Physical activity and multiple sclerosis: a meta-analysis

The Neurologist as an Agent of Exercise Rehabilitation in Multiple Sclerosis

This review hypothesizes that the neurologist represents the linchpin of exercise behavior change within comprehensive multiple sclerosis (MS) care settings. This is based on a series of recent articles that developed actionable practice models for accomplishing such behavior change through the neurologist as the primary agent. This provides tangible, next steps for exercise promotion in MS.

Flipping the ICF: Exploring the Interplay of Theory and the Lived Experience to Reconsider Physical Activity in Community-Dwelling People With Multiple Sclerosis

People with multiple sclerosis (MS) report lower physical activity levels and are at a risk of becoming sedentary. As such, they are at an increased risk of developing secondary health conditions associated with inactivity. This is of major public health concern. Attempts to improve the physical activity levels in people with MS remain a challenge for health professionals. One key reason might be the lack of understanding about the meanings people with MS ascribe to exercise and physical activity. This paper draws on the key findings of a three-phased interconnected mixed methods sequential explanatory study to examine the meanings of exercise and physical activity from the perspectives of people with MS and health professionals. Phase 1 used a four-round Delphi questionnaire to scope and determine the consensus of priorities for exercise and physical activity and the reasons why people with MS (N = 101) engaged in these activities. Phase 2 used face-to-face semistructured interviews of people with MS (N = 16) to explore the meanings ascribed to exercise and physical activity. Phase 3 explored the perceptions of physiotherapists (N = 14) about exercise and physical activity using three focus groups. Using the International Classification of Functioning, Disability, and Health as a theoretical framework to underpin this study, the authors discuss the key factors, for example, emphasis on the contextual factors, that drive decision making around exercise and physical activity participation in people with MS and explore the clinical implications to health professionals.

Wearable technologies to measure clinical outcomes in multiple sclerosis: A scoping review

Wearable technology refers to any sensor worn on the person, making continuous and remote monitoring available to many people with chronic disease, including multiple sclerosis (MS). Daily monitoring seems an ideal solution either as an outcome measure or as an adjunct to support rater-based monitoring in both clinical and research settings. There has been an increase in solutions that are available, yet there is little consensus on the most appropriate solution to use in either MS research or clinical practice. We completed a scoping review (using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines) to summarise the wearable solutions available in MS, to identify those approaches that could potentially be utilised in clinical trials, by evaluating the following: scalability, cost, patient adaptability and accuracy. We identified 35 unique products that measure gait, cognition, upper limb function, activity, mood and fatigue, with most of these solutions being phone applications.

Associations between multiple sclerosis and incidence of heart diseases: Systematic review and meta-analysis of observational studies

BACKGROUND

Observational studies have described associations between multiple sclerosis (MS) and heart diseases, but the results were mixed.

METHODS

Medline, Embase, and Cochrane CENTRAL were searched up to 5 October 2020 according to a protocol (PROSPERO registration number CRD42020184493). We included longitudinal non-randomized studies of exposure comparing the incidence of acquired heart diseases between people with multiple sclerosis (pwMS) and people without multiple sclerosis. We used ROBINS-E and the GRADE approach to assess risk of bias and the certainty of evidence, respectively. Data were pooled using random-effect models.

RESULTS

Of 5,159 studies, nine studies met the inclusion criteria. MS was associated with an increased risk for myocardial infarction (HR 1.6, 95% CI 1.2 to 2.0, I2 86%, n = 1,209,079) and heart failure (HR 1.7, 95% CI 1.3 to 2.2, I2 49%, n = 489,814). The associations were more pronounced among women and younger people in subgroup analyses. We found no difference for ischemic heart disease (HR 1.0, 95% CI 0.8 to 1.4, I2 86%, n = 679,378) and bradycardia (HR 1.5, 95% CI 0.4 to 5.0, I2 50%, n = 187,810). The risk of atrial fibrillation was lower in pwMS (HR 0.7, 95% CI 0.6 to 0.8, I2 0%, n = 354,070), but the risk of bias was high, and the certainty of evidence was rated as very low. One study found more cases of infectious endocarditis among pwMS (HR 1.2, 95% CI 1.0 to 1.4, n = 83,712).

CONCLUSIONS

Myocardial infarction and heart failure should be considered in people with multiple sclerosis during follow-up examinations.

Effect of Exercise on Fatigue in Multiple Sclerosis Patients: A Network Meta-analysis

Few studies have directly compared the effects of different exercise therapies on reducing fatigue in patients with multiple sclerosis. Thus, we conducted a Frequentist network meta-analysis to analyze and compare the effectiveness of different types of exercise on reducing multiple sclerosis-related fatigue. Relevant randomized controlled trials were searched in PubMed, Web of Science and Cochrane Library databases from the date of their inception up to April 1, 2021. In total, 27 articles involving 1470 participants and 10 types of interventions met the inclusion criteria. The results indicated that aquatic exercise ranked as the most effective among these interventions, and aerobic exercise had small-to-moderate effect sizes. Most of the interventions were shown to be better than the control group, except for climbing. Climbing was the only intervention that ranked worse than the controls. All of these findings merit further investigation in future clinical trials.

Effect of COVID-19 home confinement on sleep monitorization and cardiac autonomic function in people with multiple sclerosis: A prospective cohort study✰,✰✰

BACKGROUND

Low sleep quality, cardiac autonomic dysfunction and poor quality of life are some of the most prevalent symptoms in people with Multiple Sclerosis (MS). In addition to the progression of the disease, these symptoms are aggravated by physical inactivity. Therefore, home confinement due to COVID-19 pandemic restrictions could further worsen these symptoms. This study aims to analyze the effect of home confinement on objective and subjective sleep quality, cardiac autonomic control based on heart rate variability (HRV), and health-related quality of life in people with MS.

