Longitudinal neurocognitive trajectories and risk factors in the first three months following pediatric concussion. Brain Inj 2024; 38:764-772. [PMID: 38704842 DOI: 10.1080/02699052.2024.2347553] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2023] [Accepted: 04/22/2024] [Indexed: 05/07/2024]
Abstract
OBJECTIVE To identify differential trajectories of neurocognitive outcomes following pediatric concussion and investigate predictors associated with patterns of recovery up to 3 months. METHODS 74 participants aged 8-17 years completed attention/working memory, processing speed, and executive function measures at 2 weeks, 1 month, and 3 months post-injury. We used principal component analysis to generate a composite of information processing. Group-based trajectory modeling identified latent trajectories. Multinominal logistic regression was used to examine associations between risk factors and trajectory groups. RESULTS We identified three trajectories of neurocognitive outcomes. The medium (54.6%) and high improving groups (35.8%) showed ongoing increase in information processing, while the low persistent group showed limited change 3 months post-injury. This group recorded below average scores on Digit Span Forward and Backward at 3 months. History of pre-injury headache was significantly associated with the persistent low scoring group, relative to the medium improving (p = 0.03) but not the high improving group (p = 0.09). CONCLUSIONS This study indicates variability in neurocognitive outcomes according to three differential trajectories, with groups partially distinguished by preexisting child factors (history of frequent headaches). Modelling that accounts for heterogeneity in individual outcomes is essential to identify clinically meaningful indices that are indicative of children requiring intervention.

Abstract
BACKGROUND Accurate concussion monitoring requires access to preinjury baseline data. This is particularly important in adolescent athletes who have a high risk of concussion and are prone to prolonged recovery. As Rugby Union is governed by similar laws for men and women, it is also an ideal population to rigorously examine the impact of biological sex on concussion symptoms. AIMS To evaluate self-reported concussion symptoms at baseline in adolescent rugby union players, and examine if subtype-specific symptoms are affected by concussion history and biological sex. METHODS Adolescent rugby union players aged 16-18 years were recruited during the 2022-2023 playing season. Participants completed a series of questionnaires covering post-concussion symptoms, concussion clinical profiles, anxiety, depression and fear avoidance behaviours. Independent variables of interest in analysis were biological sex and concussion history. RESULTS 149 participants (75% male) were included. 42% (63/149) reported at least one previous concussion (average time since concussion: 18.7 months, range 1-72). Adolescents with a concussion history reported significantly higher scores than those with no history, across two clinical profiles (ocular and sleep), concussion symptom severity, and depression, all based on medium effect sizes (SMD 0.3-0.5). Females had significantly higher scores across cognitive/fatigue, ocular and sleep clinical profiles, concussion symptoms, anxiety and depression, each with large effect sizes (SMD > 0.5). CONCLUSIONS Concussion history and sex are associated with higher baseline scores on specific concussion clinical profile, concussion symptom severity, and anxiety symptoms. These findings highlight the importance of considering baseline differences when interpreting post-injury clinical profile symptoms in adolescent rugby players.

Abstract
OBJECTIVE Cervical spine proprioception may be impaired after concussion. Our objective was to determine the diagnostic utility of cervical spine proprioception for adolescent concussion. DESIGN Cross-sectional. SETTING Research laboratory. PARTICIPANTS Adolescents ≤18 days of concussion and uninjured controls. INTERVENTIONS N/A. MAIN OUTCOMES Head repositioning accuracy (HRA) testing, a measure of cervical spine proprioception. The HRA test involved patients relocating their head back to a neutral starting position with eyes closed after maximal cervical spine flexion, extension, and right and left rotations. The overall HRA error score was the mean error (distance from the starting point to self-reported return to neutral) across 12 trials: 3 trials in each direction. We used t-tests to compare group means and logistic regression (outcome = group, predictor = HRA, covariates) to calculate odds ratios. We used a receiver operator characteristic curve to evaluate area under the curve (AUC) and calculate the optimal HRA cutpoint to distinguish concussion from controls. RESULTS We enrolled and tested 46 participants with concussion (age = 15.8 ± 1.3 years, 59% female, mean = 11.3 ± 3.3 days postconcussion) and 83 uninjured controls (age = 16.1 ± 1.4 years, 88% female). The concussion group had significantly worse HRA than controls (4.3 ± 1.6 vs 2.9 ± 0.7 degrees, P < 0.001, Cohen d = 1.19). The univariable HRA model AUC was 0.81 (95% CI = 0.73, 0.90). After adjusting for age, sex, and concussion history, the multivariable model AUC improved to 0.85 (95% CI = 0.77, 0.92). The model correctly classified 80% of participants as concussion/control at a 3.5-degree cutpoint. CONCLUSIONS Adolescents with concussion demonstrated worse cervical spine proprioception than uninjured controls. Head repositioning accuracy may offer diagnostic utility for subacute concussion.

Abstract
Neurovascular coupling (NVC) uniquely describes cerebrovascular response to neural activation and has demonstrated impairments following concussion in adult patients. It is currently unclear how adolescent patients experience impaired NVC acutely following concussion during this dynamic phase of physiological development. The purpose of this study was to investigate NVC in acutely concussed adolescent patients relative to controls. We recruited patients presenting to a sports medicine practice within 28 days of a concussion or a musculoskeletal injury (controls). Transcranial Doppler ultrasound was used to measure changes in patients' posterior cerebral artery (PCA) velocity in response to two progressively challenging visual tasks: (1) reading and (2) visual search. Each task was presented in five 1-min trials (20 sec eyes closed/40 sec eyes open). Resting PCA velocity data were derived by averaging PCA velocity across a 2-min baseline period that preceded the visual tasks. Filtered task data were converted to time-series curves representing 40 consecutive 1-sec averages for each trial. Curves were then averaged across the five trials and time-aligned to stimulus onset (eyes open) to generate a single ensemble-averaged 40-sec curve representing NVC response for each participant for each task. Independent t tests were used to assess group differences (concussion vs. control) in resting PCA velocity. Separate linear mixed-effects models were used to evaluate group differences (concussion vs. control) in NVC response profiles for both visual tasks and group-by-task interaction. Twenty-one concussion patients (female = 8 [38.1%]; age = 14.4 ± 1.9 years) and 20 controls (female = 7 [35.0%]; age = 14.4 ± 1.9 years) were included in our analysis. Average resting PCA velocity did not significantly differ between concussion patients (36.6 ± 8.0 cm/sec) and controls (39.3 ± 8.5 cm/sec) (t39 = 1.06; p = 0.30). There were no significant group differences in relative NVC response curves during the reading task (F1,1560 = 2.23; p = 0.14) or the visual search task (F1,1521 = 2.04; p = 0.15). In contrast, the differential response to task (e.g., increase from reading task to visual search task) was significantly greater in concussion patients than in controls (p < 0.0001). The NVC response to the visual search task was 7.1% higher than the response to reading in concussion patients relative to being 5.5% higher in controls. Our data indicate that concussed patients present with a significantly greater response to more difficult tasks than do controls, suggesting that concussed adolescents require increased neural resource allocation as task difficulty increases. The study provides insight into the neurophysiological consequences of concussion in adolescent patients.

Abstract
Some children and adolescents have persistent concussion symptoms that extend beyond the typical 3-4 week recovery window. Our understanding about what to expect when recovery is atypical, particularly in elementary-age children, is incomplete because there are very few targeted studies of this age group in the published literature. Aims were to identify lingering symptoms that present at three months post-concussion and to determine what factors are associated with prolonged recovery in an elementary-age group. Participants were 123 children aged 5-10 years who were seen at specialized concussion clinics, divided into expected and late recovery groups. Parents rated concussion symptoms on a scale from the Sideline Concussion Assessment Tool-5 (SCAT-5). The most frequent symptoms were headache, irritability, feeling more emotional, and sensitivity to noise. Stepwise logistic regression determined that female sex and total symptom burden at initial visit, but not any specific symptom, predicted prolonged recovery. Clinicians are advised to carefully monitor children who report numerous symptoms after concussion, particularly when the concussed children are girls.

Abstract
One in five adolescents will sustain a concussion in their lifetime. A concussion may result in symptoms that affect an adolescent's ability to attend school and engage in learning tasks. This study was guided by interpretivism. We conducted one-on-one semi-structured interviews to explore the perspectives of 20 adolescents (ages 14-18) returning to school after a concussion. Interviews were coded inductively and analyzed using reflexive thematic analysis. Five interconnected themes emerged with returning to school and accessing school supports: (1) concussion symptoms affected adolescents' schoolwork; (2) access to academic accommodations eased adolescents' return to school; (3) having supportive and understanding friends, family, and teachers facilitated adolescents' return to school; (4) communication amongst school stakeholders was desired, but often lacking; and (5) feeling anxious, frustrated, and sad with the return to school process. Adolescents' experiences were multifaceted and many factors contributed to their return to school experiences. Our findings can inform our understanding of the experiences of adolescents returning to school following concussion and can inform the development of concussion management supports at schools.

