[Evaluation of gait initiation in low risk pregnant women in the three trimesters].
OBJECTIVE
To describe the process of gait initiation of pregnant women and to compare the behavior of the pressure center in the three trimesters of pregnancy.


METHODS
Fifty-seven low-risk pregnant women were evaluated, aged 18 to 35 years, selected for convenience location during the three trimesters of pregnancy. The women were divided into three groups of 19 subjects each, according to gestational age - 1st quarter (4-12 weeks), 2nd quarter (13-28 weeks), and 3rd quarter (29-42 weeks,). Each patient was positioned standing up with one foot on each AMTI force platform until she heard a beep indicating that she should start walking a distance of four meter. Data were analyzed using the SPSS software. The Kolmogorov Smirnov test, Tukey's test and Spearman correlation coefficient were used for group comparisons, with 5% significance level in all tests.


RESULTS
Significant differences were found between the 1st quarter (GFT) and 3rd quarter (GTT) groups regarding mediolateral oscillation amplitude (GFT: 0.4 cm and GTT: 0.2 cm) and mediolateral displacement rate (GFT: 0.9 cm/s and GTT: 0.4 cm/s). There was a gradual decrease in anteroposterior and mediolateral oscillation rate, and in the speed of displacement from platform 1 to platform 2 in GFT. There was a significant difference in oscillation amplitude and mediolateral displacement speed between GFT and GTT.


CONCLUSIONS
The variables analyzed showed minor differences and do not constitute an imminent risk for the stability dynamics of pregnant woman.
