One month after surgery, this stage is mainly bed exercise, the initial training intensity is not easy to be too large, to do a good account with the patient’s parents, can focus on improving the strength of the quadriceps and low back, but also according to the specific patient situation to join the sitting balance, four-point kneeling and double knees straight and other balance training. This stage is the key period for the rehabilitation effect, because the patient has just gone through surgery, the physique is weak, three months training must be able to improve, you can add some homework such as (squatting and standing, etc.) let the patient’s family cooperate to complete, to communicate well with the patient’s family only by our PT 40 minutes It is not enough, usually also need parents to cooperate with the completion of some training, pay attention to account for good training intensity, so as to help improve the training effect 3 to 6 months after surgery this stage for the incremental period of strength, if the strength has improved can enter the standing balance and other training to correct abnormal posture, according to different children different progress and then different arrangements for training programs such as symptoms of the lighter children can enter the initial gait training. Knee recoil training causes: 1, the knee joint itself bony changes, resulting in abnormal knee joint position, 2, weight-bearing knee joint control ability is poor, joint relaxation, quadriceps and national rope muscle strength is weak. 3, when the muscle tone is high can also lead to knee hyperextension 6 to 9 months after surgery, this stage can be strengthened according to the patient’s different conditions balance and coordination training 9 to 12 months after surgery, this stage may be the platform period of rehabilitation training, the platform period is not much effect and progress, but in persistence, the same effect will be achieved, so this stage and the patient’s communication is particularly important, the patient’s family can understand the rehabilitation At the same time, some lighter patients can enter into higher physical fitness and posture correction training. One to two years after surgery, most patients can choose home rehabilitation according to the situation after entering gait training, and patients with heavy conditions should continue to insist on training. The training mentioned here is a few months to what extent what to practice is based on different analysis of the situation of different children, if the foundation is poor or uncooperative children, it will take more time to achieve the desired rehabilitation effect, we need to communicate more with the parents of the patients, to often explain to them the training situation of children, to get their approval and support.
