Laser is the most advanced, effective, and non-invasive
form of therapy. Low Level Laser is the treatment of
choice for pain control and tissue healing in
rehabilitation medicine. It is safe, painless and
results are remarkable with no radiation or side
effects. Here are some commonly asked questions about
Laser Therapy.
What is Low Level Laser Therapy?
Low Level Laser is coherent, monochromatic light which
has the ability to heal. Laser Therapy provides light
energy to treat an injury to soft tissue such as a
ligament, tendon or muscle. The biological effects of
Laser Therapy have been used clinically for over 40
years, and Health and Welfare Canada approved the
clinical application of lasers 14 years ago.
How does it work?
Laser heals tissue by stimulating the molecules in the
cell with photons or light energy. The basic principle
is that the photon energy in the light emitted by the
laser is incorporated into the natural process of the
living cells. Research shows that this energy is
absorbed by the cell and is converted into complex
biochemical substances that provide biostimulating
effects – the basis for reducing pain and inflammation,
healing the cell and restoring it to normal function.
Is Low Level Laser Therapy scientifically well
documented?
Yes. There are more than 100 double-blind positive
studies confirming the clinical effect of the Low Level
Laser Therapy. More than 3000 research reports are
published.
What are the benefits of Laser Therapy?
Low Level Laser Therapy speeds up recovery from a recent
injury to a ligament, tendon or muscle. It reduces pain,
swelling and promotes healing. It can also be used to
treat an old injury in one of these structures. Injury
to a muscle leaves behind residual scar tissue which
causes the muscle to shorten and work less efficiently.
Laser can help break down this scar tissue, allowing
exercises to be done to stretch and strengthen the
muscle, thereby reducing the risk of further strain and
preventing other injuries.
What conditions does Low Level Laser Therapy help?
Low Level Laser Therapy can treat a variety of
conditions. Common conditions treated with Laser Therapy
are: back and neck pain, sports injuries, arthritis,
tendon/ligament problems, carpal tunnel, nerve root
irritations, tennis elbow, bone spurs, rotator cuff,
swelling, spasm, repetitive stress injuries, wound
healing, acute/chronic pain or post operative pain with
or without surgical metal implants, and other related
conditions.

What is expected in a Laser Therapy session?
Treatments are short and painless. The average
number of treatments are 8-10 sessions for acute
conditions and 18-20 sessions for chronic
conditions. Low level lasers do not generate
heat. Therefore, when the probes contact the
skin, the patient experiences no sensation.
Physiological Effects of Low Level Laser Therapy
Short Term Effect – Pain Control
· Production and release of beta-endorphins (these are
morphine like substances produced by various
cells in the body that inhibit the sensation of
pain)
· Increased production of cortisol (cortisol is the
precursor of cortisone). This enables the body
to combat the stress associated with the painful
conditions.
Long Term or Cumulative Effect – Healing of Tissue
· Increase ATP (adenosine triphosphate) production resulting
in improved cellular metabolism.
· Stimulate DNA (deoxyribonucleic acid) production,
substantially increasing the protein building
block of tissue.
· Facilitate neurotransmission by elevating levels of
serotonin and acetycholine.
· Promote mitochondrial activity resulting in cell
replication.
· Modulate macrophages, fibroblasts and other cells.
· Regulate cell membrane potential, essential in ion
transfer (electrolyte balance)
· Enhance cellular communication by releasing cytokines and
other chemicals.
Other Effects
· Stimulate immune response.
· Improve lymphatic drainage.
· Positively alter the histamine response.
· Increase production of growth hormone. |
