Unique chair for diagnosing and treating Benign Paroxysmal Positional Vertigo (BPPV).
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.
The rehabilitation of patients with BPPV commonly involves traditional maneuvers such as the Epley, Semont, Gufoni, Appiani and similar.
With the TRV chair the effectiveness of these maneuvers can be enhanced by following the exact plane of the canal, and 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 residual lateral canalithiasis linked to a very few otoliths in the canal resulting in a weaker 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 de-acceleration which is sufficient to free even the smallest otoconia and secure a successful treatment.
Kinetic energy is also applied in the Dynamic BBQ Maneuver (DBM). DBM is a series of 2 x 7 rotations around
the vertical axis with shifts between acceleration and deceleration; a highly effective treatment of lateral canal BPPV.
