| Abstract: | [Purpose] This study aimed to investigate the characteristics of upper quadrant postureof young women with temporomandibular disorders. [Subjects] The participants were 19female patients with temporomandibular disorders (patient group: mean age, 30.1 years) and14 controls (control group: mean age, 24.6 years). [Methods] Outcome measures were theneck inclination angle (formed by a line connecting C7 and the ear tragus with ahorizontal line), the angle of the shoulder (formed by a line connecting C7 and theacromial angle with a horizontal line), the cranial rotation angle (formed by a lineconnecting the ear tragus and the corner of the eye with a horizontal line), and theneck-length/shoulder-width ratio [the ratio of the neck length (from C7 to the tragus) tothe width of the shoulder between the acromial angle]. The maximum range of mouth openingwas measured using a scale. [Results] The neck inclination angle and maximum range ofmouth opening were significantly smaller in the patient group than in the control group.No significant differences were observed in the other outcome measures between the twogroups. [Conclusion] Temporomandibular disorders with limited mouth opening in youngfemales are associated with the head position relative to the trunk.Key words: Posture, Temporomandibular disorders, Ultrasound-based three-dimensional motion analyser |
