Fig. 7From: A new approach of inducing proprioceptive illusion by transcutaneous electrical stimulationData processing and analysis representation. The graphical representation of the exemplary temporal change of the left elbow joint angle, during the arm matching task with right elbow joint at reference angle of 90°. Horizontal dashed line in graph represents the average of the baseline measures of the left elbow angle, which was used as a reference to evaluate the extent of proprioceptive illusion. Bottom window, magnified from the first waveform, shows how we minimized potential errors during the transition phase in calculation of the elbow joint angleBack to article page
