The effects of exergaming on balance, gait, technology acceptance and flow experience in people with multiple sclerosis: a randomized controlled trial

Effectiveness of Nintendo Wii Fit© for Physical Therapy in Patients with Multiple Sclerosis: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Multiple sclerosis (MS) is a chronic, inflammatory, and autoimmune disease that mainly affects the central nervous system and currently has no cure. Exergaming is considered a non-immersive approach to improving functional and motor skills in the treatment of MS. The aim of this systematic review was to evaluate the effectiveness of the Nintendo Wii Fit© (NWF) on physical outcomes compared with control regimes in patients with MS. The search was performed in seven databases including articles published up to June 2024. The PICOS model was used to establish the study eligibility criteria. The Cochrane Collaboration tool and the PEDro scale were used to assess the risk of bias and evaluate the methodological quality of the studies, respectively. A meta-analysis using the standardized mean difference (SMD) and confidence interval (95% CI) was developed using the Review Manager 5.4 software. Seven articles were included in the systematic review. The statistical analysis showed favorable overall results for the NWF on functional mobility (SMD = 0.25; 95% CI = 0.09, 0.41) and fatigue (SMD = 0.41; 95% CI = 0.00, 0.82). In conclusion, this systematic review suggests that the NWF has shown favorable effects compared to control regimes on functional mobility and fatigue outcomes in patients with MS.

Home-Based Balance Training on Balance and Mobility in Persons With Multiple Sclerosis: A Systematic Review and Meta-analysis

OBJECTIVES

To (1) examine the effects of home-based balance training on balance and mobility outcomes; (2) evaluate comparable effects between home- and center-based balance training; (3) determine the effects of different levels of supervision on treatment effects; and (4) investigate dose-response relationships of home-based balance training on balance and mobility performance in persons with multiple sclerosis (MS).

DATA SOURCES

Literature searches were conducted in MEDLINE, EMBASE, PsycINFO, SPORTSDiscus, and CINAHL in April 2023. Other literature sources included website and citation searches.

STUDY SELECTION

The study included randomized controlled trials of home-based balance training that included balance and mobility outcomes in persons with MS.

DATA EXTRACTION

Data extracted from each study included (1) number of participants; (2) dropout rate; (3) sex; (4) MS phenotype; (5) age; (6) Expanded Disability Status Scale (range); (7) exercise dose; (8) level of supervision; (9) type of intervention; (10) exercise progression; (11) type of control; and (12) outcomes measures. For the meta-analysis, mean and SD of the balance and mobility outcomes in both the intervention and control groups were used. The methodological quality of included studies was evaluated by Tool for the Assessment of Study Quality and Reporting in Exercise.

DATA SYNTHESIS

Eleven studies were identified in this systematic review and meta-analysis. Each balance and mobility outcome was standardized using Hedges' g.

CONCLUSIONS

This meta-analysis revealed comparable results between home- and center-based balance training in terms of balance and mobility improvement. There was also no evidence for the superiority of home-based balance training over no training except for static steady-state balance. This study revealed that training sessions (>36 sessions) and total exercise time (>1100min) were significant moderators for overall balance improvements. Results also indicated that, when designing future interventions, at least an indirect level of supervision (eg, weekly or biweekly phone/video calls) is warranted to maintain adherence.

Scientometric Research and Critical Analysis of Gait and Balance in Older Adults

Gait and balance have emerged as a critical area of research in health technology. Gait and balance studies have been affected by the researchers' slow follow-up of research advances due to the absence of visual inspection of the study literature across decades. This study uses advanced search methods to analyse the literature on gait and balance in older adults from 1993 to 2022 in the Web of Science (WoS) database to gain a better understanding of the current status and trends in the field for the first time. The study analysed 4484 academic publications including journal articles and conference proceedings on gait and balance in older adults. Bibliometric analysis methods were applied to examine the publication year, number of publications, discipline distribution, journal distribution, research institutions, application fields, test methods, analysis theories, and influencing factors in the field of gait and balance. The results indicate that the publication of relevant research documents has been steadily increasing from 1993 to 2022. The United States (US) exhibits the highest number of publications with 1742 articles. The keyword "elderly person" exhibits a strong citation burst strength of 18.04, indicating a significant focus on research related to the health of older adults. With a burst factor of 20.46, Harvard University has made impressive strides in the subject. The University of Pittsburgh displayed high research skills in the area of gait and balance with a burst factor of 7.7 and a publication count of 103. The research on gait and balance mainly focuses on physical performance evaluation approaches, and the primary study methods include experimental investigations, computational modelling, and observational studies. The field of gait and balance research is increasingly intertwined with computer science and artificial intelligence (AI), paving the way for intelligent monitoring of gait and balance in the elderly. Moving forward, the future of gait and balance research is anticipated to highlight the importance of multidisciplinary collaboration, intelligence-driven approaches, and advanced visualization techniques.

Effects of exercise in people with multiple sclerosis: a systematic review and meta-analysis

Background

A growing body of studies have examined the effect of exercise in people with multiple sclerosis (MS), while findings of available studies were conflicting. This meta-analysis aimed to explore the effects of exercise on balance, walking ability, walking endurance, fatigue, and quality of life in people with MS.

Methods

We searched PubMed, Web of Science, Scopus, and Cochrane databases, through March 1, 2024. Inclusion criteria were: (1) RCTs; (2) included an intervention and control group; (3) had people with MS as study subjects; (4) had balance, walking ability, walking endurance, fatigue, or quality of life as the outcome measures. Exclusion criteria were: (1) non-English publications; (2) animal model publications; (3) review articles; and (4) conference articles. A meta-analysis was conducted to calculate weighted mean difference (WMD) and 95% confidence interval (CI). Cochrane risk assessment tool and Physiotherapy Evidence Database (PEDro) scale were used to evaluate the methodological quality of the included studies.

Results

Forty studies with a total of 56 exercise groups (n = 1,300) and 40 control groups (n = 827) were eligible for meta-analysis. Exercise significantly improved BBS (WMD, 3.77; 95% CI, 3.01 to 4.53, P < 0.00001), TUG (WMD, -1.33; 95% CI, -1.57 to -1.08, P < 0.00001), MSWS-12 (WMD, -2.57; 95% CI, -3.99 to -1.15, P = 0.0004), 6MWT (WMD, 25.56; 95% CI, 16.34 to 34.79, P < 0.00001), fatigue (WMD, -4.34; 95% CI, -5.83 to -2.84, P < 0.00001), and MSQOL-54 in people with MS (WMD, 11.80; 95% CI, 5.70 to 17.90, P = 0.0002) in people with MS. Subgroup analyses showed that aerobic exercise, resistance exercise, and multicomponent training were all effective in improving fatigue in people with MS, with resistance exercise being the most effective intervention type. In addition, a younger age was associated with a larger improvement in fatigue. Furthermore, aerobic exercise and multicomponent training were all effective in improving quality of life in people with MS, with aerobic exercise being the most effective intervention type.

Conclusion

Exercise had beneficial effects in improving balance, walking ability, walking endurance, fatigue, and quality of life in people with MS. Resistance exercise and aerobic exercise are the most effective interventions for improving fatigue and quality of life in people with MS, respectively. The effect of exercise on improving fatigue was associated with the age of the participants, with the younger age of the participants, the greater the improvement in fatigue.

The Flow State Scale for Rehabilitation Tasks: A New Flow Experience Questionnaire for Stroke Patients

IMPORTANCE

Flow can be described as a subjective state that people report when they fully engage in an activity and experience pleasure, satisfaction, and enjoyment. Flow experiences are measured to determine the extent to which patients engage in therapy activities. Several flow questionnaires are used in neurorehabilitation. However, none have been validated for patients with (sub)acute stroke.

OBJECTIVE

To develop and validate a new flow questionnaire for patients with (sub)acute stroke.

DESIGN

Single-center prospective cohort study.

SETTING

Neurorehabilitation unit of the Neurocenter of the Luzerner Kantonsspital in Lucerne, Switzerland.

PARTICIPANTS

Fifty patients with (sub)acute stroke.

OUTCOMES AND MEASURES

Development of the Flow State Scale for Rehabilitation Tasks (FSSRT) and determination of the psychometric properties of the FSSRT (internal consistency, test-retest reliability, structural and construct validity) in (sub)acute stroke patients.

RESULTS

The FSSRT showed good internal consistency and excellent test-retest reliability. Composed of four components-concentration, pleasure, movement control, and absorption-the FSSRT correlated significantly negatively with the Hospital Anxiety and Depression Scale, indicating good divergent validity.

CONCLUSIONS AND RELEVANCE

The FSSRT is a reliable and valid questionnaire measuring flow experience in patients with (sub)acute stroke. This questionnaire can be easily used in occupational therapy as well as in physical therapy and gives therapists important information about the flow experience of patients during therapy to adjust the therapy accordingly. Plain-Language Summary: Measuring flow experience, or the extent to which patients engage in therapy activities, in the context of occupational therapy and physical therapy is a new approach. This study confirmed that the Flow State Scale for Rehabilitation Tasks questionnaire is reliable and valid for measuring the flow experience of patients after (sub)acute stroke. Occupational therapists and physical therapists can use the FSSRT to optimally adjust the therapy program and increase patient engagement during therapy.

Exercise-based gaming in patients with multiple sclerosis: A systematic review and meta-analysis

Background

Multiple sclerosis presents a significant burden, with balance disturbances impacting patients' daily living. Conventional therapies have been supplemented with technological advancements like virtual reality (VR) and exergaming, providing engaging, multisensory rehabilitation options.

