Cognitive performances better identify fallers than mobility assessment among older adults with fear of falling.

Background: Half of the people with fear of falling (FoF) are non-fallers, and the reason why some people considered non-fallers are afraid of falling is unknown, but reduced mobility or cognition, or both concurrently must be considered as potential risk factors.

Methods: Twenty-six older adults with FoF participated in this study.
