Comparison of Scaled vs. Ultrasound Based Musculoskeletal Models on Knee Muscle Moments During Single-Leg Squatting
Pope, John R. (East Carolina University, 2012)Muscles produce force, resulting in moments about a joint, causing movement of the body. Muscle forces are estimated with a Hill-type model incorporating four parameters; optimal fiber length (OFL), tendon slack length, ... -
Influence of Thigh Muscle Forces on Anterior Cruciate Ligament Forces during Single-Leg Landing from Three Different Heights
Bulluck, Jonathan M. (East Carolina University, 2010)Over 200,000 anterior cruciate ligament (ACL) injuries occur every year amounting to billions of dollars being spent on the ACL annually. While the quadriceps muscle produces an anterior shear force on the tibia that ... -
The Interaction of Trunk-Load and Trunk-Position Adaptations on Knee Anterior Shear and Hamstrings Muscle Forces During Landing
Kulas, Anthony S.; Hortobágyi, Tibor; DeVita, Paul, 1955- (East Carolina University, 2010)Context: Because anterior cruciate ligament (ACL) injuries can occur during deceleration maneuvers, biomechanics research has been focused on the lower extremity kinetic chain. Trunk mass and changes in trunk position ... -
Proximal vs. Distal Fascicle Behavior within the Biceps Femoris Long Head at Different Muscle Activation Levels
Bennett, Hunter J. (East Carolina University, 2013)Hamstring strains have been shown to occur more often in the long head of the biceps femoris (BFLH) than the semitendinosus and semimembranosus, with most injuries occurring in the proximal half of the BFLH. Muscle modeling ...
