In modern society, people always want to be flawless, however, various traumas, burns, surgeries, infections, injections, etc. can cause skin scarring, which can affect the appearance in minor cases and function in serious cases, and even endanger lives. Scars, medically known as “keloid scars”, can occur on any part of the body, causing uneven skin surface, pigmentation, redness, etc., affecting the appearance, as well as itching, pain and discomfort, breaking and other symptoms, and in severe cases, joint contracture and deformity can occur. Some abnormal and harmful scars may become cancerous and affect the patient’s life, but cancerous scars are rare after all, and most of them are physiological and normal. Doctors often say, “The scar is ugly because you are a keloid”, as if the keloid is the “culprit” of the scar. In fact, keloid is very rare and the key points are keloid scars and family genetic traits. Keloid scars are crabfoot-shaped; they have persistent growth, redness, itching and other clinical symptoms, and do not subside on their own, and are prone to recurrence after surgical excision alone, and the scope of recurrence can exceed the original scar. Therefore, the diagnosis of keloid needs to be very careful, and there is no need for patients to let the “keloid” hat weigh heavily on their minds. Unfortunately, it is almost impossible to completely eliminate a scar that has already grown. According to the existing medical technology can only reduce the serious scar, make the obvious ones become inconspicuous, and minimize the harm of scar. There are many treatments for skin scarring, and traditional treatments such as surgery and medication have difficult problems such as high recurrence rates and adverse reactions. It can be said that there is no special treatment for scar, so the prevention of scar is more important than scar treatment to a certain extent. Studies have shown that timely and effective use of compression therapy, topical silicone gel, and various physical factors to treat the wound in the early stage of trauma can effectively prevent or reduce the proliferation of keloid scars. In the treatment of scar formation period, the current more effective physical therapy methods mainly include computerized medium frequency and computerized ultrasound. Depending on the specific conditions of the scar, two to three methods with fewer side effects and easy to use can be used for comprehensive prevention and treatment, which is more effective than a single method. In addition, effective and reasonable rehabilitation treatment can further reduce scarring and improve function. During the recovery period, passive activities can pull the contracted and adhered joints, improve the mobility of joints and relax the contracted scar. Massage is one of the main measures of passive activities, through massage, massage, pulling and other methods, to restore a certain degree of joint mobility, creating good conditions for active activities. On the basis of passive activities, active activities can be exercised with various instruments, which can mobilize the patient’s enthusiasm and promote comprehensive physical and mental rehabilitation. Traditional Chinese medicine methods also have some unique therapeutic effects, such as massage, acupuncture, Fuchun San and Juxue Glucoside, which have the effects of “relaxing tendons and activating blood circulation”, improving microcirculation and analgesia on burn scars.
