducted in participants' homes or at a local clinic by Māori health providers contracted as a research partner. For those who gave informed consent specifically for blood analyses, bloods were taken and analysed for defined biological markers of inflammation and ageing. All physical assessments and blood analyses were forwarded to each participant's own general practitioner and relevant guidance was given by the research team. Collective results from 33 Māori participants are presented and cover: Te Reo Māori me ona tikanga (Māori language and cultural knowledge), tribal and whanau (extended family) links, cultural values and religion, whanau engagement and recreational activities, health status, healthy eating and discrimination. The Te Whare Tapa Wha model of health and the Poutama model of human development are utilised to provide an overall framework and context to present the results in respect of our participants and to celebrate their 'advanced' old age. The feasibility study has been successful in engagement with older Māori. It has paved the way to implement a subsequent longitudinal study which aims to enrol 600 Māori aged 80 to 90 years and 600 non-Māori aged 85 years in the Bay of Plenty and Lakes District Health Board areas (Tauranga, Rotorua, Whakatane, Opotiki and Te Kaha). The longitudinal study, "Life and Living in Advanced Age, the cohort study in New Zealand LILACS NZ - Te Puawaitanga o Nga Tapuwae Kia Ora Tonu", will record and observe participants' journeys to the end of their life. The LILACS Study NZ is at the stage of recruitment of participants and funding has been allocated for waves two and three and the next stage of the study will have an increased focus on dementia.

Despite the growing body of research on complex lifestyle behaviors (eg, Dietary Intake [DI] and Physical Activity [PA]), monitoring of these behaviors has been hampered by a lack of suitable methods. A possible solution to this deficiency is mobile-based Ecological Momentary Assessment (mEMA), which enables researchers to collect data on participants' states in real-time by means of a smartphone application. However, feasibility, usability, and ecological validity need to be anticipated and managed in order to enhance the validity of mEMA. To examine the feasibility, usability, and ecological validity of a mEMA application (app) with regard to DI and PA among Dutch vocational education students. The students (n=30) participated in the mEMA study for seven consecutive days. They downloaded the mEMA app on their smartphone. Feasibility and usability of the mEMA app were evaluated by completing an online evaluation after seven days of participation. Ecological validity was measured by assessing the degree to which the content of the mEMA app approximated the real-world setting that was being examined, through several multiple-choice questions. Compliance rates, as registered by the mEMA app, declined 46% over a seven-day period, while self-reported compliance, as measured with an online evaluation questionnaire afterwards, indicated a smaller decrease in compliance (29%). The students evaluated the mEMA app as feasible and usable. Ecological validity analyses showed that all DI and almost all PA multiple-choice options were covered with the compound response categories. The mEMA app offers the opportunity to assess complex health behaviors (eg, DI and PA) in real-time settings, in which specifically routinized behaviors are involved. However, the mEMA app faced several challenges that needed to be overcome in order to improve its validity. Overall, the present study showed that the mEMA app is a usable and ecologically valid tool to measure DI and PA behaviors among vocational education students, but compliance is still limited.

We report on a study to assess the feasibility of a swept source-based speckle variance optical coherence tomography setup for monitoring cutaneous microvasculature. Punch wounds created in the ear pinnae of diabetic mice were monitored at different times post wounding to assess the structural and vascular changes. It was observed that the epithelium thickness increases post wounding and continues to be thick even after healing. Also, the wound size assessed by vascular images is larger than the physical wound size. The results show that the developed speckle variance optical coherence tomography system can be used to monitor vascular regeneration during wound healing in diabetic mice.

2018-01-01

Background Knee osteoarthritis (OA) patients often suffer joint pain and stiffness, which contributes to negative changes in body composition, strength, physical performance (function), physical activity and health-related quality of life. To reduce these symptoms and side effects of knee OA, moderate-intensity continuous training (MICT) cycling is often recommended. While resistance training is considered the optimal form of training to improve sarcopenic outcomes, it imposes higher joint loads and requires supervision, either initially or continuously by trained exercise professionals. Therefore, this pilot study sought to gain some insight into the feasibility and potential benefits of high-intensity interval training (HIIT) cycling as an alternative exercise option to MICT cycling for individuals with knee OA. Methods Twenty-seven middle-aged and older adults with knee OA were randomly allocated to either MICT or HIIT, with both programs involving four unsupervised home-based cycling sessions (∼25 min per session) each week for eight weeks. Feasibility was assessed by enrolment rate, withdrawal rate, exercise adherence and number of adverse effects. Efficacy was assessed by health-related quality of life (Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Lequesne index), physical function (Timed Up and Go (TUG), Sit to Stand (STS) and preferred gait speed) and body composition (body mass, BMI, body fat percentage and muscle mass). Results Twenty-seven of the interested 50 potential participants (54%) enrolled in the study, with 17 of the 27 participants completing the trial (withdrawal rate of 37%); with the primary withdrawal reasons being unrelated injuries or illness or family related issues. Of the 17 participants who completed the trial, exercise adherence was very high (HIIT 94%; MICT 88%). While only three individuals (one in the MICT and two in the HIIT group) reported adverse events, a total of 28 adverse events were reported, with 24 of these attributed to one HIIT participant. Pre–post-test analyses indicated both groups significantly improved their WOMAC scores, with the HIIT group also significantly improving in the TUG and STS. The only significant between-group difference was observed in the TUG, whereby the HIIT group improved significantly more than the MICT group. No significant changes were observed in the Lequesne index, gait speed or body composition for either group. Discussion An unsupervised home-based HIIT cycle program appears somewhat feasible for middle-aged and older adults with knee OA and may produce similar improvements in health-related quality of life but greater improvements in physical function than MICT. These results need to be confirmed in larger randomised controlled trials to better elucidate the potential for HIIT to improve outcomes for those with knee OA. Additional research needs to identify and modify the potential barriers affecting the initiation and adherence to home-based HIIT cycling exercise programs by individuals with knee OA. PMID:29761054

Research indicates that promoting time spent in the outdoors and outdoor physical activity increases children's daily physical activity and improves health. One method showing promise is doctor prescriptions for outdoor physical activity for children; however, no empirical evidence currently exists on prescriptions for children's outdoor physical activity. A pilot study was conducted at one pediatric practice in western North Carolina during 2015 to test the feasibility and potential effectiveness of conducting an outdoor physical activity prescription program for children aged 5-13 years. Three pediatricians wrote prescriptions for children ( n  = 38), discussed benefits of outdoor physical activity, and provided information packets to parents on nearby places for physical activity. Parents of patients of five pediatricians served as control ( n  = 32). Prior to seeing a pediatrician, parents completed a baseline survey that asked height and weight, assessed their views of children's physical activity, and their personal and child's physical activity/sedentary behaviors. A nurse measured children's height and weight. Parents were emailed one-month and three-month follow-up surveys that asked the questions listed above. Changes in children's physical activity, outdoor physical activity, time spent in the outdoors, and sedentary activities were not significant between intervention and control groups. About half of parents (49%) viewed prescriptions as beneficial for their children and most used the intervention materials at home (70%). A larger study is needed to assess whether prescriptions increase children's physical activity. A critical examination of the intervention, pilot study design, and suggestions for a larger future study are provided.

The reported lower physical activity (PA) levels of British South Asians (SA) are suggested as a key influence in their increased risk of non-communicable diseases compared to their White British peers. Differences in objectively measured PA and sedentary behaviour (SB) between these ethnic groups have been observed during childhood (ages: 8-10 years). However, no information exists on objectively measured PA/SB in younger children, or how early in life differences in these behaviours emerge. Assessing PA/SB in the Born in Bradford (BIB) cohort study provides an opportunity to address such gaps in the literature, but previous studies have found recruiting and retaining SA participants challenging, and the feasibility of using accelerometers with SA children and parents is unknown. This study investigated the feasibility of recruiting and objectively measuring the habitual PA/SB of 2-3 year old SA and White British children and parents from the BIB study. Families were informed about the study during routine BIB assessments. Consenting families were visited at home for anthropometry measurements, interviews, material delivery and collection. Participants (child and parents) were instructed to wear the ActiGraph GT3X+ for 8 days. Descriptive statistics were computed, and ethnic differences tested (Chi-square) for recruitment uptake and compliance. 160 families (30 % SA) provided contact details, and 97 (22 % SA) agreed to enter the study. White British families showed lower refusal and higher intake into the study than SA (p = 0.006). Of 89 children issued with an accelerometer, 34 % complied with the 8-day protocol (significantly less SA; p = 0.015) and 75 % provided enough days (≥ 3) to assess habitual PA/SB (no ethnic differences). Parental rates of compliance with the protocol did not differ between ethnicities. Issues experienced with the protocol and accelerometer use, and successful implementation strategies/procedures are presented. Although greater efforts may be required to recruit SA, those consenting to participate were as likely as White British to provide enough data to assess habitual PA/SB. The issues and successful strategies reported in this feasibility study represent valuable information for planning future studies, and enhance recruitment and compliance with accelerometer protocols in SA and White British toddlers and parents.

There are no biological treatments for fetal alcohol spectrum disorders (FASDs), lifelong conditions associated with physical anomalies, brain damage, and neurocognitive abnormalities. In preclinical studies, choline partially ameliorates memory and learning deficits from prenatal alcohol exposure. This phase I pilot study evaluated the feasibility, tolerability, and potential adverse effects of choline supplementation in children with FASD. We hypothesized that choline would be well tolerated with minimal adverse events. The study design was a double-blind, randomized, placebo-controlled trial. Participants included 20 children aged 2.5 to 4.9 years with prenatal alcohol exposure and FASD diagnoses. Participants were randomly assigned to 500 mg choline or placebo daily for 9 months (10 active, 10 placebo). Primary outcome measures included feasibility, tolerability, adverse effects, and serum choline levels. Seventeen participants completed the study. Compliance was 82% to 87%, as evidenced by parent-completed log sheets and dose counts. Periodic 24-hour dietary recalls showed no evidence of dietary confounding. Adverse events were minimal and were equivalent in the active and placebo arms with the exception of fishy body odor, which occurred only in the active group. There were no serious adverse events to research participants. This phase I pilot study demonstrates that choline supplementation at 500 mg/d for 9 months in children aged 2 to 5 years is feasible and has high tolerability. Further examination of the efficacy of choline supplementation in FASD is currently underway. © 2013.

King, Bruce J.

2000-08-01

A review is given of the prospects for future colliders and collider physics at the energy frontier. A proof-of-plausibility scenario is presented for maximizing our progress in elementary particle physics by extending the energy reach of hadron and lepton colliders as quickly and economically as might be technically and financially feasible. The scenario comprises 5 colliders beyond the LHC—one each of e+e- and hadron colliders and three μ+μ- colliders — and is able to hold to the historical rate of progress in the log-energy reach of hadron and lepton colliders, reaching the 1 PeV constituent mass scale by the early 2040's. The technical and fiscal requirements for the feasibility of the scenario are assessed and relevant long-term R&D projects are identified. Considerations of both cost and logistics seem to strongly favor housing most or all of the colliders in the scenario in a new world high energy physics laboratory.

With improving survival rates following HSCT in children, QOL and management of short- and long-term effects need to be considered. Exercise may help mitigate fatigue and declines in fitness and strength. The aims of this study were to assess the feasibility of an inpatient exercise intervention for children undergoing HSCT and observe the changes in physical and psychological health. Fourteen patients were recruited, mean age 10 yr. A 6MWT, isometric upper and lower body strength, balance, fatigue, and QOL were assessed prior to Tx and six wk post-Tx. A supervised exercise program was offered five days per week during the inpatient period and feasibility assessed through uptake rate. The study had 100% program completion and 60% uptake rate of exercise sessions. The mean (± s.d.) weekly activity was 117.5 (± 79.3) minutes. Younger children performed significantly more minutes of exercise than adolescents. At reassessment, strength and fatigue were stabilized while aerobic fitness and balance decreased. QOL revealed a non-statistical trend towards improvement. No exercise-related adverse events were reported. A supervised inpatient exercise program is safe and feasible, with potential physiological and psychosocial benefits. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

This study documented the feasibility and immediate effects of a dance intervention two times per week for 12 weeks on depression, physical function, and disability in older, underserved adults. The one-group, pretest-posttest study had a convenience sample of 40 participants recruited from a federally subsidized apartment complex located in an economically depressed, inner-city neighborhood. Depression, physical function, and disability were measured at baseline and 12 weeks. Average age was 63 years (SD = 7.9), 92% were female, and 75% were African American. At baseline, participants reported increased depression (M = 20.0, SD = 12.4), decreased physical function (M = 56.6, SD = 10.9), and increased disability limitations (M = 65.7, SD = 14.9). At posttest, paired t tests showed that the dance intervention significantly decreased depression, t = 6.11, p < .001, and disability, t = -2.70, p = .014, and significantly increased physical function, t = -2.74, p = .013. The results indicate that the 12-week dance intervention may be an effective adjunct therapy to improve depression, disability, and physical function in underserved adults.

The entry-level physical therapist: a case for COMFORT communication training.

