COLUMBIA, Mo. The most common ailment to affect a horse is lameness. A University of Missouri equine veterinarian has developed a way to detect this problem using a motion detection system called the "Lameness Locator." Now, Kevin Keegan, a professor of equine surgery in the College of Veterinary Medicine at MU, has found that his Lameness Locator can detect lameness earlier than veterinarians using the traditional method of a subjective eye test.
The Lameness Locator, which is now in commercial use, places small sensors on the horse's head, right front limb and croup, near the tail. The sensors monitor and record the horse's torso movement while the horse is trotting. The recorded information is then transferred to a computer or mobile device and compared against databases recorded from the movement of healthy horses and other lame horses. The computer is then able to diagnose whether or not the horse is lame.
In a new study published in the Equine Veterinary Journal, Keegan and co-author Meghan McCracken, an equine surgery resident at MU, put special adjustable shoes on horses that temporarily induced symptoms of lameness. The horses were then monitored by the Lameness Locator as well as by a number of veterinarians using any lameness testing methods they wished. If no lameness was detected by either the veterinarians or the Lameness Locator, the special shoes were adjusted slightly to increase the symptoms of lameness. This process was repeated until both the Lameness Locator and the participating veterinarians properly identified in which leg of the horse the lameness was occurring. Keegan and McCracken found that the Lameness Locator was able to correctly identify lameness earlier than veterinarians using subjective eye test methods more than 58 percent of the time and more than 67 percent of the time when the lameness occurred in the hind legs of the horse. Keegan attributes this to the sensors' high sensitivity levels.
