There have been few studies of the way women walk in pregnancy, though some of the causes of low back ache of which they complain have only been partially worked out. This is why this study has been carried out on ten women between the third and eighth month of pregnancy. The speed at which they walk and the parameters of the gait as well as the localization of the centre of gravity when keeping upright have been measured in these pregnant women as well as in twenty control women of the same age. The results show that the speed at which they walk whether with or without carrying a weight usually is identical at the beginning and the end of pregnancy. When walking normally the size of the steps taken are no larger in pregnant women than in the control patients (p less than 0.05). Though the results are not statistically significant the rhythm of the steps is faster as well as their being a reduction in the length of the steps between the third and eighth month of pregnancy. When carrying a weight the length of the steps does not change greatly with pregnancy (p less than 0.05) and it would seem therefore to be a good way of assessing the changes that locomotion undergoes in pregnancy. The fact that women do not walk faster or slower can give evidence that they adapt to the change in posture that happens in pregnancy and they make the best possible biomechanical use of the parameters of walking in order to economise total energy output of the organism.(ABSTRACT TRUNCATED AT 250 WORDS)
关于孕期女性行走方式的研究较少,尽管她们所抱怨的下背痛的一些原因仅得到了部分解决。这就是对10名处于妊娠3至8个月的女性进行这项研究的原因。已对这些孕妇以及20名同龄对照女性测量了她们行走的速度、步态参数以及站立时重心的位置。结果表明,她们行走时无论是否负重,在妊娠开始和结束时的速度通常是相同的。正常行走时,孕妇迈出的步幅并不比对照患者大(p小于0.05)。尽管结果在统计学上不显著,但步频更快,且在妊娠3至8个月期间步长缩短。负重时,步长随妊娠变化不大(p小于0.05),因此这似乎是评估孕期运动变化的一种好方法。女性行走速度不变这一事实表明她们适应了孕期发生的姿势变化,并尽可能从生物力学角度利用行走参数,以节省机体的总能量输出。(摘要截选至250词)
