Disparities in Adherence to Concussion Clinical Care Recommendations in a Pediatric Population

Factors Influencing Length of Care in Physical Therapy After Pediatric and Adolescent Concussion

CONTEXT

Social determinants of health including insurance type, income, race, and ethnicity have been shown to influence the utilization of physical therapy and recovery after an orthopedic injury. The influence of social determinants of health on the utilization of physical therapy and recovery from concussion is not well understood.

DESIGN

Prospective observational registry study in a specialty concussion program.

METHODS

Patients diagnosed with a concussion using the Postconcussion Symptom Inventory and the visio-vestibular examination (VVE) who were also referred to physical therapy were included. The main outcomes of interest were the number of days from referral to initial physical therapy evaluation and the number of physical therapy visits completed. Information related to patients' age, race, ethnicity, sex, insurance type, and Child Opportunity Index was extracted from the registry. Multivariate and univariate regressions were used to assess the associations of each sociodemographic characteristic with the outcomes.

RESULTS

A total of 341 patients diagnosed with concussion between January 2017 and December 2023 met inclusion criteria. The average age was 14.77, and 64% were female. Patients' age, race, ethnicity, insurance type, and Child Opportunity Index were not associated with days to evaluation or length of care in physical therapy. Higher PCSI scores in children under 12 years (coefficient: 0.17, 95% CI, 0.06-0.29) and female sex (coefficient: 1.2, 95% CI, 0.26-2.1) were associated with a longer course of care in physical therapy. Patients with an abnormal VVE score had on average 2.1 more physical therapy visits than those with a normal VVE score (coefficient: 2.1, 95% CI, 0.73-3.5).

CONCLUSIONS

Higher PCSI scores in children, female sex, and higher VVE scores in general predicted a longer course of care in physical therapy. Implementation of a clinical care pathway for concussion care using the PCSI and the VVE may be one strategy to help mitigate systemic factors that might otherwise negatively influence access to physical therapy.

Challenges and Research Opportunities for Integrating Quantitative Electroencephalography Into Sports Concussion Rehabilitation

Although concussion management and return to play/learn decision making focuses on reducing symptoms, there is growing interest in objective physiological approaches to treatment. Clinical and technological advancements have aided concussion management; however, the scientific study of the neurophysiology of concussion has not translated into its standard of care. This expert commentary is motivated by novel clinical applications of electroencephalographic-based neurofeedback approaches (eg, quantitative electroencephalography [QEEG]) for treating traumatic brain injury and emerging research interest in its translation for treating concussion. QEEG's low-cost relative to other brain recording/imaging techniques and precedent in clinical and medical care makes it a potential tool for concussion rehabilitation. Although uncommon, licensed and certified clinicians and medical professionals are implementing QEEG neurofeedback for concussion management within their score of practice. These approaches are not widely adopted nor recommended by professional medical societies, likely because of a limited evidence base of well-designed studies with available standard protocols. Thus, the potential efficacy of QEEG neurofeedback for treating persistent symptoms or cognitive dysfunction after sports-related concussion is unknown. This commentary will update the concussion clinician-scientist on the emerging research, techniques, and disagreements pertaining to the translation of QEEG neurofeedback for concussion management, particularly in the treatment of persistent cognitive difficulties. This commentary will also introduce to readers the fundamentals of how the electroencephalogram may be acquired, measured, and implemented during QEEG neurofeedback. An evidence base of supportive findings from well-designed studies, including those that are retrospective, outcomes-based, and, ultimately, placebo/sham-controlled is recommended prior to considering more widespread adoption of QEEG neurofeedback approaches for treating persistent symptoms or cognitive deficits after sports-related concussion. We review the considerable barriers to this research and clinical implementation, and conclude with opportunities for future research, which will be necessary for establishing the quality and efficacy of QEEG neurofeedback for concussion care.

Exploring racial disparities and inequalities among children and youth with acquired brain injury: a systematic review

PURPOSE

Racial minoritized children and youth with acquired brain injury (ABI) often experience multiple forms of discrimination. The purpose of this systematic review was to understand the racial disparities in health care among children and youth with ABI and their caregivers.

