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.

The effect of gravity on hand spatio-temporal kinematic features during functional movements

This study examines how gravity affects hand movement kinematics during functional tasks, finding significant differences in movement planning, smoothness, efficiency, and accuracy when movements are against or with gravity.

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.
