SCAT5 Sex Differences: Normative Data, Clinical Thresholds, and Relevance for Identification of Concussion.

OBJECTIVE: This study evaluated sex differences in performance on the Sport Concussion Assessment Tool-5 (SCAT5) Standardized Assessment of Concussion (SAC) and in baseline SCAT5 symptom reporting. It established clinically relevant cut points for low performance on the SAC based on both reliable chance indices (RCIs) and normative performance. This study also evaluated the diagnostic utility of the sex-adjusted SCAT5 SAC for identification of suspected concussion in collegiate athletes. METHOD: In total, 671 uninjured collegiate athletes were administered the SCAT5 and 264 of these athletes also completed SCAT5 testing ~1 year later. Fifty-four athletes were administered the SCAT5 after being removed from play due to suspected concussion. Sex differences in cognitive performance and symptom reporting at baseline were evaluated and sex-specific clinically relevant cut points were provided. Chi square and logistic regression models were used to evaluate if SAC performance was a significant predictor of concussion status. RESULTS: Female athletes outperformed male athletes on the SCAT 5 SAC and showed minimally higher symptom endorsement. Use of sex-corrected normative data improved performance of the SAC in identification of suspected concussion when a low score cut point was used. Logistic regression models showed that sex-corrected SAC change from baseline (RCI) improved the predictive value of the model after first accounting for other elements of the SCAT5. CONCLUSIONS: Present results support the use of sex-specific normative data for the SCAT5 SAC, particularly if using low performance without comparison to a baseline; however, reliable change from a pre-injury baseline may have somewhat higher diagnostic utility.

Return to Activity After SARS-CoV-2 Infection: Cardiac Clearance for Children and Adolescents.

CONTEXT: Sedentary behavior and inability to participate in organized physical activity has negatively affected the physical and mental health of children and adolescents; however, cardiac injury and associated risk for sudden cardiac death with return to activity remains a major concern. Guidelines have been proposed for return to activities; however, these fail to address the needs of younger children and those participating in more casual activities. Guidance is needed for primary care providers to facilitate safe return to everyday activity and sports and to help direct appropriate laboratory, electrocardiographic, and anatomical assessment. EVIDENCE ACQUISITION: Review of computerized databases of available literature on SARS-CoV-2 infection in children and postinfection sequelae, risk factors for sudden cardiac death, and previous return to play recommendations. STUDY DESIGN: Clinical guidelines based on available evidence and expert consensus. LEVEL OF EVIDENCE: Level 4. RESULTS: In this report, we review the literature on return to activity after SARS-CoV-2 infection and propose recommendations for cardiac clearance for children and adolescents. Though severe disease and cardiac injury is less common in children than in adults, it can occur. Several diagnostic modalities such as electrocardiography, echocardiography, cardiac magnetic resonance imaging, and serologic testing may be useful in the cardiac evaluation of children after SARS-CoV-2 infection. CONCLUSION: Gradual return to activity is possible in most children and adolescents after SARS-CoV-2 infection and many of these patients can be cleared by their primary care providers. Providing education on surveillance for cardiopulmonary symptoms with return to sports can avoid unnecessary testing and delays in clearance.

Musculoskeletal and Sports Medicine Curriculum Guidelines for Pediatric Residents.

ABSTRACT: Musculoskeletal (MSK) and sports-related conditions are relatively common in the pediatric population. Pediatric residencies should provide residents with the knowledge and skills to assess and manage both acute and chronic MSK and sports injuries and complaints. Residents should develop the competencies and attitudes to safeguard and promote a healthy and active lifestyle for youth. Programs can use a variety of educational tools, both in the clinic and on the field, to provide a well-rounded MSK curriculum throughout the residency years. This article provides a review of general pediatric sports medicine curriculum guidelines and suggested implementation strategies.

Multidisciplinary Concussion Management: A Model for Outpatient Concussion Management in the Acute and Post-Acute Settings.

OBJECTIVE: To describe a model of multidisciplinary concussion management and explore management methods in the acute and post-acute settings. SETTING: A multidisciplinary concussion management program within a large health system. PARTICIPANTS: Patients with sports and non-sports-related concussions aged 14 to 18 years with persisting concussion symptoms at 4 weeks postinjury or beyond. DESIGN: Pilot randomized controlled trial comparing a subsymptom threshold exercise program with standard-of-care treatment in the post-acute setting. MAIN MEASURES: Beck Depression Inventory-II and the Post-Concussion Scale-Revised. RESULTS: Across groups, 60% improvement in concussion symptoms was noted. After removing the influence of depression, the intervention showed a large effect on symptom reduction, with participants in the intervention group improving more than those in the control group. There was no difference in response to the intervention by the sports and nonsports groups. CONCLUSION: Results demonstrate that exercise intervention is effective in reducing symptoms in adolescents with persisting symptoms. The finding that participants in the control group who underwent education, light activity, and sophisticated monitoring still had meaningful recovery supports the utility of active engagement in a multidisciplinary management program. Finally, depression had a clinically meaningful effect on recovery, highlighting the need for targeted intervention of noninjury factors relevant to persisting symptoms.

The Pediatric Endurance Athlete.

Youth sports participation numbers continue to grow in the United States. A shift toward sport specialization has caused an increase in sport training frequency and intensity that places the growing athlete at risk for overtraining, nutritional deficits, and injuries. Individuals who participate in endurance sports are at especially high risk. Youth runners and swimmers are high-risk populations that require special attention to their training schedules, nutritional intake, and injuries. Appropriate scheduling of training, dedicating time to rest, and nutrition education can help prevent problems in the endurance athlete.

Bilateral knee pain in a high-level gymnast.

Gymnast wrist or distal radial physeal injury is a common entity among gymnasts of all levels. It can lead to chronic pain, inability to perform, and growth issues at the wrist for these young athletes. However, less has been reported about other overuse stress injuries in this group. We present the case of a prepubescent female gymnast complaining of chronic bilateral knee pain. She was found to have bilateral distal femoral physeal stress injuries and had a similar clinical course to any gymnast diagnosed with the same injury at the wrist.

Injuries and medical issues in softball.

Softball is enjoyed by millions of female and male athletes of all ages and competitive levels. Windmill pitchers are at risk for developing overuse injuries in the throwing arm. Improper mechanics and lack of pitch counts may increase the risk for developing a pitching-related injury. Softball-related overuse injuries include proximal biceps tendinitis, upper extremity stress fractures, and ulnar neuritis. Acute injuries commonly occur in the lower extremity and include both fractures and ligamentous injuries. Sliding injuries account for a significant number of these lower extremity injuries. The addition of breakaway bases and mandatory use of protective headgear by defensive players may decrease acute injuries commonly seen in softball. Off-season programs should stress proper throwing and sliding mechanics, core conditioning, and a lower extremity neuromuscular education program.

Trampoline safety in childhood and adolescence.

Despite previous recommendations from the American Academy of Pediatrics discouraging home use of trampolines, recreational use of trampolines in the home setting continues to be a popular activity among children and adolescents. This policy statement is an update to previous statements, reflecting the current literature on prevalence, patterns, and mechanisms of trampoline-related injuries. Most trampoline injuries occur with multiple simultaneous users on the mat. Cervical spine injuries often occur with falls off the trampoline or with attempts at somersaults or flips. Studies on the efficacy of trampoline safety measures are reviewed, and although there is a paucity of data, current implementation of safety measures have not appeared to mitigate risk substantially. Therefore, the home use of trampolines is strongly discouraged. The role of trampoline as a competitive sport and in structured training settings is reviewed, and recommendations for enhancing safety in these environments are made.
