Balance prostheses for postural control

IEEE Engineering in Medicine and Biology Magazine, 2003
There 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.

Degradation of postural control with aging

Proceedings of the Institution of Mechanical Engineers, Part H: Journal of Engineering in Medicine, 2015
Aging negatively impacts the ability to maintain postural stability due to degraded control systems. The entropic half-life, a non-linear variable that quantifies the transition of sample entropy with increasing time scales, quantifies the time that elapses before old positional information no longer influences, or is no longer related to, the control ...

Vestibular humanoid postural control

Journal of Physiology-Paris, 2009
Many of our motor activities require stabilization against external disturbances. This especially applies to biped stance since it is inherently unstable. Disturbance compensation is mainly reactive, depending on sensory inputs and real-time sensor fusion. In humans, the vestibular system plays a major role.

Postural control during lifting

Journal of Biomechanics, 2002
Any 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, 1984
Adaptation 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 ...

Vestibular postural control model

Kybernetik, 1972
Current 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

On the cognitive penetrability of posture control

Experimental Aging Research, 1993
Postural 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.

Posture control of casting manipulation

Proceedings 1999 IEEE International Conference on Robotics and Automation (Cat. No.99CH36288C), 2003
We 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, 1992
Postural 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).
