- Visual attention deficits
Comprehensive treatment for traumatic brain injury
新澳门六合彩内幕信息 Davis experts in physical medicine and rehabilitation, sports medicine and neuropsychology provide complete care for all forms of traumatic brain injury from mild to severe. Treatment plans are personalized based on the causes of the injury and specific symptoms. Call 916-734-6805 for information about sports-related TBI (including concussion) treatment and return-to-play evaluations and 916-734-7041 for information on non-sports-related TBI evaluation and treatment.
, director of neuro-ophthalmology at the 新澳门六合彩内幕信息 Davis Eye Center, has found a way to more objectively determine the likelihood of a concussion by measuring how athletes鈥 eyes react to specific tests that assess the eye-brain connection.
鈥淭his is what I consider groundbreaking research,鈥 says , head team physician for and assistant clinical professor of orthopaedic surgery. 鈥淩ight now, whatever an athlete tells me is what I have to go on with regard to concussion, because you cannot see concussion.鈥
Moore is the principal investigator of a study that began this fall on the 新澳门六合彩内幕信息 Davis football field. She is using the device to test athletes immediately after a sports injury and assess how their brain function compares to established norms.
Returning to play too soon creates risks
Returning to play too soon after a concussion creates risk of more serious injury or even sudden death. Currently, athletic trainers, physicians and professionals try to detect brain injury in players by having them take balance and cognitive tests prior to the start of the sport season, and then give the same tests at the time of injury. If the player performs poorly compared to his baseline test, then a concussion is suspected.
But existing tests are inadequate because a concussion diagnosis still relies partly on the self-reporting of players who may want to return to the game. They can fudge the results by purposely delivering a poor baseline test so that when an injury occurs, their results aren鈥檛 too different from their baseline scores.
鈥淭herein lies a really big problem, because you鈥檙e going to get people who are really hurt, but they鈥檙e competitors, and they want to go out there, but it may not be safe to do so,鈥 Khaderi says. 鈥淩eturning to play too soon after a concussion increases the risk of more serious injury and even sudden death from rapid brain swelling if the first concussion hasn鈥檛 had time to heal.鈥
Tool measures eye tracking, pupil dilation, brain waves
Khaderi and his team have identified three tests that will run on a laptop or tablet platform and can greatly increase chances of accurate on-field assessment. One test gauges eye movement 鈥 which often slows after brain injury 鈥 and compares it against a baseline that鈥檚 harder for players to intentionally throw.
Another test measures pupil dilation and function via responses to image-driven psychological tests, rather than by classic flashlight-in-the-eyes techniques that can be skewed by background light. A third metric in the works measures brain waves, or electroencephalograms.
鈥淚 wanted to create something that was cheat-proof. And to do that, I focused on eye movements and pupil response 鈥 physiologic processes that you can鈥檛 cheat,鈥 Khaderi says.
Packaged as cloud-based software application
Measuring eye movement can be accomplished with a $100 eye-track instrument and a laptop or tablet. Khaderi says he hopes to package this test in a cloud-based software application, making it accessible to coaches and team physicians at all levels of play.
鈥淲e wanted to keep this as cheap as possible in terms of making sure that we can get it into the hands of the people that need it,鈥 he adds.
