[目的]从运动学角度探讨孕妇平衡策略的变化。[受试者] 8名孕妇和8名非孕妇参加。[方法]利用三维运动分析系统、2个测力板和10个红外摄像机对平衡策略进行运动学测量。使用三维运动分析系统分析功能性前伸测试（FRT）的性能。在每个妊娠期，非孕妇和孕妇之间的参数进行了比较，并在中期和晚期妊娠的孕妇之间。[结果]妊娠妇女的胎龄比非妊娠妇女短。在妊娠中期和妊娠晚期，孕妇的双侧髋关节伸展力矩小于非孕妇。妊娠晚期的女性双侧踝关节跖屈力矩大于非妊娠女性。在妊娠妇女中，右踝跖屈力矩在妊娠晚期大于妊娠中期。[结论]与非妊娠期相比，妊娠期前伸距离缩短，踝关节策略在保持平衡方面优于髋关节策略。
[Purpose] The purpose of this study was to elucidate changes in balance strategy during pregnancy from a kinematics perspective. [Subjects] Eight pregnant women and eight non-pregnant women participated. [Methods] A 3D motion analysis system, two force plates, and 10 infrared cameras were used to measure the kinematics of the balance strategy. The 3D motion analysis system was used to analyze performance of the functional reach test (FRT). Parameters were compared between non-pregnant women and pregnant women during each trimester, and between pregnant women in the second and third trimesters. [Results] The FRT of pregnant women was shorter than that of non-pregnant women. Bilateral hip joint extension moments were smaller in pregnant women in the second and third trimesters compared to non-pregnant women. Bilateral ankle plantar flexion moments were larger in pregnant women in their third trimester compared to non-pregnant women. In pregnant women, the right ankle plantar flexion moment was larger in the third trimester than in the second trimester. [Conclusion] These results suggest that forward reach distance is reduced, and that the ankle joint strategy takes precedence over the hip joint strategy in maintaining balance during pregnancy compared to non-pregnancy.
