Nerve conduction study is an important tool to evaluate peripheral nerve abnormality. The primary purpose of this study was to provide normative electrophysiological data for commonly tested upper limb nerves in normal healthy adults. Nerve conduction studies were performed prospectively in upper limbs of 175 carefully screened healthy volunteers between the ages of 18 and 66 years using standardized techniques. There was no statistically significant difference found in conduction velocity and amplitude of motor median and ulnar nerves as well as sensory conduction velocity of median nerve. However, distal and F-minimum latencies of motor nerves, sensory amplitudes and conduction velocity of ulnar nerve was found to be significantly influenced by gender (P < 0.05). This study established normative conduction parameters of the commonly tested nerves of upper limb for our clinical neurophysiology laboratory in Central India. This can be of use to evaluate the patients with peripheral nerve abnormalities who reside in this particular geographic set-up. Gender was shown to have an influence on sensory amplitude, distal motor and F-minimum latencies of median and ulnar nerves.
神经传导研究是评估周围神经异常的重要工具。本研究的主要目的是为正常健康成年人中常见检测的上肢神经提供规范性电生理数据。使用标准化技术对175名年龄在18至66岁之间经过仔细筛选的健康志愿者的上肢进行前瞻性神经传导研究。运动正中神经和尺神经的传导速度和波幅以及正中神经的感觉传导速度未发现有统计学显著差异。然而，发现运动神经的远端和F波最小潜伏期、尺神经的感觉波幅和传导速度受性别显著影响（P < 0.05）。本研究为印度中部我们的临床神经生理学实验室建立了上肢常见检测神经的规范性传导参数。这可用于评估居住在这一特定地理区域的周围神经异常患者。研究表明，性别对正中神经和尺神经的感觉波幅、远端运动和F波最小潜伏期有影响。
