DESIGN: A three-year, quasi-experimental, prospective cohort (clinicaltrials...

CONTEXT: Medical disqualification (MDQ) following concussion is a challenging decision clinicians may encounter with little evidence-based guidance. OBJECTIVE: We aimed to 1) describe the MDQ following concussion cases athletic trainers (ATs) have been involved in, 2) describe beliefs about MDQ following concussion, and 3) explore factors that ATs believed should be involved in the MDQ following concussion process. DESIGN: Mixed methods. SETTING: Online cross-sectional survey with follow-up semi-structured interviews...

CONTEXT: Little information exists regarding what exertional heatstroke (EHS) survivors know and believe about EHS best practices. Understanding this would help clinicians focus educational efforts to ensure survival and safe return-to-play following EHS. OBJECTIVE: We sought to better understand what EHS survivors knew about EHS seriousness (e.g., lethality, short- and long-term effects), diagnosis and treatment procedures, and recovery. Design: Multi-year, cross-sectional, descriptive design...

CONTEXT: Femoroacetabular impingement syndrome (FAIS) causes pain and functional limitations. Little is known regarding walking characteristics, volume and intensity evaluated in laboratory and free-living conditions and whether these measures differ between those with FAIS and uninjured individuals. OBJECTIVE: To examine the differences in laboratory gait measures and free-living step-based metrics between individuals with FAIS and uninjured control participants...

Two long-distance runners developed MTSS (male age=26.3 years, female age=47.5 years) after baseline assessment of plantar flexor muscle structure and function and spatiotemporal running variables. B-mode ultrasound and lean leg girth characterized plantar flexor muscle structure. Hand-held dynamometry and a single-leg heel raise to failure protocol characterized plantar flexor muscle function. Finally, spatiotemporal running variables were determined during a treadmill protocol. The two runners who developed MTSS demonstrated less plantar flexor strength and endurance capacity than published comparative control data and marked variability in muscle structure...

OBJECTIVE: To synthesize the best available evidence regarding the perceptions and current clinical practices of athletic trainers (ATs) in integrating psychological skills into patient management. DATA SOURCES: PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL) (via EBSCOhost), PsycInfo (via EBSCOhost), SPORTDiscus (via EBSCOhost), Scopus (via Elsevier). STUDY SELECTION: Studies had to investigate the current clinical practices and perceptions of certified ATs in integrating psychologically informed practice for patient management...

CONTEXT: ACL reconstruction (ACLR) patients commonly adopt poor movement patterns that potentially place them at an increased risk for reinjury if untreated. Limb loading characteristics during functional tasks can highlight movement compensations. OBJECTIVE: Examine loading symmetry during a bilateral bodyweight squatting task between sexes, compare loading metrics between limbs and sexes, and describe the relationship between loading metrics and patient reported outcomes (PROs) following ACLR...

CONTEXT: Baseball pitching requires fast and coordinated motions of the whole body to reach high ball speeds, putting considerable strain on the musculoskeletal system, particularly the shoulder and elbow. DESIGN: Descriptive epidemiology study. OBJECTIVE: To describe musculoskeletal symptoms and the functional status of the shoulder and elbow in male high school baseball pitchers. SETTING: Dutch baseball talent academies...

There are two largely competing models for an athletics organization at both the collegiate and professional levels: the High Performance Model and the Medical Model. The High Performance Model arises from international Football perspective that places a "Performance Director" at the center of teams supporting the athletes. The Medical Model, supported by both the National Athletic Trainers Association and the NCAA, separates off medical staff (athletic trainers, physical therapists, and physicians, predominantly) and emphasizes the autonomy of medical decisions...

CONTEXT: Athletic trainers (ATs) face organizational-professional conflict (OPC), often surrounding return-to-sport decisions. To prioritize patient safety and establish a healthy work environment, OPC must be mitigated, yet little research has determined how ATs manage conflicts with stakeholders. OBJECTIVE: To explore ATs' experiences with OPC in the secondary school setting. DESIGN: Qualitative study. SETTING: Telephone interviews...

CONTEXT: People with patellofemoral pain (PFP) may have lower performance during the forward step-down and single-leg hop with their painful (unilateral complaints) or most painful (bilateral complaints) limb when compared to pain-free controls. Yet, no study has investigated the appropriateness of using the pain-free/less painful limb as a reference standard in clinical practice or whether deficits might be present depending on the laterality of pain. OBJECTIVE: To compare performance scores and proportion of side-to-side limb symmetry during the forward step-down and single-leg hop tests among people with unilateral and bilateral PFP, and pain-free controls...

CONTEXT: Slower habitual walking speed and aberrant gait biomechanics are linked to clinically significant knee-related symptoms and articular cartilage composition changes linked to posttraumatic osteoarthritis (PTOA) following anterior cruciate ligament reconstruction (ACLR). OBJECTIVE: To determine specific gait biomechanical variables that can accurately identify individuals with clinically significant knee-related symptoms post-ACLR, and the corresponding threshold values, sensitivity, specificity, and odds ratios for each biomechanical variable...

CONTEXT: Concussion assessment in adapted and para-sport athletes has continued to evolve with growing considerations in para-sports, but little is known about vestibular/ocular performance assessment in this sample. OBJECTIVE: To examine baseline performance on the Vestibular/Ocular Motor Screening (VOMS) in collegiate adapted athletes. A secondary objective was to investigate the role of sex, history of concussion, and functional classification on baseline measures...

CONTEXT: Chronic ankle instability (CAI) is prevalent amongst individuals who sustain a lateral ankle sprain (LAS) injury. The persistent of the characteristic long-standing clinical symptoms of CAI maybe attributable to the lack of adoption of evidence-informed clinical guidelines. OBJECTIVE: To investigate to what extent French-speaking physiotherapists implement the International Ankle Consortium Rehabilitation-Oriented-ASsessmenT (ROAST) framework when providing clinical care for individuals with an acute LAS injury...

CONTEXT: Assessment of sport-related concussion (SRC) has begun to include patient- reported outcome measures (PROMs). However, there is a limited understanding of which health limitations are most meaningful to adolescents following SRC. OBJECTIVE: To explore patient-perceived activity limitations following SRC and throughout recovery to return-to-play (RTP) and mapped according to the International Classification of Functioning, Disability, and Health (ICF) model...

CONTEXT: Limited research exists regarding the perceptions of professionalism of athletic trainers. OBJECTIVE: The purpose of this study was to explore the lived experiences of athletic trainers on their perceptions of professionalism. DESIGN: Qualitative Study. SETTING: Participants were athletic trainers who completed a semi-structured interview protocol via audio-only recording conferencing.
