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 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 …

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 …

Objective: the present study investigated the effects of walking under different challenges
and kinematics and kinetics generated during these activities and how these vary with age …

BACKGROUND: Laboratory settings may differ from everyday life with respect to factors
such as attention, motivation, intention, and self-efficacy. Since those factors are likely to …

The aim of this research was to describe age-related changes in locomotor adjustments
during obstructed gait and expand and build from the current body of literature describing …

Transitioning from standing to walking requires equilibrium to be maintained while a forward
propulsive force is generated. The ability to manage these competing demands is …

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 The ability to adapt gait when negotiating unexpected hazards is crucial to
maintain stability and avoid falling. This study investigated whether impaired gait …

The ability to adapt to environmental and task demands while walking is critical to
independent mobility outside the home and this ability wanes with age. Such adaptability …
