Low-level
Low-level laser therapy (LLLT) is a form of alternative medicine that uses low-level (low-power) lasers or light-emitting diodes (LEDs) to alter cellular function. LLLT is controversial in mainstream medicine with ongoing research to determine whether there is a demonstrable effect. Other names for LLLT include cold laser therapy, photobiomodulation, soft laser, biostimulation, and photonic stimulation.
History[edit | edit source]
The use of low levels of visible or near infrared light for reducing pain, inflammation and edema, promoting healing of wounds, deeper tissues and nerves, and preventing tissue damage has been known for almost forty years since the invention of lasers.
Mechanism of action[edit | edit source]
The effects of LLLT appear to be limited to a specified set of wavelengths of laser, and administering LLLT below the dose range does not appear to be effective.
Medical uses[edit | edit source]
While evidence for the use of LLLT in osteoarthritis is inconclusive, it has been suggested for use in temporomandibular joint disorders.
Safety[edit | edit source]
The application of LLLT has been shown to be safe in animal studies and a variety of human trials.
