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:
