The pelvic girdle is an important component of the human stabilization system, both during the maintenance of an upright standing position and during motor activities. Frequent functional and structural asymmetries within it can affect the structure and function of many organs and systems of the human body. The mechanism of their occurrence is not fully explained. The objective of the present study was to verify the hypothesis regarding the relationship between the value of pelvic asymmetry and the functional state of muscles that stabilize the lumbo-pelvic-hip complex, as measured by changes in their stiffness. : The study group consisted of 40 young women aged from 19 to 29 years. The observational cross-sectional study incorporated the following elements: an interview, an anthropometric test, an inclinometric assessment of the magnitude of hip girdle rotation utilizing a duometer and tensiomyography. : Analysis of the variables examined in subjects with symmetric or rotated pelvises did not show significant differences between the studied sides in the two groups. Evaluation of associations between the magnitude of pelvic rotation and tensiomyography findings showed that with increased pelvic rotation, the stiffness of the back extensor muscles and the rectus thigh muscles increased only slightly bilaterally, and the contraction rate of the rectus abdominis and biceps thigh muscles decreased. : The results of the tensiomyography study did not unequivocally demonstrate that changes in pelvic symmetry in the transverse plane are associated with dysfunction of the muscles that stabilize the pelvic girdle.
骨盆带是人体稳定系统的重要组成部分，无论是在维持直立站姿还是在运动活动期间。其内部频繁出现的功能和结构不对称会影响人体许多器官和系统的结构与功能。它们发生的机制尚未完全阐明。本研究的目的是验证关于骨盆不对称值与稳定腰-骨盆-髋关节复合体的肌肉功能状态之间关系的假设，通过测量其刚度变化来评估。研究组由40名年龄在19至29岁之间的年轻女性组成。观察性横断面研究包括以下内容：访谈、人体测量测试、使用倾角仪对髋带旋转幅度进行倾角测量评估以及张力肌电图检查。对骨盆对称或旋转的受试者所检查变量的分析未显示两组中研究侧之间存在显著差异。对骨盆旋转幅度与张力肌电图检查结果之间关联的评估表明，随着骨盆旋转增加，背部伸肌和股直肌的刚度仅在双侧略有增加，而腹直肌和股二头肌的收缩率降低。张力肌电图研究结果并未明确表明横平面骨盆对称性的变化与稳定骨盆带的肌肉功能障碍有关。
