Client Perceptions of the Individual Packer Managing Fatigue Program: A Mixed-Method Evaluation

Fatigue is common, but under-recognized in Parkinson's disease (PD), with limited treatment options. The aim of this study is to explore the experience of people with PD (PwPD) regarding content and delivery of the individual Packer Managing Fatigue program. This mixed-method study (n = 12) was conducted concurrently with a pilot randomized controlled trial. Data were collected using questionnaires, interviews, and focus groups. Five themes emerged: the program is helpful; the program has strengths; areas for improvement; individual online delivery is feasible; and more support from occupational therapist would be helpful. Quantitative findings confirmed feasibility with high ratings on questionnaires and confidence to use learned strategies. The findings inform future implementation of the Packer Managing Fatigue program and contribute to understanding the needs of PwPD. Future studies might explore program's effectiveness as stand-alone treatment or in combination with other approaches. Tailoring fatigue programs to PwPD's unique needs and characteristics of PD fatigue is suggested.

Education for fatigue management in people with multiple sclerosis: Systematic review and meta-analysis

BACKGROUND AND PURPOSE

Fatigue is a common and disabling symptom in multiple sclerosis (MS). Educational interventions have shown potential to reduce fatigue. The aim was to systematically review the current best evidence on patient education programmes for MS-related fatigue.

METHODS

This was a systematic review and meta-analysis following Cochrane methodology. A systematic search was conducted in eight databases (September 2023). Moreover, reference lists and trial registers were searched and experts in the field were contacted. Randomized controlled trials were included evaluating patient education programmes for people with MS with the primary aim of reducing fatigue.

RESULTS

In total, 1176 studies were identified and assessed by two independent reviewers; 15 studies (1473 participants) were included. All interventions provided information and education about different aspects of MS-related fatigue with different forms of application, some with components of psychological interventions. Amongst those, the most frequently applied were cognitive behavioural therapy (n = 5) and energy-conservation-based approaches (n = 4). Studies differed considerably concerning mode of intervention delivery, number of participants and length of follow-up. Interventions reduced fatigue severity (eight studies, n = 878, standardized mean difference -0.28; 95% confidence interval -0.53 to -0.03; low certainty) and fatigue impact (nine studies, n = 824, standardized mean difference -0.21; 95% confidence interval -0.42 to 0.00; moderate certainty) directly after the intervention. Mixed results were found for long-term effects on fatigue, for secondary endpoints (depressive symptoms, quality of life, coping) and for subgroup analyses.

CONCLUSION

Educational interventions for people with MS-related fatigue may be effective in reducing fatigue in the short term. More research is needed on long-term effects and the importance of specific intervention components, delivery and context.

Fatigue in multiple sclerosis: can we measure it and can we treat it?

Fatigue is a common and debilitating symptom in multiple sclerosis (MS). However, after over 100 years of inquiry its definition, measurement and understanding remains elusive. This paper describes the challenges clinicians and researchers face when assessing and treating MS patients, as well as our understanding of neural mechanisms involved in fatigue. Challenges for the future are discussed.

Fatigue in patients with acquired brain damage

Fatigue is a complex, multidimensional syndrome that is prevalent in patients with acquired brain damage and has a negative impact on the neurorehabilitation process. It presents from early stages after the injury, and may persist over time, regardless of whether sequelae have resolved. Fatigue is conditioned by upper neuronal circuits, and is defined as an abnormal perception of overexertion. Its prevalence ranges from 29% to 77% after stroke, from 18% to 75% after traumatic brain injury, and from 47% to 97% after brain tumours. Fatigue is associated with factors including female sex, advanced age, dysfunctional families, history of specific health conditions, functional status (eg, fatigue prior to injury), comorbidities, mood, secondary disability, and the use of certain drugs. Assessment of fatigue is fundamentally based on such scales as the Fatigue Severity Scale (FSS). Advances have recently been made in imaging techniques for its diagnosis, such as in functional MRI. Regarding treatment, no specific pharmacological treatment currently exists; however, positive results have been reported for some conventional neurorehabilitation therapies, such as bright light therapy, neurofeedback, electrical stimulation, and transcranial magnetic stimulation. This review aims to assist neurorehabilitation professionals to recognise modifiable factors associated with fatigue and to describe the treatments available to reduce its negative effect on patients.

Efficacy of rehabilitation interventions evaluated in common neurological conditions in improving participation outcomes: A systematic review

OBJECTIVE

Modern clinical rehabilitation practice aligned to the International Classification of Functioning, Disability and Health and the Convention on the Rights of Persons with Disabilities highlights the importance of attention to participation in the rehabilitation formulation. This systematic review investigates the efficacy of rehabilitation interventions evaluated in common neurological disorders reported to influence participation outcomes.

DATA SOURCES

PubMed, Web of Science and PsycINFO databases were searched from inception to 25 April 2023. Only randomised controlled trials were considered for inclusion.

REVIEW METHODS

The data were extracted by two independent reviewers in the following categories: characteristics of the included study publications, description of intervention and outcome measures.

RESULTS

A total of 1248 unique article records were identified through the databases. Twenty-eight randomized controlled trials were included with 15 publications having participation as a primary outcome measure. Articles were related to multiple sclerosis (N = 4), spinal cord injury (N = 2), stroke (N = 16) and traumatic brain injury (N = 6). Four publications showed significant differences in pre- and post-intervention within experimental groups. All four articles described participation as primary outcome measure.

CONCLUSION

There is a limited evidence of the identified rehabilitation interventions to improve participation in common neurological conditions. However, there was a paucity of articles involving individual with Parkinson's disease that met the inclusion criteria.

Unraveling the interplay between daily life fatigue and physical activity after subarachnoid hemorrhage: an ecological momentary assessment and accelerometry study

BACKGROUND

Fatigue is one of the most commonly reported symptoms after subarachnoid hemorrhage (SAH) and is indirectly associated with physical activity (PA). Associations between fatigue and PA are primarily examined based on conventional measures (i.e. a single fatigue score or average PA levels), thereby assuming that fatigue and PA do not fluctuate over time. However, levels of fatigue and PA may not be stable and may interrelate dynamically in daily life. Insight in direct relationships between fatigue and PA in daily life, could add to the development of personalized rehabilitation strategies. Therefore we aimed to examine bidirectional relationships between momentary fatigue and PA in people with SAH.

