Numerous randomized trials have been published investigating the effectiveness of treatments for non-specific low-back pain (LBP) either by trials comparing interventions with a no-treatment group or comparing different interventions. In trials comparing two interventions, often no differences are found and it raises questions about the basic benefit of each treatment. To estimate the effect sizes of treatments for non-specific LBP compared to no-treatment comparison groups, we searched for randomized controlled trials from systematic reviews of treatment of non-specific LBP in the latest issue of the Cochrane Library, issue 2, 2005 and available databases until December 2005. ⋯ Transcutaneous electric nerve stimulation and manipulation had small effect sizes (SMD: 0.22 and 0.35, respectively). As a conclusion, the effect of treatments for LBP is only small to moderate. Therefore, there is a dire need for developing more effective interventions.

Many of the existing low back pain (LBP) questionnaires of function and symptoms have a content of different domains of disability presented as a single sum score, making it difficult to derive changes within a specific domain. The present study describes the development of a clinically derived back-specific questionnaire incorporating both a functional limitation and a symptom scale, with a further subdivision of the symptom scale in separate indices for severity and temporal aspects. The aims of the study were to assess the overall reliability and validity of the new questionnaire, named the Profile Fitness Mapping questionnaire (PFM). ⋯ The present study suggests that the PFM has a high internal consistency and is a valid indicator of symptoms and functional limitations of LBP patients. It offers the combination of a composite total score and the possibility of evaluations within specific domains of disability. Complementary evaluation of test-retest reliability and responsiveness to change is warranted.

Randomized Controlled Trial
A randomised controlled study of reflexology for the management of chronic low back pain.
The use of complementary and alternative medicine (CAM) for the management of chronic low back pain (CLBP) continues to rise. However, questions regarding the efficacy of many CAM therapies for CLBP remain unresolved. The present study investigated the effectiveness of reflexology for CLBP. ⋯ There was a main effect of pain reduction, irrespective of group. Trends in the data illustrated the pain reduction was greatest in the reflexology group. Thus, the current study does not indicate that adding reflexology to usual GP care for the management of CLBP is any more effective than usual GP care alone.

The project to develop a new Japanese Orthopaedic Association (JOA) score rating system for low back disorders, the JOA Back Pain Evaluation Questionnaire (JOABPEQ), is currently in progress. Part 1 of the study selected 25 "candidate" items for use on the JOABPEQ. The purpose of this current Part 2 of the study was to verify the reliability of the questionnaire. ⋯ The tentative questionnaire of the JOABPEQ with 25 items was confirmed to be reliable enough to describe the quality of life of patients who suffer low back disorders.

The aim of this study was to determine the extent to which a number of distinct cognitive factors were differentially related to the levels of pain and disability reported by 183 chronic low back pain (CLBP) patients presenting for physiotherapy. After adjusting for demographics, the cognitive factors accounted for an additional 30% of the variance in pain intensity, with functional self-efficacy (beta=-0.40; P<0.001) and catastrophizing (beta=0.21; P<0.01) both uniquely contributing to the prediction of outcome. The cognitive factors also explained an additional 32% of the variance in disability after adjusting for demographics and pain intensity (total R(2)=0.61). ⋯ Our findings clearly show that there is a strong association between cognitive factors and the levels of pain and disability reported by CLBP patients presenting for physiotherapy. Functional self-efficacy emerged as a particularly strong predictor of both pain intensity and disability. In view of our findings it would seem that targeting specific cognitive factors should be an integral facet of physiotherapy-based treatments for CLBP.
