The term Laser is the acronym for Light Amplification by Stimulated Emission of Radiation. A laser light is monochromatic, collimated, and coherent. A laser is a device that produces such a light. Low level laser therapy (LLLT) is used by some physiotherapists to treat various musculoskeletal condition. 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. Lasers with different wavelengths, varying from 632 to 904 nm, are used in the treatment of musculoskeletal disorders.

Wavelengths between 660 nm and 905 nm have the ability to penetrate skin, and soft/hard tissues. This light have a good effect on pain, inflammation and tissue repair.

Low-level laser therapy:

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 accelerate connective tissue repair and act as an anti-inflammatory agent..

Reduction of inflammation: It can occur within hours to days.
Pain relief : for example pain associated with TMD , pain in tendinopathies or neuropathic pain.
Accelerated tissue regeneration: LLLT stimulates cell proliferation of fibroblasts , keratinocytes endothelial cells and lymphocytes.
Reduction of volume and pain in lymphedema
