Low back pain is a highly prevalent condition worldwide. Many non-pharmacological therapies are available for the treatment of low back pain, which aim to reduce pain and disability. Photobiomodulation therapy is one such therapy. It is defined as a non-thermal and non-ionising light therapy, so it is mainly applied in the form of low-intensity laser or light-emitting diodes (LEDs).

A recent systematic review aimed to summarise the effects of photobiomodulation therapy on pain and disability in people with non-specific LBP, when compared with control conditions (such as minimal intervention, placebo and no treatment) and other interventions, and when used as an adjunct to other treatments.
