Journal ArticleDOI
Postural Orientation and Equilibrium: What Do We Need to Know About Neural Control of Balance to Prevent Falls?
TL;DR: The effective rehabilitation of balance to improve mobility and to prevent falls requires a better understanding of the multiple mechanisms underlying postural control.
Journal ArticleDOI
The uncontrolled manifold concept: identifying control variables for a functional task
John P. Scholz,Gregor Schöner +1 more
TL;DR: An operational meaning to ” controlled” and ”uncontrolled” is given and a method of analysis through which hypotheses about controlled and uncontrolled degrees of freedom can be tested is described, finding that, for the task of sit-to-stand, the position of the center of mass in the sagittal plane was controlled.
Journal ArticleDOI
The adaptations to strength training : morphological and neurological contributions to increased strength.
TL;DR: The gains in strength with HRST are undoubtedly due to a wide combination of neurological and morphological factors, although there is contrary evidence suggesting no change in cortical or corticospinal excitability.
Journal ArticleDOI
The Balance Evaluation Systems Test (BESTest) to Differentiate Balance Deficits
TL;DR: The theoretical framework, interrater reliability, and preliminary concurrent validity for this new instrument, the Balance Evaluation Systems Test (BESTest), which aims to target 6 different balance control systems so that specific rehabilitation approaches can be designed for different balance deficits are presented.
Journal ArticleDOI
Using psychometric techniques to improve the balance evaluation systems test: the mini-bestest
TL;DR: The new 14-item scale (dubbed mini-BESTest) focuses on dynamic balance, can be conducted in 10-15 min, and contains items belonging evenly to 4 of the 6 sections from the original BESTest.

Journal ArticleDOI
Parallel Organization of Functionally Segregated Circuits Linking Basal Ganglia and Cortex
TL;DR: The basal ganglia serve primarily to integrate diverse inputs from the entire cerebral cortex and to "funnel" these influences, via the ventrolateral thalamus, to the motor cortex.
Journal ArticleDOI
Functional architecture of basal ganglia circuits: neural substrates of parallel processing
TL;DR: Recent evidence indicating that a parallel functional architecture may also be characteristic of the organization within each individual circuit is discussed, which represents a significant departure from earlier concepts of basal ganglia organization.
Journal Article
Muscle and tendon: properties, models, scaling, and application to biomechanics and motor control
TL;DR: Their integrated ability to generate force statically and dynamically is studied by formulating a generic model of the "musculotendon actuator", which has only one parameter, the ratio of tendon length at rest to muscle fiberlength at rest.
Journal ArticleDOI
Central programming of postural movements: adaptation to altered support-surface configurations.
Fay B. Horak,L. M. Nashner +1 more
TL;DR: Exposing subjects to horizontal surface perturbations while standing on support surfaces intermediate in length between the shortest and longest elicited more complex postural movements and associated muscle activation patterns that resembled ankle and hip strategies combined in different temporal relations.
Journal ArticleDOI
Movement, posture and equilibrium: interaction and coordination
TL;DR: This chapter discusses anticipatory postural adjustments associated with equilibrium maintenance in the context of dual-modular approach to posture versus global approach to equilibrium.
