| Objective:To objectively analyze the therapeutic effect of pelvic floor muscle exercise combined with biofeedback electrical stimulation on the recovery of pelvic floor muscle function in women in different postpartum periods. Methods: A total of 39 women with mild pelvic organ prolapse were admitted from September 2020 to November 2021 in the rehabilitation outpatient clinic. The patients were divided into the early group (within 45 days after delivery) and the late group (3 months after delivery) according to the starting treatment time. All women received the same pelvic floor rehabilitation therapy. By analyzing the results of pelvic floor surface electromyography and three-dimensional pelvic floor ultrasonography before and after treatment, the effects of rehabilitation therapy on the recovery of pelvic floor function of the two groups were compared. Results: After 8 weeks of pelvic floor rehabilitation, the mean of slow muscle and endurance of the pelvic floor muscles of the two groups were increased (all P<0.05).The scores of slow muscles,endurance scores and total scores of pelvic floor muscles were increased in the two groups (all P<0.05).The improvement of type II muscle score, endurance score, and total score in the early group was significantly greater than in the late group, and the difference was statistically significant. After the intervention, while the patients performed Valsalva, the improvement of bladder neck mobility in the early group was greater than in the late group, and the difference was statistically significant (P<0.05). The area of the levator hiatus decreased in both groups (both P<0.05). In the early group, when the patients performed Valsalva, the position of the bladder neck was significantly higher than that before treatment, while the mobility of the bladder neck and the posterior angle of the bladder were statistically reduced compared with those before treatment (P<0.05). Conclusion: Early postpartum biofeedback electrical stimulation combined with pelvic floor muscle rehabilitation can more effectively enhance the postpartum pelvic floor muscle strength and endurance, improve the degree of pelvic floor organ prolapse, and the therapeutic effect is ideal, which is worthy of clinical application. |
