Glendon K, Blenkinsop G, Belli A, Pain M. A controlled early-exercise rehabilitation program commencing within 48 hours of a Sports-Related Concussion improves recovery in UK student-athletes: A prospective cohort study. J Sci Med Sport 2024:S1440-2440(24)00183-X. [PMID: 38890020 DOI: 10.1016/j.jsams.2024.05.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/07/2024] [Revised: 05/15/2024] [Accepted: 05/19/2024] [Indexed: 06/20/2024]
Abstract
OBJECTIVES Explore if implementing an individualised Sub-Symptom Heart Rate Threshold (SSHeRT) rehabilitation program within 48 hours versus physical rest for 14 days affects recovery following SRC in university-aged student-athletes. DESIGN Prospective, observational cohort study. METHODS Two UK university-aged student-athlete rugby union cohorts were compared (Physical Rest Group (PRG), n = 140, July 2019-March 2020 and Controlled Early-Exercise Group (CEG), n = 167, July 2021-April 2023). Both groups completed the test battery (Post-Concussion Symptom Scale (PCSS), Immediate Post-Concussion and Cognitive Test (ImPACT), Vestibular-Ocular Motor Screening Tool (VOMS)) during pre-season to provide a baseline and within 48 hours, at 4, 8, 14-days post-SRC and at Return to Play (RTP). The PRG (n = 42) physically rested for 14 days as per the nationwide community guidelines. The CEG (n = 52) followed the SSHeRT rehabilitation program. Individual change to baseline was used in all analyses. RESULTS The CEG performed better on ImPACT's verbal memory at 4 (PRG; -5.5 (-10.8-0.0), CEG; 1.0 (-2.0-10.5), p = 0.05) and 14 days (PRG; -2.0 (-10.0-3.0), CEG; 4.0 (-1.0-11.0), p = 0.05) and on the VOMS at 4 (PRG; 3.0 (0.0-12.0), CEG; 0.0 (0.0-5.0), p = 0.03, OR; 2.910) and 14-days post-SRC (PRG; 0.0 (0.0-1.0), CEG; 0.0 (0.0-0.0), OR; 5.914). Near point convergence was better at all time points for the CEG. The CEG was 26.7 % more likely to have RTP within 30 days, and 6.7 and 5.1 times more likely to have resumed non-contact and contact academic activities by 4 days. CONCLUSIONS SSHeRT is safe, can be used within 48 hours of a SRC and may hasten university-aged student-athletes recovery following an SRC.

Abstract
The incidence and prevalence of concussion, a type of mild traumatic brain injury (mTBI), have steadily increased among athletes, both students and professionals, across a wide variety of sports, including, but not limited to, swimming, tennis, football, and boxing. Recent data have demonstrated that sports are one of the leading causes of concussions among student athletes. While the exact mechanism of concussion onset has yet to be fully elucidated, data suggest that the pathophysiology involves rotational acceleration and deceleration of the brain, leading to axon tearing and disturbance in the metabolic cascade of glucose. Concussive events can have debilitating effects on an athlete, including chronic traumatic encephalopathy (gradual degeneration of brain tissue) that is related to personality changes, emotional disorders, and even dementia. Common symptoms associated with concussion include dizziness, nausea, vomiting, and headaches. The physical assessment consists of a combination of tools involving the mental status examination, vital signs, cervical spine exam, eye exam, and neurological testing. The use of osteopathic manipulative medicine (OMM), pharmacotherapy, hyperbaric oxygen therapy (HBOT), aerobic exercise, balance, and/or vestibular therapy are many common treatment approaches for concussion and post-concussion sequelae. This literature review aims to provide insight into concussions, the current treatment options available, and the new developments in concussions per the Amsterdam 2022 International Consensus Statement on Concussion in Sport published in 2023.

Abstract
OBJECTIVE To investigate whether routine daily activities (RDA), non-prescribed exercise (Non-ERx), or prescribed exercise (ERx) were associated with recovery from sport-related concussion (SRC) in collegiate athletes. MATERIALS AND METHODS Data for this cross-sectional, retrospective chart review of collegiate athletes diagnosed with SRC (n = 285[39.6% female], age = 19.5 ± 1.4 years) were collected during the 2015-16 to 2019-20 athletic seasons. The independent variable was group (RDA, Non-ERx, ERx). Dependent variables included days from date of diagnosis to symptom resolution (Dx-SR) and SR to return to sport (SR-RTS). RESULTS Those in the Non-ERx group took nearly 1.3 times longer to achieve SR (IRR = 1.28, 95% CI: 1.11, 1.46) and, 1.8 times longer for RTS (IRR = 1.82, 95% CI: 1.11, 2.71) when compared to those in the RDA group. No other comparisons were significant. CONCLUSION Collegiate athletes in the Non-ERx group took approximately 1 week longer to achieve SR as compared to the RDA and ERx groups. Our findings suggest that if exercise is recommended following SRC, it must be clearly and specifically prescribed. If exercise parameters cannot be prescribed, or monitored, RDA appear to be similarly beneficial during recovery for collegiate athletes with concussion.

Abstract
BACKGROUND While concussions are common pediatric injuries, a lack of agreement on a standard definition of recovery creates multiple challenges for clinicians and researchers alike. HYPOTHESIS The percentage of concussed youth deemed recovered as part of a prospective cohort study will differ depending on the recovery definition. STUDY DESIGN Descriptive epidemiologic study of a prospectively enrolled observational cohort. LEVEL OF EVIDENCE Level 3. METHODS Participants aged 11 to 18 years were enrolled from the concussion program of a tertiary care academic center. Data were collected from initial and follow-up clinical visits ≤12 weeks from injury. A total of 10 recovery definitions were assessed: (1) cleared to full return to sports; (2) return to full school; (3) self-reported return to normal; (4) self-reported full return to school; (5) self-reported full return to exercise; (6) symptom return to preinjury state; (7) complete symptom resolution; (8) symptoms below standardized threshold; (9) no abnormal visio-vestibular examination (VVE) elements; and (10) ≤1 abnormal VVE assessments. RESULTS In total, 174 participants were enrolled. By week 4, 63.8% met at least 1 recovery definition versus 78.2% by week 8 versus 88.5% by week 12. For individual measures of recovery at week 4, percent recovered ranged from 5% by self-reported full return to exercise to 45% for ≤1 VVE abnormality (similar trends at 8 and 12 weeks). CONCLUSION There is wide variability in the proportion of youth considered recovered at various points following concussion depending on the definition of recovery, with higher proportions using physiologic examination-based measures and lower proportions using patient-reported measures. CLINICAL RELEVANCE These results further emphasize the need for a multimodal assessment of recovery by clinicians as a single and standardized definition of recovery that captures the broad impact of concussion on a given patient continues to be elusive.

Abstract
BACKGROUND Numerous individual studies suggest that rest may have a negative effect on outcomes following concussion. PURPOSE To perform a systematic meta-analysis of the effects of prescribed rest compared with active interventions after concussion. STUDY DESIGN Meta-analysis; Level of evidence, 4. METHODS A meta-analysis (using the Hedges g) of randomized controlled trials and cohort studies was conducted to evaluate the effects of prescribed rest on symptoms and recovery time after concussion. Subgroup analyses were performed for methodological, study, and sample characteristics. Data sources were obtained from systematic search of key terms using Ovid Medline, Embase, Cochrane Database of Systematic Reviews, APA PsycINFO, Web of Science, SPORTDiscus, and ProQuest dissertations and theses through May 28, 2021. Eligible studies were those that (1) assessed concussion or mild traumatic brain injury; (2) included symptoms or days to recovery for ≥2 time points; (3) included 2 groups with 1 group assigned to rest; and (4) were written in the English language. RESULTS In total, 19 studies involving 4239 participants met criteria. Prescribed rest had a significant negative effect on symptoms (k = 15; g = -0.27; SE = 0.11; 95% CI, -0.48 to -0.05; P = .04) but not on recovery time (k = 8; g = -0.16; SE = 0.21; 95% CI, -0.57 to 0.26; P = .03). Subgroup analyses suggested that studies with shorter duration (<28 days) (g = -0.46; k = 5), studies involving youth (g = -0.33; k = 12), and studies focused on sport-related concussion (g = -0.38; k = 8) reported higher effect sizes. CONCLUSION The findings support a small negative effect for prescribed rest on symptoms after concussion. Younger age and sport-related mechanisms of injury were associated with a greater negative effect size. However, the lack of support for an effect for recovery time and the relatively small overall numbers of eligible studies highlight ongoing concerns regarding the quantity and rigor of clinical trials in concussion.

