In 1963, the company set up a shock wave research laboratory. In 1966, one of the engineers in the laboratory came into contact with a working shockwave target, and his body produced a sensation like an electric shock, which the engineer immediately realized was the effect of the shockwave entering the human body. Eisenberg (Professor at the Institute of Surgery, University of Munich), in collaboration with the laboratory staff, demonstrated in 1972 that shock waves propagated through water could crush isolated kidney stones, and in 1980, West German medical doctors used extracorporeal shock wave technology for the first time to treat kidney stone patients, which became a milestone in the application of shock wave medicine. Since then, extracorporeal lithotripsy has virtually replaced surgical procedures. In 1987, shock wave technology was used for the first time in orthopedic treatment. In the mid-1990s, about 100,000 to 150,000 orthopedic patients were treated with shockwave therapy in Germany each year, a number that far exceeded the use of shockwave lithotripsy in urology. Second, the treatment mechanism shock wave is a mechanical wave, it has acoustic, optical and mechanical properties of certain, broad shock waves in life can be seen everywhere, such as vibration, lightning, explosions and supersonic aircraft can produce shock waves, shock waves have instantaneous pressure increase and high-speed conduction characteristics, only in the energy, frequency and the way to generate differences. Treatment mechanism: 1, mechanical effects: shock waves in the process of propagation with certain acoustic properties, in different acoustic impedance interface will produce tension and pressure, mechanical damage to the material, help to loosen tissue adhesions and crush the tissue calcium salt deposits. 2, cavitation effect and thixotropic biological effect: shock wave propagation in the medium will produce a series of cavitation bubbles, these cavitation bubbles in the movement of growth, shock, collapse, release energy, improve tissue microcirculation and metabolism. 3.Analgesic effect: It can mask the transmission of pain signals by nociceptive nerves and activate the endogenous analgesic substances at the patient site to increase the pain threshold and relieve pain. 4.Metabolic activation: change the permeability of cell membrane, accelerate the ion exchange process inside and outside the membrane, and accelerate the removal of metabolic decomposition products. 5. Other effects: osteogenic effect, production of pro-vascular growth factor, etc. Third, in the application of physical therapy Shockwave therapy is a physical therapy, with physical properties similar to ultrasound therapy, due to its mechanical effect, cavitation effect and thixotropic biological effect is obvious, small doses have a catalytic effect, large doses are destructive effects, so it must be strictly clinical application range, reasonable choice of treatment parameters, according to the physical properties and anatomical structure of the correct operation to ensure efficacy. Certain difficult problems can be solved through rational use, but it is also necessary to cooperate with other rehabilitation treatments to eliminate the development of the disease. Advantages of the technique: minor injuries, alternative to some surgical treatments or acupuncture; no anesthesia required; short treatment time, low risk, can be performed on an outpatient basis; no special treatment required after treatment and faster recovery; treatment costs are much lower than surgery costs. Indications: Orthopedic and soft tissue diseases, including frozen shoulder, subacromial bursitis, biceps long head tendonitis, calcific supraspinatus tendonitis, tennis elbow (humeral epicondylitis), humeral medial epicondylitis, chronic injury diseases of hip and knee, such as popping hip, jumping knee (tibial tuberosity epiphyseal osteochondritis), etc., heel pain and plantar fasciitis, etc.; osteonecrosis diseases (lunar osteonecrosis, talar osteonecrosis, navicular Osteonecrosis), etc. Contraindications: 1. Systemic factors: patients with cardiac pacemakers, patients with bleeding disorders and tumors, patients with thrombosis, patients with immature bone pain, and pregnant patients. 2. Local factors: various infections and skin breakdown at the treatment site, acute tendon and fascia inflammation and joint effusion; shock wave focus should not be used on spinal cord tissue, large blood vessels and nerve travel areas, shock wave should not be used on bone infections and bone defects larger than 1 cm.
