Objective: To evaluate access to optimal concussion care based on a pediatric patients' geography; the hypothesis is that differential access across the Unites States exists. Design: Employed a novel strategy using internet searches to find local care, mimicking what families might do in different parts of the country. Setting: Virtual internet searches. Participants: Not applicable. Independent Variable: Various metropolitan and rural geographic regions within each state in the United States. Main Outcome Measures: Evaluate access (defined as distance to clinic and ability to see pediatric patients) and optimal care (defined as self-referral process and presence of multidisciplinary care). Results: Search strategy yielded 490 results. Overall; 60% were within 50 miles of searched locations with significant differences in access based on rural versus metropolitan areas (P, 0.0001); in rural areas, only; 22% of results were within 50 miles. Only about one-third of the results (n 5 157) saw pediatric patient with no differences between regions. There was significant regional and geographic variation for optimal care regarding both self-referral processes and access to multidisciplinary care. A diverse group of specialists was represented in search results for concussion care. Conclusions: Nationwide, there is an overall lack of access to multidisciplinary concussion care for pediatric patients. Additionally, those in rural communities face more limitations related to access to facilities with increased distances from closest clinic sites. [ABSTRACT FROM AUTHOR]

Objective: Management of sport-related and recreation-related concussions (SRCs) in children and adolescents is challenging as brain maturation affects prognosis. However, impact seizure was removed as a prognosis modifying factor in children and adolescents with SRCs in the 2017 consensus statement on concussion in sport, based mostly on adult literature. Therefore, this study evaluates the association of impact seizure on the recovery in children and adolescents with SRCs. Design: Retrospective matched case–control study. Setting: Tertiary pediatric sports medicine service, from January 1, 2015, to June 30, 2022. Patients: A cohort of 452 patients, aged 7 to 18 years, with new episode of SRC was seen. From this cohort, 396 patients were included in the analysis, including 22 with impact seizures. Controls were generated using the propensity score matching approach. Patients with moderate or severe traumatic brain injury or incomplete treatment were excluded. Independent Variable: Impact seizure during SRC. Main Outcome Measures: Primary outcome was recovery duration in number of days. Results: The median recovery duration was longer in the cases (73 days, interquartile range [IQR] = 38-143 days) as compared with controls (49.5 days, IQR = 30.5-93.5 days). There was no difference in patients with prolonged recovery (ie >28 days) between both groups (OR 1.6, 95% CI, 0.4-6.6, P = 0.505). Conclusions: Impact seizures prolonged the recovery duration in children and adolescents with SRCs and therefore have a potential concussion modifying prognostic role. These findings could help provide evidence-based management principles for children and adolescents with SRCs in subsequent concussion consensus statements. [ABSTRACT FROM AUTHOR]

Objective: To describe shoulder-related injury rates (IRs), types, severity, mechanisms, and risk factors in youth ice hockey players during games and practices. Design: Secondary analysis of data from a 5-year prospective cohort study, Safe-to-Play (2013-2018). Setting: Canadian youth ice hockey. Participants: Overall, 6584 player-seasons (representing 4417 individual players) participated. During this period, 118 shoulder-related games and 12 practice injuries were reported. Assessment of Risk Factors: An exploratory multivariable mixed-effects Poisson regression model examined the risk factors of body checking policy, weight, biological sex, history of injury in the past 12 months, and level of play. Main Outcome Measures: Injury surveillance data were collected from 2013 to 2018. Injury rates with 95% confidence interval (CI) were estimated using Poisson regression. Results: The shoulder IR was 0.35 injuries/1000 game-hours (95% CI, 0.24-0.49). Two-thirds of game injuries (n = 80, 70%) resulted in.8 days of time-loss, and more than one-third (n = 44, 39%) resulted in >8 days of time-loss. An 83% lower rate of shoulder injury was associated with policy prohibiting body checking compared with leagues allowing body checking (incidence rate ratio [IRR], 0.17; 95% CI, 0.09-0.33). A higher shoulder IR was observed for those who reported any injury in the last 12-months compared with those with no history (IRR, 2.00; 95% CI, 1.33-3.01). Conclusions: Most shoulder injuries resulted in more than 1 week of time-loss. Risk factors for shoulder injury included participation in a body-checking league and recent history of injury. Further study of prevention strategies specific to the shoulder may merit further consideration in ice hockey. [ABSTRACT FROM AUTHOR]

