Opis:: In this note we present a method for recognition of flatfoot abnormality with the help of some new shape-measure describing numerically this abnormality efficient enough. The proposed measure can be easily implemented and used for automatic flatfoot level diagnosis. Experiments carried out on a number of the plantograms, analysed using the computer programme prepared by first of the authors, proved the usefulness of this new approach.

Opis:: Purpose: Medial longitudinal arch (MLA) strengthening has been considered an important part of successful flatfoot treatment. But, to date, the biomechanical loading behavior of the medial arch in flatfoot has not been evaluated. This study aimed to evaluate the MLA moment, MLA deformation angle, foot kinematics and ground reaction forces (GRF) in both normal foot and flatfoot groups. Methods: Each participant’s foot was classified according to arch type using foot prints and radiographs. Twenty-eight non-obese adults (13 flatfeet and 15 normal feet) were involved. The biomechanics data were collected in a 3D motion analysis laboratory. The MLA biomechanics were calculated. Hindfoot and forefoot kinematics were also analyzed. Results: The flatfoot group had a significantly greater peak eversion MLA moment ( p = 0.005) and a smaller peak MLA deformation angle ( p < 0.05) during specific subphases. The peak of hindfoot plantarflexion ( p < 0.05) and internal rotation ( p < 0.05) and the peak of forefoot abduction ( p < 0.05) in the specific subphases were greater in the flatfoot group. The flatfoot group also had significantly smaller peak vertical GRF ( p < 0.05) during late stance and larger peak medial GRF ( p < 0.05) during mid stance. Conclusions: This study found a significantly greater eversion deforming force acting at the MLA structure, greater hindfoot and forefoot motion, less MLA flexibility and abnormal GRF in a flatfoot group during walking, which reflected the deficit of foot function in a flatfoot group.

Opis:: Deformities of the feet in children can influence not only optimal foot development but also the development of other body segments. The aim of the study was to compare the hip and pelvis kinematics in groups of children with and without valgus deformity of the hindfoot. Three groups of children participated in the study: bilateral hindfoot valgosity (11 children, age 5.4±1.4 years), unilateral hindfoot valgosity (14 children, age 5.6±1.6 years) and the control group (8 children). Hindfoot valgus was measured clinically during standing. Hindfoot valgosity was considered in the range of 6 to 20 degrees. Kinematic data from five trials for each child was obtained using the Vicon MX system (six infrared cameras, frequency 200 Hz, Vicon Motion Systems, Oxford, UK). The results of our study showed significantly higher pelvic anteversion during the whole gait cycle for both unilateral and bilateral hindfoot valgosity children and significantly higher hip external rotation during the first half of the stance phase in bilateral deformity. The differences in the hip and pelvis kinematics, when compared to the control group, are higher for the group with bilateral deformity than in the group with unilateral deformity.
