Symmetry is one of the criteria of correct body posture in upright position. The spatial positioning of the pelvic girdle is crucial to it. Functional and structural asymmetries within the lumbo-pelvic-hip complex can have a significant influence on the structure and functions of many human body organs and systems. The aim of the study was to present the results of inclinometer measurements of selected landmarks of the pelvic girdle in young adults aged 19-29.
The analysis of occurrence of spatial pelvic asymmetry was based on the authors' original, clinical classification and the significance of the body mass and height for the analyzed asymmetries. The inclinometer measurements of the selected landmarks of the pelvic girdle were performed in a sample consisting of 300 young individuals. Then, the occurrences of the spatial asymmetry of the pelvis were analyzed based on the authors' own clinical classification using alignment symmetry of the iliac crests, the anterior superior iliac spines and the trochanters major as a criterion. All study subjects with asymmetry <1 degree were treated as those with a symmetrical pelvis.
The significance of gender, body mass and height for the analyzed asymmetries was assessed. Symmetric positioning of the iliac crests was observed in only 32% of the respondents. The iliac crest depression on the left side was more frequently observed - in 41% of the respondents. This occurred more often in women (44%) than in men (38%). In the group of women, the rotated pelvis was the most often observed (39.4%) asymmetry, while for men, it was the oblique pelvis (40%). More detailed analysis by pelvic asymmetry subtypes showed their statistical differentiation between women and men ( < 0.0001). Analysis of moderate rotation of the pelvis for men, were reported slightly higher values but these differences were not statistically significant ( = 0.253). Women, in turn, showed slightly higher mean values but here too, the differences were not statistically significant ( = 0.245).
Asymmetries in the pelvis area are common; they were observed in less than three-quarters of the examined population. Oblique pelvis was found in less than a quarter of women and in more than one-third men with the predominant structural asymmetries. Rotated pelvis was observed in more than one-third of women and men with dominating functional asymmetries. There were no linear correlations between the body mass and height, and the angle of asymmetries.
对称是直立位时正确身体姿势的标准之一。骨盆带的空间定位对其至关重要。腰骶-骨盆-髋关节复合体的功能和结构不对称会对人体许多器官和系统的结构及功能产生重大影响。本研究的目的是展示19至29岁年轻成年人骨盆带选定标志点的倾角仪测量结果。
基于作者原创的临床分类以及体重和身高对所分析不对称性的影响，分析骨盆空间不对称的发生情况。在由300名年轻个体组成的样本中，对骨盆带选定标志点进行倾角仪测量。然后，以髂嵴、髂前上棘和大转子的对齐对称性为标准，根据作者自己的临床分类分析骨盆空间不对称的发生情况。所有不对称度小于1度的研究对象被视为骨盆对称者。
评估了性别、体重和身高对所分析不对称性的影响。仅32%的受访者髂嵴呈对称定位。左侧髂嵴凹陷更为常见——在41%的受访者中出现。女性（44%）比男性（38%）更常出现这种情况。在女性组中，最常观察到的不对称是旋转骨盆（39.4%），而男性则是斜骨盆（40%）。按骨盆不对称亚型进行的更详细分析显示，女性和男性之间存在统计学差异（<0.0001）。对男性骨盆中度旋转的分析显示数值略高，但这些差异无统计学意义（=0.253）。女性的平均值也略高，但同样差异无统计学意义（=0.245）。
骨盆区域的不对称很常见；在不到四分之三的受检人群中观察到。斜骨盆在不到四分之一的女性和超过三分之一的男性中被发现，主要是结构不对称。旋转骨盆在超过三分之一的女性和男性中被观察到，主要是功能不对称。体重、身高与不对称角度之间没有线性相关性。
