Biofeedback therapy (BFT) is the most effective conservative treatment, teaching patients to coordinate abdominal and anal muscles during defecation. In standard practice, the rectal balloon used in high-resolution anorectal manometry (HRAM) and biofeedback is left deflated, though some centres inflate it to simulate a more natural urge to defecate.\n\nHowever, the efficacy of this modification has not been validated. This study aims to determine whether performing BFT with the balloon inflated to a patient's defecatory desire volume enhances physiological coordination and patient understanding compared to the standard deflated approach.",[26,27,28,29],"Constipation","Chronic Constipation","Dyssynergia","Anismus",[31],"biofeedback","RECRUITING","2026-07-13",{"date":35,"type":36},"2026-07-15","ACTUAL",{"date":38,"type":36},"2026-05-13",{"date":40,"type":20},"2026-07",{"name":42,"class":43},"Hull University Teaching Hospitals NHS Trust","OTHER_GOV"]
