Background of shock waves During World War II, people observed that the lung tissues of the torpedo victims were severely traumatized, but the torso was not damaged, thus discovering the special sound waves of shock waves. In the following decades, people began to study the phenomenon of shock waves systematically. It was found that shock waves in water could break plaster blocks. In 1983, the first extracorporeal shock wave lithotripter was introduced. At the end of 1980s, it was found that shock waves did not damage the hip bone tissue in the treatment of kidney stones, but they could induce osteoblastic potential from microhistology. Gradually, people transferred the special effect of shock wave, which can activate tissue regeneration, to the treatment of orthopedic system diseases. In the 1990s, shock wave non-invasive treatment of poorly healed fractures and femoral head necrosis began to emerge. Shockwave therapy began to branch out in the field of orthopedics. In recent years, good results have been received in the treatment of tendon-bone junction lesions, tendonitis and tendinopathies using shock waves of low to moderate energy. The introduction of a new type of electromagnetic low-energy shock wave therapy, specifically targeting the muscular soft tissue system, has brought new hope to the field of orthopedic sports medicine. The clinical application of low-energy shock wave Shock wave is a special kind of sound wave, by adding high pressure in a few nanoseconds to accelerate the wave, waveform changes, and then suddenly released to produce huge energy. It can produce cavitation effect on human tissues, i.e., it rapidly activates the tiny vacuoles in tissues, which gather and rupture in an instant and act on the adjacent tissues. It can promote tissue regeneration, capillary and epithelial cell renewal, and induce the expression of IGF-1 and TGF-β1 and other tissue growth factors to achieve the purpose of tissue wound repair. In the field of orthopedic sports medicine, shock wave therapy has been widely used in the treatment of tennis elbow, Achilles tendinitis, Achilles tendon terminal disease, patellar tip terminal disease, calcific tendinitis and other systemic tendon bone junction lesions and tendinopathies, which were once a headache and problem for orthopedic and sports trauma doctors. The principle and process of treatment is also different from traditional physical therapy and local sealing. The treatment method is no longer based on the traditional thermal and magnetic principles, and its good tissue penetration is the guarantee of its efficacy. Patients are non-invasive during the treatment process, no skin trauma, no worry about bleeding and infection, and no need to worry about the side effects of hormonal drugs. Treatment precautions: 1. Treatment cycle: generally 1 treatment per week, one week (7 days) as a cycle, a course of treatment generally 3-5 times, at least 3 times. It is recommended that you adjust your work and rest schedule during the treatment cycle and be able to adhere to it on time. 2.During the treatment process, due to the different amount of pain tolerance of each person, some patients may experience pain, our doctor will adjust the impact energy for you in time. Please inform your pain feeling correctly during the treatment. 3.You can move around and go to work on the same day after the treatment, there is no impact. However, during the treatment cycle, please try to reduce the muscle firing and activities at the treatment area. 4.For a few days after the treatment, you may feel redness, heat, swelling and discomfort at the impact site. This is because the local tissues are undergoing trauma repair, which is a normal phenomenon. It is recommended that you use ice packs locally for 1-2 days after treatment. The symptoms will basically disappear within a few days. 5, a course of treatment after the initial period, please try to reduce sports or local injury force, generally need to rest 1 ~ 2 weeks, using the treatment site fully healed. It is recommended that you wear a local protective gear, under the full protection of protective gear for activities. 6.After the treatment is completed, you are recommended to actively participate in our follow-up work and come to the clinic regularly for follow-up. We will guide you in the relevant rehabilitation treatment.
