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.

Review Meta Analysis
The McKenzie method for low back pain: a systematic review of the literature with a meta-analysis approach.
Meta-analysis of randomized controlled trials to evaluate the effectiveness of the McKenzie method for low back pain (LBP). ⋯ There is some evidence that the McKenzie method is more effective than passive therapy for acute LBP; however, the magnitude of the difference suggests the absence of clinically worthwhile effects. There is limited evidence for the use of McKenzie method in chronic LBP. The effectiveness of classification-based McKenzie is yet to be established.

Review Meta Analysis
School-based interventions for spinal pain: a systematic review.
Systematic review. ⋯ The poor quality of the reviewed studies limits the conclusions that can be made regarding the effectiveness of school-based spinal health interventions.

Review Meta Analysis
Physical conditioning programs for workers with back and neck pain: a cochrane systematic review.
To determine the effect on time lost from work of physical conditioning programs for workers with back and neck pain. DATA SOURCES Randomized trials were located by searching MEDLINE, EMBASE, CINAHL, PsycINFO, the Cochrane Controlled Trial Register, and PEDro. ⋯ Physical conditioning programs that incorporate a cognitive-behavioral approach reduce the number of sick days for workers with chronic back pain when compared to usual care.

Review Meta Analysis Comparative Study
Muscle relaxants for nonspecific low back pain: a systematic review within the framework of the cochrane collaboration.
A systematic review of randomized and/or double-blinded controlled trials. ⋯ Muscle relaxants are effective in the management of nonspecific low back pain, but the adverse effects require that they be used with caution. Trials are needed that evaluate if muscle relaxants are more effective than analgesics or nonsteroidal anti-inflammatory drugs.
