Quantification of the vestibulo-ocular reflex for the purpose of clinical diagnostics is dependent upon measurements within that portion of the dynamic range which has a constant gain, independent of visual contamination. Head oscillation at about 3 Hz is characterized by unity gain irrespective of visual influence. At lower frequencies visual tracking dominates compensatory eye movements and fixation suppression of the VOR can be quantified precisely. The new test is based upon power spectral analysis of compensatory eye movements during rotatory stimulation on a powerful hydraulic rotation chair. There is evidence suggesting that this test can precisely quantify vestibular lesions and provide side detection of peripheral damage.
为临床诊断目的而对前庭眼反射进行量化，依赖于在动态范围内具有恒定增益且不受视觉干扰的那部分测量值。大约3Hz的头部摆动具有单位增益，与视觉影响无关。在较低频率时，视觉跟踪主导着代偿性眼球运动，并且可以精确量化前庭眼反射的注视抑制。这项新测试基于在强力液压旋转椅上进行旋转刺激时对代偿性眼球运动的功率谱分析。有证据表明，该测试可以精确量化前庭病变，并对周围损伤进行侧别检测。
