  NS SS
  1. Percentage value of the bR-MEPs% and of the jaw jerk for the TMD and control groups when the mandible is kept in intercuspal position (ipJJ%). Since the P-value, for the bR-MEPs% is not less than 0.05 we cannot reject the null hypothesis while the P-value for ipJJ% is less than 0.05 the null hypothesis is rejected and is statistically significant (SS)
