Overview

High-intensity laser therapy has gained increasing attention in recent years as a therapeutic modality. It is a non-invasive treatment that can reduce pain, increase local blood circulation, and promote tissue repair. The higher energy output of high-intensity laser therapy also have deeper tissue penetration. Several studies have investigated the effects of high-intensity laser therapy on lateral epicondylitis, and the existing literature indicates that, compared with other treatment modalities, high-intensity laser therapy is more effective in improving pain and quality of life in patients with lateral epicondylitis.

However, the dosage, duration, and treatment frequency applied in previous studies vary considerably. The therapeutic effects of high-intensity laser therapy may therefore be influenced by treatment dosage. Consequently, the purpose of this study is to compare the effects of two different dosages of high-intensity laser therapy on patients with lateral epicondylitis.
