Reference electrode position affects nerve conduction study results. This study was undertaken to determine the optimal reference electrode position for ulnar motor recording from the first dorsal interosseous (FDI) muscle and to develop normative data.
Fifty-one subjects were tested using reference electrode positions on the thumb, index, and little fingers. Latencies were compared with a needle recording from the FDI. Analysis was performed to determine the surface placement that most closely matched the needle recording latency. A normative database was then derived on 100 healthy subjects.
Placing the reference electrode on the thumb yielded results closest to the "gold standard" needle recording latency. The 97th percentile (upper limit of normal) for latency was 4.0 ms. The 3rd percentile values (lower limit of normal) for amplitude were 9.0 mV for men and 9.3 mV for women.
The reference position on the thumb yields latencies that most closely approximate needle recording. Normative data are presented.
参考电极位置会影响神经传导研究结果。本研究旨在确定从第一背侧骨间肌（FDI）进行尺神经运动记录时的最佳参考电极位置，并建立正常数据。
对51名受试者使用拇指、示指和小指上的参考电极位置进行测试。将潜伏期与FDI的针极记录进行比较。进行分析以确定最接近针极记录潜伏期的表面电极放置位置。然后从100名健康受试者中得出一个正常数据库。
将参考电极置于拇指上所得到的结果最接近“金标准”针极记录潜伏期。潜伏期的第97百分位数（正常上限）为4.0毫秒。男性波幅的第3百分位数（正常下限）为9.0毫伏，女性为9.3毫伏。
拇指上的参考位置所产生的潜伏期最接近针极记录。给出了正常数据。
