Abstract：Objective To investigate the effectiveness and safety of VR(virtual reality)simulated flight environment provocation tests in electroencephalogram(EEG)monitoring.Methods Based on the occupational environmental characteristics of flight personnel,this study designed VR-simulated flight glasses(Patent No.ZL202320554741.9)incorporating such scenarios as aircraft takeoff and landing,formation flight,maneuvering flight,and snow flight.From September 2020 to September 2023,60 flight personnel,60 healthy volunteers,and 100 patients with epilepsy underwent video-EEG monitoring and VR-simulated induction tests.The effectiveness of the VR simulated induction test was demonstrated by comparing the positive detection rates in different induction tests.Results Among the 100 patients with epilepsy,2(2％)were positive for intermittent photic stimulation(IPS),2(2％)for hyperventilation(HV),and 3(3％)for the VR simulated flight test.Both IPS and HV were negative in the 60 flight personnel and 60 healthy subjects.Additionally,1 of the 60 flight personnel experienced dizziness during the VR-simulated flight test,while 7 of the 60 healthy subjects felt dizzy during the test,with 1 discontinuing the test due to dizziness,nausea,and vomiting.Conclusion The VR simulated provocation tests have demonstrated good safety and the ability to induce epileptiform discharges.However,more studies with larger sample sizes are needed to validate the feasibility of using this approach during EEG monitoring of aircrew members.
