Introduction: Balance difficulties are one of the factors that have a negative impact on the daily activity of elderly people, which in turn lowers their quality of life. Aim: evaluation of the differences in static and dynamic postural stability in young, elderly and with vision loss women. Material and methods: Eighty-three female volunteers were divided into three groups: 26 young women (20,2 ± 1,75), 26 elderly (68,7 ± 7,55) and 15 pupils with vision loss (19,2±1,78). The following parameters were analysed from Accusway and BBS platforms.Results: A comparison of results with visual inspection between a group of young and elderly women showed statistically significant differences in terms of stabilogram ellipse area and maximal postural s way in ML direction. These two groups differ significantly in all parameters from BBS platform. The greatest differences are observed on a dynamic ground (p<0,001). Women with visual loss achieved the best results of path COP with eyes closed (37,01±6,73), the worst results were observed in a group of elderly women (49,59±21,04). They also did not perform any tasks on a dynamic ground without visual inspection. Women with visual loss achieved significantly worse results than young group. Conclusions: Greater balance control system involvement is observed in dynamic tests, which seem to be more appropriate and can detect disturbances earlier than static tests. Tests with changeable stability of the platform and without visual inspection that differentiate the groups seem to be particularly useful.
