Stride Length Variability

Stride length variability is a measure of the inconsistency of each stride length over an activity. A highly variable stride length can be an indicator for cognitive disfunction.

Stride Length Variability and Alzheimer's - Patients who had a fall showed higher stride length variability than those who did not, and those who had more severe dementia were observed to have a significant difference in stride length variability than those with more mild dementia.
