Abstract

Background and aims: The purpose of this study was to examine the center of pressure (COP) trajectory at gait initiation in single- and dual-task conditions between elderly Fallers and Non-fallers. Methods: Seventy-one community-dwelling elderly people (mean age 80.5±7.6 years) voluntarily participated in this study. Participants were categorized as Fallers or Non-fallers on the basis of previous fall experience. In single- and dual-task conditions, participants performed gait initiation trials from a starting position on a force platform while COP data were collected. Steady-state walking time on a 10-m straight walkway in single- and dual-task conditions was also measured. In the dual-task condition, participants performed individual tests with simultaneous backward counting. Maximum COP displacements and velocities were calculated in the anteroposterior and mediolateral directions. Results: In the dual-task condition, Fallers had significantly smaller backward displacements and slower backward velocities of COP than Non-fallers, although there was no significant difference in these values in the single-task condition between groups. Steady-state walking time was also not significantly different in both single- and dual-task conditions between groups. Conclusions: Gait-initiation performance in dual-task conditions may be a good discriminator between Fallers and Non-fallers.
