Fig. 1From: Somatosensory profiles of patients with chronic myogenic temporomandibular disorders in relation to their painDETECT scorea 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)Back to article page
