Exploring the challenges of avoiding collisions with virtual pedestrians using a dual-task paradigm in individuals with chronic moderate to severe traumatic brain injury.

BACKGROUND: Individuals with a moderate-to-severe traumatic brain injury (m/sTBI), despite experiencing good locomotor recovery six months post-injury, face challenges in adapting their locomotion to the environment. They also present with altered cognitive functions, which may impact dual-task walking abilities. Whether they present collision avoidance strategies with moving pedestrians that are altered under dual-task conditions, however, remains unclear. This study aimed to compare between individuals with m/sTBI and age-matched control individuals: (1), the locomotor and cognitive costs associated with the concurrent performance of circumventing approaching virtual pedestrians (VRPs) while attending to an auditory-based cognitive task and; (2) gaze behaviour associated with the VRP circumvention task in single and dual-task conditions. METHODOLOGY: Twelve individuals with m/sTBI (age = 43.3 ± 9.5 yrs; >6 mo. post injury) and 12 healthy controls (CTLs) (age = 41.8 ± 8.3 yrs) were assessed while walking in a virtual subway station viewed in a head-mounted display. They performed a collision avoidance task with VRPs, as well as auditory-based cognitive tasks (pitch discrimination and auditory Stroop), both under single and dual-task conditions. Dual-task cost (DTC) for onset distance of trajectory deviation, minimum distance from the VRP, maximum lateral deviation, walking speed, gaze fixations and cognitive task accuracy were contrasted between groups using generalized estimating equations. RESULTS: In contrast to CTLs who showed locomotor DTCs only, individuals with m/sTBI displayed both locomotor and cognitive DTCs. While both groups walked slower under dual-task conditions, only individuals with m/sTBI failed to modify their onset distance of trajectory deviation and maintained smaller minimum distances and smaller maximum lateral deviation compared to single-task walking. Both groups showed shorter gaze fixations on the approaching VRP under dual-task conditions, but this reduction was less pronounced in the individuals with m/sTBI. A reduction in cognitive task accuracy under dual-task conditions was found in the m/sTBI group only. CONCLUSION: Individuals with m/sTBI present altered locomotor and gaze behaviours, as well as altered cognitive performances, when executing a collision avoidance task involving moving pedestrians in dual-task conditions. Potential mechanisms explaining those alterations are discussed. Present findings highlight the compromised complex walking abilities in individuals with m/sTBI who otherwise present a good locomotor recovery.

Social determinants of health and disparities in pediatric trauma care: protocol for a systematic review and meta-analysis.

BACKGROUND: Social determinants of health (SDH), including "the conditions in which individuals are born, grow, work, live and age" affect child health and well-being. Several studies have synthesized evidence about the influence of SDH on childhood injury risks and outcomes. However, there is no systematic evidence about the impact of SDH on accessing care and quality of care once a child has suffered an injury. We aim to evaluate the extent to which access to care and quality of care after injury are affected by children and adolescents' SDH. METHODS: Using Cochrane methodology, we will conduct a systematic review including observational and experimental studies evaluating the association between social/material elements contributing to health disparities, using the PROGRESS-Plus framework: place of residence, race/ethnicity/culture/language, occupation, gender/sex, religion, education, socioeconomic status, and social capital and care received by children and adolescents (≤ 19 years of age) after injury. We will consult published literature using PubMed, EMBASE, CINAHL, PsycINFO, Web of Science, and Academic Search Premier and grey literature using Google Scholar from their inception to a maximum of 6 months prior to submission for publication. Two reviewers will independently perform study selection, data extraction, and risk of bias assessment for included studies. The risk of bias will be assessed using the ROBINS-E and ROB-2 tools respectively for observational and experimental study designs. We will analyze data to perform narrative syntheses, and if enough studies are identified, we will conduct a meta-analysis using random effects models. DISCUSSION: This systematic review will provide a synthesis of evidence on the association between SDH and pediatric trauma care (access to care and quality of care) that clinicians and policymakers can use to better tailor care systems and promote equitable access and quality of care for all children. We will share our findings through clinical rounds, conferences, and publication in a peer-reviewed journal. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42023408467.

Clinical Practice Guideline Recommendations in Pediatric Mild Traumatic Brain Injury: A Systematic Review.

