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 ...

Postural control in healthy individuals
Clinical Biomechanics, 2010The aim of rehabilitation is to optimize functional recovery and frequently following injury, the uninjured limb is used as measure to compare with the injured limb. This assumes that symmetry existed prior to the injury. The aim of this study was to examine postural control in a healthy sample to ascertain if differences exist between the functionally

Postural Control in Elderly Subjects
Age and Ageing, 1990The postural stability of 23 subjects aged 85 years or over was studied with a force platform. The sensory function of the lower limbs was disturbed with small vibrators placed on both calf muscles and/or by placing the subjects on a platform covered with foam plastic.

Balance prostheses for postural control
IEEE Engineering in Medicine and Biology Magazine, 2003There is a clear need for a prosthesis that improves postural stability in the balance impaired. Such a device would be used as a temporary aid during recovery from ablative inner-ear surgery and as a permanent prosthesis for those elderly prone to falls.
