Internet-delivered behavioral intervention to increase physical activity in persons with multiple sclerosis: sustainability and secondary outcomes

Functional outcomes of diets in multiple sclerosis (FOOD for MS): Protocol for a parallel arm randomized feeding trial for low glycemic load and calorie restriction

BACKGROUND

Pilot trials indicate that both a low glycemic load (GL) diet and calorie restriction (CR) can be implemented successfully in people with multiple sclerosis (pMS) and may improve MS symptoms and physical function, but large randomized clinical trials (RCTs) have not yet been conducted. The purpose of this study is to test these interventions alone and in combination to determine their efficacy for improving clinical and patient reported outcomes (PROs) in pMS.

METHODS

This 32-week, two-arm, RCT at two centers will randomly assign 100 adults with relapsing-remitting or secondary progressive MS to a low GL diet (n = 50) or a standard GL diet (n = 50). Both diet groups will complete two study phases: a eucaloric phase (16 weeks) and a CR phase (16 weeks). Groceries for the study meal plans will be delivered to participants' homes weekly. The primary outcome is physical function, measured by timed 25-ft walk test. Secondary outcomes are pain, fatigue, mood, and anxiety.

DISCUSSION

This will be the most rigorous intervention trial to date of a low GL diet and CR in adults with MS, and among the first to assess the impact of intentional weight loss on MS symptoms. Results will provide valuable insight for recommending dietary change, weight loss, or both to adults with MS. These non-drug interventions pose few risks and have potential to yield significant improvements in MS symptoms.

Study protocol: exercise training for treating major depressive disorder in multiple sclerosis

BACKGROUND

Major depressive disorder (MDD) is prevalent, yet sub-optimally treated among persons with multiple sclerosis (MS). We propose that exercise training may be a promising approach for treating depression in persons with MS who have MDD. Our primary hypothesis predicts a reduction in depression severity immediately after an exercise training intervention compared with minimal change in an attention control condition, and the reduction will be maintained during a follow-up period.

METHODS

This study involves a parallel-group, assessor-blinded RCT that examines the effect of a 4-month home-based exercise training intervention on depression severity in a sample of persons with MS who have MDD based on the MINI International Neuropsychiatric Interview. The primary outcomes of depression severity are the Patient Health Questionnaire-9 and Hamilton Depression Rating Scale. Participants (N = 146) will be recruited from within 200 miles of the University of Illinois at Chicago and randomized (1:1) into either a home-based exercise training condition or control condition with concealed allocation. The exercise training and social-contact, attention control (i.e., stretching) conditions will be delivered remotely over a 4-month period and supported through eight, 1:1 Zoom-based behavioral coaching sessions guided by social-cognitive theory and conducted by persons who are uninvolved in screening, recruitment, random assignment, and outcome assessment. We will collect outcome data at 0, 4 and 8 months using treatment-blinded assessors, and data analyses will involve intent-to-treat principles.

DISCUSSION

If successful, the proposed study will provide the first Class I evidence supporting a home-based exercise training program for treating MDD in persons with MS. This is critical as exercise training would likely have positive secondary effects on symptoms, cognition, and quality of life, and provide a powerful, behavioral approach for managing the many negative outcomes of MDD in MS. The program in the proposed research is accessible and scalable for broad treatment of depression in MS, and provides the potential for integration in the clinical management of MS.

The trial was registered on September 10, 2021 at clinicaltrials.gov with the identifier NCT05051618. The registration occurred before we initiated recruitment on June 2, 2023.

Updated Systematic Review and Quantitative Synthesis of Physical Activity Levels in Multiple Sclerosis

OBJECTIVE

This article provided an updated quantitative synthesis of physical activity levels in persons with multiple sclerosis compared with controls and other clinical populations.

DESIGN

A systematic search through PubMed, Scopus, and PsycINFO was conducted for articles published between August 2016 and July 2022. Articles that included a group comparison of at least one measurement of physical activity between adults with multiple sclerosis and controls or other clinical populations were included in the meta-analysis.

RESULTS

Twenty-four studies met the inclusion criteria and yielded a total of 119 comparisons. There was a moderate difference in physical activity levels between persons with multiple sclerosis and controls (effect size = -0.56, P < 0.01), but no significant difference between persons with multiple sclerosis and other clinical populations (effect size = 0.01, P = 0.90). The pooled effect sizes comparing multiple sclerosis with controls ( Q104 = 457.9, P < 0.01) as well as with clinical populations ( Q13 = 108.4, P < 0.01) were heterogeneous. Moderating variables included sex, disability status, measurement method, outcome, intensity, and application of a multiple sclerosis-specific cut-point.

CONCLUSIONS

Physical activity levels remain significantly lower in persons with multiple sclerosis compared with controls, but the magnitude of difference has become smaller over the past decade. There is a need for continued development of effective physical activity programs that can reach the greater community with multiple sclerosis.

Randomized Controlled Trial of the Behavioral Intervention for Physical Activity in Multiple Sclerosis Project: Response Heterogeneity and Predictors of Change

BACKGROUND

We reported that a social cognitive theory-based (SCT), Internet-delivered behavioral intervention increased device-measured minutes/day of moderate-to-vigorous physical activity (MVPA) over a 6-month period among persons with multiple sclerosis (MS). This paper examined the pattern and predictors of heterogeneity in change for MVPA. Based on previous research, we hypothesized that mild MS disability, fewer MS symptoms, lower baseline MVPA, and positive SCT characteristics (e.g., high exercise self-efficacy) would be associated with greater change in MVPA.

METHOD

Persons with MS (N = 318) were randomized into behavioral intervention (n = 159) or attention/social contact control (n = 159) conditions that were administered via Internet websites and supported with behavioral coaching. Demographic, clinical, symptom, behavioral, and SCT data were from before the 6-month period of delivering the conditions, and MVPA data were from before and after the 6-month period. We examined heterogeneity based on waterfall plots, box plots, and the Levene statistic. We identified predictors of MVPA change using bivariate correlation and multiple, linear regression analyses per condition.

RESULTS

The Levene statistic indicated statistically significant heterogeneity of variances for MVPA change between conditions (p = .003), and the waterfall plots and box plots indicated greater heterogeneity in MVPA change for the behavioral intervention. MVPA change score was correlated with baseline MVPA (r =  - .33 and r =  - .34, p = .0004 and p = .0001) in both conditions and walking impairment (r =  - .188, p = .047) and race (r = .233, p = .014) in the behavioral intervention condition. The regression analysis indicated that baseline MVPA (Standardized B =  - .449, p = .000002), self-reported walking impairment (Standardized B =  - .310, p = .0008), and race (Standardized B = .215, p = .012) explained 25.6% of variance in MVPA change for the behavioral intervention condition.

CONCLUSION

We provide evidence for walking impairment, baseline MVPA, and race as predictors of the heterogeneity in the pattern of MVPA change with a behavioral intervention.

Effects of home-based virtual reality telerehabilitation system in people with multiple sclerosis: A randomized controlled trial

BACKGROUND AND OBJECTIVE

Multiple sclerosis is an inflammatory and neurodegenerative disorder of the central nervous system that can lead to severe motor disability. The aim of this study was to verify the health care effects of an integrated telerehabilitation approach involving dual-domains (motor and cognitive) in people with multiple sclerosis using a virtual reality rehabilitation system compared to a home-based conventional rehabilitative intervention usual care for patient-relevant outcomes (motor, cognitive and participation).

METHODS

This multicentre interventional, randomized controlled trial included 70 participants with multiple sclerosis, 35 in the telerehabilitation group (30 sessions of home-based virtual reality rehabilitation system training, five sessions for week each lasting 45 min) and 35 in the usual care group (30 sessions of conventional treatment, five sessions for week). Participants completed the assessment of motor, cognitive and participation outcomes at baseline and after 6 weeks of treatment.

RESULTS

In total, 63.3% of the telerehabilitation group exhibited improvement in the physical domain of the quality of life (p = 0.045). The telerehabilitation group showed greater improvement than the usual care group in Mini-BESTest domains of balance (p = 0.014), postural control (p = 0.024), and dynamic walking (p = 0.020) at post-treatment. Higher adherence was registered for telerehabilitation compared with usual care (86.67% vs. 80.0%).

DISCUSSION

This study provides evidence that people with multiple sclerosis can benefit from telerehabilitation treatment in the physical domain of the quality of life and motor symptoms. Moreover, considering the persistent COVID-19 emergency, telerehabilitation can represent an effective telemedicine solution for safely delivering effective rehabilitation care to people with multiple sclerosis.

Participants' perspectives of "NeuroSask: Active and Connect"-a virtual chronic disease management program for individuals with a neurological condition

Introduction

Neurological conditions account from more than half of Canadians requiring chronic care. Both physical activity and the development of a self-management skillset are critical components supporting individuals with chronic health conditions. "NeuroSask: Active and Connected" is a virtual chronic disease management program offering twice weekly neuro-physiotherapist directed "active" exercise sessions, followed by weekly knowledge-exchange "connect" sessions with invited guest experts. NeuroSask was launched April 2020 in response to the restricted services and supports for people with neurological conditions. The program aimed to provide seated physical activity, social interaction, and access to expertise in neurological conditions and neurorehabilitation. A program evaluation of NeuroSask was conducted to gain participants' perspectives.

