Background and Aim: The reliability of manual tests of the Sacroiliac Joint (SIJ) is important in that they are frequently used in the assessment of this region for which there is no successful paraclinical exam. The aim of the present study was to measure the diagnostic stability of some of the SIJ manual tests as well as to compare it between symptomatic and asymptomatic individuals.
Materials and Methods: A total of 17 examiners assessed the symmetry of the position of bilateral ILAs and PSISs in prone lying, PSISs in standing as well as the motion of PSISs in standing flexion test on two individuals (one symptomatic and one asymptomatic). The diagnostic stability of the landmarks was computed using X2 and Bayes factor. Examiners were blinded about participants' symptoms.
Results: The results revealed that X2 and Bayes factor were 4.76 and 12.28 for ILAs, 9.94 and 277.52 for PSISs in prone lying, and 9.30 and 241.15 for PSISs in standing and standing flexion test, respectively.
Conclusion: The diagnostic stability of the PSIS in prone lying was the highest and the diagnostic stability of the ILA was the lowest. The diagnostic stability of symptomatic participant was higher than that of the asymptomatic participant. Accordingly, the probability of false postive outcome of the tests is high in asymptomatic individual. Therefore, prior to static palpation tests in the physical examination, it is better to perform pain provocation tests in order to confirm the existence of the SIJ dysfunction.
