Impact of the flexibility of the spinal deformity on low back pain and disc degeneration in adult patients nonoperatively treated for adolescent idiopathic scoliosis with thoracolumbar or lumbar curves.

In AIS patients with TL/L curves, the flexibility of L4/5 disc wedging and the lumbar lateral ROM were significantly correlated with LBP and disc degeneration, independent of the magnitudes of the coronal deformities. Our findings indicate that maintaining or improving lumbar flexibility may be beneficial for preventing or treating LBP.
