Compensatory motor control after stroke: an alternative joint strategy for object-dependent shaping of hand posture.

Abstract

Efficient grasping requires planned and accurate coordination of finger movements to approximate the shape of an object before contact. In healthy subjects, hand shaping is known to occur early in reach under predominantly feedforward control. In patients with hemiparesis after stroke, execution of coordinated digit motion during grasping is impaired as a… (More)
