Objective To evaluate the effectiveness of electrical stimulation therapy in patients with postpartum pelvic floor dysfunction and provide an objective basis for comprehensive clinical treatment.Methods A total of 150 postpartum women diagnosed with pelvic floor dysfunction within 42 days after delivery at The 903rd Hospital of Joint Logistic Support Force, PLA from January 2017 to December 2022 were selected. They were randomly divided into an observation group (100 cases) and a control group (50 cases). The observation group received pelvic floor electrical stimulation therapy based on standard Kegel exercises, while the control group only underwent standard Kegel exercises. The efficacy was determined by measuring the transverse axis, longitudinal axis, and area size of the levator ani hiatus using MRI and assessing muscle electromyography values with a pelvic floor measurement instrument.Results In the observation group, the transverse axis and area size of the levator ani hiatus significantly decreased after treatment, with statistical differences compared with the control group (P<0.05). The total muscle electromyography values and electromyography values of type I and type II muscle fibers in the observation group were all superior to those before treatment, with statistical differences compared with the control group (P<0.05).Conclusion The combination of pelvic floor electrical stimulation therapy and Kegel exercises is more effective in patients with postpartum pelvic floor dysfunction and is worthy of clinical application and promotion.
