摘　　要：目的　探讨运动单位电位 (MUP)多项参数对神经原性损害的诊断价值。方法　对 13例神经原性病变患者 ,采用棘波触发平均技术 ,得到股四头肌MUP2 19个 ,胫前肌MUP16 3个 ,拇短展肌MUP14 2个 ,对MUP多项参数进行定量分析 ,并与正常对照组进行对比分析。结果　各项参数与正常对照相比均有显著意义 (P <0 .0 0 1～ 0 .0 0 0 1) ,经 95 %可信限和均数 +2 .0标准差界值水平的显著性检验 ,证明SI、面积、波幅和WHI较其它参数具有较高的诊断敏感性。结论　SI与面积对神经原性损害的诊断作用最敏感 ,WHI与波幅的诊断作用次之 ,面积 /波幅与时限的诊断作用较小。Objective To study the diagnostic value of motor unit potential(MUP) multi parameters in neurogenic lesion.Method From the vastus medialis,tibialis anterior and abductor pollicis brevis muscles,219,163 and 142 numerical values of MUP were recorded in 13 patients with neurogenic diseases respectively.Multi parameters about MUP were analyzed quantitatively and compared with the normal values.Results Every parameters about MUP in neurogenic diseases had significant differences from the normal values.SI,area,amplitude and WHI were confirmed to have more important diagnostic value than the others by significance analysis of the 95% confidence level and +2.0s cut value between normal and neurogenic MUP.Conclusions SI and area are the most sensitive to diagnose the neurogenic diseases.WHI and amplitude have less important diagnostic value than them,but there was a little diagnostic value in the area/amplitude ratio and duration.
