Abstract: Objective To analyze the clinical effect of electrical stimulation biofeedback therapy combined with pelvic floor muscle exercise in the postpartum rehabilitation of pelvic floor dysfunction. Methods 72 patients with postpartum pelvic floor dysfunction from the People's Hospital of Inner Mongolia Autonomous Region from January 2022 to December 2022, randomized into control group and observation group, 36 cases in each group, the control group received regular pelvic floor muscle exercises, the observation group received electrical stimulation biofeedback therapy combined with pelvic floor muscle exercise, the pelvic floor muscle related indicators (mixed muscle mean EMG value, slow muscle mean EMG value, anterior resting mean EMG value, posterior resting mean EMG value, fast muscle maximum EMG value), quality of life, urodynamic indicators and adverse events were compared between two groups. Results In the observation group, the pelvic floor muscle related indicators, quality of life, maximum urethra closure pressure (PMUC) and Valsalva of urine leakage point pressure (PVLP) were higher than those of the control group, and the 1-hour pad test (1 HPrV) and the risk of adverse reactions were lower than those of the control group, statistically significant (P<0.05). Conclusion For the patients with postpartum pelvic floor dysfunction, the combination of electrical stimulation biofeedback therapy with pelvic floor muscle exercise has a very positive significance. It can effectively promote the recovery of postpartum pelvic floor muscle function, and can well control the risk of adverse reactions, thus significantly improving the maternal quality of life, and has clinical application value.
