Postural assessment through photography is a simple method that allows the acquisition of quantitative values to define the alignment of body segments. The purpose of this study was to quantitatively assess the postural alignment of several body segments in standing through anterior, posterior, and lateral views.
In this cross-sectional study, 122 subjects were initially evaluated. Seven subjects were excluded from the study after cluster analysis. The final sample had 115 subjects, 75% women with a mean age of 26 ± 7 years. Photographs were taken from anterior, posterior, and lateral views after placement of markers on specific anatomical points. Photographs were analyzed using free Postural Analysis Software/Software of Postural Analysis (PAS/SAPO). Quantitative values for postural analysis variables were ascertained for head, upper and lower limbs, and trunk, along with the frequency of inclinations to the left and to the right.
Regarding the head, 88% of the sample presented some inclination, 67% of which was to the right. There was a predominance of right inclination of the shoulder and pelvis in 68% and 43% of study subjects, respectively. Lower limbs presented mean alignment of 178° in the anterior view, and the trunk showed predominant right inclination in 66% of participants.
Small asymmetries were observed in anterior and posterior views. This study suggests that there is no symmetry in postural alignment and that small asymmetries represent the normative standard for posture in standing.
通过摄影进行姿势评估是一种简单的方法，可获取定量值以确定身体各节段的排列情况。本研究的目的是通过前视图、后视图和侧视图对站立时几个身体节段的姿势排列进行定量评估。
在这项横断面研究中，最初评估了122名受试者。经过聚类分析后，7名受试者被排除在研究之外。最终样本有115名受试者，75%为女性，平均年龄为26±7岁。在特定解剖点放置标记后，从前视图、后视图和侧视图拍摄照片。使用免费的姿势分析软件/姿势分析软件（PAS/SAPO）对照片进行分析。确定了头部、上肢和下肢以及躯干的姿势分析变量的定量值，以及向左和向右倾斜的频率。
关于头部，88%的样本存在某种倾斜，其中67%向右倾斜。分别有68%和43%的研究对象肩部和骨盆向右倾斜占优势。在前视图中，下肢的平均排列角度为178°，66%的参与者躯干向右倾斜占优势。
在前视图和后视图中观察到小的不对称。本研究表明，姿势排列不存在对称性，小的不对称代表站立姿势的规范标准。
