Use of light in the treatment of physical or mental illness is called photo therapy. Phototherapy is currently used to treat a variety of musculoskeletal conditions. Recent meta-analyses performed and provided evidence for the clinical usage of phototherapy for pain and tissue repair. Phototherapy has also been shown to decrease the onset of delayed onset of muscle soreness after exercise. The attenuation of muscle fatigue with phototherapy is a new topic in the field of physical therapy. The application of red and infrared diodes with a dosage 25.1 joules over three areas on the quadriceps resulted in higher torque produced by the knee extensors following 30 maximal concentric knee extension and flexion contractions as compared to a placebo treatment. However, performance in the lower body Wingate test was not enhanced following phototherapy application.
