【摘要】 目的探讨三点电刺激法对2型糖尿病人神经近端损害的诊断价值。方法糖尿病人10例,健康人对照组21例。将CCS-Ⅰ大脑皮质电刺激仪与Keypoint肌电诱发电位仪联机,用表面电极记录左侧拇展肌的电刺激下的运动诱发电位,弓形表面刺激电极阳极在上、阴极在下,将阴极分别置于T12棘突、S1棘突和腘窝三点,用500V、0.1ms方波分别做一次性电刺激。结果糖尿病人与对照组在三点电刺激诱发运动诱发电位的潜时及波幅均有显著差异。T12-S1段、S1-腘窝、T12-腘窝三节段的传导时间顺时差,糖尿病人较对照组延长。糖尿病人较对照组,T12-S1段、T12-腘窝段运动传导速度减慢。结论三点电刺激法对2型糖尿病人神经近端损害的定位及节段性诊断是一种新的有价值的方法。更多还原

【Abstract】 Objective To investigate the diagnostic value of three-point stimulation method for localization the proximal peripheral nerve disorder in typeⅡdiabetes patients.Methods Ten patients with typeⅡdiabetes and 21 healthy person were selected for this study.A CCS-Ⅰtype transcutaneous electrical stimulator of cortex and Keypiont muscle evoked potential equipment were connected.Motor evoked potential of left abductor hallucis muscle was recorded by a arched superficial electrode,positive electrod was laid in superior,and negative electrod was laid in inferior,respectively.Each subject was given a squre wave（500V,0.1ms）stimulation after three negative electrodes were placed on T₁₂ spinous process,S₁ spinous process and popliteal fossa,respectively.Results Both latent period and amplitude of motor evoked potential in three stimulating points were significiant different between diabetes and control group.Although conductive time of diabetes group was longer than that of control group among S₁ to popliteal fossa,T₁₂ to popliteal fossa,motor conductive velocity of diabetes group were lower than control group among T₁₂ to S₁ portion,S₁ to popliteal fossa,T₁₂ to popliteal fossa.Conclusion Three-point stimulation method is a new and helpful approach to localize the proximal peripheral nerve disorder in type Ⅱ diabetes.更多还原
