No consensus has yet been built on the treatment of lateral epicondylitis (LE) due to the lack of evidence. Although conflicting results are present, radial extracorporeal shock wave therapy (rESWT) has increasingly been used in the treatment of tendinopathy

ESWT and exercise have beneficial effects on the management of tendinopathies owing to their various mechanisms that showed therapeutic efficacy. Owing to its positive outcomes, extracorporeal shock wave therapy (ESWT) has recently been used in the treatment of musculoskeletal system diseases such as plantar fasciitis, Achilles tendinopathy, calcific rotator cuff tendinopathies, and patellar tendinopathy
