Mult Scler Relat Disord 2024; 90:105827. [PMID: 39213861 DOI: 10.1016/j.msard.2024.105827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2024] [Revised: 06/09/2024] [Accepted: 08/16/2024] [Indexed: 09/04/2024]
Abstract
BACKGROUND For persons with multiple sclerosis (pwMS), exercise is known to be safe and effective at treating several symptoms and it may even be disease-modifying. However, exercise can trigger heat intolerance, exercise-induced heat sensitivity (EIHS), which may cause some pwMS to refrain from exercise. No review has yet summarized the existing knowledge on EIHS in pwMS. Therefore, the purpose of the present review was to clarify the terminology, summarize both the prevalence of EIHS and the current knowledge of underlying mechanisms, and provide an overview of existing treatment options and clinical management of EIHS in pwMS. METHODS A scoping review was performed. RESULTS As no clear definition could be identified in the literature, we propose a definition of EIHS. Aspects related to EIHS are reported in 29-80 % of all pwMS. The mechanisms underlying EIHS are not well understood but seem to include axon demyelination, CNS lesions, abnormal sudomotor function and sweating, abnormal afferent thermosensory function, disease stability, and abnormal neuropsychological responses. The severity of EIHS depends on the applied exercise modality, intensity, and format, and can be further reduced when applying different cooling interventions or garments before and/or during exercise. CONCLUSION EIHS appears frequently in pwMS, but the underlying mechanisms are still only sparsely understood. EIHS severity depends on exercise-related factors and can be reduced by cooling interventions.

Abstract
Treatment fidelity is a key component for assessing the reliability and validity of clinical trials in behavioral medicine. This manuscript reports on the outcomes of a pre-planned fidelity monitoring protocol for a Phase-III clinical trial, project Behavioral Intervention for Physical Activity in Multiple Sclerosis (BIPAMS). The fidelity monitoring protocol included the five areas of the National Institutes of Health Behavior Change Consortium with primary data sources including: coaching call checklists, coaching logs, auditing of coaching calls by experts, behavioral resource bank within the treatment group, review of participant website log-ins, review of participant self-monitoring, and team meetings for discussing participant progress and protocol adherence. The fidelity monitoring protocol was implemented across six waves of participants, and a final sample of 269 participants (i.e., n = 135 in BIPAMS intervention and n = 134 in WellMS control) completed the 24-week study. Ten coaches were comprehensively trained to implement the study protocol, which included an orientation call and one-on-one behavioral coaching calls. Among BIPAMS participants, an average of 11.81/13 scheduled calls were completed, and 96 (62% of planned) were audited by an expert. Among WellMS participants, an average of 8.19/9 calls were completed, and 54 (55% of planned) audits were completed. Unplanned protocol deviations included inability to complete live call audits during the COVID-19 pandemic lockdown and changes in coaching criteria to accommodate unanticipated medical conditions and graduations. This manuscript provides an example and insights for demystifying treatment fidelity monitoring to help facilitate wide-spread use of standard protocols.

Abstract
BACKGROUND We propose a randomized controlled trial(RCT) of a Social Cognitive Theory-based(SCT), Internet-delivered behavioral intervention targeting lifestyle physical activity(LPA) for yielding improvements in cognitive processing speed(CPS), learning and memory(L/M), symptoms, and quality of life(QOL) among persons with mild multiple sclerosis(MS)-related ambulatory impairment who have impaired CPS. METHODS/DESIGN The study involves a Phase-II, parallel group, RCT design. Participants with MS(N = 300) will be randomly assigned on an equal basis(1:1) into behavioral intervention(n = 150) or attention and social contact control(n = 150) conditions. The conditions will be administered over 6-months by trained behavior coaches who will be uninvolved in screening, recruitment, random assignment, and outcome assessment. We will collect outcome data remotely every 6-months over the 12-month period(baseline, immediate follow-up, and 6-month follow-up) using a treatment blinded assessor. The primary outcome is the raw, oral Symbol Digit Modalities Test as a neuropsychological measure of CPS. The secondary outcomes include the California Verbal Learning Test-II as an objective measure of L/M, and patient-reported outcomes of fatigue, depressive symptoms, anxiety, pain, and QOL. The tertiary outcome is accelerometry as an objective, device-based measure of steps/day for generating a minimal clinically important difference(MCID) value that guides the prescription of LPA for improving CPS in clinical practice. The primary data analyses will involve intent-to-treat principles, and mixed-effects models and logistic regression. DISCUSSION If successful, the proposed study will provide Class I evidence for the efficacy of a theory-based, Internet-delivered behavioral intervention focusing on LPA for improving CPS and mitigating its negative impact on other outcomes in persons with MS.

