The authors assessed the effectiveness of percutaneous pulsed radiofrequency treatment for providing pain relief in patients with chronic low-back pain with or without lower-limb pain. ⋯ The results of this prospective analysis showed that treatment with pulsed radiofrequency applied at the L-2 DRG is safe and effective for treating for chronic low-back pain. Satisfactory pain relief was obtained in the majority of patients in Group A with the effect persisting for at least 3 months. The results indicate that pulsed radiofrequency provided intermediate-term relief of low-back pain. Further studies with long-term follow-up are necessary.

Medical and non-medical direct costs of chronic low back pain in patients consulting primary care physicians in France.
A retrospective, observational, cohort study in primary care. To determine the total direct medical and non-medical cost of chronic low back pain (LBP) in France and its associated factors. Chronic LBP affects 5-10% of the population its burden in France is unknown. ⋯ Of these costs, 22.9% related to care provided by physiotherapists and allied specialists, 19.5% to medications, 17.4% to hospitalizations, 9.6% to investigations, and 12.5% to physician fees. In multivariate analysis, the factors associated with the cost of chronic LBP were disease severity (RMDQ score) and age of the patients. LBP is a disease that is both common and costly.

Workers in the United States with limited English proficiency likely perform more hazardous work, experience higher rates of work-related injury and illness, and have worse disability outcomes. ⋯ For those injured workers accessing the Washington State WC system, we observed differences based on language preference for pre-injury, and workers compensation outcomes. Further research is needed to explain the observed differences.

Randomized Controlled Trial
What factors influence the measurement properties of the Roland-Morris disability questionnaire?
Although the Roland disability questionnaire (RDQ) is a commonly used questionnaire for patients with low back pain (LBP), several important issues remain understudied. The purposes of this study were to investigate the impact that several parameters (length of test-retest interval, interpretation of the global perceived effect (GPE) scores, methods to estimate standard error of measurement (SEM), intervention and baseline scores) have on various measurement properties, such as agreement (Limits of Agreement (LOA), SEM(agreement)), responsiveness (area under the ROC curve, sensitivity, specificity) and interpretability (optimal cut-off point, Minimal Detectable Change), of the RDQ. RDQ was administered four times to 212 patients with chronic non-specific LBP (first consultation (T-1), eligibility check (T0), randomization/start of treatment (T1) and end of treatment (T2)). ⋯ Results revealed that agreement parameters decreased with increasing time interval between test-retest. They confirmed the influence of the interpretation of the GPE as well as of the method to calculate the SEM on the magnitude of the Minimal Detectable Change and ROC parameters. Baseline RDQ scores and the way to cluster patients with regard to baseline scores influenced mainly the optimal cut-off point and responsiveness parameters; intervention did not affect the magnitude of the Minimal Detectable Change.
