Background: From the perspective of dynamic postural control, the separation between the Center of Foot Pressure (COP) and the Center of Mass (COM) has been linked to COP-COM coordination. Therefore, investigating the role of COP-COM coordination during acceleration in gait initiation is important. This study investigated whether COP- COM coordination was involved in acceleration control during gait initiation in community-dwelling elderly people.
Methods: Young (n=11; age: 22.2 ± 1.4 years) and healthy elderly (n=23; age: 71.9 ± 4.3 years) subjects walked a 12 m gait 5 times at a self-selected speed. The gait velocity from the first to third step and COM were detected using 15 markers on the subject’ s body via a motion capture system. COP was traced by a 2.4 m foot pressure distribution sensor. ‘COP-COM separation.. View More»
