through bodily re-explorations and interactions with the surroundings: a qualitative study on changed perceptions of physical activity in people with mild multiple sclerosis.

Introduction: Reduced physical activity (PA) among people with multiple sclerosis (pwMS) with low disability is a significant concern. Developing healthcare to promote PA requires a comprehensive understanding of pwMS's perspectives.

Purpose: To explore how pwMS with mild disability perceive PA and the impact of individual, professional, social, and environmental aspects on their PA engagement.

Methods: Qualitative, in-depth interviews with 27 pwMS (21 women, 6 men; aged 31-66; EDSS ≤ 3.5) were analyzed via systematic text condensation and informed by enactive theory.

Results: Three categories were formed: : Participants adapted their perceptions to PA throughout their disease journey. Initial uncertainty concerning bodily capacities, prospects and safety reduced PA. Moving "correctly" during activities was emphasized to facilitate PA levels. : Pleasure associated with movement was a highlighted motivator, however, some experienced PA less rewarding after diagnosis. Discomfort and fear were barriers to PA engagement. : Participants sought social interactions and outdoor-environments to improve PA. Healthcare professionals were trusted to provide possibilities for PA, but early-stage and tailored follow-up was often lacking.

Conclusion: This study illuminates changed PA perceptions after MS diagnosis and how affect, shaped by personal, interpersonal, and environmental aspects, drive PA engagement. Moreover, it calls for early follow-up and the implementation of tailored healthcare throughout the disease course to promote PA engagement. Considering these findings, we have put forth a model aimed at fostering a nuanced comprehension of PA in pwMS with mild disabilities. Further development and exploration of this model is needed.
