The human pelvis is subjected to forces generated by abdominal muscles. Pelvic asymmetry (PA) might therefore be related to the asymmetrical postural activity of the lateral abdominal muscles (LAMs: transversus abdominis (TrA); internal oblique (IO); external oblique (EO)). The main aim of this study was to evaluate the potential relationship between PA, expressed by the asymmetry index in the frontal (PAIf) and sagittal (PAIs) planes and LAM postural activity as described by the tissue deformation index (TDI). A group of 126 healthy volunteers (59 females) was involved. Positions of the anatomic landmarks for PA measurement were registered by the motion capture system. The response of LAMs to postural disturbation was recorded using the M-mode ultrasounds. We found weak negative correlations between PAIf and TDI values as well for the right and the left side of the body except for EO muscle (PAIf-TRA right: r = -0.11, left: r = -0.06; PAIf-IO right: r = -0.15, left: r = -0.10; PAIf-EO right: r = 0.02, left: r = 0.12). On the contrary, analysis between PAIs and TDI values revealed weak positive correlations, also except for EO muscle (PAIf-TRA right: r = 0.004, left: r = 0.003; PAIf-IO right: r = 0.05, left: r = 0.06; PAIf-EO right: r = 0.07, left: r = -0.02). For all tested correlations, we recorded non-significant outcomes (all p > 0.05). We found no evidence to support the claim that PA is related to the LAM activity in the group of young, healthy, and active people.
人类骨盆受到腹部肌肉产生的力的作用。因此，骨盆不对称（PA）可能与侧腹部肌肉（LAMs：腹横肌（TrA）、腹内斜肌（IO）、腹外斜肌（EO））的不对称姿势活动有关。本研究的主要目的是评估由额面（PAIf）和矢状面（PAIs）不对称指数表示的PA与由组织变形指数（TDI）描述的LAM姿势活动之间的潜在关系。研究纳入了一组126名健康志愿者（59名女性）。通过运动捕捉系统记录用于测量PA的解剖标志点的位置。使用M型超声记录LAMs对姿势干扰的反应。我们发现，除了EO肌肉外，PAIf与身体右侧和左侧的TDI值之间均存在弱负相关（PAIf-TRA右侧：r = -0.11，左侧：r = -0.06；PAIf-IO右侧：r = -0.15，左侧：r = -0.10；PAIf-EO右侧：r = 0.02，左侧：r = 0.12）。相反，PAIs与TDI值之间的分析显示存在弱正相关，同样除了EO肌肉（PAIf-TRA右侧：r = 0.004，左侧：r = 0.003；PAIf-IO右侧：r = 0.05，左侧：r = 0.06；PAIf-EO右侧：r = 0.07，左侧：r = -0.02）。对于所有测试的相关性，我们记录到无显著结果（所有p > 0.05）。我们没有发现证据支持PA与年轻、健康且活跃人群组中的LAM活动有关这一说法。
