Does the effect of walking balance perturbations generalize across contexts?
HUMAN MOVEMENT SCIENCE, 93.
author keywords: Stability; Gait; Control
TL;DR:
The purpose of this study was to determine if the effect of balance perturbations on instability generalizes across contexts, and found no "goldilocks" perturbation paradigm to endorse that would support universal interpretations about locomotor instability.

Time-dependent tuning of balance control and aftereffects following optical flow perturbation training in older adults
JOURNAL OF NEUROENGINEERING AND REHABILITATION, 16.
MeSH headings : Aged; Biomechanical Phenomena; Female; Humans; Male; Muscle, Skeletal / physiology; Physical Therapy Modalities; Postural Balance / physiology; Sensation Disorders / rehabilitation; Walking / physiology
TL;DR:
Investigation of the propensity for time-dependent tuning of walking balance control and the presence of aftereffects following a single session of optical flow perturbation training suggests that older adults respond to the onset of perturbations using generalized anticipatory balance control, deprioritize that strategy following prolonged exposure to perturbATIONS, and exhibit short-term aftereeffects that indicate a lessening of anticipatory control, an increase in reactive control, and/or increased balance confidence.

TL;DR:
It is found that subjects did not minimize errors between the visual perception of movement and actual movement of the head and trunk, and lasting reductions in mediolateral postural sway may have implications for using error-augmented optical flow to enhance the integrity of walking balance control through training, for example in older adults.

Does local dynamic stability during unperturbed walking predict the response to balance perturbations? An examination across age and falls history

author keywords: Balance; Elderly; Lyapunov; Stability
MeSH headings : Accidental Falls / statistics & numerical data; Adult; Aged; Female; Humans; Locomotion / physiology; Male; Middle Aged; Postural Balance / physiology; Walking / physiology; Young Adult

author keywords: variability; push-off; balance; walking speed; biofeedback; ageing
TL;DR:
It is found that young adults adopt an FP at their preferred walking speed that maximizes dynamic stability, and the onset of a diminished push-off in old age may independently contribute to poorer balance control and precipitate slower walking speeds.

MeSH headings : Achilles Tendon / physiology; Adolescent; Adult; Humans; Locomotion; Young Adult
TL;DR:
The objective was to compute tendon work loops and hysteresis losses using these two Direct tendon kinematics estimates during human walking and found that Direct estimates generally resulted in negative work loops, suggesting that Direct approaches provide more plausible estimates than the Indirect approach, and may be preferable for understanding tendon energy storage and return.
