Thoracolumbar spine model with physiological functional spinal units

We presented a novel model of level-specific, nonlinear functional spinal stiffness and integrated this model in an existing rigid-body model of the thoracolumbar spine (https://simtk.org/projects/spine_ribcage). Also stiffening effects of compressive loading and thoracic spine interaction were successfully integrated. All 6-DoF of the intervertebral joints spanning from T1 to S1 were enabled.The stiffness formulations are comprehensive enough to capture the physiological response of spinal kinematics under various loading conditions, and are also simple and generic enough to be used for various spine modelling studies.For more information, please see our paper: Implementation of physiological functional spinal units in a rigid-body model of the thoracolumbar spine.

本研究提出了一种新颖的基于特定节段非线性功能脊椎刚度的模型，并将该模型与现有的胸腰椎刚体模型（https://simtk.org/projects/spine_ribcage）进行了整合。同时，成功地将压缩载荷的硬化效应和胸椎相互作用纳入模型之中。实现了从T1至S1的椎间关节的六个自由度。该刚度公式的构建既全面，足以捕捉脊椎运动学在不同加载条件下的生理反应，又简洁通用，适用于各种脊椎建模研究。更多详细信息，请参阅我们的论文：《胸腰椎刚体模型中生理功能脊椎单元的实施》。《生物力学杂志》。https://doi.org/10.1016/j.jbiomech.2019.109437。本项研究涉及的软件/数据包包括：
