Biofeedback by means of an anorectal probe or balloon linked to a manometric apparatus can be an effective treatment for childhood faecal retention associated with inappropriate external anal sphincter coordination (obstipation). We report an alternative biofeedback approach in a child with long-standing obstipation. Sphincter tone was detected by digitization instead of manometrically and information on the state of the muscle relayed orally, the child's mother acting as trainer and working at home. Five years of dependency on purgatives for bowel evacuation was reversed in three weeks of this regime. Carer-mediated biofeedback by digitization may prove a low-technology alternative to manometric methods where suitable equipment is unavailable.
