A study was made of 11 patients with cervical rib, and one patient with Klippel-Fiel syndrome and enlarged transverse processes to determine whether evoked potentials recorded from both Erb's points and the cervical spine in response to median and ulnar nerve stimulation provided information additional to that obtained by EMG and peripheral conduction studies. It was found that in seven patients who had pain and paraesthesias but no objective neurological signs both the peripheral and central conduction studies were within normal limits. By contrast, of five patients who had objective signs, conventional EMG and conduction studies were abnormal in three patients, but abnormalities of the evoked potentials obtained from ulnar nerve stimulation were obtained in all five patients. It is suggested that this application of evoked potential estimation is a useful addition to the more conventional peripheral investigations.
对11例颈肋患者以及1例患有克利佩尔-费尔综合征且横突增大的患者进行了一项研究，以确定在正中神经和尺神经刺激下从埃布点和颈椎记录的诱发电位是否能提供除肌电图和外周神经传导研究之外的额外信息。结果发现，7例有疼痛和感觉异常但无客观神经体征的患者，其外周和中枢神经传导研究均在正常范围内。相比之下，5例有客观体征的患者中，3例患者的传统肌电图和神经传导研究异常，但5例患者经尺神经刺激获得的诱发电位均有异常。有人认为，诱发电位评估的这种应用是对更传统的外周检查的有益补充。