Consensus statement: An evidence-based review of exercise, rehabilitation, rest, and return to activity protocols for the treatment of concussion and mild traumatic brain injury. PM R 2023; 15:1605-1642. [PMID: 37794736 DOI: 10.1002/pmrj.13070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2023] [Revised: 07/24/2023] [Accepted: 07/28/2023] [Indexed: 10/06/2023]
Abstract
BACKGROUND Early diagnosis and appropriate management of concussion/mild traumatic brain injury (mTBI) is critical for preventing poor outcomes and minimizing health care burden. Current clinical guidelines for concussion management focus mostly on diagnosis and return to cognitive and physical activity but provide limited guidance on the use of specific therapeutic interventions. OBJECTIVE To systematically review the available evidence on therapeutic interventions for concussion/mTBI and develop an evidence-based consensus statement on the use of these interventions in clinical practice. LITERATURE SURVEY A systematic literature search was performed first in 2018 and 2019, and again in 2022, to identify relevant original research on these interventions. A total of 6303 articles were retrieved through the systematic literature search and screened for inclusion. Eighty articles met inclusion criteria and were included in this review and consensus process. METHODOLOGY A multispecialty panel was convened to explore management of concussion/mTBI. Interventions evaluated included rest, exercise, rehabilitation, and return to activity (RTA) protocols. Studies were assessed for relevance and methodologic quality and were voted upon to develop an evidence-based consensus statement on the therapeutic appropriateness of these interventions for concussion/mTBI. A meta-analysis was not performed. SYNTHESIS There was sufficient evidence to recommend exercise as an appropriate therapy for adolescents with acute concussion/mTBI. In other age groups and for other therapeutic modalities, although some studies demonstrated benefits for some of the interventions, mixed results and study limitations prevented the panel from drawing firm conclusions on the efficacy of those interventions. The panel found evidence of detrimental effects from strict rest and high-intensity physical activity. CONCLUSIONS The panel recommended exercise as an appropriate therapy for acute concussion in adolescents. The evidence on other therapeutic interventions for concussion/mTBI remains limited to small randomized controlled trials and observational studies of moderate to low quality. The panel found no strong evidence to support or recommend against the other evaluated interventions but found most interventions to be safe when used judiciously and in consideration of individual patient needs. High-quality randomized studies with sufficient power are needed to evaluate the effects of rest, rehabilitation, and RTA protocols for the management of concussion/mTBI.

Abstract
BACKGROUND Growing evidence indicates early exercise may improve symptoms and reduce clinical recovery time after concussion, but research examining collegiate student-athletes is scarce. OBJECTIVE The aim of this study was to compare symptom recovery time, clinical recovery time, and persisting post-concussion symptom (i.e., symptoms ≥ 28 days) prevalence by the timing of light exercise initiation before the graded return to play (RTP) protocol among concussed participants. METHODS Collegiate student-athletes (n = 1228; age 18.4 ± 0.9 years; 56.5% male, 76.3% division I; 33.7% ≥ 1 prior concussion) across 30 institutions enrolled in the CARE Consortium completed post-concussion assessments and were monitored over time. Symptom recovery (days from injury to symptom resolution) and clinical recovery (days from injury to return to play protocol completion) was determined by the student-athletes' clinicians. Student-athletes were categorized by timing of light exercise initiation. Early (< 2 days post-concussion; n = 161), typical (3-7 days post-concussion; n = 281), and late exercise (≥ 8 days post-concussion; n = 169) groups were compared with the no-exercise group (n = 617; i.e., did not exercise prior to beginning the RTP protocol) for all analyses. Multivariable Cox regression models with hazard ratios (HR) and survival curves and a multivariable binomial regression model with prevalence ratios (PR) compared recovery outcomes between exercise groups while accounting for covariates. RESULTS Compared to the no-exercise group, the early exercise group was 92% more probable to experience symptom recovery (HR 1.92; 95% CI 1.57-2.36), 88% more probable to reach clinical recovery (HR 1.88; 95% CI 1.55-2.28) and took a median of 2.4 and 3.2 days less to recover, respectively. The late exercise group relative to the no-exercise group was 57% less probable to reach symptom recovery (HR 0.43; 95% CI 0.35-0.53), 46% less probable to achieve clinical recovery (HR 0.54; 95% CI 0.45-0.66) and took 5.3 days and 5.7 days more to recover, respectively. The typical exercise group did not differ in hazard for symptom or clinical recovery (p ≥ 0.329) compared with the no-exercise group. The prevalence of persisting post-concussion symptoms in the combined sample was 6.6%. Early exercise had 4% lower prevalence (PR 0.96, 95% CI 0.94-0.99) and typical exercise had 3% lower prevalence (PR 0.97, 95% CI 0.94-0.99) of persisting post-concussion symptoms, while the late exercise group had an elevated prevalence (PR 1.11, 95% CI 1.04-1.18) compared with the no-exercise group. CONCLUSION Exercise < 2 days post-concussion was associated with more probable and faster symptom and clinical recovery, and lower persisting post-concussion symptom prevalence. When considering our findings and existing literature, qualified clinicians may implement early exercise into their clinical practice to provide therapeutic treatment and improve student-athlete recovery.

Abstract
PURPOSE Young adults with anxiety are vulnerable to developing persistent symptoms following concussions. In order to develop psychosocial interventions to prevent persistent post-concussion symptoms, we need to understand patients' 1) experiences with treatments offered by health care providers; 2) experiences with attempted concussion management strategies; and 3) needs after their injury. METHODS We conducted in-depth interviews with 17 young adults with recent (≤ 10 weeks) concussions who have at least mild anxiety (Generalized Anxiety Disorder Assessment-7 ≥ 5). We used a hybrid deductive-inductive approach to thematic analysis. RESULTS Findings provide insight into recommended treatments (e.g., active/avoidant strategies, accommodations, referrals), attempted strategies (e.g., lifestyle changes, pacing, relationships, acceptance-based coping skills), and patient needs (e.g., education, accommodations, referrals for cognitive and emotional skills). Participants frequently expressed that treatment recommendations were confusing and difficult to implement. They initiated non-prescribed strategies that helped promote recovery and expressed a desire for more interdisciplinary treatment and education on concussions. CONCLUSION Patients' perceptions of health care provider recommendations after concussions did not fully meet patients' perceived needs. Young adults with concussions and anxiety would benefit from more education, guidance, and psychosocial and rehabilitation services. Addressing these gaps may help align treatments with patients' needs and therefore help optimize their recovery.

OBJECTIVE The aims of this study were to determine the incentivization strategy that maximizes patient adherence to report symptoms and activity via ecological momentary assessment (EMA) after pediatric concussion, and assess the feasibility of tracking concussed youth using EMA from the emergency department (ED) setting. METHODS This study was a randomized controlled trial of participants ages 13 to 18 years with concussion presenting to an urban, academic pediatric ED within 5 days of injury. Participants were randomized to 1 of 4 incentive arms: 2 dynamic (loss-based and streak) and 2 control flat-rate (monetary and electronic device). Participants reported symptoms 3 times per day and cognitive activity once each evening for 3 weeks. Physical activity (step count) and sleep were monitored using a Fitbit (kept by participants in the device flat-rate arm). The primary outcome was proportion of prompts to which participants responded. Secondary outcomes included differential response rates by demographics, and comparison of outcome determination between EMA and subsequent clinical visits. RESULTS Thirty participants were enrolled, with a median age of 15.5 years and 60% female. Median cumulative proportion of prompts responded to was 68.3% (interquartile range, 47.6%-82.5%) in the dynamic arms versus 54.0% (interquartile range. 20.6%-68.3%) in the flat-rate arms, P = 0.065. There were nonsignificant differences in median response by sex (65.9% for female vs 40.0% for male, P = 0.072), race/ethnicity (61.9% for non-Hispanic White vs 43.7% for non-Hispanic Black participants, P = 0.097), and insurance (61.9% for private insurance vs 47.6% for public insurance, P = 0.305). Recovery at 3 weeks was discernible for all but 2 participants (93.3%) using EMA data, compared with only 9 participants (30.0%) ( P < 0.001) from clinical visits. CONCLUSIONS Dynamic incentivization showed higher rates of response to tridaily symptom prompts compared with flat-rate incentivization. These data show tracking concussed youth using EMA from the ED is feasible using a dynamic incentivization strategy, with improved ability to discern outcomes compared with prospective monitoring using follow-up clinical visits.

