BIOMECHANICS OF POSTURAL CONTROL
Exercise and Sport Sciences Reviews, 1982There are no separate mechanisms for posture and movement. Postural reactions are fundamental in neural organization, and movement in its most elementary form is seen as a modification of posture.D.

Current Opinion in Neurobiology, 1994
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 in Lyric Singers
Journal of Voice, 2022Singers are unique musicians because they use their whole body as a musical instrument. Posture and proprioception are key components for a robust and healthy voice.This study aimed to analyze the postural control of lyric singers in different sensorimotor conditions.Seventeen lyric singers were compared to a control group of 12 participants in static ...

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 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

Balance prostheses for postural control
IEEE Engineering in Medicine and Biology Magazine, 2003There 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, 2015Aging 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, 2009Many 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, 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.
