The paper uses simulations to show that passive prostheses increase walking effort for both propulsion and stabilization, while active prostheses reduce effort but require full sensory feedback to fully restore metabolic cost.

This study investigates how mediolateral foot placement is controlled after perturbations affecting linear or angular momentum, finding that linear momentum primarily governs foot placement.

This paper uses stochastic optimal control simulations to study how sensorimotor noise affects walking variability and control strategies, finding that effort minimization shapes gait patterns.

This study investigates how walking speed affects the metabolic cost of balance control, finding that faster speeds reduce the energy needed to stabilize walking.

This study evaluates how well simulations of human gait predict movement mechanics and metabolic power under various conditions, finding underestimation in metabolic power and identifying potential model errors.

This tutorial presents methods to assess stabilizing feedback control of human walking using gait analysis, ranging from simple kinematics to inverse dynamics, with open-source code provided.

The paper evaluates accuracy-speed-stability trade-offs in stepping tasks between young and older adults, finding no age differences in trade-off magnitudes but linking lower stability to reduced accuracy in older adults.

This study finds older adults make more errors and show greater balance variability during shoulder checks while cycling, contributing to higher single-sided bike accident risk.

This study shows that similar sensorimotor transformations control balance during standing and walking, using delayed feedback of center of mass kinematics.