STUDY OBJECTIVE: Our primary objectives were to identify clinical practice guideline recommendations for children with acute mild traumatic brain injury (mTBI) presenting to an emergency department (ED), appraise their overall quality, and synthesize the quality of evidence and the strength of included recommendations. METHODS: We searched MEDLINE, EMBASE, Cochrane Central, Web of Science, and medical association websites from January 2012 to May 2023 for clinical practice guidelines with at least 1 recommendation targeting pediatric mTBI populations presenting to the ED within 48 hours of injury for any diagnostic or therapeutic intervention in the acute phase of care (ED and inhospital). Pairs of reviewers independently assessed overall clinical practice guideline quality using the Appraisal of Guidelines Research and Evaluation (AGREE) II tool. The quality of evidence on recommendations was synthesized using a matrix based on the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) Evidence-to-Decision framework. RESULTS: We included 11 clinical practice guidelines, of which 6 (55%) were rated high quality. These included 101 recommendations, of which 34 (34%) were based on moderate- to high-quality evidence, covering initial assessment, initial diagnostic imaging, monitoring/observation, therapeutic interventions, discharge advice, follow-up, and patient and family support. We did not identify any evidence-based recommendations in high-quality clinical practice guidelines for repeat imaging, neurosurgical consultation, or hospital admission. Lack of strategies and tools to aid implementation and editorial independence were the most common methodological weaknesses. CONCLUSIONS: We identified 34 recommendations based on moderate- to high-quality evidence that may be considered for implementation in clinical settings. Our review highlights important areas for future research. This review also underlines the importance of providing strategies to facilitate the implementation of clinical practice guideline recommendations for pediatric mTBI.

Pediatric vs Adult or Mixed Trauma Centers in Children Admitted to Hospitals Following Trauma: A Systematic Review and Meta-Analysis.

Importance: Adult trauma centers (ATCs) have been shown to decrease injury mortality and morbidity in major trauma, but a synthesis of evidence for pediatric trauma centers (PTCs) is lacking. Objective: To assess the effectiveness of PTCs compared with ATCs, combined trauma centers (CTCs), or nondesignated hospitals in reducing mortality and morbidity among children admitted to hospitals following trauma. Data Sources: MEDLINE, Embase, and Web of Science through March 2023. Study Selection: Studies comparing PTCs with ATCs, CTCs, or nondesignated hospitals for pediatric trauma populations (aged ≤19 years). Data Extraction and Synthesis: This systematic review and meta-analysis was performed following the Preferred Reporting Items for Systematic Review and Meta-analysis and Meta-analysis of Observational Studies in Epidemiology guidelines. Pairs of reviewers independently extracted data and evaluated risk of bias using the Risk of Bias in Nonrandomized Studies of Interventions tool. A meta-analysis was conducted if more than 2 studies evaluated the same intervention-comparator-outcome and controlled minimally for age and injury severity. Subgroup analyses were planned for age, injury type and severity, trauma center designation level and verification body, country, and year of conduct. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) was used to assess certainty of evidence. Main Outcome(s) and Measure(s): Primary outcomes were mortality, complications, functional status, discharge destination, and quality of life. Secondary outcomes were resource use and processes of care, including computed tomography (CT) and operative management of blunt solid organ injury (SOI). Results: A total of 56 studies with 286 051 participants were included overall, and 34 were included in the meta-analysis. When compared with ATCs, PTCs were associated with a 41% lower risk of mortality (OR, 0.59; 95% CI, 0.46-0.76), a 52% lower risk of CT use (OR, 0.48; 95% CI, 0.26-0.89) and a 64% lower risk of operative management for blunt SOI (OR, 0.36; 95% CI, 0.23-0.57). The OR for complications was 0.80 (95% CI, 0.41-1.56). There was no association for mortality for older children (OR, 0.71; 95% CI, 0.47-1.06), and the association was closer to the null when PTCs were compared with CTCs (OR, 0.73; 95% CI, 0.53-0.99). Results remained similar for other subgroup analyses. GRADE certainty of evidence was very low for all outcomes. Conclusions and Relevance: In this systematic review and meta-analysis, results suggested that PTCs were associated with lower odds of mortality, CT use, and operative management for SOI than ATCs for children admitted to hospitals following trauma, but certainty of evidence was very low. Future studies should strive to address selection and confounding biases.

Clinical Practice Guideline Recommendations in Pediatric Orthopaedic Injury: A Systematic Review.

