The aim of this study was to investigate the EEG power spectra obtained during rest and mental processing in chronic stroke patients. Seventeen patients with stabilized unilateral cerebral ischemia, grouped according to the side of lesion, underwent quantitative EEG recordings during rest and attentive/cognitive tasks. EEG spectral values were compared with those of 11 healthy subjects. Patients displayed different EEG patterns from controls, under rest condition: patients with left hemispheric lesion were characterized by a preserved alpha and beta band "reactivity," with a lack of significant changes in slow band components. In patients with right hemisphere lesion, no significant changes of the slow and fast band activities were evident during each task. These findings indicate that different EEG patterns of activation characterize stroke patients with left and right hemispheric damage.
本研究的目的是调查慢性中风患者在静息和进行心理活动时获得的脑电图功率谱。17例单侧脑缺血病情稳定的患者，根据病变侧进行分组，在静息和注意力/认知任务期间进行定量脑电图记录。将脑电图频谱值与11名健康受试者的频谱值进行比较。在静息状态下，患者表现出与对照组不同的脑电图模式：左侧半球病变的患者表现为α和β波段“反应性”保留，慢波成分无明显变化。在右侧半球病变的患者中，每项任务期间慢波和快波活动均无明显变化。这些发现表明，不同的脑电图激活模式是左右半球受损中风患者的特征。
