a Increase of pressure pain from unpleasant over painful to trigger point on masseter muscle palpation in patients with TMD (TMD all, n = 19; TMD subgroups concerning their painDETECT score (≤ 12, n = 12; 13–18, n = 3; ≥ 19, n = 4); mean ± SD (masseter left + right); b QST-pressure pain threshold (PPT) presented as z-score values (mean value of patients (masseter left + right) - mean controls (masseter left + right)/SD controls). A z-score of 0 means the score is the same as for the mean of healthy subjects. It can also be negative or positive indicating a loss or gain of function; p-value for TMD all as results of unpaired t-test as related to healthy subjects considering the Levene’s test for equality of variances; p-value according to the painDETECT scores as results of analysis of variance (ANOVA) with LSD post hoc correction of multiple comparison; (n.s. = not significant, * = p < 0.05, ** = p < 0.01, *** = p < 0.001)
