Gait changes over time in hospitalized older adults with advanced dementia: Predictors of mobility change

People with dementia are at risk of mobility decline. In this study, we measured changes in quantitative gait measures over a maximum 10-week period during the course of a psychogeriatric admission in older adults with dementia, with the aims to describe mobility changes over the duration of the adm...
