The System 2000 Reclining Rotational Vestibular Chair can measure Vestibular-Ocular Reflex (VOR) from 0.01 to 0.64 Hz at velocities up to 200 degrees/second. The clinician can perform Visual Vestibulo-ocular Reflex (VVOR), Visual Fixation (VFX), and Velocity Step tests in addition to the standard ocular-motor testing. When reclined, the clinician can perform the Dix-Hallpike and Positional tests with the added benefit of completing caloric testing.


Advanced Chair Design
The System 2000 Reclining Rotational Vestibular Chair accurately accelerates and changes direction without inertial artifact. The torque motor is engineered to provide quiet, precisely controlled rotation.

Ocularmotor and gaze tests utilize a 32" LCD TV for the stimulus target. The television provides horizontal and vertical target displays as well as a full-field stimulus for optokinetic testing. The TV can be mounted to the wall and easily positioned to accommodate patient height differences.

Video Eye Tracking
Our FireWire Binocular Goggles increases the ease and accuracy of eye movement recording, providing a full field of view, and can block out ambient light when the cover is in place. The goggles have built-in fixation lights controlled by the software. Side mounted lights are used to remind the operator which ear is selected to be irrigated in caloric tests.

Ocularmotor Testing
The patient follows the target presented on the LCD TV. During optokinetic tests the software will display a full field of spheres for the patient to track. The target image can be customized for use in pediatric testing.

Caloric Testing
When the chair is reclined to 30° from vertical, the operator can perform caloric testing. Spectrum software integrates either the Micromedical Air Fx air caloric irrigator or AquaStim water caloric irrigator for computer controlled caloric stimulations.

Dix-Hallpike / Positional Testing
Recline the chair and remove the head rest to complete the Dix-Hallpike and Positional tests. The reclining chair also facilitates Canalith Repositioning maneuvers.
