BackgroundLumbar supports are used in the treatment of low-back pain patients, to prevent the onset of low-back pain (primary prevention) or to prevent recurrences of a low-back pain episode (secondary prevention).
ObjectivesTo assess the e ects of lumbar supports for prevention and treatment of non-specific low-back pain.
Search methodsWe updated the search in the Cochrane Central Register of Controlled Trials, PubMed, EMBASE, and CINAHL to December 2006. We also screened references given in relevant reviews and identified trials, and contacted experts to identify additional RCTs.
Selection criteriaRandomized controlled trials that reported on any type of lumbar supports as preventive or therapeutic intervention for non-specific lowback pain.
Data collection and analysisOne review author generated the electronic search. Two review authors independently identified trials that met the inclusion criteria. One review author extracted data on the study population, interventions, and final results. The methodological quality and the clinical relevance were independently assessed by two review authors.Because it was not possible to perform a quantitative analysis, we performed a qualitative analysis in which the strength of evidence on the e ectiveness of lumbar supports was classified as strong, moderate, limited, conflicting, or no evidence.
Main resultsSeven preventive studies (14,437 people) and eight treatment studies (1361 people) were included in this updated review. Overall, the methodological quality of the studies was rather low. Only five of the fi een studies met 50% or more of the internal validity items.There was moderate evidence that lumbar supports are not more e ective than no intervention or training in preventing low-back pain, and conflicting evidence whether lumbar supports are e ective supplements to other preventive interventions. It is still unclear if lumbar supports are more e ective than no or other interventions for the treatment of low-back pain.Lumbar supports for prevention and treatment of low back pain (Review)