Methods

All participants registered for the NeuroSask program were invited to complete optional online surveys (SurveyMonkey) circulated by email at 3 occasions post-program launch: 10 weeks, 1 year, and 2 years. Participants could complete any one or all of the surveys, at their discretion. The number of potential respondents changed dependent on the total number of participants registered for NeuroSask at the time the survey was circulated. Questions were co-designed by multi-stakeholder team members. Descriptive statistics were used for closed-ended questions and a reflexive thematic analysis was completed with coding conducted in NVivo 12 Plus for open-ended text.

Results

Response rates (participants/registrants) were as follows: 10-week survey 260/793, one year survey 326/1224, and 2-year survey 434/1989. 90% of participants reported being in either the age categories of 40-59 years or above 60 years. 75% of both survey respondents and program registrants were female. 70% of both survey respondents and program registrants reported a diagnosis of multiple sclerosis and 30% reported other neurological conditions. Survey respondents were from all ten Canadian provinces, with 45% reporting living outside of large cities. Respondents reported preferring online vs. in person format for this type of programming. Three main themes, and eight corresponding subthemes were identified highlighting the perceived impact and key components of the NeuroSask program: Theme 1 "together in a positive and encouraging environment" (subthemes 1a: connection, 1b: empowerment); Theme 2 "access to enthusiastic qualified leaders from home" (subthemes 2a: leader characteristics, 2b: accessibility, 2c: program logistics); Theme 3 "being able to enjoy everyday life" (subthemes 3a: symptom benefits and beyond, 3b: carry-over, 3c: keep going, please do not cancel).

Conclusion

NeuroSask is an example of an accessible and meaningful virtual approach to providing ongoing support for some individuals with neurological conditions. It was perceived as beneficial for fostering community and connection in a positive environment with perceived benefits extending beyond symptom management to participant reported improvements in function, daily life, and disease experience.

Telerehabilitation for Neurological Motor Impairment: A Systematic Review and Meta-Analysis on Quality of Life, Satisfaction, and Acceptance in Stroke, Multiple Sclerosis, and Parkinson's Disease

Telerehabilitation (TR) seems to be a viable and feasible solution to face the rehabilitative challenges posed by neurological impairments and to improve patients' quality of life (QoL). This review aims to synthesize and analyze the evidence on the impact of physiotherapy intervention through TR on QoL in patients with stroke, Parkinson's disease (PD), and multiple sclerosis (MS), together with an evaluation of their satisfaction and technology acceptance levels. Through a systematic search of the literature and a screening process, treatment effects were assessed with meta-analyses using the standardized mean difference, setting the confidence interval at 95%. We included 28 studies in the review, which were analyzed for methodological quality, whereas 16 studies were included in the meta-analyses. The results suggest a significant improvement in QoL in patients who underwent TR. We were unable to perform analyses for satisfaction and technology acceptance outcomes due to insufficient data. Overall, motor TR has a positive impact on the QoL of patients with neurological diseases, especially in stroke patients; although caution is needed in the interpretation of the results due to the high heterogeneity found. For PD and MS, TR seems to yield comparable results to in-person treatment.

Randomized controlled trial of the behavioral intervention for physical activity in multiple sclerosis project: Social cognitive theory variables as mediators

BACKGROUND

We recently reported in a phase-III, randomized controlled trial that a behavioral intervention based on social cognitive theory (SCT) and delivered through the Internet using e-learning approaches increased device-measured minutes/day of moderate-to-vigorous physical activity (MVPA) over a 6-month period among persons with multiple sclerosis (MS).

OBJECTIVE

This planned tertiary outcome paper examined SCT variables as mediators of the behavioral intervention effect on change in device-measured minutes/day of MVPA.

METHOD

Persons with MS (N = 318) were randomized into behavioral intervention (n = 159) or attention/social contact control (n = 159) conditions. The conditions were administered over a 6-month period via an Internet website and supported with behavioral coaching by persons who were uninvolved in screening, recruitment, random assignment, and outcome assessments. We collected MVPA and SCT data before and after the 6-month period. The data analysis involved linear mixed modeling on MVPA and SCT outcomes followed by latent change score modeling for examining SCT variables as mediators of the intervention effect on change in MVPA.

RESULTS

The linear mixed model indicated statistically significant group by time interactions on device-measured minutes/day of MVPA and scores from SCT measures of exercise self-efficacy, barriers self-efficacy, goal setting, and planning. The effect of the intervention on device-measured minutes/day of MVPA was mediated by the SCT variable of exercise self-efficacy based on the statistical significance of the Wald z-score for the indirect effect in the latent change score model.

CONCLUSIONS

This study provides evidence for exercise self-efficacy as a SCT mediator of the behavioral intervention effect on device-measured minutes/day of MVPA in persons with MS.

Study protocol for an online lifestyle modification education course for people living with multiple sclerosis: the multiple sclerosis online course (MSOC)

BACKGROUND

People living with multiple sclerosis (plwMS) seek access to information on evidence-based lifestyle-related risk factors associated with multiple sclerosis (MS). As the internet has made delivery of lifestyle information increasingly accessible and cost-effective, we designed the Multiple Sclerosis Online Course (MSOC) to deliver a multimodal lifestyle modification program for plwMS. Two MS online courses were developed: the intervention course based on lifestyle recommendations of the Overcoming Multiple Sclerosis (OMS) program and the standard-care course representing standard lifestyle recommendations from other MS websites. We examined for feasibility in a pilot randomised controlled trial (RCT), where satisfactory completion and accessibility were achieved across both study arms. From this success, a protocol for a larger RCT was developed to examine the effectiveness of MSOC in improving health-related quality of life (HRQoL) and other health outcomes in plwMS.

METHODS/DESIGN

This single-blinded RCT will recruit n = 1,054 plwMS. Participants in the intervention arm will receive access to a MSOC with seven modules providing evidence-based information on the OMS program. Participants in the control group will receive access to a MSOC of identical format, with seven modules providing general MS-related information and lifestyle recommendations sourced from popular MS websites, e.g. MS societies. Participants will complete questionnaires at baseline and at 6, 12, and 30 months after course completion. The primary endpoint is HRQoL, as measured by MSQOL-54 (both physical and mental health domains) at 12 months following course completion. Secondary outcomes are changes to depression, anxiety, fatigue, disability, and self-efficacy as measured by Hospital Anxiety and Depression Scale, Patient-Determined Disease Steps and University of Washington Self-Efficacy Scale, respectively, assessed at each timepoint. Further assessments will include quantitative post-course evaluation, adoption and maintenance of behaviour change from follow-up survey data, and qualitative analysis of participants' outcomes and reasons for course completion or non-completion.

DISCUSSION

This RCT aims to determine whether an online intervention course delivering evidence-based lifestyle modification recommendations based on the Overcoming Multiple Sclerosis program to plwMS is more effective at improving HRQoL, and other health outcomes post-intervention, compared with an online standard-care course.

Physiotherapist and participant perspectives from a randomized-controlled trial of physiotherapist-supported online vs. paper-based exercise programs for people with moderate to severe multiple sclerosis

PURPOSE

There is a gap in research on how best to support exercise in moderate to severe MS. The objective of this study is to share perspectives of people living with MS and physiotherapists on their experiences in a randomized clinical trial of online physiotherapy vs. an active comparator.

METHODS

Semi-structured exit interviews were conducted with volunteer participants from the online and comparator arms of the trial, and focus groups were held with study physiotherapists. Transcripts were analyzed using reflexive thematic analysis.

RESULTS

Perspectives from participants with MS yielded three themes: usability of their program, utility of their program, and motivation to participate. Visual and dexterity impairments limited the usability of the online program. Having an opportunity "to be pushed" was valued by participants in both trial arms. Motivation to exercise was variable, and participants desired periodic face-to-face contact with their physiotherapists. Perspectives from trial physiotherapists yielded similar and complementary findings concerning usability and utility.

CONCLUSIONS

Participants with MS and physiotherapists found the online physiotherapy platform useful for supporting exercise, yet they identified some limitations. As the appeal of online platforms has increased since the pandemic, it will be important to consider the needs of people with moderate to severe MS.

TRIAL REGISTRATION NUMBER

NCT03039400.IMPLICATIONS FOR REHABILITATIONPeople with moderate-to-severe MS and physiotherapists involved in a clinical trial found online physiotherapy useful for supporting exercise. Physiotherapists and participants using the online program desired improved platform accommodations for people living with MS with visual and dexterity impairments.Physiotherapists and people living with MS from both the online exercise program and comparator groups perceived a need for more face-to-face contact and opportunities to build therapeutic alliance.Perspectives from prescribing physiotherapists and people living with MS about supporting exercise online may have practice implications during and post-pandemic.

