Abstract

Abstract:

Objective

To evaluate the clinical efficacy of magnetic stimulation combined with biofeedback in the treatment of pelvic floor dysfunction disease (PFD), to observe its effect on pelvic floor surface electromyography, and to provide evidence for improving the efficacy of PFD.

Methods

Patients diagnosed with PFD and treated at our hospital from January 2021 to June 2022 were selected and divided into either a biofeedback group (control group) or a magnetic stimulation combined with biofeedback group (observation group) according to the patient's wish. The onset time, clinical symptom score, effective rate, and pelvic floor electromyography value of the two groups after treatment were compared.

Results

A total of 134 patients were included in this study, including 73 cases in the observation group and 61 cases in the control group. The number of treatment times of the observation group and control group were 3 and 8, respectively, and the effective rates were 93.15% and 65.57%, respectively, both of which differed significantly between the two groups. Clinical symptom scores improved more significantly in the observation group than in the control group. Pelvic floor muscle strength was more significantly improved in the observation group than in the control group.

Conclusion

Magnetic stimulation combined with biofeedback can shorten the time to onset of pelvic floor rehabilitation, significantly improve the symptoms of PFD, and significantly improve the strength and endurance of pelvic floor muscle, which can be used as the first choice of treatment for moderate to severe PFD. However, due to the small number of cases observed in this study and short follow-up time, multi-center controlled experimental study and long-term efficacy follow-up are still needed to confirm its value.
