A new method of loading the lumbrical muscle in the cadaver hand, based on the bicycle brake cable concept, has been developed. The device can be inserted with the aid of tendon-tunneling forceps and sutured to the profundus tendon at the origin of the lumbrical muscle. Lumbrical function is stimulated by applying a force that approximates the attachment point on the profundus tendon to the lateral wing of the extensor expansion without predetermining which will move the origin, the insertion, or both. This preliminary study reports the use of this device in determining lumbrical length changes in five fresh cadaver hands as the index finger was passively moved through each of six standard finger positions. In the absence of other restraints lumbrical contraction causes the index finger to move from the claw position through the straight to the intrinsic position. The latter position represents maximum shortening.
基于自行车刹车线概念，已开发出一种在尸体手上加载蚓状肌的新方法。该装置可借助肌腱隧道钳插入，并在蚓状肌起点处缝合至指深屈肌腱。通过施加一种力来刺激蚓状肌功能，该力使指深屈肌腱上的附着点接近伸肌扩张部的侧翼，而无需预先确定是使起点、止点还是两者移动。这项初步研究报告了在五只新鲜尸体手上使用该装置来确定当食指被动移动通过六个标准手指位置时蚓状肌长度的变化。在没有其他限制的情况下，蚓状肌收缩会使食指从爪形位置移动到伸直位置再到固有位置。后一位置代表最大缩短。