Objective: Previous research, including high-quality systematic reviews, has found that cervical injury, which often accompanies concussive head injury, can delay recovery from concussion. One pilot randomized controlled trial found that focused cervical assessment and appropriate intervention in children and young adults with persisting postconcussive symptoms (PPCS) improved recovery outcomes. Our sports medicine clinics adopted this approach early (within 2 weeks) in children (aged 10-18 years) after concussion. This study describes our clinical management protocol and compares the recovery trajectories in children after concussion with and without a concomitant cervical injury. Design: Prospective cohort study. Setting: Three university-affiliated outpatient sports medicine clinics from September 2016 to December 2019. Patients: One-hundred thirty-four concussed children with cervical impairment (mean age 14.9 years, 65% male, and 6.2 days since concussion) were compared with 130 concussed children without cervical impairment (mean age 14.9 years, 57% male, and 6.0 days since concussion). Independent Variables: Examination findings related to the cervical spine (range of motion, cervical spasm, and cervical tenderness). Main Outcome Measures: Recovery time (measured in days), concussion symptom burden (Postconcussion Symptom Scale), and incidence of PPCS. Results: Children with cervical impairment reported a higher initial symptom burden; however, there were no differences in recovery time (33.65 [28.20-39.09] days vs 35.98 [27.50-44.45] days, P = 0.651) or incidence of PPCS (40.0% vs 34.3%, P = 0.340). Conclusions: We conclude that within this pediatric population, early identification and management of cervical injuries concomitant with concussion may reduce the risk of delayed recovery.

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 FROM AUTHOR]

Objective: To evaluate clinic visits and running-related injury (RRI) characteristics among child and adolescent runners seeking care at an outpatient clinic over a 10-year time frame. Design: Retrospective chart review. Setting: Outpatient hospital-affiliated Injured Runners Clinic. Patients: Children and adolescent runners (6-17 years) with RRIs. Independent Variables: We examined electronic medical records (EMRs) among child and adolescent patients in the hospital database from 2011 to 2021 to obtain RRI characteristics and key demographic factors. Main Outcome Measures: We assessed volume and frequency of patient visits to the clinic by RRI characteristics. Chi square analyses were used to compare the proportion of clinic visits over time and injury trends by body region and diagnosis. Results: There were 392 patients (sex; 277 F; mean age: 16.1 ± 1.3years) and an average of 5 clinic visits per diagnosis (5 ± 4 visits; min: 1 visit, max: 31 visits). Number of visits generally increased over time up to 2016 but declined most drastically during the years of the pandemic (2020-2021; χ² = 644, P < 0 .001). Of the 654 new injury diagnoses, 77.68% were attributed to repetitive stress. Bone stress injuries to the tibia were the most common RRI (χ² = 1940,P < 0.001; N = 132; 20.2% of all injuries) and constituted most of the clinic visits (χ² = 9271, P < 0.001; N = 591; 25.4% of all visits). Conclusion: We identified that adolescents with overuse injuries, particularly bone stress injuries to the tibia, constituted most of the visits to the outpatient healthcare setting. Clinicians should emphasize injury prevention efforts in clinical practice to reduce RRI burden. [ABSTRACT FROM AUTHOR]

