Low level laser therapy

What is low level laser therapy?

Low Level Laser Therapy ( LLLT ) is a form of phototherapy or light therapy. This involves the application of low power light to areas of the body in order to stimulate healing. It is also known as cold laser, soft laser or low intensity laser.

Controlled research into the effects of low level laser is currently being conducted in various European centres and in Japan.

How does it work?

Photons, which are particles of electromagnetic energy, are emitted from the low power laser. These particles enter the tissues and are absorbed in the mitochondria, which are tiny structures within the substance of each individual cell. The energy is converted to chemical energy within the cell. The permeability of the cell membrane changes which in turn produces various physiological effects. These physiological changes affect a variety of cell types including macrophages, fibroblasts, endothelial cells and mast cells.

What is it used for?

The laser may also be focussed on acupuncture points to assist with smoking cessation and the relief of short or long-term pain.