BACKGROUND: Lack of adherence to recommendations on pediatric orthopaedic injury care may be driven by lack of knowledge of clinical practice guidelines (CPGs), heterogeneity in recommendations or concerns about their quality. We aimed to identify CPGs for pediatric orthopaedic injury care, appraise their quality, and synthesize the quality of evidence and the strength of associated recommendations. METHODS: We searched Medline, Embase, Cochrane CENTRAL, Web of Science and websites of clinical organizations. CPGs including at least one recommendation targeting pediatric orthopaedic injury populations on any diagnostic or therapeutic intervention developed in the last 15 years were eligible. Pairs of reviewers independently extracted data and evaluated CPG quality using the Appraisal of Guidelines Research and Evaluation (AGREE) II tool. We synthesized recommendations from high-quality CPGs using a recommendations matrix based on the GRADE Evidence-to-Decision framework. RESULTS: We included 13 eligible CPGs, of which 7 were rated high quality. Lack of stakeholder involvement and applicability (i.e., implementation strategies) were identified as weaknesses. We extracted 53 recommendations of which 19 were based on moderate or high-quality evidence. CONCLUSIONS: We provide a synthesis of recommendations from high-quality CPGs that can be used by clinicians to guide treatment decisions. Future CPGs should aim to use a partnership approach with all key stakeholders and provide strategies to facilitate implementation. This study also highlights the need for more rigorous research on pediatric orthopaedic trauma. LEVEL OF EVIDENCE: Level II-therapeutic study.

Pediatric Moderate and Severe Traumatic Brain Injury: A Systematic Review of Clinical Practice Guideline Recommendations.

Traumatic brain injury (TBI) is the leading cause of death and disability in children. Many clinical practice guidelines (CPGs) have addressed pediatric TBI in the last decade but significant variability in the use of these guidelines persists. Here, we systematically review CPGs recommendations for pediatric moderate-to-severe TBI, evaluate the quality of CPGs, synthesize the quality of evidence and strength of included recommendations, and identify knowledge gaps. A systematic search was conducted in MEDLINE®, Embase, Cochrane CENTRAL, Web of Science, and Web sites of organizations publishing recommendations on pediatric injury care. We included CPGs developed in high-income countries from January 2012 to May 2023, with at least one recommendation targeting pediatric (≤ 19 years old) moderate-to-severe TBI populations. The quality of included clinical practice guidelines was assessed using the AGREE II tool. We synthesized evidence on recommendations using a matrix based on the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. We identified 15 CPGs of which 9 were rated moderate to high quality using AGREE II. We identified 90 recommendations, of which 40 (45%) were evidence based. Eleven of these were based on moderate to high quality evidence and were graded as moderate or strong by at least one guideline. These included transfer, imaging, intracranial pressure control, and discharge advice. We identified gaps in evidence-based recommendations for red blood cell transfusion, plasma and platelet transfusion, thromboprophylaxis, surgical antimicrobial prophylaxis, early diagnosis of hypopituitarism, and mental health mangement. Many up-to-date CPGs are available, but there is a paucity of evidence to support recommendations, highlighting the urgent need for robust clinical research in this vulnerable population. Our results may be used by clinicians to identify recommendations based on the highest level of evidence, by healthcare administrators to inform guideline implementation in clinical settings, by researchers to identify areas where robust evidence is needed, and by guideline writing groups to inform the updating of existing guidelines or the development of new ones.

Clinical practice guideline recommendations for pediatric solid organ injury care: A Systematic Review.