METHODS

Actigraphic and subjective sleep quality (Karolinska Sleep Diary, KSD), HRV (Polar-H7), and quality of life (Multiple Sclerosis Quality of Life-54) were measured before and after 2 months of home confinement in 17 people with MS (7:10 men/women; age: 43.41±10.88 years; body mass index: 24.87±3.31 kg/m²; Expanded Disability Status Scale: 2.85±1.34 a.u.).

RESULTS

Actigraphic sleep quality (sleep efficiency: ES=1.27, p = 0.01, sleep time: ES=0.81, p = 0.01) and subjective sleep quality (sleep quality: ES=-0.34, p = 0.05), sleep comfort: ES=0.60; p = 0.03, ease of falling asleep: ES=0.70; p = 0.01, ease of waking up: ES=0.87, p<0.01, and having enough sleep: ES=0.87, p<0.01) significantly decreased after home confinement. No differences were observed in HRV or quality of life variables (p ≥ 0.13).

CONCLUSIONS

Home confinement has worsened the sleep quality, but not in cardiac autonomic control or quality of life, in people with MS. These data highlight the importance of implementing home physical training programs in this population when situations similar to home confinement occur, thus minimizing the negative effects of physical inactivity and their associated comorbidities.

PILOT STUDY OF ENHANCING CARDIORESPIRATORY EXERCISE RESPONSE IN PEOPLE WITH ADVANCED MULTIPLE SCLEROSIS WITH HYBRID FUNCTIONAL ELECTRICAL STIMULATION

OBJECTIVE

To investigate through a pilot study the acute cardiorespiratory responses during functional electrical stimulation (FES) cycling, arm cranking exercise (ACE) and a combination of ACE and FES cycling (Hybrid FES cycling) in people with advanced multiple sclerosis (MS) to provide preliminary guidance for effective aerobic exercise prescription.

DESIGN

Acute repeated measures.

SETTING

Laboratory setting.

PARTICIPANTS

Inclusion criteria was a diagnosis of MS, with Expanded Disability Status Scale (EDSS) 6.0 to 8.5. Included were 9 participants (7 female, age 54.7 ± 8.8 years, EDSS 7.0 ± 7.2).

INTERVENTION

Participants were assessed on three different exercise modalities (FES cycling, ACE, Hybrid FES cycling) at 40%, 60%, 80% and 100% of mode-specific peak workload.

MAIN OUTCOME MEASURES

Oxygen consumption (VO₂) and heart rate (HR) were measured at each workload.

RESULTS

Hybrid FES cycling evoked a significantly higher VO_2relative (mL∙kg^-1∙min^-1) and HR (bpm) at most workloads as compared with ACE or FES cycling. At the 100% workload, HR for Hybrid FES cycling was 125 (113-148) bpm and was significantly higher than ACE at 99 (95-119) bpm (p=0.008) and FES cycling at 94 (79-100) bpm (p=0.008). Similarly, at the 100% workload, VO_2relative for Hybrid FES cycling was 11.8 (7.6-17.6) mL∙kg^-1∙min^-1 and was significantly higher than ACE at 8.9 (5.3-12.5) mL∙kg^-1∙min^-1 (p=0.012) and FES cycling at 6.8 (4.1-9.2) mL∙kg^-1∙min^-1 (p=0.012).

CONCLUSIONS

This pilot study showed that Hybrid FES cycling can elicit a greater cardiorespiratory response compared to ACE or FES cycling in people with advanced MS. Thus, Hybrid FES cycling might provide a potent enough stimulus to induce clinically relevant changes in cardiorespiratory fitness. Training studies are warranted to document the magnitude and sustainability of aerobic capacity adaptations to Hybrid FES cycling and associated health outcomes in advanced MS.

"How Come You Sent Me the Canadian One?" Application and Uptake of the Canadian Physical Activity Guidelines for Adults With Multiple Sclerosis in the United States

The uptake and benefits of the Canadian Physical Activity Guidelines for Adults with Multiple Sclerosis (PAGs) have been validated, but there is limited understanding regarding the knowledge, needs, and preferences of people with multiple sclerosis (MS) for implementing the PAGs outside of clinical research. The authors conducted online, semistructured interviews with 40 persons with MS from across the United States seeking information on awareness of and potential approaches for increasing the uptake of the PAGs. They identified first impressions and potential approaches for increasing the uptake of the PAGs through inductive, semantic thematic analysis. Participants perceived the PAGs as a good introduction for structured exercise but desired more information on how to meet the PAGs. Participants further believed that modifying the PAGs for inclusivity and applying a multifaceted approach for dissemination and implementation may increase uptake of exercise behavior. Physical activity research in MS should include both analyzing the effects of exercise and the unique challenges faced by persons with MS in putting the PAGs into practice.

VO2peak Response Heterogeneity in Persons with Multiple Sclerosis: To HIIT or Not to HIIT?

Exercise is described to provoke enhancements of cardiorespiratory fitness in persons with Multiple Sclerosis (pwMS). However, a high inter-individual variability in training responses has been observed. This analysis investigates response heterogeneity in cardiorespiratory fitness following high intensity interval (HIIT) and moderate continuous training (MCT) and analyzes potential predictors of cardiorespiratory training effects in pwMS. 131 pwMS performed HIIT or MCT 3-5x/ week on a cycle ergometer for three weeks. Individual responses were classified. Finally, a multiple linear regression was conducted to examine potential associations between changes of absolute peak oxygen consumption (absolute ∆V̇O_2peak/kg)_, training modality and participant's characteristics. Results show a time and interaction effect for ∆V̇O_2peak/kg. Absolute changes of cardiorespiratory responses were larger and the non-response proportions smaller in HIIT vs. MCT. The model accounting for 8.6% of the variance of ∆V̇O_2peak/kg suggests that HIIT, younger age and lower baseline fitness predict a higher absolute ∆V̇O_2peak/kg following an exercise intervention. Thus, this work implements a novel approach that investigates potential determinants of cardiorespiratory response heterogeneity within a clinical setting and analyzes a remarkable bigger sample. Further predictors need to be identified to increase the knowledge about response heterogeneity, thereby supporting the development of individualized training recommendations for pwMS.

