Mechanical Equilibrium of Step Transition Governs Vertical Ground Reaction Force Morphology in Human Walking

This study investigates how mechanical factors during walking shape vertical ground reaction force (vGRF) profiles, finding that asymmetry in step-transition work influences vGRF morphology and introducing a new metric to assess gait efficiency.

A Modified Approach to Define Walking Center of Mass Mechanical Energy Recovery: Human Walking Involves Energy Loss Throughout Stance

This paper introduces a modified definition of center-of-mass energy recovery in human walking, showing it decreases with speed and is influenced by dissipation and muscle work.