Primary results of a phase-III, randomized controlled trial of the Behavioral Intervention for increasing Physical Activity in Multiple Sclerosis project

BACKGROUND

We undertook a phase-III, randomized controlled trial (RCT) that examined the effectiveness of a behavioral intervention based on social cognitive theory (SCT) and delivered through the Internet using e-learning approaches for immediate and sustained increases in physical activity among persons with multiple sclerosis (MS).

METHOD

The study followed a parallel group RCT design. Persons with MS (N = 318) were randomized into either behavioral intervention (n = 159) or attention/social contact control (n = 159) conditions. The conditions were administered over a 6-month period by persons who were uninvolved in screening, recruitment, random assignment, and outcome assessment. There was a 6-month follow-up period without access of conditions. We collected outcome data every 6 months over the 12-month period. The primary outcome was device-measured minutes/day of moderate-to-vigorous physical activity (MVPA). The data analysis involved a modified intent-to-treat approach (i.e. those who received the allocated conditions) using a linear mixed model.

RESULTS

There was a significant group by time interaction on the primary outcome of device-measured minutes/day of MVPA (p < 0.005). MVPA was increased immediately after the 6-month period in the behavioral intervention compared with control, and this difference was sustained over the 6-month follow-up.

CONCLUSION

This study provides evidence for the effectiveness of a widely scalable approach for increasing MVPA in persons with MS.

The effectiveness of nontraditional or home-based programing on ADL performance of individuals living with multiple sclerosis: A systematic review

PURPOSE

To examine evidence-based nontraditional and home-based interventions and their efficacy for use in individuals with MS to improve performance in their daily activities.

MATERIALS AND METHODS

A search of five databases including PubMed, CINAHL, Cochrane Library, OT Seeker, and Ovid Medline produced 924 research articles. Thirty-two articles were selected for full-text review, of which 15 were included in this systematic review.

INCLUSION CRITERIA

Articles were level 2B or higher evidence, had a minimum of 19 participants with MS, addressed ADLs or body functions supporting ADL performance, and were published since 2010.

EXCLUSION CRITERIA

Articles not written in English and not identified as nontraditional or home-based programming.

RESULTS

The review uncovered strong evidence for the use of the nontraditional interventions of vestibular rehabilitation, self-management, yoga, musical production, and ELEVIDA to improve ADL performance in individuals with MS. Strong evidence supported the use of home-based programs that included cognitive behavioral therapy, cooling suits, manual dexterity, strengthening, vestibular rehabilitation, and physical activity.

CONCLUSIONS

High levels of evidence support the use of nontraditional or home-based interventions to improve ADL performance in clients with MS. Innovation and technology continue to expand the occupational therapist's toolbox of interventions.

Randomized controlled trial of the behavioral intervention for increasing physical activity in multiple sclerosis project: Secondary, patient-reported outcomes

BACKGROUND

We undertook a randomized controlled trial (RCT) that investigated the effectiveness of a theory-based, Internet-delivered, behavioral intervention focusing on physical activity promotion for immediate and sustained improvements in secondary, patient-reported outcomes (PROs) of function, symptoms, and quality of life (QOL) in multiple sclerosis (MS).

METHOD

Persons with MS (N = 318) were recruited from throughout the United States and randomized into behavioral intervention (n = 159) or attention/social contact control (n = 159) conditions. The conditions were administered over a 6-month period by persons who were uninvolved in screening, recruitment, random assignment, and outcome assessment. There was a 6-month follow-up period without intervention access/content. We collected PROs data every 6 months over the 12-month period. The PROs included validated measures of walking and cognitive function, symptoms of fatigue, depression, anxiety, pain, and sleep quality, and QOL. The data analysis involved a modified intent-to-treat approach using a linear mixed model in JMP Pro 16.0.

RESULTS

There was a significant group by time interaction on Fatigue Severity Scale scores (p < .01) and physical subscale scores of the Modified Fatigue Impact Scale (p < .05). Scores on both measures decreased immediately after the 6-month period in the behavioral intervention compared with no change in the control condition, and this differential pattern of change was sustained over the 6-month follow-up. There were no group by time interactions on the other PROs.

DISCUSSION

This study provides evidence for the effectiveness of a novel, widely scalable approach for physical activity promotion and fatigue management in persons with MS, yet this must be contextualized with the absence of improvements in the other PROs.

A multiple sclerosis lifestyle behavior online course: Qualitative analysis of participants' motivations, expectations and experiences

Background

Modification of lifestyle-related risk factors for multiple sclerosis (MS) has been associated with improved health outcomes when compared with standard medical management alone. Based on an existing lifestyle modification program offered as a residential workshop, the MS Online Course (MSOC) was developed to translate the workshop into an online intervention. We performed a pilot randomized controlled trial (RCT), to assess the feasibility concepts of accessibility, learnability and desirability through quantitative and qualitative analyzes. In the present study, we performed additional qualitative analyzes to explore participants' motivations, expectations, and experiences of the MSOC. This study aims to complement prior feasibility analyzes and inform recruitment strategies and course content redevelopment so that its effectiveness may be assessed by examining behavior change and health outcomes in a future larger RCT.

Methods

Participants were recruited via online advertisements and randomized to either: the standard care course, containing material sourced from public facing MS websites; or the intervention course, based on an evidence-based lifestyle modification program for people with MS. Course completers were invited to participate in semi-structured interviews. Within a qualitative paradigm, reflexive thematic analysis of interviews was undertaken.

Results

Of 31 eligible participants, 17 completed the MSOC and 14 agreed to be interviewed. Four themes were identified in this analysis: (1) "Wanting to help others" (helping through volunteering, contributing to knowledge base, spreading the word; (2) "Seeking knowledge" (confirmation of existing knowledge; obtaining new knowledge, relevant, credible information); (3) "Doing what I can to help myself" (understanding lifestyle modification, changing my lifestyle, remaining well); and (4) "Changing attitudes" (finding positivity, feeling more confident and in control).

Conclusions

Participants were motivated to help others through research, help themselves by improving knowledge and to find ways to better manage their MS. Expectations included obtaining credible, reliable information, to substantiate existing knowledge, and to further understand lifestyle modification. Participants' experiences included confirmation of and obtaining new knowledge, and early implementation of modified lifestyle behaviors. These insights surrounding participants' motivations, expectations and experiences will assist in recruitment strategies, course redevelopment and outcome measures for the future RCT to examine the effectiveness of the MSOC.

Systematic review of participant characteristics in theory-based behavior change interventions for physical activity in multiple sclerosis: are we missing those with the greatest potential for lifelong benefits?

PURPOSE

This study examined participant characteristics, particularly disease duration, in theory-based physical activity behavior change trials in multiple sclerosis (MS) and summarized theoretical frameworks and changes in physical activity outcomes.

MATERIALS AND METHODS

PubMed, CINAHL, Embase, and Scopus were searched to identify potential trials. One reviewer screened titles and abstracts, and two reviewers then independently screened full-text articles based on predetermined eligibility criteria. Data were extracted by one reviewer and checked by a second reviewer.

RESULTS

Among 33 trials reviewed, only one trial reported a mean disease duration of less than five years (i.e., 4.5 years) for the sample. The remaining trials included samples with a mean disease duration of 6.7 years or longer. The most common theories used were Social Cognitive Theory, Trans-theoretical Model, and Motivational Interviewing. The effects on physical activity were heterogeneous; device-measured outcomes increased in 41.4% of studies, self-reported outcomes improved in 72.4%. Adherence (≥80%) was reported in 34.5% of studies.

CONCLUSIONS

There is little focus on persons with MS in the early disease course in physical activity behavior change interventions. Future research should include comprehensive theoretical approaches for more homogeneous effects across outcome measures when targeting those in the early stage and all MS populations.IMPLICATIONS FOR REHABILITATIONTheory-based physical activity behavior change interventions have not included persons with multiple sclerosis (MS) in the early disease course (<5 years since diagnosis).Disease duration has not been a criterion used to include or exclude participants in the reviewed theory-based behavior change interventions for physical activity in people with MS.The theory-based behavior change interventions in this review positively affected short-term physical activity levels in people with MS.

Occupational Therapy Practice Guidelines for Adults With Multiple Sclerosis

IMPORTANCE

Occupational therapy practitioners play an important role in addressing the occupational performance and participation needs of adults with multiple sclerosis (MS) and their caregivers.

OBJECTIVE

This Practice Guideline aims to help occupational therapy practitioners, as well as the people who manage, reimburse, or set policy regarding occupational therapy services, understand occupational therapy's role in providing services to adults with MS and their caregivers. This guideline can also serve as a reference for health care professionals, health care managers, educators, regulators, third-party payers, managed care organizations, and researchers.

METHOD

We examined, synthesized, and integrated the results of four systematic reviews into clinical recommendations. Three systematic reviews specified occupational domains as outcomes of interest, and one focused on interventions for caregivers of people with MS.

RESULTS

Twenty-one articles from the systematic reviews with strong or moderate strength of evidence served as the basis for the clinical recommendations.