Personal, health and function, and career maintenance factors as determinants of quality of life among employed people with multiple sclerosis

BACKGROUND

Multiple sclerosis (MS) is an intrusive disease that significantly affects labor force participation.

OBJECTIVE

This study examined the extent to which factors at the personal, health and function, and environmental/career maintenance levels contribute to the predictability power for quality of life among employed people with MS.

METHOD

Participants consisted of 523 members of nine National Multiple Sclerosis Society chapters representing 21 states and Washington, DC. These individuals were employed at the time of the survey, and they were primarily middle age (average age of 48 years) and Caucasian (74%).

RESULTS

The final hierarchical multiple regression model explained 54 percent of the variability in participants' quality of life scores, although none of the hypothesized personal/demographic predictors were significant. Participants who perceived better overall health and lower levels of stress, who experienced less severe cognitive and mobility-related MS symptoms, and who expressed stronger job-person matches and higher levels of job satisfaction reported higher quality of life scores than did other participants.

CONCLUSIONS

The findings underscore the complexity involved in predicting perceived quality of life among employed people with MS. Implications of these findings for future research and clinical practice are discussed.

Self-efficacy training as an adjunct to exercise in a person with progressive multiple sclerosis: a case report

Background: Increasing self-efficacy to exercise and minimizing disease-related barriers has been shown to improve physical activity levels and quality of life (QOL) in persons with multiple sclerosis (MS). Currently, little research has examined exercise self-efficacy in persons with more advanced MS. Purpose: Explore the effects of a self-efficacy plus exercise intervention on physical activity endurance and level, QOL, and fatigue in an individual with advanced MS and low self-efficacy.Methods: The participant was a 60-year-old, severely disabled female with secondary progressive MS and an Expanded Disability Status Score (EDSS) of 8. The 8-week intervention consisted of weekly discussions and MS-related education; four one-on-one sessions with a MS "mentor;" daily journal to record sleep quality, fatigue level, and physical activity. Outcomes included a modified 5-meter walk test (5MWT), MS Impact Scale (MSIS-29), Exercise Self-Efficacy Scale (EX-ES), Modified Fatigue Impact Scale (MFIS), MS Self-Efficacy Scale (MS-SES), Patient Health Questionnaire-9 (PHQ-9), and daily physical activity monitoring. Outcomes were assessed at baseline (week 0), post-intervention (week 8), and 8 weeks post intervention (week 16). The participant continued her regular exercise routine independently throughout the study period.Results: There were notable improvements in EX-ES, MFIS, PHQ-9, MSIS-29 psychological subscale, sleep quality, and morning fatigue ratings post intervention, some of which were retained at follow up.Conclusion: The findings illustrate that an 8-week self-efficacy intervention increased exercise self-efficacy, QOL, and reduced perceived fatigue in a severely disabled individual with progressive MS. Future research should examine self-efficacy interventions in a larger sample size of persons with progressive MS.

Effects of normobaric hypoxic endurance training on fatigue in patients with multiple sclerosis: a randomized prospective pilot study

Background

Fatigue is one of the most frequent symptoms in patients with multiple sclerosis (MS), causing a major impact on quality-of-life. Non-pharmacological intervention strategies involve physical activity, which has been shown to reduce fatigue. Training under normobaric hypoxic conditions is thought to improve the response to endurance training and may, therefore, have an additional benefit over normoxic training conditions in MS patients.

Objective

To compare the effects of endurance training under hypoxic and normoxic conditions on fatigue, mobility and spasticity in patients with MS during inpatient rehabilitation.

Methods

Thirty-nine patients with MS were assigned within a randomized prospective longitudinal pilot study to (1) a routine clinical rehabilitation program, (2) a routine clinical rehabilitation program + normoxic endurance training and (3) a routine clinical rehabilitation program + hypoxic endurance training for 14 days. Fatigue (WEIMuS and MFIS), spasticity (MSSS-88) and walking endurance (6MinWT) were assessed at days 0, 7 and 14.

Results

Fatigue scores improved significantly in all groups, but these improvements were reached faster in the groups which additionally received endurance training (normoxic p = 0.004; hypoxic p = 0.002). Spasticity scores were significantly lower in endurance training groups at the end of the study compared to baseline (normoxic p = 0.048, hypoxic p = 0.012), while only the hypoxic group increased significantly in 6MinWT (p = 0.001).

Conclusions

Our findings demonstrate that endurance training provides substantial benefit to neurological rehabilitation programs. Endurance training under hypoxic conditions could positively influence walking endurance within a 2-week training intervention and warrants further investigations.

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

BACKGROUND

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

OBJECTIVE

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

METHODS

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

RESULTS

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

CONCLUSIONS

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

The SitLess With MS Program: Intervention Feasibility and Change in Sedentary Behavior

Objectives

This study reports on the feasibility of the SitLess with MS trial, an intervention targeting sedentary behavior in individuals with multiple sclerosis (MS).

Design

Single group, pre-post intervention design.

Setting

Community.

Participants

Participants (N=41) with mild to moderate disability from MS.

Intervention

The intervention was 15 weeks, with a 7-week follow-up, and included 2 stages: SitLess and MoveMore. During the SitLess stage, participants were encouraged to break up prolonged sitting bouts over a 7-week period, whereas the MoveMore stage promoted increased steps per day and interrupting sitting over a 7-week period. The intervention was delivered through weekly one-on-one coaching sessions via telerehabilitation and an accompanying newsletter based on social-cognitive theory. Activity was monitored throughout the program using a Fitbit.

