Background: Adults with intellectual disability (ID) have a higher rate of fall events than the general population. Consequently, interventions for reducing fall events and improving health are highly required for individuals with ID. One essential step towards effectively delivering fall prevention interventions among adults with ID involves evaluating their feasibility. This study examined the feasibility of a home‐based exercise intervention, supplemented with behavioural change strategies, among individuals with ID living in residential settings. Method: This study provided an 8‐week intervention, consisting of a workshop for support workers and sessions for participants with ID, focusing on behavioural reward/s, education regarding fall prevention/exercise and exercise training. One week prior to and 1 week following such an intervention, such participants underwent measurements for (1) physical performance, (2) fall efficacy, (3) self‐efficacy for activity and (4) social support. Results: Participants having ID (n = 33), support workers (n = 11) and one administrator participated in this study. There were no adverse events during the intervention, and the mean adherence rate was 70.8 ± 19.5%. Two participants with ID dropped out of the programme due to a lack of interest. The participants with ID significantly improved individual physical performance, self‐efficacy for activity, fall efficacy and support from friends and support workers. Conclusions: Fall prevention interventions for adults with ID living in group‐homes were highly promising for eventual large‐scale implementation within such communities. [ABSTRACT FROM AUTHOR]

Background: The knowledge base on physical activity and sedentary behaviour in adults with Down syndrome (DS) may advance by accelerometer calibration studies. This study aimed to develop cut‐points for sedentary behaviour and moderate‐to‐vigorous physical activity (MVPA) for adults with DS based on output from accelerometers worn on the dominant and non‐dominant hips. Methods: Sixteen adults with DS (10 men; age 31 ± 15 years) performed 12 tasks including sedentary behaviours and physical activities. We obtained metabolic equivalents (METs) with indirect calorimetry and vector magnitude (VM) output from triaxial accelerometers (wGT3X‐BT, ActiGraph) worn on the dominant and non‐dominant hips. Receiver operating characteristic curves were used to identify optimal VM cut‐points that maximised sensitivity and specificity. Results: Overall classification accuracy was very high (area under the ROC curve: 0.95 and 0.92 for sedentary and MVPA models, respectively). For the non‐dominant hip, the optimal VM cut‐points were (1) sedentary behaviour ≤236 counts·min−1 and (2) MVPA ≥2167 counts·min−1. For the dominant hip, optimal cut‐points were (1) sedentary behaviour ≤243 counts·min−1 and (2) MVPA ≥2092 counts·min−1. Conclusions: The presented VM cut‐points for sedentary behaviour and MVPA for adults with DS had high classification accuracy. There were small differences in accelerometer cut‐points between the dominant and non‐dominant hip. [ABSTRACT FROM AUTHOR]

Background: Limited data exist on the prevalence and distribution of sedentary behavior (SB) in multiple sclerosis (MS). Objective: The objective of this paper is to describe sitting time as a metric of SB in a large national sample of people with MS. Methods: A total of 8004 individuals from the North American Research Committee on MS (NARCOMS) Registry completed the sitting time question from the International Physical Activity Questionnaire in spring 2015. We present descriptive data on sitting time for the total sample and across sociodemographic, clinical, and behavioral characteristics. Results: The final sample included 6483 individuals. Of these, 36.7% were classified with mild disability, 24.7% with moderate disability, and 38.6% with severe disability. Median sitting time for the total sample was 480 min/day (P25 = 310 min/day, P75 = 720 min/day). Sitting time was highest for individuals with MS who were male (540 min/day), not married (540 min/day), had a disease duration >30 years (540 min/day), were underweight (540.5 min/day), had an annual income of <$15,000 (585 min/day), presented with a progressive form of MS (600 min/day), were classified as insufficiently active (600 min/day), or presented with severe disability (661 min/day). Conclusion: Sitting time is twice as high in individuals with MS compared to the general population (240 min/day). [ABSTRACT FROM AUTHOR]

Objectives: Multiple sclerosis (MS) is a neurological disease that commonly results in physical and cognitive dysfunction. Accordingly, MS might impact the ability to safely cross the street. The purpose of this study was to examine the feasibility of a simulated street-crossing task in persons with MS and to determine differences in street-crossing performance between persons with MS and non-MS controls.Methods: 26 participants with MS (median Expanded Disability Status Scale [EDSS] score = 3.5) and 19 controls completed 40 trials of a virtual street-crossing task. There were 2 crossing conditions (i.e., no distraction and phone conversation), and participants performed 20 trials per condition. Participants were instructed that the goal of the task was to cross the street successfully (i.e., without being hit be a vehicle). The primary outcome was task feasibility, assessed as completion and adverse events. Secondary outcomes were measures of street-crossing performance.Results: Overall, the simulated street-crossing task was feasible (i.e., 90% completion, no adverse events) in participants with MS. Participants with MS waited longer and were less attentive to traffic before entering the street compared with controls (all P < .05). Participants with MS also took longer to cross the street and were closer to oncoming vehicles when exiting the street compared to controls (all P < .05). When distracted, all participants took longer to initiate crossing, took longer to cross the street, and made more head turns while crossing (all P < .05). There were no significant group by condition interaction effects (all P > .05).Conclusions: A virtual street-crossing task is feasible for studying street-crossing behavior in persons with mild MS and most individuals with moderate MS. Virtual street-crossing performance is impaired in persons with MS compared to controls; however, persons with MS do not appear to be more vulnerable to a distracting condition. The virtual reality environment presents a safe and useful setting for understanding pedestrian behavior in persons with MS. [ABSTRACT FROM AUTHOR]
