This prospective comparative study aimed to evaluate the efficacy of physiotherapy interventions in patients with lateral epicondylitis. The study included two groups, Group A and Group B, and was conducted at tertiary hospitals. Group A received conventional treatment consisting of pulsed ultrasonic therapy and exercise therapy, while Group B received a different intervention. The Patient-Rated Tennis Elbow Evaluation (PRTEE) scores were assessed pre and post-intervention in both groups. The results demonstrated that both interventions led to significant improvements in PRTEE scores, indicating a reduction in pain and functional limitations. However, there was no significant difference in the post-scores between the two groups, suggesting that both interventions were similarly effective. These findings highlight the potential benefits of physiotherapy interventions in managing lateral epicondylitis.
