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, ... -
The Effect of Eccentric Hamstring Strength Training on Muscle Function
Seymore, Kayla D. (East Carolina University, 2015)The high prevalence of hamstring strain injury in sports, coupled with detrimental performance and financial effects of hamstring injuries, stress the necessity to implement an intervention capable of minimizing hamstring ... -
The Effect of Injury Prevention Training Programs on Anterior Cruciate Ligament Injuries in Team Sport Athletes
Bogardus, Rima L. (East Carolina University, 2013)Objective: We sought to conduct a meta-analysis to determine whether neuromuscular training programs are effective at reducing anterior cruciate ligament (ACL) injuries. A secondary purpose was to identify and describe ... -
Effect of previous hamstring strain on Anterior Cruciate Ligament (ACL) forces
Geronimo, Alex (East Carolina University, 2016-08-18)Introduction: Anterior Cruciate Ligament (ACL) injuries are very common in the athletic population. While the hamstring muscles help protect the ACL, hamstring strain injuries (HSI) are also common in sports. After HSI, ... -
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 ... -
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 ... -
Semitendinosus Tendon Predictors for Successful Outcomes Post-ACL Reconstruction
Amat Fernandez, Clara (East Carolina University, 2018-05-02)The autologous semitendinosus (ST) tendon is currently the most common type of graft used for Anterior Cruciate Ligament (ACL) reconstructions. Even though most reconstructions enable patients to return to physical activity ... -
The Relationship Between the Hamstrings to Quadriceps Strength Ratio and Anterior Cruciate Ligament Forces
Patterson, Jeffrey M. (East Carolina University, 2016-07-11)Injury to the anterior cruciate ligament (ACL) is one of the most common knee injuries in sports and is associated with other serious health concerns like osteoarthritis (OA). Forces developed by the hamstrings and quadriceps ...