METHOD

Six international databases (Ovid Medline, Embase, Healthstar, Psychinfo, Scopus, and Web of Science) were systematically searched for peer-reviewed articles. Studies were screened by two researchers who also conducted the data extraction and quality appraisal. A narrative synthesis approach was used to analyze the data.

RESULTS

Of the 8081 studies identified in the search, 34 met the inclusion criteria, which involved 838,052 children and youth with brain injuries (or caregivers representing them) across two countries. The following themes were noted in the studies in our review: (1) racial disparities in accessing care (i.e., diagnosis, hospital admission, length of stay, rehabilitation treatment); (2) racial disparities in ABI-related health outcomes (i.e., functional outcomes and mortality rates); and (3) factors affecting racial disparities (i.e., sources in injury, insurance and expenditures, and intersectionality).

CONCLUSIONS

Our findings reveal the concerning racial disparities among children and youth with ABI. Further research should explore solutions for addressing such racial disparities and solutions to address them.

Factors Associated with Loss to Follow-Up in Pediatric Concussion Patients after Initial Visit: A Retrospective Study at a Concussion Clinic

Objective

The objective of this retrospective study is to identify factors associated with loss to follow-up for postconcussion clearance in pediatric patients by comparing loss to follow-up and full clearance patients.

Study design

This retrospective single-center cohort study analyzed 140 consecutive patients at a pediatric concussion clinic of a safety-net hospital for loss to follow-up, defined as not achieving clearance at last appointment. Univariate and multivariate regression models were fit on variables of interest, including demographic, mechanism and severity of concussion, and characteristics of the first evaluation postconcussion and follow-up management.

Results

Of the sample, 40% (n = 56) achieved clearance and 60% (n = 84) were lost to follow-up. Median age was 15 (IQR 11-17), with male predominance (60.7%). Living with a biological parent (OR = 0.145, 95% CI = 0.028-0.760) and sports involvement (OR = 0.256, 95% CI = 0.092-0.764) were protective factors, while being 10 years old or older (OR = 13.466, 95% CI = 2.792-64.958) and attending 2 or fewer follow-up appointments (OR = 19.027, 95% CI = 4.991-72.533) were risk factors for loss to follow-up. No significant differences were found between sex, race, driving distance, type of insurance, and mechanism of injury.

Conclusions

Living with a biological parent and involvement in sports showed to be protective factors for loss to follow-up. Age at time of concussion and number of appointments were risk factors. A "golden window" of 2 appointments was identified, highlighting the need of a strong rapport and engagement in shared decision-making. Future directions include prospective studies implementing strategies targeting adolescents and building a strong patient-provider relationship.

Characteristics of Pediatric Concussion across Different Mechanisms of Injury in 5 through 12-Year-Olds

OBJECTIVE

To investigate characteristics of sport-related concussion (SRC), recreation-related concussion (RRC), and nonsport or recreation-related concussion (non-SRRC) in patients 5 through 12 years old, an understudied population in youth concussion.

STUDY DESIGN

This observational study included patients aged 5 through 12 years presenting to a specialty care concussion setting at ≤28 days postinjury from 2018 through 2022. The following characteristics were assessed: demographics, injury mechanism (SRC, RRC, or SRRC), point of healthcare entry, and clinical signs and symptoms. Kruskal-Wallis and chi-square tests were used to assess group differences. Posthoc pairwise comparisons were employed for all analyses (α = 0.017).

RESULTS

One thousand one hundred forty-one patients reported at ≤28 days of injury (female = 42.9%, median age = 11, interquartile range (IQR) = 9-12) with the most common mechanism being RRC (37.3%), followed by non-SRRC (31.9%). More non-SRRCs (39.6%) and RRC (35.7%) were first seen in the emergency department (P < .001) compared with SRC (27.9%). Patients with RRC and non-SRRC were first evaluated at specialists 2 and 3 days later than SRC (P < .001). Patients with non-SRRC reported with higher symptom burden, more frequent visio-vestibular abnormalities, and more changes to sleep and daily habits (P < .001) compared with RRC and SRC (P < .001).

CONCLUSIONS

In concussion patients 5 through 12 years, RRCs and non-SRRC were more prevalent than SRC, presenting first more commonly to the emergency department and taking longer to present to specialists. Non-SRRC had more severe clinical features. RRC and non-SRRC are distinct from SRC in potential for less supervision at time of injury and less direct access to established concussion health care following injury.

