A foot is a complicated osteoarticular system. The complex structure and variability predispose it to the formation of foot deformity. The cause deformities of the feet are weakened muscle tissue and ligaments, systemic diseases: obesity, musculoskeletal defects, neurological diseases, rheumatism, diabetes, pregnancy, improper shoes or socks. They interfere with the function of the foot and are reflected in the distribution of support points. The aim of this study was to assess the impact of diabetes on pregnancy and the mechanics of the foot and the risk of developing diabetic foot. Material and methods: The study took part in healthy and diseased women with type 1 diabetes in pregnancy. Evaluation of static foot was performed using podoscope, made up of mirrors, lights and camera. The camera described the distribution of the pressure on the glass plate, which the person being investigated was standing on. It recorded the reflection of feet and transmit them to a computer. Description the results consisted of defining relevant indicators. The evaluation was performed using the dynamic pressure Parotec system, the measuring cylinder placed inside the patient‘s shoe provided with sensors recording the foot pressure distribution on the ground while standing and walking. The data were stored on a memory card loaded into the computer, where the analysis took place. It has been calculated the average values of pressures exerted on the various zones of the foot.
