In vivo strain measurements at 8 locations on the tibia of the goat were performed. Successive in vitro calibrations were used to determine the assumed linear relationship between the measured strain signals and the external loads (3 forces and 3 moments) at the tibia. For the reconstruction of the in vivo external loads from the strain data, a transformation matrix was created from the calibration experiments, using 'singular-value decomposition'. The method is a reliable technique for measuring in vivo loads during functional gait and gives reproducible results.
在山羊胫骨的8个位置进行了体内应变测量。通过连续的体外校准来确定测量的应变信号与胫骨处的外部载荷(3个力和3个力矩)之间假定的线性关系。为了从应变数据重建体内外部载荷,利用“奇异值分解”从校准实验中创建了一个变换矩阵。该方法是一种测量功能性步态期间体内载荷的可靠技术,并且能给出可重复的结果。
