目的
本研究探讨眼球震颤频率与视动性旋转诱发运动病严重程度的关系。
方法和结果
87名受试者看到一个垂直条纹，旋转鼓16分钟。受试者的眼电图，vection评级，晕动病（SSMS）的主观症状进行了测量，在鼓旋转期间。受试者的胃电图（EGG）记录在整个基线和鼓旋转期间。计算鼓旋转与基线周期之间的EGG 4-9周/分钟（cpm）的光谱强度的比值。结果表明，眼震频率与向量评分（r = 0.40，p < 0.0001）、SSMS评分（r = 0.61，p < 0.0001）及转鼓前后EGG 4-9 cpm谱强度比值（r = 0.54，p < 0.0001）呈正相关。
结论
这些结果表明，更快的眼球运动的视动性眼震的频率更高的索引与运动病和胃快速心律失常的症状的发展。
PURPOSE
The present study investigated the relationship of the frequency of nystagmus to the severity of optokinetic rotation-induced motion sickness.
METHODS AND RESULTS
Eighty-seven subjects viewed a vertically striped, rotating drum for 16 min. Subjects' electrooculograms, ratings of vection, and subjective symptoms of motion sickness (SSMS) were measured during the drum rotation period. Subjects' electrogastrograms (EGGs) were recorded throughout the baseline and drum rotation periods. The ratios of the spectral intensity of EGG 4-9 cycles per minute (cpm) between drum rotation and baseline periods were calculated. The results indicated that the frequency of nystagmus was positively correlated with the ratings of vection (r = 0.40, p < 0.0001), scores of SSMS (r = 0.61, p < 0.0001), and ratios of EGG 4-9 cpm spectral intensity between drum rotation and baseline periods (r = 0.54, p < 0.0001).
CONCLUSION
These results demonstrated that more rapid eye movement indexed by higher frequency of optokinetic nystagmus are related to the development of symptoms of motion sickness and gastric tachyarrhythmia.
