我们在OPENSIM中开发并验证了一个完整的胸腰椎关节模型，包括单个椎骨、肋骨和胸骨。为了确保模型中的躯干肌肉准确地代表体内的肌肉，我们使用了一种新的方法来调整肌肉横截面积（CSA）和位置，使用计算机断层扫描（CT）扫描从基于社区的队列中采样的躯干。椎体压缩载荷和躯干肌张力的模型预测与先前的椎间盘内压力（IDP）、遥测植入物的椎体载荷和肌电图（EMG）记录的躯干肌肌电活动的体内测量高度相关。
We developed and validated a fully articulated model of the thoracolumbar spine in OPENSIM that includes the individual vertebrae, ribs, and sternum. To ensure trunk muscles in the model accurately represent muscles in vivo, we used a novel approach to adjust muscle cross-sectional area (CSA) and position using computed tomography (CT) scans of the trunk sampled from a community-based cohort. Model predictions of vertebral compressive loading and trunk muscle tension were highly correlated to previous in vivo measures of intradiscal pressure (IDP), vertebral loading from telemeterized implants and trunk muscle myoelectric activity recorded by electromyography (EMG).
