[Quantitative evaluation of the clinical manifestations of motion sickness]

An original scheme of quantitative evaluation of clinical manifestations of motion sickness has been developed. According to the scheme, eight major symptoms of motion sickness: vertigo, nausea, vomiting, sweating, paleness, headache, sleepiness, flaccidity are scored in relation to their manifestations. The scheme has been used in vestibular tests of 57 test subjects. The vestibular test used is tolerance to cross-coupled acceleration. On the basis of the scores quantitative criteria of human tolerance to vestibular exposures have been suggested. It is emphasized that the scheme can be widely used allowing statistical treatment, comparative individual and group analysis of the data obtained.
