In this study, the role of "levator ani muscles hypertonia" among pathogenetic factors of perineal obstetric injuries is analysed. For this purpose, clinical data of 142 pregnant women, who underwent functional evaluation of perineum during pregnancy and 30 days after delivery were examined. Data here reported are not sufficient to confirm the importance of this factor within the pathogenesis of postpartum perineal deficiency. Levator ani hypertonia on one hand seems to be able to obstruct fetal progression, on the other hand it presumably constitutes, as an expression of a good voluntary control of perineal muscles, a favourable prognostic factor.
在本研究中，分析了“肛提肌高张力”在会阴产科损伤致病因素中的作用。为此，检查了142名孕妇的临床资料，这些孕妇在孕期及分娩后30天接受了会阴功能评估。此处报告的数据不足以证实该因素在产后会阴缺陷发病机制中的重要性。一方面，肛提肌高张力似乎能够阻碍胎儿下降，另一方面，它可能作为会阴肌肉良好自主控制的一种表现，是一个有利的预后因素。
