When performing many daily activities, individuals must adopt body configurations,
orientations, and movements that allow upright stance to be maintained while other tasks …

Our activities of daily living inherently involve interacting with the physical environment. This
interaction involves both reactive (feedback) and proactive (feedforward) gait adaptations …

Falls are a major public health issue not only for older adults but also young adults, with fall-
related injuries occurring more frequently in adult females than males. However, the sex …

Falls are the third leading cause of unintentional injuries for ages 18–35 years (CDC), but
the causes and circumstances of falls in this age group are understudied. The purpose of …

Physics of Biological Action and Perception helps researchers interested in exploring
biological motor control from a physics or alternative viewpoint perspective. The book …

The purposes of this study were to determine if healthy older adults adopt strategies to
decrease the likelihood of obstacle contact, and to determine how these strategies are …

We applied the theory of synergies to analyze the processes that lead to unintentional
decline in isometric fingertip force when visual feedback of the produced force is removed …

Older adults commonly report muscle fatigue, which may be associated with reduced
walking ability. Elderly may have insufficient awareness of the balance threat caused by …

Background Age-associated physiological changes result in modified gait, such as slower
speed, for older adults. Identifying the onset of age-related gait changes will provide insight …

Background When step** over obstacles, analyses have focused on the successful trials
to understand adaptive gait. However, examination of the inadvertent trips that occasionally …