2015-01-01

Entry-level physical therapists provide clinical care for patients with functional mobility limitations. Their care spans the continuum of settings, disease processes, and diagnoses. Although effective communication skills are required to conduct physical therapy work, there is limited instruction provided in physical therapy education and students receive little exposure to seriously or chronically ill patients. The goal of this study was to assess the effects of communication training for the entry-level physical therapist facing palliative and end-of-life communication with patients/families. A pre-post survey design and narrative writing were used to assess the effect of the COMFORT communication training curriculum provided to doctorally trained, graduating physical therapists. The study demonstrated decreased student apprehension about communicating with dying patients and their families, and a comparison of mean scores reflecting the students' communication knowledge, confidence, and behaviors increased in a positive direction. As students became more willing to communicate, they were also more adept at integrating task and relational messages, as well as assimilating emotional support messages for patients and families. This study shows promise for the feasibility and utilization of the COMFORT curriculum for entry-level physical therapists. Further research should address the integration of COMFORT earlier into physical therapy education, as well as assess evidence of COMFORT communication skills in the clinical context.

2018-02-01

Present study makes a punctilious investigation of the profiles of Stark shift (SS) of doped GaAs quantum dot (QD) under the supervision of Gaussian white noise. A few physical parameters have been varied and the consequent variations in the SS profiles have been monitored. The said physical parameters comprise of magnetic field, confinement potential, dopant location, dopant potential, noise strength, aluminium concentration (only for AlxGa1-x As alloy QD), position-dependent effective mass (PDEM), position-dependent dielectric screening function (PDDSF), anisotropy, hydrostatic pressure (HP) and temperature. The SS profiles unfurl interesting features that heavily depend upon the particular physical quantity concerned, presence/absence of noise and the manner (additive/multiplicative) noise enters the system. The study highlights feasible means of maximizing SS of doped QD in presence of noise by suitable adjustment of several control parameters. The study deems importance in view of technological applications of QD devices where noise plays some prominent role.

To pilot, among women with gestational diabetes mellitus (GDM), the feasibility of a prenatal/postpartum intervention to modify diet and physical activity similar to the Diabetes Prevention Program. The intervention was delivered by telephone, and support for breastfeeding was addressed. The goal was to help women return to their prepregnancy weight, if it was normal, or achieve a 5% reduction from prepregnancy weight if overweight. Eligible participants were identified shortly after a GDM diagnosis; 83.8% consented to be randomly assigned to intervention or usual medical care (96 and 101 women, respectively). The retention was 85.2% at 12 months postpartum. The proportion of women who reached the postpartum weight goal was higher, although not statistically significant, in the intervention condition than among usual care (37.5 vs. 21.4%, absolute difference 16.1%, P=0.07). The intervention was more effective among women who did not exceed the recommended gestational weight gain (difference in the proportion of women meeting the weight goals: 22.5%, P=0.04). The intervention condition decreased dietary fat intake more than the usual care (condition difference in the mean change in percent of calories from fat: -3.6%, P=0.002) and increased breastfeeding, although not significantly (condition difference in proportion: 15.0%, P=0.09). No differences in postpartum physical activity were observed between conditions. This study suggests that a lifestyle intervention that starts during pregnancy and continues postpartum is feasible and may prevent pregnancy weight retention and help overweight women lose weight. Strategies to help postpartum women overcome barriers to increasing physical activity are needed.

Introduction This study examined feasibility of a place-based community health worker (CHW) and health advocate (HA) initiative in five public housing developments selected for high chronic disease burden and described early outcomes. Methods This intervention was informed by a mixed-method needs assessment performed December 2014–January 2015 (representative telephone survey, n=1,663; six focus groups, n=55). Evaluation design was a non-randomized, controlled quasi-experiment. Intake and 3-month follow-up data were collected February–December 2015 (follow-up response rate, 93%) on 224 intervention and 176 comparison participants, and analyzed in 2016. All participants self-reported diagnoses of hypertension, diabetes, or asthma. The intervention consisted of chronic disease self-management and goal setting through six individual CHW-led health coaching sessions, instrumental support, and facilitated access to insurance/clinical care navigation from community-based HAs. Feasibility measures included CHW service satisfaction and successful goal setting. Preliminary outcomes included clinical measures (blood pressure, BMI); disease management behaviors and self-efficacy; and preventive behaviors (physical activity). Results At the 3-month follow-up, nearly all intervention participants reported high satisfaction with their CHW (90%) and HA (76%). Intervention participants showed significant improvements in self-reported physical activity (p=0.005) and, among hypertensive participants, self-reported routine blood pressure self-monitoring (p=0.013) compared with comparison participants. No improvements were observed in self-efficacy or clinical measures at the 3-month follow-up. Conclusions Housing-based initiatives involving CHW and HA teams are acceptable to public housing residents and can be effectively implemented to achieve rapid improvements in physical activity and chronic disease self-management. At 3-month assessment, additional time and efforts are required to improve clinical outcomes. PMID:28215382

Research had been conducted to develop Multipurpose Kundt's tube as a physics learning media. Research background was the absence of sound waves visualization to improve the understanding of learners. The purposes of this research were to develop Multipurpose Kundt’s tube as physics learning media and to test its feasibility. The developed tool was tested to find the speed of sound in the air, showing the double slit interference phenomenon of the sound, and show the temperature changes in the cold and heat reservoirs in the thermoacoustic process. The development step that had been used was Preliminary Study, Development, Field Test, and Dissemination or known as PDFD Model. On the implementation, the dissemination process was not done. The test was done by the experts, peers, and college students to find out the media feasibility level. The speed of sound in the air which was measured using Multipurpose Kundt’s tube obtained v ± Δv = 263 ± 24 m/s with the closeness value of 76.63% closer to the theoretical value. Also, it was founded a calibration factor of 1.32. The tool was able to show sound waves on the open-end tube. The value of the distance between minimum and maximum interferences between the experimental results compared to theory was almost the same, so it was concluded that the phenomenon of double-slit interference of the sound could be shown by the tool. The thermoacoustic phenomenon could be observed and gave maximum temperature 31.4°C in the hot reservoir, and minimum temperature 24°C in the cold reservoir at the frequency of 119 Hz. Temperature differences obtained 7.4°C. The result of the feasibility test obtained the average result of 88.23 in a “Very Good” category.

To test the feasibility of Kids SIP smartER, a school-based intervention to reduce consumption of sugar-sweetened beverages (SSBs). Matched-contact randomized crossover study with mixed-methods analysis. One middle school in rural, Appalachian Virginia. Seventy-four sixth and seventh graders (5 classrooms) received Kids SIP smartER in random order over 2 intervention periods. Feasibility outcomes were assessed among 2 teachers. Kids SIP smartER consisted of 6 lessons grounded in the Theory of Planned Behavior, media literacy, and public health literacy and aimed to improve individual SSB behaviors and understanding of media literacy and prevalent regional disparities. The matched-contact intervention promoted physical activity. Beverage Intake Questionnaire-15 (SSB consumption), validated theory questionnaires, feasibility questionnaires (student and teacher), student focus groups, teacher interviews, and process data (eg, attendance). Repeated measures analysis of variances across 3 time points, descriptive statistics, and deductive analysis of qualitative data. During the first intervention period, students receiving Kids SIP smartER (n = 43) significantly reduced SSBs by 11 ounces/day ( P = .01) and improved media ( P < .001) and public health literacy ( P < .01) understanding; however, only media literacy showed between-group differences ( P < .01). Students and teachers found Kids SIP smartER acceptable, in-demand, practical, and implementable within existing resources. Kids SIP smartER is feasible in an underresourced, rural school setting. Results will inform further development and large-scale testing of Kids SIP smartER to reduce SSBs among rural adolescents.

Our aim was to use participatory methods to investigate the feasibility and acceptability of using Bingo clubs for the design and delivery of an evidence-based physical activity and/or healthy eating intervention to socio-economically disadvantaged women. This paper describes the participatory process that has resulted in a physical activity intervention for women aged >55 years, ready for pilot-testing in a Bingo club setting. Studies using different quantitative and qualitative approaches were conducted among customers and staff of a Bingo club in a city of 85,000 inhabitants in central Scotland. These were designed to take the views of different stakeholders into account, with a view to enhancing uptake, engagement and effectiveness with any proposed intervention. Sixteen relevant studies were identified in a literature review that generated ideas for intervention components. A questionnaire completed by 151 women in the Bingo club showed that almost half (47 %) aged >55 years were not meeting physical activity guidelines; evidence backed up by accelerometer data from 29 women. Discussions in six focus groups attended by 27 club members revealed different but overlapping motivations for attending the Bingo club (social benefits) and playing Bingo (cognitive benefits). There was some scepticism as to whether the Bingo club was an appropriate setting for an intervention, and a dietary intervention was not favoured. It was clear that any planned intervention needed to utilise the social motivation and habitual nature of attendance at the Bingo club, without taking women away from Bingo games. These results were taken forward to a 5-h long participative workshop with 27 stakeholders (including 19 Bingo players). Intervention design (form and content) was then finalised during two round table research team meetings. It was possible to access and engage with women living in areas of socio-economic disadvantage through a Bingo club setting. A physical activity intervention for women >55 years is realistic for recruitment, will address the needs of potential recipients in the Bingo club, appears to be feasible and acceptable to club members and staff, and has been designed with their input. A pilot study is underway, investigating recruitment, retention and feasibility of delivery.

The aims were to 1) determine feasibility of measuring physical function in our ICU Recovery Clinic (RC), 2) determine if physical function was associated with 6-month re-hospitalization and 1-year mortality and 3) compare ICU survivors' physical function to other comorbid populations. We established the Wake Forest ICU RC. Patients were seen in clinic 1month following hospital discharge. Testing included the Short Form-36 questionnaire and Short Physical Performance Battery (SPPB). We related these measures to 6month re-hospitalizations and 1year mortality, and compared patients' functional performance with other comorbid populations. Thirty-six patients were seen in clinic from July 2014 to June 2015; the median SPPB score was 5 (IQR 5). The median SF-36 physical component summary score was 21.8 (IQR 28.8). Mortality was 14% at 1year. Of those who did not die by 1year, 35% were readmitted to our hospital within 6months of hospital discharge. SPPB scores demonstrated a non-significant trend with both mortality (p=0.06) and readmissions (p=0.09). ICU survivors' SPPB scores were significantly lower than those of other chronically ill populations (p<0.001). Physical function measurement in a recovery clinic is feasible and may inform subsequent morbidity and mortality. Copyright © 2018 Elsevier Inc. All rights reserved.

2016-11-01

Lattice hydrodynamic model is a typical continuum traffic flow model, which describes the jamming transition of traffic flow properly. Previous studies in lattice hydrodynamic model have shown that the use of control method has the potential to improve traffic conditions. In this paper, a new control method is applied in lattice hydrodynamic model from a transportation cyber-physical system approach, in which only one lattice site needs to be controlled in this control scheme. The simulation verifies the feasibility and validity of this method, which can ensure the efficient and smooth operation of the traffic flow.

Background Skin cancer is the most prevalent cancer in Australia. Skin cancer prevention programs aim to reduce sun exposure and increase sun protection behaviors. Effectiveness is usually assessed through self-report. Objective It was the aim of this study to test the acceptance and validity of a newly developed ultraviolet radiation (UVR) exposure app, designed to reduce the data collection burden to research participants. Physical activity data was collected because a strong focus on sun avoidance may result in unhealthy reductions in physical activity. This paper provides lessons learned from collecting data from participants using paper diaries, a mobile app, dosimeters, and accelerometers for measuring end-points of UVR exposure and physical activity. Methods Two participant groups were recruited through social and traditional media campaigns 1) Group A—UVR Diaries and 2) Group B—Physical Activity. In Group A, nineteen participants wore an UVR dosimeter wristwatch (University of Canterbury, New Zealand) when outside for 7 days. They also recorded their sun exposure and physical activity levels using both 1) the UVR diary app and 2) a paper UVR diary. In Group B, 55 participants wore an accelerometer (Actigraph, Pensacola, FL, USA) for 14 days and completed the UVR diary app. Data from the UVR diary app were compared with UVR dosimeter wristwatch, accelerometer, and paper UVR diary data. Cohen kappa coefficient score was used to determine if there was agreement between categorical variables for different UVR data collection methods and Spearman rank correlation coefficient was used to determine agreement between continuous accelerometer data and app-collected self-report physical activity. Results The mean age of participants in Groups A (n=19) and B (n=55) was 29.3 and 25.4 years, and 63% (12/19) and 75% (41/55) were females, respectively. Self-reported sun exposure data in the UVR app correlated highly with UVR dosimetry (κ=0.83, 95% CI 0.64-1.00, P<.001). Correlation between self-reported UVR app and accelerometer-collected moderate to vigorous physical activity data was low (ρ=0.23, P=.10), while agreement for low-intensity physical activity was significantly different (ρ=-0.49, P<.001). Seventy-nine percent of participants preferred the app over the paper diary for daily self-report of UVR exposure and physical activity. Conclusions This feasibility study highlights self-report using an UVR app can reliably collect personal UVR exposure, but further improvements are required before the app can also be used to collect physical activity data.

