Effect of GaAs laser in patients with lateral epicondylitis triggered by DORT

Abstract

Objective: To assess the effects of low intensity laser therapy (LLLT) on pain and functionality of the elbow. Methods: The intentional sample consisted of 12 people randomly divided into two groups, as follow: six people in the intervention group (IG), who received the application of LLLT of 904 nm, and six in the placebo group (PG), who received the application of LLLT of 904 nm with the pen tip off. Seven applications by the method of sweeps were conducted in a 24-hour interval, using a dosage of 3 J / cm² with a duration of 12 minutes and 30 seconds. Results: There was a reduction of pain for the IG (P = 0.020) compared to the PG (P=0.889); and the functionality of the elbow increased for the IG (P=0.002) but worsened for the PG (P=0.363). Conclusion: It can be inferred from the data that the effects of low level laser therapy are effective in the treatment of lateral epicondylitis triggered by MSDs.
