[Observation of electronystagmogram in pilots under vestibular stimulation]

The relationship between electronystagmogram(ENG) and intensity of vestibular stimulation was observed in 62 pilots. 31 pilots received low intensity vestibular stimulation and the other 31 pilots received higher intensity vestibular stimulation. Electronystagmogram were recorded and analysed. The results showed that there was no relationship between the ENG parameters and stimulation intensity, but both slow phase and fast phase velocities and amplitudes were lower under Coriolis acceleration stimulus, while all of them were higher under angular acceleration and angular stimulations. It was also found that the fast phase amplitude of ENG was related to motion sickness symptoms of the subjects.