Explore the feasibility of a Tai Chi intervention to improve musculoskeletal pain, emotion, cognition, and physical function in individuals with posttraumatic stress disorder. Two-phase, one-arm quasi-experimental design. Phase 1: 11 participants completed one Tai Chi session, feasibility questionnaire, and were offered participation in Phase 2, a 12-week Tai Chi intervention. Ten participants participated in Phase 2. Pain intensity, interference, physical function scales, an emotional battery, and cognition tests were used for pre- and postintervention outcome measures. Paired t tests and thematic analysis were used for analysis. In Phase 1, most felt Tai Chi would benefit health (90.9%) and expressed interest in continuing Tai Chi (6.73 out of 7). Phase 2 results showed improvement in fear-affect (raw t = -2.64, p = .03; age adjusted t = -2.90, p = .02), fear-somatic arousal (raw t = -2.53, p = .035), List Sorting Working Memory (raw t = 2.62, p = .031; age adjusted t = 2.96, p = .018), 6-Minute Walk Test ( t = 3.541, p = .008), and current level of Pain Intensity ( t = -4.00, p = .004). Tai Chi is an acceptable, holistic treatment to individuals with musculoskeletal pain and posttraumatic stress disorder. It may reduce pain, improve emotion, memory, and physical function.

Regular physical activity (PA) benefits older adults. However, frail older adults lack opportunities to be physically active. This pilot study aimed to test and enhance the feasibility of a PA program delivered by home care aides (HCAs) for community-dwelling older adults in a Medicaid-funded home care setting and to generate preliminary efficacy and cost data. HCAs were trained to deliver a brief motivational enhancement and three chair-bound movements to motivate their older clients to do PA daily and to help maintain their independence in the community. Mixed methods were used to evaluate clients' function and health before and after the 4-month intervention. Clients' daily activity function and health outcomes (physical fitness, self-rated health, pain interference, and fear of falling) improved significantly. The program was well-received by clients (N = 54) and their HCAs (N = 46) as indicated by high retention rates among client participants (93%) and remarks provided by clients. Building PA into the everyday care of older adults and the routine work of HCAs is feasible. The intervention has the potential for further implementation and dissemination. © The Author 2017.

Low-income Latinas (Hispanics) face risk for cardiovascular disease due to high rates of overweight/obesity, sedentary lifestyle, and other factors. Limited access to health care and language barriers may prevent delivery of health promotion messages. Targeted approaches, including the integration of community health workers, may be required to promote healthy lifestyle and prevent chronic disease in underserved ethnic minority groups. The term commonly used to refer to female community health workers in Latino communities is "promotora(s)." This study evaluates the outcomes and feasibility of a promotora-led lifestyle behavior intervention for overweight, immigrant Latinas. A community prevention model was employed in planning and implementing this study. A randomized controlled trial design was used. A Community Advisory Board provided expertise in evaluating feasibility of study implementation in the community and other important guidance. The sample was comprised of 223 women aged 35-64 years, predominantly with low income and ≤8th grade education. The culturally tailored Lifestyle Behavior Intervention included group education (8 classes based upon Su Corazon, Su Vida), followed by 4 months of individual teaching and coaching (home visits and telephone calls). The control group received a comparable length educational program and follow-up contacts. Evaluations were conducted at baseline and at 6 and 9 months using a dietary habits questionnaire, accelerometer readings of physical activity, and clinical measures (body mass index, weight, waist circumference, blood pressure, lipids, blood glucose). Data were collected between January 2010 and August 2012. Women in the intervention group improved significantly in dietary habits, waist circumference, and physical activity in comparison to those in the control group. A treatment dosage effect was observed for weight and waist circumference. Knowledge about heart disease increased. High attendance at classes and participation in the individual teaching and counseling sessions and high retention rates support the feasibility and acceptability of the promotora-led lifestyle behavior intervention. Our findings demonstrate that lifestyle behaviors and other risk factors of overweight Latina women may be improved through a promotora-led lifestyle behavior intervention. Feasibility of implementing this intervention in community settings and engaging promotoras as facilitators is supported. Copyright © 2014 Elsevier Ltd. All rights reserved.

Body composition measurements provide important information about physical fitness and nutritional status. People with severe intellectual and visual disabilities (SIVD) have an increased risk for altered body composition. Bioelectrical impedance analysis (BIA) has been evidenced as a reliable and non-invasive method to asses body composition in healthy persons and various patient populations; however, currently, there is no feasible method available to determine body composition in people with SIVD. In this study, therefore, we aimed to assess the feasibility of BIA measurements in persons with SIVD. In 33 participants with SIVD and Gross Motor Functioning Classification System (GMFCS) Scale I, II, III, or IV, two BIA measurements were sequentially performed employing Resistance and Reactance in Ohm and fat-free mass (FFM) in kg as outcome variables, utilizing the Bodystat(®) QuadScan 4000. Feasibility was considered sufficient if ≥ 80% of the first measurement was performed successfully. Agreement between two repeated measurements was determined by using the paired t-test and Intraclass Correlation Coefficient (ICC; two way random, absolute agreement). Bland-Altman analyses were utilized to determine limits of agreement (LOAs) and systematic error. Agreement was considered acceptable if LOAs were <10% of the mean of the first measurement. The first BIA measurements were completed successfully in 88% of the participants. The paired t-test demonstrated no significant differences in Resistance, Reactance, and FFM between BIA Measurements 1 and 2 (P=0.140, 0.091, and 0.866). ICC was 0.965 (95% CI: 0.922-0.984) for Resistance; 0.858 (95% CI: 0.705-0.934) for Reactance; and 0.992 (95% CI: 0.982-0.996) for FFM. LOAs expressed as a percentage of the mean of Measurement 1 were 6.1% for Resistance, 17.6% for Reactance, and 3.8% for FFM. The results of this study suggest that BIA measurements seem to be feasible in persons with SIVD. Although these results require confirmation in a more extensive sample of persons with SIVD, the findings of this study are an important first step in the assessment of applicability of BIA measurements for non-invasive monitoring of physical fitness and nutritional status of persons with SIVD.

Introduction After a diagnosis of localised breast cancer, overweight, obesity and weight gain are negatively associated with prognosis. In contrast, maintaining an optimal weight through a balanced diet combined with regular physical activity appears to be effective protective behaviour against comorbidity or mortality after a breast cancer diagnosis. The primary aim of the Programme pour une Alimentation Saine et une Activité Physique Adaptée pour les patientes atteintes d'un cancer du Sein (PASAPAS) randomised controlled trial is to evaluate the feasibility of implementing an intervention of adapted physical activity (APA) for 6 months concomitant with the prescription of a first line of adjuvant chemotherapy. Secondary aims include assessing the acceptability of the intervention, compliance to the programme, process implementation, patients’ satisfaction, evolution of biological parameters and the medicoeconomic impact of the intervention. Methods and analysis The study population consists of 60 women eligible for adjuvant chemotherapy after a diagnosis of localised invasive breast cancer. They will be recruited during a 2-year inclusion period and randomly allocated between an APA intervention arm and a control arm following a 2:1 ratio. All participants should benefit from personalised dietetic counselling and patients allocated to the intervention arm will be offered an APA programme of two to three weekly sessions of Nordic walking and aerobic fitness. During the 6-month intervention and 6-month follow-up, four assessments will be performed including blood draw, anthropometrics and body composition measurements, and questionnaires about physical activity level, diet, lifestyle factors, psychological criteria, satisfaction with the intervention and medical data. Ethics and dissemination The study was approved by the French Ethics Committee (Comité de Protection des Personnes Sud-Est IV) and the national agencies for biomedical studies and for privacy. All participants will give written informed consent. The study findings will be disseminated through the scientific public and serve as a foundation for future randomised controlled trials of efficacy. PMID:24165030

2014-11-01

This study aimed at investigating whether providing feedback on physical activity (PA) levels to patients with chronic obstructive pulmonary disease (COPD) is feasible and enhances daily PA during pulmonary rehabilitation (PR). Patients with COPD participated in a 12-week PR program. Daily PA was measured using activity monitors on weeks 1, 7, and 12, and feedback was given in the following weeks on the number of steps, time spent in sedentary, light, and moderate-to-vigorous intensity activities, and time spent standing, sitting, and lying. Compliance with PA monitoring was collected. Two focus groups were conducted to obtain patients' perspectives on the use of activity monitors and on the feedback given. Differences in PA data were also assessed. Sixteen patients (65.63 ± 10.57 years; forced expiratory volume in one second (FEV1) 70.31 ± 22.74% predicted) completed the study. From those, only eleven participants used the activity monitors during all monitoring days. Participants identified several problems regarding the use of activity monitors and monitoring duration. Daily steps (p = 0.026) and standing time (p = 0.030) were improved from week 1 to week 7; however, the former declined from week 7 to week 12. Findings suggest that using feedback to improve PA during PR is feasible and results in improved daily steps and standing time on week 7. The subsequent decline suggests that additional strategies may be needed to stimulate/maintain PA improvements. Further research with more robust designs is needed to investigate the impact of feedback on patients' daily PA. © The Author(s) 2014.

Various bio-sheet grafts have been attempted either to accelerate healing of artificial ulcers or to prevent adverse events after endoscopic submucosal dissection (ESD), but neither prospective nor mechanistic studies were available. To evaluate the substantial effect of a bio-sheet graft on artificial ulcer healing and its feasibility as an endoscopic treatment modality. Preclinical, in vivo animal experiment and proof-of-concept study. Animal laboratory. Three mini-pigs, Sus scrofa, mean age 14 months. Multiple ulcers sized 2.5 cm in diameter were generated by ESD in 3 mini-pigs and were assigned randomly into the following 3 groups; control group, bio-sheet group, or combination (bio-sheet plus drug) group. Bio-sheet grafts or bio-sheet plus drug combinations were applied on the artificial ulcers immediately after the ESD. Feasibility and efficacy of endoscopic bio-sheet graft therapy for the management of artificial ulcers and the evaluation of healing conditions based on histology changes in the remaining gastric bed tissues harvested from the stomachs. Thirty-three ESD specimens were obtained. On an image analysis of the ratio of healed area in the remaining gastric bed tissue compared with the matched dissected gastric mucosa, the control group showed the most significant improvement in healing activity among the 3 groups (P < .05), whereas the severity of inflammation in the remaining ulcer tissue was significantly attenuated in bio-sheet and combination groups (P < .05). Animal model. Although the bio-sheet grafts provided physical protection from gastric acid attack as reflected in the attenuated inflammation on the ulcer beds, unexpected delayed ulcer healing was noted in the bio-sheet graft group because of its physical hindrance of the healing process.

Physical activity (PA) may be important for preventing chronic diseases for adolescent and young adult (AYA) childhood cancer survivors. Randomized controlled trials (RCTs) of PA interventions for AYA survivors are sparse, but necessary to determine effective programs for increasing PA among this population. Thus, we conducted a pilot RCT, testing the feasibility of a mobile health (mHealth) intervention to promote PA among AYA survivors. We recruited 14- to 18-year-olds who were ≥1-year post cancer therapy from Seattle Children's Hospital. The 10-week intervention consisted of a wearable PA-tracking device (Fitbit Flex) and a peer-based virtual support group (Facebook group). Research staff helped set step goals and awarded badges weekly. Controls received usual care. Baseline assessments occurred before randomization and follow-up assessments occurred during weeks 8-10 of the intervention period. Feasibility criteria are defined below. Qualitative interviews assessed acceptability. Exploratory outcomes included PA, quality of life, and motivation for PA. All feasibility criteria were met: we recruited 60 survivors, intervention participants wore the Fitbit on the majority (71.5%) of intervention days, and ≥90% of all participants completed questionnaires. Qualitative data confirmed intervention acceptability. Exploratory analyses found no significant adjusted group differences for change in moderate-to-vigorous PA (4.4 vs. 5.0 min/day; P = 0.92) or sedentary time (-4.5 vs. 1.0 min/day; P = 0.73), comparing intervention subjects to controls. Some modest differences were found for select subscales of quality of life and motivation for PA. This mHealth PA intervention was feasible and acceptable to AYA childhood cancer survivors and warrants a fully powered RCT. © 2017 Wiley Periodicals, Inc.

Stimulation of a physically active lifestyle among older adults is essential to health and well-being. The objective of this study was to evaluate the feasibility and user opinion of a home-based exercise program supported by a sensor and tablet application for frail older adults. Community-dwelling older adults (aged ≥70 y) living in The Netherlands were recruited in 2014. Participants exercised 3 months with and 3 months without supervision from a remote coach. Feasibility was operationalized as adherence to exercise (percentage of 5 exercise bouts per week completed) and to wearing the sensor (with 70% defined as sufficient adherence) and the number of problems reported. User opinion was measured with a questionnaire addressing ease of use of the technology and opinion on the program. Twenty-one of 40 enrolled participants completed the trial. Adherence overall was 60.9% (average of 3 bouts per week). Adherence among completers (69.2%) was significantly higher than adherence among dropouts (49.9%). Adherence was sufficient among completers during the 3 months of supervision (75.8%). Adherence to wearing the sensor was 66.7% and was significantly higher among completers than among dropouts (75.7% vs 54.2%). The rate of incidents was significantly lower among completers than among dropouts (0.4 vs 1.2 incidents per participant per week). Connectivity-related incidents were prominent. On a scale of 1 to 5, completers gave ratings of 4.3 (after 3 months) and 4.2 (after 6 months). A home-based exercise program using novel technology seems feasible when participants are given a stable internet connection. This program shows promise for stimulating physical activity among older frail adults, especially if it offers regular coaching.