Objective

This study aimed to synthesize evidence on exergaming's role in multiple sclerosis treatment, particularly to evaluate the impact of exergaming on cognitive, motor, and psychological outcomes in patients with multiple sclerosis.

Methods

A systematic review and subsequent meta-analysis design were employed. An extensive search was conducted up to June 2023 across five electronic databases - Web of Science, Scopus, PubMed, Cochrane, and EMBASE. The data extraction process from the selected studies was conducted independently. The risk of bias was assessed using the Cochrane Risk of Bias Assessment Tool 1 (ROB1) and the National Institutes of Health (NIH) assessment tool. Continuous outcomes were consolidated as mean differences (MD) with 95% confidence intervals (CIs). Meta-analyses were performed using RevMan ver. 5.4.

Results

Out of 1,029 studies, 27 were included for meta-analysis. There were no significant differences in cognitive outcomes between the exergaming and the no-intervention group or the Conventional Physiotherapy and Rehabilitation interventions (CPRh) subgroups. However, the Symbol Digit Modalities Test (SDMT) showed a statistically significant difference in favor of exergaming in the no-intervention subgroup (MD = 5.40, 95% CI [0.08, 10.72], p = 0.05). In motor outcomes, exergaming only demonstrated better results in the 6-minute walking test compared to the no-intervention group (MD = 25.53, 95% CI [6.87, 44.19], p = 0.007). The Berg Balance Scale score in both studied subgroups and the Timed Up and Go (TUG) test in the no-intervention group favored exergaming. In terms of psychological outcomes, the Beck Depression Inventory did not reveal any significant differences, while the Modified Fatigue Impact Scale (MFIS) score favored exergaming in the CPRh subgroup.

Conclusion

Exergaming shows promise for enhancing cognitive and motor functions, motivation, adherence, and quality of life in MS patients, which is beneficial for nurses. It can be tailored to individual preferences and easily conducted at home, potentially serving as a viable alternative to traditional rehab programs, especially during relapses. However, further research is necessary to fully understand its optimal and lasting benefits.

Assessment of Postural Control in Children with Movement Disorders by Means of a New Technological Tool: A Pilot Study

Considering the variability and heterogeneity of motor impairment in children with Movement Disorders (MDs), the assessment of postural control becomes essential. For its assessment, only a few tools objectively quantify and recognize the difference among children with MDs. In this study, we use the Virtual Reality Rehabilitation System (VRRS) for assessing the postural control in children with MD. Furthermore, 16 children (mean age 10.68 ± 3.62 years, range 4.29-18.22 years) were tested with VRRS by using a stabilometric balance platform. Postural parameters, related to the movements of the Centre of Pressure (COP), were collected and analyzed. Three different MD groups were identified according to the prevalent MD: dystonia, chorea and chorea-dystonia. Statistical analyses tested the differences among MD groups in the VRRS-derived COP variables. The mean distance, root mean square, excursion, velocity and frequency values of the dystonia group showed significant differences (p < 0.05) between the chorea group and the chorea-dystonia group. Technology provides quantitative data to support clinical assessment: in this case, the VRRS detected differences among the MD patterns, identifying specific group features. This tool could be useful also for monitoring the longitudinal trajectories and detecting post-treatment changes.

Effects of non-pharmacological interventions on gait and balance of persons with Multiple Sclerosis: A narrative review

BACKGROUND

Multiple Sclerosis (MS) is among the most common reasons for disability in young adults. Mobility impairment, primarily related to gait and balance, is ranked as the preeminent concern among persons with MS (PwMS). Gait and balance dysfunction can directly affect the quality of life and activities of daily life in PwMS, hence the importance of effective treatment strategies. Previous studies have demonstrated the positive effect of various non-pharmacological rehabilitation methods, including physiotherapy and electrical stimulation, on gait and mobility in PwMS. Non-pharmacological methods can be tailored to the individual needs and abilities of each patient, allowing healthcare providers to create personalized training programs. Furthermore, these methods typically result in minimal or no side effects.

PURPOSE

This review provides a comprehensive overview of an array of non-pharmacological treatment approaches aimed at enhancing ambulatory performance in PwMS.

METHODS

We performed a narrative review of the original papers available in PubMed, investigating the effects of different nonmedical approaches on the gait and balance performance of the PwMS. Reviewed treatment approaches include "exercise, physical rehabilitation, dual-task (DT) rehabilitation, robot-assisted rehabilitation, virtual reality-assisted rehabilitation, game training, electrical stimulation devices, auditory stimulation, visual feedback, and shoe insoles".

RESULTS AND CONCLUSIONS

Eighty articles were meticulously reviewed. Our study highlights the positive effects of non-pharmacological interventions on patients' quality of life, reducing disability, fatigue, and muscle spasticity. While some methods, including exercise and physiotherapy, showed substantial promise, further research is needed to evaluate whether visual biofeedback and auditory stimulation are preferable over conventional approaches. Additionally, approaches such as functional electrical stimulation, non-invasive brain stimulation, and shoe insoles demonstrate substantial short-term benefits, prompting further investigation into their long-term effects. Non-pharmacological interventions can serve as a valuable complement to medication-based approaches.

Use of Virtual Reality in Physical Therapy as an Intervention and Diagnostic Tool

Within the past decade, the integration of computer-generated virtual realities (VRs) has witnessed a significant rise in the field of healthcare, particularly in diagnosis and treatment applications. These VR systems have found extensive use in physical therapy, rehabilitation, research, and assessment. This narrative review article is aimed at providing a comprehensive overview of the literature regarding the implementation of VR in the physical therapy profession. The primary objective of this review is to provide information to clinicians about the diverse applications of VR and its potential advantages in intervening across various patient populations and diagnoses during rehabilitation therapy. Through in-depth discussions with experts and a thorough review of pertinent literature, several significant aspects of the topic were identified. Subsequently, we carried out an online search to investigate the prevalent utilization of VR systems within healthcare, both as assessment tools and for therapeutic interventions. Our examination encompassed a total of 56 articles, with supplementary references incorporated as required.

Comparing virtual reality exergaming with conventional exercise in rehabilitation of people with multiple sclerosis: A systematic review

This systematic review aimed to present the comparison of the impacts of conventional exercise and virtual reality (VR) exergaming on the physical and cognitive abilities of people with multiple sclerosis (PwMS). The literature search was conducted in the EMBASE, PubMed, Scopus, CINAHL, and Cochrane Library databases. Eligible studies were identified by independent reviewers based on the title, abstract and full-texts. Studies were limited to randomized clinical trials published in peer-reviewed journals in English that compared conventional exercise with VR-exergaming for improving the physical and cognitive abilities of PwMS. Selected studies were assessed for their risk of bias and the major findings of the reviewed studies were analyzed descriptively. The search identified 239 articles of which 10 studies met the eligibility criteria. Despite these studies employing strategies to control biases, some risks of bias remain. Various gaming platforms and conventional exercises were used based on the extent of technologies and therapy regimens. The selected studies used measures of physical and cognitive abilities to compare VR-exergaming with conventional exercise. This review suggests positive impacts of both VR-exergaming and conventional exercise in MS rehabilitation. We also found that VR-exergaming generally exceeded conventional exercise for improving physical and cognitive abilities, psychosocial status, and fatigue.

Therapy-based expert system on function and postural stability after anterior cruciate ligament reconstruction: a pilot study

PURPOSE

Wii Fit exergames have been less commonly used for the rehabilitation of athletes after Anterior Cruciate Ligament Reconstruction (ACLR). This study aims to investigate the effects of an expert system using Wii Fit exergames compared to conventional rehabilitation following ACLR. A forward-chaining rule-based expert system was developed which proposed a rehabilitation program that included the number and type of exercise in terms of difficulty and ease and the duration of each exercise in a progressive manner according to the patient's physical condition.

MATERIALS AND METHODS

Twenty eligible athletes aged 20-30 who underwent ACLR were enrolled in this study and randomly assigned to two groups; and received 12 sessions of either Wii Fit exergames as Wii group (n = 10) or conventional rehabilitation as CL group (n = 10).

RESULTS

The main outcomes consisted of pain (Visual Analogue Scale (VAS)), knee effusion, knee flexion range (KFR), thigh girth (TG), single-leg hop for distance (SLHD), and for time (SLHT), static and dynamic balance tests. Both groups had considerable improvement in all outcomes, also there were significantly differences between Wii and CL groups as follows; VAS (P < 0.001), knee effusion (P < 0.001), TG (P = 0.001), KFR (P = 0.012), static balance in stable position (P < 0.001) and in unstable position (P = 0.001), dynamic balance in the anterior (P < 0.001), posteromedial (P < 0.001), posterolateral (P = 0.004) directions, symmetry index of SLHD (P < 0.001) and symmetry index of SLHT (P = 0.013).

CONCLUSIONS

The findings showed that using Wii Fit exergames in post-ACLR patients reduced pain and effusion while also improving function and balance significantly. Iranian Registry of Clinical Trials registration number is IRCT20191013045090N1, and the registration date is 03-03-2020.

Virtual reality-based therapy improves balance and reduces fear of falling in patients with multiple sclerosis. a systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

This study aims to conduct a meta-analysis to assess the effect of virtual reality-based therapy (VRBT) on balance dimensions and fear of falling in patients with multiple sclerosis (PwMS). Secondarily, to determine the most recommendable dose of VRBT to improve balance.

