Laser therapy, a very popular therapy in the UK, seems to be now gaining recognition in North America. Laser is an acronym for Light Amplification by Stimulated Emission of Radiation.
Lasers, have been best known for their ability to cut and have been used in the medical field for surgery. However, the laser light for therapeutic purposes is of a much lower power and also of a different wavelength. Lasers do not heat up tissues and usually uses light in the 400 – 1200 nanometer range. This is the light in the infrared range of the spectrum. Light below 750 nm is visible and light about 750 nm is not visible.
Low Level Laser Therapy, commonly known as LLLT (also cold laser, soft laser, LILT) is a form of phototherapy which involves the application of monochromatic (all the same wavelength) and coherent (all the waves peak at the same time or are “phased”) light to injuries and lesions to stimulate healing.
LLLT is used to increase the speed, quality and tensile strength of tissue repair, resolve inflammation, and give pain relief.
Low Level Laser Therapy aims to biostimulate. Because of its low power nature, the effects are biochemical and not thermal and cannot cause heating and thereby damage to living tissue. Three distinct photobiological effects are known to occur when using Low Level Laser Therapy:
1. Healing growth factor response through:
- Increased ATP and protein synthesis
- Improved cell proliferation
- Change in cell membrane permeability to calcium up-take
2. Pain Relief through:
- Increased endorphin release
- Increased serotonin
- Suppression of nociceptor action
3. Immune system support through:
- Increasing levels of lymphocyte activity
- Photomodulation of blood
Low level laser therapy optimises the speed of repair in acute injuries but will also stimulate the body’s repair processes in cases of non-healing or chronic conditions. It is an attractive form of treatment for animal athletes, due to the prospect of shorter recovery and lay-off times.
I use SpectraVetLasers as they offer safe, reliable and effective treatment of musculoskeletal injuries and conditions commonly suffered by performance horses. The portability of battery-powered diode laser systems enables treatment to be carried out in the barn, the trailer, or in the field, allowing the immediate and therefore more effective treatment of equine sports injuries, such as muscle tears, haematomas, and tendinopathies.