Physical exercises offer a variety of health benefits to cancer survivors during and post-treatment. However, exercise-based pre-habilitation is not well reported in major uro-oncology surgery. The aim of this study was to investigate the feasibility, the adherence, and the efficacy of a short-term physical pre-habilitation program to patients with invasive bladder cancer awaiting radical cystectomy (RC). A parent prospective randomized controlled clinical trial investigated efficacy of a multidisciplinary rehabilitation program on length of stay following RC. A total of 107 patients were included in the intension-to-treat population revealing 50 patients in the intervention group and 57 patients in the standard group. Pre-operatively, the intervention group was instructed to a standardized exercise program consisting of both muscle strength exercises and endurance training. The number of training sessions and exercise repetitions was patient-reported. Feasibility was expressed as adherence to the program and efficacy as the differences in muscle power within and between treatment groups at time for surgery. A total of 66 % (95 % confidence interval (CI) 51; 78) adhered more than 75 % of the recommended progressive standardized exercise program. In the intervention group, a significant improvement in muscle power of 18 % (p < 0.002) was found at time for surgery. Moreover, muscle power was significantly improved compared to that in the standard group with 0.3 W/kg (95 % CI 0.08; 0.5 %) (p < 0.006). Adherence was not associated with pre-operative BMI, nutritional risk, comorbidity, pain, gender, or age. In patients awaiting RC, a short-term exercise-based pre-habilitation intervention is feasible and effective and should be considered in future survivorship strategies.

This research aimed to investigate feasibility of outlet water of water treatment plant and limewater on properties of Portland pozzolana cement (PPC). Twenty water treatment plants were found out in the Bhimavaram municipality region in West Godavari district, Andhra Pradesh, India. Approximately, each plant supplying potable water about 4000 to 5000 L/day. All plants are extracting ground water and treating through Reverse Osmosis (RO) process. At outlet, huge quantity of wasted water is being discharged into side drains in Bhimavaram municipality. One typical treatment plant was selected, and water at outlet was collected and Physical and chemical analysis was carried out as per producer described in APHA. The effect of plant outlet water(POW), lime water(LM), and plant outlet water with lime (POWL) on physical properties i.e., setting times, compressive strength, and flexural strength of Portland pozzolana Cement (PPC) were studied in laboratory and compared same with reference specimens i.e., made with Distilled Water (DW) as mixing water. No significant change was observed in initial and finial setting time in POW, LW, and (POWL) as compared with reference specimens made with distilled water (DW). Compressive strength was significantly increased with LW and (POWL) specimens compared to that of reference specimens. XRD technique was employed to study the mineralogical analysis.

Diabetes technology has the potential to provide useful data for theory-based behavioral counseling. The aims of this study are to evaluate the feasibility, acceptability, and preliminary efficacy of a continuous glucose monitoring and problem-solving counseling intervention to change physical activity (PA) behavior in women with type 2 diabetes. Women (n=29) with type 2 diabetes were randomly assigned to one of two treatment conditions: continuous glucose counseling and problem-solving skills or continuous glucose monitoring counseling and general diabetes education. Feasibility data were obtained on intervention dose, implementation, and satisfaction. Preliminary efficacy data were collected at baseline and 12 weeks on the following measures: PA amount and intensity, diet, problem-solving skills, self-efficacy for PA, depression, hemogoloin A1c, weight, and blood pressure. Demographic and implementation variables were described using frequency distributions and summary statistics. Satisfaction data were analyzed using Wilcoxon rank. Differences between groups were analyzed using linear mixed-modeling. Women were mostly white/non-Latina with a mean age of 53 years, a 6.5-year history of diabetes, and suboptimal glycemic control. Continuous glucose monitoring plus problem-solving group participants had significantly greater problem-solving skills and had greater, although not statistically significant, dietary adherence, moderate activity minutes, weight loss, and higher intervention satisfaction pre- to post-intervention than did participants in the continuous glucose monitoring plus education group. A continuous glucose monitoring plus problem-solving intervention was feasible and acceptable, and participants had greater problem-solving skills than continuous glucose monitoring plus education group participants.

During the past several years, a considerable amount of work has been carried out showing that microbially enhanced oil recovery (MEOR) is promising and the resulting biotechnology may be deliverable. At Brookhaven National Laboratory (BNL), systematic studies have been conducted which dealt with the effects of thermophilic and thermoadapted bacteria on the chemical and physical properties of selected types of crude oils at elevated temperatures and pressures. Current studies indicate that during the biotreatment several chemical and physical properties of crude oils are affected. The oils are (1) emulsified; (2) acidified; (3) there is a qualitative and quantitative change inmore » light and heavy fractions of the crudes; (4) there are chemical changes in fractions containing sulfur compounds; (5) there is an apparent reduction in the concentration of trace metals; and (6) the qualitative and quantitative changes appear to be microbial species dependent; and (7) there is a distinction between biodegraded and biotreated oils. The downstream biotechnological crude oil processing research performed thus far is of laboratory scale and has focused on demonstrating the technical feasibility of downstream processing with different types of biocatalysts under a variety of processing conditions. Quantitative economic analysis is the topic of the present project which investigates the economic feasibility of the various biochemical downstream processes which hold promise in upgrading of heavy crudes, such as those found in California, e.g., Monterey-type, Midway Sunset, Honda crudes, and others.« less

Assessing physical activity using wearable monitors: measures of physical activity.

PubMed

Butte, Nancy F; Ekelund, Ulf; Westerterp, Klaas R

2012-01-01

Physical activity may be defined broadly as "all bodily actions produced by the contraction of skeletal muscle that increase energy expenditure above basal level." Physical activity is a complex construct that can be classified into major categories qualitatively, quantitatively, or contextually. The quantitative assessment of physical activity using wearable monitors is grounded in the measurement of energy expenditure. Six main categories of wearable monitors are currently available to investigators: pedometers, load transducers/foot-contact monitors, accelerometers, HR monitors, combined accelerometer and HR monitors, and multiple sensor systems. Currently available monitors are capable of measuring total physical activity as well as components of physical activity that play important roles in human health. The selection of wearable monitors for measuring physical activity will depend on the physical activity component of interest, study objectives, characteristics of the target population, and study feasibility in terms of cost and logistics. Future development of sensors and analytical techniques for assessing physical activity should focus on the dynamic ranges of sensors, comparability for sensor output across manufacturers, and the application of advanced modeling techniques to predict energy expenditure and classify physical activities. New approaches for qualitatively classifying physical activity should be validated using direct observation or recording. New sensors and methods for quantitatively assessing physical activity should be validated in laboratory and free-living populations using criterion methods of calorimetry or doubly labeled water.

2014-01-01

Self-determination theory and self-efficacy theory are prominent theories in the physical activity literature, and studies have begun integrating their concepts. Sweet, Fortier, Strachan and Blanchard (2012) have integrated these two theories in a cross-sectional study. Therefore, this study sought to test a longitudinal integrated model to predict physical activity at the end of a 4-month cardiac rehabilitation program based on theory, research and Sweet et al.’s cross-sectional model. Participants from two cardiac rehabilitation programs (N=109) answered validated self-report questionnaires at baseline, two and four months. Data were analyzed using Amos to assess the path analysis and model fit. Prior to integration, perceived competence and self-efficacy were combined, and labeled as confidence. After controlling for 2-month physical activity and cardiac rehabilitation site, no motivational variables significantly predicted residual change in 4-month physical activity. Although confidence at two months did not predict residual change in 4-month physical activity, it had a strong positive relationship with 2-month physical activity (β=0.30, P<0.001). The overall model retained good fit indices. In conclusion, results diverged from theoretical predictions of physical activity, but self-determination and self-efficacy theory were still partially supported. Because the model had good fit, this study demonstrated that theoretical integration is feasible. PMID:26973926

Physical activity (PA) and nutrition are the cornerstones of diabetes management. Several reviews and meta-analyses report that PA independently produces clinically important improvements in glucose control in people with Type 2 diabetes. However, it remains unclear what the optimal strategies are to increase PA behaviour in people with Type 2 diabetes in routine primary care. This study will determine whether an evidence-informed multifaceted behaviour change intervention (Movement as Medicine for Type 2 Diabetes) targeting both consultation behaviour of primary healthcare professionals and PA behaviour in adults with Type 2 diabetes is both acceptable and feasible in the primary care setting. An open pilot study conducted in two primary care practices (phase one) will assess acceptability, feasibility and fidelity. Ongoing feedback from participating primary healthcare professionals and patients will provide opportunities for systematic adaptation and refinement of the intervention and study procedures. A two-arm parallel group clustered pilot randomised controlled trial with patients from participating primary care practices in North East England will assess acceptability, feasibility, and fidelity of the intervention (versus usual clinical care) and trial processes over a 12-month period. Consultation behaviour involving fidelity of intervention delivery, diabetes and PA related knowledge, attitudes/beliefs, intentions and self-efficacy for delivering a behaviour change intervention targeting PA behaviour will be assessed in primary healthcare professionals. We will rehearse the collection of outcome data (with the focus on data yield and quality) for a future definitive trial, through outcome assessment at baseline, one, six and twelve months. An embedded qualitative process evaluation and treatment fidelity assessment will explore issues around intervention implementation and assess whether intervention components can be reliably and faithfully delivered in routine primary care. Movement as Medicine for Type 2 Diabetes will address an important gap in the evidence-base, that is, the need for interventions to increase free-living PA behaviour in adults with Type 2 diabetes. The multifaceted intervention incorporates an online accredited training programme for primary healthcare professionals and represents, to the best of our knowledge, the first of its kind in the United Kingdom. This study will establish whether the multifaceted behavioural intervention is acceptable and feasible in routine primary care. Movement as Medicine for Type 2 Diabetes (MaMT2D) was registered with Current Controlled Trials on the 14th January 2012: ISRCTN67997502. The first primary care practice was randomised on the 5th October 2012.

A RE-AIM evaluation of theory-based physical activity interventions.

PubMed

Antikainen, Iina; Ellis, Rebecca

2011-04-01

Although physical activity interventions have been shown to effectively modify behavior, little research has examined the potential of these interventions for adoption in real-world settings. The purpose of this literature review was to evaluate the external validity of 57 theory-based physical activity interventions using the RE-AIM framework. The physical activity interventions included were more likely to report on issues of internal, rather than external validity and on individual, rather than organizational components of the RE-AIM framework, making the translation of many interventions into practice difficult. Furthermore, most studies included motivated, healthy participants, thus reducing the generalizability of the interventions to real-world settings that provide services to more diverse populations. To determine if a given intervention is feasible and effective in translational research, more information should be reported about the factors that affect external validity.

Background This paper aimed to identify the best way to engage, motivate and support early childhood services (ECS) and primary schools (PS) to create policy and practise changes to promote healthy eating and physical activity. This information would be used to develop a suitable program to implement within these children's settings to reduce the risk of childhood overweight and obesity. Methods The Medical Research Council's (UK) framework for the design and evaluation of complex interventions was used to guide the development of the healthy eating and physical activity program suitable for ECS and PS. Within this framework a range of evaluation methods, including stakeholder planning, in-depth interviews with ECS and PS staff and acceptability and feasibility trials in one local government area, were used to ascertain the best way to engage and support positive changes in these children's settings. Results Both ECS and PS identified that they had a role to play to improve children's healthy eating and physical activity. ECS identified their role in promoting healthy eating and physical activity as important for children's health, and instilling healthy habits for life. PS felt that these were health issues, rather than educational issues; however, schools saw the link between healthy eating and physical activity and student learning outcomes. These settings identified that a program that provides a simple guide that recognises good practise in these settings, such as an award scheme using a health promoting schools approach, as a feasible and acceptable way for them to support children's healthy eating and physical activity. Conclusion Through the process of design and evaluation a program - Kids - 'Go for your life', was developed to promote and support children's healthy eating and physical activity and reduce the risk of childhood overweight and obesity. Kids - 'Go for your life' used an award program, based on a health promoting schools approach, which was demonstrated to be a suitable model to engage ECS and PS and was acceptable and feasible to create policy and practise changes to support healthy eating and physical activity for children.

Undernutrition has unfavorable consequences for health and quality of life. This pilot study aimed to evaluate the feasibility of a telemonitoring intervention to improve the nutritional status of community-dwelling older adults. The study involved a one-group pretest post-test design, complemented by a qualitative study. The 3-month intervention included 20 Dutch home care clients aged >65 years and consisted of nutritional telemonitoring, television messages, and dietary advice. A process evaluation provided insight into intervention delivery and acceptability. Changes in behavioral determinants, diet quality, appetite, nutritional status, physical functioning, and quality of life were assessed. Researchers and health care professionals implemented the intervention as intended and health care professionals accepted the intervention well. However, 9 participants dropped out, and participants' acceptance was low, mainly due to the low usability of the telemonitoring television channel. Adherence to the telemonitoring measurements was good, although participants needed more help from nurses than anticipated. Participants increased compliance to several Dutch dietary guidelines and no effects on nutritional status, physical functioning, and quality of life were found. Successful telemonitoring of nutritional parameters in community-dwelling older adults starts with optimal usability and acceptability by older adults and their health care professionals. This pilot study provides insight into how to optimize telemonitoring interventions for older adults for maximum impact on behavior and health.

