Motion sickness has a high prevalence worldwide, being more frequent in children, but can also affect adults. It is more common in females. It results from a visual-vestibular conflict that occurs during locomotion in various types of transportation such as car, bus, plane and boat. The most dramatic form occurs in shipping. It causes nausea, vomiting, sweating, increased salivation, loss of appetite, malaise and hypotension. It is usually produced by vestibular stimulation, but can also be induced by visual stimuli. Both linear as angular accelerations generate motion sickness if applied for long periods in susceptible individuals. Recently there has been increased interest in this condition because of increased use of flight and automotive steering simulation technology. The aim of this study was to analyze vestibular disorders in adults with motion sickness. This is a prospective, case series. Patients were approached at the otolaryngology offices in Pedro Ernesto University Hospital and were evaluated for general and specific medical history and general and ear nose throat physical examination. Those with a history of ear disease were excluded. Later they were scheduled to perform audiometry and vestibular function tests with the graphic recording of the nystagmus by electronystagmography. The results of caloric tests found 3,33% of patients with abnormal PDN, 6,67% with abnormal PL, 3,33% with left hyperreflexia, , 3,33% with left hyporreflexia and 3,33% with left hyporeflexia. We also found some variation in the analysis of saccades, optcokinetic nystagmus and tracking eye movement. Our results were in accordance with the literature findings. Given the results, we observed that the study of motion sickness was very important for the evaluation of patients with this condition. Our study brings benefits to the medical sciences in general and in particular to otolaryngology, as it contributes to a greater understanding of motion sickness and stimulates further research in this area.
