Peripheral nervous system maturation in infancy and childhood varies with age, especially during the first 2 years of life. Electrophysiologic values therefore changes significantly between different age groups within these first 2 years and are different from adult values. Normal values of motor and sensory nerve conduction, distal motor latency, F-wave latency, and evoked response amplitude of peripheral nerves commonly tested are reported in 155 healthy children in seven age groups from 1 week to 14 years. Interval changes are clearly shown, and in comparison with adult values, the whole group has significantly slower nerve conduction velocities, with reduced muscle and nerve evoked response amplitudes. These differences are important to recognize when evaluating the peripheral nervous system of children.
婴儿期和儿童期外周神经系统的成熟随年龄变化，尤其是在生命的头两年。因此，在这头两年内，不同年龄组之间的电生理值会发生显著变化，且与成人值不同。本文报告了155名年龄从1周龄至14岁的七个年龄组健康儿童的运动和感觉神经传导、远端运动潜伏期、F波潜伏期以及外周神经通常检测的诱发电位幅度的正常值。明显显示出各年龄段之间的变化，并且与成人值相比，整个群体的神经传导速度明显较慢，肌肉和神经诱发电位幅度降低。在评估儿童外周神经系统时，认识到这些差异很重要。
