Description

Technical Field

[0001] The utility model relates to the field of medical equipment, in particular to an ankle rehabilitation device. Background Art

[0002] The ankle is an important joint in the human body, bearing the weight of the entire body. It is also the most vulnerable part to injury. Once the ankle is injured, timely and appropriate cold compress therapy can help the ankle recover quickly and eliminate swelling and pain. In the later stages of rehabilitation, hot compress therapy is also needed to assist in promoting blood circulation and removing blood stasis, thereby accelerating the recovery process. At the same time, during the ankle rehabilitation process, in order to avoid local muscle atrophy caused by long-term inactivity and to ensure that the ankle joint returns to normal, ankle exercise training should be performed regularly. Due to the special location of the ankle, standing and walking should be avoided after injury to prevent human body pressure from causing secondary injury to the ankle. Therefore, auxiliary training equipment is needed.
