Current Trends in Exercise Intervention Research, Technology, and Behavioral Change Strategies for People With Disabilities: A Scoping Review

Effects of technology-supported exercise programs on the knee pain, physical function, and quality of life of individuals with knee osteoarthritis and/or chronic knee pain: A systematic review and meta-analysis of randomized controlled trials

OBJECTIVE

The study sought to examine the effects of technology-supported exercise programs on the knee pain, physical function, and quality of life of individuals with knee osteoarthritis and/or chronic knee pain by a systematic review and meta-analysis of randomized controlled trials.

MATERIALS AND METHODS

We searched MEDLINE, EMBASE, CINAHL Plus, and the Cochrane Library from database inception to August 2020. A meta-analysis and subgroup analyses, stratified by technology type and program feature, were conducted.

RESULTS

Twelve randomized controlled trials were reviewed, all of which implemented the programs for 4 weeks to 6 months. Telephone, Web, mobile app, computer, and virtual reality were used to deliver the programs. The meta-analysis showed that these programs were associated with significant improvements in knee pain (standardized mean difference [SMD] = -0.29; 95% confidence interval [CI], -0.48 to -0.10; P = .003) and quality of life (SMD = 0.25; 95% CI, 0.04 to 0.46; P = .02) but not with significant improvement in physical function (SMD = 0.22; 95% CI, 0 to 0.43; P = .053). Subgroup analyses showed that some technology types and program features were suggestive of potential benefits.

CONCLUSIONS

Using technology to deliver the exercise programs appears to offer benefits. The technology types and program features that were associated with health values have been identified, based on which suggestions are discussed for the further research and development of such programs.

Leisure-time physical activity interventions for children and adults with cerebral palsy: a scoping review

AIM

To summarize current evidence on the effects and reach of leisure-time physical activity (LTPA) interventions among children and adults with cerebral palsy (CP).

METHOD

Systematic searches were conducted in PubMed, CINAHL, and Google Scholar to identify randomized controlled trials (RCTs) of LTPA interventions in CP. Data from eligible studies were extracted for qualitative synthesis.

RESULTS

Forty-nine studies enrolled a total of 1513 participants (mean [SD] age 13y [7y], range 5-43y; 818 males, 655 females, 40 not reported) and primarily included ambulatory children. RCTs underrepresented adults and people in Gross Motor Function Classification System (GMFCS) levels IV and V. Forty-one studies reported at least one favorable benefit from LTPA. Benefits included improvements to musculoskeletal strength, cardiorespiratory fitness, quality of life, spasticity, participation, and core aspects of physical function. Regarding reach, only 34% of people that were contacted to participate enrolled within a study. A smaller percentage of participants dropped out from intervention (8%) and follow-up periods (3%).

INTERPRETATION

Study findings highlight effective interventions to improve health, fitness, and function. To enhance the reach and generalizability of LTPA trials for CP, future studies should examine how to increase study sample sizes and aim to include a better representation of adults and people in GMFCS levels IV and V.

WHAT THIS PAPER ADDS

People with cerebral palsy (CP) may experience improvements in health, fitness, and physical function from leisure-time physical activity (LTPA) interventions. Effective interventions include exercise training, active video games, recreation activities, behavioral coaching, and motor skills training. Interventions that incorporate telehealth technology, behavioral coaching, and community resources may enhance LTPA. Interventions primarily include children in Gross Motor Functional Classification System (GMFCS) levels I to III. Adults, wheelchair users, and those in GMFCS levels IV and V are underrepresented.

Individualized Aerobic Exercise in Neuromuscular Diseases: A Pilot Study on the Feasibility and Preliminary Effectiveness to Improve Physical Fitness

OBJECTIVE

Clear guidelines to prescribe aerobic exercise in neuromuscular diseases (NMD) are lacking, which hampers effective application in neuromuscular rehabilitation. This pilot study evaluated the feasibility and preliminary effectiveness of an individualized aerobic exercise program according to a recently developed training guide (B-FIT) to improve physical fitness in individuals with NMD.

METHODS

Thirty-one individuals who were ambulatory and had 15 different slowly progressive NMD participated in a 4-month, polarized, home-based, aerobic exercise program. The program included 2 low-intensity sessions and 1 high-intensity session per week. Feasibility outcomes were the following: completion rate, proportion of followed sessions, adverse events, and participant and therapist satisfaction based on a self-designed questionnaire. Submaximal incremental exercise tests were used to assess the effects on physical fitness.

RESULTS

Twenty-six participants (84%) completed the B-FIT program, and the proportion of followed sessions was >75%. Three adverse events were reported and resolved. Regarding satisfaction, participants (based on n = 9) reported feeling fitter, but training was considered insufficiently challenging. Physical therapists (n = 5) reported that B-FIT provides a clear, well-grounded guidance. They perceived the time investment for initiating the program and the carry-over to primary care as the main barriers. The mean (SD) submaximal heart rate (based on n = 20) reduced significantly by -6.5 beats per minute (95% CI = -11.8 to -1.2), from 121.7 (16.5) at baseline to 115.2 (14.3) after intervention. Submaximal ratings of perceived exertion, anaerobic threshold, and peak workload also improved significantly (P < .05).

CONCLUSION

The outcomes of this pilot study suggest that individualized aerobic exercise according to B-FIT is feasible and has potential to improve physical fitness in a wide variety of slowly progressive NMD. However, some barriers must be addressed before investigating the efficacy in a randomized controlled trial.

IMPACT

The outcomes of this study demonstrate the feasibility of individualized aerobic exercise according to the B-FIT training guide and the potential to improve physical fitness in NMD. Physical therapists indicated that the use of B-FIT provides a clear, well-grounded guidance. The training guide can support health care professionals in the application of aerobic exercise in adult neuromuscular rehabilitation.

LAY SUMMARY

Individualized exercise according to the B-FIT training guide is feasible in a wide variety of slowly progressive NMD and might help improve physical fitness.

Association of changes in cardiorespiratory fitness with health-related quality of life in young adults with mobility disability: secondary analysis of a randomized controlled trial of mobile app versus supervised training

Background

Young adults with mobility disability report lower health-related quality of life (HRQoL) than their able-bodied peers. This study aims to examine potential differences between the effects of mobile app versus supervised training and the association of cardiorespiratory fitness change with HRQoL in young adults with mobility disability.

