Equine lameness is an indication of a structural or functional disorder, in one or more limbs or the spine, evident while the horse is standing or in movement. It can range from very mild discomfort, which may only be perceived by the owner or trainer as a decrease in level of performance, to severe pain in which the horse is unwilling to bear weight on the limb. As one of the most common and most expensive medical problems in horses, lameness represents a large concern to the equine industry as well as to individual horse owners.
