经颅磁刺激运动诱发电位检测应用进展及法医学意义

摘要

经颅磁刺激运动诱发电位(transcranial magnetic stimulation-motor evoked potential,TMS-MEP)检查是评价中枢神经系统功能的一种神经电生理检查方法,其法医学应用价值已逐步得到一些法医学者的关注.本文综述了TMS-MEP的发展概况、原理、优势以及目前在评价中枢神经系统功能和临床治疗方面的研究和应用进展,探讨了TMS-MEP在法医学中的应用价值,尤其是对中枢神经系统损伤者客观肌力评定的意义.%Transcranial magnetic stimulation-motor evoked potential(TMS-MEP) test is one of the electrophysiological examination methods to evaluate the function of central nervous system. The value of the TMS-MEP has been recognized by some clinical forensic workers recently. This article reviews the principle and advantages of TMS-MEP and its application in functional evaluation of central nervous system and clinical treatment. The value of TMS-MEP in forensic medicine, especially in objective assessment of muscle strength after injury of central nervous system is also discussed.
