Meta Analysis
Efficacy of epidural steroid injections for low-back pain and sciatica: a systematic review of randomized clinical trials.
The purpose of the study was to assess the efficacy of epidural steroid injections for low-back pain. Data was obtained using computer-aided search of published randomized clinical trials and assessment of the methods of the studies. Twelve randomized clinical trials evaluating epidural steroid injections were identified. ⋯ The efficacy of epidural steroid injections has not been established. The benefits of epidural steroid injections, if any, seem to be of short duration only. Future research efforts are warranted, but more attention should be paid to the methods of the trials.

We have reviewed 293 papers published since 1950 to assess the evidence of effect of ultrasound in the treatment of musculoskeletal disorders. Twenty-two clinical papers describing trials comparing ultrasound treatment with sham-ultrasound treated, non-ultrasound treatment and untreated groups were found. These papers were evaluated with respect to a list of criteria which should be met in this type of trial. ⋯ An analysis of the effect of proper randomisation on the result was not possible because of inadequate description of the methods used. We conclude that the use of ultrasound in treatment of musculoskeletal disorders is based on empirical experience, but is lacking firm evidence from well-designed controlled studies. One question remaining is whether ultrasound treatment can augment an effect of exercise therapy with respect to musculoskeletal disorders.

Meta Analysis Comparative Study
Efficacy of multidisciplinary pain treatment centers: a meta-analytic review.
Sixty-five studies that evaluated the efficacy of multidisciplinary treatments for chronic back pain were included in a meta-analysis. Within- and between-group effect sizes revealed that multidisciplinary treatments for chronic pain are superior to no treatment, waiting list, as well as single-discipline treatments such as medical treatment or physical therapy. ⋯ These results tend to support the efficacy of multidisciplinary pain treatment; however, these results must be interpreted cautiously as the quality of the study designs and study descriptions is marginal. Suggestions for improvement in research designs as well as appropriate reports of research completed are provided.
