BACKGROUND: The hip joint is a complex anatomic structure which provides both stability and mobility, and is involved in transferring the weight of the body. During pregnancy the increased mass of the female abdomen increasing the torque exerted by the upper body around the hip joints.
AIM: We took a longitudinal perspective to explore the interactions between base of support size and kinematics of the hip joint throughout gait cycle in pregnant women referring it to the non-pregnant state of the same group. We were interested in how wide-step walking due to pregnancy would affect the hip joint and pelvis mechanics.
MATERIAL & METHODS: 16 women participated in five experimental sessions arranged according to the same protocol (before, in the first, second, third trimester of pregnancy and postpartum). First, the anthropometric measures were taken, then walking trials were registered. Gait parameters and changes in hip/pelvis movements were analyzed.
RESULTS: On average, general gait parameters were similar across all sessions. The most significant changes in hip/pelvis movements throughout pregnancy consisted in progressive augmentation of the range of hip rotations, hip flexion and pelvis tilt. These changes correlated with increments in the base of support. Abdominal mass gain correlated with increased range of hip rotation, supporting a link between mass distribution and hip kinematics.
CONCLUSIONS: The range of motion of pelvis movements (anterior tilt, obliquity, yaw rotation) and hip joint oscillations in the sagittal and frontal planes remained similar throughout pregnancy. Nevertheless, significant changes in hip/pelvis mechanics (max hip flexion, reduced hip extension, max pelvis tilt and the range of hip rotation) occurred during pregnancy, although they returned to prior gestation parameters postpartum.
