The objective of the study is to observe the anti-motion sickness effect of volatile oil extract of Pinelia ternata in rats, compare the strength of anti-motion sickness action between the Pinelia ternata volatile oil extract and the dimenhydrinate, and analyze the constituents in volatile oil of Pinelia ternata. Rats with frequency is 0.05Hz, the peak speed of 240°/s rotated to stimulate, evok...

BACKGROUND Motion sickness may be caused by a sensory conflict between the visual and the vestibular systems. Scopolamine, known to be the most effective therapy to control the vegetative symptoms of motion sickness, acts on the vestibular nucleus and potentially the vestibulospinal pathway, which may affect balance and motor tasks requiring both attentional process and motor balance. The aim o...

Given a sufficiently provocative stimulus, almost everyone can be made motion sick, with approximately one-third experiencing significant symptoms on long bus trips, on ships, or in light aircraft. Current countermeasures are either behavioral or pharmacologic. Behavioral measures include habituation/desensitization treatment protocols as well as positioning the head in alignment with the direc...

The purpose of this study was to investigate whether nausea or gastric dysrhythmia, including tachygastria, which was determined by electrogastrography (EGG), were observed during optokinetic motion sickness in healthy Japanese volunteers. Twelve volunteers (9 men and 3 women) participated in the study. The subjects were asked to sit in a chair with their heads positioned in the center of a dru...

INTRODUCTION Nausea and motion sickness are important operational concerns for aviators and astronauts. Understanding the underlying mechanisms associated with motion sickness may lead to new treatments. The goal of this work was to determine if changes in cerebral blood flow precede the development of nausea in subjects susceptible to motion sickness. METHODS Cerebral flow velocity in the mi...

Motion Sickness, or kinetosis, is a complex clinical syndrome usually classified according to the environmental situation evoking the symptoms. Among the various forms of motion sickness, air sickness has a significant impact on aircrew readiness and is often a cause for the grounding of aircrew. Unfortunately, standards for clinical testing to accurately predict the sensitivity of each individ...

Previous user studies have suggested the occurrence of symptoms of motion or simulator sickness among active spectators of handheld projector interaction. Using the well-established Simulator Sickness Questionnaire proposed by Kennedy et al. in 1993, we asked twenty-six participants if they had any indication of such symptoms after they watched a demonstration of handheld projector interaction ...
