OBJECTIVE: To determine if baseline Sport Concussion Assessment Tool, third Edition (SCAT3) scores differ between athletes with and without disability. DESIGN: Cross-sectional comparison of preseason baseline SCAT3 scores for a range of England international footballers. SETTING: Team doctors and physiotherapists supporting England football teams recorded players' SCAT 3 baseline tests from August 1, 2013 to July 31, 2014. PARTICIPANTS: A convenience sample of 249 England footballers, of whom 185 were players without disability (male: 119; female: 66) and 64 were players with disability (male learning disability: 17; male cerebral palsy: 28; male blind: 10; female deaf: 9)...

The aim of this study was to evaluate longitudinal changes in the diffusion characteristics of brain white matter (WM) in collegiate athletes at three time points: prior to the start of the football season (T1), after one season of football (T2), followed by six months of no-contact rest (T3). Fifteen male collegiate football players and 5 male non-athlete student controls underwent diffusion MR imaging and computerized cognitive testing at all three timepoints. Whole-brain tract-based spatial statistics (TBSS) were used to compare fractional anisotropy (FA), radial diffusivity (RD), axial diffusivity (AD), and trace between all timepoints...

CONTEXT:  Neurocognitive test scores are often considered an important aspect of concussion management. To best use these data, clinicians must understand potential factors that may influence baseline performance on these tests. OBJECTIVE:  To determine preexisting factors that may influence performance on the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT). DESIGN:  Cross-sectional study. SETTING:  Research laboratory...

OBJECTIVE: To determine whether tau changes after sport-related concussion (SRC) relate to return to play (RTP). METHODS: Collegiate athletes underwent preseason plasma sampling and cognitive testing and were followed. After a SRC (n = 46), athletes and controls (n = 37) had sampling at 6 hours, and at 24 hours, 72 hours, and 7 days after SRC. A sample of 21 nonathlete controls were compared at baseline. SRC athletes were grouped by long (>10 days, n = 23) and short (≤10 days, n = 18) RTP...

The Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) is a computerized neuropsychological test battery commonly used to assess cognitive functioning after a concussion. It is recommended that application of ImPACT utilizes a baseline administration so athletes have an individualized baseline with which to compare post-injury results should they sustain a concussion. It has been suggested that athletes may provide suboptimal effort, called "sandbagging," in order to return to their baseline cognitive scores, and thus to play, more quickly...

BACKGROUND: Negative emotional states resulting from concussion are of increasing concern. In the current study, we developed a model to investigate negative affect following concussion in the projectile concussive injury (PCI) model. High frequency ultrasonic vocalizations (22kHz USVs) are associated with negative affective stimuli in rats. Changes in negative affective state were examined following PCI using a mild air-puff stimulus to elicit 22kHz USVs. NEW METHOD: Forty-eight hours post-injury animals were placed into a clean acrylic box lined with bedding...

BACKGROUND: Research on the acute effects of a concussion among lacrosse players is limited, and postconcussion patterns between male and female athletes have yet to be clearly established. Differences in the style of play and protective gear worn among male and female lacrosse players potentially confound a direct comparison of sex-based differences in this population. PURPOSE: To explore sex-based differences in postconcussive neurocognitive functioning and symptom reporting outcomes in concussed adolescent male and female lacrosse players compared with a group of soccer players...

CONTEXT:  Computerized neurocognitive assessments are commonly used to manage sport-related concussion. Variations in baseline performance may influence neurocognitive performance after injury as well as the amount of time needed for an athlete to be cleared for return to sport participation. OBJECTIVE:  To investigate the relationship between mean baseline Immediate Post-Concussion Assessment and Cognitive Test (ImPACT) scores and postconcussion reliable decline as well as the association between postconcussion cognitive decline and days missed after injury...

CONTEXT: After a concussion, guidelines emphasize that an athlete should be asymptomatic before starting a return-to-play protocol. However, many concussion symptoms are nonspecific and may be present in individuals without concussion. Limited evidence exists regarding the presence of "typical" or preinjury (baseline) symptoms in child and youth athletes. OBJECTIVE: To describe the frequency of symptoms reported at baseline by child and youth athletes and identify how age, sex, history of concussion, and learning factors influence the presence of baseline symptoms...

BACKGROUND: Effective interventions are needed for individuals with persisting post-concussion symptoms. High-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM®) is an allostatic, closed-loop, acoustic stimulation neurotechnology, designed to facilitate relaxation and self-optimization of neural oscillations. METHODS: Fifteen athletes (seven females, mean age 18.1 years, SD 2.6) with persisting post-concussion symptoms received 18.7 (SD 6...

OBJECTIVES: Baseline and post-concussion neurocognitive testing is useful in managing concussed athletes. Attention deficit hyperactivity disorder (ADHD) and stimulant medications are recognized as potential modifiers of performance on neurocognitive testing by the Concussion in Sport Group. Our goal was to assess whether individuals with ADHD perform differently on post-concussion testing and if this difference is related to the use of stimulants. METHODS: Retrospective case-control study in which 4373 athletes underwent baseline and post-concussion testing using the ImPACT battery...

BACKGROUND: KINARM end point robotic testing on a range of tasks evaluating sensory, motor and cognitive function in children/adolescents with no neurologic impairment has been shown to be reliable. The objective of this study was to determine whether differences in baseline performance on multiple robotic tasks could be identified between pediatric/adolescent ice hockey players (age range 10-14) with and without a history of concussion. METHODS: Three hundred and eighty-five pediatric/adolescent ice hockey players (ages 10-14) completed robotic testing (94 with and 292 without a history of concussion)...

OBJECTIVE: Computerized neuropsychological assessment of concussion has rapidly expanded and Immediate Post-Concussion and Cognitive Testing (ImPACT) is among the most commonly used measures in this domain. ImPACT was primarily developed for use with athletic populations but continues to expand beyond athletics to settings such as the workplace and schools where motivational dispositions may vary. The purpose of the present study was to conduct a systematic review of existing research investigating the prevalence of invalid baseline results and the effectiveness of ImPACT's embedded invalidity indicators in detecting suspect effort...

BACKGROUND AND OBJECTIVES: Postconcussive and co-occurring psychological symptoms are not uncommon after sports-related concussion and are associated with functional impairment and societal costs. There is no evidence-based treatment targeting postconcussive symptoms in children and adolescents. The goal of this study was to test a collaborative care intervention model with embedded cognitive-behavioral therapy, care management, and psychopharmacological consultation. We hypothesized that patients in collaborative care would demonstrate greater reductions in postconcussive, depressive, and anxiety symptoms and improvement in functioning over the course of 6 months, compared with usual care control...
