Postural control during kneeling
Experimental Brain Research, 2008Postural control was studied when the subject was kneeling with erect trunk in a quiet posture and compared to that obtained during quiet standing. The analysis was based on the center of pressure motion in the sagittal plane (CPx), both in the time and in the frequency domains.

The effect of trunk muscle fatigue on postural control of upright stance: A systematic review.
Gait & Posture, 2019BACKGROUND Fatigability and postural control deficits are both serious concerns in a variety of chronic musculoskeletal conditions. Research has shown that muscle fatigue may adversely affect postural control.

Vestibular humanoid postural control
Journal of Physiology-Paris, 2009Many of our motor activities require stabilization against external disturbances. This especially applies to biped stance since it is inherently unstable. Disturbance compensation is mainly reactive, depending on sensory inputs and real-time sensor fusion. In humans, the vestibular system plays a major role.

Current Opinion in Neurobiology, 1994
The postural control system has two main functions: first, to build up posture against gravity and ensure that balance is maintained; and second, to fix the orientation and position of the segments that serve as a reference frame for perception and action with respect to the external world.

Vestibulospinal Control of Posture
2002To 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.

Nervous mechanisms controlling body posture
Physiology & Behavior, 2007This paper briefly summarizes the studies of nervous mechanisms controlling the body posture, which were performed in the Department of Neuroscience of the Karolinska Institute during the last decade. Postural mechanisms were investigated in "animal models" of different complexity--the mollusk, lamprey, rabbit, and cat.

Vestibular postural control model
Kybernetik, 1972Current models for physiological components and a posture control experiment conducted with three normal subjects form the basis for a model which seeks to describe quantitatively the control of body sway when only vestibular motion cues are used. Emphasis is placed on delineating the relative functional roles of the linear and the angular acceleration

BIOMECHANICS OF POSTURAL CONTROL
Exercise and Sport Sciences Reviews, 1982There 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.

Brain and muscle activation patterns during postural control affect static postural control
Gait & Posture, 2022Previous studies have reported existence of coordinated brain and muscle activity patterns that affect postural control. However, differences in these activity patterns that affect postural control are still unclear. The purpose of this study was to clarify brain and muscle activity pattern affecting postural control.Does the difference in brain and ...

Posture control after prolonged exercise
European Journal of Applied Physiology, 1997The perturbations of equilibrium after prolonged exercise were investigated by dynamic posturography on nine well-trained subjects (four athletes and five triathletes). A sensory organization test, where the platform and visual surround were either stable or referenced to the subject's sway with eyes open or closed, was performed before and after a 25 ...
