Human first dorsal interosseous muscle was stimulated tetanically using several levels of percutaneous electrical current which produced forces in the muscle-tendon complex of between 30% and 100% of maximum. During the tetanus the muscle was subjected to a small fast stretch. The ratio of the force response to the displacement of the muscle-tendon complex gave a measure of the stiffness of the total complex. An adaptation of the method of Morgan (1977) allowed the stiffness to be separated into two components the stiffness of the muscle fibres and the stiffness of the tendon. The results showed that at full activation the stiffness of the muscle fibres and the tendon are approximately the same. The normalised stiffness values obtained in the experiments compared well with animal data.
使用几种经皮电流水平对人类第一背侧骨间肌进行强直刺激，这些电流在肌腱复合体中产生的力量介于最大值的30%至100%之间。在强直收缩期间，肌肉受到一个小的快速拉伸。力反应与肌腱复合体位移的比率给出了整个复合体刚度的度量。对摩根（1977年）方法的一种改进使得可以将刚度分为两个成分，即肌纤维的刚度和肌腱的刚度。结果表明，在完全激活时，肌纤维和肌腱的刚度大致相同。实验中获得的归一化刚度值与动物数据比较良好。
