What Is Low-Level Laser Therapy?
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. Furthermore, it emits no heat, sound, or vibration.
Basically, specific wavelengths of light to interact with tissues to help accelerate the healing process. This modality can be used on a variety of acute and chronic conditions in order to help eliminate pain, swelling, reduce spasms, and increase functionality. LLLT is used by some Chiropractors and Physiotherapists (including those right here at MYo Lab!) to treat various musculoskeletal conditions.
How Does LLLT Work?
LLLT is believed to affect the function of connective tissue cells (fibroblasts), accelerate connective tissue repair and act 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 a targeted area. The body tissue then absorbs the light.
The red and near-infrared light cause a reaction, and the damaged cells respond with a physiological reaction that promotes regeneration. Although you’ll feel the laser device touching your skin, the procedure is painless and noninvasive. As mentioned above, there will be no sound and you’ll feel no vibration or heat. Each treatment typically takes only a few minutes.
