Enrollment: 88
Study Start Date: July 2012
Study Completion Date: June 2015
Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)
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].

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Sampling Method:   Non-Probability Sample
Study Population
Irritable bowel syndrome, functional bowel disorder.

General Eligibility Criteria:

  • No known allergy to commercially available food or drink required by specified study procedure regimen;
  • Willing and able to recline and remain still during the recordings.

General Exclusion Criteria
