PainSci summary of Ettinger 1994?This page is one of thousands in the PainScience.com bibliography. It is not a general article: it is focused on a single scientific paper, and it may provide only just enough context for the summary to make sense. Links to other papers and more general information are provided at the bottom of the page, as often as possible. ★★★☆☆?3-star ratings are for typical studies with no more (or less) than the usual common problems. Ratings are a highly subjective opinion, and subject to revision at any time. If you think this paper has been incorrectly rated, please let me know.

Posture is widely assumed to be a cause of pain, especially back pain, but even one of the most classic poor postures — kyphosis, excessive upper back curvature, “hunching over” — doesn’t seem to cause any trouble. In this study of 600 older women, not even the 10% with the worst kyphosis had “substantial chronic back pain, disability, or poor health.”

original abstract

To test the hypothesis that thoracic kyphosis is associated with substantial pain, disability, and height loss, we measured thoracic curvature, using an architect's flexicurve, of 610 women aged 65-91 years who were recruited from population-based listings. We assessed study subjects for back pain, back-related disability, height loss since age 25 years, perceived state of health, and bone mineral density (BMD) at the spine, calcaneus, proximal radius, and distal radius. Compared with the rest of the cohort, the 10% of women with the most severe kyphosis had 7%-17% lower BMD (p < 0.001) and had lost an additional 2.4 cm height (p < 0.001). However, kyphotic women had no greater back pain, disability caused by back problems, or poorer health. This cross-sectional study suggests that kyphosis is associated with decreased BMD and loss of height but does not cause substantial chronic back pain, disability, or poor health in older women.
