Abstract
The literature recommended the use of a large number of clinical tests of the sacroiliac joint (SIJ). The reliability and validity of several of the SIJ tests, individually or in combination, have been investigated or discussed by a number of authors, with poor outcomes being claimed in several cases. With respect to some of the tests, the literature included differing accounts concerning the constitution of a positive result to the test. The definitions of a positive result of many of the SIJ tests were imprecise. These differences and lack of precision might contribute to the poor intertester reliability of the tests concerned. The same subject could be assessed as being positive on a particular test by one investigator using one set of criteria, and negative on the same test by another investigator using a different set of criteria. Greater precision and standardisation of definition was recommended.