Objective: To compare self-reported osteoarthritis of the knee and hip in adults who ran at least 1 marathon as a child with adults who ran high-school cross country (HSCC). Design: Subject self-recall retrospective survey. Setting: Electronic survey. Participants: 319 adults who either ran a marathon under age 18 or ran HSCC recruited from running clubs, marathon participants, and on-line interest groups. Interventions: Survey. Main Outcome Measures: Self-reported history of osteoarthritis (OA), joint pain, anterior cruciate ligament injury, still running or running marathons, and number of marathons as an adult. Results: One hundred twenty-three respondents ran a marathon under age 18 (26% female) and were 40 years old (sd 16) and 196 ran HSCC (53% female) and were 36 years old (sd 13). The mean age of first marathon was 15 (sd 2.3, range 5-17); 50% ran 1 % and 50% ran >1 marathon. Child marathoners reported a family history of OA in knees or hips (26%) or a joint replacement (30%) compared with 24% and 28% of HSCC runners. 10% of child marathoners and 7% of HSCC reported OA and 24% and 21% reported daily or weekly joint pain. 91% of all respondents are still running; 78% of child marathoners (mean 17, range 1-91) and 80% HSCC ran≥1 marathons as adults (mean 10, range 1 -80). Conclusions: Adults who ran marathons as children compared with adults who ran HSCC self-report similar rates of the knee and hip OA, chose to participate of their own accord, continue to run as adults, played other sports, and did not "specialize" in marathons.

Objective: Little is known about the prognostic value of the Buffalo Concussion Treadmill Test (BCTT) after the acute phase of sport-related concussion (SRC). We examined the added prognostic value of the BCTT performed 10 to 21 days after SRC in children, in addition to participant, injury, and clinical process characteristics on days to recovery. Design: Historical clinical cohort study. Setting: Network of approximately 150 Canadian multidisciplinary primary-care clinics. Participants: 855 children (mean age 14 years, range 6-17 years, 44% female) who presented between January 2016, and April 2019 with SRC. Assessment of risk factors: Participant, injury, and clinical process characteristics, with focus on BCTT exercise intolerance assessed 10 to 21 days after injury. Outcome: Days to clinical recovery. Results: Children who were exercise intolerant experienced an increase of 13 days to recovery (95% CI, 9-18 days). Each additional day between SRC and first BCTT was associated with a recovery delay of 1 day (95% CI, 1-2 days), and prior history of concussion was associated with a recovery delay of 3 days (95% CI, 1-5 days). Participant, injury, and clinical process characteristics, and the first attempt BCTT result explained 11% of the variation in recovery time, with 4% accounted for by the BCTT. Conclusion: Exercise-intolerance assessed 10 to 21 days after SRC was associated with delayed recovery. However, this was not a strong prognostic factor for days to recovery. [ABSTRACT FROM AUTHOR]

Objective: To examine patient and injury factors that may predict quality of life (QoL) and symptom duration after concussion. Design: Prospective, longitudinal. Settings: Six children’s hospital-based medical centers and 9 secondary school athletic training facilities. Patients: Pediatric patients (8-18 years) were enrolled as part of the Sport Concussion Outcomes in Pediatrics (SCOPE) study during their initial visit for a diagnosis of sport-related concussion. Interventions: Patients completed a medical history, the Postconcussion Symptom Inventory (PCSI), and Patient-Reported Outcomes Measurement Information System Pediatric Profile-25 (PROMIS-PP). Main Outcome Measures: Eight predictor variables [age, sex, assessment time, loss of consciousness, amnesia and history of concussion, migraines, or attention-deficit hyperactivity disorder or (ADHD)] were assessed using regression models constructed for each dependent variable. Results:A total of 244 patients (15.162.1 years, 41% female) were enrolled (mean 5 5 6 3 days after concussion; range 5 1-14 days). Female sex, later initial assessment, and presence of amnesia were associated with lower QoL scores on several domains, whereas loss of consciousness was associated with higher QoL for fatigue. A history of migraines was associated with lower peer relationship QoL. Patients who subsequently developed persisting symptoms had lower mobility scores and higher anxiety, depressive symptom, fatigue, and pain interference scores. Conclusions: Female sex, later clinic presentation, and amnesia were associated with a lower QoL related to mobility, anxiety, depressive symptoms, fatigue, and pain interference. Interestingly, previous concussion and preinjury ADHD diagnosis did not negatively impact postinjury QoL at the initial visit. Future studies should assess the influence of these factors on QoL at later postinjury time points using a concussion-specific outcomes instrument. [ABSTRACT FROM AUTHOR]

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.

