Multiple sclerosis (MS) is a leading cause of disability in young adults, with symptoms varying based on lesion size, location, and disease course. These symptoms often worsen over time, significantly impacting quality of life. To manage symptoms and potentially affect disease activity, patients are often directed to exercise interventions, though the impact on disease progression is still being studied. Neuroimaging, particularly magnetic resonance imaging (MRI), is commonly used to monitor MS, but MRI does not reveal brain activation levels, which is why functional MRI is recommended for a more detailed evaluation. Exercise, both face-to-face and telerehabilitation (TR), is considered an effective treatment for MS. Studies show that TR increases patient adherence and can be as effective as in-person therapy. Our study aims to assess the effects of a multimodal exercise program combining face-to-face and TR on disease activity and functional status in patients with MS (PwMS). PwMS with an Expanded Disability Status Scale (EDSS) score of 3.0 to 5.5 will be randomly assigned to either the multimodal exercise training group (Group I) or a control group (Group II). Disease activity, disability, aerobic capacity, physical activity, balance, fatigue, and quality of life will be evaluated. Group I will participate in exercise training three days a week (one day in-person, two days TR) for 12 weeks. Group II will receive no exercise during this period and will be reassessed after 12 weeks.
