OBJECTIVE: Little is known about the prognostic value of the Buffalo Concussion Treadmill Test (BCTT) after the acute phase of sport-related concussion (SRC). We examined the added prognostic value of the BCTT performed 10 to 21 days after SRC in children, in addition to participant, injury, and clinical process characteristics on days to recovery. DESIGN: Historical clinical cohort study. SETTING: Network of approximately 150 Canadian multidisciplinary primary-care clinics...

This case report highlights a rare type of primary spinal cord tumor, myxopapillary ependymoma, in a pediatric patient who presented to clinic with worsening chronic unilateral thigh pain and neurologic deficits. He was appropriately treated with total gross resection of the tumor and adjuvant radiotherapy and was cleared for competitive sports without any restriction within 1 year of his diagnosis and treatment. Although most musculoskeletal complaints among pediatric patients are of benign etiology, as evidenced by our case, clinicians should have a low threshold to further investigate with advanced imaging modalities should the clinical history and examination be consistent with a more concerning pathologic process...

SETTINGS: Six children's hospital-based medical centers and 9 secondary school athletic training facilities. PATIENTS: Pediatric patients (8-18 years) were enrolled as part of the Sport Concussion Outcomes in Pediatrics (SCOPE) study during their initial visit for a diagnosis of sport-related concussion...

OBJECTIVE: To describe the epidemiology of field hockey-related injuries of patients aged 6 to 24 years who were treated in US emergency departments from 2000 to 2020. DESIGN: The researchers conducted a retrospective analysis using data from the National Electronic Injury Surveillance System (NEISS). SETTING: The NEISS collects data on recreational activity-related and consumer product-related injuries treated in US Eds. PATIENTS: Patients aged 6 to 24 years who were treated for field hockey-related injuries in Eds from 2000 to 2020...

OBJECTIVE: To describe the presentation and management of lumbar bone stress injuries (LBSI), recurrent LBSI, and lumbar nonunited defects in elite Australian male and female cricket players. DESIGN: Retrospective case series. SETTING: Professional domestic and international cricket teams over 13 seasons. PARTICIPANTS: Elite Australian cricket players. INDEPENDENT VARIABLES: Symptomatic LBSI requiring time off cricket and lumbar nonunited defects, both confirmed by imaging...

OBJECTIVE: To compare dual-energy x-ray absorptiometry (DXA) and bioelectric impedance analysis (BIA) in the assessment of body composition in athletes. DATA SOURCES: A systematic review and meta-analysis was conducted collating peer-reviewed studies that compared BIA with DXA for the assessment of body composition in athletes that indexed in MEDLINE, CINAHL, EMBASE, and PsycINFO databases. MAIN RESULTS: After duplicate removal, 267 articles remained for full-text screening...

OBJECTIVE: To establish normative baseline values on the King-Devick (KD) Test for contact wheelchair sport participants. The secondary purpose was to examine the effect of physical exertion on test score. DESIGN: Quasiexperimental. SETTING: Competitive disability sport venues before practices or games. PARTICIPANTS: One-hundred 43 wheelchair rugby or wheelchair basketball (WBB) players completed the study. Participants were predominantly men (87...

OBJECTIVE: To describe injury mechanisms and magnetic resonance imaging (MRI) findings in acute rectus femoris (RF) injuries of soccer players using a systematic video analysis. DESIGN: Descriptive case series study of consecutive RF injuries from November 2017 to July 2022. SETTING: Two specialized sports medicine hospitals. PARTICIPANTS: Professional male soccer players aged between 18 and 40 years, referred for injury assessment within 7 days after a RF injury, with an available video footage of the injury and a positive finding on an MRI...

OBJECTIVE: To help address the high concussion burden in Canadian youth ice hockey, our primary objective was to examine the concurrent validity of youth ice hockey referees' ability to assess head contacts (HCs) and associated penalties using video analysis methods after implementation of the "zero tolerance for HC" policy by Hockey Canada. STUDY DESIGN: Cross-sectional study. PARTICIPANTS: Certified Level II-III referees in Alberta, Canada...

OBJECTIVE: Perform a systematic literature review regarding return to sport (RTS) outcomes after arthroscopic rotator cuff repair (aRCR) for full-thickness rotator cuff tears (FTRCTs). DATA SOURCES: Systematic review of all articles in PubMed, Medline, and Excerpta Medica Database (EMBASE) was conducted in April 2022 using a combination of keywords: "rotator cuff repair," "RCR," "complete," "full-thickness," "tear," "RCT," "injury," "shoulder," "arthroscopic," "return to sport," "RTS," "sport," "return to play," and "athlete...

OBJECTIVE: To determine whether concomitant psychiatric diagnoses and medication use were associated with postfasciotomy outcomes in patients with chronic exertional compartment syndrome (CECS).
