FUNCTIONAL DIAGNOSTICS GASTROINTESTINAL What is Biofeedback? q Provides the patient immediate Auditory and/or Visual information about Physiological Process q It's a Therapy, i.e. type of treatment where people are trained to improve their health by using Signals from their own bodies q By watching the monitor and listening to the sound the patient gets the Feedback information and can adjust thinking and behavior. Improve q The Goal in Lower GI is to Improve Pelvic Floor Dysfunction by teaching patients to change physiologic responses

FUNCTIONAL DIAGNOSTICS GASTROINTESTINAL Biofeedback in Lower GI Sphincter EMG Abdominal Pressure q Voluntary Sphincter contractions are recorded. Abdominal pressure as well q Feedback sent to patient (display and/or sound) q Patient actions: To increase sphincter contraction To decrease abdominal pressure Motor Internal Sphincter S2 S3 S4 External Sphincter Efferent

FUNCTIONAL DIAGNOSTICS GASTROINTESTINAL Patient Selection Process q Evaluate patient - diagnostic tests: AFT/ others q Diagnose patient Incontinence Constipation Others q Evaluate whether this patient would benefit from Biofeedback

FUNCTIONAL DIAGNOSTICS GASTROINTESTINAL Pathologies Incontinence Stress Fecal Incontinence due to: q Weak external Sphincter q Dyssynergia IS/ES to Rectum q Pelvic Floor Muscles Dysfunction Constipation q Due to Anismus Non-Neurogenic Origin

FUNCTIONAL DIAGNOSTICS GASTROINTESTINAL Biofeedback Process q Perform first biofeedback training in clinic q Help patient train at home q Perform biofeedback assessment in clinic to evaluate progress Change difficulty level q More home training q Etc...
