From: Proportional estimation of finger movements from high-density surface electromyography
Representative results from one subject during online target task. The figure illustrates the quality of proportional tracking during the online test when using the three methods (CSP-PE, LDA and THR). The task for the subject was to activate the fingers, one at a time, tracking a reference trapezoidal trajectory. a The continuous colored and gray lines are the estimated and reference trajectories for each finger, including both silent (zero level) and active phases (trapezoids). b Active phases concatenated, with the indicated nMSE of estimation. With THR, false activations were more frequent and the ring extension could not be properly estimated
