Mapping Corticoreticulospinal Motor Control in Chronic Hemiparetic Stroke

Recruiting now · Not applicable

Conditions studied: Stroke, Hemiparesis

In brief

This study uses functional magnetic resonance imaging to map neural activity throughout the central nervous system during a shoulder abduction task to characterize what motor pathways are being used post-stroke.
