“The third movement allowed at the ankle joint is supination, which is done by gliding at the subtalar joint, as well as by gliding at the joints between the talus and the calcaneus and navicular bones. This movement is quite free and can be overdone in poses like Padmasana if you go into the pose by pulling on your foot instead of keeping the ankle in neutral and placing the ankle on the opposite thigh. The ability to supinate easily can lead to a sprain of the lateral collateral ligaments of the ankle. Inversion of the foot often accompanies supination of the ankle.
The fourth movement of the ankle is pronation,”引自 第10章 踝关节和脚 - 人体运动学
