THERAPEUTIC  EFFECTS  of  MEDICAL  LASERS

* All the scientific studies, as well as the clinical works in simple and blind studies, demonstrate effects on the pain, on the inflammation and on the healing.

The basic effect is the conversion of the photonic energy in the tissue by photoelectric effect on proteins. This effect was described by Einstein on metals and he has been granted with  the Nobel of Physics.

A photon of energy E=h µ (in eV) can be reflected, absorbed or transmitted.

The absorbed part is got at the level of proteins by their electrons 'pi'.

The energy of activation supplied by the photons of the laser varies from 1.5 to 2 eV

(from IR to the laser HeNe wavelenght)

Electrons pi absorb this energy in passing of a state normal or perturbed to an excited or normal state according to the  pathological state of departure of the tissue.

Then, this action is ONLY an action of bioenergenitic re-equilibrium of the dalmaged tissue, and can not bring effects of ionization if the wavelengths do not 'fall' towards Ultrat Violet or X-rays.

. In a healthy tissue or normal or becoming again normal after treatment, the electronic population is going to continue to absorb the laser energy but re-emits to more perturbed than it.
The depth penetration inside the tissue of the beam is also a function of the wavelength, the power, and its pathological state.

We will note that the pain, as information, can be stopped or transformed in 2 ways:

- by disappearance of the painful site, by which the bioelectric improvement precedes the biologic improvement

- by disturbance of the transmission of the impulse in the sensitive fibers, by blocking the

polarization / dépolarisation transmittive cycle of the nervous fibers, according to their diameter and to their myelinic insulation.

This result can be obtained with a frequency modulation of the laser, an inverse function of the conduction speed of of the fiber, measurable with an EMG..

This approach seems confirmed by the presence of an bounce effect which increases the pain;

the frequency of modulation, instead of perturbing the transmission, amplifies it by swing effect.

This optical behaviour modification of the tissue gives an information onto the pathological state of

this last one, an then on the dose of energy expressed in Joules / cm2 which is necessary for it to pass from a pathological to a normal state, from a bioelectric point of view.

We can observe this phenomenon when the treatment is made with the optical fibre in  skin contact:

tThe reemission, with a visible laser, which surrounds the optical fibre on a healthy tissue is a disc about 2 cms in diameter and and It becomes insignificant when the fiber finds a pathological zone,

as a sprain or a bruise or an hematoma.

The pathological tissue seems "to drink" the beam but re-emit light after 1or several treatments.

This mode of action, validated by works emanating from scientists among whom certain world specialists of the cellular electroporation , demonstrate the described effects above..

It is necessary to clarify that the intimate action allows to obtain fast results without thermic direct effect on the treated tissue, without side effects and without risk of overdosage

The laser, once the diagnostic has been well established, will bring its quick action, the absence of side effects or intolerances, its aseptic action,the value of the practitioner / patient rapport
This   is  a   therapeutic solution to many pathological cases of inflammation , healing and pain

PRECAUTIONS  for USE

It is, however, imperative: to never aim the beam towards the eyes, the use of protective goggles  

is compulsory for the patient and the practitioner, avoid reflected surfaces like tiles to avoid

reflection of the beam   

and for ethical reasons: people who wear pacemakers,pregnant women,people who have non

identified lesions people who suffer from epilepsy should not be treated
