Asymmetry of Anticipatory Postural Adjustment During Gait Initiation
The purpose of this study was to investigate the asymmetry of anticipatory postural adjustment (APA) during gait initiation and to determine whether the process of choosing the initial swing leg affects APA during gait initiation. The participants initiated gait with the leg indicated by a start tone or initiated gait with the leg spontaneously chosen. The dependent variables of APA were not si...
متن کاملAn EEG/MEG study of anticipatory postural adjustment in a bimanual load-lifting task
Anticipatory postural adjustments (APA) are necessary for counteracting destabilizing forces induced by prime movements. The present study examined APA in a bimanual load-lifting task using simultaneous electroencephalography (EEG) and magnetoencephalography (MEG). A 1-kg weight placed on the left arm was either lifted by an experimenter (imposed condition) or by the subject (voluntary conditio...
متن کاملContributions of trunk muscles to anticipatory postural control in children with and without developmental coordination disorder.
Current evidence suggests that movement quality is impacted by postural adjustments made in advance of planned movement. The trunk inevitably plays a key role in these adjustments, by creating a stable foundation for limb movement. The purpose of this study was to examine anticipatory trunk muscle activity during functional tasks in children with and without developmental coordination disorder ...
متن کاملTwo aspects of feedforward postural control: anticipatory postural adjustments and anticipatory synergy adjustments.
We used the framework of the uncontrolled manifold hypothesis to explore the relations between anticipatory synergy adjustments (ASAs) and anticipatory postural adjustments (APAs) during feedforward control of vertical posture. ASAs represent a drop in the index of a multimuscle-mode synergy stabilizing the coordinate of the center of pressure in preparation to an action. ASAs reflect early cha...
متن کاملAnticipatory postural adjustments in conditions of postural instability.
OBJECTIVES The purpose of this study was to investigate anticipatory postural adjustments (APAs) in standing subjects who performed a standard motor action triggering a standard postural perturbation (releasing a 2.2 kg load from extended arms) in conditions of different stability requirements. METHODS The degree of stability was varied either by balancing on special boards with long and narr...
