Since the late nineties, computerized neurocognitive testing has become a central component of sport-related concussion (SRC) management at all levels of sport. In 2005, a review of the available evidence on the psychometric properties of four computerized neuropsychological test batteries concluded that the tests did not possess the necessary crit...

The ImPACT (Immediate Postconcussion Assessment and Cognitive Testing) is a computerized neurocognitive test used to assist in the management of sport concussion management. A number of studies have documented the reliability and sensitivity of the ImPACT, but no studies have examined the equivalence of the ImPACT's alternate forms. The objective o...

Context: Computerized neuropsychological testing is commonly used in the assessment and management of sport-related concussion. Even though computerized testing is widespread, psychometric evidence for test-retest reliability is somewhat limited.
