How Cold Lasers and Low-Level Lasers Work to Relieve Pain

Throughout the years, cold or low-level laser therapy (LLLT) has become a hot topic in the medical community. As more research on cold laser technology is conducted, organizations and agencies across the world are beginning to recognize the many benefits that LLLT can offer patients.

Erchonia’s commitment to scientific and clinical research in the advancement of LLLT has made the company a recognized world leader in LLLT technology. The following is an explanation of Erchonia’s cold low-level lasers and their benefits in the medical community.

What is Cold Laser Treatment?

LLLT, also called cold laser therapy or photobiomodulation therapy, is a type of phototherapy designed to repair tissue, reduce pain and inflammation, target fat and provide other benefits for patients in both medical and veterinary treatments. The capabilities of low-level lasers have been used in fat loss and pain relief for over 50 years.

During a treatment regimen, a small device emitting laser beam or visible nonthermal lasers is placed over the target area. The low levels of light penetrate the tissue without heating or damaging the skin.

Unlike traditional lasers, which use around 300 watts, cold lasers use between five and 500 milliwatts. True to their name, they don’t burn the skin or produce pain, and the FDA gives them NHN (non-heating instruments) classification. In contrast, a laser used for surgeries cuts through the skin and can lead to severe scarring and pain.

How Low-Level Lasers can be Used for Pain Relief

Cold lasers can stimulate all types of cells, including muscle, ligaments, nerves and cartilage. This stimulation of light energy works similar to photosynthesis in plants, as it is absorbed and interacts with light-sensitive components in the body’s cells. The treatment promotes the body’s natural healing — which may have been impeded through the tissue damage — by stimulating mitochondria and encouraging the cells to produce more ATP.

As a non-invasive procedure, LLLT can be performed at an outpatient clinic, providing a distinct advantage over traditional laser surgery. There is no recovery time and no side effects, which makes LLLT an attractive treatment option for a variety of conditions, including:

  • Relieves acute and chronic pain
  • Increases the speed, quality and tensile strength of tissue repair
  • Increases blood supply
  • Stimulates the immune system
  • Stimulates nerve function
  • Develops collagen and muscle tissue
  • Helps generate new and healthy cells and tissue
  • Promotes faster wound healing and clot formation
  • Reduces inflammation
