KNOWN BIOLOGICAL
EFFECTS OF LASER
THERAPY- (LT)
Clinical studies
and trials of
laser therapy
technology
indicate the
following
beneficial
effects of laser
light therapy on
tissues and
cells:
1. Accelerated
Tissue Repair
And Cell Growth.
Photons of light
from lasers
penetrate deeply
into tissue and
accelerate
cellular
reproduction and
growth. The
laser light
increases the
energy available
to the cell so
that the cell
can take on
nutrients faster
and get rid of
waste products.
As a result of
exposure to
laser light, the
cells of
tendons,
ligaments and
muscles are
repaired faster.
2. Faster
Wound Healing.
Laser light
stimulates
fibroblast
development
(fibroblasts are
the building
blocks of
collagen, which
is predominant
in wound
healing) in
damaged tissue.
Collagen is the
essential
protein required
to replace old
tissue or to
repair tissue
injuries. As a
result, LT is
effective on
open wounds and
burns.
3. Reduced
Fibrous Tissue
Formation.
LT reduces the
formation of
scar tissue
following tissue
damage from
cuts, scratches,
burns or
surgery.
4.
Anti-Inflammation.
Laser light
therapy has an
anti-edemic
effect as it
causes
vasodilation,
but also because
it activates the
lymphatic
drainage system
(drains swollen
areas). As a
result, there is
a reduction in
swelling caused
by bruising or
inflammation.
5.
Anti-Pain
(Analgesic).
Laser therapy
has a high
beneficial
effect on nerve
cells which
block pain
transmitted by
these cells to
the brain and
which decreases
nerve
sensitivity.
Also, due to
less
inflammation,
there is less
edema and less
pain. Another
pain blocking
mechanism
involves the
production of
high levels of
pain killing
chemicals such
as endorphins
and enkephlins
from the brain
and adrenal
gland.
6. Improved
Vascular
Activity.
Laser light will
significantly
increase the
formation of new
capillaries in
damaged tissue
that speeds up
the healing
process, closes
wounds quickly
and reduces scar
tissue.
Additional
benefits include
acceleration of
angiogenesis,
which causes
temporary
vasodilatation,
an increase in
the diameter of
blood vessels.
7.
Increased
Metabolic
Activity.
Laser therapy
creates higher
outputs of
specific
enzymes, greater
oxygen and food
particle loads
for blood cells.
8. Improved
Nerve Function.
Slow recovery of
nerve functions
in damaged
tissue can
result in
numbness and
impaired limbs.
Laser light will
speed up the
process of nerve
cell
reconnection and
increase the
amplitude of
action
potentials to
optimize muscle
action.
9. Immunoregulation.
Laser light has
a direct effect
on immunity
status by
stimulation of
immunoglobines
and lymphocytes.
LT is absorbed
by chromophones
(molecule
enzymes) that
react to laser
light. The
enzyme flavomono-nucleotide
is activated and
starts the
production of
ATP
(adenosine-tri-phosphate),
which is the
major carrier of
cell energy and
the energy
source for all
chemical
reactions in the
cells.
10. Trigger
Points and
Acupuncture
Points.
Laser therapy
stimulates
muscle trigger
points and
acupuncture
points on a
non-invasive
basis providing
musculoskeletal
pain relief.
