Study On The Effect Of Pelvic Floor Muscle Training During Pregnancy On Delivery Outcome And Prevention Of Perinatal Stress Urinary Incontinence

Background:The incidence of pelvic floor dysfunction is high,among which urinary incontinence is the most common.The most common causes of pelvic floor muscle damage are pregnancy and delivery.Pelvic floor muscle training plays an effective role in the prevention and treatment of urinary incontinence during pregnancy and postpartum.Nowadays,most studies focus on the treatment experience of postpartum pelvic floor functional rehabilitation.With the continuous development of modern science and technology,the time of rehabilitation intervention continues to advance,so it is urgent to explore pelvic floor muscle training for prenatal women.Objective:To analyze the optimal timing of pelvic floor muscle training（PFMT）during pregnancy and early postpartum,fully understand the important role of pelvic floor muscle training in women’s health and disease prevention during pregnancy and early postpartum,reduce the incidence of stress urinary incontinence（SUI）during pregnancy and early postpartum,and improve women’s quality of life（QOL）.Methods:The clinical randomized controlled trial was used in this trial.200 pregnant women who underwent regular antenatal examination in the Department of Obstetrics of SUIzhou Central Hospital from 01 June 2020 to 31 August 2020 were randomly divided into control group and 3 test groups.The health education during pregnancy and postpartum was routinely carried out in the control group.On the basis of the intervention in the control group,pelvic floor muscle training was carried out under the g SUIdance of doctors from the 14 th week of pregnancy in test group 1,and pelvic floor muscle training was carried out 3 times per week in test group 2.Experimental group 3 carried out this training from 28 weeks of pregnancy,with a frequency of 3 times per week.Using APP platform sign-in supervision mechanism,telephone follow-up of their exercise,to ensure the completion and effectiveness of the training.The delivery outcomes of the four groups were compared and the incidence of stress urinary incontinence in the third trimester and early postpartum period of the four groups was analyzed and compared through the questionnaire survey of the International Advisory Committee on stress urinary Incontinence questionnaire.Results:According to the inclusion and exclusion conditions,153 pregnant women took part in the whole process of the trial.The clinical data of the four groups were compared.There was no significant difference in age,body mass index（BMI）and gestational weeks among the four groups.After training pelvic floor muscles during pregnancy and early postpartum,the delivery outcome and stress urinary incontinence in late pregnancy and early postpartum were compared among the four groups.In terms of cesarean section rate,the rate of cesarean section in group 1 was significantly lower than that in the control group（P < 0.05）,and the incidence of stress urinary incontinence in the third trimester and postpartum was significantly lower than that in the control group（P < 0.05）.The proportion of late and postpartum stress urinary incontinence in group 1 was lower than that in group 2（P < 0.05）,and the proportion of stress urinary incontinence in late pregnancy and early postpartum in group 2 was lower than that in group 3（P < 0.05）.The pelvic floor muscle strength of the test group was higher than that of the control group（P < 0.05）.Conclusion:Timely and full pelvic floor muscle training during pregnancy can reduce the rate of cesarean section,reduce the risk of stress urinary incontinence during pregnancy and early postpartum,and improve their quality of life.
