Early stage of fracture Within 1 to 2 weeks after the injury, the affected limb is locally swollen and painful, easily displaced again, and the tendons and bones are in the repair stage. The purpose of practicing during this period is to eliminate stasis and swelling, and to strengthen the circulation of qi and blood by making the muscles of the affected limb do stretching and contracting activities, but the upper and lower joints of the fracture are inactive or slightly active. For example, in the case of forearm fracture, you can do fist grasping and finger extension and flexion activities, while the upper arm only does muscle stretching and contraction activities, while the wrist and elbow joints do not move. In the case of lower limb fracture, quadriceps muscle stretching and ankle extension and flexion activities can be done. The healthy limbs and other joints of the body should also be practiced, and bedridden patients should also strengthen deep breathing exercises and combine with self-massage. When practicing gong, the affected limb should be driven by the healthy limb, and the number of times should be from less to more, the time from short to long, and the amplitude of activities from small to large, so that the affected area is not painful, and any rough passive activities should be avoided. In the middle of the fracture period, after 2 weeks, the swelling of the affected limb basically decreases, the local pain gradually disappears, the stasis is not yet gone, new bone is born, and the fracture part becomes more and more stable. The purpose of practicing gong during this period is to strengthen the ability to remove stasis and create new bone, and to prevent local tendon atrophy, joint stiffness and systemic complications. In addition to continuing the muscle relaxation and contraction activities of the affected limb, the form of gong practice activities should also include gradually moving the upper and lower joints of the fracture part with the help of medical personnel. The movements should be slow and the range of activities should be small to large, and the number of activities should be increased and the amplitude and force of movements should be increased when clinical healing is approaching. For example, in the case of femoral stem fracture, under splinting and continuous traction, activities such as arm bracing and hip lifting, leg lifting and flexion, hip and knee extension and flexion can be performed; in the case of thoracolumbar fracture, activities such as flying swallow pointing and five-point support can be performed. The fracture has been clinically healed and the clamping has been released, but the tendons and bones are not firm and the limb function has not been fully recovered. The purpose of practicing gong in this period is to recover the joint function and muscle strength of the affected limb as soon as possible, so as to achieve strong tendons and bones and smooth joints. The method of gong practice is often taken in sitting and standing positions, with emphasis on strengthening the activities of the joints of the injured limbs, such as the practice of various movements for the upper limbs and weight training for walking for the lower limbs. Hot ironing and fumigation can be carried out at the same time during the practice. Some patients who have difficulty in functional recovery or have stiff joints can be combined with massage and tui-na techniques to help achieve the purpose of blood circulation and tendon activation.
