| 摘 要： | 目的研究腕管综合征(CTS)更敏感的电诊断指标,并结合电生理探讨CTS特征性体征与病变程度的关系。方法2009年2月～2010年2月间就诊于本科,符合纳入标准的CTS患者72例(121只腕)行神经传导检测(NCS),记录腕-拇短展肌/小指展肌末端运动潜伏期(DML)、拇短展肌复合肌肉动作电位(CMAP)波幅、腕-食指/环指/小指感觉传导速度(SCV)、正中/尺神经感觉潜伏期差(?DSL)和感觉神经动作电位(SNAP)波幅。结果(1)拇短展肌CMAP波幅(mV)低于小指展肌(7.40±3.25v.s.10.74±2.23,t=-9.22、P0.001),环指记录的正中神经SNAP波幅(μV)低于尺神经(9.77±7.46v.s.23.67±9.92,t=-10.70、P0.001);(2)腕-拇短展肌DML延长、腕-食指和腕-环指SCV减慢、?DSL增加,阳性率分别为89.1%(106/119)、79.6%(78/98)、85.1%(57/67)和95.5%(64/67)(χ2=9.66,P=0.022);(3)与阴性者比较,Tinel征阳性者DML(ms)延长更多(5.65±1.62v.s.4.89±1.61,t=2.13、P=0.035),Phalen征阳性者腕-食指SCV减慢更多(35.57±7.49v.s.39.84±7.66,t=-2.39、P=0.019),其余各参数均无差异(P0.05)。结论?DSL诊断CTS最敏感,怀疑CTS时可作为首选的方法;Tinel征和Phalen征不能完全反映CTS严重程度。

| Abstract: | Objective To investigate prospectively a more sensitive parameter of electrodiagnosis in carpal tunnel syndrome(CTS),and to explore the correlation between the characteristic signs and severity of CTS combined with electrophysiological findings.Methods Seventy-two consecutive CTS patients(121 wrists) who met the inclusion criteria were enrolled between February,2009 and February,2010.The enrolled subjects were electrophysiologically evaluated by nerve conduction studies(NCS),and the following parameters wer... |
