The use of laser in therapy and healing has been in existence for more than 40 years. Research is quickly progressing in identifying conditions that can be treated and in therapy laser technology.
Many published studies refer to laser therapy using the technical term photobiomodulation, or PBM. Other studies refer to the use of laser as Low-Level Laser Therapy (LLLT) or High-Intensity Laser Therapy (HILT). Some studies are performed with isolated live tissue samples, some use animals, and some are performed on human subjects.