CONCLUSIONS AND RECOMMENDATIONS

Four interventions benefited participation in the domains of activities of daily living or sleep. Two interventions improved participation in the domain of instrumental activities of daily living. One intervention improved work participation. Two interventions benefited caregivers and the quality of the relationship between the caregiver and person with MS. Other potentially appropriate interventions or areas to address on the basis of existing or emerging evidence are discussed in the Limitations: Gaps in the Evidence and Conclusions sections. What This Article Adds: This Practice Guideline provides a summary and application of the current evidence supporting occupational therapy intervention for adults with MS. It includes case examples and decision-making algorithms to support occupational therapy practitioners in addressing client goals.

The influence of COVID-19 pandemic lockdown on the physical activity of people with multiple sclerosis. The role of online training

BACKGROUND

COVID-19 pandemic has affected people with multiple sclerosis (PwMS) on various levels. Pandemic lockdown influenced the access to typical measures of physical activity such as out-door training or gym exercises.

METHODS

We performed a survey assessing physical activity during pandemic lockdown among PwMS treated in our MS center. The questionnaire encompassed questions regarding physical activity before and during lockdown, including the employment of online technologies.

RESULTS

The survey was completed by 262 PwMS. Physical activity before lockdown was declared by 74.4% of PwMS, regular exercises were declared by 30.9% of participants. Among physically active PwMS 50.5% limited their physical activity during the COVID-19 lockdown. The decrease in physical activity was reported more frequently by PwMS with higher levels of disability, particularly declaring regular exercises before lockdown. In the opinion of 39,7% of PwMS online training could replace standard exercises, however only 19,9% of PwMS were actively looking for online training during the lockdown. The interest in online exercise was greatest in the group ≤30 years of age and EDSS ≤2. Synchronous exercises were the preferred online training, particularly among PwMS with EDSS≥4.

CONCLUSION

Our findings indicate a need for systematic educational and organizational measures, promoting physical activity among PwMS and acknowledging pandemic conditions.

Evaluating occupational performance coaching to support fatigue management for people with multiple sclerosis: A feasibility study

Objective

To determine the feasibility of adding coaching sessions to a website (MS INFoRM) that supports self-directed fatigue management for people with multiple sclerosis (PwMS).

Design

Double-blind, parallel-group feasibility study.

Participants and setting

Twenty-six PwMS, who experienced severe fatigue (fatigue severity scale > 5.4), were recruited from participants who were ineligible for the main trial testing on the MS INFoRM website.

Intervention

Six 45-to-60-min sessions of one-on-one coaching plus access to the MS INFoRm website compared to two check-in phone calls plus access to the MS INFoRm website. Both study arms took place over 3 months.

Main measures

Feasibility parameters included proportion eligible of those screened; proportion consented; missing data; retention and adherence rates. Acceptability was explored through qualitative interviews. Secondary outcomes (self-efficacy and fatigue impact) were measured at baseline and post-intervention.

Results

76 people were invited to participate in this add-on study. 40 were interested and screened: 32 were eligible, 26 consented, and were randomized (mean age: 48.5 yrs (SD: 8.7), mean disease duration: 11.5 yrs). Retention was 85% (22 out of 26). Coaching adherence was high (86% attended ⩾ 5 sessions). At 3 months, people in the intervention group showed more improvements in self-efficacy and fatigue impact compared to the comparison group, however, the difference was not statistically significant (p = 0.471 and p = 0.147, respectively). The intervention was well-received by the participants and there were no adverse events.

Conclusion

Combining one-on-one coaching sessions along with web-based interventions is feasible and appreciated by the participants, and worth exploring further in a larger trial.

The Feasibility of a Web-Based Educational Lifestyle Program for People With Multiple Sclerosis: A Randomized Controlled Trial

Background

Modifiable lifestyle factors are important to aid people with multiple sclerosis in the self-management of their disease. Current self-management programs are limited by their face-to-face mode of delivery but there is immense potential with the internet to deliver these programs effectively.

Objective

The aims of this study are to assess the feasibility of a digitalized educational lifestyle self-management program for people with MS.

Methods

In this randomized controlled trial, people with MS were randomly allocated to participate in a 6-week tailored web-based educational lifestyle program or 6-week generic standard-care educational course, and were blinded to their allocation. Participants were recruited through multiple sclerosis (MS) Societies in four countries: Australia, New Zealand, Canada, and the United States. The primary outcome was to assess acceptability of the program defined as percentage completion of all modules at 6-weeks post-course commencement. Secondary outcomes included evaluating participant responses to the follow-up survey across three domains: accessibility, learnability, and desirability.

Results

Thirty-five participants from Australia, Canada, New Zealand, and the US completed the baseline survey and were randomized. Four participants were deemed ineligible due to incomplete baseline data; therefore, nine out of 15 and eight out of 16 participants completed 100% of the course in the intervention and standard-care arm courses, respectively.

Conclusions

This study found that this web-based educational lifestyle program is a feasible means of delivering educational content to people with MS via the internet according to our a priori targets of >40% of participants in the intervention arm, and >25% in the control arm to completing 100% of the course. It is therefore appropriate to evaluate this intervention further in a large, randomized controlled trial.

Trial registration

This study was prospectively registered with the Australian New Zealand Clinical Trials Registry (ID: ACTRN12621000245897).

Interventions for Instrumental Activities of Daily Living Among Adults With Multiple Sclerosis: A Systematic Review

IMPORTANCE

Occupational therapy practitioners need updated information about interventions that may improve or maintain functional changes in instrumental activity of daily living (IADL) engagement caused by multiple sclerosis (MS).

OBJECTIVE

To conduct a narrative synthesis of updated evidence on interventions within the scope of occupational therapy to improve or maintain performance of and participation in IADLs among adults with MS.

DATA SOURCES

CINAHL, MEDLINE in PubMed, Cochrane, OTseeker, and PsycINFO. Study Selection and Data Collection: This systematic review followed the Cochrane Collaboration methodology and is reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines for conducting a systematic review. Inclusion criteria were Level 1 or 2 evidence, published in English, published from January 2011 to December 2018, intervention within the occupational therapy scope of practice, and at least one IADL outcome measure.

FINDINGS

Nineteen randomized controlled trials (including pilot and feasibility trials) and 1 preintervention-postintervention study met inclusion criteria. Results of this review show strong strength of evidence for coaching interventions in addressing physical activity (PA) routines and moderate support in addressing medication routines. Moderate strength of evidence was found with mixed results for interventions involving coaching plus prescribed PA in improving PA participation.

CONCLUSIONS AND RELEVANCE

This systematic review supports occupational therapy practitioners addressing PA and medication health management and maintenance IADLs through the use of coaching interventions when treating people with MS. Other IADLs were addressed by the articles in this review but require more evidence to make clinical recommendations. What This Article Adds: Occupational therapy practitioners' skills in promoting habits and routines paired with utilization of evidence-supported coaching interventions can support independence with health management and reduce the negative impact of MS on daily activity participation.

These articles present a summary of the topic and case studies that demonstrate how the evidence from these reviews can inform clinical decision making. This Evidence Connection article includes findings from a systematic review of interventions within the scope of occupational therapy practice that improve or maintain performance of or participation in instrumental activities of daily living for people living with multiple sclerosis.

Attrition Within Digital Health Interventions for People With Multiple Sclerosis: Systematic Review and Meta-analysis

Background

Digital health interventions have revolutionized multiple sclerosis (MS) care by supporting people with MS to better self-manage their disease. It is now understood that the technological elements that comprise this category of digital health interventions can influence participant engagement in self-management programs, and people with MS can experience significant barriers, influenced by these elements, to remaining engaged during a period of learning. It is essential to explore the influence of technological elements in mitigating attrition.

Objective

This study aimed to examine the study design and technological elements of documented digital health interventions targeted at people with MS—digital health interventions that were intended to support a program of engagement over a defined period—and to explore how these correlated with attrition among participants of randomized controlled trials (RCTs).

Methods

We conducted a systematic review and meta-analysis of RCTs (n=32) describing digital health self-management interventions for people with MS. We analyzed attrition in included studies, using a random-effects model and meta-regression to measure the association between potential moderators.

Results

There were no measured differences in attrition between the intervention and control arms; however, some of the heterogeneity observed was explained by the composite technological element score. The pooled attrition rates for the intervention and control arms were 14.7% and 15.6%, respectively.

Conclusions

This paper provides insight into the technological composition of digital health interventions designed for people with MS and describes the degree of attrition in both study arms. This paper will aid in the design of future studies in this area, particularly for digital health interventions of this type.

Improving Health of People With Multiple Sclerosis From a Multicenter Randomized Controlled Study in Parallel Groups: Preliminary Results on the Efficacy of a Mindfulness Intervention and Intention Implementation Associated With a Physical Activity Program

Objectives: The objective of this study is to investigate the efficacy of psychological Interventions – Mindfulness or Implementation Intention – associated with a Physical Activity program, delivered via internet, in reducing Multiple Sclerosis symptoms.

