Show Me the Light — Laser Therapy

High power laser therapy is not “light”, “cold”, or “low level” therapy. High power laser therapy does work on the same principles as cold or low level therapy but with a more consistent and measurable clinical response on deep tissues and bones.

Class IV (high power) lasers were FDA approved in 2005 in the United States.

Laser has two basic components that determine the function and these are wavelength and power. The laser light in the red and near-infrared range has a positive effect on cells in the body. The light warms up the tissues, crosses damaged cell membranes, excites the mitochondria which makes ATP. ATP is the energy the body needs to repair itself. The light only affects damaged cells and not healthy cells.

The production of ATP (energy) leads to an increase in the following:

  • Cell growth replication
  • Repair
  • Production of enzymes, proteins, immunoglobulins, and other compounds needed by the body

The laser also warms up the tissues, causes muscle relaxation and helps with nerve condition. It can stimulate acupuncture points and can cause other cellular reactions such as:

  • Accelerated tissue repair and growth
  • Faster wound healing
  • Decreased inflammation and pain
  • Improved nerve function and nerve repair

This list is not inclusive of all that a laser can help with but does show a small portion of the possibilities.

Laser power is the rate at which the energy is delivered. The power is associated with the depth of the tissue involved in healing and the deflection of the beam due to the tissues — all of which is physics and makes my eyes roll back in my head. If you want a precise explanation I can send you the handouts but suffice it to say — it works and I love it.

Laser therapy is an effective tool. It has measurable positive results in the following conditions:

  • Arthritis
  • Neck and Back Pain
  • Post-surgical pain/healing/rehabilitation
  • Trauma/fractures
  • Muscle, ligament, and tendon injuries (sprains, strains, and tears)

There are other areas in which laser can have positive results. New research is being conducted in such areas as stimulating stem cells, controlling allergic reactions and maybe even shrinking tumors.

Laser therapy not only accelerates healing but helps with repair, regeneration and remodeling of tissues. It can decrease pain, post-op complications, and has a positive effect on neurologic function. Competitive athletes can recover quicker and regain their edge while family pets can be an active member again. Laser therapy has become an indispensable tool at ARCC — Animal Rehab & Conditioning Center.
