Laser therapy can be divided into contact and scanning therapy and both modes can employ monodiodic and multi-diodic lasers.
As far as laser therapy carried out with monosodico contact lasers, probes with direct contact on the skin are employed.
The treatment is based on the stimulation of the trigger points or of the areas affected by pain and the therapy requires the presence of one operator. The most important working parameters within laser therapy are power density (power released per density of the irradiated tissue, which is measured in W/ sq cm and is calculated dividing the output power for the irradiated spot dimension). Fluency is the most important parameter for determining the clinical effect of the laser since it easures the quantity of energy released per unit of irradiated tissue area. It is measured in J/sq cm2 and it is calculated multiplying the power density by the exposition length. Each protocol supplied by Medical Italia indicates the fluency suggested for each kind of treatment. The operator, according to the area to treat and to the laser power, will modify the treatment time or the frequency, in order to convey the necessary fluency for the treatment.