METHODS

PubMed Medline, Web of Science, Scopus, CINAHL and PEDro were screened, without publication date restrictions, until September 30th, 2021. Randomized controlled trials (RCTs) comparing the effectiveness of VRBT against other interventions in PwMS were included. Functional and dynamic balance, confidence of balance, postural control in posturography, fear of falling and gait speed were the variables assessed. A meta-analysis was performed by pooling the Cohen's standardized mean difference (SMD) with 95% confidence interval (95% CI) using Comprehensive Meta-Analysis 3.0.

RESULTS

Nineteen RCTs, reporting 858 PwMS, were included. Our findings reported that VRBT is effective in improving functional balance (SMD = 0.8; 95%CI 0.47 to 1.14; p < 0.001); dynamic balance (SMD = - 0.3; 95%CI - 0.48 to - 0.11; p = 0.002); postural control with posturography (SMD = - 0.54; 95%CI - 0.99 to - 0.1; p = 0.017); confidence of balance (SMD = 0.43; 95%CI 0.15 to 0.71; p = 0.003); and in reducing fear of falling (SMD = - 1.04; 95%CI - 2 to - 0.07; p = 0.035); but not on gait speed (SMD = - 0.11; 95%CI: - 0.35 to 0.14; p = 0.4). Besides, the most adequate dose of VRBT to achieve the greatest improvement in functional balance was at least 40 sessions, five sessions per week and 40-45 min per sessions; and for dynamic balance, it would be between 8 and 19 weeks, twice a week and 20-30 min per session.

CONCLUSION

VRBT may have a short-term beneficial role in improving balance and reducing fear of falling in PwMS.

Unwrapping the "black box" of balance training in people with multiple sclerosis - A descriptive systematic review of intervention components, progression, and intensity

BACKGROUND

Delineating the specific components of the existing balance training interventions in people with multiple sclerosis (PwMS) may contribute to a framework for future design and reporting of such interventions. Thus, we aimed to systematically synthesize how balance training frequency, intensity, time, type, duration, and progression are reported in balance training interventions for PwMS.

METHODS

A systematic literature search was conducted in Medline, Embase, Web of Science, and Cinahl. Search terms were MS, postural balance, walking, gait, and randomized/quasi-randomized controlled or clinical trials. Articles including ambulatory PwMS and interventions designed to challenge the balance control system were eligible. Two investigators screened, selected, and extracted data independently. Data on study characteristics such as design, population, and balance training content were extracted. Categorization of balance training based on balance control components was performed.

RESULTS

We included 40 studies grouped under five balance training categories. Balance interventions were well described regarding frequency, session time, and duration, but only two interventions described training intensity, and no systematic, gradual progression approach was reported for balance training adaptation over time. However, the balance training interventions included many sensory and motor components of the balance control system. Still, little focus was on reactive motor strategies, vestibular sense, and cognitive dual-tasking.

CONCLUSIONS

Existing balance training interventions in PwMS primarily consist of practicing sensory and motor strategies. Future balance training interventions are encouraged to systematically monitor individual advancements in balance training adaptations and to apply the progressive overload principle (i.e. continuous increase in balance exercise stimulus over time). Furthermore, we suggest that balance training in PwMS is performed with high intensity near an individual's balance capacity limits. Finally, individualized balance training is recommended to cover all relevant components of balance control using the proposed framework.

Mobility and balance rehabilitation in multiple sclerosis: A systematic review and dose-response meta-analysis

OBJECTIVE

To assess the benefits of neurological rehabilitation and the dose-response relationship for the treatment of mobility and balance in multiple sclerosis.

METHODS

We included studies investigating the effects of neurological rehabilitation on mobility and balance with the following eligibility criteria for inclusion: Population, People with Multiple Sclerosis (PwMS); Intervention, method of rehabilitation interventions; Comparison, experimental (specific balance intervention) vs control (no intervention/no specific balance intervention); Outcome, balance clinical scales; Study Design, randomised controlled trials. We conducted a random effects dose-response meta-analysis to assess linear trend estimations and a one stage linear mixed effects meta-regression for estimating dose-response curves.

RESULTS

We retrieved 196 studies from a list of 5020 for full text review and 71 studies (n subjects=3306) were included. One study was a cross-over and 70 studies were randomized controlled trials and the mean sample size per study was 46.5 ± 28.6 (mean±SD) with a mean age of 48.3 ± 7.8years, disease duration of 11.6 ± 6.1years, and EDSS of 4.4 ± 1.4points. Twenty-nine studies (40.8%) had the balance outcome as the primary outcome, while 42 studies (59.1%) had balance as secondary outcome or did not specify primary and secondary outcomes. Thirty-three trials (46.5%) had no active intervention as comparator and 38 trials (53.5%) had an active control group. Individual level data from 20 studies (n subjects=1016) were analyzed showing a medium pooled effect size for balance interventions (SMD=0.41; 95% CIs 0.22 to 0.59). Moreover, we analyzed 14 studies (n subjects=696) having balance as primary outcome and BBS as primary endpoint yielding a mean difference of 3.58 points (95% CIs 1.79 to 5.38, p<0.0001). Finally, we performed meta regression of the 20 studies showing an association between better outcome, log of intensity defined as minutes per session (β=1.26; SEβ=0.51; p = 0.02) and task-oriented intervention (β=0.38; SEβ=0.17; p = 0.05).

CONCLUSION

Our analyses provide level 1 evidence on the effect of balance intervention to improve mobility. Furthermore, according to principles of neurological rehabilitation, high intensity and task-specific interventions are associated with better treatment outcomes.

Dropout rate in randomised controlled trials of balance and gait rehabilitation in multiple sclerosis: is it expected to be different for virtual reality-based interventions? A systematic review with meta-analysis and meta-regression

To assess and meta-analyse the pooled dropout rate from the randomised control trilas that use virtual reality for balance or gait rehabilitation in people with multiple sclerosis. A systematic review of randomised control trials with meta-analysis and meta-regressions was performed. A search was conducted in PubMed, Scopus, Web of Science, the Physiotherapy Evidence Database, the Cochrane Database, CINHAL, LILACS, ScienceDirect, and ProQuest. It was last updated in July 2022. After the selection of studies, a quality appraisal was carried out using the PEDro Scale and the Revised Cochrane risk-of-bias tool for randomised trials. A descriptive analysis of main characteristics and dropout information was performed. An overall proportion meta-analysis calculated the pooled dropout rate. Odds ratio meta-analysis compared the dropout likelihood between interventions. The meta-regression evaluated the influence of moderators related to dropout. Sixteen studies with 656 participants were included. The overall pooled dropout rate was 6.6% and 5.7% for virtual reality and 9.7% in control groups. The odds ratio (0.89, p = 0.46) indicated no differences in the probability of dropouts between the interventions. The number, duration, frequency, and weeks of sessions, intervention, sex, multiple sclerosis phenotype, Expanded Disability Status Scale score, and PEDro score were not moderators (p > 0.05). Adverse events were not reported and could not be analysed as moderators. Dropouts across the virtual reality and control comparators were similar without significant differences. Nonetheless, there is a slight trend that could favour virtual reality. Standardisation in reporting dropouts and adverse events is recommended for future trials.

Participant characteristics of existing exercise studies in persons with multiple sclerosis - A systematic review identifying literature gaps

BACKGROUND

Exercise is a cornerstone in rehabilitation of persons with multiple sclerosis (pwMS), which is known to elicit beneficial effects on various symptoms and to have a potential disease-modifying effect. However, it remains to be elucidated if the existing MS exercise literature covers the full age and disability span of pwMS.

OBJECTIVE

To systematically review MS exercise studies and provide a detailed mapping of the demographic and clinical characteristics of the included pwMS.

METHODS

A systematic review of MS exercise studies were performed using MEDLINE and EMBASE. From the resulting MS exercise studies, mean sample characteristics were extracted.

RESULTS

4576 records were identified, from which 202 studies were included. Of these, 166 studies (82.2%) enrolled pwMS aged 35-54 years, 10.9% enrolled pwMS <35 years, and 6.9% enrolled pwMS ≥55 years (only 1.5% enrolled pwMS ≥60 years). A total of 118 studies (58.4%) reported Expanded Disability Status Scale (EDSS), with 88.1% of included pwMS having an EDSS between 2.0 and 6.5, while only one study enrolled pwMS with an EDSS ≥7.0. Finally, 80% of the studies included pwMS having a disease duration of 5-14.5 years.

CONCLUSION

Exercise studies in pwMS included primarily middle-aged (35-54 years) pwMS having an EDSS of 2.0-6.5 and a disease duration of 5-14.5 years. Few exercise studies were identified in young and older pwMS, in pwMS with mild disability and severe disability, and in pwMS having shorter or longer disease durations. These findings highlight the need for further investigation of exercise in these specific subgroups of pwMS as benefits of exercise might not generalize across subpopulations.

