OBJECTIVE
To compare the sensitivity of median sensory nerve conduction tests performed by stimulating digital branches in patients with carpal tunnel syndrome.
DESIGN
A prospective study in 506 hands of patients with carpal tunnel syndrome diagnosed electrophysiologically.
RESULTS
The sensitivity of median sensory nerve conduction tests across the first three digit-to-wrist segments and palm-to-wrist segment was determined. The most common abnormal electrophysiologic finding was the slowing of sensory nerve conduction velocity over the palm-to-wrist segment, which was detected in 98.5% of the hands. Slowing of sensory nerve conduction velocity over the digit 1-, 2-, and 3-to-wrist segments of the median nerve was found in 95.4%, 88%, and 82% of the hands, respectively.
CONCLUSION
The sensory nerve conduction velocity test of the digit 1-to-wrist segment has the most sensitivity among the three digital branches of the median sensory nerve, and it may be used more widely in the electrodiagnosis of carpal tunnel syndrome.
目的
比较刺激指神经分支进行的正中神经感觉神经传导测试在腕管综合征患者中的敏感性。
设计
对506例经电生理诊断为腕管综合征患者的手部进行前瞻性研究。
结果
确定了正中神经感觉神经传导测试在前三个手指至腕部节段以及手掌至腕部节段的敏感性。最常见的异常电生理表现是手掌至腕部节段感觉神经传导速度减慢，在98.5%的手部中检测到。正中神经第1、2和3指至腕部节段感觉神经传导速度减慢分别在95.4%、88%和82%的手部中发现。
结论
正中神经感觉神经第1指至腕部节段的感觉神经传导速度测试在正中神经的三个指神经分支中敏感性最高，可更广泛地用于腕管综合征的电诊断。
