Evaluation of an Online, On Demand Multimodal Wellness Program to Reduce Fatigue and Improve Quality of Life in Progressive Multiple Sclerosis. (DEW)

Detailed Description Multiple sclerosis (MS) is a chronic neurodegenerative disease that affects nearly one million individuals in the United States. Progressive forms of the disease, including Primary Progressive Multiple Sclerosis (PPMS) and Secondary Progressive Multiple Sclerosis (SPMS), account for approximately 400,000 cases and are associated with substantial disability, fatigue, reduced quality of life, impaired mobility, mood disturbances, and cognitive challenges. Existing disease-modifying therapies have demonstrated effectiveness in reducing inflammatory disease activity but have limited impact on common disabling symptoms such as fatigue, anxiety, depression, and reduced health-related quality of life. Observational studies and preliminary intervention trials suggest that lifestyle factors, particularly diet quality, physical activity, and stress management practices, may improve symptoms and quality of life in people living with MS. However, high-quality randomized controlled trials evaluating integrated multimodal wellness interventions in individuals with progressive MS remain limited. This gap is particularly important because individuals with PPMS and SPMS often face barriers to in-person rehabilitation and wellness programs due to mobility limitations, transportation challenges, bowel and bladder dysfunction, and residence in rural communities. The purpose of the Evaluation of an Online, On demand Multimodal Wellness Program to Reduce Fatigue and Improve Quality of Life in Progressive Multiple Sclerosis: A Randomized Waitlist controlled Trial (DEW Study) is to evaluate the effectiveness of a fully online, on-demand multimodal wellness intervention designed to reduce fatigue and improve quality of life among adults with progressive multiple sclerosis with significant fatigue disability. The intervention combines dietary education, structured exercise programming, stress management training, and behavioral support delivered through accessible virtual platforms. The DEW intervention consists of three primary components:1. Creating Health Online Wellness Course Delivered through the University of Iowa Canvas platform. Provides education regarding a modified Paleolithic dietary approach, with a Mediterranean dietary pathway available as an alternative. Emphasizes increased intake of nutrient-dense foods, including vegetables, and reduction of ultra-processed foods Includes practical resources related to meal planning, cooking skills, behavior change, and self-management strategies. 2. MS Gym Online Exercise Program A commercially available exercise platform specifically designed for individuals with multiple sclerosis. Provides mobility-level specific aerobic, resistance, balance, and functional movement exercises. Includes adaptations for seated and standing participation to accommodate varying levels of disability. 3. Stress Management Training. Participants are instructed in the 4-7-8 breathing technique, a structured breathing exercise intended to reduce stress and anxiety while supporting relaxation and sleep quality. Participants randomized to the intervention arm will also have access to monthly virtual group support sessions conducted via Zoom and facilitated by study personnel. These sessions utilize behavioral support and motivational interviewing principles to enhance adherence and self-efficacy. Participants may additionally communicate with the research team by email or text messaging for support throughout the intervention period. This study employs a randomized, waitlist-controlled design. Following informed consent, participants complete a 7-day run-in period designed to assess their ability to complete study procedures and baseline questionnaires. Participants who successfully complete baseline assessments will be randomized in a 1:1 ratio to either the intervention arm or a waitlist-control arm. Randomization is stratified by baseline fatigue severity. Participants assigned to the waitlist-control group will continue their usual diet, medical care, and lifestyle practices throughout the initial study period. They will receive general wellness information and monthly educational communications but will not have access to the wellness intervention during the primary comparison period. Following completion of the study assessments, waitlist participants will receive access to the Creating Health wellness course, the MS Gym exercise program, and a coaching session. Assessments are conducted electronically at baseline, Month 3, and Month 6 using validated patient-reported outcome measures. The primary outcome is change in fatigue severity, assessed using the Fatigue Severity Scale (FSS) at Month 3. Secondary outcomes include fatigue impact, health-related quality of life, mood, physical activity, dietary adherence, self-efficacy, social support, and participant acceptability of the intervention. Measures include the Modified Fatigue Impact Scale (MFIS), Multiple Sclerosis Quality of Life-54 (MSQOL-54), Hospital Anxiety and Depression Scale (HADS), Godin Leisure Time Exercise Questionnaire (GLTEQ), Physical Activity Vital Signs (PAVS), Mediterranean Diet Adherence Screener (MEDAS-14), Paleolithic Diet Adherence Screener (PDAS-12), Multiple Sclerosis Self-Efficacy Scale (MSSE), Multidimensional Scale of Perceived Social Support (MSPSS), Theoretical Framework of Acceptability questionnaire, and a Process Evaluation Questionnaire. The primary hypothesis is that participants receiving the DEW intervention will demonstrate greater improvements in fatigue at 3 months compared with participants receiving usual care. Secondary hypotheses are that intervention participants will experience improvements in quality of life, mood, physical activity, dietary adherence, self-efficacy, and perceived social support. Process evaluation measures will be used to identify barriers and facilitators to implementation and inform future dissemination of the intervention. By evaluating a scalable, fully virtual wellness program targeting fatigue and quality of life in progressive MS, this trial seeks to establish an accessible, non-pharmacologic approach that may help address important unmet needs among individuals living with progressive forms of multiple sclerosis.
