Randomized Controlled Trial
Life dissatisfaction burden is associated with a poor surgical outcome among lumbar spinal stenosis patients: a 5-year follow-up study.
Dissatisfaction with life has been found to be associated with somatic health and the short-term surgery outcome in lumbar spinal stenosis (LSS) patients. This study investigated the effects of the long-term life dissatisfaction burden on the surgery outcome in LSS patients with a 5-year follow-up. This was a prospective clinical study. ⋯ In linear regression, the long-term life dissatisfaction burden was associated with the 5-year ODI, even after adjusting for age, sex, marital status, preoperative ODI and the 5-year VAS. It was not associated with the 5-year VAS score. Monitoring the life satisfaction of surgically treated LSS patients may enable detection of those at risk of a poorer surgery outcome.

Review Meta Analysis Comparative Study
Lumbar fusion compared with conservative treatment in patients with chronic low back pain: a meta-analysis.
We assess the effect of lumbar fusion (LF) in reducing disability among patients with chronic low back pain (CLBP) compared with conservative treatment and to weigh the clinical significance of this effect. We conducted a random-effect meta-analysis on the basis of a systematic review with research quality grading according to Grading of Recommendations Assessment, Development and Evaluation (GRADE). The studies included were retrieved from MEDLINE and Cochrane CENTRAL databases from 1990 till January 2013. ⋯ Test for heterogeneity indicated that study imputation would favor LF but the imputed result would still be clinically insignificant with an estimated corrected reduction of ODI score of -5.51 (95% confidence interval -5.78 to -5.24). There is strong evidence that LF is not more effective than conservative treatment in reducing perceived disability because of CLBP among patients with degenerative spinal diseases. It is unlikely that further research on the subject would considerably affect this conclusion.

Comparative Study
Measuring functional health among the elderly: development of the Japanese version of the World Health Organization Disability Assessment Schedule II.
The Japanese version of the World Health Organization Disability Assessment Schedule II (WHODAS II-J) was developed and its psychometric properties were evaluated, and then used to determine the influence of disability on quality of life among the elderly in Japan. The study included three phases: qualitative, preliminary and field. For the qualitative portion of the study, six key informants were interviewed before the translation/back-translation procedure. ⋯ A significant correlation was observed between the results of the WHODAS II-J and the degree of disability (P<0.01), and a negative correlation was observed between WHOQOL-BREF and WHODAS II-J scores (P<0.01). A significant difference was found between healthy elderly individuals and those with disabilities in three domains: getting around, self-care, and life activities (P<0.01). In conclusion, the WHODAS II-J is a reliable and valid instrument for assessment of function in the elderly population in Japan.
