Biofeedback therapy for anorectal disorders in children.

The physiological rationale, methodology, and results of biofeedback therapy in the management of anorectal disorders in children are presented. Balloon manometry and surface electromyography (EMG) are current biofeedback methods used to teach improved recognition of rectal distension and coordination of muscle function to either maintain fecal continence or to allow proper defecation. These techniques have permitted a success rate of over 70% in the management of children with functional or organic anorectal disease refractory to conventional medical and behavioral therapy. Biofeedback therapy is recommended to assist in the successful rehabilitation of these patients.
