Subjective disability is considered as the variable that reflects the impact of chronic pain on a patient's life. This study examines the questions of which syndrome or patient characteristics determine subjective disability and whether there are differences between samples of patients with chronic headaches and low back pain. Direct pain variables and depression, pain coping strategies, and pain-related self-statements (including catastrophizing) are introduced into multivariate regression analyses as potential predictors of disability using a sample of 151 pain patients. ⋯ In this study, we present a critical analysis of possible interpretations of our results. We point to an overlap of concepts underlying some of the variables used: this overlap also considerably invalidates conclusions drawn from a multitude of studies done in this field, including the one presented. We strongly argue for a conceptual clarification, and consequently for the revision of assessment instruments, before further empirical work in this area is done.

Chronic disability generates most of the costs associated with occupational low back pain, so the search for interventions that can reduce disability has been extensive. Outcome studies have been complicated by multiple study design and execution issues, as well as by the discrepancies between pain, impairment, and disability inherent in chronic pain populations. ⋯ These differences suggest strategies for improving our future approach to reducing disability from occupational low back pain. Overall, functional restoration programs administered by well-integrated, multidisciplinary staffs can be very effective in reducing disability from occupational low back pain.

Distributing educational material about low back pain to patients is increasingly seen as a possible adjunct to clinical management and a potential means of reducing the risk of the progression of the disorder toward chronic disability. Most back pain is managed in the primary care setting, where such material could save time and support the efforts of these practitioners. Recent evidence-based clinical guidelines for acute low back pain in U. ⋯ A new booklet has been developed which is evidence-based, in line with recent guidelines, and states its messages in a firm, uncluttered, and unambiguous manner. Preliminary studies show that it is readily accepted by patients, that they understand the messages, and that it creates a positive shift in beliefs about low back pain. Further studies regarding the use of this booklet are required to determine its effect on clinical outcomes.

Comparative Study
Sensory detection and pain thresholds in spinal cord injury patients with and without dysesthetic pain, and in chronic low back pain patients.
In an effort to understand the mechanisms involved in dysesthetic pain syndrome (DPS) in spinal cord injury (SCI) patients, four groups of 13 subjects each--SCI subjects with DPS, SCI subjects without pain, chronic low back pain subjects, and control subjects--were examined for sensory detection and pain thresholds at forearm, neck, and rostral trunk areas. Results indicated that the SCI pain group had significantly lower pain thresholds at all skin sites, compared to the SCI no-pain and chronic low back pain groups, and at the rostral trunk skin site, compared to the control group. ⋯ Equally important, the SCI no-pain group had detection and pain thresholds significantly higher than those of the control group. The results suggest fundamental differences in somatosensory processing when DPS is or is not a consequence of SCI.