BACKGROUND: Observed variations in the management of pediatric solid organ injuries (SOIs) may be due to difficulty in finding and integrating recommendations from multiple clinical practice guidelines (CPGs) with heterogeneous methodological approaches. We aimed to systematically review CPG recommendations for pediatric SOIs. METHODS: We conducted a systematic review of CPGs including at least one recommendation targeting pediatric SOI populations, using Medical Analysis and Retrieval System Online, Excerpta Medica dataBASE, Web of Science, and websites of clinical organizations. Pairs of reviewers independently assessed eligibility, extracted data, and evaluated the quality of CPGs using the Appraisal of Guidelines Research and Evaluation II tool. We synthesized recommendations from moderate to high-quality CPGs using a recommendations matrix based on Grades of Recommendation, Assessment, Development, and Evaluation criteria. RESULTS: We identified eight CPGs, including three rated moderate or high quality. Methodological weaknesses included lack of stakeholder involvement beyond surgeons, consideration of applicability (e.g., implementation tools), and clarity around the definition of pediatric populations. Five of the 15 recommendations from moderate to high-quality CPGs were based on moderate quality evidence or were rated as strong; these reflected nonoperative management and angioembolization for renal injuries and required length of stay for liver and spleen injuries. CONCLUSION: We identified 15 recommendations on pediatric SOI management from 3 moderate or high-quality CPGs, but only one third were based on at least moderate-quality evidence or were rated as strong. Our results prompt the following recommendations for future CPG development or updates: (1) include all types of clinicians involved in the care of pediatric SOIs and patient and family representatives in the process, (2) develop clear definitions of the target population, and (3) provide advice and tools to promote implementation. Results also underline the urgent need for more rigorous research to support strong evidence-based recommendations in this population. LEVEL OF EVIDENCE: Systematic Review/Meta-analysis; Level III.

Clinical Practice Guideline Recommendations For Pediatric Multisystem Trauma Care: A Systematic Review.

OBJECTIVE: To systematically review clinical practice guidelines (CPGs) for pediatric multisystem trauma, appraise their quality, synthesize the strength of recommendations and quality of evidence, and identify knowledge gaps. BACKGROUND: Traumatic injuries are the leading cause of death and disability in children, who require a specific approach to injury care. Difficulties integrating CPG recommendations may cause observed practice and outcome variation in pediatric trauma care. METHODS: We conducted a systematic review using Medline, Embase, Cochrane Library, Web of Science, ClinicalTrials, and grey literature, from January 2007 to November 2022. We included CPGs targeting pediatric multisystem trauma with recommendations on any acute care diagnostic or therapeutic interventions. Pairs of reviewers independently screened articles, extracted data, and evaluated the quality of CPGs using "Appraisal of Guidelines, Research, and Evaluation II." RESULTS: We reviewed 19 CPGs, and 11 were considered high quality. Lack of stakeholder engagement and implementation strategies were weaknesses in guideline development. We extracted 64 recommendations: 6 (9%) on trauma readiness and patient transfer, 24 (38%) on resuscitation, 22 (34%) on diagnostic imaging, 3 (5%) on pain management, 6 (9%) on ongoing inpatient care, and 3 (5%) on patient and family support. Forty-two (66%) recommendations were strong or moderate, but only 5 (8%) were based on high-quality evidence. We did not identify recommendations on trauma survey assessment, spinal motion restriction, inpatient rehabilitation, mental health management, or discharge planning. CONCLUSIONS: We identified 5 recommendations for pediatric multisystem trauma with high-quality evidence. Organizations could improve CPGs by engaging all relevant stakeholders and considering barriers to implementation. There is a need for robust pediatric trauma research, to support recommendations.

Determining the Agreement Between Common Measures Related to Vestibulo-ocular Reflex Function After a Mild Traumatic Brain Injury in Children and Adolescents.

Objective: To (1) determine the level of agreement between symptom provocation and performance-based tests of vestibulo-ocular reflex (VOR) function after pediatric mild traumatic brain injury (mTBI) and (2) describe the level of symptom provocation induced by a VOR task in individuals with and without cervical findings. Design: Cross-sectional. Setting: This study was conducted at a tertiary care pediatric hospital. Participants: A total of 101 participants (N=101) aged 6-18 years within 3 weeks of mTBI diagnosis were included (54.5% female; mean age, 13.92±2.63 years; mean time since injury at assessment, 18.26±6.16 days). Interventions: None. Main Outcome Measures: Symptom provocation (Vestibular/Ocular Motor Screening tool), performance (clinician-observed VOR performance, head thrust test [HTT], computerized dynamic visual acuity test, video head impulse test), and cervical impairment (cervical flexion-rotation test, range of motion test, self-reported neck pain). Agreement was evaluated using Cohen's κ statistic. Results: No outcomes demonstrated agreement with symptom provocation (κ=-0.15 to 0.14). Fair agreement demonstrated between clinician-observed VOR performance and HTT (κ=0.32), with little to no agreement demonstrated between other measures. Proportions reporting test-induced dizziness and headache were greater among individuals with cervical findings (29.1%-41.8%) than without (2.3%-6.8%). Conclusions: Findings support that symptom provocation and performance-based tests measure different constructs and thus have distinct roles when assessing VOR function. Findings suggest results from measures of symptom provocation may be influenced by coexisting cervical impairments, underlining the value of assessing for cervical injury after pediatric mTBI.

