Long-Term Wearable Monitoring in Older Adults: Feasibility, Usability, and Practical Implications for Real-World Trip Detection

BackgroundThe feasibility and usability of wearables during extended follow-up periods in living environments remain unclear.ObjectiveThis study examined the feasibility and usability of a wearable device for long-term trip monitoring in older adults.MethodsTwenty-five community-dwelling participants wore the device embedded in a belt for two months, returning weekly to the laboratory for battery and memory card replacement and completing technology-acceptance questionnaires. Participants also completed the System Usability Scale and the Intrinsic Motivation Inventory.ResultsAdherence was 68%, with 64% achieving the whole monitoring period. The main reasons for discontinuation included week-long trips and needing to remove the device for bathing. About 40% required at-home replacement due to transportation difficulties. Participants reported no trouble putting on the belt, though many forgot to wear it upon waking.ConclusionOverall, the wearable demonstrated good usability, but strategies are needed to improve long-term adherence and address barriers to sustained use.
