摘　　要：目的:观察比较躯体感觉诱发电位(somatosensoryevokedpotentials,SEP)和运动诱发电位(motorevokedpotentials,MEP)两种检测方法对脊髓功能变化的敏感度,探讨SEP和MEP检测在脊髓损伤功能评价及疗效中的应用。方法:采用Keypoint型肌电图诱发电位仪和MaglitecompactⅤ型磁刺激仪对36例脊髓损伤(Spinalcordinjury,SCI)患者入院时进行SEP和MEP检查,出院时复查SEP和MEP,对照分析20例门诊体检的健康志愿者SEP和MEP,观察治疗前后SEP和MEP潜伏期和波幅的变化。结果:36例SCI患者治疗前SEP和MEP潜伏期延迟,波幅降低,治疗后均有明显变化,SEP和MEP潜伏期缩短,波幅增高,前后比较,差异有极显著性意义(P<0.01)。结论:SEP和MEP是一种定量、客观的脊髓电生理检测技术,准确性好,灵敏度高,可作为SCI功能及疗效评定的依据。AIM:To observe and compare the sensitivity of the two monitorings,somatosensor y evoked potentials(SEP) and motor evoked potentials(MEP) to the function change s of spinal cord injury(SCI),and to explore the application of SEP and MEP monit oring in the function assessment and therapeutic effect of SCI.METHODS:Thirty-six SCI patients received SEP and MEP examination with Keypoin t electromyograph of evoked potential and Maglitecompact V stimulator when they were hospitalized and discharged.The SEP and MEP of 20 health voluteers were rec orded and analyzed as the control.The variance of latency and amplitude of wave of the SEP and MEP recorded was analyzed in pretreatment and post-treatment. RESULSTS:The latencies of SEP and MEP of 36 SCI patients were obviously prolon ged and the amplitude of wave was decreased before treatment while shortened and increased respectively after treatment,so there was significant difference in t he latency and amplitude of wave between pretreatment and post-treatment.CONCLUSION:The SEP and MEP are a kind of quantitative and objective electrophy siological assessment for spinal cord injury.It can be used as the evidence for the evaluation of function and effect after SCI for its exact veracity and high sensitivity.
