What is now euphemistically called acoustic wave therapy (AWT) goes by several other names: pressure wave therapy, extracorporeal shockwave therapy (ESWT, the correct name and the original one coined by scientists), shockwave therapy (the shortened version of the correct name) and lipotripsy (the most ridiculous one I have seen). Before shockwaves were used for (questionable) cellulite removal, they were initially used to break down kidney and gallbladder stones, hence the medical name lithotripsy, meaning breaking down stones. From that, one crafty marketer coined the term “lipotripsy”, i.e. breaking down fat, although shockwaves do NOT physically break down fat.
