A method for analysis of hand function is reported through evaluation and characterization of flexor digitorum profundus (FDP) tendon mechanics. A testing platform is used that allows for the dynamic evaluation of intact cadaver hand mechanics under normal and pathologic conditions using simultaneous measurements of tendon load, tendon excursion, grip strength, pinch strength, and joint angle. This study of FDP tendons in normal fresh cadaver hands demonstrates that FDP tendon excursion increases as the number and size of joints flexed increases. Extensor counterweighting 500 g, increases FDP tendon load and work but not excursion requirements, and FDP loads of up to 75 N are required for single finger grip strengths of 4 kg force. These loads do not result in permanent (plastic) deformation of either the tendon or the restraining soft tissues. Detailed descriptions of the platform and the mechanical tests performed are provided.
本文报告了一种通过评估和表征指深屈肌（FDP）肌腱力学来分析手部功能的方法。所使用的测试平台能够在正常和病理条件下，通过同时测量肌腱负荷、肌腱位移、握力、捏力和关节角度，对完整尸体手部力学进行动态评估。这项针对正常新鲜尸体手部FDP肌腱的研究表明，随着屈曲关节数量和大小的增加，FDP肌腱位移也会增加。施加500克的伸肌配重会增加FDP肌腱负荷和功，但不会增加位移需求，单指握力达到4千克力时，FDP负荷高达75牛。这些负荷不会导致肌腱或限制软组织发生永久性（塑性）变形。文中还提供了该平台及所进行力学测试的详细描述。
