The video head impulse test (v-HIT) can evaluate the function of all semicircular canals (SCCs) in a short period. In this work, we sought to compare v-HIT results among 2 commercially available devices, the ICS impulse (Otometrics, Denmark) (ICS) and Eye See Cam (Interacoustics, Denmark) (ESC), among individuals with unilateral vestibular disorders.

Discussion
Signed responses from readers of the wire.
Findings may refine how audiologists interpret vHIT canal-specific patterns in acute vestibular dysfunction, but full results are needed before adjusting diagnostic protocols.
A comprehensive canal-by-canal vHIT comparison in acute vestibular dysfunction could sharpen differential diagnosis between peripheral and central causes of sudden dizziness.
- 01Study compares vHIT results across all semicircular canals in acute vestibular dysfunction.
- 02vHIT is a standard clinical tool measuring the vestibulo-ocular reflex (eye-stabilizing inner-ear reflex).
- 03Canal-specific analysis may help distinguish vestibular neuritis, labyrinthitis, or other acute causes.
- 04Directly relevant to audiologists and ENTs managing acute dizziness presentations.
