摘要
应用经皮电刺激大脑皮层及脊髓诱发肌肉动作电位检查方法,研究64名健康成人和22例中枢神经系统疾病患者的锥体束传导机能。结果表明,以中枢内运动神经传导时间作为中枢运动神经系统诱发电位的客观指标,不仅具有较高的特异性,而且可以提示早期或亚临床性锥体束损害。
Muscle responses evoked by of transcranial high voltage electrcal stimu lation in the normal controls and 22 patients with CNS disorders were studied to investigate the funotion of pyramidal tract. A prolcogation off the central moter conduction time between the cerebral motor coctex and the cervical enlargement of the spinal cord was found in ratients with clinical pyramidal signs. This method provide a simple, specific and practical technique for the evaluation of clinical and subclinical pyramidal tract disfuntion.