Lack of physical activity is a global public health issue. Behavioral change interventions utilizing smartphone applications (apps) are considered a potential solution. The purpose of this literature review was to: 1) determine whether smartphone-based interventions encourage the initiation of, and participation in, physical activity; 2) explore the success of interventions in different populations; and 3) examine the key factors of the interventions that successfully encouraged physical activity. Eight databases (Medline, Scopus, EBM Reviews–Cochrane Central Register of Controlled Trials, EBM Reviews–Cochrane Database of Systematic Reviews, PsycInfo, SportDISCUS, CINAHL, and EMBASE) were searched and studies reporting physical activity outcomes following interventions using smartphone apps in adults were included in the narrative review. Results were mixed with eight studies reporting increased physical activity and ten reporting no change. Interventions did not appear to be successful in specific populations defined by age, sex, country, or clinical diagnosis. There was no conclusive evidence that a specific behavioral theory or behavioral change technique was superior in eliciting behavioral change. The literature remains limited primarily to short-term studies, many of which are underpowered feasibility or pilot studies; therefore, many knowledge gaps regarding the effectiveness of smartphone apps in encouraging physical activity remain. Robust studies that can accommodate the fast pace of the technology industry are needed to examine outcomes in large populations. PMID:28979157

Actual and perceived physical abilities are important correlates of physical activity (PA) and fitness, but little research has explored these relationships over time in obese children. This study was designed: (a) to assess the feasibility of a multi-modal training programme promoting changes in PA, fundamental motor skills and real and perceived physical abilities of obese children; and (b) to explore cross-sectional and longitudinal relationships between real and perceived physical competence in boys and girls. Forty-one participants (9.2 ± 1.2 years) were assessed before and after an 8-month intervention with respect to body composition, physical fitness, self-reported PA and perceived physical ability. After treatment, obese children reported improvements in the body mass index, PA levels, gross motor performance and actual and perceived physical abilities. Real and perceived physical competence was correlated in boys, but not in girls. Results indicate that a multi-modal programme focused on actual and perceived physical competence as associated with the gradual increase in the volume of activity might be an effective strategy to improve adherence of the participants and to increase the lifelong exercise skills of obese children.

To determine the reliability and validity of the Physical Activity Scale for Individuals with a Physical Disability (PASIPD) in adults with severe traumatic brain injury (TBI) and estimate the proportion of the sample participants who fail to meet the World Health Organization guidelines for physical activity. A single-center observational study recruited a convenience sample of 30 community-based ambulant adults with severe TBI. Participants completed the PASIPD on 2 occasions, 1 week apart, and wore an accelerometer (ActiGraph GT3X; ActiGraph LLC, Pensacola, Florida) for the 7 days between these 2 assessments. The PASIPD test-retest reliability was substantial (intraclass correlation coefficient = 0.85; 95% confidence interval, 0.70-0.92), and the correlation with the accelerometer ranged from too low to be meaningful (R = 0.09) to moderate (R = 0.57). From device-based measurement of physical activity, 56% of participants failed to meet the World Health Organization physical activity guidelines. The PASIPD is a reliable measure of the type of physical activity people with severe TBI participate in, but it is not a valid measure of the amount of moderate to vigorous physical activity in which they engage. Accelerometers should be used to quantify moderate to vigorous physical activity in people with TBI.

Photoacoustic (PA) measurements encode the information associated with both physical microstructures and chemical contents in biological tissues. A two-dimensional physio-chemical spectrogram (PCS) can be formulated by combining the power spectra of PA signals acquired at a series of optical wavelengths. The analysis of PCS, or namely PA physio-chemical analysis (PAPCA), enables the quantification of the concentrations and the spatial distributions of a variety of chemical components in the tissue. The chemical components and their distribution are the two major features observed in the biopsy procedures which have been regarded as the gold standard of the diagnosis of many diseases. Taking non-alcoholic fatty liver disease and prostate cancer for example, this study investigates the feasibility of PAPCA in characterizing the histopathological changes in the diseased conditions in biological tissue. A catheter based setup facilitating measurement in deep tissues was also proposed and tested.

Individuals with serious mental illnesses have high rates of comorbid physical health issues and have numerous barriers to addressing their health and health care needs. The present pilot study tested the feasibility of a modified form of the "Bridge" peer-health navigator intervention delivered in a usual care setting by agency personnel. The modifications concerned the use of an electronic personal health record with individuals experiencing with housing instability. Twenty participants were randomized to receive the intervention immediately or after 6 months. Health navigator contacts and use of personal health records were associated with improvements in health care and self-management. This pilot study demonstrated promising evidence for the feasibility of adding personal health record use to a peer-led intervention.

This study analyzes the feasibility of implementing the Nursing Care Systematization in an emergency and urgency hospital department. This is a field study, descriptive, qualitative structured according to the content analysis described by Bardin (2009). It was performed in a hospital specialized in emergency care. The sample consisted of eight practical nurses, five nurses and two assistants, all of them with experience of at least six months in the emergency room. The difficulties referred to the implementation of the NCS are: complexity in their steps; disinterest of the institution; theoretical unpreparedness of nursing, its devaluation by other professionals, inadequate sizing of employees and inadequacy of the hospital physical structure. In this context, it was note that the nurse loses representation in the health team and the application of SAE turns out to be often underestimated.

There is growing consensus that exercise improves cognitive functioning, but research is needed to identify exercise interventions that optimize effects on cognition. The objective of this pilot study was to evaluate Taekwondo implemented in public middle school physical education (PE). Two classes were randomly assigned to either: five sessions per week of PE or three sessions of PE and two sessions of Taekwondo. In PE sessions, evidence-based curriculum to address the Presidential Core Fitness Guidelines and California Physical Fitness Tests was implemented. Taekwondo sessions included traditional techniques and forms taught in an environment emphasizing respect and self-control. Sixty students were evaluated at baseline and during the last week of the intervention (nine months later). Differences in mean residualized change scores for parent-rated inhibitory behavioral control yielded a significant, large effect size (d =.95, p =.00), reflecting greater improvement among Taekwondo students. Results from an executive function computer-administered task revealed greater accuracy on the congruent trial (d = 2.00, p = .02) for Taekwondo students. Differences in mean residualized change scores for BMI z scores yielded a moderate, non-significant effect size (d = − .51, p = .16). The majority of Taekwondo students reported positive perceptions of Taekwondo and perceived self-improvement in self-control and physical fitness. Results suggest that Taekwondo is an exercise program that improves cognitive functioning and is both feasible and acceptable to implement in a public school setting. PMID:24563664

Systems Analysis of Physical Absorption of CO2 in Ionic Liquids for Pre-Combustion Carbon Capture.

Zhai, Haibo; Rubin, Edward S

2018-04-17

This study develops an integrated technical and economic modeling framework to investigate the feasibility of ionic liquids (ILs) for precombustion carbon capture. The IL 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide is modeled as a potential physical solvent for CO 2 capture at integrated gasification combined cycle (IGCC) power plants. The analysis reveals that the energy penalty of the IL-based capture system comes mainly from the process and product streams compression and solvent pumping, while the major capital cost components are the compressors and absorbers. On the basis of the plant-level analysis, the cost of CO 2 avoided by the IL-based capture and storage system is estimated to be $63 per tonne of CO 2 . Technical and economic comparisons between IL- and Selexol-based capture systems at the plant level show that an IL-based system could be a feasible option for CO 2 capture. Improving the CO 2 solubility of ILs can simplify the capture process configuration and lower the process energy and cost penalties to further enhance the viability of this technology.

Despite the high prevalence of obesity among African-American women and modest success in behavioral weight loss interventions, the development and testing of weight management interventions using a community-based participatory research (CBPR) approach have been limited. Doing Me!: Sisters Standing Together for Healthy Mind and Body (Doing Me!) is an intervention adapted from an evidence-based behavioral obesity intervention using a CBPR approach. The purpose of Doing Me! is to test the feasibility and acceptability of this adapted intervention and determine its efficacy in achieving improvements in anthropometrics, diet, and physical activity. Sixty African-American women, from a low-income, urban community, aged 30-65 years will be randomized to one of two arms: 16-week Doing Me! (n = 30) or waitlist control (n = 30). Doing Me! employs CBPR methodology to involve community stakeholders and members during the planning, development, implementation, and evaluation phases of the intervention. There will be thirty-two 90-minute sessions incorporating 45 min of instruction on diet, physical activity, and/or weight management plus 45 min of physical activity. Data will be collected at baseline and post-intervention (16 weeks). Doing Me! is one of the first CBPR studies to examine the feasibility/acceptability of an adapted evidence-based behavioral weight loss intervention designed for obese African-American women. CBPR may be an effective strategy for implementing a weight management intervention among this high-risk population. Copyright © 2015 Elsevier Inc. All rights reserved.

A 16-week lunchtime walking intervention was designed to increase physical activity in physically inactive University employees. The program was delivered and monitored twice over 7 months to examine feasibility across different seasons. Seventy-five participants (n = 69 females, n = 6 males; mean age = 47.68) were randomly allocated into a Winter (February start) or Spring group (May start). Participants were asked to complete 3 weekday lunchtime walks and 2 weekend walks. Weeks 1 to 10 were led by walk leaders (group phase) while the participants self-organized their walks during weeks 11 to 16 (independent phase). Yamax pedometers recorded daily step counts and walk group leaders recorded participant attendance in the group phase. Acceptability was assessed via a satisfaction survey and 2 focus groups with participants. A participant pool representative by ethnicity, but not gender was recruited using a range of strategies. The program demonstrated good retention across both groups (73%). The intervention was acceptable to participants. More steps were accumulated in the group-led versus the independent phase. The intervention is feasible in this workplace setting across different seasonal periods. In the future, researchers should examine if the findings can be replicated in a definitive trial and generalize to other workplace settings.

Advancing the field of physical activity (PA) monitoring requires the development of innovative multi-sensor measurement systems that are feasible in the free-living environment. The use of novel analytical techniques to combine and process these multiple sensor signals is equally important. This paper describes a novel multi-sensor 'integrated PA measurement system' (IMS), the lab-based methodology used to calibrate the IMS, techniques used to predict multiple variables from the sensor signals, and proposes design changes to improve the feasibility of deploying the IMS in the free-living environment. The IMS consists of hip and wrist acceleration sensors, two piezoelectric respiration sensors on the torso, and an ultraviolet radiation sensor to obtain contextual information (indoors versus outdoors) of PA. During lab-based calibration of the IMS, data were collected on participants performing a PA routine consisting of seven different ambulatory and free-living activities while wearing a portable metabolic unit (criterion measure) and the IMS. Data analyses on the first 50 adult participants are presented. These analyses were used to determine if the IMS can be used to predict the variables of interest. Finally, physical modifications for the IMS that could enhance the feasibility of free-living use are proposed and refinement of the prediction techniques is discussed.

Objectives To explore perspectives on enhancing physical activity and diet among South Asians in urban deprived communities at high risk of chronic disease and to inform development of culturally appropriate health promotion intervention. Design Qualitative study using semistructured one-to-one and family group interviews with thematic analysis of data. Setting Urban disadvantaged communities in the East Midlands of the UK. Participants 45 respondents, including 34 people of South Asian origin (16 at-risk individuals, six family groups involving 18 relatives), of mainly Pakistani and Indian origin, including 16 non-English speakers; and 11 health professionals working locally with communities of concern. Results South Asian participants underlined the challenges of requiring family members across generations to engage in modifying dietary behaviours, and the central role of communal eating of traditional ‘Asian’ food in their cultural lives. Barriers to increasing physical activity included cost, personal safety and lack of time outside of long working hours and carer commitments. However, increasing walking activity was regarded as feasible by both community and health professional participants. Respondents emphasised using a social approach for potential interventions, undertaking activity with family or friends and with bilingual community peers to facilitate engagement, motivation and support. Spoken content and delivery of interventions was favoured, including personal stories and multilingual audio–visual information; within local informal rather than provider settings, including the home; and aided by pedometers for self-monitoring. Conclusions Focusing on physical activity by increasing walking may hold promise as health promotion in this deprived South Asian community context. Further intervention development, with exploration of feasibility and acceptability of the social approach and elements suggested, is merited. PMID:25724983

Obesity in young people is a major public health concern. Energy balance, the interrelationship between diet and physical activity, is known to be a key determinant. Evidence supports the development of school-based approaches to obesity prevention. ASSIST (A Stop Smoking in Schools Trial) is an effective school-based, peer-led smoking prevention programme for 12-13-year-old students, based on diffusion of innovations theory. The AHEAD (Activity and Healthy Eating in ADolescence) study tested the feasibility of adapting ASSIST to an obesity prevention intervention. The AHEAD intervention was tested and refined during a pilot study in one school, followed by an exploratory trial in six schools. Quantitative (self-report behavioural questionnaires and evaluation forms) and qualitative (structured observations, focus groups and interviews) research methods were used to examine the implementation and acceptability of the intervention. The potential effectiveness of the intervention in increasing healthy eating was measured using self-report behavioural questionnaires. Activity monitors (accelerometers) were used to measure physical activity. Results show it was feasible to implement the AHEAD intervention, which was well received. However, implementation was resource and labour intensive and relatively expensive. Furthermore, there was no evidence of promise that the intervention would increase physical activity or healthy eating in adolescents. Although diet and physical activity are both relevant for obesity prevention, the focus on two behaviours appeared too complex for informal diffusion through peer networks. This identifies a tension, particularly for adolescent peer-led health promotion, between the desire not to isolate or oversimplify health behaviours and the need to present clear, succinct health promotion messages. © The Author (2014).

