This study will involve the recruitment of symptomatic participants from a population that is representative of that for which the device is intended.\n\nThe primary objective of this study is the assessment of the agreement of Atmo Motility and SmartPill Systems' results with regards to both GET and CTT. The SmartPill is the accepted gold standard test for GI motility transit time analysis. Device agreement will be primarily examined through Bland-Altman analyses for GET and CTT measurements from the Atmo Motility and SmartPill Systems."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '80 Years', 'minimumAge': '22 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n1.
