The objective of this study was to compare measurements of pelvic floor muscle extensibility in pregnant women obtained through the Epi-no and perineal elasticity meter (PEM) devices. This was an observational, cross-sectional study with a consecutive sample, conducted in a prenatal care outpatient clinic. The pelvic floors of 62 healthy pregnant women with gestational ages between 35 and 40 weeks were assessed. Perineal extensibility was measured using the Epi-no and PEM devices. Through the linear regression method, a formula was created to calculate the Epi-no values from the PEM values. To determine the degree of relationship between both variables, Pearson's correlation coefficient was used. In the comparison of the results for 62 pregnant women using the two perineal extensibility assessment methods, the value obtained in the Pearson correlation coefficient analysis (0.621) indicated a moderate relationship between the variables. This finding was not confirmed by the Kappa correlation test. When the measurements were classified into three groups, a slight correlation was identified (perineum with restrictions, moderate extensibility, and good extensibility). There was a relationship between Epi-no and PEM from slight to moderate agreement.
本研究旨在比较通过 Epi-no 和会阴弹性测量仪 (PEM) 设备测量的孕妇盆底肌肉伸展度。这是一项观察性、横断面研究，采用连续样本，在产前保健门诊进行。评估了 62 名健康孕妇的盆底，其孕周在 35 至 40 周之间。使用 Epi-no 和 PEM 设备测量会阴伸展度。通过线性回归方法，创建了一个公式，可从 PEM 值计算 Epi-no 值。为了确定两个变量之间的关系程度，使用 Pearson 相关系数进行了分析。在使用两种会阴伸展度评估方法对 62 名孕妇的结果进行比较时，Pearson 相关系数分析（0.621）得出的数值表明变量之间存在中度关系。这一发现未通过 Kappa 相关检验得到证实。当测量结果分为三组时，发现存在轻度相关性（会阴受限、中度伸展和良好伸展）。Epi-no 和 PEM 之间存在从轻度到中度一致的关系。
