Reduced Concussion Symptom Burden in Early Adolescent Athletes Using a Head-Neck Cooling Device.

OBJECTIVE: To determine whether an investigational head-neck cooling device, Pro2cool, can better reduce symptom severity compared with standard postconcussion care in early adolescent athletes after a sports-related concussion. DESIGN: Prospective, longitudinal, randomized trial design conducted over a 28-day period. SETTING: Six pediatric medical centers in Ohio and Michigan. PARTICIPANTS: The study enrolled 167 male and female 12- to 19-year-old athletes who experienced a sports-related concussion within 8 days of study enrollment and registering a Sports Concussion Assessment Tool 5 (SCAT5) composite score >7. INTERVENTIONS: Pro2cool, an investigational head-neck cooling therapy device, was applied at 2 postinjury time points compared with postconcussion standard of care only. MAIN OUTCOME MEASURES: Baseline SCAT5 composite symptom severity scores were determined for all subjects. Sports Concussion Assessment Tool 5 scores for concussed athletes receiving cooling treatment were analyzed across 6 independent postenrollment time points compared with subjects who did not receive cooling therapy and only standard care. Adverse reactions and participate demographics were also compared. RESULTS: Athletes who received Pro2cool cooling therapy (n = 79) experienced a 14.4% greater reduction in SCAT5 symptom severity scores at the initial visit posttreatment, a 25.5% greater reduction at the 72-hour visit posttreatment, and a 3.4% greater reduction at the 10-day visit compared with subjects receiving only standard care (n = 88). Overall, 36 adverse events (increased blood pressure, decreased pulse, and dizziness) were reported, with 13 events associated with the device, of which 3 were classified as moderate in severity. CONCLUSIONS: This study demonstrates the efficacy and safety of head and neck cooling for the management of concussion symptoms in adolescent athletes of an age group for which little to no prior data are available.

Athletes With Attention-Deficit/Hyperactivity Disorder: Position Statement of the American Medical Society for Sports Medicine.

ABSTRACT: Athletes of all ages may be affected by medical and mental health issues. Sports medicine physicians should be familiar with common conditions that may affect the well-being of athletes, such as attention-deficit/hyperactivity disorder (ADHD). ADHD behaviors have the potential to affect a person's ability to concentrate. It is likely that social and cognitive therapies combined with pharmacotherapy will be the most effective way to treat ADHD in athletes. Medications used for ADHD, especially stimulant types, are known to improve alertness, reaction time, anaerobic performance, and endurance, which would potentially improve athletic performance. Furthermore, stimulant medications may enable student athletes with ADHD to focus on academic studies for longer periods of time, beyond usual levels of fatigue, important for those who may be exhausted after practices and games. The purported performance enhancement effects and potential adverse effects of stimulant medications have prompted many sports governing bodies to ban prescription stimulants or establish strict rules for their use. Athletes taking physician-prescribed stimulants to treat ADHD need to provide the appropriate documentation for approval before competition or risk punitive measures. Physicians should strive to provide a high quality of care to athletes with ADHD through early diagnosis, appropriate and careful multidisciplinary treatment, and complete and timely documentation to facilitate continued sports participation.

An intervention to improve knowledge and increase comfort of concussion management among school medical staff.

