Abstract: ObjectiveTo explore the effect of biofeedback and electrical stimulation combined with Kegel exercises on parturients with pelvic floor muscles lower than grade Ⅲ.MethodsTotally 300 parturients with pelvic floor muscle strength lower than grade Ⅲ treated in our hospital from January 2020 to March 2021 were recruited and divided into 2 groups with random number table method.The control group(n 150) received Kegel exercises and the intervention group(n 150) received biofeedback and electrical stimulation combined with Kegel exercises. The intervention effect, pelvic floor function and self-training frequency were compared between the two groups 2 month post-intervention.ResultsThe effective rate of the intervention group was 97. 33%(146/150),which was higher than that of the control group 86. 67%(130/150)(P< 0. 05). After intervention, pelvic floor function(resting pelvic floor pressure, pelvic floor systolic pressure), and weekly self-training frequency of the two groups all increased. Weekly selftraining frequency of the intervention group was higher than the control group(P< 0. 05).ConclusionThe application of biofeedback and electrical stimulation combined with Kegel exercises can improve pelvic floor function, increase weekly self-training frequency and intervention effect among parturients with pelvic floor muscle strength lower than grade Ⅲ.
