Greater atrophy and altered specificity of the uniarticular vasti muscles compared to the biarticular rectus femoris has been previously reported.
Reduced knee extensor torque steadiness is a common finding following ACL reconstruction which can contribute to functional limitations, but the relationships between activation patterns of the superficial quadriceps muscles and knee extensor torque output is not well defined.
Collegiate sports that involve cutting, jumping, and pivoting carry a risk of anterior cruciate ligament (ACL) injury.
Following ACL reconstruction, most athletes eventually return to sport (RTS) but may do so with significant limitations in an already short athletic career.
We have developed a protocol to instruct clinicians to obtain detailed and specific information from observational gait analysis to correlate with 3D obtained information and determine the magnitude of dysfunction in post-ACLR running mechanics.
The goal of this investigation is to determine how accurate clinician observational gait analysis of slo motion running gait is in regards to identifying the magnitude of gait abnormalities post-ACL reconstruction.Many students coauthor journal publications and present research findings at national and state meetings.Over 480,000 young adults participate in National Collegiate Athletic Association (NCAA) sports annually.The objectives of this ongoing investigation are to: 1) evaluate knee, hip, and ankle joint kinetics and kinematics during running and jumping in elite collegiate athletes throughout recovery post-ACLR; 2) compare and contrast the extent of kinetic and kinematic asymmetries across tasks post-ACLR; 3) compare LE movement biomechanics between post-ACLR athletes and control subjects matched by gender, sport, and position.Elite-level athletes possess a tremendous ability to perform explosive and rapid movements, developing muscular force within a short time frame.The objectives of this project are to: 1) comprehensively define phase specific force-time variables, and determine which variables are significant predictors of jump height in collegiate athletes; 2) evaluate changes in jump performance throughout the collegiate career of individual athletes; 3) determine the influence of anterior cruciate ligament reconstruction on jump performance in collegiate athletes.Abnormal lower extremity (LE) biomechanics post-anterior cruciate ligament reconstruction (ACLR) may increase re-injury risk and reduce sports performance.Additionally, this study will explore the relationship between the recovery of functional performance with sport participation and subsequent LE injury after ACLR.The goal of this study is to objectively define how ACLR can affect sport exposure and subsequent LE injury in elite collegiate athletes.Furthermore, this study will help determine factors related to a successful RTS and assist in guiding rehabilitation efforts to facilitate RTS.Countermovement jump performance is an important indicator of lower extremity explosiveness and can differentiate elite athletes from their novice counterparts.
