Fig. 1From: Sensory gating and suppression of subjective peripheral sensations during voluntary muscle contractiona A typical example of an induced electromyogram waveform from a single participant in both conditions (for 10 stimulations). The waveforms of both conditions are M-waves on the left side and F-waves on the right side of the central thick line. The display range of the F-wave is 10 × that of the M-wave. The changes in average F-wave appearance rate (b), latency (c), and amplitude (d) of all participants in both conditions are displayed. *P < 0.05Back to article page