Targeted multidomain intervention for complex mTBI: protocol for a multisite randomized controlled trial in military-age civilians. Front Neurol 2023; 14:1085662. [PMID: 37456641 PMCID: PMC10349652 DOI: 10.3389/fneur.2023.1085662] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Accepted: 06/14/2023] [Indexed: 07/18/2023] Open
Abstract
Background Mild traumatic brain injury (mTBI) affects ~18,000 military personnel each year, and although most will recover in 3-4 weeks, many experience persisting symptoms and impairment lasting months or longer. Current standard of care for U.S. military personnel with complex mTBI involves initial (<48 h) prescribed rest, followed by behavioral (e.g., physical activity, sleep regulation, stress reduction, hydration, nutrition), and symptom-guided management. There is growing agreement that mTBI involves different clinical profiles or subtypes that require a comprehensive multidomain evaluation and adjudication process, as well as a targeted approach to treatment. However, there is a lack of research examining the effectiveness of this approach to assessing and treating mTBI. This multisite randomized controlled trial (RCT) will determine the effectiveness of a targeted multidomain (T-MD) intervention (anxiety/mood, cognitive, migraine, ocular, vestibular; and sleep, autonomic) compared to usual care (behavioral management) in military-aged civilians with complex mTBI. Methods This study employs a single-blinded, two-group repeated measures design. The RCT will enroll up to 250 military-aged civilians (18-49 yrs) with a diagnosed complex mTBI within 8 days to 6 months of injury from two concussion specialty clinics. The two study arms are a T-MD intervention and a usual care, behavioral management control group. All participants will complete a comprehensive, multidomain clinical evaluation at their first clinical visit. Information gathered from this evaluation will be used to adjudicate mTBI clinical profiles. Participants will then be randomized to either the 4-week T-MD or control arm. The T-MD group will receive targeted interventions that correspond to the patient's clinical profile (s) and the control group will receive behavioral management strategies. Primary outcomes for this study are changes from enrollment to post-intervention on the Neurobehavioral Symptom Inventory (NSI), Patient Global Impression of Change (PGIC), and functional near-infrared spectroscopy (fNIRS). Time to return to activity (RTA), and healthcare utilization costs will also be assessed. Discussion Study findings may inform a more effective approach to treat complex mTBI in military personnel and civilians, reduce morbidity, and accelerate safe return-to-duty/activity. Ethics and dissemination The study is approved by the University of Pittsburgh Institutional Review board and registered at clinicaltrials.gov. Dissemination plans include peer-reviewed publications and presentations at professional meetings. Clinical Trial Registration www.clinicaltrials.gov, identifier: NCT04549532.

Abstract
Sport-related concussions (SRCs) are multi-faceted injuries requiring coordinated care for return-to-play (RTP). Although the number of concussions in collegiate football is increasing annually, there is poor standardization among RTP protocols. Recent evidence suggests there is an increased risk of lower extremity injury, neuropsychiatric consequences, and re-injury after SRC, and risk factors for a prolonged recovery from SRC have also been identified. Evidence demonstrates a faster RTP and improved outcomes with early physical therapy intervention; however, this is not yet common practice in the treatment of acute SRC. There is little guidance available on the development and implementation of a multidisciplinary RTP rehabilitation protocol for SRC that incorporates standardized physical therapy. By describing an evidence-based RTP protocol with standardized physical therapy management, and measures taken to implement this protocol, this clinical commentary aims to identify steps in treating SRC that can be used to improve recovery. The purpose of this commentary is to: a) survey the current state of standardization of RTP protocols in collegiate football; b) highlight the development and implementation of a RTP protocol with standardized physical therapy referral and management in an NCAA Division II collegiate football program; and c) describe results of a full-season pilot study, including time to evaluation, time to RTP, rate of re-injury or lower extremity injury, and the clinical significance of protocol implementation.

Abstract
OBJECTIVES Pediatric concussion patients are frequently managed in the primary care or acute care settings. Optimal care includes vision and vestibular assessments, as well as targeted anticipatory guidance for return to school and activity. We aimed to examine clinical practices related to the evaluation and management of concussion patients at children's hospital-based emergency department (ED) and primary care/urgent care settings. METHODS We conducted a retrospective chart review of children aged 5 to 18 years who presented to either the ED or the primary and urgent care settings during a 2-year period. We evaluated 2 concussion management practices: (1) completion of the visio-vestibular examination and (2) provision of anticipatory guidance and follow-up. RESULTS Among patients seen in the ED (n = 500), only 12.4% had at least 1 component of the visio-vestibular examination performed compared with 51.3% of patients (n = 78) in the primary and urgent care settings ( P < 0.05). Regarding anticipatory guidance, 86.2% of ED patients were advised to engage in cognitive rest, and 94.2% were told to physically rest compared with 67.9% and 72.8% in the primary and urgent care settings ( P < 0.05), respectively. Follow-up recommendations were provided similarly for both settings (92.0% in the ED and 85.9% in the primary/urgent care, P = 0.077). CONCLUSIONS Although most pediatric concussion patients receive instructions acutely about cognitive and physical rest, there is opportunity to increase the frequency of visio-vestibular testing in both the ED and the primary care settings. Future efforts should focus on strategies to consistently optimize visio-vestibular assessment given its value in concussion diagnosis.

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 The objective of this study was to document the prevalence of post-computerized neurocognitive test (post-CNT) increases in symptoms in athletes with sport-related concussion, and to examine the effect of post-CNT symptom increases on concussion neurocognitive and vestibular/ocular motor clinical outcomes. METHODS This was a retrospective analysis of medical records from a concussion specialty clinic. Two hundred and three athletes (M = 16.48 ± 1.97 years; 44% [90/203] female) completed a clinical visit for concussion within 30 days of injury (M = 7.73 ± 5.54 days). Computerized neurocognitive testing (the Immediate Post-concussion Assessment and Cognitive Testing: ImPACT), the Post-Concussion Symptom Scale (PCSS), and the Vestibular Ocular Motor Screening (VOMS) were the main outcome measures for the current study. RESULTS Sixty-nine percent (141/203) of the sample did not report significant increases in PCSS scores following post-concussion CNT and were classified into a No Provocation (NO PROV) group. Thirty-one percent (62/203) of participants did report a significant increase in symptoms following post-concussion CNT and were classified into a Provocation (PROV) group. Neurocognitive performance was similar between groups. However, the PROV group reported significantly higher scores on the VOMS symptom items than the NO PROV group. CONCLUSIONS The majority of adolescent athletes can complete a post-concussion CNT without experiencing significant increases in concussion symptoms. Individuals that report symptom increases from completing a post-concussion CNT are more likely to exhibit increased vestibular/ocular motor symptoms. These findings underscore the relationship between the clinical findings from both CNT and vestibular/ocular motor measures following concussion.

