Veterinary laser therapy
Amplification of light through stimulated emission of radiation (Light Amplification by Simulated Emission of Radiation) is the concept of the most known acronym in the therapeutic-instrumental field, the LASER.
In the rehabilitation and physiotherapy field the Low Level Laser Therapy (LLLT) is also called also called “Laser Cold” or Laser Low Power, belonging to the Class III of International Laser Classification. In this class are inserted visible or invisible emission lasers that have the ability to repair the tissues through a FotoBioStimolante effect.
The laser pulses act at the cellular level activating the metabolism and the natural repair and regeneration processes, improve vascularization, increase tissue drainage and reduce pain by acting directly at the level of nerve endings. Some devices combine pulses at different wavelengths that reach greater depth in the tissues, maximizing the antalgic, anti-inflammatory and regenerating effect of Laser Therapy.
Laser, through the electrical stimulation of substances having its own energy, is an emitter of luminous electromagnetic radiations characterized by the following properties:
Monochromicity: Emission of a single wavelength
Phase coherence: Radiation phase emission
Directionality: Small angle of divergence of the emitted beam
Brilliance: Emission with high energy density
The specific biological effects that are of extraordinary importance in LASER therapy are:
- Increased ATP production by mitochondrial stimulation
- Acceleration of cellular protoplasmatic electrolyte replacement
- Stimulation of fibroblasts
- Stimulation of angiogenesis
- Stimulation of algotrope terminations, increase in perception threshold and production of beta-endorphins
- Modification of intracapillary hydrostatic pressure, increase of interstitial fluid absorption
- Stimulation of immune systems and increased production of antibodies
The use of LLLT is carried out through direct contact with the skin in the area to be treated (focused treatment); in fact the LLLT does not heat the fabrics. Or by treating the area immediately peripheral to the painful area, making a centripetal or centrifugal displacement with respect to it.
The wavelength of a laser having a biostimulating effect is usually close to infrared and equal to 904-905 nanometers (nm)
The penetration of the laser beam is limited to the very first layers of the treated area;
Helium.Neon Laser direct penetration about 0.8 mm, indirect 10-15 mm
Gallium Arsenide Laser direct penetration about 0.8 mm, indirect 3-5 cm
The unit of energy is the Joule expressed as the application of 1 watt per second.
The power is measured in Watts and therefore corresponds to the relationship between energy and time
The Power Density is expressed as the ratio between the applied power and the surface to be treated measured in cm2
Energy, power, emission mode (direct current or pulse frequency) and application time are the parameters that can be set when performing a laser therapy.
The main effects of Laser therapy are:
- Biostimulation of tissues
- Pain relief
The Laser therefore finds its major applications in rehabilitation and physiotherapy on:
- Muscular and articular pains
- Inflammatory diseases of the MTL system
- Insertion disorders
- Muscular contractions
- Scarring of tissues
- Resorption of edemas
- Adjuvant in the treatment of ulcers, decubitus sores and perianal fistulas
