摘要
目的 :探讨三种神经传导方法在腕管综合征 (CTS)诊断中的应用价值。方法 :应用常规法、掌刺激法、短段刺激法对 4 3例根据临床表现怀疑为CTS的患者进行检测。结果 :常规法显示 4例正常 ,34例为CTS ,3例为周围神经病 ,2例为神经根性损害。掌刺激法显示 10例CTS传导减慢主要在经腕管段而不是掌到指节段 ,3例周围神经病患者则相反。短段刺激法显示 5例CTS在腕管段测得的潜伏期与腕管远端各段潜伏期差均大于 0 .5ms ,并发现 1例常规法检测结果错误。结论 :常规法是确诊CTS并明确其病变程度的重要手段。掌部刺激法有助于鉴别CTS与周围神经病。短段刺激法在诊断CTS时很可靠 。
Objective:To investigate the values of three nerve conduction determination methods in the diagnosis of carpal tunnel syndrome(CTS). Methods Three methods, i.e. routine, metacarpal stimulation and short segment stimulation methods, were used to test the suspected patients with CTS according to clinical manifestations. Results:The routine method showed normal in 4, CTS in 34, peripheral neuropathies in 3 and radioculopathy in 2. The metacarpal stimulation method showed that conduction velocity was slowed in carpal tunnel segment, not in metacarpi-fingers segment in 10 patients with CTS. The results were on the contrary in 3 patients with peripheral neuropathies. The short segment stimulation method showed in 5 patients the latency was lengthened more than 0.5ms in carpal tunnel segment, compared with the results in each segment distal to the carpal tunnel. In addition, the result of routine method was revealed wrong in one patient. Conclusion The routine method might provid an important means of confirming CTS and the extent of damage. The metacarpal stimulation method might be helpful in distinguishing CTS from peripheral neuropathies. The short segment stimulation method might be reliable, and have an advantage of determining distal sites of lesions.
