VertiChair™ integrates BPPV repositioning maneuvers and rotary chair testing into a single motorized system. This eliminates the need for multiple devices, streamlines clinical workflow, and expands both diagnostic and therapeutic capabilities in one unified solution.

All chair movements are electrically driven and precisely controlled via software—no manual rotation required. The system supports continuous 360° rotation and angle locking at any position. Clinicians can select from built-in standardized protocols or customize key parameters such as rotation speed, target angle, and acceleration to meet specific diagnostic or therapeutic needs.

Paired with VertiGoggles™, the system enables real-time three-dimensional eye movement tracking—including horizontal, vertical, and torsional components—during BPPV maneuvers. Built-in calibration functions support accurate measurement of slow-phase velocity (SPV), allowing clinicians to assess vestibular function quantitatively and objectively.

Equipped with adjustable safety harnesses and a fully adjustable headrest, VertiChair™ accommodates patients of different body types while ensuring secure and anatomically correct head positioning throughout testing and treatment. This design enhances patient safety, improves diagnostic accuracy, and increases the success rate of BPPV repositioning maneuvers.

This module supports lateral displacement from the central axis to generate off-axis centripetal acceleration, enabling unilateral centrifugation for selective otolith organ stimulation. It supports both UCF-SVV (Unilateral Centrifugation Subjective Visual Vertical, with VertiSVV™) and UCF-OCR (Unilateral Centrifugation Ocular Counter-Roll, with torsional eye movement tracking), providing deeper diagnostic insights into otolith function—particularly in cases involving unilateral deficits or central compensation.

VertiAI™ is an intelligent diagnostic module that assists in determining whether a patient has BPPV, and if so, automatically classifies it into one of six subtypes based on recorded eye movement and head position data. Once diagnosed, clinicians can immediately initiate standardized or customized repositioning protocols on the VertiChair™-all while the patient remains seated. With just a few clicks, VertiAI™ reduces diagnostic complexity, minimizes the risk of misdiagnosis, and enhances clinical efficiency, delivering faster, more consistent, and patient-friendly BPPV care.