Objective: To examine the association between self-reported and parent-reported attention problems and hyperactivity and rates of injury and concussion in Canadian youth ice hockey players. Design: Secondary analyses of 2 prospective cohort studies. Setting: Canadian youth ice hockey teams. Participants: Ice hockey players (ages 11-17 years) were recruited by team, over 4 seasons (2011-2016). A combined 1709 players contributing 1996 player-seasons were analyzed (257 players participated in more than one season). Assessment of Risk Factors: Data were collected from preseason baseline questionnaires, including child and parent proxy forms of the Behavior Assessment System for Children, second edition. Main Outcome Measures: Injury and concussion rates and incidence rate ratios (IRR) comparing players with and without self-identified or parent-identified attention problems and hyperactivity, adjusted for covariates (ie, body checking policy, previous injury/concussion, and age) and a random effect for team, were estimated using multiple multilevel negative binomial regression. Results: When analyzed continuously, rates of concussion increased with higher self-reported and parent-reported measures of attention problems [IRRSELF = 1.025; 95% confidence interval (CI): 1.011-1.040; IRRPARENT = 1.032; 95% CI: 1.008-1.057]. Self-reported hyperactivity was significantly associated with concussion (IRR = 1.021; 95% CI: 1.007-1.035), but parent-reported hyperactivity was not (IRR = 1.005; 95% CI: 0.983-1.028). A T score ≥ 60 cutoff combining attention problems and hyperactivity scores (an estimate of probable attention-deficit hyperactivity disorder) was not significantly associated with rates of injury or concussion. Conclusions: Attention problems and hyperactivity may place youth ice hockey players at increased risk of concussion and injury. Preseason assessments could identify players for targeted concussion education and risk reduction strategies. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is Available in the Text. Objective: To determine whether slow processing speed is associated with risk of sport-related concussion. Design: We conducted a retrospective cohort study using computerized neurocognitive assessments (Immediate Post-concussion Assessment and Cognitive Testing [ImPACT]) from the Massachusetts Concussion Management Coalition. Slow processing speed was defined as 2 SD below the sample mean (n = 131) and fast processing speed as 2 SD above the sample mean (n = 259). We used a binary logistic regression model to determine the odds of sustaining a concussion with our main predictor being processing speed (high or low) adjusted for the effects of age, sex, and prior number of concussions. Setting: Massachusetts Concussion Management Coalition, Institutional care. Participants: Three hundred ninety junior high soccer players ages 10 to 15 with a baseline score for ImPACT. Independent Variables: Processing Speed. Main Outcome Measures: Risk of sustaining a concussion. Results: Those with slow processing speed had a visual motor composite score of ≤19.92, those with fast-processing speed had a score of ≥46.20. Athletes with slow processing speed were younger (13 vs 14 years; P < 0.001) and more likely to be male (57% vs 49%; P = 0.014). After adjusting for the effects of age, sex, and prior concussions, there was no significant difference in the odds of sustaining a concussion between groups (aOR 1.01; 95% CI, 0.99-1.04). Conclusions: Despite previous research showing that slow processing speed is a risk factor for musculoskeletal injuries during sports, our study suggests that processing speed is not associated with the risk of sustaining a concussion among junior high school soccer players.

This case report highlights a rare type of primary spinal cord tumor, myxopapillary ependymoma, in a pediatric patient who presented to clinic with worsening chronic unilateral thigh pain and neurologic deficits. He was appropriately treated with total gross resection of the tumor and adjuvant radiotherapy and was cleared for competitive sports without any restriction within 1 year of his diagnosis and treatment. Although most musculoskeletal complaints among pediatric patients are of benign etiology, as evidenced by our case, clinicians should have a low threshold to further investigate with advanced imaging modalities should the clinical history and examination be consistent with a more concerning pathologic process.

