The primary aim of this study was to examine familial associations in spinal posture, defined using postural angles and a clinical classification method. A secondary aim was to investigate the reliability of clinical postural classification. Postural angles were calculated from sagittal photographs, while two experienced clinicians made use of standing sagittal images to classify participants into one of four postural groups (sway, flat, hyperlordotic, neutral). Parent-child associations in postural angles and postural groups were evaluated using Pearson's correlation and Fisher's exact test, respectively. Inter-rater reliability was expressed using percentage agreement and Kappa coefficients (K). Daughters whose father or mother had a hyperlordotic posture were 4.0 or 3.5 times, respectively, more likely to have a hyperlordotic posture than daughters whose parents did not have a hyperlordotic posture. These participants in the hyperlorotic group had a significantly higher body mass index than members of the other postural groups (p < 0.03). Percentage agreement between clinicians was 63.5% (K = 0.48). These results provide preliminary evidence of a familial association in the hyperlordotic posture and support the use of postural classification.
本研究的主要目的是使用姿势角度和临床分类方法来检查脊柱姿势的家族关联性。次要目的是调查临床姿势分类的可靠性。姿势角度由矢状面照片计算得出，同时两名经验丰富的临床医生利用站立位矢状面图像将参与者分为四个姿势组之一（摇摆型、扁平型、腰椎前凸过度型、中立型）。姿势角度和姿势组中的亲子关联性分别使用Pearson相关性分析和Fisher精确检验进行评估。评分者间信度用一致率和Kappa系数（K）表示。父亲或母亲有腰椎前凸过度姿势的女儿，分别比父母没有腰椎前凸过度姿势的女儿有4.0倍或3.5倍的可能性出现腰椎前凸过度姿势。这些腰椎前凸过度组的参与者的体重指数显著高于其他姿势组的成员（p < 0.03）。临床医生之间的一致率为63.5%（K = 0.48）。这些结果为腰椎前凸过度姿势的家族关联性提供了初步证据，并支持姿势分类的应用。
