What does a Laser Do?
Laser is a form of electromagnetic radiation or light energy that is applied to the body in measured wavelengths that have a therapeutic photobiostimulation effect on the cells. The term Laser is actually an acronym for Light Amplification by Stimulated Emission of Radiation.
There are different powers of lasers. Most people are more familiar with the high powered lasers that are used surgically. These surgical instruments are very precise and used for intricate delicate procedures such as the lasik eye surgery. The low powered kind are used to elicit a photobiostimulation effect which is another way of describing light energy that stimulates cellular function.
Laser has been shown to be helpful for stimulating cellular growth; however, the machine itself cannot restore strength to a weak muscle or flexibility to a stiff joint.
This effect of the laser was first discovered in the late 60’s. An unexpected result of an experiment with laser was accelerated hair growth. Further study of the laser revealed that specific wave lengths of light energy activates the cellular chromophone which increases the respiratory chain enzymes in the mitochondria. This activation of cell activity boosts cell metabolism which contributes to healing and resolving inflammation. The depth that the laser can actually penetrate with therapeutic benefit is unclear; however, the research supports the accelerated growth with dermal (superficial) wounds.
