Effects of High-intensity Gait Training on Fatigue, Gait, and Neuroplasticity in People With Multiple Sclerosis
Trial Parameters
Brief Summary
Nearly 1 million individuals in the United States have multiple sclerosis, which causes fatigue and problems with walking. Fatigue and walking problems are poorly treated, but exercise training, particularly high-intensity walking exercise, may help. This provide insight into whether high-intensity walking exercise can improve fatigue and walking problems in people with multiple sclerosis, which could improve quality of life and reduce economic burden.
Eligibility Criteria
Inclusion Criteria: * Age ≥21 years * Multiple sclerosis diagnosis * Stable disease-modifying therapy (DMT) over the past 6 months * Walking dysfunction (i.e., abnormal gait pattern, Expanded Disability Status Scale (EDSS) score of 4-6.5, and/or Patient-determined disease steps (PDDS) score of 3-6) * Able to walk for 6 minutes at self-paced speed. Handheld assistive device is acceptable. * Symptomatic fatigue (Fatigue Severity Score ≥ 4) Exclusion Criteria: * Adults unable to consent * Pregnant women * Prisoners * Multiple sclerosis relapse within the last 30 days * Other neurological disorders besides multiple sclerosis * Cardiorespiratory or metabolic diseases (e.g., cardiac arrhythmia, uncontrolled hypertension or diabetes, chronic emphysema) * Significant cognitive or communication impairment (Mini-Mental State Examination (MMSE)\<21), which could impede the understanding of the purpose of procedures of the study or prevent the patient from performing the ankle-tracking task. * Sev
