title: [Comparison of evaluation methods on changes of facial microcirculation during induction of motion sickness].
abstract: In order to increase the accuracy of motion sickness grading criteria, infrared thermography and Laser Doppler microcirculation blood-flow detector were used in 60 healthy male individuals: before, immediately, and 20 min after paralleled-swing stimulation. Facial skin temperature and microvessel blood-flow were recorded. The results showed that facial skin temperature and blood flow in facial microvessels fell together with the appearance of pallor. However, the degree of pallor observed with naked eye was inconsistent with that found by thermography or facial blood flow. It suggests that the accuracy of grading might be improved with the use of thermography or measurement of facial microvessel blood flow.
