Background: Persons with multiple sclerosis (PwMS) report difficulties with emotion regulation and empathy. Regular physical activity (RPA) improves dimensions of psychological well-being in PwMS, but it remains unclear if regular physical activity has effects on emotion regulation and empathy. The present study investigated the effect of regular physical activity on emotion regulation and empathy, and explored, if endurance training or coordinative training are better than an active control condition.

Methods: 92 female PwMS (mean age: 37.4 years; age range: 20-57 years; mean EDSS: 2.43) took part in this study. Participants were randomly assigned into endurance training, coordinative training, or active control conditions that all lasted 8 weeks and were yoked on frequency, duration, and social contact. Participants completed questionnaires on emotion regulation, empathy, depression and fatigue before and after the 8-week conditions.

Results: Regulation and control of emotions and empathy improved over time, but more so in the exercising groups, compared to the active control group. No changes over time and between groups were observed for perception and acknowledgement of emotions, emotional expressivity, and empathy, as measured with Reading in the Eyes test. These changes were not influenced by control for depression and fatigue as covariates.

Conclusions: Both endurance and coordinative exercise training had favorable effects on some aspects of emotion regulation and social cognition such as empathy in PwMS. Such initial results support for examination of exercise training for the treatment of issues of emotion regulation and social interactions in PwMS.