Objective: The aim of this study was to identify the accuracy of the McMurray test in the adolescent and pediatric population. Design: Retrospective case series. Setting: Tertiary care, institutional. Patients: Inclusion criteria included patients who presented with unilateral knee pain and were seen by pediatric sports medicine physicians. Patients were excluded if their knee pain was related to any underlying conditions. Three hundred patient charts were reviewed, and 183 patients (age range: 8-18 years, mean: 14 years; 74 male) met the inclusion criteria. Interventions: Symptoms at initial visit (knee pain). Main Outcome Measures: Presence of a meniscal tear using the McMurray test. Results: Eighty-four percent (160/191) of patients had a McMurray test documented as performed by the physician, and 17% (27/160) elucidated a positive response. Of 26 patients who had a positive McMurray and underwent magnetic resonance imaging (MRI), 16 (62%) showed a meniscal tear on their MRI. However, of the 87 patients who had a negative McMurray and still underwent MRI, 25 (29%) had a positive meniscal tear. The sensitivity, specificity, positive predictive value, and negative predictive value were 39%, 86%, 62%, and 71%, respectively. Conclusion: In a pediatric and adolescent population, the McMurray test was negative for 61% (23/38) of meniscal tears identified on MRI. Clinical Relevance: Although the test can be a useful tool as a part of a thorough evaluation, combining it with mechanical symptoms, patient history and imaging may be more helpful to diagnose a meniscus tear.

Objective: To explore the prognostic ability of the vestibular/ocular motor screening (VOMS), King–Devick (K-D) Test, and C3 Logix Trails A and B to identify protracted recovery from sports-related concussion (SRC) in patients aged 8 to 12 years. Design: Retrospective cohort analysis. Setting: Specialty pediatric sports concussion clinic. Participants: A total of 114 youth athletes aged 8 to 12 years who were diagnosed with an SRC within 7 days of injury. Independent Variables: A positive screen on the VOMS, K-D, and C3 Logix Trails A and Trails B. Combined positive screens on multiple tests (ie, 2, 3, or all 4 positive screens of 4 possible). Main Outcome Measures: Recovery time in days and protracted recovery (recovery time ≥30-days) were the primary outcomes of interest. Results: A positive VOMS screen was associated with 1.31 greater days to SRC recovery (P = 0.02) than a negative VOMS screen. The K-D and C3 Logix tests were not significantly associated with recovery time, nor were any combinations of tests (P > 0.05). The VOMS demonstrated moderate prognostic ability to predict normal recovery (negative predictive value = 80.78% [95% CI = 63.73-90.95]). Overall predictive accuracy of normal versus protracted recovery was strongest when a participant screened positive on all 4 tests (Accuracy = 76.32% [95% CI = 67.45-83.78]). Conclusions: The VOMS was associated with overall recovery time and proved to be a useful test to identify those who would experience a normal recovery time. Combining the 4 tests improved the prognostic accuracy of the protocol in predicting protracted versus normal recovery. These findings suggest that combining multiple, varied assessments of cognition and vestibular/ocular functions may better explain factors contributing to protracted recovery. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is Available in the Text. Objective: To determine whether high or low adiposity is associated with youth sport-related injury. Data Sources: Ten electronic databases were searched to identify prospective studies examining the association between adiposity [body mass index (BMI) or body fat] and a future time-loss or medical attention sport-related musculoskeletal injury or concussion in youth aged 20 years and younger. Two independent raters assessed the quality (Downs and Black criteria) and risk of bias (Joanna Briggs Institute Critical Appraisal Tool). Random-effects meta-analyses were used to calculate pooled odds ratio [95% confidence interval (CI)] of injury. Main Results: Of 11 424 potentially relevant records, 38 articles were included with 17 eligible for meta-analyses. In qualitative synthesis, no clear association was identified between adiposity and any sport injury; however, 16/22 studies identified high adiposity as a significant risk factor for lower-extremity injury. Meta-analyses revealed higher BMI in youth with any sport-related injury and lower BMI in youth who developed a bone stress injury (BSI) compared with noninjured controls. The pooled OR (95% CI) examining the association of BMI and injury risk (excluding bone injury) was 1.18 (95% CI: 1.03-1.34). A major source of bias in included articles was inconsistent adjustment for age, sex, and physical activity participation. Conclusions: Level 2b evidence suggests that high BMI is associated with greater risk of youth sport injury, particularly lower-extremity injury and excluding BSI or fracture. Although pooled mean differences were low, anthropometric risk of injury seems to be dependent on type and site of injury in youth sport. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is Available in the Text. Objective: To determine whether an association exists between fear of pain and recovery time from sports-related concussion in a pediatric population. Design: Prospective observational study. Setting: Primary outpatient sports medicine clinic of a large pediatric hospital. Patients: One hundred twenty-eight pediatric patients aged 8 to 18 years who presented to clinic with a primary diagnosis of concussion from September 2018 to March 2020. Inclusion criteria included presentation within 2 weeks of injury and symptomatic on initial visit. Patients who sustained a concussion because of motor vehicle collisions or assault were excluded. Independent Variables: There was no intervention. Study participants who met inclusion criteria were administered the Fear of Pain Questionnaire (FOPQ) at their initial visit. Main Outcome Measures: Time to clinical recovery was the main outcome measure and was determined by the fellowship-trained sports medicine physician based on resolution of concussion symptoms, resumption of normal physical and cognitive daily activities, no use of accommodations or medications, and normalization of physical exam. Results: There was a significant difference in FOPQ scores for those with prolonged recovery (M = 33.12, SD = 18.36) compared with those recovering in fewer than 28 days (M = 26.16, SD = 18.44; t [126] = −2.18, P = 0.036). Conclusions: Consistent with the adult literature, we found that pediatric patients are more likely to have a prolonged recovery from concussion when they have higher fear of pain.

