Veterans with vestibular impairment have reduced quality of life, limitations on work and physical activities, and an increased risk of falls. The goal of this research is to develop a more engaging and effective interactive tool for vestibular rehabilitation to improve the lives of affected veterans. The first steps in this process will be to test the ability of the application to facilitate vestibular learning and to test its feasibility in vestibular patients. The hypothesis is that computer-game-based adaptation will induce robust VOR motor learning and will provide an engaging platform for vestibular rehabilitation. Ultimately, our application has the potential to provide more flexible vestibular exercises that will allow therapy to be customized for each patient. It will also have the ability to track a patient's progress over time and to advance exercises as function improves."}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '75 Years', 'minimumAge': '18 Years', 'samplingMethod': 'NON_PROBABILITY_SAMPLE', 'studyPopulation': 'Normal volunteers and patients with vestibular hypofunction', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* GROUP 1: Healthy volunteers: Static visual acuity of at least 20/30 at testing distance\n* GROUP 2: Vestibular patients: Unilateral or bilateral vestibular hypofunction, No central vestibular disorder, Static Visual Acuity of at least 20/30 at testing distance\n\nExclusion Criteria:\n\n* GROUP 1: Peripheral or central vestibular disorder\n* GROUP 2: Central vestibular disorder'}, 'identificationModule': {'nctId': 'NCT03589859', 'briefTitle': 'Computerized Vestibular Rehabilitation', 'organization': {'class': 'FED', 'fullName': 'VA Office of Research and Development'}, 'officialTitle': 'Computerized Game-based Vestibular Rehabilitation: Assessment of Feasibility and Motor Learning', 'orgStudyIdInfo': {'id': 'C2892-P'}}, 'armsInterventionsModule': {'armGroups': [{'label': 'Normal Volunteers', 'description': 'Testing motor learning', 'interventionNames': ['Diagnostic Test: VOR Test', 'Other: Computer Game']}, {'label': 'Vestibular hypofunction', 'description': 'Testing feasibility of rehabilitation game', 'interventionNames': ['Diagnostic Test: VOR Test', 'Other: Computer Game', 'Other: Nausea Scale']}], 'interventions': [{'name': 'VOR Test', 'type': 'DIAGNOSTIC_TEST', 'description': 'Video-oculography is used to record the vestibulo-ocular reflex during active and passive turns of the head.', 'armGroupLabels': ['Normal Volunteers', 'Vestibular hypofunction']}, {'name': 'Computer Game', 'type': 'OTHER', 'description': 'Participants play a custom computer game that is designed to produce motor learning in the vestibulo-ocular reflex', 'armGroupLabels': ['Normal Volunteers', 'Vestibular hypofunction']}, {'name': 'Nausea Scale', 'type': 'OTHER', 'description': 'Participants asked to rate their subjective nausea on a numeric scale after playing units of the computer game', 'armGroupLabels': ['Vestibular hypofunction']}]}, 'contactsLocationsModule': {'locations': [{'zip': '44106', 'city': 'Cleveland', 'state': 'Ohio', 'country': 'United States', 'facility': 'Louis Stokes VA Medical Center, Cleveland, OH', 'geoPoint': {'lat': 41.4995, 'lon': -81.69541}}], 'overallOfficials': [{'name': 'Mark F.
