This study investigated age-related differences in gait speed using wearable devices in a group of healthy younger (n=33, 18–40 years) and older (n = 32, 65–85 years) adults. In-lab gait speed measurements, regardless of the method used, failed to differentiate between age groups. However, at-home gait speed, derived from continuous monitoring, successfully distinguished between the groups. Only three days of at-home monitoring were sufficient to reliably estimate gait speed and capture age-related differences, suggesting that wearable devices may offer a more objective and naturalistic measure of functional ability for clinical trials.
