Multicenter Study Controlled Clinical Trial
Neuroprotective therapy using granulocyte colony-stimulating factor for patients with worsening symptoms of thoracic myelopathy: a multicenter prospective controlled trial.
An open-labeled multicenter prospective controlled clinical trial. ⋯ The results provide evidence that G-CSF administration caused neurological recovery in patients with worsening symptoms of thoracic compression myelopathy.
-
A cross-sectional, multicenter study. ⋯ Factors associated with a higher risk vary between LBP and PGP. History of LBP, related or not to previous pregnancy or postpartum, LBP surgery, and anxiety were the factors more strongly associated with pregnancy-related LBP. When these variables are taken into account, obstetrical data from current or previous pregnancies and other variables do not show a significant association with LBP. Stage of pregnancy and depression were associated with PGP.

Retrospective review of the data collected prospectively through the Spine Patient Outcomes Research Trial (SPORT). ⋯ These results illustrate important differences between racial groups in terms of response to spine care. Although there were quantitative differences between groups, these findings are not necessarily indications of health care disparities.

Multicenter Study
Effectiveness of 3 surgical decompression strategies for treatment of multilevel cervical myelopathy in 3 spinal centers in China: a retrospective study.
Retrospective multicenter study. ⋯ One-stage posterior-anterior strategy can be a reliable and effective treatment strategy for MCM in a subgroup of patients with anterior and posterior compression on spinal cord simultaneously.

Randomized Controlled Trial
Guiding low back claimants to work: a randomized controlled trial.
A single-blinded, randomized controlled trial. ⋯ Claimants should be routinely reassured and advised about LBP to allow early and safe RTW during a disability evaluation before any side effects of being sick-listed have settled.
