Helpfulness of the Vibration Test Performed in Room Light on Clients With Inner Ear Problems

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.
