A quantitative biomechanical analysis of mechanism of pain alteration in 4 cases of low back pain. ⋯ Immediate pain reduction can be achieved by altering muscle-activation and movement patterns. However, the combination for optimal success seems to be different for every individual. Pain provocation tests help to "tune" the intervention. This also suggests that patient-classification schemes may need more refinement to address this heterogeneity.

Cross-sectional study. ⋯ Lower BMD is associated with a decreasing trend in both lumbar vertebral and disc volumes in elderly subjects but an increase in the Hm of the intervertebral discs.

A retrospective study of modic changes (MCs) in degenerative lumbar scoliosis (DLS). ⋯ The prevalence of MCs in patients with DLS was significantly higher than that of patients without DLS. Most of them were type 2 and usually located on the concave side of apex vertebrae. MCs were significantly associated with intervertebral disc degeneration and lumbar scoliosis.

Case-control study. ⋯ Adequate management of potential risk factors could help reduce the overall incidence of HO and outcome in patients with traumatic spinal cord injury.

In vivo large animal (pig) model study of cerebrospinal fluid (CSF) pressures after acute experimental spinal cord injury (SCI). ⋯ Although extradural compression exists at the site of injury, lumbar CSFP may not accurately indicate CSFP cranial to the injury. Decompression may provide immediate, though perhaps partial, resolution of the pressure differential. CSFPPA was not a consistent indicator of decompression in this animal model. These findings may have implications for the design of future clinical protocols in which CSFP is monitored after acute SCI.
