| Outline of Final Research Achievements |
Individuals are exposed to repetitive dual-task-like situations in daily life, especially while walking. Thus, understanding how older adults adapt their walking-related motion under dual-task conditions is of clinical importance. The present study was conducted to investigate the association between dual-task-related changes (DT-changes) in lower-limb gait parameters and DT-changes in lower-trunk sway. Participants (older and younger adults) were asked to walk while performing an additional cognitive task, or with no additional task. During walking, lower-limb gait parameters and lower-trunk sway were measured using a photoelectric cell system and inertial sensors. In older adults, DT-changes in the temporal-lower-limb gait parameter stride time variability was mutually associated with DT-changes in lower-trunk sway. In contrast, in younger adults, DT-changes in the spatial-lower-limb gait parameter step width were mutually associated with DT-changes in lower-trunk sway.
