[Gait force propulsion modifications during pregnancy: effects of changes in feet's dimensions].

PURPOSE

to analyze the gait propulsion force and relate it to changes in the dimensions of the feet and to the influence on the quality of life of pregnant women.

METHODS

two groups were studied, a control (C) one consisting of 20 non-pregnant women and a group of 13 pregnant women investigated during the three gestational trimesters (Gfirst, Gsecond, Gthird). The groups were subjected to an initial assessment; evaluation of gait propulsion force using the force platform (Bertec); measurement of foot length and width; assessment of perimetry by the figure eight method; and assessment of quality of life using the World Health Organization Quality of Life Instrument Bref (Whoqol-bref). The Mann-Whitney test was used to evaluate differences between group C and Gfirst, the Friedman test was used to determine differences between Gfirst, Gsecond and Gthird, and the Wilcoxon test was applied to significant cases. The level of significance was set at 5%.

RESULTS

There was an increase in body mass (10.5 kg) and ankle edema (2.4 cm) during pregnancy. There was a decrease of gait propulsion force (10% of body mass) and an increase of mediolateral sway (10% of body mass) compared to Control Group. There was a reduced quality of life among pregnantwomen, especially in the physical domain.

CONCLUSIONS

Gait disorders occur during pregnancy, which can increase the risk of falls and musculoskeletal discomfort, which may affect the quality of life of pregnant women.