Method: Thirty-five adults were randomly assigned to one of the three groups: a Mindfulness-Based Intervention group (N = 12), Implementation Intention group (N = 11), and a Control Group (N = 12). All the groups received the same Physical Activity program. The Mindfulness condition group received daily training in the form of pre-recorded sessions while the Implementation group elaborated their specific plans once a week. Mobility, fatigue, and the impact of the disease on the patient’s life were measured. Two measurement times are carried out in pre-post intervention, at baseline and after eight weeks.

Results: Overall, after 8 weeks intervention, results show that there was a significant increase in Walking distance in the three groups. In addition, the within-group analysis showed a statistically significant improvement between pre and post intervention on the physical component of the Disease Impact scale in the Implementation Intention group (p = 0.023) with large effect size, in the Mindfulness-Based Intervention group (p = 0.008) with a medium effect size and in the control group (p = 0.028) with small effect size. In the Implementation Intention group, all physical, psychosocial and cognitive Fatigue Impact subscales scores decreased significantly (p = 0.022, p = 0.023, and p = 0.012, respectively) and the physical component was statistically and negatively correlated (r = −0.745; p = 0.008) when Implementation Intention group practice a mild to moderate physical activity. In the Mindfulness-Based Intervention group, the physical component (MFIS) showed a statistically significant improvement (p = 0.028) but no correlation with moderate-to-vigorous physical activity (MVPA); the control group outcomes did not reveal any significant change.

Conclusion: The results of this study are very encouraging and show the feasibility of Mindfulness interventions associated with physical activity to improve the health of people with MS. Further study should assess Mindfulness interventions tailored to MS condition and using both hedonic and eudemonic measures of happiness.

Feasibility of a theory-informed mobile app for changing physical activity in youth with multiple sclerosis

BACKGROUND

Youth with multiple sclerosis (MS) have high levels of disease activity, depression and fatigue, and lower moderate to vigorous physical activity (PA). PA participation is associated with lower disease activity, depression and fatigue as well as higher self-efficacy, goal setting and decreased barriers. These latter constructs may be targeted by an intervention program for behavior change, and such intervention must account for disease rarity, geographical proximity and time constraints which limit the feasibility, accessibility, and sustainability of implementing a PA intervention in youth with MS. We have developed a theory-informed mobile-app based PA promotion program to address these barriers, Active Teens with Multiple Sclerosis (ATOMIC) and herein report the feasibility of delivering this intervention in youth with MS.

OBJECTIVE

To determine the feasibility of delivering the ATOMIC program to youth with MS.

METHODS

Fifteen youth with MS (13F, 16.6 ± 1.2 years) followed at the Hospital for Sick Children were enrolled in the ATOMIC intervention. Participants underwent a standard clinical evaluation; an exercise test to determine cardiorespiratory fitness; 7-day PA monitoring with an accelerometer; and completed standardized depression, fatigue questionnaires at baseline and post-intervention. Social cognitive scales related to self-efficacy, self-management, goal setting, perceived barriers, outcome expectancy, and social support were completed at baseline, six and 12-weeks. The 12-week mobile app PA intervention was informed by Social Cognitive Theory (SCT) and included: individualized PA coaching, PA self-monitoring (Fitbit), goal setting, social support and MS specific educational modules. Feasibility was defined as (1) meeting the recruitment target of 15 participants within a one-year period; (2) completion of ≥80% of study related questionnaires and testing; (3) a drop-out rate of less than 20%, and (4) adherence to the ATOMIC intervention program components of ≥80% (Fitbit wear, PA coaching calls, modules).

RESULTS

From March 2018 to April 2019, 53% of youth approached agreed to participate (15/28). 13/15 participants completed the intervention. 36 of the possible 39 coaching calls (92%: 3 possible phone calls per participant); 89% wear adherence to Fitbit_Charge2 data (mean = 75 ± 16.6 days of 84 days); and 5/12 (42%) of modules were completed. An average 8.4% (SD= 40%, range = -74.0 to 176%) increase in Fitbit steps above the first week of the intervention were observed. PA level from accelerometry at 12-weeks, aerobic fitness, depression and fatigue were unchanged. SCT scales indicated an increase in social support from friends (0.67-points, T = 2.7, pholm=0.04), and a decrease in outcome expectancy (-2.7, T = 3.0, pholm=0.03). There were no differences in self-efficacy, self-management or perceived barriers post intervention.

CONCLUSIONS

Our results indicate that the ATOMIC program is feasible for delivery in youth with MS. Future work is needed to understand how to best implement each element of SCT through added features in the mobile-app, and to evaluate how the individual components of SCT mediate change in PA behaviours of youth with MS.

RCT of a Telehealth Group-Based Intervention to Increase Physical Activity in Multiple Sclerosis: eFIT

Objective

To conduct a pilot randomized controlled trial to determine whether participation in a group-based structured telehealth intervention increases physical activity in people with multiple sclerosis (MS).

Methods

In this parallel-arms trial, all study procedures were administered remotely. Adults diagnosed with MS (any subtype) were randomized to one of two 12-week (1 h/wk) active conditions: eFIT, online moderated structured groups; or eJournal, online independent journaling. For comparison, a treatment-as-usual (TAU; i.e., no eFIT/eJournal) group was enrolled. The primary outcome was feasibility (completion and adherence). The secondary efficacy outcomes included self-reported physical activity level (International Physical Activity Questionnaire, IPAQ).

Results

Participants were 37 adults with MS. The sample was diverse: 66.7% female; age range 23-64 years; 17.5% Hispanic, 12.5% Black; and progressive and relapsing-remitting disease subtypes. Regarding feasibility, 70.7% completed; average adherence was 74.9%. Physical activity in active groups increased by 34.2% (baseline IPAQ = 2,406.8 ± 1,959.7, follow-up = 3,229.4 ± 2,575.2) and decreased in the TAU group by 17.4% (baseline = 2,519.9 ± 1,500.1, follow-up = 2,081.2 ± 1,814.9); group × time interaction was not statistically significant [F(2,25) = 1.467, p = 0.250; partial η² = 0.105].

Conclusions

Telehealth represents an accessible, acceptable vehicle to deliver targeted behavioral treatments to a neurologic population. eFIT may be an effective intervention for increasing physical activity, a historically intractable treatment target, in individuals with MS. In addition, these results provide evidence for feasibility of conducting fully remote clinical trial research.

Classification of Evidence

This study provides Class II evidence that for people with MS, participation in a group-based structured telehealth intervention compared with TAU resulted in a (non-significant) increase in self-reported physical activity level. The percentage of participants who completed follow-up questionnaires did not differ between groups. The trial was registered at ClinicalTrials.gov (NCT03829267).

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.

Lifestyle, exercise and activity package for people living with progressive multiple sclerosis (LEAP-MS): protocol for a single-arm feasibility study

BACKGROUND

We have co-designed a tailored blended physiotherapy intervention for people with progressive multiple sclerosis (PwPMS) who often struggle to access support for physical activity. Underpinned by self-management principles, the Lifestyle, Exercise and Activity Package for people with Multiple Sclerosis (LEAP-MS) intervention incorporates face-to-face or online physiotherapy coaching sessions with an accompanying online physical activity platform. The LEAP-MS platform is a multi-user system enabling user and physiotherapist to co-create activity plans. The LEAP-MS platform consists of an information and activity suite, interactive components enabling selection of exercises into an activity programme, goal setting and activity logging. The platform also facilitates online remote support from a physiotherapist through an embedded online messaging function. We aim to evaluate the LEAP-MS platform in a feasibility trial.

METHODS

LEAP-MS will be evaluated within a single-arm feasibility study with embedded process evaluation. After registration and initial eligible screening, 21 participants will be required to complete baseline self-completion measures. This will be followed by an initial home-based or online coaching session with a physiotherapist (who has received tailored self-management and digital resource training) and access to the online intervention for an initial 3-month period. During this period, participants are given the option to request up to five further home-based or online physiotherapy coaching sessions. Follow-up questionnaires and semi-structured interviews will be administered 3 months after baseline with participants and intervention physiotherapists. The LEAP-MS platform will be available to participants for a further 3 months. Usage of the LEAP-MS platform will be tracked during the full 6-month period and final follow-up will be conducted 6 months after baseline.

DISCUSSION

Feasibility outcomes (recruitment, retention, intervention uptake and safety) will be reported. The process evaluation will be undertaken to identify possible mechanisms for any observed effects. The data will inform full-scale evaluations of this co-produced, blended physiotherapy intervention.

Long-term Effectiveness of mHealth Physical Activity Interventions: Systematic Review and Meta-analysis of Randomized Controlled Trials

BACKGROUND

Mobile health (mHealth) interventions can increase physical activity (PA); however, their long-term impact is not well understood.

OBJECTIVE

The primary aim of this study is to understand the immediate and long-term effects of mHealth interventions on PA. The secondary aim is to explore potential effect moderators.

METHODS

We performed this study according to the Cochrane and PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. We searched PubMed, the Cochrane Library, SCOPUS, and PsycINFO in July 2020. Eligible studies included randomized controlled trials of mHealth interventions targeting PA as a primary outcome in adults. Eligible outcome measures were walking, moderate-to-vigorous physical activity (MVPA), total physical activity (TPA), and energy expenditure. Where reported, we extracted data for 3 time points (ie, end of intervention, follow-up ≤6 months, and follow-up >6 months). To explore effect moderators, we performed subgroup analyses by population, intervention design, and control group type. Results were summarized using random effects meta-analysis. Risk of bias was assessed using the Cochrane Collaboration tool.

