Sport-related concussion (SRC) is a growing health concern, particularly in younger, at-risk athletic populations. These injuries commonly present with a wide range of clinical signs (i.e., poor coordination, behavioral, mood changes) and symptoms (i.e., headache, dizziness, difficulty concentrating), along with neurocognitive and vestibular/ocular impairments. This review of SRCs in youth athletes focuses on individuals 5–18 years of age and includes an overview of concussion (i.e., definition, signs/symptoms, epidemiology), as well as concussion education and awareness. This is followed by a review of SRC assessment and management strategies, along with common recovery, return-to-play, and treatment approaches. Finally, suggestions are made for future research and recommendations pertaining to SRC in youth athletes.

Recent evidence suggests previously concussed athletes are at greater risk for lower-extremity (LE) injuries than are controls. However, little is known regarding the influence of sports-related concussion (SRC) on landing biomechanics that may provide a mechanistic rationale for LE injury risk. The purpose of this investigation was to examine LE drop-landing biomechanics in adolescent athletes with and without a previous SRC history. Participants included 10 adolescent athletes with an SRC history and 11 controls from multiple sports. Three-dimensional kinematic and kinetic data associated with LE injury risk were analyzed across 5 trials for 30- and 60-cm landing heights. Multivariate analyses indicated group differences in landing patterns from the 30- (P = .041) and 60-cm (P = .015) landing heights. Follow-up analyses indicated that concussed adolescent athletes demonstrated significantly less ankle dorsiflexion and knee flexion versus controls when performing drop landings. Our findings suggest that previously concussed adolescent athletes complete drop-landing maneuvers with ankle and knee joint kinematic patterns that suggest greater risk for LE injury. While limitations such as sport variety and explicit LE injury history are present, the results of this study provide a possible biomechanical rationale for the association between SRC and LE injury risk.

The present study explored the relationship of neurocognitive performance and symptoms to coping responses at 3 and 8 days postconcussion. A total of 104 concussed athletes (M = 16.41, SD = 2.19 years) completed the Immediate Post Concussion Assessment Cognitive Testing (ImPACT) at baseline and the ImPACT and Brief Cope inventory at 3 and 8 days postconcussion. Concussed athletes reported more frequent use of selfdistraction, behavioral disengagement, religion, and self-blame 3 days postconcussion compared with 8 days. Concussed athletes reported more use of avoidance coping at 3 days than 8 days (Wilks’s Lambda =.95, F [1, 100] =4.71, p = .032, η²=.046) post-injury. Total symptoms were also a significant (p = .001) predictor of avoidance coping 3 days postconcussion and decreased visual memory was associated with increased avoidance coping (p = .03) 8 days post-injury. Time since injury likely impacts neurocognitive performance, symptomology, and coping. Clinicians should be aware of higher reported symptoms early and lingering visual memory deficits 1-week post-injury.

Context: The utility of baseline vestibular and ocular motor screening (VOMS) in high school and collegiate athletes is demonstrated throughout the literature; however, baseline VOMS data at the youth level are limited. In addition, with the recent adoption of the change scoring method, there is a need to document baseline VOMS total and change scores in a pediatric population. Objective: To document baseline VOMS total and change scores and to document the internal consistency of the VOMS in pediatric soccer athletes. We hypothesized that the VOMS would demonstrate strong internal consistency in pediatric soccer athletes. Design: Cross-sectional study. Methods: Pediatric soccer athletes (N = 110; range = 5–12 y) completed the VOMS at baseline. Descriptive statistics summarized demographic information, VOMS total scores, and VOMS change scores. Cronbach α assessed internal consistency for VOMS total scores and change scores. Results: Twenty-one (19.1%) participants had at least one total score above clinical cutoffs (≥2 on any VOMS component and ≥5 cm on average near point convergence). Forty (36.4%) participants had at least one change score above clinical cutoffs (≥1 on any VOMS component and ≥3 cm on average near point convergence). The internal consistency was strong for total scores with all VOMS components included (Cronbach α = .80) and change scores (Cronbach α = .89). Conclusions: Although results suggest VOMS items measure distinct components of the vestibular and ocular motor systems, caution should be taken when interpreting VOMS total and change scores in pediatric athletes, as overreporting symptoms is common, thereby impacting the false-positive rate.

Context: Knee self-efficacy and injury-related fear are associated with poor self-reported knee function and decreased physical activity (PA) after ACL reconstruction (ACLR). Limited research has explored contextual factors that may influence psychological responses in this population, such as history of sport-related concussion (SRC). After SRC, individuals may experience increased negative emotions, such as sadness and nervousness. However, it is unknown how SRC history may influence knee-self efficacy and injury-related fear in individuals with ACLR. The purpose of this study was to compare knee self-efficacy and injury-related fear in individuals after ACLR who present with and without history of SRC. Design: Cross-sectional study. Methods: Forty participants ≥1 year postunilateral ACLR were separated by history of SRC (no SRC = 29, SRC = 11). The Knee Self-Efficacy Scale (KSES) and subscales measured certainty regarding performance of daily activities (KSES-ADL), sports/leisure activities (KSES-Sport), physical activities (KSES-PA), and future knee function (KSES-Future). The Tampa Scale of Kinesiophobia-11 measured injury-related fear. Mann–Whitney U tests were used to examine between-group differences. Hedges g effect sizes and 95% confidence interval were used to examine clinically meaningful group differences. Results: Individuals with a history of ACLR and SRC demonstrated worse KSES-PA (7.5 [5.3]) compared with those without a history of SRC (8.1 [6.1], P = .03). No other statistically significant differences were observed. A medium effect size was present for the KSES-PA (0.62), KSES-ADL (0.42), KSES-Present (ADL + PA + Sport) (0.48), KSES-Total (0.53), and Tampa Scale of Kinesiophobia-11 (0.61) but must be interpreted with caution as 95% confidence interval crossed 0. Conclusions: This exploratory study indicated that individuals with a history of ACLR and SRC had worse knee self-efficacy for PA compared with those without history of SRC. Rehabilitation specialists should monitor knee self-efficacy deficits in the post-ACLR population and recognize the potential influence of cumulative injury history on rehabilitative outcomes.
