Potential of M-Wave Elicited by Double Pulse for Muscle Fatigue Evaluation in Intermittent Muscle Activation by Functional Electrical Stimulation for Motor Rehabilitation

Figure 6

Examples of measured M-waves elicited by the 4th and the double pulse (a) and the calculated M-wave elicited by the 2nd pulse of the double pulse (b) in the same burst duration. The beginnings of M-waves were made to match by the beginning time of the stimulation pulse. Stimulation artifacts in the recorded EMG signals are seen in (a) and those of the 2nd stimulation pulse have been removed in (b).
