Have you heard about the latest advance in pain relief? It is called Class IV high power cold laser
therapy. Let’s take a look at the
history of light therapy, what laser therapy is, what physiologic changes
occur, what conditions benefit from its use and its safety and effectiveness.
Laser is an acronym.
It stands for Light Amplified by Stimulated Light Emission of
Radiation. It was theorized by Albert
Einstein in 1916, invented by Theodore Maiman in 1960. In 1967 Endre Mester discovered the bio stimulatory
properties of laser light.
Therapeutic lasers are used for the stimulation of cell
function. Their biological effect is
photo chemical not thermal, as is the case with surgical lasers. A class IV laser delivers therapeutic doses
of light to large areas in a short period of time. These wave lengths of light that are used are
not new. Initially, bulbs producing the
therapeutic wave lengths were used, but they were of lower power, about 5
milliwatts, and treatment times were measured in hours. High power lasers have up to 15 watts of
power and treatment times are measured in minutes.
What does laser light therapy do to your body? Research
shows it speeds healing by 300 to 1000 percent!
How? It increases cellular
metabolism by increasing ATP production (ATP is energy for the cells), it
increases the reproduction of cells that build immunity, and it reduces
inflammation of injured tissues and bruising.
Laser increases the release of endorphins, our natural pain killers; and
it suppresses PGE2 production by damaged tissue, which causes pain. In plain English, it kills pain, reduces
swelling, increases blood supply and speeds healing of open skin wounds and
deep tissue injuries.
The target of laser treatment is not a particular disease,
but it is to stimulate the appropriate cells that spur on the body’s natural
repair mechanisms. Increasing oxygen to
cells is the name of the game.
There are more than 2500 studies worldwide and over 100
double blind studies showing effectiveness for many conditions. There is a very clear picture in research of
where light is absorbed in cells and which processes these interactions
catalyze (help along.)
So how can you benefit?
The conditions that respond to laser therapy are vast. The list includes chronic neck and back pain,
carpal tunnel syndrome, repetitive stress injuries, plantar fasciitis, disc
herniation, strains/sprains, muscle spasms, any tendonitis or bursitis,
osteoarthritis, TMJ pain, tennis elbow, open wounds and many more conditions. I have used the laser on each of the
conditions listed with very good results in most cases. Does it cure everything? Nope, but it sure speeds healing along with
proper overall care.
