Testing a theory-based mobility monitoring protocol using in-home sensors: a feasibility study

Abstract

Mobility is a key factor in the performance of many everyday tasks required for independent living as a person ages. The purpose of this mixed-methods study was to test a theory-based mobility monitoring protocol by comparing sensor-based measures to self-report measures of mobility and assess the acceptability of in-home sensors with older adults. Standardized instruments to measure physical, psychosocial, and cognitive parameters were administered to 8 community-dwelling older adults at baseline, 3-month, and 6-month visits. Semi-structured interviews to characterize acceptability of the technology were conducted at the 3-month and 6-month visits. Technical issues prevented comparison of sensor-based measures with self-report measures. In-home sensor technology for monitoring mobility is acceptable to older adults. Implementing our theory-based mobility monitoring protocol in a field study in the homes of older adults is a feasible undertaking but requires more robust technology for sensor-based measure validation.
