Introduction: The pregnant woman's body promotes many changes, including their biomechanics. The hormonal action which increases the laxity causes structural changes in the static and dynamic skeleton. Other factors, such as weight gain, growth of the uterus and the breasts, will help changing the gravitational forces of the pregnant woman and cause large static and dynamic postural adjustments in pregnant women. The startup of gait position is the transition from quasi-static to the first step. It is a task that challenges the postural control, because the demands on the neuromuscular system are increased at the beginning of the march, since it is required a complex integration of neural mechanisms, muscle activity and biomechanical forces. Objective: describe the oscillation amplitude and mean velocity of center of pressure during startup of gait, to compare the behavior of the center of pressure between the three groups at different gestational periods, verify that the changes in the behavior of the center of pressure along the pregnancy is at risk dynamic stability for pregnant women. Methods: A total of oscillation amplitude and velocity of displacement of center of pressure during startup of gait in 57 low-risk pregnancies in three trimesters. Results: Significant differences were found when comparing the groups 1º trimester and 3º trimester for the variable amplitude of oscillation mediolateral and mediolateral displacement speed. Discussion: Pregnant women tend to decrease the amplitude of oscillation mediolateral and mediolateral displacement speed during gestation. Conclusions: The amplitude of oscillation anteroposterior and mediolateral displacement speeds and respective of the first quarter from the third there was, on average, a gradual decrease to a platform and to the platform 2. There were significant differences in the oscillation amplitude variables mediolateral and mediolateral displacement speed when comparing the groups 1° trimester and 3° trimester, being higher in 1º trimester for both variables. The variables analyzed showed minor differences and do not constitute an imminent risk to the dynamic stability of the pregnant woman.
