目的：定量描述舒适直立站立时头和肩的姿势排列以及胸椎的表面弯曲，并检查年龄和性别对头和肩排列的影响。设计：描述性调查。设置：步态研究实验室。参与者：160名年龄在17岁至83岁之间的无症状志愿者。主要结果测量：在冠状面和矢状面拍摄了5张头部和肩部姿势的照片，在矢状面拍摄了1张胸椎表面曲率的照片。冠状头倾斜角、冠状肩角、矢状头倾斜角、矢状C7-耳屏角和矢状肩-C7角的平均值分别为180.1度、181度、分别为172.1度、131.1度和53.7度。平均值的95%置信区间范围为1度至3.8度。对于每个头部和肩部测量值，没有显著的性别差异（p = 0.33至0.99）。五个测量，只有矢状面C7-耳屏角与年龄（r = 0.44）显着相关，没有与表面曲率的胸椎。结论：头和肩的姿势是相似的性别之间。只有一个姿势的描述，已被描述的轶事被确定，即，年龄与位置的头部相对于躯干在矢状面，虽然强度的关联是值得怀疑的临床意义。相反，其他长期存在的假设不被支持，因此，前向头与胸椎弯曲或上颈椎伸展增加无关。(C)1997年由美国康复医学大会和美国物理医学和康复学会。
Objective: To quantitatively describe the postural alignment of the head and shoulders and the surface curvature of the thoracic spine in comfortable erect standing and to examine the effect of age and gender on head and shoulder alignment.Design: Descriptive survey.Setting: Gait research laboratory.Participants: One hundred sixty asymptomatic volunteers aged between 17 and 83 years.Main Outcome Measures: Five photographic measurements of head and shoulder posture in the coronal and sagittal planes and a photographic measurement of the surface curvature of the thoracic spine in the sagittal plane.Results: Mean values of coronal head tilt, coronal shoulder angle, sagittal head tilt, sagittal C7-tragus angle, and sagittal shoulder-C7 angle were 180.1 degrees, 181 degrees, 172.1 degrees, 131.1 degrees, and 53.7 degrees, respectively. The 95% confidence intervals for the means ranged between 1 degrees and 3.8 degrees. For each of the head and shoulder measurements there was no significant gender difference (p = .33 to .99). Of the five measurements, only sagittal C7-tragus angle was significantly correlated with age (r = .44), and none was correlated with surface curvature of the thoracic spine.Conclusions: Head and shoulder posture was similar between genders. Only one postural description that has been described anecdotally was identified, ie, that age was related to the position of the head with respect to the trunk in the sagittal plane, although the strength of the association was of questionable clinical significance. In contrast, other longstanding assumptions were not supported, and accordingly, a forward head was not associated with increased thoracic curvature or upper cervical spine extension.
