Summary of online cursor control performance with optimal force and adaptive EMG decoders. (a) The cursor trajectories during BC conditions (middle and rightmost panels) were more jagged than during HC (leftmost panel). (b) Most performance metrics were comparable for the adaptive EMG (blue bars) and the optimal force (red bars) decoders, but neither was as good as during HC (grey bars). Error bars represent 2*SEM. (c) The main reason for these differences appeared to be related to the greater cursor jitter present in the optimal force decoder predictions, observable as increased power in the higher frequencies. Note that the 2Hz periodic fluctuations in the force power spectra during both BC conditions are an artifact of using a 500ms decoder window length.
