The subjective fatigue was assessed in Borg’s RPE, the pain intensity (=peak pain) in numeric rating scale (NRS), the pain area in arbitrary units (au), the change in pressure pain threshold in percent (%), the change in maximum voluntary bite force in percent (%) and the change in maximum mouth opening capacity in percent (%). Data are expressed as median (IQR; interquartile range). P-values refer to the comparisons between sessions by Mann-Whitney Rank Sum test. * = significant difference P < 0.005 for subjective fatigue and pain intensity, < 0.013 for pain area and < 0.006 for the rest of the variables after applied Bonferroni Corrections
