Abstract
Objectives
To 1) determine the association between computerized and functional reaction time,
and 2) compare functional reaction times between female athletes with and without
a concussion history.
Design
Cross-sectional study.
Methods
Twenty female college athletes with concussion history (age = 19.1 ± 1.5 years, height = 166.9 ± 6.7 cm,
mass = 62.8 ± 6.9 kg, median total concussion = 1.0 [interquartile range = 1.0, 2.0]),
and 28 female college athletes without concussion history (age = 19.1 ± 1.0 years,
height = 172.7 ± 8.3 cm, mass = 65.4 ± 8.4 kg). Functional reaction time was assessed
during jump landing and dominant and non-dominant limb cutting. Computerized assessments
included simple, complex, Stroop, and composite reaction times. Partial correlations
investigated the associations between functional and computerized reaction time assessments
while covarying for time between computerized and functional reaction time assessments.
Analysis of covariance compared functional and computerized reaction time, covarying
for time since concussion.
Results
There were no significant correlations between functional and computerized reaction
time assessments (p-range = 0.318 to 0.999, partial correlation range = −0.149 to 0.072). Reaction time did not differ between groups during any functional
(p-range = 0.057 to 0.920) or computerized (p-range = 0.605 to 0.860) reaction time
assessments.
Conclusions
Post-concussion reaction time is commonly assessed via computerized measures, but
our data suggest computerized reaction time assessments are not characterizing reaction
time during sport-like movements in varsity-level female athletes. Future research
should investigate confounding factors of functional reaction time.
