Abstract:

BACKGROUND: Pregnancy is a special period for a woman because the posture change and body mass gain take inconvenience to the life. Thus, the physical condition of this special group should be highly concerned from the whole society.
OBJECTIVE: To explore the gait features of different gestational periods in pregnancy women in order to support pregnancy exercise and give suggestions for pregnant women shoes design.
METHODS: The dynamic foot pressure during the natural walk in pregnant 12, 21, 30 and 36 weeks were analyzed by foot pressure analysis system, and the cycle phase, intensity of pressure, and feet control were observed.
RESULTS AND CONCLUSION: The proportions of support time and double support time in gait cycle were increased following the gestational periods, however the amplitudes were diminished. The supinational spots (M3 and M2) of maximal intensity of pressure were increased gradually during gestation. The time of forefoot push off phase also showed the increasing tendency in gestational period. In order to improve the feet discomfort during physical activity and fitness exercise of pregnant women, we recommend that design and develop pregnant women-only fitness shoes according to the different gait characteristics during the natural walking gait.
