Low Level Laser Therapy (or LLLT) is one of the most well researched and supported treatment modalities that is available. It is increasingly used and as effective means of pain relief, tissue regeneration and wound healing.
LLLT delivers a low level of cold light (or photonic
energy that does not produce heat) to an area of pain so that the target tissue can
The principle behind LLLT is that it stimulates mitochondrial function within a cell.
Mitochondria drive the chemical energy needed to power a cell’s biochemical
reactions. Mitochondria are the powerhouses within cells, and they convert chemical
energy from the food we eat into an energy form that the cell can use.
The chemical currency that mitochondria generate is known as adenosine
triphosphate (or ATP). ATP thus provides energy for all the reactions needed within a
cell. Different cells have different quantities of mitochondria. For instance, muscle
cells are rich in mitochondria.
Mitochondria also have a role is breaking down any damaged cells, a process known
as apoptosis). They also store calcium which is important to normal muscle function
and blood clotting. Calcium is also important in initiating the release of
neurotransmitters from nerve cells or hormones from endocrine cells.
By increasing the energy available to a cell in the readily accessible form of ATP,
laser light can greatly stimulate the biological function of cells, tissue, and systems
and even raise overall vital energy throughout the individual.
Laser therapy has been demonstrated to stimulate the regeneration of bone, blood,
the lining of blood vessels, cartilage, cochlear hair cells, central and peripheral
nerves, and muscle. It has also been well documented that it enhances the speed of
wound healing. Laser therapy may be an ideal treatment. It may not only effectively
address many medical conditions but also has been widely reported to improve
health and wellbeing as evidenced by a host of biological markers.
There are thousands of research papers on laser, and even the review papers
exceed 1200, so it is all but impossible to list all applications and all research
evidence in this summary. LLLT has been shown to be particularly effective in the
