摘要

The purpose of this study was to investigate coremuscle characteristics during walking in patients with multiplesclerosis (MS). Eight patients (4 men) with relapsingremittingMS (aged 44.9 +/– 8.6 yr) and sexmatched controls (37.9 +/–8.4 yr) walked on a treadmill for 15 min at a selfselected speed.Positron emission tomography/computed tomography imagingwas used to measure core muscle activity immediately afterwalking based on glucose uptake. Activity was not differentbetween the MS and control group for any of the identified muscles(p > 0.28). Within the MS group, side differences in activitywere identified in the lateral flexor group, the external and internalobliques, and the rectus abdominis (p < 0.05), with the lessaffectedside being activated more. Furthermore, greater musclevolume was found on the moreaffected side of the transversusabdominis, quadratus lumborum, and the lowback extensorgroup (p < 0.03). These muscle characteristics suggest patientswith MS utilize compensatory mechanisms during walking tomaintain balance and posture. These strategies likely result inincreased muscle energy cost and early fatigability.
