Background:‪The overall purpose of this study is to define differences in the symmetry of stabilizing function of lower limbs in geriatric women compared to younger females. Material and methods:‪The study evaluated 30 female seniors (aged 82.9 ±6.1), 39 female university students (aged 23.3 ±0.4) and 33 girls (aged 7.4 ±0.3). Stability was evaluated using a stabilographic platform CQ Stab (Electronic System), with the subject standing with eyes open. Anova Kruskal-Wallis test and Wilcoxon test were used for the analysis. Results:‪The average percentage differences in limb loading (LLA) show a slight, not exceeding 2.5% asymmetry in the distribution of body weight. There was no statistically significant intergroup variation in this range. In extreme age groups asymmetry of indicators of the movement of the center of foot pressure (SPML MVML) was observed. Conclusions:‪The shift in asymmetry of mass distribution towards the right lower limb (non-predominant) observed in the elderly women might point to tendencies for greater involvement of the limb which is less affected by the ageing processes. This, however, needs further investigation. The asymmetry of activity in the lower limbs in the stabilization function in elderly people needs to be offset through exercises improving somatosensory mechanisms of balance control.
