Interacoustics Nydiag 200 BrochureMicromedical Technologies System 2000
 | 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. 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. A focused solid state laser with galvonometer produces pinpoint stimulus for gaze, pursuit, saccade, and VOR with fixation tests. An Optokinetic Drum is ceiling mounted for OKN and VOR with vision tests. |
