After a patient undergoes lumbar spine or artificial joint replacement surgery, he or she has the necessary conditions to improve spine or joint function, but to obtain better spine or joint function, a series of systematic and progressive rehabilitation training is needed to achieve it, because no surgery is the whole treatment. At the same time, rehabilitation can also promote improved cardiopulmonary function, gastrointestinal function and a return to the enjoyment of life. In addition, the degree of improvement in joint function depends on the patient’s pre-surgical joint function. Often, the surgeon will encourage the patient to use his or her “new” joint as soon as possible after surgery, but initially with the help of crutches, for example. Many patients experience periodic pain after joint replacement because the muscles around the joint have atrophied due to disuse and are not adequate for movement, and because the surrounding soft tissues have not yet healed. However, this pain will gradually disappear after a few weeks or months. Functional exercise is an important part of post-operative orthopedic rehabilitation. The patient’s surgeon and rehabilitation therapist will develop an appropriate functional exercise program based on the patient’s surgery and physical condition. With proper rehabilitation, the patient can still play golf, walk and dance after the artificial joint replacement, except for strenuous sports such as tennis or running. Three principles of rehabilitation training: The principle of individualization Each patient has a different disease, physical condition, and surgical procedure, so you should develop an exercise program that best suits your needs. The principle of gradual progress Do not think that you will wake up from surgery and have the ability to move your joints normally, as rehabilitation plays a very important role in this. Any over-activity is an injury and will affect the training effect. Principles of whole-body training While functional training of the joints is important, whole-body training is also indispensable. The human body is a complex machine, only when all parts are kept in good condition, the whole machine can work well. Rehabilitation training three elements: 1, confidence Rehabilitation training is hard, especially at the beginning, must be full of confidence in themselves. 2, persistence Rehabilitation training for patients with artificial joint replacement and spinal surgery is not a temporary activity, it is necessary to persist in the long term, have persistence. 3.Safety Safety is always the first priority. Falls can sometimes have very serious consequences. Therefore, care should be taken when performing any rehabilitation exercises. Particular attention is needed in the early post-operative period, and someone must accompany you to perform it.
