按美国脑电图学会推荐操作标准，对１８０名０－１４岁健康小儿同时进行双侧正中神经、胫神经短潜伏期体感诱发电位（ＳＳＥＰ＿ｓ）测试。获得各年龄组主要波群峰潜伏期（ＰＬ）、峰间潜伏期（ＩＰＬ）、传导速度及侧间差正常值。传导速度最不受身长、肢长影响，可列入ＳＳＥＰ＿ｓ判断指标。ＳＳＥＰ＿ｓ在小几时期的发育以周围段传导速度最快、脊髓次之、颅内最慢。周围传导功能大都在生前已发育，而中枢段王要在生后。 According to the recommended standard of American EEG, simultaneously 180 SS children aged 0-14 years old were tested for SSEP_s at the same time. The main wave peak latency (PL), peak latency (IPL), conduction velocity and normal lateral difference between each age group were obtained. Conductive speed least affected by length, limb length, SSEP_s indicators can be included in the judge. SSEP_s in the development of a few period to peripheral segments of the fastest conduction, followed by the spinal cord, the slowest intracranial. Most of the conduction around the function has been developed during their lifetime, while the king of the central segment to be born.
