Fig. 3From: Controlling a motorized orthosis to follow elbow volitional movement: tests with individuals with pathological tremorVoluntary motion related measures. a Voluntary component power changes for the MO (PCvMO) and the TSO (PCvTSO). The horizontal dashed line indicates zero value. b Position pursuit tracking RMSE for the fMO (epfMO) and TSO (epTSO). c Velocity pursuit tracking RMSE for the fMO (evfMO) and TSO (evTSO). d Voluntary interaction torque (same as Fe in Fig. 4) root mean square for the TSO. The scatter plots are composed of four unique markers associated with the four motion cases of the pursuit tracking experiment, namely sine slow (ss), sine fast (sf), random slow (rs) and random fast (rf)Back to article page
