Lateral elbow tendinopathy (LET) is a common condition in the upper limb, affecting up to 3% of the population annually. Eccentric strengthening has shown promise as a method to treat LET. Accordingly, the authors of this paper performed a meta-analysis to help determine whether eccentric strengthening is superior to other forms of strengthening and pain-relieving modalities for managing LET.

Lateral elbow tendinopathy affects up to 3% of the population annually.
