Careful attention to technique is essential for the accurate evaluation of peripheral nerve function using conventional EMG and nerve conduction studies. Numerous technical, anatomic, and physiologic pitfalls must be avoided. The amplitudes of the M wave and SNAP contain useful diagnostic information and should be evaluated carefully in addition to conduction velocity and distal latency. Newer techniques using the F wave, H reflex, SEP, dermatomal SEP, and quantitative EMG may be helpful in evaluation of selected peripheral nerve problems. Comparative nerve conduction studies using "inching" technique permit evaluation of short nerve segments. Comparisons with parallel nerves improve diagnostic sensitivity.
在使用传统肌电图和神经传导研究准确评估周围神经功能时，仔细注意技术至关重要。必须避免许多技术、解剖和生理方面的陷阱。M波和感觉神经动作电位（SNAP）的波幅包含有用的诊断信息，除了传导速度和远端潜伏期外，还应仔细评估。使用F波、H反射、体感诱发电位（SEP）、皮节SEP和定量肌电图的新技术可能有助于评估某些周围神经问题。使用“分段法”技术进行对比神经传导研究可评估短神经节段。与并行神经进行比较可提高诊断敏感性。
