Postural stability depends on interactions between the musculoskeletal system and neural control mechanisms. We present a frontal plane model stabilized by delayed feedback to analyze the effects of altered stance width on postural responses to perturbations. We hypothesized that changing stance width alters the mechanical dynamics of the body and limits the range of delayed feedback gains that produce stable postural behaviors. Surprisingly, mechanical stability was found to decrease as stance…

Stability radius can quantify differences in the sensitivity of system behavior to parameter changes, and predict that narrowing stance width increases system robustness, and could aid in the design of devices and therapies for improving motor function.

Anticipatory adjustment of mechanical properties for motor stabilisation

It is predicted that when immobility or accuracy become critical, the nervous system should adjust the body mechanical properties so as to reduce this relative speed, and should additionally reduce neural feedback gains to prevent over-compensation.

Anticipatory coadaptation of ankle stiffness and sensorimotor gain for standing balance

A generic model of stabilisation with neural delays is studied to understand how the organism should adapt to challenging balance conditions, and shows that increases in either stiffness or neural delay must be coordinated with decreases in spinal sensorimotor gains, otherwise the feedback itself becomes destabilizing.

Extension of Stability Radius to Neuromechanical Systems With Structured Real Perturbations

Stability radii are compared for a model for human frontal plane balance controlled by a delayed proportional-derivative feedback to two types of perturbations: unstructured complex and weighted structured real and it is argued that stability radii can effectively be used to compare different control concepts associated with human motor control.

Computer Simulation of the Effects of Muscle Co-activation and Joint Stiffness on Postural Stability

Simulating the effect of intrinsic muscle stiffness and muscle co-activation on the postural stability using a musculoskeletal computer model subjected to support-platform perturbations showed that coactivation of muscles resulted in higher joint stiffness and higher postural Stability and that intrinsic muscle short-range stiffness contributed significantly toPostural stability.

Transfer of postural adaptation depends on context of prior exposure.

Results confirm that adaptation of anticipatory postural control is not affected by stance width, as long as the control remains within biomechanical limits, however, transfer of control between stance widths is affected by the initial context in which the task is learned.

Contribution of vision to postural behaviors during continuous support-surface translations

This work adapted a pseudorandom ternary sequence perturbation previously used in rotational support-surface perturbations to a translational paradigm, allowing it to concurrently examine the effects of vision, perturgation amplitude, and frequency on balance control and suggest that visual input, perturbators amplitude,and perturbants can concurrently and independently modulate postural strategies during standing balance.

Stance width changes how sensory feedback is used for multisegmental balance control.

The strong influence of stance width on sensory integration and neural feedback control implies that rehabilitative therapies for balance disorders can target different aspects of balance control by using different stance widths.

Sensorimotor integration for multisegmental frontal plane balance control in humans.

The proposed model refines the understanding of sensorimotor integration during balance control by including multisegmental motion and explaining how intersegmental interactions influence frontal plane balance responses.



Postural feedback responses scale with biomechanical constraints in human standing

The results indicate that postural adjustments can be described as a single feedback control scheme, with scalable heterogenic gains that are adjusted according to biomechanical constraints.

Influence of stance width on frontal plane postural dynamics and coordination in human balance control.

Results are inconsistent with the hypothesis that subjects made greater use of coordinated counter-phase upper and lower body motion in narrow compared with wide stance conditions, and the nonlinearity in narrow stance is likely caused by an amplitude-dependent sensory reweighting mechanism.

A robotic device for understanding neuromechanical interactions during standing balance control

It is shown through experimentation and analysis that changing stance width alters fundamental mechanical relationships important in standing balance control and requires a coordinated adjustment of delayed feedback control to maintain postural stability.

A feedback model explains the differential scaling of human postural responses to perturbation acceleration and velocity.

The results suggest that an invariant feedback law was used to generate the entire time course of muscle activity across a variety of postural disturbances.

Effect of stance width on multidirectional postural responses.

The results demonstrate that the horizontal force constraint exerted at the ground was lessened in the wide, compared with narrow, stance for humans, a similar finding to that reported by Macpherson for cats.

Human standing posture: multi-joint movement strategies based on biomechanical constraints.

Postural feedback scaling deficits in Parkinson's disease.

A feedback control model of body dynamics that could reproduce the postural responses of young subjects, elderly subjects, and subjects with PD showed that all three subject groups gradually scaled postural feedback gains as a function of perturbation amplitudes, and the scaling started even before the maximum allowable ankle torque was reached.

A human sensorimotor control model, compatible with previous work by others, was assembled that incorporates linearized equations and full-state feedback with provision for state estimation, and produces a control that reasonably matches experimental data.

A feedback model reproduces muscle activity during human postural responses to support-surface translations.

Results suggest that a common set of feedback signals related to task-level control of CoM motion is used in the temporal formation of muscle activity during postural control.
