Many studies concerning human balance use computational models that represent the body as a single, double, or triple inverted pendulum while ignoring the feet. Clinical research, however, has begun to more closely examine specific contributions of the feet in balance, leading to a disparity between the state of clinical research and the models used for simulation. Here, we expand the single inverted pendulum model by adding four additional rigid links to represent the feet. Model parameters, equations of motion, actuation based on human musculature, and control based on proprioception are discussed. Computation of ground reaction forces under the heel, forefoot, and toes is also addressed. Simulations focusing on the role of the toes and toe muscles in static balance and forward leaning are presented.
许多关于人类平衡的研究使用计算模型来表示人体为一个单一、双重或三重倒立摆，而忽略了脚。然而，临床研究已经开始更仔细地研究脚在平衡中的具体贡献，这导致了临床研究的状态和用于模拟的模型之间存在差距。在这里，我们通过添加四个附加的刚性连杆来扩展单倒立摆模型，以表示脚。讨论了模型参数、运动方程、基于人体肌肉的驱动以及基于本体感受的控制。还讨论了脚跟、前脚掌和脚趾下地面反作用力的计算。介绍了专注于脚趾和脚趾肌肉在静态平衡和前倾中的作用的模拟。
