## 3 Results  
Table 1 contains the median values and the tolerance ranges with lower and upper limits as well as the confidence intervals with the left and right limits of the posturographic parameters. The rear foot had a greater balance distribution of 66.67% than the forefoot (33.33%). In addition, there was an approximately equal loading of both feet with the left foot being 52.33% and the right being 47.67%. The increased left loading resulted mainly from the forefoot loading which was found to be more pronounced on the left side (19.33%/13.00%). The frontal variation of 11 mm was less than the sagittal variation of 16 mm. Accordingly, the ellipse area was found to be 1.17 cm\({}^{2}\), with a width of 0.91 cm and a height of 0.40 cm. Table 1 Examination of the demographic parameters (age and BMI) (Table 2) revealed a significant positive correlation (\(p\leq 0.04\); rho: 0.21) between age and sagittal sway with a weak effect. Positive correlations were also observed (\(p\leq 0.04\) and 0.02, respectively; rho: 0.21 and 0.24, respectively) between age and the ellipse area and between age and the ellipse width with a weak effect size. There were no significance differences between the other parameters and age. The significant, positive correlations with low effect strength related to age are illustrated in Figure 2. The graphs show that with increasing age the sagittal sway increased, as well as the ellipse area and width. However, with respect to BMI (Table 3), no significant correlation between the BMI and posturographic parameters could be demonstrated (\(p>0.05\); low effect size). \begin{table}
