[Lumbago and work: contribution of rehabilitation. State of the art].

In the treatment of chronic low back pain the efficacy and specificity of rehabilitation has been scientifically demonstrated, as testified by the actual International Clinical Guidelines. The usable techniques include Back School and functional rehabilitation: the first one relate patients with low functional impairments, and usually no working disability, while the second one should be used when there is a disability in the activity of daily living and in the profession. Even if originally developed as an inpatient treatment, in these years some randomised controlled trials have shown the efficacy also of outpatient techniques for functional rehabilitation, as the DBC proposal.
