TRV Chair

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

Interacoustics vHIT EyeSeeCam

Orion Reclining

Micromedical by Interacoustics Orion Reclining

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.
