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.

The lumbar sacropelvis in 11 patients with myelomeningocele and kyphosis was treated with a subtraction kyphectomy technique and posterior instrumentation. The results of this procedure in the 11 patients were evaluated and compared with previous results. ⋯ The subtraction (decancellation) vertebrectomy technique with preservation of the dural sac is a safe and efficacious technique for correction and stabilization of myelomeningocele kyphosis in young patients. Morbidity is reduced, as compared with that of excision techniques. Restoration of sagittal alignment at the time of initial correction and stabilization to achieve a balanced spine led to acceptable results.

Economic evaluation provides a framework to explicitly measure and compare the value of alternative medical interventions in terms of their clinical, health-related quality-of-life, and economic outcomes. Computerized economic models can help inform the design of future prospective studies by identifying the cost-drivers, the most uncertain parameter estimates, and the parameters with the greatest impact on the results and inferences. ⋯ Future research should focus on quantifying the health-related quality-of-life impact of bone morphogenetic protein relative to autogenous iliac crest bone graft, as well as the impact on lost productivity.

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.
