摘要采用ANOPS-101微型计算机组成的自动化系统分析肌电。股内侧肌（VM）和肱二头肌（BB）肌肉进行了研究，在28名对照组，16例肌病患者，26例失神经病变。对于每一块肌肉，计算肌肉动作电位的持续时间和相位数的平均值;还测量了干扰图案中偏转的平均密度和振幅。在肌病中检测到的异常发生率高于神经性疾病;对于这两种情况，BB的发生率显著高于VM。对于去神经支配的诊断，最有用的测量是电位持续时间;对于肌病的检测，振幅测定也非常有用。目前的结果进行了比较与其他已发表的研究，其中自动肌电图分析已采用。
SUMMARY An automated system, incorporating the ANOPS-101 mini-computer, has been used to analyse the EMG. The vastus medialis (VM) and biceps brachii (BB) muscles were studied in 28 controls, 16 patients with myopathies, and in 26 patients with denervating disorders. For each muscle mean values were computed for the durations and numbers of phases of muscle action potentials; the mean density and amplitude of the deflections in the interference pattern were also measured. A higher incidence of abnormalities could be detected in myopathic than in neuropathic disorders; for both conditions the incidence was significantly greater in BB than in VM. For the diagnosis of denervation the most useful measurement was that of potential duration; for the detection of myopathies amplitude determinations were also very useful. The present results have been compared with those of other published studies in which automatic EMG analysis has been employed.
