This study examined the correlation between the forward head posture (FHP), temporomandibular joint disorder (TMD), and temporomandibular joint quantitative somatosensory sensation. This study examined the correlation between the temporomandibular joint function and somatosensory sensation according to the change in FHP after the intervention on the head posture in 62 subjects (22.15 ± 2.56 years) Biofeedback training was administered to the FHP, which was performed 12 times for a total of four weeks. To assess the FHP, the craneovertebral angle (CVA) was examined. The temporomandibular joint (TMJ) function was measured by the Therapeutic Range of Motion Scale and the left and right lateral deviation, and the sensation of vibration threshold was measured to confirm the change in somatic sensation. Multiple regression analysis was performed to confirm the influence of each variable and Pearson's correlation analysis was performed to assess the correlation. Changes in the temporal joint function (p<.001) and somatic sensation (p<.001) were correlated significantly with the changes in CVA. These results show that there is a significant correlation between the frontal head position, TMJ function, and somatosensory sensation. These results provide a new paradigm for the treatment of jaw joints for patients suffering from TMD and provide a basis for the future treatment of the temporomandibular joint.
