ABSTRACT
Eleven pregnant women (age: 33.20 ± 1.62 years; Range: 32 to 37 years), perform anthropometric and kinematical collections in optoelectronic system with 12 infrared cameras at a frame rate of 500 Hz, and 3 force platforms (2 Kistler and 1 AMTI), synchronized at the same file. Markers were placed according Visual 3D (V3D) setup, for the lower limbs, and according to CODA setup of markers for pelvis segment. The trajectory of the reflective markers was smoothed using a Butterworth low-pass filter with a 10 Hz cut-off. Considering the four phases in analysis, kinematic pattern curves were estimated relative to the walking stride cycle. The gait cycles were selected based on both feet GRF data and the heel markers pattern recognition. All data were normalized in time.
