Spinal Posture Assessment In Health Exams Reliably Detects Cognitive Decline
A mass survey of citizens aged 50 to 89 years examined whether cognitive decline could be detected by sagittal spinal balance measurement based on a radiological approach. Doctors from Shinshu University observed associations between sagittal vertical axis (SVA) anteriorization and higher age with lower cognitive function. The sagittal vertical axis is the length of a horizontal line connecting the posterior superior sacral end plate to a vertical plumbline dropped from the centroid of the C7 vertebral body (Photo 1). The more the head and neck protrude in front of the pelvis when viewed from the side, (the greater the length) the more likely subjects are to show symptoms of mild cognitive decline. In males, the SVA was associated with cognitive decline independently of age. In females, cognitive decline was more likely in cases of SVA that is equal to or greater than 70mm regardless of age.
