A sacroiliac joint dysfunction will MOST likely cause pain during which activity?

• A. Sitting
• B. Lying in prone
• C. Walking
• D. Lying in supine

Answer: (C)

Pain from sacroiliac joint dysfunction is typically triggered by activities that load the pelvis and transfer forces through the SI joints. During walking, the pelvis and sacrum undergo dynamic movement and load transfer with each step, putting repetitive stress directly through the SI joints. This loading and small pelvic movements irritate the dysfunctional joint, producing pain. In contrast, lying down (prone or supine) unloads the joint, often reducing pain, and while sitting can irritate SI pain depending on posture, it usually involves less dynamic loading than walking. So the activity that most commonly provokes pain is walking.
