The aim of the study was to assess pelvic floor function and dysfunction using intravaginal devices (IVD test). One hundred and eighty-five patients were evaluated, 65 (35.1%) in the control group without genital prolapse and 120 (64.9%) in the study group, with prolapse. Anatomic changes were evaluated on a scale described by Halban, and functional classification based on palpation of the muscles of the pelvic floor during contraction. Additionally, weighted vaginal devices were used to assess pelvic floor function. Statistic analysis was performed with the Spearman-Pearson correlation coefficient, the chi2 test and the response/operator characteristic curve. There was an acceptable correlation between the IVD test and the functional classification of 0.75. Using this classification, the IVD test showed 86.58% sensitivity, 75.72% specificity, and had a positive predictive value of 73.95% and a negative predictive value of 87.64%. Significant differences between pelvic floor muscle activity in those patients with and without genital prolapse were observed (chi2 = 58.28, P=<0.005). It was concluded that pelvic floor assessment can be done through the evaluation of active muscle strength or pelvic floor integrity using the functional classification and the IVD test.
本研究的目的是使用阴道内装置评估盆底功能和功能障碍（IVD测试）。对185例患者进行了评估，其中对照组65例（35.1%）无生殖器脱垂，研究组120例（64.9%）有脱垂。根据Halban描述的量表评估解剖学变化，并根据收缩时盆底肌肉的触诊进行功能分类。此外，使用加权阴道装置评估盆底功能。采用Spearman-Pearson相关系数、chi2检验和反应/操作者特征曲线进行统计分析。IVD测试与功能分类之间的相关性良好，为0.75。使用该分类，IVD测试的敏感性为86.58%，特异性为75.72%，阳性预测值为73.95%，阴性预测值为87.64%。观察到有和无生殖器脱垂患者的盆底肌肉活动存在显著差异（chi2 = 58.28，P<0.005）。得出的结论是，可以通过使用功能分类和IVD测试评估主动肌肉力量或盆底完整性来进行盆底评估。
