Correlation between postural sway during quiet standing and balance recovery after small perturbations

  • Description:
    Previous studies have found minimal correlation between postural steadiness during quiet standing and recovery of balance from a perturbation (Owings, Pavol et al. 2000; Mackey and Robinovitch 2005). These results may reflect differences in the governing postural control mechanisms involved in these two tasks. These studies, however, used relatively large perturbations that significantly challenged the postural control system in order to maintain balance. Investigating small perturbation in this regard may provide insight as to how the postural control system adapts to different tasks and difficult levels. The goal of the current study was to determine correlations between commonly used postural sway measures during quiet standing and measures of recovery from a small postural perturbation. We hypothesized that stronger correlations would exist with small perturbations as opposed to large perturbations used in previous studies (Mackey and Robinovitch 2005). We also hypothesized that there will be a difference in these correlations between young and older adults, which may indicate differences in the flexibility of the postural control system to adapt to different tasks.
