Persistent post-concussion symptoms include neural auditory processing in young children.

Aim: Difficulty understanding speech following concussion is likely caused by auditory processing impairments. We hypothesized that concussion disrupts pitch and phonetic processing of a sound, cues in understanding a talker.

Patients & Methods/results: We obtained frequency following responses to a syllable from 120 concussed and 120 control.

The Effects of Injury Type on Health-Related Quality of Life in Youth Athletes: A Cross-Sectional Analysis.

Objective: The relationship between health-related quality of life (HRQoL) and injury type has not been analyzed for young athletes. We hypothesized that there would be no difference in HRQoL between injured athletes, injured nonathletes, and normative data for healthy youth (NDHY) or among athletes with acute, overuse, or concussion injuries.

Design: Cross-sectional clinical cohort.

Injury Patterns in Highly Specialized Youth Athletes: A Comparison of 2 Pathways to Specialization.

Context: Sport specialization, commonly defined as intensive year-round training in a single sport to the exclusion of other sports, has been associated with an increased risk for overuse injury. Two pathways to becoming highly specialized are recognized: (1) having only ever played 1 sport (exclusive highly specialized) and (2) quitting other sports to focus on a single sport (evolved highly specialized). Understanding the differences in injury patterns between these groups of highly specialized athletes will inform the development of injury-prevention strategies.

Assessment of post-concussion emotional symptom load using PCSS and PROMIS instruments in pediatric patients.

Objectives: The purpose of this study is to evaluate the utility of the Patient-Reported Outcomes Measurement Information System (PROMIS) anxiety and depressive symptom domains in conjunction with the Post-Concussion Symptom Scale (PCSS)for identifying pediatric patients with emotional symptoms following a concussion, and to identify predictors of higher emotional symptom loads.

Methods: We recruited English-speaking patients aged 8-17 years presenting to a tertiary-care concussion clinic from 2014 to 2018 ( = 458). Demographics and clinical data including PCSS, injury date, previous history of anxiety/depression, and Vestibular/Ocular-Motor Screen (VOMS) were collected from patients' electronic medical records.

Rhythmic gymnasts' injuries in a pediatric sports medicine clinic in the United States: a 10-year retrospective chart review.

Objectives: Rhythmic gymnastics injuries have not been studied thoroughly especially in the United States. Existing research studies are predominantly from Europe or Canada or from more than 15 years ago. The purpose of our study was to provide an updated description of injury patterns among rhythmic gymnasts in the United States.

Eye Movements Detect Differential Change after Participation in Male Collegiate Collision versus Non-Collision Sports.

Although neuroimaging studies of collision (COLL) sport athletes demonstrate alterations in brain structure and function from pre- to post-season, reliable tools to detect behavioral/cognitive change relevant to functional networks associated with participation in collision sports are lacking. This study evaluated the use of eye-movement testing to detect change in cognitive and sensorimotor processing among male club collegiate athletes after one season of participation in collision sports of variable exposure. We predicted that COLL (High Dose [hockey],  = 8; Low Dose [rugby],  = 9) would demonstrate longer reaction times (antisaccade and memory-guided saccade [MGS] latencies), increased inhibitory errors (antisaccade error rate), and poorer spatial working memory (MGS spatial accuracy) at post-season, relative to pre-season, whereas non-collision collegiate athletes (NON-COLL;  = 17) would remain stable.

Youth Athlete Development Models: A Narrative Review.

Context: Physical activity has shown to be beneficial for the overall physical and mental health of youth. There has been an increasing focus on youth sports moving from a recreational activity to becoming a launching pad for participation at elite levels. Several models of athlete development have emerged to guide specialized and nonspecialized athletes at an age-appropriate level, taking into consideration their physical and mental development.

Contributions of PCSS, BESS, Tandem Gait, and Romberg Test for Identifying Balance Deficits in Pediatric Concussions.

Objective: Balance deficits are common after concussions in pediatric patients. This study evaluates 3 clinical tools for identifying postconcussion balance deficits in a pediatric population: (1) Post-Concussion Symptom Scale (PCSS); (2) Balance Error Scoring System (BESS); and (3) physical examination measures of balance: tandem gait (TG) and Romberg test.

Setting: Data were collected in a tertiary care outpatient pediatric sports medicine clinic.

