Abstract: Objective To investigate the effect of electrical 3D gyro wheel(3D vestibular function trainer) on the selection of pilot vestibular function.Methods Twenty pilots were treated with both 3D vestibular function trainer for 5 min and rotating chairs for 90 s respectively.The physiological indexes such as blood pressure,heart rate,heart rate variability and respiration of the subjects were observed in each process.The vestibular function of each subject was rated according to his symptoms and complaints.The physiological parameters and heart rate variability were observed in this process,then vestibular function was ranked according to the symptoms and complaints of the pilots and the qualified rate was compared between the two methods.Results Compared 3D gyro wheel with the rotating chairs test,the heart rate and HFn of the pilots were significantly increased,LFn and LF/HF were significantly reduced (P ＜ 0.05).The qualified rates of vestibular function stability were both 95 ％.Conclusion The 3 D vestibular function trainer can be used for the selection of the stability of the vestibular function of pilots.