Methods

This is a secondary analysis of a parallel randomized controlled trial of a mobile app (n = 55) and a supervised health program (n = 55) that was provided for 12 weeks to 110 adults (18–45 years) with self-perceived mobility disability. Recruitment took place at rehabilitation centers in Stockholm, Sweden. Cardiorespiratory fitness was estimated from the results of a submaximal cycle ergometer test and HRQoL was assessed with the SF-36 questionnaire. Follow up was at 6 weeks, 12 weeks, and 1-year and all examinations were performed by blinded investigators. Between group differences of changes in HRQoL at follow up were estimated in intention-to-treat analysis using linear regression models. Crude and adjusted mixed-effects models estimated the associations between cardiorespiratory fitness change and HRQoL. Stratified analysis by intervention group was also performed.

Results

In total, 40/55 from the mobile app group and 49/55 from the supervised training group were included in the intention to treat analysis. No significant differences were observed between the effects of the two interventions on HRQoL. In both crude and adjusted models, cardiorespiratory fitness change was associated with the general health (adjusted β = 1.30, 95% CI: 0.48, 2.13) and emotional role functioning (adjusted β = 1.18, 95% CI: 0.11, 2.25) domains of SF-36. After stratification, the associations with general health (adjusted β = 1.88, 95% CI: 0.87, 2.90) and emotional role functioning (adjusted β = 1.37, 95% CI: 0.18, 2.57) were present only in the supervised group.

Conclusion

This study found positive associations between cardiorespiratory fitness change and HRQoL in young adults with mobility disability who received supervised training. The effects of mobile app versus supervised training on HRQoL remain unclear.

Clinicians' perspectives on inertial measurement units in clinical practice

Inertial measurement units (IMUs) have been increasingly popular in rehabilitation research. However, despite their accessibility and potential advantages, their uptake and acceptance by health professionals remain a big challenge. The development of an IMU-based clinical tool must bring together engineers, researchers and clinicians. This study is part of a developmental process with the investigation of clinicians’ perspectives about IMUs. Clinicians from four rehabilitation centers were invited to a 30-minute presentation on IMUs. Then, two one-hour focus groups were conducted with volunteer clinicians in each rehabilitation center on: 1) IMUs and their clinical usefulness, and 2) IMUs data analysis and visualization interface. Fifteen clinicians took part in the first focus groups. They expressed their thoughts on: 1) categories of variables that would be useful to measure with IMUs in clinical practice, and 2) desired characteristics of the IMUs. Twenty-three clinicians participated to the second focus groups, discussing: 1) functionalities, 2) display options, 3) clinical data reported and associated information, and 4) data collection duration. Potential influence of IMUs on clinical practice and added value were discussed in both focus groups. Clinicians expressed positive opinions about the use of IMUs, but their expectations were high before considering using IMUs in their practice.

[Robotic mechanotherapy in patients with multiple sclerosis with impaired walking function]

OBJECTIVE

To study an effect of robotic mechanotherapy on the functional condition of patients with multiple sclerosis (MS) with impaired walking function using the ExoAtlet exoskeleton.

MATERIALS AND METHODS

A prospective open-source, uncontrolled, single-center study included 44 patients (main group, MG) with remitting course in remission (RRS) and secondary-progressive course (VPRS) of MS with 3 to 8 points on the Extended Disability Status Scale (EDSS). Eighteen people (subgroup 1) of this group were re-examined after 3 months and 8 people completed the second rehabilitation course (subgroup 2). Neurological deficits and functional condition of patients were assessed using the EDSS, the Multiple sclerosis functional composite (MSFC) test, which includes the assessment of walking - Timed 25- Footwalk, the assessment of upper limb functions - 9-HolePegTest (9-HPT), the assessment of mental abilities - Symbol Digit Modalities Test (SDMT). Additionally, cognitive functions were assessed by the Montreal Cognitive Assessment Scale (MoCA).

RESULTS

The improvement in the EDSS score was 0.23 points (5%, p<0.001) after the first course and 0.64 points (12%, p<0.02) after 3 months. The study of the pyramid system showed an improvement of this indicator by 0.29 points (10.2%, p<0.02) in patients of MG and by 1 point (32.3%, p<0.05) in subgroup 2. The SDMT subtest showed the improvement by 2.3 points (4.5%, p<0.02) in MG. In subgroup 2, the improvement by 17.1 points (38.9%), p<0.05) before the start of the 2nd course and by 22.9 points (52%, p<0.02) at the end of the 2nd course of rehabilitation was observed. The improvement of the Timed 25-Foot walk test in MG patients was 3.1 seconds (19.6%, p<0.001), the 9-Hole Peg Test on the dominant hand was 1.56 seconds (5.1%, p<0.02), and on the non - dominant hand 2.28 seconds (6.2%, p<0.02). After rehabilitation, the MoCA test showed the significant (p<0.001) improvement in cognitive functions by 1.6 points (6.1%) in MG and by 1.9 points (7.5%, p<0.05) in subgroup 2.

CONCLUSION

The results have shown the effectiveness regarding the problems in MS patients and the prospects for further study of the possibilities of robotic assistance to walking and support a vertical posture using the ExoAtlet exoskeleton in order to restore walking function in MS patients with motor deficits.

Critical factors influencing the decision to enroll in a physical activity intervention among a predominant group of adults with spinal cord injury: a grounded theory study

Study design

Grounded theory qualitative approach.

Objectives

To examine critical factors associated with interest in enrolling in a physical activity (PA) research intervention among a predominant group of adults with spinal cord injury (SCI) and develop a theory that can enhance future recruitment success.

Setting

Participants were recruited through the network of a community exercise facility for people with physical disabilities.

Methods

Interviews were conducted with 22 wheelchair users (mean age 46 ± 13 years; SCI [n = 19], cerebral palsy [n = 1]; multiple sclerosis [n = 1]; and bilateral limb loss [n = 1]) in either a one-on-one format or focus group. Interview data were coded, and these codes were organized into conceptual categories using a constructivist grounded theory framework.

Results

Adults with SCI conceive three core concerns with enrolling into a PA trial: (1) capability to participate in the program due to scheduling, transportation, and secondary health conditions; (2) mental balancing of anticipated benefits versus the difficulty of starting the program; and (3) desirability of the program characteristics based on their preferences and needs. Concerns were organized into a theory that may enhance future recruitment success.

