The purpose of this study was to demonstrate the reproducibility of an objective scale utilizing a tampon to assess pelvic muscle strength and to compare it to a digital evaluation of muscle strength [1]. Thirty women presenting to the office were enrolled in the study. Their pelvic floor muscle strength was separately assessed by both examiners using both scales. The reproducibility of the scales was then analyzed by Cohen's kappa measure of interrater agreement. The tampon scale was found to have a measure of agreement of 0.76 (excellent interrater agreement if >0.75). In contrast, the digital scale was found to have a measure of agreement of 0.68 (fair agreement if 0.40-0.75). Therefore, the tampon scale is an easy and reproducible approach for assessing pelvic floor muscle strength.
本研究的目的是证明使用棉塞评估盆底肌肉力量的客观量表的可重复性，并将其与肌肉力量的指诊评估进行比较[1]。30名前来就诊的女性参与了该研究。两位检查者分别使用这两种量表对她们的盆底肌肉力量进行评估。然后通过科恩kappa评分者间一致性测量法分析量表的可重复性。结果发现棉塞量表的一致性评分为0.76（评分者间一致性极佳，若>0.75）。相比之下，指诊量表的一致性评分为0.68（一致性尚可，若为0.40 - 0.75）。因此，棉塞量表是评估盆底肌肉力量的一种简便且可重复的方法。
