目的 研究飞行员视前庭相互作用与晕机病易感性的关系,探讨用前庭功能检查预测晕机病的可行性。方法 检测33名健康歼击机飞行员视前庭相互作用状况,并采用阶梯式累加科里奥利加速度刺激方法评定他们的晕机病易感性,将两项测试的指标进行相关分析。结果 科里奥利加速度耐力与前庭眼动反射、视眼动反射、视前庭眼动反射的增益及视眼动反射、视前庭眼动反射增益的两侧不对称性无显著相关,与前庭眼动反射增益的两侧不对称性呈显著负相关(r=-0.429,P<0.01)。结论 飞行员的科里奥利加速度耐力随前庭眼动反射增益的两侧不对称性增加而降低,飞行员前庭眼动反射增益的两侧不对称性值对于晕机病易感性的预测具有一定价值。
Objective To study the relationship between the visual acuity and the susceptibility to airsickness in pilots and to explore the feasibility of predicting airsickness with vestibular function. Methods The visual acuity of 33 healthy fighter pilots was examined. The staircase cumulative Coriolis acceleration stimulus was used to evaluate their susceptibility to motion sickness. The correlation between the two test indicators was analyzed. Results Coriolis acceleration endurance and vestibular eye reflex, oculomotor reflex, visual acuity of visual acuity gain and visual acuity reflex, visual acuity on both sides of the eye asymmetry asymmetry was not significantly correlated with the vestibular eye There was a significant negative correlation between asymmetry of dynamic reflection gain (r = -0.429, P <0.01). Conclusions The Coriolis acceleration endurance of pilots decreases with the increase of asymmetry of both sides of the vestibular ophthalmologic reflex gain. The asymmetry value of the two sides of the pilots’ vestibular ophthalmologic reflex gain is of certain value for predicting the susceptibility of the ailment disease.
