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.

Postural control and adaptation are influenced by preceding postural challenges
Experimental Brain Research, 2010We investigated the possible consequences of two consecutive postural tasks on adaptation. Four groups (total number of 46 healthy subjects) were perturbed on two consecutive days with vibration stimulus to tibialis anterior or posterior calf muscles, or both in different orders. Postural movements were recorded with a force platform.

Postural control during lifting
Journal of Biomechanics, 2002Any voluntary motion of the body causes an internal perturbation of balance. Load transfer during manual material handling may increase these perturbations. This study investigates effects of stance condition on postural control during lifting. Nineteen healthy subjects repeatedly lifted and lowered a load between a desk and a shelf.

Adaptation of postural control to weightlessness
Experimental Brain Research, 1984Adaptation of motor control to weightlessness was studied during a 7-day spaceflight. The maintenance of control of upright posture was examined during a voluntary raising movement of the arm and during the voluntary raising on tiptoe. In order to evaluate the contribution of visual cues, three types of visual situations were examined: normal vision ...

On the cognitive penetrability of posture control
Experimental Aging Research, 1993Postural sway increases with age. The decreased stability associated with postural sway often has been related to the reduced peripheral sensibility in the visual, vestibular, and proprioceptive systems. We examined whether the micropostural adjustments necessary for maintaining balance also require some cognitive processing.

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.

Modeling postural control in the lamprey
Biological Cybernetics, 2001A phenomenological model of the mechanism of stabilization of the body orientation during locomotion (dorsal side up) in the lamprey is presented. The mathematical modeling is based on experimental results obtained during investigations of postural control in lampreys using a combined in vivo and robotics approach.

Hand Postures for Sonification Control
2002Sonification is a rather new technique in human-computer interaction which addresses auditory perception. In contrast to speech interfaces, sonification uses non-verbal sounds to present information. The most common sonification technique is parameter mapping where for each data point a sonic event is generated whose acoustic attributes are determined ...
