摘要
Objective: To investigate the changes of surface electromyography and the therapeutic effects of primipara and multipara with stress urinary incontinence after electrical stimulation combined with biofeedback therapy. Method: We performed a retrospective cohort study of primipara and multipara undergoing electrical stimulation with biofeedback for stress urinary incontinence. The SA9800 therapeutic apparatus was used for biofeedback combined with electrical stimulation to measure the surface EMG signals of pelvic floor muscles before and after treatment. The ICIQ - SF- Chinese and the improvement of patients' self- conscious symptoms were subjectively evaluated. Result: The changes on the sEMG of the pelvic floor muscles:The mean surface electromyography during the pre-quiet phase after treatment in the primipara group, the maximum surface electromyography during the fast muscle test phase, the mean surface electromyography after the resting phase, the sEMG of the slow muscle test phase and the endurance evaluation phase were significantly higher than those before treatment in both groups (P<0.01). The efficacy observation:the maximal surface EMG in the fast muscle test phase of the primipara group, the surface EMG mean in the slow muscle test phase, and the mean changes in the surface EMG in the endurance evaluation phase were significantly higher than those in the multipara (P<0.01), the difference of ICIQ-SF-Chinese in the primipara group was higher than that in the multipara group before and after treatment. The rate of improvement in the conscious symptoms of primipara group was 91.96%, and the rate of improvement in multipara group was 83.95%. Conclusion: Electrical stimulation combined with biofeedback therapy can effectively treat primipara and multipara stress urinary incontinence, and both surface pelvic floor muscle EMG signals are elevated. The primipara pelvic floor muscle function recovers quickly with the better effect than the multipara.
