abstract: The overall success rate of biofeedback in ano-rectal incontinence and chronic constipation is reported to be 50-92% and 35-90%, respectively. In patients with neurogenic incontinence, the results are poor. Biofeedback, in case of outlet obstruction, seems only to be useful if there is paradoxical contraction of the external anal sphincter and/or the puborectalis muscle during straining (anismus). Further investigations to select patients who would profit from this therapy are, therefore, necessary.
