Extracorporeal shock wave therapy (ESWT) is a Non-invasive Therapy in which acoustic waves carry high energy to painful areas and myoskeletal tissues with subacute, acute, or chronic conditions. The energy promotes regeneration and reparative processes of bone, tendons and other soft tissue.
Extracorporeal shock wave therapy, or ESWT, has emerged as a possible treatment option for patients with chronic tendon problems. ESWT delivers focused shock waves to the body, and has been used for treatment of a variety of conditions including:
There is both a high-energy and low-energy form of shock wave treatment, and both forms of therapy can be used in the treatment of these conditions.
Low-energy shock wave treatments are given as a series of three or more treatments. The low-energy shock waves are not painful, or mildly painful. On the other hand, the high-energy shock wave treatments are given at one session. High-energy shock wave treatments are quite painful, and often some type of anesthesia is needed. Either a regional block or general anesthesia can be administered for the high-energy treatments.
Shock wave therapy is thought to work by inducing microtrauma to the tissue that is affected by these problems. This microtrauma initiates a healing response by the body. The healing response causes blood vessel formation and increased delivery of nutrients to the affected area. The microtrauma is thought to stimulate a repair process and relieve the symptoms of pain.
