SPINAL ATAXIA
In the movie The Lord of the Rings, Gollum was a computer-generated creature whose movements were created by filming an actor with reflective markers attached to his body. This same technology is being used at the University of Missouri-Columbia's College of Veterinary Medicine to develop a competent test in diagnosing spinal ataxia, which is a symptom of several deadly diseases in horses and can cause lameness.

"Spinal ataxia is the inflammation of the spinal cord and makes the horse uncoordinated, making it very difficult for the horse to walk," said Dr. Kevin Keegan, an associate professor of veterinary medicine and surgery. "A handful of diseases cause spinal ataxia, but the problem is that spinal ataxia is very difficult to diagnose in its early stages. That is where our computer system helps."
