With severe burns, most patients have varying degrees of scar growth after wound healing, resulting in large joint dysfunction, which can cause physical disability in severe cases and affect life and work. Therefore, as the attending physician must pay attention to the concept of early rehabilitation, while educating the family and patients on relevant knowledge and obtaining their active cooperation, then the Yuanqi long-term effect will be significantly different. In the early stage of burn injury, active rehabilitation exercises determine the functional status of the wound after healing. I have encountered a case of lower extremity burns, the trauma is deep second degree, treated in the basic county hospital, because of pain, afraid to straighten the knee joint, and the doctor did not pay attention to this, about 10 days later came to me for consultation when the knee joint flexion 90 °, can not walk upright, the whole body is bowed back flexion, seriously affecting the quality of life. I did not rush to treat this patient’s trauma, but explained his condition and helped him straighten his knee first, and it took nearly an hour to straighten his lower limb alone. After several changes of medication, the patient was discharged from the hospital with standardized anti-scarring treatment and continued to run his construction site without any impact on joint function. At the same time, remind the patient and family members, early must cooperate with the doctor to carry out functional exercises, step by step, even if you can’t lift the leg in the early stage, you can have the intention to lift the leg and carry out muscle contraction just fine, then lift the leg and gradually extend the lifting time; wrap allows, early move the joint, these can have a decisive impact on the future functional recovery. Be sure not to be lazy for fear of pain, or other reasons!
