Abstract：
The paper deals with the torques of external muscles acting on the upper ankle joint under weight-bearing conditions and their importance in diagnosing and treating the human foot. Experimental data were collected and calculations were performed. Based on the experiments with the biomechanical model of the foot and upper ankle joint, it was shown how the changes in the force arms of the external muscles of the foot under weight-bearing conditions, change the torque. The real values of muscle forces and torques of the external muscles of the foot were calculated. Taking into account the distance of the lines of muscle action from the axis of rotation of the upper ankle joint the rotational force of the muscles was calculated. The influence of changing the force arm on the rotational efficiency of the muscle balancing the moment of gravity was shown. Knowledge of muscle torque under weight-bearing conditions is crucial for correctly assessing foot biomechanics. It has been shown that torque (gravitational and muscular), not pure force, is crucial when assessing the rotational capacity of the analyzed joint. A change in the approach to diagnostics and treating paresis or weakness of extrinsic foot muscles was proposed through the manipulation of the distance of their action line from the axis of joint rotation.
摘要：
本文讨论了在负重条件下作用于上踝关节的外部肌肉的扭矩及其在诊断和治疗人脚中的重要性。收集实验数据并进行计算。基于足部和上踝关节的生物力学模型的实验，它显示了在负重条件下脚的外部肌肉的力臂的变化，改变扭矩。计算了足部外部肌肉的肌肉力和扭矩的实际值。考虑到肌肉动作线与上踝关节旋转轴的距离，计算了肌肉的旋转力。显示了改变力臂对平衡重力力矩的肌肉旋转效率的影响。了解负重条件下的肌肉扭矩对于正确评估足部生物力学至关重要。它已经表明，扭矩（重力和肌肉），不是纯粹的力量，在评估被分析关节的旋转能力时至关重要。通过操纵其动作线与关节旋转轴的距离，提出了诊断和治疗足外肌肉麻痹或无力的方法的改变。
