The influence of age and height on somatosensory evoked potentials (SEP) following median and tibial nerve stimulation was studied. Age correlated with increase of latencies and decrease of amplitudes; exceptionally the amplitude of cortical N20 component increased with age. The central conduction time P31-P40 (tibial nerve stimulation) was longer in elderly subjects, whereas the time N13-N20 (median nerve stimulation) was independent of age. Height showed a positive correlation with latencies and peripheral conduction times; central conduction times (N13-N20 and P31-P40) were independent on height. The correlations of SEP parameters with age and height were expressed quantitatively by regression equations. The presented equations should be treated as a valuable complement to normative data in interpretation of SEP testing results.
研究了年龄和身高对正中神经及胫神经刺激后体感诱发电位（SEP）的影响。年龄与潜伏期延长及波幅降低相关；例外的是，皮层N20成分的波幅随年龄增加。老年受试者中，胫神经刺激的中枢传导时间P31 - P40较长，而正中神经刺激的时间N13 - N20与年龄无关。身高与潜伏期及外周传导时间呈正相关；中枢传导时间（N13 - N20和P31 - P40）与身高无关。SEP参数与年龄和身高的相关性通过回归方程进行定量表达。在解释SEP检测结果时，所给出的方程应被视为对标准数据的有价值补充。
