本研究提出了一种新的方法，评估关节反作用力的运动分析，使用肌肉骨骼模型。虽然一般的肌肉张力估计最小化的肌肉张力的总和，所提出的方法利用关节反作用力本身的优化问题的目标函数，除了传统的方法。该方法可以估计使特定关节力最大化或最小化的肌肉张力的模式。作为一个典型的结果，所提出的方法允许评估椎间盘压缩力引起的肌肉的共同收缩，同时避免风险低估。以实际的举重运动为例进行了分析，验证了该方法能够估计不同张力条件下的肌肉张力分布。
This research proposes a novel method that evaluates joint reaction forces by motion analysis using a musculoskeletal model. While general muscle tension estimations minimize the sum of the muscle tensions, the proposed method utilizes the joint reaction forces themselves in the objective function of the optimization problem in addition to conventional method. This method can estimate a pattern of the muscle tensions that maximizes or minimizes a specific joint force. As a typical outcome, the proposed method allows evaluating intervertebral disc compressive force caused by co-contraction of muscles while avoiding risk underestimation. We analyzed the actual lifting motion as an example and confirmed that the method can estimate the muscle tension distribution under different tension conditions.
