Tyrannosaurus Rex

Optimization of the limb at midstance was used to determine which pose maximized center of mass acceleration.

Muscle-Actuated Human (top)

A series of optimizations were used to determine whether crouched postures provided unrecognized benefits by increasing the capacity of muscles to generate ground reaction forces.

Simulated rectus femoris transfer surgeries were used to determine mechanisms of improved knee flexion and the importance of preswing muscle activity.

Torque-Actuated Human (top)

Optimization calibrated patient-specific models to predetermine the effect of post-treatment outcomes.

Monte Carlo analyses were used to determine whether patient-specific joint and inertial parameters are necessary for accurate joint torque calculations.

Optimization was used to evaluate whether patient-specific models can be calibrated accurately from noisy kinematic data.

Support-Surface Translation(top)

Support-surface translation to evaluate postural response and CoM displacement.