Abstract
BACKGROUND Nearly 2 million youth seek acute medical care following concussion in the U.S. each year. Current standard of care recommends rest for the first 48 h after a concussion. However, research suggests that prolonged rest may lengthen recovery time especially for patients with certain risk profiles. Research indicates that physical activity and behavioral management interventions (sleep, stress management) may enhance recovery. To date, there is limited empirical evidence to inform acute (<72 h) concussion recommendations for physical activity and behavioral management in adolescents. OBJECTIVE To determine the effectiveness of physical activity and behavioral management for acute concussion in adolescents and young adults, and to evaluate the role of patient characteristics on treatment response. METHODS This multicenter prospective randomized controlled trial will determine which combination of physical activity and behavioral management is most effective for patients 11-24 years old who present to the emergency department or concussion clinic within 72 h of injury. Participants are randomized into: 1) rest, 2) physical activity, 3) mobile health application (mHealth) behavioral management, or 4) physical activity and mHealth app conditions. Assessments at enrollment, 3-5 days, 14 days, 1 month, and 2 months include: concussion symptoms, balance, vestibular-ocular and cognitive assessments, quality of life, and recovery time. Somatic symptoms and other risk factors are evaluated at enrollment. Compliance with treatment and symptoms are assessed daily using actigraph and daily self-report. The primary study outcome is symptoms at 14 days. CONCLUSION Prescribed physical activity and behavioral management may improve outcomes in youth following acute concussion.

Abstract
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.

Abstract
OBJECTIVES Examine the acute effects (pre-, during, post-intervention) of two different intensities of aerobic exercise or rest on autonomic, oculomotor, and vestibular function and symptom burden in patients with a recent sport-related concussion (SRC) and compare their responses to sex-matched, age-stratified, non-concussed (HEALTHY) student-athletes. METHODS Student-athletes between the ages of 13 and 18 that presented to the sports medicine clinic within Day 3-7 post-SRC and from local schools were recruited for a randomized controlled trial (RCT). The participants were administered the Vestibular/Ocular Motor Screening (VOMS), King-Devick (K-D), and Post-Concussion Symptom Scale (PCSS) before and after the intervention. Heart rate variability (HRV) and mean arterial pressure (MAP) were collected before, during, and after the intervention. The intervention was either a single, 20-min session of treadmill walking at 40% (40HR) or 60% of age-predicted max heart rate (60HR), or seated, rest (NOEX). RESULTS 30 participants completed the intervention with the SRC group treated 4.5 ± 1.3 days post-injury. Pre-exercise HRV and MAP were significantly different (p's < 0.001) during treatment but returned to pre-exercise values within 5 min of recovery in both the SRC and HEALTHY groups. Both the SRC and HEALTHY groups exhibited similar reductions pre- to post-intervention for symptom severity and count (p's < 0.05), three VOMS items (p's < 0.05) but not K-D time. CONCLUSIONS To date, this is the first adolescent RCT to report the acute, systemic effects of aerobic exercise on recently concussed adolescent athletes. The interventions appeared safe in SRC participants, were well-tolerated, and provided brief therapeutic benefit. TRIAL REGISTRATION Clinicaltrials.gov Identifier NCT03575455.

METHODS This was a randomized trial comparing collaborative care to usual care for 200 youth 11-18 years of age with PPCS. In this report, the main outcomes were academic functioning, GPA, school absences, date of return to school, and school days missed. RESULTS Youth were mean age of 14.7 (SD = 1.7), 62.0% female. New or worsening academic problems occurred in half of participants in both groups at 12 months after injury. Students were most concerned about grades and falling behind. There were no significant differences by study group on school problems or GPA, but number of days missed was lower in the collaborative care group compared at 3 months (12.5 [SD = 14.5] vs 16.1 days [20.4] adjusted relative risk [aRR] 0.67 [95% CI: 0.61, 0.74; p < .001]), 6 months (14.5 [22.1] vs 19.3 [26.6] aRR 0.77 [95% CI: 0.71, 0.84; p < .001]), and 12 months (16.9 [25.4] vs 19.6 [27.7], aRR 0.68 [95% CI: 0.62, 0.74; p < .001]). CONCLUSIONS Youth with PPCS are at high risk of school problems in the year after injury.

Abstract
Traumatic brain injury (TBI), also known as a silent epidemic, is currently a substantial public health problem worldwide. Given the increased energy demands following brain injury, relevant guidelines tend to recommend absolute physical and cognitive rest for patients post-TBI. Nevertheless, recent evidence suggests that strict rest does not provide additional benefits to patients' recovery. By contrast, as a cost-effective non-pharmacological therapy, exercise has shown promise for enhancing functional outcomes after injury. This article summarizes the most recent evidence supporting the beneficial effects of exercise on TBI outcomes, focusing on the efficacy of exercise for cognitive recovery after injury and its potential mechanisms. Available evidence demonstrates the potential of exercise in improving cognitive impairment, mood disorders, and post-concussion syndrome following TBI. However, the clinical application for exercise rehabilitation in TBI remains challenging, particularly due to the inadequacy of the existing clinical evaluation system. Also, a better understanding of the underlying mechanisms whereby exercise promotes its most beneficial effects post-TBI will aid in the development of new clinical strategies to best benefit of these patients.

Abstract
IMPORTANCE There are limited data to guide screen time recommendations after concussion. OBJECTIVE To determine whether screen time in the first 48 hours after concussion has an effect on the duration of concussive symptoms. DESIGN, SETTING, AND PARTICIPANTS This randomized clinical trial was conducted in the pediatric and adult emergency departments of a tertiary medical center between June 2018 and February 2020. Participants included a convenience sample of patients aged 12 to 25 years presenting to the emergency department within 24 hours of sustaining a concussion. A total of 162 patients were approached, 22 patients met exclusion criteria, and 15 patients declined participation; 125 participants were enrolled and randomized. INTERVENTIONS Patients were either permitted to engage in screen time (screen time permitted group) or asked to abstain from screen time (screen time abstinent group) for 48 hours after injury. MAIN OUTCOMES AND MEASURES The primary outcome was days to resolution of symptoms, defined as a total Post-Concussive Symptom Scale (PCSS) score of 3 points or lower. Patients completed the PCSS, a 22-symptom scale that grades each symptom from 0 (not present) to 6 (severe), each day for 10 days. Kaplan-Meier curves and Cox regression modeling were used to compare the 2 groups. A Wilcoxon rank sum test was also performed among participants who completed the PCSS each day through recovery or conclusion of the study period. RESULTS Among 125 patients with concussion, the mean (SD) age was 17.0 (3.4) years; 64 participants (51.2%) were male. A total of 66 patients were randomized to the screen time permitted group, and 59 patients were randomized to the screen time abstinent group. The Cox regression model including the intervention group and the patient's self-identified sex demonstrated a significant effect of screen time (hazard ratio [HR], 0.51; 95% CI, 0.29-0.90), indicating that participants who engaged in screen time were less likely to recover during the study period. In total, 91 patients were included in the Wilcoxon rank sum test (47 patients from the screen time permitted group, and 44 patients from the screen time abstinent group). The screen time permitted group had a significantly longer median recovery time of 8.0 days (interquartile range [IQR], 3.0 to >10.0 days) compared with 3.5 days (IQR, 2.0 to >10.0 days; P = .03) in the screen time abstinent group. The screen time permitted group reported a median screen time of 630 minutes (IQR, 415-995 minutes) during the intervention period compared with 130 minutes (IQR, 61-275 minutes) in the screen time abstinent group. CONCLUSIONS AND RELEVANCE The findings of this study indicated that avoiding screen time during acute concussion recovery may shorten the duration of symptoms. A multicenter study would help to further assess the effect of screen time exposure. TRIAL REGISTRATION ClinicalTrials.gov Identifier: NCT03564210.

