Extracorporeal shock wave therapy has not been used to treat musculoskeletal diseases for a long time, but it is a safe, effective, non-invasive, and low-complication treatment method. A series of studies on various diseases have shown its good application prospects.

Pneumatic Shockwave Machine for the treatment of musculoskeletal system diseases was not reported individually in the late 1980s, and was not widely developed in Europe until the late 1990s. The application and basic research of shock wave therapy in the field of orthopedics are increasing, the indications are also expanding, and special shock wave equipment for orthopedics has also been developed. Physical Therapy Apparatus supplier believes that although extracorporeal shock wave therapy is not used for the treatment of diseases of the musculoskeletal system for a long time, it is a safe, effective, non-invasive, and low-complication treatment method. A series of studies carried out by the disease have demonstrated its good application prospects.

1. Definition of shockwave

Shock wave is a kind of mechanical wave, it has some properties of acoustic, optical and mechanical, shock wave can be seen everywhere in life in general, such as vibration, thunder and lightning, explosion and supersonic aircraft can produce shock wave, the shock waves have higher pressure instantly and the characteristics of high-speed transmission, only in the energy, frequency, and the way of produce is different, etc.

2. Discovery of shockwave and its medical application history

Early '60 s, west Germany (the federal republic of Germany), Neil airlines technology researchers found that when the plane high-speed through the rain, can produce a shock wave can make the plane within the device is damaged, and the aircraft's shell is in good condition, this phenomenon has attracted the attention of a great physicist, in 1963 the company set up a shockwave laboratory.In 1966, an engineer at the laboratory came into contact with a working shockwave target. His body felt like an electric shock, and the learned engineer immediately realized that this was the effect of the shockwave entering the body.Aisen pogue, a professor at Munich university institute of surgery, and Neil street, shock wave effect laboratory personnel to work together, finally in 1972 proved that the shock wave transmission through water can crush in vitro kidney stones, this success is the first milestone in the history of extracorporeal shock wave lithotripsy, it opened up a new era of urinary stones treatment.To 1980 west Germany Munich Ludwig Maximilian university department of urology jose will be used for the first time in the clinical treatment of kidney stones patients.In 1985, China successfully developed the first stone crusher.

3. How it works

The shock wave is generated by a variety of principles such as electro-hydraulic shock wave, piezoelectric effect, shaped laser, electromagnetic induction and micro-explosion.(1) the source of the electro-hydraulic shock wave was first invented by dunil company in Germany and applied to the source of the shock wave.Advantages: steady pulse waveform, fast impact time.Faults;Treating a patient requires changing the electrodes, poor discharge stability, and a shift in focus.(2) source of electromagnetic shock wave;Advantages;Low noise, no need to replace the electrode, stable discharge.Disadvantages: the shockwave time is slow, the clinical effect of using high energy voltage at 13~20kv is worse than that of the electro-hydraulic shockwave.The shockwave generator was developed in collaboration with Siemens ag and metz university.(3) piezoelectric crystal impact wave source;Pros: minimal noise.Disadvantages: small power, high quality and life of the crystal and installation requirements, or the trigger pulse of each crystal is difficult to synchronize.(4) pneumatic ballistic impact wave source;Advantages: good effect on muscle tissue.Disadvantages: it is not possible to treat polyps, strictures and other pathologies formed by staying in one place for a long time at the same time.

4. Clinical application and advantages

Portable Shockwave Therapy is a therapy for pathological reversal of tissue diseases such as muscles, bones, internal organs of the human body. The main applications in medicine are: tumor and cancer cell shock therapy in the whole body system; skeletal system Periarthritis of shoulder, tennis elbow, patella tendinitis, heel pain, etc .; extracorporeal shock wave lithotripsy treatment of urinary system, etc.

The advantages of extracorporeal shock waves are: (1) minor damage, which can replace certain surgical treatments; (2) generally simple anesthesia or no anesthesia; (3) short treatment time, low risk, can be treated in the outpatient clinic; (4) No special postoperative treatment is required, and the postoperative recovery is faster; (5) The cost of treatment is much lower than that of open surgery.

5. Indications

1. A variety of orthopedic diseases: pain caused by acute and chronic traumatic diseases, periarthritis, acromial bursitis, biceps long tendonitis, calcified supine tendonitis; tennis elbow (external epicondyle of humerus Inflammation), medial epicondylitis of the humerus; chronic traumatic diseases of the hips and knees, such as snapping hips, jumping knees (tibial tuberosity epiphyseal osteochondritis), knee arthritis; heel diseases: heel pain and Bottom fasciitis, etc .; lumbar muscle strain, acute and chronic lumbar soft tissue injury.

2. Delayed fracture healing and nonunion

3. Avascular necrosis of the femoral head

4. Joint stiffness after surgery or soft tissue adhesion contracture
