Only controlled intra-articular zygapophyseal joint (ZJ) injections or medial branch blocks can diagnose ZJ-mediated low back pain. The low prevalence of ZJ pain implies that identification of clinical predictors of a positive response to a screening block is needed. ⋯ A negative extension rotation test, the centralization phenomenon, and four CPRs effectively rule out pain ablation after screening ZJ block. One CPR generates a fivefold improvement in posttest probability of a negative or positive response to ZJ block.

Randomized Controlled TrialDoes flexion-distraction help treat chronic low back pain?

Systematic review. ⋯ Based on the current evidence, intermittent or continuous traction as a single treatment for LBP cannot be recommended for mixed groups of patients with LBP with and without sciatica. Neither can traction be recommended for patients with sciatica because of inconsistent results and methodological problems in most of the studies involved. However, because high-quality studies within the field are scarce, because many are underpowered, and because traction often is supplied in combination with other treatment modalities, the literature allows no firm negative conclusion that traction, in a generalized sense, is not an effective treatment for patients with LBP.

Cross-cultural translation and psychometric testing were performed. ⋯ The Persian versions of the ODI, RDQ, and QDS are reliable and valid instruments to measure functional status in Persian-speaking patients with LBP. They are simple and fast scales, and the use of them can be recommended in a clinical setting and future outcome studies in Iran.

Psychometric testing of a translated, culturally adapted questionnaire. ⋯ The ODI-G is valid, reliable, and responsive. It may be used to measure current state as well as changes in health status, and allows for cross-cultural comparisons. Further research comparing the 2 versions in German language seems to be necessary.
