Low-Level Laser Therapy (LLLT) (also known as Cold Laser Therapy) is a low-intensity laser therapy that stimulates healing while using low levels of light. The technique is consequently called “cold” laser therapy because the low levels of light aren’t enough to heat your body’s tissue. The level of light is a non-invasive light source treatment that generates a single wavelength of light that emits no heat, sound, or vibration.
At MYo Lab, our Chiropractors and Physiotherapists are trained to use LLLT to treat various musculoskeletal conditions to help you manage pain, promote healing, and improve mobility.
Basically, specific wavelengths of light interact with tissues to help accelerate the healing process. This modality can be used on a variety of acute and chronic conditions to help eliminate pain and swelling, reduce spasms, and increase functionality.
How Does LLLT Actually Work?
LLLT affects the function of connective tissue cells (fibroblasts), accelerates connective tissue repair and acts as an anti-inflammatory agent. Lasers with different wavelengths, varying from 632 to 904 nm, are used. During this procedure, different wavelengths and outputs of low-level light are applied directly to the targeted area. The body tissue then absorbs the light.
The red and near-infrared light causes a reaction, and the damaged cells respond with a physiological reaction that promotes regeneration and enhances circulation/blood flow. Although you’ll feel the laser device touching your skin, the procedure is painless and noninvasive. As mentioned above, there will be no sound associated with the therapeutic laser itself, and you’ll feel no vibration or heat. Each treatment typically lasts 5-15 minutes.
