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.
