OBJECTIVE This work describes our efforts to obtain nerve conduction studies normal values in a pediatric cohort between birth and 3 years of age using the extrapolated norms or e-norms method. Interpretation of these studies poses major challenges when no reliable normal values can be found in the literature. METHODS The e-norms method was used to derive a reference range of upper and lower extremity sensory and motor nerve conductions normal values from a pediatric cohort referred to an EMG Laboratory for nerve conduction studies. RESULTS E-norms were calculated for Median, Ulnar, Superficial Peroneal, Sural, and Medial Plantar sensory studies, and for Median, Ulnar, Peroneal, and Tibial motor studies. CONCLUSIONS Pediatric electrodiagnostic testing is a very challenging undertaking. The ability to obtain and use normal values from the neurophysiologist's own referral pool adds great value to their diagnostic work-up. SIGNIFICANCE EMG and nerve conduction studies can yield invaluable information in the diagnostic work-up of young infants. Using the e-norms method improves on the analysis and interpretation of electrophysiological studies in this age group.

推导出非常年轻（<3 岁）的小儿神经传导正常值

目标这项工作描述了我们使用外推规范或电子规范方法在出生至 3 岁的儿科队列中获得神经传导研究正常值的努力。当在文献中找不到可靠的正常值时，对这些研究的解释提出了重大挑战。方法 使用 e-norms 方法从一个儿科队列中推导出上肢和下肢感觉和运动神经传导正常值的参考范围，该队列被转交给 EMG 实验室进行神经传导研究。结果 计算了正中、尺骨、腓浅、腓肠和足底内侧感觉研究，以及正中、尺骨、腓骨和胫骨运动研究的 E 范数。结论 小儿电诊断测试是一项非常具有挑战性的工作。从神经生理学家自己的转诊池中获取和使用正常值的能力为他们的诊断工作增加了巨大的价值。意义 EMG 和神经传导研究可以为小婴儿的诊断检查提供宝贵的信息。使用电子规范方法改进了对这个年龄段的电生理研究的分析和解释。
