对12名正常人、2名迷路功能丧失者用日常很少经历的大幅度、高频率摆动行凝视功能检查。旋转传感器记录头动、ENG记录眼动。受试者在暗室熟悉前面红灯15分钟后凝视定标、头动、眼动和凝视20°时相当记录纸8mm。开始低频大幅度(0.5～1.0Hz,±20～25°),后加速度。使患者连续大幅度头摆动15～20秒,休息30～60秒后重复几次,直到取得稳定的记录。随转动频率加大头转动平均总幅度下降,正常人高频大幅度摆动时,眼动幅度大于头幅,故两者比值升高。高频时受试者视觉模糊,感红灯左右摆动,凝视记录的波动系头部
Twelve normal subjects and two lost functioners were examined by staring at high frequency and high frequency with little daily experience. Rotary sensor recording head movement, ENG record eye movements. Subjects in the darkroom familiar with the red light in front of 15 minutes after the gaze calibration, head movements, eye movements and gaze 20 ° when the recording paper 8mm. Start low-frequency significantly (0.5 ~ 1.0Hz, ± 20 ~ 25 °), after the acceleration. So that patients with substantial head swing for 15 to 20 seconds, rest 30 to 60 seconds after repeated several times until a stable record. As the rotation frequency increases, the average total rotation amplitude decreases. When the normal person swings at a high frequency, the eye movement amplitude is greater than the head amplitude, so the ratio of the two increases. Subjects at high frequency blurred vision, red light around the swing, gaze records of the Department of head fluctuations
