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
SI Joint Injections
The injection helps determine if the SI joint is the specific source of your pain. If the steroid injection provides relief, then the SI joint can be confirmed as the source of your pain
- Two (2) positive Diagnostic SI Joint injections
- One (1) Therapeutic SI Joint Injection
- Both showing 75% relief, Duration not specified
- Both showing 75% relief, Duration not specified
- Do note: Private insurance can vary in requirement for pain relief.

Test #4
Imaging
