OBJECTIVE:Changes in EEG patterns during stroke are almost immediate; however, a full EEG test takes time and requires highly qualified staff. In this study, we examined whether a short recording using a portable EEG device can differentiate between a stroke and control group. METHODS:EEG samples were collected from patients with an acute ischemic stroke event. The control group comprised healthy volunteers. EEG recordings were recorded using a portable brain wave sensor device. The Revised Brain Symmetry Index (rsBSI) was used to quantify the symmetry of spectral power between the two hemispheres. RESULTS:The investigation group included 33 patients (ages 46-96, mean age 72 years, 66% male) who were diagnosed with ischemic stroke. The control group included 25 healthy individuals. Scores for the rsBSI of non-stroke patients (M=0.1686, SD=0.10) differed significantly from those of ischemic stroke patients (P<0.05, M=0.363, SD=0.25). CONCLUSIONS:A statistically significant difference was observed between a group of stroke patients and a matched group of healthy controls with a short recording using a portable EEG device.

目的:卒中期间脑电图模式的变化几乎是立即发生的。但是,完整的EEG测试需要时间,并且需要高素质的员工。在这项研究中,我们检查了使用便携式EEG设备进行的短记录是否可以区分中风组和对照组。
方法:从急性缺血性中风事件的患者中收集脑电图样本。对照组包括健康志愿者。使用便携式脑波传感器设备记录脑电图记录。经修订的大脑对称性指数(rsBSI)用于量化两个半球之间频谱功率的对称性。
结果:研究组包括33名被诊断为缺血性中风的患者(46-96岁,平均年龄72岁,男性66%)。对照组包括25名健康个体。非卒中患者的rsBSI评分(M = 0.1686,SD = 0.10)与缺血性卒中患者的rsBSI评分显着不同(P <0.05,M = 0.363,SD = 0.25)。
结论:使用便携式脑电图设备进行短时记录的一组中风患者与健康对照组的配对组之间存在统计学上的显着差异。
