ABSTRACT

Objective: To compare neurophysiological changes in participants/subjects before and after experience of the ride of vestibular illusion demonstrator (VID). STUDY DESIGN: Comparative observational study. Setting And Duration of Study: The study was carried out at an aeromedical institute of an airport of a third world country from June 2017 to August 2018. Patients and Methods: Healthy subjects (male and female) between ages 18 to 40 years were selected. As this study involved humans so all data was collected after prior approval of the president of the Ethical Committee of the airport authority. All the participants were briefed and a written informed consent was taken from the participants of the study. An in depth biometric proforma was distributed and filled by subjects. The participants were ensured of the confidentiality of the information. It was ensured that all the subjects were in good health and were suffering from no physical or mental ailment. Those subjects were excluded who had hypertension, diabetes, asthma, cardiac disease, ENT disease or psychiatric illness. Vitals signs were endorsed before the exposure ride to Vestibular Illusion Demonstrator (VID). Subjects were exposed to VID for 07 minutes and after that vital signs were checked. The Motion Sickness Assessment Questionnaire (MSAQ) was filled by the participants after the exposure. All collected data was analysed by SPSS (Statistical Package for Social Sciences) version 22. Results: Twenty (20) healthy individuals participated in this study. During the motion of VID 75% (15/20) individuals developed neurophysiologic changes leading to motion sickness like tachycardia(75%), vomiting(5%), nausea(40%), sweating(45%), disorientation(10%) , dizziness(35%), increased systolic BP(25%), decreased systolic BP(45%), increased diastolic BP(10%),decreased diastolic BP (45%). Conclusion: During the experience of VID, 75% individuals developed neurophysiologic changes due to the motion sickness.
