This study was designed to evaluate the usefulness of a new multielectrode stimulator, TenElectrodes, in the diagnosis and localization of the compression site in the wrists of carpal tunnel syndrome (CTS) patients. Antidromic inching technique (IT) of the median nerve at the wrist was performed with the TenElectrodes, on 46 controls and 21 CTS patients. In controls, mean conduction delay per centimeter (CD/cm) was 0.21 milliseconds (ms), and maximal CD/cm was 0.27 ms in the segment 3 to 4 centimeters distal to the distal wrist crease. The abnormal cut-off value, calculated as the maximal CD/cm + 2SD, was 0.45 ms. In the CTS group, the maximal CD/cm was 0.56 ms in the segment 2 to 3 centimeters distal to the distal wrist crease, and the CD/cm values in all segments between the distal wrist crease and 4 cm distal to the distal wrist crease were greater than 0.45 ms. Antidromic IT using TenElectrodes may be an easy, fast and accurate method as the electrodes of the stimulator are aligned at 1-cm intervals and are adjustable to the wrist contour by springs.
本研究旨在评估一种新型多电极刺激器TenElectrodes在诊断和定位腕管综合征（CTS）患者手腕压迫部位方面的实用性。使用TenElectrodes对46名对照者和21名CTS患者进行了手腕正中神经的逆向微移技术（IT）。在对照者中，每厘米平均传导延迟（CD/cm）为0.21毫秒（ms），在腕部远侧腕横纹远端3至4厘米节段中的最大CD/cm为0.27 ms。异常临界值计算为最大CD/cm + 2标准差，为0.45 ms。在CTS组中，在腕部远侧腕横纹远端2至3厘米节段中的最大CD/cm为0.56 ms，并且在腕部远侧腕横纹与腕部远侧腕横纹远端4厘米之间的所有节段中的CD/cm值均大于0.45 ms。由于刺激器的电极以1厘米间隔排列并且可通过弹簧调节以适应手腕轮廓，使用TenElectrodes进行逆向IT可能是一种简单、快速且准确的方法。
