INTRODUCTION AND HYPOTHESIS
It has been suggested that repositioning pelvic organ prolapse (POP) by pessary support may improve pelvic floor muscle (PFM) function. The aim of the present study was to compare vaginal resting pressure and maximal voluntary contraction (MVC) of the PFM measured with and without a ring pessary in situ.
METHODS
This was a short-term experimental study with women acting as their own controls. Twenty-two women with POP quantified II-IV were included. Vaginal resting pressure and MVC was measured with a manometer (Camtech AS) in supine position. Difference between measurements with and without the ring pessary was analyzed by paired sample t test and Wilcoxon signed rank test. Significance level was <0.05.
RESULTS
There was a statistically significant difference in measurement of vaginal resting pressure (p <0.01) but not of MVC (p= <0.68) with the ring pessary in situ.
CONCLUSIONS
Measurement of PFM strength can be done without repositioning the prolapse.
引言与假设
有人提出，通过子宫托支撑来重新定位盆腔器官脱垂（POP）可能会改善盆底肌肉（PFM）功能。本研究的目的是比较在放置和不放置环形子宫托的情况下测量的PFM阴道静息压力和最大自主收缩（MVC）。
方法
这是一项短期实验研究，女性作为自身对照。纳入了22名POP量化为II-IV级的女性。在仰卧位使用压力计（Camtech AS）测量阴道静息压力和MVC。通过配对样本t检验和Wilcoxon符号秩检验分析放置和不放置环形子宫托时测量结果的差异。显著性水平为<0.05。
结果
放置环形子宫托时，阴道静息压力测量存在统计学显著差异（p <0.01），但MVC测量无显著差异（p = <0.68）。
结论
无需重新定位脱垂即可测量PFM强度。