METHODS

People (n = 38) with SAH who suffer from chronic fatigue were included in an observational study using Ecological Momentary Assessment (EMA) and accelerometry. Momentary fatigue was assessed on a scale from 1 to 7 (no to extreme fatigue), assessed with 10-11 prompts per day for 7 consecutive days using EMA with a mobile phone. PA was continuously measured during this 7-day period with a thigh-worn Activ8 accelerometer and expressed as total minutes of standing, walking, running and cycling in a period of 45 min before and after a momentary fatigue prompt. Multilevel mixed model analyses including random effects were conducted.

RESULTS

Mean age was 53.2 years (SD = 13.4), 58% female, and mean time post SAH onset was 9.5 months (SD = 2.1). Multilevel analyses with only time effects to predict fatigue and PA revealed that fatigue significantly (p < 0.001) increased over the day and PA significantly (p < 0.001) decreased. In addition, more PA was significantly associated with higher subsequent fatigue (β = 0.004, p < 0.05) and higher fatigue was significantly associated with less subsequent PA (β=-0.736, p < 0.05). Moreover, these associations significantly differed between participants (p < 0.001).

CONCLUSIONS

By combining EMA measures of fatigue with accelerometer-based PA we found that fatigue and PA are bidirectionally associated. In addition, these associations differ among participants. Given these different bidirectional associations, rehabilitation aimed at reducing fatigue should comprise personalized strategies to improve both fatigue and PA simultaneously, for example by combining exercise therapy with cognitive behavioral and/or energy management therapy.

What we know about fatigue self-management programs for people living with chronic conditions: A scoping review

OBJECTIVE

The significant impact of fatigue on the lives of patients with chronic conditions has demanded a response. One response has been the development and testing of self-management programs. Little is known about what these programs have in common or how they differ. This scoping review compared the key components of fatigue self-management programs.

METHODS

Scoping review methodology was employed. Databases of CINAHL, Academic Search Premier, PsycINFO, Cochrane and Medline were searched to identify relevant sources.

RESULTS

Included fatigue programs were compared using a three-component framework: 1) self-management strategies; 2) active patient participation; and 3) self-management support. Although all programs included some aspects of these components, the extent varied with only a few domains of these components found across all programs.

CONCLUSION

The three self-management components employed in this study showed potential benefits in identifying similarities and differences across fatigue programs with comparable and distinct underlying theories. This three-component framework could facilitate identification of domains associated with positive outcomes.

PRACTICE IMPLICATIONS

It is essential that authors of programs provide detailed descriptions to enable inter-program comparison. The three-component framework chosen for this review was capable of describing and comparing fatigue self-management programs, paving the way for more effective interventions.

The effect of distance nurse-led fatigue management on fatigue, sleep quality, and self-efficacy in patients with multiple sclerosis: a quasi-experimental study

BACKGROUND

Fatigue is one of the most common problems in patients with multiple sclerosis (MS) and has adverse effects on their sleep status and self-efficacy. This study aimed to determine the effect of distance nurse-led fatigue management on fatigue, sleep quality, and self-efficacy in patients with MS.

METHODS

This quasi-experimental study was performed on 60 patients with MS in Arak, Iran. Subjects were randomly assigned into intervention and control groups. The intervention group received eight sessions of nurse-led fatigue management training through the Skyroom platform. The control group received only the usual programs. Data were collected before and two months after the intervention using the Fatigue Severity Scale, the Pittsburgh Sleep Quality Index, and the Multiple Sclerosis Self-Efficacy Scale. The significance level in this study was determined 0.05.

RESULTS

After the intervention, the mean score of fatigue severity in the intervention group was significantly lower than the control group (2.52 ± 0.40 vs 5.65 ± 0.52) (P < 0.001). Also, after the intervention, the mean score of self-efficacy in the intervention group was significantly higher than the control group (49.37 ± 3.25 vs 24.43 ± 2.52) (P < 0.001). Furthermore, after the intervention the mean score of sleep quality was lower in intervention group (11.92 ± 2.01) than the control group (15.46 ± 1.40) (P < 0.001).

CONCLUSION

Distance nurse-led fatigue management improved fatigue, sleep quality, and self-efficacy in patients with MS. We recommend the use of these courses as an important step toward improving fatigue, sleep quality, and self-efficacy among these patients.

The relation between cognitive-behavioural responses to symptoms in patients with long term medical conditions and the outcome of cognitive behavioural therapy for fatigue - A secondary analysis of four RCTs

BACKGROUND

Cognitive behavioural therapy (CBT) is effective in reducing fatigue across long-term conditions (LTCs). This study evaluated whether cognitive and behavioural responses to symptoms: 1) differ between LTCs and 2) moderate and/or mediate the effect of CBT on fatigue.

METHOD

Data were used from four Randomized Controlled Trials testing the efficacy of CBT for fatigue in Chronic Fatigue Syndrome/ME (N = 240), Multiple Sclerosis (N = 90), Type 1 Diabetes Mellitus (N = 120) and Q-fever fatigue syndrome (N = 155). Fatigue severity, assessed with the Checklist Individual Strength, was the primary outcome. Differences in fatigue perpetuating factors, assessed with the Cognitive Behavioural Responses to Symptoms Questionnaire (CBRQ), between diagnostic groups were tested using ANCOVAs. Linear regression and mediation analyses were used to investigate moderation and mediation by CBRQ scores of the treatment effect.

RESULTS

There were small to moderate differences in CBRQ scores between LTCs. Patients with higher scores on the subscales damage beliefs and avoidance/resting behaviour at baseline showed less improvement following CBT, irrespective of diagnosis. Reduction in fear avoidance, catastrophising and avoidance/resting behaviour mediated the positive effect of CBT on fatigue across diagnostic groups.

DISCUSSION

The same cognitive-behavioural responses to fatigue moderate and mediate treatment outcome across conditions, supporting a transdiagnostic approach to fatigue.

Energy conservation, minimum steps, and adaptations when needed: A scoping review

Background/objective

Although many therapeutic approaches use energy conservation, only a few effectively report the steps involved. Thus, it is intended to identify energy conservation practices to be organized in flexible and adaptable stages.

Methods

A scoping review was carried out, whose search strategies were applied in seven databases (CINAHL, Cochrane Library, Portal BVS, PsycINFO, PubMed, Scopus, and Web of Science) following guidelines by Arksey and O’Malley on the Rayyan software. Searches were carried out from January 2010 to December 2020. Inclusion of refered publications with different study designs, participation of adults with or by demands of energy conservation, joint protection, and control of fatigue and/or pain. Exclusion of productions without an occupational therapist or involving merely pharmacological or surgical therapeutic strategies.