BACKGROUND: Concussion can negatively impact a child's ability to learn. School-based health professional staff have a unique opportunity to monitor students during recovery and mitigate the potential negative impact. Little is known about school health professional staff's knowledge and comfort with concussion diagnosis and management. OBJECTIVES: We aimed to evaluate whether a tailored concussion education session could improve school health professional staff's knowledge about pediatric concussions. A secondary aim was to determine their knowledge retention and comfort with concussion management over the following year, including the impact of periodic follow-up education. We hypothesized that there would be sustained improvement in concussion knowledge and self-reported comfort in concussion management. STUDY DESIGN: This study was a pre/post-intervention assessment with longitudinal follow-up. The study investigators provided a three-hour educational presentation about concussions in school-aged children. A survey on knowledge and management of pediatric concussions was administered immediately before and after this educational intervention. Knowledge retention and comfort with management was assessed at six months and at one year post-intervention. PARTICIPANTS AND SETTING: Participants included Cincinnati Health Department school health professional staff in attendance at their Back to School in-service, prior to the start of the 2017-2018 school year. RESULTS: Sixty school health professional staff from thirty-three schools completed the baseline knowledge survey, and forty completed all four assessments. Among the 40 participants with complete data, on average, the correct response rate (mean number correct, SD) was 82.3% (18.1/22, 11.0) pre-education, 91.8% (20.2/22, 10.3) immediate post-education, 86.4% (19.0/22, 10.8) 6-month follow-up, and 87.3% (19.2/22, 10.9) one-year follow-up. CONCLUSIONS: A brief didactic educational intervention improved pediatric concussion knowledge and management skills among school health care providers. Periodic and in-person education is likely necessary to optimize knowledge retention.

Does central nervous system dysfunction underlie patellofemoral pain in young females? Examining brain functional connectivity in association with patient-reported outcomes.

Patellofemoral pain (PFP) is defined as retro- or peri-patellar knee pain without a clear structural abnormality. Unfortunately, many current treatment approaches fail to provide long-term pain relief, potentially due to an incomplete understanding of pain-disrupted sensorimotor dysfunction within the central nervous system. The purposes of this study were to evaluate brain functional connectivity in participants with and without PFP, and to determine the relationship between altered brain functional connectivity in association with patient-reported outcomes. Young female patients with PFP (n = 15; 14.3 ± 3.2 years) completed resting-state functional magnetic resonance imaging (rs-fMRI) and patient-reported outcome measures. Each patient with PFP was matched with two controls (n = 30, 15.5 ± 1.4 years) who also completed identical rs-fMRI testing. Six bilateral seeds important for pain and sensorimotor control were created, and seed-to-voxel analyses were conducted to compare functional connectivity between the two groups, as well as to determine the relationship between connectivity alterations and patient-reported outcomes. Relative to controls, patients with PFP exhibited altered functional connectivity between regions important for pain, psychological functioning, and sensorimotor control, and the connectivity alterations were related to perceived disability, dysfunction, and kinesiophobia. The present results support emergent evidence that PFP is not localized to structural knee dysfunction, but may actually be resultant to altered central neural processes. Clinical significance: These data provide potential neuro-therapeutic targets for novel therapies aimed to reorganize neural processes, improve neuromuscular function, and restore an active pain-free lifestyle in young females with PFP.

High School Sports-Related Concussion and the Effect of a Jugular Vein Compression Collar: A Prospective Longitudinal Investigation of Neuroimaging and Neurofunctional Outcomes.

Sports-related concussion (SRC) can exert serious acute and long-term consequences on brain microstructure, function, and behavioral outcomes. We aimed to quantify the alterations in white matter (WM) microstructure and global network organization, and the decrements in behavioral and cognitive outcomes from pre-season to post-concussion in youth athletes who experienced SRC. We also aimed to evaluate whether wearing a jugular compression neck collar, a device designed to mitigate brain "slosh" injury, would mitigate the pre-season to post-concussion alterations in neuroimaging, behavioral, and cognitive outcomes. A total of 488 high school football and soccer athletes (14-18 years old) were prospectively enrolled and assigned to the non-collar group (n = 237) or the collar group (n = 251). The outcomes of the study were the pre-season to post-concussion neuroimaging, behavioral, and cognitive alterations. Forty-six participants (non-collar: n = 24; collar: n = 22) were diagnosed with a SRC during the season. Forty of these 46 athletes (non-collar: n = 20; collar: n = 20) completed neuroimaging assessment. Significant pre-season to post-concussion alterations in WM microstructural integrity and brain network organization were found in these athletes (corrected p < 0.05). The alterations were significantly reduced in collar-wearing athletes compared to non-collar-wearing athletes (corrected p < 0.05). Concussion and collar main effects were identified for some of the behavioral and cognitive outcomes, but no collar by SRC interaction effects were observed in any outcomes. In summary, young athletes exhibited significant WM microstructural and network organizational, and cognitive alterations following SRC. The use of the jugular vein compression collar showed promising evidence to reduce these alterations in high school contact sport athletes.

