The neuromuscular system used to stabilize upright posture in humans is a nonlinear
dynamical system with time delays. The analysis of this system is important for improving …

Increased time-delay in the neuromuscular system caused by neurological disorders,
concussions, or advancing age is an important factor contributing to balance loss (Chagdes …

Emergence of postural patterns as a function of vision and translation frequency. We
examined the frequency characteristics of human postural coordination and the role of visual …

The purpose of this study was to investigate whether the coordination between center of
mass (COM) and center of pressure (COP) could be a candidate collective variable of a …

Postural stability depends on interactions between the musculoskeletal system and neural
control mechanisms. We present a frontal plane model stabilized by delayed feedback to …

Postural control may be an ideal physiological motor task for elucidating general questions
about the organization, diversity, flexibility, and variability of biological motor behaviors …

Though simple in appearance, postural stabilization is a complex neuromuscular task
requiring coordination among multiple joints. Mechanisms of postural stability and control in …

For most individuals, balancing upright is a simple task that requires little effort. The inherent
difficulties associated with standing balance are not revealed until a pathology or injury …

Human upright posture is inherently unstable. To counter the mechanical effect of a large-
scale perturbation such as a slip, the CNS can make adaptive adjustments in advance to …

The control of upright stance is commonly explained on the basis of the single inverted
pendulum model (ankle strategy) or the double inverted pendulum model (combination of …
