The effect of biofeedback pelvic floor training on female stress urinary incontinence

Objective To analyze the effect of biofeedback pelvic floor training on female stress urinary incontinence. Methods Six patients with stress urinary incontinence underwent biofeedback pelvic floor training from September,2003 to Janurary,2004. The mean age was 44(31～61) years. Five cases were diagnosed with stress urinary incontinence only and the other one with mixed urinary incontinence, according to medical history and physical examination. The pelvic muscle electromyography was measured with Femiscan Biofeedback Clinical Set. The treatment course was 8 to 12 weeks and twice per week. Four patients completed the treatment, and 2 are still underway. The effect was evaluated by pelvic muscle electromyography and symptoms release. Results Among 4 patients with completed treatment, the pelvic muscle electromyography increased 4 44 times (from 9 7μV to 42 9μV). Three patients who were younger than 40 years released symptoms after 4 to 6 week training. A 61 years old patient did not obtain improvement yet. No side-effect was observed during the treatment. Conclusions Biofeedback pelvic floor training for female stress urinary incontinence is a safe and effective treatment, especially for young patients.
