Vestibular Balance Testing - System 2000
Features • Advanced Chair Design The System 2000 Rotational Vestibular Chair 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 (VNG) 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 enhancement for the System 2000 Rotational Vestibular 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.