Social Determinants of Health and Health Equity in the Treatment and Rehabilitation of Sport-Related Concussion: A Content Analysis of Intervention Research and Call-To-Action

This review was designed to (1) determine the extent to which the clinical science on sport-related concussion treatment and rehabilitation has considered social determinants of health (SDoH) or health equity and (2) offer recommendations to enhance the incorporation of SDoH and health equity in concussion treatment research and clinical care. The Concussion in Sport Group consensus statement (2023) was informed by two systematic reviews examining prescribed rest or exercise following concussion and targeted interventions to facilitate concussion recovery. We examined 31 studies, including 2,698 participants, from those two reviews. Race (k = 6; 19.4%) and ethnicity (k = 4; 12.9%) of the study samples were usually not reported. Four studies examined ethnicity (i.e., Hispanic), exclusively as a demographic category. Five studies (16.1%) examined race as a demographic category. Three studies (9.7%) examined socioeconomic status (SES; measured as household income) as a demographic category/sample descriptor and one study (3.2%) examined SES in-depth, by testing whether the treatment and control groups differed by SES. Five studies examined an SDoH domain in a descriptive manner and four studies in an inferential/intentional manner. No study mentioned SDoH, health equity, or disparities by name. Many studies (61.3%) excluded participants based on demographic, sociocultural, or health factors, primarily due to language proficiency. The new consensus statement includes recommendations for concussion treatment and rehabilitation that rely on an evidence base that has not included SDoH or studies addressing health equity. Researchers are encouraged to design treatment and rehabilitation studies that focus specifically on underrepresented groups to determine if they have specific and unique treatment and rehabilitation needs, whether certain practical modifications to treatment protocols might be necessary, and whether completion rates and treatment adherence and response are similar.

Community and Patient Features and Health Care Point of Entry for Pediatric Concussion

Importance

Many recent advances in pediatric concussion care are implemented by specialists; however, children with concussion receive care across varied locations. Thus, it is critical to identify which children have access to the most up-to-date treatment strategies.

Objective

To evaluate differences in the sociodemographic and community characteristics of pediatric patients who sought care for concussion across various points of entry into a regional health care network.

Design, Setting, and Participants

This cross-sectional study included children seen for concussions across a regional US health care network from January 1, 2017, to August 4, 2023. Pediatric patients aged 0 to 18 years who received an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Clinical Modification code for concussion were included. The study took place at emergency department (ED) and outpatient (primary care [PC] and specialty care [SC]) settings.

Exposures

Age at visit, biological sex, parent-identified race and ethnicity, payer type, median income and percentage of adults with a bachelor's degree for home zip code, and overall and subdomain Child Opportunity Index (COI) score based on patient address.

Main Outcomes and Measures

The association of exposures with point of entry of ED, PC, and SC were examined in both bivariate analysis and a multinomial logistic regression.

Results

Overall, 15 631 patients were included in the study (median [IQR] age, 13 [11-15] years; 7879 [50.4%] male; 1055 [6.7%] Hispanic, 2865 [18.3%] non-Hispanic Black, and 9887 [63.7%] non-Hispanic White individuals). Race and ethnicity were significantly different across settings (1485 patients [50.0%] seen in the ED were non-Hispanic Black vs 1012 [12.0%] in PC and 368 [8.7%] in SC; P < .001) as was insurance status (1562 patients [52.6%] seen in the ED possessed public insurance vs 1624 [19.3%] in PC and 683 [16.1%] in SC; P < .001). Overall and individual COI subdomain scores were also significantly different between settings (overall COI median [IQR]: ED, 30 [9-71]; PC, 87 [68-95]; SC, 87 [69-95]; P < .001). Race, insurance status, and overall COI had the strongest associations with point of entry in the multivariable model (eg, non-Hispanic Black patients seen in the ED compared with non-Hispanic White patients: odds ratio, 2.03; 95% CI, 1.69-2.45).

