Review Comparative Study
Fear of movement/(re)injury, avoidance and pain disability in chronic low back pain patients.
Chronic pain syndromes such as chronic low back pain are responsible for enormous costs for health care and society. For these conditions a pure biomedical approach often proves insufficient. ⋯ The main assumption is that pain and pain disability are not only influenced by organic pathology, if found, but also by psychological and social factors. In this contribution, a behavioural analysis of chronic musculoskeletal pain will be discussed, with special attention to the role of pain-related fear in the development and maintenance of chronic pain disability, and the behavioural rehabilitation perspective of chronic pain management.

Randomized Controlled Trial Clinical Trial
Endurance training of the trunk extensor muscles in people with subacute low back pain.
Clinicians treating patients with low back pain often use exercise to reduce pain and improve function. The aim of this study was to evaluate the effectiveness of trunk extensor endurance training in reducing pain and decreasing disability in subjects with subacute low back pain (ie, onset of back pain within 7 days to 7 weeks). ⋯ Trunk extensor endurance training reduced pain and improved function at 3 weeks but resulted in no improvement at 6 weeks when compared with the control group. Endurance exercise is considered to expedite the recovery process for patients with an acute episode of low back pain.

A prospective analysis of the relative influence of pain-specific and performance-specific cognitive variables on lifting tasks using empirically derived measures. ⋯ Data suggest that what patients believed they could achieve accurately determined their actual spinal function, independent of their sense of control over pain or their distress. Approaches to low back disorders emphasizing perceived pain control as a central cognitive determinant of disability were unsupported.

Comparative Study
The association of the SF-36 health status survey with 1-year socioeconomic outcomes in a chronically disabled spinal disorder population.
The Short Form Health Survey (SF-36) was administered to patients with chronic spinal disorders both before and after tertiary rehabilitation. The association of the SF-36 with various socioeconomic outcomes was then examined. ⋯ The large number of associations between SF-36 scores and outcome variables highlights the importance of assessing the health-related quality of life of patients, and supports the use of the SF-36 in accomplishing this task. Among the findings, perhaps the most significant was the value of assessing health-related quality of life, particularly the subjective physical components, after completion of a functional restoration program. Prediction of long-term socioeconomic outcomes is likely to be improved if assessment is conducted at the end of the treatment process. SF-36 is recommended for assessing general health status, and more spine-specific measures are recommended for assessing spinal pain and disability variables.

This prospective study was designed to determine the prevalence of lumbar facet joint pain in a consecutive series of patients with chronic low back pain treated at an interventional, multidisciplinary private pain management practice utilizing double diagnostic blocks, to determine the prevalence of false positive rate of uncontrolled facet joint blocks, and to determine the relationship of clinical features of responders and non-responders to double diagnostic blocks. One hundred and twenty patients with low back pain with or without lower extremity pain were selected. The procedure consisted of diagnostic blocks using lidocaine and bupivacaine on separate occasions, usually two weeks apart. ⋯ However, history of previous surgery showed a negative correlation as only 29% of the patients after previous surgery were positive in contrast to 51% of the nonsurgical population. The results of this study echo previous concerns of reliability of uncontrolled single blocks, history, and clinical features. This study demonstrated that the facet joint is a source of pain in 45% of the patients suffering with chronic low back pain in an interventional pain management setting in a private practice.
