摘要: A healthy biological system is characterized by a temporal structure that exhibits fractal properties and highly complex. Unhealthy systems demonstrate lowered complexity either greater or less predictability in the of time series. The purpose this research was to determine if support surface translations with different structures would affect center pressure (COP) signal. Eight young participants stood on force platform translated anteroposterior direction for input conditions varying complexity: white noise, pink brown sine wave. Detrended fluctuation analysis used characterize long-range correlations COP series AP direction. Repeated measures ANOVA revealed differences among (p < 0.001). complex resulted compared normal standing. quadratic trend demonstrated an inverted-u shape across increasing order ability influence postural control through can have important implications rehabilitation.
