This paper describes a device used to measure the isometric forces generated during electrical stimulation of the canine latissimus dorsi muscle in vivo with a preserved neurovascular supply. This device uses 2 strain gauge force sensors linked to a movable alignment frame to which the muscle is attached. The muscle length is controlled by the application of known weights to the system. The device has a frequency of response of 17.5 Hz and compliance of approximately 0.1 mm N(-1), and its experimental performance was tested in the anesthetized mongrel dog.
本文描述了一种用于在体内测量犬背阔肌在电刺激过程中产生的等长力的装置，该肌肉的神经血管供应保持完整。该装置使用两个应变片式力传感器，它们连接到一个可移动的对准框架上，肌肉附着在该框架上。肌肉长度通过向系统施加已知重量来控制。该装置的响应频率为17.5Hz，柔度约为0.1mm N⁻¹，并且在麻醉的杂种狗身上测试了其实验性能。
