Evaluation of head posture in patients with temporomandibular joint disorders: a cross-sectional study.

OBJECTIVE

This study evaluated head posture in patients with temporomandibular joint disorders and explored the effects of postural changes on clinical parameters.

METHODS

In total, 81 individuals diagnosed with temporomandibular joint disorders participated in this cross-sectional prospective study. Demographics, pain status, head posture, and jaw movement data were collected. Head posture was assessed using the Posture Screen Mobile application.

RESULTS

Results indicated moderate negative correlations between pain and mouth opening (rho=-0.437, p<0.001) and maximum mouth opening (rho=-0.427, p<0.001). Anterior translation showed weak positive correlations with mouth opening and maximum mouth opening, while right lateral translation exhibited a weak positive correlation with pain (rho=0.264, p=0.017). Posterior angulation showed weak significant correlations with pain, mouth opening, and maximum mouth opening.

CONCLUSION

These findings suggest that head posture has a significant influence on temporomandibular joint disorder symptoms. Treatment strategies addressing postural abnormalities may help alleviate symptoms and enhance the quality of life in temporomandibular joint disorder patients.