Results

653 articles were identified, after the selection and eligibility steps, 30 articles were full review, 18 articles were included and 635 excluded. Energy conservation studies have been increasingly focusing on neurological and systemic diseases, especially regarding symptoms of fatigue and pain. The findings were arranged in six strategies whose interventions are essentially based on guidelines and setting goals for patients, client-centered approach. Merely supervised interventions are less frequent. The number of sessions is closed, but the duration of treatment is not yet.

Conclusions

The signs of pain and fatigue are confirmed as indicators of energy conservation strategies, this delivery can be condensed from planning and organization, priorities, activity analysis, balance between activity and rest, outsourcing of tasks and physical/environmental adaptation.

Fatigue self-management led by occupational therapists and/or physiotherapists for chronic conditions: A systematic review and meta-analysis

OBJECTIVE

The aim of this study was to investigate the effectiveness of occupational therapist-/physiotherapist-guided fatigue self-management for individuals with chronic conditions.

METHODS

Eight databases, including MEDLINE and EMBASE, were searched until September 2019 to identify relevant studies. Randomised controlled trials and quasi-experimental studies of self-management interventions specifically developed or delivered by occupational therapists/physiotherapists to improve fatigue symptoms of individuals with chronic conditions were included. A narrative synthesis and meta-analysis were conducted to determine the effectiveness of fatigue self-management.

RESULTS

Thirty-eight studies were included, and fatigue self-management approaches led by occupational therapists/physiotherapists were divided into six categories based on the intervention focus: exercise, energy conservation, multimodal programmes, activity pacing, cognitive-behavioural therapy, and comprehensive fatigue management. While all exercise programmes reported significant improvement in fatigue, other categories showed both significant improvement and no improvement in fatigue. Meta-analysis yielded a standardised mean difference of the overall 13 studies: 0.42 (95% confidence interval:-0.62 to - 0.21); standardised mean difference of the seven exercise studies was -0.55 (95% confidence interval: -0.78 to -0.31).

DISCUSSION

Physical exercises inspired by the self-management principles may have positive impacts on fatigue symptoms, quality of life, and other functional abilities.

Fatigue self-management education in persons with disease-related fatigue: A comprehensive review of the effectiveness on fatigue and quality of life

OBJECTIVES

To systematically synthesize the effectiveness of fatigue self-management education (SME) on fatigue and quality of life (QoL) in persons with disease-related fatigue, and to describe the intervention characteristics.

METHODS

We systematically reviewed the literature on SMEs in people with disease-related fatigue. We included randomized controlled trials (RCT), which aimed to improve self-management skills for fatigue in daily life. We synthesized the effectiveness and mapped the intervention characteristics.

RESULTS

We included 26 RCTs studying samples from eight disease groups. At follow-up, 46% studies reported statistically significant improvements on fatigue and 46% on QoL. For persons with cancer 6/8 and multiple sclerosis 8/10 RCTs showed positive evidence in favor of SME. The range of effect sizes was wide (d: 0.0 ->0.8). Delivery modalities (inpatient, outpatient, home), interactions (individual, group, remote), and duration [range (h): 1-17.5] varied.

CONCLUSIONS

The overall evidence on the effectiveness of SMEs on fatigue and QoL is limited and inconsistent. For persons with cancer and multiple sclerosis, the evidence provides a positive effect. The RCTs with medium to large effect on QoL indicate the potential benefit of SMEs.

PRACTICAL IMPLICATION

Duration and peer interaction should be considered when tailoring SMEs to populations and contexts.

Managing Fatigue in Parkinson's Disease: Protocol for a Pilot Randomized Controlled Trial

Background. Fatigue is a disabling symptom of Parkinson’s disease (PD). Managing Fatigue: A Six-Week Energy Conservation Intervention was developed to improve the occupational performance of people with fatigue. Efficacy of this program has not been established in PD. Purpose. This study will assess feasibility of the Managing Fatigue: Individual Program (MFIP) delivered via videoconference, the Randomized Controlled Trial (RCT) protocol, and the preliminary effectiveness of the MFIP. Methods. A mixed-methods approach nested in a pilot RCT, randomizing 54 participants 1:1 to usual care or MFIP arms, will be employed to evaluate the feasibility and preliminary effectiveness of MFIP. Qualitative and quantitative data will be collected simultaneously. Implications. Results will identify evidence for establishing protocol requirements for a full-scale RCT. Knowledge of the effectiveness of the one-to-one videoconference delivery format of the program has the potential to enhance the accessibility and the quality of care of the PD population.

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

IMPORTANCE

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

OBJECTIVE

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

DATA SOURCES

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

FINDINGS

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

CONCLUSIONS AND RELEVANCE

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

Energy conservation education intervention for people with end-stage kidney disease receiving haemodialysis (EVEREST): protocol for a cluster randomised control trial

INTRODUCTION

Multiple symptoms occur in people with kidney failure receiving haemodialysis (HD) and these symptoms have a negative impact on health-related quality of life (HRQoL). Fatigue, the most common symptom, is debilitating and difficult to manage. Educational interventions involving energy conservation strategies are helpful in reducing fatigue, however the effectiveness of energy conservation has not been previously studied in those receiving HD. The aim of this study is to evaluate the effectiveness of an energy conservation education intervention for people with end-stage kidney disease receiving HD (EVEREST trial).

METHODS AND ANALYSIS

A pragmatic cluster randomised control trial with repeated measure will be used. One hundred and twenty-six participants from tertiary level dialysis centre will be cluster randomised to the intervention and control group according to HD treatment day. The intervention group will receive usual care along with a structured energy conservation education programme over 12 weeks comprising three individual face-to-face educational intervention sessions, one booster session and a booklet. The control group will receive usual care from their healthcare providers and a booklet at the end of the study. The primary outcome is fatigue, and the secondary outcomes are other Chronic Kidney Disease (CKD) symptoms, occupational performance and HRQoL. Intention-to-treat analysis will occur and will include a change in primary and secondary outcomes.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Human Research Committee of the Griffith University and Nepal Health Research Council. The results of this research will be published and presented in a variety of forums.

