Using a collision technique, the ulnar nerve was made refractory for a shorter distance normally covered in 0.5 ms or a longer distance covered in 1.5 ms. Studying the shorter refractory segment with paired shocks of maximal intensity, the test response first appeared (more than 5% of unconditioned response) at an interstimulus interval of 1.16 +/- 0.18 ms (mean +/- SD in 20 ulnar nerves). The conduction velocity of the test impulse then was 55.3% +/- 19.2% of normal. Recovery in amplitude of the test response was nearly complete (more than 95%) at 2.11 +/- 0.50 ms, when it was conducting at a speed of 81.2 +/- 17.4% of normal. The conduction velocity recovered to a level above 95% of normal at 2.65 +/- 0.65 ms. Whereas recovery in amplitude of the test response was unrelated to the length of the refractory segment, change in latency was greater with the longer refractory segment, although not in proportion to the distance.
采用碰撞技术，使尺神经在正常情况下0.5毫秒内所覆盖的较短距离或1.5毫秒内所覆盖的较长距离内产生不应期。用最大强度的成对刺激研究较短的不应期节段时，在20条尺神经中，测试反应首次出现（超过非条件反应的5%）时的刺激间隔为1.16±0.18毫秒（平均值±标准差）。此时测试冲动的传导速度为正常的55.3%±19.2%。当测试反应以正常速度的81.2%±17.4%传导时，在2.11±0.50毫秒时，测试反应的幅度恢复几乎完全（超过95%）。在2.65±0.65毫秒时，传导速度恢复到正常的95%以上。虽然测试反应幅度的恢复与不应期节段的长度无关，但较长的不应期节段潜伏期的变化更大，尽管与距离不成比例。
