What this Trial Is About
Researchers are evaluating the effects of two different dosages of high-intensity laser therapy on patients with lateral epicondylitis, also known as tennis elbow. This condition causes pain and affects quality of life. High-intensity laser therapy is a non-invasive treatment that can reduce pain, improve blood flow, and promote tissue repair by penetrating deeper into affected tissues. The study aims to understand how treatment dosage influences these benefits, as past research has shown varied dosage and frequency. Participants will be randomly assigned to one of three groups: a placebo group receiving sham high-intensity laser therapy combined with infrared ray and transcutaneous electrical nerve stimulator therapy; a low dosage group receiving low-dose high-intensity laser therapy with the same additional therapies; and a high dosage group receiving high-dose high-intensity laser therapy plus the additional therapies. Infrared ray and nerve stimulator therapies are applied for 15 minutes each on the affected area. Throughout the 4-week treatment period, researchers will assess pain intensity as the primary outcome. Secondary outcomes include grip strength and quality of life. Participants will undergo evaluations from enrollment until treatment completion to monitor changes. The study is double-blinded and randomized, ensuring careful monitoring of effects and safety during the process.