This document provides an overview of selected medical issues important to team physicians who are responsible for athletes with sports-related concussion (SRC). This statement was developed by the Team Physician Consensus Conference (TPCC), an annual project-based alliance of six major professional associations.

Boys gymnastics injuries: A 9-year retrospective review.

Objectives: Young male gymnasts are a frequently injured, yet infrequently studied population. Literature on gymnastics injuries has focused primarily on female gymnasts at elite and collegiate levels. Gymnastics equipment, rules, and training methods have continued to evolve over the past few decades so the previous data likely does not reflect current injury patterns.

Roundtable on Preseason Heat Safety in Secondary School Athletics: Heat Acclimatization.

Objective: To provide best-practice recommendations for developing and implementing heat-acclimatization strategies in secondary school athletics.

Data Sources: An extensive literature review on topics related to heat acclimatization and heat acclimation was conducted by a group of content experts. Using the Delphi method, action-oriented recommendations were developed.

Contributions of PCSS, CISS, and VOMS for Identifying Vestibular/Ocular Motor Deficits in Pediatric Concussions.

Background: Vestibular/ocular motor dysfunction can occur in pediatric concussions, which can impair reading, learning, and participation in athletics. This study evaluated 3 clinical tools for identifying postconcussion vestibular/ocular motor dysfunction: (1) Post-Concussion Symptom Scale (PCSS), (2) Convergence Insufficiency Symptom Survey (CISS), and (3) Vestibular/Ocular Motor Screening (VOMS).

Hypothesis: Evaluating vestibular/ocular motor dysfunction with multiple clinical tools will capture more symptomatic patients than any 1 tool alone.

Defining a Research Agenda for Youth Sport Specialization in the United States: The AMSSM Youth Early Sport Specialization Summit.

Sport specialization is becoming increasingly common among youth and adolescent athletes in the United States and many have raised concern about this trend. Although research on sport specialization has grown significantly, numerous pressing questions remain pertaining to short- and long-term effects of specialization on the health and well-being of youth, including the increased risk of overuse injury and burnout. Many current elite athletes did not specialize at an early age.

Impact of youth sports specialisation on career and task-specific athletic performance: a systematic review following the American Medical Society for Sports Medicine (AMSSM) Collaborative Research Network's 2019 Youth Early Sport Specialisation Summit.

Objective: The impact, positive or negative, of youth sport specialisation (YSS) on short-term and long-term performance is not fully understood; however, the desire to maximise performance goals is generally considered the primary reason children and adolescents specialise at a young age. We performed a systematic review of original research to establish the association of YSS and task-focused or career-focused performance outcomes.

Design: Systematic review.

Consensus Statement on Sports-Related Concussions in Youth Sports Using a Modified Delphi Approach.

Importance: Given the importance of sports-related concussions among youth athletes, the rapid progress of research on this topic over the last decade, and the need to provide further guidance to youth athletes, their families, medical professionals, and athletic personnel and organizations, a panel of experts undertook a modified Delphi consensus process to summarize the current literature and provide recommendations regarding the prevention, assessment, and management of sports-related concussions for young athletes.

Methods: A consensus panel of 11 experts was created to represent a broad spectrum of expertise in youth sports and concussions. The specific questions to be addressed were developed through an iterative process consisting of 3 rounds, and a review of the literature was conducted to identify research studies related to each question.

Performance on auditory, vestibular, and visual tests is stable across two seasons of youth tackle football.

: Few studies have tracked neurologic function in youth football players longitudinally. This study aimed to determine whether changes in tests of auditory, vestibular, and/or visual functions are evident after participation in one or two seasons of youth tackle football.: Prospective cohort study.

Evaluating a Commonly Used Tool for Measuring Sport Specialization in Young Athletes.

Context: Sport specialization has been defined as year-round intensive training in a single sport to the exclusion of other sports. A commonly used survey tool created by Jayanthi et al, which classifies athletes as having a low, moderate, or high level of specialization, categorizes only athletes answering to "Have you quit other sports to focus on a main sport?" as highly specialized. We hypothesized that a measureable number of year-round, single-sport athletes have never played other sports and, therefore, may be inaccurately classified as moderately specialized when using this tool, even though most experts would agree they should be viewed as highly specialized.

Sports Specialization Is Not Associated With Greater Odds of Previous Injury in Elite Male Youth Soccer Players.

Objective: To determine the relationship between sport specialization and previous injury in elite male youth soccer players.

Design: Retrospective survey.
