Modifiable Psychosocial Constructs Associated With Physical Activity Participation in People With Multiple Sclerosis: A Systematic Review and Meta-Analysis

Allied health professionals knowledge and clinical practice in telehealth exercise behavioural change for multiple sclerosis

BACKGROUND

The growing importance of telehealth in multiple sclerosis (MS) necessitates an understanding of current practices and training needs of health professionals. We aimed to evaluate the knowledge, preparedness, and training preferences of Australian allied health professionals (AHPs) in telehealth exercise therapy and exercise behavioural change for MS patients to inform the development of educational training.

METHODS

An online survey was completed by 58 Australian AHPs, including 34 physiotherapists, 14 exercise physiologists, and 10 occupational therapists, focusing on their current practices, preparedness, and training preferences in telehealth exercise and behavioural change for MS. The survey included multiple-choice, Likert scale, and free-text response questions. Data were analysed using binary and multinomial logistic regressions.

RESULTS

Not all AHPs were aware of MS exercise guidelines (67% awareness), with exercise physiologists showing the highest familiarity. There was a significant understanding of the difference between physical activity and exercise, though definitions often lacked clarity. Most AHPs (91%) employed behavioural change strategies in their practice, especially goal-setting (95%), identifying facilitators (67%), and reinforcing progress (66%). While most (72%) felt prepared in promoting exercise to MS clients, there were differences in confidence levels concerning the prescription, modification, and teaching of telehealth exercise programs, with occupational therapists have significant less confidence in those domains compared to other AHPs. Most AHPs expressed interest in additional training, with a preference for online workshops focusing on exercise prescription for MS, behaviour change, and telehealth delivery methods.

CONCLUSION

In our Australian AHP sample we identified that a quarter to a third of AHPs in MS care may not be confident or prepared to promote telehealth exercise and behavioural change to people with MS. Moreover, the findings highlight some disparity in knowledge and confidence levels amongst different AHPs concerning exercise therapy for MS, indicating the need for tailored multidisciplinary training programs. Such programs should address profession-specific educational gaps and training preferences, ensuring effective and safe telehealth exercise prescription in MS care.

Effects of multidisciplinary inpatient rehabilitation on everyday life physical activity and gait in patients with multiple sclerosis

BACKGROUND

Multiple sclerosis is a progressive neurological disease that affects the central nervous system, resulting in various symptoms. Among these, impaired mobility and fatigue stand out as the most prevalent. The progressive worsening of symptoms adversely alters quality of life, social interactions and participation in activities of daily living. The main objective of this study is to bring new insights into the impact of a multidisciplinary inpatient rehabilitation on supervised walking tests, physical activity (PA) behavior and everyday gait patterns.

METHODS

A total of 52 patients, diagnosed with multiple sclerosis, were evaluated before and after 3 weeks of inpatient rehabilitation. Each measurement period consisted of clinical assessments and 7 days home monitoring using foot-mounted sensors. In addition, we considered two subgroups based on the Expanded Disability Status Scale (EDSS) scores: 'mild' (EDSS < 5) and 'severe' (EDSS ≥ 5) disability levels.

RESULTS

Significant improvements in fatigue, quality of life and perceived mobility were reported. In addition, walking capacity, as assessed by the 10-m walking test, two-minute walk test and timed-up-and-go test, improved significantly after rehabilitation. Regarding the home assessment, mildly disabled patients significantly increased their locomotion per day and complexity of daily PA pattern after rehabilitation, while severely disabled patients did not significantly change. There were distinct and significant differences in gait metrics (i.e., gait speed, stride length, cadence) between mildly and severely disabled patients, but the statistical models did not show a significant overall rehabilitation effect on these gait metrics.

CONCLUSION

Inpatient rehabilitation showed beneficial effects on self-reported mobility, self-rated health questionnaires, and walking capacity in both mildly and severely disabled patients. However, these improvements do not necessarily translate to home performance in severely disabled patients, or only marginally in mildly disabled patients. Motivational and behavioral factors should also be considered and incorporated into treatment strategies.

Relationship between physical activity and coping with stress in people with multiple sclerosis: A moderated mediation model with self-efficacy and disability level as variables

Purpose

An increasing number of studies support the beneficial relationship between physical activity and stress coping in people with multiple sclerosis (MS). However, there has been limited understanding of the variables that may influence the nature of this relationship. Therefore, based on the social-cognitive framework and previous research, we aimed to examine the association between the habitual physical activity of people with MS and their coping effectiveness. Furthermore, we sought to determine the extent to which self-efficacy acts as a mediator in this relationship, considering the level of disability as a moderator variable.

Methods

In this cross-sectional study, a total of 351 people with MS participated. The participants were asked to complete several assessment tools, including the Mini-COPE Inventory for Measurement-Coping with Stress, the Generalized Self-Efficacy Scale, and the Godin Leisure-Time Exercise Questionnaire. Additionally, a neurologist assessed the severity of the disease using the Expanded Disability Status Scale. Information on the demographic and clinical characteristics of the participants was collected via a self-report survey. Two moderated mediation analyses were conducted as part of the study.

Results

The study findings indicated a positive correlation between engagement in physical activity and self-efficacy among participants with high and medium disability levels. This, in turn, demonstrated a positive association with effective stress-coping strategies and a negative association with ineffective coping methods. In particular, a significant relationship was observed between involvement in physical activity and self-efficacy in participants with high disability, while it was not statistically significant in participants with low disability.

Conclusion

Physical activity was associated with improved psychosocial functioning in people with high levels of disability caused by MS. This association may be attributed to factors such as increased self-efficacy and improved stress coping. However, the relationship between physical activity and psychosocial functioning was less evident in people with low disability caused by MS.

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.