Abstract
BACKGROUND We reported that a social cognitive theory-based (SCT), Internet-delivered behavioral intervention increased device-measured minutes/day of moderate-to-vigorous physical activity (MVPA) over a 6-month period among persons with multiple sclerosis (MS). This paper examined the pattern and predictors of heterogeneity in change for MVPA. Based on previous research, we hypothesized that mild MS disability, fewer MS symptoms, lower baseline MVPA, and positive SCT characteristics (e.g., high exercise self-efficacy) would be associated with greater change in MVPA. METHOD Persons with MS (N = 318) were randomized into behavioral intervention (n = 159) or attention/social contact control (n = 159) conditions that were administered via Internet websites and supported with behavioral coaching. Demographic, clinical, symptom, behavioral, and SCT data were from before the 6-month period of delivering the conditions, and MVPA data were from before and after the 6-month period. We examined heterogeneity based on waterfall plots, box plots, and the Levene statistic. We identified predictors of MVPA change using bivariate correlation and multiple, linear regression analyses per condition. RESULTS The Levene statistic indicated statistically significant heterogeneity of variances for MVPA change between conditions (p = .003), and the waterfall plots and box plots indicated greater heterogeneity in MVPA change for the behavioral intervention. MVPA change score was correlated with baseline MVPA (r = - .33 and r = - .34, p = .0004 and p = .0001) in both conditions and walking impairment (r = - .188, p = .047) and race (r = .233, p = .014) in the behavioral intervention condition. The regression analysis indicated that baseline MVPA (Standardized B = - .449, p = .000002), self-reported walking impairment (Standardized B = - .310, p = .0008), and race (Standardized B = .215, p = .012) explained 25.6% of variance in MVPA change for the behavioral intervention condition. CONCLUSION We provide evidence for walking impairment, baseline MVPA, and race as predictors of the heterogeneity in the pattern of MVPA change with a behavioral intervention.

Feasibility of a new intervention addressing group-based balance and high-intensity training, physical activity, and employment in individuals with multiple sclerosis: a pilot randomized controlled trial. FRONTIERS IN REHABILITATION SCIENCES 2024; 4:1258737. [PMID: 38259873 PMCID: PMC10801079 DOI: 10.3389/fresc.2023.1258737] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 07/14/2023] [Accepted: 12/08/2023] [Indexed: 01/24/2024]
Abstract
Background and purpose Impaired sensorimotor function, reduced physical activity and unemployment are common challenges in persons with multiple sclerosis (pwMS), even when disability is low. CoreDISTparticipation is a new, multidisciplinary intervention delivered across healthcare levels systematically addressing these elements. This study primarily aimed to evaluate the feasibility of CoreDISTparticipation in terms of process, resources, management, and scientific outcomes. The secondary aim was to evaluate initial efficacy in terms of possible short-term effects compared with the usual care on barriers to employment, balance, walking, health-related quality of life (HRQoL), and physical activity. Methods This assessor-blinded prospective pilot randomized controlled trial included 29 pwMS [Expanded Disability Status Scale (EDSS): 0-3.5] randomly allocated to the intervention group (CoreDISTparticipation) (n = 15) or usual care (n = 14). CoreDISTparticipation consists of three phases: (1) hospital outpatient clinic: MS nurse work-focused session and physiotherapist exploring balance; (2) municipality: a digital meeting with pwMS, employer, MS nurse, and physiotherapist addressing employment and physical activity, 4 weeks indoor CoreDIST balance training (60 min × 2/week); and (3) 4 weeks outdoor CoreDIST balance training and high-intensity running/walking (60 min × 2/week). Assessments were undertaken at baseline and at weeks 6 and 11. Primary feasibility metric outcomes were the reporting of process, resources, management, and scientific outcomes. Efficacy measures included evaluation of the Multiple Sclerosis Work Difficulties Questionnaire-23 Norwegian Version (MSWDQ-23NV) and 6 Minute Walk-test as well as the Trunk Impairment Scale-modified Norwegian Version, Mini-Balance Evaluation Systems Test (Mini-BESTest), Multiple Sclerosis Walking Scale-12, Multiple Sclerosis Impact Scale-29 Norwegian Version (MSIS-29NV), ActiGraph wGT3x-BT monitors, and AccuGait Optimized force platform. The statistical analyses included repeated-measures mixed models performed in IBM SPSS Version 29. Results The primary feasibility metric outcomes demonstrated the need for minor adjustments in regard to the content of the intervention and increasing the number of staff. In regard to the efficacy measures, one person attended no postintervention assessments and was excluded, leaving 28 participants (mean EDSS: 1.8, SD: 1). The mean percentage employment was 46.3 (SD: 35.6) and 65.4 (SD: 39.3) in the CoreDISTparticipation and usual care group, respectively. No between-group differences were found. MSWDQ-23NV demonstrated a within-group difference of 5.7 points from baseline to Week 11 (P = 0.004; confidence interval: 2.2-9.3). Mini-BESTest and MSIS-29NV demonstrated within-group differences. The study is registered in ClinicalTrials.gov (Identifier: NCT05057338). Discussion The CoreDISTparticipation intervention is feasible to support pwMS when the identified feasibility metric outcomes in regard to process, resource, management, and scientific outcome metrics are adjusted to improve feasibility. Regarding efficacy measures, no between-group differences were detected; however, within-group differences in barriers to employment, balance, and HRQoL were detected for the CoreDISTparticipation group. A larger comparative trial is needed to explore between-group differences and should accurately and precisely define usual care and address the identified limitations of this study.

