A Reliability Study conducted from August 2021 through January 2023* found 91% of concussed individuals correctly identified as having a concussion by the HitCheck Cognitive Testing battery.
The same study found that 100% of non-concussed individuals were correctly identified.
91% of all concussed individuals were correctly identified as having a concussion.
100% of non-concussed individuals were correctly identified as NOT having a concussion.
* 242 high school football players participated in three states. 83 subjects completed post-injury tests and were evaluated by medical professionals. 49 subjects were diagnosed with concussion. 34 subjects were diagnosed with no concussion.
Through Test/Retest Reliability, Non-Inferiority Testing, and Comparative Analysis it was determined that HitCheck, SCAT and ImPACT instruments possess convergent validity.
The correlations between the HitCheck and SCAT instruments were not significantly different.
Z = 0.040
The correlations between the HitCheck and ImPACT instruments were not significantly different
Z = 0.231
