Journal ArticleDOI
Ankle Muscle Stiffness in the Control of Balance During Quiet Standing
TL;DR: This research presents new data and reanalyzed information to refute the criticisms of the model of stiffness control during quiet standing and presents a new technique that directly estimates the muscle stiffness from the ankle moment and sway angle.
Journal ArticleDOI
Visual control of limb trajectory over obstacles during locomotion: effect of obstacle height and width
Aftab E. Patla,Shirley Rietdyk +1 more
TL;DR: The results revealed that the trajectory is substantially modulated for height changes but minimally for the width, provided the width of the obstacle does not force subjects to alter their step length.
Journal ArticleDOI
Balance recovery from medio-lateral perturbations of the upper body during standing
TL;DR: The goal of this study was to provide unique and novel insights into the underlying motor mechanisms used in postural control by determining the joint moments during balance recovery from medio-lateral (M/L) perturbations.
Journal ArticleDOI
Locomotor Patterns of the Leading and the Trailing Limbs as Solid and Fragile Obstacles Are Stepped Over: Some Insights Into the Role of Vision During Locomotion.
TL;DR: The results highlight the role of exproprioceptive input provided by the visual system and possible cognitive influences on the limb trajectory as one travels over uneven terrains.
Journal ArticleDOI
What guides the selection of alternate foot placement during locomotion in humans.
TL;DR: In this paper, a light spot of different shapes and sizes simulated an undesirable landing area. Participants were required to avoid stepping on this spot under different time constraints, and the foot placements were categorized into one of eight choices.
