Multicenter Study
Prognostic factors for reduction of activities of daily living following osteoporotic vertebral fractures.
Prospective cohort study. ⋯ These results identified presence of middle column injury of the vertebral body and lack of regular exercise before fracture as prognostic factors for reduced ADL. With clarification and validation, these risk factors may provide crucial tools for determining subsequent OVF treatments. Patients showing these prognostic factors should be observed carefully and treated with more intensive treatment options.

Multicenter Study
The association of patient characteristics and spinal curve parameters with Lenke classification types.
Retrospective review. ⋯ Lenke types vary by sex, frequency magnitude, patient age, and patient self-image, which should be considered in designing studies.

Randomized Controlled Trial
Effect of core stability exercises on feed-forward activation of deep abdominal muscles in chronic low back pain: a randomized controlled trial.
A randomized controlled trial. ⋯ Abdominal muscle onset was largely unaffected by 8 weeks of exercises in chronic LBP patients. There was no association between change in onset and LBP. Large individual variations in activation pattern of the deep abdominal muscles may justify exploration of differential effects in subgroups of LBP.

Longitudinal cohort. ⋯ Patients with lumbar degenerative disorders have health state values similar to patients with chronic renal disease, Crohn's disease, or coronary artery disease. Health state values of patients with different indications for surgery differ at baseline and after surgery. Revision cases have worse baseline SF-6D scores and less improvement in scores at 2 years after surgery than primary cases. Further studies are needed to gain a greater understanding of health state utility values in patients with lumbar degenerative disorders.

Comparative Study
Gender difference in association between low back pain and metabolic syndrome: locomotive syndrome and health outcome in Aizu cohort study (LOHAS).
Cross-sectional survey. OBJECTIVE.: To investigate the relationship between low back pain (LBP) and metabolic syndrome (Mets) in community-based Japanese subjects. SUMMARY OF BACKGROUND DATA.: Relatively few reports have demonstrated a relationship between general pain and Mets, and none have addressed the relationship between LBP and Mets. ⋯ We observed a tendency toward higher prevalence of Mets among those with LBP than among those without it in women, but not in men.
