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 …

Falls associated with tripping over an obstacle can be devastating to elderly individuals, yet
little is known about the strategies used for stepping over obstacles by either old or young …

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

Background. Falls during walking are often triggered when a foot contacts an obstacle in its
path. Yet little is known about the ability of individuals of any age to successfully negotiate …

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 Falls are a significant problem in the older population. Most falls occur during
gait, which is primarily regulated by foot placement. Variability of foot placement has been …

Background Gait variability is an early fall predictor. However, it is unknown how gait
variability of older adults at high risk of falls is affected by an obstacle negotiation task. We …

Background A large proportion of falls in older people occur when walking. Limitations in
gait adaptability might contribute to tripping; a frequently reported cause of falls in this group …

This systematic review and critical evaluation of the literature investigates whether advanced
age compromises obstacle crossing under unconstrained and time-constrained conditions …

Forty-seven percent of falling accidents in older adults are caused by tripping over
obstacles. Understanding what strategies are involved in obstacle negotiation in older adults …
