초록
허혈성 뇌졸중 환자에서 운동장애의 판단 및 예후 판정에 운동유발전위 (motor evoked potential : MEP)의 유용성을 알아보기 위해 정상대조군 24례와 허혈성 뇌졸중 환자 24례를 대상으로 대뇌피질 및 척추부위에 자기자극을 가하며 단모지외전근 및 무지외전근에서 MEP를 기록하였고 각각의 근육에서 대뇌피질을 자극하여 기록된 MEP의 잠복기에서 척추부위를 자극하여 기록된 MEP의 잠복기를 감한 차이로 CMCT를 산출하였다. 대조군은 24례 모두에게 MEP를 유발할 수 있었고 환자군에서는 24폐 중 무반응을 나타낸 경우가 각 근육에서 11례였다. 정상대조군과 MEP를 유발할 수 있었던 뇌졸중 환자에서 단모지외전근에서의 평균 CMCT는 각각
This study was undertaken to evaluate the clinical usefulness of magnetic motor evoked potential (MEP) in the diagnosis of stroke and predicting the motor improvement following stroke. The cortical, cervical and lumbar stimulations were performed in the case of 24 healthy controls and 24 ischemic stroke patients. The central motor conduction time (CMCT) was represented by the difference of latency to a target muscle between after transcranial stimulation and after cervical or lumbar stimulation. There was no case showing no response in controls. But in 11 out of 24 ischemic patients, we could not get cortical MEP. Mean CMCT of abductor pollicis brevis muscle was not significantly different in controls and stroke patients in whom MEPs were recorded. There were significant differences between mean CMCT of normal controls and that of stroke patients showing MEPs in AH Muscle. MEP Results from testing the stroke patients were correlated with site of lesion, degree of motor weakness and motor improvement after 1 to 2 months. These results suggest that magnetic MEP is easy and useful in electrophysiological test of central motor pathway and is useful indicator for representing the motor weakness and predicting the motor outcome in acute ischemic stroke patients.
