Rasch analysis of an outcome tool using data from questionnaires completed by patients with lumbar spinal stenosis. ⋯ Development of a more robust measurement tool for this patient group may be warranted. A new tool may need to include three scales to measure the separate domains of pain severity, neuroischemic symptom severity, and physical function.
-
A cross-sectional imaging study of young adults. ⋯ Low back symptoms and functional limitations over a 3-year period were not associated with increased fat content or a reduction in the cross-sectional area of lumbar paraspinal muscles among young adults.
-
A prospective, randomized laboratory investigation. ⋯ The results indicated that minocycline administration improved hind-limb motor function and attenuated gray and white matter injury and microglial activation after spinal cord ischemia in rats.
-
Retrospective chart review. ⋯ This study suggests that plain radiographs should be performed as indicated clinically rather than routinely after instrumented lumbar fusion. The vast majority of asymptomatic patients do not require routine postoperative radiographs.
