Figure 2.

Averaged movement kinematics of a representative subject. The thick lines show means during the resistive (red) and assistive (black) conditions; the shaded areas outline SD across 25 trials without TMS. The vertical gray lines indicate times of TMS across multiple trials; zero is the moment of exiting the T0 target. A, Angular position of shoulder and elbow joints. B, Angular velocity of shoulder and elbow joints. C, Angular acceleration of shoulder and elbow joints. All values are in the local joint-based reference frames.
