Why Laser Therapy Heals & Relieves Pain


Laser therapy uses focused red and infrared light to stimulate tissue at and below the skin surface. In the simplest terms, laser therapy uses light energy to heal the body from within on a cellular level. Laser therapy uses a beam of light to penetrate tissue, absorbing into the cell without damaging it and inducing a response called “Photo-bio-modulation,”which helps reduce pain. It is non-surgical, non-invasive, and painless. During each treatment, energy from the laser increases circulation, drawing water, oxygen and nutrients to the damaged area. This creates an optimal healing environment that reduces inflammation, swelling, muscle spasms, stiffness and pain. It can also accelerate tissue repair and cell growth, reduce scar formation and help the immune system fight off infection. 


Some of the well-known biological effects of laser are cartilage stimulation, production of fibroblasts (the cells that create healing tissue), enhancement of immune cells to combat pathogens, and increasing the blood supply of the healing tissue.

Why laser therapy works:

  • Decreases inflammation and edema (enhances white blood cell activity and lymphatic drainage strengthens cells)

  • Stimulates cartilage production and nerve regeneration

  • Accelerates wound healing and tissue repair (stimulates collagen and fibroblast production)

  • Increases circulation (important to healing)

  • Decreases pain by stimulating hormone activity (produces endorphins and releases serotonin)

  • Relaxes muscles

  • Stimulates acupuncture points



Why laser therapy works:

  • Arthritis (degenerative joint disease)
  • Post-surgical pain

  • Wound and trauma to the skin, muscle, or bone


Other indications for laser therapy include muscle spasms, trigger points, areas of decreased circulation, inflammation, scar tissue, contracture, and joint swelling. Improvement is sometimes seen after the first treatment; however, most pets require several treatments to achieve maximum benefits.
