摘要
采用经皮电刺激大脑皮层及脊髓,于肢体远端肌群记录的运动诱发电位(MEP)技术,对40例正常人进行了中枢运动神经—锥体束的功能测定。并对其机理和影响因素进行了探讨。结果表明,该方法能快速,准确地反映锥体束功能,是目前临床无创性诊断中枢运动神经系统疾病的理想方法。
This article has described a new techique for recording the motor evoked potentical (MEP) in the distal limbmu-scle,with percutaneous cerebral motor cortex and spinal eletrical stimulation.Using this technique,the central motor pathways-pyramidal tract function in 40 healthy volunteers was studied.The results showed that there was a statistical difference between the males and females except CMCT ( P<0.01 ).There was no statistical difference betw- een the right and left sides recordings ( P<0.05 ).No correlation was found between the results and age ( P<0.05 ) There were some correlations between low limb locormotor (or 1sp) and the body height (P<0.01 ).This technique would be very useful for the investigation of central motor pathways.
