〔Abstract〕 Objective To explore the effect of Kegel pelvic floor rehabilitation treatment on pelvic floor function after natural delivery. Methods A total of 118 parturients who received natural delivery in Xinxiang Central Hospital from January 2020 to June 2022 were selected, including 59 parturients who received conventional postpartum rehabilitation treatment into a control group, and 59 parturients who received Kegel pelvic floor rehabilitation treatment on the basis of conventional treatment into an observation group. The puerperal surface electromyography indexes, pelvic floor muscle strength indexes and pelvic floor function indexes were compared between the two groups. The incidence of postpartum pelvic floor complications of two groups was analyzed after 3 months of follow-up. Results After treatment, the indexes of pre-resting period, Class Ⅱ muscle test period and postresting period in the observation group were lower than those of the control group, while the indexes of class Ⅰ muscle test period and endurance test were higher than those of the control group, the difference was statistically significant (P < 0.05). After treatment, the sustained systolic blood pressure and systolic maintenance time of class Ⅰ and Ⅱ muscles in the observation group were higher than those of the control group, and the difference was statistically significant (P < 0.05). After treatment, the 1 h urine leakage and PFIQ-7 scores of the observation group were lower than those of the control group, and the difference was statistically significant (P < 0.05). The total incidence of postpartum pelvic floor complications in the observation group was lower than that of the control group, and the difference was statistically significant (P < 0.05). Conclusion Kegel pelvic floor rehabilitation treatment can better improve postpartum pelvic floor function and reduce the risk of postpartum pelvic floor complications.
