The output of the human postural control system is highly irregular, even under quiet-standing conditions. To describe the observed dynamics of human posture control, we propose a simple, analytical stochastic model, consisting of a pinned polymer. For such a system, there exists a uctuation-dissipation theorem (FDT), which provides a linear relationship between the correlations of the system a...

Humans display anticipatory motor responses to minimize the adverse effects of predictable perturbations. A widely accepted explanation for this behaviour relies on the notion of an inverse model that, learning from motor errors, anticipates corrective responses. Here, we propose and validate the alternative hypothesis that anticipatory control can be realized through a cascade of purely sensor...

Here we review a role of a basal ganglia-brainstem (BG-BS) system throughout the mesopontine tegmentum in the control of various types of behavioral expression. First the basal ganglia-brainstem system may contribute to an automatic control of movements, such as rhythmic limb movements and adjustment of postural muscle tone during locomotion, which occurs in conjunction with voluntary control p...

BACKGROUND AND PURPOSE In a randomized study of hemiparetic stroke patients with a median age of 75 years, functional recovery was significantly better in those who received additional sensory stimulation (n = 38), including electrostimulation, than in control patients (n = 40) given the same physiotherapy and occupational therapy; group differences for balance, mobility, and activities of dail...

Pronation distortion syndrome is one of the most common abnormalities in the body that causes distortions in the structures of the skeletal structures of the lower extremities and increases postural sways. The purpose of this study was to determine the effect of 12-week corrective exercises on postural sways in male students with pronation distortion syndrome. In this semi experimental research...

s / Gait & Posture 46 (2016) 208–220 213 COP registrations are often complemented with EMG measures and/or measures of cortical activity, allowing a better understanding of how intermuscular coordination of balance is regulated [17–21]. Alsodirect and indirectmeasures of the attentional investment in postural control are often used, such as stimulus-response reaction times or the regularity of ...

The different techniques and methods employed as well as the different quantitative and qualitative variables measured in order to objectify postural control are often chosen without taking into account the population studied, the objective of the postural test, and the environmental conditions. For these reasons, the aim of this review was to present and justify the different testing technique...

In this study, we examined the effects of sensory inputs of visual-vestibulosomatosensory conflict induced by virtual reality (VR) on subjective dizziness, posture stability and visual dependency on postural control in humans. Eleven healthy young volunteers were immersed in two different VR conditions. In the control condition, subjects walked voluntarily with the background images of interact...