Conclusions

Recruitment is often overlooked in PA research for people with SCI despite it being a primary rate-limiting factor that severely limits the external validity of published studies. Study findings identified core recruitment concerns that are likely similar with general barriers to PA participation. This paper proposed a 3-step decision-making process that can serve as a starting point for overcoming recruitment issues in PA research with people with SCI.

Research Trends and Recommendations for Physical Activity Interventions Among Children and Youth With Disabilities: A Review of Reviews

This scoping review synthesized reviews of physical activity (PA) interventions for children and youth with disabilities to highlight promising elements of effective interventions, research methodological limitations, and research priorities. Twenty studies were eligible and underwent three rounds of review by an expert panel. Rich and diverse PA programs derived potential short-term benefits toward health, function, and PA. Strategies to increase sample sizes included embedding programs in the community and using information communication technology to deliver exercise programs. Methodological limitations of interventions included a lack of generalizability, transferability, and scientific rigor. Three research priorities were identified: develop and report precision-based intervention strategies, identify strategies that promote both long-term and sustainable PA participation and outcomes, and develop scalable interventions and recruitment strategies. If addressed, these areas could enhance the impact of PA interventions for children and youth with disabilities.

Robotic mechanotherapy: the possibility to use an exoskeleton for lower limb rehabilitation in patients with multiple sclerosis and impaired walking function

Background: Robotic mechanotherapy is considered as a promising area of physical rehabilitation of multiple sclerosis patients, while it ensures high training efficacy. Aim: To study the effect of physical training using with the ExoAtlet exoskeleton for lower extremities the functioning of patients with multiple sclerosis. Materials and methods: This was a prospective, open, uncontrolled, single center study. The rehabilitation course with the ExoAtlet exoskeleton included 43 patients (14 male and 29 female, aged from 28 to 59 years, mean age 43,5 ± 9,12 years) with remitting multiple sclerosis in remission (RMS-R) (n = 20) and secondary progressive course (VPRS) (n = 23), with the EDSS scores from 3 to 8. One of the inclusion criteria was the presence of motor paresis of the lower extremities. Training with the ExoAtlet exoskeleton was performed 5 days a week for two weeks. The neurological deficits and functioning were assessed with the Kurtzke expanded disability status scale (EDSS), the multiple sclerosis functional composite (MSFC) test, including the assessment of walking (Timed 25 Footwalk), of upper limb functions (9-Hole PegTest, 9-HPT), and of mental functioning (Symbol Digit Modalities Test, SDMT) before and after the rehabilitation course. Cognitive functions were assessed by the Montreal Cognitive Assessment (MoCA) scale. Results: The rehabilitation course resulted in a significant decrease of neurological deficiency by EDSS (by 0.26 score, 5%, p < 0.001). The MSFC test showed an improvement in all subtests: SDMT by 2 points, or 4.9% (p = 0.018), Timed 25-Footwalk by 3.2 seconds, or 19.6% (p < 0.001), 9-HPT for the dominant hand by 1.6 seconds, or 5% (p = 0.004), and for the non-dominant hand by 2.1 seconds, or 6.2% (p = 0.006). The improvement in the MoCA test after the rehabilitation course was 1.6 points, or 6% (p < 0.001). Conclusion: The study confirmed the positive effect of the exoskeleton in the lower extremities, such as restoration of the walking function in multiple sclerosis patients. There was a positive trend towards restoring of hand motor skills and cognitive functions.

Italian validation of the caregiving tasks in multiple sclerosis scale (CTiMSS)

OBJECTIVES

Informal caregivers provide fundamental help to persons with multiple sclerosis through a variety of tasks ranging from practical assistance to psychological support. Caregiving Tasks in Multiple Sclerosis Scale (CTiMSS) is a reliable and valid measure assessing the complex structure of caregiving tasks within the context of multiple sclerosis. The present study was aimed to test the validity and reliability of the Italian translation of CTiMSS in a sample of informal caregivers of persons with multiple sclerosis.

METHODS

A total of 580 caregivers (51.4% women, aged 18-81, M = 46.47, SD = 12.8) together with their care recipients (63.1% women, aged 19-60, M = 40.08, SD = 9.9) were involved in this study. Exploratory and confirmatory factor analyses with a split-sample approach were employed to evaluate construct validity. Convergent and discriminant validity were assessed using correlation indices with scales from Short Form Health Survey-36 and Positive and Negative Affect Schedule. Cronbach's alphas were used as a measure of reliability.

RESULTS

Compared with the original CTiMSS 4-factor structure, a more stable and valid solution with 3 first-order factor loading on a single second-order factor was evaluated and confirmed; convergent and discriminant validity were also supported, and Cronbach's alpha values highlighted good-to-excellent reliability levels.

CONCLUSION

Results supported the validity and reliability of the Italian CTiMSS. Thanks to its ability to assess specific caregiving tasks, the measure can be a useful instrument for tailoring intervention focused on the promotion of both caregivers' and care recipients' quality of life.

Exercise and Multiple Sclerosis

Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system (CNS) with an estimated prevalence approaching 1 million adults in the United States. The disease pathogenesis and resulting damage express as dysfunction (e.g., walking and cognitive impairment) and symptoms (e.g., fatigue and depression) that compromise quality of life (QOL) and full participation. There has been a steadily increasing body of research on the outcomes of exercise among persons with MS, and this has accelerated sharply over the past decade. The current chapter provides a review of exercise and its outcomes, safety, and prescription in MS. This chapter initially reviews the evidence for benefits of exercise based principally on meta-analyses and literature reviews. The chapter then reviews evidence on the safety of exercise in MS and lastly provides guidelines for exercise prescription in MS. Collectively, this chapter serves as an overview and reference for researchers and clinicians interested in the benefits, safety, and prescription of exercise in MS.

Individualised behaviour change strategies for physical activity in multiple sclerosis (IPAC-MS): protocol for a randomised controlled trial

Background

Multiple sclerosis (MS) is a chronic, degenerative disease of the central nervous system. Because of the long-term and unpredictable nature of the disease, the burden of MS is significant from both a patient and societal perspective. Despite a recent influx of disease-modifying therapies to treat MS, many individuals continue to experience disability that negatively affects productivity and quality of life. Previous research indicates that physical activity has a positive impact on walking function in individuals with MS, in addition to the usual beneficial effects on overall health. However, most people with MS are not active enough to gain these benefits, and a lack of support to initiate and maintain physical activity has been identified as a major barrier. This study will evaluate the impact of a novel intervention involving individualised behaviour change strategies delivered by neurophysiotherapists on increasing physical activity levels in individuals with MS who are currently inactive.

