Changes in maximum output range of cyclic movement ±1 standard deviation averaged across all trials for (a) the PG/PS adaptive and (b) the open-loop control system during a 500-cycle movement from an intermittent training paradigm. The intermittent movement trial consists of 100 sets of stimulation of five movement cycles (4.8 s stimulation) interspersed with 20 s of rest (500 cycles, 8 min stimulation in total). The horizontal axis shows only the successive stimulating cycle number and the output range is given as a percent of the maximum range of the desired movement pattern.
