本文分析了132名健康人经单侧和双侧正中神经电刺激引出的体感诱发电位(SEPs)。应用双侧同时刺激和同时记录的方法,利于在相同条件下直接观察和对比左右半球的瞬间反应,有可能较以往单独用一侧刺激的方法更能证实SEPs异常或两半球的差别。本文统计的正常值与国内、外文献相近。 In this paper, 132 healthy subjects were analyzed by unilateral and bilateral median nerve stimulation induced somatosensory evoked potentials (SEPs). The application of bilateral simultaneous stimulation and simultaneous recording facilitates the direct observation and comparison of the instantaneous response of the left and right hemispheres under the same conditions and may be more capable of confirming the abnormality of SEPs or the difference between the two hemispheres than the previous method of stimulating with one side alone. The normal statistical value of this article is similar to that of domestic and foreign literature.
