Abstract To explore the efficacy of pelvic floor electromyographic biofeedback for treating perimenopausal women with pelvic floor dysfunction, and to study its influence on the bladder function and urodynamic state of these women. Methods: 108 perimenopausal women with pelvic floor dysfunction were selected and were divided into two groups (54 cases in each group) by the simple randomization method from January 2021 to January 2022. The women in the two groups were given routine pelvic floor muscle rehabilitation exercise for 3 months continuously, and the women in the observation group were given pelvic floor electromyographic biofeedback therapy additionally. The pelvic floor muscle strength, the values of bladder function indexes, such as the first bladder volume (FVS), the maximum bladder volume (MVS), and the post-voiding residual volume (PVR), the values of urodynamics indexes, such as average urine flow rate (AFR), maximum urine flow rate (MFR), and urination time, and the quality-of-life score by Pelvic Floor Impact Questionnaire 7 (PFIQ-7) of the women before treatment and after 3 months of treatment were compared between the two groups. Results: There was significant difference in the pelvic floor muscle strength of the women after 3 months of treatment between the two groups (P<0.05). The values of FVS, MVS, AFR, and MFR of the women in both groups after treatment had increased significantly, and which of the women in the observation group (234.78±12.65ml, 435.95±14.28ml, 22.78±2.15ml/s, and 26.95±2.28 ml/s) were significantly higher than those (216.38±10.59ml), 428.86±13.40 ml, 20.38±2.29 ml/s, and 24.86±2.40 ml/s) of the women in the control group. The values of PVR, urination time, and PFIQ-7 score of the women in the two groups after treatment had decreased significantly, and which (5.49±2.07ml, 22.49±3.04s, and 40.78±8.15 points) of the women in the observation group were significantly lower than those (8.52±2.25ml, 26.53± 3.24s, and 50.33±12.25 points) of the women in the control group (all P<0.05). Conclusion: Pelvic floor electromyographic biofeedback therapy of the perimenopausal women with pelvic floor dysfunction can effectively improve their bladder function and promote their recovery of pelvic floor muscle strength, and which is beneficial to the prognosis of these women.
