Multiple Sclerosis Clinical Trial

WEBCAMS: Walking Exercise for Brain and Cognition in Adults With Multiple Sclerosis

Summary

This study is a randomized controlled trial (RCT) that compares the effects of two different 12-month aerobic walking exercise programs on cognitive processing speed (CPS), brain MRI, and other functional outcomes in 32 adults with multiple sclerosis (MS) who are able to walk without an assistive device but demonstrate slowed CPS. Participants (N=32) will initially undergo screening via telephone, and after satisfying relevant inclusion/exclusion criteria, will provide informed consent, followed by a baseline assessment of CPS remotely via a HIPAA-compliant virtual platform (i.e., Zoom for Healthcare). This assessment will also serve as a screen for ensuring impaired CPS. Following this virtual session, participants will come into Kessler Foundation (KF) and complete a 3-hour baseline assessment (T0) that includes a relatively short battery of neuropsychological tests, a 40-minute MRI scan, tests of walking function, a short questionnaire packet, followed by cardiopulmonary exercise testing on a motor-driven treadmill. Following T0, participants will be randomly assigned into one of the two aerobic walking ET programs that are remotely-delivered and supported by KF research assistants. As the conditions are delivered and supported remotely by KF personnel, the exercise itself takes place in the home/community setting. Both conditions involve behavior coaching via Zoom for Healthcare. The experimental condition involves high-frequency, high-intensity aerobic walking ET that exceeds the published guidelines for physical activity for adults with MS (GEMS+). GEMS + initially involves 10 minutes of moderate intensity aerobic walking exercise for 3 days per week and progresses to upwards of 40 minutes of vigorous intensity aerobic walking exercise for 5 days per week by month 12. The comparison condition involves mild-to-moderate aerobic walking exercise training that approximates published guidelines (GEMS). GEMS initially involves 10 minutes of light intensity aerobic walking exercise for 2 days per week and progresses up to 30 minutes of moderate intensity aerobic walking exercise for 3 days per week. Both conditions further will be monitored based on Fitbit-measured steps per exercise session. Of note, the sample size will be enrolled using 2 overlapping waves (Wave 1 = 14 participants, Wave 2 = 18 participants), 3 months apart. Participants will return to KF at the mid-point (i.e., T6) and end-point (i.e., T12) of the 12-month intervention period to complete the same assessments as T0. The T6 and T12 outcomes will be administered by treatment-blinded research assistants.
