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
Systematic correlation of transcranial magnetic stimulation and magnetic resonance imaging in cervical spondylotic myelopathy.
A prospective study over a 3.5-year period involving transcranial magnetic stimulation and magnetic resonance imaging. ⋯ Transcranial magnetic stimulation showed excellent correlation with magnetic resonance imaging findings and can be considered as an effective technique for screening patients for cervical cord abnormalities before magnetic resonance imaging in the clinical setting. The findings in this study have relevant implications in the pathophysiology, management, and health costs of cervical spondylotic myelopathy.
