摘要
目的探讨脑电图/脑电地形图(EEG/BEAM)对脑梗死恢复期的诊断意义,其变化特征受哪些因素的干扰和影响。方法采用头部转动和手臂旋转法诱发脑梗死恢复期的EEG/BEAM的变化。结果经统计学分析,头部转动法引起的EEG/BEAM的改变,慢波、慢波绝对功率谱(三维图)变化异常率显著大于对照组,t=3.435,P<0.001,手臂旋转法引起的异常率亦大于对照组,P<0.05。结论头部转动和手臂旋转均可引起脑梗死恢复期颅内侧枝循环的变化,从而引起脑梗死的脑电活动的改变。
Aim To investigle the diagnositie effec t of EEG /BEAM in brain infarct convalenscence(BIC).Methods The change of EEG /BEAM in BIC was resulted by the head rotation and arm turning.Results The significant different ratio of the h ead rotation was more than control by statistics analysis,t=3.435,P<0.001,the different ratio of the arm turning was also more than control,P<0.05.Conclusion The change of the circulation of cranial cavity la teral branch and the electric moveme nt of brain cell in BIC are brought out the h ead rotation and arm turning.