Psychosocial Aspects of Rehabilitation in Neurodegenerative Diseases and Fields of Approach

Psychosocial health is a concept included in definition of health by World Health Organization and corresponds to state of emotional and social well-being. In the context of neurological disorder, psychosocial health refers to social reintegration and psychological adjustment. Studies reporting that neurological diseases are associated with negative psychosocial health outcomes such as a decrease in the quality of life, a decrease in ability to establish and maintain social relationships, and an increase in high levels of depression, stress and anxiety have increased in recent years. Therefore, it is important to consider programs and interventions that can improve the psychosocial health of people with neurodegenerative diseases. Currently, it is not clear which psychosocial approaches can produce definitively positive results. The aim of this study is to examine how being an individual with Multiple Sclerosis and Parkinson's, which are the most common neurodegenerative diseases in the clinic, affects psychosocial health in the rehabilitation process and the existing evidence-based psychosocial approaches. For this purpose, a descriptive review was prepared by scanning English and Turkish articles with keywords on psychotherapeutic, psychosocial and mindfulness-based interventions and stress management, published in the determined databases in the last 10 years. Studies have shown that psychosocial approaches such as interventions for acquisition of social integration and adaptive coping strategies, cognitive and social behavioral therapy methods, concentration and movement-based mind-body exercises are effective in rehabilitation of neurodegenerative diseases. These approaches were reported to have benefits in reducing anxiety, depression and fatigue, improving sleep quality and quality of life, relationships, employment, level of participation, motivation and self-efficacy in exercise and physical activity, improving physical functions, facilitating difficult and personal experiences and adaptation to new life in rehabilitation processes and more evidence-based studies are needed.

Yoga and Multiple Sclerosis: Maintaining engagement in physical activity

BACKGROUND

Physical activity is encouraged for people with Multiple Sclerosis. Yoga is a popular form of physical activity and is chosen by some people with Multiple Sclerosis. However, little is known about the impact of yoga for this population, alongside what influences ongoing engagement.

AIM

The aim of this study is to qualitatively explore the impact of online home-based yoga on people with Multiple Sclerosis and to explore factors that influence engagement.

METHODS

A qualitative study using semi-structured interviews and focus groups with people with Multiple Sclerosis and a yoga teacher. Thematic analysis was used to analyse the data. Ethical Approval was gained from Northumbria University.

FINDINGS

Three overarching themes emerged from the analysis. 'Yoga as engagement in physical activity' captured the reasoning for participating in yoga and how this method of physical activity was an alternative to physical activity done prior to diagnosis. Frustration was apparent within this theme that some individuals were unable to engage in the range of physical activity that they wished to. 'Yoga is a personalised approach' demonstrated the flexibility and inclusivity of yoga, for individuals with varying symptoms to be able to engage with. Finally, 'yoga impacts individuals both physically and psychologically' captured the focus on the psychological impact of yoga, improving wellbeing and control.

CONCLUSIONS

Yoga gives people with Multiple Sclerosis the feeling of control over their symptoms and a means to engage with meaningful physical activity. Prior involvement in physical activity influenced engagement in yoga and wanting to push themselves. There was reluctance among this group to engage with aerobic activity, which warrants future investigation and support from health and exercise professionals.

Three weeks of rehabilitation improves walking capacity but not daily physical activity in patients with multiple sclerosis with moderate to severe walking disability

Background

Patients with multiple sclerosis have low levels of physical activity. This is of concern because low activity levels are related to cardiovascular disease, poor walking ability, and reduced quality of life. The aim of this study was to evaluate the impact of rehabilitation on daily physical activity and walking capacity in patients with multiple sclerosis who have moderate to severe walking disability.

Methods

This exploratory, observational study of 24 patients with multiple sclerosis examined daily physical activity, walking capacity and fatigue before and after 3 weeks of inpatient rehabilitation. Inpatient rehabilitation included physiotherapy (30–60 min, 5 times/week), strength and endurance training (30–45 min, 3–5 times/week), occupational therapy (30 min, 2–3 times/week), and neuropsychological training (30 min, 2 times/week). There were no specific interventions to target daily levels of physical activity.

Results

Daily physical activity did not change after rehabilitation (physical activity: effect size = –0.23, 95% confidence interval (95% CI) 0.02‒0.62). There were significant improvements in walking capacity (Two-Minute Walk Test: effect size = 0.74, 95% CI 0.31‒1.16, +17 m, 20.2%) and mobility (Timed Up and Go Test: effect size = 0.65, 95% CI 0.22‒1.07, ‒2.1 s, 14.9%). Motor and cognitive fatigue (Fatigue Scale for Motor: effect size = 0.56, 95% CI 0.14‒0.99 and Cognitive Functions: effect size = 0.44, 95% CI 0.01‒0.86) improved significantly after rehabilitation.

Conclusion

Three weeks of rehabilitation improved walking capacity, but not daily physical activity, in patients with multiple sclerosis with moderate to severe walking disability. To increase physical activity, it may be necessary to add specific behavioural interventions to the rehabilitation programme. The intervention plan should include strategies to overcome personal and environmental barriers.

The Relevance of Competences for a Healthy, Physically Active Lifestyle in Persons with Multiple Sclerosis: a Path Analytical Approach

To promote health and counteract the decline associated with the disease, persons with multiple sclerosis (pwMS) are advised to lead healthy, physically active lifestyles. The physical activity-related health competence (PAHCO) model posits that individuals must meet three integrated, person-related requirements for the adoption of such a lifestyle: movement competence, control competence, and self-regulation competence. To gain insights into the needs and challenges of pwMS, the goal of the present study was to empirically examine the roles of these competences within this target group. A total of 475 pwMS underwent a multidimensional, online-based assessment of PAHCO. These participants self-reported their amount of physical activity (PA), health status, disease-related, and sociodemographic information. We used a series of path analyses to investigate the relevance of the three competence areas for each individual's PA level and subjective health. Stepwise multivariate analyses revealed that self-regulation competence was significantly associated with overall PA volume. In contrast, movement competence did not contribute to this prediction. Control competence was also not related to PA level. However, in accordance with the PAHCO model, this factor exerted an independent, qualitative effect on participant health. In summary, self-regulation competence appears to play a crucial role with regard to PA volume. Specifically, control competence appears to be key for the qualitative aspect of PA promotion, characterizing the individual's application of an appropriate stimulus for the achievement of health. Integrating the promotion of self-regulation and control competences into rehabilitation practices can help to foster healthy, physically active lifestyles in pwMS.Supplemental data for this article is available online at https://doi.org/10.1080/08964289.2021.1935437 .

Validity and reliability of the Persian version of the exercise self-efficacy scale in people with multiple sclerosis

BACKGROUND

Exercise self-efficacy has been identified as one of the primary determinants of physical activity in people with multiple sclerosis (MS). Therefore, assessment of exercise self-efficacy is important to be measured with valid and reliable scale to provide tailored interventions.

