STEADFAST: Psychotherapeutic Intervention Improves Postural Strategy of Somatoform Vertigo and Dizziness

Table 1

Comparison of postural control in SVD patients and in healthy subjects. Significance levels as displayed by values for all different posturographic conditions ()–() and for all evaluated parameters (sway path = SP, root mean square of sway path = RMS) of the patients’ postural control at baseline in comparison to that of healthy controls. The numbers represent the values of the comparisons. Effect sizes are displayed by -values. Significantly reduced body sway was found for the horizontal plane as well as increased body sway for the vertical direction. In this context the term sway with an upward arrow indicates elevated sway values of the patients in comparison to the normal subjects; downward arrows indicate reduced sway values of the patients.
