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 ...

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 ...

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 the Older Adult
Clinics in Geriatric Medicine, 1996Age-related changes in the neural, sensory, and musculoskeletal systems can lead to balance impairments that have a tremendous impact on the ability to move about safely. The many complex substrates of the posture control system subserve a common functional goal: regulation of the relationship between the center of mass and the base of support ...

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

Posture control of casting manipulation
Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003We develop a casting manipulator which includes a flexible string in the link mechanism to enlarge the work space of the manipulator. During casting manipulation the gripper is thrown to the target by releasing the string at a suitable time after generating enough motion by swinging.

Postural control in children with autism
Journal of Autism and Developmental Disorders, 1992Postural control was evaluated in samples of autistic, normal, and mentally retarded children in this pilot study using a recently developed, computerized posturographic procedure. A battery of postural positions was administered including postures involving some degree of "stress" (e.g., occluded vision or standing on pads).

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.

Comparative neurobiology of postural control
Current Opinion in Neurobiology, 2002In recent years, studies of nervous mechanisms for the control of body posture have been performed on animal models of different complexity - cat, rabbit, lamprey and the mollusc Clione. These studies have greatly expanded our knowledge of how the control system operates, how the system can change the stabilized body orientation and how the postural ...

Normal posture depends upon the integrated activity of many different regions of the brain. Certain postures are assumed in repose; others are exhibited before any coordinated movement is carried out. The essential elements for most postural activities are present in the spinal cord.