Effect of virtual reality training on standing balance in individuals with incomplete spinal cord injury

Recovery of balance ability during standing is one of the primary and essential aims of rehabilitative programs in individuals with incomplete spinal cord injury (iSCI). A sample of ten participants (mean age: 35.7 years, range: 25-63 years) with traumatic or non-traumatic iSCI (AIS grade C or D) and were able to stand with or without the support of an assistive device for a minimum of 2 min were recruited from the rehabilitation department of the Indian Spinal Injuries Centre, New Delhi, India. The participants received Virtual Reality (VR) based balance training for one hour, three times a week for four weeks on the Nintendo Wii gaming console. Participants were assessed three times: pre-intervention, post-intervention and follow-up assessment for the total ellipse area (TEA), total sway perimeter (TSP), sway range (anterior-posterior/medio-lateral (AP/ML)) and limits of stability (LOS). At post-intervention assessment, significant increases in comparison with pre-intervention scores was found in LOS (P=0.00), TEA with eyes open (EO) (P=0.00) and eyes closed (EC) (P=0.00), TSP with EO (P=0.00) and EC (P=0.00), sway range in AP direction (SD-AP) with EO (P=0.01) and EC (P=0.02) and sway range in ML direction (SD-ML) with EO (P=0.02) and EC (P=0.01). At follow-up assessment, a significant improvement in comparison to post intervention scores was found in TEA measured both in EO (P=0.01) and EC conditions (P=0.02), TSP measured with EO (P=0.01) and SD-ML both with EO (P=0.04) and EC (P=0.01). No significant changes were found in LOS (P=0.89), TSP measured with EC (P=0.38) and SD-AP both with EO (P=0.50) and EC (P=1). However, significant improvement was seen on comparing follow-up assessment scores with pre-intervention scores for all variables, such as LOS (P=0.00), TEA in EO (P=0.00) and EC (P=0.00), TSP with EO (P=0.00) and EC (P=0.00), SD-AP with EO (P=0.01) and EC (P=0.02) and SD-ML with EO (P=0.01) and EC (P=0.00). VR-based balance training intervention was able to elicit improvements in balance ability and maintain it during follow-up despite a small training dosage suggesting that it is a promising intervention for standing balance rehabilitation among individuals with iSCI. The VR-based balance training challenges elements of balance, which physical therapists may want to consider when designing a comprehensive rehabilitation program.

Effectiveness of Virtual Reality on Balance and Risk of Falls in People with Multiple Sclerosis: A Systematic Review and Meta-Analysis

The aim of this study was to systematically review the scientific evidence related to the physiotherapy interventions in neurorehabilitation that utilize virtual reality (VR) for balance training and risk of falls in people with multiple sclerosis (MS). A search was conducted in Medline (PubMed), PEDro, and Google Scholar to identify all the relevant studies. Clinical trials assessing the effects of VR in people with MS were included. Risk of bias was evaluated using the Cochrane Risk of Bias Tool and PEDro scale. Qualitative analysis was performed according to the GRADE. In total, 16 studies (n = 663) were included. The meta-analysis showed statistically significant differences for the VR intervention in comparison with conventional treatment for balance, with a moderate clinical effect in eight studies (SMD: 0.63; 95% CI 0.34-0.92; p < 0.05). In addition, the meta-analysis showed statistically significant differences for the VR intervention in comparison with conventional treatment for risk of falls, with a small clinical effect in six studies (SMD: -0.55; 95% CI -1.07-0.04; p < 0.05). VR-based treatments are more effective than non-intervention in improving balance and fall risk in people with MS, with a very low certainty of evidence. In addition, they also show to be more effective than conventional rehabilitation, with a very low certainty of evidence.

The Effectiveness of Physiotherapy Interventions for Mobility in Severe Multiple Sclerosis: A Systematic Review and Meta-Analysis

Background

People with Multiple Sclerosis (pwMS) prioritise gait as the most valuable function to be affected by MS. Physiotherapy plays a key role in managing gait impairment in MS. There is little evidence on the effectiveness of physiotherapy for severe MS.

Objective

To undertake a systematic review and meta-analysis of the literature to identify evidence for the effectiveness of physiotherapy for gait impairment in severe MS. Methods. The available literature was systematically searched, using a predetermined protocol, to identify research studies investigating a physiotherapy intervention for mobility in people with severe MS (EDSS ≥ 6.0). Data on mobility related endpoints was extracted. Meta-analysis was performed where a given mobility end point was reported in at least 3 studies.

Results

37 relevant papers were identified, which included 788 pwMS. Seven mobility-related endpoints were meta-analysed. Robot-Assisted Gait Training (RAGT) was found to improve performance on the 6-minute walk test, 10-metre walk test, fatigue severity scale, and Berg Balance Scale. Neither body weight supported training nor conventional walking training significantly improved any mobility-related outcomes.

Conclusion

Physiotherapy interventions are feasible for mobility in severe MS. There is some evidence for the effectiveness of RAGT.

Brain M-App’s Structure and Usability: A New Application for Cognitive Rehabilitation at Home

Cognitive frailty is defined as a clinical condition characterized by both physical frailty and cognitive impairment, without reaching the criteria for dementia. The major goal of rehabilitation intervention is to assist patients in performing ordinary personal duties without the assistance of another person, or at the very least to remove the need for additional support, using adaptive approaches and facilities. In this regard, home-based rehabilitation allows patients to continue an intervention begun in a hospital setting while also ensuring support and assistance when access to healthcare systems is limited, such as during the present pandemic situation. We thus present Brain m-App, a tablet-based application designed for home-based cognitive rehabilitation of frail subjects, addressing spatial memory, attention, and executive functions. This app exploits the potential of 360° videos which are well-suited to home-based rehabilitation. The Brain m-app is made up of 10 days of activities that include a variety of exercises. The activities were chosen based on those patients used to do during their clinical practice in the hospital with the aim to improve their independence and autonomy in daily tasks. The preliminary usability test, which was conducted on five older people, revealed a sufficient level of usability, however, the sample size was modest. Results from the clinical study with 10 patients, revealed that Brain m-App improved especially executive functions and memory performances.

Active Videogaming Interventions in Adults with Neuromuscular Conditions: A Scoping Review

This review synthesized active videogaming (AVG) intervention literature over a 10-year period (2010-2020) for people with neuromuscular conditions (18-64 years of age), examining interventions that aimed to improve health and secondary conditions, physical activity, and outcomes quality of life (QOL). Systematic searches yielded 40 eligible studies. The major groups were multiple sclerosis (40%) and stroke (33%), and the study participants had mostly mild-to-moderate disability who were able to play games in a standing position. Research designs primarily involved randomized controlled trials (65%) and pre/post-trial design without a control group (28%). The majority of interventions used commercial off-the-shelf gaming systems, such as Nintendo Wii and Microsoft Kinect. Studies reported significant improvements in health outcomes, specifically in balance (n = 30/36), mobility (n = 24/27), and cardiorespiratory fitness (n = 6/8). Positive changes were also seen in secondary conditions (n = 8/12), physical activity (n = 3/4), and QOL outcomes (n = 8/16). AVG research for people with neuromuscular conditions has grown in both quantity and quality but several gaps remain. Study findings provide a roadmap for future AVG trials on understudied populations, and highlight technology and targeted outcomes as drivers of future intervention research.

Recent Considerations on Gaming Console Based Training for Multiple Sclerosis Rehabilitation

Multiple Sclerosis (MS) is a well-known, chronic demyelinating disease of the Central Nervous System (CNS) and one of the most common causes of disability in young adults. In this context, one of the major challenges in patients’ rehabilitation is to maintain the gained motor abilities in terms of functional independence. This could be partially obtained by applying new emerging and cutting-edge virtual/augmented reality and serious game technologies for a playful, noninvasive treatment that was demonstrated to be quite efficient and effective in enhancing the clinical status of patients and their (re)integration into society. Recently, Cloud computing and Internet of Things (IoT) emerged as technologies that can potentially revolutionize patients’ care. To achieve such a goal, a system that on one hand gathers patients’ clinical parameters through a network of medical IoT devices equipped with sensors and that, on the other hand, sends the collected data to a hospital Cloud for processing and analytics is required. In this paper, we assess the effectiveness of a Nintendo Wii Fit^® Plus Balance Board (WFBB) used as an IoT medical device adopted in a rehabilitation training program aimed at improving the physical abilities of MS patients (pwMS). In particular, the main scientific contribution of this paper is twofold: (i) to present a preliminary new pilot study investigating whether exercises based on the Nintendo Wii Fit^® balance board included in a rehabilitation training program could improve physical abilities and Quality of Life (QoL) of patients compared to that of a conventional four-week rehabilitation training program; (ii) to discuss how such a rehabilitation training program could be adopted in the perspective of near future networks of medical IoT-based rehabilitation devices, interconnected with a hospital Cloud system for big data processing to improve patients’ therapies and support the scientific research about motor rehabilitation. Results demonstrate the advantages of our approach from both health and technological points of view.

Application of Virtual Reality Rehabilitation System for the assessment of postural control while standing in typical children and peers with neurodevelopmental disorders

BACKGROUND

The assessment of postural control in children is crucial, due to its central role in their overall development. However, a tool that objectively quantifies the difference in postural control between typical and atypical developing children is lacking. In this study, we introduce a new technology (Virtual Reality Rehabilitation System, VRRS) for assessing children's postural control.

RESEARCH QUESTION

Is this new assessment tool capable to highlight the differences between typical development (TD) and atypical development, (children with Developmental Coordination Disorder (DCD) and Cerebral Palsy (CP))?

METHODS

30 TD children, 20 children with DCD and 27 with CP (mean ages: 6.29 ± 2.74; 9.11 ± 2.65; 10.07 ± 3.89 years) were tested with the VRRS Tablet with stabilometric balance platform. Postural parameters, related to the movements of the Centre of Pressure (COP) were collected. A multivariate analysis of variance (MANOVA) followed by a post-hoc analysis has been carried out. Moreover, the influence of age, sex, clinical scores and sub-diagnoses on parameters of interest has been explored.

