Low level laser therapy (LLLT) is the use of a focused beam of non-heating light to treat human illness and injury. The suggested physiological effects of laser therapy include increased ATP synthesis, increased cell proliferation, microcirculation activation and analgesic effects just to name a few (1). LLLT includes instruments utilizing a variety of wavelengths and power outputs.