Methods/design

This single-blind, parallel-group, randomised controlled trial will be conducted in Saskatchewan, Canada. Eligible participants include individuals with MS who are ambulatory but identified as currently inactive by the self-reported Godin Leisure-Time Exercise Questionnaire (GLTEQ). The intervention will be delivered by neurophysiotherapists and includes individualised behaviour change strategies aimed at increasing physical activity over a 12-month period. The control group will receive usual care during the 12-month study period. The primary outcome is the change in physical activity level, as measured by the change in the GLTEQ score from baseline to 12 months. Secondary outcomes include the change in patient-reported outcome measures assessing MS-specific symptoms, confidence and quality of life.

Discussion

Physical activity has been identified as a top research priority by the MS community. Findings from this novel study may result in new knowledge that could significantly impact the management and overall health of individuals with MS.

Informing the design of exercise programs for persons with multiple sclerosis who use wheelchairs: a qualitative inquiry of perceived components

PURPOSE

We investigated the perceptions of persons with multiple sclerosis (MS) who use wheelchairs regarding preferences for the design of exercise programs.

MATERIALS AND METHODS

We conducted online, semi-structured interviews with 20 persons with MS who use wheelchairs regarding preferences for exercise programs. We identified perceived necessary and desired components of exercise programs through deductive content analysis.

RESULTS

Participants articulated preferences for "what", "when", "where", and "who" of exercise programs for persons with MS who use wheelchairs. The majority of participants expressed an interest in aerobic and strength training, possibly supported by rehabilitation therapies (what). The frequency was 2-7 times per week with a duration of 15-30 minutes (when). The locations included home-, Internet-, or community-based exercise (where), supported through autonomous, one-on-one, and group delivery (who).

CONCLUSIONS

Persons with MS who use wheelchairs were interested in exercise, but need resources for engagement in regular exercise programs that yield meaningful health benefits. This study provided guidance for creating personalized, structured exercise programs for persons with MS who use wheelchairs that may improve overall wellness, independence, and quality of life.Implications for rehabilitationExercise training programs often do not account for the unique needs and wants of persons with multiple sclerosis (MS) who use a wheelchair.Personalized, structured exercise programs for persons with MS who use wheelchairs may improve outcomes including independence and quality of life.The proposed exercise guidelines provide initial guidance for persons with MS who use wheelchairs regarding engagement in exercise for improving MS symptoms and quality of life.

An E-Learning Program for Increasing Physical Activity Associated Behaviors Among People with Spinal Cord Injury: Usability Study

Background

The majority of people with spinal cord injury (SCI) in the United States are not meeting the recommended guidelines for regular physical activity. Behavior change techniques (eg, goal setting and action planning) that are framed within the principles of the social cognitive theory (self-efficacy and self-regulation) have the potential to enhance physical activity behavior.

Objective

The aim of the study was to develop and test the usability of an electronic learning (e-learning) program for improving social cognitive factors related to physical activity behavior among people with SCI.

Methods

The program was created through an iterative process of development and refinement, using a modification of a similar methodology used to develop evidence-informed guidelines in health promotion for people with disabilities (Guidelines, Recommendations, and Adaptations Including Disability; GRAIDs framework). The study included 4 phases: (1) initial product creation, (2) national survey, (3) expert review, and (4) usability testing. Usability testing included both quantitative and qualitative data collection and analyses.

Results

The review of the program by an expert panel (n=5) and the results from a national survey (n=142) led to several refinements. Usability testing demonstrated that the program could be completed in a timely manner (<30 min). Participants reported 5 themes: (1) the program improves social cognitions related to physical activity participation; (2) reflection of physical activity behavior; (3) positive perceptions of the quality of the program; (4) positive perceptions of the program operation and effectiveness; and (5) recommendations for improvement. Each item was incorporated into a revised program version 1.0.

Conclusions

This study incorporated an evidence-based framework for developing a brief 30-min e-learning program for increasing the physical activity behavior among people with SCI. The Exercise Strategies Through Optimized Relevant Interactive E-learning Storytelling (e-STORIES) program could be completed in a timely manner and was reported by participants as valuable and useful for enhancing intent-to-perform physical activity in individuals with SCI. The program has the potential to be applied in a variety of settings, but feasibility testing is required before implementing in a larger trial.

Sport Intervention Programs (SIPs) to Improve Health and Social Inclusion in People with Intellectual Disabilities: A Systematic Review

Inactivity is a major issue that causes physical and psychological health problems, especially in people with intellectual disability (ID). This review discusses the beneficial effects of sport intervention programs (SIPs) in people with ID, and aims to provide an overview of the scientific literature in order to identify the main factors influencing the participation of people with ID in SIPs. Twelve papers were analyzed and compared. The results show a large variety in examined SIPs, concerning participants' age and disability, intervention characteristics and context, as well as measures and findings. The main factors essential for people with ID partaking in SIPs appeared to be suitable places for the SIP development, adequate implementation of physical activity (PA) programs in school and extra-school contexts, education, and the training of teachers and instructors. The literature review highlights the relevance of using SIPs in order to improve physical and psychological health, as well as increase social inclusion in populations with ID. SIPs should be included in multifactor intervention programs. Nevertheless, the need is recognized for stakeholders to adopt specific practice and policy in promoting social inclusion in order to organize intervention strategies which are able to provide quality experiences in sport and physical activity for people with ID.

Exercise Training Guidelines for Multiple Sclerosis, Stroke, and Parkinson Disease: Rapid Review and Synthesis

The translation of knowledge from exercise training research into the clinical management of multiple sclerosis, stroke, and Parkinson disease requires evidence-based guidelines that are uniformly recognizable by healthcare practitioners and patients/clients. This article synthesized resources that reported aerobic and resistance training guidelines for people with multiple sclerosis, stroke, and Parkinson disease. Systematic searches yielded 25 eligible resources from electronic databases and Web sites or textbooks of major organizations. Data were extracted (exercise frequency, intensity, time, and type) and synthesized into three sets of recommendations. Exercise guidelines for multiple sclerosis consistently recommended 2-3 d/wk of aerobic training (10-30 mins at moderate intensity) and 2-3 d/wk of resistance training (1-3 sets between 8 and 15 repetition maximum). Exercise guidelines for stroke recommended 3-5 d/wk of aerobic training (20-40 mins at moderate intensity) and 2-3 d/wk of resistance training (1-3 sets of 8-15 repetitions between 30% and 50% 1 repetition maximum). Exercise guidelines for Parkinson disease recommended 3-5 d/wk of aerobic training (20-60 mins at moderate intensity) and 2-3 d/wk of resistance training (1-3 sets of 8-12 repetitions between 40% and 50% of 1 repetition maximum). This harmonization of exercise guidelines provides a prescriptive basis for healthcare providers, exercise professionals, and people with multiple sclerosis, stroke, and Parkinson disease regarding exercise programming.

