The paper investigates whether extending step length or stepping over perturbations is more energy-efficient during uneven walking, finding a velocity-dependent threshold for each strategy.

This study finds reduced alpha reactivity in Parkinson's disease patients compared to healthy controls, which correlates with increased gait variability.

This study examines how postural demands affect tactile perception in the lower limb in young and older adults, finding that higher postural demands reduce tactile sensitivity and increase sway.

This study investigates how vision and touch interact to stabilize postural balance during illusory self-motion, finding that visual motion perception influences balance stochasticity and that touch interacts with visual motion perception.

This study examines how physical activity affects neuromuscular control of gait in young and older adults, finding that less active older adults show worse gait mechanics due to changes in neuromuscular control and muscle properties.

This study evaluates differences in margin of stability (MoS) calculations using various base of support definitions and investigates the impact of anthropometric factors on MoS measures.

This paper investigates how age and partner body characteristics influence the balance stabilizing benefit of interpersonal touch across different sensory conditions.

This study compares arm and trunk motion in young and old adults during a slip, finding younger adults accelerate their arms faster and reduce center of mass excursion, potentially lowering fall rates.

This study shows that people adjust their walking and balance when facing virtual height threats to minimize the perceived risk of falling.

This study shows that increased step length variability during walking raises metabolic cost by 0.7% per 1% increase in variability.

This study examines how uneven terrain and dual-task walking affect walking speed in older adults, finding that sensorimotor function better predicts changes in uneven terrain walking speed than cognitive function.
