Comparative Study
Concurrent validity of questionnaire and performance-based disability measurements in patients with chronic nonspecific low back pain.
This study aimed to investigate the concurrent validity of two approaches to disability measurement in patients with chronic nonspecific low back pain (CLBP). It was hypothesized that if both are measuring the same construct, the instruments would lead to similar disability results and would correlate strongly (r > 0.75). The study compared the results of self-reported and performance-based measures of disability in 64 consecutive patients with CLBP. ⋯ In contrast the results from the performance-based measures suggested that the subjects should be able to work at a physical intensity level of moderate to heavy. Little to moderate correlation was observed between the self-report and performance-based measures (Spearman rank correlations: Roland-FCE (-0.20), p > 0.05; Oswestry-FCE (-0.52), p < 0.01; Quebec-FCE (-0.50), p < 0.01). Results are interpreted to suggest that both performance-based and self-report measures of disability should be used in order to obtain a comprehensive picture of the disability in patients with CLBP.

Randomized Controlled Trial Clinical Trial
Treatment of chronic lower back pain with lumbar extension and whole-body vibration exercise: a randomized controlled trial.
A randomized controlled trial with a 6-month follow-up period was conducted. ⋯ The current data indicate that poor lumbar muscle force probably is not the exclusive cause of chronic lower back pain. Different types of exercise therapy tend to yield comparable results. Interestingly, well-controlled vibration may be the cure rather than the cause of lower back pain.

Randomized Controlled Trial Clinical Trial
Randomised study of long term outcome after epidural versus non-epidural analgesia during labour.
To determine whether epidural analgesia during labour is associated with long term backache. ⋯ After childbirth there are no differences in the incidence of long term low back pain, disability, or movement restriction between women who receive epidural pain relief and women who receive other forms of pain relief.

Individuals with low back pain were classified by cluster analysis of their responses to the Dallas Pain Questionnaire. These results enabled development of an alternative simple classification tool that yielded results close to those obtained by the cluster analysis. ⋯ The Dallas Pain Questionnaire discriminated between different groups of persons with low back pain. The proposed classification uses a short, simple practical tool to assess different levels of low back pain.

Review
Guidelines for the use of discography for the diagnosis of painful degenerative lumbar disc disease.
Discography has been used as a diagnostic test in the evaluation of patients with recalcitrant low-back pain. Recently, its usefulness has been questioned because of the occurrence of false-positive results as well as the influence of psychological factors on test results. The purpose of this review is to establish the literature support for and against the use of discography. A search of the English-language literature published between 1966 and 2001 was performed. Papers were selected based on inclusion criteria described in the text, and the quality of information was graded using previously described methods. ⋯ The authors propose a set of practice parameters based on the literature. Although the data were not judged adequate for the determination of a treatment standard, parameters for the use of discography are provided at a guideline and option level.
