Trevor S. Berry, Paul J Quarneri, Gregory Roche and Travis M Sammons

Low back pain is the leading cause of disability, with an estimated 632 million persons worldwide suffering and
producing societal costs exceeding $100 billion annually in the United States. The use of low-level lasers (LLLT) has
demonstrated beneficial effects for treating a range of painful musculoskeletal conditions, including low back pain. The
Food and Drug Administration granted LLLT the first 510(k) market clearance for the treatment of chronic low back
pain (K180197), based off a randomized, double-blind, sham-controlled study. The objective of the following study
was to reassess the safety and efficacy of LLLT in these same subjects 12 months after receiving LLLT for chronic
low back pain.
