Wavelengths between 632 nm and 905 nm penetrate through the skin, and soft tissues deep enough (2-5 centimeters) to where the light can affect pain, inflammation and tissue repair.

Cold laser therapy has other names including: photobiomodulation, low-level laser therapy, low-power laser therapy, and laser biostimulation.

Patients with muscle injuries like sprains and strains, aches, pains, or who are looking for accelerated wound healing would be candidates for cold laser therapy.

Cold Laser Therapy has roots the early 1900s but it wasn’t until 1967 where a surgical professor in Hungary, Endre Mester, was able to document the first therapeutic effects with laser therapy.

  • What does cold laser therapy do?

Cold laser works by super charging the mitochondria in our bodies.    This makes it easier for our bodies to generate energy FASTER and for use in specific functions in healing.

Benefits of cold laser therapy include:

Accelerated tissue repair and cell growth.

Little particles of light called photons are generated in cold laser therapy.    These photons flood the cells with energy so they can get nutrients faster and get rid of waste. When the cells found in tendons, ligaments and muscles are hit with cold laser therapy, damaged areas heal faster.

Decreased pain.

Cold laser therapy blocks Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP) which are inflammatory markers sent to the brain.    By blocking these markers, cold laser therapy can reduce nerve sensitivity.

  • Risks

Cold laser therapy is very safe and does not have any long-term side effects.    Since cold laser therapy uses a low-power light, treatments are painless, but cold laser therapy isn’t for everyone.

Your doctor might caution against cold laser therapy if:

  • You have epilepsy

  • How you prepare

You do not need to do anything special in order to prepare for cold laser therapy. There are no diet or medication restrictions before or after treatment.

  • before the procedure

During the initial visit, your chiropractor will ask questions about your problem and do an exam. After the exam, your chiropractor will give you a diagnosis, discuss treatment options, answer any questions you may have, or refer you out to another healthcare provider.
The initial visit is the longest due to the need for examination. Subsequent visits are much shorter.

The goals of the evaluation include:

  • Diagnosis of the problem
  • Identify anything that would be a contraindication to care

  • Your chiropractor may also recommend additional tests such as X-rays or an MRI.

Specific tests/procedures you may undergo include:

  • Orthopedic testing
  • Reflex testing
  • Range of motion testing
  • Imaging studies such as x-ray
  • A general health exam

  • What happens during a cold laser treatment?

During cold laser therapy, the practitioner applies a laser device that outputs different wavelengths

and energy levels of light directly to the problematic area. The cells in the area absorb the light and energy and promotes healing.

Treatment in one region takes about 5-15 minutes.

  • After treatment

In some cases, there may be a temporary increase in symptoms.    This is normal and does not indicate injury, it is a sign of healing.

Cold laser therapy is cumulative; so, each session builds upon the previous one.    Typically, acute injuries are treated 2- 3 times a week
