ImPACT (Immediate Post-Concussion Assessment and Cognitive Testing) is the first most-widely used and scientifically validated computerized concussion evaluation system.
Developed in the early 1990’s by Drs. Mark Lovell and Joseph Maroon, ImPACT is a 20 minute test that has become a standard tool used in comprehensive clinical management of concussions for athletes of all ages. ImPACT Applications, Inc. was co-founded by Mark Lovell, PhD, Joseph Maroon, MD and Michael (Mickey) Collins, PhD.
Given the inherent difficulties in concussion management, it is important to manage concussions on an individualized basis and to implement baseline testing and/or post-injury neurocognitive testing. This type of concussion assessment can help to objectively evaluate the concussed athlete’s post-injury condition and track recovery for safe return to play, thus preventing the cumulative effects of concussion. In fact, neurocognitive testing has recently been called the cornerstone of proper concussion management by an international panel of sports medicine experts.
ImPACT can be administered by an athletic trainer, school nurse, athletic director, team coach, team doctor or anyone trained to administer baseline testing. ImPACT is the most widely used computer based testing program in the work and is implemented effectively across high school, collegiate and professional levels of sport participation.
- Measures players symptoms
- Measures verbal and visual membory, processing speed and reaction time
- Reaction time measured to 1/100th of a second
- Assists clinicians and athletic trainers in making difficult return to play decisions
- Provides reliable baseline test information
- Produces comprehensive report of test results
- Results can be e-mailed or faxed for fast consultation by a neuropsychologist
- Automatically stores data from repeat testing
- Testing is administered online for individuals or groups
The test battery consists of a near infinite number of alternate forms by randomly varying the stimulus array for each administration. This feature was built in to the program to minimize the practice effects that have limited the usefulness of more traditional neurocognitive tests. ImPACT takes approximately 20 minutes to complete. The program measures multiple aspects of cognitive functioning in athletes including:
- Attention span
- Sustained and selective attention time
- Non verbal problem solving
- Working memory
- Response variability
- Reaction time