RESULTS

COP distance and sway area in the three groups (TD: 7.35 ± 2.32 mm, 101.70 ± 64.16 mm²/s; DCD: 12.05 ± 8.19 mm, 188.46 ± 231.23 mm²/s; CP: 13.25 ± 8.09 mm, 239.13 ± 313.83 mm²/s, respectively) and all other VRRS parameters were significantly different among the three groups (p-values between 0.028 and <0.001). The TD group showed significantly different values than CP (p from < 0.03 to < 0.001) but not than DCD (p = n.s.). Clinical scores showed to correlate with the COP distances and Root Mean Square distances in all subgroups (p < 0.05). For age, only an influence was found within the TD group (p < 0.01); sex did not show to affect the outcomes (p = n.s.).

SIGNIFICANCE

An objective tool for quantitative measurement of postural control in childhood is needed. Our proposed VRRS tool could support the traditional assessment tests, highlighting differences between typical and atypical development.

Efficacy of Virtual Reality and Exergaming in Improving Balance in Patients With Multiple Sclerosis: A Systematic Review and Meta-Analysis

Multiple sclerosis (MS) is one of the most common causes of neurological progressive disease and can lead to loss of mobility, walk impairment, and balance disturbance. Among several rehabilitative approaches proposed, exergaming and virtual reality (VR) have been studied in the recent years. Active video game therapy could reduce the boredom of the rehabilitation process, increasing patient motivation, providing direct feedback, and enabling dual-task training. Aim of this systematic review was to assess the efficacy of exergaming and VR for balance recovery in patients with MS. PubMed, Scopus, and Web of Science were systematically searched from the inception until May 14, 2021 to identify randomized controlled trials (RCTs) presenting: patients with MS as participants, exergaming and VR as intervention, conventional rehabilitation as comparator, and balance assessment [Berg Balance Scale (BBS)] as outcome measure. We also performed a meta-analysis of the mean difference in the BBS via the random-effects method. Out of 93 records, this systematic review included and analyzed 7 RCTs, involving a total of 209 patients affected by MS, of which 97 patients performed exergaming or VR and 112 patients underwent conventional rehabilitation. The meta-analysis reported a significant overall ES of 4.25 (p < 0.0001), showing in the subgroup analysis a non-significant ES of 1.85 (p = 0.39) for the VR and a significant ES of 4.49 (p < 0.0001) for the exergames in terms of the BBS improvement. Taken together, these findings suggested that balance rehabilitation using exergames appears to be more effective than conventional rehabilitation in patients affected by MS.

Efficacy of Electrical Stimulation-Augmented Virtual Reality Training in Improving Balance in Individuals with Incomplete Spinal Cord Injury: Study Protocol of a Randomized Controlled Trial

STUDY DESIGN

This study is a single-blind, parallel, three-group, and randomized controlled trial.

PURPOSE

This study aimed to investigate the effectiveness of electrical stimulation-augmented virtual reality training in improving balance in individuals with incomplete spinal cord injury (iSCI).

OVERVIEW OF LITERATURE

Individuals with iSCI often face significant balance and mobility impairments affecting their quality of life. Scientific studies focusing on standing balance training in the iSCI population are limited. Virtual reality-based balance training has shown positive results in several neurological populations. Electrical stimulation has also proved to be effective in improving voluntary muscle strength in partially paralyzed muscles after iSCI as well as promoting neuroplasticity.

METHODS

Forty-eight iSCI participants will be recruited based on the inclusion criteria. The participants will be randomly assigned to any of the three groups: virtual reality-based balance training along with the electrical stimulation group, virtual reality-based balance training along with sham stimulation group, or virtual reality-based balance training group. The intervention will be delivered as 60-minute sessions, thrice a week for 4 weeks.

RESULTS

The performance of the participants will be assessed using the lower extremity motor score, static and dynamic balance assessment using TechnoBody ProKin tilting platform and Berg Balance Scale, Walking Index for Spinal Cord Injury, and World Health Organization Quality of Life-BREF at pre-intervention, after 4 weeks post-intervention, and at 1-month follow-up.

CONCLUSIONS

The trial will provide new knowledge about the effectiveness of electrical stimulation-augmented virtual reality training in improving balance in individuals with iSCI. The study results will contribute to the design of better rehabilitation programs for individuals with iSCI.

Feasibility and safety of an immersive virtual reality-based vestibular rehabilitation programme in people with multiple sclerosis experiencing vestibular impairment: a protocol for a pilot randomised controlled trial

INTRODUCTION

Vestibular system damage in patients with multiple sclerosis (MS) may have a central and/or peripheral origin. Subsequent vestibular impairments may contribute to dizziness, balance disorders and fatigue in this population. Vestibular rehabilitation targeting vestibular impairments may improve these symptoms. Furthermore, as a successful tool in neurological rehabilitation, immersive virtual reality (VRi) could also be implemented within a vestibular rehabilitation intervention.

METHODS AND ANALYSIS

This protocol describes a parallel-arm, pilot randomised controlled trial, with blinded assessments, in 30 patients with MS with vestibular impairment (Dizziness Handicap Inventory ≥16). The experimental group will receive a VRi vestibular rehabilitation intervention based on the conventional Cawthorne-Cooksey protocol; the control group will perform the conventional protocol. The duration of the intervention in both groups will be 7 weeks (20 sessions, 3 sessions/week). The primary outcomes are the feasibility and safety of the vestibular VRi intervention in patients with MS. Secondary outcome measures are dizziness symptoms, balance performance, fatigue and quality of life. Quantitative assessment will be carried out at baseline (T0), immediately after intervention (T1), and after a follow-up period of 3 and 6 months (T2 and T3). Additionally, in order to further examine the feasibility of the intervention, a qualitative assessment will be performed at T1.

ETHICS AND DISSEMINATION

The study was approved by the Andalusian Review Board and Ethics Committee, Virgen Macarena-Virgen del Rocio Hospitals (ID 2148-N-19, 25 March 2020). Informed consent will be collected from participants who wish to participate in the research. The results of this research will be disseminated by publication in peer-reviewed scientific journals.

Virtual Reality-Based Therapy Improves Fatigue, Impact, and Quality of Life in Patients with Multiple Sclerosis. A Systematic Review with a Meta-Analysis

Patients with multiple sclerosis (PwMS) have a high level of fatigue and a reduced quality of life (QoL) due to the impact of multiple sclerosis (MS). Virtual reality-based therapy (VRBT) is being used to reduce disability in PwMS. The aim of this study was to assess the effect of VRBT on fatigue, the impact of MS, and QoL in PwMS. Methods: A systematic review with meta-analysis was conducted through a bibliographic search on PubMed, Scopus, Web of Science, and PEDro up to April 2021. We included randomized controlled trials (RCTs) with PwMS that received VRBT in comparison to conventional therapy (CT) including physiotherapy, balance and strength exercises, and stretching or physical activity, among others; or in comparison to simple observation; in order to assess fatigue, MS-impact, and QoL. The effect size was calculated using Cohen’s standardized mean difference with a 95% confidence interval (95% CI). Results: Twelve RCTs that provided data from 606 PwMS (42.83 ± 6.86 years old and 70% women) were included. The methodological quality mean, according to the PEDro Scale, was 5.83 ± 0.83 points. Our global findings showed that VRBT is effective at reducing fatigue (SMD −0.33; 95% CI −0.61, −0.06), lowering the impact of MS (SMD −0.3; 95% CI −0.55, −0.04), and increasing overall QoL (0.5; 95% CI 0.23, 0.76). Subgroup analysis showed the following: (1) VRBT is better than CT at reducing fatigue (SMD −0.4; 95% CI −0.7, −0.11), as well as in improving the mental dimension of QoL (SMD 0.51; 95% CI 0.02, 1); (2) VRBT is better than simple observation at reducing the impact of MS (SMD −0.61; 95% CI −0.97, −0.23) and increasing overall QoL (SMD 0.79; 95% CI 0.3, 1.28); and (3) when combined with CT, VRBT is more effective than CT in improving the global (SMD 0.6, 95% CI 0.13, 1.07), physical (SMD 0.87; 95% CI 0.3, 1.43), and mental dimensions (SMD 0.6; 95% CI 0.08, 1.11) of QoL. Conclusion: VRBT is effective at reducing fatigue and MS impact and improving QoL in PwMS.

Outcome measures used in trials on gait rehabilitation in multiple sclerosis: A systematic literature review

Background

Multiple Sclerosis (MS) is associated with impaired gait and a growing number of clinical trials have investigated efficacy of various interventions. Choice of outcome measures is crucial in determining efficiency of interventions. However, it remains unclear whether there is consensus on which outcome measures to use in gait intervention studies in MS.

Objective

We aimed to identify the commonly selected outcome measures in randomized controlled trials (RCTs) on gait rehabilitation interventions in people with MS. Additional aims were to identify which of the domains of the International Classification of Functioning, Disability and Health (ICF) are the most studied and to characterize how outcome measures are combined and adapted to MS severity.

Methods

Pubmed, Cochrane Central, Embase and Scopus databases were searched for RCT studies on gait interventions in people living with MS according to PRISMA guidelines.

Results

In 46 RCTs, we identified 69 different outcome measures. The most used outcome measures were 6-minute walking test and the Timed Up and Go test, used in 37% of the analyzed studies. They were followed by gait spatiotemporal parameters (35%) most often used to inform on gait speed, cadence, and step length. Fatigue was measured in 39% of studies. Participation was assessed in 50% of studies, albeit with a wide variety of scales. Only 39% of studies included measures covering all ICF levels, and Participation measures were rarely combined with gait spatiotemporal parameters (only two studies).

