In the field of diabetic foot ulcers a substantial amount of research is going on trying to develop existing methods of treatment and finding new therapeutic techniques. Extracorporeal shockwave therapy (ESWT) is a promising new option for ulcer treatment. ESWT has long been known in kidney stone treatment, and more recently ESWT has been established as treatment to regional pain disorders (such as plantar fasciitis of the heel and lateral epicondylitis of the elbow) and non-union of long bone fractures. Furthermore, ischemic heart disease and Peyronies disease have been treated with ESWT. Some studies show positive results when treating foot ulcers with ESWT.
