Barré vertical axis examination is another way to perform a fast and uncomplicated postural scan. In the sagittal view, a plumb line is placed along the occipital, thoracic and gluteal prominences. In good posture these landmarks lie on the same vertical plumb line. In forward head position the occipital prominence will lie anterior to the Barré vertical axis, while in increased thoracic kyphosis, the thorax will lies posterior to the Barré vertical axis. In patient’s with an increased lumbar lordosis we will see that the thorax will lie anterior to the Barré vertical axis. In a sway back posture type all landmarks will lie on the Barré vertical axis, but the spinal curves are decreased and seem flattened.
