Objective Our previous work has consistently shown a decline in cognitive-motor integration (CMI) in those with a history of concussion, those with less sport experience, and older individuals. Here we characterize CMI performance of individuals as a function of these factors. Based on rodent models, we hypothesized that those with multiple concuss...

Objective Develop an on-field cognitive-motor integration task for assessing post-concussion return readiness. Hypothesis: athletes without a history (Hx) of concussion perform faster and incur fewer errors in the different task conditions versus athletes with a Hx. Design Prospective study. Setting Canadian university. Participants 180 asymptom...

Introduction Fifteen percent of individuals who sustain a concussion develop persistent concussion symptoms (PCS). Recent literature has demonstrated atrophy of the frontal, parietal, and cerebellar regions following acute concussive injury. The frontoparietal-cerebellar network is essential for the performance of visuomotor transformation tasks re...

Fifteen percent of individuals who sustain a concussion go on to develop post-concussion syndrome (PCS). These persistent symptoms are believed to be due to damage to white matter tracts and impaired neurotransmission. Specifically, declines in white matter integrity following concussion have been found along the long-coursing axons underlying the...

Objective To investigate the use of the Sport Concussion Assessment Tool 3 (SCAT3) as an assessment tool in the varsity population, as well as the effects of sex and concussion history on both baseline and postconcussion scores. Methods A comparison between baseline and postconcussion SCAT3 scores of varsity level athletes was conducted through re...

Objective Cognitive-motor integration (CMI) is required in sport when performing movements where a rule is used to align the required motor output and the guiding visual information. Previous research has shown CMI declines in young athletes with a concussion history, deemed recovered at the time of evaluation. The purpose of this study was to char...

Objective There is a higher risk of re-injury for athletes with concussion history when returning to play, despite being asymptomatic and cleared for activity. One possible explanation is that current return to play assessments test thinking and moving separately, but sport activities often require their concurrent processing (cognitive-motor integ...

Aim To observe the effects of concussion history on cognitive-motor integration in elite-level athletes. Methods The study included 102 National Hockey League draft prospects (n = 51 concussion history [CH]; n = 51 no history [NC]). Participants completed two computer-based visuomotor tasks, one involved ‘standard’ visuomotor mapping and one invol...

Context There is a lack of research on sex differences for severe injuries across a variety of sports at the collegiate level. Objective To compare differences in injury severity and concussion between sexes and collegiate sports. Design Descriptive epidemiological study. Participants 1,657 injuries were analyzed from collegiate teams at York Un...

Objective: To determine the infl uence of concussion on cognitive performance while completing concurrent sport-specifi c tasks to further inform return-to-play protocols for youth athletes. Design: This descriptive case pilot study compared the performance of youth ice hockey players who had experienced a concussion in the last ice hockey season t...
