Static body postural misalignment in individuals with temporomandibular disorders: a systematic review

Abstract

BACKGROUND: The association between body postural changes and temporomandibular disorders (TMD) has been widely discussed in the literature, however, there is little evidence to support this association. OBJECTIVES: The aim of the present study was to conduct a systematic review to assess the evidence concerning the association between static body postural misalignment and TMD. METHOD: A search was conducted in the PubMed/Medline, Embase, Lilacs, Scielo, Cochrane, and Scopus databases including studies published in English between 1950 and March 2012. Cross-sectional, cohort, case control, and survey studies that assessed body posture in TMD patients were selected. Two reviewers performed each step independently. A methodological checklist was used to evaluate the quality of the selected articles. RESULTS: Twenty studies were analyzed for their methodological quality. Only one study was classified as a moderate quality study and two were classified as strong quality studies. Among all studies considered, only 12 included craniocervical postural assessment, 2 included assessment of craniocervical and shoulder postures,, and 6 included global assessment of body posture. CONCLUSION: There is strong evidence of craniocervical postural changes in myogenous TMD, moderate evidence of cervical postural misalignment in arthrogenous TMD, and no evidence of absence of craniocervical postural misalignment in mixed TMD patients or of global body postural misalignment in patients with TMD. It is important to note the poor methodological quality of the studies, particularly those regarding global body postural misalignment in TMD patients.

Severidade da disfunção temporomandibular e sua relação com a postura corporal

“…The severity of TMD is an important finding to evaluate the progression and impact of dysfunction in the life of the affected individuals 15,18 . However, to the best of our knowledge, the design of studies involving TMD and body posture generally only associates postural conditions with the presence of dysfunction [6][7][8]12 and it does not seek to investigate this relationship with TMD severity.…”

“…Milanesi et al 10 observed that the higher the anterior position of the head, the greater the severity of signs and symptoms related to mandibular movements and masticatory muscles. In the review by Chaves et al 7 , of the 20 articles that investigated the craniocervical posture, ten found postural changes of this segment in the TMD group. Among these ten, three found lower anterior head angles related to the presence of TMD.…”

“…Temporomandibular disorder (TMD) is a term used to designate several clinical signs and symptoms affecting the muscles of mastication, the temporomandibular joint (TMJ) and structures associated 1,2 . It is considered as a multifactorial disorder 3,4 , presenting as its etiologic factors joint trauma, occlusal discrepancies, joint hypermobility, skeletal problems, parafunctional habits, and psychosocial and behavioral factors 5 .…”
