Examining a Wheelchair Exercise-training Intervention for Persons With Multiple Sclerosis

"The proposed exercise training program is based on Social Cognitive Theory (SCT) for promoting aerobic and strength training in wheelchair users with MS. The 16-week program includes one-on-one video chats with a behavioral coach and various tracks for progressive increases in both strength and aerobic training. The proposed strength training includes 15 exercises with step-by-step instructions using resistance bands and/or wrist weights that were adapted for seated body-position that can be executed in a wheelchair. The proposed aerobic training is arm cycle ergometry; this is a low-cost and modifiable option that fits the needs of both power and manual wheelchair users. Other proposed equipment includes a comprehensive Training Manual, fitness tracker for use during exercise training sessions, and Rate of Perceived Exertion (RPE) scale for guiding individualized exercise intensity. The research team created 12 Newsletters that align with 12 proposed coaching calls."

The attention/contact wellness control condition will mirror the exercise training intervention condition, but focuses on implementing health behaviors other than physical activity (e.g., diet and emotional wellbeing). This program is an adapted version of the WellMS program from Prof. Motl's Phase III clinical trial (NCT03490240). The program is based on SCT principles of behavior change and integrates wellness resources from the National MS Society (NMSS). The research team has created 12 Newsletters that will be delivered on the same chat schedule as the exercise training intervention. All coaching chats and newsletters will occur with the same frequency as in the exercise training intervention condition. Participants will be provided with a participant manual, logbook, and calendar. Participants will work with their behavioral coach on goal setting specific to wellness behaviors.
