[0002] The foot is the end of the human movement link and is the only part of the body that directly contacts the ground during standing, walking, running and other actions, so the size of the foot muscle strength plays a crucial role in the static stability control and dynamic movement of the human body.

[0003] The foot muscles are divided into foot intrinsic muscles and foot extrinsic muscles. The foot intrinsic muscles have their tendon attachment points in the foot, so they mainly play a role in local stability.