Characterizing the evolution of oculomotor and vestibulo-ocular function over time in children and adolescents after a mild traumatic brain injury.

Background: Impairments to oculomotor (OM) and vestibulo-ocular reflex (VOR) function following pediatric mTBI have been demonstrated but are poorly understood. Such impairments can be associated with more negative prognosis, affecting physical and mental wellbeing, emphasizing the need to more fully understand how these evolve. Objectives: to determine i) the extent to which performance on clinical and computerized tests of OM and VOR function varies over time in children and adolescents at 21 days, 3-, and 6-months post-mTBI; ii) the proportion of children and adolescents with mTBI presenting with abnormal scores on these tests at each timepoint. Design: Prospective longitudinal design. Setting: Tertiary care pediatric hospital. Participants: 36 participants with mTBI aged 6 to18. Procedures: Participants were assessed on a battery of OM and VOR tests within 21 days, at 3- and 6-months post injury. Outcome measures: Clinical measures: Vestibular/ocular motor screening tool (VOMS) (symptom provocation and performance); Computerized measures: reflexive saccade test (response latency), video head impulse test (VOR gain), and dynamic visual acuity test (LogMAR change). Analysis: Generalized estimating equations (parameter estimates and odd ratios) estimated the effect of time. Proportions above and below normal cut-off values were determined. Results: Our sample consisted of 52.8% females [mean age 13.98 (2.4) years, assessed on average 19.07 (8-33) days post-injury]. Older children performed better on visual motion sensitivity (OR 1.43, p = 0.03) and female participants worse on near point of convergence (OR 0.19, p = 0.03). Change over time (toward recovery) was demonstrated by VOMS overall symptom provocation (OR 9.90, p = 0.012), vertical smooth pursuit (OR 4.04, p = 0.03), voluntary saccade performance (OR 6.06, p = 0.005) and right VOR gain (0.068, p = 0.013). Version performance and VOR symptom provocation showed high abnormal proportions at initial assessment. Discussion: Results indicate impairments to the VOR pathway may be present and driving symptom provocation. Vertical smooth pursuit and saccade findings underline the need to include these tasks in test batteries to comprehensively assess the integrity of OM and vestibular systems post-mTBI. Implications: Findings demonstrate 1) added value in including symptom and performance-based measures in when OM and VOR assessments; 2) the relative stability of constructs measured beyond 3 months post mTBI.

The magnitude of parental stress is highly variable following pediatric concussion: using the transactional model of stress to understand parent experiences.

OBJECTIVES: To use the Transactional Model of Stress to understand variations in parental stress following pediatric concussion. METHODS: Mixed-methods design. 49 children with concussion (13.8 ± 2.3 years, nfemales = 27) and their parent (nfemales = 40) were recruited from a specialty clinic. Quantitative data were collected via surveys at the child's initial clinic visit. Qualitative data were collected through an eleven-question, semi-structured interview with 12 parents. Interview questions focused on post-concussion stressors and data were analyzed using thematic analysis. Multivariable linear regression analyzed predictors of parental stress . RESULTS: Ten of the parents interviewed (83%) described the concussion as having a negative overall effect on their stress, while two parents described the overall experience as positive. Coping abilities and other life stressors were described as reasons for varying stress levels. Neurotic and conscientious personality factors and the child's quality of life total score accounted for 45% of the variance in parental stress (R2 = 0.451, F(3,33) = 9.03, p < 0.001). CONCLUSIONS: Parental stress following pediatric concussion is highly variable. The Transactional Model of Stress appears useful to understand this phenomenon. Future studies should investigate interventions to reduce stress for parents experiencing high levels following their child's concussion.

Developing a conceptual framework to identify and classify sources of parental stress following pediatric concussion.

