OBJECTIVES
The diagnostic utility and reliability of an easy-to-operate novel handheld nerve conduction tester in carpal tunnel syndrome (CTS) were evaluated.
MATERIALS AND METHODS
Using the test device, the sensory nerve conductions (SNC) in the median and ulnar nerves were compared with each other in 194 patients with suspected CTS and 95 healthy controls. The test device results were compared with the results of nerve conduction studies (NCS) with traditional instrumentation.
RESULTS
The new device correctly classified 145 of the 149 hands (97.3%) without median nerve lesion and 171 of the 200 hands (85.5%) with median nerve lesions in traditional NCS. The specificity of the new tester compared with traditional instrumentation was 98%. The correlation coefficient for different technicians in different studies was 0.87.
CONCLUSIONS
The findings obtained with the new tester in CTS were reliable and reproducible. This tester may increase availability of NCS in CTS.
目的
评估一种易于操作的新型手持式神经传导测试仪在腕管综合征（CTS）中的诊断效用和可靠性。
材料与方法
使用该测试设备，对194例疑似CTS患者和95例健康对照者的正中神经和尺神经的感觉神经传导（SNC）进行相互比较。将测试设备的结果与传统仪器进行神经传导研究（NCS）的结果进行比较。
结果
在传统NCS中，该新设备正确分类了149只无正中神经病变手中的145只（97.3%）以及200只有正中神经病变手中的171只（85.5%）。与传统仪器相比，新测试仪的特异性为98%。不同研究中不同技术人员的相关系数为0.87。
结论
在CTS中使用新测试仪获得的结果可靠且可重复。该测试仪可能会提高CTS中NCS的可用性。
