Nerve conduction studies are increasingly being performed on elderly individuals; however, no standardized data for the elderly population exists to provide an accurate interpretation of electrodiagnostic findings. The purpose of this study was to provide standardized data in the healthy elderly for the nerves of the upper limb that are routinely chosen for study by electromyographers. Nerve conduction studies were performed prospectively in one upper limb of 155 carefully screened healthy elderly individuals between the ages of 60 and 95 years. Upper limb temperature was controlled to limit the influence of temperature on the measured conduction parameters. Standard nerve conduction techniques using constant measured distances were applied to evaluate the median, ulnar and radial nerves. A normative electrodiagnostic database for elderly individuals was established in this study. The mean nerve conduction parameters of this healthy elderly population compared favorably with existing literature values for younger populations. However, age had a statistically significant but low strength effect on all ulnar nerve conduction velocities and distal latencies as well as the distal sensory amplitudes of all three nerves. Gender had a greater effect than age on these parameters as well as on median sensory distal latency. Other median motor and sensory conduction parameters along with radial sensory distal latency were not significantly related to age or gender based on two-way analysis of variance.
越来越多的老年人接受神经传导研究；然而，目前尚无针对老年人群的标准化数据来准确解读电诊断结果。本研究的目的是为健康老年人的上肢神经提供标准化数据，这些神经是肌电图检查人员常规选择进行研究的对象。对155名年龄在60至95岁之间经过仔细筛选的健康老年人的一侧上肢进行了前瞻性神经传导研究。控制上肢温度以限制温度对测量的传导参数的影响。采用使用恒定测量距离的标准神经传导技术来评估正中神经、尺神经和桡神经。本研究建立了老年人群的规范性电诊断数据库。该健康老年人群的平均神经传导参数与年轻人群的现有文献值相比具有优势。然而，年龄对所有尺神经传导速度、远端潜伏期以及所有三条神经的远端感觉波幅均有统计学意义但强度较低的影响。性别对这些参数以及正中神经感觉远端潜伏期的影响大于年龄。基于双向方差分析，其他正中神经运动和感觉传导参数以及桡神经感觉远端潜伏期与年龄或性别均无显著相关性。