OBJECTIVES: To create a conceptual framework that classifies the various stresses parents experience following their child's concussion. METHODS: Twelve parents of children with concussion completed a semi-structured interview with the lead author. Questions broadly focused on post-concussion stress, with specific probes for caregiving responsibilities, concussion knowledge, and athletic participation. Data were analyzed using thematic analysis. RESULTS: Ten mothers and 2 fathers participated. Five themes stemmed from our analysis: 1) Concussion Knowledge (central theme): stressors related to sources of concussion information; 2) Child Health Factors: stressors related to injury and illness, including concussion; 3) Activity Factors: stressors related to academic and athletic performance; 4) Parent-Injured Child Relationship Factors: stressors related to providing care to the child; and 5) Personal Factors: stressors unrelated to the concussion (e.g. family, social, career, etc.). Child Health Factors was most frequently identified as the primary stressor (n = 9). CONCLUSIONS: Sources of parental stress were varied following pediatric concussion. Issues relating to the child's post-injury dysfunction and the uncertain recovery from concussion were key stressors identified by parents. Moving forward, this framework can be used to ground the development of specific parental stress screening tools and interventions, which may benefit the parent's mental health and the child's clinical recovery.

Evaluation of parent and youth experiences in advisory groups as part of a mental healthcare clinical trial: protocol for a mixed-method study.

INTRODUCTION: Patient engagement in healthcare research is a necessity to ensure that research objectives align with priorities, outcomes and needs of the population under study, and to facilitate ease of implementation and adoption of findings. In clinical trials, there is an increasing focus on patient engagement during the planning and conduct of clinical trials due to the potential for ethical and methodological benefits. As patient engagement in clinical trials increases, there is a need to evaluate the approaches of these activities to contribute evidence on what is most appropriate and successful. The purpose of this study is to evaluate patient engagement processes and the activities of patient partners during and after a paediatric mental healthcare trial. METHODS AND ANALYSIS: Using a mixed-methods study design, we will evaluate patient partners' engagement activities across set time-points during the trial and after trial completion. In this study, the term 'patient partner' is inclusive of two groups of people with lived experience: (1) caregivers (parents, formal/informal caregivers and family), and (2) youth (aged 15-24 years). Engagement will be evaluated using the participant and project questionnaires of the Public and Patient Engagement Evaluation Tool (PPEET), followed sequentially by semi-structured interviews. Quantitative data from the PPEET questionnaire will be analysed and reported using descriptive statistics. Data from open-ended questions from the PPEET questionnaires and semi-structured interviews will be analysed using thematic analysis. ETHICS AND DISSEMINATION: Approval from Athabasca University Research Ethics Board will be obtained for this project. Findings will be disseminated at both academic and public venues whether in-person or online, and using platforms that are caregiver and youth friendly. TRIAL REGISTRATION NUMBER: NCT04902391.

Clinical practice guideline recommendations for pediatric injury care: protocol for a systematic review.

INTRODUCTION: Evidence suggests the presence of deficiencies in the quality of care provided to up to half of all paediatric trauma patients in Canada, the USA and Australia. Lack of adherence to evidence-based recommendations may be driven by lack of knowledge of clinical practice guidelines (CPGs), heterogeneity in recommendations or concerns about their quality. We aim to systematically review CPG recommendations for paediatric injury care and appraise their quality. METHODS AND ANALYSIS: We will identify CPG recommendations through a comprehensive search strategy including Medical Literature Analysis and Retrieval System Online, Excerpta Medica dataBASE, Cochrane library, Web of Science, ClinicalTrials and websites of organisations publishing recommendations on paediatric injury care. We will consider CPGs including at least one recommendation targeting paediatric injury populations on any diagnostic or therapeutic intervention from the acute phase of care with any comparator developed in high-income countries in the last 15 years (January 2007 to a maximum of 6 months prior to submission). Pairs of reviewers will independently screen titles, abstracts and full text of eligible articles, extract data and evaluate the quality of CPGs and their recommendations using Appraisal of Guidelines Research and Evaluation (AGREE) II and AGREE Recommendations Excellence instruments, respectively. We will synthesise evidence on recommendations using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) Evidence-to-Decision framework and present results within a recommendations matrix. ETHICS AND DISSEMINATION: Ethics approval is not a requirement as this study is based on available published data. The results of this systematic review will be published in a peer-reviewed journal, presented at international scientific meetings and distributed to healthcare providers. PROSPERO REGISTRATION NUMBER: International Prospective Register of Systematic Reviews (CRD42021226934).

Higher parental stress is significantly related to longer clinical recovery times in concussed children: A mixed-methods study.

