The Relationship Between Vertical Ground Reaction Force, Loading Rate, and Sound Characteristics During a Single-Leg Landing

Caroline Lisee, Tom Birchmeier, Arthur Yan, Brent Geers, Kaitlin O’Hagan, Callum Davis, and Christopher Kuenze

the relationship between audio characteristics and vGRFs remains consistent across other tasks that have been implicated in ACL injury risk such as single-leg landing. 17 , 18 Single-leg landings have been identified as a common mechanism of ACL injury, 19 but many prospective injury prevention

Variables Associated With Knee Valgus in Male Professional Soccer Players During a Single-Leg Vertical Landing Task

Matheus Vianna, Leonardo Metsavaht, Eliane Guadagnin, Carlos Eduardo Franciozi, Marcus Luzo, Marcio Tannure, and Gustavo Leporace

programs to suit the unique needs of this population. Therefore, this study aimed to investigate the correlation between knee valgus and lateral trunk inclination, hip adduction, and internal rotation angles during a continuous single-leg vertical landing task in professional male soccer athletes as well

The Influence of Hip Structure on Functional Valgus Collapse During a Single-Leg Forward Landing in Females

Jennifer A. Hogg, Randy J. Schmitz, and Sandra J. Shultz

and internal rotation, and associated external joint moments, particularly knee abduction moment and knee internal rotation moment. 5 – 7 Evidence suggests that the hip and knee move as a unit, particularly in single-leg tasks. Greater movement toward hip internal rotation and adduction is reported

Single-Leg Squat Test in the Clinical Setting Does Not Discriminate Patients With Femoroacetabular Impingement Syndrome From Asymptomatic Individuals

Letícia Almeida de Oliveira, Viviane Bortoluzzi Frasson, Anna Torresan, Marco Aurélio Vaz, and Bruno Manfredini Baroni

performance. 9 , 10 Using 3-dimensional (3D) kinematic analysis, Malloy et al 11 demonstrated that a single-leg squat (SLS) task exaggerated movement–pattern differences between people with FAIS and those without hip pain when compared with a double-leg squat task, suggesting that clinicians might consider

Measurement Properties of Clinically Accessible Movement Assessment Tools for Analyzing Single-Leg Squats and Step-Downs: A Systematic Review

Erin M. Lally, Hayley Ericksen, and Jennifer Earl-Boehm

LE movement assessments vary, but 2 common tasks observed are the single-leg squat (SLS) 8 , 10 , 15 and step-down (SD). 11 , 16 Physical outcome measures (PhOM) should have established reliability. Reliability describes the consistency of a measurement under different conditions. 17 Three types of

Optimizing Whole-Body Kinematics During Single-Leg Jump Landing to Reduce Peak Abduction/Adduction and Internal Rotation Knee Moments: Implications for Anterior Cruciate Ligament Injury Risk

Dhruv Gupta, Jeffrey A. Reinbolt, and Cyril J. Donnelly

/adduction and internal rotation knee moments that elevates the ACL load and injury risk more than either in isolation. 16 Therein, it should be the focus of injury-prevention frameworks to reduce both abduction/adduction and internal rotation moments during the weight-acceptance phase of single-leg landing and

Female Athletes With Varying Levels of Vertical Stiffness Display Kinematic and Kinetic Differences During Single-Leg Hopping

Justin P. Waxman, Kevin R. Ford, Anh-Dung Nguyen, and Jeffrey B. Taylor

kinetic characteristics between adolescent female athletes with varying levels of vertical stiffness, as evaluated via a stationary single-leg hopping task. We hypothesized that athletes with lower stiffness would display lesser peak vertical ground reaction forces, greater peak joint angles and joint
