Detailed Description:

This single-arm, 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].