Abstract
OBJECTIVE To investigate characteristics of sport-related concussion (SRC), recreation-related concussion (RRC), and nonsport or recreation-related concussion (non-SRRC) in patients 5 through 12 years old, an understudied population in youth concussion. STUDY DESIGN This observational study included patients aged 5 through 12 years presenting to a specialty care concussion setting at ≤28 days postinjury from 2018 through 2022. The following characteristics were assessed: demographics, injury mechanism (SRC, RRC, or SRRC), point of healthcare entry, and clinical signs and symptoms. Kruskal-Wallis and chi-square tests were used to assess group differences. Posthoc pairwise comparisons were employed for all analyses (α = 0.017). RESULTS One thousand one hundred forty-one patients reported at ≤28 days of injury (female = 42.9%, median age = 11, interquartile range (IQR) = 9-12) with the most common mechanism being RRC (37.3%), followed by non-SRRC (31.9%). More non-SRRCs (39.6%) and RRC (35.7%) were first seen in the emergency department (P < .001) compared with SRC (27.9%). Patients with RRC and non-SRRC were first evaluated at specialists 2 and 3 days later than SRC (P < .001). Patients with non-SRRC reported with higher symptom burden, more frequent visio-vestibular abnormalities, and more changes to sleep and daily habits (P < .001) compared with RRC and SRC (P < .001). CONCLUSIONS In concussion patients 5 through 12 years, RRCs and non-SRRC were more prevalent than SRC, presenting first more commonly to the emergency department and taking longer to present to specialists. Non-SRRC had more severe clinical features. RRC and non-SRRC are distinct from SRC in potential for less supervision at time of injury and less direct access to established concussion health care following injury.

Abstract
BACKGROUND Aerobic exercise facilitates postconcussion symptom resolution at the group level, but patient-level characteristics may affect the likelihood of treatment efficacy. PURPOSE This study aimed to investigate demographic and clinical characteristics, which differentiate postconcussion aerobic exercise treatment efficacy from nonefficacy in the intervention arm of a randomized clinical trial. METHODS Adolescent and young adult participants initiated a standardized aerobic exercise intervention within 14 d of concussion, consisting of self-selected exercise for 100 min·wk -1 at an individualized heart rate (80% of heart rate induced symptom exacerbation during graded exercise testing). Treatment efficacy was defined as symptom resolution within 28-d postconcussion. Treatment efficacy and nonefficacy groups were compared on demographics, clinical characteristics, intervention adherence, and persistent symptom risk using the Predicting Persistent Postconcussive Problems in Pediatrics (5P) clinical risk score. RESULTS A total of 27 participants (16.1 ± 2.3 yr old; range, 11-21 yr; 52% female) began the intervention, with a mean of 9.5 ± 3.7 d after concussion; half ( n = 13; 48%) demonstrated treatment efficacy (symptom resolution within 28 d postconcussion). Those whose symptoms resolved within 28 d had significantly lower preintervention postconcussion symptom inventory scores (21.2 ± 13.2 vs 41.4 ± 22.2; P < 0.01), greater adherence to the intervention (77% vs 36%; P = 0.05), and longer average exercise duration (median [interquartile range], 49.7 [36.8-68.6] vs 30.4 [20.7-34.7] min; P < 0.01) than those whose symptoms lasted more than 28 d. Groups were similar in age, sex, timing of intervention, and preintervention 5P risk score. CONCLUSIONS A standardized aerobic exercise intervention initiated within 14 d of concussion demonstrated efficacy for approximately half of participants, according to our definition of treatment efficacy. This multisite aerobic exercise intervention suggests that lower symptom severity, higher intervention adherence, and greater exercise duration are factors that increase the likelihood of symptoms resolving within 28 d of concussion.

Abstract
PURPOSE This study aimed to examine how moderate-to-vigorous physical activity (MVPA) during concussion recovery influences self-reported anxiety symptoms at follow-up assessment. We hypothesized that more MVPA after concussion would be associated with lower anxiety rating at follow-up. METHODS We performed a prospective study of participants aged 13-18 yr initially assessed within 14 d of diagnosed concussion. Participants rated concussion symptoms using the Post-Concussion Symptom Inventory and were provided a wrist-worn actigraphy device to track activity for 1 wk after assessment. At follow-up assessment, participants rated anxiety symptoms using the four-question Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety subscale. Each question ranged from 1 (never) to 5 (almost always), with an overall score range of 4-20. For univariable analysis, we calculated correlation coefficients between MVPA and PROMIS anxiety subscale scores. We then created a multiple linear regression model with follow-up PROMIS anxiety subscale score as the outcome and MVPA, sex, initial symptom severity, and preconcussion anxiety as predictors. RESULTS We enrolled and initially tested 55 participants, and 48 were included in the final analysis (age, 14.6±2.7 yr; 56% female; initial assessment, 7.3± 3.1 d; follow-up assessment, 42.0±29.7 d). We observed an inverse and low correlation between MVPA and follow-up PROMIS anxiety subscale T-scores ( r = -0.30, P = 0.04). Multivariable regression results indicated that MVPA ( β = -5.30; 95% confidence interval (CI), -10.58 to -0.01), initial Post-Concussion Symptom Inventory score ( β = 0.11; 95% CI, 0.03 to 0.19), and preconcussion anxiety ( β = 5.56; 95% CI, 0.12 to 11.0), but not sex ( β = -2.60; 95% CI, -7.14, to 1.94), were associated with follow-up PROMIS anxiety subscale T-scores. CONCLUSIONS After adjusting for covariates, more MVPA early after concussion predicted lower PROMIS anxiety subscale scores at follow-up. Although initial concussion symptom severity and preconcussion anxiety were also associated with follow-up PROMIS anxiety subscale score, MVPA represents a modifiable factor that may contribute to lower anxiety symptoms.

Abstract
Of the four million children who experience a concussion each year, 30-50% of children will experience delayed recovery, where they will continue to experience symptoms more than two weeks after their injury. Delayed recovery from concussion encompasses emotional, behavioral, physical, and cognitive symptoms, and as such, there is an increased focus on developing an objective tool to determine risk of delayed recovery. This study aimed to identify a blood protein signature predictive of delayed recovery from concussion in children. Plasma samples were collected from children who presented to the Emergency Department at the Royal Children's Hospital, Melbourne, within 48h post-concussion. This study involved a discovery and validation phase. For the discovery phase, untargeted proteomics analysis was performed using single window acquisition of all theoretical mass spectra to identify blood proteins differentially abundant in samples from children with and without delayed recovery from concussion. A subset of these proteins was then validated in a separate participant cohort using multiple reaction monitoring and enzyme linked immunosorbent assay. A blood protein signature predictive of delayed recovery from concussion was modeled using a Support Vector Machine, a machine learning approach. In the discovery phase, 22 blood proteins were differentially abundant in age- and sex-matched samples from children with (n = 9) and without (n = 9) delayed recovery from concussion, six of whom were chosen for validation. In the validation phase, alpha-1-ACT was shown to be significantly lower in children with delayed recovery (n = 12) compared with those without delayed recovery (n = 28), those with orthopedic injuries (n = 7) and healthy controls (n = 33). A model consisting of alpha-1-ACT concentration stratified children based on recovery from concussion with an 0.88 area under the curve. We have identified that alpha-1-ACT differentiates between children at risk of delayed recovery from those without delayed recovery from concussion. To our knowledge, this is the first study to identify alpha-1-ACT as a potential marker of delayed recovery from concussion in children. Multi-site studies are required to further validate this finding before use in a clinical setting.

Abstract
Concussion often results in psychological symptoms, including anxiety. Post-concussion anxiety has been well documented, although much of this research has focused on collegiate athletes. The purpose of this study was to compare (1) anxiety symptoms in concussed and healthy controls over time and (2) to explore sex differences in post-concussion anxiety within the context of pubertal development. Participants (N = 126, mean age = 15.1 years old), including concussed (n = 86) and healthy adolescents (n = 40), completed the Pubertal Development Scale (PDS) and the Screen for Child Anxiety and Related Disorders (SCARED-C). The concussed groups completed SCARED-C at three visits (<10 days, 4 weeks, 3 months). Results of an analysis of covariance (ANCOVA) and multi-variate analysis of covariance (MANCOVA) found concussed adolescents reported higher SCARED-C total, generalized, and panic anxiety scores than healthy controls, after controlling for sex, age, and PDS score (PDSS). A three-way mixed ANCOVA examined the effects of sex, PDSS, time, and their interaction on SCARED-C total score in concussed adolescents while controlling for age. There was a significant three-way interaction between sex, age, and PDSS on SCARED-C total score while controlling for age. Overall, we observed increased anxiety in concussed adolescents, compared with controls, as well as greater post-concussion anxiety reported by females compared with males, including within PDSS groups. Concussion providers should be prepared to receive training to administer well-validated measures of psychopathology and should consider that female adolescents, compared with males, regardless of pubertal development, may be at greater risk for post-concussion anxiety.

Abstract
Purpose: Physical education (PE) teachers play an important role in concussion recognition and management in schools both in an academic and activity based setting. This study aimed to identify Irish post-primary PE teachers' concussion knowledge, beliefs, education and management practices. Methods: An anonymous online survey, adapted to the Irish context from the validated BAKPAC-TEACH, was completed by 128 PE teachers (female = 74/123; 60.2%; male = 49/123; 39.8%, 36.1 ± 10.9 years), representing 4% of registered PE teachers in Ireland. Results: PE teachers reported 3.5 ± 4.7 students suffer with a sports-related concussion in their classroom annually and 43.9% previously had a student sustain a concussion during their PE class. Most received concussion education (58.6%), largely provided by sporting bodies. They frequently identified dizziness (93.0%) and headaches (92.2%) as concussion symptoms, but less commonly emotional (more emotional = 36.5%, nervous or anxious = 33.6%, sadness = 28.9%) or sleep (35.2%) symptoms. All PE teachers knew that a concussion requires immediate removal from a game/practice. PE teachers demonstrated less perceived knowledge and confidence relating to academic adjustments and return to learn criteria. Just 31.3% reported their school facilitates academic adjustments. Conclusion: Tailored concussion education addressing knowledge gaps highlighted in this study should be developed. A concussion policy and an academic support team in each school should be established and widely publicised to enhance the support of concussed students in returning to school.

