The technique of automatic analysis of the electromyogram is reviewed in detail. Observations on new series of healthy subjects which may serve as a control series for comparisons with subjects with neuromuscular disease are reported. The advantages to clinical practice of using fixed standard loads for the examination are stressed. Increase in the mean amplitude of the interference pattern wasfound with increasing age in biceps brachii and tibialis anterior (but not in vastus medialis). There was no corresponding increase in mean turns count. It is suggested that this change is due to increasing mild chronic partial denervation in these 2 muscles with advancing age.
详细回顾了肌电图自动分析技术。报告了对新的健康受试者系列的观察结果，这些结果可作为与神经肌肉疾病患者进行比较的对照系列。强调了在检查中使用固定标准负荷对临床实践的益处。肱二头肌和胫前肌的干扰模式平均振幅随年龄增长而增加（但股内侧肌没有）。平均转折计数没有相应增加。有人认为，这种变化是由于随着年龄的增长，这两块肌肉中轻度慢性部分去神经支配增加所致。
