Objective: The purpose of our study was to investigate if a significant change in concussion baseline measurements occur in athletes who did not reportedly sustain a concussion.

Design: Cohort Study

Setting: Division I University

Participants 22 Division I Men’s Lacrosse players’ data were used for the BESS test (age=19.95, ± 0.99) and 26 Division I Men’s Lacrosse players’ data were used for the CNS Vital Signs test (age=20.15, ± 1.05)

Interventions: calendar year; 2015 competitive lacrosse season

Outcome measures: Repeated-measures ANOVAs and paired samples t-tests determined the change in concussion baseline measurement scores from pre-season 2015, post-season 2015, and pre-season 2016. BESS scores and the ten tests associated with CNS Vital Signs were analysed for changes.

Main results: There were increases in the number of errors committed during the foam double leg stance (p=0.017) and foam tandem stance (p=0.007) from pre-season 2015 to pre-season 2016. 60% of of the tests within the CNS Vital Signs testing battery resulted in significant improvements from pre-season 2015 to pre-season 2016: psychomotor speed (p=0.031), executive function (p=0.003), cognitive flexibility (p=0.004), reaction time (p=0.004), simple reaction time (p=0.002), and shifting attention correct reaction time (p=0.016).

Conclusions: Concussion baseline measurements should be repeated on an annual basis to improve accuracy when implementing a return-to-play protocol following a concussion.
