Background

Diabetes can cause biomechanical alterations that may be responsible for additional changes to those existing in a regular gestational period. The way a maternal body responds when affected by diabetes has not been clearly understood. This study aimed to describe the influence of type 1 diabetes on pregnant women's postural control.

Methods

Forty pregnant women in their third gestational trimester were allocated in two equal groups - the control group and the type 1 diabetic group. The variables related to postural control and balance were assessed using photogrammetry (head protrusion; cervical lordosis; thoracic kyphosis; lumbar lordosis; pelvic anteversion, knee flexion, tibiotarsal and foot inclination angles were measured), and baropodometry (anteroposterior and mediolateral distance trajectory of the center of pressure, amplitude and average speed of displacement of the center of pressure).

Findings

The results of the type 1 diabetic group showed, in the postural analysis, lower head protrusion and pelvic anteversion angles, while there was higher cervical lordosis, thoracic kyphosis, and lumbar lordosis angles. In the baropodometry, the anteroposterior distance and the amplitude of the center of pressure displacement with eyes open and closed were higher.

Interpretation

The findings suggest that type 1 diabetes mellitus in the third trimester of pregnancy is associated with postural changes, a decrease in the active ankle range of motion and increase in the anteroposterior oscillation of the center of pressure, with negative repercussions for postural control.

1 型糖尿病对妊娠晚期女性姿势控制的影响。

 背景

糖尿病会导致生物力学的改变，这可能会导致正常妊娠期间存在的生物力学改变。尚不清楚母体在受到糖尿病影响时的反应方式。本研究旨在描述 1 型糖尿病对孕妇姿势控制的影响。

 方法

40 名处于妊娠晚期的孕妇被分为两个相等的组：对照组和 1 型糖尿病组。使用摄影测量（测量头部前伸、颈椎前凸、胸椎后凸、腰椎前凸、骨盆前倾角、膝关节屈曲、胫跗骨和足部倾斜角度）和气压计（测量前后和中外侧距离轨迹）评估与姿势控制和平衡相关的变量。压力中心、振幅和压力中心位移的平均速度）。

 发现

姿势分析结果显示，1型糖尿病组的头前突和骨盆前倾角较低，而颈椎前凸、胸椎后凸和腰椎前凸角度较高。在压力足测量中，睁眼和闭眼时的前后距离和压力中心位移幅度较高。

 解释

研究结果表明，妊娠晚期的 1 型糖尿病与姿势改变、踝关节活动范围减少和压力中心前后摆动增加有关，对姿势控制产生负面影响。
