Plantar Pressure Distribution During and after Pregnancy and the Effect of Biomechanical Shoes
Bd.8,Nr.1(2017)
Background: The study is focused on objective data about plantar pressure changes during pregnancy and after birth, as well as the possibility to affect change in plantar pressure by wearing special biomechanical shoes developed in cooperation between Masaryk university and Hanak Company; Methods: Plantar pressure data of 38 pregnant women were measured in the first and third trimesters, and after birth with Emed-at plantographic platform. 21 of the subjects (experimental group) wore special biomechanical shoes during this period. Peak plantar pressure and pressure time integral values in 10 masks of the right and left foot were measured separately and processed through ANOVA and Tukey post – hoc tests; Results: The main findings were significant increases in plantar pressure values under the longitudinal arch and medial forfoot region during the pregnancy in both groups, and a decrease in most of the values after birth. There were no statistically significant differences in measured values between the groups; Conclusions: The load of the foot shifts during the pregnancy in a forward medial direction, which puts more loads on the longitudinal arch, medial metatarsal head areas and the big toe. After birth, the plantar pressure distribution patterns mostly return to the original state observed at the beginning of pregnancy. The effect of the biomechanical shoes on the foot was not proved.
