Low-Level Laser Therapy for Rheumatoid Arthritis: A Review of Experimental Approaches.

Introduction

Rheumatoid arthritis (RA) is an inflammatory and autoimmune disorder that is characterized by joint inflammation, pain, physical disability, and morning stiffness. In the present study, the effect of low-level laser therapy (LLLT) on RA was reviewed.

Methods

"Low-level laser therapy", "rheumatoid arthritis disease", and "photobiomodulation" keywords were searched in Google Scholar, PubMed, and Medline.

Results

A literature survey led to a discussion about the immunology of the RA, laser therapy, mechanism of LLLT action, and anti-inflammatory and immunomodulatory properties of LLLT.

Conclusion

It was concluded that LLLT could improve RA patients' quality of life, reduce pain, and enhance physical movement.
