Examples of the EMG signals for one representative subject and the comparison of IEMG values. a The EMG signals of one subject during seven experimental tasks. b The comparison of IEMG values between RX task and other tasks. MEH and MEL show significant differences compared to relaxed tasks, while other tasks, motor imagery tasks, show minimal differences
