Abstract:
We studied age-related changes in gait and equilibrium in healthy subjects and patients with Alzheimer-type dementia. We also studied the relation between gait and falling in institutionalized patients with Alzheimer-type dementia. Among healthy subjects, higher age was associated with greater postural sway, slower walking speed, and shorter stride length, but age was not associated with stride-length variability. In patients with mild Alzheimer-type dementia, both postural sway and stride length-variability were greater than in healthy subjects. Among patients who had fallen, stride length-variability was high. Variability in gait may be useful in distinguishing normal age-related decreases in gait from those associated with disease.
