Study aim: The aim of the study was to determine connections between the functional asymmetry of limbs and the morphological asymmetry of feet. Material and methods: The study population consisted of 56 students: 30 females (mean age 20.29 ± 0.59 years) and 26 males (mean age 20.41 ± 0.78 years). The measurements of body build were taken with classical instruments. Body build was assessed on the basis of body height, body mass, and BMI. Seven features of the foot and 8 indices of foot arches were assessed. Assessment of laterality in upper and lower limbs was conducted on the basis of data from repeated interviews, and then verified with simple motor tests that imitated characteristic functions of the limbs. Asymmetry indices were calculated in order to determine asymmetries of the features. Mollison’s index was applied to assess dimorphic differences. Results: Features that were statistically different in the foot of the dominant limb and in the foot of the non-dominant limb were: among the group of females, the foot length without hindfoot, and the Clarke’s angle; among the group of males - the foot length without toes. Analyses of results of this study do not allow for a claim that laterality of lower extremities has a considerable impact on indices of longitudinal and transverse foot arches. Conclusions: The following conclusions were formulated on the basis of the conducted analysis regarding the group of subjects with homogeneous right laterality: - in females, the dominant limb’s foot is characterized by a shorter bone arm lever for dorsiflexors; - in males, the dominant limb’s foot is characterized by a shorter bone arm lever for plantaflexors.

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.
