Navicular Syndrome and shock wave therapy

In 2004, Scott McClure, DVM, PhD, DACVS, at Iowa State University, presented an evaluation of 32 horses treated with shock wave for navicular syndrome.¹

  • 2,000 shocks at Energy level E6
  • Dr. McClure recommended approaching through the heel bulbs and the frog and most importantly, soaking the foot the evening before the treatment to ensure transmission of sound energy through the heel.
  • 6 months post-treatment 27 horses were available for evaluation
  • 70% of the cases showed improvement at a trot
  • 81% of horse owners reported improvement
  • Lameness in the horses that responded did not relapse in the 12-month period following treatment and no complications reported.
