There are contrasting views on the role of vision in modifying postural organization
(information-driven and postural facilitation) and limited direct tests of the underlying …

Humans receive sensory information from the past, requiring the brain to overcome delays to
perform daily motor skills such as standing upright. Because delays vary throughout the …

It is a fundamental question how our brain performs a given motor task in a real-time fashion
with the slow sensorimotor system. Computational theory proposed an influential idea of …

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

For many physical systems the transition from a stationary solution to sustained small
amplitude oscillations corresponds to a Hopf bifurcation. For systems involving impacts …

Human balance with exoskeleton assistance is studied using an inverted pendulum model,
considering time delays in the muscle reflexes and the exoskeleton controller. The model …

Previous research on movement control suggested that humans exploit stability to reduce
vulnerability to internal noise and external perturbations. For interactions with complex …

The aim of this study was to compare the electromyographic (EMG) coherence between the
lower limb and the core muscles when carrying out two postural tasks at different difficulty …

The origin of continual body oscillation during quiet standing is a neural-muscular-skeletal
closed feedback loop system that includes insufficient joint stiffness and a time delay. Thus …

This paper proposes a new intermittent control model during human quiet standing, which is
consisted of postulated “regular intervention” and “imminent intervention”. The regular …
