Correlations between initial transient response and whole-trial estimates of postural control in eyes closed stance

Transient responses and whole-trial estimates of commonly used center of pressure parameters have been reported to provide clinically-relevant insight into postural control. In this study, correlations between transient features of commonly used center of pressure parameters and whole-trial estimates were tested for eyes closed stance in a healthy population. Changes in time-dependent, transient estimates of balance measures were no more than weakly correlated with traditional whole-trial estimates, whereas power-fit coefficients for the transients showed small-medium correlations with whole-trial estimates. Transient characteristics may provide unique information that is not captured by traditional whole-trial estimates.
