Biofeedback training for patients with myelomeningocele and fecal incontinence

This study evaluated the efficacy of biofeedback training for fecal in continence in patients with myelomeningocele. 12 patients were randomized to receive conventional treatment alone, or in conjunction with biofeedback. Anorectal manometric functions were evaluated before and after treatment, six and 12 months later. 16 control children were also studied. Three of eight patients in the biofeedback group and three of the four given conventional treatment alone reported greater than or equal to 75 per cent improvement in frequency of soiling 12 months later. Biofeedback training did not improve anal squeeze, rectal sensation or continence of rectal infused saline. The number of patients who improved in both treatment groups was not different.
