Abstract

Computerized neurocognitive tests (CNT) are quick objective assessments used to assess an individual’s recovery from a concussion. However, CNT are not presently used during a pitch-side diagnosis of a concussion. Instead, paper-and-pencil assessments are administered which can lead to a subjective interpretation of a concussion and can vary between clinicians. Thus, this study looked to explore whether a new computerized neurocognitive assessment (RESET) could be used pitch-side to establish a more objective diagnosis. However, in order to do this, the reliability of RESET was firstly explored.

To determine the test-retest reliability of RESET, 44 University students completed a baseline neurocognitive assessment, and further tests 45 and 50 days after. Whilst to assess the effect of fatigue and therefore RESET’s potential to be used pitch-side, a shortened RESET battery was administered to 24 University Students whom completed a the RESET battery at baseline before once again completing three further RESET assessments under the influence of fatigue.

Between baseline and day 45, RESET’s reliability ranged from 0.64 to 0.78 resembling good to strong reliability and ranged from 0.47 to 0.88 between day 45 and 50 displaying moderate to strong reliability. Whilst the analysis of the exercise-induced fatigue study found that compared to baseline, neurocognitive performance post-fatigue significantly increased in three out of the six assessments administered.

The test-retest reliability of RESET over a 45 day interval was higher than previous reliability values on other computerized neurocognitive tests, currently used to assess concussion. Further, due to no assessments being negatively influenced by fatigue, it is plausible that RESET could be an effective test administered pitch-side. However, it is essential that more assessments are conducted on the reliability and also the sensitivity of RESET before it can be definitively used to assess concussion.