Conclusions and Relevance

In this cross-sectional study, children with concussion seen in the ED setting were more likely to be non-Hispanic Black, have public insurance, and have a lower Child Opportunity Index compared with children cared for in the PC or SC setting. This highlights the importance of providing education and training for ED clinicians as well as establishing up-to-date community-level resources to optimize care delivery for pediatric patients with concussion at high risk of care inequities.

Using mobile health to expedite access to specialty care for youth presenting to the emergency department with concussion at highest risk of developing persisting symptoms: a protocol paper for a non-randomised hybrid implementation-effectiveness trial

INTRODUCTION

Paediatric concussion is a common injury. Approximately 30% of youth with concussion will experience persisting postconcussion symptoms (PPCS) extending at least 1 month following injury. Recently, studies have shown the benefit of early, active, targeted therapeutic strategies. However, these are primarily prescribed from the specialty setting. Early access to concussion specialty care has been shown to improve recovery times for those at risk for persisting symptoms, but there are disparities in which youth are able to access such care. Mobile health (mHealth) technology has the potential to improve access to concussion specialists. This trial will evaluate the feasibility of a mHealth remote patient monitoring (RPM)-based care handoff model to facilitate access to specialty care, and the effectiveness of the handoff model in reducing the incidence of PPCS.

METHODS AND ANALYSIS

This study is a non-randomised type I, hybrid implementation-effectiveness trial. Youth with concussion ages 13-18 will be enrolled from the emergency department of a large paediatric healthcare network. Patients deemed a moderate-to-high risk for PPCS using the predicting and preventing postconcussive problems in paediatrics (5P) stratification tool will be registered for a web-based chat platform that uses RPM to collect information on symptoms and activity. Those patients with escalating or plateauing symptoms will be contacted for a specialty visit using data collected from RPM to guide management. The primary effectiveness outcome will be the incidence of PPCS, defined as at least three concussion-related symptoms above baseline at 28 days following injury. Secondary effectiveness outcomes will include the number of days until return to preinjury symptom score, clearance for full activity and return to school without accommodations. The primary implementation outcome will be fidelity, defined as the per cent of patients meeting specialty care referral criteria who are ultimately seen in concussion specialty care. Secondary implementation outcomes will include patient-defined and clinician-defined appropriateness and acceptability.

ETHICS AND DISSEMINATION

This study was approved by the Institutional Review Board of the Children's Hospital of Philadelphia (IRB 22-019755). Study findings will be published in peer-reviewed journals and disseminated at national and international meetings.

Head Injury Treatment With Healthy and Advanced Dietary Supplements: A Pilot Randomized Controlled Trial of the Tolerability, Safety, and Efficacy of Branched Chain Amino Acids in the Treatment of Concussion in Adolescents and Young Adults

Concussion is a common injury in the adolescent and young adult populations. Although branched chain amino acid (BCAA) supplementation has shown improvements in neurocognitive and sleep function in pre-clinical animal models of mild-to-moderate traumatic brain injury (TBI), to date, no studies have been performed evaluating the efficacy of BCAAs in concussed adolescents and young adults. The goal of this pilot trial was to determine the efficacy, tolerability, and safety of varied doses of oral BCAA supplementation in a group of concussed adolescents and young adults. The study was conducted as a pilot, double-blind, randomized controlled trial of participants ages 11-34 presenting with concussion to outpatient clinics (sports medicine and primary care), urgent care, and emergency departments of a tertiary care pediatric children's hospital and an urban tertiary care adult hospital, between June 24, 2014 and December 5, 2020. Participants were randomized to one of five study arms (placebo and 15 g, 30 g, 45 g, and 54 g BCAA treatment daily) and followed for 21 days after enrollment. Outcome measures included daily computerized neurocognitive tests (processing speed, the a priori primary outcome; and attention, visual learning, and working memory), symptom score, physical and cognitive activity, sleep/wake alterations, treatment compliance, and adverse events. In total, 42 participants were randomized, 38 of whom provided analyzable data. We found no difference in our primary outcome of processing speed between the arms; however, there was a significant reduction in total symptom score (decrease of 4.4 points on a 0-54 scale for every 500 g of study drug consumed, p value for trend = 0.0036, [uncorrected]) and return to physical activity (increase of 0.503 points on a 0-5 scale for every 500 g of study drug consumed, p value for trend = 0.005 [uncorrected]). There were no serious adverse events. Eight of 38 participants reported a mild (not interfering with daily activity) or moderate (limitation of daily activity) adverse event; there were no differences in adverse events by arm, with only two reported mild adverse events (both gastrointestinal) in the highest (45 g and 54 g) BCAA arms. Although limited by slow enrollment, small sample size, and missing data, this study provides the first demonstration of efficacy, as well as safety and tolerability, of BCAAs in concussed adolescents and young adults; specifically, a dose-response effect in reducing concussion symptoms and a return to baseline physical activity in those treated with higher total doses of BCAAs. These findings provide important preliminary data to inform a larger trial of BCAA therapy to expedite concussion recovery.