RESULTS

Of the 2828 identified studies, 117 were included. These studies reported on 21,118 participants with a mean age of 52.03 (SD 14.14) years, of whom 58.99% (n=12,459) were female. mHealth interventions significantly increased PA across all the 4 outcome measures at the end of intervention (walking standardized mean difference [SMD] 0.46, 95% CI 0.36-0.55; P<.001; MVPA SMD 0.28, 95% CI 0.21-0.35; P<.001; TPA SMD 0.34, 95% CI 0.20-0.47; P<.001; energy expenditure SMD 0.44, 95% CI 0.13-0.75; P=.01). Only 33 studies reported short-term follow-up measurements, and 8 studies reported long-term follow-up measurements in addition to end-of-intervention results. In the short term, effects were sustained for walking (SMD 0.26, 95% CI 0.09-0.42; P=.002), MVPA (SMD 0.20, 95% CI 0.05-0.35; P=.008), and TPA (SMD 0.53, 95% CI 0.13-0.93; P=.009). In the long term, effects were also sustained for walking (SMD 0.25, 95% CI 0.10-0.39; P=.001) and MVPA (SMD 0.19, 95% CI 0.11-0.27; P<.001). We found the study population to be an effect moderator, with higher effect scores in sick and at-risk populations. PA was increased both in scalable and nonscalable mHealth intervention designs and regardless of the control group type. The risk of bias was rated high in 80.3% (94/117) of the studies. Heterogeneity was significant, resulting in low to very low quality of evidence.

CONCLUSIONS

mHealth interventions can foster small to moderate increases in PA. The effects are maintained long term; however, the effect size decreases over time. The results encourage using mHealth interventions in at-risk and sick populations and support the use of scalable mHealth intervention designs to affordably reach large populations. However, given the low evidence quality, further methodologically rigorous studies are warranted to evaluate the long-term effects.

Lifestyle, Exercise and Activity Package for People living with Progressive Multiple Sclerosis (LEAP-MS): adaptions during the COVID-19 pandemic and remote delivery for improved efficiency

The LEAP-MS (Lifestyle, Exercise and Activity Package for People living with Progressive Multiple Sclerosis) study has developed an individualised supported self-management approach for physical activity for people with progressive multiple sclerosis (MS) and severe disability. The intervention has been evaluated in a single-arm feasibility study with embedded process evaluation. The feasibility study was due to open to recruitment during the COVID-19 2020-2021 pandemic, 1 month into the first UK-wide lockdown. We worked rapidly to implement adaptions to the trial procedures and intervention delivery that we believe are applicable to randomised controlled trials. Recruitment became predominantly via self-referral. Electronic consent was employed, with consent discussions occurring over the telephone. Registration, consent, eligibility assessment and data collection as well as the intervention (online physical activity tool) were via a secure, encrypted multi-user web-based platform for participants, physiotherapists and researchers accessible via various hardware. Physiotherapy consultations, as well as the process evaluation, were conducted remotely using video conferencing software or the telephone. A remote training package for physiotherapists and site initiations was also developed and electronic site files employed. Our adaptions are extremely topical given the COVID-19 situation, and whilst not what we had originally planned, have enabled successful delivery of the feasibility study and are relevant to conducting randomised controlled trials and meeting the needs of people with MS who are far more isolated than ever before.

Web-based physical activity intervention for people with progressive multiple sclerosis: application of consensus-based intervention development guidance

OBJECTIVES

People with progressive multiple sclerosis (PwPMS) report that they recognise the benefits of activity on their physical and psychological health but need support to achieve their physical activity goals. We aimed to systematically develop a theoretically informed intervention that would enable PwPMS to more readily engage in regular physical activity.

DESIGN

We used an intervention mapping approach to inform intervention development.

SETTING

We conducted semistructured interviews with PwPMS and their families/carers and physiotherapists recruited from secondary care settings.

PARTICIPANTS

Fourteen PwPMS with an Expanded Disability Status Scale score of between 6 and 8 and 7 of their families/carers and 13 physiotherapists and 1 physiotherapy technician participated.

RESULTS

Interview data suggested that the development of supportive coaching relationships with physiotherapists could promote the ability of PwPMS to achieve a desirable and achievable physical activity plan. These interview data informed the prototype 'Lifestyle Exercise and Activity Package for Multiple Sclerosis' (LEAP-MS) consisting of a secure multiuser web-based platform (with an education and activity suite, interactive components enabling selection of exercises, goal setting and activity logging), up to six flexible face-to-face or web-based physiotherapy coaching sessions and remote support via an embedded web-based messaging function that all together draw on specific theory-based methods to achieve physical activity behaviour change, namely active learning, reinforcement, modelling, feedback, facilitation, goal setting and guided practice. Implementation is within a multiuser platform accessible to participants, trained physiotherapists and researchers.

CONCLUSIONS

We have followed an inclusive, systematic and transparent process to develop the LEAP-MS intervention that enables detailed description of components, context and guiding principles to inform ongoing evaluation. Importantly, PwPMS expressed the need for autonomy in developing physical activity plans. This has been achieved through the embedding of self-management principles in the design and delivery of the LEAP-MS intervention.

Retention of Physical Gains in the Community Following Physical Training for Multiple Sclerosis: A Systematic Review and Implications

Multiple sclerosis (MS) is a progressive neurological illness whose typically young adult onset results in a nearly entire lifetime of worsening disability. But despite being an unrelenting neurodegenerative disease, numerous clinical trials over the past 40 years for MS have vigorously attempted to improve or at least stabilize declining physical function. Although the vast majority of the studies assessed training effects only within controlled laboratory or clinic settings, in recent years a growing interest has emerged to test whether newer therapies can instead benefit real-life activities in the community. Nonetheless, comparatively little attention has been paid to whether the training gains can be retained for meaningful periods. This review discusses the comparative success of various physical training methods to benefit within-community activities in MS, and whether the gains can be retained long afterward. This review will suggest future research directions toward establishing efficacious treatments that can allow persons with MS to reclaim their physical abilities and maximize functionality for meaningful periods.

Telehealth in Multiple Sclerosis Clinical Care and Research

Purpose of Review

The COVID-19 pandemic has provided us with a unique opportunity to experiment with telehealth and evaluate its benefits and limitations. This review discusses the impact of telehealth on multiple sclerosis (MS) care and research in adults and children.

Recent Findings

Telehealth visits for MS patients have been shown to reduce missed workdays and costs for patients. Brief telephone-based counseling may be associated with better adherence to disease-modifying therapy, although results of multiple home-based tele-rehabilitation for people with MS have been equivocal. Overall, patients and providers have reported high levels of satisfactions with telehealth. Several remote disability measures and numerous other technological tools have emerged for use in remote MS research and care. Major challenges of telehealth include limitations to performing a complete neurologic exam and disparities in access to telehealth amongst vulnerable populations with limited access to virtual platforms.

Summary

Following the rapid expansion of telehealth during the pandemic, it is highly likely that we will continue to embrace the benefits of this valuable tool. Future directions for improving telehealth should include more evidence-based research on the diagnostic accuracy in neuroimmunology and reducing disparities in the access to telehealth.

Behavior Change Techniques in Physical Activity Interventions for Multiple Sclerosis

OBJECTIVE

To identify and summarize the behavior change techniques (BCTs) included in behavior change interventions for promoting physical activity in persons with multiple sclerosis (MS).

DATA SOURCES

PubMed, PsycINFO, Cumulative Index to Nursing and Allied Health Complete, Scopus, and Embase were initially searched in November 2019, and data extraction began in June 2020.

STUDY SELECTION

The inclusion criteria for studies were: adults older than 18 years with diagnosed MS, English language, clinical trial designs (ie, pre-post or randomized controlled trials), group or individual interventions, and home or community-based settings wherein physical activity was defined as a primary or secondary outcome. Exclusion criteria for studies included protocol manuscripts pending results, case studies, studies focused on populations with multiple chronic diseases, and interventions targeting multiple behaviors. Two researchers completed screening for study selection, and a third researcher served as a referee. Of the initially identified 8681 studies, 54 studies met selection criteria.

DATA EXTRACTION

Data extraction was completed by 3 researchers. Each article was coded by 2 of the 3 researchers, and a fourth researcher resolved discrepancies. Data extracted from each paper included study title, authors, country, year, sample size, study design, intervention details, physical activity outcomes, and BCTs.

DATA SYNTHESIS

Thirty-eight unique behavior change interventions were identified, and 53 of the 93 possible BCTs were included across the studies. The mean number of BCTs per study was 15, and studies and effect sizes across studies ranged from 0.04-1.49.

CONCLUSIONS

This review provides a comprehensive overview of BCTs as the active ingredients in behavior change interventions targeting physical activity in MS. Results from this study provide a compendium for future intervention development for increasing physical activity and improving overall health in MS.