Rationale and design of the STEP for MS Trial: Comparative effectiveness of Supervised versus Telerehabilitation Exercise Programs for Multiple Sclerosis

BACKGROUND

We propose a Phase III trial that compares the effectiveness of an exercise training program delivered in a facility-based setting with direct, in-person supervision or a home-based setting with remote supervision via telerehabilitation for improving walking performance in persons with multiple sclerosis(MS) who have walking dysfunction and mobility disability.

METHODS/DESIGN

The study was developed with stakeholder engagement and is a multi-site trial that follows a 2-stage, randomized choice design. The trial compares the effectiveness of a 16-week evidence-based, individualized exercise program delivered in a supervised, facility-based setting versus a remotely coached/guided, home-based setting using telerehabilitation in physically inactive and cognitively intact people with MS who have walking dysfunction and mobility disability(N = 500). The primary outcome is walking speed. The secondary outcomes are walking endurance, disability status, and patient-reported outcomes of physical activity, walking impairment, fatigue, and quality of life. The components of the exercise program itself are similar between the groups and follow the Guidelines for Exercise in MS protocol. This includes a program manual, exercise prescription, exercise equipment, social-cognitive theory materials including newsletters, logs, and calendars, and one-on-one behavioral coaching by exercise specialists with background in MS. The main difference between groups is the coaching approach and setting for delivering the exercise training program. The outcomes will be collected by treatment-blinded assessors at baseline(week 0), mid-intervention(week 8), post-intervention(week 16), and follow-up(week 52).

DISCUSSION

The proposed study will provide evidence for the effectiveness of a novel, widely-scalable program for delivering exercise training in persons with MS who have walking dysfunction and mobility disability.

Sociodemographic and clinical correlates of device-measured sedentary behaviour in multiple sclerosis

PURPOSE

This study examined sociodemographic and clinical variables as correlates of device-measured volume and pattern of sedentary behaviour in persons with multiple sclerosis (MS).

MATERIALS AND METHODS

Participants were recruited through a standardised invitation letter distributed among 1000 persons randomly selected from the North American Research Committee on MS registry. Those who volunteered wore an accelerometer for 7 d and provided sociodemographic and clinical information.

RESULTS

There were 233 persons with MS who were included in the analyses. Linear regression analyses indicated that age and MS type explained significant variance in total sedentary time per day as well as number of breaks in sedentary time. Only disability status explained significant variance in sedentary bout length, whereas age explained significant variance in both number of long sedentary bouts per day. Both age and disability status explained significant variance total time spent in long sedentary bouts per day.

CONCLUSIONS

Persons of older age, progressive MS, and higher disability status spend prolonged, uninterrupted periods of time sedentary. Such results highlight the need for targeted interventions in sub-populations of MS that reduce time spent sedentary and break up the pattern of sedentary behaviour. Implications for Rehabilitation Sedentary behaviour is highly prevalent in multiple sclerosis and may be associated with comorbid conditions. The majority of research on sedentary behaviour in multiple sclerosis has been derived from self-report instruments that only measure the volume of sitting time per day. This study indicates that persons with multiple sclerosis spend a significant amount of time sedentary, and those who are older, have progressive multiple sclerosis, and have higher disability status spend prolonged, uninterrupted periods of time sedentary. Such results highlight the need for targeted behavioural interventions in these sub-populations of multiple sclerosis to reduce time spent sedentary and break the pattern of sedentary behaviour to manage its consequences.

An Intervention for Changing Sedentary Behavior Among African Americans With Multiple Sclerosis: Protocol

BACKGROUND

Sedentary behavior is a major concern among patients with multiple sclerosis (MS), as it may accelerate disease progression and exacerbate physical disability. This is especially concerning among African Americans, a segment of the MS population who present with greater neurological disability and higher odds of physical comorbidities than their Caucasian counterparts.

OBJECTIVE

To date, researchers have not proposed interventions that focus on changing sedentary behavior in African Americans with MS.

METHODS

This paper describes a pilot study that examines the feasibility and efficacy of using text messaging along with theory-driven newsletters and behavioral coaching for changing sedentary behavior in African Americans with MS. We herein present the methods, procedures, and outcomes for our ongoing study.

RESULTS

Enrollment began in February 2018 and is expected to conclude in April 2019. Study results will be reported in the fall of 2019.

CONCLUSIONS

After completion of this pilot intervention, we will summarize our study results in manuscripts for publication in peer-reviewed journals that will provide critical information on the feasibility and efficacy of our strategy. These results will inform future studies and, potentially, larger interventions for remotely reducing sedentary behavior in African Americans with MS.

A Mobile App to Promote Adapted Exercise and Social Networking for People With Physical Disabilities: Usability Study

BACKGROUND

People with physical disabilities (PWD) experience several unique challenges that prevent them from participating in onsite exercise programs. Although mobile apps can provide a ubiquitous channel for delivering convenient exercise services within the community, no exercise apps have been designed for people with disabilities who experience certain functional limitations.

OBJECTIVE

The aim of this study was to examine the usability of a mobile exercise app in PWD.

METHODS

A sequential explanatory mixed-method design was used to holistically test usability in 4 core areas: effectiveness (ie, ease of use), efficiency (ie, operation speed), perceived satisfaction, and usefulness. Participants completed 7 face-to-face usability tasks and 1 structured interview. Equipment included a computer tablet that came preinstalled with the exercise app. The app included exercise videos that focused on several components of fitness: aerobic capacity, muscular strength, functional strength or balance, and range of motion. The app contained 3 different versions of the exercise program: (1) a program for people with the ability to use the upper and lower limbs, (2) a seated program for people with the ability to use only upper limbs, and (3) a program designed for people with hemiparesis. The app also included educational resources in the form of infographics aimed at addressing key social cognitive theory constructs included social support, outcome expectancies, self-efficacy, and barriers or facilitators to exercising. Participant characteristics and quantitative usability data were descriptively reported. Qualitative data were analyzed using thematic analysis.

