    ObjectiveTo compare patients with chronic migraine (CM) and chronic temporomandibular disorders (TMD) on disability, pain, and fear avoidance factors and to associate these variables within groups.DesignDescriptive, cross-sectional study.SettingsA neurology department and a temporomandibular disorders consult in a tertiary care center.SubjectsA total of 50 patients with CM and 51 patients with chronic TMD, classified by international criteria classifications.MethodsThe variables evaluated included pain intensity (visual analog scale [VAS]), neck disability (NDI), craniofacial pain and disability (CF-PDI), headache impact (HIT-6), pain catastrophizing (PCS), and kinesiophobia (TSK-11).ResultsStatistically significant differences were found between the CM group and the chronic TMD group in CF-PDI (P < 0.001), PCS (P = 0.03), and HIT-6 (P < 0.001); however, there were no differences between the CM group and the VAS, NDI, and TSK-11 groups (P > 0.05). For the chronic TMD group, the combination of NDI and TSK-11 was a significant covariate model of CF-PDI (adjusted R2 = 0.34). In the CM group, the regression model showed that NDI was a significant predictive factor for HIT-6 (adjusted R2 = 0.19).ConclusionsDifferences between the CM group and the chronic TMD group were found in craniofacial pain and disability, pain catastrophizing, and headache impact, but they were similar for pain intensity, neck disability, and kinesiophobia. Neck disability and kinesiophobia were covariates of craniofacial pain and disability (34% of variance) for chronic TMD. In the CM group, neck disability was a predictive factor for headache impact (19.3% of variance).© 2017 American Academy of Pain Medicine. All rights reserved.