Musculoskeletal and Sports Medicine Curriculum Guidelines for Pediatric Residents.

ABSTRACT: Musculoskeletal (MSK) and sports-related conditions are relatively common in the pediatric population. Pediatric residencies should provide residents with the knowledge and skills to assess and manage both acute and chronic MSK and sports injuries and complaints. Residents should develop the competencies and attitudes to safeguard and promote a healthy and active lifestyle for youth. Programs can use a variety of educational tools, both in the clinic and on the field, to provide a well-rounded MSK curriculum throughout the residency years. This article provides a review of general pediatric sports medicine curriculum guidelines and suggested implementation strategies.

Attention-Deficit/Hyperactivity Disorder Status and Sex Moderate Mild Traumatic Brain Injury Symptom Severity in Children and Adolescents: Implications for Clinical Management.

OBJECTIVE: To investigate the impact of pediatric mild traumatic brain injury (mTBI), using a broad parent-reported measure, and to determine whether parent-ratings of mTBI symptoms are higher among those with premorbid attention-deficit/hyperactivity disorder (ADHD) and females. DESIGN: Retrospective case-control. SETTING: Hospital-based sports medicine clinic. PARTICIPANTS: The retrospective chart review included 1346 (age: M = 13.11 years, SD = 2.6; 61.7% male) pediatric patients with (n = 209) and without (n = 1137) ADHD. INDEPENDENT VARIABLES: Group membership (ADHD vs non-ADHD) and sex (male vs female). MAIN OUTCOME MEASURES: Baseline and current Post-Concussion Symptom Inventory-Parent Report Form (PCSI-P) Physical, Emotional, Cognitive, and Fatigue subscale scores. This study used a retrospective chart review; therefore, the hypotheses reported for the current study were formed after data were collected. RESULTS: Controlling for patient age and days from mTBI, patients with ADHD had significantly higher retrospective parent-reported pre-mTBI ratings of physical, emotional, and cognitive symptoms (ds = 0.17-0.62) and higher post-mTBI ratings across all 4 symptom domains (ds = 0.18-0.57) than those without ADHD. There was no group × time interaction for any of the PCSI-P subscales. Females overall had higher retrospective parent-reported pre-injury Fatigue and Emotional symptoms (ds = 0.13-0.19) and higher post-mTBI symptoms in all 4 PCSI-P symptom domains (ds = 0.23-0.35), relative to males. CONCLUSIONS: Attention-deficit/hyperactivity disorder-related postinjury exacerbations in parent-reported symptoms can be explained, in part, by elevated retrospective parent-reported ADHD-related pre-mTBI ratings. These results highlight the importance of assessing a patient's baseline symptoms post-mTBI. These data also indicate that ADHD status and sex should be considered when interpreting mTBI symptom severity during clinical evaluation of concussion.

The effects of internal jugular vein compression for modulating and preserving white matter following a season of American tackle football: A prospective longitudinal evaluation of differential head impact exposure.

