Randomized Controlled Trial Clinical Trial
Back extension endurance and strength: the effect of variable-angle roman chair exercise training.
A pre- and postintervention randomized, controlled trial was conducted. ⋯ Dynamic progressive resistance exercise training on a variable-angle Roman chair is capable of developing back extension endurance. Future research is needed to determine the clinical applicability of variable-angle Roman chair exercise training for patients with low back pain patients.

A 7-year prospective cohort study of 34,754 employed men and women was conducted. ⋯ In a broad public health perspective within a European welfare system, subjects at high risk for future back pain disability pension perceived their work as constantly physically demanding, had health complaints other than back pain, and mostly felt generally tired and worn out. The results indicate that interventions directed toward the painful back alone may be unsuccessful in preventing disability pensions.

A case-control association study and a stratified study investigating the genetic etiology for ossification of the posterior longitudinal ligament of the spine. ⋯ The contribution of genetic backgrounds is likely to be stronger in women than in men with ossification of the posterior longitudinal ligament of the spine. Estrogen receptor polymorphism was associated with both initiation and promotion of the disorder, but interleukin-1beta polymorphism was associated only with its initiation in women.

Individuals with low back pain were classified by cluster analysis of their responses to the Dallas Pain Questionnaire. These results enabled development of an alternative simple classification tool that yielded results close to those obtained by the cluster analysis. ⋯ The Dallas Pain Questionnaire discriminated between different groups of persons with low back pain. The proposed classification uses a short, simple practical tool to assess different levels of low back pain.

Case Reports
Severe erosion of lumbar vertebral body because of abdominal aortic false aneurysm: report of two cases.
Two cases of lumbar vertebral erosion resulting from abdominal aortic false aneurysm are reported. ⋯ In patients with endovascular prostheses, false aneurysm should be considered when lytic lesions of vertebral bodies are differentially diagnosed because these patients can present with only spinal symptoms.
