Which of the following tests is NOT included in the sacroiliac cluster?

The infraspinatus test is not part of the sacroiliac cluster because it is specifically used to assess the integrity of the rotator cuff, particularly the infraspinatus muscle, which is located in the shoulder region. The sacroiliac joint cluster, on the other hand, consists of tests designed to evaluate hip and pelvis-related dysfunctions, focusing on the sacroiliac joint itself.

The tests commonly included in the sacroiliac cluster, such as distraction, thigh thrust, and compression, are specifically aimed at reproducing pain related to the SI joint and assessing its stability and function. These tests utilize maneuvers that apply forces to the pelvis and sacroiliac joint area, which helps in diagnosing conditions that may cause pain in that region. Thus, the infraspinatus test does not align with the purpose and anatomical focus of the sacroiliac cluster.
