Extracorporeal shockwave therapy

Synonym(s): ESWT, lithotripsy

Contributor(s): Ian Anderson, Scott McClure, Mark Revenaugh

Introduction

  • Extracorporeal shockwave therapy can stimulate bone, tendon and ligament healing.
  • High pressure waves stimulate cells by a yet undetermined mechanism or mechanisms.
  • A shockwave is an acoustic pressure wave that reaches up to 100 times atmospheric pressure in a few nanoseconds with a rapid decline.
  • Shockwaves can be reflected and focused.
  • Shockwaves can travel through soft tissue to the focal point   ESWT: shockwave at focal point - diagram  with no or minimal negative effects to the soft tissues.

Uses

Advantages

  • Non-invasive.
  • Minimal risk.

Disadvantages

  • Limited controlled data in horses at this time.
  • Large differences in shockwave generators and focusing mechanisms.
  • Excessive energy or pulse numbers can cause tissue damage.
  • Inadequate energy or pulse numbers are not therapeutic.
  • Should not be used near lung or gas filled cavities or open physes or sites of infection.
  • Large vessels and nerves should be avoided.