Main Outcome Measures

Process (eg, recruitment) and resource and management (eg, personnel requirements) metrics were assessed, along with efficacy outcomes (eg, effect). Progression criteria were set a priori and were related to safety, fatigue, satisfaction, and attrition. Sedentary behavior, measured using the ActivPal, was reported pre- and postintervention, as well as 7 weeks postintervention. Effect sizes (pre to post, pre to 7 weeks post) were calculated for the sedentary behavior outcomes (eg, time sitting, transitions from sitting to standing, number of long sitting bouts). Experiences with the intervention were explored through an online survey.

Results

Forty-one participants enrolled, 39 of whom completed the intervention. All participants but 1 were satisfied with the experience. Pre-post intervention effect sizes for change in total sedentary time, number of transitions from sit to stand, and number of long (>30 min) sedentary bouts were 0.34, 0.02, and 0.39 respectively. All a priori progression criteria were met.

Conclusions

The SitLess with MS program, a novel intervention that emphasized and facilitated sitting less and moving more, was feasible and resulted in small changes in sedentary behavior in individuals with MS.

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.

ASPIRE trial: study protocol for a double-blind randomised controlled trial of aspirin for overheating during exercise in multiple sclerosis

INTRODUCTION

The many benefits of exercise for persons with multiple sclerosis (MS) are well established, yet patients often refrain from exercise due to overheating and exhaustion. The present randomised controlled trial tests aspirin (acetylsalicylic acid (ASA)) as a convenient method to prevent overheating and improve exercise performance in persons with MS. The effects of ASA are compared with those of acetaminophen (APAP) and placebo.

METHODS AND ANALYSIS

Participants are seen for a laboratory maximal exercise test on 3 separate days separated by at least 1 week. At each session, body temperature is measured before oral administration of a standard adult dose (650 mg) of ASA, APAP or placebo. One hour after drug administration, participants perform a maximal ramp test on a cycle ergometer. Primary outcomes are (a) time to exhaustion (that is, time spent cycling to peak exertion) and (b) body temperature change. Crossover analyses will include tests for effects of treatment, period, treatment-period interaction (carryover effect) and sequence.

ETHICS AND DISSEMINATION

Ethical approval was granted by the institutional review board at Columbia University Irving Medical Center (reference: AAAS2529). Results of the trial will be published in peer-reviewed scientific journals and presented at national and international conferences. Neurologists, physiatrists, primary care physicians and physiotherapists are important stakeholders and will be targeted during dissemination. Positive trial results have the potential to promote aspirin therapy, an inexpensive and readily available treatment, to reduce overheating and allow more persons with MS to benefit from exercise.

TRIAL REGISTRATION NUMBER

Physical Activity, Resilience, Sense of Coherence and Coping in People with Multiple Sclerosis in the Situation Derived from COVID-19

The confinement forced by COVID-19 can have repercussions on the health of people diagnosed with multiple sclerosis. The objective of this study is to analyze the relationships between physical activity, a sense of coherence, resilience and coping among people diagnosed with Multiple Sclerosis during the health emergency situation. To achieve this goal, this transversal descriptive study included 84 patients that belonged to multiple sclerosis associations during the period of confinement. Participants filled out the Physical Activity (IPAQ-SF), Sense of Coherence (SOC-13), Resilience Scale (ER-14) and coping (COPE-28) questionnaires. The results showed that the average age was 46.9 and that 67.9% had Relapsing Remittent Multiple Sclerosis diagnosed on average 13.9 years ago. They had a high degree (33.3%) and moderate degree (34.5%) of physical activity, high levels of resilience, while the level of a sense of coherence was average and the most commonly used strategies for coping were active confrontation and religion. Physical activity was not related to the rest of the studied variables, but there were correlations between the other variables. The people with multiple sclerosis who belong to patient associations have remained physically active during the obligatory confinement period and have elevated degrees of resilience and an average sense of coherence, as well as using suitable coping strategies, which is why the social-health resource of belonging to a patient association could be boosting these variables that are beneficial to their health.

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.

Change and onset-type differences in the prevalence of comorbidities in people with multiple sclerosis

BACKGROUND

Little is known about the change in prevalence of comorbidities during the disease course of people with multiple sclerosis (MS) and whether the prevalences vary by MS onset type.

OBJECTIVE

To calculate the change in prevalence of comorbidities between symptom onset and the time of study, to compare the prevalences of comorbidities with those in the Australian population at the time of study and to examine onset-type differences.

METHODS

Comorbidity data from 1518 participants of the Australian MS Longitudinal Study and Australian population comparator data (2014-2015 National Health Survey) were used. The change in prevalence between time points and prevalence ratios (PR) at the time of study (crude, age and sex adjusted, and stratified by onset type) was calculated.

RESULTS

Comorbidities were common, and those with the largest increases in prevalence between MS symptom onset and the time of study were depression (+ 26.9%), anxiety (+ 23.1%), hypertension (+ 21.9%), elevated cholesterol (+ 16.3%), osteoarthritis (+ 17.1%), eye diseases (+ 11.6%), osteoporosis (+ 10.9%) and cancer (+ 10.3%). Compared to the general population and after age and sex adjustment, participants had a significantly higher prevalence for 14/19 comorbidities at the time of study. The associations were strongest for anaemia, cancer (both PR > 4.00), anxiety, depression, migraine (all PR > 3.00), psoriasis and epilepsy (both PR > 2.00). No significant differences were seen by onset type.

CONCLUSION

Comorbidities are common at MS symptom onset and increase with MS duration. Having MS may thus contribute to accrual of comorbidities. This emphasises the importance of optimal screening for and management of comorbidities in early MS and throughout the disease course.

The effect of yoga practice on muscular strength improvement in patients with multiple sclerosis

Background/Aims

Multiple sclerosis is a common condition in the central nervous system where patients experience many issues, including muscle weakness. This study offers an investigation of continuous hatha yoga exercises on patients with multiple sclerosis.

