摘要目的 检测飞行员头直立位静态主观视觉垂直线(subj ective visual vertical,SVV)和静态主观视觉水平线(subj ective visual horizontal,SVH)的偏斜角度,以及头向左或向右倾斜 45°时SVV和 SVH 的倾斜范围,为飞行学员医学选拔和飞行人员医学鉴定耳石器功能评价提供参考依据.方法 采用 XZ-2008 型主观视觉耳石器功能检测仪.①选取 100 名现役战斗机飞行员作为受试者,记录其头直立位 SVV偏斜角度的范围.②选取 24 名现役战斗机飞行员作为受试者,记录其头直立位 SVH 偏斜角度的范围,并分别记录其头向左或向右倾斜 45°的 SVV 和 SVH 倾斜角度范围.按x-±1.96 s 计算正常值范围. 结果 ①100 名飞行员头直立位 SVV 偏斜角度范围为-1.61°~1.73°;②24 名飞行员头直立位 SVH 偏斜角度范围为-2.34°~3.18°;头向左倾斜 45°时 SVV 偏斜角度范围为-7.12°~6.12°,头向右倾斜 45°时 SVV 偏斜角度范围为-6.76°~4.84°;头向左倾斜 45°时SVH 偏斜角度范围为-9.84°~6.74°,头向右倾斜 45°时 SVH 偏斜角度范围为-6.70°~6.20°. 结论 本研究建立了军事飞行员头直立位 SVV和 SVH 的检测方法和正常值范围,为飞行学员医学选拔和飞行人员医学鉴定时耳石器功能的评价提供了一项客观参考依据.头向左或向右倾斜 45°后SVV和 SVH 偏斜角度会发生变化,我们将进一步深入研究其临床意义,为军事飞行人员前庭功能医学鉴定提供依据.

abstractsObjective To provide the references on otolith function evaluation by investigating subj ective visual vertical (SVV)and subj ective visual horizontal (SVH),as well as the tilt range of SVV and SVH when pilot,s head tilted 45°to the left or right side for the selection and the medical evaluation of pilots . Methods XZ-2008 Otolith function test instrument was chosen for the tests.①One hundred active fighter pilots were chosen as the subj ects and the angle range of their head upright SVV was recorded.②Twenty-four active fighter pilots were chosen as the subjects.The angle range of their head upright SVV and the angle ranges of head 45°right or left tilt SVH and SVV were recorded.Normal value range was caculated according to Mean±1 .96 SD Results ①The angle range of head upright SVV of 100 pilots was -1 .61°-1 .73°.②The angle range of head upright SVH of 24 pilots was -2.34°-3.18°,the angle range of head 45°left tilt SVV was -7.12°-6.12°,and the range of -6.76°-4.84°for their head 45°right tilt.The angle range of 45°left tilt and 45°right tilt SVH was respectively -9 .84°-6.74°,and -6 .70°-6 .20°. Conclusions The study has established the test method and the normal angle range of SVV and SVH in military pilots,which is crucial for the assessment of the otolith function in medical selection and medical evaluation of military pilots.When head tilts to left or right by 45°the angles of SVV and SVH will change.We will further study its clinical signification and provide more evidence for the vestibular function medical evaluation of military flying personnel.
