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 measurements after the psychotherapeutic intervention. The numbers represent the values of the comparisons. For demonstration of effect size, the -values are presented. Body sway significantly changed towards a healthy posture pattern. Sway in the horizontal plane was increased (indicated by the term sway with an upward arrow) and sway in the vertical axis was significantly reduced (indicated by the term sway with downward arrows) throughout every single posturographic condition.