MATERIALS AND METHODS

The English version of the exercise self-efficacy scale was translated into Persian using a forward-backward translation approach. Factorial validity was conducted using the expletory factor analysis (EFA) and the confirmatory factor analysis (CFA). In addition, construct validity was performed using convergent and known-group validity. Reliability was evaluated by internal consistency and test-retest reliability. Participants were recruited from two hospitals (MS clinics).

RESULTS

Expletory factor analysis identified a single factor structure which explained 64.7% variance in exercise self-efficacy scale (EXSE). CFA supported a single factor structure with a good model fit. Average variance extracted = 0.60 and composite reliability = 0.93 values confirmed the convergent validity. The known-group validity was verified with significant differences between subgroups. The Cronbach's alpha coefficient = 0.93 and intraclass correlation coefficient = 0.85 supported reliability of EXSE scale.

CONCLUSIONS

Our findings provided sufficient evidence of validity and reliability for EXSE scale in people with MS. This measure can utilize by researchers and health-care providers in studies and clinical practice as a robust measure to assess exercise self-efficacy and to develop interventions in people with MS.

Behavior Change Interventions for Health Promotion in Physical Therapist Research and Practice: An Integrative Approach

There is an increasing focus on health promotion in physical therapist research and practice. A clinical model (Health-Focused Physical Therapy Model) was developed for identifying major steps in the delivery of health promotion focusing on adoption of healthy lifestyle behaviors. One of the primary steps within this model is the design and delivery of behavior change interventions. Such interventions involve coordinated sets of activities that target change in a specific pattern of unhealthy behavior (eg, physical inactivity, smoking). This Perspective contends that the science and practice of behavior change interventions can be significantly advanced in the field of physical therapy (implementation science) through the integration of behavior change frameworks and techniques within the context of an experimental medicine approach for health behavior change. This perspective presents the integration of the Theoretical Domains Framework, the Behavior Change Wheel, including the Capability Opportunity Motivation-Behavior core system, and the Behavior Change Technique Taxonomy as a comprehensive approach for designing and delivering behavior change interventions in physical therapy. An experimental medicine approach is described, outlining a 4-step process in the design, delivery, and evaluation of behavior change interventions that can be applied to health promotion in physical therapist research and practice. The proposed integrative approach can advance public health and health promotion through healthy lifestyle behavior change in the field of physical therapy.

Experiences of people with multiple sclerosis participating in a social cognitive behavior change physical activity intervention

BACKGROUND

Understanding the experiences of people with MS taking part in physical activity interventions is critical to inform future interventions.

AIM

The aim was to gain insight into the experiences of people with MS taking part in a behavior change group physical activity intervention with a novel social cognitive theory component.

METHODS

A qualitative semi-structured interview format was utilized. Questions focussed on expectations, views and beliefs at being involved in the study, beliefs on physical activity, and subjective evaluation of the trial content and delivery. Seventeen people were interviewed and data were analyzed using thematic analysis.

RESULTS

Three themes were generated: psychological and social factors, intervention processes, and MS identity. The acceptance of MS as an identity acted as an initial barrier to exercise, with a more positive, exercise-enabling identity post-intervention. Psychological factors such as self-efficacy and anxiety, as well as social factors such as social support, were found to play an important role in how participants experienced the program. Similarly, intervention processes included support for group-based activities and structure of exercise classes, and were also inter-linked to the other themes.

CONCLUSION

It appears that group-based exercise interventions are acceptable and feasible for people with MS. The qualitative findings support previously reported quantitative findings that the Step it Up intervention is effective at promoting physical activity and improving psychological outcomes.

Correlates of Objectively Measured Physical Activity Among People With Multiple Sclerosis: A Cross-Sectional Study

Background: Identifying correlates of physical activity (PA) for people with multiple sclerosis (MS) is essential to design effective PA interventions.

Methods: Participants completed a battery of questionnaires and wore an ActiGraph accelerometer. Light physical activity (LPA) and moderate-to-vigorous physical activity (MVPA) (min/day) were calculated. Associations were examined using multiple linear regression adjusted for demographic and clinical confounders.

Results: Fifty-eight adults with MS participated (mean ± SD age: 56.8 ± 9.2 yr; 67% women). MS type was associated with time in LPA. Participants with secondary progressive MS (B = −54.0, 95% CI −84.7 to −23.3) and primary progressive MS (B = −42.9, 95% CI −77.5 to −8.3) spent less time in LPA than those with relapsing remitting MS. Walking capacity, assessed using the 12-item MS walking scale (MSWS-12), was associated with time in MVPA (B = −0.36, 95% CI −0.72 to −0.01).

Conclusion: This work identifies walking capacity and type of MS as correlates of PA, which may indicate development of interventions to promote PA.

Maximising Abilities, Negotiating and Generating Exercise options (MANAGE) in people with multiple sclerosis: A feasibility randomised controlled trial

OBJECTIVE

To investigate the feasibility and preliminary efficacy of a group self-management exercise and education program in people with multiple sclerosis.

DESIGN

Feasibility randomised controlled trial.

SETTING

Outpatient rehabilitation facility.

SUBJECTS

Twenty-three adults (age 48.6 (11.7) years) recruited from a Multiple Sclerosis Clinic register.

INTERVENTIONS

The intervention group undertook a 12-week group program incorporating behaviour change education, exercise and community integration. This was compared with a waitlist control group.

MAIN MEASURES

Feasibility was measured by recruitment, adherence and safety. Efficacy outcomes included measures of physical function (6-metre and 6-min walk, Functional Reach) and self-report questionnaires (fatigue, quality of life, exercise benefits and barriers) at baseline, 6, 12 and 24 weeks.

RESULTS

Of 74 individuals identified through the register, 48 (65%) were contacted and deemed eligible, and 23 (48%) agreed to participate. There was high adherence for attendance at education (57 of 72, 79%) and exercise (135 of 174, 78%) sessions. No adverse safety events occurred within the intervention sessions. Missed attendances at assessment sessions was high (5 to 8 participants missed at each time point) predominately due to health issues. The intervention group demonstrated positive changes in walking endurance, Functional Reach and fatigue, whereas the control had some reductions in walking speed and more perceived exercise barriers.

