Stepping over obstacles: gait patterns of healthy young and old adults.
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 adults. The… Expand
Effects of age and available response time on ability to step over an obstacle.
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 obstacles,… Expand
