We have quantified the pattern of electrical muscle activity at a force of 0.3 kg, 30% of maximum force, and maximum force in the abductor pollicis brevis muscle of 21 patients with neurogenic disorders (10 with carpal tunnel syndrome, 9 with polyneuropathy and 2 with motor neurone disease) and of 15 normal subjects. In normal subjects, the number of turns, the mean amplitude and the ratio between them were independent of maximum force, age and sex of the subjects. In 21 patients with neurogenic disorders, the cumulative diagnostic yield of the analysis of the pattern of electrical activity was 86% compared to the diagnostic yield of the mean duration and mean amplitude of individual motor unit potentials of 90%. These diagnostic yields in a small distal muscle were of the same order as those of the brachial biceps muscle in previous studies.
我们对21例神经源性疾病患者（10例腕管综合征、9例多发性神经病和2例运动神经元病）及15名正常受试者的拇短展肌在0.3千克力（最大力的30%）和最大力时的肌肉电活动模式进行了量化。在正常受试者中，肌电活动的转折次数、平均幅度及其比值与受试者的最大力、年龄和性别无关。在21例神经源性疾病患者中，电活动模式分析的累积诊断率为86%，而单个运动单位电位的平均时限和平均幅度分析的诊断率为90%。在一个小的远端肌肉中的这些诊断率与先前研究中肱二头肌的诊断率处于同一水平。