CONCLUSIONS

The MANAGE program appears feasible and safe for people with mild-to-moderate multiple sclerosis, with high adherence to exercise and education sessions. Future trials should consider strategies such as flexible scheduling or alternative methods of data collection to improve follow-up assessment attendance.

Self-regulatory behaviour change techniques in interventions to promote healthy eating, physical activity, or weight loss: a meta-review

Poor quality diet, physical inactivity, and obesity are prevalent, covariant risk factors for chronic disease, suggesting that behaviour change techniques (BCTs) that effectively change one risk factor might also improve the others. To examine that question, registered meta-review CRD42019128444 synthesised evidence from 30 meta-analyses published between 2007 and 2017 aggregating data from 409,185 participants to evaluate whether inclusion of 14 self-regulatory BCTs in health promotion interventions was associated with greater improvements in outcomes. Study populations and review quality varied, with minimal overlap among summarised studies. AMSTAR-2 ratings averaged 37.31% (SD = 16.21%; range 8.33-75%). All BCTs were examined in at least one meta-analysis; goal setting and self-monitoring were evaluated in 18 and 20 reviews, respectively. No BCT was consistently related to improved outcomes. Although results might indicate that BCTs fail to benefit diet and activity self-regulation, we suggest that a Type 3 error occurred, whereby the meta-analytic research design implemented to analyse effects of multi-component intervention trials designed for a different purpose was mismatched to the question of how BCTs affect health outcomes. An understanding of independent and interactive effects of individual BCTs on different health outcomes and populations is needed urgently to ground a cumulative science of behaviour change.

Participant experiences of eight weeks of supervised or home-based Pilates among people with multiple sclerosis: a qualitative analysis

PURPOSE

An exploratory qualitative study investigating participants' experiences of a feasibility study of supervised and home-based Pilates.

METHODS

All 10 females who participated in an eight-week supervised (n = 4) or home-based Pilates (n = 6) program were invited and agreed to be interviewed. Data were collected via semi-structured interviews and researcher observations of participant experiences. Data were analysed using codebook thematic analysis framework.

RESULTS

Two domain summaries emerged: (1) the suitability of home-based Pilates in particular for this population. Participants indicated that supervised and home-based Pilates was a safe, intensity-appropriate, and implementable exercise method to improve mental health outcomes among persons with multiple sclerosis (PwMS), and (2) the benefits experienced by PwMS while participating in Pilates. Home-based Pilates reduced both exercise participation and accessibility barriers commonly experienced by PwMS. Furthermore, PwMS reported improvements in mental health outcomes following Pilates, in both exercise environments.

CONCLUSIONS

PwMS reported experiencing improved mood following regular Pilates training and indicated that home-based in particular reduced barriers regularly experienced by this population. Results support Pilates as a feasible exercise modality providing potential mood improvements among PwMS. Future appropriately powered home-based randomised controlled trials to further explore the effects of Pilates training on mental health among PwMS with minimal-to-mild mobility disability are warranted.Implications for RehabilitationParticipants in this study described the mental health benefits experienced from engaging in Pilates, a non-traditional exercise modality.Home-based Pilates overcame participatory and accessibility barriers to exercise among people with multiple sclerosis (MS).Participants valued that Pilates was low intensity and did not exacerbate fatigue.Home-based Pilates is a feasible exercise method for people with MS with minimal-to-mild mobility disability.

Intervention Mediators in a Randomized Controlled Trial to Increase Physical Activity and Fatigue Self-management Behaviors Among Adults With Multiple Sclerosis

BACKGROUND

People with multiple sclerosis (MS) often experience fatigue, which is aggravated by inactivity. Identifying mediators of changes in physical activity (PA) and fatigue self-management (FSM) behaviors could optimize future interventions that reduce the impact of MS fatigue.

PURPOSE TO

examine the effects of telephone-delivered interventions on Social Cognitive Theory constructs and test whether these constructs mediated secondary outcomes of PA and FSM behaviors.

METHODS

Participants with MS (n = 208; Mean age = 52.1; Female = 84.6%) were randomized into contact-control intervention (CC), PA-only intervention, and PA+FSM intervention. Step count (Actigraphy) and FSM behaviors as well as self-efficacy, outcome expectations, and goal setting for PA and FSM were measured at baseline, post-test (12 weeks), and follow-up (24 weeks). Path analyses using bias-corrected bootstrapped 95% confidence intervals (CI) determined whether constructs at post-test mediated behaviors at follow-up when adjusting for baseline measures.

RESULTS

Path analysis indicated that PA-only (β = 0.50, p < .001) and PA+FSM interventions (β = 0.42, p < .010) had an effect on goal setting for PA, and that PA + FSM intervention had an effect on self-efficacy for FSM (β = 0.48, p = .011) and outcome expectations for FSM (β = 0.42, p = .029). Goal setting for PA at post-test mediated the effects of PA-only (β = 159.45, CI = 5.399, 371.996) and PA + FSM interventions (β = 133.17, CI = 3.104, 355.349) on step count at follow-up. Outcome expectations for FSM at post-test mediated the effects of PA + FSM intervention on FSM behaviors at follow-up (β = 0.02, CI = 0.001, 0.058).

CONCLUSIONS

Goal setting for PA and outcome expectations for FSM may be important constructs to target in telephone-delivered interventions designed to reduce the impact of MS fatigue.

The Role of Perceived Energy and Self-Beliefs for Physical Activity and Sports Activity of Patients With Multiple Sclerosis and Chronic Stroke

Physical activity counteracts some of the negative consequences associated with chronic neurological diseases. Here, we describe the levels of physical activity (PA) and sports activity (Sport) in patients with multiple sclerosis (pMS, n = 59) and chronic stroke (pStroke, n = 67) and test compliance with the recommendation for health-promoting physical activity of the World-Health Organization (WHO). Secondly, we tested for differences between the groups of patients, and thirdly, we examined relationships between PA and Sport with psychological indicators of perceived energy (fatigue and vitality) and self-beliefs (self-efficacy and self-control). Psychological constructs were assessed with validated measures from different disciplines in Psychology. A statistical aim was to describe interpretations gained by (non-) parametric Bayesian and Null-Hypothesis-Significance Testing statistics (NHST) on the example of the conducted tests for differences and relationships. Descriptive analyses revealed that pMS and pStroke complied with recommendations of the WHO, but with large variance indicating that patient groups are not homogenous. Tests for differences showed that the PA difference between pMS and pStroke can be attributed to the higher proportion of women in the pMS sample as they engage more in household chores (important part of PA). Tests for relationships showed that for pStroke, vitality, self-control, and self-efficacy were positively related to the level of sports activity. Furthermore, pStroke who were sport active had lower fatigue and higher self-control and self-efficacy scores than sport inactive people. Although they address slightly different questions, the Bayesian and the NHST approach led to similar general conclusions.

