Fig. 7From: Modifying upper-limb inter-joint coordination in healthy subjects by training with a robotic exoskeletonMean motion duration T (a), mean peak velocity v max (b), and mean smoothness η (c). Averaged data over the ten participants and standard error for the pointing tasks towards ET positions for the two different modes. Smoothness, through spectral arc-length, is higher when η is closer to zeroBack to article page
