Cold laser therapy can be an effective treatment for injuries used on its own or as an adjunct treatment to Osteopathic manipulation, therapeutic exercise, and manual therapy. It’s effects are more profound and last longer when combined with other therapies. Usually Laser light therapy is applied for 10 to 20 minutes per session depending on location of treatment, severity of problem and type of injury or condition.
What can be treated?
Lasers are effective treatments for many conditions. The following is a list of conditions that are very responsive to laser treatment and ones that we commonly treat at our clinic:
- Inflammation of joints in such conditions as arthritis, repetitive strain and injury, Knee meniscal injuries
- Nerve injury neuritis, neuropathic pain, Neuropathy, Sciatica
- Carpal Tunnel syndrome, Thoracic Outlet syndrome, Pinched nerves
- Damaged ligaments and chronic tears leading to joint instability and pain (Tennis Elbow, Golfer’s Elbow)
- Damaged tendons, Plantar Fasciitis, Tendonitis and Tendonopathy, Rotator Cuff Tear, Shoulder Impingement Syndrome
- Non-healing skin lesions such as venous stasis lesion or ulcerations
- Pain (laser light is very effective at reducing pain)
- Acute and Chronic Injuries (laser light speeds up healing)
What is the Science?
Modern science has shown that specific wavelengths of laser light have particularly strong healing properties. Cellular tissue repair and pain reduction can occur by focusing laser light on affected body areas at frequency levels of between 600nm and 1,000nm (nanometers).
What does Therapeutic Laser Light Therapy Do?
- Increased Vascularity (circulation) by increasing the formation of new capillaries. New capillaries speed up healing by supplying additional oxygen and nutrients needed for healing.
- Stimulate the production of collagen. Collagen is the most common protein found in the body. Collagen is needed for repair in replacing damaged tissue. Increasing collagen production will decrease scar tissue at the injured site.
- Stimulate the release of ATP. ATP is the major carrier of energy to all cells. Increases in ATP allow cells to readily accept nutrients and expel waste products faster by increasing the energy level in the cell. All food turns into ATP before it is utilized by the cells. ATP provides the chemical energy that drives the chemical reaction of the cell.
- Increase lymphatic system activity. Research has shown that the lymph vessel diameter and flow of the lymph system can be doubled with the use of light therapy.
- Increased venous diameter and increased arterial diameter occurs during light therapy.
- Increased RNA and DNA synthesis. This helps damaged cells to be replaced more promptly.
- Reduce the excitability of nerve tissue. The photons of light energy enter the body as negative ions. This requires the body to send positive ions, calcium among others, to flow to the area being treated. These ions assist in regulating the nerves, there by relieving pain.
- Stimulate fibroblastic activity which aids in the repair process. Fibroblasts are present in connective tissue and are capable of forming collagen fibres.
- Increase phagocytosis, which is the process of scavenging for and ingesting dead or degenerated cells by the phagocyte cells. This is an important part of the infection control process. The healing process depends upon the destruction of infection and the clean up of cellular debris.
- Induce a thermal effect in the tissue. Laser light raises the temperature of the cells although there is no heat produced from the laser light diodes themselves.
- Stimulate tissue granulation and connective tissue projections, which are part of the healing process of wounds, ulcers or inflamed tissue.
