RESUMEN
Abstract Aim: This review aimed to provide evidence and highlight the importance of including physical activity (PA) and/or exercise training (ET) as part of the comprehensive multiple sclerosis (MS) care. Methods: Using the current literature on the subject, we provide a brief overview of MS incorporating its definition, common symptoms, prevalence, and potential disease consequences. We further succinctly describe MS as the first line of treatment, as well as the role of PA and ET in the disease. We end the commentary highlighting important recommendations from an international initiative to improve MS-related physical activity research that we believe will help not only improve the area of study but also best practices within this population. Results: There is compelling evidence for the beneficial effects of PA and/or ET on MS-related symptoms and consequently health and quality of life. There is preliminary evidence suggesting the potential for a disease-modifying effect. Conclusion: Fomenting this discussion is timely due to the increased prevalence of MS in different regions of the globe, and people with MS report low levels of PA participation and high amounts of sedentary time. The consequences of inactivity in this population can be drastic. The current body of evidence supports the notion that PA and ET are safe health behaviors that should be adopted as an adjuvant treatment option within the comprehensive and complex MS care due to its benefits on a variety of disease-related symptoms and its potential for improving health and quality of life in this population.