Abstract
OBJECTIVES: To investigate neurophysiological alterations within the typical symptomatic period after concussion (1-month) and throughout recovery (6-months) in adolescents; and (2) to examine relationships between neurophysiological and upper limb kinematic outcomes.METHODS: 18 adolescents with concussion were compared to 17 healthy controls. Transcranial magnetic stimulation (TMS) was used to assess neurophysiological differences between groups including: short- and long-interval intracortical inhibition, intracortical facilitation, short- and long-latency afferent inhibition, afferent facilitation, and transcallosal inhibition (TCI). Behavioral measures of upper limb kinematics were assessed with a robotic device.RESULTS: Mixed model analysis of neurophysiological data identified two key findings. First, participants with concussion demonstrated delayed onset of interhemispheric inhibition, as indexed by TCI, compared to healthy controls. Second, our exploratory analysis indicated that the magnitude of TCI onset delay in adolescents with concussion was related to upper limb kinematics.CONCLUSIONS: Our findings indicate that concussion in adolescence alters interhemispheric communication. We note relationships between neurophysiological and kinematic data, suggesting an affinity for individuals with less concussion-related physiological change to improve their motor behavior over time. These data serve as an important step in future development of assessments (neurobiological and clinical) and interventions for concussion.

Abstract
ABSTRACT Concussion, a type of mild traumatic brain injury, is a common injury encountered by providers caring for pediatric patients in the emergency department (ED) setting. Our understanding of the pathophysiologic basis for symptom and recovery trajectories for pediatric concussion continues to rapidly evolve. As this understanding changes, so do recommendations for optimal management of concussed youth. As more and more children present to EDs across the country for concussion, it is imperative that providers caring for children in these settings remain up-to-date with diagnostic recommendations and management techniques. This article will review the definition, epidemiology, pathophysiology, diagnosis, and management of pediatric concussion in the ED setting.

Abstract
CONTEXT Emerging research supports the use of mild to moderate aerobic exercise for treating sport-related concussion (SRC) and persistent postconcussive symptoms (PPCS), yet the current standard of care remains to be strict rest. The purpose of this review is to summarize the existing literature on physical activity and prescribed exercise for SRC and PPCS. EVIDENCE ACQUISITION PubMed and Embase were searched in April of 2019 for studies assessing rest or prescribed exercise for SRC and PPCS. No specific search syntax was used. STUDY DESIGN Clinical review. LEVEL OF EVIDENCE Level 4. RESULTS A majority of studies show that spontaneous physical activity is safe after SRC and that subsymptom threshold aerobic exercise safely speeds up recovery after SRC and reduces symptoms in those with PPCS. Exercise tolerance can safely be assessed using graded exertion test protocols within days of injury, and the degree of early exercise tolerance has diagnostic and prognostic value. CONCLUSION Subsymptom threshold aerobic exercise is safe and effective for the treatment of SRC as well as in athletes with PPCS. Further research is warranted to establish the most effective method and dose of aerobic exercise for the active treatment of SRC and whether early exercise treatment can prevent PPCS in athletes. STRENGTH OF RECOMMENDATION TAXONOMY 2.

Abstract
OBJECTIVE To determine whether graded exercise testing can predict recovery trajectory of concussion in children and adolescents. DESIGN Prospective study. SETTING Children's Hospital, Westmead, Australia. PARTICIPANTS One hundred thirty-nine children aged 12 to 16 years at 5 to 7 days after an acute concussive injury. INTERVENTION Graded exercise testing on a treadmill at the subacute phase to assess symptom provocation and determine clinical recovery indicating readiness to commence a return to activity (RTA) protocol. Exercise time to symptom exacerbation and clinical recovery were measured. MAIN OUTCOME MEASURES Standard concussion assessment and clinical testing (neurocognitive, vestibular/ocular, and balance) were conducted to determine major clinical drivers/indicators. RESULTS Participants (mean age 12.4 ± 2.8 years, 73% male) had a confirmed sport-related concussion. The main clinical drivers identified on exercise testing were headache, balance, and vestibular dysfunction. Participants fell into 1 of 2 groups, exercise-tolerant (54%) and exercise-intolerant (46%). Exercise-tolerant patients showed mild clinical indicators, no symptom exacerbation during 10.3 ± 3.3 minutes of exercise, were safely transitioned to a RTA protocol, and recovered within 10 days. Exercise-intolerant patients had high clinical indicators, significant symptom exacerbation at 4.2 ± 1.6 minutes of exercise, and prolonged recovery of 45.6 days. No adverse effects from exercise were reported in either group. Combined use of provocative exercise and clinical testing was 93% predictive of outcome. CONCLUSIONS Exercise testing during the subacute phase after a concussion can predict longer recovery. Exercise testing can identify a unique window where patients can be safely transitioned to activity, enabling clinicians to better inform patients and families, allocate resources and streamline care.

Abstract
CONTEXT Return-to-play following sport-related concussion(SRC) requires authorized clearance from a healthcare provider(HCP). Variability in HCPs and facilities where athletes seek care may influence return time. OBJECTIVE Determine the initial examiner, HCPs that authorize clearance, and medical facilities authorizing clearance among high school student-athletes following SRC, and compare authorized clearance time by HCPs and medical facilities. DESIGN Prospective Cohort Study. SETTING High school. PATIENTS OR OTHER PARTICIPANTS Student-athletes(n=16,001) with SRC participating in STATE-XXX High School Athletic Association(XHSAA)-sponsored athletics. MAIN OUTCOME MEASURE(S) Frequencies of initial examiner and authorized clearance for each HCP(Doctor of Osteopathic Medicine(DO), Doctor of Medicine(MD), Nurse Practitioner(NP), Physician Assistant(PA)) and medical facility (Neurologist's Office, Team Physician, Primary Care Physician or Pediatrician's Office(PCP), Hospital, Urgent/Ready Care) for each SRC case. Kaplan-Meier curves and Peto tests evaluated differences in median time to authorized clearance between HCPs and facilities. Only cases with a follow-up authorized clearance date(80.3%, n=12,856) were included in authorized clearance and time to return analyses. RESULTS An athletic trainer was at least one of the initial examiners for 71.3%(n=11,404) of cases; 80.2%(n=12,990) had only one initial examiner. There was an association between initial examiner and medical facility providing clearance for athletic director(χ2=52.6, p≤.001, V=.06), athletic trainer(χ2=172.0, p≤.001, V=.12), coach(χ2=161.5, p≤.001, V=.11), DO(χ2=59.4, p≤.001, V= 07), and NP(χ2=10.0, p .03, V=.12). The majority(n=8,218, 63.9%) received clearance by an MD; 70.8%(n=9,099) were cleared at a PCP. Median time to authorized clearance varied by facility(Urgent/Ready Care: 7 days[4,11], Hospital: 9 days[6,14], PCP: 10 days[6,14], Team Physician: 12 days[8,16], Neurologist Office: 13 days[9,20]; p ≤ .001). CONCLUSIONS Clearance was frequently provided by an MD and at a PCP. Median time to return to unrestricted participation following SRC varied by HCP and medical facility. Future research should elucidate why differences exist and determine why athletes seek care at different medical facilities.

Abstract
OBJECTIVE To evaluate the effect of cognitive and physical rest on persistent postconcussive symptoms in a pediatric population. STUDY DESIGN A prospective cohort study of 5- to 18-year-olds diagnosed with an acute concussion in a tertiary care pediatric emergency department was conducted from December 2016 to May 2019. Participants (n = 119) were followed over 1 month to track days off from school and sports and the development of persistent postconcussive symptoms (residual concussion symptoms beyond 1 month). Participants were dichotomized into minimal (≤2) and moderate (>2) rest, based on days off from school and sports after a concussion. Univariate and multivariable logistic regression analyses were completed to examine associations with persistent postconcussive symptoms. RESULTS Of the participants in our study, 24% had persistent postconcussive symptoms. Adolescent age, history of prolonged concussion recovery, and headache at presentation were associated with higher odds of persistent postconcussive symptoms in univariate analyses. In a multivariable logistic regression model, only adolescent age was associated with increased odds of persistent postconcussive symptoms. Compared with the minimal cognitive rest group, moderate cognitive rest did not decrease the odds of persistent postconcussive symptoms (aOR, 1.15; 95% CI, 0.44-2.99). Compared with the minimal physical rest group, moderate physical rest also did not decrease the odds of persistent postconcussive symptoms (aOR, 3.17; 95% CI, 0.35-28.78). CONCLUSIONS Emerging evidence supports early return to light activity for recovery of acute pediatric concussion. Our study adds to this management approach as we did not find that rest from school and sports resulted in a decreased odds of persistent postconcussive symptoms.

