Quick responses to a loss of balance or “automatic postural responses”(APRs) are critical for
fall prevention. The addition of a distracting task—dual-tasking (DT), typically worsens …

Temporal-spatial, kinematic variability, and dynamic stability measures collected during
perturbation-based assessment paradigms are often used to identify dysfunction associated …

This study aimed to explore the ability to overcome unannounced surface perturbations of
different magnitudes during standing and walking under single-task and dual-task …

According to a worldwide WHO survey, about onethird of people at the age of 65 or older
experience at least one fall a year, which may result in a severe injury. Meanwhile, the …

Background Following mild traumatic brain injury, individuals often exhibit quantifiable gait
deficits over flat surfaces, but little is known about how they control gait over complex …

Background Most of older adults' falls are related to inefficient balance recovery after an
unexpected loss of balance, ie, postural perturbation. Effective balance recovery responses …

The dual-task (motor and cognitive) performance of eight older adults (72.0±6.4 years; 5
female; 3 male) was evaluated. Vocal choice reaction times (cognitive task) were measured …

A sudden underfoot perturbation can present a serious threat to balance during gait, but little
is known about how humans recover from such perturbations or whether their response is …

Background: Gait is considered a single task when done alone. Once an additional task as
talking is involved, it is referred to as dual task. This presents a cognitive load to the central …

Typically, humans plan foot placement 2-3 steps in advance; however, everyday complex
environments have elements that may disrupt anticipated foot placement. When foot …
