Wayne McIlwraith, BVSc, PhD, DSc, FRCVS, DrMedVet (hc), Dipl. ACVS, director of Colorado State University's Gail Holmes Equine Orthopaedic Research Center, at the 50th annual American Association of Equine Practitioners (AAEP) Convention in Denver, Colo., Dec. 4-8, 2004, involved ESWT's effects on osteoarthritis. In a model of induced osteoarthritis in horses, ESWT decreased lameness and synovitis, and it improved joint fluid and soft tissue quality. Anti-inflammatory activity continued for 42 days after the last treatment, when the study concluded.