Changing Behaviour towards Aerobic and Strength Exercise (BASE): Design of a randomised, phase I study determining the safety, feasibility and consumer-evaluation of a remotely-delivered exercise programme in persons with multiple sclerosis

BACKGROUND

Multiple sclerosis is a chronic progressive neurological disease. Evidence attests to the benefits of exercise, guidelines for exercise in multiple sclerosis are available. Remote-delivery of exercise adherence programmes based on the exercise guidelines require urgent testing.

AIMS

The design, and outcomes of Behaviour towards Aerobic and Strength Exercise in MS (BASE-MS), a remotely-delivered exercise training study based principles of behaviour change, will further evaluate the remote-delivery of the current exercise guidelines.

METHODS

BASE is a 4-month clinically relevant randomised controlled trial to explore the delivery of a remotely supervised, guidelines-based exercise programme for persons with multiple sclerosis, underpinned by principles of health behaviour change. Initially, 72 persons with mild to moderate multiple sclerosis will be randomised in a 1:1:1 allocation to receive the BASE programme, or act as controls continuing usual care. On programme completion, exercise participants will be further randomised to an optimised adherence treatment or usual adherence. Our online survey assesses the primary outcome of exercise participation, and secondary outcomes of symptoms, and correlates of behaviour change at baseline, month four, month five and month eleven. Online surveys will capture coach and participant feedback to identify the contexts, mechanisms and outcomes of BASE implementation.

CONCLUSIONS

The research and clinical landscape for MS management must remain in-step with public health and health communication. BASE tests the remote-delivery of the current exercise guidelines for exercise in persons with MS. Safety, feasibility and evaluative outcomes will provide rich data for future remote-delivery of exercise in neurological conditions.

Introduction of the Watzmann Severity Scale: A sensorimotor approach to estimate the course of inpatient rehabilitation in multiple sclerosis

Multiple sclerosis is an autoimmune disease with a plethora of potentially arising impairments and a coarse standard clinical estimation of severity, the expanded disability status scale (EDSS). In this study, we introduced the Watzmann Severity Scale (WSS), a sensorimotor function based statistical model of the EDSS of 113 patients. Using the WSS, we examined the rehabilitation course of 87 patients. The WSS revealed to be a reliable estimate of the EDSS with an R²_adjusted of 0.81, although lower EDSS grades were systematically overestimated. Further, patients slightly improved during their inpatient stay of in average 17d by 0.21 on the WSS, with changes in gait performance being the driving factor (|β|-weight of 0.84). We were not able to reliably predict changes in the WSS and found no association with the duration of hospitalization. We conclude and advise that rehabilitation should start earlier, if lower EDSS grades were not overestimated, to emphasize gait less in rehabilitation, and to change from a perspective of impairment and disability to performance in order to maximize patient rehabilitation.

Motivations Toward Exercise Participation: Active Persons With Multiple Sclerosis Have Greater Self-directed and Self-capable Motivations

OBJECTIVE

To investigate differences in motivation perceptions toward exercise per self-determination theory and theory of planned behavior between active and insufficiently active persons with multiple sclerosis, given the well-being enhancements associated with exercise engagement for this population.

DESIGN

Cross-sectional between-groups design where active persons ≥14 points on the Godin Leisure Time Exercise Questionnaire, and insufficiently active <14.

SETTING

Community setting in Australia.

PARTICIPANTS

Australian participants (N=70; mean age, 49.61±12.79y; FIM 64:6; Patient Disability Disease Steps median, 3).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Godin Leisure Time Exercise Questionnaire and adaptations of the self-determination theory (autonomous and controlling forms of motivation) and the Theory of Planned Behavior (attitudes to exercise, subjective norms to exercise, behavioral control to exercise, intention to exercise) items tailored toward exercise perceptions.

RESULTS

Active persons perceived higher ratings compared with insufficiently active persons of autonomous motivations toward their exercise d=0.85 in addition to positive attitudes toward the value of exercise d=1.28, their behavioral control over exercise d=1.86, and their enhanced intentions to engage in exercise d=1.14. All effect sizes were large (d>0.80).

CONCLUSIONS

These findings suggest the value of considering ways of enhancing the perceived autonomy toward engaging in physical activity in addition to the reduction of barriers toward participating and enhancing positive attitudes toward the value of physical activity when practitioners are working with persons living with multiple sclerosis.

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.

The Relationship between Physical Activity Levels and Mental Health in Individuals with Spinal Cord Injury in South Korea

Background: The aim of this study was to assess the relationship between physical activity (PA) levels and mental health in individuals with spinal cord injury (SCI). Methods: Three hospitals in the Seoul metropolitan area were invited to recruit patients with SCI (n = 103). PA levels were measured by the Leisure Score Index of the Godin Leisure-Time Exercise Questionnaire (GLTEQ). The Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder-7 (GAD-7) questionnaire, and Multidimensional Scale of Perceived Social Support (MSPSS) were used to assess mental health. Results: Compared to the least physically active participants (1st tertile, 44.09 ± 52.74 min/week), the most physically active participants (3rd tertile, 670.86 ± 354.97 min/week) scored significantly lower on PHQ-9 (17.03 ± 5.70 vs. 12.49 ± 4.01, p < 0.001), GAD-7 (13.24 ± 4.78 vs. 9.86 ± 3.15, p < 0.001), while significantly higher MSPSS (51.24 ± 10.17 vs. 61.37 ± 11.90, p < 0.001) after the results were adjusted for age, gender, American Spinal Cord Injury Association impairment scale, and impaired spinal cord levels. Multivariate linear regression analysis showed that the PA was a significant predictor of depression (β = −1.50, p = 0.01), anxiety (β = −1.12, p = 0.02), and social support (β = 4.04, p = 0.01). Conclusion: Higher PA participation was associated with lower depression, anxiety, and higher social support scores.

