In Standing Flexion Test interpretation, what does one PSIS moving more cranially suggest?

• A. One PSIS moving more cranially suggests SI dysfunction
• B. Both PSIS move equally indicating SI dysfunction
• C. PSIS movement indicates hip pathology
• D. PSIS movement is unaffected by SI status

Answer: (A)

The standing flexion test looks at how the PSISs move when you bend forward. Normally they rise in sync. If one PSIS climbs higher (moves more cranially) than the other, it points to sacroiliac joint dysfunction on that same side. The abnormal cephalad movement reflects restricted motion at the SI joint on that side, altering how the pelvis components move together during flexion. So, a PSIS that moves more cranially indicates SI dysfunction on that side. The other ideas—equal movement indicating SI dysfunction, movement indicating hip pathology, or movement being unrelated to SI status—don’t fit what this test measures.
