Influence of stance width on frontal plane postural dynamics and coordination in human balance control.
The influence of stance width on frontal plane postural dynamics and coordination in human bipedal stance was studied. We tested the hypothesis that when subjects adopt a narrow stance width, they will rely heavily on nonlinear control strategies and coordinated counter-phase upper and lower body motion to limit center-of-mass (CoM) deviations from upright; as stance increases, the use of these...
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 کاملBalance control strategies during perturbed and unperturbed balance in standing and handstand
Insights into sensorimotor control of balance were examined by the assessment of perturbed and unperturbed balance in standing and handstand postures. During perturbed and unperturbed balance in standing, the most prevalent control strategy was an ankle strategy, which was employed for more than 90% of the time in balance. During perturbed and unperturbed balance in handstand, the most prevalen...
متن کاملBalance Control of a Bikebot for Studying Human Dynamic Postural Balance Motor Control
We present the development of the gyroscopicbalanced control of an autonomous bikebot. The bikebot is an actively controlled bicycle-based robotic platform developed to study human dynamic postural balance motor skills through unstable physical human-robot interactions. We first present a dynamic model and analysis for the bikebot. A nonlinear balancing controller is designed to stabilize the u...
متن کاملHuman 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...
