Catastrophizing Has a Better Prediction for TMD Than Other Psychometric and Experimental Pain Variables

Table 1

Experimental induced sensitivity or pain thresholds and scores for disability when living with pain and psychometric variables in TMD patients compared to healthy controls.

Measure	Controls		Patients		value
	Mean (SD)	Median	Mean (SD)	Median
PPT finger	553 (235.6)	516.05	402 (178.1)	375.3	0.001
PPT masseter	246 (106.3)	211.72	168 (81.4)	167.7	0.001
PPT TMJ	225 (112.9)	202.20	157 (69.6)	156.3	0.003
EPT finger	12.94 (6.29)	11.50	11.10 (6.27)	10	0.014
EST finger	4.66 (1.42)	4.00	4.36 (1.15)	4.00	0.185
RMS	0.86 (2.15)	0.00	7.25 (4.11)	7.00	0.001
HADS anxiety	3.22 (2.98)	2.00	7.12 (4.83)	6.00	0.001
HADS depression	1.36 (1.99)	1.00	5.83 (4.67)	5.00	0.001
Catastrophizing	1.33 (2.44)	2.44	7.16 (2.47)	8.00	0.001

Notes: the Wilcoxon signed-rank test was used for group comparison. Abbreviations: PPT = pressure pain threshold; TMJ = temporomandibular joint; EPT = electrical pain threshold; EST = electrical sensibility threshold; RMS = Roland Morris Disability Questionnaire (0–24p); HADS = Hospital Anxiety and Depressions Scale. Units: PPT = kPa; EPT/EST = 0–99; RMS = 0–24p; HADS anxiety = 0–21p; HADS depression = 0–21p; catastrophizing = 0–12p. These results have been published before by Staniszewski et al. in 2018.
