QUANTIFICATION OF FREE-LIVING MOBILITY IN COMMUNITY LIVING OLDER ADULTS USING WEARABLE SENSORS

摘要

With the advent of miniaturized body worn sensing technology it is now possible to collect and store data on different aspects of mobility under free-living conditions for long period of time. 88 older adults living in the community in Montreal (Canada) wore for 12 days a data logging platform incorporating a GPS receiver with an 3D accelerometer. location, activity, travel and Geospatial distribution of mobility were extracted and compared across participants using ICF measures body structures and function (cognitive status, depressive symptoms, body composition, pain), personal (age, gender, education, revenue) and environmental (social participation, living situation, walking access to shop and services, access to a car). Results suggest that the proposed mobility outcomes are sensitive to the different domain of the ICF with environmental variables contributing significantly to variation in mobility of community dwelling older adults. On-going studies are looking at how aging and disease affect these mobility outcomes.
