Post-hoc analysis for RF H-reflex magnitude extraction. We modified a previously used method to estimate the H-reflex [24, 25]. EMG response with maximum M-wave (EMGMmax, black) and the current EMG response (EMGcurr, dark blue) with M-wave and H-wave regions (a). An exponential fit (efit, gray) beginning at the peak (Mpeak) of the EMGcurr were subtracted from EMGcurr instead of the previously introduced procedure [24] using hindmost flank of the EMGMmax to reduce selection variability indicated by the light blue region (b). The estimated H-wave (Hest) and the variability of the estimated H-waves resulted from hindmost flank selection (Hvar, light blue area, c)
