Psychologic distress and low back pain. Evidence from a prospective study in the general population.
The present is a prospective population-based cohort study. ⋯ Symptoms of psychologic distress in individuals without back pain predict the subsequent onset of new episodes of low back pain. We calculate from these data that the proportion of new episodes of low back pain that might be attributable to such psychologic factors in the general population is 16%.

Comparative Study
Minnesota Multiphasic Personality Inventory profiles in persons with or without low back pain. A 20-year follow-up study.
A general health survey including a cross-sectional study of 404 men and women aged 50 years who underwent follow-up evaluation at ages 60 and 70 years. ⋯ Elevations of Minnesota Multiphasic Personality Inventory Hypochondriasis-Depression-Hysteria scales were shown in persons with a history of low pack pain. The results indicated that low back pain is preceded by elevated Minnesota Multiphasic Personality Inventory scales was not supported.

Comparative Study
The dominant role of psychosocial risk factors in the development of chronic low back pain disability.
An inception cohort design was used in which 421 patients were evaluated systematically with a standard battery of psychosocial assessment tests (Structured Interview for DSM-III-R Diagnosis, Minnesota Multiphasic Personality Inventory, and Million Visual Pain Analog Scale) within 6 weeks of acute back pain onset. ⋯ These results show the presence of a robust "psychosocial disability factor" that is associated with those injured workers who are likely to develop chronic low back pain disability problems. Based on these data, a statistical algorithm has been generated that can identify those acute patients who will require early intervention to prevent the development of chronic disability. The second major result is that preinjury or concomitant psychopathology does not appear to predispose patients to chronic pain disability, although high rates of psychopathology have been shown in chronic low back pain. Future research should be directed at emotional vulnerability and psychosocial events in the period after the injury that may lead to chronicity.

Meta Analysis
Efficacy of epidural steroid injections for low-back pain and sciatica: a systematic review of randomized clinical trials.
The purpose of the study was to assess the efficacy of epidural steroid injections for low-back pain. Data was obtained using computer-aided search of published randomized clinical trials and assessment of the methods of the studies. Twelve randomized clinical trials evaluating epidural steroid injections were identified. ⋯ The efficacy of epidural steroid injections has not been established. The benefits of epidural steroid injections, if any, seem to be of short duration only. Future research efforts are warranted, but more attention should be paid to the methods of the trials.
