What is the purpose of the O’Brien Test?
To assess for a glenoid labral tear and indicate damage to the acromioclavicular ligament.
The test evaluates shoulder joint integrity by observing pain response during specific movements.
Describe the first step of the O’Brien Test.
From a seated or standing position, the patient flexes their shoulder to 90° with the elbow fully extended and the forearm in a supinated position.
This position prepares the shoulder for the subsequent movements involved in the test.
What movement does the patient perform in step two of the O’Brien Test?
The patient horizontally adducts the arm across the body while internally rotating the shoulder joint.
This movement is crucial for assessing the labrum and potential pain response.
What happens in step three of the O’Brien Test?
The practitioner applies a downward force to the distal arm as the patient resists in the full horizontally adducted position.
This resistance is used to evaluate pain related to a labral tear.
Describe the modification made in step four of the O’Brien Test.
The forearm is supinated and the shoulder joint is externally rotated as the arm is moved into a full horizontally adducted position.
This modification helps differentiate between types of shoulder injuries.
What does a positive O’Brien Test indicate?
Pain or clicking inside the shoulder joint in step two that is eliminated or decreased in step four suggests a probable labral tear.
This response helps in diagnosing specific shoulder injuries.
What does pain on top of the shoulder at the AC joint indicate during the O’Brien Test?
It may indicate acromioclavicular ligament damage.
Further assessment with other tests is recommended if this pain is observed.
Name two other tests that should be considered if AC joint pain is indicated.
- Acromioclavicular Horizontal Adduction Test
- Acromioclavicular Shear Test
These tests provide additional insights into the condition of the acromioclavicular joint.
