Functional exercises for finger joint stiffness after surgery mainly include passive training and active training. 1. Passive training: After surgery, due to the need to immobilize the affected limb for a period of time, joint stiffness may be caused after surgery. If the fracture heals and stabilizes, passive training of the fingers can be carried out. Passive training requires the extension and flexion of the finger joints, such as the proximal and distal joints, under the action of external force, in order to try to move the joints passively to the normal range of joint activity as a standard. 2. Active training: tendon, ligament, fracture patients, etc., four weeks after the operation, you can carry out active training of finger joints, such as rubber bands, elastic bands to stretch muscles, tendons and other soft tissues; empty-handed fist, grip to increase the muscles, tendons and other parts of the strength of the training, tying shoelaces, fasten the buttons and other hand fine motor training. Gradually increase the strength of all parts of the fingers as well as endurance.
