Product Features

3D eye + head tracking

3D eye + head tracking

3D eye + head tracking

Simultaneously records head and eye movements in real time, ensuring precise head–eye correlation. 

Torsional nystagmus quantification

Torsional nystagmus quantification

Torsional nystagmus quantification

Accurately measures torsional eye rotations, adding diagnostic precision for complex vertigo.

120 fps dual-eye IR cameras

120 fps dual-eye IR cameras

120 fps dual-eye IR cameras

High-speed infrared cameras capture subtle nystagmus, with slow-motion replay for clarity.

Video Frenzel mode

Video Frenzel mode

The goggles block the patient’s vision while a magnified live video of their eyes is shown to the clinician. This allows spontaneous or positional nystagmus to appear without fixation suppression, just like Frenzel lenses. 

Guided workflows with on-screen prompts & head-angle feedback

Guided workflows with on-screen prompts & head-angle feedback

Provides step-by-step prompts with real-time head angle confirmation for error-free testing. 

Configurable positional protocols

Configurable positional protocols

List of Clinical Applications

BPPV

BPPV

EquifHIT typically shows normal HIT, helping differentiate BPPV from VOR-related disorders; rare canal paresis may mimic neuritis. 

Vestibular neuritis/labyrinthitis

Vestibular neuritis/labyrinthitis

EquifHIT detects unilateral VOR failure via corrective saccades during head impulses; key for diagnosing neuritis or labyrinthitis.

Ménière’s Disease

Ménière’s Disease

EquifHIT may reveal transient VOR deficits during attacks, aiding in episodic vertigo evaluation when symptoms fluctuate.

Superior Canal Dehiscence

Superior Canal Dehiscence

EquifHIT shows normal or hyperactive VOR in low-frequency HIT, supporting the diagnosis of sound/pressure-induced vertigo.

Brainstem/Cerebellar Strokes

Brainstem/Cerebellar Strokes

EquifHIT helps distinguish central vs. peripheral vertigo; normal HIT in PICA stroke, possible HIT+ in AICA due to labyrinth involvement.

Traditional balance assessments offered only a limited view of patient conditions. With EquiCOG and Equipoise from the Equidor range by Taevas, our diagnostic precision has transformed. EquiCOG helps detect even minute balance deficits across somatosensory, central, and peripheral systems, while Equipoise enhances posturography accuracy and treatment planning. The entire installation and support experience with the Taevas team was seamless.
