Meta AnalysisEfficacy of spinal manipulative therapy for low back pain of less than three months' duration.
To review the efficacy of spinal manipulation for low back pain of less than 3 months duration. Data sources Randomized clinical trials on spinal manipulative therapy for low back pain were identified by searching EMBASE, CINAHL, MEDLINE, and the Physiotherapy Evidence Database (PEDro). Study selection Outcome measures of interest were pain, return to work, adverse events, disability, quality of life, and patient satisfaction with therapy. Data extraction Methodological assessment of the trials was performed using the PEDro scale. Trials were grouped according to the type of intervention, outcome measures, and follow-up time. Where there were multiple studies with sufficient homogeneity of interventions, subjects, and outcomes, the results were analyzed in a meta-analysis using a random effects model. Data synthesis Thirty-four papers (27 trials) met the inclusion criteria. Three small studies showed spinal manipulative therapy produces better outcomes than placebo therapy or no treatment for nonspecific low back pain of less than 3 months duration. The effects are, however, small. The findings of individual studies suggest that spinal manipulative therapy also seems to be more effective than massage and short wave therapy. It is not clear if spinal manipulative therapy is more effective than exercise, usual physiotherapy, or medical care in the first 4 weeks of treatment. ⋯ Spinal manipulative therapy produces slightly better outcomes than placebo therapy, no treatment, massage, and short wave therapy for nonspecific low back pain of less than 3 months duration. Spinal manipulative therapy, exercise, usual physiotherapy, and medical care appear to produce similar outcomes in the first 4 weeks of treatment.

Comparative Study
Presurgical biopsychosocial variables predict medical and compensation costs of lumbar fusion in Utah workers' compensation patients.
Elective lumbar fusion surgery is a prevalent and costly procedure that requires a lengthy rehabilitation. It is important to identify presurgical biopsychosocial predictors of medical and compensation costs in such patients. ⋯ Compensation and medical costs associated with posterolateral lumbar fusion can be predicted by preintervention biopsychosocial variables. Cost reduction programs might benefit from identifying biopsychosocial factors related to increased costs.

Attitudes and beliefs, or the treatment orientation, of health care providers appear to be important in the management of non-specific chronic low back pain (CLBP). The aims of the current study were two-fold: First of all, the physiotherapists' opinion towards various aspects of the management of CLBP was surveyed. Secondly, in a principal factor analysis, it was investigated whether underlying dimensions could be identified in order to develop the Pain Attitudes and Beliefs Scale for Physiotherapists (PABS_PT). ⋯ Biomedical specialists scored statistically significantly higher on the 'biomedical orientation' factor. Furthermore, the findings suggested that the PABS_PT discriminates between physiotherapists with a 'behavioural orientation' vs those with a 'biomedical orientation'. To examine the influence of these different treatment orientations with regard to CLBP on patient outcome is a challenge for the near future.

Randomized Controlled Trial Clinical TrialA pilot investigation of the hypoalgesic effects of transcutaneous electrical nerve stimulation upon low back pain in people with multiple sclerosis.
To investigate the hypoalgesic effects of transcutaneous electrical nerve stimulation (TENS) upon low back pain (LBP) in people with multiple sclerosis (MS). ⋯ Active TENS was more effective than placebo TENS in decreasing VAS scores following each treatment although results were not statistically significant. Further work in this area is warranted and should include a larger number of participants in the form of a randomized controlled clinical trial to determine the efficacy of this modality.

Randomized Controlled Trial Clinical Trial
The effect of opioid analgesia on exercise test performance in chronic low back pain.
The effect of opioid analgesia on tests of muscular function in chronic low back pain (CLBP) is unknown. Twenty-eight subjects with CLBP of at least moderate intensity performed the Sorensen isokinetic exercise test once after receiving 1 microg/kg fentanyl intravenously and once after placebo in a randomized-order double-blind crossover design. Naloxone 3 microg/kg was administered after the fentanyl phase. ⋯ We presume that the pain relief resulted in increased test performance. Our result is at odds with those of randomized trials which have failed to demonstrate increased function following the treatment of pain with opioid analgesics. This highlights the complexity of the interaction between pain, analgesia and changes in function.
