Figure 1.
RMS determination from raw EMG signal. Only 10 burst of about 60 burst/increment duration is given. A) Raw EMG bursts. B) Calculated RMS envelope from raw EMG signal. C) The calculated RMS envelope was averaged and 25%, 35% and 45% of the average value is used as a threshold. In the figure 1C, horizontal line represents the 25% level.
