Advanced controlled exercise protocols for tendon rehabilitation use biomechanical principles to promote organized collagen deposition while preventing re-injury during healing.
Controlled tendon rehabilitation welfare is shaped by understanding that the healing tendon requires mechanical stimulus — in the form of controlled walking — to organize collagen into functional parallel fiber alignment. Complete stall rest produces a healed but poorly organized tendon that fails at lower loads. The welfare tension is between insufficient loading (organized scar formation fails) and excessive loading (reinjury). Serial ultrasonographic monitoring resolves this tension by providing objective evidence of healing progress that guides exercise progression decisions. Horses that complete structured rehabilitation programs have better long-term welfare outcomes than those returned to work by time rather than healing assessment.
