Shock Waves and Radial Pressure Waves: Time to Put a Clear Nomenclature into Practice

Abstract

Extracorporeal focused shock wave therapy and radial pressure wave therapy are noninvasive approaches with high success rates that hold promise for treating a rapidly increasing number of clinical indications. However, reports, presentations at scientific meetings, and information published by manufacturers reflect confusion in the terminology used. This situation is worrisome because both desired and undesired biological effects depend on the pressure profile and the physical parameters used. Moreover, in many cases, the detailed biological mechanisms involved are yet not fully understood. Only a clear knowledge of the physical concepts can enable comparison among and improvement of treatment protocols and technology. Fortunately, specific definitions and recommendations have been agreed upon by scientific societies promoting international standardization. The main goal of this article is to raise awareness of the importance of having a clear nomenclature worldwide and explain some of the concepts based on the international consensus that has been accepted to date.
