There is little evidence about posture influence and its relationship with pulmonary functions in chronic obstructive pulmonary diseases(COPD) patients.
To compare spinal curvature, mobility, and postural competency in participants with and without COPD and investigate the relationship of postural characteristics with dyspnea and pulmonary functions in COPD patients.
We included 47 COPD patients and 47 age and gender-matched controls in our cross-sectional study. Participants underwent the following evaluations: modified Medical Research Council Dyspnea Scale, respiratory function test, and postural measurements in the sagittal plane in a standing position using a non-invasive, computer-assisted electromechanical device. Postural variables were compared between groups, and the relationship between postural variables with dyspnea and pulmonary functions was analyzed by multivariate regression analysis.
Thoracic and lumbar curvature were higher (p<0.05), thoracic mobility and spinal inclination were lower (p=0.011, p=0.030, respectively) in patients with COPD. Thoracic angle and spinal inclination increased in COPD patients (p=0.040, p=0.011, respectively) while only spinal tilt increased in the control group (p=0.010) under spinal loading. Thoracic angle and mobility were related with dyspnea (r2=0.25, p<0.001), forced expiratory volume in the first second (r2=0.56, p<0.001), forced vital capacity (r2=0.41, p<0.001), and RV (r2 = 0.42, p<0.001).
COPD patients had greater thoracic and lumbar angles in the static upright posture and lower thoracic mobility and spinal inclination in the sagittal plane. It was observed that patients increase their thoracic angles to maintain postural stability in dynamic conditions. Thoracic angle and mobility were related to dyspnea and pulmonary functions.
关于姿势的影响及其与慢性阻塞性肺疾病（COPD）患者肺功能的关系，证据很少。
比较有和无 COPD 患者的脊柱曲率、活动度和姿势能力，并研究 COPD 患者的姿势特征与呼吸困难和肺功能的关系。
我们进行了一项横断面研究，纳入了 47 例 COPD 患者和 47 例年龄和性别匹配的对照组。参与者接受了以下评估：改良的医学研究理事会呼吸困难量表、呼吸功能测试和站立位时使用非侵入性、计算机辅助机电设备在矢状面进行的姿势测量。比较了两组之间的姿势变量，并通过多元回归分析分析了姿势变量与呼吸困难和肺功能的关系。
COPD 患者的胸腰曲率较高（p<0.05），胸腰椎活动度和脊柱倾斜度较低（p=0.011，p=0.030）。COPD 患者的胸角和脊柱倾斜度增加（p=0.040，p=0.011），而对照组仅在脊柱负荷下脊柱倾斜度增加（p=0.010）。胸角和活动度与呼吸困难（r2=0.25，p<0.001）、第一秒用力呼气量（r2=0.56，p<0.001）、用力肺活量（r2=0.41，p<0.001）和 RV（r2=0.42，p<0.001）相关。
COPD 患者在静态直立姿势下具有更大的胸腰角，在矢状面的胸腰椎活动度和脊柱倾斜度较低。在动态条件下，观察到患者增加胸角以维持姿势稳定性。胸角和活动度与呼吸困难和肺功能有关。