Conclusions

Selection of outcome measures remains heterogenous in RCTs on gait rehabilitation interventions in MS. However, there is a growing consensus on the need for quantitative gait spatiotemporal parameter measures combined with clinical assessments of gait, balance, and mobility in RCTs on gait interventions in MS. Future RCTs should incorporate measures of fatigue and measures from Participation domain of ICF to provide comprehensive evaluation of trial efficacy across all levels of functioning.

Modern Technologies in the Rehabilitation of Patients with Multiple Sclerosis and Their Potential Application in Times of COVID-19

Background and Objectives: The COVID-19 pandemic required the adoption of new technologies to improve access to healthcare at an unprecedented speed, as social distancing became mandatory. The aim of this systematic review was to analyze the effectiveness of using new technologies in the rehabilitation of multiple sclerosis (MS) patients and discuss their potential role during the COVID-19 pandemic. Material and Methods: The studies were identified by searching two online databases-PUBMED and Web of Science. Combinations of the key words "Multiple sclerosis" and "e-health"; "Multiple sclerosis" and "virtual reality"; "Multiple sclerosis" and "telerehabilitation"; "Multiple sclerosis" and "new technologies"; "Multiple sclerosis" and "tele-exercise" were used to find suitable publications. Results: A total of 17 studies were included. Although the overall number of participants in all the studies was 904, two of the studies were conducted on the same group. Thus, a total of 854 participants were involved in the studies included. All participants were diagnosed with MS. In 10 studies, participants had to be diagnosed according to the McDonald criteria. Of the included studies: five involved intervention at participants' home, six were conducted using Xbox Kinect, and seven studies reported no adverse outcomes. Conclusion: The review proves telerehabilitation to be an effective motivational tool to restore and maintain both physical and cognitive function in patients with MS. Remote communication technologies seem to be measures of high effectiveness in rehabilitating and supporting MS patients especially during the COVID-19 pandemic, as the traditional rehabilitation option is less accessible or in some cases inaccessible for these patients.

Design and Evaluation of User-Centered Exergames for Patients With Multiple Sclerosis: Multilevel Usability and Feasibility Studies

BACKGROUND

Multiple sclerosis (MS) is a chronic inflammatory disease of the central nervous system. Patients with MS experience a wide range of physical and cognitive dysfunctions that affect their quality of life. A promising training approach that concurrently trains physical and cognitive functions is video game-based physical exercising (ie, exergaming). Previous studies have indicated that exergames have positive effects on balance and cognitive functions in patients with MS. However, there is still a need for specific, user-centered exergames that function as a motivating and effective therapy tool for patients with MS and studies investigating their usability and feasibility.

OBJECTIVE

The aim of this interdisciplinary research project is to develop usable and feasible user-centered exergames for the pressure-sensitive plate Dividat Senso by incorporating theoretical backgrounds from movement sciences, neuropsychology, and game research as well as participatory design processes.

METHODS

Focus groups (patients and therapists) were set up to define the user-centered design process. This was followed by the field testing of newly developed exergame concepts. Two sequential usability and feasibility studies were conducted on patients with MS. The first study included a single exergaming session followed by measurements. Between the first and second studies, prototypes were iterated based on the findings. The second study ran for 4 weeks (1-2 trainings per week), and measurements were taken before and after the intervention. For each study, participants answered the System Usability Scale (SUS; 10 items; 5-point Likert Scale; score range 0-100) and interview questions. In the second study, participants answered game experience-related questionnaires (Flow Short Scale [FSS]: 13 items; 7-point Likert Scale; score range 1-7; Game Flow questionnaire: 17 items; 6-point Likert Scale; score range 1-6). Mixed methods were used to analyze the quantitative and qualitative data.

RESULTS

In the first study (N=16), usability was acceptable, with a median SUS score of 71.3 (IQR 58.8-80.0). In the second study (N=25), the median SUS scores were 89.7 (IQR 78.8-95.0; before) and 82.5 (IQR 77.5-90.0; after), and thus, a significant decrease was observed after training (z=-2.077; P=.04; r=0.42). Moreover, high values were observed for the overall FSS (pre: median 5.9, IQR 4.6-6.4; post: median 5.8, IQR 5.4-6.2) and overall Game Flow Questionnaire (pre: median 5.0, IQR 4.7-5.3; post: median 5.1, IQR 4.9-5.3). A significant decrease was observed in the item perceived importance (FSS: z=-2.118; P=.03; r=0.42). Interviews revealed that user-centered exergames were usable, well accepted, and enjoyable. Points of reference were identified for future research and development.

CONCLUSIONS

The project revealed that the newly developed, user-centered exergames were usable and feasible for patients with MS. Furthermore, exergame elements should be considered in the development phase of user-centered exergames (for patients with MS). Future studies are needed to provide indications about the efficacy of user-centered exergames for patients with MS.

Getting into a "Flow" state: a systematic review of flow experience in neurological diseases

BACKGROUND

Flow is a subjective psychological state that people report when they are fully involved in an activity to the point of forgetting time and their surrounding except the activity itself. Being in flow during physical/cognitive rehabilitation may have a considerable impact on functional outcome, especially when patients with neurological diseases engage in exercises using robotics, virtual/augmented reality, or serious games on tablets/computer. When developing new therapy games, measuring flow experience can indicate whether the game motivates one to train. The purpose of this study was to identify and systematically review current literature on flow experience assessed in patients with stroke, traumatic brain injury, multiple sclerosis and Parkinson's disease. Additionally, we critically appraised, compared and summarized the measurement properties of self-reported flow questionnaires used in neurorehabilitation setting.

DESIGN

A systematic review using PRISMA and COSMIN guidelines.

METHODS

MEDLINE Ovid, EMBASE Ovid, CINAHL EBSCO, SCOPUS were searched. Inclusion criteria were (1) peer-reviewed studies that (2) focused on the investigation of flow experience in (3) patients with neurological diseases (i.e., stroke, traumatic brain injury, multiple sclerosis and/or Parkinson's disease). A qualitative data synthesis was performed to present the measurement properties of the used flow questionnaires.

RESULTS

Ten studies out of 911 records met the inclusion criteria. Seven studies measured flow in the context of serious games in patients with stroke, traumatic brain injury, multiple sclerosis and Parkinson's disease. Three studies assessed flow in other activities than gaming (song-writing intervention and activities of daily living). Six different flow questionnaires were used, all of which were originally validated in healthy people. None of the studies presented psychometric data in their respective research population.

CONCLUSION

The present review indicates that flow experience is increasingly measured in the physical/cognitive rehabilitation setting in patients with neurological diseases. However, psychometric properties of used flow questionnaires are lacking. For exergame developers working in the field of physical/cognitive rehabilitation in patients with neurological diseases, a valid flow questionnaire can help to further optimize the content of the games so that optimal engagement can occur during the gameplay. Whether flow experiences can ultimately have positive effects on physical/cognitive parameters needs further study.

Protocol for a controlled, randomized, blind, clinical trial to assess the effects of anodal transcranial direct current stimulation dorsolateral prefrontal cortex associated with balance training using games in the postural balance of older people

Aims: This study aims to evaluate the additional effect of anodal transcranial direct current stimulation (a-tDCS) applied on dorsolateral pré-frontal cortex on training postural balance with the use of video games in the aged.

Methods: This is a blinded, randomized, controlled clinical trial protocol, with older people of both genders. Participants will be randomized into three training groups: Group 1 (videogame balance training), group 2 (videogame balance training associated with anodal tDCS), group 3 (videogame balance training associated with sham tDCS). The training will be carried out twice a week for four weeks, totaling eight sessions, and will be performed with the Nintendo Wii videogame console, using games that stimulate the postural balance associated with tDCS, with anode applied over the left dorsolateral prefrontal cortex and cathode on the contralateral supraorbital region at 2 mA for 20 minutes. The postural balance will be assessed using the Mini Test of the Balance Assessment System and posturography. Evaluations will be carried out before and after eight training sessions and 30 days after the end of treatment.

Discussion: Some studies show favorable results from the use of video games in improving postural balance in older people; however, their effect does not remain long-term. TDCS associated with other therapies can potentiate and prolong the effects of these therapies owing to its ability to stimulate neurotrophins important for neurogenesis, facilitating tasks that require attention, and helping to consolidate learning and memory. The effect of the two associated techniques on balance has not yet been tested in this population.

The effects of exergaming on pain, postural control, technology acceptance and flow experience in older people with chronic musculoskeletal pain: a randomised controlled trial

BACKGROUND

Older people with chronic musculoskeletal pain are at risk of falls. This study aimed to investigate the effects of exergaming on pain and postural control in older people with chronic musculoskeletal pain. Secondary outcomes were technology acceptance, flow experience, perceived physical exertion, expended mental effort and heart rate.

METHODS

Fifty four older adults (age: 71 ± 5 years) with chronic musculoskeletal pain were randomised into 2 groups. Group 1 received exergaming training using the Interactive Rehabilitation and Exercise System (IREX®). Group 2 undertook traditional gym-based exercise (TGB). Both groups completed twice weekly 40-min exercise sessions for 6 weeks. Perceived pain was measured using a numeric pain rating scale and the Multidimensional Affect and Pain Survey questionnaire. Postural control was measured as sway using a Kistler™ force platform. Technology acceptance was measured with the Unified Theory of Acceptance and Use of Technology questionnaire and flow experience with the Flow State Scale. Physiological measures of perceived physical exertion, expended mental effort and heart rate were recorded during all sessions.

