A number of important health-related outcomes are directly related to a person's ability to maintain normal gait speed. We hypothesize that cellular telephones may be repurposed to measure this important behavior in a noninvasive, continuous, precise, and inexpensive manner.

Publication Date: 
Feb 14, 2011

OBJECTIVES: To describe a system that uses off-the-shelf sensor and telecommunication technologies to continuously measure individual lifespace and activity levels in a novel way.

DESIGN: Proof of concept involving three field trials of 30, 30, and 21 days.
