Y-balance test performance and BMI are associated with ankle sprain injury in collegiate male athletes.

Objectives: To determine if static balance, dynamic balance, ankle range of motion, body mass index (BMI), or history of an ankle sprain were associated with ankle sprain injuries within male and female collegiate athletes.

Design: Prospective cohort.

Methods: Three hundred and eighty-four male (age=19.

Y-Balance Test Performance Following a Competitive Field Hockey Season: A Pretest-Posttest Study.

Context: The Y-Balance Test (YBT) is a dynamic balance assessment used as a preseason musculoskeletal screen to determine injury risk. While the YBT has demonstrated excellent test-retest reliability, it is unknown if YBT performance changes following participation in a competitive athletic season.

Objective: Determine if a competitive athletic season affects YBT performance in field hockey players.

Reliability and responsiveness of gait initiation profiles in those with chronic ankle instability.

Individuals with chronic ankle instability (CAI) have demonstrated deviations in gait initiation (GI) compared to healthy individuals. However, the intersession reliability of GI measures remains unknown in this population. The objective of this study was to determine the reliability and responsiveness of GI measures between two testing days in those with CAI.

Various methods for assessing static lower extremity alignment: implications for prospective risk-factor screenings.

Context: Accurate, efficient, and reliable measurement methods are essential to prospectively identify risk factors for knee injuries in large cohorts.

Objective: To determine tester reliability using digital photographs for the measurement of static lower extremity alignment (LEA) and whether values quantified with an electromagnetic motion-tracking system are in agreement with those quantified with clinical methods and digital photographs.

Design: Descriptive laboratory study.