E-nergEYEze, a vision-specific eHealth intervention based on cognitive behavioral therapy and self-management to reduce fatigue in adults with visual impairment: study protocol for a randomized controlled trial

Background

More than half of the adults with visual impairment experience severe symptoms of fatigue, with a negative impact on daily life. Since there is no evidence-based treatment to reduce fatigue in adults with visual impairment, we developed E-nergEYEze, an eHealth intervention based on cognitive behavioral therapy and self-management tailored to the needs of visually impaired adults. The aim is to describe the study protocol of a randomized controlled trial testing E-nergEYEze.

Methods

A randomized controlled trial will be conducted to investigate the cost-effectiveness and cost-utility of E-nergEYEze to reduce fatigue severity compared to care as usual from a healthcare and societal perspective. A total of 172 severely fatigued adults with visual impairment will be recruited and randomized to either the E-nergEYEze intervention plus care as usual or to care as usual only (ratio 1:1). Inclusion criteria are having a visual impairment, experiencing severe fatigue (Checklist Individual Strength – subscale Fatigue Severity: CIS-FS > 35), being 18 years or older, understanding the Dutch language, and having access to the internet. The intervention consists of one face-to-face session and a computer training followed by internet-based modules with information and assignments on coping with fatigue. During this 5-month intervention, participants will be digitally supported by a social worker. All measurements will be administered at baseline, after 6 and 12 months, and additionally, those related to cost-effectiveness at 3 and 9 months. The primary outcome is fatigue severity (CIS-FS).

Discussion

Severe fatigue on top of visual impairment compromises quality of life and is associated with incremental societal costs that largely determine the economic burden of low vision or blindness. E-nergEYEze contributes to the evidence base of potentially feasible interventions to reduce the important health-related consequences of vision loss and could fulfill the gap in knowledge, skills and treatment options for low vision services.

Which exercise and behavioural interventions show most promise for treating fatigue in multiple sclerosis? A network meta-analysis

BACKGROUND

Fatigue is a common, debilitating symptom of multiple sclerosis (MS) without a current standardised treatment.

OBJECTIVE

The aim of this systematic review with network meta-analyses was to estimate the relative effectiveness of both fatigue-targeted and non-targeted exercise, behavioural and combined (behavioural and exercise) interventions.

METHODS

Nine electronic databases up to August 2018 were searched, and 113 trials (n = 6909) were included: 34 were fatigue-targeted and 79 non-fatigue-targeted trials. Intervention characteristics were extracted using the Template for Intervention Description and Replication guidelines. Certainty of evidence was assessed using GRADE.

RESULTS

Pairwise meta-analyses showed that exercise interventions demonstrated moderate to large effects across subtypes regardless of treatment target, with the largest effect for balance exercise (SMD = 0.84). Cognitive behavioural therapies (CBTs) showed moderate to large effects (SMD = 0.60), with fatigue-targeted treatments showing larger effects than those targeting distress. Network meta-analysis showed that balance exercise performed significantly better compared to other exercise and behavioural intervention subtypes, except CBT. CBT was estimated to be superior to energy conservation and other behavioural interventions. Combined exercise also had a moderate to large effect.

CONCLUSION

Treatment recommendations for balance and combined exercise are tentative as the certainty of the evidence was moderate. The certainty of the evidence for CBT was high.

Fatigue in patients with acquired brain damage

Fatigue is a complex, multidimensional syndrome that is prevalent in patients with acquired brain damage and has a negative impact on the neurorehabilitation process. It presents from early stages after the injury, and may persist over time, regardless of whether sequelae have resolved. Fatigue is conditioned by upper neuronal circuits, and is defined as an abnormal perception of overexertion. Its prevalence ranges from 29% to 77% after stroke, from 18% to 75% after traumatic brain injury, and from 47% to 97% after brain tumours. Fatigue is associated with factors including female sex, advanced age, dysfunctional families, history of specific health conditions, functional status (eg, fatigue prior to injury), comorbidities, mood, secondary disability, and the use of certain drugs. Assessment of fatigue is fundamentally based on such scales as the Fatigue Severity Scale (FSS). Advances have recently been made in imaging techniques for its diagnosis, such as in functional MRI. Regarding treatment, no specific pharmacological treatment currently exists; however, positive results have been reported for some conventional neurorehabilitation therapies, such as bright light therapy, neurofeedback, electrical stimulation, and transcranial magnetic stimulation. This review aims to assist neurorehabilitation professionals to recognise modifiable factors associated with fatigue and to describe the treatments available to reduce its negative effect on patients.

Physical activity and self-reported sleep quality in adults with multiple sclerosis

BACKGROUND

There is a fourfold higher prevalence of sleep problems in multiple sclerosis (MS) than the general population.

OBJECTIVE

This study examined cross-sectional associations among device-measured sedentary and physical activity behavior with perceived sleep quality in adults with MS.

METHODS

Adults with MS (N = 290) completed the Pittsburgh Sleep Quality Index (PSQI) and wore an accelerometer for seven days providing a measure of time spent in sedentary behavior, light physical activity (LPA), and moderate-to-vigorous physical activity (MVPA) using MS-specific cut-points. We conducted multiple linear regression analysis to identify the independent contributions of variables for explaining PSQI scores.

RESULTS

The overall model accounted for 2% of the variance in global PSQI scores, and MVPA was significantly and independently associated with global PSQI scores (β = ─0.123; p = 0.045; partial r = ─0.118) when accounting for average wear time, sedentary behavior, and time spent in LPA. There were no other significant associations with PSQI global score.

CONCLUSIONS

Our results suggest that time spent in MVPA may be associated with better sleep quality in adults with MS, but adults with MS do not spend sufficient time in physical activity. Researchers should evaluate these relationships in longitudinal study designs and behavior change interventions, as physical activity may provide a unique opportunity to improve sleep quality outcomes.

Participation and autonomy in the first 10 months after diagnosis of ALS: a longitudinal study

Introduction: More insight is needed into participation in daily activities and autonomy among patients with amyotrophic lateral sclerosis (ALS). Aims of this study were (1) to describe the course of participation restrictions and autonomy in participation during the first 10 months after diagnosis; (2) to study the influence of the rate of ALS progression on the course of participation. Methods: Secondary analysis of data from the longitudinal multicenter FACTS-2-ALS study. Self-report questionnaires were administered at inclusion (T0; n = 71), at 4 months (T1), 7 months (T2), 10 months (T3) after inclusion. Median duration of follow-up was 10.0 months. Participation restrictions were assessed using the sum of the Mobility Range and Social Behavior subscales of the Sickness Impact profile-68 (SIPSOC). Autonomy in participation was assessed using the Impact on Participation and Autonomy (IPA) Questionnaire. Fast disease progression was defined as an increase of 1.1 points per month or more on the ALS Functional Rating Scale. Results: Patients reported participation restrictions in all subscales while having mild physical limitations. There was a decrease of participation over time (restrictions and autonomy). This decrease was greatest in patients with fast disease progression. Disease progression negatively influenced movement-related participation more than social interaction domains. Rate of disease progression was more strongly related to SIPSOC scores compared to IPA scores. Discussion: Preserving participation may be an important determinant of quality of care for patients with ALS. Rate of progression of the disease should be taken into account as it was found to be significantly associated with the level of participation.

