List of Clinical Applications

BPPV

BPPV

EquiCCG detects subtle postural instability in BPPV cases, even when Dix-Hallpike is negative, by revealing signs like Romberg positivity or directional drift, guiding further vestibular evaluation.

Vestibular neuritis/labyrinthitis

Vestibular neuritis/labyrinthitis

EquiCCG identifies postural instability and directional drift through objective balance tests like Romberg and Unterberger, aiding early detection of vestibular neuritis even when other signs are subtle.

Ménière’s Disease

Ménière’s Disease

EquiCCG provides objective balance metrics that serve as baseline and follow-up records for tracking postural changes before and after treatments like intratympanic gentamicin in Ménière’s disease. 

Evaluating balance

Evaluating balance

Evaluating balance disorders in conditions like stroke, Parkinson's disease, cerebellar ataxias, and multiple sclerosis.

Balance Dysfunction

Balance Dysfunction

Differentiate between peripheral and central causes of vertigo and balance dysfunction.

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.
