FRP onset determination on the EMG rectified signal of one channel of the HDEMG grid. The red horizontal line represents the three standard deviations of mean of baseline EMG activity measured during quiet standing. The red vertical line (B) denotes the FRP onset in relation to the start (A) and the end (B) of the truck flexion determined by the electrogoniometer.
