Abstract

PURPOSE: The purpose of this study is to evaluate the efficacy of biofeedback 1 treatment and functional electrical stimulation in stress incontinence patients as a physiotherapy and to know which factors affect on the outcome. MATERIALS AND METHOD: A group of 65 patients with stress incontinence were treated with combined alternating biofeedback and intravaginal electrical stimulation during 12 sessions, each 21 minutes in length, during 6 weeks. All patients had type l or ll stress incontinence.
RESULTS
At immediate post treatment, subjective cure(complete dryness) rate was 15% and improvement(recovery to avoid other forms of treatment) rate was 60% and failure rate was 25%. Thus, the overall success rate for this treatment was 75%. In 49 patients who had all scheduled sessions and good compliance, subjective cure rate was 14% and improvement rate was 71%, but in 16 patients not to have good compliance, cure rate was 19%, improvement rate was 25%. In compliant patients, the result of 3 months after treatment showed cure rate was 11%, improvement rate was 54%. Compliance with reatment was the most significant parameter predictive of a good outcome(p<0.01) and the degree of stress incontinence was also significant in compliant patients(p<0.05). No clinical correlation with outcome was found in age, type, severity of cystocele, pelvic muscle strength, initial degree of vaginal contraction. Intravaginal pressure increased by an average of 10cmH20. Increased vaginal pressure was found in 93% of the patients and at least 50%improvement was 61%. Urge incontinence and urgency were present in 10(15%) and 19(29%) of the patients and improvement including cure was found 90% in urge incontinence and 89% in urgency.
CONCLUSIONS
Biofeedback treatment and functional electrical stimulation is more effective for the patients who have good compliance, low degree stress incontinence and combined bladder irritation symptoms. In order to attain and maintain good results, a well structured biofeedback and functional electrical stimulation program that teaches specific muscle exercise should be used and the patients should be followed by a maintenance program and reinforcement.
