Low-Intensity Laser
Therapy
LILT, What is it?
Find Out Exactly What Is LILT.
LILT is the abbreviation for low-intensity laser therapy or low level laser light therapy. LILT or low-intensity laser therapy is sometimes called cold laser therapy. It is called low-intensity laser therapy because most laser use associated with medicine is to cut or burn tissue. LILT operates under and entirely different principal. LILT uses the concentrated light from a laser to stimulate healing instead of cutting or burning. LILT laser therapy avoids damaging tissues by producing a laser beam under power that is too low to elevate the temperature of the tissues treated by high enough to deliver photons of light below the surface of the skin.

LILT laser therapy as a concept for use in healing was first discovered by European Scientist Endre Mester. Dr. Mester was involved in research designed to prove that lasers caused cancer. To prove his point he shaved a group of mice, divided the group in two and applied LILT laser therapy to one group and regular light to the other. Neither group exhibited cancer symptoms. The interesting part was that the hair grew back much faster in the group treated with LILT than the group not treated with LILT. From that day forward, research has been conducted to determine how Mester’s discovery could be used in healing.

LILT—There are Many Different Devices, Are they all the Same?
Since Dr. Mester’s discovery and the subsequent evidence that
low-intensity laser therapy (LILT) is a useful treatment for
certain kinds of injuries and painful conditions. There has been a great deal
of research and experimentation regarding which device, wavelength or power is
most effective. In considering LILT (low-intensity laser therapy) it is most
important to understand the wavelength of the device you are being treated
with. LILT wavelength treatments can be anywhere from 500nm to 1,000nm.
Research has shown the most effect LILT wavelength to be in the range of 800nm
to 870nm with the specific LILT wavelength 830nm being best. The 830nm
wavelength delivered at 30 mW of power is capable of penetrating up to two
inches beneath the skin surface. See diagram below.
The low intensity laser (LILT) sends photons (light) into the injured
tissues and can penetrate two to three inches to treat affected areas. It uses
a natural enhancement of the cellular machinery that can and has been
dynamically measured in published studies to promote healing without burning
affected tissue. Once the photons find the injured tissues, they stimulate and
energize the cells to repair and strengthen at a remarkable rate. The treatment
does not hurt, takes about 30 minutes and is very cost advantageous. The
therapy is so effective that professional sports franchises and practioners
alike that treat chronic injuries are using low intensity lasers with vast
improvement of conditions such as carpal tunnel syndrome, fibromyalgia, back
pain, neck pain, excessive adhesions and scar tissue formation,
peyronie’s disease, multiple sclerosis, joint sprains, tendon strains,
epicondylitis and bursitis.
