Abstract

An optical rear projection device, coupled with a video dimensional analyzer (VDA) system, was developed for simultaneous measurement of tensile strains on opposite surfaces of tendons and ligaments. Stress-strain behaviors of the tissue based on the strains measured on either surface were determined and compared. Data obtained from canine femur-medial collateral ligament-tibia complexes (FMT) and isolated chicken flexor tendons revealed that the strains on opposite surfaces of these parallel fiber soft connective tissues were similar during a uniaxial tensile test.

摘要

一种与视频尺寸分析仪（VDA）系统相结合的光学背投装置被开发出来，用于同时测量肌腱和韧带相对表面的拉伸应变。基于在任一表面测量的应变来确定并比较组织的应力-应变行为。从犬股骨-内侧副韧带-胫骨复合体（FMT）和分离的鸡屈肌腱获得的数据表明，在单轴拉伸试验期间，这些平行纤维软结缔组织相对表面的应变是相似的。
