Meta Analysis
Statistical significance versus clinical importance: trials on exercise therapy for chronic low back pain as example.
Critical appraisal of the literature. ⋯ It seems that many conclusions of studies of exercise therapy for chronic low back pain have been based on statistical significance of results rather than on clinical importance and, consequently, may have been too positive. Authors of trials should report not only statistical significance of results but also clinical importance.

Follow-up study. ⋯ Although in Spanish patients the influence of FAB on disability and quality of life is irrelevant, baseline FABQ score does influence LBP-related sick leave during the following year. This seems to be a direct effect of FAB, since there is no confounding by any other variable.

Anecdotal reports and limited data suggest that the use of spinal injections is increasing, despite equivocal evidence about efficacy. ⋯ Lumbosacral injections increased dramatically in the Medicare population from 1994 to 2001. Less than half were performed for sciatica or radiculopathy, where the greatest evidence of benefit is available. These findings suggest a lack of consensus regarding the indications for ESIs and are cause for concern given the large expenditures for these procedures.

A longitudinal assessment of the association between pain-related fear and joint motions in 36 participants with subacute low back pain. ⋯ Individuals with high pain-related fear adopt alternative movement strategies and avoid motion of the lumbar spine when performing a common reaching movement. Identifying how pain-related fear maps to actual motor behavior (i.e., alternative movement strategies) is a crucial first step in determining how pain-related fear and motor behavior interact to promote or delay recovery from acute low back pain.

Multicenter Study Clinical Trial
The LBP patient perception scale: a new predictor of LBP episode outcomes among primary care patients.
To describe a new tool designed to capture patients' perception of their low back pain (LBP) episodes-the patient perception scale (PPS) and test its ability to predict episode outcomes. ⋯ The PPS-pt could potentially be used as part of the standard initial patient evaluation of new LBP patients, as a proxy for "yellow flags" (markers of psychosocial risk) where a positive score might be the equivalent to high-risk identification. The apparent advantage of this scale is its brevity and simplicity of administration. The separation, through this scale of pain episodes into simple and complex LBP might be a useful tool for helping direct resources and avoiding chronicity.
