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 …

It is not well understood how older adults meet the combined locomotor demands of
obstacle avoidance at fast speeds as compared to obstacle avoidance under cognitive …

For older adults especially, to perform everyday activities safely, adaptive locomotion that
adjusts basic locomotion pattern according to the environmental features is critical. It is …

Obstacle crossing requires visuospatial working memory to guide the trailing leg trajectory
when vision in unavailable. Visuospatial working memory, as assessed with …

High foot elevation during obstacle crossing is viewed as a conservative strategy in older
adults, but excessive foot elevation may result in large mediolateral center of mass (CoM) …

When older adults step over obstacles during multitasking, their performance is impaired;
the impairment results from central and/or sensory interference. The purpose was to …

Background Fall injuries resulting from trips are a major health concern. Virtual reality (VR)
offers an effective way of training obstacle avoidance while walking due to its ability to …

Background An age-related decline in motor flexibility, which is the ability to synergistically
control the degrees of freedom of the body to ensure stable performance of a task, is a factor …

[Purpose] This study aimed to clarify the relationship between falls and lower leg motion
during obstacle crossing, in which stumbling or trip** is the most common cause of falls in …

Maintaining a consistent relationship between each footfall and the body's motion is a key
mechanism to maintain balance while walking. However, environmental features, for …
