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.
为提高晕动病分级标准的准确性，对60名健康男性个体在平行摆动刺激前、刺激即刻及刺激后20分钟使用红外热成像仪和激光多普勒微循环血流检测仪，记录面部皮肤温度和微血管血流情况。结果显示，随着面色苍白的出现，面部皮肤温度和面部微血管血流均下降。然而，肉眼观察到的苍白程度与热成像或面部血流检测结果不一致。这表明，使用热成像或测量面部微血管血流可能会提高分级的准确性。
