There is currently no validated full-body lifting model publicly available on the OpenSim modelling platform to estimate spinal loads during lifting. In this study, the existing full-body-lumbar-spine model was adapted and validated for lifting motions to produce the lifting full-body model. Back muscle activations predicted by the model closely matched the measured erector spinae activation patterns. Model estimates of intradiscal pressures and in vivo measurements were strongly correlated. The same spine loading trends were observed for model estimates and reported vertebral body implant measurements. These results demonstrate the suitability of this model to evaluate changes in lumbar loading during lifting.
目前在OpenSim建模平台上没有公开可用的经过验证的全身举重模型来估计举重过程中的脊柱负荷。在本研究中，对现有的全身腰椎模型进行了调整并针对举重动作进行了验证，以生成举重全身模型。该模型预测的背部肌肉激活与测量的竖脊肌激活模式密切匹配。模型对椎间盘内压力的估计与体内测量结果高度相关。模型估计和报告的椎体植入物测量结果观察到相同的脊柱负荷趋势。这些结果证明了该模型适用于评估举重过程中腰椎负荷的变化。
