Baseline Testing

ImPACT (Immediate Post-concussion Assessment and Cognitive Testing) is a sophisticated, research based computer test developed to help clinicians evaluate an athlete’s recovery following concussion. ImPACT is a 20 minute neurocognitive test battery that has been scientifically validated to measure the effects of sports related concussion. In the preseason, each athlete is given a baseline test. And, when a concussion is suspected, during the season, a follow up test is administered to see if the results have changed from the baseline. This comparison helps to diagnose and manage the concussion. Follow up tests can be administered over days or weeks so clinicians can continue to track the athlete’s recovery from the injury.

About ImPACT

Founded by the University of Pittsburgh Medical Center’s Sports Concussion Program, this software system is utilized throughout professional sports and has been mandated in the NHL. Used by 18 NFL teams, US Soccer and countless colleges and high schools across the country, it is fast becoming the “Gold Standard” in recognizing and managing head injuries.

The exam takes about 25-30 minutes and is non-invasive. The program is basically set-up as a “video-game” type format. It tracks neurocognitive information such as memory, reaction time, brain processing speed, and concentration. For example, in one part of the exam, a dozen common words appear one at a time on the screen for about one second each. The athlete is then later asked what words were displayed. It is a simple exam and most who take it enjoy the challenge of the test.

The Impact Baseline test is ideally administered under the supervision of a clinician, athletic trainer, coach, or even a parent. It is important that the athlete is able to put forth their best effort to make sure the baseline test will accurately register their pre concussive norms.

In the event that baseline testing is not possible, ImPACT has a normative database of thousands of non-injured athletes, and such data can be used effectively for adequate comparison and safe decisions for return to play.

Athletes should NEVER TAKE a SECOND BASELINE test after an injury. It falsely identifies post-concussion data and symptoms as pre concussion baseline norms and could cause diagnostic errors. Instead, a Post Injury Test should be taken following an injury where concussion is suspected.
