Current development of civilization and technology makes a sitting position dominant in everyday life. This applies also to patients with spinal deformities.

The aim of this study was to analyze the size of physiological spinal curvatures in standing and sitting posture in girls with left lumbar scoliosis and evaluate usefulness of Zebris CMS-10 System in the assessment of physiological curvatures in both positions.

Material and methods:
A group of 30 girls aged 11–17 years with left lumbar idiopathic scoliosis, with a Cobb angle in the range of 10°–21°, was examined. Control group consisted of 30 healthy girls aged 10–17 years. Studies were conducted with the use of ZEBRIS CMS-10 System (Zebris Medical, Germany) in a standardized standing (P1) and sitting (P2) position. Mean kyphosis and lordosis angle and differences between kyphosis and lordosis angle dependent upon positional changes were analyzed in each of the groups.

Results and discussion:
Mean kyphosis angle in both positions showed no statistically significant differences between the study group and control group. Mean lordosis angle in P1 position in the study group was statistically significantly higher than in control group. Differences between mean kyphosis angle in P1 and P2 position in the study group in comparison with control group were not statistically significant. Differences between mean lordosis angle in P1 and P2 position in comparison with control group showed a statistical significance.

The presence of low degree lumbar scoliosis can result in deepening of lumbar lordosis in the standing posture, but it does not significantly affect kyphosis angle measured in standing and sitting position. Zebris CMS 10 System is a useful tool for the assessment of physiological spinal curvatures in standing and sitting position.
