Abstract

Objective To investigate the efficacy of intravascular smooth muscle stimulation combined with traditional electrical stimulation in the treatment of postpartum myofascial pelvic pain syndrome (MPPS). Methods A total of 120 postpartum MPPS patients admitted to the Pelvic Floor and Urological Rehabilitation Center of Dalian Women and Children's Medical Center (Group) from June 2023 to December 2024 were randomly divided into a lifestyle guidance group，a traditional electrical stimulation group，and a combined electrical stimulation group，with 40 patients in each group. The visual analog scale score for pelvic floor myofascial tenderness，pain-related clinical symptoms，pelvic floor muscle strength，pelvic floor electrophysiological parameters and overall effective rate were compared before and after treatment. Results There were no significant differences in the VAS scores for pelvic floor myofascial tenderness，pain-related clinical symptoms，pelvic floor muscle strength or pelvic floor electrophysiological parameters among the three groups before treatment (P>0.05). After treatment，the aforementioned indicators improved in all groups，with more significant improvements in the combined group (P<0.05). The overall effective rate in the combined electrical stimulation group was higher than that in the traditional electrical stimulation group and the lifestyle guidance group，with a statistically significant difference (P<0.05). Only a few patients experienced adverse reactions such as mild soreness or dizziness，which were relieved after adjusting the current intensity，and no serious adverse events occurred. Conclusions The combination of intravascular smooth muscle stimulation (CMLV) with traditional electrical stimulation is effective，safe and reliable in the treatment of postpartum MPPS，which can significantly reduce pelvic floor muscle pain，improve pain-related clinical symptoms，decrease pelvic floor muscle fatigue，enhance pelvic floor muscle strength and voluntary contraction ability，and improve pelvic-abdominal coordination. It is worthy of clinical promotion and application.
