Behavioral psychophysical techniques were used to obtain strength-duration curves for the ulnar nerve at both threshold and suprathreshold levels. The functions well match those obtained with electrophysiologic procedures, but overcome many of the difficulities associated with traditional electrodiagnosis. An alternate means of presenting the data provides a parameter, the critical duration, that describes the ability of the stimulated nerve to integrate or summate energy over time. The very brief criticial duration for normal ulnar nerve and the similar functions at threshold and suprathreshold levels suggest possible mechanisms for the transduction and coding of percutaneous electrical stimuli.
行为心理物理学技术被用于获取尺神经在阈值和阈上水平的强度-持续时间曲线。这些函数与通过电生理程序获得的函数非常匹配,但克服了许多与传统电诊断相关的困难。呈现数据的另一种方法提供了一个参数,即临界持续时间,它描述了受刺激神经随时间整合或累加能量的能力。正常尺神经的临界持续时间非常短,以及在阈值和阈上水平的相似函数,提示了经皮电刺激的转导和编码的可能机制。
