Shoulder special tests quiz
Questions use only the figures on this library's test pages.
Last updated 30 October 2026. 8 questions. Each answer links to the test page it comes from; the region's tests are listed on the Shoulder & upper arm cheat sheet.
Terms such as sensitivity, specificity, LR+ and LR− are explained in the glossary. A likelihood ratio above about 5 or below about 0.2 is doing real work; between 2 and 0.5 it is barely worth the time.
Question 1 of 8
Which of these tests best rules out rotator cuff tear?
- Full can test
- External rotation lag sign
- Drop arm test
- Empty can / Jobe's test
Show the answer
Answer: D. Empty can / Jobe's test. Empty can / Jobe's test has the lowest LR−, 0.19. The others: Full can test 0.37, Drop arm test 0.79, External rotation lag sign 0.92. See the test
Question 2 of 8
How far does a positive apprehension test move the probability of anterior instability?
- Up clearly: it is doing real work (LR+ above about 5)
- Up a little: a small shift (LR+ between about 2 and 5)
- Barely: it is barely worth the time (LR+ below about 2)
- Down: a positive result makes it less likely
Show the answer
Answer: A. Up clearly: it is doing real work (LR+ above about 5). Apprehension test: LR+ 20.2. Its page: “a strong rule-in: a positive result makes the diagnosis much more likely.” See the test
Question 3 of 8
How far does a positive full can test move the probability of rotator cuff tear?
- Up clearly: it is doing real work (LR+ above about 5)
- Up a little: a small shift (LR+ between about 2 and 5)
- Barely: it is barely worth the time (LR+ below about 2)
- Down: a positive result makes it less likely
Show the answer
Answer: B. Up a little: a small shift (LR+ between about 2 and 5). Full can test: LR+ 3.75. Its page: “a small shift: a positive result nudges the diagnosis up, but does not settle it.” See the test
Question 4 of 8
How far does a positive Hawkins–Kennedy sign move the probability of subacromial pain?
- Up clearly: it is doing real work (LR+ above about 5)
- Up a little: a small shift (LR+ between about 2 and 5)
- Barely: it is barely worth the time (LR+ below about 2)
- Down: a positive result makes it less likely
Show the answer
Answer: C. Barely: it is barely worth the time (LR+ below about 2). Hawkins–Kennedy sign: LR+ 1.64. Its page: “barely informative: a positive result changes little.” See the test
Question 5 of 8
What counts as a positive apprehension test?
- Sudden return of apprehension at the release.
- Reproduction of the patient's familiar pain during the rotation.
- The apprehension settles and more external rotation is tolerated.
- Apprehension, the feeling that the shoulder will slip; pain alone does not count.
Show the answer
Answer: D. Apprehension, the feeling that the shoulder will slip; pain alone does not count. The Apprehension test page: “Apprehension, the feeling that the shoulder will slip; pain alone does not count.” See the test
Question 6 of 8
What counts as a positive drop arm test?
- The patient cannot rotate outward and adopts the characteristic hornblower's posture.
- The hand cannot be lifted, or only with trick movement.
- The arm drops or cannot be lowered with control, usually around 90°.
- The hand drifts back towards neutral (a lag).
Show the answer
Answer: C. The arm drops or cannot be lowered with control, usually around 90°. The Drop arm test page: “The arm drops or cannot be lowered with control, usually around 90°.” See the test
Question 7 of 8
Starting at 30% for anterior instability, what is the probability after a positive relocation test?
- 62%
- 90%
- 82%
- 71%
Show the answer
Answer: C. 82%. From the ladder on the Relocation test page: a starting 30% becomes 82% after a positive (LR+ 10.4: a strong rule-in). See the test
Question 8 of 8
Starting at 30% for rotator cuff tear, what is the probability after a positive drop arm test?
- 50%
- 25%
- 82%
- 73%
Show the answer
Answer: D. 73%. From the ladder on the Drop arm test page: a starting 30% becomes 73% after a positive (LR+ 6.45: a moderate rule-in). See the test
