Low-Level Laser Therapy (LLLT) is a light therapy frequently used to treat musculoskeletal injuries.
What Laser Therapy can do.
Speeds wound healing
Laser Therapy accelerates healing, improving the repair, remodeling & regeneration of horse tissue. Laser therapy heals wounds, manages pain ,ligament and tendon injuries, torn muscles as well as acupuncture point stimulation. Laser therapy decreases pain, inflammation, heals whilst increasing the tensile strength of ligament and tendons returning them to normal function. Laser Class Lasers are classified depending on the power (mW or W) or energy of the beam and the wavelength (nm) of the radiation emitted.
Laser class is based on the laser’s potential for causing injury to the eye or skin. Laser Class has nothing to do with the efficacy of the treatment. The laser class ranges from Class 1 to Class 4, depending upon output power.
Therapeutic Laser Therapy
With equine therapy, the majority of laser therapy units are either a Class 3b or Class 4 laser. Current scientific and clinical research indicates that Class 3b lasers are best for therapeutic applications and Class 4 lasers are best suited for tissue destruction. Laser light is delivered in wavelengths ( measured in nanometers).
Laser light is highly absorbed by water (humans and animals are at least 60% water) at wavelengths greater than 950 nanometers (nm). 99% of this energy is absorbed before penetrating the skin, leading to a high risk of thermal damage (burns) and a low depth of penetration. Class 3b lasers maximum wavelengths are generally below 950 nm. Class 4 lasers generally have wavelengths up to 980 nm. It has not been proven in scientific literature that higher power is better. It is, in fact, the opposite.
There is a therapeutic “optical response” window between 600 nm and 950 nm with the maximum effect range from 650 – 930 nm. In other words, just because a laser is more powerful and can be treated faster, does not always make it better.
What is extremely important is the knowledge and expertise of the person operating the laser. You want them to have a thorough knowledge of equine anatomy, equine medicine and the operation of the laser.
