Fig. 2From: Modifying upper-limb inter-joint coordination in healthy subjects by training with a robotic exoskeletonExample of path-constrained tracking task (PCT). The four pictures show the motion from the starting position to the WAM button, while performing PCT exercise. The participants were asked to follow the specific endpoint path shown by the rubber band going from the starting position of the ABLE exoskeleton to the WAM end-effectorBack to article page
