Comparison of sensory nerve conductions in palmar cutaneous branch (PCB) and digit I nerves was applied in 50 patients suspected of having carpal tunnel syndrome (CTS) and 40 healthy persons. The abnormalities were defined as the differences in latencies and sensory nerve conduction velocities (SNCVs) of more than mean plus 2.5 SD of controls. Comparing these 2 sensory nerves, statistical differences were seen in 83.7% (36 of 43 patients) of their sensory latencies and 76.7% (33 of 43 patients) of their SNCVs. This excluded 7 patients who had unobtainable sensory nerve action potentials in digit I nerves. This method may serve as an adjunctive technique in the diagnosis of CTS. Its diagnostic sensitivity was high in comparison with other testing methods.
对50例疑似腕管综合征（CTS）患者和40名健康人进行了掌皮支（PCB）和示指神经感觉神经传导的比较。异常定义为潜伏期和感觉神经传导速度（SNCV）的差异超过对照组平均值加2.5个标准差。比较这两条感觉神经，在其感觉潜伏期的83.7%（43例患者中的36例）和SNCV的76.7%（43例患者中的33例）中发现了统计学差异。这排除了7例示指神经感觉神经动作电位无法获得的患者。该方法可作为CTS诊断的辅助技术。与其他检测方法相比，其诊断敏感性较高。
