A simple method has been devised to measure the refractory period of motor fibers in man. With paired shocks of just maximal intensity, the second response of the pair was first elicited at an interstimulus interval of 1.00+/-0.20 msec (mean +/- SD in 24 ulnar nerves). With longer intervals there was progressive return of excitability until it recovered completely at 2.88+/-0.72 msec. When paired shocks of 50% supramaximal intensity were used, return of the second response was faster, beginning at 0.77+/-0.18 msec and achieving full recovery at 2.03+/-0.57 msec. The inpulse was conducted at a slower speed than normal, if transmitted at all, during the relative refractory period.
已设计出一种简单方法来测量人体运动纤维的不应期。使用刚好最大强度的成对电刺激，该对刺激中的第二个反应最初在刺激间隔为1.00±0.20毫秒时引出（24条尺神经中的平均值±标准差）。间隔时间更长时，兴奋性逐渐恢复，直到在2.88±0.72毫秒时完全恢复。当使用50%超最大强度的成对电刺激时，第二个反应的恢复更快，从0.77±0.18毫秒开始，在2.03±0.57毫秒时完全恢复。在相对不应期，如果冲动能够传导，其传导速度比正常情况慢。
