How are Shockwaves Generated

There are four primary methods for generating shockwaves, which, without delving into the technical details, include spark discharge, piezoelectric, electromagnetic, and pneumatic (also known as electrohydraulic). Each method produces shockwaves with varying energy levels and penetration depths in human tissue.


In therapeutic applications, the pneumatic system is the most widely used because it generates a radial (dispersive) pressure wave. While radial waves are typically produced using the pneumatic/ballistic technique, some modern electromagnetic devices also incorporate this approach.


Shockwave therapy types

Focussed shockwaves are primarily used in surgical procedures due to their intense and precise nature. However, because of their potential for tissue damage, they have traditionally been considered less suitable for therapeutic treatments—though this perspective is evolving. Focussed waves are sometimes called "hard" shockwaves, whereas radial waves are often referred to as "soft" shockwaves, adding another layer of complexity to the terminology.