RESULTS

A total of 12 PWD tested the usability of the exercise app and completed 96% (69/72) of the usability tasks on the first attempt. Operation speed varied among users, which prompted the development team to make minor revisions to the app. Qualitative results demonstrated 3 overarching themes: facilitates exercise adoption, positive experiences of videos, and easy to learn. Participants noted that the app circumvented several barriers to exercise associated with leaving the home (eg, inclement weather conditions, exacerbations of health conditions or disability symptoms, difficulties with transportation, and social support).

CONCLUSIONS

The mobile exercise app provided a simple platform that was effective, useful, and appreciated by PWD. Participants also perceived the app as easy to use and felt it was a valuable tool for assisting PWD to obtain regular exercise. Study findings also offered insight into the participants' preferences for mobile exercise apps that can aid future research and development projects. Future exercise trials are needed to determine the true impact of mobile app technology on lifestyle physical activity in people with disabilities.

Preferences for exercise among black individuals with multiple sclerosis

Background

The promotion of exercise among black individuals with multiple sclerosis (MS) is important for managing the functional and symptomatic manifestations of MS.

Objective

The objective of this study was to elicit exercise program preferences among black individuals with MS.

Methods

Participants completed a survey delivered through Qualtrics. The survey measured exercise program component preferences, the importance of racial considerations, and barriers and facilitators to exercise participation.

Results

Forty black individuals with MS completed the survey and reported a preference for five days per week (range 0–7) of exercise at a moderate intensity (50% of the sample). Over 60% of participants desired an exercise program that was longer than six months, and over half wanted the aid of a behavioral coach. Participants preferred weight/resistance training exercises (52.5%) and easy walking (35%) modalities. The outcomes expected from exercise were increased muscle strength (65%) and improved overall body functioning (60%). The anticipated barriers for exercise were largely fatigue (40%) and time management (32.5%). The desired facilitators were a personal trainer (57.5%) and more exercise information (32.5%). Cultural and racial tailoring was very important or held some importance on the components of the program.

Conclusion

The findings of this study should be considered when developing exercise interventions for black individuals with MS.

eHealth-Based Behavioral Intervention for Increasing Physical Activity in Persons With Multiple Sclerosis: Fidelity Protocol for a Randomized Controlled Trial

Background

The rate of physical activity is substantially lower in persons with multiple sclerosis (MS) than in the general population. This problem can be reversed through rigorous and reproducible delivery of behavioral interventions that target lifestyle physical activity in MS. These interventions are, in part, based on a series of phase II randomized controlled trials (RCTs) supporting the efficacy of an internet-delivered behavioral intervention, which is based on social cognitive theory (SCT) for increasing physical activity in MS.

Objective

This paper outlines the strategies and monitoring plan developed based on the National Institutes of Health Behavior Change Consortium (NIH BCC) treatment fidelity workgroup that will be implemented in a phase III RCT.

Methods

The Behavioral Intervention for Physical Activity in Multiple Sclerosis (BIPAMS) study is a phase III RCT that examines the effectiveness of an internet-delivered behavioral intervention based on SCT and is supported by video calls with a behavioral coach for increasing physical activity in MS. BIPAMS includes a 6-month treatment condition and 6-month follow-up. The BIPAMS fidelity protocol includes the five areas outlined by the NIH BCC. The study design draws on the SCT behavior-change strategy, ensures a consistent dose within groups, and plans for implementation setbacks. Provider training in theory and content will be consistent between groups with monitoring plans in place such as expert auditing of calls to ensure potential drift is addressed. Delivery of treatment will be monitored through the study website and training will focus on avoiding cross-contamination between conditions. Receipt of treatment will be monitored via coaching call notes and website monitoring. Lastly, enactment of treatment for behavioral and cognitive skills will be monitored through coaching call notes among other strategies. The specific strategies and monitoring plans will be consistent between conditions within the constraints of utilizing existing evidence-based interventions.

Results

Enrollment began in February 2018 and will end in September 2019. The study results will be reported in late 2020.

Conclusions

Fidelity-reporting guidelines provided by the NIH BCC were published in 2004, but protocols are scarce. This is the first fidelity-monitoring plan involving an electronic health behavioral intervention for increasing physical activity in MS. This paper provides a model for other researchers utilizing the NIH BCC recommendations to optimize the rigor and reproducibility of behavioral interventions in MS.

Characteristics of Adults With Neurologic Disability Recruited for Exercise Trials: A Secondary Analysis

This review examined demographic and clinical characteristics of participants from exercise trials in 3 neurologic disability conditions (multiple sclerosis, spinal cord injury, and traumatic brain injury) and compared these data with population-based statistics. The authors included 75 published studies from 2006 to 2016: 53 studies for multiple sclerosis (n = 2,034), 14 for spinal cord injury (n = 302), and 8 for traumatic brain injury (n = 272). Pooled data resembled some heterogeneous aspects of population data sets. However, many characteristics were not reported; samples were small and predominantly White, and 48.1% of the people screened were excluded. Thus, findings from these studies may not be translatable across the range of people with these three conditions, which warrant efforts to target the inclusion of underrepresented subgroups in future exercise trials.

Exploring the uptake and implementation of tele-monitored home-exercise programmes in adults with Parkinson's disease: A mixed-methods pilot study

BACKGROUND

People with Parkinson's disease experience numerous barriers to exercise participation at fitness facilities. Advances in tele-monitoring technologies create alternative channels for managing and supervising exercise programmes in the home. However, the success of these programmes will depend on participants' perceptions of using the technology and their exercise adherence. Thus, this pilot explored the uptake and implementation of two common methods of Internet-exercise training in Parkinson's disease.

METHODS

Twenty adults with Parkinson's disease were randomized into either: telecoach-assisted exercise (TAE) or self-regulated exercise (SRE) groups. Both groups received the same eight-week exercise prescription (combined strength and aerobic exercise) and telehealth system that streamed and recorded vital signs and exercise data. TAE participants exercised under a telecoach's supervision via videoconferencing. SRE participants independently managed their exercise training. Quantitative data were described and qualitative data underwent thematic analysis.

RESULTS

Quantitative results demonstrated that TAE participants achieved strong attendance (99.2%), whereas SRE participants demonstrated 35.9% lower attendance, 48% less total time exercising, and 74.5% less time exercising at moderate intensity. Qualitatively, TAE participants reported overtly favourable programme experiences and that assistance from a telecoach enhanced their exercise motivation. SRE participants noted several challenges that impeded adherence.