The purpose of this clinical trial was to examine whether internal jugular vein compression (JVC)-using an externally worn neck collar-modulated the relationships between differential head impact exposure levels and pre- to postseason changes in diffusion tensor imaging (DTI)-derived diffusivity and anisotropy metrics of white matter following a season of American tackle football. Male high-school athletes (n = 284) were prospectively assigned to a non-collar group or a collar group. Magnetic resonance imaging data were collected from participants pre- and postseason and head impact exposure was monitored by accelerometers during every practice and game throughout the competitive season. Athletes' accumulated head impact exposure was systematically thresholded based on the frequency of impacts of progressively higher magnitudes (10 g intervals between 20 to 150 g) and modeled with pre- to postseason changes in DTI measures of white matter as a function of JVC neck collar wear. The findings revealed that the JVC neck collar modulated the relationships between greater high-magnitude head impact exposure (110 to 140 g) and longitudinal changes to white matter, with each group showing associations that varied in directionality. Results also revealed that the JVC neck collar group partially preserved longitudinal changes in DTI metrics. Collectively, these data indicate that a JVC neck collar can provide a mechanistic response to the diffusion and anisotropic properties of brain white matter following the highly diverse exposure to repetitive head impacts in American tackle football. Clinicaltrials.gov: NCT# 04068883.

Youth sports participation and health status in early adulthood: A 12-year follow-up.

Examining association between serial participation in youth organized sports (OS) and concurrent cardiometabolic risk factors, with long-term health status, will aid understanding the role of OS participation. Combining data from a prospective study and a follow-up survey, we aimed to determine association between youth OS participation and cardiometabolic risk factors with health and physical activity (PA) in young adulthood. Cardiometabolic risk factors were monitored yearly, and OS involvement through middle school, high school, and college, together with current status was recorded 12 years after the initial study began; 462 participants completed follow-up. Cardiometabolic risk factors included: body mass index (BMI), waist circumference, blood pressure, total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL) cholesterol and triglycerides, fasting glucose and insulin. Participants continuing OS participation from middle to high school and/or college had significantly lower BMI/BMI z-scores [24.7 vs 27.4 (p < 0.05) and 0.51 vs 0.82 (p < 0.05), respectively] and significantly higher HDL [48.7 vs 45.4 (p ≤ 0.05)] than those without OS participation after middle school. Waist circumference of females was significantly smaller in those who participated in OS from middle to high school and/or college (84.9 cm) compared to those who had no OS (92.1 cm), (p < 0.05). Participants continuing OS from middle to high school and/or college reported significantly higher follow-up PA levels than those who had no OS after middle school (p < 0.001). This study provides novel data showing serial participation in OS from middle to high school and/or college was associated with a superior cardiometabolic health profile in school and increased PA levels at 12-year follow-up.

Altered Functional and Structural Connectomes in Female High School Soccer Athletes After a Season of Head Impact Exposure and the Effect of a Novel Collar.

Background: Characterization of, and evaluation of strategies to mitigate, the effects of sub-concussive impacts (SCI) on brain structure and function are crucial to understanding potential long-term neurological risks associated with sports participation. Objectives: To evaluate the efficacy of a jugular vein compression collar for preserving functional and structural measures of brain network organization in a cohort of female high school soccer players throughout a season of competitive play. Methods: Athletes were assigned to a collar (N = 72) or non-collar (N = 56) group before engaging in a season of play, during which head impact data were recorded via accelerometer for every practice and competition. Participants completed neuroimaging sessions before and following the season. A graph theoretical framework was applied to the functional and structural connectivity measures computed from resting state functional magnetic resonance imaging (rs-fMRI) and diffusion tensor imaging (DTI) data. Results: Non-collar-wearing athletes exhibited significantly increased rs-fMRI-derived global clustering coefficients (p = 0.032) and DTI-derived modularity (p = 0.042), compared to collar-wearing athletes. No longitudinal changes in any graph measures were observed for the collar group (p > 0.05). Conclusion: The observed increase in graph measures in the non-collar group is congruent with previous studies of SCI and is similar to graph theoretical studies of traumatic brain injury. The absence of alterations in graph metrics in the collar group indicates a potential ameliorating effect of the collar device against network reorganization, in line with previous literature.

Identifiable Factors Associated With Acceptance Into Sports Medicine Fellowship Programs: A Brief Report.