Abstract
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.

Abstract
Background Reduced physical activity is a worldwide challenge in individuals with multiple sclerosis (MS). The aim of this systematic review and meta-analysis was to identify devise-measured effects of physical activity, exercise and physiotherapy-interventions on step count and intensity level of physical activity in individuals with MS. Methods A systematic search of the databases of PubMed (including Medline), Scopus, CINHAL and Web of Science was carried out to retrieve studies published in the English language from the inception to the first of May 2023. All trials concerning the effectiveness of different types of exercise on step count and intensity level in people with MS were included. The quality of the included studies and their risk of bias were critically appraised using The modified consolidated standards of reporting trials and the Cochrane Risk of Bias tool, respectively. The pooled standardized mean difference (SMD) and 95% CI of the step-count outcome and moderate to vigorous intensity level before versus after treatment were estimated in both Intervention and Control groups using the random effect model. The Harbord test were used to account for heterogeneity between studies and assess publication bias, respectively. Further sensitivity analysis helped with the verification of the reliability and stability of our review results. Results A total of 8 randomized clinical trials (involving 919 individuals with MS) were included. The participants (including 715 (77.8%) female and 204 (22.2%) male) had been randomly assigned to the Intervention (n = 493) or Control group (n = 426). The pooled mean (95% CI) age and BMI of participants were 49.4 years (95% CI: 47.4, 51.4 years) and 27.7 kg/m2 (95% CI: 26.4, 29 kg/m2), respectively. In terms of the comparison within the Intervention and the Control groups before and after the intervention, the results of the meta-analysis indicate that the pooled standardized mean difference (SMD) for step-count in the Intervention group was 0.56 (95% CI: -0.42, 1.54), while in the Control group it was 0.12 (95% CI: -0.05, 0.28). Furthermore, there was no significant difference in the pooled SMD of step-count in the physical activity Intervention group compared to the Controls after the intervention (pooled standard mean difference = 0.19, 95% CI: -0.36,0.74). Subgroup analysis on moderate to vigorous intensity level of physical activity revealed no significant effect of the physical activity intervention in the Intervention group compared to the Control group after the intervention, or within groups before and after the intervention. Results of meta regression showed that age, BMI, duration of disease and Expanded Disability Status Scale (EDSS) score were not the potential sources of heterogeneity (all p > 0.05). Data on the potential harms of the interventions were limited. Conclusion The results of this meta-analysis showed no significant differences in step count and moderate to vigorous physical activity level among individuals with MS, both within and between groups receiving physical activity interventions. More studies that objectively measure physical activity are needed. Systematic Review Registration https://www.crd.york.ac.uk/prospero/, identifier: CRD42022343621.