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.

Design considerations for a multiple sclerosis fatigue mobile app MS Energize: A pragmatic iterative approach using usability testing and resonance checks

Multiple sclerosis (MS) is a chronic neurological condition affecting around 2.2 million people worldwide. The illness includes a range of symptoms, with fatigue considered to be one of the most disabling. This paper describes how a pragmatic and iterative approach, supported by usability and resonance testing, was used to build a minimum viable product of MS Energize-or MS Energise in UK English regions. MS Energise is a mobile application focused on self-management of fatigue for people with MS. The iterative approach included various stages of testing, during which user feedback including comments about interface, navigation and content, was sought to inform incremental app development and continual improvement. Usability testing was conducted with 11 people with longstanding multiple sclerosis in New Zealand and the United Kingdom, and focused on particular sections of the app as well as the accessibility of the app to users with MS. Two participants contributed to further resonance testing post-release to ensure the app was perceived as relevant and useful to the user. The usability testing and resonance testing phases suggested that user experience of MS Energise was mostly positive. Participants provided a number of suggestions for improvements to aspects of content and design; some of which we implemented during our app development process. Findings will also contribute to future planning and design iteration to enhance the user experience. The next step is further improvement of MS Energise prior to a trial of its clinical and cost effectiveness.

Evidence-Based Rehabilitation for Multiple Sclerosis Made Easy: The Online Applying Evidence with Confidence (APPECO) Platform

With the current rate in growth of evidence in multiple sclerosis (MS) rehabilitation, systematic reviews and clinical guidelines typically lag behind the most currently published research findings. In addition, most health care professionals lack the time, resources, or adequate skills to identify and evaluate new evidence, and hands-on tools to implement the latest evidence into clinical practice are often lacking or not readily available. The Applying Evidence with Confidence (APPECO) platform is a newly developed online tool that addresses these key challenges. APPECO was initiated as a proof-of-concept for the common MS symptoms fatigue and cognitive function. Subsequently, intervention studies about depression, pain, and mobility were added. APPECO currently hosts detailed information from 250 randomized clinical trials, 293 interventions, and 1250 effect sizes on 53 patient outcomes. Few studies with high quality (ie, low risk of bias) are available specifically designed to test the benefits of MS rehabilitation on fatigue (n = 5 [2.4%]), cognitive function (n = 4 [1.6%]), and depression (n = 2 [0.8%]). No high-quality studies were included for pain and mobility. APPECO has the potential to address key challenges in evidence-based rehabilitation medicine for MS and to facilitate swift knowledge translation from evidence into clinical practice. Sustainability of APPECO depends on a continuous resource impulse (eg, financial, time, editorial management, platform maintenance) to ensure up-to-date information across all relevant MS symptoms and activity limitations (≈2-6 randomized controlled trials per month). Ways to optimize knowledge translation in the absence of high-quality evidence in APPECO need to be explored further.

[Effects of rehabilitation on fatigue, disability and quality of life in people with multiple sclerosis: A systematic review]

OBJECTIVE

To assess the effectiveness of rehabilitation, highlighting the role of Occupational Therapy, in people with multiple sclerosis, in terms of disability, fatigue and quality of life.

MATERIALS AND METHODS

A literature search was carried out in the BVS, Cochrane, OT-Seeker, PubMed and PEDro databases.

INCLUSION CRITERIA

Controlled clinical trials published between January 2011 and April 2019 in Spanish or English with a score of ≥5 on the PEDro scale whose purpose was rehabilitation through the use of assistive technology, skills training, vestibular rehabilitation, behaviour modification, therapeutic education or specific Occupational Therapy interventions.

RESULTS

A total of 16 studies (1,279 subjects) were included. Rehabilitation improved patients' fatigue and disability and slightly enhanced their quality of life.

CONCLUSIONS

Rehabilitation can provide benefits to the performance of people with multiple sclerosis by reducing their perceived fatigue and disability.

LIMITATIONS

The heterogeneity of the sample, the type and duration of the interventions and variability of the instruments for measuring results.

REFRESH protocol: a non-inferiority randomised clinical trial comparing internet and teleconference to in-person 'Managing Fatigue' interventions on the impact of fatigue among persons with multiple sclerosis

INTRODUCTION

Multiple sclerosis (MS) is an immune-mediated disease of the central nervous system. It is considered a major cause of non-traumatic disability in young adults. One of the most common and disabling symptoms of MS is fatigue. MS fatigue can impact all aspects of quality of life, including physical, mental and social function. Fortunately, fatigue self-management interventions, such as 'Managing Fatigue: A 6 week energy conservation course', can decrease the impact of fatigue and improve health-related quality of life. The purpose of this study is to compare three modes of delivering the Managing Fatigue intervention-two remote delivery formats (teleconference and internet) and one in-person format-on perceptions of fatigue and its impact on physical, mental and social function.

METHODS AND ANALYSIS

A non-inferiority randomised clinical trial is being conducted to compare the three delivery formats (1:1:1 allocation ratio) among 582 participants with MS living in the Midwestern and Northeastern United States. The hypothesis is that teleconference and internet versions of the intervention are non-inferior to the traditional mode of clinical service delivery (ie, one to one, in person) in terms of the primary outcome of self-reported fatigue impact (ie, Fatigue Impact Scale) and the secondary outcome of health-related quality of life (ie, Multiple Sclerosis Impact Scale). Outcomes are being measured at baseline, 2 months, 3 months and 6 months. The primary analysis tool will be linear mixed effects model. The prespecified inferiority margin for the primary outcome is 10 points. We will also examine whether baseline characteristics (eg, sociodemographic) moderate outcomes of the Managing Fatigue intervention and whether changes in self-efficacy and fatigue self-management behaviours mediate changes in outcomes.

