Video Head Impulse Testing (vHIT): A Deep Dive

In this presentation, Dr. Kamran Barin, Ph.D, will discuss video head impulse testing (vHIT).
This talk will cover the pathophysiology of vHIT, test parameters for performing vHIT as well as interpretation of the results with consideration of the impact of artifacts, and the clinical application of vHIT.
