摘　　要：目的:探讨蚓状肌-骨间肌法对腕管综合征(CTS)的诊断作用。方法:临床症状和体征符合CTS的患者55例(84侧)和年龄性别匹配的正常对照组50例(50侧)。采用蚓状肌-骨间肌法测定蚓状肌(2L)和骨间肌(I)潜伏期(DML)及其差值(2LIDMLD),并与正常对照组比较。此外常规记录患者正中神经和尺神经的感觉、运动传导速度。结果:正常对照组和CTS组2LIDMLD平均值及范围分别为0.13±0.07ms、1.07±0.55ms,CTS组与正常对照组比较,差异有显著性意义(P<0.01)。蚓状肌-骨间肌法和常规的正中神经感觉传导速度(SCV)检测CTS,阳性率分别为85.71%和63.09%。结论:2LIDMLD是诊断CTS的敏感的的电生理指标,蚓状肌-骨间肌法为一种快捷方便、诊断敏感的神经电生理检测方法。Objective：To evaluate the diagnostic value of second lumbrical and interossei distal motor latency difference（2LIDMLD）in diagnosing carpal tunnel syndrome（CTS）.Methods：2LIDMLD was standardized in 50 hands of age-matched healthy controls.Subjects with clinically diagnosed CTS were prospectively evaluated with 2LIDMLD in addition to another standard diagnostic test.Sensitivities of these two tests were compared in patients with CTS.Results：Eighty-four hands of 55 patients met the clinical criteria for CTS.The mean values of 2LIDMLD of healthy controls and CTS group were 0.13 ±0.07ms and 1.07 ±0.55ms,respectively.The prolonged 2LIDMLD for the CTS patients had significant differences as compared with that of normal subjects（P0.01）.Sensitivity of 2LIDMLD and conventional median sensory conduction velocity（SCV）in diagnosing CTS were 85.71% and 63.09%,respectively.Conclusion：2LIDMLD is a sensitive,also simple and convenient measurement in confirming the electrophysiologic diagnosis of CTS.
