Technical field

The invention relates to the technical field of rehabilitation training equipment, specifically an injury rehabilitation training device.

Background technique

The knee joint is the largest flexion joint in the body. At the same time, its shape also determines that it is not a very stable joint. Therefore, the ligament structure of the knee joint plays a big role in maintaining the normal function and stability of the knee joint. The knee joint Although it is a flexion joint, it can also perform slight grinding and rotation when bending the knee. In the process of daily exercise, the knee joint may be damaged accidentally, which will require knee joint injury rehabilitation training. The existing knee joint Rehabilitation training for joint injuries should include strength training for the muscles around the knee joint on the basis of minimizing wear and tear on the knee joint to enhance muscle strength and stabilize the knee joint.

However, in actual use, we found that most of the existing training equipment is used for exercises with the assistance of medical staff or family members, and is generally aimed at patients who already have a certain degree of mobility, such as helping patients with leg lifting exercises and half squat exercises. , and for some patients with severe knee joint injuries, they are usually in wheelchairs in the early stages, making it difficult to perform rehabilitation training on their own. The existing equipment is not suitable for patients with severe knee joint injuries, but these patients can Perform some small-scale exercises under the guidance of a doctor to improve the rehabilitation effect of the knee joint. If there is no matching training equipment, it will affect the patient's rehabilitation to a certain extent. For this reason, we propose an injury rehabilitation training device .
