摘　　要：目的通过观察前庭刺激后受试者血压(BP)、心率(HR)、心率变异性(HRV)及认知能力等的变化,为建立飞行人员前庭性错觉模拟体验训练方案提供实验依据。方法20名健康青年男性受试者利用前庭性错觉模拟训练系统进行前庭刺激训练,持续时间3 min,其中加速阶段持续50 s,匀速旋转复合转头阶段持续2 min,减速阶段持续10 s。记录受试者训练后HR、BP、HRV、认知功能评分、局部脑氧饱和度(rSO2)、前庭症状变化及错觉发生情况。结果与实验前相比,前庭刺激过程中受试者舒张压(DBP)、HR与呼吸频率(RR)均显著升高(P<0.05);前庭刺激后受试者注意力分配任务中神经行为能力指数(NAI)显著下降(P<0.05),前庭症状评分显著增加(P<0.05),前庭功能稳定性分级为:0度4人,I度16人,Ⅱ度0人,Ⅲ度0人,前庭性错觉诱发率100%。结论利用前庭性错觉模拟训练系统对受试者进行前庭刺激可引起适度的前庭反应,诱发前庭性错觉,对心血管功能和分配性注意力有一定影响。本研究为飞行员前庭性错觉模拟体验训练方案的制定提供了参考。AIM To observe the changes of BP,HR,HRV and cognitive ability of the subjects after vestibular stimulation,so as to provide experimental basis for establishing the training program of pilots’vestibular illusion simulation experience.METHODS Twenty healthy young male subjects were trained by vestibular illusion simulation training system for 3 minutes,in which the acceleration phase lasted for 50 seconds,the uniform rotation compound turning phase lasted for 2 minutes,and the deceleration phase lasted for 10 seconds.HR,BP,HRV,cognitive function score,SO2,vestibular symptoms and illusion were recorded after training.RESULTS Compared with those before the experiment,DBP,HR and R of the subjects during vestibular stimulation were significantly increased(P<0.05).After vestibular stimulation,NAI in the task of attention allocation of subjects decreased significantly(P<0.05),and the vestibular symptom score increased significantly(P<0.05).The vestibular function stability was rated from 0 degree to degree III,and the 20 subjects fell into 4(0 degree),16(I degree),0(II degree)and 0(III degree),and the vestibular illusion induced rate was 100%.CONCLUSION Using vestibular illusion simulation training system to stimulate subjects’vestibule can cause moderate vestibular response,induce vestibular illusion and have certain influence on cardiovascular function and distributed attention.This study provides reference for the formulation of training program of pilots’vestibular illusion simulation experience.
