Yocum Test
What is Yocum test?
Yocum Test is used to evaluate the subacromial impingement syndrome of the shoulder.
See Also: Neer Test
How do you perform the Yocum Test?
With the patient sitting/ standing the hand of the patient is placed on the opposite shoulder and the elbow of the tested side is passively raised up by the examiner.

What does a positive Yocum Test mean?
The test is positive if pain is elicited during this maneuver.
Accuracy
A study on 30 patients with new onset of shoulder pain (the reference standard was subacromial impingement confirmed by MRI), the sensitivity and specificity was:
- Sensitivity: 79%
- Specificity: 40%
and for subacromial bursitis confirmed by MRI, the sensitivity and specificity was 80% and 36%, respectively.
A study comparing the Neer test, Hawkins Kennedy test, and Yocum test found all three to demonstrate a high sensitivity for diagnosing subacromial impingement.
