“It is well established that osseoligamentous spine (bone and ligaments) is inherently unstable; that is, with out muscular support the spine – thoracic spine until sacrum (tail-bone), will buckle under the compression load of only 20N. Whereas the lumbar spine alone can support 90N of compression load.”

It is important to focus on strengthening the muscles that can provide dynamic stability (stability while we are in motion) and this would have a large role to play in effectively addressing low back pain.
