Особенности походки детей с плосковальгусной деформацией стоп

Abstract

Abstract The problem of flat foot is one of the main directions in the practice of modern orthopedics. The progression of local lesions of the feet leads to the development of pathological processes in all large joints of the lower extremities and in the spine. Purpose. To determine the features of the gait of children with flat foot deformity. Twelve healthy children and eleven children with a diagnosis of valgus flat foot deformity at the age of 11-14 years were examined. The instrumental base of the study was the motion capture system from Vicon (Great Britain). The main parameters of the gait cycle, as well as the kinematic parameters, such as the angular movement of the foot in the ankle joint, have been investigated. In the group of healthy children higher cadence values (124 ± 7.07 steps / min) were noted compared with the second group (110 ± 10.04 steps / min), the duration of the double support period (0.22 ± 0.17 sec and 0 , 37 ± 0.41 sec, respectively). The dynamics of the supination and pronation angles of the foot in children with flat foot deformity coincide with the same dynamics in healthy children, however, throughout the entire gait cycle, they have a decrease in the average values of all the dynamic parameters under study. Conclusions. Gait analysis in healthy children and with flat foot deformity revealed significant differences in the duration of periods of single and double support, length, width and half-step time, as well as cadence. The kinematic and kinetic parameters in the gait cycle change parallel in both groups, however, the angular movements of the foot in the frontal plane in children with flat foot deformity showed a significant increase(decrease) in pronation in all events of the gait cycle compared to the group of healthy children.
