Human balance and posture control during standing and walking
TLDR
The inverted pendulum model permitted us to understand the separate roles of the two mechanisms during these critical unbalancing and rebalancing periods and confirmed the critical importance of the hip abductors/adductors in balance during all phases of standing and walking.About:

Journal ArticleDOI
The condition for dynamic stability
TL;DR: The well-known condition for standing stability in static situations is that the vertical projection of the centre of mass should be within the base of support (BoS), and an extension of this rule is proposed for dynamical situations.

Active control of lateral balance in human walking
Catherine E. Bauby,Arthur D. Kuo +1 more
TL;DR: The results imply that humans may harness passive dynamic properties of the limbs in the sagittal plane, but must provide significant active control in order to stabilize lateral motion.
Journal ArticleDOI
Assessment of spatio-temporal gait parameters from trunk accelerations during human walking
Wiebren Zijlstra,At L. Hof +1 more
TL;DR: The duration of subsequent stride cycles and left/right steps, and estimations of step length and walking speed can be obtained from lower trunk accelerations, which can be the basis for an analysis of other signals within the stride cycle.
Journal ArticleDOI
What is balance
TL;DR: Clinical definitions of balance and postural control are introduced and the act of maintaining, achieving or restoring a state of balance during any posture or activity is defined.
Journal ArticleDOI
Acceleration patterns of the head and pelvis when walking on level and irregular surfaces.
TL;DR: Findings suggest that one of the primary objectives of the postural control system when walking on irregular surfaces is head control, and that subjects adapt their stepping pattern on irregular surface to ensure that the head remains stable.

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.

Open-loop and closed-loop control of posture: A random-walk analysis of center-of-pressure trajectories
James J. Collins,C. J. De Luca +1 more
TL;DR: This work strongly supports the position that much can be learned about the functional organization of the postural control system by studying the steady-state behavior of the human body during periods of undisturbed stance.
Journal ArticleDOI
Properties of postural adjustments associated with rapid arm movements
P. J. Cordo,L. M. Nashner +1 more
TL;DR: Postural muscle synergies were equivalent in muscle composition, relative activation magnitudes, and relative temporal sequencing and a conceptual model is proposed that suggests one simple way in which the reciprocal influence of postural set on postural and focal movement components and their temporal sequencing might be accomplished.

Muscle Architecture of the Human Lower Limb
TL;DR: The architectural features of the major knee extensors and flexors and ankle plantarflexors and dorsiflexors were determined in three human cadavers and grouped according to whether they showed a predilection for tension or velocity of shortening.
