Method: Methods:, In this controlled clinical study, the sample was composed by individuals presenting EM according to International Classification for Headache Disorders-2. The Research Diagnostic Criteria for TMD was applied to identify painful TMD and a visual analogic scale (VAS) to measure the severity of pain related to TMD. The presence of CA during migraine attacks were assessed using the Allodynia Symptom Checklist (ASC-12). The ASC-12 is a validated questionnaire that measures presence and severity of CA overall and its subtypes [Thermal (T-CA), Static Mechanical (SM-CA), and Dynamic Mechanical (DM-CA)] during headaches. The presence of extra-cephalic body pain (BP) were assessed by the own patient’s drawing, and grouped in 1, 2 and >3 areas of BP.
Result: Results:, Sample was composed by 54 individuals with episodic migraine (EM). Of them, 42 (77.8%) had painful TMD. CA occurred in 16.7% of those without painful TMD (reference group) and in 64.3% among painful TMD group (p=0.028). Individuals with painful TMD presented more severe CA associated with migraine attacks. Positive association was seen between TMD pain intensity assessed by VAS and the severity of CA (p=0.04). TMD was also associated with extra-cephalic painful conditions (p=0.003). With regard the allodynia subtypes, individuals with TMD presented higher CA scores (overall and for all subtypes) then no TMD group.
Conclusion: Conclusion:, TMD are associated with cutaneous allodynia in individuals with EM.
