Abstract
The aim of the study was to analyze the development of foot structure and the impact of longitudinal and transverse arching of the foot on the position of the hallux and fifth toe in preschool children. The study was carried out among 200 children aged 6 (100 G, 100 B). The research tool was the podoscope CQ-ST. The collected research results were analyzed with the use of the Mann–Whitney U test, Pearson Chi-square test and regression analysis. A statistically significant influence of the heel angle on the value of the varus angle of the fifth toe of the right (girls: p = 0.032; boys: p = 0.001) and left foot (girls: p = 0.004; boys: p = 0.005) was found. Boys’ feet are longer and wider than girls’ feet; moreover, they have a lower longitudinal arch. The frequency of longitudinal and transverse arch deformities of the feet, as well as valgus of the hallux and varus of the fifth toe do not depend on gender. In both sexes, decreasing the transverse arch of the foot has an influence on the severity of varus of the fifth toe. Changes in the height of the longitudinal foot arch does not affect the position of the hallux and fifth toe.
Highlights
The human foot is the base of support and acts as a propelling mechanism, imparting propulsion during locomotion
Our research has shown the effect of the transverse arch on the position of the fifth toe, both in girls and boys
The right and left feet are characterized by symmetry
Summary
The human foot is the base of support and acts as a propelling mechanism, imparting propulsion during locomotion It acts as a lever in the pre-swing phase and absorbs the rotations of individual segments of the lower limb in the stance phase [1,2,3]. Parcou [10] noted that the anterior metatarsophalangeal hypothenar corresponded on one side to the front of the “posterior static triangle of the foot” and on the other side to the back of the “front dynamic triangle of the foot”. This place concentrates all the impulses that drive the gait
