Abstract：
Background To investigate the differences in pelvic floor muscle (PFM) electromyography (EMG) parameters between women with or without sexual dysfunction (FSD) and their correlations. Methods Women who voluntarily participated in a questionnaire-based survey on sexual function and underwent PFM EMG in Weifang People\'s Hospital during the period from March 2021 to December 2021 were retrospectively enrolled. The female sexual (dys)function was measured using the Female Sexual Function Index. Glazer PFM EMG was performed using a Melander instrument (MLD A2 Deluxe). The differences in PFM EMG parameters between women with or without FSD were compared, and the relationships between PFM EMG parameters and FSD were analysed using multiple linear regression models. Results A total of 305 women were enrolled, with 163 in the FSD group and 142 in the non-FSD group. Comparisons of PFM EMG parameters between these two groups revealed that the FSD group had significantly higher peak EMG amplitude during the phasic (flick) contractions and shorter recovery latency during the tonic contractions than the non-FSD group (both P P Conclusions The results of the pelvic floor EMG in this study suggest that the pelvic floor muscles of women with FSD may be more susceptible to fatigue, and may have poorer coordination of their pelvic floor muscles.
摘要：
背景研究有或没有性功能障碍（FSD）的女性盆底肌（PFM）肌电图（EMG）参数的差异及其相关性。方法回顾性分析2021年3月至2021年12月在潍坊市人民医院自愿参加性功能问卷调查并接受PFMEMG检查的妇女。使用女性性功能指数测量女性性功能（dys）。使用Melander仪器(MLDA2Deluxe)进行GlazerPFMEMG。比较有或没有FSD的女性之间的PFMEMG参数的差异，采用多元线性回归模型分析PFMEMG参数与FSD的关系。结果共纳入305名女性,FSD组163人，非FSD组142人。两组之间PFMEMG参数的比较表明，FSD组在阶段性（轻弹）收缩期间的EMG峰值幅度明显高于非FSD组，而在强直收缩期间的恢复潜伏期则较短（PPP结论本研究中的盆底EMG结果表明，FSD女性的盆底肌肉可能更容易疲劳，盆底肌肉的协调性可能较差。
