Objectives: To study postural and spinal static modifications associated with chronic low back pain in menopausal women.
Methods: Clinical appreciation of static spinal profile in sagittal plane; postural evaluation on the Balance Master Neurocom force platform by the modified clinical test for the sensory interaction on balance (modified CTSIB test); Radiological evaluation of spinal and pelvic parameters as well as the sagittal profile according to the Roussouly classification.
Results: Spinal curves clinical measurement and the sway velocity of the pressure center on the Balance Master Neurocom do not show significant difference between the two groups. While the pressure center position in the anteroposterior axis shows significant difference between the two groups (p=0.02) with a more backwards projection found in chronic low back pain subjects. Radiological evaluation shows sagittal shelter significantly superior, sacral slope significantly lower and the type 1 of lumbar lordosis more frequent in chronic low back pain women compared to healthy women.
Discussion-conclusion: In menopausal women, chronic low back pain seems to be associated with lower sacal slope, the type 1 of lumbar lordosis more frequent and behindly projection of pressure center.
