$TLTFF Low Level Laser Therapy (LLLT) is the use of therapeutic (or cold) laser light to provide relief from pain, eliminate inflammation (swelling) or to repair damaged tissues. LLLT is entirely non-invasive and has a wide range of applications, from neural muscular skeletal conditions to wound healing to acupuncture treatments. Rather than destroying tissue, as with surgical (or hot) lasers, LLLT uses low intensity laser light energy to stimulate cells through a number of known cellular pathways in order to encourage tissue healing.
