ABSTRACT
Most physicians have never heard of low-level light therapy (LLLT)
or the recently accepted term photobiomodulation (PBM), and yet
there are already over 1,000 devices on the world market to choose
from (Alibaba, 2015). Device prices range for $100 to $100,000,
and many claim to have been appointed the European CE Mark, a
few dozen have FDA clearance, some have TGA for Australia, Health
Canada, and JPAL clearance for Japan, but relatively few of those
devices been tested in published clinical trials.
