本文用自制电动转椅,以60～180°/s角速度急停刺激,在131名健康飞行人员身上研究了旋转后眼震电图特性,并得出了常值。各种参数均经Z—80微型计算机处理。 旋转后眼震电图特性:平均慢相角速度以时间为自变量呈指数函数衰减,随刺激量增大呈线性增加;眼震时间和次数与刺激强度间无线性关系;后相眼震出现率随刺激强度增大而增高。实验认为, 做旋转后眼震电图的适宜刺激为60,90°/s急停;分析指标为眼震时间、总次数、3～12秒内的眼震次数、平均慢相角速度和后相眼震。 检查了69名前庭功能水平不同的病人。经判别分析方法检验,符合率为66.7～90.0％。
In this paper, a self-made electric swivel chair, with 60 ~ 180 ° / s angular velocity emergency stop stimulation, 131 healthy flight personnel who studied the rotation of the ocular electrogram characteristics, and come to constant. Various parameters are Z-80 microcomputer processing. The characteristics of rotational post-ocular electrogram: The average slow phase angular velocity decay exponentially with time as an independent variable and linearly increase with the increase of the stimulus amount; there is no linear relationship between the nystagmus time and frequency and the stimulus intensity; With the stimulation intensity increases. The experimental results show that the appropriate stimulation for the rotation of the oculography is 60,90 ° / s; the analysis indexes are nystagmus time, the total number of times, the number of nystagmus in 3 ~ 12 seconds, the average slow phase angular velocity and the posterior phase Nystagmus. 69 patients with different levels of vestibular function were examined. Discriminant analysis showed that the coincidence rate was 66.7 ~ 90.0%.
