Mapping Corticoreticulospinal Motor Control in Chronic Hemiparetic Stroke

Description

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.

Conditions

Stroke, Hemiparesis
