Comparing the Efficacy of Continuous and Pulsed Ultrasound Treatments in Lateral Epicondylitis

Lateral Epicondylitis Clinical Trial

Official title: Comparing the Efficacy of Continuous and Pulsed Ultrasound Treatments in Patients With Lateral Epicondylitis : a Double Blind, Randomized and Placebo-controlled Study

Status Completed

Clinical Trial Summary

Objectives: The purpose of this study was to investigate the efficacy of continuous and pulsed ultrasound treatments in lateral epicondylitis and to compare the efficacy of these two treatments against each other and placebo.

Patients and Methods: Fifty one patients diagnosed with lateral epicondylitis were included to the study. Patients were randomised to continuous ultrasound, pulsed ultrasound and placebo groups by using closed envelop method. First group received continuous ultrasound treatment. Second group received pulsed ultrasound treatment in proportion as. Third group received of placebo treatment. Resting and moving pain levels of the patients were evaluated by using visual analog scale. Muscle strength was evaluated by using dynamometer. For functional evaluation Duruoz's hand index and Patient-Rated Tennis Elbow Evaluation (PRTEE) scales were used. Evaluations were made at baseline, at the end of the therapy, and one month after the therapy. In addition, at baseline and at the end of the therapy, the thickness of the common extensor tendon was measured by using ultrasonic imaging (USG).

Clinical Trial Description

The purpose of this study was to investigate the efficacy of continuous and pulsed ultrasound treatments in lateral epicondylitis and to compare the efficacy of these two treatments against each other and placebo.

Fifty one patients (33 women, 18 men) diagnosed with lateral epicondylitis were included to the study. Patients were randomised to continuous ultrasound (n=17), pulsed ultrasound (n=17) and placebo (n=17) groups by using closed envelop method. First group received 10 sessions of 1 W/cm2 and 1,5 MHz continuous ultrasound treatment. Second group received 10 sessions of 1 W/cm2 and 1,5 MHz pulsed ultrasound treatment in proportion as 1:4. Third group received 10 sessions of placebo treatment with the same device seemed to be working but without delivering any output. Resting and moving pain levels of the patients were evaluated by using visual analog scale. Muscle strength was evaluated by using dynamometer. For functional evaluation Duruoz's hand index and Patient-Rated Tennis Elbow Evaluation (PRTEE) scales were used. Evaluations were made at baseline, at the end of the therapy, and one month after the therapy. In addition, at baseline and at the end of the therapy, the thickness of the common extensor tendon was measured by using ultrasonic imaging (USG). ;
