颞下颌关节紊乱病患者与健康人头前伸姿势的对照分析

目的:探讨颞下颌关节紊乱病（temporomandibular disorders,TMD）患者和健康人之间头前伸角度的差异。方法:从康复医学科门诊选取TMD患者91例（男18例,女73例）;同时招募健康受试者83例（男20例,女63例）。从左侧拍摄受试者坐位矢状面照片,包括头颈和上胸段。记录头颈角,即耳屏和C7棘突连线和水平线形成的夹角。采用SPSS 20.0软件包分析不同性别TMD患者和健康人头颈角之间的差异。结果:无论是男性还是女性,TMD患者的头颈角度均显著小于健康组（P<0.01）。结论:相比健康人群,TMD患者头部明显过度前伸,头颈姿势异常。

Control study of forward head posture between patients with temporomandibular disorders and healthy people

PURPOSE: To investigate the difference of forward head posture between patients with temporomandibular disorders(TMD) and healthy people. METHODS: Ninety-one TMD patients (18 males and 73 females) were recruited from the Department of Rehabilitation; Meanwhile, eighty-three healthy participants（20 males and 63 females）were recruited. A digital camera was used to capture images of the sagittal plane of the head and neck and upper thorax. The craniovertebral angle between the horizontal line passing through C7 and a line extending from the tragus of the ear to C7 was recorded. The difference of craniovertebral angle between TMD patients and healthy people of different genders were analyzed with SPSS 20.0 software package. RESULTS: In both male and female groups,the craniovertebral angle of TMD patients was significantly smaller than that of healthy people（P<0.01）. CONCLUSIONS: Compared with healthy people, TMD patients present more forward head with abnormal head and neck posture.
