dc.description.abstractOlder adults experience increased fall risk, which may be influenced by distractibility. This study examines the effects of cognitive distractions on interlimb synchronization and balance in young and older adults. Participants performed quiet standing trials on separate force plates under eyes-open and eyes-closed conditions, with and without cognitive distraction (counting by ones, backward by sevens). Interlimb synchrony was assessed using cross-correlation (CCF) of center of pressure (COP) movements, while root mean square (RMS) sway and mean sway velocity (MSV) were also analyzed. It was hypothesized that cognitive distractions would reduce synchrony, particularly in older adults. Results showed no significant differences in CCF or RMS across groups or conditions, but MSV varied significantly across conditions. These findings suggest that while cognitive distractions affect postural sway velocity, they do not significantly impact synchrony or RMS under these conditions. This study enhances our understanding of balance-cognition interactions in aging.
