Mike Gundy reaffirmed Monday that he was optimistic that Justin Blackmon will play Saturday against Baylor after being held out of the second half of OSU's win at Missouri last week because he got “dinged” in the head.
But Blackmon will still undergo a series of concussion tests Tuesday morning and will be evaluated by Val Gene Iven, OSU's head team physician.
OSU administers a four-part test to all athletes involved in football, basketball, wrestling, equestrian, baseball and softball when they arrive on campus to use as an individual baseline score. If a head injury occurs, the athlete must retake the tests and score within 10 percent of all of their baseline marks before returning to practice.
OSU developed its protocol for testing for concussions about six or seven years ago. It's mostly modeled after the philosophies of Kevin Guskiewicz, a leading researcher in the diagnosis and treatment of sports concussions at the University of North Carolina
“When there is a brain injury that occurs in sports, they often act much different than if you were in a car wreck or something like that,” said John Stemm, OSU's director of athletic training. “Very, very seldom will you have any loss of consciousness in the sporting world. Our grading criteria is a little bit different.
“There are a lot of people that have done a lot of research that have tried to gear it a little more toward sports, because in the old criteria, it was based on loss of consciousness and not loss of consciousness.”
Here is a breakdown of those tests.
The athlete will rank the severity of 16-18 symptoms on a scale of zero to six, with zero meaning no symptoms and six meaning severe symptoms. These include headache, sensitivity to light, confusion and disorientation, amnesia, irritability and balance issues
Time: One minute
2. BESS Test
This test checks the athlete's balance, both on solid ground and while standing on a rectangular piece of foam.
Time: Five minutes
3. SAC Test
This is a cognitive test that focuses on memory and recall.
Time: Five minutes
4. ImPACT Test
This is a computer-generated test that is similar to the SAC test. It uses shapes, colors, words and other elements to measure speed, errors and recall.
Time: 25-30 minutes
