Compression of the ulnar nerve across the elbow is a common clinical diagnosis frequently referred for electrodiagnostic evaluation. Motor conduction studies with recording over the abductor digiti minimi and stimulating proximal and distal to the ulnar notch have been the standard technique employed in these evaluations--mean, 60.0 m/s; SD 5.0 m/s. Two other techniques are described, with data from normal subjects, recording from proximal forearm muscles. One technique is a refinement of a previously described method recording from the flexor carpi ulnaris--mean, 63.0 m/s; SD, 4.7 m/s. The second is a newly developed technique recording from the flexor digitorum profundus--mean, 63.0 m/s; SD, 5.5m/s. All three methods were found to have a small range of comparable normal values, and appear to be easily and quickly performed with reliable and reproducible information. The techniques described enhance specific localization of ulnar nerve lesions, and may prove useful when more distal recording sites are unavailable.
尺神经在肘部受到卡压是一种常见的临床诊断，常需进行电诊断评估。在小指展肌处记录，并在尺神经切迹近端和远端进行刺激的运动传导研究，一直是这些评估中采用的标准技术——平均值为60.0米/秒；标准差为5.0米/秒。本文描述了另外两种技术，并给出了来自正常受试者的、从前臂近端肌肉记录的数据。一种技术是对先前描述的从尺侧腕屈肌记录方法的改进——平均值为63.0米/秒；标准差为4.7米/秒。第二种是新开发的从指深屈肌记录的技术——平均值为63.0米/秒；标准差为5.5米/秒。发现所有这三种方法的正常数值范围都较小且具有可比性，并且似乎能够轻松快速地完成，提供可靠且可重复的信息。所描述的技术增强了尺神经病变的具体定位，当无法使用更远端的记录部位时可能会证明有用。
