Objective: To test the hypothesis that increased gait variability predicts falls among community-living older adults attending an outpatient clinic.Design: Prospective, cohort study.Setting: Three outpatient geriatric clinics.Participants: Fifty-two community-living, ambulatory men and women aged greater than or equal to 70 years.Interventions: Not applicable.Main Outcome Measures: Subjects walked at a normal pace for up to 6 minutes wearing force-sensitive insoles that measured the gait rhythm on a stride-to-stride basis. Afterward, subjects reported fall status on a weekly basis for 1 year. The primary outcomes were the association between measures of the stride-to-stride fluctuations in gait rhythm and (1) subsequent falls during a 12-month follow-up period and (2) potential contributing factors.Results: Almost 40% of the subjects reported falling during the 12-month follow-up period. Stride time variability was 106 +/- 30 ms in subjects who subsequently fell (n = 20) and 49 +/- 4ms in those who did not experience a fall (n = 32) during the 12-month follow-up period (p
