Physical Activity and Pediatric Multiple Sclerosis
Children with multiple sclerosis (MS) who exercise regularly may have a less active disease.

To evaluate the association between physical activity (PA) and multiple sclerosis (MS) disease activity, depression, and fatigue in a cohort of children with MS and monophasic acquired demyelinating syndrome (mono-ADS).
A total of 110 patients (79 mono-ADS; 31 MS; 5–18 years; M:F 1:1.2) were included. Patients with MS reported less strenuous (33.21 ± 31.88 metabolic equivalents [METs] vs 15.97 ± 22.73 METs, p = 0.002) and total (44.48 ± 39.35 METs vs 67.28 ± 59.65 METs; p = 0.0291) PA than those with mono-ADS. Patients with MS who reported greater amounts of moderate PA METs had fewer sleep/rest fatigue symptoms (r = −0.4). Participation in strenuous PA was associated with smaller T2 lesion volumes (r = −0.66) and lower annualized relapse rate (r = −0.66). No associations were found between total brain volume and participation in PA.
