[Optical-acoustical analogous biofeedback conditioning in the treatment of fecal incontinence in childhood].

This is a report on the treatment of anal incontinence by biofeedback conditioning. Since August 1982 9 children with incontinence (8 rectoanal agenesia, one Morbus Hirschsprung) were treated by simultaneous optical and acoustical analogous biofeedback conditioning. Training of sensitivity and voluntary contractions were performed and controlled electromanometrically. According to the pressure waves electrical alterations were transformed and feedback visually and acoustically. Results of the training of the maximal voluntary contraction are presented and the superiority of this method for the coordination of the anorectal sphincter function is stressed.
