Multiple Sclerosis (MS) is a chronic neurological disease that places a high burden on patients, families and society. Physical activity in MS is associated with improved fitness, symptoms, and function, fewer relapses, and fewer brain lesions on MRI. Saskatchewan has one of the highest rates of MS worldwide, and a recent survey estimated approximately 80% of persons living with MS are not sufficiently active for health benefits. Individuals living with MS recognize the importance of physical activity, but often indicate a lack support, including limited access to professionals knowledgeable about both MS and physical activity. There is a need to identify effective interventions for improving activity levels safely and appropriately. Behaviour change strategies target specific behaviours involved in increasing and maintaining physical activity. The primary objective of this project is to determine if individualized behaviour change strategies delivered by neurophysiotherapists increases physical activity in MS. Participants will be randomly assigned into two groups. The intervention group will receive individualized behaviour change strategies delivered through the support of neurophysiotherapists for 12 months. The wait-list control group will receive usual care for 12 months, and then be offered the intervention for a 6-month period at the end of the study period. The long-term goal of this research is to help decrease the burden of MS by identifying new opportunities for increasing physical activity.
