Understanding How Cold Laser Works

Often, people with acute or chronic pain (low back pain, a sore knee, or persistent neck stiffness) will quickly turn to over-the-counter pain medicine for relief.  However, the FDA recently issued strict warnings regarding the misuse and overdosing of over-the-counter pain medications due to severe complications such as stomach ulcers, hearing disorders and liver failure. In addition, there is a growing concern among physicians regarding the side effects associated with prescription pain medication.

So how can low-level laser therapy help?  Low-level laser therapy (LLLT), or cold laser, is a painless, sterile, non-invasive, drug free modality that is used for a variety of conditions such as acute and chronic pain, post-operative pain, shoulder pain, etc.

Housed within the mitochondria, the cell energy manufacturer, are receptors capable of absorbing distinct parameters of light.  Think of these receptors like any drug receptor.  When we consume a medication, the compound is absorbed by the body and it locates a particular receptor, based upon its molecular design, and will bind to that receptor.  Once the drug binds, a secondary reaction inside the cell takes place.  

A similar mechanism is observed when exposing the body to a particular color of light.  During a laser treatment, the light will penetrate the skin and is absorbed by this receptor within the mitochondria.  Receptor stimulation with light promotes energy production, biochemical reactions, protein and growth factor synthesis, cell growth and proliferation and enhancement of blood and oxygen flow.

   The result ā€“ more rapid healing and relief ā€“ nothing heals faster.  What this means to you is that in just a short time you could be pain free and able to resume the activities you enjoy.
