Abstract:

Objective To explore the effects of pelvic floor muscle training based on App-based audio guidance on postpartum pelvic floor rehabilitation in primiparas with stress urinary incontinence. Methods A total of 108 pregnant women with stress urinary incontinence were recruited and divided into the experimental group（n=54）and the control group（n=54） by lottery. Patients in the experimental group received audio guided exercises on the basis of routine care. Patients in both groups exercised to 6 months after childbirth. The pelvic floor muscle surface electromyography（sEMG）,exercise compliance and the severity of stress urinary incontinence at 6~8 weeks,3 months,and 6 months after childbirth were compared between the two groups. Results At 6~8 weeks,3 months,and 6 months after childbirth,the compliance of the experimental group with pelvic floor muscle exercise was better than that of the control group（P<0.05）. There was an interaction effect between groups and time in the average sEMG value of type Ⅰ fibers（F=4.702,P=0.011）,and the simple effect analysis showed that the average sEMG value of type Ⅰ fibers in the experimental group were higher than those in the control group at different stages postpartum（P<0.05）. The maximal sEMG value of type Ⅱ fibers was statistically significant between groups（F=13.881,P<0.001）,and the time effects were statistically significant（F=228.685,P<0.001）. The interaction between the invisible group and time was not statistically significant（F=0.664,P=0.517）. There was an interaction effect between groups and time in the average sEMG values of endurance test（F=4.009,P=0.021）.The simple effect analysis showed that at 6~8 weeks,3 months,and 6 months after childbirth,the average sEMG value of endurance test in the experimental group were higher than that in the control group（P<0.05）.The severity of stress urinary incontinence in the two groups were relieved,however,the differences between the groups were not statistically significant（P>0.05）. Conclusion Audio guidance is helpful to improve the compliance with the pelvic floor muscle training of pregnant women therefore improving postpartum pelvic floor muscle strength.
