Large lateral head movements and postural control

Postural control of three-dimensional prehension movements.

This experiment was carried out to test the hypothesis that three-dimensional upper limb movements could be initiated and controlled in the joint space via a mechanism comparing an estimate of the current postural state of the upper arm with a target value determined by one specific inverse static transform converting the coordinates of the object into a set of arm, forearm, and wrist angles. T...

Eye Movements Affect Postural Control in Young and Older Females

Visual information is used for postural stabilization in humans. However, little is known about how eye movements prevalent in everyday life interact with the postural control system in older individuals. Therefore, the present study assessed the effects of stationary gaze fixations, smooth pursuits, and saccadic eye movements, with combinations of absent, fixed and oscillating large-field visu...

Effects of saccadic eye movements on postural control stabilization

Several structures of the central nervous system share involvement in both ocular and postural control, but the visual mechanisms in postural control are still unclear. There are discrepant evidences on whether saccades would improve or deteriorate stabilization of posture. The purpose of this study was to determine the influence of saccadic eye movements on postural control while standing in d...

[Performing saccadic eye movements modifies postural control organisation].

AIMS OF THE STUDY To assess to which extent performing saccadic eye movements modifies the postural strategies aimed at maintaining balance. MATERIALS AND METHODS Twelve healthy adults were tested on a force platform in several conditions including one in which they were required to stare a visual target and four in which small and larger saccadic eyes movements were performed vertically and ...
