Correlation between the knee adduction torque and medial contact force for a variety of gait patterns
The external knee adduction torque has been proposed as a surrogate measure for medial compartment load during gait. However, a direct link between these two quantities has not been demonstratedExpand

A state-space analysis of mechanical energy generation, absorption, and transfer during pedaling.
Seated ergometer pedaling is a motor task ideal for studying basic mechanisms of human bipedal coordination because, in contrast to standing and walking, fewer degrees of freedom are being controlledExpand
