Fig. 2From: A brain-computer interface driven by imagining different force loads on a single hand: an online feasibility studyExamples 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 differencesBack to article page
