Yousefi-Nooraie R et al. - Low level laser therapy (LLLT) is used by some physiotherapists to treat LBP. LLLT is a non-invasive light source treatment that generates a single wavelength of light. It emits no heat, sound, or vibration. It is also called photobiology or biostimulation. LLLT is believed to affect the function of connective tissue cells (fibroblasts), accelerate connective tissue repair and act as an anti-inflammatory agent.