OBJECTIVES: Parental stress and anxiety negatively influences a child's recovery following traumatic brain injury, but these relationships are largely unexplored in a concussion-specific sample. We hypothesized that children with parents experiencing high stress or with pre-existing anxiety would take significantly longer to recover from concussion. DESIGN: Mixed-methods. METHODS: Forty-nine concussed children (13.8 ±â€¯2.3 years, nfemales = 27) and their parents were recruited. Quantitative data were collected using the Perceived Stress Scale (10-item). Qualitative data (n = 12) were collected through a semi-structured interview with the parent. Kaplan-Meier curves and Cox proportional hazard models analyzed the effect of parental stress and anxiety on time in clinic (days between clinic presentation and discharge) and recovery time (days between concussion and clinic discharge). Thematic analysis was used to analyze interview data. RESULTS: Parental anxiety was not significantly related to either the child's time in clinic (P = 0.27) or recovery time (P = 0.41). Conversely, higher perceived parental stress was related to longer recovery time (Hazard Ratio: 2.162, 95% CI: 1.075, 4.348; p = 0.03) for the injured child, with similar results for time in clinic (Hazard Ratio: 1.883, 95% CI: 0.966, 3.668, p = 0.06). During the interview, parents expressed their stress was directly tied to their child's symptoms and overall functioning and varied throughout recovery. CONCLUSIONS: Recovery time is significantly longer in concussed children whose parents are experiencing higher levels of stress, but not pre-existing anxiety, following injury. Parental stress varies throughout recovery, with stress generally higher in the acute post-injury period. Clinicians should monitor parental stress post-concussion when possible.

Feasibility of Early Active Rehabilitation for Concussion Recovery in Youth: A Randomized Trial.

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.

The Stability of Retrospective Pre-injury Symptom Ratings Following Pediatric Concussion.

Objective: To determine the stability of children's retrospective ratings of pre-injury levels of symptoms over time following concussion. Methods: Children and adolescents (n = 3,063) between the ages of 5-17 diagnosed with a concussion by their treating pediatric emergency department (PED) physician within 48 h of injury completed the Post-Concussion Symptom Inventory (PCSI) at the PED and at 1, 2, 4, 8, and 12-weeks post-injury. At each time point, participants retrospectively recalled their pre-injury levels of post-injury symptoms. The PCSI has three age-appropriate versions for children aged 5-7 (PCSI-SR5), 8-12 (PCSI-SR8), and 13-18 (PCSI-SR13). Total scale, subscales (physical, cognitive, emotional, and sleep), and individual items from the PCSI were analyzed for stability using Gini's mean difference (GMD). Results: The mean GMD for total score was 0.31 (95% CI = 0.28, 0.34) for the PCSI-SR5, 0.19 (95% CI = 0.18, 0.20) for the PCSI-SR8, and 0.17 (95% CI = 0.16, 0.18) for the PCSI-SR13. Subscales ranged from mean GMD 0.18 (physical) to 0.31 (emotional) for the PCSI-SR8 and 0.16 (physical) to 0.31 (fatigue) for the PCSI-SR13. At the item-level, mean GMD ranged from 0.13 to 0.60 on the PCSI-SR5, 0.08 to 0.59 on the PCSI-SR8, and 0.11 to 0.41 on the PCSI-SR13. Conclusions: Children and adolescents recall their retrospective pre-injury symptom ratings with good-to-perfect stability over the first 3-months following their concussion. Although some individual items underperformed, variability was reduced as items were combined at the subscale and full-scale level. There is limited benefit gained from collecting multiple pre-injury symptom queries.

Characteristics and outcomes of physical activity interventions for individuals with mild traumatic brain injury: a scoping review protocol.