Electronic Health Interventions in the Case of Multiple Sclerosis: From Theory to Practice

(1) Background: eHealth interventions play a growing role in shaping the future healthcare system. The integration of eHealth interventions can enhance the efficiency and quality of patient management and optimize the course of treatment for chronically ill patients. In this integrative review, we discuss different types of interventions, standards and advantages of quality eHealth approaches especially for people with multiple sclerosis (pwMS). (2) Methods: The electronic databases PubMed, Cochrane and Web of Science were searched to identify potential articles for eHealth interventions in pwMS; based on 62 articles, we consider different ways of implementing health information technology with various designs. (3) Results: There already exist some eHealth interventions for single users with a single-use case, interventions with a social setting, as well as eHealth interventions that integrate various single and social interventions and even those that may be used additionally for complex use cases. A key determinant of consumer acceptance is a high-quality user-centric design for healthcare practitioners and pwMS. In pwMS, the different neurological disabilities should be considered, and particular attention must be paid to the course of the treatment and the safety processes of each treatment option. (4) Conclusion: Depending on the field of application and the respective users, interventions are designed for single, social, integrated or complex use. In order to be accepted by their target group, interventions must be beneficial and easy to use.

A qualitative exploration of the participants' experience of a web-based physiotherapy program for people with multiple sclerosis: Does it impact on the ability to increase and sustain engagement in physical activity?

Background: Web-based exercise and physical activity interventions are being developed as a potential way to help people with multiple sclerosis achieve and maintain increased physical activity levels. Seeking feedback from people who have used such interventions will help guide the development process.Methods: In-depth interviews were used to explore the experiences of participants who used a web-based physiotherapy intervention as part of a feasibility randomized controlled trial. Interviews were audio-recorded, transcribed verbatim and analyzed using thematic analysis.Results: Eleven people (age 28-68) were interviewed. Most perceived that their physical activity had increased, primarily due to completing twice-weekly web-based physiotherapy sessions. Three key themes were identified. 'It's all in one place' encompasses the value of having a convenient and portable program. 'Keeping an eye' captures people's thoughts regarding the supervision offered by the physiotherapist, through the website, and 'Hopes and expectations' reflects the importance of having opportunity to discuss what may be gained from using such a program.Conclusions: This intervention offered a convenient, flexible and portable physiotherapy program which most people perceived helped them achieve and sustain increased levels of physical activity. Talking with people about expectations is important, particularly if a person's condition is deteriorating.IMPLICATIONS FOR REHABILITATIONWhen discussing the potential benefits of exercise programs with people with multiple sclerosis it is important to have honest and open conversations about the expectations of what may be achieved. This is particularly important for people with progressive disease.Web-based interventions may be most valuable to people who are technology literate, seek flexibility regarding where and when to exercise, prefer to exercise independently and have the confidence and skills to self-manage.Trial registration: ClinicalTrials.gov identifier: NCT02508961.

Rates, patterns, and correlates of fitness tracker use among older adults with multiple sclerosis

BACKGROUND

Older adults with multiple sclerosis (MS) engage in alarmingly low levels of physical activity. Fitness trackers may be a promising approach for promoting and monitoring physical activity among older adults with MS.

OBJECTIVE/HYPOTHESIS

This study reports on the rates, patterns of fitness tracker use in adults with MS who are over 60 years of age. We hypothesized that older adults with MS who use fitness trackers "users" would report significantly more physical activity than those who don't "non-users."

METHODS

Participants across the United States completed an online survey that included self-reported demographic and clinical characteristics, fitness tracker use questionnaire, and Godin Leisure-Time Exercise Questionnaire (GLTEQ) for measuring total and health-promoting physical activity (GLTEQ-HCS).

RESULTS

Of the 440 participants who completed the full survey, 112 (28%) identified as fitness tracker users. The most common activity monitors were Fitbit®, Smartphone app, Apple® watch, and Garmin®. Fitness tracker users mostly reported having relapsing-remitting MS, less disability (i.e., lower Patient Determined Disability Steps), higher income, and higher rates of employment. There was a statistically significant difference in GLTEQ Total (t(438) = -3.8, p = .001) and GLTEQ-HCS (t(438) = -2.8, p = .006) scores between fitness tracker users and non-users. Self-reported step counts were strongly correlated with both GLTEQ Total (ρ = .50) and GLTEQ-HCS (ρ = 0.54) scores in fitness tracker users.

CONCLUSIONS

Further research is warranted investigating fitness tracker use and interests among older adults with MS and how technology may be applied as a behavioral tool to increase physical activity among this growing portion of the MS population.

Pedometers, the frustrating motivators: a qualitative investigation of users' experiences of the Yamax SW-200 among people with multiple sclerosis

Purpose: Self-monitoring may represent a mechanism to enhance physical activity among people with multiple sclerosis. To optimise activity monitoring as a behavioural tool to increase physical activity, user experience must be understood. This study evaluated user experience of the Yamax SW-200 Digi-walker pedometer in a group of people with MS.Methods: Semi-structured interviews were conducted with 15 adults who participated in a 12-week pedometer-supported behavioural change intervention, the iStep-MS trial. Interviews were audio-recorded and transcribed verbatim. Data were analysed using the Framework Method.Results: An overarching theme Pedometers, the frustrating motivators captures the complex and often contradictory experience of the pedometer. Sub-themes include: Increasing activity awareness, which describes the pedometer's utility in raising activity consciousness; Numeric motivation provides insight into dual motivating and demotivating experiences of using an objective feedback device; (Un) usability focuses on practical concerns encountered in the day-to-day use of the monitor.Conclusion: The Yamax SW-200 Digi-walker raised awareness and enhanced participant motivation to engage in physical activity. Accuracy and usability concerns highlighted warrant consideration in the selection of this pedometer within a population with multiple sclerosis.

Exercise and lifestyle physical activity recommendations for people with multiple sclerosis throughout the disease course

Objectives:

To provide clinicians who treat multiple sclerosis (MS) patients with evidence-based or expert opinion–based recommendations for promoting exercise and lifestyle physical activity across disability levels.

Methods:

The National MS Society (“Society”) convened clinical and research experts in the fields of MS, exercise, rehabilitation, and physical activity to (1) reach consensus on optimal exercise and lifestyle physical activity recommendations for individuals with MS at disability levels 0–9.0 on the Expanded Disability Status Scale (EDSS) and (2) identify and address barriers/facilitators for participation.

Recommendations:

Based on current evidence and expert opinion, the Society makes the following recommendations, endorsed by the Consortium of Multiple Sclerosis Centers:

Feasibility of "Sit Less, Move More": An intervention for reducing sedentary behavior Among African Americans with MS

BACKGROUND

Sedentary behavior is a major concern in multiple sclerosis, as it may accelerate disease progression and physical disability. This is especially concerning in African Americans, who present with greater neurological disability than Caucasians.

OBJECTIVE

We conducted a feasibility trial on an intervention targeting sedentary behavior in African Americans with multiple sclerosis.

METHODS

We examined the feasibility of the Sit Less, Move More program, a 12-week behavioral intervention that used text messaging along with theory-driven newsletters and behavioral coaching for managing sedentary behavior. We recruited ambulatory, inactive, African Americans with multiple sclerosis, and assessed feasibility on process, resource, management, and scientific outcomes.

RESULTS

Of the 64 people initially contacted, 45 were assessed for eligibility, 31 were sent the informed consent document, and 30 returned a signed document and were included in the study. Study costs were US$7242.38. Personnel time to complete the study was 130 h. There was a small effect on both device-measured (d = -0.19) and self-reported (d = -0.39) sedentary behavior.

CONCLUSIONS

The Sit Less, Move More intervention is safe and feasible for African Americans with multiple sclerosis, and yielded a small reduction in sedentary behavior. The intervention was low cost and well received. Our results suggest the Sit Less, Move More program should progress towards a Phase II trial to determine its efficacy.

'I can do this': a qualitative exploration of acceptability and experiences of a physical activity behaviour change intervention in people with multiple sclerosis in the UK

OBJECTIVES

The purpose of this study was to explore the experiences of people with multiple sclerosis (MS) who participated in iStep-MS, a feasibility randomised controlled trial of a behaviour change intervention that aimed to increase physical activity and reduce sedentary behaviour.

DESIGN

A qualitative approach was undertaken embedded in the feasibility randomised controlled trial. One-to-one semi-structured interviews were conducted and analysed using Framework analysis.

SETTING

Participants were recruited from a single MS therapy centre in the southeast of England, UK.

PARTICIPANTS

Sixty people with MS were randomly allocated in a 1:1 ratio to the intervention or usual care. Following a purposive sampling strategy, 15 participants from the intervention arm undertook 1:1 semi-structured interviews.

INTERVENTIONS

The iStep-MS intervention consisted of four therapist-led sessions over 12 weeks, supported by a handbook and pedometer.

