Download this research article that used the dorsaVi Low Back module to assess patients with Idiopathic Adolescent Scoliosis. Lack of lumbar lordosis is a postural abnormality that has been identified as a pathologic posture in degenerative scoliosis. This pathologic posture is promoted by several biomechanical factors, most notably spinal flexion and pelvic retroversion. Loss of lumbar lordosis leaves the spine vulnerable to more shear forces, increasing the risk for rotational deformities.
