technical field

The invention relates to the field of medical machinery, in particular to an auxiliary dynamic rehabilitation support after joint surgery.

Background technique

Rehabilitation training generally refers to physical activities that help to restore or improve physical function after injury. Except for serious injuries that require rest treatment, general injuries do not require complete physical exercise. Appropriate and scientific physical exercises can promote Healing of injuries and promoting the recovery of various skills of the body have a positive effect on the recovery of the body.

After a joint operation and a period of rest and treatment, it is necessary to restore the muscles and nerves of the body to a healthy state. The necessary limb movement exercises are indispensable. Nowadays, most of the hospitals commonly use the patient's self-control and perseverance. During rehabilitation training, due to the long-term inactivity of the body, the nerves and muscles forget the state of exercise. When the patient is unable to control himself and does not have the willpower to persist in completing the rehabilitation exercises in the previous stage, the final physical function of the patient will be affected. The brace only plays a role in protecting and fixing the leg, and cannot really assist in rehabilitation.
