Abstract：Objective To explore the therapeutic value of combining pelvic floor muscle training with elec-trical stimulation biofeedback in patients with pelvic floor dysfunction.Methods A retrospective analysis was conducted on the clinical data of 120 patients with pelvic floor dysfunction who were treated at Liuzhi Special Dis-trict People's Hospital between January 2022 and June 2023.Based on the treatment methods,patients were divided into the observation group(pelvic floor muscle training combined with electrical stimulation biofeedback,n=60)and the control group(pelvic floor muscle training alone,n=60).The muscle strength and fatigue levels of type Ⅰ and Ⅱmuscle fibers,as well as serum markers related to pelvic floor muscle relaxation,were compared between the two groups.Results Before treatment,there were no significant differences in type Ⅰ and Ⅱ muscle fiber strength and fatigue levels between the two groups(P＞0.05).After treatment,both groups showed improved type Ⅰ and Ⅱ muscle fiber strength and reduced fatigue levels.At 1 month,3 months,and 6 months after treatment,the observation group had a lower proportion of type Ⅰ and Ⅱ muscle fibers with grade Ⅰ-Ⅲ strength and a higher proportion with grade Ⅳ-Ⅴ strength compared to the control group(P＜0.05).Additionally,fatigue levels of type Ⅰ and Ⅱ muscle fibers in the observation group were significantly lower than those in the control group at the same time points(P＜0.05).Before treatment,there were no significant differences between the two groups in serum markers related to pelvic floor muscle relaxation,including relaxin(RLX),nitric oxide(NO),and endothelin-1(ET-1)(P＞0.05).After treatment,RLX and ET-1 levels decreased,while NO levels in-creased in both groups.However,at 1 month,3 months,and 6 months post-treatment,the observation group had significantly lower RLX and ET-1 levels and higher NO levels compared to the control group(P＜0.05).Conclusion The combination of pelvic floor muscle training and electrical stimulation biofeedback effectively improves muscle strength,reduces fatigue,and modulates serum markers related to pelvic floor muscle relaxation in patients with pelvic floor dysfunction.
