This study aims to examine the relationship between pelvic floor muscle function (PFMF) and pelvic organ prolapse (POP) in a general female population.
Cross-sectional study on women aged 45-85 years. Validated questionnaires were used to assess pelvic floor muscle function. POP and PFMF were evaluated with vaginal examination. For statistical analysis chi-squared test for trend and analysis of variance were used.
Response rate to the questionnaire was 62.7% (1,869/2,979). No significant differences were found in muscle strength and endurance during voluntary muscle contraction between the POP stages. Women with POP stages I and II were significantly less able to achieve effective involuntary muscle contraction during coughing (38.3% and 37.7%) than women without POP (75.2%).
Involuntary contraction of the PFM during coughing (that resulted in stabilization of the perineum) was significantly weaker in the women with POP stage I and II than in the women without POP.
本研究旨在探讨普通女性人群中盆底肌肉功能（PFMF）与盆腔器官脱垂（POP）之间的关系。
对45 - 85岁女性进行横断面研究。使用经过验证的问卷评估盆底肌肉功能。通过阴道检查评估POP和PFMF。统计分析采用趋势卡方检验和方差分析。
问卷回复率为62.7%（1869/2979）。在POP各阶段之间，自主肌肉收缩时的肌肉力量和耐力未发现显著差异。I期和II期POP女性在咳嗽时实现有效非自主肌肉收缩的能力（分别为38.3%和37.7%）明显低于无POP女性（75.2%）。
I期和II期POP女性在咳嗽时盆底肌肉的非自主收缩（导致会阴稳定）明显弱于无POP女性。
