A device is presented to measure the range of independence, and the force transfers between the deep flexor tendons of different fingers. These force transfers result from the coactivation of the individual deep flexors, or the stretching of anatomical interconnections between the individual muscle bellies or tendons. In the quantification of the forces in the deep flexor end tendons, errors may occur due to (involuntary) forces in the extensors and superficial flexors. These errors are investigated by modelling the distal interphalangeal joint equilibrium equation, and illustrated by measuring results. They can be avoided by appropriate instrumental design, and proper finger positioning during measurement.
本文介绍了一种用于测量独立性范围以及不同手指深屈肌腱之间力传递的装置。这些力传递是由各个深屈肌的共同激活,或者各个肌腹或肌腱之间解剖学连接的拉伸引起的。在量化深屈肌腱末端的力时,由于伸肌和浅屈肌中的(非自愿)力,可能会出现误差。通过对远侧指间关节平衡方程进行建模来研究这些误差,并通过测量结果进行说明。可以通过适当的仪器设计和测量过程中正确的手指定位来避免这些误差。
