Recent advances in integrative studies of locomotion have revealed several general
principles. Energy storage and exchange mechanisms discovered in walking and running …

Current understanding of how muscles coordinate walking in humans is derived from
analyses of body motion, ground reaction force and EMG measurements. This is Part I of a …

Walking and running have fundamentally different biomechanics, which makes develo**
devices that assist both gaits challenging. We show that a portable exosuit that assists hip …

During running, the lower limbs musculo-tendinous system behaves like a spring-mass
system. From an external mechanical point of view, the complexity of the running motion …

When humans hop in place or run forward, they adjust leg stiffness to accommodate
changes in stride frequency or surface stiffness. The goal of the present study was to …

Walking on uneven terrain is more energetically costly than walking on smooth ground, but
the biomechanical factors that contribute to this increase are unknown. To identify possible …

Background: Gait disorders, a highly prevalent condition in older adults, are associated with
several adverse health consequences. Gait analysis allows qualitative and quantitative …

▪ Abstract Recent interest in using modeling and simulation to study movement is driven by
the belief that this approach can provide insight into how the nervous system and muscles …

Principles of muscle coordination in gait have been based largely on analyses of body
motion, ground reaction force and EMG measurements. However, data from dynamical …

Walking is often modeled as an inverted pendulum system in which the center of mass
vaults over the rigid stance limb. Running is modeled as a simple spring-mass system in …