RESULTS

Three themes were identified from the data. "I can do this": developing competence in physical activity highlights the enhanced physical activity confidence gained through goal setting and accomplishment. "I felt valued": the nurturing culture provides an overview of the supportive and non-judgemental environment created by the programme structure and therapeutic relationship. Finally, "What can I do?": empowered enactment describes the transition from the supported iStep-MS intervention to intrinsically motivated physical activity enactment.

CONCLUSIONS

Overall, this study supports the acceptability of the iStep-MS intervention and identified key areas that supported participants to be physically active.

Adherence to Physiotherapy-Guided Web-Based Exercise for Persons with Moderate-to-Severe Multiple Sclerosis: A Randomized Controlled Pilot Study

Background

Options to support adherence to physical activity in moderate-to-severe multiple sclerosis (MS) are needed. The primary aim was to evaluate adherence to a Web-based, individualized exercise program in moderate-to-severe MS. Secondary aims explored changes in 29-item Multiple Sclerosis Impact Scale, Hospital Anxiety and Depression Scale (HADS), grip strength, Timed 25-Foot Walk test, and Timed Up and Go (TUG) results.

Methods

Participants were randomized (2:1) to a physiotherapist-guided Web-based home exercise program or a physiotherapist-prescribed written home exercise program. The primary outcome was adherence (number of exercise sessions over 26 weeks). Secondary outcomes were described in terms of means and effect sizes.

Results

There were 48 participants: mean ± SD age, 54.3 ± 11.9 years; disease duration, 19.5 ± 11.0 years; and Patient-Determined Disease Steps scale score, 4.4 ± 1.6. There was no significant difference in mean ± SD adherence in the Web-based group (38.9 ± 28.1) versus the comparator group (34.6 ± 40.8; U = 198.5, P = .208, Hedges' g = 0.13). Nearly 50% of participants (23 of 48) exercised at least twice per week for at least 13 of the 26 weeks. Adherence was highest in the Web-based subgroup of wheelchair users. Medium effect sizes were found for the HADS anxiety subscale and in ambulatory participants for TUG. There were no adverse events.

Conclusions

There was no difference in exercise adherence between the Web-based and active comparator groups. There was no worsening of secondary outcomes or adverse events, supporting the safety of Web-based physiotherapy. More research is needed to determine whether wheelchair users might be most likely to benefit from Web-based physiotherapy.

Safety, feasibility, acceptability and effects of a behaviour-change intervention to change physical activity behaviour among people with multiple sclerosis: Results from the iStep-MS randomised controlled trial

Background:

There is limited information regarding the safety, feasibility and acceptability of behaviour-change interventions to increase physical activity (PA) and reduce sedentary behaviour among people with multiple sclerosis (MS). Prior to evaluating efficacy, it is important to identify problems with feasibility and acceptability, which may undermine effectiveness.

Objective:

To examine the safety, feasibility and acceptability of a behaviour-change intervention to increase PA and reduce sedentary behaviour among people with MS.

Methods:

Sixty people received a 3-month intervention or usual care. Fatigue, pain and adverse events (AEs) were assessed. Feasibility and acceptability were explored through focus groups with physiotherapists and interviews with participants. Fidelity to intervention content, delivery skills, programme receipt and programme task were assessed.

Results:

There was no difference in AE rate between groups ( p = 0.965). Fatigue and pain were not higher in the intervention group at 3 or 9 months. Therapists reported the intervention was feasible to deliver and fidelity was acceptable. Twenty-nine participants (97%) attended at least 75% of sessions. Participants found the intervention acceptable but suggested some amendments were required to intervention components.

Conclusions:

The intervention was safe, feasible and acceptable. Although modifications are required to intervention components, the intervention warrants further evaluation in a future trial.

Telemedicine in Neurological Disorders: Opportunities and Challenges

Introduction: Telemedicine represents an emerging model for the assessment and management of various neurological disorders. Methods: We sought to discuss opportunities and challenges for the integration of telemedicine in the management of common and uncommon neurological disorders by reviewing and appraising studies that evaluate telemedicine as a means to facilitate the access to care, deliver highly specialized visits, diagnostic consultations, rehabilitation, and remote monitoring of neurological disorders. Results: Opportunities for telemedicine in neurological disorders include the replacement of or complement to in-office evaluations, decreased time between follow-up visits, reduction in disparities in access to healthcare, and promotion of education and training through interactions between primary care physicians and tertiary referral centers. Critical challenges include the integration of the systems for data monitoring with an easy-to-use, secure, and cost-effective platform that is both widely adopted by patients and healthcare systems and embraced by international scientific societies. Conclusions: Multiple applications may spawn from a model based on digitalized healthcare services. Integrated efforts from multiple stakeholders will be required to develop an interoperable software platform capable of providing not only a holistic approach to care but also one that reduces disparities in the access to care.

Integrated telerehabilitation approach in multiple sclerosis: A systematic review and meta-analysis

INTRODUCTION

Multiple sclerosis (MS) is a chronic immune-mediated disease of the central nervous system and a major cause of disability in young adults. Recently, there has been a growing interest in the development of innovative ways to deliver rehabilitation care outside of a hospital setting. The aim was to conduct a systematic review and a meta-analysis of the efficacy of an integrated telerehabilitation approach (ITA) on motor, cognitive and participation outcomes delivered to people with MS (pwMS).

METHODS

We systematically searched for original manuscripts regarding ITA in pwMS. Efficacy on motor, cognitive and participation outcomes was measured as the standardized mean difference (Hedges' g) of pre and post training.

RESULTS

Nine studies encompassing 716 pwMS diagnosis were included. The overall effect of ITA was: large for motor outcomes (g = 1.05; p = 0.013); small for cognitive performance outcomes (g = 0.16; p = 0.237); and small for participation outcomes (g = 0.15; p = 0.259). Domain-specific results showed that the effect on motor disability was large (g = 1.18), while on gait and balance was medium (g = 0.32 and g = 0.48, respectively). Moreover, all effects on single cognitive domains were small. Finally, among the single participation outcomes considered (depression, fatigue, daily functioning, quality of life and self-efficacy) only depression showed a nearly medium effect (g = 0.30).

CONCLUSIONS

PwMS can benefit from ITA in the treatment of motor symptoms according to the current model of continuity of care. However, the low efficacy of ITA on cognition and participation domains suggests the necessity to develop intervention models that include a broader spectrum of needs and objectives.

Do Social Cognitive Theory constructs explain response heterogeneity with a physical activity behavioral intervention in multiple sclerosis?

Background

Behavioral interventions based on Social Cognitive Theory (SCT) are efficacious for increasing both objectively-measured and self-reported physical activity in people with multiple sclerosis (MS).

Purpose

This study involved a secondary analysis of data focused on SCT constructs as correlates of individual-level changes (i.e., response heterogeneity) following a behavioral intervention.

Method

Twenty-two persons with MS who completed a 6-month SCT-based behavioral intervention for increasing physical activity were included in analyses. The intervention consisted of two primary components, namely a dedicated Internet website and one-on-one video chats with a behavioral coach. Outcomes included objectively-measured moderate-vigorous physical activity (MVPA) using Actigraph model GT3X+ accelerometers and self-reported physical activity using the Godin Leisure-Time Exercise Questionnaire (GLTEQ) as well as SCT variables of exercise self-efficacy, barriers self-efficacy, outcome expectations, goal setting and planning and facilitators/impediments.

Results

There was individual variability in physical activity change following the intervention. For example, 4/22 participants demonstrated a reduction in MVPA, 1/22 participants had no change, 9/22 participants had less than 0.5 standard deviation (SD) increase in MVPA, and 8/22 participants had an increase in MVPA of more than 0.5 SD. Baseline SCT variables, particularly outcome expectations, goal setting, planning, and barriers self-efficacy, correlated with increased physical activity.

Conclusions

This study indicates that SCT variables correlate with the response heterogeneity associated with physical activity behavioral interventions, and this might inform the delivery of interventions consistent with Bandura's stepwise implementation model for optimizing the “fit” of an intervention based on SCT for maximizing treatment efficacy in MS.

Telerehabilitation in Multiple Sclerosis: Results of a Randomized Feasibility and Efficacy Pilot Study

A prospective, randomized, three-arm, evaluator blinded study to demonstrate the feasibility of a telerehabilitation (TR) program in individuals with ambulatory deficits secondary to Multiple Sclerosis (MS) and evaluate its efficacy when compared to conventional on-site physical therapy (PT) was completed. Thirty participants were evaluated at baseline and randomized to one of three groups with intervention lasting 8 weeks: Group 1 (control)- customized unsupervised home-based exercise program (HEP) 5 days a week; Group 2 (TR)- remote PT supervised via audio/visual real-time telecommunication twice weekly; Group 3 (PT)- in-person PT at the medical facility twice weekly. Outcomes included patient reported outcomes (PROs) obtained through questionnaires, and measurements of gait and balance performed with bedside tests and a computerized system. Functional gait assessment improved from baseline in all three groups. There were no significant differences between the TR and the conventional PT groups for a variety of outcome measures. TR is a feasible method to perform PT in persons with MS and has comparable efficacy to conventional in-person PT as measured by patient reported outcomes and objective outcomes of gait and balance.