Response Rate Patterns in Adolescents With Concussion Using Mobile Health and Remote Patient Monitoring: Observational Study

Background

A concussion is a common adolescent injury that can result in a constellation of symptoms, negatively affecting academic performance, neurobiological development, and quality of life. Mobile health (mHealth) technologies, such as apps for patients to report symptoms or wearables to measure physiological metrics like heart rate, have been shown to be promising in health maintenance. However, there is limited evidence about mHealth engagement in adolescents with a concussion during their recovery course.

Objective

This study aims to determine the response rate and response rate patterns in concussed adolescents reporting their daily symptoms through mHealth technology. It will also examine the effect of time-, demographic-, and injury-related characteristics on response rate patterns.

Methods

Participants aged between 11-18 years (median days since injury at enrollment: 11 days) were recruited from the concussion program of a tertiary care academic medical center and a suburban school's athletic teams. They were asked to report their daily symptoms using a mobile app. Participants were prompted to complete the Post-Concussion Symptom Inventory (PCSI) 3 times (ie, morning, afternoon, and evening) per day for 4 weeks following enrollment. The primary outcome was the response rate pattern over time (by day since initial app use and the day since injury). Time-, demographic-, and injury-related differences in reporting behaviors were compared using Mann Whitney U tests.

Results

A total of 56 participants were enrolled (mean age 15.3, SD 1.9 years; n=32, 57% female). The median response rate across all days of app use in the evening was 37.0% (IQR 27.2%-46.4%), which was significantly higher than the morning (21.2%, IQR 15.6%-30.5%) or afternoon (26.4%, IQR 21.1%-31.5%; P<.001). The median daily response was significantly different by sex (female: 53.8%, IQR 46.2%-64.2% vs male: 42.0%, IQR 28.6%-51.1%; P=.003), days since injury to app use (participants starting to use the app >7 days since injury: 54.1%, IQR 47.4%-62.2% vs starting to use the app ≤7 days since injury: 38.0%, IQR 26.0%-53.3%; P=.002), and concussion history (participants with a history of at least one prior concussion: 57.4%, IQR 44.5%-70.5% vs participants without concussion history: 42.3%, IQR 36.8%-53.5%; P=.03). There were no significant differences by age. Differences by injury mechanism (sports- and recreation-related injury: 39.6%, IQR 36.1%-50.4% vs non-sports- or recreation-related injury: 30.6%, IQR 20.0%-42.9%; P=.04) and initial symptom burden (PCSI scores greater than the median score of 47: 40.9%, IQR 35.2%-53.8% vs PCSI scores less than or equal to the median score: 31.9%, IQR 24.6%-40.6%; P=.04) were evident in the evening response rates; however, daily rates were not statistically different.

Conclusions

Evening may be the optimal time to prompt for daily concussion symptom assessment among concussed adolescents compared with morning or afternoon. Multiple demographic- and injury-related characteristics were associated with higher daily response rates, including for female participants, those with more than 1 week from injury to beginning mHealth monitoring, and those with a history of at least one previous concussion. Future studies may consider incentive strategies or adaptive digital concussion assessments to increase response rates in populations with low engagement.

