With Micromedical Technologies System 2000 Rotational Vestibular Chair, the Vestibular Ocular Reflex (VOR) can be measured from 0.01 to 1.28 Hz at velocities up to 300 degrees/second.

With the System 2000 chair, the clinician is able to perform VOR, Visual Vestibulo Ocular Reflex (VVOR), Visual Fixation (VFX), Optokinetic After Nystagmus (OKAN), Velocity Step, and Subjective Visual Vertical tests in addition to the standard ocularmotor test battery.

System 2000 chairs now function in Windows® XP!

Features:

• Advanced Chair Design
  Micromedical Technologies' System 2000 accurately accelerates and changes direction without inertial artifact. The torque motor in the base of the chair is engineered to provide quiet, precisely controlled rotation.

• Laser Projector
  A focused solid state laser with galvonometer produces pinpoint stimulus for gaze, pursuit, saccade, and VOR with fixation tests.

• Optokinetic Drum
  This highly accurate servo-motor driven projector is ceiling mounted for OKN and VOR with vision tests.

• Video Eye Tracking
  Utilizing VisualEyes on the rotational chair increases the ease and accuracy of eye movement recording. VisualEyes see-through provides a full field of view and refines the diagnostic process by eliminating biological artifacts and allowing eye movements to be recorded and analyzed objectively as well as subjectively from one or both eyes.

• Enclosure
  The fully enclosed six-foot diameter booth ensures a light-tight environment for reliable VOR testing.

• Infrared Video Camera
  Monitor patient alertness with this chair-mounted infrared video camera.

• Micro-Centrifuge and Subjective Visual Vertical Option

  This enhanced System 2000 rotational chair has the ability to precisely position patient’s right or left otolith organs over the axis of rotation. When rotating off yaw axis, centripetal acceleration stimulates the otolith organs resulting in a perception of tilt by subject. This tilt can be recorded by a pointer that is rotated by the subject until the subject perceives that it is visually vertical. This phenomena is also known as Subjective Visual Vertical (SVV). Impaired otolith function on one side may results in both a static and a dynamic shift in SVV.
