The sacroiliac joint (SIJ) has been implicated as a potential source of low back and buttock pain. Several types of motion palpation and provocation tests are used to examine the SIJ. It has been suggested that use of a cluster of motion palpation or provocation tests is a more acceptable method than single test to assess SIJ. This study examined the inter- and intra-examiner reliability of single and composites of the motion palpation and provocation tests together. Twenty-five patients between the ages of 20 and 65 years participated. Four motion palpation and three provocation tests were examined three times on both sides (left, right) by two examiners. Kappa coefficient and prevalence-adjusted and bias-adjusted kappa (PABAK) were calculated to evaluate the reliability.
