Balance Quest by Interacoustics TRV Chair

BPPV treatment made comfortable.

The TRV Chair is a unique tool for the diagnosis and treatment of benign paroxysmal positional vertigo (BPPV).  The the TRV Chair, examiners can rotate their patients 360 degrees along the plane of each semicircular canal.  It is possible to lock the patient in any position for a detailed look at each semicircular canal.

Why is the TRV Chair an important tool in benign paroxysmal positional vertigo (BPPV) patients?

Benign paroxysmal positional vertigo (BPPV) is the most common cause of otogenic vertigo. However, positional testing can be difficult or impossible with certain patient groups. This includes patients that are heavy, disabled, elderly or who have neck issues. Thus, a large portion of BPPV patients cannot be treated with conventional methods.

How to perform BPPV treatment with the TRV Chair

Precise stimulation and diagnosis of all six of the fluid-filled semicircular canals

Micromedical by Interacoustics vHIT - EyeSeeCam

Features: ~~The EyeSeeCam vHIT provides quick and objective measurements of the vestibular-ocular reflex (VOR). A simple tool to assess the performance of all 6 semicircular canals. The results allow the healthcare professional to efficiently diagnose the “dizzy” patient and evaluate if the dizziness is related to a vestibular disorder.

Micromedical by Interacoustics Visual Eyes 505 Binocular Video Frenzel System

Features include: Ability to display both eye and situation camera images on the screen, Recording indicator with elapsed time, Pre-labeled tests or create your own test names, Remote controlled video recording and fixation light with optional handheld remote, or goggle button. Video files are stored in AVI file format.

Playback in slow motion or frame by frame - Crosshairs displayed during playback - Time line scrolls to show location in raw data - Videos are stored in a easily accessible folder

Micromedical by Interacoustics Orion Auto-Traverse

Rotational chair with off-axis centripetal acceleration.

The Auto-Traverse chair is a state-of-the-art enclosed rotary chair, engineered to deliver precisely controlled stimuli and superior data analysis of the VOR. The innovative Auto-Traverse chair offers maximum acceleration up to 200 deg/sec and can accommodate for patient weight up to 400 lbs.

The Comprehensive test battery provides the clinician with advanced protocols which can be customized to meet the needs of the patient population from infants to adults:

Sinusoidal Harmonic Acceleration (SHA) from 0.01 Hz to 1.28 Hz, Step Velocity Test up to 350 deg/sec, VOR Suppression Test from 0.01 Hz to 1.28 Hz with built-in laser fixation target, Visual VOR Test utilizing the built-in optokinetic drum to enhance the VOR, Static and Dynamic subjective visual vertical (SVV) tests. The off-axis centripetal acceleration offered with the Auto-Traverse chair provides for advanced dynamic assessment of eccentric otolith function with dynamic subjective visual vertical (SVV) test of perceived tilt: 300 deg/sec velocity on or off axis.

Micromedical by Interacoustics Orion Comprehensive

Providing insight into the complexity of the balance system.

The Comprehensive chair provides the same state-of-the-art features as the Auto-Traverse chair, but without the off-axis centripetal option.

Accommodating for a wide variety of vestibular assessment needs, the Comprehensive chair has a maximum velocity up to 350 deg/sec, maximum acceleration up to 299 deg/sec, and provides the clinician with advanced protocol options and customization.

The Test battery includes: Sinusoidal Harmonic Acceleration (SHA) from 0.01 Hz to 1.28 Hz, Step Velocity Test up to 350 deg/sec, VOR Suppression Test from 0.01 Hz to 1.28 Hz with built-in laser fixation target, Visual VOR Test utilizing the built-in optokinetic drum to enhance the VOR, Static subjective visual vertical (SVV) test. Note: for dynamic SVV, see the Auto-Traverse chair. The comprehensive chair is also ideal for clinics doing extensive pediatric assessments.

Combining Rotary Chair Testing with VNG

The Orion Reclining chair is a unique and space-saving solution with the practitioner in mind. With no booth enclosure, the chair can be reclined to varying positions, allowing the clinician to perform the entire VNG test battery from the rotational chair, with no need to move the patient to another exam table or separate room. This system utilizes the same VisualEyes 525 software that the standalone VNG system does, as do the other two Rotary Chairs.
The Test battery includes: Sinusoidal Harmonic Acceleration (SHA) from 0.01 Hz to 0.64 Hz, Step Velocity Test up to 200 deg/sec, VOR Suppression Test from 0.01 Hz to 0.64 Hz, Visual VOR using the included Large-Screen Monitor, All Oculomotor tests: Gaze, Smooth Pursuit, Saccades, Saccadometry and Optokinetics, Positional and Dix-Hallpike tests and Caloric evaluation. There is an angle gauge which helps you recline the chair to precisely 30 degrees for accurate caloric testing and to supine position for positional tests. The easy-to-remove headrest makes it ideal solution for Dix-Hallpike evaluation.
