A Qualitative Study of Exercise and Physical Activity in Adolescents with Pediatric-Onset Multiple Sclerosis

Pediatric-onset multiple sclerosis (POMS) accounts for up to 5% of all multiple sclerosis (MS) cases. Of note, the existing literature regarding physical activity and POMS is sparse, and there is limited insight about the lived experiences of individuals with POMS regarding physical activity, including perceptions of its benefits, barriers, facilitators, and promotion.

We conducted a qualitative exploration of physical activity perceptions and experiences and of preferences for a physical activity intervention in eight persons with POMS. Using semistructured interviews and interpretative phenomenological analysis, we crafted numerous themes that provide new knowledge of physical activity experiences and preferences in this population.

The adolescent participants believed that physical activity would be beneficial and important but further believed that it can often be boring and may worsen POMS symptoms. Participants described adequate symptom management, social support, time, and opportunity as facilitators of physical activity, and lack of social support, time, and opportunity as hindrances. The interviewees described that components of a future intervention should focus on education regarding specific exercises, outcomes, and safety during exercise and provide opportunities for social engagement with other individuals with POMS.

This qualitative study provides novel findings regarding the perceptions and experiences of physical activity in POMS. An important step in crafting an understanding of physical activity behavior in POMS, this study serves to inform the development and delivery of physical activity behavioral interventions.
