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.
Features
• 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.
• LCD TV
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.
