Spinal and cortical somatosensory evoked potentials (SEP) to median nerve stimulation were recorded in 72 healthy subjects (38 men, 34 women, aged 44.5 +/- 9.4 years, height 172 +/- 7.9 cm), with the intention to establish the influence of age, height, sex and dominant hemisphere on the latencies of components N9, N13, P15, N20, P22, P40, and the N9-N13, P15-N20, P15-P22 and N13-N20 condition times (interpeak latencies). Significant correlation was found between the age, the height, and all registered SEP components. No significant correlation was found between conduction times and the height, with the exception of N9 N13 conduction time. Significant correlation was found between the age, the sex, and N13-N20 conduction time. For the P15-N20 and P15-P22 conduction times, correlation with the age and sex was poor, and it did not exist for the N9-N13 conduction time. Between the dominant and non-dominant hemisphere there were no significant differences in latencies of SEP components and conduction times. Therefore, the analysis of SEP components and conduction times, must concern the age, the height and the sex. Dominant hemisphere can be neglected because it has no influence on SEP components.
对72名健康受试者（38名男性，34名女性，年龄44.5±9.4岁，身高172±7.9厘米）进行了正中神经刺激下的脊髓和皮质体感诱发电位（SEP）记录，目的是确定年龄、身高、性别和优势半球对N9、N13、P15、N20、P22、P40各成分潜伏期以及N9 - N13、P15 - N20、P15 - P22和N13 - N20条件时间（峰间潜伏期）的影响。发现年龄、身高与所有记录的SEP成分之间存在显著相关性。除N9 - N13传导时间外，传导时间与身高之间未发现显著相关性。发现年龄、性别与N13 - N20传导时间之间存在显著相关性。对于P15 - N20和P15 - P22传导时间，与年龄和性别的相关性较差，而N9 - N13传导时间与年龄和性别不存在相关性。优势半球和非优势半球之间，SEP成分潜伏期和传导时间没有显著差异。因此，对SEP成分和传导时间的分析必须考虑年龄、身高和性别。优势半球可以忽略，因为它对SEP成分没有影响。
