EquifHIT: Vestibulo-ocular reflex (VOR) testing device with cutting-edge technology

FHIT

EquifHIT is an advanced, non-invasive diagnostic Vestibulo-Ocular Reflex (VOR) testing device, the mechanism that stabilizes vision during head movements. By analyzing eye responses to rapid head impulses, EquifHIT assesses the function of the semicircular canals, helping detect vestibular abnormalities. It delivers critical insights for patients experiencing dizziness, imbalance, and vertigo, empowering clinicians with precision and clarity.

Test Protocols

EquifHIT conducts precise analysis of all six semicircular canals using rapid head impulses. Its comprehensive protocols ensure accurate vestibular evaluation across all planes of motion.

Assessment of Right & Left Horizontal Canal

Assessment of Right & Left Horizontal Canal

  • 30° forward head tilt
  • Align the horizontal canal and sensor
  • Turn head at 45 degrees
  • Smooth Movement
  • Green Zone Velocity
  • Identify the alphabet
  • Record the response
Assessment of Right and Left Anterior Canal

Assessment of Right and Left Anterior Canal

  • Right and left anterior canals
  • Head turned at 45 degrees
  • Head movement: upwards and then downwards
  • Record the response
Assessment of Right and Left Posterior Canal

Assessment of Right and Left Posterior Canal

  • Right and left posterior canals
  • Head turned at 45 degrees
  • Head movement: downwards and then upwards.
  • Record the response

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.

Multiple Sclerosis (MS)

Multiple Sclerosis (MS)

EquifHIT may show perverted or irregular saccades, indicating central VOR disruption from demyelination. 

Neurodegenerative Disorders (Spinocerebellar Ataxia)

Neurodegenerative Disorders (Spinocerebellar Ataxia)

EquifHIT reveals bilateral VOR deficits with cerebellar signs, supporting the diagnosis of progressive vestibular dysfunction. 

Bilateral Vestibular Loss (BVL)

Bilateral Vestibular Loss (BVL)

EquifHIT identifies corrective saccades in both directions and low VOR gain, confirming bilateral vestibular hypofunction.

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.
