Comparative Study Clinical Trial Controlled Clinical Trial
Prospective controlled study of the development of lower back pain in previously asymptomatic subjects undergoing experimental discography.
A prospective controlled longitudinal study. ⋯ Painful disc injections are poor independent predictors of subsequent LBP episodes in subjects initially without active lower back complaints. Anular disruption is a weak predictor of future LBP problems. Psychological distress and preexisting chronic pain processes are stronger predictors of LBP outcomes.

Randomized Controlled Trial Comparative Study Clinical Trial
Mini-intervention for subacute low back pain: two-year follow-up and modifiers of effectiveness.
Randomized controlled trial. ⋯ Mini-intervention is an effective treatment for subacute LBP. Despite lack of a significant effect on intensity of low back pain and perceived disability, mini-intervention, including proper recommendations and advice, according to the "active approach," is able to reduce LBP-related costs. The perceived risk of not recovering was the strongest modifier of treatment effect. In alleviating pain, the intervention was most effective among the patients with a high perceived risk of not recovering.

Comparative Study
Analgesic overuse among subjects with headache, neck, and low-back pain.
To examine the prevalence of chronic headache (> or =15 days/month) associated with analgesic overuse in relation to age and gender and the association between analgesic overuse and chronic pain (i.e., migraine, nonmigrainous headache, neck and low-back pain). ⋯ Chronic headache associated with analgesic overuse is prevalent and especially chronic migraine is more strongly associated with frequent intake of analgesics than other common pain conditions like chronic neck and chronic low-back pain.
