Background: Older adults aged 65 years and older, with Mini-Mental State Examination score ≥24, and ambulatory (with or without the assistive device) were included. Concern about falling was evaluated with Falls Efficacy Scale-International (FES-I) scores. Participants with high concern about falling were identified using the cutoff of FES-I ≥23. Participants’ motor capacity was assessed in standardized walking tests under single- and dual-task conditions. Participants’ mobility performance was measured based on a 48-h trunk accelerometry signal from a wearable pendant sensor.