CONCLUSION

Findings demonstrate that adults with Parkinson's disease acknowledge benefits of exercising through a telehealth system and are open to utilizing this channel as a means of exercise. However, human-interactive support may be required to overcome unique impediments to participation. Study findings warrant validation in larger trials that can transfer the success of TAE towards more scalable methods of delivery.

Pilot randomized trial of a telephone-delivered physical activity and weight management intervention for individuals with lower extremity amputation

BACKGROUND

Obesity and inactivity are common and burdensome for people with lower extremity amputation (LEA). The extent to which home-based physical activity/weight management programs are effective and safe for people with LEA is unknown. Translating effective interventions for understudied disability groups is needed.

OBJECTIVE

To test the feasibility, acceptability, and safety of a weight management and physical activity intervention and obtain preliminary efficacy estimates for changes in weight, body composition, and physical functioning.

METHODS

Eligibility criteria included: LEA ≥1 year prior, 18-69 years of age, overweight or obese and living in the Seattle area. The intervention arm received self-monitoring tools (e.g., pedometer, scale) and written materials, a single exercise counseling home visit by a physical therapist, and up to 11 telephone calls from a health coach over 20 weeks that involved motivational interviewing to set specific, attainable, and measurable goals. The self-directed control group received the same tools and materials but no home visit or coaching calls.

RESULTS

Nineteen individuals consented to participate, 15 were randomized (mean age = 56, 73% male, 80% transtibial amputation) and 11 completed 20-week follow-up assessments. The intervention was acceptable and safe. Coached participants had greater decreases in waist circumference (mean difference between groups over 20 weeks, baseline values carried forward: -4.3 cm, 95% CI -8.2, -0.4, p = 0.03) and fat mass (-2.1 kg, 95% CI -3.8, -0.4, p = 0.02).

CONCLUSIONS

The home-based intervention was promising in terms of efficacy, safety and acceptability. Inclusion of multiple trial centers and increased use of technology may facilitate recruitment and retention.

Phase-III, randomized controlled trial of the behavioral intervention for increasing physical activity in multiple sclerosis: Project BIPAMS

BACKGROUND

We propose a phase-III, randomized controlled trial (RCT) that examines the effectiveness of a behavioral intervention based on social cognitive theory (SCT) and delivered through the Internet using e-learning approaches for increasing physical activity and secondary outcomes (e.g., symptoms) in a large sample of people with multiple sclerosis (MS) residing throughout the United States.

METHODS/DESIGN

The proposed phase-III trial will use a parallel group, RCT design that examines the effect of a 6-month behavioral intervention for increasing physical activity and secondarily improving mobility, cognition, symptoms, and quality of life (QOL) in persons with MS. The primary outcome is accelerometer-measured moderate-to-vigorous physical activity (MVPA). The secondary outcomes include self-report measures of physical activity, walking impairment, cognition, fatigue, depression, anxiety, pain, sleep quality, and QOL. The tertiary outcomes are mediator variables based on SCT. Participants (N = 280) will be randomized into behavioral intervention (n = 140) or attention and social contact control (n = 140) conditions using computerized random numbers with concealed allocation. The conditions will be administered over 6-months by persons who are uninvolved in screening, recruitment, random assignment, and outcome assessment. There will be a 6-month follow-up without intervention access/content. We will collect primary, secondary, and tertiary outcome data every 6 months over the 12-month period. Data analysis will involve intent-to-treat principles and latent growth modeling (LGM).

DISCUSSION

The proposed research will provide evidence for the effectiveness of a novel, widely scalable approach for increasing lifestyle physical activity and improving secondary outcomes and QOL in persons with MS.

Promotion of physical activity and exercise in multiple sclerosis: Importance of behavioral science and theory

There is an obvious disconnect between evidence of benefits and rates of participation in exercise and physical activity among people living with multiple sclerosis (MS). We propose that the problem with exercise behavior in MS (i.e. lack of broad or increasing participation by people with MS despite evidence of meaningful benefits) might be ameliorated through the inclusion of behavior change theory in the design of exercise programs and promotion efforts, as has been undertaken in other populations such as breast cancer survivors. This paper reviews Social Cognitive Theory as an example approach for informing interventions for increasing exercise and physical activity behavior outside of MS and provides an overview of current knowledge regarding the application of this theory for physical activity in MS. We then outline future research necessary for informing trials that design, implement, and test theory-based interventions for physical activity promotion in MS. If theories of behavior change are adopted for informing exercise and physical activity research in MS, we can take a major step forward in addressing the problem of exercise and physical activity participation that has plagued the field for more than 25 years.

Development of an intervention to stimulate physical activity in hard-to-reach physically disabled people and design of a pilot implementation: an intervention mapping approach

INTRODUCTION

Physically disabled people are less physically active compared with healthy people. Existing physical activity (PA) interventions are limited in reach, since they are primarily rehabilitation or school based. The current study aims to develop a community-based intervention for stimulating PA in hard-to-reach physically disabled people.

METHODS AND ANALYSIS

To systematically develop a PA-stimulating intervention, intervention mapping (six steps) was applied. PA level and health-related quality of life of patients after rehabilitation was determined using questionnaires (step 1). Qualitative research was performed to study professionals' and physically disabled people's ideas about intervention objectives, determinants and design (steps 2 and 3). Since experts expressed no need for a new intervention, the existing intervention 'Activity coach' was adapted to the specific target population. The adapted intervention 'Activity coach+' composes a network of intermediate organisations that refers participants to an activity coach, who coaches participants during 1 year. After a preintervention physical assessment by a physiotherapist, participants will be individually guided to existing organised or non-organised activities. An activity tracker will be used to monitor and stimulate PA in daily life (step 4). To support adoption and implementation, meetings between involved parties are organised (step 5). 'Activity coach+' is implemented in community in March 2017, and will be evaluated using a mixed-method analysis. Quantitative evaluation of intervention effects on PA, health and social participation takes place after 0, 2, 4, 6 and 12 months. The implementation process and experiences with the intervention will be determined using qualitative research (step 6).

ETHICS AND DISSEMINATION

Insights from this study will be used for dissemination and further development of the intervention. The Medical Ethical Committee of the University Medical Center Groningen confirmed that formal ethical approval was not required (METc 2016/630).