Abstract
OBJECTIVE The primary objective is to evaluate the feasibility (safety and acceptability) of implementing early active rehabilitation (AR) for concussion management in youth with symptoms persisting 2 weeks after injury. A secondary and exploratory objective was to estimate the potential efficacy of early AR compared with standard AR. We hypothesize that AR at 2-weeks postconcussion will be safe and acceptable to patients. DESIGN Randomized clinical trial. SETTING The Montreal Children's Hospital of the McGill University Health Center (MCH-MUHC), a tertiary care pediatric teaching hospital affiliated with McGill University in Montreal, Canada. PARTICIPANTS Twenty youth aged 9 to 17 years old with postconcussion symptoms for at least 2 weeks. INTERVENTION Active rehabilitation (aerobic exercise, coordination drills, visualization, and education/reassurance) was administered by physiotherapists in-person, and then continued as a home program. METHODS Twenty participants were randomized to either early AR (initiated 2 weeks after injury) or standard AR (initiated 4 weeks after injury). RESULTS Two adverse events (one in each group) were identified through an online survey more than one-month postconcussion. Postconcussion symptoms decreased over time for both groups. CONCLUSIONS The results from this pilot study indicate that a full clinical trial estimating the efficacy of early AR (starting 2 weeks after injury) is feasible. Further study is needed to determine the superiority of this strategy over current treatment approaches.

Mode and Intensity of Physical Activity During the Postacute Phase of Sport-Related Concussion: A Systematic Review. J Sport Rehabil 2020; 30:492-500. [PMID: 32871551 DOI: 10.1123/jsr.2019-0323] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/16/2019] [Revised: 05/29/2020] [Accepted: 06/01/2020] [Indexed: 11/18/2022]
Abstract
INTRODUCTION Sports-related concussions (SRCs) have received attention due to their prevalence in youth. An SRC results from a strong force causing neurological impairment. Recent research has recommended rehabilitation within the first week post-SRC after 24 to 48 hours of rest. The postacute phase is defined as 48 hours to 7 days post-SRC. It is imperative to evaluate the most effective mode and intensity of physical activity to reduce symptoms and improve outcomes. METHODS CINAHL, PubMed, SPORTDiscus, and Web of Science databases were used to search the terms "brain concussion" AND "exercise" and variations of these terms. The evidence level for each study was evaluated using the 2011 Oxford Center for Evidence-Based Medicine Guide. The methodological rigor of each study was evaluated using a scale adapted from Medlicott and Harris. RESULTS Two thousand sixty-eight records were identified. Six studies were included in this systematic review. Three studies were classified as moderately strong. The remaining 3 studies were considered weak. Five of the studies used either a cycle ergometer or a treadmill. The sixth study used walking, cycling, and swimming, as well as sports drills. All of these modes of exercise were determined to be safe. All studies utilized low- and moderate-intensity interventions, which were found to be nondetrimental and showed improved recovery time and symptom resolution. Five of the studies also incorporated components of high-intensity exercise that was also found to be nondetrimental, and they showed a positive influence on recovery time and symptom resolution. However, all activity in each of the reviewed studies started at a low level and progressed up to a higher level only as each individual client's symptoms permitted. DISCUSSION Overall, this review found that various modes of activity at light-, moderate-, and high-intensity levels are efficacious and can be safely used during the postacute phase of SRC. CONCLUSION Though the volume of literature at this time is limited, therapists should consider prescribing closely monitored individualized exercise programs utilizing progressive intensities when treating patients during the postacute phase of SRC.

Abstract
Aims: Recent research suggests that aerobic exercise can be performed safely within the first week following a concussion injury and that early initiation of exercise may speed recovery. To better understand the physiological changes during a concussion, we tested the hypothesis that mild-to-intense exercise testing can be performed within days immediately following injury, and can be used to discern differences between the concussed and normal healthy state. Thus, the purpose was to observe the cerebral hemodynamic responses to incremental exercise testing performed acutely post-concussion in high-performance athletes. Methods: This study was a within- and between-experimental design, with seven male university ice hockey teams participating. A subgroup of five players acted as control subjects (CON) and was tested at the same time as the 14 concussed (mTBI) players on Day 2, 4, and 7 post-concussion. A 5-min resting baseline and 5-min exercise bouts of mild (EX1), moderate (EX2), and high (EX3) intensity exercise were performed on a cycle ergometer. Near-infrared spectroscopy was used to monitor pre-frontal cortex oxy-haemoglobin (HbO2), deoxy-haemoglobin (HHb), and total blood volume (tHb) changes. Results: ANOVA compared differences between testing days and groups, and although large percentage changes in HbO2 (20-30%), HHb (30-40%), and tHb (30-40%) were recorded, no significant (p ≤ 0.05) differences in cerebral hemodynamics occurred between mTBI vs. CON during aerobic exercise testing on any day post-injury. Furthermore, there was a linear relationship between exercise intensity vs. cerebral hemodynamics during testing for each day (r 2 = 0.83-0.99). Conclusion: These results demonstrate two novel findings: (1) mild-to-intense aerobic exercise testing can be performed safely as early as Day 2 post-concussion injury in a controlled laboratory environment; and (2) evidence-based objective measures such as cerebral hemodynamics can easily be collected using near-infrared spectroscopy (NIRS) to monitor physiological changes during the first-week post-injury. This research has important implications for monitoring physiological recovery post-injury and establishing new rehabilitation guidelines.

Abstract
We examined the effect of a noncontact, subsymptom exacerbation early exercise recommendation on recovery from sports-related concussion. Retrospective analysis of adolescents, 10-17 years old, with symptomatic concussion, within 30 days of injury was performed. Time to recovery was measured between the early exercise group and a comparison group. A total of 187 patients studied-112 in the exercise group and 75 in the comparison group; 55% were male (n = 103). The exercise group had a significantly longer duration of concussion symptoms (18.5 days vs 14, P = .002), although both groups recovered within the expected time to recovery for concussion. When analyzed separately, males experienced longer time to recovery from injury (19 days vs 14, P = .003), than females, respectively (18 days vs 14.5, P = .18). Recommendation of early exercise resulted in significantly longer recovery from concussion in male adolescents but had no significant effect in female adolescents; both groups recovered within the expected time frame.

Abstract
Return to activity (RTA) and return to school (RTS) are important issues in pediatric concussion management. This study aims to update CanChild's 2015 RTA and RTS protocols, on the basis of empirical data and feedback collected from our recently completed prospective cohort study, focusing on concussed children and their caregivers; systematic review of evidence published since 2015; and consultation with concussion management experts. The new protocols highlight differences from the earlier versions, mainly, (1) symptom strata to allow quicker progression for those who recover most quickly; (2) a shortened rest period (24-48 hours) accompanied by symptom-guided activity; (3) the recommendation that children progress through the stages before they are symptom free, if symptoms have decreased and do not worsen with activity; (4) specific activity suggestions at each stage of the RTA protocol; (5) recommendations for the amount of time to spend per stage; and (6) integration of RTS and RTA.

Abstract
CONTEXT Concussion management is moving from passive rest strategies to active interventions, including aerobic exercise therapy. Little information is available regarding the feasibility and adherence of these programs. OBJECTIVES To determine whether an aerobic exercise training program intended for rehabilitation in people with concussion is feasible. Healthy, nonconcussed subjects were studied in this phase 1 trial. DESIGN Phase 1 parallel-group, randomized controlled trial in a sample of healthy (nonconcussed), recreationally active university students. SETTING Laboratory. PATIENTS 40 healthy university students. METHODS Participants were equally randomized to acute concussion therapy intervention (ACTIVE) training or nontraining groups. All participants completed maximal cardiopulmonary exercise tests on a stationary cycle ergometer at 2 test sessions approximately 14 days apart. During this 2-week study period, ACTIVE training participants completed six 30-minute cycling sessions, progressing from 60% to 80% of the participant's individualized maximal oxygen consumption. A subset of participants (NACTIVE = 12, Nnontraining = 11) wore physical activity monitors throughout the 2-week study period. MAIN OUTCOMES MEASURES Study protocol and randomization effectiveness, exercise safety and adherence, and progressive intensity of the ACTIVE training procedures. RESULTS No adverse events occurred during any exercise sessions. Twelve ACTIVE training participants (60%) completed all training sessions, and every participant completed at least 4 sessions. Heart rate increased throughout the training period (P < .001), but symptom changes and training adherence remained stable despite the progressively increasing workload. ACTIVE training participants completed approximately 30 additional minutes of physical activity on training sessions days, although that was not statistically significant (P = .20). CONCLUSIONS University-aged students were adherent to the ACTIVE training protocol. Future research should investigate the safety and feasibility of aerobic training programs in acutely concussed individuals to determine their appropriateness as a clinical rehabilitation strategy.

