Remote Exercise Effects on Cognitive Processing Speed in Multiple Sclerosis: A Pilot Trial

"This condition will include 16-weeks of remotely-delivered and supported aerobic walking exercise training based on guidelines for physical activity in persons with MS for general health benefits. Exercise intensities will be prescribed based on steps per exercise sessions from a waist-worn FitBit One™ (FitBit, Inc., San Francisco, CA).~The exercise program involves one-on-one semi-structured sessions with an MS exercise specialist (i.e., behavior coach) throughout the program. These sessions focus on exercise training guidance and oversight, discussion of the behavioral strategies of action planning and self-monitoring, and presentation and discussion of newsletters for optimizing exercise compliance."

The active, non-aerobic exercise condition will involve stretching-and-toning activities. These activities will be based on a manual provided by the National Multiple Sclerosis Society. Participants will be provided with necessary exercise equipment (e.g., yoga mat, FitBit), an instructional DVD, and a manual, log-book, calendar, and prescription for the stretching program. This program will be supplemented with periodic newsletters delivered electronically that highlight principles of behavior change, and video-chats with a behavior coach that provide motivation and social accountability. These occur on the same timeline and frequency as in the walking condition, but focus on constructs for stretching.
