efficacy of dry needling in the treatment of lateral epicondylitis

Conditions: Tennis Elbow; Dry Needling

Summary: lateral epicondylitis is painful tendinosis of the main extensor tendon that occurs at the fibro-osseous junction of the outer elbow region. histopathological samples in patients with chronic lateral epicondylitis show that there is angiofibroblastic degeneration and failure in the normal tendon repair process rather than acute inflammation in this region. it has begun to be accepted that the main factor in lateral epicondylitis is not the inflammatory events but the degenerative process. there are many treatment methods that trigger structural healing in tendinopathies. in this study, the investigators aimed to evaluate the effect of the dry needling method of the lateral epicondyle region.

lateral epicondylitis occurs as a result of micro-tears and progressive degeneration caused by repetitive tension, especially at the attachment of the main extensor tendon to the lateral epicondyle. the treatment modality to be used, which causes an increase in functional cells, can prevent the apoptotic process; thus, it is suggested that there are methods that can reconstruct tendon structure and function. inflammation can have a positive effect on the healing process in the treatment of lateral epicondylitis. methods such as prolotherapy and platelet-rich plasma therapy are among the methods that trigger the inflammation process in the lateral epicondyle region and subsequently contribute to the regeneration process. in all these treatments, there is evidence that the local healing process is triggered by the 'needle effect'. dry needle therapy is a method that has been widely used in musculoskeletal diseases for many years, and it is one of the safe and cost-effective applications. in this study, the investigators planned to evaluate the clinical efficiency of dry needling of lateral epicondyle area those are the origin of the extensor muscle groups of the wrist in addition to the home exercise program and to compare the groups in terms of pain severity, functionality, and improvement in handgrip strength with the participants applied for the only home exercise program.