RESULTS

The exergaming group demonstrated significant reductions in pain intensity and thermal pain including a near significant approach in physical engagement in comparison to TGB group. Although no intervention effects on postural control were found, the exergaming group showed significant improvements in three sway measures (AP SD, ML SD and AP range) over time whereas significant improvements in ML range were found in the TGB group. Relating to technology acceptance, significant intervention effects on social influence and behavioural intention were found in the TGB group instead, although both groups demonstrated increases of acceptance over time. Regarding flow experience, concentration at task was significantly influenced in the TGB group and significant increases in flow variables over time were observed in both groups. Significant increases over time in perceived physical exertion and expended mental effort were found in both groups.

CONCLUSION

Our findings support the potential of exergaming to alleviate pain and improve balance in older people with chronic musculoskeletal pain. Both forms of exercise are acceptable, intrinsically motivating and show evidence of benefit to older people with chronic musculoskeletal pain.

Effectiveness of Exergaming in Improving Cognitive and Physical Function in People With Mild Cognitive Impairment or Dementia: Systematic Review

BACKGROUND

Individuals with mild cognitive impairment and dementia have impaired physical and cognitive functions, leading to a reduced quality of life compared with those without such impairment. Exergaming, which is defined as a combination of exercise and gaming, is an innovative, fun, and relatively safe way to exercise in a virtual reality or gaming environment. Therefore, exergaming may help people living with mild cognitive impairment or dementia to overcome obstacles that they may experience regarding regular exercise and activities.

OBJECTIVE

The aim of this systematic review was to review studies on exergaming interventions administered to elderly individuals with mild cognitive impairment and dementia, and to summarize the results related to physical and cognitive functions such as balance, gait, executive function, and episodic memory.

METHODS

We searched Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, PsycINFO, Amed, and Nursing Database for articles published from the inception of the respective databases to January 2019. We included all clinical trials of exergaming interventions in individuals with mild cognitive impairment and dementia for review. The risk of bias was independently evaluated by two reviewers using the Cochrane Collaboration and Risk of Bias in Non-randomized Studies of Interventions tools.

RESULTS

Ten studies involving 702 participants were included for review. There was consistent evidence from 7 studies with a low risk of bias showing statistically significant effects of exergaming on cognitive functioning in people with mild cognitive impairment and dementia. With respect to physical function, 3 of 5 full-scale studies found positive results, and the intensity of most games was classified as moderate.

CONCLUSIONS

Overall, exergaming is an innovative tool for improving physical and cognitive function in people with mild cognitive impairment or dementia, although there is high heterogeneity among studies in terms of the duration, frequency, and gaming platform used. The quality of the included articles was moderate to high. More high-quality studies with more accurate outcome indicators are needed for further exploration and validation of the benefits of exergaming for this population.

Effect of video-based exergaming on arm and cognitive function in persons with multiple sclerosis: A randomized controlled trial

BACKGROUND

Developments in rehabilitation technology such as video-based exergaming contributes to the treatment process as well as to increase the active participation of persons with multiple sclerosis (pwMS). The aim was to investigate the effect of video-based exergaming training on upper extremity and cognitive function as well as core stability, walking, depression, fatigue, and quality of life in pwMS.

METHODS

This randomized controlled trial included 60 pwMS who were randomly divided into three groups; video-based exergaming (n = 21), conventional rehabilitation (n = 19), and control groups (n = 20). The experimental groups received therapy sessions once a week for 8 weeks. All the participants were assessed at baseline and after 8 weeks. The outcome measures included upper extremity and cognitive functions as well as core stability, walking, depression, fatigue, and quality of life measures.

RESULTS

Significant improvements were observed in the primary outcome, measured by Nine-Hole Peg Test in the video-based exergaming [before= 25.8 (11.1) s; after= 22.3 (11.0) s] and conventional rehabilitation [before= 23.3 (8.1) s; after= 19.9 (3.8) s] groups (p < 0.05). Cognitive functions (with the exception of processing speed in the conventional rehabilitation group), most of the lower extremity functions, balance-related measures, fatigue and quality of life levels were significantly improved in the video-based exergaming and conventional rehabilitation groups, however, only the depression level was significantly decreased in the video-based exergaming (p < 0.05). Several significant differences were observed in the changes of the control group compared to the video-based exergaming and conventional rehabilitation groups (p < 0.05).

CONCLUSION

This study suggests that video-based exergaming is almost as effective as conventional rehabilitation regarding improving walking, upper and lower extremity functions, cognitive functions, fatigue, depression, and health-related quality of life in pwMS.

Biofeedback Based Home Balance Training can Improve Balance but Not Gait in People with Multiple Sclerosis

Background

Impaired balance is common in people with multiple sclerosis (MS) and can be present even in those with a mild disability level. With increasing disability, gait, and balance impairment progress, and lead to increased risk of falls. In some recent studies, interactive commercial video games were used for improving balance, but their limitation is their lack of individual training parameter settings needed for rehabilitation purposes. The aim of this study was to evaluate the feasibility and effect of balance exercise in the home setting using the rehabilitation Homebalance® system.

Methods

A single-centre, controlled, single blind study with allocation to intervention group or to control group was utilised. Participants were assessed at baseline, after four weeks of home-based balance training, and follow-up after four weeks. The primary outcomes were the Berg Balance Test (BBT). The secondary outcome measures included the Mini-BESTest, Timed Up, and Go Test (part of Mini-BESTest), and spatio-temporal gait parameter evaluation using the GAITRite instrument. The patient reported outcomes (PRO) included the 12-Item MS Walking Scale, Activities-specific Balance Confidence Scale, and the Falls Efficacy Scale.

Results

A total of 39 people with Multiple Sclerosis (10 men) were enrolled into the study. The mean age of participants was 40.69 ± 10.2 years, with a mean disease duration 14.76 ± 9.1 years and mean disability level 3.8 ± 1.9 EDSS (EDSS range 1.5–7). Statistically significant improvements within the home exercise group were present for the BBT and the Mini-BESTest. This improvement was more significant in the subgroup with moderate and higher disability (EDSS 4.5–7). All other gait parameters and PRO did not show any improvement. Follow-up assessment after four weeks showed that the reached improvement persisted for a short time period after finishing the regular training regimen.

Conclusion

In comparison with no intervention, a short-term programme of home-based balance training using Homebalance® improved balance but not gait performance in a group of people with MS. It seems that home-based balance training tailored according to individual needs by a physiotherapist may be a future approach to consider for telerehabilitation of people with MS.

Comparison of the effects of two different exergaming systems on balance, functionality, fatigue, and quality of life in people with multiple sclerosis: A randomized controlled trial

BACKGROUND

Balance disorders, fatigue, and walking impairments are the most common symptoms of multiple sclerosis (MS), which lead to a decrease in quality of life. To cope with these disability-increasing symptoms, it is important to select and regularly apply appropriate rehabilitation approaches. In recent years, virtual reality approaches have been suggested as a potentially useful tool in rehabilitation. Exergaming systems are used in the treatment of symptoms associated with MS, but there are few randomized controlled studies investigating the efficacy of these systems.

OBJECTIVE

To investigate and compare the effects of exercise training with two different exergaming systems on balance, functionality, fatigue, and quality of life in people with multiple sclerosis (PwMS).

METHODS

Forty-seven volunteer PwMS were included in the study and randomized to the group I (Nintendo Wii Fit), group II (Balance Trainer), and group III (control group). The participants in the study groups underwent an exercise program under the supervision of a physiotherapist on 2 days a week for 8 weeks. Outcome measures were the Berg Balance Scale (BBS), Timed Up and Go test (TUG), Six-Minute Walk Test (6MWT), Fatigue Severity Scale (FSS), and Multiple Sclerosis International Quality of Life Questionnaire (MusiQol), which were performed before and after the treatment.

RESULTS

Forty-two participants completed the study protocol. All parameters evaluated in group I and II showed statistically significant improvement after treatment. Changes in all outcome measures were found to be superior in group I compared with group III. Similarly, all measures except the 6MWT were found to be superior in group II compared with group III. Changes in BBS and MusiQol were found to be superior in group I compared with group II.

CONCLUSION

In comparison with no intervention, exergaming with Nintendo Wii Fit and Balance Trainer improves balance, increases functionality, reduces fatigue severity, and increases quality of life in PwMS.

An Immersive Motor Protocol for Frailty Rehabilitation

Frailty is a pre-clinical condition that worsens physical health and quality of life. One of the most frequent symptoms of frailty is an increased risk of falling. In order to reduce this risk, we propose an innovative virtual reality motor rehabilitation program based on an immersive tool. All exercises will take place in the CAVE, a four-screen room with a stationary bike. The protocol will include two types of exercises for the improvement of balance: "Positive Bike" and "Avoid the Rocks." We will choose evaluation scales related to the functional aspects and subjective perception of balance. Our aim is to prove that our innovative motor rehabilitation protocol is as effective as or more effective than classical rehabilitation.

