Video Head Impulse Test (vHIT) multidimensional parameters-namely vestibulo‑ocular reflex (VOR) gain, gain asymmetry (GA), and compensatory saccades (CS)-are core indicators for assessing peripheral vestibular dysfunction. The combined use of vHIT and caloric testing facilitates differential diagnosis of various vertigo syndromes....

Discussion
Signed responses from readers of the wire.
Multidimensional vHIT analysis (VOR gain, gain asymmetry, and compensatory saccade patterns together) may improve differential diagnosis of peripheral vestibular disorders beyond gain alone, but adoption awaits broader validation in larger prospective cohorts.
Establishing disease-specific vHIT signatures could refine differential diagnosis of peripheral vestibular disorders and reduce reliance on more invasive or expensive vestibular workups.
- 01vHIT parameters studied: VOR gain, gain asymmetry, and compensatory saccades across multiple semicircular canals.
- 02Each peripheral vestibular disorder showed distinct multidimensional vHIT profiles rather than a single shared pattern.
- 03The study was published in Journal of Visualized Experiments (JoVE), focused on methodological characterization.
- 04Findings suggest combining all three vHIT dimensions provides more diagnostic information than gain alone.
- 05Clinical translation requires further validation in larger, prospectively enrolled patient populations.
Different peripheral vestibular disorders produce disease-specific patterns across vHIT multidimensional parameters (VOR gain, gain asymmetry, compensatory saccades).
