Usefulness of Step Length for Predicting the Onset of Frailty in Community-Dwelling Healthy Older Adults: A Prospective Cohort Study

Frailty is a common geriatric syndrome associated with adverse health outcomes. Although gait speed is widely recognized as a predictor of frailty, the contribution of other gait parameters remains unclear, particularly among initially robust older adults. This study aimed to examine the associations between multiple gait variables and incident frailty in community-dwelling older adults who were nonfrail at baseline.
