[0002] The ankle joint is an important bone joint in the human body, with numerous foot joints and muscles attached to it. For people with limited movement, especially those who have lost the ability to move independently for a short or long period of time, long-term inactivity of the ankle joint can lead to a series of problems such as ankle joint function degeneration, joint effusion, and associated muscle atrophy.

The simple and stable bevel gear structure is used to change the transmission direction, drive the foot plate to carry loads and train the foot and ankle joint; the length of the telescopic support arm is adjustable to adapt to the calf size of different users; the magnetic binding part can easily connect the user's calf to the magnetic binding part; the emergency switch can control the operation of the power supply structure, achieve emergency shutdown more stably and quickly, and improve the safety of the foot and ankle joint trainer.

[0004] The existing announcement number CN118320381A discloses a foot and ankle training device, including a strap for positioning the foot and a foot support, an ankle support, and a calf support connected in sequence, wherein the angle α between the foot support and the ankle support is an acute angle, the ankle support is rotatably connected to the calf support, and the rear side of the calf support is provided with an elastic damping structure for contacting the calf support when worn; the present invention can not only solve the problem of foot drop without the need for motor drive, but also has high comfort and good experience; at the same time, considering the problem of convenient transportation, the calf support and the ankle support are rotatable, and the calf support and the elastic damping structure are in contact rather than connected, so when storing, the calf support can be directly rotated to store the foot support inside the calf support, which takes up little space and is convenient for storage and transportation.

[0005] In summary, existing ankle training devices generally perform front-to-back and up-and-down training, and do not have the function of combining twisting training, resulting in relatively poor training results. Therefore, we propose a ankle training device and method. Summary of the Invention
