Testing & Diagnosis


The Sport Concussion Assessment Tool (SCAT3), developed by a group of international experts, is used to evaluate injured athletes age 13 years and older for concussion. If an athlete completes the test prior to their season, baseline results can be established to determine a patient’s normal responses or reactions. Then, if he or she suffers a concussion the test can be taken again and results compared to evaluate when it is safe to return to play.

The SCAT3 is made up of many different parts and measures immediate memory, concentration, delayed recall, balance, and orientation. Result scores are understood nationwide.


A 25 minute computerized test called ImPACT (Immediate Post-Concussion Assessment and Cognitive Testing) is used to obtain baseline evaluations of neurocognitive functioning (memory, thinking, concentration, and reaction time) as a way to determine safe return to play decisions for athletes. Baseline tests are recommended every two years and can be used in comparison to a repeat ImPACT test if a concussion is suspected to evaluate potential changes or damage caused. The test is available in more than 20 languages.

ImPACT Features:

  • Measures player symptoms
  • Measures verbal and visual memory, processing speed, reaction time, attention span, non-verbal problem solving, and response variability
  • Reaction time measured to a 1/100th of second
  • Assists clinicians and athletic trainers in making difficult return-to-play decisions
  • Provides reliable baseline test information
  • Produces a comprehensive report of test results
  • Automatically stores data from repeat testing
  • Testing is administered online for individuals or groups
  • Compatible with PC and MAC
