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 – more rapid healing and relief – 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.  

Are You Confused by Cold Laser Therapy?

Whenever a treatment is not fully understood, there are skeptics. It is good to be skeptical, but an open mind helps too!

Cold lasers do not generate heat. The FDA has approved the technique, and studies have shown it to be an effective short term treatment for pain. However, there are still questions regarding how and why the therapy works.

Multiple studies have demonstrated that low level laser therapy helps relieve pain, sometimes in instances where other methods of pain relief have not worked.

The range of options for treatment have caused some questions, as LLLT can include a variety of wavelengths, intensities, number of treatments, and other variables. In simple terms, light causes a photochemical response in the cells, particularly the mitochondria. The same process can be observed in nature: photosynthesis is an example most people understand. LLLT causes a similar biological response within cells, creating a regenerative effect that is especially useful for treating pain caused by injury, or illness impacting the nervous system.

Cold lasers are non-invasive. They emit no heat, sound, or vibration, though some people report a tingling sensation when I use it on them. Sometimes nothing appears to be different or happening. Hot lasers, which destroy tissue, can clearly be observed. It’s easy to understand why skeptics argue that cold lasers are ineffective.

I have used my cold laser extensively on myself, family and friends, all with positive results. While the animals I use it on cannot report to me with language, their improvement in movement speaks for itself.



Low Level Laser Therapy

Low Level Laser Therapy, also known as Cold Laser Therapy, has been in use for over 40 years, but was finally approved by the FDA in 2002. Laser therapy has primarily been used to relieve pain, heal wounds and scar tissue, and regenerate nerves.

There are over 2000 published studies on the cold laser showing absolutely 0% negative side effects. What drug can show the same results?

Cells in the body produce a chemical known as ATP (adenosine tri-phosphate) to run the body and heal tissue. All of our body’s activities result from the use of ATP.  Low Level Laser Therapy stimulates a structure within the cells called the mitochondria to produce slightly higher amounts of ATP. With more ATP at the cell level, tissues heal faster, and relief comes faster.

Four to twelve treatments may be needed for complete healing of an injury or relief of pain, but I have found major relief after just one session with the laser.
