Comparative Study
Clinimetric testing of three self-report outcome measures for low back pain patients in Brazil: which one is the best?
Translation, cross-cultural adaptation, and clinimetric testing of self-report outcome measures. ⋯ The results from this study demonstrate that the Brazilian-Portuguese versions of the RMDQ, the FRI and the PSFS have similar clinimetric properties to each other and to the original English versions. Of allthe measures tested in this study the PSFS seems the most responsive. These measures will enable international comparisons to be performed, and encourage researchers to include Portuguese speakers in their clinical trials.

ReviewTranscutaneous electrical nerve stimulation (TENS) versus placebo for chronic low-back pain.
Transcutaneous electrical nerve stimulation (TENS) was introduced more than 30 years ago as a therapeutic adjunct to the pharmacological management of pain. However, despite widespread use, its effectiveness in chronic low-back pain (LBP) is still controversial. ⋯ At this time, the evidence from the small number of placebo-controlled trials does not support the use of TENS in the routine management of chronic LBP. Further research is encouraged.

The value of sacroiliac pain provocation tests in early active sacroiliitis.
Detection of preradiographic sacroiliitis is important for early diagnosis of ankylosing spondylitis (AS) and related spondyloarthropathies. Magnetic resonance imaging (MRI) is a valuable tool for the diagnosis of sacroiliitis in the early and active stages. The aim of this study is to assess the value of pain provocation tests in detecting early active sacroiliitis. ⋯ Sacroiliac pain provocation tests had acceptable reliability in early active sacroiliitis; however, the discriminating capacity of these tests is poor. A multi-test regimen of three or five sacroiliac pain provocation tests may improve the accuracy of these tests discriminating sacroiliitis from LBP of mechanical origin. Four out of five selected tests or any of the two out of three selected tests have the highest predictive value.