Methods

A total of 22 participants with multiple sclerosis were selected, 11 were allocated to the intervention group, and 11 to the control group. In both groups, surface electromyography and dynamometer were performed at the beginning and the end of the study. The intervention group undertook 90-minute sessions of hatha yoga training three times a week for 6 months and the control group did not do any particular exercise during this period.

Results

Dynamometer results indicated that yoga significantly improved the muscle strength of the participants with multiple sclerosis (before the intervention: 40.00 Nm ± 14.66 Nm vs 56.82 Nm ± 20.28 Nm after the intervention, P=0.037). However, there was no significant difference in muscle strength changes between the intervention and control groups (16.82 Nm ± 23.26 Nm vs -2.86 Nm ± 23.36 Nm, P=0.171). Yoga significantly increased participants muscle strength according to the surface electromyography signals (before the intervention: 39.91 V ± 8.86 V vs 54.09 v ± 8.95 V after the intervention, P=0.007). The muscle strength of the control group participants with multiple sclerosis decreased after 6 months, however it was not statistically significant (41.55 Nm ± 9.3 Nm vs 34.55 Nm ± 8.36 Nm, P=0.073). The comparison of changes showed that the surface electromyography signals in the intervention group were significantly higher than those of the control group (P=0.001).

Conclusions:

Yoga exercises, in addition to common multiple sclerosis treatment methods, can be considered as a complementary therapy to improve the physical aspects of multiple sclerosis symptoms.

[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.

Evaluation of More Stamina, a Mobile App for Fatigue Management in Persons with Multiple Sclerosis: Protocol for a Feasibility, Acceptability, and Usability Study

BACKGROUND

Multiple sclerosis (MS) is one of the world's most common neurologic disorders leading to severe disability in young adults. MS-related fatigue directly impacts on the quality of life and activity levels of people with MS. Self-management strategies are used to support them in the care of their health. Mobile health (mHealth) solutions can offer tools to help symptom management. Following a user-centered design and evidence-based process, an mHealth solution called More Stamina was created to help persons with MS manage their fatigue.

OBJECTIVE

The overall study aims are to explore the feasibility, acceptability, and usability of More Stamina, a mobile app for fatigue self-management for persons with MS.

METHODS

A mixed-methods, multicenter study will be used to assess the feasibility, acceptability, and usability of More Stamina. The study will take place during the third and fourth quarters of 2020 (Q3-Q4 2020) in 3 locations: Argentina, Spain, and Switzerland. A longitudinal cohort study will take place, and think-aloud protocols, open-ended interviews, and short answer questionnaires will be used. Persons with MS will be recruited from the different locations. This study seeks to enroll at least 20 patients that meet the criteria from each site for the longitudinal cohort study (total n=60).

RESULTS

Ethical approval has been granted in Argentina and is pending in Spain and Switzerland. Outcomes will be published in peer-reviewed medical journals and presented at international conferences.

CONCLUSIONS

Findings from this study will be used to help understand the role that mHealth can play in fatigue management in MS.

Beyond center-based testing: Understanding and improving functioning with wearable technology in MS

Wearable sensors are designed to be worn on the body or embedded into portable devices (e.g. smartphones and smartwatches), allowing continuous patient-based monitoring, objective outcomes measuring, and feedback delivering on daily-life activities. Within the medicine domain, there has been a rapid increase in the development, testing, and use of wearable technologies especially in the context of neurological diseases. Although wearables represent promising tools also in multiple sclerosis (MS), the research on their application in MS is still ongoing, and further studies are required to assess their reliability and accuracy to monitor body functions and disability in people with MS (pwMS). Here, we provided a comprehensive overview of the opportunities, potential challenges, and limitations of the wearable technology use in MS. In particular, we classified previous findings within this field into macro-categories, considered crucial for disease management: assessment, monitoring, intervention, advice, and education. Given the increasing pivotal role played by wearables, current literature suggests that for pwMS, the time is right to shift from a center-based traditional therapeutic paradigm toward a personalized patient-based disease self-management. On this way, we present two ongoing initiatives aimed at implementing a continuous monitoring of pwMS and, consequently, providing timely and appropriate care interventions.

Associations between Activity Pacing, Fatigue, and Physical Activity in Adults with Multiple Sclerosis: A Cross Sectional Study

Fatigue is common in people with multiple sclerosis (MS). Activity pacing is a behavioral way to cope with fatigue and limited energy resources. However, little is known about how people with MS naturally pace activities to manage their fatigue and optimize daily activities. This study explored how activity pacing relates to fatigue and physical activity in people with MS. Participants were 80 individuals (60 females, 20 males) with a diagnosis of MS. The participants filled in questionnaires on their activity pacing, fatigue, physical activity, and health-related quality of life, 3-6 weeks before discharge from rehabilitation. The relationships between the variables were examined using hierarchical regression. After controlling for demographics, health-related quality of life, and perceived risk of overactivity, no associations were found between activity pacing and fatigue (β = 0.20; t = 1.43, p = 0.16) or between activity pacing and physical activity (β = -0.24; t = -1.61, p = 0.12). The lack of significant associations between activity pacing and fatigue or physical activity suggests that without interventions, there appears to be no clear strategy amongst people with MS to manage fatigue and improve physical activity. People with MS may benefit from interventions to manage fatigue and optimize engagement in physical activity.

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. Trial registration: Changing physical activity behaviour in people with MS: the iStep-MS trial; ISRCTN15343862; https://doi.org/10.1186/ISRCTN15343862Implications for rehabilitationUse of self-monitoring tools such as pedometers can enhance physical activity awareness.Objective, numeric step count feedback is an effective motivational tool for physical activity.Accuracy and usability concerns may limit the value of the Yamax SW-200 Digiwalker for people with MS.Identification of individualised, reliable, usable and acceptable tools is important to ensure engagement with self-monitoring.

Is Symptomatic Fatigue Associated With Physical Activity and Sedentary Behaviors Among Persons With Multiple Sclerosis?

