The aim of the study was to evaluate validity, reliability, responsiveness and practicality of the NASS-AAOS (North American Spine Society--American Academy of Orthopaedic Surgeons) questionnaire in patients with low back pain. ⋯ The instrument is valid, sensitive to clinical changes and reliable for comparisons between groups, but further study is needed for its application in monitoring individual patients.

Low back pain (LBP) is a common problem that poses some interesting and difficult diagnostic problems. It is typically benign and self-limited, but it is occasionally the presenting symptom of serious systemic disease. ⋯ In the absence of these features, imaging is of limited value. Recent research has begun to evaluate subgroups with 'non-specific' low back pain that seem to benefit from specific interventions such as median branch or sacroiliac joint injections, manipulation, or specific exercises, but these require further investigation and validation.

Review Comparative StudyTrend in methodological quality of randomised clinical trials in low back pain.
During the past decades, the number of published randomised clinical trials evaluating the efficacy of conservative treatments for low back pain has substantially increased. At the same time several initiatives were undertaken in order to improve the methodological quality of published randomised clinical trials, also in the field of low back pain. We investigated how the methodological quality of randomised clinical trials in the field of low back pain developed over time since the first published trial in 1961. ⋯ The median overall quality scores ranged from 36 to 82% depending on the type of intervention. There were no improvements in median overall methodological quality over time from 1960 to 2004. Improvements were apparent for a few validity criteria only.

Clinical Trial
Transforaminal lumbar interbody fusion: a safe technique with satisfactory three to five year results.
The unilateral transforaminal approach for lumbar interbody fusion as an alternative to the anterior (ALIF) and traditional posterior lumbar interbody fusion (PLIF) combined with pedicle screw instrumentation is gaining in popularity. At present, a prospective study using a standardized tool for outcome measurement after the transforaminal lumber interbody fusion (TLIF) with a follow-up of at least 3 years is not available in the current literature, although there have been reports on specific complications and cost efficiency. Therefore, a study of TLIF was undertaken. ⋯ At the latest follow-up, significant differences of the ODI were neither found between isthmic spondylolistheses and degenerative diseases, nor between one- and multiple-level fusions. In conclusion, the TLIF technique has comparable results to other interbody fusions, such as the PLIF and ALIF techniques. The potential advantages of the TLIF technique include avoidance of the anterior approach and reduction of the approach related posterior trauma to the spinal canal.

Comparative Study
Burden of illness of chronic low back pain in Sweden: a cross-sectional, retrospective study in primary care setting.
Cross-sectional survey of patients with chronic low back pain in primary care setting. ⋯ In Sweden, the indirect costs for chronic LBP appear to be substantially higher than the direct costs for pharmaceuticals, medical visits, physiotherapy, andhospitalizations. The high indirect costs indicate that more effective treatments for chronic LBP could potentially lead to cost savings even if the therapy costs were higher.
