背景和目的卒中恢复机制仍不完全清楚，尤其是对于皮质性卒中受试者，可获得的数据有限。我们使用功能磁共振成像来比较正常对照组和偏瘫恢复者的脑活动。方法对10例恢复良好的中风患者，5例深部中风患者和5例皮质梗塞患者进行功能磁共振成像。通过食指轻拍实现脑激活。使用t检验和P的阈值获得统计参数激活图
Background and PurposeStroke recovery mechanisms remain incompletely understood, particularly for subjects with cortical stroke, in whom limited data are available. We used functional magnetic resonance imaging to compare brain activations in normal controls and subjects who recovered from hemiparetic stroke.MethodsFunctional magnetic resonance imaging was performed in ten stroke subjects with good recovery, five with deep, and five with cortical infarcts. Brain activation was achieved by index finger-tappine. Statistical parametric activation maps were obtained using a t lest and a threshold of P
