摘　　要：目的分析三重刺激技术（TST）诊断良性单肢肌萎缩症（BMA）的相关指标，评估该技术诊断BMA的指导价值。方法采用随机对照分析方法，对15例BMA患者和15名健康人进行TST检测，记录刺激引出的复合肌肉动作电位（CMAP）、运动诱发电位（MEP）潜伏期、波幅、面积和负波时限，分析TST波幅和面积衰减比值。结果BMA患者和健康人的TST波幅、面积衰减比值比较，差异均有统计学意义（P〈0．001）；BMA患者的TST波幅、面积衰减比值均明显低于健康人。结论TST在诊断BMA中具有一定的神经电生理指导价值。Objective To assess the diagnostic value of a triple stimulation technique （TST） for benign monomelic amyotrophy （BMA）. Methods A total of 15 BMA patients and 15 healthy control subjects were examined with the TST. The latent periods, amplitudes, areas and durations of the negative waves of the compound muscle action potential （CMAP） and motor evoked potential （MEP） induced by the stimulation were recorded, and the decreasing ratio of amplitudes and areas in the two groups were analyzed. Results There were significant differences in amplitude and area ratios between the BMA patients and the healthy control subjects. Both ratios were significantly lower in the BMA patients. Conclusion TST has some value in diagnosis of BMA.
