盆底表面肌电评价盆底肌功能在高雄激素患者中的研究

Surface electromyography evaluation of pelvic floor muscles in hyperandrogenism women

目的探讨盆底表面肌电(sEMG)评价高雄激素女性和正常女性盆底肌功能是否存在差异。方法选取2016年7月至2017年7月在广州市妇女儿童医疗中心妇科门诊经详细问病史和临床相关检查后确诊为多囊卵巢综合征(PCOS)且未生育但有性生活的高雄激素患者79例,同期选取86例未生育有性生活且雄激素水平正常的育龄妇女为对照组。应用标准的Glazer盆底sEMG评估方案及设备,测定研究对象的阴道括约肌sEMG值来评估两组盆底肌功能。结果两组在年龄、身高及体质量指数比较均无显著性差异(均P>0.05),PCOS组血游离睾酮水平显著高于对照组(t=3.261,P<0.05)。PCOS组快速收缩阶段最大收缩波幅、持续收缩阶段收缩波幅平均值均显著高于对照组(t值分别为15.943、10.925,均P<0.05),两组前基线阶段波幅平均值、快速收缩反应时间、耐久收缩波幅平均值、后基线波幅平均值比较均无显著性差异(t值分别为2.751、1.034、6.314、0.778,均P>0.05)。结论盆底sEMG值可在一定程度上简便、客观地反映盆底肌群的功能,雄激素与盆底肌肉功能存在一定的联系。

Objective To assess the difference in pelvic floor muscle surface electromyography（sEMG）between hyperandrogenism women and normal women.Methods Seventy-nine hyperandrogenism women who were diagnosed as polycystic ovary syndrome（PCOS）through detailed medical history inquisition and relative medical checks in outpatient department of Guangzhou Women and Children Medical Center from July 2016 to July 2017 and had sexual life but no childbirth were selected as PCOS group.Eighty-six women of childbearing age with normal androgen level with sexual life and without childbirth were selected as control group at the same period.Pelvic floor muscle function in two groups was assessed through sEMG value of vaginae sphincter,detected by using standard Glazer pelvic sEMG evaluation plan and device.Results There were no significant differences in age,height and body mass index between two groups（all P〉0.05）.Level of free testosterone in PCOS group was significantly higher than that in control group（P〈0.05）.Fast maximum contraction amplitude and average value of sustained contraction phase contraction amplitude in PCOS group were significantly higher than those in control group（t value was 15.943 and 10.925,respectively,both P〈0.05）.There were no significant differences in anterior baseline average amplitude,fast contraction response time,durable contraction amplitude average value,posterior baseline average amplitude between two groups（t value was 2.751,1.034,6.314 and0.778,respectively,all P〉0.05）.Conclusion Pelvic floor muscle sEMG can in some degree indicate the function of pelvic floor muscles concisely and objectively.There is relationship between androgen and pelvic floor muscle function.
