本研究的主要目的是研究继发于生理应力水平和运动范围降低或增加的软组织稳态反应是否是机械性能的变化或质量的变化，或两者兼而有之。两个实验动物研究。一个是通过固定兔膝关节进行的应力和运动剥夺研究，另一个是通过小型猪跑步运动进行的应力和运动增加研究。研究结果表明，应力和运动的变化显着改变了韧带和指伸肌肌腱的组织特性和质量。而手指屈肌腱的性质和质量没有明显变化。组织对应力和运动的反应差异的可能机制进行了讨论，应力和组织重塑之间的非线性关系的建议。
The primary goal of this investigation is to study whether soft tissue homeostatic responses secondary to decrease or increase in physiological stress levels and range of motion are a change of mechanical properties or a change of mass, or both. Two experimental animal studies are presented. One is a stress and motion deprivation study by immobilization of a rabbit knee, and the other is an increase in stress and motion study by running exercise of the miniature swine. The findings are that changes in stress and motion significantly altered the tissue properties as well as mass in the case of ligaments and digital extensor tendons. Whereas, no significant changes in properties and mass were detected for the digital flexor tendons. Possible mechanisms of the difference in tissue responses to stress and motion are discussed, and nonlinear relationships between stress and tissue remodeling are suggested.
