Altered Corticomuscular Coherence (CMCoh) Pattern in the Upper Limb During Finger Movements After Stroke

Background: Proximal compensation to the distal movements is commonly observed in the upper extremity (UE) in patients with chronic stroke. However, the cortical origin of this compensation has not been well understood. In this study, corticomuscular coherence (CMCoh) and electromyography (EMG) analysis were adopted to investigate corticomuscular coordinating mechanism of post-stroke compensatory activities of proximal UE in distal motions of...
