[Normal values of vestibular autorotation test in young people].
OBJECTIVE
To explore the normal values of vestibular autorotation test (VAT) in young people.


METHODS
VAT was performed in 31 young people aged 20-30 years. The measured value were analyzed and compared with the reference normal value.


RESULTS
The measured values of VAT in healthy young people are almost within the normal range of the general population. Compared with the reference normal values, the horizontal gains at 2.0, 2.3, 2.7, 5.5, and 5.9 Hz, the vertical gains at 2.0 and 5.9 Hz, and the vertical phases at 2.0, 2.3, 2.7, 3.1, 3.5, and 3.9 Hz were significantly different (P < 0. 05). No significant difference was shown in the horizontal phases and asymmetry.


CONCLUSIONS
The normal values of VAT in young people is within the reference normal range of the general population. The vestibular function of young people may be more sensitive in lower frequency range (2-3Hz).