Abstract
BACKGROUND Adolescence represents a window of vulnerability for developing psychological symptoms following concussion, especially in girls. Concussion-related lesions in emotion regulation circuits may help explain these symptoms. However, the contribution of sex and pubertal maturation remains unclear. Using the neurite density index (NDI) in emotion regulation tracts (left/right cingulum bundle [CB], forceps minor [FMIN], and left/right uncinate fasciculus), we sought to elucidate these relationships. METHODS No adolescent had a history of anxiety and/or depression. The Screen for Child Anxiety Related Emotional Disorders and Children's Depression Rating Scale were used at scan to assess anxiety and depressive symptoms in 55 concussed adolescents (41.8% girls) and 50 control adolescents with no current/history of concussion (44% girls). We evaluated if a mediation-moderation model including the NDI (mediation) and sex or pubertal status (moderation) could help explain this relationship. RESULTS Relative to control adolescents, concussed adolescents showed higher anxiety (p = .003) and lower NDI, with those at more advanced pubertal maturation showing greater abnormalities in 4 clusters: the left CB frontal (p = .002), right CB frontal (p = .011), FMIN left-sided (p = .003), and FMIN right-sided (p = .003). Across all concussed adolescents, lower NDI in the left CB frontal and FMIN left-sided clusters partially mediated the association between concussion and anxiety, with the CB being specific to female adolescents. These effects did not explain depressive symptoms. CONCLUSIONS Our findings indicate that lower NDI in the CB and FMIN may help explain anxiety following concussion and that adolescents at more advanced (vs less advanced) status of pubertal maturation may be more vulnerable to concussion-related injuries, especially in girls.

Abstract
OBJECTIVE To establish whether time to exercise cessation using the Buffalo Concussion Treadmill Test (BCTT) protocol can be used as a prognostic indicator of recovery after sport-related mild traumatic brain injury (SR-mTBI). DESIGN Retrospective analysis of prospectively collected data. SETTING Specialist Concussion Clinic. PARTICIPANTS Three hundred and twenty one patients presenting between 2017 and 2019 who underwent BCTT for SR-mTBI. INTERVENTIONS Participants who remained symptomatic at a 2-week follow-up appointment after SR-mTBI underwent BCTT to develop a progressive subsymptom threshold exercise program with fortnightly follow-up until clinical recovery. MAIN OUTCOME MEASURES Clinical recovery was the primary outcome measure. RESULTS A total of 321 participants were eligible to participate in this study (mean age 22.94% and 46% female). The BCTT test duration was divided into 4-minute intervals and those who completed full 20 minutes. There was higher probability of clinical recovery in those who finished the entire 20-minute BCTT protocol compared with those who managed 17-<20 minutes (Hazard Ratio, HR 0.57), 13 to 16 minutes (HR 0.53), 9 to 12 minutes (HR 0.6), 5 to 8 minutes (HR 0.4), and 1 to 4 minutes (HR 0.7), respectively. Those seen earlier after injury ( P = 0.009), male patients ( P = 0.116), younger patients ( P = 0.0003), and those with physiological or cervical dominant ( P = 0.416) symptom clusters were more likely to achieve clinical recovery. Fifty percent of those who completed the full BCTT protocol achieved clinical recovery at day 19 post-injury. CONCLUSIONS The group completing full 20 minutes of BCTT achieved clinical recovery more quickly than those who did not complete full BCTT.

Abstract
Background: The Balance Error Scoring System (BESS) is a commonly used method for clinically evaluating balance after traumatic brain injury. The utilization of force plates, characterized by their cost-effectiveness and portability, facilitates the integration of instrumentation into the BESS protocol. Despite the enhanced precision associated with instrumented measures, there remains a need to determine the clinical significance and feasibility of such measures within pediatric cohorts. Objective: To report a comprehensive set of posturographic measures obtained during instrumented BESS and to examine the concurrent validity, reliability, and feasibility of instrumented BESS in the pediatric point of care setting. Methods: Thirty-seven participants (18 female; aged 13.32 ± 3.31 years) performed BESS while standing on a force plate to simultaneously compute stabilometric measures (instrumented BESS). Ellipse area (EA), path length (PL), and sway velocity (VM) were obtained for each of the six BESS positions and compared with the respective BESS scores. Additionally, the effects of sex and age were explored. A second BESS repetition was performed to evaluate the test-retest reliability. Feedback questionnaires were handed out after testing to evaluate the feasibility of the proposed protocol. Results: The BESS total score was 20.81 ± 6.28. While there was no statistically significant age or sex dependency in the BESS results, instrumented posturography demonstrated an age dependency in EA, VM, and PL. The one-leg stance on a soft surface resulted in the highest BESS score (8.38 ± 1.76), EA (218.78 cm2 ± 168.65), PL (4386.91 mm ± 1859.00), and VM (21.93 mm/s ± 9.29). The Spearman's coefficient displayed moderate to high correlations between the EA (rs = 0.429-0.770, p = 0.001-0.009), PL (rs = 0.451-0.809, p = 0.001-0.006), and VM (rs = 0.451-0.809, p = 0.001-0.006) when compared with the BESS scores for all testing positions, except for the one-leg stance on a soft surface. The BESS total score significantly correlated during the first and second repetition (rs = 0.734, p ≤ 0.001), as did errors during the different testing positions (rs = 0.489-0.799, p ≤ 0.001-0.002), except during the two-legged stance on a soft surface. VM and PL correlated significantly in all testing positions (rs = 0.465-0.675, p ≤ 0.001-0.004; (rs = 0.465-0.675, p ≤ 0.001-0.004), as did EA for all positions except for the two-legged stance on a soft surface (rs = 0.392-0.581, p ≤ 0.001-0.016). A total of 92% of participants stated that the instructions for the testing procedure were very well-explained, while 78% of participants enjoyed the balance testing, and 61% of participants could not decide whether the testing was easy or hard to perform. Conclusions: Instrumented posturography may complement clinical assessment in investigating postural control in children and adolescents. While the BESS score only allows for the consideration of a total score approximating postural control, instrumented posturography offers several parameters representing the responsiveness and magnitude of body sway as well as a more differentiated analysis of movement trajectory. Concise instrumented posturography protocols should be developed to augment neuropediatric assessments in cases where a deficiency in postural control is suspected, potentially stemming from disruptions in the processing of visual, proprioceptive, and/or vestibular information.

BACKGROUND Paediatric acquired brain injury is a life-long condition which impacts on all facets of the individual's lived experience. The existing evidence base continues to expand and new fields of enquiry are established as clinicians and researchers uncover the extent of these impacts. PRIMARY OBJECTIVE To add to recommendations described in the International Paediatric Brain Injury Society's 2016 paper on post-acute care for children with acquired brain injury and highlight new areas of enquiry. REVIEW OF INFORMATION Recommendations were made based on the opinions of a group of experienced international clinicians and researchers who are current or past members of the board of directors of the International Paediatric Brain Injury Society. The importance of each recommendation was agreed upon by means of group consensus. OUTCOMES This update gives new consideration to areas of study including injuries which occur in pre-school children, young people in the military, medical referral, young offenders and the use of technology in rehabilitation.

Abstract
OBJECTIVE To identify criteria used by sports neuropsychologists in determining recovery following sport-related concussion. METHODS Forty-six sports neuropsychologists completed a custom survey, rating the importance of specific criteria for determining concussion recovery in youth versus adults. Percentages and modal ratings were documented. RESULTS "Back to work/school without accommodations," "No headache after neurocognitive testing," "Feeling 100% back to normal," and "No symptoms after noncontact exertion" were rated highest for youth and adults. "Physician examination without concerns" and "Balance testing" were the two lowest rated items for both youth and adults. For youth, "sufficient" amount of time symptom-free needed for recovery was seen as longer than for adults. CONCLUSIONS There was some similarity in how sports neuropsychologists determine concussion recovery for both adults and youth. Future studies should include a larger sample size and concussion experts from other specialties to identify the current multidisciplinary standard of care.

Abstract
The Concussion in Sport Group guidelines have successfully brought the attention of brain injuries to the global medical and sport research communities, and has significantly impacted brain injury-related practices and rules of international sport. Despite being the global repository of state-of-the-art science, diagnostic tools and guides to clinical practice, the ensuing consensus statements remain the object of ethical and sociocultural criticism. The purpose of this paper is to bring to bear a broad range of multidisciplinary challenges to the processes and products of sport-related concussion movement. We identify lacunae in scientific research and clinical guidance in relation to age, disability, gender and race. We also identify, through multidisciplinary and interdisciplinary analysis, a range of ethical problems resulting from conflicts of interest, processes of attributing expertise in sport-related concussion, unjustifiably narrow methodological control and insufficient athlete engagement in research and policy development. We argue that the sport and exercise medicine community need to augment the existing research and practice foci to understand these problems more holistically and, in turn, provide guidance and recommendations that help sport clinicians better care for brain-injured athletes.

