Importance of 'Return-to-Learn' in Pediatric and Adolescent Concussion.

The concept of “return-to-play” after concussion is familiar to pediatricians who routinely care for injured student-athletes. Premature return-to-play of a student-athlete who is still injured from a concussion may result in more severe and potentially long-lasting deficits.1 In contrast, “return-to-learn” plans for student-athletes have not received as much attention, perhaps because so much regarding concussion awareness comes from lay reports of professional athletes who play a sport for their livelihood, as compared with pediatric and adolescent-aged athletes for whom school is their primary “work.” Importance of ‘Return-to-Learn’ in Pediatric and Adolescent Concussion

Pediatric Providers’ Self-Reported Knowledge, Practices, and Attitudes About Concussion

OBJECTIVE: To determine the self-reported practices and attitudes surrounding concussion diagnosis and management in a single, large pediatric care network. METHODS: A cross-sectional survey was distributed to pediatric primary care and emergency medicine providers in a single, large pediatric care network. For all survey participants, practices and attitudes about concussion diagnosis and treatment were queried. RESULTS: There were 145 responses from 276 eligible providers, resulting in a 53% response rate, of which 91% (95% confidence interval [CI]: 86%–95%) had cared for at least 1 concussion patient in the previous 3 months. A Likert scale from 1 “not a barrier” to 5 “significant barrier” was used to assess providers’ barriers to educating families about the diagnosis of concussion. Providers selected 4 or 5 on the scale for the following barriers and frequencies: inadequate training to educate 16% (95% CI: 11%–23%), inadequate time to educate 15% (95% CI: 12%–24%), and not my role to educate 1% (95% CI: 0.4%–5%). Ninety-six percent (95% CI: 91%–98%) of providers without a provider decision support tool (such as a clinical pathway or protocol) specific to concussion, and 100% (95% CI: 94%–100%) of providers without discharge instructions specific to concussion believed these resources would be helpful. CONCLUSIONS: Although pediatric primary care and emergency medicine providers regularly care for concussion patients, they may not have adequate training or infrastructure to systematically diagnose and manage these patients. Specific provider education, decision support tools, and patient information could help enhance and standardize concussion management.

Concussion in the Adolescent Athlete

Concussion in the adolescent athlete is a common sports and recreation injury. Traditional management of concussion in this age group has focused on sport return-to-play decisions. However, new research on mild traumatic brain injury has dramatically changed the management of concussion. During the acute healing phase, physical and cognitive rest are crucial for healing. In the school-aged athlete, new concepts, such as complete brain rest, have made school management decisions as important as sport return-to-play decisions. Despite tremendous improvements in the understanding of concussion, most of the research has been done in young adults. The lack of prospective studies in early adolescent student athletes limits definitive management recommendations. This article reviews the current understanding of the epidemiology, pathophysiology, and clinical presentation of concussion and discusses the unique factors involved in clinical management of concussion in the adolescent student-athlete.

Vision Diagnoses Are Common After Concussion in Adolescents

Objective. To determine the prevalence of vision diagnoses after concussion in adolescents. Methods. Cross-sectional study from July 1, 2013 to February 28, 2014, of patients aged 11 to 17 years with concussion evaluated in a comprehensive concussion program. Results. A total of 100 adolescents were examined, with a mean age of 14.5 years. Overall, 69% had one or more of the following vision diagnoses: accommodative disorders (51%), convergence insufficiency (49%), and saccadic dysfunction (29%). In all, 46% of patients had more than one vision diagnosis. Conclusions. A high prevalence of vision diagnoses (accommodative, binocular convergence, and saccadic eye movement disorders) was found in this sample of adolescents with concussion, with some manifesting more than one vision diagnosis. These data indicate that a comprehensive visual examination may be helpful in the evaluation of a subset of adolescents with concussion. Academic accommodations for students with concussion returning to the classroom setting should account for these vision diagnoses.

Characteristics of Prolonged Concussion Recovery in a Pediatric Subspecialty Referral Population

OBJECTIVE To identify pre-existing characteristics associated with prolonged recovery from concussion in a sample of patients referred to a pediatric sports medicine clinic. STUDY DESIGN This was a retrospective, exploratory cohort study of 247 patients age 5-18 years with concussion referred to a tertiary pediatric hospital-affiliated sports medicine clinic from July 1, 2010, through December 31, 2011. A random sample of all eligible patient visits (3740) was chosen for further review and abstraction. Statistical comparisons between subsets of patients were conducted using exact χ(2) tests, logistic regression, quantile regression, and Kaplan-Meier survival curves. RESULTS The median time until returning to school part-time was 12 days (IQR 6-21); until returning to school full-time without accommodations was 35 days (IQR 11-105); until becoming symptom-free was 64 days (IQR 18-119); and until being fully cleared to return to sports was 75 days (IQR 30-153). Furthermore, 73% of all patients were symptomatic for >4 weeks, 73% were prescribed some form of school accommodation, and 61% reported a decline in grades. Characteristics associated with a prolonged recovery included a history of depression or anxiety; an initial complaint of dizziness; abnormal convergence or symptom provocation following oculomotor examination on physical examination; and history of prior concussion. CONCLUSIONS Pediatric and adolescent patients with concussion may experience cognitive and emotional morbidity that can last for several months following injury. Clinicians should consider specific pre-existing characteristics and presenting symptoms that may be associated with a more complicated recovery for concussion patients.

