LLLT is the use of lasers for biostimulatory purposes. Instead of cutting tissue as with a surgical laser which uses much more power (watts), LLLT uses lasers with power outputs in milliwatts. This is important to understand, as the conditions that can be treated with LLLT are many. Research continues to amount as more and more practitioners have started using this effective therapy.
LLLT typically uses lasers in the infrared range as this allows for penetration through a patient's skin to reach the area of treatment. This therapy has been used to successfully treat low back pain, neck pain, shoulder pain, and joint pain depending on the exact pathology. LLLT can also be used to decrease healing time of fractures and wounds.
