Udhav Giri, Parul Raj Agrawal · International Journal of Scientific and Research Publications · 2020
Background: Motion sickness occurs due to mismatch sensory inputs between the visual and vestibular system.Vestibular and visual systems coordinate eye movement in order to stabilize retinal images during head rotation.When someone is in stationary position they can still get the impression of self motion under certain conditions known as vection.Aim: To find out the effect of virtual reality on motion sickness.Methodology: It was an experimental study of pre-post design.Total 40 subjects participated in the study.Subjects who experience motion sickness of score more than 3 in modified Borg rating scale for dizziness were included in the study.Virtual Reality headset was used to deal with the problem of motion sickness by habituating visual vestibular system to induce adaptation in the VOR.Frequency of intervention was 3 sessions lasting 6 minutes each for 2 weeks.Dizziness score recorded after every session.Result: Repeated measures ANOVA showed that that virtual reality habituation lead to slight reduction in dizziness scoring from day 1 to day 11 (p < 0.001). Conclusion:Result of the study concluded that Virtual Reality headset showed improvement in symptoms of motion sickness as measured through modified borg rating scale for dizziness.
