The significance of radiometry in examination of flexibility referring to part lumbo-sacralis of the vertebral column in cases of chronic low back pain.

A drop in flexibility of the vertebral column is connected with chronic low back pain. Qualification of vertebral column flexibility is not so simple. Beside of clinical methods (for example Schober test), we can use a radiological method. Comparing values of Whitman-Fergusson's angle and Cobb's angle for standing and supine-lying position, author has stated a significant drop in elastic properties of the vertebral column in patients with chronic low back pain.
