Chronic lower back pain (CLBP), without definable cause, is a symptom commonly presented to GPs, accounting for a significant proportion of their workload; it is also a common reason for sickness absence, and thus of national economic importance. ⋯ Presenting with CLBP permits the patient a good deal of power over the GP: it is difficult for the GP to challenge the patient's ideas without damaging the relationship. GPs are forced to collude with the patient's definition of ill-health, which may not be in the best interests of the patient or society.

Is epidural anesthesia in labor associated with chronic low back pain? A prospective cohort study.
The association between epidural anesthesia during labor and subsequent postpartum low back pain remains unclear. The objective of this follow-up cohort study was to determine whether epidural anesthesia was associated with chronic back pain 1 yr after delivery. We contacted 329 women by telephone and asked them to complete a standardized questionnaire 1 yr (+/-1 mo) after delivery. One hundred sixty-four women had received epidural analgesia for labor and delivery, and 165 had not. Subjects were asked to quantify their back pain (yes/no, numeric rating score, and interference with daily activities). Differences between the two groups were tested by using the chi2 test and the Mann-Whitney U-test, and logistic regression was used to control for confounding variables. The response rate was 244 of 329 (74%). Responders and nonresponders were similar in their demographic and clinical characteristics. There was no difference in the prevalence of back pain between women who had received epidural anesthesia (12 of 121, 10%) and those who had not (17 of 123, 14%). The adjusted relative risk of low back pain at 1 yr (epidural versus nonepidural) was 0.63 (95% confidence interval 0.25, 1.56). There were also no differences between the two groups on numeric rating scores or level of interference with activities. This prospective follow-up study demonstrated no association between epidural anesthesia for labor and delivery and chronic back pain 1 yr after delivery. ⋯ We evaluated the presence of low back pain 1 yr after delivery in two groups of women-those who chose epidural analgesia for labor and those who did not. There was no increased risk of back pain in women who had used epidural analgesia. This finding is consistent with those of other North American studies.

Low back pain is, in large part, a subjective illness. Clinicians must use patient descriptions of the severity and location of low back pain and how it responds to various activities and positions to make diagnostic and treatment decisions. Therefore, it is important to understand how reliably patients describe these aspects of low back pain. ⋯ Reliability of each item on the pain response to activity and position questionnaire was examined by calculating an unweighted Cohen's kappa. Overall, the three pain measures demonstrated fair to good test-retest reliability: 1) visual analogue scale = .66-.93, 2) pain drawing = .58-.94, and 3) pain response to activity and position questionnaire = .46-.89. The results of this study suggest that, although there is some variability in how consistently patients report various aspects of low back pain, the reliability of these pain measures is sufficient to permit their use in making clinical decisions and measuring treatment outcomes.

Efforts to examine the process and risk of developing chronic back pain have relied generally upon retrospective study of individuals with already established pain. In an alternative approach to understanding the clinical course and evolution of low back disorders, a cohort of 76 men experiencing their first episode of back pain was assessed prospectively at 2, 6 and 12 months following pain onset. Standard measures of pain (Descriptor Differential Scale: DDS), disability (Sickness Impact Profile: SIP), and distress (Beck Depression Inventory: BDI) were employed to classify the sample into five groups: Resolved, Pain Only, Disability/Distress Only, Pain and Mild Disability/Distress, and Clinical Range. ⋯ Comparison of those classified as 'improvers' with those who did not improve from 2 to 12 months showed similar findings. The clinical course of first onset back pain may be prolonged for many patients, and involves a continuum of related disability and distress. Individuals at risk for marked symptoms 1 year after an initial episode of back pain can be identified early, and prompt treatment might reduce the risk of pain chronicity.

Case ReportsManipulation under epidural anesthesia with corticosteroid injection: two case reports.
To discuss the combined use of selective epidural steroid injection (ESI) and spinal manipulative therapy (SMT) in treating recalcitrant lumbar radiculopathy. ⋯ This article discusses an integrated procedure that combines two standard treatments that may act synergistically. Our positive results are consistent with other reports, both published and anecdotal. The technique of MUEA warrants further investigation by the health care industry.
