Abstract:

BACKGROUND: Biostimulation feedback treatment has been widely used for female stress urinary incontinence. The treatment principle is based on the electromyographic signal measured and the combination of biofeedback technique and electrotherapy technique.
OBJECTIVE: To evaluate the effect of biofeedback electrical stimulation in treatment of female stress urinary incontinence.
METHODS: Thirty female patients suffering from light or moderate stress urinary incontinence received biofeedback electrical stimulation for 4-8 weeks. The stimulation parameters were 60 Hz, 20-60 mA, 12-second feedback. The patients were instructed to contract pelvic floor muscle. The peak value of surface electromyography in pelvic floor muscular 2-second-rapid-contraction, mean value of pelvic floor muscular 10-second-contraction, mean value of the pelvic floor muscular 60-second-tolerance-contraction, and the rate of urine leakage were observed before and after treatment.
RESULTS AND CONCLUSION: The peak value of surface electromyography in pelvic floor muscular 2-second-rapid-contraction, mean value of pelvic floor muscular 10-second-contraction, and mean value of the pelvic floor muscular 60-second-tolerance-contraction were significantly increased after treatment, compared with before treatment (P < 0.05). The rate of urine leakage was decreased obviously after treatment (P < 0.05). Biofeedback electrical stimulation can significantly increase surface electromyography value of pelvic floor muscles during contraction, and is an effective treatment for female stress urinary incontinence.
