In 5 adult sheep the psoas muscle of one side was electrically stimulated through the muscle nerves with an implantable stimulation unit for more than 5 weeks. In the final experiments the isometric tetanic tension of the stimulated muscles was reduced to 50-70% of the contralateral normal muscle. The use of only 15 Hz as a stimulation frequency led to a transformation of the originally fast muscle into a slow muscle with more resistance to fatigue. Future application of the chronically stimulated psoas muscle for driving artificial organs is discussed.
在5只成年绵羊中，使用植入式刺激装置通过肌肉神经对一侧腰大肌进行电刺激超过5周。在最后的实验中，受刺激肌肉的等长强直张力降低至对侧正常肌肉的50%-70%。仅使用15赫兹作为刺激频率会使原本的快肌转变为抗疲劳能力更强的慢肌。文中还讨论了长期受刺激的腰大肌在驱动人工器官方面的未来应用。
