VertiSVV™ Product Overview

VertiSVV™ is a compact and intuitive system developed by ZEHNIT Medical Technology for conducting Subjective Visual Vertical (SVV) and Subjective Visual Horizontal (SVH) assessments that help evaluate otolith (gravity-sensing) function and central vestibular disorders in both upright and tilted head positions.

Key Features

• Dedicated SVV/SVH Testing System
  Provides a specialized diagnostic solution for measuring how patients perceive vertical and horizontal orientation, which is crucial for assessing otolith organ function and central sensory integration.

• Immersive Visual Environment
  Uses virtual-reality goggles to eliminate external visual references, ensuring accurate and controlled testing conditions without visual distractions.

• Dual Stimulus Modes
  Offers two selectable visual target presentations to fit different clinical protocols and accommodate individual patient needs.

• Wireless Controller with High Precision
  An ergonomic, one-hand wireless controller allows clinicians or patients to align the visual target smoothly, with measurement accuracy to within ±0.2°.

• Real-Time Feedback & Tracking
  The system displays head orientation and target position simultaneously, giving clinicians immediate visual feedback to monitor patient alignment and performance during testing.

• Seamless Software Integration
  VertiSVV™ connects wirelessly to VertiPACS™, ZEHNIT’s all-in-one clinical software platform, allowing centralized management of test data and streamlined workflow across vestibular assessments.

Clinical Value

VertiSVV™ empowers clinicians to perform objective and reproducible SVV/SVH tests, supporting the diagnosis and monitoring of vestibular disorders involving otolith dysfunction or central sensory deficits. Its immersive design, precision measurement, and integration with unified software make it suitable for balance clinics, ENT/neurology departments, and vestibular research settings.
