About

A feasibility study for monitoring and recording gastrointestinal (GI) myoelectric activity in subjects with suspected or diagnosed irritable bowel syndrome (IBS) and reports of GI pain and asymptomatic subjects without IBS and GI pain.

Full description

This single arm, prospectively enrolling, non-randomized feasibility study has been designed to transcutaneously detect and monitor myoelectric intestinal signals temporally associated with the symptoms of patients who report pain and have suspected or diagnosed IBS, and in controls [subjects without suspected IBS or diagnosis of IBS and prior and/or current complaints of pain].

Enrollment: 88 patients

Sex: All

Ages: 18+ years old

Volunteers: Accepts Healthy Volunteers

Patients with and without FGIDs/IBS

Description:

Patients with functional gastro-intestinal disorders (FGIDs) undergo recording of myoelectric signals before, during, and after a meal. In addition, patients without FGIDs undergo recording of myoelectric signals before, during, and after a meal.
