Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Patellar tendinopathy is one of the most common injuries in jumping athletes. Changes in mechanical and physiological properties of tendon are the two proposed forms of pathogenesis. The efficacy of eccentric exercise when applied alone and combined with extrocoporeal shockwave therapy had been reported; however, the underlying treatment mechanisms of pain and dysfunction are not clear. This project aimed to explore the mechanical, physiological and therapeutic effects of eccentric exercise when applied as a single treatment and as an adjunct to extracorporeal shockwave therapy.
