Objective To explore the effect of electrical stimulation biofeedback combined with magnetic stimulation in the treatment of postmenopausal female pelvic organ prolapse. Methods A total of 100 postmenopausal female pelvic organ prolapse patients who were admitted to the Second People's Hospital of Guangdong Province from January 2019 to December 2020 were selected as the research objects, and they were divided into the observation group and the control group according to the random number table method, with 50 cases in each group. The control group was given electrical stimulation biofeedback for treatment, and the observation group was treated with magnetic stimulation on the basis of the control group. The treatment cycle of the two groups was 15 weeks. The treatment effect of the two groups were compared, and the grading of pelvic organ prolapse quantitative staging (POP-Q) and pelvic floor muscle strength of the two groups before and after treatment were compared. Results After 15 weeks of treatment, the total effective rate of the observation group was higher than that of the control group, the difference was statistically significant (P＜0.05).The grading of POP-Q of the two groups after 15 weeks of treatment was better than that before treatment, and the grading of POP-Q of the observation group after 15 weeks of treatment was better than that of the control group, the differences were statistically significant (P＜0.05). After 15 weeks of treatment, the pelvic floor muscle strength and the maximum contraction force of the pelvic floor muscle in the two groups were higher than those before treatment, and the continuous contraction time of the pelvic floor muscle in the two groups was longer than that before treatment, the differences were statistically significant (P＜0.05). After 15 weeks of treatment, the pelvic floor muscle strength and the maximum contraction force of the pelvic floor muscle in the observation group were higher than those in the control group, and the continuous contraction time of the pelvic floor muscle in the observation group was longer than that in the control group, the differences were statistically significant (P＜0.05). Conclusion Compared with electrical stimulation biofeedback therapy, electrical stimulation biofeedback combined with magnetic stimulation is more effective in the treatment of pelvic organ prolapse in postmenopausal women, which can effectively improve pelvic floor muscle strength and improve the quality of life of patients.
