Abstract

Ankle-foot orthoses (AFOs) can improve walking mobility in individuals with calf muscle weakness, but their impact on sit-to-walk, a common daily activity, is underexplored. Using predictive simulations, we tested the effects of AFO stiffness on sit-to-walk in case of different degrees of plantarflexor weakness. Results showed that AFO stiffness significantly affects sit-to-walk kinematics and kinetics, with an optimal stiffness for minimizing effort. This optimum stiffness depends on severity of weakness and seat height. These findings emphasize the need to assess and consider the effects of AFO stiffness in daily life activities besides walking.

踝关节足矫形器刚度对坐姿-步行运动影响的预测模拟研究。

踝足矫形器（AFOs）可以改善小腿肌肉无力患者的行走能力，但其对日常活动“坐转走”的影响尚未得到充分研究。使用预测模拟，我们测试了在不同程度的跖屈肌无力的情况下，AFO刚度对坐姿-行走的影响。结果表明，AFO刚度显著影响坐姿到步行的运动学和动力学，具有最小努力的最佳刚度。这种最佳刚度取决于弱点的严重程度和座椅高度。这些发现强调需要评估和考虑AFO僵硬在日常生活活动中的影响，而不是步行。

期刊介绍： The primary aims of Computer Methods in Biomechanics and Biomedical Engineering are to provide a means of communicating the advances being made in the areas of biomechanics and biomedical engineering and to stimulate interest in the continually emerging computer based technologies which are being applied in these multidisciplinary subjects. Computer Methods in Biomechanics and Biomedical Engineering will also provide a focus for the importance of integrating the disciplines of engineering with medical technology and clinical expertise. Such integration will have a major impact on health care in the future.
