  1. Percentiles of the ratios between the jaw jerk amplitude in the intercuspal position (ipJJ%) and the bR-MEPs, indicating the asymmetry value. One asterisk (*) denotes the reference value for the maximum limit of asymmetry for trigeminal responses of the bR-MEPs % (cutoff a) for healthy subjects. Two asterisks (**) denote the maximum limit of asymmetry for the jaw jerk (cutoffb), corresponding to 75% of the TMD group (***).
