Human Postural Control
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 assigned to compensate for internal or external pe...
متن کاملHuman Postural Control System
Instability, fear of falling and fall injuries are common problems for the older population and individuals with chronic disabilities. Development of screening tools and outcome measures of balance performance and fall risk has become of great interest for health professionals and researchers in the field of rehabilitation. Although linear modeling is desirable due to its simplicity, however, m...
متن کاملModeling and Control of Human Postural Sway
INTRODUCTION For quiet standing, the ankle strategy is used for the control of human posture in which the body moves as a rigid mass around the ankle joints. In its simplest form, the body is regarded as a single-link inverted pendulum with movement at the ankle joint controlled by the human postural control system. In patients with neurological impairment, this function might be restored by fu...
متن کاملSensory reweighting dynamics in human postural control.
Healthy humans control balance during stance by using an active feedback mechanism that generates corrective torque based on a combination of movement and orientation cues from visual, vestibular, and proprioceptive systems. Previous studies found that the contribution of each of these sensory systems changes depending on perturbations applied during stance and on environmental conditions. The ...
متن کاملHuman Postural Control : Force Plate Experiments
We report the results of time series analysis of human body sway while quiet upright stance. The bivariate records (stabilograms) are measured by means of a force plate. To investigate interrelations between oscillations in anterior{posterior and lateral directions we use several techniques: cross-spectrum analysis, generalized mutual information, and calculation of instantaneous relative phase...
