INTRODUCTION
We describe a new nerve conduction study technique with reference values for the 3 branches of the supraclavicular nerve (SCN) in young healthy subjects and application of it in 2 patients.
METHODS
The recording electrode was placed on the posterior border of the sternocleidomastoid muscle, 6-7 cm from the sternoclavicular joint. SCN branches were stimulated below the clavicle, 2.5, 7, and 10.5 cm lateral to the sternoclavicular joint.
RESULTS
Twenty healthy volunteers (10 men), 19-38 years, mean 25.9 years (SD 6.3), and 2 patients with SCN lesions were studied. The mean conduction velocities of the SCN branches were 70-78 m/s (SD 8-10 m/s), and amplitudes 3-4 µV (SD 0.9-2.0 µV). There were no side-to-side or gender differences.
DISCUSSION
The 3 SCN branches could be studied in all subjects. We provide reference values for young subjects. This new method was useful in verifying SCN lesions in 2 patients. Muscle Nerve 58: 300-303, 2018.
简介
我们描述了一种新的锁骨上神经（SCN）传导研究技术，包括年轻健康受试者 SCN 3 个分支的参考值，并在 2 例患者中应用。
方法
记录电极置于胸锁乳突肌后缘，距胸锁关节 6-7cm。SCN 分支在锁骨下、锁骨下 2.5、7 和 10.5cm 处刺激。
结果
20 名健康志愿者（男 10 名，女 10 名），年龄 19-38 岁，平均 25.9 岁（标准差 6.3），2 例 SCN 病变患者。SCN 分支的平均传导速度为 70-78m/s（标准差 8-10m/s），波幅为 3-4µV（标准差 0.9-2.0µV）。无侧别或性别差异。
讨论
所有受试者均能研究 SCN 的 3 个分支。我们为年轻受试者提供了参考值。这种新方法在验证 2 例 SCN 病变患者中是有用的。《肌肉神经》58：300-303，2018 年。
