What Is a Low-Level Laser?
Unlike high power lasers that use heat and destroy tissue, low energy lasers affect the cellular energy of the underlying tissue. Hot lasers have a thermal effect and have an output of 1MV or above. Cold (or) Low Level Lasers do not have a thermal effect on tissue, lasers that stimulate biological function have an output below 10MV -milliwatts (ten-one thousands of a watt).
What is Low Level-Laser Therapy?
Low Level Laser Therapy refers to the modality of applying a “low” energy or “low level” laser to tissue that stimulates cellular processes and thereby enhancing biochemical reactions. For example, studies show that LLLT increases ATP production in the mitochondria of the cell. Since more energy is now available, the cell may utilize this fuel to function or operate more efficiently. LLLT has been used to treat athletes in the Tour de France as well as the NFL.
What Conditions Can Be Treated with Low-Level Lasers?
Low Level Laser Therapy has been successfully used to treat many conditions such as acute and chronic pain reduction, repetitive use disorders like carpal tunnel syndrome, soft tissue strains and sprains, inflammation reduction, enhanced tissue wound healing and cell regeneration.
What Makes One Laser Different from Another?
A laser can differ in its wavelength, power source or whether it is a continuous, pulsed or wave form. The first lasers were used to cut, cauterize or ablate tissue and were classified as “hot” lasers. “Cold”, “Low Energy” or “Low Level” lasers are used to enhance the metabolic activity at the cellular level through non-thermal reactions. We have both hot (Class IV) and cold (Class III) lasers at Utah Sports and Wellness.
