Comparative Study
Community studies of the health service implications of low back pain.
Retrospective study using primary care physician case notes and a self-report questionnaire on the same randomly selected population sample. ⋯ Prevalence rates were comparable with those reported in other studies. The significant discrepancies between data sources suggest patient recall bias or underrecording in case notes. The low consultation rate, time off, and day-to-day disability indicate that most episodes are self-limiting.

Back and neck pain was studied cross-sectionally in 1,449 urban transit drivers by linking medical data, self-reported ergonomic factors, and company records on job history. ⋯ The results support the hypothesis of a causal role of physical workload for the development of back and neck pain. Ergonomic factors partially mediated the risk of back and neck pain associated with driving, suggesting a potential for prevention of back and neck pain by ergonomic redesign of transit vehicles. Elevated risks for back and neck pain for female drivers were not explained by anthropometric and ergonomic factors.

Within the past decades, epidural steroid injections have been used in the treatment of severe low back pain and sciatica. In reviewing papers for this article an effort is made to concentrate on those that meet commonly accepted research design criteria, such as being blinded, randomized and prospective. The risks and the advantages of the procedure are discussed. ⋯ Risks of more serious complications are low using the right technique. However, the results are to some extent conflicting. Future correctly designed studies are necessary to clarify whether the injection should be a supplement to the established treatment of low back pain and sciatica.

To examine the impact of preinjury job perceptions on chronic pain patients (CPPs) return to work after pain facility treatment. ⋯ There is a relationship between preinjury job perceptions and actual return to work after pain facility treatment. Voiced "intent" not to return to the preinjury type of job is highly predictive of not returning to work after pain facility treatment.

Multicenter Study
Predictors of outcome in patients with chronic back pain and low-grade spondylolisthesis.
Retrospective case series. ⋯ This investigation, although limited by a number of factors including small sample size and retrospective, unblinded review, suggests that active worker's compensation and litigation issues are associated strongly with poor results of operative management for chronic low back pain in adult patients with low-grade spondylolisthesis.
