On the sidelines, the test can identify athletes that not only have suffered a full-blown concussion but sub-concussive brain trauma as well. Thus, the test is an excellent "remove-from-play" tool for trainers, coaches and parents. An effective remove-from-play tool is critical because it can help prevent Second Impact Syndrome, a condition in which a person experiences a second brain injury shortly after the first. Second Impact Syndrome can have devastating effects, including death.

"For every one concussion that you see we identified, there were six concussions that were not seen and were not being reported."
The results took him by surprise. Mr King tested more than 100 Wellington premier rugby and league players over three years using what's called a saccadic reading test, which he calls his number-one tool. Players do a baseline reading pre-season and again after the games.

“For decades, optometrists have used the King-Devick test to aid in the diagnosis of ocular motor dysfunction and a need for vision therapy,” says Marc Taub, OD, MS, FAAO, FCOVD, chief of vision therapy and rehabilitation and supervisor of the residency program in pediatrics and vision therapy at Southern College of Optometry. “It is reliable and easy to perform in patients of any age or cognitive ability.

“It’s about that Jell-O within that cranium,” says Dennis Cardone, an associate professor of orthopedic surgery at Langone Medical Center, and co-director of NYU’s Concussion Center. “How it moves around, and how it collides with the cranium itself.” Because a significant proportion of our brains is used to process visual information, many of the symptoms that can be used to diagnose concussions affect vision. Cardone uses a screening test called the King-Devick test, which was developed in 1976 to measure deficiencies in eye movement during reading.

The King-Devick Test is one method Clugston and his team have used since 2011. The test is a two-minute challenge that requires an athlete to read single-digit numbers displayed on cards or on an iPad. UF collects baseline data for the King-Devick Test as with all of its concussion tests, and if an athlete is suspected of suffering head trauma, he or she is re-tested. If the time needed to complete the test is any longer than their baseline result, the athlete is removed from play and further evaluated.

Dr. Kurt Miceli, Medical Director of Bancroft, a neurological rehabilitation facility says it could prevent more injuries. “I’ve seen numbers one and a half million up to three million concussions a year, tremendous amounts of folks who are undergoing these concussions and the concern is to really have our kids or whoever it is not to suffer a second one.”

The simple assessment, which doesn't require medical knowledge to conduct or evaluate, may be especially useful in the youth sports arena where trainers and team physicians are few and far between. The rapid, low-tech evaluation may also help keep injured athletes from re-entering play and risking second impact syndrome, which can be fatal.

“We want to make sure that those communities that have very few resources for sideline detection can get some,” Robert said. “If we can do that for our schools — have a quick way to perform the test and have it interface seamlessly with a report to this office and perfect permanent record — then we have really made a contribution to detection and aftercare of our students.”

Take Home Message: The King-Devick test is a quick and reliable method to assess vision, eye movements, language function, and attention. An athlete with a concussion tends to complete the test slower than his/her preseason assessment while other athletes improve over time.
