Temperature control and standardized technique, along with consideration of age, height, finger circumference, and instrumentation is imperative for appropriate interpretation of electrodiagnostic studies. Normative data must be based on these factors in adequate numbers of healthy subjects. This study provides comprehensive normative electrodiagnostic data for the median and ulnar nerves. Forty-four subjects participated in this study. The median motor studies showed a motor distal latency (DL) of 3.2 (0.4)msec, and distal amplitude (DAMP) of 12.1 (3.8)mV and sensory studies showed a DL of 2.5 (0.2)msec, and DAMP of 31.4 (8.7) microV for the men and 52.4 (14.3)microV for the women. The ulnar motor studies showed a motor DL of 2.6 (0.3)msec, and DAMP of 12.6 (2.3)mV and sensory studies showed a DL of 2.4 (0.2)msec, and DAMP of 27.0 (7.8)microV for the men and 52.9 (13.9)microV for the women. Sidedness and handedness did not affect the nerve conduction parameters of this study. Aging changes for these nerves were minimal but more apparent for the median nerve. The most noticeable change with aging was the decrease in amplitude of the sensory nerve action potential.
温度控制和标准化技术，以及对年龄、身高、手指周长和仪器设备的考虑，对于正确解读电诊断研究至关重要。规范数据必须基于足够数量健康受试者的这些因素。本研究提供了正中神经和尺神经全面的规范电诊断数据。44名受试者参与了本研究。正中神经运动研究显示，男性运动远端潜伏期（DL）为3.2（0.4）毫秒，远端波幅（DAMP）为12.1（3.8）毫伏；感觉研究显示，男性DL为2.5（0.2）毫秒，DAMP为31.4（8.7）微伏，女性为52.4（14.3）微伏。尺神经运动研究显示，男性运动DL为2.6（0.3）毫秒，DAMP为12.6（2.3）毫伏；感觉研究显示，男性DL为2.4（0.2）毫秒，DAMP为27.0（7.8）微伏，女性为52.9（13.9）微伏。本研究中，神经传导参数不受左右侧别和利手的影响。这些神经的老化变化很小，但正中神经更为明显。随着年龄增长，最明显的变化是感觉神经动作电位波幅降低。
