Physiological Effects of Low Intensity Laser Therapy

Short Term Effects

• Production and release of beta-endorphins (these are morphine-like substances released by cells in the body that inhibit the sensation of pain)
• Promotes the synthesis of collagen (one of the key building blocks of muscle, ligaments and tendons)
• Activates other important cells (e.g. keratinocytes, endothelial cells)
• Cortisol production is increased (cortisol is the precursor of cortisone). This enables the body to combat the stress associated with trauma or the disease process
• Increased oxygen in the area of healing

Long Term or Cumulative Effect

• ATP (adenosine triphosphate) production is increased, resulting in improved cellular metabolism
• DNA (deoxyribonucleic acid) production; the protein building block of tissue is substantially increased
• Improves transport of nutrients into the cell (e.g. calcium and potassium)
• Generates new blood vessels (angiogenesis)

Other Effects

• The immune response is stimulated
• Lymphatic drainage is improved
• The histamine response is positively altered
• Production of growth hormone is increased
• The body's natural healing processes are enhanced

Non-Chiropractic Uses

Laser Therapy is also used by:

• Dentists to treat damaged oral tissue.
• Dermatologists to treat ulcers, burns, edema, and dermatitis.
• Rheumatologists for the relief of pain, and treatment of chronic inflammatory and autoimmune diseases.
• Sports medicine and rehabilitation centers to decrease pain, reduce swelling and improve function.
