Interacoustics TRV Chair

Unique chair for diagnosing and treating Benign Paroxysmal Positional Vertigo (BPPV).

Easy to diagnose
Diagnosing heavy patients, disabled patients, elderly patients or patients with a history of neck issues has always been a challenge when applying manual tests such as the Dix-Hallpike and Positional tests. Between 10 and 20% of patients with BPPV cannot be adequately diagnosed and treated with conventional methods.

Safe and secure
With the patient comfortably secured by a four-point harness, additional headrest, and foot support - the examiner can rotate the patient in any canal plane with 360 degrees of freedom around the vertical and horizontal axes.

Easy to operate
Due to the system with the adjustable counterweight, the weight of the chair and the patient are balanced, making it very easy to perform the maneuvers with little effort from the operator.

From diagnosis to treatment
The TRV chair is not only a diagnostic tool, but it is also an integral part of the rehabilitation process. In addition to the standard BPPV maneuvers (such as an Epley or Semont) there are unique new maneuvers (Dynamic maneuvers) to treat all types of BPPV in any of the 6 canals.

Innovative patented product
Thanks to its perfect balance, the TRV chair allows the examiner to easily rotate the patient 360 degrees along the plane of each semicircular canals (scc) and to hold the patient in any position for detailed examination of the semicircular canals. This facilitates stress-free and precise stimulation and diagnosis of any of the 6 semicircular canals. 



Vertigo, or dizziness, accounts for about 6 million clinic visits in the U.S. every year, and nearly 50% of these patients are eventually diagnosed with BPPV. BPPV represents the most common cause of otogenic vertigo. Nearly 10% of the population will experience an incidence of BBPV during their lifetime.

BPPV affects all ages but the incidence steadily increases by 38% per 10 years of life, with a peak incidence between 50 and 70 years.
