3. Fig 2
The elbow angle, angular velocity, angular acceleration, and jerk (the 3rd derivatives of the angle) between the unaffected arm (right column), and the affected arm (left column) of a subject after stroke during voluntary elbow tracking at the peak velocity of 62.8°/s. The dotted line is from the target angle, and the solid lines are calculated on the basis of actual elbow trajectories.

Comparison of RMSE between the unaffected arm (Δ) and the affected (▿) arm at 6 velocities (15.7°, 31.4°, 47.1°, 62.8°, 78.5°, and 94.2°/s) during elbow tracking movement. Vertical bars indicate the SD. *P<.05.