Objective: To determine the relationship between patient characteristics and performance on the visio-vestibular examination (VVE) in a cohort of healthy youth athletes and explore the potential association between the VVE and other standardized concussion batteries. Design: Cross-sectional. Setting: Suburban middle and high school. Patients: One hundred ninety subjects age 11 to 18 enrolled before their respective scholastic sport season between August 2017 and March 2020. Assessment of Independent Variables: Patient age, sex, concussion history, comorbidities, hours of weekly exercise, Sport Concussion Assessment Tool, 5th edition (SCAT-5), King–Devick (K–D), Postconcussion Symptom Inventory (PCSI). Main Outcome Measures: Visio-vestibular examination abnormalities (smooth pursuit, horizontal and vertical saccades, horizontal and vertical gaze stability, convergence, right and left monocular accommodation, complex tandem gait). Results: Overall, 29.5% of subjects had at least one of 9 VVE elements abnormal, 7.9% at least 2, and 3.2% at least 3. None of 72 comparisons of the VVE elements, when stratified by age, sex, concussion history, history of headaches, attention deficit hyperactivity disorder, learning issues, psychiatric problems, motion sickness, or weekly hours of exercise, reached significance using the Benjamini–Hochberg procedure at a false discovery rate of 5%. There were no significant associations between VVE elements and the SCAT-5, K–D, or PCSI. Conclusions: The VVE is robust across multiple patient characteristics. Although healthy subjects may have one abnormal element, multiple abnormal elements are a less common feature, making multiple abnormal elements more indicative of concussion, highlighting the use of this assessment in the setting of injury. The VVE tests unique domains when compared with the PCSI, SCAT-5, and K–D. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is Available in the Text. Objective: To describe the frequency with which children are affected by lower-limb apophyseal injuries, and subgroups at greater risk. Design: Systematic review. Setting: N/A. Participants: N/A. Interventions: N/A. Main Outcome Measures: Systematic review of Medline OVID, PsycINFO, Cinahl, and PubMed from inception until February 21st, 2020. Articles reporting prevalence and/or incidence of an apophyseal injury (eg, calcaneal apophysitis) or its eponym (Severs or Sever disease). Per person data relating to the incidence or prevalence. Subgroup comparisons were made between sex groups and between activity participant groups. Results: There was wide variation in measurement approaches and follow-up timeframes with the majority of studies reporting on traction apophysitis of the tibial tubercle (Osgood–Schlatter disease). This condition had a point prevalence of 10% in the general population of children between the ages of 12 and 15 years, whereas the lifetime incidence has been reported as 13%. Point prevalence was higher among those who participated in sport compared with those who did not {relative risk [95% confidence interval (CI): 1.98 (1.31-2.99)]}, whereas lifetime incidence was higher among those who participated in sport at the age of 13 years compared with those who did not [relative risk (95% CI): 4.63 (2.31-9.26)]. Other apophyseal injuries did not report enough data to permit comparisons. Conclusion: Sports participation is likely to substantially increase the frequency of traction apophysitis of the tibial tubercle. Further research is required with standardized approaches to compare frequencies between different apophyseal injuries and subgroups of interest. [ABSTRACT FROM AUTHOR]