ETHICS AND DISSEMINATION

The protocol is approved centrally by the institutional review board at Case Western Reserve University. Eligible participants give consent before being enrolled and randomised into the study. The study results will be disseminated through relevant advocacy organisations, newsletters to participants, publication in peer-reviewed journals and presentations at scientific conferences.

Occupational therapy interventions for multiple sclerosis: A scoping review

BACKGROUND

Evidence for the effectiveness of occupational therapy for people with multiple sclerosis (MS) is yet to be established.

AIMS/OBJECTIVES

To review the evidence regarding the effectiveness of occupational therapy interventions in improving outcomes for adults with MS.

MATERIAL AND METHODS

We completed a scoping review of occupational therapy and multiple sclerosis following a scoping review methodological framework. Search included articles published up until June 2019. Studies were included if they were original research that included adults with MS published in English and assessed interventions delivered by occupational therapists.

RESULTS

The search yielded 1646 results. Following screening and review of articles, thirty papers met the inclusion criteria and were included in the review. Studies were charted and discussed in the areas of: (1) fatigue management or energy conservation; (2) upper-limb rehabilitation; (3) occupation-focussed cognitive rehabilitation; and (4) other types of interventions.

CONCLUSIONS

The quality of evidence that exists for occupational therapy with people with MS is mixed but there are studies that show that occupational therapy can improve occupational and other outcomes in this population.

Significance: Patients have reported many benefits of occupational therapy but the evidence-base to support this needs to be developed.Implications for rehabilitationOccupational therapists are well-placed to intervene with multiple sclerosis symptoms.Evidence for the effectiveness of occupational therapy for people with multiple sclerosis is yet to be established.Fatigue management programmes delivered by occupational therapists are effective in reducing symptoms.Additional training in client-centred practice is no more effective than usual occupational therapy.

Beyond current research practice: Methodological considerations in MS rehabilitation research (is designing the perfect rehabilitation trial the Holy Grail or a Gordian knot?)

Rehabilitation is an essential aspect of symptomatic and supportive treatment for people with multiple sclerosis (MS). The number of randomised controlled trials (RCTs) for rehabilitation interventions in MS has increased over the last two decades. The design, conduct and reporting quality of some of these trials could be improved. There are, however, some specific challenges that researchers face in conducting RCTs of rehabilitation interventions, which are often 'complex interventions'. This paper explores some of the challenges of undertaking robust clinical trials in rehabilitation. We focus on issues related to (1) participant selection and sample size, (2) interventions - the 'dose', content, active ingredients, targeting, fidelity of delivery and treatment adherence, (3) control groups and (4) outcomes - choosing the right type, number, timing of outcomes, and the importance of defining a primary outcome and clinically important difference between groups. We believe that by following internationally accepted RCT guidelines, by developing a critical mass of MS rehabilitation 'trialists' through international collaboration and by continuing to critique, challenge, and develop RCT designs, we can exploit the potential of RCTs to answer important questions related to the effectiveness of rehabilitation interventions.

Beyond supervised therapy: Promoting behavioral changes in people with MS

A critical aspect of many rehabilitation interventions for people with multiple sclerosis (MS) is incorporating strategies that support behavior change. The main purpose of this topical review was to summarize recent randomized clinical trials (RCTs) of rehabilitation interventions in which participants learn and apply skills or engage in healthy behaviors. The Capability, Opportunity, Motivation, and Behavior (COM-B) framework was used to broadly classify behavior-change strategies. The included RCTs varied widely in terms of dosing, delivery format, and types of interventionist. Commonly used behavior-change strategies include education, persuasion, and training. We recommend that researchers and clinicians use frameworks like Behavior Change Wheel and Behavior Change Technique Taxonomy to describe and classify intervention strategies used to promote behavior change. We also recommend more sophisticated RCTs be conducted (e.g. sequential multiple assignment randomized trial and three-arm RCTs) to better understand ways of promoting behavior change in rehabilitation interventions.

Energy management education and occupation-related outcomes in adults with chronic diseases: A scoping review

Introduction

Fatigue is a pervasive symptom of chronic disease that often interferes with occupational performance. Our objective was to describe what is known about energy management education and occupation-related outcomes in adults with chronic diseases.

Methods

Seven electronic databases were searched for relevant literature published before August 2019. Eligible articles were full-text, available in English, and studied energy management education in adults with a chronic disease. The first author assessed article eligibility with validation from a second reviewer, extracted characteristics of included studies, and described them using descriptive statistics. A narrative synthesis of findings was conducted for each chronic disease population.

Results

Forty-four studies addressed eight different chronic disease populations. The most common program delivery format was face-to-face in a group setting (42%), 39% of programs were informed by a learning theory, and their median cumulative length was 8 hours. Positive outcomes were associated with a specific, group-based energy management program in people with multiple sclerosis. The evidence on other energy management programs and in other chronic disease populations was more limited and inconclusive.

Conclusions

Further research is needed to understand the impact of energy management education in chronic disease populations beyond multiple sclerosis, and its impact on occupational performance.

Diurnal Cortisol Secretion Is Not Related to Multiple Sclerosis-Related Fatigue

Some evidence supports the involvement of the hypothalamic–pituitary–adrenal axis (HPA axis) with multiple sclerosis (MS)-related fatigue. In this study, we determined the relation of HPA-axis function with primary fatigue in MS patients in the longitudinal treating fatigue in a MS cohort. MS patients from the TREeating FAtigue in MS (TREFAMS) research program that consists of three randomized controlled trials to study the effects of aerobic training, energy conservation management, and cognitive behavioral therapy on MS-related fatigue were included. The HPA-axis functioning was determined at baseline, the end of treatment (16 weeks) and after 52 weeks. The cortisol awakening response (CAR) and night-time cortisol levels were analyzed. Fatigue was measured with the fatigue subscale of the Checklist Individual Strength (CIS20r fatigue). There was no relationship between CAR and night-time cortisol parameters with CIS20r fatigue scores. Neither of the treatments influenced CAR and night-time cortisol parameters, with the exception of an effect in the energy conservation management treatment group on the CAR surge increase over 52 weeks (β = −114.8, p = 0.007, 95% CI = −197.6, −31.9). Our data suggest that the diurnal cortisol secretion is not associated with MS-related fatigue. This indicates that MS-related fatigue is not attributed to diurnal cortisol secretion and is likely caused by other disease mechanisms.

