For the evaluation and rehabilitation training of joint movement function disorders in patients with joint injuries, after the motor function is evaluated with the help of relevant evaluation aids, a rehabilitation training plan suitable for patients with joint injuries needs to be formulated.

[0003] When the wrist, elbow, knee, and ankle joints are injured, joint fixing braces are usually used to reinforce the joints of patients. In the process of rehabilitation training, in order to better fix the joints of patients and evaluate and analyze the rehabilitation, the joint fixing braces need to have an automatic adjustment function and a data recording and collection function. The existing joint fixing braces have simple structural functions and do not have the function of being used in combination with a sports rehabilitation evaluation system for rehabilitation training. During their use, usually, the brace can only be manually adjusted to a suitable angle or size according to the actual situation for multiple times so that rehabilitation personnel can carry out wearing training and evaluation, which easily causes secondary injuries to the rehabilitation personnel. In addition, during the sports evaluation and rehabilitation training, it is not convenient to record and analyze the rotation treatment angle data of the joint fixing brace, and it cannot form a closed-loop integrated intelligent evaluation training system with the movement function disorder evaluation training system.
