Comparative Study
Centralization: its prognostic value in patients with referred symptoms and sciatica.
Prospective, comparative cohort study. ⋯ Patients with sciatica and suspected disc herniation who have a centralization response to a mechanical evaluation will have significantly better outcomes. Patients who do not have centralization will be 6 times more likely to undergo surgery.

Quasi-experimental, nonrandomized, nonequivalent, parallel group-controlled study involving before and after telephone surveys of the general population. ⋯ Significant sustained improvements in population beliefs about back pain were observed 3 years after cessation of a media campaign of provision of positive messages about back pain. This result provides further evidence that a primary preventive strategy of altering population beliefs about back pain may be a highly effective way for reducing back-related disability.

Cohort study of patients with low back pain (LBP) receiving physical therapy. ⋯ Clinicians can be confident that a 2-point change on the NPRS represents clinically meaningful change that exceeds the bounds of measurement error.
