STEADFAST: Psychotherapeutic Intervention Improves Postural Strategy of Somatoform Vertigo and Dizziness
Table 2
Comparison of body sway activity in SVD patients and healthy subjects by fast Fourier transformation (FFT). Results: values of sway activity analyzed by a fast Fourier transform (FFT) in different frequency ranges. For characterization of effect sizes, the -values are also displayed. Significantly elevated body sway for the horizontal plane and the vertical direction was observed for frequencies up to 8 Hz; a significantly reduced body sway activity was observed in the high frequency range.
