Postural control: Visual and cognitive manipulations
… the utilization of sensory information for postural control. Past research establishes the possibility that cognitive tasks requiring visual perception may affect the processing of visual information for postural control. The purpose of this study was to investigate the effects of varying …

Adaptation and learning in postural control
… life. Failure to attain and maintain the control of upright posture can have catastrophic consequences. Postural competence needs to be recovered in a multitude of illness, in developmental disorders as well as to age related decreasing function. To meet this end, health professionals …

Dynamic strategies of human postural control
… two goals pursued in this study were to identify controllable dynamic characteristics of human posture and to approach the description of these characteristics by means of computer graphics. The notion that virtual time-to-contact, which specifies the spatio-temporal proximity of the pressure …

Dynamic Postural Control In Individuals With Multiple Concussions
… walk, has effectively identified impairments in postural control in a wide range of neurologically impaired populations (e.g., post-stroke, Parkinson's, aging). Therefore, the purpose of this study was to identify impairments in postural motor control in individuals with a history of 3 or more …

Concussions in wheelchair users: quantifying seated postural control
… detect concussions in this population, a seated postural control test was developed. It was the aim of this investigation to determine if this test was valid, reliable and sensitive to concussions in wheelchair athletes. . Methods Participants Wheelchair athletes who were part of a collegiate …

Effects of Isolated Core Stability Training on Standing Static Postural Control, Recovery of Standing Postural Control and Kicking Velocity in Soccer Athletes
… and LE’s is predominantly accomplished via quick postural responses to internal and external forces. These pre-programed postural responses are integrated within the neuromuscular system. It is theorized that poor core stability is a result of a failure in the neuromuscular system to support the …

Visual-Oculomotor and Head Movement Strategies in Postural Control
Postural control requires the integration of visual, vestibular, and proprioceptive information to maintain stability. The gold standard for inferring postural control relies on lab-based tools, such as force plates and full-body motion capture to track center of mass (COM) and center of pressure …

NEW PERSPECTIVES ON POSTURAL CONTROL IN CHILDREN AND ADULTS
… posture. The research activity RA-1 involved the postural analysis of children with neurological or neuromuscular diseases with the aim of differentiating the pathologies under study; the others (RA-2 and RA-3) focused on gait initiation (GI). Specifically, I started a study (RA-2) to assess the …

Postural control and adaptation to threats to balance stability
Postural control is the ability to maintain equilibrium and orientation in a gravitational environment. It is dependent on feedback and feedforward mechanisms that generate appropriate corrective movement based on body-sway motion detected primarily by visual, vestibular, and proprioceptive sensory …

Quantification of the human postural control system to perturbations
… standing posture is inherently unstable. The postural control system (PCS), which maintains standing posture, is composed of the sensory, musculoskeletal, and central nervous systems. Together these systems integrate sensory afferents and generate appropriate motor efferents to adjust posture. …

EFFECTS OF VESTIBULAR TRAINING ON POSTURAL CONTROL OF HEALTHY ADULTS
Background: Postural stability is maintained by the central integration of the multisensory inputs to produce motor outputs. When visual and somatosensory input is available and reliable, this reduces the postural control system’s reliance on the vestibular system. Despite this, vestibular loss can …

Assessing variability of postural control over time using nonlinear dynamics
… of this study is to assess the variability of postural sway over time using nonlinear dynamics of ApEn and SampEn. A total of twenty-one participants (age: 78.6 ± 5.7) were recruited and completed thirty days of daily balance assessment, along with a baseline and follow-up assessment. At …

Longitudinal Locomotor and Postural Control Following Mild Traumatic Brain Injury
… non-straight maneuvers or on indicators of motor control variability or complexity. To expand the knowledge of post-concussion locomotor and postural changes, this investigation examined the recovery of recently concussed athletes longitudinally, over the course of one year, in three domains: 1) …

ALTERATIONS IN POSTURAL CONTROL FOLLOWING AN ACUTE BOUT OF SOCCER HEADING
… acute bout of soccer heading adversely altered postural control and pronounced self-reported symptoms of cerebral concussion. Sixteen collegiate soccer players were randomly assigned to one of two groups: control (CG) or experimental (EG). Participants either simulated or performed 10 headers in …

Impairment in Dynamic Postural Control Following an Acute Lateral Ankle Sprain
… 25,000 per day. Current research assesses postural control deficits following lateral ankle sprains; however most studies use static stances instead of dynamic stances. Most of the current research compares injured limb to non-injured limb, however bilateral impairments have been found to …
