What are the functions of shock wave therapeutic instrument?

Shock wave was first used in extracorporeal shock wave lithotripsy in clinical medicine. At the end of 1980s, extracorporeal shock wave lithotripsy (ESWL) technology began to be used in orthopedics and rehabilitation physiotherapy. After more than ten years of clinical research, shock wave therapy is becoming more and more perfect and its application scope is expanding. As a new treatment method between conservative therapy and surgical therapy, shock wave is popular in Europe and America.

The shock wave generated by the equipment is coupled into the human body through a water bag or other means, and the treatment is realized by focusing the focus.

Stress: Shock wave has certain acoustic characteristics in the propagation process, which will produce tension and pressure at different acoustic impedance interfaces, causing mechanical damage to materials, helping to loosen tissue adhesion and crush bone spurs.

Cavitation effect: when the shock wave propagates in the medium, it will produce a series of cavitation bubbles, which will grow, oscillate and burst in the process, releasing a lot of energy.

Analgesic effect: substance P is activated, and after a period of continuous action, the pain threshold increases and substance P production decreases.

Metabolic activation: shock wave changes the permeability of cell membrane, accelerates the ion exchange process inside and outside the membrane, and accelerates the removal and absorption of metabolic decomposition products.

Other functions: osteogenesis, production of vascular growth factor, etc.

Indications: Bone tissue diseases: delayed union and nonunion of fractures, early adult femoral head necrosis;

Chronic soft tissue injury diseases: tendinitis of long head of biceps brachii, calcified supraspinatus tendinitis, lateral epicondylitis of humerus, medial epicondylitis of humerus, plantar fasciitis, achilles tendinitis, etc. Relative indications: osteoarthritis, talus osteochondral injury, tenosynovitis, subacromial bursitis, patellar bursitis, patellar tendonitis, femoral trochanteric bursitis, elastic hip joint and muscle spasm, osteonecrosis diseases (lunate osteonecrosis, talus osteonecrosis, scaphoid osteonecrosis), etc.
