Data Mining


Discriminant Analysis of Surgical Outcomes

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


Movement Abnormalities (top)


Crouch Gait

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

Stiff-Knee Gait

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?

Biarticular Muscles

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?
