[Eccentric exercises in the treatment of overuse injuries of the musculoskeletal system].

Overuse injuries of the musculoskeletal system are a common problem in both general population and among athletes. Researches made in the last decade have shown that overuse injuries are mainly caused by degenerative changes and not inflammation, as was thought before. Although they can be present everywhere in musculoskeletal system, overuse injuries are most often seen on tendons. The main goal of this article is to refer to latest guidelines in the treatment of overuse injuries, with special attention to eccentric exercise treatment program for most common tendinopathies (patellar tendinopathy, Achilles tendinopathy and lateral epicondylitis). The main reason is the fact that very good results are accomplished after eccentric exercises in the treatment of tendinopathies and are thus suggested as the first treatment option.
