Responses evoked in the supraclavicular fossa (Erb's point) were recorded after stimulation of the median and ulnar nerves separately in both arms. The recordings were made in 20 healthy controls and 13 patients with unilateral thoracic outlet syndrome. In 12 of the 13 patients subsequent surgery clearly confirmed the diagnosis. Nine of the 13 patients showed abnormalities in the preoperative recordings at Erb's point. In all of these nine patients the relative amplitude difference on the affected side was outside the normal range. In two patients there was also abnormally low conduction velocity. The differences of amplitudes in the Erb's point responses between patients and controls were statistically significant. The suggestion is made that Erb's point responses evoked by stimulation of the median and ulnar nerves may be of diagnostic value in thoracic outlet syndrome and that the method is suitable as a supplement to conventional electroneurography in routine clinical practice.
分别刺激双臂的正中神经和尺神经后，记录锁骨上窝（Erb点）诱发的反应。对20名健康对照者和13名单侧胸廓出口综合征患者进行了记录。13名患者中有12名随后的手术明确证实了诊断。13名患者中有9名在术前Erb点记录中显示异常。在这9名患者中，患侧的相对振幅差异均超出正常范围。2名患者还存在传导速度异常降低的情况。患者与对照者在Erb点反应中的振幅差异具有统计学意义。有人提出，刺激正中神经和尺神经诱发的Erb点反应可能对胸廓出口综合征具有诊断价值，并且该方法适合作为常规临床实践中传统神经电图的补充。
