Headache attributed to temporomandibular disorders and masticatory myofascial pain

Abstract

We investigated the temporal association between temporomandibular disorders (TMD)-related symptoms and headache during TMD treatment for patients who fulfilled the diagnostic criteria for headache attributed to TMD (HATMD) specified in the Diagnostic criteria for TMD (DC/TMD) and International classification of headache disorders (ICHD)-3 beta. The study enrolled 34 patients with HATMD induced by masticatory myofascial pain but not by temporomandibular arthralgia. Facial pain intensity, the pressure pain threshold of pericranial muscles, and maximum unassisted opening of the jaw were assessed at an initial examination and before and after physical therapy. The intensity and frequency of headache episodes and tooth contact ratio were also recorded before and after the intervention. Headache intensity and frequency significantly decreased, and these reductions were temporally related to improvements in facial pain intensity, maximum unassisted opening, and pressure pain threshold during TMD treatment. Linear regression analysis showed significant correlations between facial pain intensity and headache intensity and between tooth contact ratio and pressure pain threshold. Among patients who fulfilled the DC/TMD and ICHD-3 beta diagnostic criteria for HATMD, headache improved during TMD treatment, and the improvement was temporally related to amelioration of TMD symptoms. These findings suggest that sensitization in the central and peripheral nervous systems is responsible for HATMD. (J Oral Sci 58, 195-204, 2016).

Headache attributed to TMD Is Associated With the Presence of Comorbid Bodily Pain: A Case‐Control Study

“…TMDH has been listed as 1 of 12 most common types of TMD, with prevalence ranging between 1 and 5.7% . Recent studies suggest that TMDH is amenable to the management of TMD . Patients with TMDH exhibited a significantly increased pressure pain threshold (PPT) in the temporalis muscles, while TMD patients without TMDH had a significantly increased PPT in the masseter muscles .…”

Change in muscle hardness after trigger point injection and physiotherapy for myofascial pain syndrome

“…In the SM group, patients were instructed to follow a home exercise program that included stretching and massaging of their masseter, temporal, sternocleidomastoid, and trapezius muscles, according to the procedure detailed at the first visit (7). Briefly, they were instructed to use their bilateral hypothenars to massage the symptomatic temporal and/or masseter muscles at the tender point for 30 s each.…”

“…MPS is easily misdiagnosed, which can lead to mistreatment (1)(2)(3)(4). Although various methods have been used to assess masticatory MPS and its treatment-such as visual analog scale (VAS) score, pressure pain threshold, maximum mouth opening, tooth contact ratio, magnetic resonance elastography, ultrasound imaging, and Doppler flow waveform-evaluation is not standardized and remains controversial (5)(6)(7).…”
