Central processing of acute muscle pain in chronic low back pain patients: an EEG mapping study.
The presence of perceptual sensitization and related brain responses was examined in 14 chronic low back pain (CLBP) patients and 13 healthy controls comparable in age and sex. Multichannel EEG recordings and pain ratings were obtained during the presentation of 800 painful electrical intramuscular and intracutaneous stimuli each to the left m. erector spinae and the left m. extensor digitorum. Perception and pain thresholds were not significantly different between the two groups, though patients showed significantly more perceptual sensitization. ⋯ These results indicate enhanced perceptual sensitization and enhanced processing of the sensory-discriminative aspect of pain, as expressed in the N80 component, in CLBP patients. This may be one neurophysiologic basis of sensitization and the chronicity process. The lower P260 component in the patients may be explained in terms of tonic pain inhibiting phasic pain or may be related to the affective distress observed in this patient group.

Review Meta Analysis
Systematic review: opioid treatment for chronic back pain: prevalence, efficacy, and association with addiction.
The prevalence, efficacy, and risk for addiction for persons receiving opioids for chronic back pain are unclear. ⋯ Opioids are commonly prescribed for chronic back pain and may be efficacious for short-term pain relief. Long-term efficacy (> or =16 weeks) is unclear. Substance use disorders are common in patients taking opioids for back pain, and aberrant medication-taking behaviors occur in up to 24% of cases.

Systematic review of randomized controlled trials. ⋯ In the long-term, multidisciplinary back training has a positive effect on work participation in patients with nonspecific chronic low back pain.

A population-based, prospective cohort. ⋯ Emotional distress is a predictor for low back disability in persons with earlier LBP, but not in persons without. To prevent low back disability, emotional distress should be considered and treated in persons with LBP.
