What is 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 1MW or above.
Cold (or) Low Level Lasers do not have a thermal effect on
tissue, lasers that stimulate biological function have an
output below 10mw-milliwatts
(ten-one thousands of a watt).
Where is this
being
used?
The Erchonia cold laser device has gained recent FDA
approval for the non-surgical treatment of neck and
shoulder complaints and is being used widely in the NFL and
by the USPS tour de France team chiropractor.
The beneficial effects of the Erchonia laser are currently
being researched by leading plastic surgeons for use in
liposuction procedures.
How
does it work?
Many theories exist as to the mechanism of action for Low
Level Laser Therapy(3LT™) but simply put, photonic energy
is absorbed by the photo acceptor sites on the cell
membrane which trigger a secondary messenger to initiate a
cascade of intracellular signals that initiate, inhibit or
accelerate biological processes such as wound healing,
inflammation, or pain management.
When
the body has an injury the cells are damaged and fail to
function within normal parameters.
Low
level lasers penetrate deeply into the skin and work by
restoring this abnormal cellular function.
Physiologic effects include improved metabolism,
circulation and tissue healing.
Are there any side
effects?
There are over 1500 published studies and not one of them
mentions any negative side effects of semi-conductor diode
lasers at the 5mW range like the Erchonia 3LT™ Lasers.
Low Level Lasers are safe, non-toxic and non-invasive;
there has not been a recorded side effect in over 1700
publications.
There are some necessary common sense precautions that need
to be considered, such as avoiding pointing the laser beam
directly into the eye and maintaining it there, which could
prove to be damaging to the eye.
What makes one
laser different from another?
A laser can differ in its wavelength, power source or
whether it is a continuous or pulsed 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 metabolic activity
at the cellular level through non-thermal reactions.
What is wavelength?
And do the different wavelengths
matter?
Light is measured in wavelengths and is expressed in
units of nanometers
(nm). Different wavelengths have different energy levels
and can have various effects on tissue.
For example, the Erchonia 3LT™ Laser is 635 nanometers,
which is found within the "red" spectrum of visible light
(400-800 nm) and has anabolic tissue effects, whereas,
radiation that has a wavelength shorter than 320 nm
(ultraviolet (UV), gamma rays, x-rays) has ionizing effects
on cells and can be harmful even in small
doses.
How
long does the treatment last?
A
treatment plan may vary, depending on the condition. For
instance, an acute soft tissue injury or open wound may
require multiple short treatments initially then the
interval between treatments will lengthen as the
condition improves.
Laser
therapy may be useful in the following
conditions:
Ø
tendonitis
Ø
frozen
shoulder
Ø
fractures
Ø
post-operative
wounds
Ø
sprain-strains
Ø
scar
tissue
Ø
autoimmune
diseases
Ø
chronic
or acute pain
Ø
wound
healing
Ø
arthritis
Ø
migraines
Ø
disc
herniations
Ø
minor
nerve damage
Ø
carpal
tunnel syndrome
Ø
heavy
metal detoxification
Clinical
Uses of LLLT in Our Practice
Ø
Pain
Relief – by increasing levels of B-endorphins and reducing
the hyper-
irritability of nerve
cells.
Ø
Anti-Inflammatory
Effect – by decreasing the release of bradykinins,
histamines and
acetylcholine.
Ø
Muscle
Relaxation – by increasing ATP production.
Ø
Reduces
Swelling (Edema) – by increasing lymphatic flow.
Ø
Reducing
Trigger Points – by improving circulation to
them.
Ø
Balancing
Acupoints in the ear and body.
Ø
Re-Balancing
the Nerve System.
The
above effects can help us achieve faster results during
detoxification, emotional stress, and stabilizing spinal
dysfunction
(holding
your adjustments longer).
