Standing Flexion Test Special Test

What is it used for?

• Assessing Sacroiliac Joint Stiffness (Hypomobility).

How to Perform

• Position: Patient stands. Examiner places thumbs on both PSIS (back dimples).
• Action: Patient bends forward to touch their toes.

Interpretation of Results

• Positive Test: One thumb moves much higher (more superiorly) than the other.
• Meaning: The side that moves higher is the blocked/stiff joint because it is stuck to the ilium and moves with it.