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.

Center-Based Group and Home-Based Individual Exercise Programs Have Similar Impacts on Gait and Balance in People With Multiple Sclerosis: A Randomized Trial

BACKGROUND

Group and home-based exercises to improve function in people with multiple sclerosis (MS) are common but have little underpinning evidence.

OBJECTIVE

To determine the comparative effectiveness of a center-based group versus home-based individual 8-week exercise program to improve gait and balance in people with MS.

DESIGN

Prospective, randomized controlled trial.

SETTING

Community center-based and home-based exercise program.

PARTICIPANTS

Fifty people with MS were randomized and completed allocated intervention (n = 26 center, n = 24 home), 47 completed post-assessment and 44 follow-up assessment.

METHODS

The center- and home-based groups completed an 8-week progressive functional and balance training exercise program. The center-based groups of four to six were supervised by a physiotherapist. The home-based group was provided with telephone support.

MAIN OUTCOME MEASUREMENTS

The primary outcome was gait speed (10-meter walk test). Secondary outcomes were gait endurance (6-minute walk test) and balance (Berg Balance Scale). Outcome assessments were conducted at baseline, immediately postintervention and at 8-week follow-up.

RESULTS

There was no statistically significant difference between groups in gait speed post training, with a mean difference of 0.01 m/s, 95% CI -0.36 to 0.37. There were no group effects, time effects, or interactions for gait speed, endurance, or balance. In both groups, gait speed improved to a level that met minimal clinically important differences.

CONCLUSIONS

Gait speed, endurance, and balance did not statistically improve in either group; however, gait speed changes met minimally important differences.

'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.

Self-regulation mechanisms in health behavior change: a systematic meta-review of meta-analyses, 2006-2017

Self-regulation is one primary mechanism in interventions for health behavior change and has been examined in numerous recent meta-analyses. This pre-registered meta-review (PROSPERO CRD42017074018) examined Mmeta-analyses of any intervention and health behavior/outcome were eligible if they quantitatively assessed self-regulation and appeared between January 2006 and August 2017. In total, 66 meta-analyses were ultimately eligible; 27% reported a protocol, 11% used GRADE; 58% focused on RCTs. Reviews satisfied only a moderate number of items on the AMSTAR 2 (M = 45.45%, SD = 29.57%). Only 6% of meta-analyses directly examined whether changes in self-regulation predicted the behavior change (i.e., self-efficacy and physical activity, l = 2; frequency of self-monitoring and goal attainment, l = 1; cognitive bias modification and addiction, l = 1). Meta-analyses more routinely assessed self-regulation by comparing the efficacy of intervention components (97%), such as those from behavior change taxonomies. Meta-analyses that focused on intervention components identified several as successful, including personalized feedback, goal setting, and self-monitoring; however, none were consistently successful in that each worked only for some health behaviors and with particular populations. Some components had inconclusive evidence, given that they were only examined in low- quality reviews. Future reviewers should utilize advanced methods to assess mechanisms, and study authors should report hypothesized mechanisms to facilitate synthesis.

Social Cognitive Theory and Physical Activity in Older Adults with Multiple Sclerosis

Background

The expanding population of older adults with multiple sclerosis (MS) likely experiences many of the same benefits of physical activity (PA) as younger and middle-aged adults with MS. However, participation in PA is exceedingly low in this segment of the MS population. This study examined variables from social cognitive theory (SCT) as correlates of PA in older adults with MS to inform the subsequent development of behavioral interventions.

Methods

Older adults with MS (≥60 years of age, N = 180) completed an online survey including demographic and clinical characteristics, SCT variables (exercise self-efficacy, exercise goal setting, social support, and outcome expectations), and PA (total PA [TPA] and moderate-to-vigorous PA [MVPA]).

Results

Bivariate correlation analyses indicated that all SCT variables were significantly associated with TPA and MVPA (all P ≤ .001). Hierarchical linear regression analyses indicated that disability status was a significant correlate of TPA (β = -0.48, R² = 0.23) and MVPA (β = -0.44, R² = 0.19) in step 1; disability and self-efficacy were significant correlates of TPA (disability β = -0.20, self-efficacy β = 0.59, R² = 0.50) and MVPA (disability β = -0.16, self-efficacy β = 0.60, R² = 0.47) in step 2; and disability, self-efficacy, and exercise goal setting were significant correlates of TPA (disability β = -0.21, self-efficacy β = 0.50, exercise goal setting β = 0.14, R² = 0.55) and MVPA (disability β = -0.17, self-efficacy β = 0.51, exercise goal setting β = 0.15, R² = 0.51) in step 3.

Conclusions

These results suggest that behavioral interventions focusing on self-efficacy and exercise goal setting as targets from SCT may be appropriate for increasing PA in older adults with MS.

Physical activity participation according to the pyramidal, sensory, and cerebellar functional systems in multiple sclerosis

The objective of the study was to examine the differences in physical activity participation with the pyramidal, cerebellar, and sensory functional systems in people with multiple sclerosis (PwMS). This cross-sectional study included 289 PwMS with a median EDSS of 2.0 (range 0-6.5) and a mean disease duration of 6.8 (SD = 8.4) years. The Godin leisure-time exercise questionnaire (GLTEQ) assessed physical activity participation. The sample was divided into seven groups according to the pyramidal, cerebellar, and sensory functional system scores derived from the EDSS data. Additionally, PwMS were divided into three physical activity subgroups (active, moderately active, and insufficiently active). Furthermore, PwMS were categorized into four levels of disability based on their global Expanded Disability Status Scale (EDSS) score [very mild (0-1.5), mild (2.0-3.5), moderate (4.0-5.5), and severe (6.0-6.5)]. In the physical activity subgroups, 159 (55.0%) were classified as insufficiently active, 59 (20.4%) as moderately active, and 71 (24.6%) as active. Pyramidal, cerebellar, and sensory impairments were demonstrated in 134 (46.4%), 73 (25.3%), and 85 (29.4%) patients, respectively. No differences were found for the GLTEQ scores for all seven functional system groups (P value = 0.168). As for the EDSS disability subgroups, the percentage of active patients (moderately at least) were 60%, 45.8%, 36.5%, and 15.4%, for the very mild, mild, moderate, and severe subgroups, respectively. This study found that participation in leisure-time physical activity is independent from the pyramidal, cerebellar, and sensory functional systems in PwMS.

