Abstract(s)
The kinematic analysis of gait during pregnancy provides more information about the anatomical changes and contributes to
exercise and rehabilitation prescription. The purposes were to quantify the lower limb kinematics of gait and to compare it between
the second and third trimesters of pregnancy and with a control group. A three-dimensional analysis was performed in twentytwo pregnant women and twelve nonpregnant. Repeated Measures and Manova tests were performed for comparisons between
trimesters and between pregnant and controls. The walking speed, stride width, right-/left-step time, cycle time and time of
support, and flight phases remain unchanged between trimesters and between pregnant and controls. Stride and right-/left-step
lengths decreased between trimesters. Double limb support time increased between trimesters, and it increased when compared
with controls. Joint kinematics showed a significant decrease of right-hip extension and adduction during stance phase between
trimesters and when compared with controls. Also, an increase in left-knee flexion and a decrease in right-ankle plantarflexion were
found between trimesters. The results suggested that pregnant women need to maintain greater stability of body and to become
more efficient in locomotion. Further data from the beginning of pregnancy anthropometric data may contribute to the analysis.
