One walk a year to 1000 within a year: Continuous in-home unobtrusive gait assessment of older adults

Highlights ► Current lab or clinic based walking speed assessments do not reflect everyday gait function. ► We show walking speed can be measured multiple times a day in home using unobtrusive passive sensing. ► Prior unattainable metrics-periodicity, variability, minimum and maximum speeds are capt...

Description
Summary:Highlights ► Current lab or clinic based walking speed assessments do not reflect everyday gait function. ► We show walking speed can be measured multiple times a day in home using unobtrusive passive sensing. ► Prior unattainable metrics-periodicity, variability, minimum and maximum speeds are captured. ► Home speed maps to standard clinical cognitive and motor measures. ► In home walking assessment is an ecologically valid measure of everyday gait function.
