Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation training equipment, in particular to an ankle joint rehabilitation trainer. Background Art

[0002] The ankle joint is composed of the tibia, fibula and talus. It is a hinge joint that mainly plays a weight-bearing role. It requires both a certain stability and flexibility during movement.

[0003] When the patient's ankle nerve is damaged due to various reasons, it can be divided into the following three situations:

[0004] 1. If the ankle joint is slightly injured, the patient can rehabilitate the ankle joint by walking on his own. During the walking rehabilitation process, it is necessary to ensure that the ankle bone will not be dislocated and the walking posture will not be deformed.

[0005] 2. Moderate injury to the ankle joint means that the patient can undergo walking rehabilitation, but will experience severe pain during the walking process.

[0006] 3. The ankle joint is severely injured, meaning the patient is unable to walk independently.

[0007] Existing ankle rehabilitation trainers can only solve minor ankle injuries. When the ankle is moderately or severely injured, they cannot meet the use requirements.
