Photobiomodulation Therapy (PBMT) in Patients With Low Back Pain (LBP)

Active PBMT will be applied using a device with 152 emitters (wavelength - 808 nm; dose - 3000 J; treatment time - 600 s), in the low back region.

The placebo PBMT will be applied using the same device as that of active PBMT but without any emission of therapeutic dose. Moreover, the irradiated site and the irradiation time were the same as that of active PBMT. Patients received a total dose of 0 J in the placebo mode. The sounds and signals emitted from the device as well as the information displayed on the screen will be identical, regardless of the type of treatment (active or placebo).
