Tendinopathy is a failed healing response of the tendon. Despite an abundance of therapeutic options, very few randomized prospective, placebo-controlled trials have been carried out to assist physicians in choosing the best evidence-based management. Eccentric exercises have been proposed to promote collagen fiber cross-link formation within the tendon, thereby facilitating ...
