Nonstationarities of postural sway

IEEE Engineering in Medicine and Biology Magazine, 2003
Time-frequency analysis of visually induced postural sway has uncovered potentially important time-dependent spectral changes in sway, particularly over intervals shorter than most trial lengths (tens of seconds). Specifically, our studies of center of pressure (COP) in response to sinusoidal (0.25 Hz) moving scene perturbations demonstrate that there ...

Hyperventilation effect on postural sway

Archives of Physical Medicine and Rehabilitation, 1997
To examine the effect of voluntary hyperventilation (HV) on postural sway.Crossover controlled, experimental study.Human movement and balance clinical research unit.Four different groups of normal subjects (n = 6, 6, 7, and 9) and patients with bilateral absence of vestibular function (n = 9).Partial carbon dioxide pressure (tc-PCO2) was measured ...

Aging and Postural Sway in Women

Journal of Gerontology, 1975
The effects of aging on postural sway in upright and forward lean stance were investigated. Postural sway was measured on a center of gravity apparatus using two age groups of female subjects 20 to 30 years old and 70 to 80 years old. The older adults demonstrated significantly larger sway areas than the young adults in both stance positions.

Nonstationary properties of postural sway

Journal of Biomechanics, 1993
Postural sway during quite stance is usually assumed to be a stationary stochastic process. We tested this assumption by investigating the time invariance of the average value and variance of the postural sway of three subjects. The sway was measured with a force plate under three conditions: subject standing on two feet with eyes open; subject ...