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

BACKGROUND

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

METHODS/DESIGN

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

DISCUSSION

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

Physical activity in mild multiple sclerosis: contribution of perceived fatigue, energy cost, and speed of walking

Purpose: To clarify the relationship between leisure-time physical activity, perceived fatigue, and energy expenditure while walking in people with multiple sclerosis.Methods: Sixty-six people afflicted with multiple sclerosis (MS) (32 women) with a mild neurological disability, participated in this study. Energy expenditure was separately measured at rest, during comfortable walking and during fast walking via a portable metabolic device using breath-by-breath technology (COSMED K5, COSMED Srl, Rome, Italy). The Godin leisure-time exercise questionnaire assessed leisure-time physical activity. The Modified Fatigue Impact Scale determined the level of perceived fatigue.Results: Seventeen people with MS were classified as physically active; 49 were insufficiently active. Scores recorded on the Godin Leisure-Time Exercise Questionnaire were 47.8 (SD = 18.4), 7.0 (SD = 8.2), respectively. Insufficiently physically active people with MS walked slower at both normal and fast walking conditions. However, no differences between groups were observed in energy expenditure measures in both walking speeds. O₂ cost was 0.20 (SD = 0.13) and 0.21 (SD = 0.06) in the active and insufficiently active group, respectively. The insufficiently active group reported more perceived fatigue compared with the active patients; 33.3 (SD = 18.6) vs. 15.0 (SD = 19.0), p value = 0.002. Perceived fatigue was a significant variable maintaining a 10.4% variance related to leisure-time physical activity.Conclusions: Leisure-time physical activity was inversely associated with perceived fatigue and walking speed in persons with mild MS. Rehabilitation professionals should be aware of these relationships when planning rehabilitation strategies.Implication for rehabilitationThis study found that perceived fatigue is a barrier to physical activity participation even in people with mild multiple sclerosis and minimal disability.Insufficiently active people with multiple sclerosis expend the same amount of energy while walking as active multiple sclerosis individuals, though walking slower.The relationship between perceived fatigue and physical activity participation requires further exploration in the multiple sclerosis population.

Associations between activity and participation in adults with multiple sclerosis: a cross sectional study

OBJECTIVES

The aim of this study was to determine the association between walking ability in a clinical setting (activity capacity), walking ability in a person's daily environment (activity capability) and walking performance in daily life (activity performance), and the contribution of each activity construct to participation among people with multiple sclerosis (MS).

DESIGN

Cross-sectional study.

SETTING

Five MS therapy centres in England.

PARTICIPANTS

Fifty-two adults (13 males) with MS who were independently ambulatory with or without a walking aid (mean (SD) age 55.4 (9.1) year).

INTERVENTIONS

No intervention.

MAIN OUTCOME MEASURES

Activity capacity, capability, and performance were assessed using the Six Minute Walk Test (6MWT), Twelve Item MS Walking Scale (MSWS-12), and steps/day measured using a pedometer worn for 6 days, respectively. Participation was assessed using the Impact on Participation and Autonomy questionnaire (IPA).

RESULTS

Distance walked on the 6MWT was associated with MSWS-12 score (β=-0.56, 95% CI -0.87 to -0.22) and steps/day (β=129.49, 95% CI 48.48 to 207.57). MSWS-12 score was also associated with step count (β=-87.35, 95% CI -172.29 to -15.71). 6MWT distance was associated with the autonomy indoors subscale of the IPA (β=-0.02, 95% CI -0.04 to -0.01). No other activity measure was associated with participation.

CONCLUSIONS

Findings suggest that while activity capacity, capability and performance are related, activity is a poor predictor of participation. The strength of associations between constructs of activity, and activity and participation, however, are often small with wide confidence intervals, indicating that there is considerable uncertainty associated with effect estimates.

Fear of falling, not falls, impacts leisure-time physical activity in people with multiple sclerosis

BACKGROUND

There is a consensus that physical activity is imperative for people with MS (PwMS). However, regardless of the benefits, many PwMS do not participate in any meaningful physical activity.

AIM

To examine the relationship between leisure-time physical activity with clinical characteristics and common symptoms in PwMS.

METHODS

The sample included 190 PwMS (107 women), mean age 40.8 (S.D = 13.1) and mean disease duration of 6.4 (SD = 8.3) years since diagnosis. Outcome measures included the Godin Leisure-Time Exercise Questionnaire (GLTEQ), Four Square Step Test (FSST), 2-Minute Walk test (2 mWT), Timed Up and Go test (TUG), Timed 25-Foot Walk test (T25FW), fall status, Falls Efficacy Scale International (FES-I), Modified Fatigue Impact Scale (MFIS), walking speed and the Multiple Sclerosis Walking Scale self-reported questionnaire (MSWS-12).

RESULTS

Eighty-six PwMS were classified as active (GLTEQ = 31.6 (S.D = 16.7); 104 were insufficiently active (GLTEQ = 3.0 (S.D = 4.3). Insufficiently active PwMS demonstrated a slower walking speed, elevated fatigue, more concerns of falling and additional walking difficulties compared to active PwMS. Non-significant differences between groups were observed in the TUG, 2 mWT, FSST, T25FWT and fall status. According to the linear regression, by utilizing the FES-I we observed a 12.2% variance related to leisure-time physical activity. The independent variables: EDSS, MSWS-12, fatigue and walking speed were non-significant.

SIGNIFICANCE

The present findings highlight the impact of concern of falling on physical activity in PwMS. This knowledge may represent an opportunity to improve care and enhance physical activity in the MS population.

Acceptability and experience of a functional training programme (ReTrain) in community-dwelling stroke survivors in South West England: a qualitative study

Rehabilitation Training (ReTrain) is a group-based approach to functional training post stroke. ReTrain has recently been evaluated through a pilot randomised controlled trial.

OBJECTIVE

This article reports on the acceptability of the intervention as described by trial participants.

