Basic vs electromyographic biofeedback-assisted pelvic floor muscle training for the improvement of sexual function after total hysterectomy: a prospective study

Background Pelvic floor muscle training (PFMT) has emerged as a potential intervention to improve post-total hysterectomy (TH) sexual function. Electromyographic (EMG) biofeedback is an adjunct that may improve outcomes. Aim In this study we aimed to compare the EMG biofeedback-assisted PFMT and PFMT alone for improving sexual function in women after TH. Methods For this prospective study we enrolled women undergoing TH in our hospital between January 2022 and April 2023. Participants were divided according to the treatment they selected: EMG biofeedback-assisted PFMT or PFMT alone. Outcomes The primary study outcome was change in patient sexual function evaluated by use of the Female Sexual Function Index. Secondary outcomes were changes in anxiety and depression evaluated with the Hospital Anxiety and Depression Scale score and pelvic floor muscle strength was evaluated with the Glazer assessment performed from before to after treatment. Results A total of 73 patients were included, with 38 patients treated with Electromyographic biofeedback-assisted pelvic floor muscle training. After treatment, sexual function was significantly improved compared to baseline in all patients (all P < .001). Compared to patients with pelvic floor muscle training, the changes in total Female Sexual Function Index scores from before to after treatment in patients with Electromyographic biofeedback-assisted pelvic floor muscle training were significantly higher (all P < .05). There were no significant differences between the 2 groups in the changes in the Glazer score and Hospital Anxiety and Depression Scale scores from before to after treatment (both P > .05). Clinical Translation The results demonstrate that Electromyographic biofeedback-assisted pelvic floor muscle training may be used to improve the sexual function of patients following TH. Strengths and Limitations This study is limited by its single-center design, small sample size, lack of randomization, and absence of estrogen monitoring in enrolled participants. Conclusions Electromyographic biofeedback-assisted pelvic floor muscle training appears to be more effective than pelvic floor muscle training alone in improving sexual function among patients after total hysterectomy.