OBJECTIVE: To identify factors associated with entry into primary care sports medicine (PCSM) fellowship programs. DESIGN: Primary care sports medicine fellowship directors (FDs) and fellowship faculty were surveyed regarding preferences for accepting applicants into their programs. SETTING: Survey study. PARTICIPANTS: Primary care sports medicine FDs and fellowship faculty. ASSESSMENT OF RISK FACTORS: Questions were designed to delineate factors [clinical experience, letters of recommendation (LOR), scholarship, service commitment, interview performance, etc] perceived to be associated with entry into PCSM fellowship (1-10 scale; 10 = highest value). Weighted mean ± SD were calculated for each question. MAIN OUTCOME MEASURES: Determination of most valued factors for entry into PCSM fellowship. RESULTS: Responses were provided by 242/2332 (10.4%) of the American Medical Society for Sports Medicine members, including 77 of 175 (44%) FDs. The top 3 factors for entry into PCSM fellowships for all respondents were as follows: interview performance (9.17 ± 1.13), LOR from SM fellowship faculty (8.20 ± 1.67), and high school game/event coverage (7.83 ± 1.70). Musculoskeletal ultrasound experience (4.50 ± 2.23) and residency training in pediatrics (4.58 ± 2.54), internal medicine (4.48 ± 2.44), emergency medicine (4.44 ± 2.59), and physical medicine and rehabilitation (4.40 ± 2.83) received the lowest scores. CONCLUSIONS: Applicants seeking entry into SM fellowships should prioritize performance during interviews, LOR from SM fellowship faculty, and team game/event coverage experiences.

Performance Times for the King-Devick Test in Children and Adolescents.

OBJECTIVE: To establish the King-Devick test (KD) performance values for children and adolescents. DESIGN: Prospective cohort. SETTING: Pediatric sports medicine clinics. PARTICIPANTS: Five hundred seven athletes presenting to a pediatric sports medicine clinic for non-concussion-related evaluations. INDEPENDENT VARIABLES: Age, sex, and risk factors for abnormal concussion recovery. MAIN OUTCOME MEASURES: The King-Devick test time. RESULTS: Four hundred eighty-three participants were included in the final analysis, which included 60.5% girls (n = 292) and 39.5% boys (n = 191). The KD test performance varied by age with a steady decrease in test time yearly from 8 years through 14 years of age, where some plateauing occurred. Baseline scores changed approximately 31 seconds over ages 8 to 18. Analysis of variance results revealed a strong effect of age on overall mean KD time (P < 0.001). The KD test performance was not associated with sex or other studied concussion risk factors or comorbid conditions. CONCLUSIONS: The KD test performance was reported in a cohort of youth aged 8 to 18 years, allowing for comparison of performance in individuals who may not have a baseline assessment. If baseline testing is desired, at least yearly intervals seems to be appropriate through childhood and early adolescence.

Organized Sports for Children, Preadolescents, and Adolescents.

Interest and participation in organized sports for children, preadolescents, and adolescents continue to grow. Because of increased participation, and younger entry age, in organized sports, appropriate practice, game schedules, and content become more important, taking into account athlete developmental stage and skills. Parental support for organized sports in general, with focus on development and fun instead of winning, has emerged as a key factor in the athlete's enjoyment of sports. Schools and community sports organizations who support multiple levels of sport (eg, recreational, competitive, elite) can include more youth who want to play sports and combat sport dropout. This report reviews the benefits and risks of organized sports as well as the roles of schools, community organizations, parents, and coaches in organized sports. It is designed to complement the American Academy of Pediatrics clinical reports "Physical Activity Assessment and Counseling in Pediatric Clinical Settings" and "Sports Specialization and Intensive Training in Young Athletes" by reviewing relevant literature on healthy organized sports for youth and providing guidance on organized sport readiness and entry. The report also provides guidance for pediatricians on counseling parents and advocating for healthy organized sports participation.

Mild Jugular Compression Collar Ameliorated Changes in Brain Activation of Working Memory after One Soccer Season in Female High School Athletes.