Objective: To describe the collaborative findings across a broad array of subspecialties in children and adolescents with postconcussion syndrome (PCS) in a pediatric multidisciplinary concussion clinic (MDCC) setting. Design: Retrospective analysis. Setting: Multidisciplinary concussion clinic at a pediatric tertiary-level hospital. Patients: Fifty-seven patients seen in MDCC for evaluation and management of PCS between June 2014 and January 2016. Interventions: Clinical evaluation by neurology, sports medicine, otolaryngology, optometry, ophthalmology, physical therapy, and psychology. Main Outcome Measures: Specialty-specific clinical findings and specific, treatable diagnoses relevant to PCS symptoms. Results: A wide variety of treatable, specialty-specific diagnoses were identified as potential contributing factors to patients' postconcussion symptoms. The most common treatable diagnoses included binocular vision dysfunction (76%), anxiety, (57.7%), depression (44.2%), new or change in refractive error (21.7%), myofascial pain syndrome (19.2%), and benign paroxysmal positional vertigo (17.5%). Conclusions: Patients seen in a MDCC setting receive a high number of treatable diagnoses that are potentially related to patients' PCS symptoms. The MDCC approach may (1) increase access to interventions for PCS-related impairments, such as visual rehabilitation, physical therapy, and psychological counseling; (2) provide patients with coordinated medical care across specialties; and (3) hasten recovery from PCS.

Objectives: Examine sociodemographic differences (gender, age, and language spoken at home) on baseline Child Sport Concussion Assessment Tool 5th Edition (Child SCAT5) scores and establish normative reference data for the Child SCAT5 among middle school student athletes. Design: Cross-sectional study. Setting: Nine middle schools in Virginia. Participants: A sample of 1355 athletes playing competitive school-sponsored sports (ages 11-13, M = 12.3 +/- 0.8; 40.1% girls, 59.9% boys) during the 2017 and 2018 school year. Certified athletic trainers administered the Child SCAT5 within the first 2 weeks of the sport season. Independent Variables: Self-reported gender, age, and language spoken at home. Main Outcome Measures: All Child SCAT5 outcome measures. Results: Gender, age, and language spoken at home were associated with Child SCAT5 scores, but the magnitude of differences was generally small. Specifically, girls endorsed more symptoms (girls: M = 8.4 +/- 5.7, boys: M = 7.5 +/- 5.7; P = 0.003) and greater symptom severity (girls: M = 11.6 +/- 9.4, boys: M = 10.4 +/- 9.3; P = 0.006) than boys and performed slightly better than boys on cognitive and balance tasks. Older students performed slightly better than younger students on tests of cognition (eg, SAC-C: 11-year-olds: M = 21.3 +/- 2.1, 13-year-olds: M = 21.7 +/- 2.1; P = 0.02). Total symptoms (P = 0.01), symptom severity (P = 0.01), immediate memory (P < 0.001), delayed recall (P = 0.001), and SAC-C total scores (P = 0.002) differed across language groups. Conclusions: Gender, age, and language spoken in the home are associated with baseline scores on multiple components of the Child SCAT5 among middle school students, although the magnitudes of observed differences are small. Normative reference values are provided for clinicians when interpreting Child SCAT5 scores. [ABSTRACT FROM AUTHOR]

