Data Mining

Is it possible to predict whether or not a patient's knee motion will improve following rectus femoris transfer surgery?

Movement Abnormalities (top)

Does walking in a crouched posture have unrecognized benefits? Does a crouched posture increase the capacity of muscles to generate ground reaction forces?

What are the mechanisms of improved knee flexion after rectus femoris transfer surgery? What is the importance of preswing rectus femoris activity as a biomechanical factor contributing to diminished knee flexion?

What is the influence of biarticular muscles on posture control? Does surgical transfer of the rectus femoris to the insertion of the sartorius compromise postural stability?

Predicting Outcomes (top)

Can a patient-specific model using modified leg geometry to simulate high tibial osteotomy surgery predict knee adduction torque outcomes?

Can a patient-specific model using different foot path trajectories predict knee adduction torque changes?

Emergent Behaviors (top)

Are there novel running motions that reduce knee adduction torque in athletes performing a sidestepping manuever?

Are there novel walking motions that reduce the knee adduction torque in patients with knee osteoarthritis?

What are the individual muscle force contributions to single-leg jump landing? How do they support the knee and reduce ACL injury risk?

Patient-Specific Modeling (top)

Are patient-specific joint and inertial properties necessary for accurate inverse dynamics analyses of gait?

Can estimated model parameters by improved through optimization?

Controller Development (top)

How feedback control can be utilized to study musculoskeletal conditions and generate new patient-specific rehabilitation strategies.