Sustainability of exercise intervention outcomes among people with disabilities: a secondary review

BACKGROUND

This review explored the sustainability of health and physical activity-based outcomes following exercise trials that were conducted for people with disabilities, and characterised the influence of technology and behaviour change strategies.

METHODS

A total of 132 studies were screened from an existing database.

RESULTS

Only 22 studies featured follow-up periods and met eligibility criteria. At follow-up, studies typically reported at least one significant health outcome that was maintained (n = 18/21; 86%). However, significant health outcomes accounted for only 32% of the total volume of outcomes that were measured at follow-up. For physical activity-based outcomes, six studies (n = 6/8; 75%) reported that intervention gains were maintained throughout follow-up. The incorporation of technology or behaviour change strategies appeared to be linked with sustainable intervention effects.

CONCLUSIONS

Overall, some evidence demonstrated that post-intervention effects were sustainable. However, the strength of the evidence was weak and several existing gaps in knowledge were identified. Moreover, most studies did not focus on sustainability, but instead emphasised short-term effects of exercise participation on health and physical activity outcomes. Study findings call for greater research and programme efforts to maintain health, function, and physical activity behaviour after supports provided by research studies are removed. Implications for rehabilitation Short-term exercise programmes may require additional strategies designed specifically to enhance the sustainability of exercise outcomes and physical activity participation. Incorporating technology within exercise interventions may enhance the likelihood of sustaining health and function outcomes. Exercise programmes framed within behaviour change theory can equip individuals with the appropriate strategies necessary to maintain their physical activity participation.

Use of the Godin leisure-time exercise questionnaire in multiple sclerosis research: a comprehensive narrative review

PURPOSE

The Godin Leisure-Time Exercise Questionnaire has been a commonly applied measure of physical activity in research among persons with multiple sclerosis over the past decade. This paper provides a comprehensive description of its application and inclusion in research on physical activity in multiple sclerosis.

METHOD

This comprehensive, narrative review included papers that were published between 1985 and 2017, written in English, involved participants with multiple sclerosis as a primary population, measured physical activity, and cited one of the two original Godin papers.

RESULTS AND CONCLUSION

There is a broad scope of research that has included the Godin Leisure-Time Exercise Questionnaire in persons with multiple sclerosis. Overall, 8 papers evaluated its psychometric properties, 21 evaluated patterns of physical activity, 24 evaluated correlates or determinants of physical activity, 28 evaluated outcomes or consequences of physical activity, and 15 evaluated physical activity interventions. The Godin Leisure-Time Exercise Questionnaire is a valid self-report measure of physical activity in persons with multiple sclerosis, and further is an appropriate, simple, and effective tool for describing patterns of physical activity, examining correlates and outcomes of physical activity, and provides a sensitive outcome for measuring change in physical activity after an intervention. Implications for rehabilitation There is increasing interest in physical activity and its benefits in multiple sclerosis. The study of physical activity requires appropriate and standardized measures. The Godin Leisure-Time Exercise Questionnaire is a common self-report measure of physical activity for persons with multiple sclerosis. Godin Leisure-Time Exercise Questionnaire scores are reliable measures of physical activity in persons with multiple sclerosis. The Godin Leisure-Time Exercise Questionnaire further is an appropriate, simple, and effective tool for describing patterns of physical activity, examining correlates and outcomes of physical activity participation, and is an advantageous primary outcome for measuring change in physical activity in response to an intervention.

Motion sensors in multiple sclerosis: Narrative review and update of applications

INTRODUCTION

The use of motion sensors for measuring physical activity in multiple sclerosis (MS) has evolved with increasing research particularly during the past decade. Areas covered: This manuscript reviews the literature regarding the application of motion sensors for measuring physical activity in MS. We first describe 'what is known' about their use in MS by examining the evidence generated between 1997 and 2012, including the psychometric properties of motion sensors in MS and the development of MS-specific accelerometer cut-points. We then evaluate 'what is new' based on research conducted between 2013 and 2017. This includes newer research on psychometric properties of motion sensors in MS, development of new MS-specific accelerometer and step-rate cut-points, sedentary behavior assessment, and research on fitness trackers and multisensors in MS. The final part presents a picture of 'what is next' for the applications of motion sensors in MS, especially pertaining new opportunities for testing and using fitness trackers in MS, and tracking disease and disability progression based on motion sensor output. Expert commentary: The use of motion sensors in MS has grown substantially over the years; however, a lot more can be done to explore the full potential and utility of these devices in MS.

Randomized controlled trial of an e-learning designed behavioral intervention for increasing physical activity behavior in multiple sclerosis

BACKGROUND

Internet-delivered, behavioral interventions represent a cost-effective, broadly disseminable approach for teaching persons with multiple sclerosis (MS) the theory-based skills, techniques, and strategies for changing physical activity.

OBJECTIVES

This pilot, randomized controlled trial examined the efficacy of a newly developed Internet website based on e-learning approaches that delivered a theory-based behavior intervention for increasing physical activity and improving symptoms, walking impairment, and neurological disability.

METHODS

Participants with MS (N = 47) were randomly assigned into behavioral intervention (n = 23) or waitlist control (n = 24) conditions delivered over a six-month period. Outcomes were administered before and after the six-month period using blinded assessors, and data were analyzed using analysis of covariance in SPSS.

RESULTS

There was a significant, positive intervention effect on self-reported physical activity (P = 0.05, [Formula: see text] = 0.10), and non-significant improvement in objectively measured physical activity (P = 0.24, [Formula: see text] = 0.04). There were significant, positive effects of the intervention on overall (P = 0.018, [Formula: see text] = 0.13) and physical impact of fatigue (P = 0.003, [Formula: see text] = 0.20), self-reported walking impairment (P = 0.047, [Formula: see text] = 0.10), and disability status (P = 0.033, [Formula: see text] = 0.11). There were non-significant improvements in fatigue severity (P = 0.10, [Formula: see text] = 0.06), depression (P = 0.10, [Formula: see text] = 0.07) and anxiety (P = 0.06, [Formula: see text] = 0.09) symptoms, and self-reported disability (P = 0.10, [Formula: see text] = 0.07).

CONCLUSIONS

We provide evidence for the efficacy of an Internet-based behavioral intervention with content delivered through interactive video courses grounded in e-learning principles for increasing physical activity and possibly improving secondary outcomes of fatigue, depression, anxiety, and walking impairment/disability in persons with MS.
