Relationship between self-reported low-back pain severity and other patient-reported outcomes: results from an observational study.
A cross-sectional observational study of physicians and patients with chronic low-back pain (CLBP) in the United States. ⋯ The association between patient-reported CLBP severity and other patient-reported outcomes demonstrates that in the clinical setting, patient-reported CLBP severity provides an accurate and suitable indicator of patient-reported health status. This indicator may be useful for guiding management strategies for CLBP patients.

Lumbar facet joint motion in patients with degenerative spondylolisthesis.
Controlled laboratory study. ⋯ The range of rotation decreased at the facet joints at the DLS level (L4-L5) in patients compared with those in healthy subjects and DDD patients. This decrease in range of rotation implies that the DLS disease may cause restabilization of the joint. The data may help the selection of conservative treatment or different surgical techniques for the DLS patients.
