Eighty patients with lateral epicondylitis were randomized to receive either extracorporeal shockwave therapy (ESWT) (n=35) or a combination of ultrasonic therapy (US) and deep friction massage (n=39). The primary outcome of interest was pain reduction, measured using the Numeric Pain Rating Scale (NPRS), and functional improvement, assessed via the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire. Outcomes were evaluated at baseline, at the third week, and at the seventh week of treatment. Overall, the study revealed significant improvements in both groups, but ESWT demonstrated superior efficacy in reducing pain and improving functional outcomes. These findings suggest that ESWT is a more effective intervention for managing lateral epicondylitis compared to US with deep friction massage.
