摘要: 目的探讨Arnoid Chiari畸形(ACM)患者运动诱发电位(MEP)的变化规律。方法经MRI证实的30例Arnoid Chiari畸形患者接受电刺激运动诱发电位测试,对其中20例进行术后复查。结果Arnoid Chiari畸形患者MEP的中枢运动传导时间(CMCT)延长,异常率为96.7%(29/30),肌力减退愈重,MEP异常愈明显,Arnoid Chiari畸形Ⅱ型的MEP异常较Ⅰ型更显著,MEP的改变与肌力的改变明显相关。结论MEP改变比临床评定更为敏感,且能反映运动功能的损害程度;MEP可预测预后,能作为评定手术效果的客观指标。

Abstract: Objective To study the electrical stimulation motor evoked potentials in Arnoid Chiari malformation.Methods Electrical stimulation motor evoked potentials were recorded in 30 cases with Arnoid Chiari malformation proved by MRI.Results Abnormality rate of MEP was 96.7%,and the abnormal patterns mainly consisted of the delay of latency and the delay of central motor conduction time(CMCT). The change of MEP was connected with myodynamia and the type of Arnoid Chiari malformation .Conclusions The change of MEP is more sensitive than clinical change, and can indicate the damage of the motor function objectively and quantitatively, and MEP can be used as an objective criterion for surgical effect, and can predict the recovery of motor function.
