A positive Faber test is determined by specific findings during the physical examination maneuver.
Understanding the Faber Test
The Faber test, also known by its acronym FABER (Flexion, Abduction, External Rotation), is a common orthopedic test used to assess the hip joint and the sacroiliac joint. It involves positioning the patient's leg in a specific manner. While the exact procedure for performing the test involves flexing, abducting, and externally rotating the hip, the positivity of the test is defined by the patient's response.
What Constitutes a Positive Result?
According to the provided reference, a positive test is identified by two key criteria:
- Reproduction of the patient's pain: If the movement performed during the Faber test causes the patient to experience the pain they have been reporting, this is considered a positive finding.
- Limitation of range of movement: If the clinician is unable to achieve the expected or normal range of motion when performing the test due to stiffness, pain, or other restriction, this also indicates a positive test.
As stated in the reference: "A positive test is one that reproduces the patient's pain or limits their range of movement."
Here's a simple breakdown of the criteria for a positive test:
| Criterion | Description |
|---|---|
| Pain Provocation | The test maneuver brings on or increases the patient's reported pain. |
| Restricted Movement | The leg's range of motion is noticeably limited compared to the unaffected side or expected range. |
Implications of a Positive Test
A positive Faber test suggests there may be an issue originating from the hip joint, the sacroiliac joint, or surrounding structures such as ligaments or muscles. Further examination and imaging may be necessary to determine the specific cause of the pain or limited movement.
