Abstract
Transcranial electrical motor evoked potentials (MEP) were examined in 33 patients within three days after stroke. Normal values for MEP and motor central conduction time (CCT) were obtained in 46 healthy controls whose MEPs were evaluated during slight voluntary muscle contraction and at rest. Two months later 23 patients were re-examined clinically and electrophysiologically. Motor function change was correlated with MEP results. Two months after stroke the patients with normal or prolonged CCT had an improved motor function compared with those with absent CCT. MEP may be a valuable prognostic indicator in the acute stage of paralytic stroke for recovery of motor function.
摘要
对33例脑卒中患者在发病后三天内进行了经颅电刺激运动诱发电位（MEP）检查。对46名健康对照者在轻微自主肌肉收缩和静息状态下进行MEP评估，得出了MEP和运动中枢传导时间（CCT）的正常值。两个月后，对23例患者进行了临床和电生理复查。运动功能变化与MEP结果相关。脑卒中后两个月，CCT正常或延长的患者与CCT消失的患者相比，运动功能有所改善。MEP可能是瘫痪性脑卒中急性期运动功能恢复的一个有价值的预后指标。