Multidomain Predictors of Protracted Recovery following Concussion among 5- to 9-Year-Old Patients: A Preliminary Study. J Pediatr 2024; 268:113927. [PMID: 38309522 DOI: 10.1016/j.jpeds.2024.113927] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Revised: 01/09/2024] [Accepted: 01/28/2024] [Indexed: 02/05/2024]
Abstract
OBJECTIVE To determine which components from a multidomain assessment best predict protracted recovery in pediatric patients with a concussion. STUDY DESIGN A prospective cohort of patients aged 5-9 years who presented within 21 days of concussion to a specialty clinic were categorized into normal (≤30 days) and protracted (>30 days) recovery. Participants provided demographic and medical history information, and completed the Child Sport Concussion Assessment Tool-5 symptom report and balance assessment, the Vestibular/Ocular Motor Screen-Child (VOMS-C), and the Pediatric Immediate Post-concussion Assessment and Cognitive Testing. Univariate logistic regressions (LR) were used to inform a follow-up forward stepwise LR to identify the best predictors of protracted recovery. Receiver operating characteristic analysis of the area under the curve (AUC) was used to identify which predictors retained from the LR model best discriminated recovery. RESULTS The final sample included 68 patients (7.52 ± 2.3 years; 56% male), 36 (52.9%) with normal and 32 (47.1%) with protracted recovery. Results of the LR to identify protracted recovery were significant (P < .001) and accounted for 39% of the variance. The model accurately classified 78% of patients, with days to first clinic visit (OR, 1.2; 95% CI, 1.1-1.4; P = .003) and positive VOMS-C findings (OR, 8.32; 95% CI, 2.4-28.8; P < .001) as significant predictors. A receiver operating characteristic analysis of the AUC of this 2-factor model discriminated protracted from normal recovery (AUC, 0.82; 95% CI, 0.71-0.92; P < .001). CONCLUSIONS Days to first clinic visit and positive findings on the VOMS-C were the most robust predictors of protracted recovery after concussion in young pediatric patients.

Abstract
Post-traumatic headache (PTH) represents the most common acute and persistent symptom following concussion in children, yet the underlying pathophysiology remains unclear. This systematic review sought to: (i) rigorously examine the current evidence of PTH pathophysiology in paediatric concussion (0-18 years), (ii) assess the quality of evidence, and (iii) provide directions for future research in accordance with PRISMA guidelines. Eligible studies (n = 19) totalling 1214 concussion participants investigated cerebrovascular function (n = 6), white matter integrity (n = 3), functional connectivity (n = 3), electrophysiology (n = 1), neurometabolics (n = 2), biological fluid markers (n = 4), vestibular and oculomotor function (n = 4); two studies used a multi-modal approach. Majority of studies were rated as fair quality (90%) and Level 3 evidence (84%). The true underlying mechanisms of PTH following paediatric concussion remain unclear. Overall quality of the available evidence is generally weak with a fair risk of bias and characterised by relative scarcity and lack of specificity of PTH pathophysiology. Future research is required to rigorously isolate pathophysiology specific to PTH with strict adherence to clinical definitions and standardised measurement tools of PTH.

Abstract
OBJECTIVES This study aimed to analyze changes in physical activity (PA) recommendations after pediatric concussions and examine the associations of patient and injury characteristics with physicians' PA recommendations. DESIGN Retrospective observational study. SETTING Concussion clinics associated with a pediatric hospital. PATIENTS Patients aged 10 to 18 years with a concussion diagnosis, presenting to the concussion clinic within 14 days of the injury were included. A total of 4727 pediatric concussions and corresponding 4727 discharge instructions were analyzed. INDEPENDENT VARIABLES The independent variables for our study were time, injury characteristics (eg, mechanism and symptom scores), and patient characteristics (eg, demographics and comorbidities). MAIN OUTCOME MEASURES Physician PA recommendations. RESULTS From 2012 to 2019, the proportion of physicians recommending light activity at an initial visit increased from 11.1% to 52.6% ( P < 0.05) within 1-week postinjury and from 16.9% to 64.0% during the second week postinjury ( P < 0.05). A significantly increased odds of recommending "light activity" (odds ratio [OR] = 1.82, 95% confidence interval [CI], 1.39-2.40) and "noncontact PA" (OR = 2.21, 95% CI, 1.28-2.05), compared with "no activity" within 1-week postinjury, was observed in each consecutive year. In addition, higher symptom scores at the initial visit were associated with lower likelihood of recommending "light activity" or "noncontact PA." CONCLUSIONS Physician recommendation of early, symptom-limited PA after a pediatric concussion has increased since 2012, which mirrors a shift in acute concussion management. Further research assessing how these PA recommendations may facilitate pediatric concussion recovery is warranted.

Abstract
BACKGROUND Concussion affects 1.2% of the population annually; rural regions and children have higher rates of concussion. METHODS Using administrative health care linked databases, all residents of Ontario with a physician diagnosed concussion were identified using ICD-9 code 850 or ICD-10 code S06. Cases were tracked for 2 years for concussion-related health care utilization with relevant specialist physicians (i.e., neurology, otolaryngology, physiatry, psychiatry, ophthalmology). Billing codes, specialist codes, and time from index to visit were analyzed. Factors associated with increased specialist visits were also examined. RESULTS In total, 1,022,588 cases were identified between 2008 and 2014 with 2 years of post-concussion health care utilization available. Follow-up by physician within 3 days of injury occurred in only 14% of cases. Mean time between ED diagnosis and follow-up by a physician was 83.9 days, whereas for rural regions it was >100 days. About half of adults (51.9%) and children (50.3%) had at least 1 specialist visit following concussion. Mean time between injury and first specialist visit was 203.8 (SD 192.9) days for adults, 213.5 (SD 201.0) days for rural adults, and 276.0 (SD 202.6) days for children. There were 67,420 neurology visits, 70,404 psychiatry visits, 13,571 neurosurgery visits, 19,780 physiatry visits, 101,788 ENT visits, and 103,417 ophthalmology visits in the 2 years tracking period. Factors associated with more specialist use included age > 18 years, urban residence, and pre-injury psychiatric history. CONCLUSIONS There are discrepancies in post-concussion health care utilization based on age group and rural/urban residence. Addressing these risk factors could improve concussion care access.

Abstract
The 6th International Consensus Conference on Concussion in Sport, Amsterdam 2022, addressed sport-related concussion (SRC) in adults, adolescents, and children. We highlight the updated evidence-base and recommendations regarding SRC in children (5-12 years) and adolescents (13-18 years). Prevention strategies demonstrate lower SRC rates with mouthguard use, policy disallowing bodychecking in ice hockey, and neuromuscular training in adolescent rugby. The Sport Concussion Assessment Tools (SCAT) demonstrate robustness with the parent and child symptom scales, with the best diagnostic discrimination within the first 72 hours postinjury. Subacute evaluation (>72 hours) requires a multimodal tool incorporating symptom scales, balance measures, cognitive, oculomotor and vestibular, mental health, and sleep assessment, to which end the Sport Concussion Office Assessment Tools (SCOAT6 [13+] and Child SCOAT6 [8-12]) were developed. Rather than strict rest, early return to light physical activity and reduced screen time facilitate recovery. Cervicovestibular rehabilitation is recommended for adolescents with dizziness, neck pain, and/or headaches for greater than 10 days. Active rehabilitation and collaborative care for adolescents with persisting symptoms for more than 30 days may decrease symptoms. No tests and measures other than standardized and validated symptom rating scales are valid for diagnosing persisting symptoms after concussion. Fluid and imaging biomarkers currently have limited clinical utility in diagnosing or assessing recovery from SRC. Improved paradigms for return to school were developed. The variable nature of disability and differences in evaluating para athletes and those of diverse ethnicity, sex, and gender are discussed, as are ethical considerations and future directions in pediatric SRC research.

Association between steroid use and concussions among high school athletes: a cross-sectional analysis of the Youth Risk Behavior Surveillance System. J Osteopath Med 2024; 124:27-34. [PMID: 37852286 DOI: 10.1515/jom-2023-0133] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/15/2023] [Accepted: 09/18/2023] [Indexed: 10/20/2023]
Abstract
CONTEXT In 2017, there were almost 2.5 million high school students who experienced a concussion while playing a sport, raising concern for the neurologic problems that they could face. Some of these athletes may seek to gain a competitive advantage in their sport by utilizing substances like steroids. However, steroid use can cause increased aggression and body mass index (BMI), which might lead to heightened risk for concussions. Despite extensive research, we found no previous evidence linking these two factors. OBJECTIVES This analysis aims to investigate steroid use trends in high school athletes and to determine whether there is an association between steroid use and concussions in these athletes. METHODS We conducted a cross-sectional analysis of the cumulative Youth Risk Behavior Surveillance System (YRBSS). Respondents were added if they participated in sports and answered the steroid and concussion prompts. Demographic variables were assessed including age, grade, BMI, gender, and race/ethnicity. RESULTS We found that 3.7 % (n=2991) of high school athletes reported previous steroid use and that 20.7 % (n=2273) reported having sustained a concussion. There was a statistically significant difference in steroid use by race/ethnicity (p<0.001), with the highest rate of use (7.2 %) among American Indian/Alaska Natives (AI/AN). A significantly higher prevalence of steroid use occurred in athletes who were males (4.7 %) than females (2.5 %) and in athletes with a BMI>95 % (5.2 %) compared with those with a BMI between 85 and 95 % (3.9 %) and <85 % (3.5 %) (χ2=135.1, p<0.001 and χ2=16.3, p<0.001, respectively). Further, our results showed that the prevalence of steroid use among high school athletes decreased from 3.4 % in 1999 to 1.9 % in 2019, with the most drastic drop occurring between 2015 and 2019-declining 1.9 %. Whereas 19.6 % of athletes reported a concussion without steroid use, 54.6 % of steroid-utilizing athletes reported having experienced a concussion-a statistically significant finding (adjusted odds ratio [AOR]=4.3; 95 % CI: 3.2-5.9). Finally, compared with White athletes, we found that AI/AN athletes were significantly more likely to have sustained a concussion (AOR=2.3; 95 % CI=1.2-4.3). CONCLUSIONS Although our study found decreasing rates of steroid use among high school athletes from 1999 through 2019, our results also show that steroid use is significantly associated with sustaining a concussion. Additionally, the data from YRBSS also demonstrates that AI/AN high school athletes are more likely to utilize steroids and sustain a concussion. Given the long-term consequences of traumatic brain injuries, we recommend that coaches should be aware of potential steroid use among players, and that coaches, athletic trainers, and physicians should all be aware of concussion protocols and remove players from games for evaluation when a concussion is suspected.

