In the Distraction portion of the Cluster of Laslett, what body parts are bilaterally pressed?

• A. Knees
• B. Hips
• C. ASISs
• D. Shoulders

Answer: (C)

The correct answer involves bilaterally pressing the Anterior Superior Iliac Spines (ASISs) during the Distraction portion of the Cluster of Laslett. This specific technique is used to evaluate sacroiliac joint dysfunction. By applying pressure to the ASISs, the clinician is able to assess how the pelvic region responds to this distraction, which can help identify the presence of any pathological changes or pain that might arise from sacroiliac joint involvement. This test is relevant in the context of determining whether the pain is related to sacroiliac dysfunction or other causes.

The focus on the ASISs distinguishes this test, as pressing the knees or hips would not specifically isolate the movement or stress being assessed in the context of the sacroiliac joints. Similarly, the shoulders do not play a direct role in evaluating lower extremity conditions related to the pelvis and sacroiliac joints, making the ASISs the correct focus for this assessment.
