TRV Chair

Perfect balance for three-dimensional movement

The TRV Chair is designed for diagnosis and treatment of Benign Paroxysmal Positional Vertigo (BPPV). Thanks to its perfect balance the TRV Chair allows the examiner to move the patient in three-dimensional movements and to hold the patient in any position for detailed examination of any area of the vestibular system.

Designed for diagnosis and treatment

The patient is secured by a four-point harness, a leg strap, shoulder pads and a head mount, and the eye movements are transmitted to a monitor by means of a goggle with infrared video cameras.

With the patient comfortably secured, the examiner is free to rotate the patient in full circles around the vertical and horizontal axes.

Thanks to its perfect balance the TRV chair allows the examiner to move the patient in three-dimensional movements and to hold the patient in any position detailed examination of any area of the vestibular system. This facilitates stress-free and precise stimulation and diagnosis of any of the 6 semicircular canals.

Includes traditional maneuvers

With the TRV Chair the effectiveness of these maneuvers can be enhanced by adding kinetic energy to the liberatory maneuver. The kinetic energy will accelerate the movement of the smaller otoconia that would otherwise remain in their original location. This is often the only way to treat patients with few and weak positional nystagmus despite strong symptoms.

The kinetic energy is added by driving the main arm of the TRV Chair against a hydraulic stop in each sequence in the liberatory maneuver; this produces a mild deceleration which is sufficient to free even the smallest otoconia and secure a successful treatment.
