ABSTRACT
INTRODUCTION: Multiple Sclerosis (MS) is a neurological disorder with an increasing global prevalence and severe complications. MS14® is a Persian-medicine-derived natural product with herbal and marine origin which has shown beneficial effects in the management of MS complications. In this study, its effect on physical activity of MS patients was investigated. METHODS: A triple-blind placebo-controlled clinical trial was conducted. Participants used either MS14 capsule or placebo 3 times a day for 3 weeks. At baseline and end of the study, physical activity indices were assessed using international physical activity questionnaire (IPAQ). Secondary outcome measures were Fatigue Severity Scale (FSS), timed 10 m walk, Ashworth scale, and Timed Get up and Go. RESULTS: A total number of 80 MS patients completed the study. At the end of study, improvement of general physical activity (p-value=0.047) and Timed 10 m walk index (p-value=0.003) in the MS14 group was significant when compared to placebo. No serious adverse effects were observed in this study. CONCLUSION: Considering the improvement of some physical activity indices, MS14® is seems to be a safe natural product which could be considered as a supplementary treatment in MS patients. Future larger trials are suggested to further evaluate its efficacy.
