LLLT is a newer modality in the field of animal physical rehabilitation. It is a low-Intensity laser that emits intense light at various wavelengths to cause cellular reactions within a tissue. It modulates metabolic activity at a cellular level when the light is absorbed into the tissues and converted to chemical energy. The laser can accelerate tissue repair and aid in wound healing, increase blood flow, accelerate the formation of collagen, and increase the body's pain-control chemicals like endorphins. The therapy is non-invasive and is painless and there is no increase in temperature of the treated areas. It has been used in humans for wound healing and treatment of osteoarthritis and may be valuable in nerve and soft-tissue Injuries as well.