Objective: To describe the epidemiology of sledding-related injuries among children and adults treated in US emergency departments (EDs). Design: The researchers performed a retrospective analysis using data from the National Electronic Injury Surveillance System (NEISS). Setting: The NEISS collects data on consumer products-related and sports-related injuries treated in US EDs from approximately 100 hospitals that represent a probability sample of >5000 hospitals. Patients: Children (≤19 years of age) and adults who were treated for sledding-related injuries in EDs from 2008 to 2017. Independent Variables: The researchers analyzed characteristics that included sex, body part injured, injury diagnosis, disposition from the ED, injury locale, injury mechanism, and sled type. Main Outcome Measures: All cases of sledding-related injuries were identified using NEISS product codes for sleds (1217), toboggans (1273), snow disks (1274), and snow tubes (1299). Results: An estimated 220 488 patients [95% confidence interval (CI): 169 839-271 137] were treated in EDs for sledding-related injuries. Overall, the injury rate decreased significantly for both children and adults. Children accounted for 69.7% of the injury cases. Fractures were the most common injury diagnosis for children (23.9%) and adults (27.4%). Compared to adults, children were more likely to sustain a head injury [relative risk (RR): 1.91 (95% CI: 1.73-2.13)] and be diagnosed with a concussion or closed-head injury (CHI) [RR: 1.58 (95% CI: 1.35-1.84)]. Most patients were injured by a collision (63.2%). Snow tube and disk riders were more likely to sustain a concussion or CHI compared to sled and toboggan riders [RR: 1.53 (95% CI: 1.18-1.99)]. Injuries predominantly occurred when patients collided with objects in the environment (47.2%). Conclusions: Although sledding-related injuries decreased over the study period, more research and education to prevent these injuries is needed. The injury patterns and risk of injury type differed by age, with more head injuries sustained by children. Sledding should be performed in obstacle-free areas to reduce the risk of collision and while wearing helmets to mitigate head injuries. [ABSTRACT FROM AUTHOR]

Supplemental Digital Content is Available in the Text. Objective: The need to have a pediatric-specific concussion management protocol on Return to School (RTS) and Return to Activity (RTA) after concussion has been recognized internationally. The first step to evaluate the protocol effectiveness is to establish whether children and youth are adhering to these recommendations. The objective of this study was to explore the prevalence and predictors of adherence to RTS and RTA concussion management protocols for children/youth. Design: A prospective cohort of children/youth with concussion. Setting: Childhood Disability Research Centre. Participants: One hundred thirty-nine children/youth aged 5 to 18 years, diagnosed with concussion and symptomatic upon enrollment, were followed for up to 6 months. Primary recruitment occurred from a Children's Hospital Emergency Department. Intervention: Provision of RTS/RTA guidelines. Main Outcome Measures: Measurement of adherence came from multiple sources, including the child's and parent's knowledge of protocols, research personnel evaluations, and self-reported stages of RTS/RTA and Post-Concussion Symptom Scale (PCSS) scores. Results: Spearman correlations and logistic regression were used, investigating the relationship between PCSS and progression of protocols and determining predictors of adherence. Significant negative associations between total PCSS score and stage of RTS/RTA protocols were found. Fifty-three percent and 56% of the participants adhered to the RTS and RTA protocols, respectively. Conclusions: Children's knowledge of protocols and total PCSS scores significantly predicted adherence to RTS/RTA and may be the most important factors in predicting adherence during recovery from concussion.