Cognitive Rest and School-Based Recommendations Following Pediatric Concussion The Need for Primary Care Support Tools

Objectives. (1) Assess pediatric primary care providers’ understanding of cognitive rest for concussion and (2) describe their concussion management practices. Methods. This study included (1) a survey of general pediatric providers and (2) an electronic medical record (EMR) review of children 5 to 18 years old treated for concussion from September 1, 2010, to May 31, 2011. The survey asked about treatment recommendations for concussion, and results were coded to identify cognitive rest recommendations. The EMR review included the following: injury details, medical evaluation, and recommendations for resuming school and sports/recreation. Results. In all, 89 of 201 providers responded to the survey, and 52 of the 84 clinicians who included comments about concussion management mentioned cognitive rest (62%, 95% confidence interval [CI] = 51%-72%). Of the 91 EMRs reviewed for patients’ first visits following the concussion, only 10 (11%, 95% CI = 6%-19%) included written cognitive rest recommendations. Conclusions. Although the majority of pediatric providers identified cognitive rest as important in pediatric concussion management, few provided written recommendations in the EMR.

Vestibular Deficits following Youth Concussion.

OBJECTIVE To characterize the prevalence and recovery of pediatric patients with concussion who manifest clinical vestibular deficits and to describe the correlation of these deficits with neurocognitive function, based on computerized neurocognitive testing, in a sample of pediatric patients with concussion. METHODS This was a retrospective cohort study of patients ages 5-18 years with concussion referred to a tertiary pediatric hospital-affiliated sports medicine clinic from July 1, 2010 to December 31, 2011. A random sample of all eligible patient visits was obtained, and all related visits for those patients were reviewed. RESULTS A total of 247 patients were chosen from 3740 eligible visits for detailed review and abstraction; 81% showed a vestibular abnormality on initial clinical examination. Those patients with vestibular signs on the initial examination took a significantly longer time to return to school (median 59 days vs 6 days, P=.001) or to be fully cleared (median 106 days vs 29 days, P=.001). They additionally scored more poorly on initial computerized neurocognitive testing, and it took longer for them to recover from neurocognitive deficits. Those patients with 3 or more previous concussions had a greater prevalence of vestibular deficits, and it took longer for those deficits to resolve. CONCLUSION Vestibular deficits in children and adolescents with a history of concussion are highly prevalent. These deficits appear to be associated with extended recovery times and poorer performance on neurocognitive testing. Further studies evaluating the effectiveness of vestibular therapy on improving such deficits are warranted.

Rehabilitation Strategies for Prolonged Recovery in Pediatric and Adolescent Concussion

Most pediatric and adolescent concussion patients will heal within 1 month. However, 10% to 20% of adolescent concussions will take longer than 1 month to heal. In this subgroup, prolonged symptoms might include vestibular system deficits, residual neck muscle whiplash injury, exercise intolerance/dysautonomia, and memory issues. At this stage in recovery, these problems respond better to “active rehabilitation” via specific targeted strat egies rather than to strict rest. During follow-up office visits, a careful history and physical exam can elicit specific deficits

Oculomotor and neurocognitive assessment of youth ice hockey players: baseline associations and observations after concussion

Baseline scores on the King-Devick (K-D) Test, Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT), Sport Concussion Assessment Tool 3 (SCAT3), and convergence were evaluated in youth hockey players. Worse K-D times were associated with worse ImPACT visual motor speed and reaction time. Eleven concussed athletes were retested, and there was a trend toward improved ImPACT and K-D times compared to baseline.

Common Lower Extremity Injuries in the Skeletally Immature Athlete

Lower extremity musculoskeletal pain is a common complaint in the adolescent athlete. During rapid growth, several common biomechanical changes occur that may predispose to overuse injury. Unlike fractures, most of these office-based sports medicine complaints are initially evaluated by the primary care provider. This review discusses several of the most common complaints and briefly discusses some clinically significant conditions that masquerade as common injuries. The article discusses only the injuries unique to the growing athlete. The articles goal is to help develop a framework for the pediatric clinician to evaluate common complaints and formulate a plan that includes simple stretches and physical therapy recommendations.
