ACTION on PAIN

1. On the free endings level

- by preferential stimulation action of laser emission on the fibers

A alpha , A delta , B beta  against the C fibers , which are nociceptive

2. On the medullar level:

- by the diminution of the secretion of the P substance in the center of the

intermediate neuron in the substancia gelatinosa.

- by increasing of the secretion of the enkephalines, which blocks the receptive

site of the P substance

- by starting the gate control system contolling pain messages by hormonal

feedback - unproven action -

3. On the lesional   level

- by stopping formation of ECPGE prostaglandins which are vasodilatating

and hyperalgesiating substances synthetised and liberated locally in

response to a lesion.

4. On the bioelectric level:

- the low frequencies, in the 5 to 15 Hz range, are responsible for the analgesic action,

ie optimal perturbation of a nociceptive transmission.

- the continuous beam, by quick repolarization of the menbranes of the injured cells,

makes disappear or decrease the painfull signal emission and then the pain intensity

and form.

- these frequencies (CW and few Hz) are the same for use in topic or distal modes.
