Abstract:
Objective To establish normal reference values of video head impulse test(vHIT)for civil avia-tion student pilots to provide a reference basis for the accurate assessment of the vestibular function of civil aviation student pilots.Methods Forty civil aviation student pilots in the theoretical training phase were randomly selected for vHIT.The average gain of the vestibulo-ocular reflex(VOR)and the asymmetry ratios of the semicircular ca-nals were compared.Results The VOR values for the right horizontal,anterior,and posterior semicircular canals were 1.05±0.07,0.92±0.13,0.81±0.09,respectively.For the left horizontal,anterior,and posterior semicir-cular canals,the values were 1.00±0.06,0.85±0.10,0.86±0.10,respectively.There was no compensatory sac-cade in any of the subjects.The asymmetry ratios of bilateral horizontal,left anterior-right posterior,and right an-terior-left posterior semicircular canals were 5.56％±3.64％,9.65％±4.74％,8.68％±7.07％,respectively.Conclusion This study establishes vHIT normal reference values for civil aviation student pilots,providing an ob-jective basis for their selection and vestibular function evaluation.
