To evaluate the usefulness of the TenElectrodes, a new stimulator for inching test, in the diagnosis and localization of ulnar neuropathy at the elbow (UNE).
Sixty-two ulnar nerves in 40 control subjects and 24 ulnar nerves in 23 patients with typical symptoms and signs of UNE were studied. The inching test of ulnar motor nerve using TenElectrodes was done along 8 cm across the elbow in the extended position.
In the inching test of the control group, the mean segmental latency difference was 0.19+/-0.08 ms. Maximal latency difference over a 1 cm segment did not exceed 0.40 ms in any of the controls but exceeded 0.5 ms or more in all clinical UNE patients. In all UNE patients, the lesion sites were identified by the inching test using TenElectrodes: the retroepicondylar groove (54.2%), the humeroulnar arcade (29.2%), and dual compression (16.6%).
TenElectrodes is a useful stimulator for the inching test in the diagnosis of UNE. The precise localization of compression was possible in all patients with UNE and the most common site was the retroepicondylar groove.
评估一种用于微移试验的新型刺激器TenElectrodes在诊断和定位肘部尺神经病变（UNE）中的作用。
对40名对照受试者的62条尺神经以及23例有典型UNE症状和体征患者的24条尺神经进行研究。使用TenElectrodes对尺神经运动神经进行微移试验，在伸直位沿肘部8厘米进行。
在对照组的微移试验中，平均节段潜伏期差异为0.19±0.08毫秒。在任何对照组中，1厘米节段上的最大潜伏期差异均未超过0.40毫秒，但在所有临床UNE患者中均超过0.5毫秒或更多。在所有UNE患者中，使用TenElectrodes进行微移试验可确定病变部位：肱骨髁上沟（54.2%）、肱尺肌弓（29.2%）和双重压迫（16.6%）。
TenElectrodes是一种用于UNE诊断微移试验的有用刺激器。所有UNE患者均能实现压迫的精确定位，最常见的部位是肱骨髁上沟。