DESIGN

A qualitative approach was undertaken. Of the 45 participants recruited into the trial, 23 were randomised to receive ReTrain. Following a sampling strategy, 10 participants undertook 1:1 semistructured audio-recorded interviews. Transcripts were analysed following a modified Framework Approach.

RESULTS

Six themes were developed including exploration of: the physical and psychological impacts of training,the perceived mechanisms of change, the interaction of the group and approach of the trainer. A further theme considered the reported longer term impact of participation. Overall, the results indicated the acceptability of the intervention, but also key areas for potential modification in the definitive trial. These include a need to consider potential impact on both physical and psychological function, careful consideration of dosing and fatigue and the interpersonal factors that facilitate appropriate level of delivery, the trainer to participant ratio, and enhancing features that support continuation of activity postintervention.

CONCLUSION

Overall, this study supports the acceptability of ReTrain and the development of a definitive trial evaluation of this intervention to full.

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

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

Randomised controlled pilot trial of an exercise plus behaviour change intervention in people with multiple sclerosis: the Step it Up study

OBJECTIVE

To investigate feasibility of multiple sclerosis (MS) exercise guidelines for inactive people with MS (PwMS) and to examine preliminary efficacy for walking. To investigate effect of augmenting that intervention with education based on social cognitive theory (SCT).

DESIGN

Pilot multicentre, double-blind, randomised, parallel, controlled trial.

SETTING

Community-delivered programme.

PARTICIPANTS

Sixty-five physically inactive PwMS walked independently, scored 0-3 on the Patient Determined Disease Steps Scale, had no MS relapse or change in MS medication in 12 weeks.

INTERVENTIONS

10-week exercise plus SCT education (SCT) compared with exercise plus attention control education (CON).

OUTCOME MEASURES

Six-Minute Walk Test (6MWT), Timed Up and Go (TUG) test and Multiple Sclerosis Walking Scale-12 (MSWS-12).

RESULTS

174 expressed interest, 92 were eligible and 65 enrolled (SCT, n=32; CON, n=33). The intervention was feasible and delivered as intended. 68% of SCT group and 50% of control group met the exercise guidelines after intervention. Using linear mixed effects models, intention-to-treat basis, there was insufficient evidence for difference between the groups over the trial (6MWT, p=0.30; TUG, p=0.4; MSWS-12, p=0.8). Using secondary analysis of a cohort with data for≥3 assessments (SCT, n=21; CON, n=20), there was significant treatment effect favouring the intervention group (p=0.04) with mean effect for 6MWT 39.0 m (95% CI 2.26 to 75.73) at 12 weeks and 40.0 m (95% CI 2.3 to 77.8) at 36 weeks. Both groups improved significantly in 6MWT following 10-week intervention (SCT, mean ∆=83.02, SD=60.1, p≤0.01; CON, mean ∆=56.92, SD=73.5, p≤0.01), TUG (SCT, ∆=-0.70, SD=1.25, p≤0.01; CON, ∆=-0.54, SD=0.95, p≤0.01) and MSWS-12 (SCT, ∆=-8.03, SD=16.18, p=0.02; CON, ∆=-0.86, SD=18.74, p=0.81).

CONCLUSIONS

A 10-week exercise programme based on the MS exercise guidelines for improving walking in previously inactive PwMS was feasible. There is marginal evidence of a treatment effect in favour of the exercise plus SCT intervention at 12 and 36 weeks.

Effect of exercising at minimum recommendations of the multiple sclerosis exercise guideline combined with structured education or attention control education - secondary results of the step it up randomised controlled trial

BACKGROUND

Recent exercise guidelines for people with multiple sclerosis (MS) recommend a minimum of 30 min moderate intensity aerobic exercise and resistance exercise twice per week. This trial compared the secondary outcomes of a combined 10-week guideline based intervention and a Social Cognitive Theory (SCT) education programme with the same exercise intervention involving an attention control education.

METHODS

Physically inactive people with MS, scoring 0-3 on Patient Determined Disease Steps Scale, with no MS relapse or change in MS medication, were randomised to 10-week exercise plus SCT education or exercise plus attention control education conditions. Outcomes included fatigue, depression, anxiety, strength, physical activity, SCT constructs and impact of MS and were measured by a blinded assessor pre and post-intervention and 3 and 6 month follow up.

RESULTS

One hundred and seventy-four expressed interest, 92 were eligible and 65 enrolled. Using linear mixed effects models, the differences between groups on all secondary measures post-intervention and at follow-up were not significant. Post-hoc, exploratory, within group analysis identified improvements in both groups post intervention in fatigue (mean ∆(95% CI) SCT -4.99(-9.87, -0.21), p = 0.04, Control -7.68(-12.13, -3.23), p = 0.00), strength (SCT -1.51(-2.41, -0.60), p < 0.01, Control -1.55(-2.30, -0.79), p < 0.01), physical activity (SCT 9.85(5.45, 14.23), p < 0.01, Control 12.92(4.69, 20.89), goal setting (SCT 7.30(4.19, 10.4), p < 0.01, Control 5.96(2.92, 9.01), p < 0.01) and exercise planning (SCT 5.88(3.37, 8.39), p < 0.01, Control 3.76(1.27, 6.25), p < 0.01) that were maintained above baseline at 3 and 6 month follow up (all p < 0.05). Only the SCT group improved at 3 and 6 month follow up in physical impact of MS(-4.45(-8.68, -0.22), -4.12(-8.25, 0.01), anxiety(-1.76(-3.20, -0.31), -1.99(-3.28, -0.71), depression(-1.51(-2.89, -0.13), -1.02(-2.05, 0.01)) and cognition(5.04(2.51, 7.57), 3.05(0.81, 5.28), with a medium effect for cognition and fitness (Hedges' g 0.75(0.24, 1.25), 0.51(0.01, 1.00) at 3 month follow up.

CONCLUSIONS

There were no statistically significant differences between groups for the secondary outcomes once age, gender, time since diagnosis and type of MS were accounted for. However, within the SCT group only there were improvements in anxiety, depression, cognition and physical impact of MS. Exercising at the minimum guideline amount has a positive effect on fatigue, strength and PA that is sustained at 3 and 6 months following the cessation of the program.
