A modified sensory "inching" method for the electrodiagnosis of carpal tunnel syndrome (CTS) is described. The median nerve as stimulated at the cubital portion, with 8 channel recording electrodes placed along the nerve across the carpal tunnel. In most of the CTS cases, there was a conductive abnormality from 3 to 4.5 cm distal to the proximal ending of the flexor retinaculum. Subjects' values, obtained by subtracting the theoretical latency from the measured latency, which were more than 0.6 ms, could not be improved by conservative therapy. As we could determine from subtle change at the short span of nerve conduction, below the electrodes from the proximal to the affected site of the carpal tunnel, this method provides high sensitivity and specificity for the diagnosis of CTS.
本文描述了一种改良的感觉“渐进”法用于腕管综合征（CTS）的电诊断。在肘段刺激正中神经，8通道记录电极沿神经横跨腕管放置。在大多数CTS病例中，在屈肌支持带近端末端远侧3至4.5厘米处存在传导异常。通过从测量潜伏期减去理论潜伏期获得的受试者值若超过0.6毫秒，则保守治疗无法改善。由于我们可以从神经传导短节段的细微变化中确定，即从腕管近端到受影响部位电极下方的变化，该方法对CTS诊断具有高敏感性和特异性。