Background. Fatigue is a debilitating symptom in multiple sclerosis (MS) that may be associated with reduced physical activity and increased sedentary behavior. Objective. This study examined the associations among fatigue and device-measured physical activity and sedentary behavior in people with MS. Methods. The participants (n = 252) completed the Patient Determined Disease Steps (PDDS) and Fatigue Severity Scale (FSS) and wore a waist-mounted accelerometer for 7 days. Participants were divided into 2 groups based on fatigue severity as measured by the FSS scale. We compared percentage of wear time spent in sedentary, light physical activity (LPA), and moderate to vigorous physical activity (MVPA) between the 2 groups. Results. Persons in the fatigued group (FSS score ≥ 4) spent a greater percentage of time in sedentary behavior (P = .004) and a lower percentage of time in LPA (P = .035). Persons in the fatigued group further spent a lower percentage of time in nontransformed MVPA (P < .001) and square-root-transformed MVPA (P < .001) than persons in the nonfatigued group. When controlling for PDDS scores and years of education, there were no longer significant differences between groups in sedentary behavior, LPA, or transformed MVPA values; the difference in nontransformed MVPA was still statistically significant but likely the result of nonnormally distributed data. Conclusion. The present study suggests that factors other than fatigue might be associated with physical activity and sedentary behavior in MS, and this group might benefit from focal behavioral interventions that take into account mobility status in persons with MS who have fatigue.

Medical Therapeutic Yoga for multiple sclerosis: examining self-efficacy for physical activity, motivation for physical activity, and quality of life outcomes

Purpose: Multiple Sclerosis (MS) is an incurable neurodegenerative disease that results in deficits in physical and cognitive function, and often fosters low levels of self-efficacy for physical activity, motivation for physical activity, and quality of life [1]. Drug therapies, physical therapy rehabilitation, and lifestyle modifications such as increased physical activity are standard protocol for symptom management, yet persons with MS tend to be physically inactive [2,3]. Additionally, single-modality interventions do not inherently address the challenges faced concurrently by individuals with MS [4,5].Methods: This project examined the effects of a 5-week holistic biopsychosocial Medical Therapeutic Yoga program on physical activity behavior outcomes in individuals diagnosed with MS. A mixed-methods approach was used to examine self-efficacy for physical activity, motivation for physical activity, and quality of life outcomes in 15 participants.Results: Quantitative measures demonstrated increased self-efficacy (t(14) = -2.23, p = 0.042), and emotional quality of life (t(14) = -2.66, p = 0.019). Responses to an open-ended written questionnaire and follow-up interviews indicated overall positive response to the program including increases in self-efficacy for physical activity, motivation for physical activity, and quality of life. These results may help future holistic programming for individuals with MS incorporate behavioral interventions with therapeutic rehabilitation to increase physical activity adherence.IMPLICATIONS FOR REHABILITATIONMultiple sclerosis is a neurological disease impacting physical and cognitive functioning that may be managed with a combination of drug therapies, rehabilitation, and physical activity.Individuals diagnosed with multiple sclerosis tend to be physically inactive and physical inactivity is a challenge for optimal disease management.Medical Therapeutic Yoga offers an interdisciplinary biopsychosocial framework to simultaneously address the behavioral challenges and physical impairments facing individuals diagnosed with multiple sclerosis.Health care providers should consider developing programs that use a biopsychosocial framework to aid in developing long-term adherence in health behaviors such as physical activity participation.

Effect of Exercise Interventions on Anxiety in People with Multiple Sclerosis: A Systematic Review and Meta-analysis

BACKGROUND

Evidence suggests that exercise can alleviate symptoms associated with multiple sclerosis (MS). However, it is unclear whether exercise alleviates symptoms of anxiety, present in one-third of people with MS. This systematic review and meta-analysis investigates whether exercise interventions are effective in reducing anxiety in people with MS.

METHODS

CINAHL, Embase, MEDLINE, PsycINFO, and the Cochrane Controlled Clinical Trials Register were searched to identify relevant randomized controlled trials (RCTs) published up to March 30, 2018. The primary outcome was postintervention difference in anxiety scores between intervention and control groups. Using a restricted maximum likelihood random-effects model, standardized mean differences were pooled and heterogeneity was estimated. Risk of bias was assessed using an a priori modified Cochrane Risk of Bias 2.0 tool.

RESULTS

Four RCTs with 133 participants were included. Exercise type included walking, aerobic activities, and cycling. Intervention duration ranged from 8 to 26 weeks. The pooled standardized mean difference in anxiety score was -0.16 (95% CI, -0.50 to 0.19), without heterogeneity. Two studies had high risk of bias, and two had some risk of bias.

CONCLUSIONS

Based on available RCT data, exercise does not seem to have an effect on anxiety in people with MS. These results should be interpreted with caution because studies had concerns of bias and small sample sizes, and anxiety was not the primary outcome measure. Future studies should exhibit sufficient reporting standards, alongside publishing protocols. There is opportunity to investigate the effect of exercise in people with MS experiencing clinically relevant levels of anxiety rather than in the general MS population.

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.

'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.

Using Body-Worn Sensors to Detect Changes in Balance and Mobility After Acute Aerobic Exercise in Adults with Multiple Sclerosis

Background

Current mobility and functional assessments do not capture the subtle changes in balance and gait that may predispose people with multiple sclerosis (MS) to falling. The purpose of this study was to use clinical and instrumented measures to examine the effects of an acute bout of aerobic exercise on balance and gait in individuals with MS.

Methods

Ten adults with MS performed 15 minutes of moderate-intensity recumbent cycling or 15 minutes of rest. Exercise and rest visit order was randomized and separated by 1 week. Balance and mobility were assessed before, immediately after, and 2 hours after each test condition.

Results

There were no significant differences across measurement periods for Timed 25-Foot Walk test times or Brief Balance Evaluation Systems Test scores. Significant improvements in mean sway radius and sway velocity when standing on foam and in percentage of stance stride time variability were found immediately after exercise compared with immediately after rest.

