Extracorporeal shockwave therapy

Extracorporeal Shockwave Therapy (ESWT) is a non-invasive medical treatment that involves the use of sound waves to treat various musculoskeletal conditions. The term "extracorporeal" refers to the method of delivering the shock waves from outside the body.

History

The use of shockwave therapy in medicine began in the early 1980s, initially for the treatment of kidney stones (lithotripsy). Over time, the application of ESWT has expanded to include a variety of musculoskeletal conditions.

Mechanism of Action

The exact mechanism of action of ESWT is not fully understood. However, it is believed that the shockwaves cause microtrauma to the tissue, which stimulates the body's natural healing process. This includes the release of growth factors and the formation of new blood vessels (angiogenesis), which can help to repair damaged tissue.

Applications

ESWT is used to treat a variety of conditions, including plantar fasciitis, tennis elbow, Achilles tendinitis, and calcific tendinitis of the shoulder. It is also used in the treatment of certain types of erectile dysfunction.

Procedure

The procedure involves the application of a gel to the skin, which helps to transmit the shockwaves. A handheld device is then used to deliver the shockwaves to the targeted area. The procedure is typically performed in an outpatient setting and does not require anesthesia.

Efficacy and Safety

Numerous studies have demonstrated the efficacy of ESWT for various conditions. However, like all medical treatments, it is not effective for everyone and there can be side effects. Common side effects include pain or discomfort at the treatment site, swelling, and bruising.
