Experiences and perceived outcomes of persons with multiple sclerosis from participating in a randomized controlled trial testing implementation of the Canadian Physical Activity Guidelines for Adults with MS: an embedded qualitative study

Purpose To describe the experiences and outcomes of participants who enrolled in a randomized controlled trial testing implementation of the Canadian Physical Activity Guidelines for Adults with Multiple Sclerosis. Materials and methods Fifty-six persons with MS who enrolled in the trial participated in the current study which involved a semi-structured interview at 16-week follow-up. Interview data were analyzed using thematic analysis. Results Of the 56 participants, 26 ended up enrolling in a community-based exercise program specialized for persons with multiple sclerosis (MS), 7 joined another gym, 4 trained at home, and 17 took part in no specific program. Across all study participants, positive outcomes were reported across a number of domains including mental function, knowledge about the physical activity (PA) and MS, physical function, advocacy of PA to peers, daily participation, and body awareness. For those who enrolled in the community-based program, having a supportive and inclusive environment was critical to their PA experiences. Furthermore, environmental supports, particularly knowledgeable and supportive trainers and similar peers, contributed largely to the positive mental changes and increased knowledge gained. Conclusions Our study provides support for the promotion of PA in persons with MS and the development of community-based programs adapted for people with MS.
