OBJECTIVES: The aim of this study was to evaluate and compare the effects of radial extracorporeal shock wave therapy (rESWT) and supervised exercises with neuromuscular inhibition (NMI) technique in improving pain, function, and grip strength in the treatment of patients with lateral epicondylitis (LE). PATIENTS AND METHODS: A total of 50 patients with LE (11 males, 30 females; median age 46 years; range 23 to 57 years) whose symptoms persisted for at least three months between February 2015 and August 2015 were included in the prospective, randomized-controlled, clinical study. The patients were divided into two groups as the rESWT group (n = 25) receiving a total of three rESWT sessions (once per week with 1.8 bar pneumatic pressure, 10 Hz frequency, and with 2,000 pulses) and the exercise group (n = 25) receiving supervised exercises with NMI (three times per week for three weeks). Pain and function were evaluated using visual analog scale, the total Patient-Rated Tennis Elbow Evaluation, the Roles and Maudsley score, while the grip strength was evaluated using a hand dynamometer at one and three months after treatment compared to baseline. RESULTS: A significant improvement was observed in all outcome criteria at one and three months after treatment, compared to baseline, in both the rESWT and exercise groups (p < 0.05). There was no significant difference in terms of the changes in the outcome criteria between the groups (p > 0.05). CONCLUSION: The rESWT seems to provide no significantly superior benefit than supervised exercises with NMI at least until the three months in the treatment of LE.
