Can force-plate measurement be trusted for balance diagnostics? Frequency-domain force-plate performance assessment for quiet-standing studies

This study assesses the performance of a portable force plate in measuring shear forces during quiet standing, finding it only marginally meets precision requirements for balance diagnostics.

Foot-Ground Force Quantifies Impaired Balance Control Mechanisms Post-Stroke

This study uses computational modeling of foot-ground force data to identify distinct balance control strategies in post-stroke individuals compared to unimpaired adults.

Muscle Stiffness, Not Force, Limits Human Force Production

This study investigates how muscle stiffness, not force, limits human force production by testing the effects of wrist stabilization and limb configuration on maximum pushing force.

Tuning of Task-Relevant Stiffness in Multiple Directions

This study shows humans predictively adjust arm stiffness before movement to optimize task success, even at the cost of energy efficiency.

On Human Motor Coordination: The Synergy Expansion Hypothesis

This paper proposes the expansion hypothesis to explain how humans develop, learn, and use motor synergies, addressing Bernstein's degrees of freedom problem through mechanical, developmental, and behavioral perspectives.

Behavioral Consequences of Velocity Commands: Brownian Processes in Human Motor Tasks

This study investigates the behavioral consequences of velocity commands in human motor tasks, finding that noise in velocity commands leads to Brownian motion patterns in position.
