Description[edit | edit source]
Test Item Clusters (TIC) is a group of special tests which are developed to facilitate clinical decision making by improving diagnostic utility. Laslett et al investigated the diagnostic power of pain provocation sacroiliac joint (SIJ) tests individually and in various combinations, in relation to a diagnostic injection. The tests employed in this study were: distraction, right sided thigh thrust, right sided Gaenslen's test, compression and sacral thrust. Those tests were chosen due to its acceptable inter-rater reliability. They found that composites of provocation SIJ tests had significant diagnostic utility. Any 2 of 4 selected tests (distraction, thigh thrust, compression, and sacral thrust) have the best predictive power. When all 6 SIJ provocation tests does not reproduce symptoms, the SIJ pathology can be ruled out.
=== Diagnostic Value of Individual SIJ Provocation Tests ===