Framing racial disparities within sports related concussion (SRC): an ecological framework for understanding biases and disparities in concussion care for black athletes

Privilege and marginalization associated with racial background have been posited as contributors to why Black athletes face disparities within their care, treatment, and recovery from sport-related concussion (SRC). However, empirical findings have limited exploration on how disparate outcomes have emerged, and the interaction with systems of biases, power and disenfranchisement. To understand concussion care disparities, a qualitative content analysis was conducted in three phases: [I] identifying salient literature on racial differences for Black athletes with SRC (N = 29), [II] qualitative analysis of literature to determine salient topics, themes and patterns within the literature, and [III] constructing a novel ecological-systems framework that encapsulates the 'why' and 'how' related to psychosocial and sociocultural experiences of power, access, and biases for Black athletes. The content analysis yielded two patterns, where concussion care decisions are influenced by (1) biased, unconscious beliefs that posit Black athletes as uniquely invincible to injury and pain, and (2) inadequate access to concussion knowledge and resources, which both moderate SRC injury risk, diagnosis, recovery and outcomes. Ultimately, our novel framework provides a clear thread on how historical, macro-level policy and perceptions can impact micro-level clinical care and decision-making for Black athletes with SRC.

A comparison of public views about sports concussion recovery with current guidelines: where are the gaps and overlaps?

Background Sports concussion (SC) management guidelines have recently been updated. A key focus is the emphasis on rest (immediately postinjury) followed by gradual resumption of activity (active recovery). This study aimed to explore community views on SC management and compared these with the guidelines. Methods A total of 157 volunteers completed an online SC survey, including listing three pieces of advice for a concussed person immediately postinjury, and after 2weeks (subacute). Quantitative data were statistically compared, and qualitative data underwent content analysis. Results Almost all participants offered different immediate versus subacute advice; however, rest featured highly at both timepoints. Commonly expressed themes, consistent with guidelines were immediate rest; safety and reinjury prevention; and symptom monitoring. Two themes were identified in the community advice with limited emphasis in the guidelines: general health advice and psychological and social support. Expert clinical assessment was not always identified in community advice. Conclusion Community members hold some views that align with expert advice for SC, particularly the importance of immediate postinjury rest. However, there is scope to grow public awareness of some recommended practices, including expert clinical assessment following injury and when to engage in active recovery.

Categorizing Sports-Related Concussion Disparities by Key Domains of Social Determinants of Health

PURPOSE OF REVIEW

To explore recently published data on disparities in concussion and best categorize these data into domains of social determinants of health (SDOH).

RECENT FINDINGS

Disparities in concussion cover a range of SDOH domains. Questions on disparities in concussion remain. Interventions to reduce these disparities and inequities are needed. Social determinants of health may play a significant role in disparities and inequities in sports related concussion. There is interplay and overlap in SDOH domains that affect concussion outcomes. It is possible that an increase in SDOH may affect concussion disparities by moderated mediation; however, further data is needed to validate this potential effect. Moreover, attention to SDOH domains in sports related concussion may provide insight on intervention targets to ameliorate disparities in sports related concussion.

Racial identity and concussion diagnosis and recovery trajectories in collegiate athletes: a LIMBIC MATARS investigation

OBJECTIVE

To determine if there were concussion diagnosis and recovery disparities between collegiate athletes with Black and White racial identities.

DESIGN

Retrospective cohort study.

METHODS

Concussion information was extracted from NCAA athlete medical files at LIMBIC MATARS member institutions from the 2015-16' to 2019-20' academic years. A total of 410 concussions from 9 institutions were included that provided all independent (i.e. racial identity of Black or White) and dependent variable information (i.e. dates of injury, diagnosis, symptom resolution, and return to sport) that were analyzed using Mann-Whitney U tests. The sample consisted of 114 (27.8%) concussions sustained by Black athletes and 296 (72.1%) sustained by White athletes.

RESULTS

The overall sample had a median of 0 days between injury occurrence to diagnosis, 7 days to symptom resolution, and 12 days to return to sport. No significant timing differences were observed for concussion diagnosis (p = .14), symptom resolution (p = .39), or return to sport (p = 0.58) between collegiate athletes with Black versus White racial identities.

CONCLUSIONS

These findings may reflect equitable access to onsite sports medicine healthcare resources that facilitate concussion management in the collegiate sport setting. Future work should explore these associations with a larger and more diverse sample of collegiate athletes.

Investigation of Factors Contributing to Racial Differences in Sport-Related Concussion Outcomes

OBJECTIVE

Following sport-related concussion (SRC), early studies have demonstrated racial differences in time to clinical recovery; however, these differences have not been fully explained. We sought to further explore these associations by considering possible mediating/moderating factors.