Brain Inj 2023; 37:1310-1325. [PMID: 37553812 DOI: 10.1080/02699052.2023.2242249] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2023] [Revised: 06/20/2023] [Accepted: 07/25/2023] [Indexed: 08/10/2023]
Abstract
OBJECTIVES 1) To describe demographic factors, concussion knowledge, attitudes, subjective norms, self-efficacy and intentions to provide social support to a peer with a concussion and 2) to examine if demographic factors and concussion knowledge are associated with components of the Theory of Planned Behavior. METHODS The survey was completed between October 2018 and February 2019 by 200 youth (M = 15.30 years, SD = 1.52). Questions were designed for athletes and non-athletes and inquired about various types of social support. Data analysis included descriptive statistics, Wilcoxon Rank Sum Tests and Spearman's Rank-Order Correlation Coefficients. RESULTS More favorable attitudes and intentions to provide social support were observed among females (W = 2576, p ≤ 0.001; W = 2411, p ≤ 0.001), older youth (rho = 0.32, p ≤ 0.001; rho = 0.41, p ≤ 0.001) and those with higher concussion knowledge (rho = 0.29, p ≤ 0.001; rho = 0.22; p ≤ 0.001). Participating in sports with a high-risk of concussion was associated with lower attitudes and intentions to provide social support (W = 6677; p ≤ 0.001; W = 6721; p ≤ 0.001). Self-reported concussion history or knowing someone with a concussion history was not significantly associated with social support intentions. CONCLUSION This study identified characteristics of youth who had positive intentions to provide social support. These findings identify individuals who may model providing social support to a peer, as well as opportunities for future concussion education.

Abstract
Finding reliable biomarkers to assess concussions could play a pivotal role in diagnosis, monitoring, and predicting associated risks. The present study aimed to explore the use of heart rate variability (HRV) in the follow-up of concussions among college athletes and to investigate the relationships between biological sex, symptomatology, and HRV values at baseline and after a concussion. Correlations between measures were also analyzed. A total of 169 (55 females) athletes aged 16 to 22 years old completed baseline testing, and 30 (8 females) concussion cases were followed. Baseline assessment (T1) included psychosocial and psychological questionnaires, symptoms report, and four minutes of HRV recording. In the event of a concussion, athletes underwent re-testing within 72 h (T2) and before returning to play (T3). Baseline findings revealed that girls had higher %VLF while sitting than boys, and a small negligible correlation was identified between %HF and total symptoms score as well as %HF and affective sx. Post-concussion analyses demonstrated a significant effect of time × position × biological sex for %HF, where girls exhibited higher %HF at T3. These findings suggest disruptions in HRV following a concussion and underscore biological sex as an important factor in the analysis of HRV variation in concussion recovery trajectory.

Abstract
BACKGROUND Rates of sports-related concussion (SRC) are high in adolescents. Ambiguity exists regarding the effect of SRC on cognitive function in adolescents. PURPOSE To rigorously examine adolescents' cognitive function after SRC. STUDY DESIGN Systematic review and meta-analysis; Level of evidence, 4. METHODS Web of Science, Scopus, and PubMed were searched from database inception until September 2021. Studies were included if participants were adolescents aged 13 to 18 years, if the definition of SRC was fully consistent with the Berlin Consensus Statement on Concussion in Sport, if the study included a control group or in-group baseline test, and if the study reported cognitive outcomes (eg, visual memory, processing speed) that could be separately extracted. RESULTS A total of 47 studies were included in the systematic review, of which 31 were included in the meta-analysis, representing 8877 adolescents with SRC. Compared with individuals in the non-SRC group, individuals with SRC had worse performance in cognitive function and reported more symptoms not only in the acute phase but also in the prolonged phase (1-6 months after injury) (visual memory: d = -0.21, 95% CI, -0.37 to -0.05, P = .012; executive function: d = -0.56, 95% CI, -1.07 to -0.06, P = .028; and symptoms: d = 1.17, 95% CI, 0.13 to 2.22, P = .028). Lower scores in most of the outcomes of cognitive function were observed at <3 days and at 3 to 7 days, but higher scores for verbal memory (d = 0.10; 95% CI, 0.03 to 0.17; P = .008) and processing speed (d = 0.17; 95% CI, 0.10 to 0.24; P < .001) were observed at 7 to 14 days after SRC relative to baseline. The effects of SRC on cognitive function decreased over time (100% of the variance in reaction time, P < .001; 99.94% of the variance in verbal memory, P < .001; 99.88% of the variance in visual memory, P < .001; 39.84% of the variance in symptoms, P = .042) in control group studies. Study design, participant sex, measurement tools, and concussion history were found to be modulators of the relationship between cognitive function and SRC. CONCLUSION This study revealed that adolescent cognitive function is impaired by SRC even 1 to 6 months after injury. Results of this study point to the need for tools to measure cognitive function with multiple parallel versions that have demographically diversiform norms in adolescents. Effective prevention of SRC, appropriate treatment, and adequate evaluation of cognitive function before return to play are needed in adolescent SRC management. Moreover, caution is warranted when using the baseline-to-postconcussion paradigm in return-to-play decisions.

From acute stress to persistent post-concussion symptoms: The role of parental accommodation and child's coping strategies. Clin Neuropsychol 2023; 37:1389-1409. [PMID: 36416168 DOI: 10.1080/13854046.2022.2145578] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/01/2022] [Accepted: 11/04/2022] [Indexed: 11/24/2022]
Abstract
Background: Acute stress following mild Traumatic Brain Injury (mTBI) is highly prevalent and associated with Persistent Post-Concussion symptoms (PPCS). However, the mechanism mediating this relationship is understudied. Objective: To examine whether parental accommodation (i.e. parents' attempts to adjust the environment to the child's difficulties) and child's coping strategies mediate the association between acute stress and PPCS in children following mTBI. Method: Participants were 58 children aged 8-16 who sustained a mTBI and their parents. Children's acute stress (one-week post-injury) and coping strategies (three weeks post-injury), and parental accommodation (three weeks and four months post-injury) were assessed. Outcome measures included PPCS (four months post-injury) and neuropsychological tests of cognitive functioning (attention and memory). A baseline for PPCS was obtained by a retrospective report of pre-injury symptoms immediately after the injury. Results: Children's acute stress and negative coping strategies (escape-oriented coping strategies) and four-months parental accommodation were significantly related to PPCS. Acute stress predicted PPCS and attention and memory performance. Parental accommodation significantly mediated the association between acute stress and PPCS. Conclusions: Stress plays an important role in children's recovery from mTBI and PPCS. Parental accommodation mediates this relationship, and thus, clinical attention to parental reactions during recovery is needed.

Abstract
BACKGROUND TBI during adolescence can result in significant acute symptoms that can persist into adulthood. This research analyzed retrospective qualitative accounts of young adults who had sustained a TBI in adolescence to explore coping and recovery processes specific to this developmental stage. METHODS Thirteen adults (aged 20-25 years; mean 23 years) who sustained a mild (n = 12) or moderate (n = 1) TBI during adolescence (aged 13-17 years at injury), approximately 7.7 years (range = 6.7-8.0 years) prior, participated. Semi-structured individual interviews, analyzed using thematic analysis, explored participants' experiences following their TBIs. RESULTS Thematic data analysis produced two key categories of themes relating to recovery processes: (1) Individual factors impacting coping, with themes of learning to cope with difficulties, seeking acceptance and balance, and finding meaning; and (2) Social factors impacting coping, which included themes of feeling included, relying on family, professionals didn't get it, and lacking someone who understands. CONCLUSIONS Recovery following TBI sustained during adolescence could be maximized by facilitating greater understanding of specific impacts on young people among clinicians and family, longer term monitoring of symptoms including emotional reactions to symptoms, and the provision of emotional support.

Abstract
INTRODUCTION Sport-related concussion is one of the most common injuries in adolescent rugby players with evidence of prolonged recovery in some concussed athletes. Concussion is a complex pathophysiological process that can affect a variety of subsystems with multifactorial presentation. Most research on adolescents recovery after concussion focuses on neurocognitive functioning and symptom outcomes over the short term. There is a need to explore concussion recovery over time across multiple subsystems in adolescent rugby players. METHODS AND ANALYSIS This prospective study will use sensorimotor and oculomotor outcomes in adolescent male and female rugby players aged 16-18 years. Players will be recruited from school or club rugby teams across the province of Ulster. Baseline assessment will be undertaken at the start of the playing season and will include questionnaires, Quantified Y Balance Test and Pupillary Light Reflex. Players who sustain a concussive event will be reassessed on all outcomes at 3 days, 7 days, 14 days, 23 days, 90 days, 180 days and 365 days postconcussion. For serial outcome data, we will examine response curves for each participant and make comparisons between known groups. We will use logistic regression to explore any association between demographic variables and recovery. The strength of the predictive model will be determined using R2, p values and ORs, with 95% CIs. ETHICS AND DISSEMINATION Ethical approval has been granted for this study from Ulster University Research Ethics Committee (REC/14/0060). This study will be published in an open-access research journal on completion. TRIAL REGISTRATION NUMBER ACTRN12622000931774p.

