Error Enhancement of the Velocity Component

The purpose of this pilot study was to explore the impact of enhancement of the velocity component error in the course of reaching movements of the impaired/hemiparetic limb in an acute stroke subject. We hypothesized that the method would shift velocity profiles toward the optimal, resulting in a reduction in error. A prototype robot. This robotic device system has a two-dimensional motor, basic measurement capacities, and a robotic arm which is engaged to the subject's upper-limb in a sitting position. The enhancement of the velocity component error would shift velocity profiles toward the optimal, resulting in a reduction in error.