Conclusions

This study lends further evidence that individuals with MS can safely engage in single bouts of aerobic exercise without detrimental short-term effects on function and may actually receive some short-term benefit regarding standing postural sway and gait variability. Future research should examine the dose-dependent relationship of varying types, intensities, or timing of exercise necessary to elicit short-term functional benefit and long-term health outcomes.

Informing the training of health care professionals to implement behavior change strategies for physical activity promotion in neurorehabilitation: a systematic review

Initiatives to increase physical activity (PA) are most effective when combined with behavior change strategies (BCS). However, this is not routinely done and perhaps can be attributed to health care professionals' (HCP) lack of confidence and understanding of how to best apply BCS. This review aimed to identify and synthesize the existing literature describing methods used to train HCP to deliver BCS for PA promotion for individuals living with neurological conditions. This review followed the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. Eight databases were searched for articles describing how HCP were trained on BCS targeting PA and/or exercise for neurological pathology. Two researchers independently screened abstracts and used third-party consensus when needed. Studies must have described the planning/implementation of BCS targeting PA in adults with neurological disorders, with interventions delivered by a HCP. A data extraction table based on the study objective and the Cochrane Consumers and Communication Review Group's data extraction template was used. Risk of bias was assessed using the Quality Assessment Tools for Quantitative and Qualitative Studies. Included studies were also evaluated using the Workgroup for Intervention Development and Evaluation Research (WIDER) recommendations for reporting behavior change intervention content. Extraction and evaluation of risk of bias were completed independently by two researchers. Data were synthesized according to a who, what, when, and how approach. The search yielded 2,616 articles after duplicates removed, with 13 articles, representing eight unique interventions in individuals with spinal cord injury, stroke, multiple sclerosis, and Parkinson's disease included. Methodological quality ranged from strong to weak. Methods used to increase HCP knowledge and use of BCS were heterogeneous. Common training features included multiple resources, multiple sessions, expert input, and ongoing support, but a lack of evaluation of training effectiveness. The BCS were based on Social Cognitive Theory in seven interventions. Physiotherapists were the most common HCP trained. There was considerable variety in how HCP were trained to use BCS and a lack of evaluation of training effectiveness. Future work should include more description of the content and structure of HCP training and a direct measure of effectiveness. Researchers should consider implementation strategies during development and reporting of behavior change interventions. This review was not registered with PROSPERO.

The effects of aerobic exercise on sleep quality measures and sleep-related biomarkers in individuals with Multiple Sclerosis: A pilot randomised controlled trial

BACKGROUND

Sleep disturbances are highly prevalent in people with multiple sclerosis(MS), and are associated with pain, fatigue, depression, and reduced quality of life (QoL). Importantly, sleep has been considered a critical brain state for motor learning and memory consolidation. Therefore, interventions that target sleep managementin people with MS are needed.

OBJECTIVES

To explore the effects of a six weeks moderate-intensity aerobic exercise intervention on sleep characteristics and sleep-related biomarkers specifically serotonin, melatoninand cortisol in people with MS using a pilot randomized controlled trial.

METHODS

Participants were randomly allocated to either a moderate-intensity aerobic exercise program (MAE, n = 20) or a home exercise program (HEP, n = 20). Participants were assessed at baseline and follow-up. Subjective and objective measures were used to assess sleep quality. The Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) were used to subjectively assess sleep. While Actigraphy was used to objectivelyassess sleep. Blood samples were collected for measurement of cortisol, melatonin and serotonin from MS participants in both groups at 8:00 am±1 hour.

RESULTS

Seventeen participants in the MAE and 13 in the HEP group completed the study. Compared to the HEP group, people with MS who participated in a moderate-intensity aerobic exercise experienced significant improvements (P < 0.05) on the PSQI, ISI, and several objective sleep parameters measured using actigraphy. Only the serotonin levels increased significantly over the six-week period in the MAE group compared to the HEP group. The change score in serotonin (from baseline to follow up assessment) was significantly correlatedwith the change score in PSQI (r = -0.97, p < 001) and the change score in ISI (r = -0. 56, p = 0.015) only in the MAE group but not the HEP group.

CONCLUSIONS

Exercise may be a non-pharmacological, inexpensive, safe method to improve sleep quality in people with MS. The improvement in the serotonin level due to aerobic exercisemight explain one of the physiologic mechanisms driving these improvements.

Accessible exercise equipment and individuals with multiple sclerosis: Aerobic demands and preferences

BACKGROUND

Although exercise training has benefits for individuals with multiple sclerosis (MS), research regarding the type of exercise equipment that requires the greatest aerobic demand, and consumer-based preferences, is lacking.

OBJECTIVE

To determine the aerobic demands of various pieces of accessible exercise equipment and consumer-based preferences on several domains.

METHODS

Ten individuals with moderate-severity MS had their VO2 measured during 10 minutes of moderate-intensity arm ergometry (AE), body-weight support treadmill training (BWSTT), recumbent arm-leg exercise (NuStep), FES-arm exercise (RT300), FES-leg exercise (RT300) and FES arm-leg exercise (RT200). VO2peak test was also measured on the NuStep and the RT200. Equipment preferences were determined by questionnaire after moderate exercise sessions.

RESULTS

AE required a lower VO2 compared to the NuStep (p = 0.02), and FES-arm exercise required a lower VO2 compared to the NuStep (p = 0.01) and FES arm-leg exercise (p = 0.04). There was no difference in VO2peak when using the NuStep or FES arm-leg exercise. AE was perceived as safer than BWSTT, but otherwise there were no preferences for any equipment.

CONCLUSIONS

For individuals with moderate-severity MS, arm-only exercise requires less aerobic demands than combined arm-leg exercise at a moderate intensity. Perceived risks may be greater when exercise requires a transfer, upright positioning, or assistance.

