Research of non-contact anterior cruciate ligament (ACL) injury risk aims to identify
modifiable risk factors that are linked to the mechanisms of injury. Information from these …

To step over obstacles of varying heights, two distinct ongoing streams of activities—visual
exploration of the environment and gait adjustment—were required to occur concurrently …

Background Incorrect body weight shifting is a frequent cause of falls, and the control of the
whole-body center of mass (CoM) by segmental coordination is essential during walking …

A major problem in neurorehabilitation is the lack of objective outcomes to measure
movement quality. Movement quality features, such as coordination and stability, are …

Background Impaired movement stability is a common symptom of Parkinson's disease (PD)
that leads to falls and mishandled objects. Decline in synergistic stabilization of movement in …

Community ambulation requires gait adaptations to navigate environmental obstacles. It is
well known that while crossing obstacles, variables quantifying the gait pattern are …

Falls that occur while negotiating steps are a leading cause of death in older adults.
Although recent efforts have improved understanding of the mechanics and control of …

Walking patterns of persons affected by cerebellar ataxia (CA) are characterized by wide
stride-to-stride variability ascribable to: the background pathology-related sensory-motor …

The uncontrolled manifold hypothesis is a method used to quantify motor synergies, defined
as a specific central nervous system organization that maintains the task-specific stability of …

Motor flexibility, the ability to employ multiple motor strategies to meet task demands, may
facilitate ambulation in complex environments that constrain movements; loss of motor …