Abstract
CONTEXT Interest in identifying the effects of physical and mental activity on recovery after sport-related concussion is growing. Clinical studies of concussed athletes' activities require well-validated methods for tracking their intensity and timing. OBJECTIVE To develop and validate a novel multimodal approach to monitoring activity postconcussion using mobile (mHealth) technologies. DESIGN Cohort study. SETTING Translational research unit. PATIENTS OR OTHER PARTICIPANTS A total of 40 high school and collegiate football players were evaluated at preseason and followed longitudinally after either concussion (n = 25; age = 17.88 ± 1.74 years, height = 182.07 ± 8.08 cm, mass = 98.36 ± 21.70 kg) or selection as a nonconcussed control (n = 15; age = 18.27 ± 1.83 years, height = 180.01 ± 7.19 cm, mass = 93.83 ± 24.56 kg). MAIN OUTCOME MEASURE(S) Participants wore a commercial actigraph and completed a daily mobile survey for 2 weeks. Analyses focused on comparisons between groups for actigraph-based physical activity and self-reported physical and mental activity during the follow-up period. RESULTS For the first 2 days postinjury, objective measures showed fewer daily steps in concussed (6663 ± 2667 steps) than in control (11 148 ± 3381 steps) athletes (P < .001), and both objective and self-reported measures indicated less moderate to vigorous physical activity in concussed (27.6 ± 32.6 min/d and 25.0 ± 43.6 min/d, respectively) than in control (57.3 ± 38.6 min/d and 67.5 ± 40.1 min/d, respectively) athletes (both P values < .05). Correlations between objective and self-reported measures of moderate to vigorous physical activity were moderate across select 1-week and 2-week averages. We observed no group differences in self-reported mental activities. CONCLUSIONS Physical activity after sport-related concussion varied widely across athletes but on average was reduced during the acute and early subacute postinjury periods for both objective and self-reported measures. The lack of differences in mental activities between groups may reflect limited change in mental exertion postconcussion or difficulty accurately measuring mental activities. Assessing concussed athletes' activities using actigraphy and self-reported scales may help monitor their compliance with activity recommendations and be useful in studies aimed at better understanding the effects of physical activity on concussion recovery.

Abstract
INTRODUCTION Concussion diagnosis and rehabilitation management has become a prevalent area of research, and yet much is still unknown about these complex injuries. Historically, exercise prescription post-concussion was conservatively used for rehabilitation due to the suspected harmful effects that exercise can have on damaged neurons, and increase in symptoms. However, there has been a shift to implement exercise earlier into recovery as several studies have demonstrated positive outcomes. OBJECTIVE The objective of this literature review is to update the reader about new advances in concussion research related to the beneficial effects of physical activity from both a neurometabolic and a broader physiological perspective, using gene expression as a vehicle to demonstrate why and how physical activity has the capacity to optimize recovery from a cellular perspective. To further this clinical guideline, the evidence must continue to support these positive outcomes from an inductive and deductive physiologic approach (i.e., the clinical evidence aligned from a micro- to macroscopic approach and vice versa). DESIGN Narrative review. METHODS Pubmed and Medline were used with the following key words: concussion and, physical activity, neurometabolic, gene regulation, trauma, nervous system, mild head injury, acute exercise, cellular physiology and pathophysiology. CONCLUSION It is our contention that understanding the cellular perspective will help guide clinical management, and promote research into post-concussion exercise.

Abstract
Design: Prospective cohort study. Background: The recommendations regarding the optimal amount and type of rest for promoting recovery following concussion are based on expert opinion rather than evidence-based guidelines due to current a lack of high-level studies. There is an evident need for more research into the parameters of rest and activity and its effects on recovery from concussion. Objective: To evaluate the association between the amount of moderate and vigorous physical activity (MVPA) during the first 3 days following concussion diagnosis and time to medical clearance (days) to return to play in youth ice hockey players. Methods: Thirty youth ice hockey players (12–17 years) that were diagnosed with a concussion sustained during ice hockey were recruited to participate. The exposure was the cumulative amount of MVPA (minutes), measured using a waist-worn Actigraph accelerometer. Participants were dichotomized into high (≥148.5) and low (<148.5) activity groups based on the median of cumulative time spent in MVPA over the first 3 days following injury diagnosis. Results: Participants in both the low and high activity group reported to the clinic at a median time of 4 days post-injury (low activity IQR: 3–5 days; high activity IQR: 3–7 days). The low activity group completed a median time of 110.7 min (IQR: 76.2–131.0 min) in MVPA, whereas the high activity had a median of 217.2 min (IQR 184.2–265.2 min) in MVPA. Kaplan Meier survival curves with Log-rank tests of hypothesis revealed the high activity group took significantly more time to be medically cleared to return to play (p = 0.041) compared to the low activity group. Conclusion: The results from this study suggest that more time in MVPA early in the recovery period may result in a greater time to medical clearance to return to full participation in ice hockey. Future research, using valid measures of activity, are required to better understand the relationship between early activity and recovery following concussion in youth.

Abstract
Emerging evidence supports an active approach for acute pediatric concussion management. The current practices of pediatric emergency providers following acute concussions has not been well studied. We prospectively enrolled 134 pediatric patients with an acute concussion. Providers completed a real-time survey to assess their recommendations for time off from school and sports. Seven to 10 days post-injury, patient compliance with provider recommendations was assessed. Forty-seven (35.1%) providers recommended moderate time off from school. In this cohort (n = 44), 14 (31.8%) patients took more than 2 days off from school. When minimal rest was prescribed (n = 80), 26 (32.5%) patients took more than 2 days off from school, P = .94. One third of our pediatric emergency providers are still recommending moderate time off from school. Regardless of physician prescriptions, patients took a similar amount of time off from school. Our study questions the influence of physician recommendations on management of acute pediatric concussions.

Abstract
Considerably less attention has been paid to psychological and social sequelae of
concussion in youth athletes compared with neurocognitive outcomes. This
narrative review consolidates the literature on postconcussive emotional and
psychosocial functioning in school-aged children and adolescents, highlighting
athlete-specific findings. MEDLINE and PsycINFO databases were queried for
pediatric concussion studies examining psychological and/or social outcomes, and
604 studies met search criteria (11 of those specific to sport). Results were
organized into domains: emotional and social dysfunction, behavioral problems,
academic difficulties, sleep disturbance, headache, and quality of life. The
small body of literature regarding psychological and social issues following
pediatric concussion suggests behavioral disturbances at least temporarily
disrupt daily life. Extrapolation from samples of athletes and nonathletes
indicates postconcussive anxiety and depressive symptoms appear, although levels
may be subclinical. Social and academic findings were less clear. Future
well-controlled and adequately powered research will be essential to anticipate
concussed athletes’ psychosocial needs.