Abstract
OBJECTIVE To determine the long-term risk of new adverse psychosocial outcomes among adolescents diagnosed with a concussion compared with those not diagnosed. STUDY DESIGN A retrospective, population-based cohort study was conducted. Adolescents (10-18 years) with a physician-diagnosed concussion between 2000 and 2005 were matched on neighborhood and age with 5 controls without concussion from the general population. New-onset mental health disorders, medication use, social, and justice outcomes were extracted using datasets linked to the population data repository. Adolescents were followed for 11-16 years. Adjusted hazard ratios (95% CIs) were estimated. RESULTS In total, 2082 adolescents with a concussion were matched to 10 510 without. Adolescents with a concussion had an increased risk of any mental health disorder (HR 1.34; 95% CI 1.25-1.45), mood disorder (HR 1.30; 95% 1.18-1.43), psychosis (HR 1.43; 95% CI 1.18-1.74), substance abuse disorder (HR 1.67; 95% 1.31-2.14), and receiving a psychotropic prescription (HR 1.31; 95% CI 1.20-1.42). Female adolescents had an increased risk of ADHD following concussion (HR 1.89; 95% CI 1.17-3.05). Adolescents with a concussion had an increased risk of being accused (HR 1.22; 95% CI 1.11-1.34), victim (HR 1.29; 95% CI 1.11-1.48), or witness (HR 1.16; 95% CI 1.01-1.32) of a crime, or contact with Child and Family Services (HR 1.33; 95% CI 1.10-1.62). There was no association between concussion and attempting or completing suicide, receiving housing support, or collecting income support. CONCLUSIONS Concussion was associated with an increased risk for multiple adverse psychosocial outcomes. Future work should focus on early identification of those at risk of these outcomes to help optimize longitudinal medical care and support.

Abstract
SUMMARY Sport-related concussion (SRC) has been defined as a subset of mild traumatic brain injury (mTBI), without structural abnormalities, reflecting a functional disturbance. Over the past decade, SRC has gained increasing awareness and attention, which coincides with an increase in incidence rates. Because this injury has been considered one of the most challenging encounters for clinicians, there is a need for objective biomarkers to aid in diagnosis (i.e., presence/severity) and management (i.e., return to sport) of SRC/mTBI.The primary aim of this article was to present state-of-the-art neurophysiologic methods (e.g., electroencephalography, magnetoencephalography, transcranial magnetic stimulation, and autonomic nervous system) that are appropriate to investigate the complex pathophysiological process of a concussion. A secondary aim was to explore the potential for evidence-based markers to be used in clinical practice for SRC management. The article concludes with a discussion of future directions for SRC research with specific focus on clinical neurophysiology.

Abstract
OBJECTIVE To determine what tests and measures accurately diagnose persisting post-concussive symptoms (PPCS) in children, adolescents and adults following sport-related concussion (SRC). DESIGN A systematic literature review. DATA SOURCES MEDLINE, Embase, PsycINFO, Cochrane Central Register of Controlled Trials, CINAHL and SPORTDiscus through March 2022. ELIGIBILITY CRITERIA Original, empirical, peer-reviewed findings (cohort studies, case-control studies, cross-sectional studies and case series) published in English and focused on SRC. Studies needed to compare individuals with PPCS to a comparison group or their own baseline prior to concussion, on tests or measures potentially affected by concussion or associated with PPCS. RESULTS Of 3298 records screened, 26 articles were included in the qualitative synthesis, including 1016 participants with concussion and 531 in comparison groups; 7 studies involved adults, 8 involved children and adolescents and 11 spanned both age groups. No studies focused on diagnostic accuracy. Studies were heterogeneous in participant characteristics, definitions of concussion and PPCS, timing of assessment and the tests and measures examined. Some studies found differences between individuals with PPCS and comparison groups or their own pre-injury assessments, but definitive conclusions were not possible because most studies had small convenience samples, cross-sectional designs and were rated high risk of bias. CONCLUSION The diagnosis of PPCS continues to rely on symptom report, preferably using standardised symptom rating scales. The existing research does not indicate that any other specific tool or measure has satisfactory accuracy for clinical diagnosis. Future research drawing on prospective, longitudinal cohort studies could help inform clinical practice.

Abstract
OBJECTIVE To define the time frames, measures used and modifying factors influencing recovery, return to school/learn (RTL) and return to sport (RTS) after sport-related concussion (SRC). DESIGN Systematic review and meta-analysis. DATA SOURCES 8 databases searched through 22 March 2022. ELIGIBILITY CRITERIA Studies with diagnosed/suspected SRC and interventions facilitating RTL/RTS or investigating the time and modifying factors for clinical recovery. Outcomes included days until symptom free, days until RTL and days until RTS. We documented study design, population, methodology and results. Risk of bias was evaluated using a modified Scottish Intercollegiate Guidelines Network tool. RESULTS 278 studies were included (80.6% cohort studies and 92.8% from North America). 7.9% were considered high-quality studies, while 23.0% were considered high risk of bias and inadmissible. The mean days until symptom free was 14.0 days (95% CI: 12.7, 15.4; I2=98.0%). The mean days until RTL was 8.3 (95% CI: 5.6, 11.1; I2=99.3%), with 93% of athletes having a full RTL by 10 days without new academic support. The mean days until RTS was 19.8 days (95% CI: 18.8, 20.7; I2=99.3%), with high heterogeneity between studies. Several measures define and track recovery, with initial symptom burden remaining the strongest predictor of longer days until RTS. Continuing to play and delayed access to healthcare providers were associated with longer recovery. Premorbid and postmorbid factors (eg, depression/anxiety, migraine history) may modify recovery time frames. Though point estimates suggest that female sex or younger age cohorts take longer to recover, the heterogeneity of study designs, outcomes and overlap in CIs with male sex or older age cohorts suggests that all have similar recovery patterns. CONCLUSION Most athletes have full RTL by 10 days but take twice as long for an RTS. PROSPERO REGISTRATION NUMBER CRD42020159928.

Abstract
OBJECTIVES We evaluated interventions to facilitate recovery in children, adolescents and adults with a sport-related concussion (SRC). DESIGN Systematic review including risk of bias (modified Scottish Intercollegiate Guidelines Network tool). DATA SOURCES MEDLINE(R) and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Embase, APA PsycINFO, Cochrane Central Register of Controlled Trials, CINAHL Plus with Full Text, SPORTDiscus and Scopus searched until March 2022. STUDY ELIGIBILITY CRITERIA (1) Original research including randomised controlled trials (RCTs), quasi-experimental designs, cohort, comparative effectiveness studies; (2) focus on SRC; (3) English; (4) peer-reviewed and (5) evaluated treatment. RESULTS 6533 studies were screened, 154 full texts reviewed and 13 met inclusion (10 RCTs, 1 quasi-experimental and 2 cohort studies; 1 high-quality study, 7 acceptable and 5 at high risk of bias). Interventions, comparisons, timing and outcomes varied, precluding meta-analysis. For adolescents and adults with dizziness, neck pain and/or headaches >10 days following concussion, individualised cervicovestibular rehabilitation may decrease time to return to sport compared with rest followed by gradual exertion (HR 3.91 (95% CI 1.34 to 11.34)) and when compared with a subtherapeutic intervention (HR 2.91 (95% CI 1.01 to 8.43)). For adolescents with vestibular symptoms/impairments, vestibular rehabilitation may decrease time to medical clearance (vestibular rehab group 50.2 days (95% CI 39.9 to 60.4) compared with control 58.4 (95% CI 41.7 to 75.3) days). For adolescents with persisting symptoms >30 days, active rehabilitation and collaborative care may decrease symptoms. CONCLUSIONS Cervicovestibular rehabilitation is recommended for adolescents and adults with dizziness, neck pain and/or headaches for >10 days. Vestibular rehabilitation (for adolescents with dizziness/vestibular impairments >5 days) and active rehabilitation and/or collaborative care (for adolescents with persisting symptoms >30 days) may be of benefit.

Abstract
BACKGROUND The relationship between pediatric Traumatic Brain Injury (TBI) and long-term mental health and substance use disorders is not well known, resulting in inadequate prevention and management strategies. The aim of this scoping review is to review the evidence on pediatric TBI and the development of mental health disorders and substance use later in life and to identify gaps in the literature to inform future research. METHODS We searched multiple databases for original articles published between September 2002 and September 2022 on TBI-related mental health and/or substance use disorders in children and youth. Two independent reviewers performed the screening using Arksey and O'Malley and Levac et al.'s scoping review framework. RESULTS A total of six papers are included in this scoping review. Studies included are comprised of cross-sectional and prospective longitudinal cohort studies. DISCUSSION A correlation between pediatric TBI and development of certain mental health disorders and substance use is suggested, although much of the current evidence is mixed and does not account for confounding variables. Future studies should aim to closely examine these links and identify modifiers that can influence these relationships.

Abstract
OBJECTIVE To examine differences in individual symptom report prevalence between children and adolescents experiencing 1 to 2 versus ≥3 persistent postconcussion symptoms. DESIGN A prospective cohort study. SETTING Three community practice concussion clinics within a family practice network. PATIENTS Children and adolescents aged 8 to 18 years presenting to clinics within 72 hours of a sport-related or recreation-related concussion. Those with complete symptom data from a 1-month follow-up time point (n = 236) were included in analyses. INDEPENDENT VARIABLES One hundred thirty-six patients (n = 136) reported 0 symptoms as worse than preinjury at the 1-month time point. Participants reporting 1+ symptoms as worse than preinjury at 1 month were assigned to groups based on the number of symptoms endorsed: those with 1 to 2 (n = 38) compared with those experiencing ≥3 (n = 62). MAIN OUTCOME MEASURES Fisher exact tests were used to compare symptom report prevalence for each item of the Rivermead Postconcussion Symptoms Questionnaire. This research question was formulated and examined after completion of data collection. RESULTS Across both groups, headache and fatigue were the most commonly reported persistent postconcussion symptoms. Several emotional symptoms (eg, irritability, depression) were primarily or only present in those reporting ≥3 persistent symptoms. CONCLUSIONS Findings provide detail regarding the clinical manifestation of experiencing fewer versus more persistent postconcussion symptoms, underscoring the importance of developing individualized, multifaceted rehabilitation programs.

