Quantitative electromyographic (QEMG) data recorded with two levels of threshold for the apparatus are compared. Using a fixed fraction of a subject's maximum effort the data are shown to be independent of sex, age and the strength of the muscles. The diagnostic yield of such a method is shown to be better with 50 muV threshold for analysis than with 100 muV, in cases of muscle disorders such as Duchenne muscular dystrophy and polymyositis. However, in cases of neurogenic lesions due to anterior horn cell disease the diagnostic yield remains the same with both thresholds.
比较了用该仪器的两个阈值水平记录的定量肌电图（QEMG）数据。使用受试者最大努力的固定比例，数据显示与性别、年龄和肌肉力量无关。在杜兴肌营养不良症和多发性肌炎等肌肉疾病中，这种方法在分析阈值为50微伏时的诊断率比100微伏时更好。然而，在前角细胞疾病导致的神经源性病变中，两种阈值下的诊断率保持相同。
