The impact of technique variation on the wave-form characteristics of the evoked sensory potential was determined from the median and ulnar nerves of healthy subjects. The conduction characteristics of latency, amplitude, and duration were determined for orthodromic and antidromic techniques of stimulation as measured under each of three recording modes: 1) single evoked response, 2) superimposition, and 3) electronic averaging. Variation in the technique of stimulation significantly affected each of the three wave-form characteristics. Peak latency and duration of the evoked sensory potential were longer in antidromic stimulation. The amplitude of the sensory potential varied significantly with both recording and stimulating techniques. The amplitude of the sensory response was larger in antidromic stimulation than in orthodromic stimulation and also was found to be smaller with electronic averaging than with the other recording modes in both antidromic and orthodromic conduction techniques. This degree of variation requires that standardized techniques of methodology be established with the development of normal values for the particular laboratory.
从健康受试者的正中神经和尺神经测定技术变化对诱发感觉电位波形特征的影响。在三种记录模式下测量时，针对顺向和逆向刺激技术确定潜伏期、波幅和时程的传导特征：1）单次诱发反应，2）叠加，3）电子平均。刺激技术的变化显著影响了三种波形特征中的每一种。诱发感觉电位的峰潜伏期和时程在逆向刺激时更长。感觉电位的波幅随记录和刺激技术的不同而有显著变化。感觉反应的波幅在逆向刺激时比顺向刺激时更大，并且发现在逆向和顺向传导技术中，电子平均时的波幅比其他记录模式时更小。这种变化程度要求随着特定实验室正常值的建立，制定标准化的方法技术。
