Low Level Light Therapy

Low level light therapy (LLLT) is the application of very low power red or near infrared light for promoting natural healing and pain relief. Though there have been many positive studies, LLLT technology remains controversial because its healing properties are not completely understood. In 2002, ML830 from Microlight Corporation of America became the first FDA approved laser in the U.S.

Who Can Benefit from LLLT?

• LLLT has provided pain relief for those suffering from nagging sports injuries or repetitive stress injuries (tennis elbow or carpal tunnel syndrome). LLLT has been useful to reduce lower back pain and migraines, specifically for people who take pain medication more than three times a week. Skin conditions such as acne, rosacea and scarring benefit from LLLT as well. According to a recent study by the University of Virginia Healthcare System, LLLT has the potential to improve neuronal cell function in those with Parkinson's disease.

How Does LLLT Work?

• LLLT is applied through a laser, directing biostimulative light energy into cells. The cells convert this energy to chemical energy, which can stimulate natural healing and relieve pain. LLLT consists of compressed light from the cold, red part of the electromagnetic spectrum. As a "cold laser", LLLT is generally considered non-thermal and safe as its radiation is kept at a very low level (below 100mW). Class IV lasers, LED devices, and other lasers with a power level above 100mW have had more instances of burning than LLLT.

Seeking Treatment

• Consult your doctor if you are interested in LLLT. She can direct you to the specialist you need for treatment. Keep in mind that LLLT is a relatively new technology and understanding of the implications of LLLT is incomplete.
