Extracorporeal Shock Wave Therapy (ESWT) is a non-invasive procedure for the treatment of acute and chronic pain of the musculoskeletal system. Acoustic shock waves are characterized by a pressure surge with an extremely short rise time, which is then followed by an exponential drop in pressure and a brief phase of negative pressure. The shock waves used in ESWT focus or develop in the target tissue at the point where the pain is originating from. They cause an improved local blood circulation and metabolism. The primary means by which extracorporeal shock waves affect living tissue is based on the transformation of mechanical stimuli into biochemical or biomolecularsignals.The science behind ESWT is analogous to that of lithotripsy, a technology that makes use of acoustic shockwaves to break up kidney stones without surgery. The technique of using shockwaves to break up kidney stones has been around for nearly a quarter of a century. In the process of treating hundreds of thousands of patients, specialized machines were developed specifically with the idea of using the generated shockwaves in other parts of the body, e.g. to treat musculoskeletal conditions
