摘要：

We estimated long-range correlations in the dynamics of sway during prolonged human standing. Two methods were used in this estimation: detrended fluctuation analysis (DFA) and power spectral analysis. Both methods yielded similar results: we observed long-range correlations with single scaling exponents over a broad range, from 10 a to 10 min, of standing. (C) 2001 Elsevier Science B.V.
