Toward Using Smart Watch to Monitor Frailty in Hospital Setting—Using a Single Wrist Wearable Sensor to Assess Frailty in Bedbound Inpatients

摘要

BackgroundWhile various objective tools have been validated for assessing physical frailty in the geriatric population, these are often unsuitable for busy clinics and mobility-impaired patients. Recently we have developed a Frailty Meter (FM) using two wearable sensors, which allows capturing key frailty phenotypes (weakness, slowness, and exhaustion), by testing 20-second rapid elbow flexion-extension test.
