Widespread mechanical pain hypersensitivity in patients with chronic migraine and temporomandibular disorders: relationship and correlation between psychological and sensorimotor variables

Abstract

Objective: This study aimed to assess mechanical hyperalgesia in the trigeminal and extra-trigeminal regions in patients with chronic migraine (CM) and temporomandibular disorders (TMD) in comparison to asymptomatic subjects and to determine the association between sensorimotor variables and psychological and disability variables and evaluate the prediction of a sensorimotor variables though psychological and disability variables in patients with CM and TMD. Material and methods: A total of 52 subjects with concomitant CM and TMD and 30 asymptomatic subjects were included in the study. The pressure pain threshold (PPT), maximal mouth opening (MMO) and a series of self-reported factors were compared. Results: There were 52 CM and TMD (92.3% women and 7.7% men; age ¼ 46.2 ± 9.5) and 30 asymptomatic subjects (80% women and 20% men; age ¼ 47.4 ± 10). Differences were found between patients with CM and TMD and asymptomatic participants (p < .01) when comparing the PPTs in the trigeminal and extra-trigeminal regions. The PPT for the trigeminal region was predicted by depressive symptoms (variance of 18%) as well as disability and craniofacial pain (variance of 20%). The extratrigeminal region PPT was predicted by depressive symptoms (variance of 10%), and pain-free MMO was predicted by disability and craniofacial pain (variance of 24%). Conclusions: This study suggests that patients with CM and TMD present with generalized mechanical hyperalgesia. In addition, an association between sensorimotor, psychological and disability variables was observed.

Assessment and Brain Training of Patients Experiencing Head and Facial Pain with a Distortion of Orofacial Somatorepresentation: A Narrative Review

“…The onset and persistence of head and face pain can be related to an impairment in the reception and processing of the nociceptive stimuli and the central nervous system (CNS) [22,23]. During long-term peripheral facial nociception, such as TMD pain, odontalgia and post-face-trauma changes of brainstem and CNS circuits emerge, which may lead to altered facial pain [24].…”

Has the Phase of the Menstrual Cycle Been Considered in Studies Investigating Pressure Pain Sensitivity in Migraine and Tension-Type Headache: A Scoping Review

“…After reading full-text of the remaining 27 studies, another nine were excluded because: results were not divided into TTH or migraine [ 31 , 32 , 34 ], text did not include the required data [ 68 ], it was an experimental-induced pain model [ 36 ], results were not separated by gender [ 69 , 70 ], PPT was not assessed with algometer or dynamometer [ 43 ], or due to the absence of IHS criteria [ 71 ]. Finally, 18 studies satisfied all inclusion criteria and were included in the review of migraine ( Figure 2 ) [ 7 , 12 , 13 , 14 , 15 , 52 , 55 , 60 , 63 , 66 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 ].…”

“…The recruitment process of the patients with migraine was done from tertiary hospitals [ 14 , 15 , 72 ], outpatient clinics [ 52 , 73 ], hospitals [ 75 , 77 ], pain clinics [ 79 ], advertisements at universities or local newspapers [ 63 , 74 , 78 , 79 ], university centres of ageing [ 63 ], random sample population [ 55 , 66 ], and social media such as Facebook [ 78 , 79 ].…”

“…Several studies excluded patients who had taken medication, such as analgesics or muscle relaxants, 24–48 h before examination [ 7 , 12 , 13 , 14 , 15 , 52 , 60 , 72 , 73 , 74 , 75 , 77 , 78 , 79 ], except for four in which this consideration was not taken into account [ 55 , 63 , 66 , 76 ]. Garrigós-Pedrón et al [ 77 ] permitted the use of abortive pharmacological treatment during the assessment.…”

Terapia de fotobiomodulação na disfunção temporomandibular: Resultados preliminares em dor e movimentos mandibulares

“…A avaliação do LDP foi realizada apenas na região orofacial. Alguns trabalhos recomendam a utilização de pontos supostamente neutros como controle da flutuação do LDP em regiões que não passaram por intervenção terapêutica (Magri et al, 2017;Garrigós-Pedrón et al, 2019). Entretanto, pacientes com DTM, frequentemente apresentam comorbidades com outras áreas de dor corporal, como cervicalgias e fibromialgia (Aaron;Buchwald, 2003 (Fernández-de-las-Peñas et al, 2010a).…”
