Randomized Controlled Trial Multicenter Study Comparative Study
The MRC spine stabilization trial: surgical methods, outcomes, costs, and complications of surgical stabilization.
A review of the surgical costs and results in a group of patients randomly allocated to surgery as part of a large prospective randomized trial of patients with chronic back pain. ⋯ These observational changes in the ODI after surgery are similar to those reported from other studies of spinal fusion. More complex surgery is more expensive with more complications than postero-lateral fusion.

Comparative Study
Postural model of sagittal spino-pelvic alignment and its relevance for lumbosacral developmental spondylolisthesis.
Comparative study of sagittal spino-pelvic alignment in children and adolescents with developmental lumbosacral spondylolisthesis compared with asymptomatic subjects. ⋯ Children and adolescents stand with a relatively constant global sagittal spino-pelvic alignment, regardless of the local lumbosacral deformity. A normal posture is maintained in low-grade spondylolisthesis and in high-grade spondylolisthesis with a balanced sacro-pelvis. Posture is abnormal in high-grade spondylolisthesis associated with a retroverted sacro-pelvis, suggesting that surgical reduction of the local lumbosacral deformity in these patients could be attempted to restore a normal posture.

Multicenter Study Comparative Study
The use of traction in the treatment of severe spinal deformity.
Multicenter, retrospective, nonrandomized comparison group study of patients with severe scoliosis and kyphosis treated after 1995 with halo-gravity traction and without halo-gravity traction before definitive fusion. ⋯ Our study shows that patients with halo traction less frequently had a vertebral body resection, but achieved comparable deformity correction.

Systematic review. ⋯ There is insufficient evidence from RCTs to conclude that any 1 locomotor training strategy improves walking function more than another for people with SCI. Research in the form of large RCTs is needed to address specific questions about the type of locomotor training which might be most effective in improving walking function of people with SCI.

Cross-cultural adaptation and cross-sectional psychometric testing in a convenience sample of patients with low back pain. ⋯ The results of this study indicate that the Chinese version of the ODI 2.1 is a reliable and valid instrument for the measurement of functional status in patients with low back pain.
