Currently, there is insufficient evidence to make conclusions regarding the efficacy and safety of biofeedback for patients with chronic constipation.
Further, well-designed randomised controlled trials are needed to allow definitive conclusions to be drawn.
Most patients with chronic constipation respond to conservative and pharmacological treatments. However, a minority of patients are refractory to treatment, one of the reasons being abnormalities of defaecation characterised by inability to relax the striated muscles which facilitate defaecation and/or ineffective defaecatory propulsive forces. Biofeedback, which employs instrumental learning through visual or auditory feedback using anorectal manometry or electromyography, has been recommended to improve muscle coordination in selected patients and …
