Objective To explore the effect of bionic electrical stimulation (BES) combined with resistance tightening leg training on postpartum pelvic floor dysfunction (PFD). Methods A total of 205 patients with PFD were divided into BES group (n=102) and the combined group (n=103) by random number table method. All of them received routine pelvic floor muscle training. In addition, the BES group was treated with BES intervention, and the combined group was treated with BES combined with resistance tightening leg training, with 8 weeks of treatment. The classification of pelvic floor muscle strength, electrophysiological indexes of pelvic floor function, urodynamics and stress urinary incontinence (SUI) classification/pelvic organ prolapse (POP) degree were compared between the two groups before and after treatment. Results After treatment, the pelvic floor muscle strength classification, SUI classification and POP degree in the combined group were significantly better than those in BES group (P< 0.05). After treatment, ClassⅠ/ ClassⅡmuscle fiber fatigue, vaginal dynamic pressure and maximal electromyography (EMG) value of fast muscle in the combined group were (-1.20±0.35)%, (-0.90±0.30) %, (76.30±5.51) cmH2O, (43.00±5.82) μV, respectively, which were all significantly higher than those in BES group (P<0.05). After treatment, the indexes of urodynamics in both groups were significantly improved, and the combined group was better than the BES group (P<0.05). Conclusions BES combined with resistance tightening leg training can significantly improve pelvic floor muscle strength, muscle fiber fatigue and urodynamics in patients with PFD, thus alleviating SUI/POP symptoms.
