摘要：

目的探讨发作性头痛的脑波涨落图特征，为航空航天作业人员选拔提供参考方法。方法应用脑波涨落图技术分析了２０ 例临床诊断为发作性头痛的患者在７ ～１２ Ｈｚ 频段脑波优势频率涨落特征和该频段脑波的功率涨落功率谱特征。其中男性１３ 例，女性７ 例，年龄在１７ ～３７ 岁。结果在发作期，与头痛相对应的导联，脑波７ ～１２ Ｈｚ 频段各频率出现优势涨落概率高低依脑波频率由慢到快依次分布，即按７ 、８ 、９ 、１０ 、１１ 及１２ Ｈｚ 顺序排列。且由各频率优势涨落组成的有限概型的相对熵值为９２ ．２５ ％ ±３ ．４１ ％ ，该频段功率涨落在１ ．８６ ｍ Ｈｚ 和４ ．６５ ｍ Ｈｚ 出现优势功率谱峰。在间歇期，脑波７ ～１２ Ｈｚ 频段各频率优势涨落概率高低依脑波频率由慢到快依次分布现象消失，相对熵值下降为６９ ．０８ ％ ±４ ．１６ ％ ，功率涨落在１ ．８６ ｍ Ｈｚ 功率谱峰消失，在４ ．６５ ｍ Ｈｚ 功率谱峰降低，在０ ．９３ ｍ Ｈｚ 出现优势功率谱峰。结论此结果为发作性头痛提供了可参考的功能性评价指标，也对航空航天作业人员选拔有参考意义。

Abstract：

Objective To offer reference of the screening procedure for aircrew and astronaut selection. Method The competitive frequency fluctuation characteristics of the dominant frequency in the band of 7～12 Hz in EEG and power density spectra of α band power fluctuation were analyzed with a newer system of electroencephalofluctuographic technology in 20 patients (male 13, female 7, aged 17～37 years) with paroxysmal headache. Result During episodes of headache in the affected sites the cumulated dominant fluctuation probability of each frequency components was in the order of 7,8,9,10,11,12 Hz from high to low; The relative entropy value was 92.25%±3.41%; Two peaks having at least 25% higher value than those of its neighbors were observed at 1.86 mHz and 4.65 mHz in power density spectra of power fluctuation. During the intervals of episodes the above mentioned probability character disappeared; The relative entropy value was decreased to 69.08%±4.16%; A new peak was found at 0.93 mHz in spectra power fluctuation, with a reduction in peak value power at 4.65 mHz. Conclusion It not only offered a parameter for pathophysiological and functional evaluation of paroxysmal headache, but also provided reference of the screening procedure for aircrew and astronaut selection.
