Reliability and responsiveness of elbow trajectory tracking in chronic poststroke hemiparesis
This study established the reliability of a novel upper-limb trajectory-tracking task for assessment of perceptual motor control in hemiparetic adults. Eleven persons with chronic poststroke hemiparesis (mean 58.6 months) and eleven nondisabled control subjects performed an elbow flexion-extension task against a low-resistance isotonic load at three speeds: 25degrees/s, 45degrees/s, and 65degrees/
