Postural control in the elephant

Journal of Experimental Biology, 2021
ABSTRACT As the largest extant legged animals, elephants arguably face the most extreme challenge for stable standing. In this study, we investigated the displacement of the centre of pressure of 12 elephants during quiet standing. We found that the average amplitude of the oscillations in the lateral and fore–aft directions was less ...

Postural Control and Age

Acta Oto-Laryngologica, 1993
We quantified the effect of vision, pressoreceptor function and proprioception on the postural stability at different ages. Altogether 212 healthy volunteers (ages from 6 to 90 years) were examined by using a computerised force platform. The sway velocity (SV) was measured with eyes open and eyes closed during quiet stance on a bare platform and a foam

The control of movement and posture

Brain Research, 1973
Abstract This report attempts to summarize material discussed at a recent conference on the control of movement and posture, held under the auspices of the Fogarty International Center at the National Institutes of Health, Bethesda, Md., on March 27th and 28th, 1972.

Postural control is scaled to level of postural threat

Gait & Posture, 2000
This study investigated control of posture when standing at different surface heights above ground level. Alterations in surface height were used to modify threat to postural control. Sixty-two healthy adults (mean+/-S.D.=20.3+/-1.3 years) stood quietly on a force plate 40 cm (LOW threat), 100 cm (MEDIUM threat) or 160 cm (HIGH threat) above ground ...

Visual and postural control of an arbitrary posture: The handstand

Journal of Sports Sciences, 2007
The aim of this study was to increase our understanding of postural regulation by analysing an arbitrary posture - the handstand. We assessed the relative influence of peripheral vision and central visual anchoring on the postural balance of gymnasts in the inverted-stand posture.

Internal models in the control of posture

Neural Networks, 1999
The aim of the paper is to investigate the application of control schemes based on "internal models" to the stabilization of the standing posture. The computational complexities of the control problems are analyzed, showing that muscle stiffness alone is insufficient to carry out the task.

Postural Control in Lyric Singers

Journal of Voice, 2022
Singers are unique musicians because they use their whole body as a musical instrument. Posture and proprioception are key components for a robust and healthy voice.This study aimed to analyze the postural control of lyric singers in different sensorimotor conditions.Seventeen lyric singers were compared to a control group of 12 participants in static ...

Vestibulospinal Control of Posture

2002
To better understand the role of the vestibular system in postural coordination, we compared the ability of subjects with complete, bilateral loss of vestibular function and age-matched control subjects to maintain equilibrium and postural orientation during sinusoidal displacements of the support surface at a variety of frequencies.

BIOMECHANICS OF POSTURAL CONTROL

Exercise and Sport Sciences Reviews, 1982
There are no separate mechanisms for posture and movement. Postural reactions are fundamental in neural organization, and movement in its most elementary form is seen as a modification of posture.D.