Recent neuroimaging studies have suggested that repetitive subconcussive head impacts, even after only one sport season, may lead to pre- to post-season structural and functional alterations in male high school football athletes. However, data on female athletes are limited. In the current investigation, we aimed to (1) assess the longitudinal pre- to post-season changes in functional MRI (fMRI) of working memory and working memory performance, (2) quantify the association between the pre- to post-season change in fMRI of working memory and the exposure to head impact and working memory performance, and (3) assess whether wearing a neck collar designed to reduce intracranial slosh via mild compression of the jugular veins can ameliorate the changes in fMRI brain activation observed in the female high school athletes who did not wear collars after a full soccer season. A total of 48 female high school soccer athletes (age range: 14.00-17.97 years) were included in the study. These athletes were assigned to the non-collar group (n = 21) or to the collar group (n = 27). All athletes undewent MRI at both pre-season and post-season. In each session, a fMRI verbal N-Back task was used to engage working memory. A significant pre- to post-season increase in fMRI blood oxygen level dependent (BOLD) signal was demonstrated when performing the N-back working memory task in the non-collar group but not in the collar group, despite the comparable exposure to head impacts during the season between the two groups. The collar group demonstrated significantly smaller pre- to post-season change in fMRI BOLD signal than the non-collar group, suggesting a potential protective effect from the collar device. Significant correlations were also found between the pre- to post-season increase in fMRI brain activation and the decrease in task accuracy in the non-collar group, indicating an association between the compensatory mechanism in underlying neurophysiology and the alteration in the behavioral outcomes.

Symptom-Guided Emergency Department Discharge Instructions for Children With Concussion.

OBJECTIVES: The objective was to evaluate the use and utility of a novel set of emergency department discharge instructions (DIs) for concussion based on a child's ongoing symptoms: symptom-guided DIs (symptom DIs). Differences in clinical outcomes were also assessed. METHODS: A convenience sample of 114 children aged 7 to 17 years presenting to an urban pediatric emergency department with a complaint of concussion was assembled. Children were randomized to standard DIs or symptom DIs. Children completed a graded symptom checklist (GSC) and completed daily the GSC for 1 week. Telephone follow-up was performed at 7 days after enrollment using a standardized survey. RESULTS: Fifty-eight children received the symptom DIs, and 56 received the standard DIs. Rates of use were similar with reported rates of 92% for symptom DIs and 84% for standard DIs. Caregivers with symptom DIs reported that the DIs were more helpful in determining when their child could return to school and physical activity (P < 0.05) than caregivers with standard DIs. Children continued to have postconcussive symptoms days and weeks after their injury with 44% of children with symptom DIs and 51% of children with standard DIs reporting symptoms on the GSC at 1 week. CONCLUSIONS: Both study groups reported frequent use of the DIs. Caregivers with symptom DIs found them particularly helpful in determining when their child could return to school and physical activity. Larger-scale investigations are needed to further develop instructions that are easy to use and that may decrease the postconcussive period.

Reducing concussion symptoms among teenage youth: Evaluation of a mobile health app.

OBJECTIVE: To evaluate whether a mobile health application that employs elements of social game design could compliment medical care for unresolved concussion symptoms. DESIGN: Phase I and Phase II (open-label, non-randomized, ecological momentary assessment methodology). SETTING: Outpatient concussion clinic. PARTICIPANTS: Youth, aged 13-18 years, with concussion symptoms 3+ weeks after injury; Phase I: n = 20; Phase II: n = 19. INTERVENTIONS: Participants received standard of care for concussion. The experimental group also used a mobile health application as a gamified symptoms journal. OUTCOME MEASURES: Phase I: feasibility and satisfaction with intervention (7-point Likert scale, 1 high). Phase II: change in SCAT-3 concussion symptoms (primary), depression and optimism. RESULTS: Phase 1: A plurality of participants completed the intervention (14 of 20) with high use (110 +/- 18% play) and satisfaction (median +/- interquartile range (IQR) = 2.0+/- 0.0). Phase II: Groups were equivalent on baseline symptoms, intervention duration, gender distribution, days since injury and medication prescription. Symptoms and optimism improved more for the experimental than for the active control cohort (U = 18.5, p = 0.028, effect size r = 0.50 and U = 18.5, p = 0.028, effect size r = 0.51, respectively). CONCLUSIONS: Mobile apps incorporating social game mechanics and a heroic narrative may promote health management among teenagers with unresolved concussion symptoms.

