肛提肌、尿道括约肌、肛门外括约肌等是组成盆底肌的肌群,在妊娠期阶段,随着孕周的延长及胎儿体重的增加,孕妇的子宫持续增大,增大的子宫会对盆底肌形成压迫,从而导致盆底肌的松弛。近些年的研究显示,盆底肌训练可增加盆底肌肌群的张力,促进孕妇盆底肌群的血液循环,从而提高盆底肌群的收缩力,对促进自然分娩、降低破宫产率和难产率具有十分重要的作用~([1])。情景模拟训练注意是指通过角色扮演、 Levator ani, urethral sphincter, external anal sphincter and other pelvic floor muscles constitute the muscle group, in the gestation stage, with the extension of gestational age and fetal weight gain, the uterus of pregnant women continues to increase, the enlarged uterus will be right Pelvic floor muscle formation of oppression, resulting in pelvic floor muscle relaxation. In recent years, studies have shown that pelvic floor muscle training can increase the tension of the pelvic floor muscles, pelvic floor muscles to promote blood circulation, thereby enhancing the contractility of the pelvic floor muscles, to promote natural childbirth and reduce uterine bleeding Rate and rate of dystocia have a very important role ~ ([1]). Situational simulation training attention is through role play,
