Laser light has the unique properties of monochromaticity (a single wavelength), collimation (travels in a single direction without divergence) and coherence (with all waves in phase) (Matic et al, 2003). These properties are what allows laser light to penetrate the skin surface non-invasively (Matic et al, 2003; Theralase, 2003; Schindl et al., 1999).

 

Therapeutic lasers are athermic with no appreciable heat transfer (<0.65 °C) so the photonic energy is transferred directly to the target cells and thermal damage is avoided (Matic et al, 2003; Theralase, 2003). Therapeutic lasers use monochromatic light in the 630 to 905 nm range, known as the “therapeutic window” (Stadler et al, 2004).
 

Therapeutic Laser Biological Effects

  • Rapid Cell Growth – Laser light accelerates cellular reproduction and growth.

  • Faster Wound Healing – Laser light stimulates fibroblast development and accelerates collagen synthesis in damaged tissue.

  • Increased Metabolic Activity – Higher outputs of specific enzymes, greater oxygen and food particle loads for blood cells and thus greater production of the basic food source for cells, Adenosine Tri-Phosphate (ATP).

  • Reduced Fibrous Tissue Formation – Laser light reduces the formation of scar tissue following tissue damage from: cuts, scratches, burns or post surgery.

  • Anti-Inflammatory Action – Laser light reduces swelling caused by bruising or inflammation of joints to give enhanced joint mobility.

  • Increased Vascular Activity – Laser light induces temporary vasodilation increasing blood flow to damaged areas.

  • Stimulated Nerve Function – Slow recovery of nerve function in damaged tissue can result in “dead” limbs or numb areas. Laser light speeds the process of nerve cell reconnection to bring the numb areas back to life.

Documented Effects of Laser Therapy

  • Increases Circulation ( Vascularity) - speeds up healing process by producing more oxygen

  • Produces more nitric oxide and other nutrients - increased cell membrane permability & T-cell activity

  • Stimulates adenosine triphosphate (ATP), the major carrier of enery to all living cells

  • Stimulates collagen production - essential protein to repair damaged tissue/ reduce scar tissue

  • Reduces excitability of nervous tissue - assist in decreasing the firing of the nerves thereby relieving pain and restoring proper nerve function to the tissues

  • Increases phagocytosis activity - process of removing dead or damaged cell. Important part of the infection fighting process that destroys infection.

  • Stimulates tissue granulation and connective tissue projections - connective tissue projections, which are part of the healing process of wounds, ulcers or inflamed tissue.

  • Stimulates fibroblast and osteoblast production - aids in repair process of tissue and bone healing

  • Increases lymphatic system activity - reduces inflammation
