Fig. 3From: Modifying upper-limb inter-joint coordination in healthy subjects by training with a robotic exoskeletonWAM positions. The eight Experimental Target positions (ET) and the four Generalization Target positions (GT). The asterisks * show the mean position of head and shoulder, and the projection of the starting position of the elbow/end-effector. On the left, x-z frontal plane, on the right, y-z sagittal plane (some targets are coincident on this plane). The frames are consistent with the reference frame of Fig. 1 Back to article page
