Biofeedback in the treatment of faecal incontinence

Faecal incontinence is a distressing condition that affects approximately 1% of the population. Poor anal canal function can be determined by physiological testing using manometry and electromyographic techniques. Surgical repair of the anal canal does not always restore continence but biofeedback training either alone or in combination with other techniques such as muscle stimulation allows restoration of some degree of functional integrity of the anal canal musculature. Biofeedback training offers a non-surgical approach to incontinence with good success rates and prolonged after benefits. However, patient motivation is crucial as the exercise techniques taught need to be continued on a permanent basis if continence is to be maintained.
