VertiChair™ Product Overview

VertiChair™ is a fully motorized diagnostic and therapeutic chair system designed by ZEHNIT Medical Technology for comprehensive evaluation and treatment of vestibular disorders. It integrates rotary chair testing and BPPV diagnosis & treatment into a single, unified platform, streamlining clinical workflows and expanding diagnostic and therapeutic capabilities.

Core Features

• All-In-One Vestibular Solution
  VertiChair™ combines motorized rotary chair testing with standardized BPPV repositioning maneuvers, eliminating the need for separate devices and allowing clinicians to perform both diagnostic and therapeutic procedures within one system.

• Fully Motorized 360° Control
  The chair offers software-controlled 360° rotation and precise positioning at any angle, with customizable protocols for rotation speed, acceleration, and target angles to match specific clinical needs.

• Integrated Real-Time Eye Tracking
  When paired with VertiGoggles™, VertiChair™ supports synchronized 3D eye movement tracking — including horizontal, vertical, and torsional components — enabling objective measurement of vestibular responses such as slow-phase velocity (SPV).

• Ergonomic & Safe Design
  Equipped with adjustable headrest and safety harnesses, the system ensures secure and anatomically accurate patient positioning for both testing and treatment, improving comfort and diagnostic accuracy.

• Optional Advanced Modules
  – Off-Axis Centrifugation (ZT-CHAIR-I model) for selective otolith organ evaluation.
  – AI-Assisted BPPV Diagnosis & Treatment with VertiAI™ (research use; availability varies by region), offering intelligent classification and automated therapy workflows.

Supported Tests & Protocols

VertiChair™ supports a broad spectrum of vestibular diagnostic and therapeutic protocols, including:

• BPPV diagnosis & repositioning

• Rotary chair tests such as Sinusoidal Harmonic Acceleration (SHA), Velocity Step Test (VST), Impulse Acceleration, Constant Acceleration, Visually Enhanced VOR (VVOR), and VOR Suppression (VORS)

• Unilateral centrifugation tests for detailed otolith function assessment (optional in select models)

Ideal Clinical Use Cases

VertiChair™ is designed for use in:

• Vestibular and balance clinics

• ENT and neurology departments

• Rehabilitation centers

• Research and specialty diagnostic labs

By integrating motorized chair control, real-time eye tracking, and flexible protocols, VertiChair™ enables clinicians to perform comprehensive vestibular assessments and therapies with high precision, safety, and efficiency.
