Finger tendon rupture rehabilitation training includes muscle strength training, finger joint mobility training and dexterity training. 1. Muscle strength training: after the finger tendon rupture, early braking and resting is the main focus, with the local recovery, isometric contraction can be used for muscle strength training of the finger. After recovery and stabilization, muscle strength training can be started with isometric contraction. 2. Finger joint mobility training: the nodules recovered from finger tendon rupture may lead to soft tissue adhesion, affecting the range of motion. Therefore, as the tendon heals, it is necessary to train the mobility by actively contracting the finger joints and passively moving the finger joints. 3. Dexterity training: After the finger tendons have completely healed, finger dexterity training can be started, such as using the fingers to screw screws, playing the keyboard and typing, so as to improve finger dexterity, improve hand function and prevent sequelae. The above rehabilitation training should be carried out under the guidance of a professional rehabilitation physician. During the training process, attention should be paid to gradual progress to prevent re-injury of the finger tendons; if pain and swelling occur, feedback should be given to the physician in time to adjust the training program.
