Comparison of the effects of using non-steroidal anti-inflammatory drugs with or without kinesio taping on the radial nerve in lateral epicondylitis: A randomized-single blind study

•NSAID therapy plus KT improve pain intensity, functional status up to fourteen weeks.•KT also improve ultrasonographic findings, such as CET thickness and radial nerve swelling.•This is the first study to show the effect of KT on CET thickness and radial nerve using US in patients with LET. There is no knowledge about the effects of kinesio taping (KT) on the radial nerve in lateral epicondylitis. This study aimed to determine the effects of non-steroidal-anti-inflammatory drugs (NSAIDs) combined with KT on lateral epicondylitis using ultrasonographic findings. NSAID therapy was administered to the control group for 10 days, and the KT group additionally received KT three times a week for two weeks. Clinical and ultrasonographic evaluations were performed before treatment and at post-treatment at second, sixth and fourteenth weeks. The radial nerve cross sectional area and common extensor tendon thicknesses were measured using ultrasonography. The study was completed with 40 patients in each group. Improvements in clinical parameters, common extensor tendon thickness, and cross sectional area values were significant in the KT group (p
