Abstract

There is no clear evidence on how a headache attributed to temporomandibular disorder (TMD) can hinder the improvement of facial pain and masticatory muscle pain. The aim of this study was to measure the impact of a TMD-attributed headache on masticatory myofascial (MMF) pain management. The sample was comprised of adults with MMF pain measured according to the revised research diagnostic criteria for temporomandibular disorders (RDC/TMD) and additionally diagnosed with (Group 1, n = 17) or without (Group 2, n = 20) a TMD-attributed headache. Both groups received instructions on how to implement behavioural changes and use a stabilisation appliance for 5 months. The reported facial pain intensity (visual analogue scale - VAS) and pressure pain threshold (PPT - kgf cm(-2)) of the anterior temporalis, masseter and right forearm were measured at three assessment time points. Two-way anova was applied to the data, considering a 5% significance level. All groups had a reduction in their reported facial pain intensity (P < 0001). Mean and standard deviation (SD) PPT values, from 133 (054) to 196 (106) kgf cm(-2) for the anterior temporalis in Group 1 (P = 0016), and from 127 (035) to 172 (060) kgf cm(-2) for the masseter in Group 2 (P = 0013), had significant improvement considering baseline versus the 5th-month assessment. However, no differences between the groups were found (P > 0100). A TMD-attributed headache in patients with MMF pain does not negatively impact pain management, but does change the pattern for muscle pain improvement. (AU)