In partnership with six Continuing Care Retirement Communities (CCRCs), the current study focused on the feasibility of recruiting a representative sample of residents and then assessing their functional health. With our guidance, each of the six CCRCs recruited a volunteer (V-Group) and random (R-Group) sample of independent living residents. We provided face-to-face training and ongoing remote electronic support to the CCRC staff on the testing battery and the Web-based data entry system. The testing battery was consisted of demographic, physical function, and psychosocial assessments. After training, CCRC staff were receptive to the study goals and successfully used the data entry Website. In the V-Group (N=189), 76% were already participating in CCRC wellness programs. We attempted to recruit a random, unbiased (R-Group) sample of 20% (n=105) of eligible residents; however, only 30 consented to be tested and 70% of this group (21/30) were also already participating in a wellness program. Mean age of all participants was 82.9 years. The V-Group had a higher Short Physical Performance Battery (SPPB) total score (least squares mean [SE], 9.4 [0.2] vs 8.2 [0.4], p=0.014) and SPPB gait speed component score (3.5 [0.1] vs 3.0 [0.2], p=0.007) and spent more time doing moderate-to-vigorous physical activity (300 [21] vs 163 [49] min/week, p=0.013) compared to the R-Group. While it is feasible to recruit, assess and transmit data on residents' functional health in partnership with CCRCs, population validity was severely compromised. Attention needs to be given to the development of more effective methods to recruit less interested residents. Copyright © 2014 Elsevier Inc. All rights reserved.

Background It is well established that drastic declines in physical activity (PA) occur during young adults’ transition into university; however, our understanding of contextual and environmental factors as it relates to young adults’ PA is limited. Objective The purpose of our study was to examine the feasibility of using wrist-worn accelerometers and the use of ecological momentary assessment (EMA) to assess the context and momentary correlates of PA on multiple occasions each day during first-year university. Methods First-year university students were asked to participate in the study. The participants completed a brief questionnaire and were subsequently asked to wear an ActiGraph GT9X-Link accelerometer and respond to a series of EMA prompts (7/day) via their phones for 5 consecutive days. Results A total of 96 first-year university students with smartphones agreed to participate in the study (mean age 18.3 [SD 0.51]; n=45 females). Overall, there was good compliance for wearing the accelerometers, with 91% (78/86) of the participants having ≥2 days of ≥10 hours of wear time (mean=3.53 valid days). Students were generally active, averaging 10,895 steps/day (SD 3413) or 1123.23 activity counts/min (SD 356.10). Compliance to EMA prompts was less desirable, with 64% (55/86) of the participants having usable EMA data (responding to a minimum of ≥3 days of 3 prompts/day or ≥4 days of 2 prompts/day), and only 47% (26/55) of these participants were considered to have excellent EMA compliance (responding to ≥5 days of 4 prompts/day or ≥ 4 days of 5 prompts/day). Conclusions This study represents one of the first studies to use an intensive real-time data capture strategy to examine time-varying correlates of PA among first-year university students. These data will aim to describe the physical and social contexts in which PA occurs and examine the relationships between momentary correlates of PA among the first-year university students. Overall, current results suggest that wrist-worn accelerometers and EMA are feasible methods for data collection among the young adult population; however, more work is needed to understand how to improve upon compliance to a real-time data capture method such as EMA.

2015-10-20

This paper presents the study of the feasibility of incorporating lignocellulosic nanofibers (LCNF) to paper in order to maintain the relevant physical properties and increase the number of cycles that paper can be recycled in the technosphere in a more circular economy. For that purpose, the effect of mechanical refining in recycling processes was compared with that of the novel LCNF addition. In this sense, the behavior of a bleached kraft hardwood pulp when recycled was investigated, as well as the effects of each methodology. Since there are many issues to be considered when trying to replace a technology, the present paper analyses its feasibility from a technical and environmental point of view. Technically, LCNF present greater advantages against mechanical refining, such as higher mechanical properties and longer durability of the fibers. A preliminary life cycle assessment showed that the environmental impacts of both systems are very similar; however, changing the boundary conditions to some feasible future scenarios, led to demonstrate that the CNF technology may improve significantly those impacts.

This report considers feasibility of conducting a UK trial of combination devices for tinnitus, using data from the study which evaluated different listener programmes available within the pre-market version of Oticon Alta with Tinnitus Sound Generator. Open and closed questions addressed the following feasibility issues: (1) Participant recruitment; (2) Device acceptability; (3) Programme preferences in different self-nominated listening situations; (4) Usability; (5) Compliance; (6) Adverse events. Eight current combination hearing aid users (all males) aged between 62-72 years (mean age 67.25 years, SD = 3.8). All eight participants reported the physical aspects and noise options on the experimental device to be acceptable. Programmes with amplification and masking features were equally preferred over the basic amplification-only programme. Individual preferences for the different programme options varied widely, both across participants and across listening situations. A set of recommendations for future trials were formulated which calls for more "real world" trial design rather than tightly controlling the fitting procedure.

Droplet burning at zero G

1978-01-01

Questions of the importance and feasibility of performing experiments on droplet burning at zero gravity in Spacelab were studied. Information on the physics and chemistry of droplet combustion, with attention directed specifically to the chemical kinetics, heat and mass transfer, and fluid mechanics of the phenomena involved, are presented. The work was divided into three phases, the justification, the feasibility, and the conceptual development of a preliminary design. Results from the experiments performed revealed a few new facts concerning droplet burning, notably burning rates in excess of theoretical prediction and a phenomenon of flash extinction, both likely traceable to accumulation of carbon produced by gas-phase pyrolysis in the fuel-rich zone enclosed by the reaction surface. These experiments also showed that they were primarily due to timing difficulties.

Walking school buses (WSB) increased children's physical activity, but impact on pedestrian safety behaviors (PSB) is unknown. We tested the feasibility of a protocol evaluating changes to PSB during a WSB program. Outcomes were school-level street crossing PSB prior to (Time 1) and during weeks 4-5 (Time 2) of the WSB. The protocol collected 1252 observations at Time 1 and 2548 at Time 2. Mixed model analyses yielded: intervention schoolchildren had 5-fold higher odds (p<0.01) of crossing at the corner/crosswalk but 5-fold lower odds (p<0.01) of stopping at the curb. The protocol appears feasible for documenting changes to school-level PSB. Copyright © 2011 Elsevier Ltd. All rights reserved.

Early exercise with in-bed cycling as part of an intensive care unit (ICU) rehabilitation programme has the potential to improve physical and functional outcomes following critical illness. The objective of this study is to determine the feasibility of enrolling adults in a multicentre pilot randomised clinical trial (RCT) of early in-bed cycling versus routine physiotherapy to inform a larger RCT. 60-patient parallel group pilot RCT in 7 Canadian medical-surgical ICUs. We will include all previously ambulatory adult patients within the first 0-4 days of mechanical ventilation, without exclusion criteria. After informed consent, patients will be randomised using a web-based, centralised electronic system, to 30 min of in-bed leg cycling in addition to routine physiotherapy, 5 days per week, for the duration of their ICU stay (28 days maximum) or routine physiotherapy alone. We will measure patients' muscle strength (Medical Research Council Sum Score, quadriceps force) and function (Physical Function in ICU Test (scored), 30 s sit-to-stand, 2 min walk test) at ICU awakening, ICU discharge and hospital discharge. Our 4 feasibility outcomes are: (1) patient accrual of 1-2 patients per month per centre, (2) protocol violation rate <20%, (3) outcome measure ascertainment >80% at the 3 time points and (4) blinded outcomes ascertainment >80% at hospital discharge. Hospital outcome assessors are blinded to group assignment, whereas participants, ICU physiotherapists, ICU caregivers, research coordinators and ICU outcome assessors are not blinded to group assignment. We will analyse feasibility outcomes with descriptive statistics. Each participating centre will obtain local ethics approval, and results of the study will be published to inform the design and conduct of a future multicentre RCT of in-bed cycling to improve physical outcomes in ICU survivors.

The purpose of this work was to study the feasibility of an individual Parkinson disease (PD) rehabilitation program based on each patient's prevalent symptoms and to determine the effects of this program on patient's quality of life as well as the level of patient's and physiotherapist's satisfaction with the program. In association with physiotherapists with expertise in PD, a physical medicine and rehabilitation physician, we elaborated a physical therapy program based on the core areas for physical therapy in PD: transfers; posture; balance and falls; physical capacity and inactivity. Within this program, we selected exercises tailored to each patient's main impairment and proposed this selection to their local physiotherapist for three months. Quality of life was evaluated with PDQ-39 at baseline and after three months of the individualized physical therapy program. We built an anonymous satisfaction questionnaire for patients and physiotherapists that was filled out at the end of the program. One hundred and three individuals with moderately advanced but clinically stable idiopathic PD were included. Significant improvement was found for the emotional well-being, bodily discomfort and stigma domain (P ≤ 0.05). No significant improvement was found for the other PDQ-39 domains. The mean global satisfaction figures for this program were 6.0 ± 2.4 and 7.2 ± 2.1 for patients and physiotherapists respectively. Most of the patients felt improved by the physiotherapy program and especially for transfer, balance, gait, and mobility. Our study found evidence of the potential benefits of a patient-tailored physiotherapy program. Such a program was feasible and had a favorable impact on patients' quality of life and on physiotherapists' practices for PD patients. Specific physiotherapy may be effective to limit physical mobility impairment. Our results also pointed out that physiotherapy may be efficient to confine the negative impact of social isolation, pain and emotional reactions. Such a program should be associated with a therapeutic education intervention such as encouraging patients to perform physical therapy exercises alone. Copyright © 2014 Elsevier Masson SAS.

Low levels of physical activity and sedentary behaviour are a growing health problem globally. Physical inactivity is associated with increased risk of numerous ailments, cardiovascular disease and mortality. Our primary aim was to perform a feasibility study on how to incorporate physical activity among students and teachers in regular teaching activities. The second aim was to investigate how students and teachers perceived the differences between outdoor walking seminars and regular indoor seminars. By transforming an on-campus course into a blended course, we were able to conduct seminars outdoors in nearby nature while walking. These walking seminars were evaluated among 131 students and nine teachers leading the walking seminars. The responses to the student survey and teacher interviews indicate that discussions, sense of well-being and the general quality of the seminar improved, regardless of how physically active participants were the rest of the time. The study shows one way to increase physical activity with small means; in our case, a reorganization of how we prepared for the seminars which allowed for walking discussions. PMID:29425171

Prolonged sitting time has been identified as a health risk factor. Sit-stand workstations allow desk workers to alternate between sitting and standing throughout the working day, but not much is known about their acceptability and feasibility. Hence, the aim of this study was to qualitatively evaluate the acceptability, feasibility and perceptions of using sit-stand workstations in a group of desk-based office workers. This article describes the qualitative evaluation of the randomized controlled cross-over Stand@Work pilot trial. Participants were adult employees recruited from a non-government health agency in Sydney, Australia. The intervention involved using an Ergotron Workfit S sit-stand workstation for four weeks. After the four week intervention, participants shared their perceptions and experiences of using the sit-stand workstation in focus group interviews with 4-5 participants. Topics covered in the focus groups included patterns of workstation use, barriers and facilitators to standing while working, effects on work performance, physical impacts, and feasibility in the office. Focus group field notes and transcripts were analysed in an iterative process during and after the data collection period to identify the main concepts and themes. During nine 45-min focus groups, a total of 42 participants were interviewed. Participants were largely intrinsically motivated to try the sit-stand workstation, mostly because of curiosity to try something new, interest in potential health benefits, and the relevance to the participant's own and organisation's work. Most participants used the sit-stand workstation and three common usage patterns were identified: task-based routine, time-based routine, and no particular routine. Common barriers to sit-stand workstation use were working in an open plan office, and issues with sit-stand workstation design. Common facilitators of sit-stand workstation use were a supportive work environment conducive to standing, perceived physical health benefits, and perceived work benefits. When prompted, most participants indicated they were interested in using a sit-stand workstation in the future. The use of a sit-stand workstation in this group of desk-based office workers was generally perceived as acceptable and feasible. Future studies are needed to explore this in different desk-based work populations and settings.

To undertake the pre-clinical and modelling phases of the Medical Research Council complex intervention framework to underpin development of child-centred 'keep-fit', exercise and physical activity interventions for children and young people who use wheelchairs. Children who use wheelchairs face many barriers to participation in physical activity, which compromises fitness, obesity, well-being and health. 'Keep-fit' programmes that are child-centred and engaging are urgently required to enhance participation of disabled children and their families as part of a healthy lifestyle. Nurses will likely be important in promoting and monitoring 'keep-fit' intervention(s) when implemented in the community. Mixed-method (including economic analysis) feasibility study to capture child and family preferences and keep-fit needs and to determine outcome measures for a 'keep-fit' intervention. The study comprises three stages. Stage 1 includes a mixed-method systematic review of effectiveness, cost effectiveness and key stakeholder views and experiences of keep-fit interventions, followed by qualitative interviews with children, young people and their parents to explore preferences and motivations for physical activity. Stage 2 will identify standardized outcome measures and test their application with children who use wheelchairs to obtain baseline fitness data. Options for an exercise-based keep-fit intervention will then be designed based on Stage 1 and 2 findings. In stage 3, we will present intervention options for feedback and further refinement to children and parents/carers in focus groups. (Project funded October 2012). At completion, this study will lead to the design of the intervention and a protocol to test its efficacy. © 2014 John Wiley & Sons Ltd.

