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

Key Points

• Step length serves as an effective predictor of frailty onset in older adults.
• Participants with shorter step lengths showed a higher frailty risk over a year.
• Cohort study assessed the relationship between physical function and frailty development.
• Findings support the need for early intervention strategies based on physical measurements.