INTRODUCTION: Traumatic brain injury (TBI) is a major public health problem, and it is estimated that 85% of TBIs are diagnosed as mild and are commonly referred to as a concussion. In adults, symptoms are expected to resolve within 10-14 days after the injury, but up to 15% of individuals continue to have symptoms beyond this period. Recent clinical recommendations suggest the use of physical activity (PA) as a therapy to manage persisting symptoms. However, the recommendations regarding PA lack clarity about important intervention parameters to help clinicians deliver the intervention. The objectives of this scoping review are thus to identify the characteristics, the measurement tools, the health-related outcomes and the reported effectiveness of PA-based interventions for adults with persisting symptoms of a mild TBI (mTBI). METHODS AND ANALYSIS: This scoping review protocol will follow Arksey and O'Malley's six-step iterative process enhanced by another study and will be conducted by a team of researchers and clinical experts. Five databases (MEDLINE, CINAHL, PsycINFO, SPORTDiscuss and Embase), as well as Google, will be searched using an extensive search strategy to capture relevant scientific and grey literature. Articles will be selected if they report on an intervention designed to have an impact on health-related outcomes or participation among individuals having sustained an mTBI. A data extraction form based on the Consensus on Exercise Reporting Template and the Template for Intervention Description and Replication checklists will be created. Quantitative and qualitative data will be analysed accordingly, synthesised and collated in tables. ETHICS AND DISSEMINATION: This scoping review generates new knowledge from published and publicly available literature; thus, an ethical approval is unnecessary to conduct this research. Dissemination of the results will involve all team members in activities aimed to facilitate knowledge uptake among TBI rehabilitation clinical experts locally, nationally and internationally.

Is There an Optimal Time to Initiate an Active Rehabilitation Protocol for Concussion Management in Children? A Case Series.

OBJECTIVE: To estimate the time frame during which initiating an active rehabilitation intervention (aerobic exercise, balance, and sport specific skills) after concussion contributed to improvement in symptoms at follow-up in children and adolescents who are slow to recover (symptoms persisting beyond 2 weeks) from concussion. SETTING: Concussion clinic at a tertiary care pediatric teaching hospital. PARTICIPANTS: A total of 677 children and adolescents with concussion aged 7 to 18 years. DESIGN: Case series of participants starting active rehabilitation less than 2, 2, 3, 4, 5, or 6 or more weeks postconcussion. MAIN MEASURE: Symptom severity measured by the 22-item Post-Concussion Scale (PCS)-revised. RESULTS: All patients experienced significant improvement of symptoms while participating in active rehabilitation, irrespective of the start time postonset. Patients initiating active rehabilitation at 2 (P < .001) or 3 (P = .039) weeks postinjury demonstrated lower symptom severity at follow-up than those starting at 6 weeks or later. Patients starting at 2 weeks had lower symptom severity than patients starting less than 2 (P = .02), 4 (P = .20), or 5 weeks postinjury (P = .04). Lastly, patients starting less than 2 and 6 weeks or more postinjury yielded equivalent outcomes. CONCLUSIONS: The findings support the use of active rehabilitation in children and adolescents who are slow to recover from concussion. Participants starting active rehabilitation less than 2 weeks and up to 6 or more weeks postconcussion demonstrated significant symptom improvements, but improvement was observed in all groups, regardless of the time to start active rehabilitation.

Ottawa Panel Evidence-Based Clinical Practice Guidelines for Structured Physical Activity in the Management of Juvenile Idiopathic Arthritis.

OBJECTIVE: To create guidelines focused on the use of structured physical activity (PA) in the management of juvenile idiopathic arthritis (JIA). DATA SOURCES: A systematic literature search was conducted using the electronic databases Cochrane Central Register of Controlled Trials, MEDLINE (Ovid), EMBASE (Ovid), and Physiotherapy Evidence Database for all studies related to PA programs for JIA from January 1966 until December 2014, and was updated in May 2015. STUDY SELECTION: Study selection was completed independently by 2 reviewers. Studies were included if they involved individuals aged ≤21 years diagnosed with JIA who were taking part in therapeutic exercise or other PA interventions for which effects of various disease-related outcomes were compared with a control group (eg, no PA program or activity of lower intensity). DATA EXTRACTION: Two reviewers independently extracted information on interventions, comparators, outcomes, time period, and study design. The statistical analysis was reported using the Cochrane Collaboration methods. The quality of the included studies was assessed according to the Physiotherapy Evidence Database Scale. DATA SYNTHESIS: Five randomized controlled trials (RCTs) fit the selection criteria; of these, 4 were high-quality RCTs. The following recommendations were developed: (1) Pilates for improving quality of life, pain, functional ability, and range of motion (ROM) (grade A); (2) home exercise program for improving quality of life and functional ability (grade A); (3) aquatic aerobic fitness for decreasing the number of active joints (grade A); and (4) and cardio-karate aerobic exercise for improving ROM and number of active joints (grade C+). CONCLUSIONS: The Ottawa Panel recommends the following structured exercises and physical activities for the management of JIA: Pilates, cardio-karate, home and aquatic exercises. Pilates showed improvement in a higher number of outcomes.
