IntroductionLateral elbow tendinopathy (LET), commonly referred to as lateral epicondylitis, lateral epicondylalgia, lateral epicondylosis and/or tennis elbow is one of the most common lesions of the arm. However, LET is the most appropriate term to use in clinical practice because all the other terms make reference to inappropriate a etiological, anatomical and pathophysiological terms [1]. The condition is usually defined as a syndrome of pain in the area of the lateral epicondyle [2][3][4], that may be degenerative or failed healing tendon response rather than inflammatory [5]. Hence, the increased presence of fibroblasts, vascular hyperplasia, proteoglycans and glycosaminoglycans together with disorganized and immature collagen may all take place in the absence of inflammatory cells [5]. The origin of the extensor carpi radialis brevis (ECRB) is the most commonly affected structure [5]. It is generally a work-related or sport-related pain disorder. The dominant arm is commonly affected, the peak prevalence of LET is between 30 and 60 years of age [2,6] and the disorder appears to be of longer duration and severity in women [2,6,7] The main complaints of patients with LET are pain and decreased function [2,[8][9][10][11][12] both of which may affect daily activities. Diagnosis is simple, and a therapist should be able to reproduce this pain in at least one of three ways: (1) digital palpation on the facet of the lateral epicondyle, (2) resisted wrist extension and/or resisted middle-finger extension with the elbow in extension, and (3) by getting the patient to grip an object [1,[8][9][10].Although the signs and symptoms of LET are clear and its diagnosis is easy, to date, no ideal treatment has emerged. Many clinicians advocate a conservative approach as the treatment of choice for LET [2,[8][9][10][11]. Physiotherapy is a conservative treatment that is usually recommended for LET patients [11,13,14]. A wide array of physiotherapy treatments have been recommended for the management of LET [11,[15][16][17]. These treatments have different theoretical mechanisms of action, but all have the same aim, to reduce pain and improve function. Such a variety of treatment options suggests that the optimal treatment strategy is not known, and more research is needed to discover the most effective treatment in patients with LET [11,[18][19][20].Iontophoresis has attracted much interest in the last 20-25 years as it has been applied to common musculoskeletal conditions such as LET. Iontophoresis is a therapeutic technique that involves the introduction of ions into the body tissues by means of a direct electrical current [11]. Iontophoresis has several advantages as a treatment technique in than it is a painless, sterile, noninvasive technique for introducing ions into the tissue that has been demonstrated to have positive effect on the healing process [15]. Its effectiveness has been evaluated in two previously published sys...
