Postural control in Parkinson's disease [PDF]
Brazilian Journal of Otorhinolaryngology, 2014 Postural instability is one of the most disabling features of Parkinson's disease.To evaluate postural balance in Parkinson's disease.Thirty patients with Parkinson's disease were compared with controls using Tetrax™ interactive balance system posturography.For different positions, patients with Parkinson's disease showed a significantly higher weight ...

Postural control in the elephant
Journal of Experimental Biology, 2021 ABSTRACT As the largest extant legged animals, elephants arguably face the most extreme challenge for stable standing. In this study, we investigated the displacement of the centre of pressure of 12 elephants during quiet standing. We found that the average amplitude of the oscillations in the lateral and fore–aft directions was less ...

Frontiers in Neuroscience, 2018 From ancient Greece to nowadays, research on posture control was guided and shaped by many concepts. Equilibrium control is often considered part of postural control. However, two different levels have become increasingly apparent in the postural control system, one level sets a distribution of tonic muscle activity ("posture") and the other is ...

Mobility as the Purpose of Postural Control [PDF]
Frontiers in Computational Neuroscience, 2017 Abstract Counteracting the destabilizing force of gravity is usually considered to be the main purpose of postural control. However, from the consideration of the mechanical requirements for movement, we argue that posture is adjusted in view of providing impetus for movement.

Anticipatory control of head posture [PDF]
Clinical Neurophysiology, 2007 We tested a hypothesis on two patterns of anticipatory postural adjustments (APAs) in neck muscles, reciprocal and co-activation, that may be used in a task-specific way. We also explored possible relation of APAs in leg and trunk muscles to head stabilization.Load perturbations (loading and unloading) were applied to the head, trunk, and head and ...

Postural threat increases sample entropy of postural control
Frontiers in Neurology, 2023 IntroductionPostural threat elicits modifications to standing balance. However, the underlying neural mechanism(s) responsible remain unclear. Shifts in attention focus including directing more attention to balance when threatened may contribute to the balance changes.

Postural control in blind subjects [PDF]
Einstein (São Paulo), 2011 ABSTRACT Objective: To analyze postural control in acquired and congenitally blind adults. Methods: A total of 40 visually impaired adults participated in the research, divided into 2 groups, 20 with acquired blindness and 20 with congenital blindness − 21 males and 19 females, mean age 35.8 ± 10.8.

Hypothetical control of postural sway [PDF]
Journal of The Royal Society Interface, 2020 Abstract Quiet standing exhibits strongly intermittent variability that has inspired at least two interpretations. First, variability can be intermittent through the alternating engagement and disengagement of complementary control processes at distinct scales.

POSTURAL CONTROL IN THE ELDERLY
Nippon Jibiinkoka Gakkai Kaiho, 1992 In order to investigate postural control in the elderly, a stabilometric investigation including fast Fourier Transform (FFT) analysis was conducted in three different age groups. The oldest group was composed of 16 subjects who ranged in age from 75 to 86 years: another group consisted of eight 65 to 74 year olds; the control group was composed of 21 ...

Cortical control of postural responses [PDF]
Journal of Neural Transmission, 2007 This article reviews the evidence for cortical involvement in shaping postural responses evoked by external postural perturbations. Although responses to postural perturbations occur more quickly than the fastest voluntary movements, they have longer latencies than spinal stretch reflexes, suggesting greater potential for modification by the cortex ...
