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.
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.
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).
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.
中风期间的脑电图模式变化几乎是即时的；然而，完整的脑电图测试需要时间，并且需要高度合格的人员。在这项研究中，我们研究了使用便携式脑电图设备进行短时间记录是否可以区分中风组和对照组。
从急性缺血性中风患者中采集脑电图样本。对照组由健康志愿者组成。使用便携式脑波传感器设备记录脑电图记录。使用修订后的大脑对称性指数（rsBSI）来量化两个半球之间频谱功率的对称性。
研究组包括 33 名（年龄 46-96 岁，平均年龄 72 岁，66%为男性）被诊断为缺血性中风的患者。对照组包括 25 名健康个体。非中风患者的 rsBSI 评分（M=0.1686，SD=0.10）与缺血性中风患者的评分（P<0.05，M=0.363，SD=0.25）有显著差异。
使用便携式脑电图设备进行短时间记录，在中风患者组和匹配的健康对照组之间观察到了统计学上的显著差异。
