Clinical Validation

**Home Vs Office*(1)**

●Total 100 subjects. 50 subjects for office and 50 subjects for home

●Effective: Home-based biofeedback therapy improved bowel symptoms associated with constipation and in correcting dyssynergic defecation in >65% of subjects.

●Viability: The home device was well tolerated without adverse events.

●COST: Home-based biofeedback therapy was significantly lower than that for office-based biofeedback therapy.

**Effective Treatment*(2)**

●Randomized trial, investigated the efficacy of biofeedback in 77 subjects (69 women) with chronic constipation and dyssynergic defacation.

●Conclusion: Biofeedback is the preferred treatment for constipated subjects with dyssynergia.

**Incontinence and DD*(3)**

●Randomized pilot study of 13 subjects- 7 had home devices and 6 had office devices

●Responder rates of >70% in home study; Quality of life improved in both groups

●Biofeedback therapy (BT) with BioAnatoner was effective as office BT in improving bowel function and Dysenergic Defacation.

● Bioanatoner could facilitate wider use of both anorectal BT for both Home and Office use.
