The aim of this study was to evaluate the nausea and autonomic dysfunction induced by virtual reality (VR) using electrogastrogram (EGG) and heart rate variability (HRV) analysis that were obtained from sixteen male normal volunteers. The VR video had a cylindrical shape with alternating black and white vertical stripes inside, that have been rotated for 15 min around the clock. The total study protocol time was the 45 min divided into the 15 min before period, 15 min VR video stimulation period, and the 15 min after period, respectively. The control group had been only seen just still images of stripes. Also, it had been evaluated that the nausea, and recording of EGG and HRV were demonstrated though into the all experimental periods. VR video stimulation had induced the nausea at motion sickness in the subjects of 90%. It had been obtained that the decrease of normogastria (p<0.05), which was accompanied with an increase of dysrhythmia (p<0.05) in EGG. However, there were no changes in heart rate, HF and LF/HF. Therefore, we had established inducing the nausea at motion sickness and dysrhythmia of EGG by the VR video stimulation with easy.
