The time course of the center of pressure (CoP) during human quiet standing, corresponding
to body sway, is a stochastic process, influenced by a variety of features of the underlying …

Postural sway during quiet standing reflects the interplay between destabilizing forces acting
on the body and actions by the postural control system to prevent a loss of balance. Hence …

This study shows that center-of-pressure (COP) traces that closely resemble physiologically
measured COP functions can be produced by an appropriate selection of model parameters …

Recent studies on postural control have shown that the variability of body sway during quiet
standing may provide valuable information to characterize changes in postural control due …

Maintenance of human upright stance requires the acquisition and integration of sensory
inputs. Conventional measures of sway have had success in identifying age-and some …

This study was done to examine age-stage (preschool children, young adults, and elderly
people) differences in the center-of-pressure sway using body-sway factors (unit-time sway …

The analysis of postural control has a long history. Traditionally, the amount of body sway is
solely used as an index of postural stability. Although this leads to some extent to an …

Postural sway during quiet stance is usually assumed to be a stationary stochastic process.
We tested this assumption by investigating the time invariance of the average value and …

To examine the age-related deterioration in postural control, we investigated the association
between postural sway during quiet standing and either amplitude of physiological tremor or …

Postural control is often quantified by recording the trajectory of the center of pressure (COP)—
also called stabilogram—during human quiet standing. This quantification has many …
