Extracorporeal Shock Wave Therapy in Lateral Epicondylitis

Abstract

Tennis elbow, also known as Lateral Epicondylitis, is a condition caused by overuse of the muscle in forearm, particularly due to repetitive wrist and arm movements. This leads to inflammation of the tendons that attach to the lateral epicondyle of the humerus. The primary symptom experienced by patients is usually pain radiates from the lateral epicondyle toward the forearm. Currently, various treatments for lateral epicondylitis have been suggested, including physical therapy modalities (e.g. ultrasound, high power laser therapy), local injection with corticosteroid. Although corticosteroid injection can rapidly relieve pain. However, those treatment may not appropriate in some conditions and may cause side effects after long-term treatment. If the previously mentioned treatment are ineffective, Extracorporeal shock wave therapy (ESWT) has become an increasingly popular approach in modern physical therapy, as it is a non-invasive treatment, safe. The physiological mechanisms of ESWT emphasize on promoting healing process tissue. Moreover, it is a convenient treatment method. It has been recognized as effective in reducing pain and promoting tissue regeneration. Particularly in patients with chronic symptoms who do not respond to the conventional therapies. Several clinical studies and research evidence support that ESWT provides statistically significant therapeutic benefits in patients with chronic lateral epicondylitis. It has been shown to reduce pain and enhance the overall quality of life in affected individuals.
