“We’ve been limited up until now because we’ve only been able to see a small fraction of the picture of what’s happening,” said Kristen Janky, AuD, PhD, director of the Clinical Vestibular Lab and coordinator of vestibular services at Boys Town National Research Hospital in Omaha, Neb. “We weren’t able to get a big picture of what’s going on in the balance center.”
The advent of video head impulse testing (vHIT) and vestibular evoked myogenic potential (VEMP) testing now allows researchers and clinicians to probe the function of all ten end organs, including the three semicircular canals and two otoliths on each side.
These tests open new possibilities to researchers, clinicians, and patients. They also invite debate and confusion as clinicians figure out how best to utilize these tools for the benefit of patients.
