Is PsiF right for your patient?
Test #1
The Fortin Finger Test
To begin diagnosing SI joint dysfunction, the patient must be able to pinpoint the area where the pain originates. This is typically done through the Fortin Finger Test, where the patient points to the PSIS as the most prominent landmark where the pain originates. It's important to note that while the pain may radiate, it must originate near the PSIS for the test to be positive.
Test #2
Physical Exam
There must be a positive response on THREE physical examination tests, including:
- Faber Test
- Thigh High Thrust Test
- Distraction Test
- Gaenslen Test
Test #3
