An observational study in Vestibular Disease, sponsored by Aultman Health Foundation. Completed. Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2020-01-18.
Sponsored by Aultman Health Foundation · Observational
The purpose of this study is to explore the diagnostic values associated with both a positive and negative Skull Vibration Induced Nystagmus Test (SVINT) performed in room light (with fixation). The hypotheses include: 1. A positive room light SVINT will be identified in individuals with moderate to severe vestibular asymmetries. 2. A positive room light SVINT will be present when 10 beats or more (counted over 10 seconds) of nystagmus are found with fixation blocked.
Dizziness and vertigo account for about four million visits to the Emergency Department per year and costs for management in the Emergency Department are estimated to be about four billion dollars per year. Vestibular problems are a major cause of dizziness. Simple to perform and inexpensive bedside vestibular tests are needed. The Skull Vibration-Induced Nystagmus Test (SVINT) with fixation blocked has been considered a vestibular gold standard test with strong psychometric values. No studies on the diagnostic accuracy of the SVINT in room light have been performed.
172 studies on the registry are indexed under Vestibular Diseases; 41 are open to participants now.
This study's enrollment of 256 is above the median of 59 across 34 observational studies indexed under Vestibular Diseases.

Patients with complaints of dizziness, vertigo, and/or imbalance referred to the hospital outpatient physical therapy department.
Exclusion Criteria:
A standardized questionnaire used to quantify symptoms of dizziness.
A standardized questionnaire used to review the overall outcome of the participants condition with physical therapy.
A standardized questionnaire used to determine whether meaningful progress has been made
An observational test procedure used to identify involuntary eye movements caused by inner ear and/or brain dysfunction. The test is performed both in room light and with fixation blocked with a Micromedical Technologies infrared lens.
An observational test procedure used to identify involuntary eye movements caused by inner ear and/or brain dysfunction. The test is performed both in room light and with fixation blocked with a Micromedical Technologies infrared lens.
A test used to identify asymmetry that may be present in the vestibular system through 60-100 MHz vibration applied to the mastoid bone. A WAHL massager is used to stimulate the inner ear by vibrating the mastoid bone. The test is performed both in room light and with fixation blocked with a Micromedical Technologies infrared lens.
Primary Vibration Test
Under room light, the presence or absence of nystagmus is determined. If nystagmus is present, then the direction of nystagmus is determined. When fixation is blocked, the presence or absence of nystagmus is determined. If nystagmus is present, then the direction of nystagmus is determined. The number of beats per 10 sec is also determined.