Abstract
OBJECTIVES To assess the association between early physical activity and post-concussion sleep quality, dizziness, and postural stability among adolescents with concussion compared to uninjured controls. DESIGN Cross-sectional. METHODS Adolescents ages 13-18 years assessed within 14 days post-concussion and uninjured controls. Those with concussion reported if they participated in physical activity between the concussion and assessment. Participants completed the Dizziness Handicap Inventory, Pittsburgh Sleep Quality Index, and single/dual-task tandem gait. RESULTS We enrolled 34 participants with concussion (early physical activity: n = 10, age = 15.8 ± 1.6 years, 70% female; no physical activity: n = 24, age = 16.0 ± 1.3 years, 50% female) and 21 uninjured controls (age = 16.0 ± 1.8 years, 48% female). Compared to controls, the no physical activity group reported worse sleep quality (Pittsburgh Sleep Quality Index: 3.8 ± 2.7 vs 8.0 ± 4.9 points, p = 0.002) and single-task tandem gait time (13.7 ± 3.4 vs 21.2 ± 8.1 s, p = 0.0006), while the early physical activity group did not (Pittsburgh Sleep Quality Index: 3.8 ± 2.7 vs 5.8 ± 3.2 points, p = 0.38; single-task tandem gait: 13.7 ± 3.4 vs 19.0 ± 5.7 s, p = 0.08). Compared to controls, early/no physical activity groups reported worse dizziness (Dizziness Handicap Inventory: 2.0 ± 3.4 vs 22.9 ± 23.8 vs 27.4 ± 19.2 points, p < 0.0001). There were no significant between-group differences for dual-task tandem gait (24.1 ± 8.0 vs 24.8 ± 6.2 vs 26.6 ± 7.3 s, p = 0.57). CONCLUSIONS The no physical activity group reported worse sleep quality and slower single-task tandem gait than controls, while both groups reported similar sleep quality and tandem gait. Early physical activity may promote sleep quality and postural stability, or early physical activity may be a function of improved sleep and postural stability after concussion.

Abstract
OBJECTIVE To compare concussion rates (CRs) over one academic year in high school athletes with and without a COVID-19 infection prior to concussion. METHODS Illness and concussion were prospectively reported for male and female high school athletes across six states over one academic year in the Players Health Rehab surveillance system. Concussion was truncated to 60 days following recovery and return to sport from COVID-19. CRs were estimated per 1000 athletes per academic year and stratified by those who tested positive for COVID-19 infection (with COVID-19) and those who did not (no COVID-19). Poisson regression analyses estimated rate ratio (RR) of concussion controlling for state, gender and an offset of the log athlete participation (with COVID-19 and no COVID-19). RESULTS Of 72 522 athletes, 430 COVID-19 infections and 1273 concussions were reported. The CR was greater in athletes who reported COVID-19 (CR=74.4/1000 athletes/year, 95% CI 49.6 to 99.3) compared with those who did not (CR=17.2, 95% CI 16.3 to 18.2). Athletes with recent COVID-19 had a threefold higher rate of concussion (RR=3.1, 95% CI 2.0 to 4.7). CONCLUSION Athletes returning from COVID-19 had higher CRs than those who did not experience COVID-19. This may be related to ongoing COVID-19 sequelae or deconditioning related to reduced training and competition load during the illness and when returning to sport. Further research is needed to understand the association of recent COVID-19 infection and concussion in order to inform preventive strategies.

Abstract
BACKGROUND Concussions affect millions of youths in the United States each year, and there is concern about long-term health effects from this injury. PURPOSE To examine the association between sports- or physical activity-related concussion and health risk behaviors among middle and high school students in 9 states. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS Data from the 2019 middle school and high school Youth Risk Behavior Survey were used for this analysis. Nine states were identified that included the same question on concussion and similar questions on health risk behaviors in their 2019 Youth Risk Behavior Survey. Students were asked to self-report whether they had ≥1 sports- or physical activity-related concussions during the 12 months preceding the survey. Self-reported concussion was the primary outcome of interest. Other variables included sex, race/ethnicity, played on a sports team, were physically active 5 or more days/week, ever tried cigarette smoking, ever used an electronic vapor product, academic grades, drank alcohol, were in a physical fight, seriously considered attempting suicide, made a suicide plan, and attempted suicide. RESULTS Among the 9 states, 18.2% of middle school students and 14.3% of high school students self-reported ≥1 sports- or physical activity-related concussions. Among both middle school and high school students, the prevalence of ≥1 sports- or physical activity-related concussions was higher among students who played on a sports team, were physically active 5 or more days per week, had ever tried cigarette smoking, had ever used an electronic vapor product, had seriously considered attempting suicide, had made a suicide plan, and had attempted suicide compared with those who had not engaged in those behaviors. The prevalence of sports- or physical activity-related concussion was consistently higher among middle school students than high school students across sex, race/ethnicity, and adverse health behaviors. CONCLUSION Middle school students with a history of concussion warrant attention as an at-risk population for concussions and adverse health behaviors. Health care providers may consider screening students for adverse health behaviors during preparticipation examinations and concussion evaluations.

Abstract
Importance Determining how the timing of return to school is related to later symptom burden is important for early postinjury management recommendations. Objective To examine the typical time to return to school after a concussion and evaluate whether an earlier return to school is associated with symptom burden 14 days postinjury. Design, Setting, and Participants Planned secondary analysis of a prospective, multicenter observational cohort study from August 2013 to September 2014. Participants aged 5 to 18 years with an acute (<48 hours) concussion were recruited from 9 Canadian pediatric emergency departments in the Pediatric Emergency Research Canada Network. Exposure The independent variable was the number of days of school missed. Missing fewer than 3 days after concussion was defined as an early return to school. Main Outcomes and Measures The primary outcome was symptom burden at 14 days, measured with the Post-Concussion Symptom Inventory (PCSI). Symptom burden was defined as symptoms status at 14 days minus preinjury symptoms. Propensity score analyses applying inverse probability of treatment weighting were performed to estimate the relationship between the timing of return to school and symptom burden. Results This cohort study examined data for 1630 children (mean age [SD] 11.8 [3.4]; 624 [38%] female). Of these children, 875 (53.7%) were classified as having an early return to school. The mean (SD) number of days missed increased across age groups (5-7 years, 2.61 [5.2]; 8-12 years, 3.26 [4.9]; 13-18 years, 4.71 [6.1]). An early return to school was associated with a lower symptom burden 14 days postinjury in the 8 to 12-year and 13 to 18-year age groups, but not in the 5 to 7-year age group. The association between early return and lower symptom burden was stronger in individuals with a higher symptom burden at the time of injury, except those aged 5 to 7 years. Conclusions and Relevance In this cohort study of youth aged 5 to 18 years, these results supported the growing belief that prolonged absences from school and other life activities after a concussion may be detrimental to recovery. An early return to school may be associated with a lower symptom burden and, ultimately, faster recovery.

Abstract
Concussion is a type of mild traumatic brain injury which results in symptoms within the physical, cognitive, emotional, and sleep domains. Historically, guidelines established by expert opinion have recommended rest during the initial stages of recovery following a concussion until symptom resolution. However, recent recommendations have shifted to advise an initial period of 24-48 h of rest immediately following concussion with the gradual introduction of light-to-moderate intensity aerobic exercise thereafter. Given the relatively recent transition in recommendations, the aim of this review is to provide an overview of the current literature on the efficacy of aerobic exercise following concussion. The current literature is limited to studies assessing the impact of standardized aerobic exercise following concussion. Upon review, literature suggests participating in aerobic exercise below the point of symptom exacerbation is safe in both the acute and chronic post-concussion symptom stages of recovery and does not delay time to medical clearance. Future large-scale randomized controlled trials assessing the impact of aerobic exercise and differences between males and females would help support the current evidence suggesting aerobic exercise could improve time to recovery following concussion and identify any sex differences in response. As well, future studies with the purpose of identifying optimal aerobic exercise volume and intensity in the treatment of concussion could improve the specificity of the current guidelines.

Environmental temperature adversely affects the outcome of concussive head injury (CHI)-induced brain pathology. Studies from our laboratory showed that animals reared at either cold environment or at hot environment exacerbate brain pathology following CHI. Our previous experiments showed that nanowired delivery of oxiracetam significantly attenuated CHI-induced brain pathology and associated neurovascular changes. Military personnel are the most susceptible to CHI caused by explosion, blasts, missile or blunt head trauma leading to lifetime functional and cognitive impairments affecting the quality of life. Severe CHI leads to instant death and/or lifetime paralysis. Military personnel engaged in combat operations are often subjected to extreme high or low environmental temperature zones across the globe. Thus, further exploration of novel therapeutic agents at cold or hot ambient temperatures following CHI are the need of the hour. CHI is also a major risk factor for developing Alzheimer's disease by enhancing amyloid beta peptide deposits in the brain. In this review, effect of hot environment on CHI-induced brain pathology is discussed. In addition, whether nanodelivery of oxiracetam together with neprilysin and monoclonal antibodies (mAb) to amyloid beta peptide and p-tau could lead to superior neuroprotection in CHI is explored. Our results show that co-administration of oxiracetam with neprilysin and mAb to AβP and p-tau significantly induced superior neuroprotection following CHI in hot environment, not reported earlier.

