Using Sensor Graphs for Monitoring the Effect on the Performance of the OTAGO Exercise Program in Older Adults

The OTAGO exercise programme is effective in decreasing the risk for falls of older adults. This research investigated if there is an indication that the OTAGO exercise programme has a positive effect on the capacity and as well as on the performance in mobility. We used the data of the 10-months observational OTAGO pilot study with 15 (m = 1, f = 14) (pre-)frail participants aged 84.60 y (SD: 5.57 y). Motion sensors were installed in the flats of the participants and used to monitor their activity as a surrogate variable for performance. We derived a weighted directed multigraph from the physical sensor network, subtracted the weights of one day from a baseline, and used the difference in percent to quantify the change in performance. Least squares was used to compute the overall progress of the intervention (n = 9) and the control group (n = 6). In accordance with previous studies, we found indication for a positive effect of the OTAGO program on the capacity in both groups. Moreover, we found indication that the OTAGO program reduces the decline in performance of older adults in daily living. However, it is too early to conclude causalities from our findings because the data was collected during a pilot study.

Feasibility of an individualised, task-oriented, video-supported home exercise programme for arm function in patients in the subacute phase after stroke: protocol of a randomised controlled pilot study

IntroductionStroke rehabilitation guidelines suggest a high-frequency task-oriented training at high intensity. A targeted and self-paced daily training with intermittent supervision is recommended to improve patients’ self-management and functional output. So far, there is conflicting evidence concerning the most effective home-training delivery method.Methods and analysisThe purpose of this pilot study is to compare the feasibility and preliminary effects of task-oriented home-exercises in patients in the subacute stage after stroke. Twenty-four patients will be randomised (1:1) to a Video group (a) or Paper group (b) of an individualised, task-oriented home-training (50 min, 6×/week, for 4 weeks) based on Wulf and Lewthwaite’s Optimizing Performance Through Intrinsic Motivation and Attention for Learning theory of motor learning. Patient-relevant goals will be identified using Goal Attainment Scaling and exercises progressively adapted. Semistructured interviews and a logbook will be used to monitor adherence, arm use and acceptability. Primary outcome will be the feasibility of the methods and a full-scale trial employing predefined feasibility criteria (recruitment, retention and adherence rates, patients’ satisfaction with the home-exercise programme and their progress, affected hand use and acceptance of the intervention). Assessed at baseline, post intervention and 4-week follow-up, secondary outcomes include self-perceived hand and arm use, actual upper extremity function and dexterity, hand strength, independence in activities of daily living and health-related quality of life. Interview data will be analysed using qualitative content analysis. Medians (ranges) will be reported for ordinal data, means (SD) for continuous and frequency (percentage) for nominal data.Ethics and disseminationThis study follows the Standard Protocol Items: Recommendations for Interventional Trials-Patient-Reported Outcome (PRO) Extension guideline. Ethical approval was received from the Ethics Committee of the Medical University of Innsbruck, Austria (1304/2020). Written informed consent will be obtained from all participants prior to data collection. Study results will be disseminated to participating patients, patient organisations, via the clinic’s homepage, relevant conferences and peer-reviewed journals.Trial registration numberDRKS-ID: DRKS00023395.Study protocol, second revision, 5 December 2021.

Older Adults’ Experience of an Exergaming Intervention to Improve Balance and Prevent Falls: A Nested Explanatory Qualitative Study

Falls are frequent and life-changing events for older adults worldwide. The ageing phenomenon has arrived in developing countries, which experience tensions between curative and rehabilitative services, combined with an increase in non-communicable diseases. Policies addressing issues of ageing have been poorly implemented, and there are few fall prevention initiatives. Compelling evidence from the Global North supports exercise-based interventions to improve balance and reduce fall risk in older adults. More recently, attention has focused on interactive videogaming, known as exergames, as a novel way to manage fall risk with exercise. Commercially available exergames have inherent appeal for low- and middle-income country contexts, where rehabilitation professionals and resources are scanty. The aim of this study was to explore the feasibility of a large-scale randomized control trial comparing an exergaming intervention with the gold-standard Otago Exercise Programme and a no-intervention arm. Exercise adherence was poor in both intervention arms, and this prompted a shift to mixed methodology to explore the construct of falls and participants’ experience of the exergaming intervention. Focus groups were conducted, and the results were analysed using content analysis. Whereas the results demonstrated improvements in physical outcome measures (e.g., Timed-Up-and-Go, MiniBESTest) related to balance and falls that were encouraging in both the gold-standard and exergaming intervention groups, few participants achieved optimal adherence. Attitudes toward falls and fall prevention were explored, as well as participants’ experiences of the exergaming programme. Consistent with a developing country context, participants acknowledged both intrinsic and extrinsic fall risk factors. Exergaming participants enjoyed the fun and playful aspects of the exercise programme, yet these were not sufficient to maximize adherence. The focus groups described the barriers and facilitators to participation, which included motivation. The focus groups discussed strategies to enhance participation, and these are discussed in the context of exergaming.

Development of an exercise programme for balance abilities in people with multiple sclerosis: a development of concept study using Rasch analysis

Background People with multiple sclerosis (PwMS) frequently have impaired balance from an early stage of the disease. Balance difficulties can be divided into categories; although, to date, these lack scientific foundation. Impaired balance in PwMS can be addressed using specific and challenging exercises. Such exercises should provide an optimal challenge point; however, the difficulty of balance exercises is often unknown, making it difficult to target the exercises to an individual’s abilities. The aims of this study were: to develop an exercise programme for PwMS relating the exercises to the balance problem categories; to establish the order of difficulty of exercises in each category and; to evaluate the content and structural validity of the exercise programme. Methods A “construct map” approach was used to design and develop an exercise programme for PwMS. Potentially relevant balance exercises were identified, then a framework was set up, comprising four dimensions (subsequently reduced to three dimensions) of balance exercises. The relevance, comprehensibility, and comprehensiveness of the exercise programme were rated by 13 physiotherapists, who also linked 19 key exercises to balance categories. A total of 65 PwMS performed the 19 balance exercises, rated their difficulty and commented on the relevance and comprehensibility of each exercise. A Rasch model was used to evaluate the relative difficulty of the exercises. To assess fit of the data to the Rasch model a rating scale model was used, which is a unidimensional latent trait model for polytomous item responses. Results Evaluation by the physiotherapists and PwMS indicated that the content validity of the exercise programme was adequate. Rasch analysis showed that the latent trait “balance exercises in PwMS” comprised three subdimensions (“stable BOS”, “sway” and “step and walk”). The 19 balance exercises showed adequate fit to the respective dimensions. The difficulties of the balance exercises were adequate to cover the ability spectrum of the PwMS. Conclusion A balance exercise programme for PwMS comprising three dimensions of balance exercises was developed. Difficulty estimates have been established for each of the exercises, which can be used for targeted balance training. Content and structural validity of the programme was adequate.
