Extracorporeal shockwave therapy is a commonly used method to treat pain and inflammation in horses. High energy acoustic waves are introduced to the tissues at varying frequencies to stimulate cell growth, reduce nerve pain transmission, and increase swelling drainage. This method is used commonly for soft tissue injuries, back pain, foot pain, and bony lesions. There are two types of shockwave therapy used. 1) Radial shockwave is used for superficial injuries 2) Focused shockwave is used for deeper tissues with a focusing array set to a specific depth.
