Fecobionics in Biofeedback Therapy in Dyssynergia Patients

This study aims to monitor and predict biofeedback therapy based on mechanism-based and highly integrated data using a new medical device. This study is specifically for patients with dyssynergia before, during, and after biofeedback therapy. The balloon-like Fecobionics device (10 cm long and 1 cm in diameter) will be inserted into the participant's rectum and will record data before and during the expulsion of the device. The participant will be asked to do different motions like cough, squeeze, or push during the procedure. The novel data obtained in this study may help the investigators to identify the patients who will benefit or not benefit from biofeedback therapy before the therapy is done. This will determine the effectiveness of treatments for anorectal disorders.