Testing non-inferiority of blended versus face-to-face cognitive behavioural therapy for severe fatigue in patients with multiple sclerosis and the effectiveness of blended booster sessions aimed at improving long-term outcome following both therapies: study protocol for two observer-blinded randomized clinical trials

BACKGROUND

Cognitive behavioural therapy (CBT) has been found to be effective in reducing fatigue severity in MS patients directly following treatment. However, long-term effects are inconsistent leaving room for improvement. In addition, individual face-to-face CBT draws heavily on limited treatment capacity, and the travel distance to the treatment centre can be burdensome for patients. Therefore, we developed "MS Fit", a blended CBT for MS-related fatigue, based on a face-to-face CBT protocol found effective in a previous study, and "MS Stay Fit", internet-based booster sessions to improve long-term effectiveness of CBT for MS-related fatigue. This article presents the protocol of two randomised clinical trials (RCTs) conducted within one study investigating (1) the non-inferiority of MS Fit compared with evidence-based face-to-face CBT for MS-related fatigue and (2) the effectiveness of MS Stay Fit on the long-term outcome of fatigue compared with no booster sessions.

METHODS/DESIGN

The first part of this study is an observer-blinded non-inferiority multicentre RCT, in which 166 severely fatigued MS patients will be randomly assigned (1:1 ratio, computer-generated sequence) to either face-to-face CBT or blended CBT (MS Fit) for fatigue. The primary endpoint is at 20 weeks after baseline. After this post-treatment assessment, patients will be randomly assigned again (1:1 ratio, computer generated sequence) to either MS Stay Fit consisting of two booster sessions at 2 and 4 months after end of treatment or no booster sessions. The primary endpoint of the second study is 52 weeks after baseline. Primary outcome measure in both studies is fatigue severity assessed with the fatigue severity subscale of the Checklist Individual Strength (CIS20r). Outcomes will be assessed at baseline (T0), at the end of treatment (T20), and after 39 and 52 weeks (T39 and T52).

DISCUSSION

If MS Fit is found to be non-inferior to face-to-face CBT, it will improve the accessibility of this treatment. In addition, the study aims to test whether it is possible to improve long-term effectiveness of CBT for MS-related fatigue with MS Stay Fit.

MS Energize: Field trial of an app for self-management of fatigue for people with multiple sclerosis

Multiple sclerosis (MS) is a lifelong neurological condition affecting around 2.2 million people worldwide. There are a wide range of symptoms, with fatigue reported as one of the most troublesome. MS Energize-or MS Energise in UK English regions-is an iPhone app focused on self-management of fatigue for people with MS. Based on cognitive-behavioral therapy principles, the app covers MS fatigue, how to use energy effectively, how behavior, thoughts and emotions interact and impact on MS fatigue, as well as the potential effects of bodily and environmental factors. MS Energize provides education, interactive tasks, and supports application of the principles into a user's day-to-day life. We field tested the usability and perceived usefulness of MS Energize with 11 people with longstanding multiple sclerosis in New Zealand and the United Kingdom. Participants used the app over a period of five to six weeks after which they rated the usability of the app and participated in an in-depth qualitative interview. We developed four main themes through our thematic analysis. 1. Validation of participants' own experiences of living with MS fatigue. 2. The personal cost in engaging with such an intervention. 3. Reframing experiences and adding to knowledge. 4. That the app was generally a good idea. Field testers' feedback also identified usability issues that could be addressed. In particular, the amount of text-based content in the app contributed to the app itself being fatiguing. This field-testing process has highlighted the value of the app while also guiding our roadmap for further developments to enhance usability and usefulness. The next step is further refinement of components of MS Energize in preparation for a trial of its clinical and cost effectiveness.

Physical activity, sedentary behavior, and restless legs syndrome in persons with multiple sclerosis

The present study examined the relationships among parameters (i.e., volume and pattern) of physical activity and sedentary behavior with the presence and severity of restless legs syndrome(RLS) in adults with multiple sclerosis(MS). Participants with MS (N = 253) wore an accelerometer for a 7-day period and completed the Cambridge-Hopkins Restless Legs Syndrome Questionnaire, the International Restless Legs Syndrome Study Group Scale (IRLS), and the Patient Determined Disease Steps scale. Sixty-six (26%) persons with MS had RLS (MS + RLS). There were no differences between the MS + RLS and MS group for parameters of physical activity or sedentary behavior. Among participants with IRLS scores in the mild range (n = 26), more time spent in light physical activity (r_s = 0.39), fewer sedentary bouts per day (r_s = 0.55), less time in sedentary bouts per day (r_s = 0.51), and fewer breaks in sedentary time per day (r_s = 0.57) were associated with lower RLS severity. This study represents the first step toward recognizing a relationship between physical activity, patterns of sedentary behavior, and RLS severity in MS and these results suggest that light physical activity and the pattern of sedentary behavior may be important targets for prospective behavioral interventions that target the management of RLS in persons with MS who have mild RLS severity.

Self-management program improves participation in patients with neuromuscular disease: A randomized controlled trial

OBJECTIVE

To investigate the effectiveness of Energetic, a self-management group program combining aerobic training, energy conservation management, and relapse prevention to improve social participation in patients with neuromuscular disease (NMD) and chronic fatigue.

METHODS

In this multicenter, assessor-blinded, 2-armed randomized controlled trial with repeated measurements, 53 patients with various types of NMD and chronic fatigue were randomly allocated to Energetic, a 4-month group intervention, or to usual care. The primary endpoint was social participation assessed with the Canadian Occupational Performance Measure (COPM) performance scale immediately postintervention. Secondary outcomes included COPM satisfaction scale, 6-Minute Walk Test (6MWT), and Checklist Individual Strength-subscale fatigue. Participants were followed for 11 months postintervention. Data were analyzed with linear models that account for repeated measurements.

RESULTS

Directly after intervention, the mean group difference for COPM-performance was 1.7 (95% confidence interval [CI] 1.0-2.4; p < 0.0001) in favor of the intervention group (n = 29), adjusted for baseline, sex, diagnosis, and work status. This effect was retained at 11 months follow-up (0.9; 95% CI 0.0-1.7; p = 0.049). The COPM satisfaction scale and 6MWT improved more in the intervention group compared to usual care. After 3 and 11 months follow-up, most beneficial effects on social participation and functional endurance were retained.

CONCLUSION

Energetic led to sustainable improvements in social participation and functional endurance compared to usual care in patients with NMD and chronic fatigue.Clinicaltrials.gov IDENTIFIER: NCT02208687.

