Lasers are a great technology to hlep decrease pain, improve movement, and speed the healing process. 

This is the MR4.  Make sure you are getting the best in laser therapy, and not being treated by inferior laser technology.

...The super pulsed GaAs (diodes) in GaAs lasers give deep penetration without the unwelcome effects of Continuous Wave (lasers) such as thermal damage, as well as allowing for shorter treatment times.

I often get a lot of questions on laser therapy and how it works, so I've put together a summary of many of the studies and most important pieces of information from those studies.  I am constantly reviewing the PubMed peer reviewed research for new studies to make available here.

Here is the information I have gathered on low level laser and LEDs and their benefit on healing  damaged, degenerated and injured tissues:
  1. The LEDs at specific wavelengths are reported to increase circulation by increasing the formation of new capillaries. New capillaries speed up the healing process by carrying more oxygen as well as more nutrients needed for healing and they can also carry more waste products away.
  2. Collagen is the most common protein found in the body and the essential protein used to repair damaged tissue and to replace old tissue. Studies cite that LEDs stimulate the production of collagen. It has been reported that by increasing collagen production, less scar tissue is formed at the damaged site.
  3. Increases lymphatic system activity. Edema has two basic components, liquid and protein. Research has shown that the lymph vessel diameter and the flow of the lymph system can be doubled with the use of light therapy. This means that both parts of edema can be eliminated at a much faster rate to relieve swelling.
  4. Reduces the excitability of nervous tissue. The light energy stimulates the release of endorphins which are the body's own long term pain fighting chemicals.
  5. Stimulates fibroblastic activity that aids in the repair process. Fibroblasts are present in connective tissue and are capable of forming collagen fibers.*
  6. Stimulates tissue granulation and connective tissue projections, part of the healing process.
  7. Helps relax muscles.
