TRV Chair

TRV Chair – Vestibular Assessment & Rehabilitation System

The TRV Chair is a state-of-the-art vestibular diagnostic and rehabilitation system specially developed for the evaluation and treatment of Benign Paroxysmal Positional Vertigo (BPPV). It allows clinicians to perform controlled 360° patient rotation along the plane of each semicircular canal, enabling highly accurate positional testing and effective therapeutic maneuvers.

Key Features

• Advanced 360° rotational movement for precise stimulation of all semicircular canals
• Designed for comprehensive BPPV diagnosis and vestibular rehabilitation
• Compatible with the VisualEyes™ Video Frenzel system for real-time nystagmus monitoring
• Comfortable and secure design suitable for elderly, disabled, overweight, and cervical spine patients
• Supports multiple repositioning procedures including Epley, Semont, Dix-Hallpike, and Dynamic BBQ maneuvers
• Equipped with four-point safety harness, leg restraints, shoulder pads, and head support
• Hydraulic stop mechanism generates controlled kinetic energy to improve otoconia repositioning effectiveness
• Enables prolonged positional testing with enhanced patient comfort and reduced physical strain
• User-friendly clinical operation for audiologists, vestibular specialists, and ENT professionals
• Rechargeable magnetic lock battery system for added operational safety

Technical Specifications

• Dimensions: 160 cm × 120 cm × 190 cm
• Weight: Approximately 640 kg
• Operating Temperature: 5°C to 40°C
• Humidity Range: 30% to 90%
• Installation Requirement: Standard medical examination room setup

Clinical Advantages

The TRV Chair significantly enhances the success rate of BPPV treatment by delivering controlled kinetic energy during repositioning procedures. It is especially beneficial for patients who are unable to tolerate conventional bedside positional testing due to mobility limitations, neck disorders, or physical discomfort. The integrated eye-monitoring compatibility allows clinicians to observe fixation-free nystagmus in real time, improving diagnostic accuracy and treatment outcomes.
