Randomized Controlled Trial
Early rehabilitation targeting cognition, behavior, and motor function after lumbar fusion: a randomized controlled trial.
Open label randomized controlled trial with 3-, 6-, 12-month, and 2- to 3-year follow-up. ⋯ The study shows that postoperative rehabilitation can be safely implemented during the first 3 months after lumbar fusion and should include measures to modify psychological as well as motor functions.

Prospective study of community-based female volunteers. ⋯ This was the first study to confirm the relationship of PI and the development of DS in a long-term prospective observation. Proposed pathogenetic differences might explain the fact that L4-DS is far more prevalent than L3-DS. The development of DS could be predicted by baseline lumbopelvic morphology among the highly susceptible perimenopause women.

Comparative Study
The relationship between magnetic resonance imaging and quantitative electromyography findings in patients with compressive cervical myelopathy.
A retrospective comparison of magnetic resonance imaging (MRI) and quantitative electromyography (EMG) findings in patients with compressive cervical myelopathy (CCM). ⋯ Quantitative analysis of mean duration of MUPs provides a reliable indicator of physiologic disorder of spinal motor neurons in CCM and may contribute to establishing the site of motor neuron compromise in cases with multilevel spinal canal stenosis.

Retrospective case-referent study. ⋯ A positive sedimentation sign exclusively and reliably occurs in patients with LSS, suggesting its usefulness in clinical practice. Future accuracy studies will address its sensitivity and specificity. If they confirm the sign's high specificity, a positive sedimentation sign can rule in LSS, and, with a high sensitivity, a negative sedimentation sign can rule out LSS.

In vivo measurement of lumbar facet joint surface area. ⋯ The lumbar facet areas measured in vivo in this study were similar to previous cadaveric studies. The lumbar facet area was significantly greater at the inferior lumbar levels and also increased with age. This age-related increase in the facet joint surface was observed more in the low back pain subjects compared with asymptomatic subjects. The increase in the area of the facet joint surface is probably secondary to increased load-bearing in the lower lumbar segments and facet joint osteoarthritis.