Current state of concussion prevention strategies: a systematic review and meta-analysis of prospective, controlled studies.

OBJECTIVE: The aim of the current review was to systematically identify, evaluate and synthesise trials that examine concussion prevention via equipment, educational programmes and training programmes. DATA SOURCES: PubMed and EBSCO host (CINAHL, MEDLINE, SPORTDiscus). ELIGIBILITY CRITERIA FOR SELECTING STUDIES: The electronic databases PubMed and EBSCO were searched using the phrases: concussion prevention equipment, concussion prevention training and concussion prevention education. Included studies utilised a prospective study design to evaluate the preventative effect of: (1) equipment, (2) training or (3) educational programmes on the incidence of concussions in comparison to a control group. DATA EXTRACTION: Demographic data and intervention methods were recorded. Intervention and control group concussion rates and superficial head injury rates were extracted and combined using random-effects relative risk meta-analysis. RESULTS: 14 studies evaluated interventions of novel protective equipment. One prospective investigation evaluated an educational programme. The relative risk of concussion for participants enrolled in the interventional arms of trials was not significantly different from that in standard practice arms (RR=0.78, 95% CI 0.55 to 1.11, χ2=1.8, p=0.17; I2=85.3%, 95% CI 71.5% to 90.8%). The relative risk of concussion for participants wearing protective equipment (ie, headgear, full face shields) relative to their counterparts wearing standard or no equipment, calculated from seven available reports, showed no effect of intervention (RR=0.82, 95% CI 0.56 to 1.20, χ2=1.06, p=0.30; I2=86.7%, 95% CI 73.3% to 91.8%). The relative risk of superficial head injury for participants wearing protective equipment relative to their counterparts, calculated from three reports, showed a significant risk reduction (RR=0.41, 95% CI 0.31 to 0.56, χ2=34.13, p<0.0001; I2=53.1%, 95% CI 0% to 85.2%). CONCLUSIONS: Prospective controlled studies indicate that certain protective equipment may prevent superficial head injury, but these items are suboptimal for concussion prevention in sport.

Is current medical education adequately preparing future physicians to manage concussion: an initial evaluation.

OBJECTIVES: In 2010, there were 2.5 million hospitalizations, emergency room visits, or deaths associated with concussions in the United States.[1] Knowledge deficits exist among physicians regarding concussion management, which can lead to severe repercussions, including poor patient outcomes, poor patient satisfaction, and potential medical-legal issues. While concussion is a prevalent condition evaluated in the medical field, medical students continue to have a knowledge deficit regarding concussion diagnosis, prognosis, medical management, and return to play guidelines. METHODS: Medical students from a mid-western medical school completed a survey on concussion diagnosis, prognosis, medical management, and return to play guidelines. RESULTS: The response rate was 40%. The data suggests that the vast majority of medical students are able to define concussion; however, most reported never having a lecture dedicated to concussion during medical school and also lacked clinical experience with acute concussion and post-concussive syndrome. There are clear areas of deficiency as noted by the inability of students to correctly identify symptoms and appropriate management of concussion. CONCLUSION: The current study indicates that at an individual, mid-western, top 50 medical school, current medical trainees may not be adequately educated to identify and manage concussion. Future research is warranted to determine the optimal guidelines to educate future physicians as it pertains to concussion diagnosis, management, prognosis, and return to play guidelines.
