〔Abstract〕 Objective To explore the impact of bioelectrical stimulation (BES) therapy on the clinical efficacy and muscle strength in patients with postpartum pelvic floor dysfunction (PPFD). Methods A retrospective study was conducted on 450 PPFD patients admitted to Zhengzhou Maternal and Child Health Hospital from January 2023 to January 2024. The patients who received conventional treatment were included in the control group (225 case)s, and those who received BES treatment in addition to conventional treatment were included in the observation group (225 cases). After treatment, the clinical efficacy and muscle strength indicators were observed in both groups. Results After treatment, the mean voltage of the pelvic floor muscles, maximum voltage of the pelvic floor muscles, and maximum urethral closure pressure in the observation group were higher than those in the control group, and the differences were statistically significant (P < 0.05); the rapid contraction time and maximum value during the pre-rest phase and phase II muscle test, as well as the post-rest phase, were lower in the observation group than in the control group, while the phase I muscle test and endurance test were higher, and the differences were statistically significant (P < 0.05); the sustained contraction pressure and contraction maintenance time of type I and type II muscles in the observation group were higher than those in the control group, and the differences were statistically significant (P < 0.05). Conclusion BES can further enhance the strength of the pelvic floor muscles in patients with postpartum pelvic floor dysfunction, improving their pelvic floor function.
