In the search of a reliable postural stability index, two sway time series: the center-of-mass
(COM) and the center-of-foot pressure (COP) were recorded simultaneously in elderly …

Analysis of the postural stability impairments in neurodegenerative diseases is a very
demanding task. Age-related declines in posturographic indices are usually superimposed …

We studied the reliability of different measures of the visual contribution to postural
steadiness by recording the postural sway during standing with eyes open (EO) or eyes …

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 …

Directional characteristics of postural sway and their impact on postural stability control
(PSC) still need to be clarified. To assess the directional characteristics of PSC, center-of …

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 …

Age-related changes in postural control are attributed to visual, vestibular and
proprioceptive dysfunctions, muscle weakness, and reduced availability of neural resources …

Despite the obvious advantages and popularity of static posturography, universal standards
for posturographic tests have not been developed thus far. Most of the center-of-foot …

A total of 800 posturographic measurements–each characterized by four values (sway path,
sway area, anteroposterior sway and lateral sway)–was carried out for this study. Eight …

Aims of the study.–Only a good knowledge of the effects of age on postural stability allows
differentiating between physiological aging and pathologies leading to its impairment. The …