Challenges remain to find ways to support patients with depression who have low levels of physical activity (PA) to overcome perceived barriers and enhance the perceived value of PA for preventing future relapse. There is an evidence-base for behavioural activation (BA) for depression, which focuses on supporting patients to restore activities that have been avoided, but practitioners have no specific training in promoting PA. We aimed to design and evaluate an integrated BA and PA (BAcPAc) practitioner-led, written, self-help intervention to enhance both physical and mental health. This study is informed by the Medical Research Council Complex Intervention Framework and describes a protocol for a pilot phase II randomised controlled trial (RCT) to test the feasibility and acceptability of the trial methods to inform a definitive phase III RCT. Following development of the augmented written self-help intervention (BAcPAc) incorporating behavioural activation with physical activity promotion, depressed adults are randomised to receive up to 12 sessions over a maximum of 4 months of either BAcPAc or behavioural activation alone within a written self-help format, which represents treatment as usual. The study is located within two 'Improving Access to Psychological Therapies' services in South West England, with both written self-help interventions supported by mental health paraprofessionals. Measures assessed at 4, 9, and 12 month follow-up include the following: CIS-R, PHQ-9, accelerometer recorded (4 months only) and self-reported PA, body mass index, blood pressure, Insomnia Severity Index, quality of life, and health and social care service use. Process evaluation will include analysis of recorded support sessions and patient and practitioner interviews. At the time of writing the study has recruited 60 patients. The feasibility outcomes will inform a definitive RCT to assess the clinical and cost-effectiveness of the augmented BAcPAc written self-help intervention to reduce depression and depressive relapse, and bring about improvements across a range of physical health outcomes.

Using a quasi-experimental single-group design, this study examined the feasibility of older adults with Alzheimer's disease (AD)-type dementia to complete the Sit 'N' Fit Chair Yoga Program. Physical function of participants who completed the program was measured. The nine older adults with AD (mean age = 83) participated in the 8-week Sit 'N' Fit Chair Yoga Program. To measure physical function, the Six-Minute Walk Test, the Gait Speed Test, and the Berg Balance Scale were administered at pre-intervention, 4 weeks, 8 weeks, and 1 month after program completion. All participants completed the program. Positive changes were seen across all physical measures. Further study, using a larger sample and including a control group, is needed to fully determine the effect of the Sit 'N' Fit Chair Yoga Program on older adults with moderate to severe AD.

Little is known about how aerobic exercise affects physical functioning in persons with Alzheimer's disease (AD). This pilot study used a 1-group repeated measures design to examine the feasibility and impact of a 6-month individualized moderate intensity cycling intervention on cardiorespiratory fitness and lower extremity function in 8 participants aged 81.4 ± 3.58. Cardiorespiratory fitness was measured using the shuttle walk and modified YMCA cycle ergometer tests, and lower extremity function was measured using the Short Physical Performance Battery (SPPB) at baseline, 3 months and 6 months. The YMCA test showed a significant reduction in heart rate at stage 2 (103.4 vs 90.9 vs 91.6; P = .01), while no significant changes were observed in the shuttle walk and SPPB tests. Persons with AD are able to improve cardiorespiratory conditioning from aerobic exercise. Randomized, controlled trials are needed to confirm these findings. Implications for future research are detailed.

A process and apparatus generates a sequence of steps for assembly or disassembly of a mechanical system. Each step in the sequence is geometrically feasible, i.e., the part motions required are physically possible. Each step in the sequence is also constraint feasible, i.e., the step satisfies user-definable constraints. Constraints allow process and other such limitations, not usually represented in models of the completed mechanical system, to affect the sequence.

This report describes the accelerator studies for a future multi-TeV e +e - collider based on the Compact Linear Collider (CLIC) technology. The CLIC concept as described in the report is based on high gradient normal-conducting accelerating structures where the RF power for the acceleration of the colliding beams is extracted from a high-current Drive Beam that runs parallel with the main linac. The focus of CLIC R&D over the last years has been on addressing a set of key feasibility issues that are essential for proving the fundamental validity of the CLIC concept. The status of these feasibility studiesmore » are described and summarized. The report also includes a technical description of the accelerator components and R&D to develop the most important parts and methods, as well as a description of the civil engineering and technical services associated with the installation. Several larger system tests have been performed to validate the two-beam scheme, and of particular importance are the results from the CLIC test facility at CERN (CTF3). Both the machine and detector/physics studies for CLIC have primarily focused on the 3 TeV implementation of CLIC as a benchmark for the CLIC feasibility. This report also includes specific studies for an initial 500 GeV machine, and some discussion of possible intermediate energy stages. The performance and operation issues related to operation at reduced energy compared to the nominal, and considerations of a staged construction program are included in the final part of the report. The CLIC accelerator study is organized as an international collaboration with 43 partners in 22 countries. An associated report describes the physics potential and experiments at CLIC and a shorter report in preparation will focus on the CLIC implementation strategy, together with a plan for the CLIC R&D studies 2012–2016. Critical and important implementation issues such as cost, power and schedule will be addressed there.« less

Musculoskeletal disorders, such as knee pain, are common in children and adolescents, but there is a lack of high quality research that evaluates the clinical course of these conditions. The objective of this study was to evaluate the feasibility of conducting a prospective study of children and adolescents with knee pain using electronic methods of data collection. Children and adolescents with knee pain that presented to primary care physiotherapy clinics were enrolled and followed-up on a weekly basis via short messaging service (SMS) until their knee pain had recovered (i.e. two consecutive weeks of no pain). Feasibility was assessed in terms of recruitment, retention and response rates to SMS and an online questionnaire. Baseline and 6-month follow-up measures included pain, disability, physical function, physical activity and health related quality of life. Kaplan-Meier survival analysis was used to estimate the median time to knee pain recovery. Thirty participants (mean age 13.0 ± 2.2 years, 53% boys) were recruited over 26 months. The overall response rate to weekly SMS follow-up was 71.3% (809 received/1135 sent). One third of participants stopped responding to SMS prior to recovery, and these participants typically had a much lower response rate during the time they remained in the study. At 6-month follow-up, 80% of the cohort completed the final online questionnaire, and 29% of participants still reported current knee pain (≥1/10 VAS). The median time for knee pain recovery was 8 weeks (95%CI: 5, 10). Electronic data collection alone seems insufficient to track pain recovery in young people and may need to be supplemented with more traditional data collection methods. Researchers should consider further measures to address slow recruitment rates and high attrition when designing large prospective studies of children and adolescents in the future.

Prolonged sedentary behavior is an independent risk factor for multiple negative health outcomes. Evidence supports introducing standing desks into K-12 classrooms and work settings to reduce sitting time, but no studies have been conducted in the college classroom environment. The present study explored the acceptability and feasibility of introducing standing desks in college classrooms. A total of 993 students and 149 instructors completed a single online needs assessment survey. This cross-sectional study was conducted during the fall semester of 2015 at a large Midwestern University. The large majority of students (95%) reported they would prefer the option to stand in class. Most students (82.7%) reported they currently sit during their entire class time. Most students (76.6%) and instructors (86.6%) reported being in favor of introducing standing desks into college classrooms. More than half of students and instructors predicted having access to standing desks in class would improve student’s “physical health”, “attention”, and “restlessness”. Collectively, these findings support the acceptability of introducing standing desks in college classrooms. Future research is needed to test the feasibility, cost-effectiveness and efficacy of introducing standing desks in college classrooms. Such studies would be useful for informing institutional policies regarding classroom designs. PMID:27537901

Workplaces have potential as a setting for physical activity promotion but evidence of the effectiveness of intervention programmes in small and medium sized enterprises is limited. This paper reports the impact of an intervention which trained existing employees to promote physical activity to their colleagues. Eighty-nine previously low-active employees from 17 small and medium sized organisations participated. A mixed methods evaluation design was used. Quantitative data were collected at baseline and 6 months later using an online questionnaire. Qualitative data from a series of 6 focus groups were analysed. Repeated measures t-tests showed significant increases over time in physical activity, general health rating, satisfaction with life and positive mood states. There were significant decreases in body mass index (BMI), perceived stress, negative mood states and presenteeism. There was no change in absenteeism. Analysis of focus group data provided further insight into the impact of the intervention. Five major themes emerged: awareness of physical activity; sustaining physical activity behaviour change; improved health and well-being; enhanced social networks; and embedding physical activity in the workplace culture. This study shows it is feasible and effective to train employees in small and medium sized enterprises to support their colleagues in physical activity behaviour change.

The purpose of this study was to describe the feasibility of using a community-based participatory research (CBPR) approach to implement the Power to Prevent (P2P) diabetes prevention education curriculum in rural African American (AA) settings. Trained community health workers facilitated the 12-session P2P curriculum across 3 community settings. Quantitative (based on the pre- and post-curriculum questionnaires and changes in blood glucose, blood pressure [BP], and weight at baseline and 6 months) and qualitative data (based on semi-structured interviews with facilitators) were collected. Indicators of feasibility included: demand, acceptability, implementation fidelity, and limited efficacy testing. Across 3 counties, 104 AA participants were recruited; 43% completed ≥ 75% of the sessions. There was great demand for the program. Fifteen community health ambassadors (CHAs) were trained, and 4 served as curriculum facilitators. Content and structure of the intervention was acceptable to facilitators but there were challenges to implementing the program as designed. Improvements were seen in diabetes knowledge and the impact of healthy eating and physical activity on diabetes prevention, but there were no significant changes in blood glucose, BP, or weight. While it is feasible to use a CBPR approach to recruit participants and implement the P2P curriculum in AA community settings, there are significant challenges that must be overcome.

Most breast cancer survivors do not engage in regular physical activity. Our physical activity behavior change intervention for breast cancer survivors significantly improved physical activity and health outcomes post-intervention during a pilot, feasibility study. Testing in additional sites with a larger sample and longer follow-up is warranted to confirm program effectiveness short and longer term. Importantly, the pilot intervention resulted in changes in physical activity and social cognitive theory constructs, enhancing our potential for testing mechanisms mediating physical activity behavior change. Here, we report the rationale, design, and methods for a two-site, randomized controlled trial comparing the effects of the BEAT Cancer physical activity behavior change intervention to usual care on short and longer term physical activity adherence among breast cancer survivors. Secondary aims include examining social cognitive theory mechanisms of physical activity behavior change and health benefits of the intervention. Study recruitment goal is 256 breast cancer survivors with a history of ductal carcinoma in situ or Stage I, II, or IIIA disease who have completed primary cancer treatment. Outcome measures are obtained at baseline, 3 months (i.e., immediately post-intervention), 6 months, and 12 months and include physical activity, psychosocial factors, fatigue, sleep quality, lower extremity joint dysfunction, cardiorespiratory fitness, muscle strength, and waist-to-hip ratio. Confirming behavior change effectiveness, health effects, and underlying mechanisms of physical activity behavior change interventions will facilitate translation to community settings for improving the health and well-being of breast cancer survivors.

The purpose of this study is to explore barriers and needs related to diabetes care and the feasibility of diabetes self-management (DSM) "coaching" at faith-based organizations (FBOs) for the Indo-Guyanese community in Schenectady, New York. Participants were recruited though flyers and mass mailings, and in-depth interviews were conducted at their homes by a team of culturally matched interviewers using a semi-structured questionnaire. Characteristics of participants were compared with existing population-based data to confirm their representativeness. Responses were transcribed, coded, and summarized, and findings are presented along with selective quotations. Key dimensions of feasibility were scored and charted for visualization. Findings revealed barriers regarding diet-related knowledge and skills, access to structured DSM education, hyperglycemia control, and environmental support for physical activity. Participants responded positively to receiving free DSM coaching at their FBOs. All participants preferred a qualified health care professional such as certified diabetes educator as their coach and wanted coaching in all aspects of DSM; however, food preparation/diet was the most frequently requested specific topic. Participants uniformly disliked contact with the coach through e-mails and text messages but liked receiving periodic telephone calls at home by the coach. Overall, DSM coaching at FBOs rated high on the key dimensions of feasibility, namely, affordability, accessibility, acceptability, cultural relevance, and safety. This study sheds light on the feasibility of an FBO-based DSM intervention for the Indo-Guyanese. It offers insights into developing culturally appropriate DSM intervention format and strategy. © 2015 The Author(s).

Sedentary behaviours have been linked to poor health, independent of physical activity levels. The objective of this study was to explore an individualised intervention strategy aimed at reducing sedentary behaviours in older Scottish adults. This feasibility and pilot study was a pre-experimental (one group pretest-posttest) study design. Participants were enrolled into the study in January-March 2012 and data analysis was completed April-October 2012. The study was based in Glasgow, Scotland. Participants received an individualised consultation targeting sedentary behaviour incorporating feedback from an activPAL activity monitor. Outcome measures were objectively (activPAL) and subjectively measured (Sedentary Behaviour Questionnaire) sedentary time. Twenty four participants received the intervention. Objectively measured total time spent sitting/lying was reduced by 24 min/day (p=0.042), a reduction of 2.2%. Total time spent in stepping activities, such as walking increased by 13 min/day (p=0.044). Self-report data suggested participants achieved behaviour change by reducing time spent watching television and/or using motorised transport. Interventions to reduce sedentary behaviours in older people are urgently needed. The results of this feasibility and pilot study suggest a consultation approach may help individuals reduce time spent in sedentary behaviours. A larger, controlled trial is warranted with a diverse sample to increase generalisability. © 2013.

