目的：研究怀孕过程中坐姿和站立姿势以及产后期间上身在矢状面的姿势对齐情况。设计：纵向、重复测量设计。地点：澳大利亚大学生物力学实验室。参与者：志愿者方便样本，其中 9 名初产妇和多产妇以及 12 名未产妇作为对照组。干预措施： 不适用。主要结果指标：在整个怀孕期间和产后 8 周时，每隔一段时间对受试者坐着和安静站立时进行拍摄。使用重复测量方差分析来评估骨盆、胸椎和头部以及胸腰椎和颈胸椎对齐的系统变化。使用学生 t 检验来比较产后对照组和未产妇对照组。结果：妊娠对上半身姿势没有显着影响，尽管随着妊娠的进展，某些受试者在坐姿时胸腰椎曲线有趋于平坦的趋势。产后站立时，骨盆段矢状面前倾减少，胸腰椎伸展较少，表明与对照组相比脊柱曲线更平坦。结论：妊娠对坐姿和站立时上半身姿势没有显着影响，尽管个体的姿势反应存在差异。产后站立时发现脊柱曲线更平坦。 (C) 2002 年由美国康复医学大会和美国物理医学与康复学会颁发。
Objective: To investigate the postural alignment of the upper body in the sagittal plane during sitting and standing postures as pregnancy progressed and then in the postpartum period.Design: Longitudinal, repeated-measures design.Setting: Biomechanics laboratory in an Australian university.Participants: A volunteer convenience sample of 9 primiparous and multiparous women and 12 nulliparous women serving as a control group.Interventions: Not applicable.Main Outcome Measures: Subjects were filmed while sitting and during quiet standing at intervals throughout pregnancy and at 8 weeks postpartum. A repeated-measures analysis of variance was used to assess systematic changes in the alignment of the pelvic, thoracic, and head segments, and the thoracolumbar and cervicothoracic spines. Student t tests were used to compare the postpartum and nulliparous control groups.Results: There was no significant effect of pregnancy on the upper-body posture, although there was a tendency in some subjects for a flatter thoracolumbar spinal curve in sitting as pregnancy progressed. Postpartum during standing, the pelvic segment had a reduced sagittal plane anterior orientation, and the thoracolumbar spine was less extended, indicating a flatter spinal curve compared with the control group.Conclusions: There was no significant effect of pregnancy on upper-body posture during sitting and standing, although individuals varied in their postural response. A flatter spinal curve was found during standing postpartum. (C) 2002 by the American Congress of Rehabilitation Medicine and the American Academy of Physical Medicine and Rehabilitation.
