There exists a good correlation between the measured electrical activities and isometric twitch tension in the cat soleus muscle during synchronous stimulation. For an unbiased sampling of electrical activities by averaging a number of electromyograms over the muscle concerned, a relation of the form E = 0.98T + 5.35 has been established. It is hoped that this relation will prove valuable in clinical application where EMGs are used. Electrode types for EMG pick-up differ in terms of the signal recorded due to the difference in the spatial and temporal addition of individual motor unit firing and the constructional difference of the electrodes. Fine wire pairs are the best for linearity and ease of application. Whe surface electrodes are used because of their non-invasive nature, care must be exercised to established the exact relation between EMG and tension. EMG recordings from different sites within a muscle show considerable variation. A more reliable measure can be obtained by external averaging of multiple pairs of electrodes.
在同步刺激期间，猫比目鱼肌中测量到的电活动与等长收缩张力之间存在良好的相关性。为了通过对相关肌肉上的多个肌电图进行平均来无偏采样电活动，已经建立了E = 0.98T + 5.35这种形式的关系。希望这种关系在使用肌电图的临床应用中被证明是有价值的。用于肌电图采集的电极类型因个体运动单位放电的空间和时间叠加差异以及电极结构差异而在记录的信号方面有所不同。细线对在线性度和应用便利性方面是最好的。当由于其非侵入性而使用表面电极时，必须小心确定肌电图与张力之间的确切关系。来自肌肉内不同部位的肌电图记录显示出相当大的差异。通过多对电极的外部平均可以获得更可靠的测量值。
