摘要
对120例健康人进行体感诱发电位(SEP)检测。按不同性别、年龄分为成年组(30～59岁)及老年组(60～79岁)。结果表明,SEP各波潜伏期(PL)及波峰问期(1PL)的平均值左、右侧比较无统计学差异,但男、女组间,成年组与老年组间却有明显差异。Erb点电位(N_9)及颈髓电位(N_(13))的PL与臂长、身高呈正相关,有非常显著性意义。因此,临床判断病人的SEP值时,应考虑性别、年龄、臂长。身高等因素的影响,并注意选取正常值范围的界限,才能提高其诊断准确率。
The clinical study of somatosensory evoked potentials (SEP) is of extensive interest. Reports on normal range of SEP value have been available in the literature at home. Because of different laboratory conditions, difference between individuals and the effect of different factors, the normal range of SEP value has not yet been established. The purpose of this study was to find out the normal value of SEP in healthy subjects related to such factors as age, sex, height, and arm length. We have discussed how to determine the normal range of SEP value accurately in order to make it more useful in clinical diagnosis.
