How can stretching help for back pain?

See below: In my experience, stretching has been one of the most consistently effective treatments for lower back pain although not everyone agrees with that statement. Our spines are meant to move and meant to be flexible. When we lose that flexibility, pain often follows.

Is stretching a cure: In my osteopathic manipulative pain practice, i actually find that in many cases, tight muscles are not the root cause of pain; they are a result of loose ligaments in the spine, sacral, & pelvic regions. Ligaments should prevent too much motion, but muscle should create motion. Loose ligaments can't do their jobs, so muscles tighten to do it for them. Prolotherapy is often better than stretching.