CLASSIFICATION OF EVIDENCE

This study provides Class III evidence that a combination of aerobic training, energy conservation management, and relapse prevention improves social participation in patients with NMD and chronic fatigue.

Which behavioural and exercise interventions targeting fatigue show the most promise in multiple sclerosis? A systematic review with narrative synthesis and meta-analysis

Fatigue is a common and highly debilitating symptom of multiple sclerosis (MS). This meta-analytic systematic review with detailed narrative synthesis examined randomised-controlled (RCTs) and controlled trials of behavioural and exercise interventions targeting fatigue in adults with MS to assess which treatments offer the most promise in reducing fatigue severity/impact. Medline, EMBASE and PsycInfo electronic databases, amongst others, were searched through to August 2018. Thirty-four trials (12 exercise, 16 behavioural and 6 combined; n = 2,434 participants) met inclusion criteria. Data from 31 studies (n = 1,991 participants) contributed to the meta-analysis. Risk of bias (using the Cochrane tool) and study quality (GRADE) were assessed. The pooled (SMD) end-of-treatment effects on self-reported fatigue were: exercise interventions (n = 13) -.84 (95% CI -1.20 to -.47); behavioural interventions (n = 16) -.37 (95% CI -.53 to -.22); combined interventions (n = 5) -.16 (95% CI: -.36 to .04). Heterogeneity was high overall. Study quality was very low for exercise interventions and moderate for behavioural and combined interventions. Considering health care professional time, subgroup results suggest web-based cognitive behavioural therapy for fatigue, balance and/or multicomponent exercise interventions may be the cost-efficient therapies. These need testing in large RCTs with long-term follow-up to help define an implementable fatigue management pathway in MS.

Energy Conservation Management for People With Multiple Sclerosis-Related Fatigue: Who Benefits?

OBJECTIVE

We investigated whether demographic, disease-related, or personal baseline determinants can predict a positive response to energy conservation management (ECM).

METHOD

We conducted a secondary analysis of a single-blind, two-parallel-arms randomized controlled trial that included ambulatory adults with severe MS-related fatigue. Therapy responders and nonresponders were categorized by Checklist Individual Strength fatigue change scores between baseline and end of treatment. Logistic regression analyses were used to assess the determinants of response.

RESULTS

Sixty-nine participants were included (ECM group, n = 34; control group, n = 35). In the ECM group, fatigue severity, perception of fatigue, illness cognitions about MS, and social support discrepancies were related to the probability of being a responder.

CONCLUSION

The results suggest that people with MS-related fatigue who had a less negative perception of fatigue and who perceived fewer disease benefits and a higher discrepancy in social support had the best response to ECM treatment.

Prolonged cortical silent period is related to poor fitness and fatigue, but not tumor necrosis factor, in Multiple Sclerosis

OBJECTIVE

Poor fitness among people with Multiple Sclerosis (MS) aggravates disease symptoms. Whether low fitness levels accompany brain functioning changes is unknown.

METHODS

MS patients (n = 82) completed a graded maximal exercise test, blood was drawn, and transcranial magnetic stimulation determined resting and active motor thresholds, motor evoked potential latency, and cortical silent period (CSP).

RESULTS

Sixty-two percent of participants had fitness levels ranked below 10th percentile. Fitness was not associated with disability measured using the Expanded Disability Status Scale (EDSS). Regression analyses revealed that, cardiorespiratory fitness, when controlling for disease demographics, contributed 23.7% (p < 0.001) to the model explaining variance in CSP. Regression analysis using cardiorespiratory fitness and CSP as predictors showed that CSP alone explained 19.9% of variance in subjective fatigue (p = 0.002). Tumor necrosis factor was not associated with any variable.

CONCLUSION

Low fitness was associated with longer CSP in MS. Longer CSP was, in turn, related to greater MS fatigue.

SIGNIFICANCE

MS patients had extremely low levels of cardiorespiratory fitness. Poor fitness predicted longer CSP, a marker of greater intracortical inhibition, which was linked to MS fatigue. Future research should examine whether aerobic training could shorten CSP and potentially lessen inhibition of cortical networks.

Daily Temporal Associations Between Physical Activity and Symptoms in Multiple Sclerosis

Background

Symptom severity is negatively associated with physical activity in multiple sclerosis (MS). However, it is unclear how physical activity and symptoms correlate on a day-to-day basis in persons with MS.

Purpose

To determine the temporal within-person associations of pain, fatigue, depressed mood, and perceived cognitive function with physical activity in MS.

Methods

Ambulatory adults with MS (N = 107) completed 7 days of home monitoring. Continuous physical activity data (assessed via wrist-worn accelerometer) and concurrent ecological momentary assessment (5X/day) of pain, fatigue, depressed mood, and perceived cognitive function were collected. Data were analyzed using multilevel mixed modeling.

Results

Fatigue and depressed mood demonstrated bidirectional associations with physical activity, whereas pain and cognitive function did not. Higher than usual fatigue (B = -5.83, p = .001) and depressed mood (B = -4.12, p = .03) were followed by decreased physical activity. In contrast, higher than usual physical activity was associated with subsequent decline in fatigue (B = -0.001, p = .02) and depressed mood (B = -0.0007, p = .02); however, the association between physical activity and fatigue varied across the day.

Conclusions

Physical activity is dynamically related to fatigue and mood on a moment-to-moment basis in MS. Efforts to increase physical activity in MS must incorporate a focus on how symptoms affect and are affected by activity.

Energy Conservation Management and Physical Behaviour in Fatigued People with Multiple Sclerosis

Main findings Detailed analyses of physical behaviour showed that ambulatory fatigued persons with multiple sclerosis (MS) do differ from healthy controls not only in physical activity level, but also in other physical behaviour dimensions (e.g. day patterns, intensity of activities and distribution of periods of activity). In ambulatory persons with MS-related fatigue, a weak association was found between physical fatigue and several physical behaviour dimensions (i.e., the amount, the intensity and the day pattern of activities). The individual Energy Conservation Management (ECM) format used in this study did not reduce MS-related fatigue and restrictions in participation more than an information-only control condition. Our study does not support the implementation of our individual ECM format as a treatment for MS-related fatigue. Energy conservation strategies given in ECM were appreciated by participants and perceived as useful for fatigue, so ECM seems to have a subjective good effect for fatigued persons with MS. Resulting from a responder study: fatigued people with MS who are more severely fatigued, have a less negative perception of fatigue, perceive fewer disease benefits, and who perceive a higher discrepancy in social support show the best response to ECM treatment.
