Randomized Controlled Trial Multicenter Study
Acupuncture for chronic low back pain in routine care: a multicenter observational study.
To investigate patient characteristics and outcomes after undergoing acupuncture treatment for chronic low back pain (cLBP) in Germany and to analyze chronification, pain grading, and depression as predictors for treatment outcomes. ⋯ Acupuncture treatment is associated with clinically relevant improvements in patients suffering from cLBP of varying degrees of chronification and/or severity.

The objective of the study was to assess inter-rater reliability of one palpation and six pain provocation tests for pain of sacroiliac origin. The sacroiliac joint (SIJ) is a potential source of low back and pelvic girdle pain. Diagnosis is made primarily by physical examination using palpation and pain provocation tests. ⋯ In conclusion this study has shown the reliability of the pain provocation tests employed were moderate to good, and for the palpation test, reliability was poor. Clusters out of three and five pain provocation tests were found to be reliable. The cluster of tests should now be validated for assessment of diagnostic power.

Caudal epidural injection for L4-5 versus L5-S1 disc prolapse: is there any difference in the outcome?
One hundred seventy-seven patients with radicular pain due to disc prolapse treated with caudal epidural injection were included in our study. All the injections were carried out between January 2000 and December 2004. Inclusion criteria include symptomatic disc prolapse diagnosed with magnetic resonance imaging scan, disc prolapse of 1 level only either L4-5 or L5-S1, leg pain for more than 4 wk and age more than 18. ⋯ The number of patients who required surgery were much less than the literature figures 3.05%. There is no significant difference in the response after caudal epidural injection considering the sex only. The longest the back pain before injection is associated with the worst Oswestry disability index.

Comparative Study Clinical Trial
Symptom profiles differ in patients with neuropathic versus non-neuropathic pain.
The distinction between neuropathic and non-neuropathic pain reflects partially distinct mechanisms and patterns of treatment response. It was therefore hypothesized that patients with neuropathic and non-neuropathic pain have different profiles of symptoms and signs. To test this hypothesis, pain intensity, unpleasantness, quality, and spatial characteristics were examined in 618 patients with 1 of 3 peripheral neuropathic pain conditions (painful diabetic peripheral neuropathy, painful idiopathic sensory polyneuropathy, or postherpetic neuralgia), osteoarthritis pain, or low back pain. These assessments were conducted before treatment had begun in clinical trials of lidocaine patch 5% administered alone or with stable dosages of other analgesics. Patients with osteoarthritis pain and low back pain did not differ in their profile of pain quality and spatial characteristics and were combined to form a group of patients with non-neuropathic pain. In univariate analyses, patients with peripheral neuropathic pain reported significantly more intense hot, cold, sensitive, itchy, and surface pain and significantly less intense dull and deep pain than patients with non-neuropathic pain. In a multivariate analysis, the overall pattern of pain quality and spatial characteristics differed significantly between patients with neuropathic and non-neuropathic pain. In addition, specific pain quality and spatial characteristics improved the discrimination of patients with neuropathic and non-neuropathic pain in a logistic regression model that adjusted for demographic covariates and overall pain intensity and unpleasantness. ⋯ The results indicate that the distinction between neuropathic and non-neuropathic pain is reflected in different profiles of pain quality and spatial characteristics and suggest that the assessment of patterns of pain symptoms might contribute to the identification of distinct pathophysiologic mechanisms and the development of mechanism-based treatment approaches.

Although the effect of physical workload on the occurrence of low back pain (LBP) has been extensively investigated, few quantitative studies have examined the morphological changes visualized via magnetic resonance imaging (MRI) in relation to occupational variables. The relationship between the severity of some abnormalities such as lumbar spinal stenosis or spondylolisthesis and physical or psychosocial occupational risk factors has not been investigated previously. In this cross-sectional study patients fulfilled the following inclusion criteria: (1) long-standing (minimum 1-year) LBP radiating down the leg (or not); (2) age more than 40 years; (3) willingness to undergo an MRI of the lumbar spine; and (4) ability to speak Italian. ⋯ A heavier job workload was the only occupational factor positively related to the degree of disability at the multivariate analysis (P=0.002). Total amount of degeneration in the lumbar spine directly influenced pain duration (P=0.011) and degree of disability (P=0.050). These results suggest that caution should be exercised when symptomatic subjects with evidence of degenerative changes on MRI scans engage in strenuous physical labor.
