da Luz DC, et al. - Through a randomized, double-blind clinical trial of 24 patients with lateral epicondylitis (LE), researchers assessed the impacts of iontophoresis in patients with LE. Both groups revealed a notable improvement in pain on exertion and rest, improved handgrip strength in elbow extension and flexion, and improved function, as assessed by the Patient-Rated Tennis Elbow Evaluation scale. Iontophoresis exhibited superior outcomes in comparison with the galvanic current in pain on exertion and rest and in the function of people with tennis elbow. Therefore, iontophoresis concluded to be an efficient technique in decreasing pain and improving strength and function in people with LE (tennis elbow).
