Postural threat influences conscious perception of postural sway
Neuroscience Letters, 2016This study examined how changes in threat influenced conscious perceptions of postural sway. Young healthy adults stood on a forceplate mounted to a hydraulic lift placed at two heights (0.8m and 3.2m). At each height, subjects stood quietly with eyes open and eyes closed for 60s.

Body Sway Stabilization in Human Posture
Acta Oto-Laryngologica, 1990Electromyographic (emg) responses and joint movements of the leg were analysed in subjects standing with eyes closed on a sinusoidally moving treadmill (0.16 Hz or 0.33 Hz, amplitude 33 cm). Activity in antagonistic leg muscles was reciprocally modulated, with a predominant gastrocnemius activation during deceleration of forward movement and tibialis ...

A wearable device to assess postural sway
2019 IEEE 23rd International Symposium on Consumer Technologies (ISCT), 2019The maintenance of balance in upright stance is traditionally evaluated using heavy and expensive force platforms. The aim of this work is to prove the usefulness of a low-cost wearable sensor (an actigraph) to assess postural sway. We compared the performance of the device to a gold standard force platform. We analyzed measurements of postural sway in

Effect of Exercise on Postural Sway in the Elderly
Gerontology, 2009Fifty female subjects, aged 72–92 (mean 82) years, were enrolled in a 12-week (36 classes) exercise program aimed at increasing postural stability. Subjects were residents of sheltered apartments, rest homes or nursing homes, well enough and mobile enough to participate in the classes.

Maturation Of Postural Sway In Young Children
Developmental Medicine & Child Neurology, 1987SUMMARYThe postural sway of 76 healthy young children aged from two to 14 years was investigated to identify age‐related changes in the extent of sway, the effects of eye‐closure, and the spectral composition of sway. Postural sway was measured from the excursions of the centre of pressure of ground reaction forces, and was analysed for both time and ...

A Biofeedback Study of Postural Sway
Psychiatry and Clinical Neurosciences, 1976An experiment was performed to control postural sway under auditory and visual feedback signals using a new apparatus. The subjects of 52 healthy high school girls were divided into 13 small groups. Each small group had four subjects who were assigned to one of the following four groups; 1) visual feedback group, 2) auditory feedback group, 3) auditory

Visual Fixation and Postural Sway in Children
Journal of Motor Behavior, 1989Adults are able to use a visual target to reduce quiet-standing postural sway (Lee & Lishman, 1975). The present study was designed to determine whether children, under varying postural conditions, are also able to use a visual target to reduce postural sway.

Respiratory components of human postural sway
Neuroscience Letters, 1981The effects of respiration on postural sway in normal human subjects was studied using averaging and spectral techniques. During voluntarily paced respiration a substantial proportion of sway was found to result from respiratory activity. The magnitude of the respiratory contribution to sway was approximately constant over the normal range of ...

Postural sway and diabetic peripheral neuropathy
Diabetes Research and Clinical Practice, 2001The focus of this paper is to evaluate the relationship between postural sway assessed by a gravicorder and peripheral neuropathy in patients with type 2 diabetes. Posturography (GRAVICHART), electrophysiological tests, and power spectrum analysis of heart rate fluctuations were performed in the following age-matched subjects: 123 type 2 diabetic ...

The spectral characteristics of postural sway behaviour
European Journal of Applied Physiology and Occupational Physiology, 1982To determine whether recognisable profiles of sway behaviour are characteristically found among normal subjects the energy content of a contiguous series of bandwidths were computed from power density spectra of the sway behaviour of 29 young men and 29 young women.