[PMID: 36935886 PMCID: PMC10020172 DOI: 10.3389/fspor.2023.1064771] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2022] [Accepted: 02/13/2023] [Indexed: 03/06/2023] Open
Abstract
Background A visio-vestibular home exercise program (VV-HEP) can provide an equitable and cost-effective method for therapy targeted towards visio-vestibular deficits that are common following concussion. The effects of a VV-HEP on improving concussion symptoms and visio-vestibular function are unclear. Purpose Determine the effect of VV-HEP on symptoms and visio-vestibular function in concussed pediatric patients. Methods This study included 527 patients [294 female (55.8%); age = 14.4 ± 2.1 years] reporting to a specialty care concussion center within 28 days of injury and for a first follow-up within 60 days of injury. Patients completed the Post-Concussion Symptom Inventory (PCSI) and Visio-Vestibular Examination (VVE). Patients were prescribed the VV-HEP at initial visit, with exercises including saccades, gaze stability, convergence, and balance, and instructed to complete these 1-2 times/day. At follow-up, patients self-reported their VV-HEP progress as (1) has not done, (2) in progress, or (3) completed. Primary outcomes included VV-HEP progress at follow-up, PCSI endorsement and severity, VVE subtests (normal/abnormal), and total VVE score (abnormal = 2 + abnormal subtests). Kruskal-Wallis tests and chi-square were used to determine if concussion symptoms or the proportion of abnormal VVE outcomes, respectively, were associated with VV-HEP status. Post-hoc pairwise comparisons with Bonferonni corrections were used to determine concussion symptom (α = 0.017 a priori) and VVE (α = 0.005 a priori) differences in VV-HEP status. Results At follow-up, patients who had completed the VV-HEP reported lower symptom endorsement (median = 1, IQR = 0-3) and lower symptom severity (median = 1, IQR = 0-4) relative to patients who had not started the VV-HEP (endorsement median = 7, IQR = 1-13, p < 0.0001; severity median = 15.5, IQR = 2-32.5, p < 0.0001) and those in progress (endorsement median = 8, IQR = 3-14, p < 0.0001; severity median = 15, IQR = 4-30, p < 0.0001). A lower proportion of patients who completed the VV-HEP reported with abnormal vestibular-ocular reflex (22.2%), tandem gait (0%), and total VVE score (22.2%) relative to those who had not started or those in progress (p < 0.005). Conclusion Our findings indicate that patients who completed the VV-HEP had lower symptom burden and improved visio-vestibular function relative to those who did not start or were in progress. This suggests that a VV-HEP can effectively reduce visio-vestibular dysfunction following concussion and may serve as a means to minimize inequities in access to care.

Abstract
Objective This study aimed to identify school problems and levels of cognitive activity in youths aged 5-18 years with a concussion during the recovery stages of return to school (RTS). Study Design In a prospective cohort, participants completed in-person assessments at three time points: First Visit Post-injury, Symptom Resolution Visit, and Follow-Up Visit. These time points varied based on the participants' recovery progress. The post-concussion symptom scale (PCSS) and a cognitive activity scale were completed every 2 days until symptom resolution was achieved. Participants and their parents completed a school questionnaire detailing how their concussion had impacted their school learning/performance and their level of concern about their injury as well as the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). Results Sixty-three percent (N = 44/70) of participants returned to school by the First Visit Post-injury (average 7.7 days following injury), and of these, 50% (N = 22) were experiencing school problems. Sixty-five participants (out of 70) returned to school at the Follow-Up Visit, and of these, 18% reported school problems. There was a significant difference in the school problems reported by parents and youth. At the First Visit Post-injury, the youth reported more problems (p = 0.02), and the In-Person Symptom Resolution Visit with parents reported more problems (p = 0.01). The cognitive activity score increased, while the PCSS score decreased from RTS Stage 1 to Stage 5. Conclusions This study identified that 50% of youth experienced school problems at the First Visit Post-injury, whereas only 18% reported school problems at the Follow-Up Visit. There is a significant difference in the perception of school problems reported by youth and their parents at different stages of recovery. The amount and complexity of cognitive activity increased with decreasing symptoms and increasing RTS stage. Findings can guide youth with a concussion and their parents in supporting a cautious return to school with accommodations. Healthcare providers and researchers can use this knowledge to better support youth in their return to school and understand the importance of gathering information from youth and their parents to gain the best insight into recovery.

Abstract
Aims The aim of this study was to develop a gross motor performance clinical assessment tool, the Concussion Challenge Assessment (CCA), for paediatric concussion populations. Methods An expert panel evaluated tasks from the Acquired Brain Injury Challenge Assessment to determine relevant tasks for a paediatric concussion population. These tasks were administered to a convenience sample of 854 healthy youth. An analysis of the response options for each task, considering task difficulty, was performed. The test-retest reliability of each task was considered to finalise the tool. Results The Acquired Brain Injury Challenge Assessment was reduced to six tasks (three coordination, two speed and agility, and one strength) to create the CCA. Population-specific 4-point response options were generated, which, upon examination of task difficulty, were revised as 5-point response sets to better capture performance differences. The test-retest reliability results led to acceptance of all six: three performance tasks and three exertion tasks. Conclusion This development of the CCA is an important step in creating a gross motor performance assessment tool that can assist in the determination of when youth are able to safely return to activity following a concussion.

Abstract
OBJECTIVE Vestibular and ocular motor dysfunction occurs in an estimated 60%-90% of concussion patients. The Vestibular/Ocular Motor Screening (VOMS) tool is validated for use in concussion patients older than 9 years. The goal of the current study was to adapt the current VOMS tool for a pediatric sample of children aged 5-9 years and establish its clinical utility in this patient population. METHODS In this case-control study, 80 symptomatic concussion patients (n = 33 [41%] female) aged 5-9 years (mean age 7.40 ± 1.09 years) and 40 (n = 18 [45%] female) age- and sex-matched uninjured controls (mean age 7.10 ± 1.26 years) completed the VOMS-Child (VOMS-C), a version of the VOMS adapted for younger patients. Differences in binary "yes" or "no" symptom provocation for headache, dizziness, and nausea/"tummy ache" across the 7 items of the VOMS-C, and near point of convergence (NPC) distance, were examined. Logistic regression (LR) models were built to classify concussion and controls. Predicted probabilities were generated from the LR model and entered into receiver operating characteristic (ROC) curve models to generate area under the curve (AUC) values. RESULTS VOMS-C item provocation ranged from 13% to 30% for concussed patients and 3% to 20% for controls. The LR model distinguished concussed participants from controls (R2 = 0.39; p < 0.001), with significant predictors being smooth pursuits, family depression history, and NPC distance. The ROC analysis had an AUC of 0.81 (95% CI 0.73-0.89; p < 0.001) in the good range. CONCLUSIONS Accurate diagnosis of concussion in the clinic setting requires comprehensive evaluation in multiple domains, including detailed clinical interview, neurocognitive testing, and vestibular/ocular motor assessment, regardless of patient age. Our results provide preliminary support for the VOMS-C as a developmentally appropriate tool for concussion management.

Abstract
Visual and vestibular deficits, as measured by a visio-vestibular examination (VVE), are markers of concussion in youth. Little is known about VVE evolution post-injury, nor influence of age or sex on trajectory. The objective was to describe the time trend of abnormal VVE elements after concussion. Two cohorts, 11-18 years, were enrolled: healthy adolescents (n = 171) from a high school with VVE assessment before or immediately after their sport seasons and concussed participants (n = 255) from a specialty care concussion program, with initial assessment ≤28 days from injury and VVE repeated throughout recovery during clinical visits. The primary outcome, compared between groups, is the time course of recovery of the VVE examination, defined as the probability of an abnormal VVE (≥2/9 abnormal elements) and modeled as a cubic polynomial of days after injury. We explored whether probability trajectories differed by: age (<14 years vs. 14+ years), sex, concussion history (0 versus 1+), and days from injury to last assessment (≤28 days vs. 29+ days). Overall, abnormal VVE probability peaked at 0.57 at day 8 post-injury, compared with an underlying prevalence of 0.083 for uninjured adolescents. Abnormal VVE probability peaked higher for those 14+ years, female, with a concussion history and whose recovery course was longer than 28 days post-injury, compared with their appropriate strata subgroups. Females and those <14 years demonstrated slower resolution of VVE abnormalities. VVE deficits are common in adolescents after concussion, and the trajectory of resolution varies by age, sex, and concussion history. These data provide insight to clinicians managing concussions on the timing of deficit resolution after injury.

Abstract
New Zealand Rugby (NZR) implemented a concussion management pathway (CMP), aimed at improving management at community level. General Practitioners (GPs) played a large role in the design of this process. The objective of this study was to explore GPs' perceptions of barriers and facilitators of the CMP and rugby-related concussion management in the community. A descriptive qualitative approach using interviews and focus groups was employed. Four themes were derived: i) GPs' existing knowledge and confidence around concussion management; ii) Operational resources: time, remuneration and pathway guidance; iii) Standardising concussion care and iv) Expanding the circle of care - the need for multi-disciplinary healthcare team. These themes described how GP's concussion knowledge, and the efficiency and availability of operational resources affected their experience and ability to fulfil their tasks within the CMP. GPs found NZR's CMP especially valuable, as it provided guidance and structure. Expanding the role of other healthcare providers was seen as critical to reduce the burden on GPs, while also delivering a more holistic experience to improve clinical outcomes. Addressing the identified barriers and expanding the network of care will help to improve the ongoing development of NZR's CMP, while supporting continued engagement with all stakeholders.
