17 Efficacy of biofeedback therapy Symptomatic improvement has varied between 44% up to 100% in several uncontrolled trials (Heymen et al 2003) Studies in adults suggest biofeedback to be effective in 70% of patients with long term benefits (Norton 2008) Last few years there have been several randomised controlled trials (Chiaironi et al 2006, Rao et al 2008, Heymen et al 2007, Rao et al 2010) Significant differences in methods, in end points and outcomes. However all concluded biofeedback therapy to be superior to controlled treatment approaches. Cochrane review 2012 also concluded that biofeedback therapy was of more benefit than other interventions and instruments Nice guidance for faecal incontinence and IBS.
