Age and environment-related differences in gait in healthy adults using wearables

M. D. Czech, D. Psaltos, et al.

This exciting study explores how wearable devices reveal crucial age-related differences in gait speed among healthy adults. While traditional lab methods fall short, at-home monitoring succeeds in capturing the nuanced functional abilities of younger and older groups. The research highlights the power of technology in clinical trials, conducted by an expert team from Pfizer.

Abstract

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.
