We sought to obtain normative values for radial nerve F-wave variables, recording with surface electrodes from the anconeus muscle.
We tested 30 healthy participants (17 women, 13 men) and measured the following variables: number of F waves/40 traces (F%); minimum, maximum, and mean F-wave latency (FMIN, FMAX, FMED, respectively); F-wave chronodispersion (FCHR); interside differences of F% and FMIN (DF% and DFMIN, respectively).
The mean F% was 41.3%; the normative values of FMIN, FMED, FMAX, and FCHR were < 21.2, <22.1, <23.3, and < 4.0 ms, respectively; and normative values of DF% and DFMIN were < 16.6% and < 1.1 ms, respectively. Height was the sole independent predictor in a regression model of FMIN, FMED, and FMAX; this explained 37%-44% of the variability.
We identified a feasible and useful technique to record radial nerve F waves from the anconeus muscle and obtained normative values of F-wave variables. Muscle Nerve 59:244-246, 2019.
我们试图从肱三头肌获得通过表面电极记录的桡神经 F 波变量的正常值。
我们测试了 30 名健康参与者（17 名女性，13 名男性），并测量了以下变量：40 个迹线的 F 波数/F%；最小、最大和平均 F 波潜伏期（FMIN、FMAX、FMED）；F 波时程离散度（FCHR）；F%和 FMIN 的侧间差异（DF%和 DFMIN）。
F%的平均值为 41.3%；FMIN、FMED、FMAX 和 FCHR 的正常值分别为<21.2、<22.1、<23.3 和<4.0 ms；DF%和 DFMIN 的正常值分别为<16.6%和<1.1 ms。身高是 FMIN、FMED 和 FMAX 回归模型的唯一独立预测因子，解释了 37%-44%的变异性。
我们确定了一种可行且有用的技术，可以从肱三头肌记录桡神经 F 波，并获得 F 波变量的正常值。《肌肉神经》59：244-246，2019 年。
