Abstract
BACKGROUND
There is little evidence about posture influence and its relationship with pulmonary functions in chronic obstructive pulmonary diseases(COPD) patients.
OBJECTIVES
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.
METHODS
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.
RESULTS
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).
CONCLUSION
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.