Virtual reality in multiple sclerosis rehabilitation: A review on cognitive and motor outcomes

Multiple sclerosis (MS) is a demyelinating neurodegenerative disease with lesions involving the central nervous system. Clinical symptoms consist of disturbances in motor activity (e.g., weakness, spasticity, and tremor), sensory functioning (e.g., pain), visual functions (e.g., diplopia and optic neuritis), besides different cognitive (attention deficit and executive dysfunction) and behavioral abnormalities. This review aims to evaluate the role of VR tools in cognitive and motor rehabilitation of MS patients. Studies performed between 2010 and 2017 and fulfilling the selected criteria were searched on PubMed, Scopus, Cochrane and Web of Sciences databases, by combining the terms "VR rehabilitation" and "MS". Our findings showed that, following the use of VR training, MS patients presented a significant improvement in motor (especially gait and balance) and cognitive function (with regard to executive and visual-spatial abilities, attention and memory skills). This review supports the idea that rehabilitation through new VR tools could positively affect MS patients' outcomes, by boosting motivation and participation with a better response to treatment.

Acceptance of Mobile Health Apps for Disease Management Among People With Multiple Sclerosis: Web-Based Survey Study

Background

Mobile health (mHealth) apps might have the potential to promote self-management of people with multiple sclerosis (MS) in everyday life. However, the uptake of MS apps remains poor, and little is known about the facilitators and barriers for their efficient utilization, such as technology acceptance.

Objective

The aim of this study was to examine the acceptance of mHealth apps for disease management in the sense of behavioral intentions to use and explore determinants of utilization among people with MS based on the Unified Theory of Acceptance and Use of Technology (UTAUT).

Methods

Participants for this Web-based cross-sectional study were recruited throughout Germany with the support of regional MS associations and self-help groups. To identify determinants of intention to use MS apps, a measure based on the UTAUT was adapted with 4 key determinants (performance expectancy, effort expectancy, social influence, and facilitating conditions) and extended by Intolerance of Uncertainty (IU) and electronic health literacy. Potential influencing effects of both MS and computer self-efficacy (C-SE) as mediators and fatigue as a moderator were analyzed using Hayes’s PROCESS macro (SPSS version 3.0) for IBM SPSS version 24.0.

Results

A total of 98 participants (mean age 47.03 years, SD 10.17; 66/98, 67% female) with moderate fatigue levels completed the survey. Although most participants (91/98, 92%) were daily smartphone users, almost two-thirds (62/98, 63%) reported no experience with MS apps. Overall, the acceptance was moderate on average (mean 3.11, SD 1.31, minimum=1 and maximum=5), with lower scores among persons with no experience (P=.04) and higher scores among current users (P<.001). In multiple regression analysis (R²=63% variance explained), performance expectancy (beta=.41) and social influence (beta=.33) were identified as significant predictors of acceptance (all P<.001). C-SE was confirmed as a partial mediator in the relationship between IU and acceptance (indirect effect: B=−.095, 95% CI −0.227 to −0.01). Furthermore, a moderated mediation by C-SE was shown in the relationship between IU and behavioral intentions to use MS apps for low (95% CI −0.42 to −0.01) and moderate levels (95% CI −0.27 to −0.01) of fatigue.

Conclusions

Overall, this exploratory pilot study indicates for the first time that positive expectations about the helpfulness for self-management purposes and social support might be important factors to be considered for improving the acceptance of MS apps among smartphone users with MS. However, given some inconsistent findings, especially regarding the role of effort expectancy and IU and self-efficacy, the conceptual model needs replication with a larger sample of people with MS, varying more in fatigue levels, and a longitudinal assessment of the actual usage of MS apps predicted by acceptance in the sense of behavioral intentions to use.

The feasibility, acceptability and outcomes of exergaming among individuals with cancer: a systematic review

Background

Individuals with cancer have reduced quality of life, functionality, range of motion, strength, and an increase in pain and fatigue. Exergaming appears to be an effective rehabilitation tool for Parkinson’s disease, multiple sclerosis and post-stroke patients to improve functionality, balance and quality of life; however, the usefulness of exergaming in individuals with cancer is unknown. The aim of this systematic review is to describe exergaming interventions delivered to adults with a current or previous cancer diagnosis and to report the feasibility, acceptability and outcomes of such interventions.

Methods

Studies reporting on exergaming interventions delivered to individuals with a current or previous cancer diagnosis were included. 12 electronic databases were searched. Eight articles (seven interventions) were identified. Data were extracted and assessed for quality by two reviewers.

Results

Three interventions were delivered at hospital, two at home, one at a clinical laboratory, and one did not report. Two interventions were delivered by a physiotherapist, two by an occupational therapist, and one by a nurse, research staff and an exercise physiologist. The Nintendo Wii was used in four of seven studies, whilst the remaining three used the IREX system, BrightArm Duo Rehabilitation System or a custom made exergame. Studies showed that most participants enjoyed the exergaming intervention, and would recommend their use, with some preferring exergaming over standard care interventions. Adherence rates and enjoyment appear greater during exergaming than standard care. Exergaming interventions appear to support improvements balance, function, physical activity levels, strength, fatigue, emotions, cognition and pain.

Conclusion

Exergaming interventions delivered to individuals with cancer show great heterogeneity; differing in duration, frequency and gaming platform. The disease stage and severity of those included, and the outcome measures assessed also vary widely making it difficult to conclude its effectiveness at this time. However, adherence rates and enjoyment appear greater during exergaming compared to standard care, supporting the feasibility and acceptability of this type of intervention delivery for adults with cancer.

The acceptance of the clinical photographic posture assessment tool (CPPAT)

BACKGROUND

There is a lack of evidence-based quantitative clinical methods to adequately assess posture. Our team developed a clinical photographic posture assessment tool (CPPAT) and implemented this tool in clinical practice to standardize posture assessment. The objectives were to determine the level of acceptance of the CPPAT and to document predictors as well as facilitators of and barriers to the acceptance of this tool by clinicians doing posture re-education.

METHODS

This is a prospective study focussing on technology acceptance. Thirty-two clinician participants (physical therapists and sport therapists) received a 3-5 h training workshop explaining how to use the CPPAT. Over a three-month trial, they recorded time-on-task for a complete posture evaluation (photo - and photo-processing). Subsequently, participants rated their acceptance of the tool and commented on facilitators and barriers of the clinical method.

RESULTS

Twenty-three clinician participants completed the trial. They took 22 (mean) ± 10 min (SD) for photo acquisition and 36 min ± 19 min for photo-processing. Acceptance of the CPPAT was high. Perceived ease of use was an indirect predictor of intention to use, mediated by perceived usefulness. Analysis time was an indirect predictor, mediated by perceived usefulness, and a marginally significant direct predictor. Principal facilitators were objective measurements, visualization, utility, and ease of use. Barriers were time to do a complete analysis of posture, quality of human-computer interaction, non-automation of posture index calculation and photo transfer, and lack of versatility.

CONCLUSION

The CPPAT is perceived as useful and easy to use by clinicians and may facilitate the quantitative analysis of posture. Adapting the user-interface and functionality to quantify posture may facilitate a wider adoption of the tool.

e-Health and multiple sclerosis: An update

e-Health (or digital healthcare) is becoming increasingly relevant in multiple sclerosis (MS) clinical management. We aim to review and discuss current status and future perspective of e-health in people with multiple sclerosis (pwMS). The first part of this review describes how information on MS can be conveyed through the Web and digital media. The second part illustrates recent advances in digital technology that can improve clinical management and in motor and cognitive rehabilitation of pwMS. Finally, this review advocates future development of the "digital case manager" as a new figure to coordinate clinical management and care of pwMS. The digital revolution is changing the medical approach to MS in terms of information conveying and sharing, rehabilitation, and healthcare management.

Characteristics, Usability, and Users Experience of a System Combining Cognitive and Physical Therapy in a Virtual Environment: Positive Bike

We present the architecture and usability evaluation of virtual reality system-"Positive Bike"-designed for improving cognitive and motor conditions in frail elderly patients. The system consists of a cycle-ergometer integrated in an immersive virtual reality system (CAVE) which allows combining motor and cognitive exercises according to a "dual-task" paradigm. We tested the usability and user's experience of the prototype in a pilot evaluation study that involved five elderly patients. The prototype was tested in one-session training to understand the limitations and areas for improvement of our system. The evaluation consisted in (i) usability assessment using the system usability scale; (ii) evaluation of user's engagement using the flow state scale; and (iii) expert evaluation involving interviews with domain experts. Results showed a good usability, both for system usability scale and the semi-structured interview. The level of flow (i.e., enjoyment with the task at hand) measured using the short flow state scale, was also high. Analysis of semi-structured interview carried out with domain experts provided further indications to improve the system. Overall, these findings show that, despite some limitations, the system is usable and provides an enjoyable user's experience.

Effects of a Home-Based Resistance Exercise in Chinese Individuals Living With Physical Disability: Resistance Exercise on PWPD

PURPOSE

The purpose of this study was to explore the effect of a home-based resistance exercise program for people living with physical disability.

DESIGN

A quasiexperimental study.

METHOD

Forty participants enrolled, and 24 completed the 12-week study with 13 in the intervention group and 11 in the control group. Outcomes were measured by pretests and posttests, including Six-Minute Walk Test, Five Times Sit-to-Stand Test, 10-Meter Walk Test, Timed Up and Go, One Repetition Maximum, World Health Organization Disability Assessment Schedule 2.0, and Self-administered Short Form Health Survey.

FINDINGS

Outcomes of participants within intervention group improved significantly after the training.

CONCLUSIONS

This home-based resistance exercise demonstrated impact on improving the functioning of the participants.

CLINICAL RELEVANCE

A well-developed home-based resistance exercise for people with disability will improve their physical functioning. The trainers for the home-based program should have frequent interaction with the group to determine how to improve the outcome of physical abilities. Community health nurses could be taught how to conduct resistance exercise so that it will become routine care in the community health centers for people with disability.
