Abstract

Abstract:

BACKGROUND: Pregnant women have a significantly higher risk of falls than non-pregnant women of the same age due to changes in body structure and hormone levels. Existing studies have shown that there is a close relationship between the change of gait characteristics and the occurrence of falls. Therefore, studying gait stability in different gestational periods has a great significance for the prevention of falls in pregnant women.
OBJECTIVE: To explore the gait characteristics of pregnant women in different gestational stages, and to provide suggestions for preventing the occurrence of falls of pregnant women.
METHODS: The study was approved by the Ethics Committee of Binzhou Central Hospital, approval No. 2018-039. The data of 20 pregnant women (pregnant group) and 20 non-pregnant women (control group) were collected. Gait kinematics data were collected in three stages: ≤12 weeks (early-term pregnancy), > 12-28 weeks (mid-term pregnancy) and > 28-40 weeks (late-term pregnancy). The gait characteristics of pregnant women in different gestational periods were discussed through the change of gait parameters.
RESULTS AND CONCLUSION: (1) There were significant differences in some gait parameters between patients before and after pregnancy. (2) There was no significant difference in gait data between early pregnant women and healthy controls (P > 0.005). (3) The pregnant women in mid-term pregnancy showed the reduced walking speed, shorter stride length, shorter step length; longer support time when compared with healthy control group for late pregnancy, compared with healthy control group, women’s also shown the reduced speed, longer stride length; longer step length and longer of gait cycle time. These changes are to maintain the stability of pregnant women, and to prevent falls.

Key words: pregnant women, different gestational periods, early-term pregnancy, mid- term pregnancy, late-term pregnancy, gait analysis, fall, gait stability