METHODS

Data from patients aged 12-18 years diagnosed with SRC from November 2017 to October 2020 were analyzed. Those missing key data, lost to follow-up, or missing race were excluded. The exposure of interest was race, dichotomized as Black/White. The primary outcome was time to clinical recovery (days from injury until the patient was either deemed recovered by an SRC provider or symptom score returned to baseline or zero.) RESULTS: A total of 389 (82%) White and 87 (18%) Black athletes with SRC were included. Black athletes more frequently reported no SRC history (83% vs. 67%, P = 0.006) and lower symptom burden at presentation (median total Post-Concussion Symptom Scale 11 vs. 23, P < 0.001) than White athletes. Black athletes achieved earlier clinical recovery (hazard ratio [HR] = 1.35, 95% CI 1.03-1.77, P = 0.030), which remained significant (HR = 1.32, 95% CI 1.002-1.73, P = 0.048) after adjusting for confounders associated with recovery but not race. A third model adding the initial Post-Concussion Symptom Scale score nullified the association between race/recovery (HR = 1.12, 95% CI 0.85-1.48, P = 0.410). Adding prior concussion history further reduced the association between race/recovery (HR = 1.01, 95% CI 0.77-1.34, P = 0.925).

CONCLUSIONS

Overall, Black athletes initially presented with fewer concussion symptoms than White athletes, despite no difference in time to clinic. Black athletes achieved earlier clinical recovery following SRC, a difference explained by differences in initial symptom burden and self-reported concussion history. These crucial differences may stem from cultural/psychologic/organic factors.

The effect of a home exercise program on visio-vestibular function in concussed pediatric patients

Background

A visio-vestibular home exercise program (VV-HEP) can provide an equitable and cost-effective method for therapy targeted towards visio-vestibular deficits that are common following concussion. The effects of a VV-HEP on improving concussion symptoms and visio-vestibular function are unclear.

Purpose

Determine the effect of VV-HEP on symptoms and visio-vestibular function in concussed pediatric patients.

Methods

This study included 527 patients [294 female (55.8%); age = 14.4 ± 2.1 years] reporting to a specialty care concussion center within 28 days of injury and for a first follow-up within 60 days of injury. Patients completed the Post-Concussion Symptom Inventory (PCSI) and Visio-Vestibular Examination (VVE). Patients were prescribed the VV-HEP at initial visit, with exercises including saccades, gaze stability, convergence, and balance, and instructed to complete these 1-2 times/day. At follow-up, patients self-reported their VV-HEP progress as (1) has not done, (2) in progress, or (3) completed. Primary outcomes included VV-HEP progress at follow-up, PCSI endorsement and severity, VVE subtests (normal/abnormal), and total VVE score (abnormal = 2 + abnormal subtests). Kruskal-Wallis tests and chi-square were used to determine if concussion symptoms or the proportion of abnormal VVE outcomes, respectively, were associated with VV-HEP status. Post-hoc pairwise comparisons with Bonferonni corrections were used to determine concussion symptom (α = 0.017 a priori) and VVE (α = 0.005 a priori) differences in VV-HEP status.

Results

At follow-up, patients who had completed the VV-HEP reported lower symptom endorsement (median = 1, IQR = 0-3) and lower symptom severity (median = 1, IQR = 0-4) relative to patients who had not started the VV-HEP (endorsement median = 7, IQR = 1-13, p < 0.0001; severity median = 15.5, IQR = 2-32.5, p < 0.0001) and those in progress (endorsement median = 8, IQR = 3-14, p < 0.0001; severity median = 15, IQR = 4-30, p < 0.0001). A lower proportion of patients who completed the VV-HEP reported with abnormal vestibular-ocular reflex (22.2%), tandem gait (0%), and total VVE score (22.2%) relative to those who had not started or those in progress (p < 0.005).

Conclusion

Our findings indicate that patients who completed the VV-HEP had lower symptom burden and improved visio-vestibular function relative to those who did not start or were in progress. This suggests that a VV-HEP can effectively reduce visio-vestibular dysfunction following concussion and may serve as a means to minimize inequities in access to care.
