Star Excursion Balance Test Anterior Asymmetry Is Associated With Injury Status in Division I Collegiate Athletes.

Study Design Retrospective cohort. Background Star Excursion Balance Test (SEBT) performance differs by sport in healthy collegiate athletes, and lower extremity injury rates also vary by sport, sex, and athletic exposure. The relationship between SEBT performance and injury risk has not been evaluated with consideration of these additional variables, which may be necessary to fully describe the relationship between SEBT performance and injury risk.

High School Sport Specialization Patterns of Current Division I Athletes.

Background: Sport specialization is a strategy to acquire superior sport performance in 1 sport but is associated with increased injury risk. Currently, the degree of high school specialization among Division I athletes is unknown.

Hypothesis: College athletes will display increased rates of specialization as they progress through their high school careers.

Star Excursion Balance Test Performance Varies by Sport in Healthy Division I Collegiate Athletes.

Study Design: Cross-sectional.

Objectives: To describe performance and asymmetry on the Star Excursion Balance Test (SEBT) by sex and sport, and to determine if differences exist within a collegiate athlete population.

Background: Performance on the SEBT may differ between sexes and levels of competition, though the results of previous studies have been inconsistent.

Squatting mechanics in people with and without anterior cruciate ligament reconstruction: the influence of graft type.

Background: Single-legged squat mechanics change after anterior cruciate ligament (ACL) reconstruction and rehabilitation, but it is unclear if changes in squat mechanics are graft specific.

Purpose: To investigate graft differences in biomechanics of the knee, hip, and trunk during the single-legged squat in patients with ACL-reconstructed knees, determine if these factors were associated with deficits in knee extension moment, and determine if subjective knee function and squat biomechanics are related.

Study Design: Cross-sectional study; Level of evidence, 3.

Range of motion, postural alignment, and LESS score differences of those with and without excessive medial knee displacement.

Objective: To determine range of motion (ROM), postural alignment, and dynamic motion differences between those with and without medial knee displacement (MKD) during the overhead squat (OHS). We hypothesized those with MKD would have restricted ROM, differing postural alignment, and poorer quality dynamic motion than those without MKD.

Design: Observational.

Jump-landing mechanics after anterior cruciate ligament reconstruction: a landing error scoring system study.

Context: The Landing Error Scoring System (LESS) is a clinical evaluation of jump-landing mechanics and may provide useful information in assisting with return-to-sport decisions in patients after anterior cruciate ligament reconstruction (ACLR). However, it is currently unknown how patients with ACLR perform on the LESS compared with healthy controls.

Objective: To determine if the total LESS score differed between individuals with ACLR and healthy controls and to determine the types of errors that differ between groups.
