Osteopathy for Arthritic Equine Athletes

Click to view

Arthritis is one of the most common and consequential conditions affecting performance horses. As cartilage deteriorates, joints become painful and restricted — triggering a cascade of compensatory changes throughout the body that can ultimately be more damaging than the arthritis itself. In this clinically focused thesis, Charlotte Sweeney explores how equine osteopathy offers a powerful tool for managing this complex condition, not by reversing arthritic change, but by addressing its systemic consequences. Sweeney begins with a clear, accessible explanation of osteoarthritis — its mechanisms, its triggers, and how it progresses within synovial joints under the demands of competition. She then traces how the equine body compensates for an arthritic joint: surrounding muscles tighten and shorten, loading shifts to neighbouring structures, and a domino effect of somatic dysfunction spreads across the musculoskeletal system, creating referred pain, postural collapse, and eventually, secondary injuries. At the heart of the thesis is an exploration of how Osteopathic Articular Balancing (OAB) directly addresses these compensatory patterns. By mobilising restricted joints, elongating contracted soft tissues, and enhancing circulation and lymphatic drainage, OAB can reduce inflammation, restore range of motion, and interrupt the pain cycle — all without the risks associated with pharmaceutical intervention or high-velocity manipulation. A detailed case study of a 14-year-old Thoroughbred eventer with bilateral tarsal arthritic change brings the theory to life, documenting how targeted osteopathic treatment over four sessions produced measurable improvements in stride length, comfort, and soft tissue release. The thesis concludes with practical guidance on veterinary collaboration, contraindications, and the responsible use of HVLA techniques in arthritic patients. Essential reading for equine therapists and horse owners alike.
