This study aimed to determine if temporomandibular disorders (TMD) correlate with alterations in body posture detectable through posturography.
Thirty-five asymptomatic subjects and 35 TMD patients (34 males and 36 females; mean age, 27.7+/-8.6 years) constituted the matched control and TMD groups, respectively. Posturography was performed under four different experimental conditions: (a) eyes open with mandibular rest position (Eyes Open RP); (b) eyes open with dental occlusion (Eyes Open DO); (c) eyes closed with mandibular rest position (Eyes Closed RP); and (d) eyes closed with dental occlusion (Eyes Closed DO). The X, Y, and absolute centre of pressure displacements from the projection of a theoretical barycentre and the sway area, sway length, and sway velocity were recorded as static and dynamic posturographic parameters, respectively.
Generally, no differences were found in any of these parameters between the groups and between the RP and DO within either Eyes Open/Closed conditions. The only differences were found under Eyes Closed as compared to Eyes Open, irrespective of the RP/DO conditions for dynamic and not for static posturographic parameters.
This study failed to show detectable alterations in body posture in TMD patients.
本研究旨在确定颞下颌关节紊乱症（TMD）是否与通过姿势描记法可检测到的身体姿势改变相关。
35名无症状受试者和35名TMD患者（34名男性和36名女性；平均年龄27.7±8.6岁）分别构成匹配的对照组和TMD组。在四种不同的实验条件下进行姿势描记法：（a）睁眼，下颌处于休息位（睁眼休息位）；（b）睁眼，牙齿咬合（睁眼咬合位）；（c）闭眼，下颌处于休息位（闭眼休息位）；（d）闭眼，牙齿咬合（闭眼咬合位）。分别记录从理论重心投影的X、Y和绝对压力中心位移以及摆动面积、摆动长度和摆动速度作为静态和动态姿势描记参数。
一般来说，在睁眼/闭眼条件下，两组之间以及休息位和咬合位之间在这些参数中的任何一个上均未发现差异。唯一的差异是在闭眼与睁眼相比时发现的，无论动态姿势描记参数还是静态姿势描记参数，均与休息位/咬合位条件无关。
本研究未能显示TMD患者身体姿势有可检测到的改变。
