Motion Sickness Prevention by Stroboscopic Environment during Simulated Military Transport
Abstract
Previous studies have shown stroboscopic illumination to reduce the severity of motion sickness symptoms when retinal slip is a significant factor. The present study assessed the use of a 4 and an 8 Hz stroboscopic environment as a countermeasure for visually-induced motion sickness. The motion profiles of an Army UH-60 Black Hawk helicopter and a Marine AAVC7A1 Amphibious Assault Vehicle were produced using the U.S. Army Aeromedical Research Laboratory's Multi Axis Ride Simulator. Participants who experienced the UH-60 motion profile subjectively reported the 8 Hz condition as significantly more effective in controlling motion sickness symptoms than the 4 Hz condition. In addition, the same participants reported a greater mean number of motion sickness symptoms (regardless of severity) after the no strobe condition than the 8 Hz condition; however this difference was not significant. Although there was no conclusive evidence of stroboscopic illumination as a motion sickness countermeasure in the objective performance measures, there was evidence of its effectiveness in subjective reports.