Determinants of low bone mineral density in people with multiple sclerosis: Role of physical activity

BACKGROUND

People with multiple sclerosis (PwMS) have reduced bone mineral density (BMD), but the causes are unclear. Some factors that may cause reduced BMD in PwMS have been understudied, including physical activity, inflammation, cortisol, symptomatic fatigue, and depression. The aim of this study was to investigate factors that may uniquely contribute to reduced BMD in PwMS as compared to people without MS. We hypothesized that physical activity would be the primary determinant of low BMD in PwMS, with additional contributions from inflammation and sympathetic nervous system activation.

METHODS

We tested 23 PwMS (16 women; median EDSS: 2) and 22 control participants (16 women). BMD was measured from the femoral neck and lumbar spine with dual x-ray absorptiometry. Disability was measured with the Expanded Disability Status Scale, and functional capacity was measured with the Multiple Sclerosis Functional Composite. Questionnaires measured symptomatic fatigue and depression. A blood draw was used to measure calcium, phosphate, vitamin D, N-terminal telopeptide, osteopontin, and cytokine markers of inflammation. Physical activity was measured with accelerometry. Salivary cortisol and cardiac heart rate variability also were obtained. All outcome variables were compared between groups with independent samples t-tests. Variables that were different between groups and significantly correlated (Pearson product-moment) with femoral neck BMD, were included in a theoretical model to explain femoral neck BMD. The expected direction of relations in the theoretical model were developed based upon the results of previous research. A Bayesian path analysis was used to test the relations of predictive variables with femoral neck BMD and interrelations among predictive variables, as detailed in the theoretical model.

RESULTS

PwMS had lower BMD at the femoral neck than controls (p = =0.04; mean difference: -0.09; 95% CI: -0.2, -0.004; Cohen's d = =0.65), and there was a smaller, statistically non-significant difference in BMD at the lumbar spine (p = =0.07; mean difference: -0.08; 95% CI: -0.17, 0.007; Cohen's d = =0.59). PwMS also had lower functional capacity (p ≤ 0.001; Cohen's d = =1.50), greater fatigue (p<0.001; Cohen's d = =1.88), greater depression (p<0.001; d = =1.31), and decreased physical activity (p = =0.03; Cohen's d = =0.62). Using path analysis to test our theoretical model, we found that disability (standardized estimate= -0.17), physical activity (standardized estimate=0.39), symptomatic fatigue (standardized estimate= -0.36), depression (standardized estimate= -0.30), and inflammatory markers (standardized estimate=0.27) explained 51% of the variance in femoral neck BMD. Inflammatory markers were also predictive of disability (standardized estimate=0.44) and physical activity (standardized estimate= -0.40). Symptomatic fatigue and depression were correlated (r = =0.64).

CONCLUSION

Physical activity, symptomatic fatigue, depression, disability, and inflammation all contributed independently to decreased femoral neck BMD in PWMS. Bone metabolism in PwMS is complex. Efforts to increase physical activity and address symptomatic fatigue and depression may improve bone mineral density in PwMS. Future research should investigate the mechanisms through which symptomatic fatigue and depression contribute to reduced BMD in PwMS.

The Relationships between Physical Activity, Self-Efficacy, and Quality of Life in People with Multiple Sclerosis

Regular physical activity (PA) can enhance the physical and mental health of people with Multiple Sclerosis (MS) because of its impact on muscular strength, mobility, balance, walking, fatigue, pain and health-related quality of life (HRQoL). Previous studies have hypothesized that the relationship between PA and HRQoL is mediated by self-efficacy. The aim of this research is to evaluate whether self-efficacy in goal setting and self-efficacy in the management of symptoms, mediate the relationship between PA and HRQoL, in a similar way to exercise self-efficacy. A sample of 28 participants with MS (18 females) and different levels of physical activity have been recruited and completed the following measures: a) physical activity (GLTEQ); b) health-related quality of life (SF-12); c) self-efficacy in the management of Multiple Sclerosis (SEMS) and, d) exercise self-efficacy (EXSE). The statistical analysis highlighted that self-efficacy in goal setting mediated the relationship between PA and mental health better than exercise self-efficacy. Our findings suggest that self-efficacy in goal setting can contribute to the adoption and maintenance of regular physical activity for long-lasting times, supporting and increasing the mental quality of life of people suffering from MS.

Activity monitor use among persons with multiple sclerosis: Report on rate, pattern, and association with physical activity levels

BACKGROUND

Commercially available activity monitors are a promising approach for tracking and changing physical activity in multiple sclerosis.

OBJECTIVE

This study reports on the rate and pattern of activity monitor use in persons with multiple sclerosis, and compares self-reported physical activity levels between persons who do wear and those who do not wear activity monitors.

METHODS

Participants completed a cross-sectional survey that included a demographic and clinical characteristics scale, activity monitor use questionnaire, and Godin Leisure-Time Exercise Questionnaire (GLTEQ) for measuring total and health-promoting physical activity.

RESULTS

Of the 629 participants who completed the full survey, 249 (40%) reported using an activity monitor. The most common activity monitors were Fitbit, Apple watch, iPhone, and Garmin. There was a significant (p < 0.05), moderate difference (d = 0.5) in GLTEQ total scores between activity monitor users (36.6 ± 23.9) and non-users (25.0 ± 22.2), and in GLTEQ Health Contribution Score between activity monitor users (25.6 ± 22.3) and non-users (14.6 ± 18.9) (p < 0.05, d = 0.5). Self-reported steps from the activity monitor were significantly correlated with GLTEQ total score (ρ = 0.45; r = 0.36) and GLTEQ Health Contribution Score (ρ = 0.41; r = 0.35).

CONCLUSION

Activity monitor use is common among persons with multiple sclerosis, and activity monitor users report more total and health-promoting physical activity; this warrants further research investigating how devices may be used as a behavioral intervention tool.
