| 摘 要： | 对９例强直性肌营养不良患者行激发重复神经电刺激检查。１例ＡＲＮＳ前见序列复合肌肉动作电位波幅递减，８例ＡＲＮＳ后出现首位ＣＭＡＰ波幅降低，其中６例伴序列ＣＭＡＰｓ波幅递减。首位ＣＭＡＰ波幅降低出现率和平均降低程度随病程延长而加重。

| Abstract: | ARNS studies were made on 9 cases of MyD,8 cases (89%) showed decrease in amplitude of first compound muscle action potential (CMAP) which represented all CMAPs.And among them 6 cases showed declining response in amplitude of train CMAPs.The appearance rate of decrease in amplitude and the severity of mean decrement were related to the durations of the disease.We conjecture that the skeletal muscles of MyD have changes in excitability and contractility,and that these changes may be caused by the decreace in the number of normal muscle fibers.The declining response of MyD was different from myasthenia gravis. |
