[Modification of urge incontinence by biofeedback mechanisms]

Urge incontinence caused by hyperactive urethral closing mechanism can be influenced by relaxation training of the striated sphincter muscle. This is done through a biofeedback mechanism with pelvic floor EMG control. The indications are for urge incontinence with urethral hyperactivity and pelvic floor hyper-reactivity diagnosed through urodynamic examination. Twenty-two female patients with urge incontinence were treated for four weeks by biofeedback training with a portable pelvic floor EMG apparatus. The urge incontinence were improved subjectively and objectively in 73%. The therapy focused on the striated muscle seemed to have better results than therapy of the detrusor.
