This study examined the dual-task interference effects of complexity (simple vs. complex),
type of task (carrying a pitcher vs. tray), and age (young adults vs. 7–10 year old children) on …

Background Falls among community-dwelling older adults are often triggered by uneven
walkways. Joint coordination and its variability change with age and may place older adults …

Background Up to now there have only been marginal data in the elderly in need of care
regarding spatiotemporal gait parameters during single (ST) and dual tasking (DT). Aim The …

This study investigates whether the spatio-temporal parameters of gait in the elderly vary as
a function of walking distance. The gait pattern of older subjects (n= 27) over both short …

Poor gait is an important risk factor for falls and associated with higher morbidity and
mortality. It is well established that older age is associated with worse gait, but it remains …

Background Mobility often is tested under a low challenge condition (ie, over a straight,
uncluttered path), which often fails to identify early mobility difficulty. Tests of walking during …

Complex gait (eg, obstacle avoidance) requires a higher cognitive load than simple steady-
state gait, which is a more automated movement. The higher levels of the central nervous …

Obstacle crossing, such as stepping over a curb, becomes more challenging with natural
aging and could lead to obstacle-related trips and falls. To reduce fall-risk, obstacle training …

Background Ageing brings profound changes in walking gait. For example, older adults
reduce the modification of pelvic and trunk kinematics with walking speed. However, the …

Background Age-related gait changes may play a critical role in functional limitations of
older adults. Despite sizable interest in determining how age alters walking mechanics …