African immigrants are one of the fastest growing immigrant groups to the United States; there is a crucial need to learn about African immigrants' beliefs and lifestyle behaviors that may impact health. The purposes of this study were to (a) explore the perceptions and practices of Nigerian immigrants regarding healthy eating and physical activity in the United States; (b) assess the influence of cultural beliefs of Nigerian immigrants on eating and physical activity; (c) describe the role that healthcare providers can play in helping to promote healthy eating and physical activity; and (d) evaluate the feasibility and efficacy of using Photovoice to collect data on the perceptions and practices of Nigerian immigrants regarding healthy eating and physical activity. Qualitative visual ethnography using Photovoice. Thirteen Nigerian immigrants were recruited. Data were collected using photography and focus group discussions at a church. Photovoice methodology and Leininger's four phases of qualitative analysis were used to analyze photographs, field notes, and focus group transcripts. Four overarching themes emerged from the data: moderation is healthy, Nigerian ways of living are healthy, acquiring American ways is unhealthy, and cultural context is important to promote healthy behaviors. Photovoice was a feasible, effective methodology for collecting data on the perceptions and practices of Nigerian immigrants. Nigerian participants believed that adherence to traditional dietary and activity practices are healthy. Nurses and other healthcare providers must make concerted efforts to communicate with and educate Nigerian immigrants about healthful eating and activity behaviors within their cultural context. The number of African immigrants to the United States has increased dramatically. Photovoice is a creative method to learn about the health beliefs and behaviors of the Nigerian immigrant population. © 2014 Sigma Theta Tau International.

Facilitating healthy levels of physical activity (PA) during chemotherapy is important for the psychosocial and physical health of breast cancer survivors. The primary objective of this feasibility study was to examine the effects of a broad-reach PA behavior change intervention among women with breast cancer receiving adjuvant chemotherapy. Breast cancer patients receiving adjuvant chemotherapy (N = 95) were randomly assigned to receive a PA resource kit consisting of tailored print materials and a step pedometer (intervention) or a standard public health PA recommendation (standard recommendation). The primary outcome was daily pedometer steps. Secondary outcomes were self-reported light, moderate, and vigorous intensity PA, total moderate-to-vigorous PA, and sedentary time. Assessments were conducted before and after adjuvant chemotherapy. Attrition was 19% (17 of 95). Intervention patients wore their step pedometer for 85 days (range, 35-144 days; SD = 26.4) for a 95% adherence rate. Analyses of covariance suggested that the intervention was not statistically superior to standard recommendation for daily average pedometer steps (-771; 95% CI = -2024 to 482; P = 0.22), total MVPA minutes (-4; 95% CI = -62 to 570; P = 0.90), or sedentary time (+160; 95% CI = -186 to 506; P = 0.42). This broach-reach and low intensive intervention was not more effective for promoting PA in breast cancer patients receiving chemotherapy than providing the standard public health guidelines for PA. Achieving physical activity behavior change during adjuvant breast cancer chemotherapy may require some level of supervised physical activity or more intensive (e.g., face-to-face, supervised) interventions. ©2015 American Association for Cancer Research.

There are few studies using animal models in chest physical therapy. However, there are no models to assess these effects in newborns. This study aimed to develop a model of obstructive atelectasis induced by artificial mucus injection in the lungs of newborn piglets, for the study of neonatal physiotherapy. Thirteen newborn piglets received artificial mucus injection via the endotracheal tube. X-rays and blood gas analysis confirmed the atelectasis. The model showed consistent results between oxygenation parameters and radiological findings. Ten (76.9%) of the 13 piglets responded to the intervention. This did not significantly differ from the expected percentage of 50% by the binomial test (95% CI 46.2-95%, P = .09). Our model of atelectasis in newborn piglets is both feasible and appropriate to evaluate the impact of physical therapies on atelectasis in newborns.

Breast cancer is the most commonly diagnosed cancer and the second cause of cancer deaths amongst women in the UK. The incidence of the disease is increasing and is highest in women from least deprived areas. It is estimated that around 42% of the disease in post-menopausal women could be prevented by increased physical activity and reductions in alcohol intake and body fatness. Breast cancer control endeavours focus on national screening programmes but these do not include communications or interventions for risk reduction. This study aimed to assess the feasibility of delivery, indicative effects and acceptability of a lifestyle intervention programme initiated within the NHS Scottish Breast Screening Programme (NHSSBSP). A 1:1 randomised controlled trial (RCT) of the 3 month ActWell programme (focussing on body weight, physical activity and alcohol) versus usual care conducted in two NHSSBSP sites between June 2013 and January 2014. Feasibility assessments included recruitment, retention, and fidelity to protocol. Indicative outcomes were measured at baseline and 3 month follow-up (body weight, waist circumference, eating and alcohol habits and physical activity). At study end, a questionnaire assessed participant satisfaction and qualitative interviews elicited women's, coaches, and radiographers' experiences. Statistical analysis used Chi squared tests for comparisons in proportions and paired t tests for comparisons of means. Linear regression analyses were performed, adjusted for baseline values, with group allocation as a fixed effect. A pre-set recruitment target of 80 women was achieved within 12 weeks and 65 (81%) participants (29 intervention, 36 control) completed 3 month assessments. Mean age was 58 ± 5.6 years, mean BMI was 29.2 ± 7.0 kg/m(2) and many (44%) reported a family history of breast cancer. The primary analysis (baseline body weight adjusted) showed a significant between group difference favouring the intervention group of 2.04 kg (95% CI -3.24 kg to -0.85 kg). Significant, favourable between group differences were also detected for BMI, waist circumference, physical activity and sitting time. Women rated the programme highly and 70% said they would recommend it to others. Recruitment, retention, indicative results and participant acceptability support the development of a definitive RCT to measure long term effects. The trial was registered with Current Controlled Trials (ISRCTN56223933).

Even in countries with universal healthcare systems, excess mortality rates due to physical chronic diseases in patients also suffering from serious mental illness like schizophrenia is such that their life expectancy could be lessened by up to 20 years. The possible explanations for this disparity include: unhealthy habits (i.e. smoking; lack of exercise); side-effects of psychotropic medication; delays in the detection or initial presentation leading to a more advanced disease at diagnosis; and inequity of access to services. The main objective of this paper is to explore the feasibility and acceptability of patient partnership for developing an interactive guide to improve access to primary care providers for chronic diseases management and health promotion among patients with severe mental illnesses. A participatory action research design was used to engage patients with mental illness as full research partners for a strategy for patient-oriented research in primary care for persons with schizophrenia who also have chronic physical illnesses. This strategy was also developed in partnership with a health and social services centre responsible for the health of the population of a territory with about 100,000 inhabitants in East-end Montreal, Canada. A new interactive guide was developed by patient research partners and used by 146 participating patients with serious mental illness who live on this territory, for them to be better prepared for their medical appointment with a General Practitioner by becoming more aware of their own physical condition. Patient research partners produced a series of 33 short videos depicting signs and symptoms of common chronic diseases and risk factors for the leading causes of mortality and study participants were able to complete the corresponding 33-item questionnaire on an electronic touch screen tablet. What proved to be most relevant in terms of interactivity was the dynamic that has developed among the study participants during the small group learning sessions, a training technique designed for healthcare professionals that was adapted for this project for, and with patient partners. This research has shown the feasibility and acceptability of patient partnership and patient-oriented research approaches to the R&D process of a new medical tool and intervention for patients with serious mental illness, and its acceptability for addressing inequity of this disadvantaged population in terms of access to primary care providers.

National guidelines recommend that patients with a cancer diagnosis engage in regular physical activity to reduce cancer-related fatigue, maintain quality of life and physical function, and improve overall prognosis and survival. This study investigates oncology provider communications about physical activity during routine clinic visits with patients with early-stage breast, colon, or prostate cancer. This study used a retrospective chart review for documentation of inquiries or recommendations pertaining to physical activity in clinician notes and after-visit patient summaries. In a 1-month period, 55 oncology providers had 361 encounters (clinic visits) with early-stage cancer patients. Thirty-five percent of these encounters included a provider communication about "physical activity," "exercise," or "activity." Encounters with a medical oncologist resulted in a physical activity communication 55% of the time, whereas encounters with other clinician specialties did so 20% of the time (P < .0001). The likelihood of a physical activity communication increased with patient age (P < .001). When the encounter was with a patient who was being seen for surveillance, chemotherapy, or endocrine treatment, the rate of physical activity communications was significantly higher (46%, 37%, and 58%, respectively) than the rate when the visit was during radiation treatment or surgery (6% and 19%, respectively; P < .0001). This study shows that it is feasible for oncology providers to have physical activity communications during routine clinic visits; however, the frequency of physical activity communications varies among providers. Interventions are needed to remind and encourage all oncology providers to encourage their patients with early-stage cancer to be physically active. . © 2015 American Cancer Society.

Influences of 12-Week Physical Activity Interventions on TMS Measures of Cortical Network Inhibition and Upper Extremity Motor Performance in Older Adults—A Feasibility Study

Objective: Data from previous cross-sectional studies have shown that an increased level of physical fitness is associated with improved motor dexterity across the lifespan. In addition, physical fitness is positively associated with increased laterality of cortical function during unimanual tasks; indicating that sedentary aging is associated with a loss of interhemispheric inhibition affecting motor performance. The present study employed exercise interventions in previously sedentary older adults to compare motor dexterity and measure of interhemispheric inhibition using transcranial magnetic stimulation (TMS) after the interventions. Methods: Twenty-one community-dwelling, reportedly sedentary older adults were recruited, randomized and enrolled to a 12-week aerobic exercise group or a 12-week non-aerobic exercise balance condition. The aerobic condition was comprised of an interval-based cycling “spin” activity, while the non-aerobic “balance” exercise condition involved balance and stretching activities. Participants completed upper extremity dexterity batteries and estimates of VO2max in addition to undergoing single (ipsilateral silent period—iSP) and paired-pulse interhemispheric inhibition (ppIHI) in separate assessment sessions before and after study interventions. After each intervention during which heart rate was continuously recorded to measure exertion level (load), participants crossed over into the alternate arm of the study for an additional 12-week intervention period in an AB/BA design with no washout period. Results: After the interventions, regardless of intervention order, participants in the aerobic spin condition showed higher estimated VO2max levels after the 12-week intervention as compared to estimated VO2max in the non-aerobic balance intervention. After controlling for carryover effects due to the study design, participants in the spin condition showed longer iSP duration than the balance condition. Heart rate load was more strongly correlated with silent period duration after the Spin condition than estimated VO2. Conclusions: Aging-related changes in cortical inhibition may be influenced by 12-week physical activity interventions when assessed with the iSP. Although inhibitory signaling is mediates both ppIHI and iSP measures each TMS modality likely employs distinct inhibitory networks, potentially differentially affected by aging. Changes in inhibitory function after physical activity interventions may be associated with improved dexterity and motor control at least as evidence from this feasibility study show. PMID:29354049

Methodologically, to assess the feasibility of participant recruitment and retention, as well as missing data in studying mental disorder among children newly diagnosed with chronic physical conditions (ie, multimorbidity). Substantively, to examine the prevalence of multimorbidity, identify sociodemographic correlates and model the influence of multimorbidity on changes in child quality of life and parental psychosocial outcomes over a 6-month follow-up. Prospective pilot study. Two children's tertiary-care hospitals. Children aged 6-16 years diagnosed in the past 6 months with one of the following: asthma, diabetes, epilepsy, food allergy or juvenile arthritis, and their parents. Response, participation and retention rates. Child mental disorder using the Mini International Neuropsychiatric Interview at baseline and 6 months. Child quality of life, parental symptoms of stress, anxiety and depression, and family functioning. All outcomes were parent reported. Response, participation and retention rates were 90%, 83% and 88%, respectively. Of the 50 children enrolled in the study, the prevalence of multimorbidity was 58% at baseline and 42% at 6 months. No sociodemographic characteristics were associated with multimorbidity. Multimorbidity at baseline was associated with declines over 6 months in the following quality of life domains: physical well-being, β=-4.82 (-8.47, -1.17); psychological well-being, β=-4.10 (-7.62, -0.58) and school environment, β=-4.17 (-8.18, -0.16). There was no association with parental psychosocial outcomes over time. Preliminary evidence suggests that mental disorder in children with a physical condition is very common and has a negative impact on quality of life over time. Based on the strong response rate and minimal attrition, our approach to study child multimorbidity appears feasible and suggests that multimorbidity is an important concern for families. Methodological and substantive findings from this pilot study have been used to implement a larger, more definitive study of child multimorbidity, which should lead to important clinical implications. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2007-11-01

The progress of strangeness physics at COSY in both experimental and theoretical aspects is reviewed. It is argued that the dynamics of hyperon production involves excitation of baryons and that it is feasible to study their properties such as mass and total width. It is shown that under certain kinematical cuts the resonance signal can be isolated from the effect due to the final state interaction. Recent puzzles concerning the Σ-hyperon production are discussed.

While KamLAND provided a proof of concept for long distance antineutrino detection, the feasibility of detecting single reactors at distances greater than 100 km has not yet been established. Even larger detectors than KamLAND would be required for such a project. Considerations such as light attenuation, environmental impact and cost, which favor water as a detection medium, become more important as detectors get larger. We have studied both the sensitivity of water based detection media as a monitoring tool, and the scientific impact such detectors might provide. A next generation water based detector may be able to contribute to important questions in neutrino physics, such as supernova neutrinos, sterile neutrino oscillations, and non standard electroweak interactions (using a nearby compact accelerator source), while also providing a highly sensitive, and inherently unshieldable reactor monitoring tool to the non proliferation community. In this talk I will present the predicted performance of an experimental non proliferation and high-energy physics program.
