The rehabilitation of patients with benign paroxysmal positional vertigo (BPPV) commonly involves maneuvers such as the Epley and Semont maneuvers. By adding kinetic energy to these maneuvers, the TRV Chair can cure the dizzy patient.
The TRV Chair's ability to transmit kinetic energy is a powerful tool in the canalith repositioning procedure. Kinetic energy will accelerate the movement of free-floating calcium-carbonate crystals, also known as otoconia. Dizziness or vertigo are often the symptoms of wrongly-located otoconia within the inner ear. Kinetic energy is thus often the only feasible treatment for patients with canalithiasis, who experience positioning-related nystagmus due to wrongly-located otoconia.
The kinetic energy is added by driving the main arm of the TRV Chair against a hydraulic stop. This produces a mild deceleration, which relocates even the smallest otoconia, thereby securing a successful treatment.
The 360-degree rotation allows for each semicircular canal to be stimulated individually and in its extreme position. This provides optimal diagnostic value and allows for reliable and repeatable maneuvers. Using a chair for positional maneuvers rather than traditional bedside methods also allows for prolonged testing, without patient discomfort.
As the patient is securely and comfortably locked into position, treatment is available for all patient groups with the TRV Chair. Prior, patients with neck conditions and elderly, heavy or physically disabled patients were unsuitable for positioning maneuvers. This rendered a large group of patients without a means to treat their dizziness or vertigo.
The integrated VisualEyes™ Video Frenzel system enables the clinician to observe fixation-free nystagmus with great detail. The eye movements are displayed on a large screen for a good visual of positioning-related nystagmus.
