Randomized Controlled Trial Comparative Study
One-year follow-up in employees sick-listed because of low back pain: randomized clinical trial comparing multidisciplinary and brief intervention.
Randomized clinical trial comparing two interventions in employees sick-listed 3 to 16 weeks because of low back pain (LBP). ⋯ Hospital-based multidisciplinary intervention may be no better than brief intervention to increase RTW and improve health in sick-listed employees with low back pain.

Randomized Controlled Trial
Posterior multilevel vertebral osteotomy for severe and rigid idiopathic and nonidiopathic kyphoscoliosis: a further experience with minimum two-year follow-up.
Prospective randomized study. ⋯ PMVO exhibited satisfactory clinical and radiologic results in patients with severe and rigid scoliosis associated with hyperkyphosis at minimum 2-year follow-up. It can be safely applied with modifications in original technique for complex congenital scoliosis with multilevel hemi or block vertebrae and idiopathic/nonidiopathic spinal deformities.

Randomized Controlled Trial Multicenter Study Comparative Study
Sagittal alignment after Bryan cervical arthroplasty.
Prospective, randomized, Food and Drug Administration Investigational Device Exemption trial from one study site. ⋯ With the Bryan disc, there was an insignificant increase in lordosis of 0.9° at immediate postoperative time point. Overall cervical sagittal alignment is not different between the experimental and control populations. This prospective study does not demonstrate a clinically significant increase in segmental kyphosis after Bryan disc arthroplasty. Global cervical lordosis is statistically equivalent between arthroplasty and fusion groups at 2 years follow-up.

Randomized Controlled Trial Multicenter Study Comparative Study
Differences in the relationship between psychosocial distress and self-reported disability in patients with chronic low back pain in six pain rehabilitation centers in the Netherlands.
A cross sectional multicenter study in six outpatient Rehabilitation Centers (RCs) in the Netherlands. ⋯ The overall relationship between psychosocial distress and self reported disability was weak, and differences between RCs were considerable. This indicates that the relationship between psychosocial distress and disability in patients with CLBP is not uniform.

Randomized Controlled Trial Comparative Study
Diagnostic accuracy of the clinical examination in identifying the level of herniation in patients with sciatica.
Cross sectional ⋯ The current study did not find evidence to support the accuracy of individual tests from the neurological examination in identifying the level of disc herniation demonstrated on MRI. A neurologist's overall impression was moderately accurate in identifying the level of disc herniation.
