The purpose of this study was to clarify the reliability and validity of pelvic floor muscle (PFM) strength assessment using the MizCure perineometer in healthy women.
Twenty healthy women (age 20-45 years) participated in this study. The vaginal pressure measured using the MizCure and validated Peritron perineometers were repeated during PFM contraction in the supine and standing positions. All women were evaluated twice by examiners 1 and 2. Following the measurements in the first session (Test 1), they were repeated after an interval of between 2 and 6 weeks (Test 2). Within- and between-session intra- and inter-rater reliabilities in vaginal pressure were analyzed using intraclass correlation coefficients (ICC) (1, 1) and (2, 1), respectively. Validity was assessed by Pearson's product-moment correlation coefficient and Spearman's rank correlation analysis.
Within-session intra-rater reliabilities for both examiners 1 and 2 for all vaginal pressures in Tests 1 and 2 were 0.90-0.96 for both perineometers. Between-session intra-rater reliability for the MizCure was 0.72-0.79 for both positions for examiner 1, and 0.63 in the supine position and 0.80 in the standing position for examiner 2. Inter-rater reliability for Test 1 was 0.91 in the supine position and 0.87 in the standing position for the MizCure. The vaginal pressures using the MizCure and Peritron were significantly associated with the supine position (r = 0.68, P < .001) and the standing position (r = 0.82, P < .001).
MizCure perineometer is a validated tool to measure PFM strength in both supine and standing positions in healthy nulliparous women.
本研究旨在明确 MizCure 会阴测量仪评估健康女性盆底肌（PFM）力量的可靠性和有效性。
20 名健康女性（年龄 20-45 岁）参与了本研究。在仰卧位和站立位收缩 PFM 时，使用 MizCure 和经过验证的 Peritron 会阴测量仪测量阴道压力。所有女性均由评估员 1 和 2 进行两次评估。在第一次测试（测试 1）中进行测量后，间隔 2-6 周（测试 2）后重复测量。使用组内相关系数（ICC）（1,1）和（2,1）分别分析阴道压力的组内和组间测试内和测试间的内部可靠性。通过 Pearson 积矩相关系数和 Spearman 秩相关分析评估有效性。
在测试 1 和 2 中，所有阴道压力的测试内评估员 1 和 2 的组内可靠性对于两种会阴测量仪均为 0.90-0.96。MizCure 在仰卧位和站立位的评估员 1 的测试间组内可靠性分别为 0.72-0.79，而评估员 2 的仰卧位为 0.63，站立位为 0.80。测试 1 的组间可靠性对于 MizCure，仰卧位为 0.91，站立位为 0.87。MizCure 和 Peritron 的阴道压力与仰卧位（r=0.68，P<.001）和站立位（r=0.82，P<.001）显著相关。
MizCure 会阴测量仪是一种在仰卧位和站立位测量健康未产妇 PFM 力量的有效工具。