Abstract
Clinical Scenario: Currently, rest following concussion serves as the keystone of concussion treatment, but substantial evidence to support it is lacking. Recent literature suggests that early physical activity may be beneficial in reducing concussion symptoms which may influence clinical recovery time. Clinical Question: Does early physical activity decrease postconcussion symptoms compared to physical rest following concussion? Summary of Key Findings: A total of 5 articles were included that examined symptom duration changes at multiple time points. All 5 studies utilized follow-up time points compared to initial examination, but there was variance in the specific time points reported. Two studies employed control groups and compared strict or recommended rest to early activity or limited rest. Three studies were observational studies that directly compared baseline measurements to follow-up assessments. Clinical Bottom Line: Current evidence suggests that early physical activity in the acute phase following a concussion may decrease the time needed for symptom resolution compared to immediate rest. Strength of Recommendation: Using Centre for Evidence-Based Medicine 2011 level 3 evidence and higher, the results suggest that early physical activity during the acute phase of a concussion may decrease symptom duration; however, a lack of high-quality studies and inconsistent interventions are limitations to this recommendation.

Abstract
Sport-related concussion is an important topic in nearly all sports and at all levels of sport for children and adolescents. Concussion knowledge and approaches to management have progressed since the American Academy of Pediatrics published its first clinical report on the subject in 2010. Concussion's definition, signs, and symptoms must be understood to diagnose it and rule out more severe intracranial injury. Pediatric health care providers should have a good understanding of diagnostic evaluation and initial management strategies. Effective management can aid recovery and potentially reduce the risk of long-term symptoms and complications. Because concussion symptoms often interfere with school, social life, family relationships, and athletics, a concussion may affect the emotional well-being of the injured athlete. Because every concussion has its own unique spectrum and severity of symptoms, individualized management is appropriate. The reduction, not necessarily elimination, of physical and cognitive activity is the mainstay of treatment. A full return to activity and/or sport is accomplished by using a stepwise program while evaluating for a return of symptoms. An understanding of prolonged symptoms and complications will help the pediatric health care provider know when to refer to a specialist. Additional research is needed in nearly all aspects of concussion in the young athlete. This report provides education on the current state of sport-related concussion knowledge, diagnosis, and management in children and adolescents.

Abstract
BACKGROUND About 5-15 % of patients with concussion experience persistent post-concussion symptoms (PCS) longer than 3 months post-injury. OBJECTIVE To explore the feasibility of a new intervention for young patients with persistent PCS and long-term changes after intervention. METHODS Thirty-two consecutive patients (15-30 years) with persistent PCS 2-4 months post-injury were recruited from a cohort study or referred to a non-randomized feasibility study of an individually tailored, 8-week, multidisciplinary intervention. Assessment was performed at baseline, end of intervention (EOI), and at 3- and 12-month follow-up (FU). Main measures were The Experience of Service Questionnaire (ESQ), Rivermead Post-Concussion Symptoms Questionnaire (RPQ) and The Quality of Life after Brain Injury - Overall Scale (QOLIBRI-OS). RESULTS Twenty-three (72%) patients completed the intervention. The ESQ demonstrated high patient satisfaction. There was a decrease of PCS and an increase in quality of life from baseline to EOI: RPQ score -8.9 points, 95% CI 4.5 to 13.3, p < 0.001; QOLIBRI-OS score +10.5 points, 95% CI 2.5 to 18.5, p = 0.010. Improvement was maintained at 3- and 12-month FU. CONCLUSION The new early intervention is feasible and may prevent chronification of PCS. An RCT is currently performed to evaluate the effect of the intervention.

Abstract
The management of concussion in pediatric patients has always been guided by treatment guidelines that have been drawn from consensus statements rather than clinical research projects. Grool and colleagues conducted a clinical research project on an early return to physical activity and its effect on post-concussion symptoms. The study enrolled 3063 pediatric patients, age 5.0 to 17.99 years of age who presented to one of nine Pediatric Emergency Research Centers in Canada. 2413 patients completed the primary outcome for exposure. A total of 1677 patients (69.5%) instituted some level of early physical activity, including light aerobic exercise (n = 795 or 32.9%), sport-specific exercise (n = 214 or 8.9%), non-contact drills (n = 143 or 5.9%), full-contact practice (n = 106 or 4.4%), or full competition (n = 419 or 17.4%), while 736 (30.5%) instituted no physical activity. Patients were evaluated by a web-based survey or a telephone-based survey at days 7 and 28 after their initial visit, and their symptoms were evaluated by using the Post Concussive Symptom Inventory (PCSI). Early return to physical activity was associated with a lower risk of Persistent Post-Concussive Syndrome (PPCS) than in patients reporting no physical activity at 28 days (24.6% vs. 43.5%, Absolute risk difference, (ARD), 18.9% (95% CI 14.7-23.0%). Among the sub-group of patients who were symptomatic at day 28 (n = 803), PPCS was more present in the patients that reported no physical activity, (n = 584: PPCS 52.9%), than those with light aerobic activity (n = 494 [46.4%; ARD, 6.5%; 95% CI 5.7-12.5%], moderate activity [n = 176 (38.6%; ARD, 14.3%; 95% CI 5.9%-22.2%], or full contact activity [n = 133 (36.1%; ARD, 16.8%; 95% CI 7.5%- 25.5%]. Therefore, in patients aged 5 to 18 years with acute concussion, a return to physical activity within 7 days of acute injury was associated with less symptoms at 28 days than in patients who had a period of prolonged rest rather than an early return to physical activity.

Abstract
Sport-related concussion (SRC) is a physiological brain injury that produces cerebral and systemic effects, including exercise intolerance. Exercise intolerance after concussion is believed to be the result of autonomic nervous system (ANS) dysfunction. Ventilation is inappropriately low for the level of exercise intensity, raising arterial carbon dioxide (PaCO2) levels. Elevated PaCO2 increases cerebral blood flow (CBF) out of proportion to exercise intensity, which is associated with symptoms that limit exercise performance. Thus, elevated exercise PaCO2 may signal incomplete recovery from SRC. This article reviews recent observational and experimental data and presents the evidence that subthreshold aerobic exercise normalizes the cerebrovascular physiological dysfunction and is "medicine" for patients with concussion and persistent postconcussive symptoms (PPCS). It discusses the systematic evaluation of exercise tolerance after concussion using the Buffalo Concussion Treadmill Test (BCTT) and reviews the utility of the Buffalo Concussion Bike Test (BCBT), the data from which are used to establish an individualized heart rate "dose" of subthreshold exercise to safely speed recovery, which also may work in the acute recovery phase after SRC with the potential to reduce the incidence of PPCS. Evaluation and treatment approaches based on the physiology of concussion suggest that exercise is medicine for concussion, potentially adding a new dimension to concussion care to help safely speed recovery and prevent PPCS in some patients.

Abstract
OBJECTIVE The Concussion in Sport Group guidelines recommend a multifaceted approach to help clinicians make return to sport decisions. The purpose of this study was to identify the most common multifaceted measures used to define clinical recovery from sport-related concussion in young athletes (high school and/or college level) and to summarise existing knowledge of criteria used to make return to sport decisions. DESIGN Systematic review. DATA SOURCES The PubMed (MEDLINE), SPORTDiscus and Embase electronic databases were searched from 1 January 2000 to 1 March 2017 by three independent reviewers. ELIGIBILITY CRITERIA Inclusion criteria: elementary, high school and college age groups, and a specific definition of clinical recovery that required two or more measures. EXCLUSION CRITERIA review articles, articles using the same sample population, case studies, non-English language and those that used one measure only or did not specify the recovery measures used. STUDY QUALITY Study quality was assessed using the Downs and Black Criteria. RESULTS Of 2023 publications, 43 met inclusion criteria. Included articles reported the following measures of recovery: somatic symptom resolution or return to baseline (100%), cognitive recovery or return to baseline (86%), no exacerbation of symptoms on physical exertion (49%), normalisation of balance (30%), normal special physical examination (12%), successful return to school (5%), no exacerbation of symptoms with cognitive exertion (2%) and normalisation of cerebral blood flow (2%). Follow-up to validate the return to sport decision was reported in eight (19%) articles. Most studies were case-control or cohort (level of evidence 4) and had significant risk of bias. CONCLUSION All studies of sport-related concussion use symptom reports to define recovery. A minority of studies used multiple measures of outcome or had clearly defined recovery criteria, the most common being a combination of a self-reported symptom checklist and a computerised neurocognitive test. Future studies ideally should define recovery a priori using objective physiological measures in addition to symptom reports.
