There seems to be little knowledge about pelvic floor muscles (PFMs) in the general population; however, literature confirming this assertion is scarce, especially in developing countries. The present study hypothesized a low level of knowledge about PFMs in a sample of Brazilian women and a positive relationship between that knowledge and the ability to contract the PFMs, strength, and urinary continence.
This was a cross-sectional study including 133 women. A questionnaire assessing knowledge about PFMs and the International Consultation on Incontinence Questionnaire-Short Form (ICIQ-UI-SF) were applied. Vaginal palpation and manometry were used to assess PFM condition. Pearson's correlation coefficient was used to test the association between PFM knowledge and continuous variables, and Fisher's exact test was used to compare the women's PFM knowledge with the categorical variables.
A low level of PFM knowledge was observed in this sample, with a mean total score of 0.48 (±0.97). Vaginal manometry peak, mean, and duration values were 39.1 cmHO (±23.7), 25.5 cmHO (±16.1), and 21.1 s (±20.8) respectively. The ICIQ-UI-SF mean score was 7.1 (± 6.8). There were weak correlations between PFM knowledge and age (r -0.2044/ p = 0.01), and parity (r -0.19568/p = 0.02). PFM knowledge was higher among women with higher education levels (p = 0.0012) and those who had previously performed PFM training (p <0.001).
The participants showed a low level of PFM knowledge. No relationship between PFM knowledge and ability to contract or prevalence of UI was observed.
普通人群对盆底肌肉（PFMs）的了解似乎很少；然而，证实这一说法的文献很少，尤其是在发展中国家。本研究假设巴西女性样本对PFMs的了解程度较低，且这种了解与PFMs收缩能力、力量和尿失禁之间存在正相关关系。
这是一项横断面研究，纳入了133名女性。应用了一份评估PFMs知识的问卷和国际尿失禁咨询委员会简表（ICIQ-UI-SF）。采用阴道触诊和压力测定法评估PFMs状况。使用Pearson相关系数检验PFMs知识与连续变量之间的关联，使用Fisher精确检验比较女性的PFMs知识与分类变量。
该样本中PFMs知识水平较低，平均总分0.48（±0.97）。阴道压力测定的峰值、平均值和持续时间值分别为39.1 cmH₂O（±23.7）、25.5 cmH₂O（±16.1）和21.1秒（±20.8）。ICIQ-UI-SF平均得分为7.1（±6.8）。PFMs知识与年龄（r = -0.2044，p = 0.01）和产次（r = -0.19568，p = 0.02）之间存在弱相关性。受过高等教育的女性（p = 0.0012）和之前接受过PFMs训练的女性（p <0.001）的PFMs知识水平较高。
参与者对PFMs的了解程度较低。未观察到PFMs知识与收缩能力或尿失禁患病率之间的关系。
